Dual photography  

E-Print Network (OSTI)

Figure 1: (a) Conventional photograph of a scene, illuminated by a projector with all its pixels turned on. (b) After measuring the light transport between the projector and the camera using structured illumination, our technique is able to synthesize a photorealistic image from the point of view of the projector. This image has the resolution of the projector and is illuminated by a light source at the position of the camera. The technique can capture subtle illumination effects such as caustics and self-shadowing. Note, for example, how the glass bottle in the primal image (a) appears as the caustic in the dual image (b) and vice-versa. Because we have determined the complete light transport between the projector and camera, it is easy to relight the dual image using a synthetic light source (c) or a light modified by a matte captured later by the same camera (d). We present a novel photographic technique called dual photography, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene. With a video projector providing structured illumination, reciprocity permits us to generate pictures from the viewpoint of the projector, even though no camera was present at that location. The technique is completely image-based, requiring no knowledge of scene geometry or surface properties, and

A course in flow visualization: The art and physics of fluid flow  

E-Print Network (OSTI)

In Spring 2003, a new experimental course on flow visualization was offered to a mixed class of Fine Arts Photography and Engineering students. Course content included fluid flow physics, history of photography with respect to the relationship of science and art, as well as flow visualization and photography techniques. Issues such as “What makes an image art? What makes an image scientific? ” were addressed. The class focused on studio/laboratory experiences for mixed teams of students. A range of fluids apparatus were made available, and students also created novel flows. Writeups were required for each image (to the art students ’ shock). Student work was evaluated for both artistic and scientific merit. This course represents a radical departure from normal engineering curricula; typically all fine arts studio courses are specifically excluded. However, the course proved to be very successful in attracting both graduate and undergraduate students, engineering women in particular. One outcome of the course is the recognition by students of the beauty of fluid physics that surrounds us each day, leading to motivation for life-long learning.

On the Relationship Between Dual Photography and Classical Ghost Imaging  

E-Print Network (OSTI)

Classical ghost imaging has received considerable attention in recent years because of its remarkable ability to image a scene without direct observation by a light-detecting imaging device. In this article, we show that this imaging process is actually a realization of a paradigm known as dual photography, which has been shown to produce full-color dual (ghost) images of 3D objects with complex materials without using a traditional imaging device. Specifically, we demonstrate mathematically that the cross-correlation based methods used to recover ghost images are equivalent to the light transport measurement process of dual photography. Because of this, we are able to provide a new explanation for ghost imaging using only classical optics by leveraging the principle of reciprocity in classical electromagnetics. This observation also shows how to leverage previous work on light transport acquisition and dual photography to improve ghost imaging systems in the future.

Table-top computed lighting for practical digital photography  

E-Print Network (OSTI)

Abstract—We apply simplified image-based lighting methods to reduce the equipment, cost, time, and specialized skills required for high-quality photographic lighting of desktop-sized static objects such as museum artifacts. We place the object and a computersteered moving-head spotlight inside a simple foam-core enclosure and use a camera to record photos as the light scans the box interior. Optimization, guided by interactive user sketching, selects a small set of these photos whose weighted sum best matches the user-defined target sketch. Unlike previous image-based relighting efforts, our method requires only a single area light source, yet it can achieve high-resolution light positioning to avoid multiple sharp shadows. A reduced version uses only a handheld light and may be suitable for battery-powered field photography equipment that fits into a backpack. Index Terms—Image-based lighting, enclosure lighting, handheld lighting, controllable lighting, digital photography. 1

A method of preparing nuclear track emulsions having mean grain sizes less than 0.1 microns is described. The method comprises adding silver nitrate to potassium bromide at a rate at which there is always a constant, critical excess of silver ions. For minimum size grains, the silver ion concentration is maintained at the critical level of about pAg 2.0 to 5.0 during prectpitation, pAg being defined as the negative logarithm of the silver ion concentration. It is preferred to eliminate the excess silver at the conclusion of the precipitation steps. The emulsion is processed by methods in all other respects generally similar to the methods of the prior art. (AEC)

Pelletization of fine coals  

SciTech Connect

The present research project attempts to provide a basis to determine the pelletizability of fine coals, to ascertain the role of additives and binders and to establish a basis for binder selection. Currently, there are no established techniques for determining the quality of coal pellets. Our research is intended to develop a series of tests on coal pellets to measure their storage characteristics, transportability, ease of gasification and rate of combustion. Information developed from this research should be valuable for making knowledgeable decisions for on-time plant design, occasional binder selection and frequent process control during the pelletization of coal fines. During the last quarter, we continued the batch pelletization studies on Upper Freeport coal. The results as presented in that last quarterly report (April 1991) indicated that the surface conditions on the coal particle influenced the pelletizing growth rates. For example, a fresh (run of mine) sample of coal will display different pelletizing growth kinetics than a weathered sample of the same coal. Since coal is a heterogeneous material, the oxidized product of coal is equally variable. We found it to be logistically difficult to consistently produce large quantities of artificially oxidized coal for experimental purposes and as such we have used a naturally weathered coal. We have plans to oxidize coals under controlled oxidizing conditions and be able to establish their pelletizing behavior. The next phase of experiments were directed to study the effect of surface modification, introduced during the coal cleaning steps, on pelletizing kinetics. Accordingly, we initiated studies with two additives commonly used during the flotation of coal: dextrin (coal depressant) and dodecane (coal collector).

High-speed Photography of Pyrotechnic Materials and Components with a Coppper Vapor Laser  

SciTech Connect

The evaluation of the properties of energetic materials, such as burn rate and ignition energy, is of primary importance in understanding their reactions and the functioning of devices containing them. One method for recording such information is high-speed photography at rates of up to 20,000 images per second. When a copper vapor lazer is synchronized with the camera, laser-illuminated images can be recorded that detail the performance of a material or component in a manner never before possible. Recent results from high-speed photography of several pyrotechnic materials and devices will be presented. These include a pyrotechnic torch, laser ignition of high explosives, and a functioning igniter. Equilibrium chemical computations have recently been begun on the pyrotechnic torch to obtain flame compositions and temperatures. The results of these calculations, and their explanation of the change in torch function with composition, will be discussed.

Process As Art Process As Art and Other Misconceptions  

E-Print Network (OSTI)

What is a process? A set of activities that turn inputs into outputs. What is a good process? A process that does what it is supposed to do when it is supposed to do it, reliably. What is a great process? One that is effective and optimally efficient. Are there activities that are not amenable to process? Some think so, we think not. In our work with companies, helping them understand the value of applying process to their marketing/sales activities, we have found resistance for many reasons. These reasons include the feeling that much of what goes on in marketing is art, and therefore resistant to process management. In every case, what we have discovered is that, indeed, some activities in marketing – in reality, in many business activities – require "artists " to produce the desired output. However, that by itself does not make the output art. Van Gogh, Monet, Picasso, and others produced artart as the output of artists. Some art today is produced more mechanistically, and yet nevertheless is art. In virtually all business processes, the output desired is not art, albeit some of that output is produced by artists. That distinction is important, as evident from a recent article in the Harvard Business Review 1 that asks the question, "When Should a Process be Art, Not Science? " The authors argue, "There are

Quantum Fine-Grained Entropy  

E-Print Network (OSTI)

Regarding the strange properties of quantum entropy and entanglement, e.g., the negative quantum conditional entropy, we revisited the foundations of quantum entropy, namely, von Neumann entropy, and raised the new method of quantum fine-grained entropy. With the applications in entanglement theory, quantum information processing, and quantum thermodynamics, we demonstrated the capability of quantum fine-grained entropy to resolve some notable confusions and problems, including the measure of entanglement and quantumness, the additivity conjecture of entanglement of formation etc, and the definition of temperature for single quantum system.

Art Directable Tornadoes  

E-Print Network (OSTI)

Tornado simulations in the visual effects industry have always been an interesting problem. Developing tools to provide more control over such effects is an important and challenging task. Current methods to achieve these effects use either particle systems or fluid simulation. Particle systems give a lot of control over the simulation but do not take into account the fluid characteristics of tornadoes. The other method which involves fluid simulation models the fluid behavior accurately but does not give control over the simulation. In this thesis, a novel method to model tornado behavior is presented. A tool based on this method was also created. The method proposed in this thesis uses a hybrid approach that combines the flexibility of particle systems while producing interesting swirling motions inherent in the fluids. The main focus of the research is on providing easy-to-use controls for art directors to help them achieve the desired look of the simulation effectively. A variety of controls is provided which include the overall shape, path, rotation, debris, surface, swirling motion, and interaction with the environment. The implementation was done in Houdini, which is a 3D animation software whose node based system allows an algorithmic approach to the problem and integrates well with the current tools. The tool allows the user to create animations that reflect the visual characteristics of real tornadoes. The usefulness of the tool was evaluated among participants who had some experience in 3D animation software. The results from the simulation and evaluation feedback reveal that the tool successfully allowed the users to create tornadoes of their choice efficiently.

Does Zeeman's Fine Topology Exist?  

E-Print Network (OSTI)

We work on the family of topologies for the Minkowski manifold M. We partially order this family by inclusion to form the lattice \\Sigma(M), and focus on the sublattice Z of topologies that induce the Euclidean metric space on every time axis and every space axis. We analyze the bounds of Z in the lattice \\Sigma(M), in search for its supremum. Our conclusion --that such a supremum does not belong in Z-- is compared with constructive proofs of existence of the fine topology, defined as the maximum of Z and conceived to play an essential role in contemporary physical theories. Essential mathematical and physical questions arise.

Fine Particle Emissions from Combustion Systems Fine Particle Emissions from Combustion Systems Speaker(s): Allen Robinson Date: November 11, 2005 - 12:00pm Location: 90-3122 Combustion systems such as motor vehicles and power plants are major sources of fine particulate matter. This talk describes some of the changes in fine particle emissions that occur as exhaust from combustion systems mix with background air. This mixing cools and dilutes the exhaust which influences gas-particle partitioning of semi-volatile species, the aerosol size distribution, and the fine particle mass. Dilution sampling is used to characterize fine particle emissions from combustion systems because it simulates the rapid cooling and dilution that occur as exhaust mixes with the atmosphere.

Characterization of energetic devices for thermal battery applications by high-speed photography  

DOE Green Energy (OSTI)

High-speed photography at rates of up to 20,000 images per second was used to measure these properties in thermal battery igniters and also the ignition of thermal battery itself. By synchronizing a copper vapor laser to the high-speed camera, laser-illuminated images recorded details of the performance of a component. Output characteristics of several types of hermetically-sealed igniters using a TiH{chi}/KCIO{sub 4} pyrotechnic blend were measured as a function of the particle size of the pyrotechnic fuel and the closure disc thickness. The igniters were filmed under both ambient (i.e., unconfined) and confined conditions. Recently, the function of the igniter in a cut-away section of a ``mock`` thermal battery has been filmed. Partial details of these films are discussed in this paper, and selected examples of the films will be displayed via video tape during the presentation of the paper.

The maximum time interval of time-lapse photography for monitoring construction operations  

E-Print Network (OSTI)

Many construction companies today utilize webcams on their jobsites to monitor and record construction operations. Jobsite monitoring is often limited to outdoor construction operations due to lack of mobility of wired webcams. A wireless webcam may help monitor indoor construction operations with enhanced mobility. The transfer time of sending a photograph from the wireless webcam, however, is slower than that of a wired webcam. It is expected that professionals may have to analyze indoor construction operations with longer interval time-lapse photographs if they want to use a wireless webcam. This research aimed to determine the maximum time interval for time-lapse photos that enables professionals to interpret construction operations and productivity. In order to accomplish the research goal, brickwork of five different construction sites was videotaped. Various interval time-lapse photographs were generated from each video. Worker?s activity in these photographs was examined and graded. The grades in one-second interval photographs were compared with the grades of the same in longer time interval photographs. Error rates in observing longer time-lapse photographs were then obtained and analyzed to find the maximum time interval of time-lapse photography for monitoring construction operations. Research has discovered that the observation error rate increased rapidly until the 60-second interval and its increasing ratio remained constant. This finding can be used to predict a reasonable amount of error rate when observing time-lapse photographs less than 60-second interval. The observation error rate with longer than 60-second interval did not show a constant trend. Thus, the 60-second interval could be considered as the maximum time interval for professionals to interpret construction operations and productivity.

Objective was to follow the cognitive and creative processes demonstrated by student research participants as they integrated a developing knowledge of ``big`` science, as practiced at LLNL, into a personal and idiosyncratic visual, graphical, or multimedia product. The participants, all non-scientists, involved in this process, attended a series of design classes, sponsored by LLNL at the Art Center College of Design in Pasadena CA. As a result of this study, we have become interested in the possibility of similar characteristics between scientists and artists. We have also become interested in the different processes that can be used to teach science to non-scientists, so that they are able to understand and portray scientific information.

System for utilizing oil shale fines  

DOE Patents (OSTI)

A system is provided for utilizing fines of carbonaceous materials such as particles or pieces of oil shale of about one-half inch or less diameter which are rejected for use in some conventional or prior surface retorting process, which obtains maximum utilization of the energy content of the fines and which produces a waste which is relatively inert and of a size to facilitate disposal. The system includes a cyclone retort (20) which pyrolyzes the fines in the presence of heated gaseous combustion products, the cyclone retort having a first outlet (30) through which vapors can exit that can be cooled to provide oil, and having a second outlet (32) through which spent shale fines are removed. A burner (36) connected to the spent shale outlet of the cyclone retort, burns the spent shale with air, to provide hot combustion products (24) that are carried back to the cyclone retort to supply gaseous combustion products utilized therein. The burner heats the spent shale to a temperature which forms a molten slag, and the molten slag is removed from the burner into a quencher (48) that suddenly cools the molten slag to form granules that are relatively inert and of a size that is convenient to handle for disposal in the ground or in industrial processes.

Fine ash formation during pulverized coal combustion  

Science Conference Proceedings (OSTI)

In this study, 15 pulverized coal samples were burnt in a drop-tube furnace to investigate the formation of fine particulates and the influence of coal ash properties on their emission. Coal combustion was carried out at 1673 K in air. Fine particles were collected by a cyclone and a low-pressure impactor. The elemental compositions of the collected particles were analyzed by scanning electron microscopy with energy-dispersive X-ray spectroscopy. We examined the chemical compositions of the fine particles as a function of particle diameter and examined the proportions of the elements in the parent coal samples. We determined that almost all particles less than 0.22 {mu}m in diameter were formed by means of volatilization-condensation of SiO{sub 2} and Al{sub 2}O{sub 3} in the coal. We also demonstrated that the amount of SiO{sub 2} in particle size less than 0.22 {mu}m in diameter was related to the amount of fine included quartz and clay minerals in the parent coal. The primary components of particles greater than 0.76 {mu}m in diameter were SiO{sub 2} and Al{sub 2}O{sub 3}, and as the diameter of the particles decrease, the mass fractions of iron, magnesium, calcium, and phosphorus increased. However, the particle diameter at which this tendency commenced differed depending on the element. Particles between 0.22 and 0.76 {mu}m in diameter were thought to have been formed by the fragmentation and coalescence of particles in the coal and by the simultaneous condensation of volatilized elements onto other particles. 17 refs., 12 figs., 1 tab.

Soldering Small Beads to Fine Wires  

SciTech Connect

One method suggested for soldering small beads to fine wires using a torch to heat the bead, flux, and magnesia brick did not prove entirely satisfactory in this case. It was found the brick would draw heat away from the bead and flux at too fast a rate resulting in a poor weld, a rough surface, and an excessive accumulation of flux on the bead. Secondly, removal of the depleted flux presented a problem when the welding was done on the surface of the brick.

Immobilization of Rocky Flats Graphite Fines Residues  

SciTech Connect

The Savannah River Technology Center (SRTC) is developing an immobilization process for graphite fines residues generated during nuclear materials production activities at the Rocky Flats Environmental Technology Site (Rocky Flats). The continued storage of this material has been identified as an item of concern. The residue was generated during the cleaning of graphite casting molds and potentially contains reactive plutonium metal. The average residue composition is 73 wt percent graphite, 15 wt percent calcium fluoride (CaF2), and 12 wt percent plutonium oxide (PuO2). Approximately 950 kilograms of this material are currently stored at Rocky Flats. The strategy of the immobilization process is to microencapsulate the residue by mixing with a sodium borosilicate (NBS) glass frit and heating at nominally 700 degrees C. The resulting waste form would be sent to the Waste Isolation Pilot Plant (WIPP) for disposal. Since the PuO2 concentration in the residue averages 12 wt percent, the immobilization process was required to meet the intent of safeguards termination criteria by limiting plutonium recoverability based on a test developed by Rocky Flats. The test required a plutonium recovery of less than 4 g/kg of waste form when a sample was leached using a nitric acid/CaF2 dissolution flowsheet. Immobilization experiments were performed using simulated graphite fines with cerium oxide (CeO2) as a surrogate for PuO2 and with actual graphite fines residues. Small-scale surrogate experiments demonstrated that a 4:1 frit to residue ratio was adequate to prevent recovery of greater than 4 g/kg of cerium from simulated waste forms. Additional experiments investigated the impact of varying concentrations of CaF2 and the temperature/heating time cycle on the cerium recovery. Optimal processing conditions developed during these experiments were subsequently demonstrated at full-scale with surrogate materials and on a smaller scale using actual graphite fines.In general, the recovery of cerium from the full-scale waste forms was higher than for smaller scale experiments. The presence of CaF2 also caused a dramatic increase in cerium recovery not seen in the small-scale experiments. However, the results from experiments with actual graphite fines were encouraging. A 4:1 frit to residue ratio, a temperature of 700 degrees C, and a 2 hr heating time produced waste forms with plutonium recoveries of 4 plus/minus 1 g/kg. With an increase in the frit to residue ratio, waste forms fabricated at this scale should meet the Rocky Flats product specification. The scale-up of the waste form fabrication process to nominally 3 kg is expected to require a 5:1 to 6:1 frit to residue ratio and maintaining the waste form centerline temperature at 700 degrees C for 2 hr.

Evaluation of superpave fine aggregate specification  

E-Print Network (OSTI)

Superpave[] was the final product of the Strategic Highway Research Program's (SHRP) asphalt pavement research effort during 1987-93. Some aspects of the Superpave aggregate specifications are not universally accepted. The validity of the fine aggregate angularity (FAA) requirement is questioned by both the owner agencies and the paving and aggregate industries. The FAA test is based on the assumption that more fractured faces will result in higher void content in the loosely compacted sample; however, this is not always true. The aggregate industry has found that cubical shaped particles, even with 100% fractured faces, may not meet the FAA requirement for high-volume traffic. State agencies are concerned that local materials previously considered acceptable and which have provided good field performance, now cannot meet the Superpave requirements. Twenty three-fine aggregates from different part of the USA were tested using major angularity tests: FAA test, direct shear test, compacted aggregate resistance (CAR) test, image analysis Hough transform, and visual inspection. The results from those tests were compared with the available performance history. The FAA test method does not consistently identify angular, cubical aggregates as high quality materials. There is a fair correlation between the CAR stability value and angle of internal friction (AIF) from direct shear test. No correlation was found between FAA and CAR stability or between FAA and AIF. A good correlation was found between FAA and K-index from Hough transform method. Some cubical crushed aggregates whose FAA values were less than 45 gave very high values of CAR stability, AIF and K-index. The statistical analysis of the SHRP LTPP database reveals that there is no evidence of any good linear relationship between FAA and rutting. Of the methods evaluated, image analysis using Hough transform appears most promising for measuring fine aggregate angularity. Until a replacement method for FAA can be identified, the author recommends that the FAA criteria be lowered from 45. The FAA vs. rutting data analysis should be continued with a larger amount of data as the LTPP SHRP database is expanded.

State of the Art Power-in Tube Niobium-Tin Superconductors  

Science Conference Proceedings (OSTI)

Powder-in-Tube (PIT) processed Niobium-Tin wires are commercially manufactured for nearly three decades and have demonstrated a combination of very high current density (presently up to 2500 A mm{sup -2} non-Cu at 12 T and 4.2 K) with fine (35 {micro}m), well separated filaments. We review the developments that have led to the present state of the art PIT Niobium-Tin wires, discuss the wire manufacturing and A15 formation processes, and describe typical superconducting performance in relation to magnetic field and strain. We further highlight successful applications of PIT wires and conclude with an outlook on possibilities for further improvements in the performance of PIT Niobium-Tin wires.

Stored carbon partly fuels fine-root respiration but is not used for production of new fine roots  

SciTech Connect

The relative use of new photosynthate compared to stored C for the production and maintenance of fine roots, and the rate of C turnover in heterogeneous fine-root populations, are poorly understood. We followed the relaxation of a 13C tracer in fine roots in a Liquidambar styraciflua plantation at the conclusion of a free-air CO2 enrichment experiment. Goals included quantifying the relative fractions of new photosynthate versus stored C used in root growth and root respiration, as well as the turnover rate of fine-root C fixed during [CO2] fumigation. New fine-root growth was largely from recent photosynthate, while nearly one-quarter of respired C was from a storage pool. Changes in the isotopic composition of the fine-root population over two full growing seasons indicated heterogeneous C pools; less than 10% of root C had a residence time < 3 months, while a majority of root C had a residence time > 2 years. Compared to a 1-pool model, a 2-pool model for C turnover in fine roots (with 5 and 0.37 yr-1 turnover times) doubles the fine-root contribution to forest NPP (9-13%) and supports the 50% root-to-soil transfer rate often used in models.

A Finely-Predicted Higgs Boson Mass from A Finely-Tuned Weak Scale  

E-Print Network (OSTI)

If supersymmetry is broken directly to the Standard Model at energies not very far from the unified scale, the Higgs boson mass lies in the range 128-141 GeV. The end points of this range are tightly determined. Theories with the Higgs boson dominantly in a single supermultiplet predict a mass at the upper edge, (141 \\pm 2) GeV, with the uncertainty dominated by the experimental errors on the top quark mass and the QCD coupling. This edge prediction is remarkably insensitive to the supersymmetry breaking scale and to supersymmetric threshold corrections so that, in a wide class of theories, the theoretical uncertainties are at the level of \\pm 0.4 GeV. A reduction in the uncertainties from the top quark mass and QCD coupling to the level of \\pm 0.3 GeV may be possible at future colliders, increasing the accuracy of the confrontation with theory from 1.4% to 0.4%. Verification of this prediction would provide strong evidence for supersymmetry, broken at a very high scale of ~ 10^{14 \\pm 2} GeV, and also for a Higgs boson that is elementary up to this high scale, implying fine-tuning of the Higgs mass parameter by ~ 20-28 orders of magnitude. Currently, the only known explanation for such fine-tuning is the multiverse.

Scientists and artists: ""Hey! You got art in my science! You got science on my art  

SciTech Connect

The pairing of science and art has proven to be a powerful combination since the Renaissance. The combination of these two seemingly disparate disciplines ensured that even complex scientific theories could be explored and effectively communicated to both the subject matter expert and the layman. In modern times, science and art have frequently been considered disjoint, with objectives, philosophies, and perspectives often in direct opposition to each other. However, given the technological advances in computer science and high fidelity 3-D graphics development tools, this marriage of art and science is once again logically complimentary. Art, in the form of computer graphics and animation created on supercomputers, has already proven to be a powerful tool for improving scientific research and providing insight into nuclear phenomena. This paper discusses the power of pairing artists with scientists and engineers in order to pursue the possibilities of a widely accessible lightweight, interactive approach. We will use a discussion of photo-realism versus stylization to illuminate the expected beneficial outcome of such collaborations and the societal advantages gained by a non-traditional pa11nering of these two fields.

NETL: Ambient Monitoring - Southern Fine Particulate Monitoring Project  

NLE Websites -- All DOE Office Websites (Extended Search)

Southern Fine Particulate Monitoring Project (SRI) Southern Fine Particulate Monitoring Project (SRI) Southern Research Institute (SRI), Birmingham, AL, is operating a research station in North Birmingham for monitoring fine particulate matter (PM2.5) that exists in that part of the Deep South. The station will be a core PM2.5 mass monitoring and chemical speciation station in the nationwide EPA PM2.5 network. As such, it will be a complement and supplement to DOE-NETL's other ongoing projects for monitoring fine particulate matter in the upper Ohio River valley. Locating additional monitoring equipment in the Deep South will fill an important gap in the national particulate monitoring effort. The region's topography, weather patterns, and variety of emission sources may affect the chemical make-up and airborne transport of fine particles in ways that are different than in other parts of the country. The project's results will support DOE's comprehensive program to evaluate ambient fine particulate matter through better understanding of the chemical and physical properties of these materials.

Inverse Lighting for Photography  

E-Print Network (OSTI)

We introduce a technique for improving photographs using inverse lighting, a new process based on algorithms developed in computer graphics for computing the reflection of light in 3D space. From a photograph and a 3D surface model for the object pictured, inverse lighting estimates the directional distribution of the incident light. We then use this information to process the photograph digitally to alter the lighting on the object. Inverse lighting is a specific example of the general idea of inverse rendering. This refers to the practice of using the methods of computer graphics, which normally are used to render images from scene information, to infer scene information from images. Our system uses physically based rendering technology to construct a linear least squares system that we solve to find the lighting. As an application, the results are then used to simulate a change in the incident light in the photograph. An implementation is described that uses 3D models from a laser...

Fine Structure of Dark Energy and New Physics  

E-Print Network (OSTI)

Following our recent work on the cosmological constant problem, in this letter we make a specific proposal regarding the fine structure (i.e., the spectrum) of dark energy. The proposal is motivated by a deep analogy between the blackbody radiation problem, which led to the development of quantum theory, and the cosmological constant problem, which we have recently argued calls for a conceptual extension of the quantum theory. We argue that the fine structure of dark energy is governed by a Wien distribution, indicating its dual quantum and classical nature. We discuss a few observational consequences of such a picture of dark energy.

ROTARY FILTER FINES TESTING FOR SMALL COLUMN ION EXCHANGE  

SciTech Connect

SRNL was requested to quantify the amount of 'fines passage' through the 0.5 micron membranes currently used for the rotary microfilter (RMF). Testing was also completed to determine if there is any additional benefit to utilizing a 0.1 micron filter to reduce the amount of fines that could pass through the filter. Quantifying of the amount of fines that passed through the two sets of membranes that were tested was accomplished by analyzing the filtrate by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) for titanium. Even with preparations to isolate the titanium, all samples returned results of less than the instrument's detection limit of 0.184 mg/L. Test results show that the 0.5 micron filters produced a significantly higher flux while showing a negligible difference in filtrate clarity measured by turbidity. The first targeted deployment of the RMF is with the Small Column Ion Exchange (SCIX) at the Savannah River Site (SRS). SCIX uses crystalline silicotitanate (CST) to sorb cesium to decontaminate a clarified salt solution. The passage of fine particles through the filter membranes in sufficient quantities has the potential to impact the downstream facilities. To determine the amount of fines passage, a contract was established with SpinTek Filtration to operate a 3-disk pilot scale unit with prototypic filter disk and various feeds and two different filter disk membranes. SpinTek evaluated a set of the baseline 0.5 micron filter disks as well as a set of 0.1 micron filter disks to determine the amount of fine particles that would pass the membrane and to determine the flux each set produced. The membrane on both disk sets is manufactured by the Pall Corporation (PMM 050). Each set of disks was run with three feed combinations: prototypically ground CST, CST plus monosodium titanate (MST), and CST, MST, plus Sludge Batch 6 (SB6) simulant. Throughout the testing, samples of the filtrate were collected, measured for turbidity, and sent back to SRNL for analysis to quantify the amount of fines that passed through the membrane. It should be noted that even though ground CST was tested, it will be transferred to the Defense Waste Processing Facility (DWPF) feed tank and is not expected to require filtration.

Mimbres rock art: a graphic legacy of cultural expression  

E-Print Network (OSTI)

Rock art abounds along the Mimbres River banks and drainage tributaries reflecting the rich cultural remains of the ancient Mimbres people. The Mimbres are a well established cultural group who lived in southwest New Mexico and northern Mexico from A.D. 200 and A.D. 1150. Physical remains of pithouses, pueblos, irrigation systems, artifacts, and rock art have survived the years to provide clues for contemporary understanding of this prehistoric culture and society. Knowledge of the symbolism and belief system has eluded understanding or remained sketchy as a result of examining only physical remains. Based on the hypothesis that by studying the archaeological record and the established characteristics of cultures with origins similar to those of the Mimbres, then assumptions can be made and applied to the understanding of the symbolism, purpose, and use of the rock art for the Mimbres. Specific to this study is the rock art adjacent to and within a one and one-half mile radius of the NAN Ranch Ruin. Research reveals how the rock art of the NAN Ranch Ruin connects to: 1) cultural context to other regional systems, 2) spatial context within the landscape, 3) temporal context with respect to Mimbres development, and 4) symbolic context, tying the rock art to its environment and revealing it as a living part of the universe as it fits into the world view of those who created it.

Three new approaches to the problem of dewatering fine coal  

Science Conference Proceedings (OSTI)

The increased use of continuous miners and longwall shearers have made fine coal a growing proportion of preparation plant feed. Increased crushing within the plant itself to facilitate ash and sulfur removal further tips the size consist towards the fine end of the scale. Of itself there is nothing intrinsically wrong with fine coal, but the disproportionately large quantity of surface moisture entrained with it creates costly problems. Clark D. Harrison of the Electric Power Research Institute (EPRI), Homer City, PA, and James R. Cavalet of Science Applications International Corp., Homer City, have quantified the reasons for fine coal drying. According to their calculations an extra 1% moisture can add from $310,000 to $1 million per year to transport costs. The $310,000 (case 1) would be true for a power plant using 3.1 million tpy at a plant that is 250 miles from its source, and the $1 million (case 2) is a power plant that is 1,000 miles from its source and using 2.5 million tpy. Extra water also means extra heat used and wasted to vaporize this water, an additional avoidable expense of $700,000 for case 1 and $560,000 for case 2. There are also the uncalculated wet-coal-produced costs of plugged pulverizers, plugged chutes and frozen coal. Perhaps the figure that brings the deleterious effects of wet coal closest to home for a preparation plant manager is that a 1% increase in moisture can offset a 4.5% decrease in ash. In considering how to remove excess water, mechanical drying has advantages over thermal drying in that it produces no air pollution and is not as capital intensive, but unfortunately it is also not as effective.

Characteristics of fine particle growth events observed above a forested Characteristics of fine particle growth events observed above a forested ecosystem in the Sierra Nevada Mountains of California Title Characteristics of fine particle growth events observed above a forested ecosystem in the Sierra Nevada Mountains of California Publication Type Journal Article Year of Publication 2006 Authors Lunden, Melissa M., Douglas R. Black, Megan McKay, Kenneth L. Revzan, Allen H. Goldstein, and Nancy J. Brown Journal Aerosol Science and Technology Volume 40 Start Page 373 Issue 5 Pagination 373-388 Date Published 02/2006 ISSN 0278-6826 (Print), 1521-7388 (Online) Abstract Atmospheric aerosols from natural and anthropogenic processes have both primary and secondary origins, and can influence human health, visibility, and climate. One key process affecting atmospheric concentrations of aerosols is the formation of new particles and their subsequent growth to larger particle sizes. A field study was conducted at the Blodgett Forest Research Station in the Sierra Nevada Mountains of California from May through September of 2002 to examine the effect of biogenic volatile organic compounds on aerosol formation and processing. The study included in-situ measurements of concentration and biosphere-atmosphere flux of VOCs, ozone, aerosol size distribution, aerosol physical and optical properties, and meteorological variables. Fine particle growth events were observed on approximately 30 percent of the 107 days with complete size distribution data. Average particle growth rates measured during these events were 3.8 ± 1.9 nm hr-1. Correlations between aerosol properties, trace gas concentrations, and meteorological measurements were analyzed to determine conditions conducive to fine particle growth events. Growth events were typically observed on days with a lesser degree of anthropogenic influence, as indicated by lower concentrations of black carbon, carbon monoxide, and total aerosol volume. Days with growth events also had lower temperatures, increased wind speeds, and larger momentum flux. Measurements of ozone concentrations and ozone flux indicate that gas phase oxidation of biogenic volatile organic compounds occur in the canopy, strongly suggesting that a significant portion of the material responsible for the observed particle growth are oxidation products of naturally emitted very reactive organic compounds.

Process for preparing fine grain titanium carbide powder  

DOE Patents (OSTI)

A method for preparing finely divided titanium carbide powder in which an organotitanate is reacted with a carbon precursor polymer to provide an admixture of the titanium and the polymer at a molecular level due to a crosslinking reaction between the organotitanate and the polymer. The resulting gel is dried, pyrolyzed to drive off volatile components and provide carbon. The resulting solids are then heated at an elevated temperature to convert the titanium and carbon to high-purity titanium carbide powder in a submicron size range.

Hydraulic fracturing method employing a fines control technique  

SciTech Connect

A method is described for controlling fines or sand in an unconsolidated or loosely consolidated formation or reservoir penetrated by at least one wellbore where hydraulic fracturing is used in combination with control of the critical salinity rate and the critical fluid flow velocity. The method comprises: (a) placing at least one wellbore in the reservoir; (b) hydraulically fracturing the formation via the wellbore with a fracturing fluid which creates at least one fracture; (c) placing a proppant comprising a gravel pack into the fracture; (d) determining the critical salinity rate and the critical fluid flow velocity of the formation or reservoir surrounding the wellbore; (e) injecting a saline solution into the formation or reservoir at a velocity exceeding the critical fluid flow velocity and at a saline concentration sufficient to cause the fines or particles to be transferred and fixed deep wihtin the formation or reservoir without plugging the formation, fracture, or wellbore; and (f) producing a hydrocarbonaceous fluid from the formation or reservoir at a velocity such that the critical flow velocity is not exceeded deep within the formation, fracture, or wellbore.

Unraveling the Excess Air/Coal Fineness Enigma  

E-Print Network (OSTI)

In the use of powered coal as a boiler fuel, the factors involved in heat loss from unburnt carbon in the ash are but partially understood. More finely pulverized coal particles will result in lower carbon-in-ash losses. On the other hand, the finer grind of coal requires a considerably higher energy input to the pulverizing mill. Thus, an optimum balance must be achieved between fuel savings and grinding costs to arrive at the maximum economic savings. If these were the only considerations, the solution would be simple. The problem, however, is compounded by a concurrent reduction in mill capacity as the fineness is increased. In addition, there are marked interactions between coal particle size and excess air as they effect carbon burning rate with its concomitant effect upon carbon-in-ash heat loss. Finally, variability in the excess air will alter the energy supplied to the induced-draft and forced-draft air fans. To generate a greater understanding of the impact of the aforesaid factors, upon potential fuel savings, a computer simulation was developed for the powdered coal boiler. The current paper presents results of exploratory studies using the simulator.

Supercritical fluid molecular spray thin films and fine powders  

DOE Patents (OSTI)

Solid films are deposited, or fine powders formed, by dissolving a solid material into a supercritical fluid solution at an elevated pressure and then rapidly expanding the solution through a short orifice into a region of relatively low pressure. This produces a molecular spray which is directed against a substrate to deposit a solid thin film thereon, or discharged into a collection chamber to collect a fine powder. The solvent is vaporized and pumped away. Solution pressure is varied to determine, together with flow rate, the rate of deposition and to control in part whether a film or powder is produced and the granularity of each. Solution temperature is varied in relation to formation of a two-phase system during expansion to control porosity of the film or powder. A wide variety of film textures and powder shapes are produced of both organic and inorganic compounds. Films are produced with regular textural feature dimensions of 1.0-2.0 .mu.m down to a range of 0.01 to 0.1 .mu.m. Powders are formed in very narrow size distributions, with average sizes in the range of 0.02 to 5 .mu.m.

Hydrogen Atom and Time Variation of Fine-Structure Constant  

E-Print Network (OSTI)

In this paper, we have solved the de Sitter special relativistic ($\\mathcal{SR}_{cR}$-) Dirac equation of hydrogen in the earth-QSO(quasar) framework reference by means of the adiabatic approach. The aspects of geometry effects of de Sitter space-time described by Beltrami metric are explored and taken into account. It is found that the $\\mathcal{SR}_{cR}$-Dirac equation of hydrogen is a time dependent quantum Hamiltonian system. We provide an explicit calculation to justify the adiabatic approach in dealing with this time-dependent system. Since the radius of de Sitter sphere $R$ is cosmologically large, the evolution of the system is very slow so that the adiabatic approximation legitimately works with high accuracy. We conclude that the electromagnetic fine-structure constant, the electron mass and the Planck constant are time variations. This prediction of fine-structure constant is consistent with the presently available observation data. For confirming it further, experiments/observations are required.

Reduction of iron ore fines by coal fines in a packed bed and fluidized bed apparatus: A comparative study  

SciTech Connect

Reduction of iron ore fines by coal fines in packed and fluidized beds has been studied. The investigation includes study of the kinetic aspects of reduction, carbon and sulfur content of the direct reduced iron (DRI) produced, and metallography of the products. For both processes, the kinetic data fit the first-order reaction model. Reduction in a fluidized bed is much faster than in a packed bed system. In both cases, DRI contains a substantial amount of free carbon at the kinetic data fit the first-order reaction model. Reduction in a fluidized bed is much faster than in a packed bed system. In both cases, DRI contains a substantial amount of free carbon at the initial stages of reduction. At the later stages of reduction, the carbon present in the DRI is mainly in the combined state. For identical temperatures and particle sizes, reaction in fluidized bed is much faster compared to that in a packed bed. At any particular degree of reduction, sulfur content in DRI samples produced by fluidized bed reduction is always more than that of DRI samples produced by packed bed reduction. Scanning electron microscopy (SEM) micrographs reveal that metallic whiskers formed during reduction in packed beds only. These whiskers become more prominent at higher temperatures and longer times.

Programmable Differential Delay Circuit With Fine Delay Adjustment  

DOE Patents (OSTI)

Circuitry that provides additional delay to early arriving signals such that all data signals arrive at a receiving latch with same path delay. The delay of a forwarded clock reference is also controlled such that the capturing clock edge will be optimally positioned near quadrature (depending on latch setup/hold requirements). The circuitry continuously adapts to data and clock path delay changes and digital filtering of phase measurements reduce errors brought on by jittering data edges. The circuitry utilizes only the minimum amount of delay necessary to achieve objective thereby limiting any unintended jitter. Particularly, this programmable differential delay circuit with fine delay adjustment is designed to allow the skew between ASICS to be minimized. This includes skew between data bits, between data bits and clocks as well as minimizing the overall skew in a channel between ASICS.

Fine structure constant in the spacetime of a cosmic string  

E-Print Network (OSTI)

We calculate the fine structure constant in the spacetime of a cosmic string. In the presence of a cosmic string the value of the fine structure constant reduces. We also discuss on numerical results. The gravitational properties of cosmic strings are strikingly different from those of non-relativistic linear distributions of matter. To explain the origin of the difference, we note that for a static matter distribution with energymomentum tensor, T µ ? = diag (?, ?p1, ?p2, ?p3) , (1) the Newtonian limit of the Einstein equations become ? 2 ? = 4?G (? + p1 + p2 + p3), (2) where ? is the gravitational potential. For non-relativistic matter, pi ? ? and ? 2 ? = 4?G?. Strings, on the other hand, have a large longitudinal tension. For a straight string parallel to the z-axis, p3 = ??, with p1 and p2 vanish when averaged over the string cross-section. Hence, the righthand side of Eq.(2) vanishes, suggesting that straight strings produce no gravitational forece on surrounding matter. This conclusion is confirmed by a full general-relativistic analysis. Another feature distinguishing cosmic strings from more familiar sources is their relativistic motion. As a result, oscillating loops of string can be strong emitters of gravitational radiation. A gravitating string is described by the combined system of Einstein, Higgs and guage field equations. The problem of solving these coupled equations is formidable and no exact solutions have been found to date. Fortunately, for most cosmological applications the problem can be made tractable by adopting two major simplifications. First, assuming that the string thickness is much smaller than all other relevant dimensions, the string can be 1

Waste Coal Fines Reburn for NOx and Mercury Emission Reduction  

SciTech Connect

Injection of coal-water slurries (CWS) made with both waste coal and bituminous coal was tested for enhanced reduction of NO{sub x} and Hg emissions at the AES Beaver Valley plant near Monaca, PA. Under this project, Breen Energy Solutions (BES) conducted field experiments on the these emission reduction technologies by mixing coal fines and/or pulverized coal, urea and water to form slurry, then injecting the slurry in the upper furnace region of a coal-fired boiler. The main focus of this project was use of waste coal fines as the carbon source; however, testing was also conducted using pulverized coal in conjunction with or instead of waste coal fines for conversion efficiency and economic comparisons. The host site for this research and development project was Unit No.2 at AES Beaver Valley cogeneration station. Unit No.2 is a 35 MW Babcock & Wilcox (B&W) front-wall fired boiler that burns eastern bituminous coal. It has low NO{sub x} burners, overfire air ports and a urea-based selective non-catalytic reduction (SNCR) system for NO{sub x} control. The back-end clean-up system includes a rotating mechanical ash particulate removal and electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber. Coal slurry injection was expected to help reduce NOx emissions in two ways: (1) Via fuel-lean reburning when the slurry is injected above the combustion zone. (2) Via enhanced SNCR reduction when urea is incorporated into the slurry. The mercury control process under research uses carbon/water slurry injection to produce reactive carbon in-situ in the upper furnace, promoting the oxidation of elemental mercury in flue gas from coal-fired power boilers. By controlling the water content of the slurry below the stoichiometric requirement for complete gasification, water activated carbon (WAC) can be generated in-situ in the upper furnace. As little as 1-2% coal/water slurry (heat input basis) can be injected and generate sufficient WAC for mercury capture. During July, August, and September 2007, BES designed, procured, installed, and tested the slurry injection system at Beaver Valley. Slurry production was performed by Penn State University using equipment that was moved from campus to the Beaver Valley site. Waste coal fines were procured from Headwaters Inc. and transported to the site in Super Sacks. In addition, bituminous coal was pulverized at Penn State and trucked to the site in 55-gallon drums. This system was operated for three weeks during August and September 2007. NO{sub x} emission data were obtained using the plant CEM system. Hg measurements were taken using EPA Method 30B (Sorbent Trap method) both downstream of the electrostatic precipitator and in the stack. Ohio Lumex Company was on site to provide rapid Hg analysis on the sorbent traps during the tests. Key results from these tests are: (1) Coal Fines reburn alone reduced NO{sub x} emissions by 0-10% with up to 4% heat input from the CWS. However, the NO{sub x} reduction was accompanied by higher CO emissions. The higher CO limited our ability to try higher reburn rates for further NO{sub x} reduction. (2) Coal Fines reburn with Urea (Carbon enhanced SNCR) decreased NO{sub x} emissions by an additional 30% compared to Urea injection only. (3) Coal slurry injection did not change Hg capture across the ESP at full load with an inlet temperature of 400-430 F. The Hg capture in the ESP averaged 40%, with or without slurry injection; low mercury particulate capture is normally expected across a higher temperature ESP because any oxidized mercury is thought to desorb from the particulate at ESP temperatures above 250 F. (4) Coal slurry injection with halogen salts added to the mixing tank increased the Hg capture in the ESP to 60%. This significant incremental mercury reduction is important to improved mercury capture with hot-side ESP operation and wherever hindrance from sulfur oxides limit mercury reduction, because the higher temperature is above sulfur oxide dew point interference.

HEP/123-qed Fine structure of alpha decay in odd nuclei  

E-Print Network (OSTI)

Using an ? decay level scheme, the fine structure in odd nuclei is explained by taking into account the radial and rotational couplings between the unpaired valence nucleon and the core of the decaying system. It is shown that the experimental behavior of the ? decay fine structure phenomenon is governed by the dynamical characteristics of the system.

Can hidden correlations mimic a variable fine structure constant?  

E-Print Network (OSTI)

Murphy et al. (2003a, MNRAS, 345, 609) claim to find evidence of cosmological variations of the fine structure constant $\\alpha$ in the spectra of intervening QSO absorption line systems. We find that this result is affected by systematic effects. The $\\alpha$ values estimated in individual line systems depend on the set of atomic transitions used and therefore the quoted dependence on the cosmic age may reflect the fact that different sets of transitions are used at different redshifts. A correlation between line shifts and relative optical depths of the atomic transitions is also present. This correlation is very tight for a high-redshift subsample and accounts for the anomalous dispersion of the $\\alpha$ values found by Murphy et al. (2003a) in this subsample. The above correlations are consistent with a scenario in which gravitational redshift, caused by the gravity of the dark halo, contributes to the shift in frequency of individual components. Gravitational redshift causes differential spectral shifts of the same order as magnitude of those measured. In the presence of line misidentification, these shifts can be interpreted in terms of a variable $\\alpha$. In order to verify the gravitational redshift hypothesis, a direct access to Murphy et al. (2003a) data, or to a large amount of new high resolution data, is necessary.

Fine-tuning molecular energy levels by nonresonant laser pulses  

E-Print Network (OSTI)

We evaluate the shifts imparted to vibrational and rotational levels of a linear molecule by a nonresonant laser field at intensities of up to 10^12 W/cm^2. Both types of shift are found to be either positive or negative, depending on the initial rotational state acted upon by the field. An adiabatic field-molecule interaction imparts a rotational energy shift which is negative and exceeds the concomitant positive vibrational shift by a few orders of magnitude. The rovibrational states are thus pushed downward in such a field. A nonresonant pulsed laser field that interacts nonadiabatically with the molecule is found to impart rotational and vibrational shifts of the same order of magnitude. The nonadiabatic energy transfer occurs most readily at a pulse duration which amounts to about a tenth of the molecule's rotational period, and vanishes when the sudden regime is attained for shorter pulses. We applied our treatment to the much studied 87Rb_2 molecule in the last bound vibrational levels of its lowest singlet and triplet electronic states. Our calculations indicate that 15 ns and 1.5 ns laser pulses of an intensity in excess of 5x10^9 W/cm^2 are capable of dissociating the molecule due to the vibrational shift. Lesser shifts can be used to fine tune the rovibrational levels and thereby to affect collisional resonances by the nonresonant light. The energy shifts may be discernible spectroscopically, at a 10 MHz resolution.

Characterization Report for the David Witherspoon Screen Art Site  

SciTech Connect

The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.

E-Print Network (OSTI)

. Network measurements are crucial both to drive research and in network operations. We introduce a taxonomy and survey the state of the art of network measurement. We compare measurements available at the network layer with those available at higher layers, specifically the DNS and the Web. Both the DNS and the Web can be viewed as logical networks; this allows the direct comparison of measurement methods available at these layers with those available at the network layer. We argue that measurement support within the DNS and the Web is insufficient in light of the fact that they affect end-user performance as much as the network layer. We derive some recommendations for the reuse of network layer measurement methods in the DNS and the Web. 1

Bayesian considerations on the multiverse explanation of cosmic fine-tuning  

E-Print Network (OSTI)

The fundamental laws and constants of our universe seem to be finely tuned for life. The various multiverse hypotheses are popular explanations for the fine tuning. This paper reviews the four main suggestions on inference in the presence of possible multiple universes and observer selection effects. Basic identities from probability theory and previously unnoticed conditional dependencies of the propositions involved are used to decide among the alternatives. In the case of cosmic fine-tuning, information about the observation is not independent of the hypothesis. It follows that the observation should be used as data when comparing hypotheses. Hence, approaches that use the observation only as background information are incorrect. It is also shown that in some cases the self-sampling assumption by Bostrom leads to probabilities greater than one, leaving the approach inconsistent. The "some universe" (SU) approach is found wanting. Several reasons are given on why the "this universe" (TU) approach seems to be correct. Lastly, the converse selection effect by White is clarified by showing formally that the converse condition leads to SU and its absence to TU. The overall result is that, because multiverse hypotheses do not predict the fine-tuning for this universe any better than a single universe hypothesis, the multiverse hypotheses fail as explanations for cosmic fine-tuning. Conversely, the fine-tuning data does not support the multiverse hypotheses.

Combustion characterization of the blend of plant coal and recovered coal fines  

SciTech Connect

The overall objective of this proposed research program is to determine the combustion characteristics of the blend derived from mixing a plant coal and recovered and clean coal fines from the pond. During this study, one plant coal and three blend samples will be prepared and utilized. The blend samples will be of a mixture of 90% plant coal + 10% fines, 85% plant coal + 15% fines, 80% plant coal + 20% fines having particle size distribution of 70% passing through {minus}200 mesh size. These samples' combustion behavior will be examined in two different furnaces at Penn State University, i.e., a down-fired furnace and a drop-tube furnace. The down-fired furnace will be used mainly to measure the emissions and ash deposition study, while the drop tube furnace will be used to determine burning profile, combustion efficiency, etc. This report covers the first quarter's progress. Major activities during this period were focused on finding the plants where a demo MTU column will be installed to prepare the samples needed to characterize the combustion behavior of slurry effluents. Also, a meeting was held at Penn State University to discuss the availability of the laboratory furnace for testing the plant coal/recovered coal fines blends.

State of the art of pressurized fluidized bed combustion systems  

SciTech Connect

This report was prepared at the request of the Tennessee Valley Authority (TVA) to clarify the development status of the pressurized fluidized bed combustor (PFBC) and to place in perspective the problems which are yet to be solved before commercialization of the concept is practical. This report, in essence, supersedes the interim report published in 1979, Assessment of the State of the Art of Pressurized Fluidized Bed Combustion Systems. A brief overview of the PFBC concept is included citing potential advantages and disadvantages relative to atmospheric fluidized bed combustion (AFBC) and conventional pulverized coal plants. A survey of existing and developing PFBC experimental facilities is presented in some detail which includes the major accomplishments at the respective facilities. Recent data on plant emissions, turbine/gas cleanup systems, and overall efficiency are provided. Findings of several design studies are also discussed. The results of recent gas turbine and cascade tests have been encouraging although the full assessment of the accomplishments have not been made. The delay in construction of the Grimethorpe plant causes further delay in proof-testing full-size, rotating turbomachinery. Several parameters are recommended for further assessment in design studies including: (1) effect of turbine life on cost of power; and (2) effect of reduced gas turbine inlet temperature and pressure on cost of power.

State-of-the-Art Beta Detection and Dosimetry  

Science Conference Proceedings (OSTI)

The research funded by this NEER grant establishes the framework for a detailed understanding of the challenges in beta dosimetry, especially in the presence of a mixed radiation field. The work also stimulated the thinking of the research group which will lead to new concepts in digital signal processing to allow collection of detection signals and real-time analysis such that simultaneous beta and gamma spectroscopy can take place. The work described herein (with detail in the many publications that came out of this research) was conducted in a manner that provided dissertation and thesis topics for three students, one of whom was completely funded by this grant. The overall benefit of the work came in the form of a dramatic shift in signal processing that is normally conducted in analog pulse shape analysis. Analog signal processing was shown not to be feasible for this type of work; digital signal processing was a must. This, in turn, led the research team to a new understanding of pulse analysis, one in which expands the state-of-the-art in simultaneous beta and gamma spectroscopy with a single detector.

State-of-the-art report on piping fracture mechanics  

Science Conference Proceedings (OSTI)

This report is an in-depth summary of the state-of-the-art in nuclear piping fracture mechanics. It represents the culmination of 20 years of work done primarily in the US, but also attempts to include important aspects from other international efforts. Although the focus of this work was for the nuclear industry, the technology is also applicable in many cases to fossil plants, petrochemical/refinery plants, and the oil and gas industry. In compiling this detailed summary report, all of the equations and details of the analysis procedure or experimental results are not necessarily included. Rather, the report describes the important aspects and limitations, tells the reader where he can go for further information, and more importantly, describes the accuracy of the models. Nevertheless, the report still contains over 150 equations and over 400 references. The main sections of this report describe: (1) the evolution of piping fracture mechanics history relative to the developments of the nuclear industry, (2) technical developments in stress analyses, material property aspects, and fracture mechanics analyses, (3) unresolved issues and technically evolving areas, and (4) a summary of conclusions of major developments to date.

Measurement and Evaluation of Ultra-fine Particle Emissions from Laser  

NLE Websites -- All DOE Office Websites (Extended Search)

Measurement and Evaluation of Ultra-fine Particle Emissions from Laser Measurement and Evaluation of Ultra-fine Particle Emissions from Laser Printers Speaker(s): Tunga Salthammer Date: October 9, 2008 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Hugo Destaillats Several publications have recently appeared which describe the release of ultra-fine particles (UFPs) from hardcopy devices not only in chamber tests but also under real room conditions. Due to assumed health impacts attributed to UFPs this subject currently receives substantial public attention. For the characterization of emitted UFPs from laser printers, different test methods (box chamber tests, flow chamber tests, furnace tests) and analytical techniques (SMPS, FMPS, VHTDMA, GC/MS, Headspace/MS, thermography, etc...) were applied. It could be shown that the release of

Exciton fine-structure splitting of telecom wavelength single quantum dots: statistics and external strain tuning  

E-Print Network (OSTI)

In a charge tunable device, we investigate the fine structure splitting of neutral excitons in single long-wavelength (1.1\\mu m response of the splitting to the external strain, including positive and negative tuning slopes, different tuning ranges, and linear and parabolic dependencies, indicating that these physical parameters depend strongly on the unique microscopic structure of the individual quantum dot. To better understand the experimental results, we apply a phenomenological model describing the exciton polarization and fine-structure splitting under uniaxial strain. The model predicts that, with an increased experimental strain tuning range, the fine-structure can be effectively canceled for select telecom wavelength dots using uniaxial strain. These results are promising for the generation of on-demand entangled photon pairs at telecom wavelengths.

Wind power forecasting : state-of-the-art 2009.  

DOE Green Energy (OSTI)

Many countries and regions are introducing policies aimed at reducing the environmental footprint from the energy sector and increasing the use of renewable energy. In the United States, a number of initiatives have been taken at the state level, from renewable portfolio standards (RPSs) and renewable energy certificates (RECs), to regional greenhouse gas emission control schemes. Within the U.S. Federal government, new energy and environmental policies and goals are also being crafted, and these are likely to increase the use of renewable energy substantially. The European Union is pursuing implementation of its ambitious 20/20/20 targets, which aim (by 2020) to reduce greenhouse gas emissions by 20% (as compared to 1990), increase the amount of renewable energy to 20% of the energy supply, and reduce the overall energy consumption by 20% through energy efficiency. With the current focus on energy and the environment, efficient integration of renewable energy into the electric power system is becoming increasingly important. In a recent report, the U.S. Department of Energy (DOE) describes a model-based scenario, in which wind energy provides 20% of the U.S. electricity demand in 2030. The report discusses a set of technical and economic challenges that have to be overcome for this scenario to unfold. In Europe, several countries already have a high penetration of wind power (i.e., in the range of 7 to 20% of electricity consumption in countries such as Germany, Spain, Portugal, and Denmark). The rapid growth in installed wind power capacity is expected to continue in the United States as well as in Europe. A large-scale introduction of wind power causes a number of challenges for electricity market and power system operators who will have to deal with the variability and uncertainty in wind power generation when making their scheduling and dispatch decisions. Wind power forecasting (WPF) is frequently identified as an important tool to address the variability and uncertainty in wind power and to more efficiently operate power systems with large wind power penetrations. Moreover, in a market environment, the wind power contribution to the generation portofolio becomes important in determining the daily and hourly prices, as variations in the estimated wind power will influence the clearing prices for both energy and operating reserves. With the increasing penetration of wind power, WPF is quickly becoming an important topic for the electric power industry. System operators (SOs), generating companies (GENCOs), and regulators all support efforts to develop better, more reliable and accurate forecasting models. Wind farm owners and operators also benefit from better wind power prediction to support competitive participation in electricity markets against more stable and dispatchable energy sources. In general, WPF can be used for a number of purposes, such as: generation and transmission maintenance planning, determination of operating reserve requirements, unit commitment, economic dispatch, energy storage optimization (e.g., pumped hydro storage), and energy trading. The objective of this report is to review and analyze state-of-the-art WPF models and their application to power systems operations. We first give a detailed description of the methodologies underlying state-of-the-art WPF models. We then look at how WPF can be integrated into power system operations, with specific focus on the unit commitment problem.

An efficient process for recovery of fine coal from tailings of coal washing plants  

SciTech Connect

Gravity concentration of hard lignites using conventional jigs and heavy media separation equipment is prone to produce coal-rich fine tailings. This study aims to establish a fine coal recovery process of very high efficiency at reasonable capital investment and operational costs. The technical feasibility to upgrade the properties of the predeslimed fine refuse of a lignite washing plant with 35.9% ash content was investigated by employing gravity separation methods. The laboratory tests carried out with the combination of shaking table and Mozley multi-gravity separator (MGS) revealed that the clean coal with 18% ash content on dry basis could be obtained with 58.9% clean coal recovery by the shaking table stage and 4.1% clean coal recovery by MGS stage, totaling to the sum of 63.0% clean coal recovery from a predeslimed feed. The combustible recovery and the organic efficiency of the shaking table + MGS combination were 79.5% and 95.5%, respectively. Based on the results of the study, a flow sheet of a high-efficiency fine coal recovery process was proposed, which is also applicable to the coal refuse pond slurry of a lignite washing plant.

Hydrophobic Dewatering of Fine Coal. Topical report, March 1, 1995-March 31, 1997  

Science Conference Proceedings (OSTI)

Many advanced fine coal cleaning technologies have been developed in recent years under the auspices of the U.S. Department of Energy. However, they are not as widely deployed in industry as originally anticipated. An important reason for this problem is that the cleaned coal product is difficult to dewater because of the large surface area associated with fine particles. Typically, mechanical dewatering, such as vacuum filtration and centrifugation, can reduce the moisture to 20-35% level, while thermal drying is costly. To address this important industrial problem, Virginia Tech has developed a novel dewatering process, in which water is displaced from the surface of fine particulate materials by liquid butane. Since the process is driven by the hydrophobic interaction between coal and liquid butane, it was referred to as hydrophobic dewatering (HD). A fine coal sample with 21.4 pm median size was subjected to a series of bench-scale HD tests. It was a mid-vol bituminous coal obtained from the Microcel flotation columns operating at the Middle Fork coal preparation plant, Virginia. All of the test results showed that the HD process can reduce the moisture to substantially less than 10%. The process is sensitive to the amount of liquid butane used in the process relative to the solids concentration in the feed stream. Neither the intensity nor the time of agitation is critical for the process. Also, the process does not require long time for phase separation. Under optimal operating conditions, the moisture of the fine coal can be reduced to 1% by weight of coal.

Youth, Art, and Life on the Border: An Examination of Coping and Support among Participants in a Migrant Art Program  

E-Print Network (OSTI)

This case study examined coping strategies and support systems utilized by 33 children of Hispanic migrant farmworkers from Fabens, Texas. The youth participated in the summer 2011 Creative Kids Incorporated Migrant Program in El Paso, Texas. The study examined how socio-ecological factors, specifically within Creative Kids Inc., help youth to cope with risk factors and aid in the resilience process. This study applied both qualitative and quantitative approaches. The qualitative portion consisted of 12 in-depth program participant interviews, ages 9-15, and observations at Creative Kids Inc. The quantitative portion consisted of a survey that utilized the Brief Adolescent Life Event Scale, the Children Coping Strategies Checklist, and the Multi-Dimensional Support Scale. Thirty-four surveys were distributed, and 33 surveys were analyzed from program participants ages 10-15. The study found the youth were affected by various risk factors within their environment, such as poverty, separation from family, and school. When adapting to stress, most youth utilized behavioral-based distraction strategies (i.e., listening to music and playing outside) and cognitive-based avoidance strategies (i.e., not thinking about their problem) to cope. The youth did not use active coping strategies as often as avoidance strategies. However, some support seeking strategies were mentioned. Most often, youth sought support from parents and older siblings. While the youth sought support from their teachers, it was mainly in regard to school work. Similarly, youth sought support from Creative Kids Inc. staff concerning their art projects. Families were beneficial to youth in the coping process, because they provided youth with opportunities for distracting activities as well as some support. Although the youth strongly enjoyed participating in the Migrant Program, they rarely sought support for personal stressors or problems from the staff. Yet, the program provided youth with opportunities to participate in distracting activities, express their feelings, and seek out support. Despite the lack of literature on children of Hispanic migrant farmworkers and the factors that influence their resilience, this study provided an in-depth description of how they cope with daily life events, what support systems are available to assist in overcoming risks, and provided a basis for understanding the role of support systems in facilitating resiliency among this adolescent group.

Hydrogen from biomass: state of the art and research challenges  

Science Conference Proceedings (OSTI)

The report was prepared for the International Energy Agency (IEA) Agreement on the Production and Utilization of Hydrogen, Task 16, Hydrogen from Carbon-Containing Materials. Hydrogen's share in the energy market is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. Hydrogen production will need to keep pace with this growing market. In the near term, increased production will likely be met by conventional technologies, such as natural gas reforming. In these processes, the carbon is converted to CO2 and released to the atmosphere. However, with the growing concern about global climate change, alternatives to the atmospheric release of CO2 are being investigated. Sequestration of the CO2 is an option that could provide a viable near-term solution. Reducing the demand on fossil resources remains a significant concern for many nations. Renewable-based processes like solar- or wind-driven electrolysis and photobiological water splitting hold great promise for clean hydrogen production; however, advances must still be made before these technologies can be economically competitive. For the near-and mid-term, generating hydrogen from biomass may be the more practical and viable, renewable and potentially carbon-neutral (or even carbon-negative in conjunction with sequestration) option. Recently, the IEA Hydrogen Agreement launched a new task to bring together international experts to investigate some of these near- and mid-term options for producing hydrogen with reduced environmental impacts. This review of the state of the art of hydrogen production from biomass was prepared to facilitate in the planning of work that should be done to achieve the goal of near-term hydrogen energy systems. The relevant technologies that convert biomass to hydrogen, with emphasis on thermochemical routes are described. In evaluating the viability of the conversion routes, each must be put in the context of the availability of appropriate feedstocks and deployment scenarios that match hydrogen to the local markets. Co-production opportunities are of particular interest for near-term deployment since multiple products improve the economics; however, co-product development is not covered in this report. Biomass has the potential to accelerate the realization of hydrogen as a major fuel of the future. Since biomass is renewable and consumes atmospheric CO2 during growth, it can have a small net CO2 impact compared to fossil fuels. However, hydrogen from biomass has major challenges. There are no completed technology demonstrations. The yield of hydrogen is low from biomass since the hydrogen content in biomass is low to being with (approximately 6% versus 25% for methane) and the energy content is low due to the 40% oxygen content of biomass. Since over half of the hydrogen from biomass comes from splitting water in the steam reforming reaction, the energy content of the feedstock is an inherent limitation of the process . The low yield of hydrogen on a weight basis is misleading since the energy conversion efficiency is high. However, the cost for growing, harvesting, and transporting biomass is high. Thus even with reasonable energy efficiencies, it is not presently economically competitive with natural gas steam reforming for stand-alone hydrogen without the advantage of high-value co-products. Additionally, as with all sources of hydrogen, production from biomass will require appropriate hydrogen storage and utilization systems to be developed and deployed. The report also looked at promising areas for further research and development. The major areas for R,D and D are: feedstock preparation and feeding; gasification gas conditioning; system integration; modular systems development; valuable co-product integration; and larger-scale demonstrations. These are in addition to the challenges for any hydrogen process in storage and utilization technologies.

New microtextural criterion for differentiation of compaction and early cementation in fine-grained limestones  

SciTech Connect

Mechanisms of porosity reduction in fine-grained limestones (micrites), the most abundant type of limestone, have been difficult to evaluate because of the fine crystal sizes. Scanning electron microscopy reveals common minute voids termed microfenestrae ({approximately} 1.5-40{mu}m diameter) in Holocene lime muds from all marine carbonate environments studied. Experimental compaction of lime muds greatly reduces abundance of microfenestrae at pressures less than 10 bar. Thus, the abundance of cement-filled microfenestrae in micrites appears to be a widely applicable criterion for recognition of the extent of cementation prior to significant compaction in any given micrite. Microfenestrae in most Phanerozoic micrites studied are about as common as in Holocene lime muds, suggesting that early cementation is a more important mechanism in micrite porosity reduction than recent views have suggested.

Fine-grained authorization for job and resource management usingakenti and the globus toolkit(R)  

SciTech Connect

As the Grid paradigm is adopted as a standard way of sharing remote resources across organizational domains, the need for fine-grained access control to these resources increases. This paper presents an authorization solution for job submission and control, developed as part of the National Fusion Collaboratory, that uses the Globus Toolkit 2 and the Akenti authorization service in order to perform fine-grained authorization of job and resource management requests in a Gridenvironment. At job startup, it allows the system to evaluate a user's Resource Specification Language request against authorization policies on resource usage determining how many CPUs or memory a user can use on a given resource or which executables the user can run based on authorization policies, it allows other virtual organization members to manage the user's job.

Constraints on Field Theoretical Models for Variation of the Fine Structure Constant  

E-Print Network (OSTI)

Recent theoretical ideas and observational claims suggest that the fine structure constant alpha may be variable. We examine a spectrum of models in which alpha is a function of a scalar field. Specifically, we consider three scenarios: oscillating alpha, monotonic time variation of alpha, and time-independent alpha that is spatially varying. We examine the constraints imposed upon these theories by cosmological observations, particle detector experiments, and ``fifth force'' experiments. These constraints are very strong on models involving oscillation, but cannot compete with bounds from the Oklo sub-nuclear reactor on models with monotonic time-like variation of alpha. One particular model with spatial variation is consistent with all current experimental and observational measurements, including those from two seemingly conflicting measurements of the fine structure constant using the many multiplet method on absorption lines.

Is there Correlation between Fine Structure and Dark Energy Cosmic Dipoles?  

E-Print Network (OSTI)

We present a detailed analysis (including redshift tomography) of the cosmic dipoles in the Keck+VLT quasar absorber and in the Union2 SnIa samples. We show that the fine structure constant cosmic dipole obtained through the Keck+VLT quasar absorber sample at $4.1\\sigma$ level is anomalously aligned with the corresponding dark energy dipole obtained through the Union2 sample at $2\\sigma$ level. The angular separation between the two dipole directions is $11.3^\\circ \\pm 11.8^\\circ$. We use Monte Carlo simulations to find the probability of obtaining the observed dipole magnitudes with the observed alignment, in the context of an isotropic cosmological model with no correlation between dark energy and fine structure constant $\\alpha$. We find that this probability is less than one part in $10^6$. We propose a simple physical model (extended topological quintessence) which naturally predicts a spherical inhomogeneous distribution for both dark energy density and fine structure constant values. The model is based on the existence of a recently formed giant global monopole with Hubble scale core which also couples non-minimally to electromagnetism. Aligned dipole anisotropies would naturally emerge for an off-centre observer for both the fine structure constant and for dark energy density. This model smoothly reduces to \\lcdm for proper limits of its parameters. Two predictions of this model are (a) a correlation between the existence of strong cosmic electromagnetic fields and the value of $\\alpha$ and (b) the existence of a dark flow on Hubble scales due to the repulsive gravity of the global defect core (`Great Repulser') aligned with the dark energy and $\\alpha$ dipoles. The direction of the dark flow is predicted to be towards the spatial region of lower accelerating expansion. Existing data about the dark flow are consistent with this prediction.

The HIGGS Boson Mass at 2 Loops in the Finely Tuned Split Supersymmetric Standard Model  

SciTech Connect

The mass of the Higgs boson in the finely tuned Split Supersymmetric Standard Model is calculated. All 1 loop threshold effects are included, in addition to the full RG running of the Higgs quartic coupling through 2 loops. The 2 loop corrections are very small, typically less than 1GeV. The 1 loop threshold corrections to the top yukawa coupling and the Higgs mass generally push the Higgs mass down a few GeV.

Very Fine Aerosols from the World Trade Center Collapse Piles: Anaerobic Incineration  

SciTech Connect

By September 14, three days after the initial World Trade Center collapse, efforts at fire suppression and heavy rainfall had extinguished the immediate surface fires. From then until roughly mid-December, the collapse piles continuously emitted an acrid smoke and fume in the smoldering phase of the event. Knowledge of the sources, nature, and concentration of these aerosols is important for evaluation and alleviation of the health effects on workers and nearby residents. In this paper, we build on our earlier work to ascribe these aerosols to similar processes that occur in urban incinerators. The simultaneous presence of finely powdered (circa 5 {micro}m) and highly basic (pH 11 to 12) cement dust and high levels of very fine (< 0.25 {micro}m) sulfuric acid fumes helps explain observed health impacts. The unprecedented levels of several metals in the very fine mode can be tied to liberation of those metals that are both present in elevated concentrations in the debris and have depressed volatility temperatures caused by the presence of organic materials and chlorine.

Ocean acoustic wave propagation and ray method correspondence: internal wave fine structure  

E-Print Network (OSTI)

Acoustic wave fields propagating long ranges through the ocean are refracted by the inhomogeneities in the ocean's sound speed profile. Intuitively, for a given acoustic source frequency, the inhomogeneities become ineffective at refracting the field beyond a certain fine scale determined by the acoustic wavelength. On the other hand, ray methods are sensitive to infinitely fine features. Thus, it is possible to complicate arbitrarily the ray dynamics, and yet have the wave field propagate unchanged. This feature raises doubts about the ray/wave correspondence. Given the importance of various analyses relying on ray methods, a proper model should, at a minimum, exclude all of the fine structure that does not significantly alter the propagated wave field when the correspondence to the ray dynamics is integral. We develop a simple, efficient, smoothing technique to be applied to the inhomogeneities - a low pass filtering performed in the spatial domain - and give a characterization of its necessary extent as a function of acoustic source frequency. We indicate how the smoothing improves the ray/wave correspondence, and show that the so-called ``ray chaos'' problem remains above a very low frequency (about 15-25 Hz).

Decoherent Histories Quantum Mechanics with One 'Real' Fine-Grained History  

E-Print Network (OSTI)

Decoherent histories quantum theory is reformulated with the assumption that there is one "real" fine-grained history, specified in a preferred complete set of sum-over-histories variables. This real history is described by embedding it in an ensemble of comparable imagined fine-grained histories, not unlike the familiar ensemble of statistical mechanics. These histories are assigned extended probabilities, which can sometimes be negative or greater than one. As we will show, this construction implies that the real history is not completely accessible to experimental or other observational discovery. However, sufficiently and appropriately coarse-grained sets of alternative histories have standard probabilities providing information about the real fine-grained history that can be compared with observation. We recover the probabilities of decoherent histories quantum mechanics for sets of histories that are recorded and therefore decohere. Quantum mechanics can be viewed as a classical stochastic theory of histories with extended probabilities and a well-defined notion of reality common to all decoherent sets of alternative coarse-grained histories.

We study the amounts of fine-tuning of the parameters of the MSSM with non-universal soft supersymmetry-breaking contributions to the Higgs masses (the NUHM) that would be required for the relic neutralino density to lie within the range favoured by WMAP and other astrophysical and cosmological observations. Such dark matter fine-tuning is analogous to the commonly studied electroweak fine-tuning associated with satisfying the electroweak symmetry breaking conditions, which we also study for completeness.

Combustion characterization of the blend of plant coal and recovered coal fines. Technical report, December 1, 1991--February 29, 1992  

SciTech Connect

The overall objective of this proposed research program is to determine the combustion characteristics of the blend derived from mixing a plant coal and recovered and clean coal fines from the pond. During this study, one plant coal and three blend samples will be prepared and utilized. The blend samples will be of a mixture of 90% plant coal + 10% fines, 85% plant coal + 15% fines, 80% plant coal + 20% fines having particle size distribution of 70% passing through -200 mesh size. These samples` combustion behavior will be examined in two different furnaces at Penn State University, i.e., a down-fired furnace and a drop-tube furnace. The down-fired furnace will be used mainly to measure the emissions and ash deposition study, while the drop tube furnace will be used to determine burning profile, combustion efficiency, etc.

Arasteh, and Christian Kohler Call Number LBNL-1133E Abstract This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m2K), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC.

Demonstration of LED Retrofit Lamps at the Jordan Schnitzer Museum of Art  

SciTech Connect

The Jordan Schnitzer Museum of Art in Eugene, Oregon, houses a remarkable permanent collection of Asian art and antiquities, modern art, and sculpture, and also hosts traveling exhibitions. In the winter and spring of 2011, a series of digital photographs by artist Chris Jordan, titled "Running the Numbers," was exhibited in the Coeta and Donald Barker Special Exhibitions Gallery. These works graphically illustrate waste (energy, money, health, consumer objects, etc.) in contemporary culture. The Bonneville Power Administration and the Eugene Water and Electricity Board provided a set of Cree 12W light-emitting diode (LED) PAR38 replacement lamps (Cree LRP38) for the museum to test for accent lighting in lieu of their standard Sylvania 90W PAR38 130V Narrow Flood lamps (which draw 78.9W at 120V). At the same time, the museum tested LED replacement lamps from three other manufacturers, and chose the Cree lamp as the most versatile and most appropriate color product for this exhibit. The lamps were installed for the opening of the show in January 2011. This report describes the process for the demonstration, the energy and economic results, and results of a survey of the museum staff and gallery visitors on four similar clusters of art lighted separately by four PAR38 lamps.

Development of an Ultra-fine Coal Dewatering Technology and an Integrated Flotation-Dewatering System for Coal Preparation Plants  

SciTech Connect

The project proposal was approved for only the phase I period. The goal for this Phase I project was to develop an industrial model that can perform continuous and efficient dewatering of fine coal slurries of the previous flotation process to fine coal cake of {approx}15% water content from 50-70%. The feasibility of this model should be demonstrated experimentally using a lab scale setup. The Phase I project was originally for one year, from May 2005 to May 2006. With DOE approval, the project was extended to Dec. 2006 without additional cost from DOE to accomplish the work. Water has been used in mining for a number of purposes such as a carrier, washing liquid, dust-catching media, fire-retardation media, temperature-control media, and solvent. When coal is cleaned in wet-processing circuits, waste streams containing water, fine coal, and noncombustible particles (ash-forming minerals) are produced. In many coal preparation plants, the fine waste stream is fed into a series of selection processes where fine coal particles are recovered from the mixture to form diluted coal fine slurries. A dewatering process is then needed to reduce the water content to about 15%-20% so that the product is marketable. However, in the dewatering process currently used in coal preparation plants, coal fines smaller than 45 micrometers are lost, and in many other plants, coal fines up to 100 micrometers are also wasted. These not-recovered coal fines are mixed with water and mineral particles of the similar particle size range and discharged to impoundment. The wasted water from coal preparation plants containing unrecoverable coal fine and mineral particles are called tailings. With time the amount of wastewater accumulates occupying vast land space while it appears as threat to the environment. This project developed a special extruder and demonstrated its application in solid-liquid separation of coal slurry, tailings containing coal fines mostly less than 50 micron. The extruder is special because all of its auger surface and the internal barrier surface are covered with the membranes allowing water to drain and solid particles retained. It is believed that there are four mechanisms working together in the dewatering process. They are hydrophilic diffusion flow, pressure flow, agitation and air purging. Hydrophilic diffusion flow is effective with hydrophilic membrane. Pressure flow is due to the difference of hydraulic pressure between the two sides of the membrane. Agitation is provided by the rotation of the auger. Purging is achieved with the air blow from the near bottom of the extruder, which is in vertical direction.

Effect of coarse or fine grinding on utilization of dry or ensiled corn by lactating dairy cows  

E-Print Network (OSTI)

This study evaluated the effect of coarse or fine grinding of three forms of corn on the performance of lactating cows. Six diets, fed as total mixed rations, were identical except for the corn portion of the diet. Corn treatments were dry shelled corn, high moisture ensiled ear corn, and high moisture ensiled shelled corn, either coarsely or finely ground. The experimental design was a6 × 6 Latin square with 36 cows. Eighteen cows were assigned to the six different treatments and were fed once daily. Within this group of 18 cows, six had a ruminal cannula and were used to evaluate nutrient digestibilities and ruminal fermentation. The remaining 18 cows, six of which were ruminally cannulated, were similarly assigned, except they were fed twice daily. In the group fed once daily, milk production and composition were not affected by treatment. Starch digestibility was greater with the high moisture and with the finely ground corn treatments. In addition, the high moisture ensiled corn treatments had reduced ruminal ammonia concentrations. In the group that was fed twice daily, milk production and protein yield were greatest for the finely ground high moisture ensiled shelled corn treatment. Starch utilization was improved by fine grinding. Lower ruminal ammonia concentrations were obtained with the high moisture ensiled corn treatments, and there was a tendency for reduced ammonia concentration with fine grinding. Results indicate that high moisture ensiled corn as well as fine grinding improved nitrogen and starch utilization.

The LIFE Laser Design in Context: A Comparison to the State-of-the-Art  

Science Conference Proceedings (OSTI)

The current point design for the LIFE laser leverages decades of solid-state laser development in order to achieve the performance and attributes required for inertial fusion energy. This document provides a brief comparison of the LIFE laser point design to other state-of-the-art solid-state lasers. Table I compares the attributes of the current LIFE laser point design to other systems. the state-of-the-art for single-shot performance at fusion-relevant beamline energies is exemplified by performance observed on the National Ignition Facility. The state-of-the-art for high average power is exemplified by the Northrup Grumman JHPSSL laser. Several items in Table I deal with the laser efficiency; a more detailed discussion of efficiency can be found in reference 5. The electrical-to-optical efficiency of the LIFE design exceeds that of reference 4 due to the availability of higher efficiency laser diode pumps (70% vs. {approx}50% used in reference 4). LIFE diode pumps are discussed in greater detail in reference 6. The 'beam steering' state of the art is represented by the deflection device that will be used in the LIFE laser, not a laser system. Inspection of Table I shows that most LIFE laser attributes have already been experimentally demonstrated. The two cases where the LIFE design is somewhat better than prior experimental work do not involve the development of new concepts: beamline power is increased simply by increasing aperture (as demonstrated by the power/aperture comparison in Table I), and efficiency increases are achieved by employing state-of-the-art diode pumps. In conclusion, the attributes anticipated for the LIFE laser are consistent with the demonstrated performance of existing solid-state lasers.

Production of a pellet fuel from Illinois coal fines. Technical report, March 1--May 31, 1995  

SciTech Connect

The primary goal of this research is to produce a pellet fuel from low-sulfur Illinois coal fines which could burn with emissions of less than 1.8 lbs SO{sub 2}/10{sup 6} Btu in stoker-fired boilers. The significance of 1.8 lbs SO{sub 2}/10{sup 6} Btu is that in the Chicago (9 counties) and St. Louis (2 counties) metropolitan areas, industrial users of coal currently must comply with this level of emissions. For this effort, we will be investigating the use of fines from two Illinois mines which currently mine relatively low-sulfur reserves and that discard their fines fraction (minus 100 mesh). The research will involve investigation of multiple unit operations including column flotation, filtration and pellet production. The end result of the effort will allow for an evaluation of the commercial viability of the approach. Previously it has been decided that corn starch would be used as binder and a roller-and-die mill would be used for pellet manufacture. A quality starch binder has been identified and tested. To potentially lower binder costs, a starch that costs about 50% of the high quality starch was tested. Results indicate that the lower cost starch will not lower binder cost because more is required to produce a comparable quality pellet. Also, a petroleum in water emulsion was evaluated as a potential binder. The compound seemed to have adhesive properties but was found to be a poor binder. Arrangements have been made to collect a waste slurry from the mine previously described.

Changes in the fine structure of stochastic distributions as a consequence of space-time fluctuations  

E-Print Network (OSTI)

Earlier we showed that the fine structure of the spectrum of amplitude variations in the results of measurements of the processes of different nature (in other words, the fine structure of the dispersion of results or the pattern of the corresponding histograms) is subject to macroscopic fluctuations, changing regularly with time. These changes indicate that the dispersion of results that remains after all artifacts are excluded inevitably accompanies any measurements and reflects very basic features of our world. In our research, we have come to the conclusion that this dispersion of results is the effect of space-time fluctuations, which, in their turn, are caused by the movement of the measured object in an anisotropic gravitational field. Among other things, this conclusion means that the examination of the detailed pattern of distributions obtained from the results of measurement of the dynamics of processes of different nature discovers laws, which cannot be revealed with traditional methods for the analysis of time series. These assertions are based on the results of long-term experimental investigations conducted for many decades. The major part of these results, starting with 1958, is published in Russian. The goal of this paper is to give a brief review of those results and provide corresponding references. The most general conclusion of our research is the evidence that the fine structure of stochastic distributions is not accidental. In other words, noncasual is the pattern of histograms plotted from a rather small number of the results of measurement of the dynamics of processes of different nature, from the biochemical reactions and noise in the gravitational antenna to the alpha-decay.

Fine-grid calculations for stellar electron and positron capture rates on Fe isotopes  

SciTech Connect

The acquisition of precise and reliable nuclear data is a prerequisite to success for stellar evolution and nucleosynthesis studies. Core-collapse simulators find it challenging to generate an explosion from the collapse of the core of massive stars. It is believed that a better understanding of the microphysics of core-collapse can lead to successful results. The weak interaction processes are able to trigger the collapse and control the lepton-to-baryon ratio (Y{sub e}) of the corematerial. It is suggested that the temporal variation of Y{sub e} within the core of a massive star has a pivotal role to play in the stellar evolution and a fine-tuning of this parameter at various stages of presupernova evolution is the key to generate an explosion. During the presupernova evolution of massive stars, isotopes of iron, mainly {sup 54-56}Fe, are considered to be key players in controlling Y{sub e} ratio via electron capture on these nuclides. Recently an improved microscopic calculation of weak-interaction-mediated rates for iron isotopes was introduced using the proton-neutron quasiparticle random-phase-approximation (pn-QRPA) theory. The pn-QRPA theory allows a microscopic state-by-state calculation of stellar capture rates which greatly increases the reliability of calculated rates. The results were suggestive of some fine-tuning of the Y{sub e} ratio during various phases of stellar evolution. Here we present for the first time the fine-grid calculation of the electron and positron capture rates on {sup 54-56}Fe. The sensitivity of the pn-QRPA calculated capture rates to the deformation parameter is also studied in this work. Core-collapse simulators may find this calculation suitable for interpolation purposes and for necessary incorporation in the stellar evolution codes.

Integration of stripping of fines slurry in a coking and gasification process  

DOE Patents (OSTI)

In an integrated fluid coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a wet scrubbing process and wherein the resulting solids-liquid slurry is stripped to remove acidic gases, the stripped vapors of the stripping zone are sent to the gas cleanup stage of the gasification product gas. The improved stripping integration is particularly useful in the combination coal liquefaction process, fluid coking of bottoms of the coal liquefaction zone and gasification of the product coke.

Gas-Mediated Impact Dynamics in Fine-Grained Granular Materials  

E-Print Network (OSTI)

Non-cohesive granular media exhibit complex responses to sudden impact that often differ from those of ordinary solids and liquids. We investigate how this response is mediated by the presence of interstitial gas between the grains. Using high-speed x-ray radiography we track the motion of a steel sphere through the interior of a bed of fine, loose granular material. We find a crossover from nearly incompressible, fluid-like behavior at atmospheric pressure to a highly compressible, dissipative response once most of the gas is evacuated. We discuss these results in light of recent proposals for the drag force in granular media.

DY/DZ from fine structure in the Main Sequence based on Hipparcos parallaxes  

E-Print Network (OSTI)

The slope Delta Y/Delta Z is a quantity of interest in relation to stellar evolution, the initial mass function and the determination of the primordial helium abundance. In this paper we estimate Delta Y/Delta Z from fine structure in the Main Sequence of nearby stars from Hipparcos data for stars with Z \\leq Zsun and find a value of about 3, which is consistent with what has been found in extragalactic H II regions and with stellar models for suitable upper limits to the initial masses of supernovae according to the IMF slope adopted.

Solar abundances and helioseismology: fine structure spacings and separation ratios of low-degree p modes  

E-Print Network (OSTI)

We have used 4752 days of data collected by the Birmingham Solar-Oscillations Network (BiSON) to determine very precise oscillation frequencies of acoustic low-degree modes that probe the solar core. We compare the fine (small frequency) spacings and frequency separation ratios formed from these data with those of different solar models. We find that models constructed with low metallicity are incompatible with the observations. The results provide strong support for lowering the theoretical uncertainties on the neutrino fluxes. These uncertainties had recently been raised due to the controversy over the solar abundances.

SENSOR FOR INDIVIDUAL BURNER CONTROL OF FIRING RATE, FUEL-AIR RATIO, AND COAL FINENESS CORRELATION  

SciTech Connect

To minimize program cost, additional testing is planned to be performed in concert with EPRI-funded testing at the Coal Flow Test Facility in late July. This will be followed by field testing to be performed by EPRI in August. The minimal effort put into the analysis during this reporting period revealed surprising variation in the trends of the dynamic signatures over time. It is unclear whether these temporal trends are related to noise or to the actual dynamics. Further data analysis and fine-tuning of the algorithm will be done upon arrival of the data to be collected in the near future.

Development of an advanced process for drying fine coal in an inclined fluidized bed  

SciTech Connect

The objective of this research project was to demonstrate a technically feasible and economically viable process for drying and stabilizing high-moisture subbituminous coal. Controlled thermal drying of coal fines was achieved using the inclined fluidized-bed drying and stabilization process developed by the Western Research Institute. The project scope of work required completion of five tasks: (1) project planning, (2) characterization of two feed coals, (3) bench-scale inclined fluidized-bed drying studies, (4) product characterization and testing, and (5) technical and economic evaluation of the process. High moisture subbituminous coals from AMAX Eagle Butte mine located in the Powder River Basin of Wyoming and from Usibelli Coal Mine, Inc. in Healy, Alaska were tested in a 10-lb/hr bench-scale inclined fluidized-bed. Experimental results show that the dried coal contains less than 1.5% moisture and has a heating value over 11,500 Btu/lb. The coal fines entrainment can be kept below 15 wt % of the feed. The equilibrium moisture of dried coal was less than 50% of feed coal equilibrium moisture. 7 refs., 60 figs., 47 tabs.

Evaluation of fine-particle size catalysts using bituminous and subbituminous coals  

SciTech Connect

The objectives of Sandia`s fine-particle size catalyst testing project are to evaluate and compare the activities of fine-particle size catalysts being developed in DOE/PETC`s Advanced Research Coal Liquefaction Program by using Sandia`s standard coal liquefaction test procedures. The first test procedure uses bituminous coal (DECS-17 Blind Canyon coal), phenanthrene as the reaction solvent, and a factorial experimental design that is used to evaluate catalysts over ranges of temperature, time, and catalyst loading. The best catalyst evaluated to date is West Virginia University`s iron catalyst that was impregnated onto the coal. Current work is aimed at developing a standard test procedure using subbituminous Wyodak coal. Ibis test is being developed using Pacific Northwest Laboratories` 6-line ferrihydrite catalyst and coal samples impregnated with either molybdenum or iron at Argonne National Laboratories. Results of testing catalysts with bituminous coal will be summarized and the development of the subbituminous coal test procedure will be presented.

Optimizing Fine-grained Communication in a Biomolecular Simulation Application on Cray XK6  

Science Conference Proceedings (OSTI)

Achieving good scaling for fine-grained communication intensive applications on modern supercomputers remains challenging. In our previous work, we have shown that such an application NAMD scales well on the full Jaguar XT5 without long-range interactions; Yet, with them, the speedup falters beyond 64K cores. Although the new Gemini interconnect on Cray XK6 has improved network performance, the challenges remain, and are likely to remain for other such networks as well. We analyze communication bottlenecks in NAMD and its CHARM++ runtime, using the Projections performance analysis tool. Based on the analysis, we optimize the runtime, built on the uGNI library for Gemini. We present several techniques to improve the fine-grained communication. Consequently, the performance of running 92224-atom Apoa1 with GPUs on TitanDev is improved by 36%. For 100-million-atom STMV, we improve upon the prior Jaguar XT5 result of 26 ms/step to 13 ms/step using 298,992 cores on Jaguar XK6.

NLE Websites -- All DOE Office Websites (Extended Search)

Standardizing the Art of Electron-Beam Welding. Standardizing the Art of Electron-Beam Welding. WELDED materials are an integral part of everyday life. Appliances, cars, and bridges are all made by welding materials together. But not all welds are created equal. Welding methods vary in complexity, time, and cost, depending on a product's requirements and purpose. In electron-beam (EBeam) welding, an electron beam generated in a vacuum creates a fusing heat source that can unite almost any metals. This method produces deep welds without adding excessive heat that can adversely affect the properties of the surrounding metal. In the nuclear energy and aerospace industries, electron-beam welding is preferred for manufacturing high-value welds-those in which defects cannot be tolerated.

Improvement of storage, handling, and transportability of fine coal. Quarterly technical progress report number 8, October 1--December 31, 1995  

SciTech Connect

The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. On the other hand, Mulled Coal does not cause the fugitive and airborne dust problems normally associated with thermally dried coal. The objectives of this project are to demonstrate that: the Mulled Coal process, which has been proved to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality, and at a convincing rate of production in a commercial coal preparation plant; the wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation; and a wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems.

Combustion characterization of the blend of plant coal and recovered coal fines. Technical report, September 1--November 30, 1991  

SciTech Connect

The overall objective of this proposed research program is to determine the combustion characteristics of the blend derived from mixing a plant coal and recovered and clean coal fines from the pond. During this study, one plant coal and three blend samples will be prepared and utilized. The blend samples will be of a mixture of 90% plant coal + 10% fines, 85% plant coal + 15% fines, 80% plant coal + 20% fines having particle size distribution of 70% passing through {minus}200 mesh size. These samples` combustion behavior will be examined in two different furnaces at Penn State University, i.e., a down-fired furnace and a drop-tube furnace. The down-fired furnace will be used mainly to measure the emissions and ash deposition study, while the drop tube furnace will be used to determine burning profile, combustion efficiency, etc. This report covers the first quarter`s progress. Major activities during this period were focused on finding the plants where a demo MTU column will be installed to prepare the samples needed to characterize the combustion behavior of slurry effluents. Also, a meeting was held at Penn State University to discuss the availability of the laboratory furnace for testing the plant coal/recovered coal fines blends.

Nontoxic chemical process for in situ permeability enhancement and accelerated decontamination of fine-grain subsurface sediments  

DOE Patents (OSTI)

The remediation of heterogeneous subsurfaces is extremely time consuming and expensive with current and developing technologies. Although such technologies can adequately remove contaminants in the high hydraulic conductivity, coarse-grained sediments, they cannot access the contaminated low hydraulic conductivity fine-grained sediments. The slow bleed of contaminants from the fine-grained sediments is the primary reason why subsurface remediation is so time-consuming and expensive. This invention addresses the problem of remediating contaminated fine-grained sediments. It is intended that, in the future, a heterogeneous site be treated by a hybrid process that first remediates the high hydraulic conductivity, coarse-grained sediments, to be followed by the process, described in this invention, to treat the contaminated low hydraulic conductivity fine-grained sediments. The invention uses cationic flocculants and organic solvents to collapse the swelling negative double layer surrounding water saturated clay particles, causing a flocculated, cracked clay structure. The modification of the clay fabric in fine-grained sediments dramatically increases the hydraulic conductivity of previously very tight clays many orders of magnitude. 8 figs.

Human error and general aviation accidents: A comprehensive, fine-grained analysis using HFACS  

E-Print Network (OSTI)

The Human Factors Analysis and Classification System (HFACS) is a theoretically based tool for investigating and analyzing human error associated with accidents and incidents. Previous research performed at both at the University of Illinois and the Civil Aerospace Medical Institute (CAMI) have been highly successful and have shown that HFACS can be reliably used to analyze the underlying human causes of both commercial and general aviation (GA) accidents. these analyses have helped identify general trends in the types of human factors issues and aircrew errors that have contributed to civil aviation accidents. The next step is to identify the exact nature of the human errors identified. The purpose of this research effort, therefore, was to address these questions by performing a fine-grained HFACS analysis of the individual human causal factors associated with GA accidents and to assist in the generation of intervention programs. This report details those findings and offers an approach for developing interventions to address them.

A fine-focusing x-ray source using carbon-nanofiber field emitter  

Science Conference Proceedings (OSTI)

A fine-focusing x-ray source has been constructed employing a field electron emitter prepared by growing carbon-nanofibers (CNFs) on a metal tip. The x-ray source is composed of a CNF field electron emitter, an electrostatic lens, two magnetic lenses, and a W-target for generating x-rays by electron impact. The CNFs provided field electrons with a current density of J{approx}5x10{sup 9} A/m{sup 2}, which was evaluated with the aid of Fowler-Nordheim theory. The electron beam extracted from the CNF emitter was accelerated to the energies of E=10-25 keV, and then focused by the lenses. By recording the x-ray images of test charts, the optimum resolution of the x-ray source was estimated to be approximately D{sub x}=0.5 {mu}m.

LiFePO{sub 4} is a potential candidate for the cathode material of the lithium secondary batteries. A co-precipitation method was adopted to prepare LiFePO{sub 4} because it is simple and cheap. Nitrogen gas was needed to prevent oxidation of Fe{sup 2+} in the aqueous solution. The co-precipitated precursor shows the high reactivity with the reductive gas, and the single phase of LiFePO{sub 4} is successfully synthesized with the aid of carbon under less reductive conditions. LiFePO{sub 4} fine powder prepared by co-precipitation method shows high rate capability, impressive specific capacity and cycle property.

Chiral Symmetry Restoration, Naturalness and the Absence of Fine-Tuning I: Global Theories  

E-Print Network (OSTI)

The Standard Model (SM), and the scalar sector of its zero-gauge-coupling limit -- the chiral-symmetric limit of the Gell Mann-Levy Model (GML) -- have been shown not to suffer from a Higgs Fine-Tuning (FT) problem. All ultraviolet quadratic divergences (UVQD) are absorbed into the mass-squared of pseudo Nambu-Goldstone (pNGB) bosons, in GML. Since chiral SU(2)_{L-R} symmetry is restored as the pNGB mass-squared or as the Higgs vacuum expectation value (VEV) are taken to 0, small values of these quantities and of the Higgs mass are natural, and therefore not Fine-Tuned. In this letter, we extend our results on the absence of FT to a wide class of high-mass-scale (M_{Heavy}>>m_{Higgs}) extensions to a simplified SO(2) version of GML. We explicitly demonstrate naturalness and no-FT for two examples of heavy physics, both SO(2) singlets: a heavy (M_S >> m_{Higgs}) real scalar field (with or without a VEV); and a right-handed Type 1 See-Saw Majorana neutrino with M_R >> m_{Higgs}. We prove that for |q^2| energy effective theory with certain high-mass-scale extensions. We conjecture that, since gravity couples democratically to particles, quantum gravitational theories that respect chiral symmetry will also retain naturalness, and avoid FT problems for GML and the SM. Phenomenological consequences include the renewed possibility of thermal lepto-genesis in the neutrino-MSM. Absent a FT problem, there should be no expectation that LHC will discover physics beyond the SM unrelated to neutrino mixing.

Fatigue and Creep-Fatigue Deformation of an Ultra-Fine Precipitate Strengthened Advanced Austenitic Alloy  

SciTech Connect

An advanced austenitic alloy, HT-UPS (high-temperature ultrafine-precipitation-strengthened), has been identified as an ideal candidate material for the structural components of fast reactors and energy-conversion systems. HT-UPS alloys demonstrate improved creep resistance relative to 316 stainless steel (SS) through additions of Ti and Nb, which precipitate to form a widespread dispersion of stable nanoscale metallic carbide (MC) particles in the austenitic matrix. The low-cycle fatigue and creep-fatigue behavior of an HT-UPS alloy have been investigated at 650 °C and a 1.0% total strain, with an R-ratio of -1 and hold times at peak tensile strain as long as 150 min. The cyclic deformation response of HT-UPS is directly compared to that of standard 316 SS. The measured values for total cycles to failure are similar, despite differences in peak stress profiles and in qualitative observations of the deformed microstructures. Crack propagation is primarily transgranular in fatigue and creep-fatigue of both alloys at the investigated conditions. Internal grain boundary damage in the form of fine cracks resulting from the tensile hold is present for hold times of 60 min and longer, and substantially more internal cracks are quantifiable in 316 SS than in HT-UPS. The dislocation substructures observed in the deformed material differ significantly; an equiaxed cellular structure is observed in 316 SS, whereas in HT-UPS the microstructure takes the form of widespread and relatively homogenous tangles of dislocations pinned by the nanoscale MC precipitates. The significant effect of the fine distribution of precipitates on observed fatigue and creep-fatigue response is described in three distinct behavioral regions as it evolves with continued cycling.

Architectural characteristics of fine-grained submarine fans: A model applicable to the Gulf of Mexico  

Science Conference Proceedings (OSTI)

Submarine fan deposits in the Gulf of Mexico, modern and ancient, fall in the category of fine-grained, low overall sand/shale ratio basin-floor fans. Models published over the years that have been applied to both exploration and production are based on sand-rich fans, most of which were deposited in active margin settings. These models should not be used for the Gulf of Mexico or any other deep water system with similar basinal settings. Observations from the excellent outcrops of the Permian Tanqua Karoo in southwestern South Africa, together with information from the modern Mississippi Fan, and the Jackfork turbidites in Arkansas, enable the construction of a model that addresses the architecture of both the macro and meso-scale depositional features of fine-grained turbidite systems. At the entrance to the basin floor the conduit, carved out across the slope, may start to widen. Most of the density flows moving through do not necessarily occupy the conduit`s entire width. The result is a complex of laterally and vertically stacked channel fills and associated levee-overbank deposits with a good degree of connectivity. The channel fills are mostly massive, whereas the levee deposits are low-contrast, low-resistivity thin-bedded sandstones and shales with high permeability. Such sandstones can be potentially very productive. The channels gradually become smaller and as their influence on directing the heads of turbidity currents decreases, oblong sheet sands are deposited, each having a very large width to thickness ratio and a high sand/shale ratio. The vertical stacking patterns within these sheet sands commonly display lateral offset of individual beds or groups of beds, and therefore form a distinct reservoir type with varying internal fluid-flow characteristics.

Sorption of organic carbon compounds to the fine fraction of surface and Subsurface Soils  

Science Conference Proceedings (OSTI)

Dissolved organic carbon (DOC) transported from the soil surface is stabilized in deeper soil profiles by physicochemical sorption processes. However, it is unclear how different forms of organic carbon (OC) compounds common in soil organic matter interact with soil minerals in the surface (A) and subsurface (B) horizons. We added four compounds (glucose, starch, cinnamic acid and stearic acid) to the silt- and clay-sized fraction (fine fraction) of A and B horizons of eight soils from varying climates (3 temperate, 3 tropical, 1 arctic and 1 sub-arctic). Equilibriumbatch experiments were conducted using 0 to 100 mg C L 1 of 14C-labeled compounds for 8 h. Sorption parameters (maximum sorption capacity, Qmax and binding coefficient, k) calculated by fitting sorption data to the Langmuir equation showed that Qmax of A and B horizons was very similar for all compounds. Both Qmax and k values were related to sorbate properties, with Qmax being lowest for glucose (20 500 mg kg 1), highest for stearic acid (20,000 200,000 mg kg 1), and intermediate for both cinnamic acid (200 4000 mg kg 1) and starch (400 6000 mg kg 1). Simple linear regression analysis revealed that physicochemical properties of the sorbents influenced the Qmax of cinnamic acid and stearic acid, but not glucose and starch. The sorbent properties did not show predictive ability for binding coefficient k. By using the fine fraction as sorbent, we found that the mineral fractions of A horizons are equally reactive as the B horizons irrespective of soil organic carbon content.

Resistance spot welding of ultra-fine grained steel sheets produced by constrained groove pressing: Optimization and characterization  

Science Conference Proceedings (OSTI)

Constrained groove pressing as a severe plastic deformation method is utilized to produce ultra-fine grained low carbon steel sheets. The ultra-fine grained sheets are joined via resistance spot welding process and the characteristics of spot welds are investigated. Resistance spot welding process is optimized for welding of the sheets with different severe deformations and their results are compared with those of as-received samples. The effects of failure mode and expulsion on the performance of ultra-fine grained sheet spot welds have been investigated in the present paper and the welding current and time of resistance spot welding process according to these subjects are optimized. Failure mode and failure load obtained in tensile-shear test, microhardness, X-ray diffraction, transmission electron microscope and scanning electron microscope images have been used to describe the performance of spot welds. The region between interfacial to pullout mode transition and expulsion limit is defined as the optimum welding condition. The results show that optimum welding parameters (welding current and welding time) for ultra-fine grained sheets are shifted to lower values with respect to those for as-received specimens. In ultra-fine grained sheets, one new region is formed named recrystallized zone in addition to fusion zone, heat affected zone and base metal. It is shown that microstructures of different zones in ultra-fine grained sheets are finer than those of as-received sheets. - Highlights: Black-Right-Pointing-Pointer Resistance spot welding process is optimized for joining of UFG steel sheets. Black-Right-Pointing-Pointer Optimum welding current and time are decreased with increasing the CGP pass number. Black-Right-Pointing-Pointer Microhardness at BM, HAZ, FZ and recrystallized zone is enhanced due to CGP.

ENGINEERING DEVELOPMENT OF ADVANCED PHYSICAL FINE COAL CLEANING FOR PREMIUM FUEL APPLICATIONS  

SciTech Connect

Bechtel, together with Amax Research and Development Center (Amax R&D), has prepared this study which provides conceptual cost estimates for the production of premium quality coal-water slurry fuel (CWF) in a commercial plant. Two scenarios are presented, one using column flotation technology and the other the selective agglomeration to clean the coal to the required quality specifications. This study forms part of US Department of Energy program ?Engineering Development of Advanced Physical Fine Coal Cleaning for Premium Fuel Applications,? (Contract No. DE-AC22- 92PC92208), under Task 11, Project Final Report. The primary objective of the Department of Energy program is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to stable and highly loaded CWF. The fuels should contain less than 2 lb ash/MBtu (860 grams ash/GJ) of HHV and preferably less than 1 lb ash/MBtu (430 grams ash/GJ). The advanced fine coal cleaning technologies to be employed are advanced column froth flotation and selective agglomeration. It is further stipulated that operating conditions during the advanced cleaning process should recover not less than 80 percent of the carbon content (heating value) in the run-of-mine source coal. These goals for ultra-clean coal quality are to be met under the constraint that annualized coal production costs does not exceed $2.5 /MBtu ($ 2.37/GJ), including the mine mouth cost of the raw coal. A further objective of the program is to determine the distribution of a selected suite of eleven toxic trace elements between product CWF and the refuse stream of the cleaning processes. Laboratory, bench-scale and Process Development Unit (PDU) tests to evaluate advanced column flotation and selective agglomeration were completed earlier under this program with selected coal samples. A PDU with a capacity of 2 st/h was designed by Bechtel and installed at Amax R&D, Golden, Colorado by Entech Global for process evaluation tests. The tests successfully demonstrated the capability of advanced column flotation as well as selective agglomeration to produce ultra-clean coal at specified levels of purity and recovery efficiency. Test results and the experience gained during the operation of the PDU have provided valuable insights into the processes studied. Based on the design data obtained from the test work and a set of project design criteria, two sets of conceptual designs for commercial CWF production plants have been developed, one using column flotation and the other using selective agglomeration process. Using these designs, Capital as well as Operating and Maintenance (O&M) cost estimates for the plants have been compiled. These estimates have then been used to derive the annualized cost of production of premium CWF on a commercial scale. Further, a series of sensitivity analysis have been completed to evaluate the effects of variations in selected cost components and process parameters on the overall economics of premium fuel production

A LOW COST AND HIGH QUALITY SOLID FUEL FROM BIOMASS AND COAL FINES  

SciTech Connect

Use of biomass wastes as fuels in existing boilers would reduce greenhouse gas emissions, SO2 and NOx emissions, while beneficially utilizing wastes. However, the use of biomass has been limited by its low energy content and density, high moisture content, inconsistent configuration and decay characteristics. If biomass is upgraded by conventional methods, the cost of the fuel becomes prohibitive. Altex has identified a process, called the Altex Fuel Pellet (AFP) process, that utilizes a mixture of biomass wastes, including municipal biosolids, and some coal fines, to produce a strong, high energy content, good burning and weather resistant fuel pellet, that is lower in cost than coal. This cost benefit is primarily derived from fees that are collected for accepting municipal biosolids. Besides low cost, the process is also flexible and can incorporate several biomass materials of interest The work reported on herein showed the technical and economic feasibility of the AFP process. Low-cost sawdust wood waste and light fractions of municipal wastes were selected as key biomass wastes to be combined with biosolids and coal fines to produce AFP pellets. The process combines steps of dewatering, pellet extrusion, drying and weatherizing. Prior to pilot-scale tests, bench-scale test equipment was used to produce limited quantities of pellets for characterization. These tests showed which pellet formulations had a high potential. Pilot-scale tests then showed that extremely robust pellets could be produced that have high energy content, good density and adequate weatherability. It was concluded that these pellets could be handled, stored and transported using equipment similar to that used for coal. Tests showed that AFP pellets have a high combustion rate when burned in a stoker type systems. While NOx emissions under stoker type firing conditions was high, a simple air staging approach reduced emissions to below that for coal. In pulverized-fuel-fired tests it was found that the ground pellets could be used as an effective NOx control agent for pulverized-coal-fired systems. NOx emissions reductions up to 63% were recorded, when using AFP as a NOx control agent. In addition to performance benefits, economic analyses showed the good economic benefits of AFP fuel. Using equipment manufacturer inputs, and reasonable values for biomass, biosolids and coal fines costs, it was determined that an AFP plant would have good profitability. For cases where biosolids contents were in the range of 50%, the after tax Internal Rates of Return were in the range of 40% to 50%. These are very attractive returns. Besides the baseline analysis for the various AFP formulations tested at pilot scale, sensitivity analysis showed the impact of important parameters on return. From results, it was clear that returns are excellent for a range of parameters that could be expected in practice. Importantly, these good returns are achieved even without incentives related to the emissions control benefits of biomass.

POC-SCALE TESTING OF A DRY TRIBOELECTROSTATIC SEPARATOR FOR FINE COAL CLEANING  

SciTech Connect

Numerous advanced coal cleaning processes have been developed in recent years that are capable of substantially reducing both ash- and sulfur-forming minerals from coal. However, most of the processes involve fine grinding and use water as the cleaning medium; therefore, the clean coal products must be dewatered before they can be transported and burned. Unfortunately, dewatering fine coal is costly, which makes it difficult to deploy advanced coal cleaning processes for commercial applications. As a means of avoiding problems associated with the fine coal dewatering, the National Energy Technology Laboratory (NETL) developed a dry coal cleaning process in which mineral matter is separated from coal without using water. In this process, pulverized coal is subjected to triboelectrification before being placed in an electric field for electrostatic separation. The triboelectrification is accomplished by passing a pulverized coal through an in-line mixer made of copper. Copper has a work function that lies between that of carbonaceous material (coal) and mineral matter. Thus, coal particles impinging on the copper wall lose electrons to the metal thereby acquiring positive charges, while mineral matter impinging on the wall gain electrons to acquire negative charges. The charged particles then pass through an electric field where they are separated according to their charges into two or more products depending on the configuration of the separator. The results obtained at NETL showed that it is capable of removing more than 90% of the pyritic sulfur and 70% of the ash-forming minerals from a number of eastern U.S. coals. However, the BTU recoveries were less than desirable. The laboratory-scale batch triboelectrostatic separator (TES) used by NETL relied on adhering charged particles on parallel electrode surfaces and scraping them off. Therefore, its throughput will be proportional to the electrode surface area. If this laboratory device is scaled-up as is, it would suffer from low throughput capacities and high maintenance requirements. In general, surface area-based separators (e.g., shaking tables, magnetic drum separator, electrodynamic separator, etc.) have lower throughput capacities than volume-based separators (e.g., flotation cell, dense-medium bath, cyclones, etc.) by an order of magnitude. Furthermore, the electrodes of the laboratory unit need to be cleaned frequently, creating a high maintenance requirement if it is scaled-up to a commercial unit. The bench-scale continuous TES unit developed at NETL, on the other hand, separates positively and negatively charged particles by splitting the gaseous stream containing these particles in an electric field by means of a flow splitter, so that the oppositely charged particles can be directed into different compartments. This device is fundamentally different from the laboratory unit in that the former is a surface area-based separator, while the latter is a volume-based separator. The bench-scale unit is referred to as an entrained flow separator by the in-house researchers at NETL. Thus, the entrained flow TES unit is a significant improvement over the laboratory unit with regard to throughput capacity. In the present work, the entrained flow separator concept will be utilized for developing a proof-of concept (POC) separator that can be scaled-up to commercial size units. To accomplish this, it is necessary to develop a bench-scale separator that can achieve high Btu recoveries while maintaining the high degree of separation efficiencies. It is the objective of the present investigation to develop an efficient separator by studying the mechanisms of triboelectrification and investigating better ways of separating the charged particles. An important criterion for developing efficient separators is that they not only provide high separation efficiencies but also have high throughput capacities, which are essential ingredients for successful commercialization.

Arasteh, Howdy Goudey, and Robert Hart Journal Solar Energy Materials and Solar Cells Volume 96 Start Page 1 Pagination 1-28 Date Published 01/2012 Keywords Fenestration, Low-e, Multilayer glazing, Smart window, Solar cell glazing, Vacuum glazing Abstract Fenestration of today is continuously being developed into the fenestration of tomorrow, hence offering a steadily increase of daylight and solar energy utilization and control, and at the same time providing a necessary climate screen with a satisfactory thermal comfort. Within this work a state of the art market review of the best performing fenestration products has been carried out, along with an overview of possible future research opportunities for the fenestration industry. The focus of the market review was low thermal transmittance (U-value). The lowest centre of glass Ug-values found was 0.28 W/(m2K) and 0.30 W/(m2K), which was from a suspended coating glazing product and an aerogel glazing product, respectively. However, the majority of high performance products found were triple glazed. The lowest frame U-value was 0.61 W/(m2K). Vacuum glazing, smart windows, solar cell glazing, window frames, self cleaning glazing, low-emissivity coatings and spacers were also reviewed, thus also representing possibilities for controlling and harvesting the solar radiation energy. Currently, vacuum glazing, new spacer materials and solutions, electrochromic windows and aerogel glazing seem to have the largest potential for improving the thermal performance and daylight and solar properties in fenestration products. Aerogel glazing has the lowest potential U-values, ~ 0.1 W/(m2K), but requires further work to improve the visible transmittance. Electrochromic vaccum glazing and evacuated aerogel glazing are two vacuum related solutions which have a large potential. There may also be opportunities for completely new material innovations which could revolutionize the fenestration industry.

Wind-turbine siting: a summary of the state of the art  

DOE Green Energy (OSTI)

The process of siting large wind turbines may be divided into two broad steps: site selection, and site evaluation. Site selection is the process of locating windy sites where wind energy development shows promise of economic viability. Site evaluation is the process of determining in detail for a given site the economic potential of the site. This paper emphasizes the state of the art in the first aspect of siting, site selection. Several techniques for assessing the wind resource have been explored or developed in the Federal Wind Energy Program. Local topography and meteorology will determine which of the tehniques should be used in locating potential sites.

The key to creating a ZNEH is to minimize the size of costly PV systems by maximizing the energy efficiency of the home and its end-use equipment. The focus here is on single-family houses, the residential segment for which most ZNEH research an...

Evaluation of ceramic filters for high-temperature/high-pressure fine particulate control. Final report Dec 75-Jun 76  

SciTech Connect

High temperature gas turbines used to generate electric power require gas streams virtually free of particulate matter. Gas streams from high temperature, high pressure coal processes, such as low Btu gasification and pressurized fluidized bed combustion, require considerable particulate removal. In order to maintain high thermal efficiency the particulate clean-up must be done at the high temperatures of the process. Many new concepts for fine particulate control at elevated temperatures are presently being proposed. One such concept utilizes ceramic membrane filters. The report gives results of a study to analyze and evaluate ceramic membrane filters as a new, fine particulate (<3 um) control concept for high-temperature (approx. 900/sup 0/C), high-pressure processes. Several ceramic filters were identified as potential candidates for fine particulate removal. There does not seem to be any inherent material limitation to high-temperature operation; however, no evidence of high-temperature filter application was found. The filters typically are 2-6 mm thick, cylindrical, and available with various pore sizes, increasing upward from 0.5 um. These elements may be suitable for fine particulate control in hot gas streams. The most promising, although undeveloped, idea for a ceramic filter is to use ceramic honeycomb monoliths similar to those available for catalyst supports and heat exchangers. The walls of the monoliths are about 0.2-0.4 mm thick and of varying pore size and porosity. Geometric configurations are available which would force the gas to flow through the membrane walls. Pressure losses would be very small relative to those of standard ceramic filter elements. The application of ceramic monoliths to high-temperature fine particulate control appears very promising. It is strongly recommended that this concept be investigated further.

MROrchestrator: A Fine-Grained Resource Orchestration Framework for MapReduce Clusters  

Science Conference Proceedings (OSTI)

Efficient resource management in data centers and clouds running large distributed data processing frameworks like MapReduce is crucial for enhancing the performance of hosted applications and boosting resource utilization. However, existing resource scheduling schemes in Hadoop MapReduce allocate resources at the granularity of fixed-size, static portions of nodes, called slots. In this work, we show that MapReduce jobs have widely varying demands for multiple resources, making the static and fixed-size slot-level resource allocation a poor choice both from the performance and resource utilization standpoints. Furthermore, lack of co-ordination in the management of mul- tiple resources across nodes prevents dynamic slot reconfigura- tion, and leads to resource contention. Motivated by this, we propose MROrchestrator, a MapReduce resource Orchestrator framework, which can dynamically identify resource bottlenecks, and resolve them through fine-grained, co-ordinated, and on- demand resource allocations. We have implemented MROrches- trator on two 24-node native and virtualized Hadoop clusters. Experimental results with a suite of representative MapReduce benchmarks demonstrate up to 38% reduction in job completion times, and up to 25% increase in resource utilization. We further show how popular resource managers like NGM and Mesos when augmented with MROrchestrator can hike up their performance.

Image-Directed Fine-needle Aspiration Biopsy of the Thyroid with Safety-engineered Devices  

SciTech Connect

Purpose: The purpose of the present study was to integrate safety-engineered devices into outpatient fine-needle aspiration (FNA) biopsy of the thyroid in an interventional radiology practice. Materials and Methods: The practice center is a tertiary referral center for image-directed FNA thyroid biopsies in difficult patients referred by the primary care physician, endocrinologist, or otolaryngologist. As a departmental quality of care and safety improvement program, we instituted integration of safety devices into our thyroid biopsy procedures and determined the effect on outcome (procedural pain, diagnostic biopsies, inadequate samples, complications, needlesticks to operator, and physician satisfaction) before institution of safety devices (54 patients) and after institution of safety device implementation (56 patients). Safety devices included a patient safety technology-the mechanical aspirating syringe (reciprocating procedure device), and a health care worker safety technology (antineedlestick safety needle). Results: FNA of thyroid could be readily performed with the safety devices. Safety-engineered devices resulted in a 49% reduction in procedural pain scores (P < 0.0001), a 56% reduction in significant pain (P < 0.002), a 21% increase in operator satisfaction (P < 0.0001), and a 5% increase in diagnostic specimens (P = 0.5). No needlesticks to health care workers or patient injuries occurred during the study. Conclusions: Safety-engineered devices to improve both patient and health care worker safety can be successfully integrated into diagnostic FNA of the thyroid while maintaining outcomes and improving safety.

High-Throughput Asynchronous Pipelines for Fine-Grain Dynamic Datapaths  

E-Print Network (OSTI)

This paper introduces several new asynchronous pipeline designs which offer high throughput as well as low latency. The designs target dynamic datapaths, both dualrail as well as single-rail. The new pipelines are latchfree and therefore are particularly well-suited for fine-grain pipelining, i.e., where each pipeline stage is only a single gate deep. The pipelines employ new control structures and protocols aimed at reducing the handshaking delay, the principal impediment to achieving high throughput in asynchronous pipelines. As a test vehicle, a 4-bit FIFO was designed using 0.6 micron technology. The results of careful HSPICE simulations of the FIFO designs are very encouraging. The dualrail designs deliver a throughput of up to 860 million data items per second. This performance represents an improvement by a factor of 2 over a widely-used comparable approach by Williams [16]. The new single-rail designs deliver a throughput of up to 1208 million data items per second.

Fine structure collision strengths and line ratios for [Ne V] in infrared and optical sources  

E-Print Network (OSTI)

Improved collisions strengths for the mid-infrared and optical transitions in Ne V are presented. Breit-Pauli R-Matrix calculations for electron impact excitation are carried out with fully resolved near-threshold resonances at very low energies. In particular, the fine structure lines at 14 micron and 24 micron due to transitions among the ground state levels 1s^22s^22p^3 (^3P_{0,1,2}), and the optical/near-UV lines at 2973, 3346 and 3426 Angstrom transitions among the ^3P_{0,1,2}, ^1D_2, ^1S_0 levels are described. Maxwellian averaged collision strengths are tabulated for all forbidden transistion within the ground configuration. Significant differences are found in the low temperature range Te < 10000 K for both the FIR and the opitcal transitions compared to previous results. An analysis of the 14/24 line ratio in low-energy-density (LED) plasma conditions reveals considerable variation; the effective rate coefficient may be dominated by the very low-energy behaviour rather than the maxwellian averaged...

Fine topological structure of coherent complex light created by carbon nanocomposites in LC  

E-Print Network (OSTI)

Fine complex light structure, optical singularities and electroconductivty of nematic 5CB doped by multi-walled carbon nanotubes (MWCNTs) were investigated. MWCNTs gather spontaneously to system of micro scale clusters with random fractal borders at small enough concentration. They are surrounded by the striped micro scale cladding which creates optical singularities in propagating laser beam. Applied transverse electric field above the Freedericksz initiates homeotropic arrangement of 5CB and the striped inversion walls between nanotubes clusters what diminishes free energy of a composite. Theory of their appearance and properties was built. Simultaneously the striped cladding disappears what can be treated as new mechanism of structure orientation nonlinearity in nonlinear photonics. Polarization singularities (circular C points) were measured firstly. Percolation of clusters enhances strongly electrical conductivity of the system and creates inversion walls even without applied field. Carbon nanotubes composites in LC form bridge between nano dopants and micro/macro system and are promising for applications. Elaborated protocol of singular optics inspection and characterization of LC nanocomposites is promising tool for applications in modern nanosience and technique.

Evaluation of fine-particle size catalysts using standard test procedures  

SciTech Connect

The goal of this project is to evaluate and compare the activities/selectivities of fine-particle size catalysts being developed in the DOE/PETC Advanced Research (AR) Liquefaction Program by using standard coal liquefaction activity test procedures. Since bituminous and subbituminous coals have significantly different properties, it is feasible that catalysts may perform differently with these coal types. Because all previous testing has been done with the DECS-17 Blind Canyon bituminous coal, it is important to develop the capability of evaluating catalysts using a subbituminous coal. Initial efforts towards developing a subbituminous coal test are aimed at comparing the reactivities of the Wyodak subbituminous coal and the Blind Canyon bituminous coal. Therefore, the same factorial experimental design was used with the Wyodak coal as was used previously with the Blind Canyon coal. In addition, PNL`s 6-line ferrihydrite catalyst precursor was used in the development of the Wyodak coal test procedure because this catalyst is the best powder catalyst found to date in Sandia`s tests with Blind Canyon coal. Results show that Blind Canyon coal yields higher DHP amounts in the reaction products and higher tetrahydrofuran conversions at the higher severity conditions. Wyodak coal gives higher heptane conversions and higher gas yields for all conditions tested.

X-ray absorption fine structure spectroscopic study of uranium nitrides  

Science Conference Proceedings (OSTI)

Uranium mononitride (UN), sesquinitride (U2N3) and dinitride (UN2) were characterized by extended X-Ray absorption fine structure spectroscopy. Analysis on UN indicate the presence of three uranium shells at distances of 3.46(3), 4.89(5) and 6.01(6) A and a nitrogen shell at a distance of 2.46(2) A . For U2N3, two absorbing uranium atoms at different crystallographic positions are present in the structure. One of the uranium atoms is surrounded by nitrogen atoms at 2.28(2) A and by uranium atoms at 3.66(4) and 3.95(4) A . The second type of uranium atom is surrounded by nitrogen atoms at 2.33(2) and 2.64(3) A and by uranium atoms at 3.66(4), 3.95(4) and 5.31(5) A . Results on UN2 indicate two uranium shells at 3.71(4) and 5.32(5) A and two nitrogen shells at 2.28(2).

Use of a vegetative filter zone to control fine-grained sediments from surface mines  

Science Conference Proceedings (OSTI)

The objective of this study was to demonstrate the effectiveness of a vegetative filter zone in trapping fine-grained sediments from surface mining operations. The area selected for study was located in Whitley County, Kentucky, directly below an active surface mining operation. The outslope above the filter was the primary drainage area monitored during the study. This project was initiated with the specific purpose of conducting a field test on vegetation as a viable sediment trapping medium. From the onset, the project was wholly designed for a field evaluation under typical mining conditions. The filter area was constructed directly below an abandoned surface mine bench, on typical soil types found in mined areas of Eastern Kentucky. The outslope located above the filter was the primary source area for sediment flow. Sediment-laden water samples were collected at the inlet flume for comparison with samples collected at the outlet flume to permit evaluation of the sediment removal capability of the vegetative filter. Results of the monitoring efforts revealed that a dramatic reduction in sediment load was achieved by vegetative filtration with trapping efficiencies ranging from 70 to 99% for the storms monitored. Based on results of this study, it is concluded that vegetative filters are an effective method for reducing the quantity of sediment transported into surface streams and rivers from disturbed mined lands.

Microstructure, Morphology, and Nanomechanical Properties Near Fine Holes Produced by Electro-Discharge Machining  

Science Conference Proceedings (OSTI)

Fine holes in metal alloys are employed for many important technological purposes, including cooling and the precise atomization of liquids. For example, they play an important role in the metering and delivery of fuel to the combustion chambers in energy-efficient, low-emissions diesel engines. Electro-discharge machining (EDM) is one process employed to produce such holes. Since the hole shape and bore morphology can affect fluid flow, and holes also represent structural discontinuities in the tips of the spray nozzles, it is important to understand the microstructures adjacent to these holes, the features of the hole walls, and the nanomechanical properties of the material that was in some manner altered by the EDM hole-making process. Several techniques were used to characterize the structure and properties of spray-holes in a commercial injector nozzle. These include scanning electron microscopy, cross-sectioning and metallographic etching, bore surface roughness measurements by optical interferometry, scanning electron microscopy, and transmission electron microscopy of recast EDM layers extracted with the help of a focused ion beam.

Fabrication and thermoelectric properties of fine-grained TiNiSn compounds  

Science Conference Proceedings (OSTI)

Nearly single-phased TiNiSn half-Heusler compound thermoelectric materials were synthesized by combining mechanical alloying (MA) and spark plasma sintering (SPS) in order to reduce its thermal conductivity by refining the grain sizes. Although TiNiSn compound powders were not synthesized directly via MA, dense bulk samples of TiNiSn compound were obtained by the subsequent SPS treatment. It was found that an excessive Ti addition relative to the TiNiSn stoichiometry is effective in increasing the phase purity of TiNiSn half-Heusler phase in the bulk samples, by compensating for the Ti loss caused by the oxidation of Ti powders and MA processing. The maximum power factor value obtained in the Ti-compensated sample is 1720 muW m{sup -1} K{sup -2} at 685 K. A relatively high ZT value of 0.32 is achieved at 785 K for the present undoped TiNiSn compound polycrystals. - Graphical abstract: Nearly single-phased TiNiSn-based half-Heusler compound polycrystalline materials with fine grains were fabricated by combining mechanical alloying (MA) and spark plasma sintering (SPS). A high ZT value for undoped TiNiSn was obtained because of the reduced thermal conductivity.

ART CCIM Phase II-A Off-Gas System Evaluation Test Plan  

Science Conference Proceedings (OSTI)

This test plan defines testing to be performed using the Idaho National Laboratory (INL) engineering-scale cold crucible induction melter (CCIM) test system for Phase II-A of the Advanced Remediation Technologies (ART) CCIM Project. The multi-phase ART-CCIM Project is developing a conceptual design for replacing the joule-heated melter (JHM) used to treat high level waste (HLW) in the Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) with a cold crucible induction melter. The INL CCIM test system includes all feed, melter off-gas control, and process control subsystems needed for fully integrated operation and testing. Testing will include operation of the melter system while feeding a non-radioactive slurry mixture prepared to simulate the same type of waste feed presently being processed in the DWPF. Process monitoring and sample collection and analysis will be used to characterize the off-gas composition and properties, and to show the fate of feed constituents, to provide data that shows how the CCIM retrofit conceptual design can operate with the existing DWPF off-gas control system.

A study on the human ability to detect soot deposition onto works of art  

SciTech Connect

Works of art can become soiled due to the deposition of airborne black soot particles within museums and art galleries. The soot particle deposition rates are already known for many environments, but knowing the levels of carbon particle coverage at which humans can detect image darkening is also important. Therefore, in this work, human subjects have been tested to determine their ability to detect soiling by black carbon particles deposited onto specially prepared samples having colored backgrounds. The results show that certain observers are able to detect that a sample is becoming soiled once surface coverage by black carbon particles has reached 2.4% if the soiled samples and clean samples are placed directly adjacent to each other, producing a sharp dividing line (an ``edge-to-edge'' comparison). Observers can detect the presence of soiling with greater than 90% accuracy during an edge-to-edge comparison on most backgrounds when soiling levels reach approximately 3.6% surface coverage by black particles. If the comparison between soiled and clean samples must be made with samples that are separated from each other by a neutral gray area, soiling is only detected with 100% accuracy once coverage by black particles has reached 12.0% surface coverage. These results show that a greater accumulation of black carbon than was previously thought is required to produce a visibly soiled surface.

AN INTRIGUING CHROMOSPHERIC JET OBSERVED BY HINODE: FINE STRUCTURE KINEMATICS AND EVIDENCE OF UNWINDING TWISTS  

SciTech Connect

We report a chromospheric jet lasting for more than 1 hr observed by the Hinode Solar Optical Telescope in unprecedented detail. The ejection occurred in three episodes separated by 12-14 minutes, with the amount and velocity of material decreasing with time. The upward velocities range from 438 to 33 km s{sup -1}, while the downward velocities of the material falling back have smaller values (mean: -56km s{sup -1}) and a narrower distribution (standard deviation: 14km s{sup -1}). The average acceleration inferred from parabolic spacetime tracks is 141 m s{sup -2}, a fraction of the solar gravitational acceleration. The jet consists of fine threads (0.''5-2'' wide), which exhibit coherent, oscillatory transverse motions perpendicular to the jet axis and about a common equilibrium position. These motions propagate upward along the jet, with the maximum phase speed of 744+-11 km s{sup -1}at the leading front of the jet. The transverse oscillation velocities range from 151 to 26 km s{sup -1}, amplitudes from 6.0 to 1.9 Mm, and periods from 250 to 536 s. The oscillations slow down with time and cease when the material starts to fall back. The falling material travels along almost straight lines in the original direction of ascent, showing no transverse motions. These observations are consistent with the scenario that the jet involves untwisting helical threads, which rotate about the axis of a single large cylinder and shed magnetic helicity into the upper atmosphere.

Pyrite surface characterization and control for advanced fine coal desulfurization technologies  

SciTech Connect

The objective of this project is to conduct extensive studies on the surface reactivity and surface hydrophobicity of coal-pyrites using various surface characterization techniques and to correlate the alteration of the coal-pyrite surface with the efficiency of pyrite rejection in coal flotation. The flotation characteristics of coal-pyrites under various conditions was studied and compared with ore-pyrite and coal to determine the causes of pyrite rejection difficulties in coal flotation. Both the native and induced floatabilities of pyrites were investigated. It was found that both coal- and ore-pyrites, ff prepared by dry-grinding, show little or no floatability in the absence of any chemical reagents. After ultrasonic pretreatment, ore-pyrite floats effectively in the acidic to neutral pH range. Kentucky No. 9 coal-pyrite (KYPY) shows significant flotation in the pH range 7--10. With ethyl xanthate as collector, ore-pyrite floats well up to pH = 10; while coal-pyrite reveals no flotation above pH = 6. For the first time, the effect of coal collector on the floatability of coal-pyrite has been studied. It was shown that in the presence of fuel oil--a widely used collector for promoting coal flotation, coal-pyrite, particularly for the fine sizes, shows good flotation below pH = 11, whereas ore-pyrite has no or little floatability. These studies demonstrate that one of the main causes of the coal-pyrite flotation in coal separation is the oil-induced floatability due to adsorption/attachment of oil droplets on the coal-pyrite surfaces, the native'' or self-induced'' floatability of pyrite is no as profound as the oil-induced flotation.

Hubble Space Telescope Fine Guidance Sensor Parallaxes of Galactic Cepheid Variable Stars: Period-Luminosity Relations  

E-Print Network (OSTI)

(abridged) We present new absolute trigonometric parallaxes and relative proper motions for nine Galactic Cepheid variable stars: l Car, zeta Gem, beta Dor, W Sgr, X Sgr, Y Sgr, FF Aql, T Vul, and RT Aur. We obtain these results with astrometric data from Fine Guidance Sensor 1r, a white-light interferometer on Hubble Space Telescope. We find absolute parallaxes with an average sigma_pi/pi = 8%. Two stars (FF Aql and W Sgr) required the inclusion of binary astrometric perturbations, providing Cepheid mass estimates. With these parallaxes we compute absolute magnitudes in V, I, K, and Wesenheit W_{VI} bandpasses corrected for interstellar extinction and Lutz-Kelker-Hanson bias. Adding our previous absolute magnitude determination for delta Cep, we construct Period-Luminosity relations for ten Galactic Cepheids. We compare our new Period-Luminosity relations with those adopted by several recent investigations, including the Freedman and Sandage H_0 projects. Adopting our Period-Luminosity relationship would tend to increase the Sandage H_$ value, but leave the Freedman H_0 unchanged. Comparing our Galactic Cepheid PLR with those derived from LMC Cepheids, we find the slopes for K and W_{VI} identical in the two galaxies within their respective errors. Our data lead to a W_{VI} distance modulus for the Large Magellanic Cloud, m-M = 18.50\\pm0.03, uncorrected for any metallicity effects. Applying recently derived metalllcity corrections yields a corrected LMC distance modulus of (m-M)_0=18.40\\pm0.05. Comparing our Period-Luminosity relationship to solar-metallicity Cepheids in NGC 4258 results in a distance modulus, 29.28 \\pm 0.08, which agrees with that derived from maser studies.

Pilot scale single stage fine coal dewatering and briquetting process. Technical report, September 1--November 30, 1995  

SciTech Connect

The primary goal of the current coal preparation research is to reduce the ash and sulfur content from coal, using fine grinding and various coal cleaning processes to separate finely disseminated mineral matter and pyrite from coal. Small coal particles are produced by the grinding operation, thus the ultrafine coal becomes very difficult to dewater. In addition, the ultrafine coal also creates problems during its transportation, storage and handling at utility plants. The current research is seeking to combine ultrafine coal dewatering and briquetting processes into a single stage operation, using hydrophobic binders as coal dewatering and binding reagents with the help of a compaction device. From previous tests, it has been found that coal pellets with a moisture content of less than 15% and good wear and water resistance can be successfully fabricated at pressures of less than 6,000 psi using a lab scale ram extruder. The primary objective of the research described in this quarter has been to extend the lab scale ultrafine coal dewatering and briquetting process into a pilot scale operation, based on the test data obtained from earlier research. A standard roller briquetting machine was used to dewater fine coal-binder mixtures during the briquetting process. The operating parameters, including moisture content of feed, feed rate, and roller speed, were evaluated on the basis of the performance of the briquettes. Briquettes fabricated at rates of up to 108 pellets per minute exhibited satisfactory water and wear resistance, i.e., less than 7.5% cured moisture and less than 8.3% weight loss after 6 min. of tumbling. Also, coal-binder samples with moisture contents of 40 percent have been successfully dewatered and briquetted. Briquetting of fine coal was possible under current feeding conditions, however, a better feeding system must be designed to further improve the quality of dewatered coal briquettes.

State of the art review of radioactive waste volume reduction techniques for commercial nuclear power plants  

Science Conference Proceedings (OSTI)

A review is made of the state of the art of volume reduction techniques for low level liquid and solid radioactive wastes produced as a result of: (1) operation of commercial nuclear power plants, (2) storage of spent fuel in away-from-reactor facilities, and (3) decontamination/decommissioning of commercial nuclear power plants. The types of wastes and their chemical, physical, and radiological characteristics are identified. Methods used by industry for processing radioactive wastes are reviewed and compared to the new techniques for processing and reducing the volume of radioactive wastes. A detailed system description and report on operating experiences follow for each of the new volume reduction techniques. In addition, descriptions of volume reduction methods presently under development are provided. The Appendix records data collected during site surveys of vendor facilities and operating power plants. A Bibliography is provided for each of the various volume reduction techniques discussed in the report.

A General Simulation Framework for Supply Chain Modeling: State of the Art and Case Study  

E-Print Network (OSTI)

Nowadays there is a large availability of discrete event simulation software that can be easily used in different domains: from industry to supply chain, from healthcare to business management, from training to complex systems design. Simulation engines of commercial discrete event simulation software use specific rules and logics for simulation time and events management. Difficulties and limitations come up when commercial discrete event simulation software are used for modeling complex real world-systems (i.e. supply chains, industrial plants). The objective of this paper is twofold: first a state of the art on commercial discrete event simulation software and an overview on discrete event simulation models development by using general purpose programming languages are presented; then a Supply Chain Order Performance Simulator (SCOPS, developed in C++) for investigating the inventory management problem along the supply chain under different supply chain scenarios is proposed to readers.

Color, the Visual Arts, and Representations of Otherness in the Victorian Novel  

E-Print Network (OSTI)

This dissertation investigates the cultural connections made between race and color in works of fiction from the Victorian and Edwardian era, particularly how authors who are also artists invent fantastically colored characters who are purple, blue, red, and yellow to rewrite (and sometimes reclaim) difference in their fiction. These strange and eccentric characters include the purple madwoman in Charlotte Brontë’s Jane Eyre (1847), the blue gentleman from Wilkie Collins’s Poor Miss Finch (1872), the red peddler in Thomas Hardy’s The Return of the Native (1878), and the little yellow girls of Arthur Conan Doyle’s “The Yellow Face” (1893) and Frances Hodgson Burnett’s The Secret Garden (1911). These fictional texts serve as a point of access into the cultural meanings of color in the nineteenth century and are situated at the intersection of Victorian discourses on the visual arts and race science. The second half of the nineteenth century constitutes a significant moment in the history of color: the rapid development of new color technologies helps to trigger the upheavals of the first avant-garde artistic movements and a reassessment of coloring’s prestige in the art academies. At the same time, race science appropriates color, using it as a criterion for classification in the establishment of global racial hierarchies. By imagining what it would be like to change one’s skin color, these artist-authors employ the aesthetic realm of color to explore the nature of human difference and alterity. In doing so, some of them are able to successfully formulate their own challenges to nineteenth-century racial discourse.

SOURCE SIGNATURES OF FINE PARTICULATE MATTER FROM PETROLEUM REFINING AND FUEL USE  

DOE Green Energy (OSTI)

The molecular structure and microstructure of a suite of fine particulate matter (PM) samples produced by the combustion of residual fuel oil and diesel fuel were investigated by an array of analytical techniques. Some of the more important results are summarized below. Diesel PM (DPM): A small diesel engine test facility was used to generate a suite of diesel PM samples from different fuels under engine load and idle conditions. C XANES, {sup 13}C NMR, XRD, and TGA were in accord that the samples produced under engine load conditions contained more graphitic material than those produced under idle conditions, which contained a larger amount of unburned diesel fuel and lubricating oil. The difference was enhanced by the addition of 5% of oxygenated compounds to the reference fuel. Scanning transmission x-ray micro-spectroscopy (STXM) was able to distinguish particulate regions rich in C=C bonds from regions rich in C-H bonds with a resolution of {approx}50 nm. The former are representative of more graphitic regions and the latter of regions rich in unburned fuel and oil. The dominant microstructure observed by SEM and TEM consisted of complex chain-like structures of PM globules {approx}20-100 nm in mean diameter, with a high fractal dimension. High resolution TEM revealed that the graphitic part of the diesel soot consisted of onion-like structures made up of graphene layers. Typically 3-10 graphene layers make up the ''onion rings'', with the layer spacing decreasing as the number of layers increases. ROFA PM: Residual oil fly ash (ROFA) PM has been analyzed by a new approach that combines XAFS spectroscopy with selective leaching procedures. ROFA PM{sub 2.5} and PM{sub 2.5+} produced in combustion facilities at the U.S. EPA National Risk Management Research Laboratory (NRML) were analyzed by XAFS before and after leaching with water, acid (1N HCl), and pentane. Both water and acid leaching removed most of the metal sulfates, which were the dominant phase present for most metals (V, Ni, Zn, etc.). This allowed conclusive identification in the leaching residue of important secondary sulfide and oxide phases, including Ni sulfide, a toxic and carcinogenic phase observed in the leached PM{sub 2.5+} samples. Other significant secondary phases identified included V{sub 2}O{sub 4}, V sulfide, and NiFe{sub 2}O{sub 4}.

Characterization of Fine Particulate Matter (PM) and Secondary PM Precursor Gases in the Mexico City Metropolitan Area  

SciTech Connect

This project was one of three collaborating grants funded by DOE/ASP to characterize the fine particulate matter (PM) and secondary PM precursors in the Mexico City Metropolitan Area (MCMA) during the MILAGRO Campaign. The overall effort of MCMA-2006, one of the four components, focused on i) examination of the primary emissions of fine particles and precursor gases leading to photochemical production of atmospheric oxidants and secondary aerosol particles; ii) measurement and analysis of secondary oxidants and secondary fine PM production, with particular emphasis on secondary organic aerosol (SOA), and iii) evaluation of the photochemical and meteorological processes characteristic of the Mexico City Basin. The collaborative teams pursued the goals through three main tasks: i) analyses of fine PM and secondary PM precursor gaseous species data taken during the MCMA-2002/2003 campaigns and preparation of publications; ii) planning of the MILAGRO Campaign and deployment of the instrument around the MCMA; and iii) analysis of MCMA-2006 data and publication preparation. The measurement phase of the MILAGRO Campaign was successfully completed in March 2006 with excellent participation from the international scientific community and outstanding cooperation from the Mexican government agencies and institutions. The project reported here was led by the Massachusetts Institute of Technology/Molina Center for Energy and the Environment (MIT/MCE2) team and coordinated with DOE/ASP-funded collaborators at Aerodyne Research Inc., University of Colorado at Boulder and Montana State University. Currently 24 papers documenting the findings from this project have been published. The results from the project have improved significantly our understanding of the meteorological and photochemical processes contributing to the formation of ozone, secondary aerosols and other pollutants. Key findings from the MCMA-2003 include a vastly improved speciated emissions inventory from on-road vehicles: the MCMA motor vehicles produce abundant amounts of primary PM, elemental carbon, particle-bound polycyclic aromatic hydrocarbons, carbon monoxide and a wide range of air toxics; the feasibility of using eddy covariance techniques to measure fluxes of volatile organic compounds in an urban core and a valuable tool for validating local emissions inventory; a much better understanding of the sources and atmospheric loadings of volatile organic compounds; the first spectroscopic detection of glyoxal in the atmosphere; a unique analysis of the high fraction of ambient formaldehyde from primary emission sources; characterization of ozone formation and its sensitivity to VOCs and NOx; a much more extensive knowledge of the composition, size distribution and atmospheric mass loadings of both primary and secondary fine PM, including the fact that the rate of MCMA SOA production greatly exceeded that predicted by current atmospheric models; evaluations of significant errors that can arise from standard air quality monitors for O3 and NO2; and the implementation of an innovative Markov Chain Monte Carlo method for inorganic aerosol modeling as a powerful tool to analyze aerosol data and predict gas phase concentrations where these are unavailable. During the MILAGRO Campaign the collaborative team utilized a combination of central fixed sites and a mobile laboratory deployed throughout the MCMA to representative urban and boundary sites to measure trace gases and fine particles. Analysis of the extensive 2006 data sets has confirmed the key findings from MCMA-2002/2003; additionally MCMA-2006 provided more detailed gas and aerosol chemistry and wider regional scale coverage. Key results include an updated 2006 emissions inventory; extension of the flux system to measure fluxes of fine particles; better understanding of the sources and apportionment of aerosols, including contribution from biomass burning and industrial sources; a comprehensive evaluation of metal containing particles in a complex urban environment; identification of a close correlation between

Bioconversion of Secondary Fiber Fines to Ethanol Using Counter-Current Enzymatic Saccharification and Co-Fermentation  

E-Print Network (OSTI)

This research examined several enzymatic and microbial process for the conversion of waste cellulosic fibers into ethanol. The first was a one-stage process in which pulp fines were contacted with commercial enzyme solutions. The second process used sequential, multistage saccharification. The third used sequential enzyme addition in a countercurrent mode. Experiments compared the results with various feedstocks, different commercial enzymes, supplementation with b-glucosidase, and saccharification combined with fermentation. The highest saccharification (65%) from a 4% consistency pulp and the highest sugar concentration (5.4%) from an 8% consistency pulp were attained when 5 FPU/g plus 10 IU/g of b-glucosidase were used.

Performance Characteristics of an Electrochemically Powered Turboprop: A Comparison with State of the Art Gas Turbines  

E-Print Network (OSTI)

As we search for alternative fuels and energy efficient vehicles it is important to consider the role of electrochemical fuel cells in aircraft propulsion systems. This paper focuses on this issue with regards to small turboprop aircraft. An electrochemical propulsion system would employ liquid hydrogen in an air breathing fuel cell that would generate electricity to run electric motors which in tum power the props. The major question this paper addresses is: under what conditions will a hydrogen/fuel cell power system be superior to a state of the art hydrogen/gas turbine power system? The systems are compared on a fuel consumption basis, a cost basis, and a reliability/ maintainability basis. The analysis show that both specific power and efficiency play an important role in determining which configuration uses less fuel. In general, the fuel cell system is heavier but more efficient than the gas turbine. It appears that the fuel cell system will begin to compete with the gas turbine as the power densities surpass 1 kw/kg and the efficiencies approaches .45. From a cost perspective gas turbines presently cost $500/ Kw and fuel cells are far more expensive. However, the raw materials in a fuel cell are inexpensive and could conceivably be cheaper, thus making the fuel cells increasingly attractive. From a reliability perspective, the fuel cell system appears to have a significant advantage due to the lack of moving parts and the high reliability of electric motors.

Intermediate Photovoltaic System Application Experiment. Oklahoma Center for Science and Arts. Phase II. Final report  

DOE Green Energy (OSTI)

This report presents the key results of the Phase II efforts for the Intermediate PV System Applications Experiment at the Oklahoma Center for Science and Arts (OCSA). This phase of the project involved fabrication, installation and integration of a nominal 140 kW flat panel PV system made up of large, square polycrystalline-silicon solar cell modules, each nominally 61 cm x 122 cm in size. The output of the PV modules, supplied by Solarex Corporation, was augmented, 1.35 to 1 at peak, by a row of glass reflectors, appropriately tilted northward. The PV system interfaces with the Oklahoma Gas and Electric Utility at the OCSA main switchgear. Any excess power generated by the system is fed into the utility under a one to one buyback arrangement. Except for a shortfall in the system output, presently suspected to be due to the poor performance of the modules, no serious problems were encountered. Certain value engineering changes implemented during construction and early operational failure events associated with the power conditioning system are also described. The system is currently undergoing extended testing and evaluation.

State-of-the-art hydrogen sulfide control for geothermal energy systems: 1979  

DOE Green Energy (OSTI)

Existing state-of-the-art technologies for removal of hydrogen sulfide are discussed along with a comparative assessment of their efficiencies, reliabilities and costs. Other related topics include the characteristics of vapor-dominated and liquid-dominated resources, energy conversion systems, and the sources of hydrogen sulfide emissions. It is indicated that upstream control technologies are preferred over downsteam technologies primarily because upstream removal of hydrogen sulfide inherently controls all downstream emissions including steam-stacking. Two upstream processes for vapor-dominated resources appear promising; the copper sulfate (EIC) process, and the steam converter (Coury) process combined with an off-gas abatement system such as a Stretford unit. For liquid-dominated systems that produce steam, the process where the non-condensible gases are scrubbed with spent geothermal fluid appears to be promising. An efficient downstream technology is the Stretford process for non-condensible gas removal. In this case, partitioning in the surface condenser will determine the overall abatement efficiency. Recommendations for future environmental control technology programs are included.

Solar energy in Kentucky's homes: the state of the art. [Monograph  

SciTech Connect

Information on the state of the art of residential solar energy use in Kentucky covers basic solar energy terms and concepts and a discussion of the suitability of Kentucky's climate for solar energy use. Climatic comparisons of Kentucky and the rest of the nation show that the amount of sunshine in Kentucky is more than adequate for use in home heating. The second section discusses the financial and legal considerations of whether residential solar energy is economically justified, given the high initial costs. A simulated comparison with gas and electric heating shows solar energy to be economically attractive only when electricity is the alternative fuel. Passive systems, which were not evaluated, however, are very economical. Tax incentives are available at the federal level. The state legislature is considering tax incentives, but has not addressed solar access. A mail survey of homeowners indicates satisfaction among 82% of the 51 solar home owners. Repairs are the major cause of dissatisfaction. The report concludes that now is the time for homeowners to explore alternatives to conventional fuels and, particularly, to consider solar energy. 64 references, 7 figures, 23 tables.

Reclaiming the Ungentlemanly Arts: The Global Origins of SOE and OSS  

E-Print Network (OSTI)

Sir Colin McV. Gubbins, former director of Britain's Special Operations Executive (SOE), explained in 1966 to a Danish audience that it is much easier to pronounce a new organization than to actually create it. This dissertation examines the processes whereby SOE was created, including how its doctrine was formulated and subsequently disseminated, both to its own agents and to its American counterpart, the Office of Strategic Services (OSS). Traditional narratives, which imply that SOE had no precedents, fail to appreciate that Gubbins and his colleagues consciously looked to past and contemporary examples for inspiration. This dissertation follows Gubbins's career, examining his experience of unconventional warfare in the Allied Intervention in Russia, in Ireland during the Irish Revolution, and in India. To personal experience was added the experience of colleagues and the knowledge he gained by study of several other historical and contemporary conflicts. Pragmatically synthesizing this information, Gubbins authored two brief guides in 1939: the Art of Guerilla Warfare and the Partisan Leader's Handbook. In 1940 Gubbins joined the new SOE and was given charge of both operations and training, allowing his ideas to shape SOE's agents and form their thinking. Even before the entry of the United States into the Second World War, OSS turned to Britain for training in intelligence and sabotage. SOE played a substantial role in this process, propagating Gubbins's ideas even further. Although the Americans drew upon their own sources of inspiration as well, SOE and Gubbins's doctrines were significant, arguably central, to American thinking.

Engineering development of advanced physical fine coal cleaning for premium fuel applications: Subtask 3.3 - dewatering studies  

SciTech Connect

If successful, the novel Hydrophobic Dewatering (HD) process being developed in this project will be capable of efficiently removing moisture from fine coal without the expense and other related drawbacks associated with mechanical dewatering or thermal drying. In the HD process, a hydrophobic substance is added to a coal-water slurry to displace water from the surface of coal, while the spent hydrophobic substance is recovered for recycling. For this process to have commercialization potential, the amount of butane lost during the process must be small. Earlier testing revealed the ability of the hydrophobic dewatering process to reduce the moisture content of fine coal to a very low amount as well as the determination of potential butane losses by the adsorption of butane onto the coal surface. Work performed in this quarter showed that the state of oxidation affects the amount of butane adsorbed onto the surface of the coal and also affects the final moisture content. the remaining work will involve a preliminary flowsheet of a continuous bench-scale unit and a review of the economics of the system. 1 tab.

Measurement and capture of fine and ultrafine particles from a pilot-scale pulverized coal combustor with an electrostatic precipitator  

Science Conference Proceedings (OSTI)

Experiments were carried out in a pilot-scale pulverized coal combustor at the Energy and Environmental Research Center (EERC) burning a Powder River Basin (PRB) subbituminous coal. A scanning mobility particle sizer (SMPS) and an electrical low-pressure impactor (ELPI) were used to measure the particle size distributions (PSDs) in the range of 17 nm to 10 m at the inlet and outlet of the electrostatic precipitator (ESP). At the ESP inlet, a high number concentration of ultrafine particles was found, with the peak at approximately 75 nm. A trimodal PSD for mass concentration was observed with the modes at approximately 80-100 nm, 1-2 {mu}m, and 10 {mu}m. The penetration of ultrafine particles through the ESP increased dramatically as particle size decreased below 70 nm, attributable to insufficient or partial charging of the ultrafine particles. Injection of nanostructured fine-particle sorbents for capture of toxic metals in the flue gas caused high penetration of the ultrafine particles through the ESP. The conventional ESP was modified to enhance charging using soft X-ray irradiation. A slipstream of flue gas was introduced from the pilot-scale facility and passed through this modified ESP. Enhancement of particle capture was observed with the soft X-ray irradiation when moderate voltages were used in the ESP, indicating more efficient charging of fine particles. 32 refs., 5 figs., 1 tab.

Coal surface control for advanced physical fine coal cleaning technologies. Final report, September 19, 1988--August 31, 1992  

SciTech Connect

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO{sub 2} emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R&D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

AREVA Federal Services (AFS) is performing a multi-year, multi-phase Advanced Remediation Technologies (ART) project, sponsored by the U.S. Department of Energy (DOE), to evaluate the feasibility and benefits of replacing the existing joule-heated melter (JHM) used to treat high level waste (HLW) in the Defense Waste Processing Facility (DWPF) at the Savannah River Site with a cold crucible induction melter (CCIM). The AFS ART CCIM project includes several collaborators from AREVA subsidiaries, French companies, and DOE national laboratories. The Savannah River National Laboratory and the Commissariat a l’Energie Atomique (CEA) have performed laboratory-scale studies and testing to determine a suitable, high-waste-loading glass matrix. The Idaho National Laboratory (INL) and CEA are performing CCIM demonstrations at two different pilot scales to assess CCIM design and operation for treating SRS sludge wastes that are currently being treated in the DWPF. SGN is performing engineering studies to validate the feasibility of retrofitting CCIM technology into the DWPF Melter Cell. The long-term project plan includes more lab-testing, pilot- and large-scale demonstrations, and engineering activities to be performed during subsequent project phases. A simulant of the DWPF SB4 feed was successfully fed and melted in a small pilot-scale CCIM system during two test series. The OGSE tests provide initial results that (a) provide melter operating conditions while feeding a DWPF SB4 simulant feed, (b) determine the fate of feed organic and metal feed constituents and metals partitioning, and (c) characterize the melter off-gas source term to a downstream off-gas system. The INL CCIM test system was operated continuously for about 30 hours during the parametric test series, and for about 58 hours during the OGSE test. As the DWPF simulant feed was continuously fed to the melter, the glass level gradually increased until a portion of the molten glass was drained from the melter. The glass drain was operated periodically on-demand. A cold cap of unmelted feed was controlled by adjusting the feedrate and melter power levels to obtain the target molten glass temperatures with varying cold cap levels. Three test conditions were performed per the test plan, during which the melter was operated with a target melt temperature of either 1,250oC or 1,300oC, and with either a partial or complete cold cap of unmelted feed on top of the molten glass. Samples of all input and output streams including the starting glass, the simulant feed, the off-gas particulate matter, product glass, and deposits removed from the crucible and off-gas pipe after the test were collected for analysis.

STATE OF THE ART AND FUTURE DEVELOPMENTS IN NATURAL GAS ENGINE TECHNOLOGIES  

DOE Green Energy (OSTI)

Current, state of the art natural gas engines provide the lowest emission commercial technology for use in medium heavy duty vehicles. NOx emission levels are 25 to 50% lower than state of the art diesel engines and PM levels are 90% lower than non-filter equipped diesels. Yet, in common with diesel engines, natural gas engines are challenged to become even cleaner and more efficient to meet environmental and end-user demands. Cummins Westport is developing two streams of technologies to achieve these goals for medium-heavy and heavy-heavy duty applications. For medium-heavy duty applications, lowest possible emissions are sought on SI engines without significant increase in complexity and with improvements in efficiency and BMEP. The selected path builds on the capabilities of the CWI Plus technology and recent diesel engine advances in NOx controls, providing potential to reduce emissions to 2010 values in an accelerated manner and without the use of Selective Catalytic Reduction or NOx Storage and Reduction technology. For heavy-heavy duty applications where high torque and fuel economy are of prime concern, the Westport-Cycle{trademark} technology is in field trial. This technology incorporates High Pressure Direct Injection (HPDI{trademark}) of natural gas with a diesel pilot ignition source. Both fuels are delivered through a single, dual common rail injector. The operating cycle is entirely unthrottled and maintains the high compression ratio of a diesel engine. As a result of burning 95% natural gas rather than diesel fuel, NOx emissions are halved and PM is reduced by around 70%. High levels of EGR can be applied while maintaining high combustion efficiency, resulting in extremely low NOx potential. Some recent studies have indicated that DPF-equipped diesels emit less nanoparticles than some natural gas vehicles [1]. It must be understood that the ultrafine particles emitted from SI natural gas engines are generally accepted to consist predominantly of VOCs [2], and that lubricating oil is a major contributor. Fitting an oxidation catalyst to the natural gas engine leads to a reduction in nanoparticles emissions in comparison to engines without aftertreatment [2,3,4]. In 2001, the Cummins Westport Plus technology was introduced with the C Gas Plus engine, a popular choice for transit bus applications. This incorporates drive by wire, fully integrated, closed loop electronic controls and a standard oxidation catalyst for all applications. The B Gas Plus and the B Propane Plus engines, with application in shuttle and school buses were launched in 2002 and 2003. The gas-specific oxidation catalyst operates in concert with an optimized ring-pack and liner combination to reduce total particulate mass below 0.01g/bhphr, combat ultrafine particles and control VOC emissions.

Composite tube cracking in kraft recovery boilers: A state-of-the-art review  

Science Conference Proceedings (OSTI)

Beginning in the mid-1960s, increasing energy costs in Finland and Sweden made energy recovery more critical to the cost-effective operation of a kraft pulp mill. Boiler designers responded to this need by raising the steam operating pressure, but almost immediately the wall tubes in these new boilers began to corrode rapidly. Test panels installed in the walls of the most severely corroding boiler identified austenitic stainless steel as sufficiently resistant to the new corrosive conditions, and discussions with Sandvik AB, a Swedish tube manufacturer, led to the suggestion that coextruded tubes be used for water wall service in kraft recovery boilers. Replacement of carbon steel by coextruded tubes has solved most of the corrosion problems experienced by carbon steel wall tubes, however, these tubes have not been problem-free. Beginning in early 1995, a multidisciplinary research program funded by the US Department of Energy was established to investigate the cause of cracking in coextruded tubes and to develop improved materials for use in water walls and floors of kraft recovery boilers. One portion of that program, a state-of-the-art review of public- and private-domain documents related to coextruded tube cracking in kraft recovery boilers is reported here. Sources of information that were consulted for this review include the following: tube manufacturers, boiler manufacturers, public-domain literature, companies operating kraft recovery boilers, consultants and failure analysis laboratories, and failure analyses conducted specifically for this project. Much of the information contained in this report involves cracking problems experienced in recovery boiler floors and those aspects of spout and air-port-opening cracking not readily attributable to thermal fatigue. 61 refs.

Design and producing of fine-group cross section library HENDL3.0/FG for subcritical system  

Science Conference Proceedings (OSTI)

To improve the accuracy of the neutron analyses for subcritical system with thermal fission blanket, a coupled neutron and photon (315 n + 42{gamma}) fine-group cross section library HENDL3.0/FG based on ENDF/B-VII, JEFF3.1 and JENDL3.3 was produced by FDS team. In order to test the availability and reliability of the HENDL3.0/FG data library, shielding and critical safety benchmarks were performed with VisualBUS code. The testing results indicated that the discrepancy between calculation and experimental values of nuclear parameters fell in a reasonable range. It showed that the nuclear data library had accuracy and availability. (authors)

Cobra-IE Evaluation by Simulation of the NUPEC BWR Full-Size Fine-Mesh Bundle Test (BFBT)  

Science Conference Proceedings (OSTI)

The COBRA-IE computer code is a thermal-hydraulic subchannel analysis program capable of simulating phenomena present in both PWRs and BWRs. As part of ongoing COBRA-IE assessment efforts, the code has been evaluated against experimental data from the NUPEC BWR Full-Size Fine-Mesh Bundle Tests (BFBT). The BFBT experiments utilized an 8 x 8 rod bundle to simulate BWR operating conditions and power profiles, providing an excellent database for investigation of the capabilities of the code. Benchmarks performed included steady-state and transient void distribution, single-phase and two-phase pressure drop, and steady-state and transient critical power measurements. COBRA-IE effectively captured the trends seen in the experimental data with acceptable prediction error. Future sensitivity studies are planned to investigate the effects of enabling and/or modifying optional code models dealing with void drift, turbulent mixing, rewetting, and CHF.

CT-Guided Percutaneous Fine-Needle Aspiration Biopsy of the Inferior Vena Cava Wall: A Posterior Coaxial Approach  

Science Conference Proceedings (OSTI)

A 72-year-old man was referred to our department with an incidentally diagnosed bronchogenic carcinoma of the right upper lobe. Positron emission tomography (PET) combined with computed tomography (PET-CT) revealed an unexpected hot spot in the ventral wall of the infrarenal segment of the inferior vena cava (IVC). Diagnostic biopsy of this lesion was performed under CT guidance with semiautomated 20G fine-needle aspiration (FNA) through a 19G coaxial needle. Cytology revealed few carcinoma cells, which led to the remarkable diagnosis of a distant metastasis to the IVC wall. Both the immediate postinterventional CT control and the further surveillance period of the patient were unremarkable; in particular, no signs of bleeding complications were detected. We conclude that coaxial FNA of an IVC wall lesion is technically feasible and may even help diagnose distant metastasis.

X-ray absorption fine structure spectroscopic determination of plutonium speciation at the Rocky Flats environmental technology  

SciTech Connect

X-ray Absorption Fine Structure spectroscopy was used to probe the speciation of the ppm level Pu in thirteen soil and concrete samples from the Rocky Flats Environmental Technology Site in support of the site remediation effort that has been successfully completed since these measurements. In addition to X-ray Absorption Near Edge Spectra, two of the samples yielded Extended X-ray Absorption Fine Structure spectra that could be analyzed by curve-fits. Most of these spectra exhibited features consistent with PU(IV), and more specificaJly, PuO{sub 2+x}-type speciation. Two were ambiguous, possibly indicating that Pu that was originally present in a different form was transforming into PuO{sub 2+x}, and one was interpreted as demonstrating the presence of an unusual Pu(VI) compound, consistent with its source being spills from a PUREX purification line onto a concrete floor and the resultant extreme conditions. These experimental results therefore validated models that predicted that insoluble PuO{sub 2+x} would be the most stable form of Pu in equilibrium with air and water even when the source terms were most likely Pu metal with organic compounds or a Pu fire. A corollary of these models' predictions and other in situ observations is therefore that the minimal transport of Pu that occurred on the site was via the resuspension and mobilization of colloidal particles. Under these conditions, the small amounts of diffusely distributed Pu that were left on the site after its remediation pose only a negligible hazard.

Removal of contaminants from fine-grained soils using electrokinetic flushing. Semiannual report, July 1 through December 31, 1992  

SciTech Connect

This report details the status of work conducted on the use of electrokinetics (EK) to remediate a fine grained soil contaminated with lead. The experimental work entails soil collection and characterization, soil adsorption and desorption of lead, and experimental setup construction and testing. Test soil was collected from Northern Erie County, New York and underwent standard preparation and physical/chemical characterization. The soil is a silt loam with a low hydraulic permeability ({approx} 10{sup {minus}7} cm/s), a large amount of fine materials, moderate organic carbon content, and a moderately high cation exchange capacity (CEC). The soil has a low indigenous lead content and is slightly acidic. The soil was artificially contaminated with lead to concentrations of 95, 800, and 7,600 mg Pb/kg soil. Lead desorption experiments were conducted using several concentrations of HCl, HNO{sub 3}, EDTA, CaCl{sub 2}, acetic acid, and tap water. HCl, HNO{sub 3}, and EDTA desorbed the majority of the soil-bound lead. Acetic acid and CaCl{sub 2} were less effective while tap water was ineffective. An experimental apparatus consisting of a consolidation unit and electrokinetic (EK) soil reactor to mimic EK flushing in the field was designed and constructed. The experimental unit underwent testing to determine if water could be moved through the soil under an applied electric current. Significant quantities of water were moved through soil. Based on limited results, water movement increased with increased conductivity. The pH and conductivity of the reservoir waters were monitored during the reactor testing. With time, the pH at the cathode dropped to less than 4 and at the anode was raised to about 10. Conductivities of the two reservoirs increased from their initial values because of ion migration from the soil into the reservoirs and the increase in either H{sup +} and OH{sup {minus}}.

Improvement of storage, handling, and transportability of fine coal. Quarterly technical progress report No. 7, July 1, 1995--September 30, 1995  

SciTech Connect

The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled Coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. The objectives of this project are to demonstrate that: The Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well in a commercial coal preparation plant. The wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation. A wet fine coal product thus converted to a solid fuel form can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems. The Mulled Coal circuit was installed in an empty bay at the Chetopa Preparation Plant. Equipment has been installed to divert a 2.7 tonnes/hr (3 tons/hr) slipstream of the froth concentrate to a dewatering centrifuge. The concentrated wet coal fines from the centrifuge dropped through a chute directly into a surge hopper and feed system for the Mulled Coal circuit. The Mulled Coal product was gravity discharged from the circuit to a truck or product discharge area from which it will be hauled to a stockpile located at the edge of the clean coal stockpile area. During the 3-month operating period, the facility produced 870 tonnes (966 tons) of the Muffed Coal for evaluation in various storage, handling, and transportation equipment and operations. Immediately following the production demonstration, the circuit was disassembled and the facility was decommissioned.

Rope and the art of knot-tying in the seafaring of the ancient Eastern Mediterranean  

E-Print Network (OSTI)

Fibers woven into cords or ropes and tied together with knots form one of mankind's earliest tools. When he first went out onto the water on anything more sophisticated than a simple paddle-driven dugout canoe he had to have done so with the assistance of some type of cordage. He may have needed a line tied around a stone that would serve as an anchor, a line to retrieve.his fishing spear, and a line to moor his craft on the beach. And soon he would need lines to hold a mast erect so he could raise a sail. In fact, no waterborne vessel, in ancient times, as today, could function without rope. As ships got larger and more complicated, the requirement for many different types and sizes of cordage became increasingly important. Depictions of seagoing vessels from the ancient eastern Mediterranean-Egyptian, Greek, Phoenician, or Roman--give some idea of the great quantities of cordage that would have been required to keep these ships at sea. Yet, when rope has been found on ancient shipwrecks, or in other nautical contexts, those examples have received comparatively little attention. Likewise, the overall subjects of the making of rope and the art of knot-tying in the ancient world, both without which ships could not have set sail, have received little attention. Evidence from antiquity that can open these subjects up to the modern world does exist. The Greek and Roman writers reveal a great deal about rope, and the materials used in its manufacture, although they are less open about knots. Ancient artists were less revealing with specific detail on rope and knots, but there is some information there. Archaeological remains of ancient rope are found on many shipwrecks and, while it occurs less often, a few knots have also been found on ancient sites. This thesis is a review of this material from the ancient world. It will provide insight into an important, but little known subject, and will add to our understanding of seafaring in the Mediterranean area during antiquity.

Bypassing the learning curve in permanent seed implants using state-of-the-art technology  

SciTech Connect

Purpose: The aim of this study was to demonstrate, based on clinical postplan dose distributions, that technology can be used efficiently to eliminate the learning curve associated with permanent seed implant planning and delivery. Methods and Materials: Dose distributions evaluated 30 days after the implant of the initial 22 consecutive patients treated with permanent seed implants at two institutions were studied. Institution 1 (I1) consisted of a new team, whereas institution 2 (I2) had performed more than 740 preplanned implantations over a 9-year period before the study. Both teams had adopted similar integrated systems based on three-dimensional (3D) transrectal ultrasonography, intraoperative dosimetry, and an automated seed delivery and needle retraction system (FIRST, Nucletron). Procedure time and dose volume histogram parameters such as D90, V100, V150, V200, and others were collected in the operating room and at 30 days postplan. Results: The average target coverage from the intraoperative plan (V100) was 99.4% for I1 and 99.9% for I2. D90, V150, and V200 were 191.4 Gy (196.3 Gy), 75.3% (73.0%), and 37.5% (34.1%) for I1 (I2) respectively. None of these parameters shows a significant difference between institutions. The postplan D90 was 151.2 Gy for I1 and 167.3 Gy for I2, well above the 140 Gy from the Stock et al. analysis, taking into account differences at planning, results in a p value of 0.0676. The procedure time required on average 174.4 min for I1 and 89 min for I2. The time was found to decrease with the increasing number of patients. Conclusion: State-of-the-art technology enables a new brachytherapy team to obtain excellent postplan dose distributions, similar to those achieved by an experienced team with proven long-term clinical results. The cost for bypassing the usual dosimetry learning curve is time, with increasing team experience resulting in shorter treatment times.

State-of-the-Art Highly Insulating Window Frames - Research and Market Review  

DOE Green Energy (OSTI)

This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m{sup 2}K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC. The frame research review also shows examples of window frames developed in order to increase the energy efficiency of the frames and the glazings which the frames are to be used together with. The authors find that two main tracks are used in searching for better solutions. The first one is to minimize the heat losses through the frame itself. The result is that conductive materials are replaced by highly thermal insulating materials and air cavities. The other option is to reduce the window frame area to a minimum, which is done by focusing on the net energy gain by the entire window (frame, spacer and glazing). Literature shows that a window with a higher U-value may give a net energy gain to a building that is higher than a window with a smaller U-value. The net energy gain is calculated by subtracting the transmission losses through the window from the solar energy passing through the windows. The net energy gain depends on frame versus glazing area, solar factor, solar irradiance, calculation period and U-value. The frame research review also discusses heat transfer modeling issues related to window frames. Thermal performance increasing measures, surface modeling, and frame cavity modeling are among the topics discussed. The review shows that the current knowledge gives the basis for improving the calculation procedures in the calculation standards. At the same time it is room for improvement within some areas, e.g. to fully understand the natural convection effects inside irregular vertical frame cavities (jambs) and ventilated frame cavities.

End-of-life vehicle recycling : state of the art of resource recovery from shredder residue.  

Science Conference Proceedings (OSTI)

Each year, more than 50 million vehicles reach the end of their service life throughout the world. More than 95% of these vehicles enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, about 75% of automotive materials are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobiles, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials (about 25% of the weight of the vehicle)--commonly called shredder residue--is disposed of in landfills. Over the past 10 to 15 years, a significant amount of research and development has been undertaken to enhance the recycle rate of end-of-life vehicles (ELVs), including enhancing dismantling techniques and improving remanufacturing operations. However, most of the effort has focused on developing technology to recover materials, such as polymers, from shredder residue. To make future vehicles more energy efficient, more lighter-weight materials--primarily polymers and polymer composites--will be used in manufacturing these vehicles. These materials increase the percentage of shredder residue that must be disposed of, compared with the percentage of metals. Therefore, as the complexity of automotive materials and systems increases, new technologies will be required to sustain and maximize the ultimate recycling of these materials and systems at end-of-life. Argonne National Laboratory (Argonne), in cooperation with the Vehicle Recycling Partnership (VRP) and the American Plastics Council (APC), is working to develop technology for recycling materials from shredder residue. Several other organizations worldwide are also working on developing technology for recycling shredder residue. Without a commercially viable shredder industry, our nation may face greater environmental challenges and a decreased supply of quality scrap and be forced to turn to primary ores for the production of finished metals. This document presents a review of the state of the art in shredder residue recycling. Available technologies and emerging technologies for the recycling of materials from shredder residue are discussed.

Using fine-scale fuel measurements to assess wildland fuels, potential fire behavior and hazard mitigation treatments in the southeastern USA.  

Science Conference Proceedings (OSTI)

The inherent spatial and temporal heterogeneity of fuelbeds in forests of the southeastern United States may require fine scale fuel measurements for providing reliable fire hazard and fuel treatment effectiveness estimates. In a series of five papers, an intensive, fine scale fuel inventory from the Savanna River Site in the southeastern United States is used for building fuelbeds and mapping fire behavior potential, evaluating fuel treatment options for effectiveness, and providing a comparative analysis of landscape modeled fire behavior using three different data sources including the Fuel Characteristic Classification System, LANDFIRE, and the Southern Wildfire Risk Assessment. The research demonstrates that fine scale fuel measurements associated with fuel inventories repeated over time can be used to assess broad scale wildland fire potential and hazard mitigation treatment effectiveness in the southeastern USA and similar fire prone regions. Additional investigations will be needed to modify and improve these processes and capture the true potential of these fine scale data sets for fire and fuel management planning.

Engineering Development of Advanced Physical Fine Coal Cleaning for Premium Fuel Applications: Task 9 - Selective agglomeration Module Testing and Evaluation.  

SciTech Connect

The primary goal of this project was the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope included laboratory research and bench-scale testing of both processes on six coals to optimize the processes, followed by the design, construction, and operation of a 2 t/hr process development unit (PDU). The project began in October, 1992, and is scheduled for completion by September 1997. This report summarizes the findings of all the selective agglomeration (SA) test work performed with emphasis on the results of the PDU SA Module testing. Two light hydrocarbons, heptane and pentane, were tested as agglomerants in the laboratory research program which investigated two reactor design concepts: a conventional two-stage agglomeration circuit and a unitized reactor that combined the high- and low-shear operations in one vessel. The results were used to design and build a 25 lb/hr bench-scale unit with two-stage agglomeration. The unit also included a steam stripping and condensation circuit for recovery and recycle of heptane. It was tested on six coals to determine the optimum grind and other process conditions that resulted in the recovery of about 99% of the energy while producing low ash (1-2 lb/MBtu) products. The fineness of the grind was the most important variable with the D80 (80% passing size) varying in the 12 to 68 micron range. All the clean coals could be formulated into coal-water-slurry-fuels with acceptable properties. The bench-scale results were used for the conceptual and detailed design of the PDU SA Module which was integrated with the existing grinding and dewatering circuits. The PDU was operated for about 9 months. During the first three months, the shakedown testing was performed to fine tune the operation and control of various equipment. This was followed by parametric testing, optimization/confirmatory testing, and finally a 72-hour round the clock production run for each of the three project coals (Hiawatha, Taggart, and Indiana VII). The parametric testing results confirmed that the Taggart coal ground to a D80 of 30 microns could be cleaned to 1 lb ash/MBtu, whereas the Hiawatha and Indiana Vil coals had to be ground to D80s of 40 and 20 microns, respectively, to be cleaned to 2 lb ash/MBtu. The percent solids, residence time, shear intensity (impeller tip speed and energy input per unit volume), and heptane dosage were the main variables that affected successful operation (phase inversion or microagglomerate formation in the high-shear reactor and their growth to 2-3 mm in size during low shear). Downward inclination of the vibrating screen and adequate spray water helped produce the low ash products. Btu recoveries were consistently greater than 98%. Two-stage steam stripping achieved about 99% heptane recovery for recycle to the process. Residual hydrocarbon concentrations were in the 3000 to 5000 ppm range on a dry solids basis.

Gadolinium can be dissolved in sodium-alumino-borosilicate glasses up to 47 wt% in a baseline borosilicate glass (mol%) 20 B2O3, 5 Al2O3, 60 SiO2,and 20 Na2O. Understanding of Gd dissolution in borosilicate melts is important in glass formulation optimization. Electron energy loss fine structure (ELFS) spectroscopy is chosen, which provides well resolved local atomic structure information for both amorphous and crystalline materials with high sensitivity to low Z elements such as Al, B, Na, O, and Si where the x-ray absorption fine structure (XAFS) technique faces experimental difficulty. In this study, we report our results of boron K-edge ELFS study. Two borosilicate glass samples with 30 and 47 mass% Gd2O3, B20Gd30 and B20Gd47were chosen for B K-edge ELFS study. EEL spectra were acquired on a Philips 430 TEM equipped with Gatan PEELS system 666 and EL/P 2.1 software with Custom function AcqLong. The ELFS data analysis was performed using UWELFS, UWXAFS and FEFF software. From our Gd solubility study, the local structure of Gd in the borate environment possibly resembles double chain structure found in crystalline Gd(BO2)3 as proposed by Chakraborty et al. The B/Gd ratio's in both glasses are smaller then 3, which means the excess Gd atoms in the Si-sites would be 17 and 60 mol% of the total Gd atoms, respectively according to the model, yet the local environment of borate sites saturated with Gd should be remained. To verity above hypothesis, the double chain structure model was applied to fit boron K-edge. The model was shown to well fit experimental boron K-edge EELS spectra for both glasses with some degree of distance distortion which is understandable in amorp
