Affine Defects and Gravitation  

E-Print Network (OSTI)

We argue that the structure general relativity (GR) as a theory of affine defects is deeper than the standard interpretation as a metric theory of gravitation. Einstein-Cartan theory (EC), with its inhomogenous affine symmetry, should be the standard-bearer for GR-like theories. A discrete affine interpretation of EC (and gauge theory) yields topological definitions of momentum and spin (and Yang Mills current), and their conservation laws become discrete topological identities. Considerations from quantum theory provide evidence that discrete affine defects are the physical foundation for gravitation.

Generation of gaseous tritium standards  

SciTech Connect

The determination of aqueous and non-aqueous tritium in gaseous samples is one type of determination often requested of radioanalytical laboratories. This determination can be made by introducing the sample as a gas into a sampling train containing two silica gel beds separated by.a catalytic oxidizer bed. The first bed traps tritiated water. The sample then passes into and through the oxidizer bed where non-aqueous tritium containing species are oxidized to water and other products of combustion. The second silica gel bed then traps the newly formed tritiated water. Subsequently, silica gel is removed to plastic bottles, deionized water is added, and the mixture is permitted to equilibrate. The tritium content of the equilibrium mixture is then determined by conventional liquid scintillation counting (LSC). For many years, the moisture content of inert, gaseous samples has been determined using monitors which quantitatively electrolyze the moisture present after that moisture has been absorbed by phosphorous pentoxide or other absorbents. The electrochemical reaction is quantitative and definitive, and the energy consumed during electrolysis forms the basis of the continuous display of the moisture present. This report discusses the experimental evaluation of such a monitor as the basis for a technique for conversion of small quantities of SRMs of tritiated water ({sup 3}HOH) into gaseous tritium standards ({sup 3}HH).

Purely affine Gravity  

E-Print Network (OSTI)

We develop a topological theory of gravity with torsion where metric has a dynamical rather than a kinematical origin. This approach towards gravity resembles pre-geometrical approaches in which a fundamental metric does not exist, but the affine connection gives place to a local inertial structure. Such feature reminds us of Mach's principle, that assumes the inertial forces should have dynamical origin. Additionally, a Newtonian gravitational force is obtained in the non-relativistic limit of the theory.

Hydrogen and Gaseous Fuel Safety and Toxicity  

SciTech Connect

Non-traditional motor fuels are receiving increased attention and use. This paper examines the safety of three alternative gaseous fuels plus gasoline and the advantages and disadvantages of each. The gaseous fuels are hydrogen, methane (natural gas), and propane. Qualitatively, the overall risks of the four fuels should be close. Gasoline is the most toxic. For small leaks, hydrogen has the highest ignition probability and the gaseous fuels have the highest risk of a burning jet or cloud.

Muon Capture in Gaseous Deuterium  

Science Journals Connector (OSTI)

We report the results of an experiment performed to measure the muon nuclear capture rate by free deuterons. The muons were slowed down in ultrapure gaseous hydrogen at 7.6 atm and 293 °K, containing 5% of deuterium. A special target was used, in which a system of gas proportional counters, working with the (H2 + D2) gaseous mixture itself, was operating. Neutrons from the capture reactions were detected using liquid scintillation counters, and the ?-ray background was eliminated by pulse-shape discrimination. The experimental result is ?exp=(445±60) sec-1, which is consistent with muon-electron universality and with the assumption that the nuclear capture proceeds from the doublet spin state of the ?d muonic atoms. Combining the present experimental value with a previous result obtained with a liquid-hydrogen deuterated target, one obtains a ratio between the axial-vector and vector coupling constants given by gA,?gV,?=-1.35±0.1.

Combination free electron and gaseous laser  

DOE Patents (OSTI)

A multiple laser having one or more gaseous laser stages and one or more free electron stages. Each of the free electron laser stages is sequentially pumped by a microwave linear accelerator. Subsequently, the electron beam is directed through a gaseous laser, in the preferred embodiment, and in an alternative embodiment, through a microwave accelerator to lower the energy level of the electron beam to pump one or more gaseous lasers. The combination laser provides high pulse repetition frequencies, on the order of 1 kHz or greater, high power capability, high efficiency, and tunability in the synchronous production of multiple beams of coherent optical radiation.

Muon Capture in Gaseous Hydrogen  

Science Journals Connector (OSTI)

An experiment to measure the muon nuclear capture rate in ultrapure gaseous hydrogen (8 atm, 293°K) has been performed using a special target in which a system of gas proportional counters, working with the pure hydrogen of the target itself, were operating. Neutrons from the capture reactions were detected using a scintillation-counter technique, and the ?-ray background was eliminated by pulse-shape discrimination. The working conditions ensured that the captures were taking place in ?p atomic systems in a singlet total-spin state. The experimental result is ?expt=651±57 sec-1, which has to be compared with the theoretical rate ?s, theor=626±26 sec-1. From the experimental capture rate, and within the framework of the currently accepted theory, we have obtained for the induced pseudoscalar coupling constant gp=(-7.3±3.7)gV. The results of the present experiment are analyzed, together with results obtained from stopping negative muons in liquid hydrogen.

Viscosity of gaseous ethyl fluoride (HFC-161)  

Science Journals Connector (OSTI)

Abstract The paper describes an improved Maxwell type oscillating-disk viscometer. The experimental system was calibrated by argon, carbon dioxide, nitrogen, hydrogen and verified by nitrogen. The viscosities of gaseous HFC-161 were measured from 293 K to 369 K at pressures from 0.1 MPa up to the saturated vapor pressure. An empirical viscosity equation is proposed to interpolate the present experimental data as a function of density and temperature. The uncertainty of the reported viscosity was estimated to be within 1%.

Thermal conductivity of graphene nanoribbons in noble gaseous environments  

SciTech Connect

We investigate the thermal conductivity of suspended graphene nanoribbons in noble gaseous environments using molecular dynamics simulations. It is reported that the thermal conductivity of perfect graphene nanoribbons decreases with the gaseous pressure. The decreasing is more obvious for the noble gas with large atomic number. However, the gaseous pressure cannot change the thermal conductivity of defective graphene nanoribbons apparently. The phonon spectra of graphene nanoribbons are also provided to give corresponding supports.

Gaseous-fuel safety assessment. Status report  

SciTech Connect

The Los Alamos National Laboratory, in support of studies sponsored by the Office of Vehicle and Engine Research and Development in the US Department of Energy, has undertaken a safety assessment of selected gaseous fuels for use in light automotive transportation. The purpose is to put into perspective the hazards of these fuels relative to present day fuels and delineated criteria for their safe handling. Fuels include compressed and liquified natural gas (CNG and LNG), liquefied petroleum gas (LPG), and for reference gasoline and diesel. This paper is a program status report. To date, physicochemical property data and general petroleum and transportation information were compiled; basic hazards defined; alternative fuels were safety-ranked based on technical properties alone; safety data and vehicle accident statistics reviewed; and accident scenarios selected for further analysis. Methodology for such analysis is presently under consideration.

Simulating the Gaseous Halos of Galaxies  

E-Print Network (OSTI)

Observations of local X-ray absorbers, high-velocity clouds, and distant quasar absorption line systems suggest that a significant fraction of baryons may reside in multi-phase, low-density, extended, ~100 kpc, gaseous halos around normal galaxies. We present a pair of high-resolution SPH (smoothed particle hydrodynamics) simulations that explore the nature of cool gas infall into galaxies, and the physical conditions necessary to support the type of gaseous halos that seem to be required by observations. The two simulations are identical other than their initial gas density distributions: one is initialized with a standard hot gas halo that traces the cuspy profile of the dark matter, and the other is initialized with a cored hot halo with a high central entropy, as might be expected in models with early pre-heating feedback. Galaxy formation proceeds in dramatically different fashions in these two cases. While the standard cuspy halo cools rapidly, primarily from the central region, the cored halo is quasi-stable for ~4 Gyr and eventually cools via the fragmentation and infall of clouds from ~100 kpc distances. After 10 Gyr of cooling, the standard halo's X-ray luminosity is ~100 times current limits and the resultant disk galaxy is twice as massive as the Milky Way. In contrast, the cored halo has an X-ray luminosity that is in line with observations, an extended cloud population reminiscent of the high-velocity cloud population of the Milky Way, and a disk galaxy with half the mass and ~50% more specific angular momentum than the disk formed in the low-entropy simulation. These results suggest that the distribution and character of halo gas provides an important testing ground for galaxy formation models and may be used to constrain the physics of galaxy formation.

Improving image segmentation by learning region affinities  

SciTech Connect

We utilize the context information of other regions in hierarchical image segmentation to learn new regions affinities. It is well known that a single choice of quantization of an image space is highly unlikely to be a common optimal quantization level for all categories. Each level of quantization has its own benefits. Therefore, we utilize the hierarchical information among different quantizations as well as spatial proximity of their regions. The proposed affinity learning takes into account higher order relations among image regions, both local and long range relations, making it robust to instabilities and errors of the original, pairwise region affinities. Once the learnt affinities are obtained, we use a standard image segmentation algorithm to get the final segmentation. Moreover, the learnt affinities can be naturally unutilized in interactive segmentation. Experimental results on Berkeley Segmentation Dataset and MSRC Object Recognition Dataset are comparable and in some aspects better than the state-of-art methods.

Microbial production of energy: gaseous fuels  

SciTech Connect

Although several gaseous fuels could be derived by microbial fermentation, in the near term it will be economical to produce biomethane by anaerobic digestion of readily available heterogeneous feeds that may be obtained free or at low cost. Various wastes and biomass species grown in polluted waters are attractive feeds for commercial methane production. Biomethane could meet significant portions of the energy requirements of a number of countries. The conventional digestion-process configurations used for sewage sludge digestion were developed to ensure fail-safe maximized sludge stabilization, and are not necessarily suitable for maximized energy production. Commercial biomethane energy plants must be designed to optimize the net methane income production rate. Separate process designs are needed to effect optimized conversion of soluble, semisolid and solid feeds. Several approaches to improved process designs may be considered. The approaches include development of innovative fermentation modes, application of novel reactor designs, development of cost-effective pre/post-treatment techniques for feeds and unconverted residues, use of biostimulants, and development of new microbial strains. The last two approaches may not be feasible in the near future. In the near term, the objective of economical biomethane production at short HRT's and high loadings may be realized by applying new fermentation modes, such as two-phase digestion, and by utilizing new reactor designs, such as upflow digesters, the packed-bed reactors, plug-flow digesters, biodisc reactors, and others. The two-phase process has exhibited the highest reported methane yields from several soluble and particulate feeds and holos considerable commercialization potential. A number of new biomethanation processes have been proven feasible within the last decade by pilot- and commercial-scale application. 95 references, 14 figures, 12 tables.

Designer Affinity Reagents Designer Affinity Reagents B. Kay Single-chain variable fragments (scFv) can be displayed on the surface of the bacteriophage M13 and still function in selectively binding their antigens. Even though these antibody fragments are much smaller (25 vs. 150 kDa) than the intact molecules, they can bind their antigens with exquisite sensitivity and specificity. Libraries of scFv antibodies can be screened by affinity selection for binding to any type of target, such as a protein or an organic molecule. The resulting isolated antibodies can be used in a wide variety of applications (e.g., detectors, crystallization agents, and modifiers of target activity). In addition, such antibodies can be used as adapters that bridge inert materials in a defined manner, and thus may be excellent tools for building nanostructures.

Asymptotic representations of quantum affine superalgebras  

E-Print Network (OSTI)

We study representations of the $q$-Yangian, the upper Borel subalgebra with respect to RTT realization of the quantum affine superalgebra associated with the Lie superalgebra $\\mathfrak{gl}(M,N)$. Following the work of Hernandez-Jimbo, we construct inductive systems of Kirillov-Reshetikhin modules by using a cyclicity result of tensor products of these modules we established recently, and realize their inductive limits as modules over the $q$-Yangian, extending the asymptotic construction of Hernandez-Jimbo to the super case. Then, we propose a new asymptotic construction on the inductive limits of the same inductive systems, resulting in modules over the full quantum affine superalgebra depending on an additional parameter. $q$-character and Gelfand-Tsetlin basis for these two kinds of modules are also investigated.

ParCAT: Parallel Climate Analysis Toolkit  

SciTech Connect

Climate science is employing increasingly complex models and simulations to analyze the past and predict the future of Earth s climate. This growth in complexity is creating a widening gap between the data being produced and the ability to analyze the datasets. Parallel computing tools are necessary to analyze, compare, and interpret the simulation data. The Parallel Climate Analysis Toolkit (ParCAT) provides basic tools to efficiently use parallel computing techniques to make analysis of these datasets manageable. The toolkit provides the ability to compute spatio-temporal means, differences between runs or differences between averages of runs, and histograms of the values in a data set. ParCAT is implemented as a command-line utility written in C. This allows for easy integration in other tools and allows for use in scripts. This also makes it possible to run ParCAT on many platforms from laptops to supercomputers. ParCAT outputs NetCDF files so it is compatible with existing utilities such as Panoply and UV-CDAT. This paper describes ParCAT and presents results from some example runs on the Titan system at ORNL.

A Numerical Study on Gaseous Reactions in Silane Pyrolysis  

Science Journals Connector (OSTI)

A simple gaseous reaction model involving 11 elementary reactions for 10 chemical species is proposed for silane and disilane pyrolyses at 550–750 K; its appropriateness is examined by a calculation based on an one-dimensional nonsteady condition which includes gaseous reactions, diffusional transport and radical adsorptions. The calculated results show that the model can successfully explain the experimental behavior of a gas composition concerning the time lag of hydrogen molecule production as well as the temperature and pressure dependences of the saturated higher silane concentrations. The reaction model is applied to a SiH4–H2–N2 system; it predicts that dilution with hydrogen or the premixing of c.a. 4% of disilane is useful for obtaining a spatially uniform deposition rate in a flow-type CVD reactor.

Paducah Gaseous Diffusion Plant environmental report for 1992  

SciTech Connect

This two-part report, Paducah Gaseous Diffusion Plant Environmental Report for 1992, is published annually. It reflects the results of an environmental monitoring program designed to quantify potential increases in the concentration of contaminants and potential doses to the resident human population. The Paducah Gaseous Diffusion Plant (PGDP) overall goal for environmental management is to protect the environment and PGDP`s neighbors and to maintain full compliance with all current regulations. The current environmental strategy is to identify any deficiencies and to develop a system to resolve them. The long-range goal of environmental management is to minimize the source of pollutants, reduce the generation of waste, and minimize hazardous waste by substitution of materials.

Isotropic collision-induced light scattering by gaseous CF4  

Science Journals Connector (OSTI)

The binary isotropic collision-induced scattering spectra of the gaseous tetrafluoromethane has been measured in absolute units in the 50–150 cm-1 frequency range. Corresponding theoretical intensities taking into account multipolar polarizabilities have been calculated in a semiclassical way. From a comparison with experiment, the independent components of dipole-quadrupole and dipole-octupole polarizability tensors have been estimated. They have been compared with those previously deduced from depolarized spectrum and with recent theoretical ab initio calculations.

Onsite Gaseous Centrifuge Enrichment Plant UF6 Cylinder Destructive Analysis  

SciTech Connect

The IAEA safeguards approach for gaseous centrifuge enrichment plants (GCEPs) includes measurements of gross, partial, and bias defects in a statistical sampling plan. These safeguard methods consist principally of mass and enrichment nondestructive assay (NDA) verification. Destructive assay (DA) samples are collected from a limited number of cylinders for high precision offsite mass spectrometer analysis. DA is typically used to quantify bias defects in the GCEP material balance. Under current safeguards measures, the operator collects a DA sample from a sample tap following homogenization. The sample is collected in a small UF6 sample bottle, then sealed and shipped under IAEA chain of custody to an offsite analytical laboratory. Current practice is expensive and resource intensive. We propose a new and novel approach for performing onsite gaseous UF6 DA analysis that provides rapid and accurate assessment of enrichment bias defects. DA samples are collected using a custom sampling device attached to a conventional sample tap. A few micrograms of gaseous UF6 is chemically adsorbed onto a sampling coupon in a matter of minutes. The collected DA sample is then analyzed onsite using Laser Ablation Absorption Ratio Spectrometry-Destructive Assay (LAARS-DA). DA results are determined in a matter of minutes at sufficient accuracy to support reliable bias defect conclusions, while greatly reducing DA sample volume, analysis time, and cost.

Ionization and scintillation of nuclear recoils in gaseous xenon  

E-Print Network (OSTI)

Ionization and scintillation produced by nuclear recoils in gaseous xenon at approximately 14 bar have been simultaneously observed in an electroluminescent time projection chamber. Neutrons from radioisotope $\\alpha$-Be neutron sources were used to induce xenon nuclear recoils, and the observed recoil spectra were compared to a detailed Monte Carlo employing estimated ionization and scintillation yields for nuclear recoils. The ability to discriminate between electronic and nuclear recoils using the ratio of ionization to primary scintillation is demonstrated. These results encourage further investigation on the use of xenon in the gas phase as a detector medium in dark matter direct detection experiments.

Low energy consumption method for separating gaseous mixtures and in particular for medium purity oxygen production  

DOE Patents (OSTI)

A method for the separation of gaseous mixtures such as air and for producing medium purity oxygen, comprising compressing the gaseous mixture in a first compressor to about 3.9-4.1 atmospheres pressure, passing said compressed gaseous mixture in heat exchange relationship with sub-ambient temperature gaseous nitrogen, dividing the cooled, pressurized gaseous mixture into first and second streams, introducing the first stream into the high pressure chamber of a double rectification column, separating the gaseous mixture in the rectification column into a liquid oxygen-enriched stream and a gaseous nitrogen stream and supplying the gaseous nitrogen stream for cooling the compressed gaseous mixture, removing the liquid oxygen-enriched stream from the low pressure chamber of the rectification column and pumping the liquid, oxygen-enriched steam to a predetermined pressure, cooling the second stream, condensing the cooled second stream and evaporating the oxygen-enriched stream in an evaporator-condenser, delivering the condensed second stream to the high pressure chamber of the rectification column, and heating the oxygen-enriched stream and blending the oxygen-enriched stream with a compressed blend-air stream to the desired oxygen concentration.

Mevva ion source operated in purely gaseous mode  

SciTech Connect

We have operated a vacuum arc ion source in such a way as to form beams of purely gaseous ions. The vacuum arc configuration that is conventionally used to produce intense beams of metal ions was altered so as to form gaseous ion beams, with only minimal changes to the external circuitry and no changes at all internally to the ion source. In our experiments we formed beams from oxygen (O{sup +} and O{sub 2}{sup +}), nitrogen (N{sup +} and N{sub 2}{sup +}), argon (Ar{sup +}) and carbon dioxide (C{sup +}, CO{sub 2}{sup +}, O{sup +} and O{sub 2}{sup +}) at extraction voltage of 2 to 50 kV. We used a pulsed mode of operation, with beam pulses approximately 50 milliseconds long and repetition rate 10 pulses per second, for a duty cycle of about 50%. Downstream ion beam current as measured by a 5 cm diameter Faraday cup was typically 0.5 mA pulse or about 250 {micro}A time averaged. This time averaged beam current is very similar to that obtained for metal ions when the source is operated in the usual vacuum arc mode. Here we describe the modifications made to the source and the results of our investigations.

Gridless, very low energy, high-current, gaseous ion source  

SciTech Connect

We have made and tested a very low energy gaseous ion source in which the plasma is established by a gaseous discharge with electron injection in an axially diverging magnetic field. A constricted arc with hidden cathode spot is used as the electron emitter (first stage of the discharge). The electron flux so formed is filtered by a judiciously shaped electrode to remove macroparticles (cathode debris from the cathode spot) from the cathode material as well as atoms and ions. The anode of the emitter discharge is a mesh, which also serves as cathode of the second stage of the discharge, providing a high electron current that is injected into the magnetic field region where the operating gas is efficiently ionized. In this discharge configuration, an electric field is formed in the ion generation region, accelerating gas ions to energy of several eV in a direction away from the source, without the use of a gridded acceleration system. Our measurements indicate that an argon ion beam is formed with an energy of several eV and current up to 2.5 A. The discharge voltage is kept at less than 20 V, to keep below ion sputtering threshold for cathode material, a feature which along with filtering of the injected electron flow, results in extremely low contamination of the generated ion flow.

Recent gaseous divertor experiments in DIII-D  

SciTech Connect

The expected heat loads at the divertor plates for next generation tokamaks raise concern from the standpoints of both mechanical integrity and erosion rate. The peak heat flux anticipated for the present International Thermonuclear Experimental Reactor (ITER) design are predicted to be as high as {approximately}20 MW/m{sup 2}. High peak heat fluxes can be reduced to more manageable levels by increasing the radiated power in the divertor, which has the additional benefit of reducing divertor plasma temperature and sheath potential, thereby lowering the ion impact energy. Neutral deuterium gas injection into or near the divertor has been suggested as one means of reducing heat flux via radiation and/or momentum transfer and ionization collisions with the neutral gas; this method is often referred to as the gaseous divertor.'' In this paper we report on experiments in which the gaseous divertor approach was used to reduce the heat flux on the divertor tiles of the DIII-D tokamak during ELMing H-mode discharges. 7 refs., 4 figs.

Gaseous diffusion plant transition from DOE to external regulation  

SciTech Connect

After many years of operation as government-owned/contractor-operated facilities, large portions of the gaseous diffusion plants (GDPs) at Portsmouth, Ohio, and Paducah, Kentucky, were leased to the United States Enrichment Corporation (USEC). These facilities are now certified by the U.S. Nuclear Regulatory Commission (NRC) and subject to oversight by the Occupational Safety and Health Administration (OSHA). The transition from DOE to NRC regulation was more difficult than expected. The original commitment was to achieve NRC certification in October 1995; however, considerably more time was required and transition-related costs escalated. The Oak Ridge Operations Office originally estimated the cost of transition at $60 million; $240 million has been spent to date. The DOE`s experience in transitioning the GDPs to USEC operation with NRC oversight provides valuable lessons (both positive and negative) that could be applied to future transitions.

Spectral modeling of gaseous metal disks around DAZ white dwarfs  

E-Print Network (OSTI)

We report on our attempt for the first non-LTE modeling of gaseous metal disks around single DAZ white dwarfs recently discovered by Gaensicke et al. and thought to originate from a disrupted asteroid. We assume a Keplerian rotating viscous disk ring composed of calcium and hydrogen and compute the detailed vertical structure and emergent spectrum. We find that the observed infrared CaII emission triplet can be modeled with a hydrogen-deficient gas ring located at R=1.2 R_sun, inside of the tidal disruption radius, with Teff about 6000 K and a low surface mass density of about 0.3 g/cm**2. A disk having this density and reaching from the central white dwarf out to R=1.2 R_sun would have a total mass of 7 10**21 g, corresponding to an asteroid with about 160 km diameter.

Radiation Tests for a Single-GEM Loaded Gaseous Detector  

E-Print Network (OSTI)

We report on the systematic study of a single-gas-electron-multiplication (GEM) loaded gaseous detector developed for precision measurements of high-energy particle beams and dose-verification measurements. In the present study, a 256-channel prototype detector with an active area of 16$\\times$16 cm$^{2}$, operated in a continuous current-integration-mode signal-processing method, was manufactured and tested with x rays emitted from a 70-kV x-ray generator and 43-MeV protons provided by the MC50 proton cyclotron at the Korea Institute of Radiological and Medical Science (KIRAMS). The amplified detector response was measured for the x rays with an intensity of about 5$\\times$10$^{6}$ Hz cm$^{-2}$. The linearity of the detector response to the particle flux was examined and validated by using 43-MeV proton beams. The non-uniform development of the amplification for the gas electrons in space was corrected by applying proper calibration to the channel responses of the measured beam-profile data. We concluded fro...

Gaseous fueled vehicles: A role for natural gas and hydrogen  

SciTech Connect

The commercialization of gaseous hydrogen fueled vehicles requires both the development of hydrogen fueled vehicles and the establishment of a hydrogen fueling infrastructure. These requirements create a classic chicken and egg scenario in that manufacturers will not build and consumers will not buy vehicles without an adequate refueling infrastructure and potential refueling station operators will not invest the needed capital without an adequate market to serve. One solution to this dilemma is to create a bridging strategy whereby hydrogen is introduced gradually via another carrier. The only contending alternative fuel that can act as a bridge to hydrogen fueled vehicles is natural gas. To explore this possibility, IGT is conducting emission tests on its dedicated natural gas vehicle (NGV) test platform to determine what, if any, effects small quantities of hydrogen have on emissions and performance. Furthermore, IGT is actively developing an adsorbent based low-pressure natural gas storage system for NGV applications. This system has also shown promise as a storage media for hydrogen. A discussion of our research results in this area will be presented. Finally, a review of IGT's testing facility will be presented to indicate our capabilities in conducted natural gas/hydrogen vehicle (NGHV) research. 3 refs., 10 figs.

Effect of gaseous inhibitors on PCDD/F formation  

SciTech Connect

Emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) from municipal waste incineration are currently a subject of considerable public concern because of their extreme toxicity. PCDD/F formation in incineration processes is being studied widely, but studies on inhibition are quite sparse, especially in a pilot-plant scale. In this work, the effect of four gaseous inhibitors (sulfur dioxide, ammonia, dimethylamine, and methyl mercaptan) on PCDD/PCDF formation in the combustion of liquid fuel was studied using a pilot-scale plant. The inhibitors were injected into the flue gas stream after the first economizer at a temperature of 670 C and just before the second economizer at 410 C. Both the chlorophenol and PCDD and PCDF concentrations decreased when inhibitors were added. Particle-phase PCDD/F concentrations in particular decreased by up to 98%. The results suggest that the formation of PCDD/Fs is hindered in the particle phase at the early stages of the PCDD/F formation chain, probably even before precursors such as chlorophenols have been formed.

Paducah Gaseous Diffusion Plant Northwest Plume interceptor system evaluation  

SciTech Connect

The Paducah Gaseous Diffusion Plant (PGDP) recently installed an interceptor system consisting of four wells, evenly divided between two well fields, to contain the Northwest Plume. As stated in the Northwest Plume Record of Decision (ROD), groundwater will be pumped at a rate to reduce further contamination and initiate control of the northwest contaminant plume. The objective of this evaluation was to determine the optimum (minimal) well field pumping rates required for plume hotspot containment. Plume hotspot, as defined in the Northwest Plume ROD and throughout this report, is that portion of the plume with trichloroethene (TCE) concentrations greater than 1,000 {micro}g/L. An existing 3-dimensional groundwater model was modified and used to perform capture zone analyses of the north and south interceptor system well fields. Model results suggest that the plume hotspot is not contained at the system design pumping rate of 100 gallons per minute (gal/min) per well field. Rather, the modeling determined that north and south well field pumping rates of 400 and 150 gal/min, respectively, are necessary for plume hotspot containment. The difference between the design and optimal pumping rates required for containment can be attributed to the discovery of a highly transmissive zone in the vicinity of the two well fields.

Hybrid Multi Micropattern Gaseous Photomultiplier for detection of liquid-xenon scintillation  

E-Print Network (OSTI)

Gaseous PhotoMultipliers (GPM) are a very promising alternative of vacuum PMTs especially for large-size noble-liquid detectors in the field of Functional Nuclear Medical Imaging and Direct Dark Matter Detection. We present recent characterization results of a Hybrid-GPM made of three Micropattern Gaseous Structures; a Thick Gaseous Electron Multiplier (THGEM), a Parallel Ionization Multiplier (PIM) and a MICROMesh GAseous Structure (MICROMEGAS),operating in Ne/CF4 (90:10). Gain values close to 10^7 were recorded in this mixture, with 5.9keV x-rays at 1100 mbar, both at room temperature and at that of liquid xenon (T = 171K). The results are discussed in term of scintillation detection. While the present multiplier was investigated without photocathode, complementary results of photoextraction from CsI UV photocathodes are presented in Ne/CH4 (95:5) and CH4 in cryogenic conditions.

Selective affinity of pirenzepine analogues for subtypes of muscarinic receptors  

SciTech Connect

Pirenzepine (PZ), telenzepine (TZ) and quinuclidinyl xanthene-9-carboxylate (QNX) are antimuscarinic agents containing a tricyclic ring system and a basic side chain that have been reported to have selective affinity for the M/sub 1/ subtype of receptor. They have prepared and examined seven new PZ analogues containing modifications in either the tricyclic ring system, the side-chain, or both. Affinity for M/sub 1/ type receptors was determined by displacement of specifically-bound (/sup 3/H)PZ from rat cerebral cortex homogenates. Affinity for M/sub 2/ type receptors was measured on rat heart homogenate using (/sup 3/H)(-)quinuclidinyl benzilate. The ratio of the K/sub i/'s for M/sub 1/ and M/sub 2/ receptors were calculated and compared to PZ. All of the compounds had a higher affinity for M/sub 1/ than M/sub 2/ receptors. Three of the compounds were comparable to PZ in selectivity, but the more selective compounds had a weaker affinity for M/sub 1/ receptors. TZ and QNX were less selective than PZ.

Phyto remediation groundwater trends at the DOE portsmouth gaseous  

SciTech Connect

This paper describes the progress of a phyto-remediation action being performed at the Department of Energy (DOE) Portsmouth Gaseous Diffusion Plant (PORTS) X-740 Waste Oil Handling Facility to remediate contaminated groundwater under a Resource Conservation and Recovery Act (RCRA) closure action. This action was effected by an Ohio Environmental Protection Agency (OEPA) decision to use phyto-remediation as the preferred remedy for the X-740 groundwater contamination. This remedy was recognized as a cost-effective, low-maintenance, and promising method to remediate groundwater contaminated with volatile organic compounds (VOCs), primarily trichloroethylene (TCE). During 1999, prior to the tree installation at the X-740 Phyto-remediation Area, water level measurements in the area were collected from 10 monitoring wells completed in the Gallia Formation. The Gallia is the uppermost water-bearing zone and contains most of the groundwater contamination at PORTS. During the tree installation which took place during the summer of 1999, four new Gallia monitoring wells were installed at the X-740 Area in addition to the 10 Gallia wells which had been installed in the same area during the early 1990's. Manual water level measurements were collected quarterly from these 14 Gallia monitoring wells between 1998 and 2001. These manual water level measurements were collected to monitor the combined impact of the trees on the groundwater prior to root development. Beginning in 2001, water level measurements were collected monthly during the growing season (April-September) and quarterly during the dormant season (October-March). A total of eight water level measurements were collected annually to monitor the phyto-remediation system's effect on the groundwater in the X- 740 Area. The primary function of the X-740 Phyto-remediation Area is to hydraulically prevent further spreading of the TCE plume. This process utilizes deep-rooted plants, such as poplar trees, to extract large quantities of water from the saturated zone. The focus of any phyto-remediation system is to develop a cone of depression under the entire plantation area. This cone of depression can halt migration of the contaminant plume and can create a hydraulic barrier, thereby maintaining plume capture. While a cone of depression is not yet evident at the X-740 Phyto-remediation Area, water level measurements in 2004 and 2005 differed from measurements taken in previous years, indicating that the now mature trees are influencing groundwater flow direction and gradient at the site. Water level measurements taken from 2003 through 2005 indicate a trend whereby groundwater elevations steadily decreased in the X-740 Phyto-remediation System. During this time, an average groundwater table drop of 0.30 feet was observed. Although the time for the phyto-remediation system to mature had been estimated at two to three years, these monitoring data indicate a period of four to five years for the trees to reach maturity. Although, these trends are not apparent from analysis of the potentiometric surface contours, it does appear that the head gradient across the site is higher during the spring and lower during the fall. It is not clear, however, whether this trend was initiated by the installation of the phyto-remediation system. This paper will present the groundwater data collected to date to illustrate the effects of the trees on the groundwater table. (authors)

Detonation and deflagration characteristics of p-Xylene/gaseous hydrocarbon fuels/air mixtures  

Science Journals Connector (OSTI)

Abstract p-Xylene is an important intermediate for the production of polyethylene terephthalate, it has growing chemical industrial demand based on the statistics in the last few decades. In the process of producing p-Xylene, gaseous hydrocarbon fuels (e.g., H2, C1–C3) are usually involved, which renders p-Xylene highly possible mix with those gaseous hydrocarbon fuels as leaking occurs, this presents fire or explosion/detonation hazard at some specific conditions. To date, very limited data regarding its detonation and deflagration characteristics are available in previous literatures. In this study, experiments of measuring the overpressure and velocity of p-Xylene/gaseous hydrocarbon fuels (i.e., H2, C2H4, C3H8, CO)/air mixtures are carried out in a vertical detonation tube with an inner diameter of 200 mm and a length of 6.5 m to explore the detonation and deflagration characteristics of p-Xylene. The experimental results indicate that under the same initiation energy of 0.189 MJ m?2, pure p-Xylene/air and p-Xylene/CO/air cannot achieve detonation, only deflagrations are observed. However, under this same initiation energy, detonations occur in p-Xylene/H2/air, p-Xylene/C2H4/air and p-Xylene/C3H8/air mixtures. By comparing the combinatorial compositions of p-Xylene along with gaseous hydrocarbon fuels that within which detonation observed, the detonation sensitive of the mixtures in increasing order are obtained as following: p-Xylene/H2/air, p-Xylene/C3H8/air and p-Xylene/C2H4/air. The results also indicate the relative ease that p-Xylene/gaseous hydrocarbon fuel/air can be detonated mainly depends on the detonation sensitive of the gaseous fuel, which is supported by the critical energy of direct detonation initiation and chemical kinetic analysis.

Isotope shift in the electron affinity of lithium  

SciTech Connect

Very accurate electron affinity (EA) calculations of {sup 6}Li and {sup 7}Li (and {sup {infinity}L}i) have been performed using explicitly correlated Gaussian functions and a variational approach that explicitly includes the nuclear motion in the calculations (i.e., the approach that does not assume the Born-Oppenheimer approximation). The leading relativistic and quantum electrodynamics corrections to the electron affinities were also calculated. The results are the most accurate theoretical values obtained for the studied systems to date. Our best estimates of the {sup 7}Li and {sup 6}Li EAs are 4984.9842(30) and 4984.9015(30) cm{sup -1}, respectively, and of the {sup 7}Li/{sup 6}Li EA isotope shift is 0.0827 cm{sup -1}.

Isotope shift in the sulfur electron affinity: Observation and theory  

SciTech Connect

The sulfur electron affinities {sup e}A(S) are measured by photodetachment microscopy for the two isotopes {sup 32}S and {sup 34}S (16 752.975 3(41) and 16 752.977 6(85) cm{sup -1}, respectively). The isotope shift in the electron affinity is found to be more probably positive, {sup e}A({sup 34}S)- {sup e}A({sup 32}S) =+0.0023(70) cm{sup -1}, but the uncertainty allows for the possibility that it may be either ''normal''[{sup e}A({sup 34}S) > {sup e}A({sup 32}S)] or ''anomalous''[{sup e}A({sup 34}S) < {sup e}A({sup 32}S)]. The isotope shift is estimated theoretically using elaborate correlation models, monitoring the electron affinity and the mass polarization term expectation value. The theoretical analysis predicts a very large specific mass shift (SMS) that counterbalances the normal mass shift (NMS) and produces an anomalous isotope shift {sup e}A({sup 34}S)- {sup e}A({sup 32}S) =-0.0053(24) cm{sup -1}, field shift corrections included. The total isotope shift can always be written as the sum of the NMS (here +0.0169 cm{sup -1}) and a residual isotope shift (RIS). Since the NMS has nearly no uncertainty, the comparison between experimental and theoretical RIS is more fair. With respective values of -0.0146(70) cm{sup -1} and -0.0222(24) cm{sup -1}, these residual isotope shifts are found to agree within the estimated uncertainties.

RTT realization of quantum affine superalgebras and tensor products  

E-Print Network (OSTI)

We use the RTT realization of the quantum affine superalgebra associated with the Lie superalgebra $\\mathfrak{gl}(M,N)$ to study its finite-dimensional representations and their tensor products. In the case $\\mathfrak{gl}(1,1)$, the cyclicity condition of tensor products of finite-dimensional simple modules is determined completely in terms of zeros and poles of rational functions. This in turn induces cyclicity of some particular tensor products of Kirillov-Reshetikhin modules related to $\\mathfrak{gl}(M,N)$.

Affine Jordan cells, logarithmic correlators, and hamiltonian reduction  

E-Print Network (OSTI)

We study a particular type of logarithmic extension of SL(2,R) Wess-Zumino-Witten models. It is based on the introduction of affine Jordan cells constructed as multiplets of quasi-primary fields organized in indecomposable representations of the Lie algebra sl(2). We solve the simultaneously imposed set of conformal and SL(2,R) Ward identities for two- and three-point chiral blocks. These correlators will in general involve logarithmic terms and may be represented compactly by considering spins with nilpotent parts. The chiral blocks are found to exhibit hierarchical structures revealed by computing derivatives with respect to the spins. We modify the Knizhnik-Zamolodchikov equations to cover affine Jordan cells and show that our chiral blocks satisfy these equations. It is also demonstrated that a simple and well-established prescription for hamiltonian reduction at the level of ordinary correlators extends straightforwardly to the logarithmic correlators as the latter then reduce to the known results for two- and three-point conformal blocks in logarithmic conformal field theory.

Risk assessment of gaseous emissions from municipal solid waste landfill: case study Rafah landfill, Palestine  

Science Journals Connector (OSTI)

This article describes the risk assessment of gaseous emissions from the municipal solid waste at Rafah landfill, Palestine. In this study, Gas-Sim model was used to quantify the gaseous emissions from the landfill and the Land-Gem model was used to verify the results. Risk assessment of both carcinogens and non-carcinogens were performed. Two scenarios were conducted namely with plant uptake and without plant uptake. The scenario with plant uptake revealed that the risk to residents is acceptable for non-carcinogens (risk value 0.45 > 1.0), while the risk to residents is not acceptable for carcinogens (risk value 2.69 × 10?6 risk to residents is acceptable for non-carcinogens (risk value 0.42 > 1.0), while the risk to residents is acceptable for carcinogens (risk value 2.855 × 10?7 > 10?6).

Computational and theoretical analysis of weak and strong transverse-wave structures in gaseous detonations  

SciTech Connect

Two-dimensional simulation results are presented that capture at great detail the temporal evolution of Mach reflection triple point sub-structures intrinsic to gaseous detonation waves. The observed patterns are classified by shock polar analysis for realistic, thermally perfect but nonreactive gases. A diagram of the transition boundaries between possible Mach reflection structures is constructed and found to be in good agreement with the computational results.

Method and apparatus for the selective separation of gaseous coal gasification products by pressure swing adsorption  

SciTech Connect

Bulk separation of the gaseous components of multi-component gases provided by the gasification of coal including hydrogen, carbon monoxide, methane, and acid gases (carbon dioxide plus hydrogen sulfide) are selectively adsorbed by a pressure swing adsorption technique using activated carbon, zeolite or a combination thereof as the adsorbent. By charging a column containing the adsorbent with a gas mixture and pressurizing the column to a pressure sufficient to cause the adsorption of the gases and then reducing the partial pressure of the contents of the column, the gases are selectively and sequentially desorbed. Hydrogen, the least absorbable gas of the gaseous mixture, is the first gas to be desorbed and is removed from the column in a co-current direction followed by the carbon monoxide, hydrogen and methane. With the pressure in the column reduced to about atmospheric pressure the column is evacuated in a countercurrent direction to remove the acid gases from the column. The present invention is particularly advantageous as a producer of high parity hydrogen from gaseous products of coal gasification and as an acid gas scrubber.

MICROSTRUCTURE AND MECHANICAL PROPERTY PERFORMANCE OF COMMERCIAL GRADE API PIPELINE STEELS IN HIGH PRESSURE GASEOUS HYDROGEN  

SciTech Connect

The continued growth of the world s developing countries has placed an ever increasing demand on traditional fossil fuel energy sources. This development has lead to increasing research and development of alternative energy sources. Hydrogen gas is one of the potential alternative energy sources under development. Currently the most economical method of transporting large quantities of hydrogen gas is through steel pipelines. It is well known that hydrogen embrittlement has the potential to degrade steel s mechanical properties when hydrogen migrates into the steel matrix. Consequently, the current pipeline infrastructure used in hydrogen transport is typically operated in a conservative fashion. This operational practice is not conducive to economical movement of significant volumes of hydrogen gas as an alternative to fossil fuels. The degradation of the mechanical properties of steels in hydrogen service is known to depend on the microstructure of the steel. Understanding the levels of mechanical property degradation of a given microstructure when exposed to hydrogen gas under pressure can be used to evaluate the suitability of the existing pipeline infrastructure for hydrogen service and guide alloy and microstructure design for new hydrogen pipeline infrastructure. To this end, the 2 Copyright 2010 by ASME microstructures of relevant steels and their mechanical properties in relevant gaseous hydrogen environments must be fully characterized to establish suitability for transporting hydrogen. A project to evaluate four commercially available pipeline steels alloy/microstructure performance in the presences of gaseous hydrogen has been funded by the US Department of Energy along with the private sector. The microstructures of four pipeline steels were characterized and then tensile testing was conducted in gaseous hydrogen and helium at pressures of 800, 1600 and 3000 psi. Based on measurements of reduction of area, two of the four steels that performed the best across the pressure range were selected for evaluation of fracture and fatigue performance in gaseous hydrogen at 800 and 3000 psi. This paper will describe the work performed on four commercially available pipeline steels in the presence of gaseous hydrogen at pressures relevant for transport in pipelines. Microstructures and mechanical property performances will be compared. In addition, recommendations for future work related to gaining a better understanding of steel pipeline performance in hydrogen service will be discussed.

Magnetic Affinity Immunoassay Based Enzyme-labeled Phage Displayed Antibody  

Science Journals Connector (OSTI)

Abstract A novel magnetic affinity immunoassay (MAIA) strategy on the basis of enzyme-labeled phage displayed antibody was developed. The assay consisted of a sandwich format in which immobilized polyclonal antibody (pcAb) on magnetic microparticle was used as capture probe, and enzyme-labeled phage displayed antibody as specific detection probe to increase enzyme amount and enhance detection signal. By the proposed method, ?-bungarotoxin (?-BGT) was successfully detected. A linear relationship between absorbance value and the concentration of ?-BGT in the range of 0.016–62.5 ?g L?1 was obtained. The linear regression equation was Y = 0.641X + 1.355 (R = 0.9925, n = 13, p < 0.0001) with a detection limit of 0.016 ?g L?1. In comparison with the traditional ELISA, this method provided a 10-fold better sensitivity in ?-BGT detection. Also this method provided a 4-fold better sensitivity comparing with the MAIA based on enzyme labeled monoclonal antibody (mcAb). Due to the low detection limit, high accuracy and specificity, this method holds great promise in toxin trace detection.

Interchangeability of gaseous fuels - The importance of the Wobbe-index  

SciTech Connect

The Wobbe-index is introduced as an important gas quality criterion when interchanging gaseous fuels for engines. Changes in fuel gas composition appear not to induce noticeable changes in air to fuel ratio and combustion velocity when the Wobbe-index remains the same. This implies that no re-adjustment of ignition timing and air to fuel ratio settings is required, then. The volumetric energy content, the explosion limits and the knock resistance of a mixture can vary to a moderate extent when the Wobbe-index is constant and the gas composition varies.

Replacement of chlorofluorocarbons (CFCs) at the DOE gaseous diffusion plants: An assessment of global impacts  

SciTech Connect

The US Department of Energy (DOE) formerly operated two gaseous diffusion plants (GDPs) for enriching uranium and maintained a third shutdown GDP. These plants maintain a large inventory of dichlorotetrafluorethane (CFC-114), a cholorofluorocarbon (CFC), as a coolant. The paper evaluates the global impacts of four alternatives to modify GDP coolant system operations for a three-year period beginning in 1996. Interim modification of GDP coolant system operations has the potential to reduce stratospheric ozone depletion from GDP coolant releases while a permanent solution is studied.

High-temperature sorbent method for removal of sulfur containing gases from gaseous mixtures  

DOE Patents (OSTI)

A copper oxide-zinc oxide mixture is used as a sorbent for removing hydrogen sulfide and other sulfur containing gases at high temperatures from a gaseous fuel mixture. This high-temperature sorbent is especially useful for preparing fuel gases for high temperature fuel cells. The copper oxide is initially reduced in a preconditioning step to elemental copper and is present in a highly dispersed state throughout the zinc oxide which serves as a support as well as adding to the sulfur sorption capacity. The spent sorbent is regenerated by high-temperature treatment with an air fuel, air steam mixture followed by hydrogen reduction to remove and recover the sulfur.

Liquefied Gaseous Fuels Safety and Environmental Control Assessment Program: second status report  

SciTech Connect

The Assistant Secretary for Environment has responsibility for identifying, characterizing, and ameliorating the environmental, health, and safety issues and public concerns associated with commercial operation of specific energy systems. The need for developing a safety and environmental control assessment for liquefied gaseous fuels was identified by the Environmental and Safety Engineering Division as a result of discussions with various governmental, industry, and academic persons having expertise with respect to the particular materials involved: liquefied natural gas, liquefied petroleum gas, hydrogen, and anhydrous ammonia. This document is arranged in three volumes and reports on progress in the Liquefied Gaseous Fuels (LGF) Safety and Environmental Control Assessment Program made in Fiscal Year (FY)-1979 and early FY-1980. Volume 1 (Executive Summary) describes the background, purpose and organization of the LGF Program and contains summaries of the 25 reports presented in Volumes 2 and 3. Annotated bibliographies on Liquefied Natural Gas (LNG) Safety and Environmental Control Research and on Fire Safety and Hazards of Liquefied Petroleum Gas (LPG) are included in Volume 1.

Development of NF3 Deposit Removal Technology for the Portsmouth Gaseous Diffusion Plant  

SciTech Connect

This paper summarizes the Battelle, Stoller, and WASTREN (BSW) team's efforts, to date, in support of the United States Department of Energy's plans to remove uranium and technetium deposits before decommissioning the Portsmouth Gaseous Diffusion Plant. The BSW team investigated nitrogen trifluoride (NF{sub 3}) as a safer yet effective alternative gaseous treatment to the chlorine trifluoride (ClF{sub 3})-elemental fluorine (F{sub 2}) treatment currently used to remove uranium and technetium deposits from the uranium enrichment cascade. Both ClF{sub 3} and F{sub 2} are highly reactive, toxic, and hazardous gases, while NF{sub 3}, although toxic [1], is no more harmful than moth balls [2]. BSW's laboratory thermo-analytical and laboratory-scale prototype studies with NF{sub 3} established that thermal NF{sub 3} can effectively remove likely and potential uranium (UO{sub 2}F{sub 2} and UF{sub 4}) and technetium deposits (a surrogate deposit material, TcO{sub 2}, and pertechnetates) by conversion to volatile compounds. Our engineering evaluations suggest that NF{sub 3}'s effectiveness could be enhanced by combining with a lesser concentration of ClF{sub 3}. BSW's and other's studies indicate compatibility with Portsmouth materials of construction (aluminum, copper, and nickel). (authors)

Using large environmental chamber technique for gaseous contaminant removal equipment test  

SciTech Connect

The US Association of Home Appliance Manufacturers (AHAM) has set a voluntary standard for testing the initial dust-removal capacity of portable air cleaners. In the authors` test of portable air cleaners for the local consumer council, the AHAM method was extended to test the initial removal capacity for gaseous phase pollutants. Also, carbon filters` efficiency change over time in toluene removal on a number of air cleaners was tested. In using a large chamber to carry out these tests, the chamber wall adsorption and re-emission effects were experimentally quantified. These tests indicated that a large chamber, with its wall surface adsorption controlled, is simple and robust to use to quantify the initial cleaning capacity for gaseous phase pollutants. Based on these test results, a large chamber method is proposed to test the performance lifetimes of portable air cleaners. The system advantages of the method over the in-duct performance life test methods are that no continuous air-cleaning system is required and that the chamber`s humidity and temperature can be maintained at the desired values more easily with the combination of a unitary dehumidifier and a bubbler system. This paper will present the trial results with portable air cleaner tests and discuss the large environmental chamber techniques.

Laboratory scale studies on gaseous emissions generated by the incineration of an artificial automotive shredder residue presenting a critical composition  

Science Journals Connector (OSTI)

Car manufacturers must eliminate automotive shredder residues (ASR). Two ways of incineration are of interest: at 850°C in municipal waste incinerators or at higher temperatures, above 1100°C in cement plants. These processes reduce the mass and the volume of waste to be disposed of in landfills and energy recovery might be possible. Regulations govern the emission of gaseous effluents to control environmental risk. To determine gaseous effluents from a pilot sacle or an industrial incineration plant, an artificial ASR was made by mixing three representative organic polymers present in the real ASR, namely polyvinylchloride, polyurethane and rubber. This mixture was incinerated at 850 and 1100°C in laboratory experiments and the analyses of the principal gaseous effluents such as carbon oxides, nitrogen oxides, volatile organic compounds, hydrochloric and hydrocyanic acids and sulphur compounds are presented and discussed. Lastly, in order to simulate artificial ASR behaviour, the composition of the combustion gases at equilibrium was calculated using a Gibbs energy minimisation code.

Method and system for low-NO.sub.x dual-fuel combustion of liquid and/or gaseous fuels  

SciTech Connect

A method and apparatus for combustion in which a pressurized preheated liquid fuel is atomized and a portion thereof flash vaporized, creating a mixture of fuel vapor and liquid droplets. The mixture is mixed with primary combustion oxidant, producing a fuel/primary oxidant mixture which is then injected into a primary combustion chamber in which the fuel/primary oxidant mixture is partially combusted, producing a secondary gaseous fuel containing hydrogen and carbon oxides. The secondary gaseous fuel is mixed with a secondary combustion oxidant and injected into the second combustion chamber wherein complete combustion of the secondary gaseous fuel is carried out. The resulting second stage flue gas containing very low amounts of NO.sub.x is then vented from the second combustion chamber.

Apparatus and method for operating internal combustion engines from variable mixtures of gaseous fuels  

DOE Patents (OSTI)

An apparatus and method for utilizing any arbitrary mixture ratio of multiple fuel gases having differing combustion characteristics, such as natural gas and hydrogen gas, within an internal combustion engine. The gaseous fuel composition ratio is first sensed, such as by thermal conductivity, infrared signature, sound propagation speed, or equivalent mixture differentiation mechanisms and combinations thereof which are utilized as input(s) to a "multiple map" engine control module which modulates selected operating parameters of the engine, such as fuel injection and ignition timing, in response to the proportions of fuel gases available so that the engine operates correctly and at high efficiency irrespective of the gas mixture ratio being utilized. As a result, an engine configured according to the teachings of the present invention may be fueled from at least two different fuel sources without admixing constraints.

Privatization of the gaseous diffusion plants and impacts on nuclear criticality safety administration  

SciTech Connect

The Energy Policy Act of 1992 created the United States Enrichment Corporation (USEC) on July 1, 1993. The USEC is a government-owned business that leases those Gaseous Diffusion Plant (GDP) facilities at the Portsmouth, Ohio, and Paducah, Kentucky, sites from the U.S. Department of Energy (DOE) that are required for enriching uranium. Lockheed Martin Utility Services is the operating contractor for the USEC-leased facilities. The DOE has retained use of, and regulation over, some facilities and areas at the Portsmouth and Paducah sites for managing legacy wastes and environmental restoration activities. The USEC is regulated by the DOE, but is currently changing to regulation under the U.S. Nuclear Regulatory Commission (NRC). The USEC is also preparing for privatization of the uranium enrichment enterprise. These changes have significantly affected the nuclear criticality safety (NCS) programs at the sites.

Study of technetium uptake in vegetation in the vicinity of the Portsmouth Gaseous Diffusion Plant  

SciTech Connect

Technetium-99 was measured in vegetation and soil collected on and near the Portsmouth Gaseous Diffusion Plant to obtain an estimate of the soil-to-vegetation concentration factors. The concentration factors appear to be lognormally distributed with a geometric mean of 3.4 (Bq/kg dry wt. tissue per Bq/kg dry wt. soil) and a geometric standard deviation of 4.7. A dose commitment was calculated using a hypothetical 3.7 x 10/sup 10/ Bq Tc-99/year release and the actual CY-1981 concentration release of Tc-99. The radiological significance of Tc-99 in the terrestial food chain is substantially less than previously believed.

Gusty, gaseous flows of FIRE: galactic winds in cosmological simulations with explicit stellar feedback  

E-Print Network (OSTI)

We present an analysis of the galaxy-scale gaseous outflows from the FIRE (Feedback in Realistic Environments) simulations. This suite of hydrodynamic cosmological zoom simulations provides a sample of halos where star-forming giant molecular clouds are resolved to z=0, and features an explicit stellar feedback model on small scales. In this work, we focus on quantifying the gas mass ejected out of galaxies in winds and how this material travels through the halo. We correlate these quantities to star formation in galaxies throughout cosmic history. Our simulations reveal that a significant portion of every galaxy's evolution, particularly at high redshift, is dominated by bursts of star formation, which are followed by powerful gusts of galactic outflow that sweep up a large fraction of gas in the interstellar medium and send it through the circumgalactic medium. The dynamical effect of these outflows can significantly limit the amount of star formation within the affected galaxy. At low redshift, however, su...

A probabilistic safety analysis of UF{sub 6} handling at the Portsmouth Gaseous Diffusion Plant  

SciTech Connect

A probabilistic safety study of UF{sub 6} handling activities at the Portsmouth Gaseous Diffusion Plant has recently been completed. The analysis provides a unique perspective on the safety of UF{sub 6} handling activities. The estimated release frequencies provide an understanding of current risks, and the examination of individual contributors yields a ranking of important plant features and operations. Aside from the probabilistic results, however, there is an even more important benefit derived from a systematic modeling of all operations. The integrated approach employed in the analysis allows the interrelationships among the equipment and the required operations to be explored in depth. This paper summarizes the methods used in the study and provides an overview of some of the technical insights that were obtained. Specific areas of possible improvement in operations are described.

Purex Plant gaseous iodine-129 control capability and process development requirements  

SciTech Connect

This report describes the ability of the Purex Plant to effectively control iodine-129 emissions. Based on historical evidence, the current Purex Plant iodine control system appears capable of meeting the goal of limiting gaseous iodine-129 emissions at the point of discharge to levels stipulated by the Department of Energy (DOE) for an uncontrolled area. Expected decontamination factors (DF`s) with the current system will average about 100 and will be above the calculated DF`s of 2.2 and 87 required to meet DOE yearly average concentration limits for controlled and uncontrolled areas respectively, but below the calculated DF of 352 required for meeting the proposed Environmental Protection Agency (EPA) mass emission limit. Chemical costs for maintaining compliance with the DOE limits will be approximately $166 per metric ton of fuel processed (based on a silver nitrate price of $12.38/oz). Costs will increase in proportion to increases in silver prices.

Constraints on the microwave opacity of gaseous methane and water vapor in the Jovian atmosphere  

SciTech Connect

Gaseous NH/sub 3/'s microwave absorption in the Jovian atmosphere appears too great to be due to a solar abundance of this gas. The additional capacity of microwave absorption is presently sought in measurements of the microwave absorption of CH/sub 4/ and H/sub 2/O under simulated Jovian conditions at 2.25 GHz, 8.5 GHz, 21.7 GHz; due to large error bars, measurements represent upper limits on the microwave opacity generated by H/sub 2/O and CH/sub 4/. The results obtained are consistent with theoretical expressions for microwave opacity in a Jovian atmosphere at the specified frequencies. The presence of an NH/sub 3/ abundance exceeding the solar level by a factor of 1.5 is indicated by test results. 16 references.

The performance and the gaseous emissions of two small marine craft diesel engines fuelled with biodiesel  

Science Journals Connector (OSTI)

An experimental investigation of the application of biodiesel (recycled cooking fat and vegetable oil) on small marine craft diesel engines was completed. The tests were performed on Perkins 404C-22 (Marinised) in Boat No. 1 (Fair Countess) and on Nanni Diesel 3.100HE in Boat No. 2 (Aimee 2). The tests were designed and carried out in accordance with the standardised test procedure described in ISO 8178-4 Test Cycle E5. The performance and gaseous emissions of the tested engines were compared and analysed. The test results show that the power output for both trial engines operating with biodiesel were comparable to that fuelled with fossil diesel, but with an increase in fuel consumptions. The \\{NOx\\} emissions were found to be reduced when fuelled with biodiesel. The CO emissions were found to be lower when the engines operated at higher loads using biodiesel.

Development of a cold-neutron imaging detector based on thick gaseous electron multiplier  

SciTech Connect

We present the results of our recent studies on a cold-neutron imaging detector prototype based on THick Gaseous Electron Multiplier (THGEM). The detector consists of a thin Boron layer, for neutron-to-charged particle conversion, coupled to two THGEM electrodes in cascade for charge amplification and a position-sensitive charge-readout anode. The detector operates in Ne/(5%)CF{sub 4}, at atmospheric pressure, in a stable condition at a gain of around 10{sup 4}. Due to the geometrical structure of the detector elements (THGEM geometry and charge read-out anode), the image of detector active area shows a large inhomogeneity, corrected using a dedicated flat-filed correction algorithm. The prototype provides a detection efficiency of 5% and an effective spatial resolution of the order of 1.3 mm.

Apparatus for recovering gaseous hydrocarbons from hydrocarbon-containing solid hydrates  

DOE Patents (OSTI)

A method and apparatus are provided for producing gaseous hydrocarbons from formations comprising solid hydrocarbon hydrates located under either a body of land or a body of water. The vast natural resources of such hydrocarbon hydrates can thus now be economically mined. Relatively warm brine or water is brought down from an elevation above that of the hydrates through a portion of the apparatus and passes in contact with the hydrates, thus melting them. The liquid then continues up another portion of the apparatus, carrying entrained hydrocarbon vapors in the form of bubbles, which can easily be separated from the liquid. After a short startup procedure, the process and apparatus are substantially self-powered.

Shaping of fuel delivery characteristics for solenoid operated diesel engine gaseous injectors  

SciTech Connect

Solenoid operated gaseous injectors, when compared to conventional liquid fuel diesel injectors, differ in the way the fuel dose and its discharge rate are controlled. While in conventional diesel systems, the fuel dose and its injection rate depends on the fuel injection pump effective stroke and on the plunger diameter and velocity, the solenoid injectors operate in an on-off manner which limits the ability to control the gas discharge rate, resulting in its profile to be basically rectangular in shape. To reduce the gas injection rate at the beginning of the injection process in order to suppress the diesel-knock phenomenon, similar procedures as used in diesel engines could be implemented. One such approach is to use a throttling type pintle nozzle, and another method is to use a double-spring injector with a hole nozzle. The rationale for using such nozzle configurations is that gaseous fuels do not require atomization, and therefore, can be injected at lower discharge velocities than with liquid fuels. The gas delivery characteristics from a solenoid injector has been computer-simulated in order to assess the impact of the investigated three modes of fuel discharge rate control strategies. The simulation results confirmed that the gas dose and its discharge rate can be shaped as required. An experimental set-up is described to measure the gas discharge rate using a special gas injection mass flow rate indicator with a strain-gage sensor installed at the entry to a long tube, similar to that proposed by Bosch for liquid fuel volumetric flow rate measurements.

Inverted end-Hall-type low-energy high-current gaseous ion source  

SciTech Connect

A novel approach to low-energy, high-current, gaseous ion beam generation was explored and an ion source based on this technique has been developed. The source utilizes a dc high-current (up to 20 A) gaseous discharge with electron injection into the region of ion generation. Compared to the conventional end-Hall ion source, the locations of the discharge anode and cathode are inverted: the cathode is placed inside the source and the anode outside, and correspondingly, the discharge current is in the opposite direction. The discharge operates in a diverging axial magnetic field, similar to the end-Hall source. Electron generation and injection is accomplished by using an additional arc discharge with a ''cold'' (filamentless) hollow cathode. Low plasma contamination is achieved by using a low discharge voltage (avoidance of sputtering), as well as by a special geometric configuration of the emitter discharge electrodes, thereby filtering (removing) the erosion products stemming from the emitter cathode. The device produces a dc ion flow with energy below 20 eV and current up to 2.5 A onto a collector of 500 cm{sup 2} at 25 cm from the source edge, at a pressure {>=}0.02 Pa and gas flow rate {>=}14 SCCM. The ion energy spread is 2 to 3 eV (rms). The source is characterized by high reliability, low maintenance, and long lifetime. The beam contains less than 0.1% of metallic ions. The specific electric energy consumption is 400 eV per ion registered at the collector. The source operates with noble gases, nitrogen, oxygen, and hydrocarbons. Utilizing biasing, it can be used for plasma sputtering, etching, and other ion technologies.

Reduction of particulate matter and gaseous emission from marine diesel engines using a catalyzed particulate filter  

Science Journals Connector (OSTI)

Diesel engines are used widely as the power sources of coastal ships and international vessels primarily due to their high thermal efficiency, high fuel economy and durable performance. However, the gaseous and solid substances exhausted from diesel engines during the combustion process cause air pollution, in particular around harbor regions. In order to effectively reduce particulate matter and gaseous pollution emissions, a catalyzed particulate filter was equipped in the tail pipe of a marine diesel engine. The engine's performance and emission characteristics under various engine speeds and torques were measured using a computerized engine data control and acquisition system accompanied with an engine dynamometer. The effectiveness of installing a catalyzed particulate filter on the reduction of pollutant emissions was examined. The experimental results show that the exhaust gas temperature, carbon monoxide and smoke opacity were reduced significantly upon installation of the particulate filter. In particular, larger conversion of carbon monoxide to carbon dioxide — and thus larger CO2 and lower CO emissions — were observed for the marine diesel engine equipped with a catalyzed particulate filter and operated at higher engine speeds. This is presumably due to enhancement of the catalytic oxidation reaction that results from an exhaust gas with stronger stirring motion passing through the filter. The absorption of partial heating energy from the exhaust gas by the physical structure of the particulate filter resulted in a reduction in the exhaust gas temperature. The particulate matter could be burnt to a greater extent due to the effect of the catalyst coated on the surface of the particulate filter. Moreover, the fuel consumption rate was increased slightly while the excess oxygen emission was somewhat decreased with the particulate filter.

Selective Gaseous Extraction: Research, Development and Training for Isotope Production, Final Technical Report  

SciTech Connect

General Atomics and the University of Missouri Research Reactor (MURR) completed research and development of selective gaseous extraction of fission products from irradiated fuel, which included training and education of MURR students. The process used porous fuel and after irradiation flowed product gases through the fuel to selectively removed desired fission products with the primary goal of demonstrating the removal of rhodium 105. High removal rates for the ruthenium/rhodium (Ru/Rh), tellurium/iodine (Te/I) and molybdenum/technetium (Mo/Tc) series were demonstrated. The success of this research provides for the reuse of the target for further production, significantly reducing the production of actinide wastes relative to processes that dissolve the target. This effort was conducted under DOE funding (DE-SC0007772). General Atomics objective of the project was to conduct R&D on alternative methods to produce a number of radioactive isotopes currently needed for medical and industry applications to include rhodium-105 and other useful isotopes. Selective gaseous extraction was shown to be effective at removing radioisotopes of the ruthenium/rhodium, tellurium/iodine and molybdenum/technetium decay chains while having trace to no quantities of other fission products or actinides. This adds a new, credible method to the area of certain commercial isotope production beyond current techniques, while providing significant potential reduction of process wastes. Waste reduction, along with reduced processing time/cost provides for superior economic feasibility which may allow domestic production under full cost recovery practices. This provides the potential for improved access to domestically produced isotopes for medical diagnostics and treatment at reduced cost, providing for the public good.

Quantum dynamics and state-dependent affine gauge fields on CP(N-1)  

E-Print Network (OSTI)

Gauge fields frequently used as an independent construction additional to so-called wave fields of matter. This artificial separation is of course useful in some applications (like Berry's interactions between the "heavy" and "light" sub-systems) but it is restrictive on the fundamental level of "elementary" particles and entangled states. It is shown that the linear superposition of action states and non-linear dynamics of the local dynamical variables form an oscillons of energy representing non-local particles - "lumps" arising together with their "affine gauge potential" agrees with Fubini-Study metric. I use the conservation laws of local dynamical variables (LDV's) during affine parallel transport in complex projective Hilbert space $CP(N-1)$ for twofold aim. Firstly, I formulate the variation problem for the ``affine gauge potential" as system of partial differential equations \\cite{Le1}. Their solutions provide embedding quantum dynamics into dynamical space-time whose state-dependent coordinates related to the qubit spinor subjected to Lorentz transformations of "quantum boosts" and "quantum rotations". Thereby, the problem of quantum measurement being reformulated as the comparison of LDV's during their affine parallel transport in $CP(N-1)$, is inherently connected with space-time emergences. Secondly, the important application of these fields is the completeness of quantum theory. The EPR and Schr\\"odinger's Cat paradoxes are discussed from the point of view of the restored Lorentz invariance due to the affine parallel transport of local Hamiltonian of the soliton-like field.

Fusion rules and complete reducibility of certain modules for affine Lie algebras  

E-Print Network (OSTI)

We develop a new method for obtaining branching rules for affine Kac-Moody Lie algebras at negative integer levels. This method uses fusion rules for vertex operator algebras of affine type. We prove that an infinite family of ordinary modules for affine vertex algebra of type A investigated in Adamovi\\'c and O. Per\\v{s}e (2008) is closed under fusion. Then we apply these fusion rules on explicit bosonic realization of level -1 modules for the affine Lie algebra of type $A_{\\ell-1}^{(1)}$, obtain a new proof of complete reducibility for these representations, and the corresponding decomposition for $\\ell \\ge 3$. We also obtain the complete reducibility of the associated level -1 modules for affine Lie algebra of type $C_{\\ell}^{(1)}$. Next we notice that the category of $D_{2 \\ell -1}^{(1)}$ modules at level $- 2 \\ell +3 $ obtained in Per\\v{s}e (2012) has the isomorphic fusion algebra. This enables us to decompose certain $E_6 ^{(1)}$ and $F_4 ^{(1)}$--modules at negative levels.

A Direct Error Measure for Affine Models of Nonlinear Algebraic Systems

A Direct Error Measure for Affine Models of Nonlinear Algebraic Systems A Direct Error Measure for Affine Models of Nonlinear Algebraic Systems Speaker(s): David Lorenzetti Date: June 2, 1999 - 12:00pm Location: Bldg. 90 The Newton-Raphson solution of a nonlinear system iterately linearizes the equations, then steps to the solution of the resulting affine model. When a step exceeds the predictive range of its model, the method can diverge. The traditional response -- aggregating the equations into a cost function, and applying a minimization method -- suppresses information about how each equation model performs. Direct error measures examine the equations individually, allowing finer control over step lengths. The seminar will develop one such measure through the geometry of simple one- and two-dimensional examples, then present results from a suite of larger

Hopping in the Phase Model to a Non-Commutative Verlinde Formula for Affine Fusion  

E-Print Network (OSTI)

Korff and Stroppel discovered a realization of su(n) affine fusion, the fusion of the su(n) Wess-Zumino-Novikov-Witten (WZNW) conformal field theory, in the phase model, a limit of the q-boson hopping model. This integrable-model realization provides a new perspective on affine fusion, explored in a recent paper by the author. The role of WZNW primary fields is played in it by non-commutative Schur polynomials, and fusion coefficients are thus given by a non-commutative version of the Verlinde formula. We present the extension to all Verlinde dimensions, of arbitrary genus and any number N of points. The level-dependence of affine fusion is also discussed, using the concept of threshold level, and its generalization to threshold weight.

Sorption affinities of sulfamethoxazole and carbamazepine to two sorbents under co-sorption systems  

Science Journals Connector (OSTI)

Abstract The Kd of sulfamethoxazole (SMX) on activated carbon (AC) was larger than that of SMX on single-walled carbon nanotubes (SC), but the competition of SMX with carbamazepine (CBZ) for adsorption sites was weaker on AC than SC. Thus, a large Kd value does not necessarily reflect a high affinity. The analysis of the apparent sorption, competition, desorption hysteresis, and the sorption thermodynamics for SMX and CBZ did not provide sufficient information to distinguish their sorption affinities. The release of the adsorbed CBZ was not altered with SMX as the competitor, but SMX release increased significantly after CBZ addition. The higher sorption affinity of CBZ may be explained by the interactions of the CBZ benzene rings with the aromatic structures of the adsorbents. Although the thermodynamic meaning cannot be described, the release ratio of the adsorbed pollutants provides useful information for understanding pollutant sorption strength and associated risks.

Molecular mechanism of bundle formation by the bacterial actin ParM  

SciTech Connect

The actin homolog ParM plays a microtubule-like role in segregating DNA prior to bacterial cell division. Fluorescence and cryo-electron microscopy have shown that ParM forms filament bundles between separating DNA plasmids in vivo. Given the lack of ParM bundling proteins it remains unknown how ParM bundles form at the molecular level. Here we show using time-lapse TIRF microscopy, under in vitro molecular crowding conditions, that ParM-bundle formation consists of two distinct phases. At the onset of polymerization bundle thickness and shape are determined in the form of nuclei of short helically disordered filaments arranged in a liquid-like lattice. These nuclei then undergo an elongation phase whereby they rapidly increase in length. At steady state, ParM bundles fuse into one single large aggregate. This behavior had been predicted by theory but has not been observed for any other cytomotive biopolymer, including F-actin. We employed electron micrographs of ParM rafts, which are 2-D analogs of 3-D bundles, to identify the main molecular interfilament contacts within these suprastructures. The interface between filaments is similar for both parallel and anti-parallel orientations and the distribution of filament polarity is random within a bundle. We suggest that the interfilament interactions are not due to the interactions of specific residues but rather to long-range, counter ion mediated, electrostatic attractive forces. A randomly oriented bundle ensures that the assembly is rigid and that DNA may be captured with equal efficiency at both ends of the bundle via the ParR binding protein.

Decay Energies of Gaseous Fission Products and their Daughters for A=88 to 93  

Science Journals Connector (OSTI)

A systematic study of ?-decay energies has been made for mass-separated activities of Kr gaseous fission products and their daughters at the TRISTAN on-line separator facility at the Ames Laboratory research reactor. A well-type plastic scintillator was used in coincidence with a Ge(Li) ? detector to determine ?-group end-point energies and deduce Q values. The following ?-decay energies have been determined: Kr88, 2.93 ± 0.03 MeV; Rb88, 5.30 ± 0.06 MeV; Kr89, 4.93 ± 0.06 MeV; Kr90, 4.35 ± 0.05 MeV; Rb90, 6.32 ± 0.07 MeV; Kr91, 6.12 ± 0.07 MeV; Rb91, 5.68 ± 0.04 MeV; Kr92, 5.97 ± 0.08 MeV; Rb92, 7.58 ± 0.15 MeV; Sr92, 1.93 ± 0.03 MeV; Kr93, 8.3 ± 0.5 MeV; and Rb93, 7.23 ± 0.10 MeV. The decay energies are compared with previous measurements, systematics predictions, and two currently accepted mass relations. The energies are used to predict the ?-decay energies for 13 additional nuclei by means of systematics.

Safeguards Verification Measurements using Laser Ablation, Absorbance Ratio Spectrometry in Gaseous Centrifuge Enrichment Plants  

SciTech Connect

Laser Ablation Absorbance Ratio Spectrometry (LAARS) is a new verification measurement technology under development at the US Department of Energy (DOE) Pacific Northwest National Laboratory (PNNL). LAARS uses three lasers to ablate and then measure the relative isotopic abundance of uranium compounds. An ablation laser is tightly focused on uranium-bearing solids, producing a small atomic uranium vapor plume. Two collinear wavelength-tuned spectrometry lasers transit through the plume and the absorbance of U-235 and U-238 isotopes are measured to determine U-235 enrichment. The measurement is independent of chemical form and degree of dilution with nuisance dust and other materials. LAARS has high relative precision and detection limits approaching the femtogram range for U-235. The sample is scanned and assayed point-by-point at rates reaching 1 million measurements/hour, enabling LAARS to detect and analyze uranium in trace samples. The spectrometer is assembled using primarily commercially available components and features a compact design and automated analysis.Two specific gaseous centrifuge enrichment plant (GCEP) applications of the spectrometer are currently under development: 1) LAARS-Environmental Sampling (ES), which collects and analyzes aerosol particles for GCEP misuse detection and 2) LAARS-Destructive Assay (DA), which enables onsite enrichment DA sample collection and analysis for protracted diversion detection. The two applications propose game-changing technological advances in GCEP safeguards verification.

Modeling of temporal behavior of isotopic exchange between gaseous hydrogen and palladium hydride power  

SciTech Connect

A parametric rate-equation model is described which depicts the time dependent behavior of the isotopic exchange process occurring between the solid and gas phases in gaseous hydrogen (deuterium) flows through packed-powder palladium deuteride (hydride) beds. The exchange mechanism is assumed to be rate-limited by processes taking place on the surface of the powder. The fundamental kinetic parameter of the model is the isotopic exchange probability, p, which is the probability that an isotopic exchange event occurs during a collision of a gas phase atom with the surface. Isotope effects between the gas and solid phases are explicitly included in terms of the isotope separation factor, ..cap alpha... Results of the model are compared with recent experimental measurements of isotope exchange in the ..beta..-phase hydrogen/palladium system and, using a literature value of ..cap alpha.. = 2.4, a good description of the experimental data is obtained for p approx. 10/sup -7/. In view of the importance of the isotope effects in the hydrogen/palladium system and the range of ..cap alpha.. values reported for the ..beta..-phase in the literature, the sensitivity of the model results to a variation in the value of ..cap alpha.. is examined.

Gravitational drag on a point mass in hypersonic motion through a gaseous medium  

E-Print Network (OSTI)

We explore a ballistic orbit model to infer the gravitational drag force on an accreting point mass M, such as a black hole, moving at a hypersonic velocity v_{0} through a gaseous environment of density \\rho_{0}. The streamlines blend in the flow past the body and transfer momentum to it. The total drag force acting on the body, including the nonlinear contribution of those streamlines with small impact parameter that bend significantly and pass through a shock, can be calculated by imposing conservation of momentum. In this fully analytic approach, the ambiguity in the definition of the lower cut-off distance $r_{\\rm min}$ in calculations of the effect of dynamical friction is removed. It turns out that $r_{\\rm min}=\\sqrt{e}GM/2v_{0}^{2}$. Using spherical surfaces of control of different sizes, we carry out a successful comparison between the predicted drag force and the one obtained from a high resolution, axisymmetric, isothermal flow simulation. We demonstrate that ballistic models are reasonably success...

Analysis of gaseous-phase stable and radioactive isotopes in the unsaturated zone, Yucca Mountain, Nevada  

SciTech Connect

The Nevada Nuclear Waste Storage Investigations Project of the US Department of Energy provides that agency with data for evaluating volcanic tuff beneath Yucca Mountain, Nevada, to determine its suitability for a potential repository of high-level radioactive waste. Thickness of the unsaturated zone, which consists of fractured, welded and nonwelded tuff, is about 1640 to 2460 feet (500 to 750 meters). One question to be resolved is an estimate of minimum ground-water traveltime from the disturbed zone of the potentail repository to the accessible environment. Another issue is the potential for diffusive or convective gaseous transport of radionuclides from an underground facility in the unsaturated zone to the accessible environment. Gas samples were collected at intervals to a depth of 1200 feet from the unsaturated zone at Yucca Mountain, Nevada. Samples were analyzed for major atmospheric gases; carbon dioxide in the samples was analyzed for carbon-14 activity and for {delta}2!{sup 3}C; water vapor in the samples was analyzed for deuterium and oxygen-18. These data could provide insight into the nature of unsaturated zone transport processes. 15 refs., 4 figs., 4 tabs.

DYNAMICAL FRICTION IN A GASEOUS MEDIUM WITH A LARGE-SCALE MAGNETIC FIELD  

SciTech Connect

The dynamical friction force experienced by a massive gravitating body moving through a gaseous medium is modified by sufficiently strong large-scale magnetic fields. Using linear perturbation theory, we calculate the structure of the wake generated by, and the gravitational drag force on, a body traveling in a straight-line trajectory in a uniformly magnetized medium. The functional form of the drag force as a function of the Mach number ({identical_to} V{sub 0}/c{sub s} , where V{sub 0} is the velocity of the body and c{sub s} is the sound speed) depends on the strength of the magnetic field and on the angle between the velocity of the perturber and the direction of the magnetic field. In particular, the peak value of the drag force is not near Mach number {approx}1 for a perturber moving in a sufficiently magnetized medium. As a rule of thumb, we may state that for supersonic motion, magnetic fields act to suppress dynamical friction; for subsonic motion, they tend to enhance dynamical friction. For perturbers moving along the magnetic field lines, the drag force at some subsonic Mach numbers may be stronger than at supersonic velocities. We also mention the relevance of our findings to black hole coalescence in galactic nuclei.

308 nm photochemical reaction of gaseous HNO3 and benzene on ?-Fe2O3 surfaces  

Science Journals Connector (OSTI)

Abstract The 308 nm photochemical reactions of nitric acid (HNO3) and benzene in the gas phase and on ?-Fe2O3 surface at 298 K was investigated by using Fourier transform infrared spectroscopy (FT-IR) combined with high performance liquid chromatography (HPLC). The concentration and yield of HONO and p-nitrophenol (p-NP) had been examined as a function of reaction time, benzene initial concentration and relative humidity on photochemical reaction. The results showed that gaseous HNO3 did not directly react with benzene in the dark, and p-NP was formed irradiation under 308 nm UV light. When HNO3 initial concentration was 400 Pa and benzene was 300 Pa, the illumination time was 100 min, the concentration of p-NP produced from the photochemical reaction of HNO3 and benzene on ?-Fe2O3 surface was about 3.08 times higher than that in the gas phase. In the meantime, while reaction time was 40 min and relative humidity was 70%, the concentration of HONO and p-NP formed on ?-Fe2O3 surface were about 3.55 and 2.51 times higher than those in the gas phase, and the yield of p-NP was 3.74% and 2.99%, respectively. Surfaces effect played a leading role in photochemical reaction of HNO3 and benzene on ?-Fe2O3 surface.

Variable Emission from a Gaseous Disc around a Metal-Polluted White Dwarf  

E-Print Network (OSTI)

We present the discovery of strongly variable emission lines from a gaseous disc around the DA white dwarf SDSS J1617+1620, a star previously found to have an infrared excess indicative of a dusty debris disc formed by the tidal disruption of a rocky planetary body. Time-series spectroscopy obtained during the period 2006-2014 has shown the appearance of strong double-peaked Ca II emission lines in 2008. The lines were weak, at best, during earlier observations, and monotonically faded through the remainder of our monitoring. Our observations represent unambiguous evidence for short-term variability in the debris environment of evolved planetary systems. Possible explanations for this extraordinary variability include the impact onto the dusty disc of either a single small rocky planetesimal, or of material from a highly eccentric debris tail. The increase in flux from the emission lines is sufficient that similar events could be detected in the broadband photometry of ongoing and future large-area time domai...

Oak Ridge Gaseous Diffusion Plant Biological Monitoring and Abatement Program for Mitchell Branch  

SciTech Connect

A proposed Biological Monitoring and Abatement Program (BMAP) for the Oak Ridge Gaseous Diffusion Plant (ORGDP; currently the Oak Ridge K-25 Site) was prepared in December 1986, as required by the modified National Pollutant Discharge Elimination System (NPDES) permit that was issued on September 11, 1986. The effluent discharges to Mitchell Branch are complex, consisting of trace elements, organic chemicals, and radionuclides in addition to various conventional pollutants. Moreover, the composition of these effluent streams will be changing over time as various pollution abatement measures are implemented over the next several years. Although contaminant inputs to the stream originate primarily as point sources from existing plant operations, area sources, such as the classified burial grounds and the K-1407-C holding pond, can not be eliminated as potential sources of contaminants. The proposed BMAP consists of four tasks. These tasks include (1) ambient toxicity testing, (2) bioaccumulation studies, (3) biological indicator studies, and (4) ecological surveys of the benthic invertebrate and fish communities. BMAP will determine whether the effluent limits established for ORGDP protect the designated use of the receiving stream (Mitchell Branch) for growth and propagation of fish and aquatic life. Another objective of the program is to document the ecological effects resulting from various pollution abatement projects, such as the Central Neutralization Facility.

Determination of operating limits for radionuclides for a proposed landfill at Paducah Gaseous Diffusion Plant  

SciTech Connect

The operating limits for radionuclides in sanitary and industrial wastes were determined for a proposed landfill at the Paducah Gaseous Diffusion Plant (PGDP), Kentucky. These limits, which may be very small but nonzero, are not mandated by law or regulation but are needed for rational operation. The approach was based on analyses of the potential contamination of groundwater at the plant boundary and the potential exposure to radioactivity of an intruder at the landfill after closure. The groundwater analysis includes (1) a source model describing the disposal of waste and the release of radionuclides from waste to the groundwater, (2) site-specific groundwater flow and contaminant transport calculations, and (3) calculations of operating limits from the dose limit and conversion factors. The intruder analysis includes pathways through ingestion of contaminated vegetables and soil, external exposure to contaminated soil, and inhalation of suspended activity from contaminated soil particles. In both analyses, a limit on annual effective dose equivalent of 4 mrem (0.04 mSv) was adopted. The intended application of the results is to refine the radiological monitoring standards employed by the PGDP Health Physics personnel to determine what constitutes radioactive wastes, with concurrence of the Commonwealth of Kentucky.

Paducah Gaseous Diffusion Plant proposed pilot pump-and-treat project. Final report  

SciTech Connect

On March 23, 1992, R.C. Sleeman of the Department of Energy, Oak Ridge Operations Office requested that a Groundwater Corrective Actions Team be assembled to evaluate the technical merit of and the need to implement a proposed groundwater pump-and-treat demonstration project for the Northwest contaminant plume at the Paducah Gaseous Diffusion Plant. In addition to other suggestions, the Team recommended that further characterization data be obtained for the plume. In the Fall of 1993 additional, temporary well points were installed so that groundwater samples from the shallow groundwater system and the Regional Gravel Aquifer (RGA) could be obtained to provide a three-dimensional view of groundwater contamination in the region of the plume. The results indicate that pure-phase DNAPL (trichloroethylene [TCE]) probably are present in the source area of the plume and extend in depth to the base of the RGA. Because the DNAPL likely will represent a source of a dissolved phase plume for decades it is essential that source containment take place. The Team recommends that although effective hydraulic containment can be achieved, other alternatives should be considered. For example, recent advances in emplacing low permeability barrier walls to depths of 100 to 150 ft make it possible to consider encirclement of the source of the Northwest plume.

Operating limit study for the proposed solid waste landfill at Paducah Gaseous Diffusion Plant  

SciTech Connect

A proposed solid waste landfill at Paducah Gaseous Diffusion Plant (PGDP) would accept wastes generated during normal operations that are identified as non-radioactive. These wastes may include small amounts of radioactive material from incidental contamination during plant operations. A site-specific analysis of the new solid waste landfill is presented to determine a proposed operating limit that will allow for waste disposal operations to occur such that protection of public health and the environment from the presence of incidentally contaminated waste materials can be assured. Performance objectives for disposal were defined from existing regulatory guidance to establish reasonable dose limits for protection of public health and the environment. Waste concentration limits were determined consistent with these performance objectives for the protection of off-site individuals and inadvertent intruders who might be directly exposed to disposed wastes. Exposures of off-site individuals were estimated using a conservative, site-specific model of the groundwater transport of contamination from the wastes. Direct intrusion was analyzed using an agricultural homesteader scenario. The most limiting concentrations from direct intrusion or groundwater transport were used to establish the concentration limits for radionuclides likely to be present in PGDP wastes.

A DUSTY COMPONENT TO THE GASEOUS DEBRIS DISK AROUND THE WHITE DWARF SDSS J1228+1040  

SciTech Connect

We present Infrared Spectrometer And Array Camera (ISAAC) spectroscopy and ISAAC, UKIDSS, and Spitzer Space Telescope broadband photometry of SDSS J1228+1040-a white dwarf for which evidence of a gaseous metal-rich circumstellar disk has previously been found from optical emission lines. The data show a clear excess in the near- and mid-infrared (IR), providing compelling evidence for the presence of dust in addition to the previously identified gaseous debris disk around the star. The IR excess can be modeled in terms of an optically thick but geometrically thin disk. We find that the inner disk temperatures must be relatively high ({approx}1700 K) in order to fit the spectral energy distribution in the near-IR. These data provide the first evidence for the coexistence of both gas and dust in a disk around a white dwarf, and show that their presence is possible even around moderately hot ({approx}22,000 K) stars.

Influence of continuous and discontinuous supplemental lighting on the daily variation in gaseous exchange in greenhouse cucumber  

Science Journals Connector (OSTI)

Stomatal conductance, transpiration, net photosynthesis and internal CO2 concentration were measured on the fifth leaf of 36- to 43-day-old cucumber (Cucumis sativus L.) plants. Three series of measurements followed the variations during a diurnal period in gaseous exchange of plants under three light regimes. One group of plants received supplemental lighting split into two periods (04:00–08:00 and 16:00–22:00) for a continuous 18-h photoperiod. A second group was illuminated between 19:00 and 05:00 for a discontinuous 18-h photoperiod. The last group received only natural light (control). Supplemental lighting increased the stomatal conductance and transpiration. Extending the photoperiod with supplemental lighting increased the net photosynthesis rate and extended the period of CO2 assimilation. The internal CO2 concentration varied inversely with the CO2 assimilation rate. The continuity or discontinuity of the photoperiod did not affect gaseous exchange.

PAndAS IN THE MIST: THE STELLAR AND GASEOUS MASS WITHIN THE HALOS OF M31 AND M33  

SciTech Connect

Large-scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substructure that is thought to be the debris from ancient and ongoing accretion events. In this paper, we compare two extant surveys of the M31-M33 subgroup of galaxies: the Pan-Andromeda Archaeological Survey of the stellar structure, and a combination of observations of the H I gaseous content, detected at 21 cm. Our key finding is a marked lack of spatial correlation between these two components on all scales, with only a few potential overlaps between stars and gas. The paucity of spatial correlation significantly restricts the analysis of kinematic correlations, although there does appear to be H I kinematically associated with the Giant Stellar Stream where it passes the disk of M31. These results demonstrate that different processes must significantly influence the dynamical evolution of the stellar and H I components of substructures, such as ram pressure driving gas away from a purely gravitational path. Detailed modeling of the offset between the stellar and gaseous substructures will provide a determination of the properties of the gaseous halos of M31 and M33.

Summary and Outlook of the International Workshop on Aging Phenomena in Gaseous Detectors (DESY, Hamburg, October, 2001)  

E-Print Network (OSTI)

High Energy Physics experiments are currently entering a new era which requires the operation of gaseous particle detectors at unprecedented high rates and integrated particle fluxes. Full functionality of such detectors over the lifetime of an experiment in a harsh radiation environment is of prime concern to the involved experimenters. New classes of gaseous detectors such as large-scale straw-type detectors, Micro-pattern Gas Detectors and related detector types with their own specific aging effects have evolved since the first workshop on wire chamber aging was held at LBL, Berkeley in 1986. In light of these developments and as detector aging is a notoriously complex field, the goal of the workshop was to provide a forum for interested experimentalists to review the progress in understanding of aging effects and to exchange recent experiences. A brief summary of the main results and experiences reported at the 2001 workshop is presented, with the goal of providing a systematic review of aging effects in state-of-the-art and future gaseous detectors.

Uranium hexafluoride packaging tiedown systems overview at Portsmouth Gaseous Diffusion Plant, Piketon, Ohio. Revision 1  

SciTech Connect

The Portsmouth Gaseous Diffusion Plant (PORTS) in Piketon, Ohio, is operated by Martin Marietta Energy Systems, Inc., through the US Department of Energy-Oak Ridge Operations Office (DOE-ORO) for the US Department of Energy-Headquarters, Office of Nuclear Energy. The PORTS conducts those operations that are necessary for the production, packaging, and shipment of uranium hexafluoride (UF{sub 6}). Uranium hexafluoride enriched uranium than 1.0 wt percent {sup 235}U shall be packaged in accordance with the US Department of Transportation (DOT) regulations of Title 49 CFR Parts 173 (Reference 1) and 178 (Reference 2), or in US Nuclear Regulatory Commission (NRC) or US Department of Energy (DOE) certified package designs. Concerns have been expressed regarding the various tiedown methods and condition of the trailers being used by some shippers/carriers for international transport of the UF{sub 6} cylinders/overpacks. Because of the concerns about international shipments, the US Department of Energy-Headquarters (DOE-HQ) Office of Nuclear Energy, through DOE-HQ Transportation Management Division, requested Westinghouse Hanford Company (Westinghouse Hanford) to review UF{sub 6} packaging tiedown and shipping practices used by PORTS, and where possible and appropriate, provide recommendations for enhancing these practices. Consequently, a team of two individuals from Westinghouse Hanford visited PORTS on March 5 and 6, 1990, for the purpose of conducting this review. The paper provides a brief discussion of the review activities and a summary of the resulting findings and recommendations. A detailed reporting of the is documented in Reference 4.

Ultra-High Energy Cosmic Rays from Centaurus A: Jet Interaction with Gaseous Shells  

E-Print Network (OSTI)

Ultra high energy cosmic rays (UHECRs), with energies above ~6 x 10^19 eV, seem to show a weak correlation with the distribution of matter relatively near to us in the universe. It has earlier been proposed that UHECRs could be accelerated in either the nucleus or the outer lobes of the nearby radio galaxy Cen A. We show that UHECR production at a spatially intermediate location about 15 kpc northeast from the nucleus, where the jet emerging from the nucleus is observed to strike a large star-forming shell of gas, is a plausible alternative. A relativistic jet is capable of accelerating lower-energy heavy seed cosmic rays (CRs) to UHECRs on timescales comparable to the time it takes the jet to pierce the large gaseous cloud. In this model many CRs arising from a starburst, with a composition enhanced in heavy elements near the knee region around PeV, are boosted to ultra-high energies by the relativistic shock of a newly oriented jet. This model matches the overall spectrum shown by the Auger data and also makes a prediction for the chemical composition as a function of particle energy. We thus predict an observable anisotropy in the composition at high energy in the sense that lighter nuclei should preferentially be seen toward the general direction of Cen A. Taking into consideration the magnetic field models for the Galactic disk and a Galactic magnetic wind, this scenario may resolve the discrepancy between HiRes and Auger results concerning the chemical composition of UHECRs.

Modifying woody plants for efficient conversion to liquid and gaseous fuels  

SciTech Connect

The Short Rotation Woody Crop Program (SRWCP), Department of Energy, is developing woody plant species as sources of renewable energy. Much progress has been made in identifying useful species, and testing site adaptability, stand densities, coppicing abilities, rotation lengths, and harvesting systems. Conventional plant breeding and intensive cultural practices have been used to increase above-ground biomass yields. Given these and foreseeable accomplishments, program leaders are now shifting attention to prospects for altering biomass physical and chemical characteristics, and to ways for improving the efficiency with which biomass can be converted to gaseous and liquid fuels. This report provides a review and synthesis of literature concerning the quantity and quality of such characteristics and constituents, and opportunities for manipulating them via conventional selection and breeding and/or molecular biology. Species now used by SRWCP are emphasized, with supporting information drawn from others as needed. Little information was found on silver maple (Acer saccharinum), but general comparisons (Isenberg 1981) suggest composition and behavior similar to those of the other species. Where possible, conclusions concerning means for and feasibility of manipulation are given, along with expected impacts on conversion efficiency. Information is also provided on relationships to other traits, genotype X environment interactions, and potential trade-offs or limitations. Biomass productivity per se is not addressed, except in terms of effects that may by caused by changes in constituent quality and/or quantity. Such effects are noted to the extent they are known or can be estimated. Likely impacts of changes, however effected, on suitability or other uses, e.g., pulp and paper manufacture, are notes. 311 refs., 4 figs., 9 tabs.

Gaseous fission product management for molten salt reactors and vented fuel systems  

SciTech Connect

Fission gas disposal is one of the unresolved difficulties for Molten Salt Reactors (MSRs) and advanced reactors with vented fuel systems. As these systems operate, they produce many radioactive isotopes of xenon and krypton (e.g. {sup 135}Xe t{sub 1/2} = 9.14 hours and {sup 85}Kr t{sub 1/2}= 10.73 years). Removing these gases proves vital to the success of such reactor designs for two reasons. First, the gases act as large neutron sinks which decrease reactivity and must be counterbalanced by increasing fuel loading. Second, for MSRs, inert fission product gases naturally separate quickly from high temperature salts, thus creating high vapor pressure which poses safety concerns. For advanced reactors with solid vented fuel, the gases are allowed to escape into an off-gas system and thus must be managed. Because of time delays in transport of fission product gases in vented fuel systems, some of the shorter-lived radionuclides will decay away thereby reducing the fission gas source term relative to an MSR. To calculate the fission gas source term of a typical molten salt reactor, we modeled a 1000 MWe graphite moderated thorium MSR similar to that detailed in Mathieu et al. [1]. The fuel salt used in these calculations was LiF (78 mole percent) - (HN)F 4 (22 mole percent) with a heavy nuclide composition of 3.86% {sup 233}U and 96.14% {sup 232}Th by mass. Before we can remove the fission product gases produced by this reactor configuration, we must first develop an appropriate storage mechanism. The gases could be stored in pressurized containers but then one must be concerned about bottle failure. Methods to trap noble gases in matrices are expensive and complex. Alternatively, there are direct storage/disposal options: direct injection into the Earth or injecting a grout-based product into the Earth. Advances in drilling technologies, hydro fracture technologies, and methods for the sequestration of carbon dioxide from fossil fuel plants are creating new options for disposal of fission gas wastes. In each option, lithostatic pressure, a kilometer or more underground, eliminates the pressure driving force for noble gas release and dissolves any untrapped gas in deep groundwater or into incorporated solid waste forms. The options, challenges, and potential for these methods to dispose of gaseous fission products are described. With this research, we hope to help both MSRs and other advanced reactors come one step closer to commercialization. (authors)

Safeguards Verification Measurements using Laser Ablation, Absorbance Ratio Spectrometry in Gaseous Centrifuge Enrichment Plants  

SciTech Connect

Laser Ablation Absorbance Ratio Spectrometry (LAARS) is a new verification measurement technology under development at the US Department of Energy’s (DOE) Pacific Northwest National Laboratory (PNNL). LAARS uses three lasers to ablate and then measure the relative isotopic abundance of uranium compounds. An ablation laser is tightly focused on uranium-bearing solids producing a small plume containing uranium atoms. Two collinear wavelength-tuned spectrometry lasers transit through the plume and the absorbance of U-235 and U-238 isotopes are measured to determine U-235 enrichment. The measurement has high relative precision and detection limits approaching the femtogram range for uranium. It is independent of chemical form and degree of dilution with nuisance dust and other materials. High speed sample scanning and pinpoint characterization allow measurements on millions of particles/hour to detect and analyze the enrichment of trace uranium in samples. The spectrometer is assembled using commercially available components at comparatively low cost, and features a compact and low power design. Future designs can be engineered for reliable, autonomous deployment within an industrial plant environment. Two specific applications of the spectrometer are under development: 1) automated unattended aerosol sampling and analysis and 2) on-site small sample destructive assay measurement. The two applications propose game-changing technological advances in gaseous centrifuge enrichment plant (GCEP) safeguards verification. The aerosol measurement instrument, LAARS-environmental sampling (ES), collects aerosol particles from the plant environment in a purpose-built rotating drum impactor and then uses LAARS-ES to quickly scan the surface of the impactor to measure the enrichments of the captured particles. The current approach to plant misuse detection involves swipe sampling and offsite analysis. Though this approach is very robust it generally requires several months to obtain results from a given sample collection. The destructive assay instrument, LAARS-destructive assay (DA), uses a simple purpose-built fixture with a sampling planchet to collect adsorbed UF6 gas from a cylinder valve or from a process line tap or pigtail. A portable LAARS-DA instrument scans the microgram quantity of uranium collected on the planchet and the assay of the uranium is measured to ~0.15% relative precision. Currently, destructive assay samples for bias defect measurements are collected in small sample cylinders for offsite mass spectrometry measurement.

Binary black hole mergers in gaseous environments: 'Binary Bondi' and 'binary Bondi-Hoyle-Lyttleton' accretion  

SciTech Connect

Merging supermassive black hole-black hole binaries produced in galaxy mergers are promising sources of detectable gravitational waves. If such a merger takes place in a gaseous environment, there is a possibility of a simultaneous detection of electromagnetic and gravitational radiation, as the stirring, shock heating, and accretion of the gas may produce variability and enhancements in the electromagnetic flux. Such a simultaneous detection can provide a wealth of opportunities to study gravitational physics, accretion physics, and cosmology. We investigate this scenario by performing fully general-relativistic, hydrodynamic simulations of merging, equal-mass, nonspinning black hole-black hole binaries embedded in gas clouds. We evolve the metric using the Baumgarte-Shapiro-Shibata-Nakamura formulation with standard moving puncture gauge conditions and handle the hydrodynamics via a high-resolution shock-capturing scheme. We consider both 'binary Bondi accretion' in which the binary is at rest relative to the ambient gas cloud, as well as 'binary Bondi-Hoyle-Lyttleton accretion' in which the binary moves relative to the gas cloud. The gas cloud is assumed to be homogeneous far from the binary and governed by a {Gamma}-law equation of state. We vary {Gamma} between 4/3 and 5/3. For each simulation, we compute the gas flow and accretion rate and estimate the electromagnetic luminosity due to bremsstrahlung and synchrotron emission. We find evidence for significant enhancements in both the accretion rate and luminosity over values for a single black hole of the same mass as the binary. We estimate that this luminosity enhancement should be detectable by the Large Synoptic Survey Telescope for a 10{sup 6}M{sub {center_dot}}binary in a hot gas cloud of density n{approx}10 cm{sup -3} and temperature T{approx}10{sup 6} K at z=1, reaching a maximum of L{approx}3x10{sup 43} erg s{sup -1}, with the emission peaking in the visible band, and lasting for {approx}1 hour.

Design of an Unattended Environmental Aerosol Sampling and Analysis System for Gaseous Centrifuge Enrichment Plants  

SciTech Connect

The resources of the IAEA continue to be challenged by the rapid, worldwide expansion of nuclear energy production. Gaseous centrifuge enrichment plants (GCEPs) represent an especially formidable dilemma to the application of safeguard measures, as the size and enrichment capacity of GCEPs continue to escalate. During the early part of the 1990's, the IAEA began to lay the foundation to strengthen and make cost-effective its future safeguard regime. Measures under Part II of 'Programme 93+2' specifically sanctioned access to nuclear fuel production facilities and environmental sampling by IAEA inspectors. Today, the Additional Protocol grants inspection and environmental sample collection authority to IAEA inspectors at GCEPs during announced and low frequency unannounced (LFUA) inspections. During inspections, IAEA inspectors collect environmental swipe samples that are then shipped offsite to an analytical laboratory for enrichment assay. This approach has proven to be an effective deterrence to GCEP misuse, but this method has never achieved the timeliness of detection goals set forth by IAEA. Furthermore it is questionable whether the IAEA will have the resources to even maintain pace with the expansive production capacity of the modern GCEP, let alone improve the timeliness in reaching current safeguards conclusions. New safeguards propositions, outside of familiar mainstream safeguard measures, may therefore be required that counteract the changing landscape of nuclear energy fuel production. A new concept is proposed that offers rapid, cost effective GCEP misuse detection, without increasing LFUA inspection access or introducing intrusive access demands on GCEP operations. Our approach is based on continuous onsite aerosol collection and laser enrichment analysis. This approach mitigates many of the constraints imposed by the LFUA protocol, reduces the demand for onsite sample collection and offsite analysis, and overcomes current limitations associated with the in-facility misuse detection devices. Onsite environmental sample collection offers the ability to collect fleeting uranium hexafluoride emissions before they are lost to the ventilation system or before they disperse throughout the facility, to become deposited onto surfaces that are contaminated with background and historical production material. Onsite aerosol sample collection, combined with enrichment analysis, provides the unique ability to quickly detect stepwise enrichment level changes within the facility, leading to a significant strengthening of facility misuse deterence. We report in this paper our study of several GCEP environmental sample release scenarios and simulation results of a newly designed aerosol collection and particle capture system that is fully integrated with the Laser Ablation, Absorbance Ratio Spectrometry (LAARS) uranium particle enrichment analysis instrument that was developed at the Pacific Northwest National Laboratory.

Equations of motion in metric-affine gravity: A covariant unified framework  

Science Journals Connector (OSTI)

We derive the equations of motion of extended deformable bodies in metric-affine gravity. The conservation laws which follow from the invariance of the action under the general coordinate transformations are used as a starting point for the discussion of the dynamics of extended deformable test bodies. By means of a covariant approach, based on Synge’s world function, we obtain the master equation of motion for an arbitrary system of coupled conserved currents. This unified framework is then applied to metric-affine gravity. We confirm and extend earlier findings; in particular, we once again demonstrate that it is only possible to detect the post-Riemannian spacetime geometry by ordinary (nonmicrostructured) test bodies if gravity is nonminimally coupled to matter.

Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension  

E-Print Network (OSTI)

The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides a geometric description of the density matrix in terms of the polarization vector representation. This has been thoroughly explored for qubits since the components of the polarization vector are measurable quantities (corresponding to expectation values of Hermitian operators) and also because it enables the description of map domains geometrically. Here we extend the OS-affine map correspondence to qudits, briefly discuss general properties of the map, the form for particular important cases, and provide several explicit results for qutrit maps. We use the affine map and a singular-value-like decomposition, to find positivity constraints that provide a symmetry for small polarization vector magnitudes (states which are closer to the maximally mixed state) which is broken as the polarization vector increases in magnitude (a state becomes more pure). The dependence of this symmetry on the magnitude of the polarization vector implies the polar decomposition of the map can not be used as it can for the qubit case. However, it still leads us to a connection between positivity and purity for general d-state systems.

The Radiochemical Analysis of Gaseous Samples (RAGS) apparatus for nuclear diagnostics at the National Ignition Facility (invited)  

SciTech Connect

The Radiochemical Analysis of Gaseous Samples (RAGS) diagnostic apparatus was recently installed at the National Ignition Facility (NIF). Following a NIF shot, RAGS is used to pump the gas load from the NIF chamber for purification and isolation of the noble gases. After collection, the activated gaseous species are counted via gamma spectroscopy for measurement of the capsule areal density and fuel-ablator mix. Collection efficiency was determined by injecting a known amount of {sup 135}Xe into the NIF chamber, which was then collected with RAGS. Commissioning was performed with an exploding pusher capsule filled with isotopically enriched {sup 124}Xe and {sup 126}Xe added to the DT gas fill. Activated xenon species were recovered post-shot and counted via gamma spectroscopy. Results from the collection and commissioning tests are presented. The performance of RAGS allows us to establish a noble gas collection method for measurement of noble gas species produced via neutron and charged particle reactions in a NIF capsule.

Performance of a low-cost iron ore as an oxygen carrier for Chemical Looping Combustion of gaseous fuels  

Science Journals Connector (OSTI)

Abstract This work evaluates the performance of an iron ore, mainly composed of Fe2O3, as an oxygen carrier (OC) for Chemical Looping Combustion (CLC) with gaseous fuels. The OC was characterized by TGA and evaluated in a continuous 500 Wth CLC unit, using CH4, syngas and a PSA off-gas as fuels. The OC was able to fully convert syngas at 880 °C. However, lower conversion rates were observed with methane-containing fuels. The addition of a Ni-based OC was evaluated in order to increase the reactivity of the OC with methane. In spite of this, an absence of catalytic effect was observed for the Ni-based OC. A deep analysis was carried out into the reasons for the absence of catalytic effect of the Ni-based OC. The performance of the iron ore with regard to attrition and fluidization behaviour was satisfactory throughout 50 h of hot operation in the continuous CLC plant. Thus, this low cost material is a suitable OC for gaseous fuels mainly composed of H2 and CO.

Detection of the primary scintillation light from dense Ar, Kr and Xe with novel photosensitive gaseous detectors  

E-Print Network (OSTI)

The detection of primary scintillation light in combination with the charge or secondary scintillation signals is an efficient technique to determine the events t=0 as well as particle / photon separation in large mass TPC detectors filled with noble gases and/or condensed noble gases. The aim of this work is to demonstrate that costly photo-multipliers could be replaced by cheap novel photosensitive gaseous detectors: wire counters, GEMs or glass capillary tubes coupled with CsI photocathodes. We have performed systematic measurements with Ar, Kr and Xe gas at pressures in the range of 1-50 atm as well as some preliminary measurements with liquid Xe and liquid Ar. With the gaseous detectors we succeeded in detecting scintillation light produced by 22 keV X-rays with an efficiency of close to 100%. We also detected the scintillation light produced by bs (5 keV deposit energy) with an efficiency close to 25%. Successful detection of scintillation from 22 keV gammas open new experimental possibilities not only ...

Hydraulic Containment of TCE Contaminated Groundwater at the DOE Portsmouth Gaseous Diffusion Plant  

SciTech Connect

This paper will describe the progress of a groundwater remedial action at the Portsmouth Gaseous Diffusion Plant (PORTS), a Department of Energy (DOE) facility that enriched uranium from the early 1950's until 2000. The X-749 southern boundary hydraulic containment system, combining a four-well extraction system with a previously constructed subsurface barrier wall, has been employed at PORTS. The hydraulic containment project has been implemented as part of containment and remediation of the X-749/X-120 area trichloroethylene (TCE) contaminant. The X-749/X-120 groundwater contaminant plume is located in the south central section (Quadrant I) of the PORTS facility. The plume is associated with the former X-120 Goodyear Training Facility and a landfill known as the X-749 Contaminated Materials Disposal Facility. The principal contaminants of concern are chlorinated solvents (primarily TCE) and technetium-99 (Tc-99). A subsurface barrier wall (X-749 South Barrier Wall) was completed in 1994 at the PORTS southern reservation boundary as an interim remedial measure to slow the advancement of the leading edge of the contaminated groundwater plume or to prevent the plume from migrating off DOE property. Remedial measures identified by Ohio Environmental Protection Agency (Ohio EPA) included installation of a barrier wall around the eastern and southern portions of the X-749 landfill to provide source control and installation of a phyto-remediation system to help contain groundwater flow and remove volatile organic compounds. Previous remedial measures that were implemented as elements of 'closures' on the X-749 landfill included a multimedia cap, barrier walls, and a groundwater collection system. Despite these measures, the X-749/X-120 groundwater plume has migrated beyond the southern DOE property boundary. Current TCE concentrations in off-site groundwater monitoring wells are below the preliminary remediation goal and drinking water maximum contaminant level for TCE of 5 {mu}g/kg, but continue to increase. Hydraulic containment was selected as the method for controlling the plume at the southern DOE property boundary. Recent borings and pumping tests indicate that approximately a 400-foot section of the existing subsurface barrier wall near the DOE property boundary may been improperly keyed into the Sunbury Shale bedrock which underlies the unconsolidated uppermost Gallia sand and gravel aquifer (Gallia). This gap is reported to be as much as 4 vertical feet. In addition, the X-749 groundwater plume is migrating around the western end of the X-749 South Barrier Wall. Four groundwater extraction wells were installed at the DOE property boundary to provide hydraulic control of the plume currently flowing under and around the existing subsurface barrier wall. Placement of the new extraction wells was based on groundwater modeling and data collected from pumping tests in the area. The extracted groundwater is being sent to the on-site X-622 Groundwater Treatment Facility via subsurface piping. The hydraulic containment system began operation in June 2007. The preliminary water elevations from monitoring wells in the vicinity of two of the four extraction wells demonstrate a significant decrease in groundwater potentiometric head in the southern boundary area. The current extraction rates should be adequate to contain the leading edge of the contaminant plume. Monitoring wells in the area will continue to be sampled on a quarterly basis. (authors)

Evidences for secondary cracking of oil in South Pars field, Persian Gulf, Iran  

Science Journals Connector (OSTI)

Condensates and natural gases in South Pars, world's largest gas field in Persian Gulf were studied for their geochemical characteristics and possibility of secondary cracking as a major gas producing mechanism. Carbon isotopic analysis of gas components proposes thermogenic origin for South Pars gas field. However, ?13C values of Methane and Ethane are slightly depleted in comparison with generated gas from primary thermogenic gas whereas gases from secondary cracking of oils are systematically depleted in 13C in Methane and Ethane compared to gases from primary cracking. Gas composition of Head-Space gas samples were plotted in Ln(C1/C2) vs. Ln(C2/C3) diagram that all the data points indicate a noticeable shift toward trend of secondary cracking, indicating frequency of higher components i.e. C2+. Silurian black shales are recognized as most important source rock for the South Pars field. Biomarker analysis of hydrocarbon liquid samples indicates Pristane to Phytane ratio is > 1 that could confirm mentioned shaly source rock which is deposited in suboxic to oxic marine environment. Considering of ?13C of Silurian shales the “?13C Methane-?13C Source” was calculated and plotted against C1/?C1–5 indicating effect of secondary cracking of oil as producing mechanism for South Pars gas field. Moreover, pyro-bitumen as product of the secondary cracking was found filling secondary porosities in bottom part of the reservoir.

Project Plan 7930 Cell G PaR Remote Handling System Replacement  

SciTech Connect

For over 40 years the US Department of Energy (DOE) and its predecessors have made Californium-252 ({sup 252}Cf) available for a wide range of industries including medical, nuclear fuels, mining, military and national security. The Radiochemical Engineering Development Center (REDC) located within the Oak Ridge National Laboratory (ORNL) processes irradiated production targets from the High Flux Isotope Reactor (HFIR). Operations in Building 7930, Cell G provide over 70% of the world's demand for {sup 252}Cf. Building 7930 was constructed and equipped in the mid-1960s. Current operations for {sup 252}Cf processing in Building 7930, Cell G require use of through-the-wall manipulators and the PaR Remote Handling System. Maintenance and repairs for the manipulators is readily accomplished by removal of the manipulator and relocation to a repair shop where hands-on work can be performed in glove boxes. Contamination inside cell G does not currently allow manned entry and no provisions were created for a maintenance area inside the cell. There has been no maintenance of the PaR system or upgrades, leaving operations vulnerable should the system have a catastrophic failure. The Cell G PaR system is currently being operated in a run to failure mode. As the manipulator is now 40+ years old there is significant risk in this method of operation. In 2006 an assessment was completed that resulted in recommendations for replacing the manipulator operator control and power centers which are used to control and power the PaR manipulator in Cell G. In mid-2008 the chain for the bridge drive failed and subsequent examinations indicated several damaged links (see Figure 1). To continue operations the PaR manipulator arm is being used to push and pull the bridge as a workaround. A retrieval tool was fabricated, tested and staged inside Cell G that will allow positioning of the bridge and manipulator arm for removal from the cell should the PaR system completely fail. A fully functioning and reliable Par manipulator arm is necessary for uninterrupted {sup 252}Cf operations; a fully-functioning bridge is needed for the system to function as intended.

Influence of Linker Structure on the Anion Binding Affinity of Biscyclopeptides  

SciTech Connect

A systematic analysis is presented on the influence of the linking unit between two cyclopeptide rings on the affinity of such biscyclopeptide-based anion receptors in aqueous solvent mixtures. Although the differences in the affinity and selectivity of these receptors toward a given anion are not very pronounced, there are profound differences in the thermodynamics of anion complexation. Enthalpic and entropic contributions both (1) play a role in determining the binding affinity and (2) show significant variation as the linking structure is changed. A decrease in conformational rigidity of the linker improves the entropic advantage for complex formation, but not necessarily the overall complex stability. This effect may be due, in part, to the fact that structural constraints within more rigid linkers might prevent efficient interactions between the host and guest. The optimal linker, which exhibits both favourable enthalpic and entropic contributions, was identified using de novo structure-based design methods as implemented in the HostDesigner software.

Efficient Selection of \\{DARPins\\} with Sub-nanomolar Affinities using SRP Phage Display  

Science Journals Connector (OSTI)

There is an ever-increasing demand to select specific, high-affinity binding molecules against targets of biomedical interest. The success of such selections depends strongly on the design and functional diversity of the library of binding molecules employed, and on the performance of the selection strategy. We recently developed SRP phage display that employs the cotranslational signal recognition particle (SRP) pathway for the translocation of proteins to the periplasm. This system allows efficient filamentous phage display of highly stable and fast-folding proteins, such as designed ankyrin repeat proteins (DARPins) that are virtually refractory to conventional phage display employing the post-translational Sec pathway. \\{DARPins\\} comprise a novel class of binding molecules suitable to complement or even replace antibodies in many biotechnological or biomedical applications. So far, all \\{DARPins\\} have been selected by ribosome display. Here, we harnessed SRP phage display to generate a phage \\{DARPin\\} library containing more than 1010 individual members. We were able to select well behaved and highly specific \\{DARPins\\} against a broad range of target proteins having affinities as low as 100 pM directly from this library, without affinity maturation. We describe efficient selection on the Fc domain of human IgG, TNF?, ErbB1 (EGFR), ErbB2 (HER2) and ErbB4 (HER4) as examples. Thus, SRP phage display makes filamentous phage display accessible for DARPins, allowing, for example, selection under harsh conditions or on whole cells. We envision that the use of SRP phage display will be beneficial for other libraries of stable and fast-folding proteins.

The CP(N-1) Affine Gauge Theory in the Dynamical Space-time  

E-Print Network (OSTI)

An attempt to build quantum theory of field (extended) objects without a priori space-time geometry has been represented. Space-time coordinates are replaced by the intrinsic coordinates in the tangent fibre bundle over complex projective Hilbert state space $CP(N-1)$. The fate of a quantum system modeled by the generalized coherent states is rooted in this manifold. Dynamical (state-dependent) space-time arises only at the stage of the quantum "yes/no" measurement. The quantum measurement of the gauge ``field shell'' of the generalized coherent state is described in terms of the affine parallel transport of the local dynamical variables in $CP(N-1)$.

Gamma radiological surveys of the Oak Ridge Reservation, Paducah Gaseous Diffusion Plant, and Portsmouth Gaseous Diffusion Plant, 1990-1993, and overview of data processing and analysis by the Environmental Restoration Remote Sensing Program, Fiscal Year 1995  

SciTech Connect

Three gamma radiological surveys have been conducted under auspices of the ER Remote Sensing Program: (1) Oak Ridge Reservation (ORR) (1992), (2) Clinch River (1992), and (3) Portsmouth Gaseous Diffusion Plant (PORTS) (1993). In addition, the Remote Sensing Program has acquired the results of earlier surveys at Paducah Gaseous Diffusion Plant (PGDP) (1990) and PORTS (1990). These radiological surveys provide data for characterization and long-term monitoring of U.S. Department of Energy (DOE) contamination areas since many of the radioactive materials processed or handled on the ORR, PGDP, and PORTS are direct gamma radiation emitters or have gamma emitting daughter radionuclides. High resolution airborne gamma radiation surveys require a helicopter outfitted with one or two detector pods, a computer-based data acquisition system, and an accurate navigational positioning system for relating collected data to ground location. Sensors measure the ground-level gamma energy spectrum in the 38 to 3,026 KeV range. Analysis can provide gamma emission strength in counts per second for either gross or total man-made gamma emissions. Gross count gamma radiation includes natural background radiation from terrestrial sources (radionuclides present in small amounts in the earth`s soil and bedrock), from radon gas, and from cosmic rays from outer space as well as radiation from man-made radionuclides. Man-made count gamma data include only the portion of the gross count that can be directly attributed to gamma rays from man-made radionuclides. Interpretation of the gamma energy spectra can make possible the determination of which specific radioisotopes contribute to the observed man-made gamma radiation, either as direct or as indirect (i.e., daughter) gamma energy from specific radionuclides (e.g., cesium-137, cobalt-60, uranium-238).

Gaseous Mean Opacities for Giant Planet and Ultracool Dwarf Atmospheres over a Range of Metallicities and Temperatures  

E-Print Network (OSTI)

We present new calculations of Rosseland and Planck gaseous mean opacities relevant to the atmospheres of giant planets and ultracool dwarfs. Such calculations are used in modeling the atmospheres, interiors, formation, and evolution of these objects. Our calculations are an expansion of those presented in Freedman et al. (2008) to include lower pressures, finer temperature resolution, and also the higher metallicities most relevant for giant planet atmospheres. Calculations span 1 microbar to 300 bar, and 75 K to 4000 K, in a nearly square grid. Opacities at metallicities from solar to 50 times solar abundances are calculated. We also provide an analytic fit to the Rosseland mean opacities over the grid in pressure, temperature, and metallicity. In addition to computing mean opacities at these local temperatures, we also calculate them with weighting functions up to 7000 K, to simulate the mean opacities for incident stellar intensities, rather than locally thermally emitted intensities.

Detection of illicit HEU production in gaseous centrifuge enrichment plants using neutron counting techniques on product cylinders  

SciTech Connect

Innovative and novel safeguards approaches are needed for nuclear energy to meet global energy needs without the threat of nuclear weapons proliferation. Part of these efforts will include creating verification techniques that can monitor uranium enrichment facilities for illicit production of highly-enriched uranium (HEU). Passive nondestructive assay (NDA) techniques will be critical in preventing illicit HEU production because NDA offers the possibility of continuous and unattended monitoring capabilities with limited impact on facility operations. Gaseous centrifuge enrichment plants (GCEP) are commonly used to produce low-enriched uranium (LEU) for reactor fuel. In a GCEP, gaseous UF{sub 6} spins at high velocities in centrifuges to separate the molecules containing {sup 238}U from those containing the lighter {sup 235}U. Unfortunately, the process for creating LEU is inherently the same as HEU, creating a proliferation concern. Insuring that GCEPs are producing declared enrichments poses many difficult challenges. In a GCEP, large cascade halls operating thousands of centrifuges work together to enrich the uranium which makes effective monitoring of the cascade hall economically prohibitive and invasive to plant operations. However, the enriched uranium exiting the cascade hall fills product cylinders where the UF{sub 6} gas sublimes and condenses for easier storage and transportation. These product cylinders hold large quantities of enriched uranium, offering a strong signal for NDA measurement. Neutrons have a large penetrability through materials making their use advantageous compared to gamma techniques where the signal is easily attenuated. One proposed technique for detecting HEU production in a GCEP is using neutron coincidence counting at the product cylinder take off stations. This paper discusses findings from Monte Carlo N-Particle eXtended (MCNPX) code simulations that examine the feasibility of such a detector.

Preparation and evaluation of spore-specific affinity- augmented bio-imprinted beads  

SciTech Connect

The procedures previously described for imprinting bead surfaces with bacteria were applied to create novel affinity-augmented bacterial spore-imprinted beads. The imprinted beads are intended as a front-end spore capture/concentration stage of an integrated biological detection system. Our approach involves embedding bead surfaces with Bacillus thuringiensis kurstaki (Bt) spores (as a surrogate for Bacillus anthracis) during synthesis. Subsequent steps involved lithographic deactivation using a perfluoroether, spore removal to create imprint sites, and coating imprints with the lectin, concanavalin A, to provide general affinity. The synthesis of the intended material with the desired imprints was verified by scanning electron and confocal laser-scanning microscopy. The material was evaluated using spore-binding assays with either Bt or Bacillus subtilis (Bs) spores. The binding assays indicated strong spore-binding capability and a robust imprinting effect that accounted for 25 percent additional binding over nonimprinted controls. The binding assay results also indicated that further refinement of the surface deactivation procedure would enhance the performance of the imprinted substrate.

Standard emitters (clocks) and calibrated standard emitters (clocks) in spaces with affine connections and metrics  

E-Print Network (OSTI)

It is shown that the general belief that the frequency and the absolute value of the velocity of periodic signals sent by a standard emitter do not change on the world line of the emitter needs to be revised and new conditions for the existence of a calibrted standard emitter should be taken into account. The notions of a standard clock and of a calibrated standard clock are introduced in a space with affine connections and metrics. The variation of the velocity and of the frequency of a standard clock could be compared with the constant velocity and the constant frequency of a calibrated standard clock along the world line of the observer. This calibrated standard clock is transported by meand of a generalized Fermi-Walker transport along the same world line of the observer. Some remarks about the synchronization of standard clocks in spaces with affine connections and metrics are given. PACS numbers: 95.30.Sf; 04.90.+h; 04.20.Cv; 04.90.+e

Structural control of elastic moduli in ferrogels and the importance of non-affine deformations  

E-Print Network (OSTI)

One of the central appealing properties of magnetic gels and elastomers is that their elastic moduli can reversibly be adjusted from outside by applying magnetic fields. The impact of the internal magnetic particle distribution on this effect has been outlined and analyzed theoretically. In most cases, however, affine sample deformations are studied and often regular particle arrangements are considered. Here we challenge these two major simplifications by a systematic approach using a minimal dipole-spring model. Starting from different regular lattices, we take into account increasingly randomized structures, until we finally investigate an irregular texture taken from a real experimental sample. On the one hand, we find that the elastic tunability qualitatively depends on the structural properties, here in two spatial dimensions. On the other hand, we demonstrate that the assumption of affine deformations leads to increasingly erroneous results the more realistic the particle distribution becomes. Understanding the consequences of the assumptions made in the modeling process is important on our way to support an improved design of these fascinating materials.

Modeling of reverse osmosis in the presence of strong solute-membrane affinity  

SciTech Connect

Modeling of reverse osmosis in the presence of strong solute-membrane affinity has always been a challenge due to the complexity of the solute-solvent-membrane interactions and the resultant effect on membrane performance. Most transport models, including all models treating membranes as nonporous and those based on irreversible thermodynamics, are unable to describe or to predict all of the phenomena associated with this case. Recently, the modified surface force-pore flow model has been derived and used to describe the performance of reverse osmosis membranes for solutes which are rejected from the membrane. In the present work, this model is extended to a more general form which can describe the solute-membrane affinity case. For illustration, the extended model, with five adjustable parameters, is used to describe the performance for cellulose acetate membranes and dilute aqueous solutions of toluene, cumene, and p-chlorophenol (data from literature). The model is reasonably consistent with the data. Simulation results of the extended model are also shown.

AN AFFINE-INVARIANT SAMPLER FOR EXOPLANET FITTING AND DISCOVERY IN RADIAL VELOCITY DATA  

SciTech Connect

Markov chain Monte Carlo (MCMC) proves to be powerful for Bayesian inference and in particular for exoplanet radial velocity fitting because MCMC provides more statistical information and makes better use of data than common approaches like chi-square fitting. However, the nonlinear density functions encountered in these problems can make MCMC time-consuming. In this paper, we apply an ensemble sampler respecting affine invariance to orbital parameter extraction from radial velocity data. This new sampler has only one free parameter, and does not require much tuning for good performance, which is important for automatization. The autocorrelation time of this sampler is approximately the same for all parameters and far smaller than Metropolis-Hastings, which means it requires many fewer function calls to produce the same number of independent samples. The affine-invariant sampler speeds up MCMC by hundreds of times compared with Metropolis-Hastings in the same computing situation. This novel sampler would be ideal for projects involving large data sets such as statistical investigations of planet distribution. The biggest obstacle to ensemble samplers is the existence of multiple local optima; we present a clustering technique to deal with local optima by clustering based on the likelihood of the walkers in the ensemble. We demonstrate the effectiveness of the sampler on real radial velocity data.

The assessment of reliability levels of the BRASIL-SR model were performed through the evaluation of the deviations shown by the estimated values for solar radiation flux vis-à-vis the values measured at the surface (ground truth). This evaluation was done in two phases. The first phase consisted in an inter-comparison between the core radiation transfer models adopted by the SWERA Project to map the solar energy n the various countries participating in the project. The HELIOSAT model took part in this phase like benchmark due to its employment to apply solar energy resources in countries from European Union. In the second phase, the solar flux estimates provided by the BRASIL-SR model were compared with measured values acquired at several solarimetric stations spread along the Brazilian territory. The BRASIL-SR model is not validated for areas covered by snow.

K-Area and Par Pond Sewage Sludge Application Sites groundwater monitoring report: Second quarter 1993

During second quarter 1993, samples from the three monitoring wells at the K-Area site (KSS series) and the three monitoring wells at the Par Pond site (PSS series) were analyzed for constituents required by South Carolina Department of Health and Environmental Control Construction Permit 13,173 and for other constituents as part of the Savannah River Site (SRS) Groundwater Monitoring Program. This report describes monitoring results that exceeded the final Primary Drinking Water Standards (PDWS) or the SRS flagging criteria. During second quarter 1993, no constituents exceeded the final PDWS or any other flagging criteria at the K-Area and Par Pond Sewage Sludge Application Sites. During first quarter 1993, aluminum and iron exceeded the SRS Flag 2 criteria in one or more of the KSS and the PSS wells. These constituents were not analyzed second quarter 1993. In the KSS well series, the field measurement for alkalinity ranged as high as 35 mg/L in well KSS 1D. Alkalinity measurements were zero in the PSS wells, except for a single measurement of 1 mg/L in well PSS 1D. Historical and current water-level elevations at the K-Area Sewage Sludge Application Site indicate that the groundwater flow direction is south to southwest (SRS grid coordinates). The groundwater flow direction at the Par Pond Sewage Sludge Application Site could not be determined second quarter 1993.

High-Affinity and Cooperative Binding of Oxidized Calmodulin by Methionine Sulfoxide Reductase  

SciTech Connect

Methionines play an important role in modulating protein-protein interactions associated with intracellular signaling, and their reversible oxidation to form methionine sulfoxides [Met(O)] in calmodulin (CaM) and other signaling proteins has been suggested to couple cellular redox changes to protein function changes through the action of methionine sulfoxide reductases (Msr). Prior measurements indicate the full recovery of target protein activation upon the stereospecific reduction of oxidized CaM by MsrA, where the formation of the S-stereoisomer of Met(O) selectively inhibits the CaM-dependent activation of the Ca-ATPase. However, the physiological substrates of MsrA remain unclear, as neither the binding specificities nor affinities of protein targets have been measured. To assess the specificity of binding and its possible importance in the maintenance of CaM function, we have measured the kinetics of repair and the binding affinity between oxidized CaM and MsrA. Reduction of Met(O) in fully oxidized CaM by MsrA is sensitive to protein folding, as repair of the intact protein is incomplete, with > 6 Met(O) remaining in each CaM following MsrA reduction. In contrast, following proteolytic digestion, MsrA is able to fully reduce one-half of the oxidized methionines, indicating that Met(O) within folded proteins are not substrates for MsrA repair. Further, in comparison to free Met(O), the turnover number and Km for oxidized CaM (CaMox) are substantially smaller, indicating that the binding interaction retards Msr recycling to reduce steady-state enzyme activity. Mutation of the active site (i.e., C72S) in MsrA permitted equilibrium-binding measurements using both ensemble and single-molecule measurements obtained by fluorescence correlation spectroscopy (FCS). Multiple MsrA bind tightly to CaMox (Kd = 70 +- 10 nM) with an affinity that is three orders of magnitude greater than the Michaelis constant (KM = 71 +- 8 micromolar). These results indicate that MsrA selectively reduces surface-exposed Met(O) within unstructured sequences and suggest that only a small subset of oxidized proteins are substrates for MsrA, which may selectively modulate the function of key signaling proteins as part of an adaptive response to oxidative stress.

Organic geochemistry of Gadvan and Kazhdumi formations (Cretaceous) in South Pars field, Persian Gulf, Iran  

Science Journals Connector (OSTI)

In Southern Iran, Gadvan (Barremian-early Aptian) and Kazhdumi (Albian) formations are the most effective source rocks and have produced the majority of hydrocarbons reserved in the Zagros Basin especially in Dezful Embayment and Persian Gulf area. In this article, hydrocarbon potential of Gadvan and Kazhdumi formations is investigated in the South Pars field which is southern extension of the North field of Qatar Country. This field is located in Persian Gulf waters and is actually the northern extension of Qatar Arc Paleohigh where geological history of Gadvan and Kazhdumi formations is different from nearby area regarding depositional setting, burial history and source rock maturity. In this study, Gadvan and Kazhdumi formations as source rock candidates, which underlay Upper Dariyan and Mauddud members, respectively, were sampled in two drilled wells of the South Pars field for routine geochemical analysis to investigate hydrocarbon potential of these formations and source rock identification of trapped oil in the Upper Dariyan and Mauddud members. Several samples from top to the bottom of the formations were taken and analyzed by Rock-Eval pyrolysis. The average TOC content of Gadvan and Kazhdumi formations is 0.79 wt. % and 0.49 wt. %, respectively. Rock-Eval results (e.g. HI vs. Tmax) represent that TOC content of these formations contains type II-III kerogens which haven't suffered sufficient thermal maturity (Ro < 0.5%) in this study area. Moreover calculated S2/S3 ratio implies that these formations in central part of Qatar Arc, South Pars field couldn't produce noticeable liquid hydrocarbon. As it is believed, Gadvan and Kazhdumi formations to be source of trapped oil in the system, therefore, in the South Pars field reserved hydrocarbon in Upper Dariyan (Aptian) and Mauddud (late Albian) members which overlie Gadvan and Kazhdumi formations, respectively, are probably generated from Gadvan and Kazhdumi formations of the nearby through and flanks of the Qatar Arc where the burial depth and temperature increase then generated hydrocarbons in downdip area are migrated to the upper carbonate reservoirs in the crest part of the Qatar Arc. Long path migration of the hydrocarbon and source rock with lower organic matter are caused hydrocarbon accumulation in the South Pars Oil Layer (Al-Shaheen) which is approved by professional petrophysical and geological studies of the field.

Let $(G,{\\mathfrak I},N,S)$ be an affine topological Tits system, and let $\\Gamma$ be a torsion free cocompact lattice in $G$. This article studies the coinvariants $H_0(\\Gamma; C(\\Omega,{\\mathbb Z}))$, where $\\Omega$ is the Furstenberg boundary of $G$. It is shown that the class $[1]$ of the identity function in $H_0(\\Gamma; C(\\Omega,{\\mathbb Z}))$ has finite order, with explicit bounds for the order. A similar statement applies to the $K_0$ group of the boundary crossed product $C^*$-algebra $C(\\Omega)\\rtimes\\Gamma$. If the Tits system has type $\\widetilde A_2$, exact computations are given, both for the crossed product algebra and for the reduced group $C^*$-algebra.

CAF-FrFT: A center-affine-filter with fractional Fourier transform to reduce the cross-terms of Wigner distribution  

Science Journals Connector (OSTI)

As a popular time-frequency representation, the Wigner distribution (WD) enjoys its excellent property of highly concentrated auto-terms, but suffers from cross-term problem. To reduce the cross-terms, we propose a method to apply a center-affine-filter ... Keywords: Center-affine-filter, Cross-terms, Fractional Fourier transform, Principal axes, Wigner distribution

2d Affine XY-Spin Model/4d Gauge Theory Duality and Deconfinement  

SciTech Connect

We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2) and SU(2) = Z{sub 2} gauge theories, compactified on a small spatial circle R{sup 1,2} x S{sup 1}, and considered at temperatures near the deconfinement transition. In a Euclidean set up, the theory is defined on R{sup 2} x T{sup 2}. Similarly, thermal gauge theories of higher rank are dual to new families of 'affine' XY-spin models with perturbations. For rank two, these are related to models used to describe the melting of a 2d crystal with a triangular lattice. The connection is made through a multi-component electric-magnetic Coulomb gas representation for both systems. Perturbations in the spin system map to topological defects in the gauge theory, such as monopole-instantons or magnetic bions, and the vortices in the spin system map to the electrically charged W-bosons in field theory (or vice versa, depending on the duality frame). The duality permits one to use the two-dimensional technology of spin systems to study the thermal deconfinement and discrete chiral transitions in four-dimensional SU(N{sub c}) gauge theories with n{sub f} {ge} 1 adjoint Weyl fermions.

Quantitatively identical orientation-dependent ionization energy and electron affinity of diindenoperylene  

SciTech Connect

Molecular orientation dependences of the ionization energy (IE) and the electron affinity (EA) of diindenoperylene (DIP) films were studied by using ultraviolet photoemission spectroscopy and inverse photoemission spectroscopy. The molecular orientation was controlled by preparing the DIP films on graphite and SiO{sub 2} substrates. The threshold IE and EA of DIP thin films were determined to be 5.81 and 3.53 eV for the film of flat-lying DIP orientation, respectively, and 5.38 and 3.13 eV for the film of standing DIP orientation, respectively. The result indicates that the IE and EA for the flat-lying film are larger by 0.4 eV and the frontier orbital states shift away from the vacuum level compared to the standing film. This rigid energy shift is ascribed to a surface-electrostatic potential produced by the intramolecular polar bond (>C{sup ?}-H{sup +}) for standing orientation and ?-electron tailing to vacuum for flat-lying orientation.

Electron affinity of Pa by 7p attachment and hyperfine structure constants for Pa-  

Science Journals Connector (OSTI)

Valence shell relativistic configuration interaction calculations for the 7p attachment to the Pa I ground state yield one bound state, viz., Pa- 5f26d7s27p J=6, with electron affinity of 0.222 eV. We found no other J’s for this configuration to be bound, nor are any of the Pa- 5f26d27s2 levels expected to be bound. The hyperfine structure constants for the Pa-231 bound state are A=741.3 MHz and B=1309 MHz. Although the core-valence correlation effects are absent the agreement between the theory (4736 cm-1) and experiment (4121 cm-1) for the position of the first excited state of Pa is good (15%). We review our previous studies for the np attachment in rare earths to systematically analyze the binding of np1/2 and np3/2 electrons, in these species. © 1996 The American Physical Society.

Combustion regimes of particle-laden gaseous flames: influences of radiation, molecular transports, kinetic-quenching, stoichiometry  

Science Journals Connector (OSTI)

We study flat flames propagating steadily in a reactive gaseous premixture which is seeded with an inert solid suspension. Our main assumptions are: (i) the two-reactant, one-step overall reaction we choose as the combustion process has a rate which vanishes at and below a prescribed temperature (Tc) and resumes the Arrhenius form at higher temperatures; (ii) both phases are considered as continua and have the same local speed and temperature; (iii) radiation among the particles follows the Eddington approximation specialized to a grey medium and the attenuation length markedly exceeds the conduction - convection length in the gas; (iv) the activation energy is large. The first regimes we consider comprise a thin flame front (dominated by molecular transports, convection and chemistry) embedded in much thicker radiation - convection zones. Jump conditions across the former are derived analytically and then used as targets in a shooting method to analyse the thickest zones and compute the burning speed (U). Such regimes only exist for equivalence ratios () above a load-dependent critical value which corresponds to a turning point of the U() curve. This turning point is due to radiative heat losses from the thin flame front to the cooler adjacent zones, which lead to extinction. Over restricted, well defined ranges of composition other regimes may also exist, which have monotonic temperature profiles culminating slightly above Tc. When they are too thick to be affected by molecular transports and are thus similar to coal-dust -air flames, their structure, domain of existence and speed are investigated analytically and numerically. The corresponding U() curve exhibits an upper limit equivalence ratio * characterized by an end-point, beyond which such regimes cannot exist. The influence of molecular diffusion is then accounted for and shown to modify the results only slightly.

Unattended Monitoring of HEU Production in Gaseous Centrifuge Enrichment Plants using Automated Aerosol Collection and Laser-based Enrichment Assay  

SciTech Connect

Nuclear power is enjoying rapid growth as government energy policies and public demand shift toward low carbon energy production. Pivotal to the global nuclear power renaissance is the development and deployment of robust safeguards instrumentation that allows the limited resources of the IAEA to keep pace with the expansion of the nuclear fuel cycle. Undeclared production of highly enriched uranium (HEU) remains a primary proliferation concern for modern gaseous centrifuge enrichment plants (GCEPs), due to their massive separative work unit (SWU) processing power and comparably short cascade equilibrium timescale. The Pacific Northwest National Laboratory is developing an unattended safeguards instrument, combining continuous aerosol particulate collection with uranium isotope assay, to provide timely detection of HEU production within a GCEP. This approach is based on laser vaporization of aerosol particulates, followed by laser spectroscopy to characterize the uranium enrichment level. Our prior investigation demonstrated single-shot detection sensitivity approaching the femtogram range and relative isotope ratio uncertainty better than 10% using gadolinium as a surrogate for uranium. In this paper we present measurement results on standard samples containing traces of depleted, natural, and low enriched uranium, as well as measurements on aerodynamic size uranium particles mixed in background materials (e.g., dust, minerals, soils). Improvements and optimizations in the detection electronics, signal timing, calibration, and laser alignment have lead to significant improvements in detection sensitivity and enrichment accuracy, contributing to an overall reduction in the false alarm probability. The sample substrate media was also found to play a significant role in facilitating laser-induced vaporization and the production of energetic plasma conditions, resulting in ablation optimization and further improvements in the isotope abundance sensitivity.

Wax formation assessment of condensate in South Pars gas processing plant sea pipeline (a case study)  

Science Journals Connector (OSTI)

The wax deposition from the gas condensate in South Pars gas processing plant causes a number of severe problems. These problems include: (1) deposits form on the reboiler tubes of stabilizer column and tend to reduce its duty (2) forcing periodic shut-down and removal of deposits (3) interrupting normal processing operations. An understanding of deposition, nature and propensity is necessary to mitigate the mentioned problems. In this work, the multi solid phase model is used to predict the wax precipitation from gas condensate fluid. For five different reservoir fluids, several methods were investigated to split the heavy hydrocarbon fraction into pseudo fractions. The results show that the Al-Meshari method is the most accurate one. Also, a set of consistent correlations were used to calculate the critical points, fusion properties and the acentric factor of the single carbon number groups in the extended composition. Finally the best methods for predicting the wax formation are selected and used to predict the wax formation in the sea line of South Pars gas processing plant. The modeling shows that wax precipitation starts at 293 K and 86 bar. At this pressure and temperature the pipeline is 94 km away from the wellhead.
