Owls  

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

Owls Owls Nature Bulletin No. 267-A April 29, 1967 Forest Preserve District of Cook County Richard B. Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation OWLS The owls, of all our native birds, are least understood. Most kinds remain hidden, motionless and silent during the day and hunt only at night or in the dim twilight of morning and evening. Only a few, like our common Short-eared Owl and those big owls of the far north -- the Snowy Owl, the Great Gray Owl and the Hawk Owl -- habitually hunt in daytime. Because an owl' s feathers are peculiarly soft and fluffy, it flies as silently as a passing shadow, swoops upon its prey unheard, and its Indian name was "hush-wing". Since ancient times there have been many superstitions and legends about these birds. They have been regarded as the companions of sorcerers, witches, ghosts, hobgoblins and Satan himself. Their weird nocturnal hootings, gobblings and screams were and are believed to predict death, illness or disaster. Even today, in our southern states, the plaintive quavering cry of the Little Screech Owl -- which they call the "Shivering" Owl -- will cause some people to get out of bed and turn over their left shoe; others to throw a nail or other iron object into the fire. To the Greeks and Romans, the owl was a symbol of wisdom and was the companion of their goddess of wisdom.

Barred Owl Hooting  

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

Barred Owl Hooting Barred Owl Hooting Name: ray Location: N/A Country: N/A Date: N/A Question: have barred owls ever been known to hoot during the daylight hours? Replies: I spent two years researching barred and horned owls when I was a graduate student and these owls are often found to call during daylight hours. I found both species fairly active at about 3pm and sometimes as late as 10am. The fledglings may be active anytime day and night. Parents are most vocal in the spring when trying to locate young and in the pre-nesting season during January-March. However, the barred owl is most active during the night and many times the calling is dependent upon the time of year [breeding season of November through April is more active for adults in particular]. Yearlings can make calls, noise anytime during the day.

The Screech Owl  

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

Screech Owl Screech Owl Nature Bulletin No. 100 January 25, 1947 Forest Preserve District of Cook County William N. Erickson, President Roberts Mann, Superintendent of Conservation THE SCREECH OWL At the foot of a dead oak where we hoped to find some winter mushrooms beneath the grass and fallen leaves, we spied several pellets about the size and shape of the end of your thumb. They were clean and odorless, each containing the skull and bones of a mouse tightly wrapped in a layer of the animal's fur. Owls and hawks swallow their prey whole or in large pieces and later spit out the indigestible matter in the form of pellets. Up in this tree was a woodpecker hole from which the round unwinking yellow eyes of a screech owl glared at us. A screech owl, about the size of a robin but much chunkier, is our only small owl with ear tufts like "horns". They prey on mice, chipmunks and ground squirrels, fish, crayfish, amphibians, small snakes, angleworms, and large insects. When other food is scarce, and their fuzzy white young -- usually four in number -- require much food, they frequently kill birds but apparently not enough to seriously affect the bird population. No owl, of any species, should be killed.

Nesting Habits of Owls

Nesting Habits of Owls Nesting Habits of Owls Nature Bulletin No. 624 January 14, 1961 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist NESTING HABITS OF OWLS From all of the information available it appears to us that, amongst the owls, there is greater variation in where and how they nest than in any other group of birds. Two nesting characteristics, however, are common to all owls. The eggs are nearly spherical and white, or off-white, without any markings. Also, a nesting female does not lay one egg per day, as most birds do, but at intervals of two or more days -- sometimes several. In extreme cases there may be a fresh egg, others incubating, and a newly hatched fledgling -- all in the same nest.

V.: GLOO: A Graphical Query Language for OWL Ontologies. OWLED  

E-Print Network (OSTI)

Abstract. The database usability experience has shown that visual query languages tend to be superior to textual languages in many aspects. By applying this principle in the context of ontologies, we present GLOO, a graphical query language for OWL-DL ontologies. GLOO maps diagrammatic queries to DL based query languages such as nRQL, which is offered by the OWL-DL reasoner Racer. GLOO hides the complexity of a DL query language from users and allows them to query OWL ontologies with less difficulty. 1

Spotted Inflation  

E-Print Network (OSTI)

We describe new scenarios of generating curvature perturbations when inflaton (curvaton) has significant interactions. We consider a ``spot'', which arises from interactions associated with enhanced symmetric point (ESP) on the trajectory. Our first example uses the spot to induce a gap to the field equation. We observe that the gap in the field equation may cause generation of curvature perturbation if it appears not simultaneous in space. The mechanism is similar to the scenario of inhomogeneous phase transition. Then we observe that the spot interactions may initiate warm inflation in the cold Universe. Creation of cosmological perturbation is discussed in relation to the inflaton dynamics and the modulation associated with the spot interactions.

Natural Gas Spot Prices:  

Gasoline and Diesel Fuel Update (EIA)

4 of 26 4 of 26 Notes: Spot wellhead prices last summer averaged well over $4.00 per thousand cubic feet during a normally low-price season. During the fall, these prices stayed above $5.00 per thousand cubic feet, more than double the year-ago average price. In January, the spot wellhead price averaged a record $8.98 per thousand cubic feet. Spot prices at the wellhead have never been this high for such a prolonged period. The chief reason for these sustained high gas prices was, and still is, uneasiness about the supply situation. Concern about the adequacy of winter supplies loomed throughout most of the summer and fall as storage levels remained significantly depressed. Last December, the most severe assumptions about low storage levels became real, when the spot price

Reactor hot spot analysis  

SciTech Connect

The principle methods for performing reactor hot spot analysis are reviewed and examined for potential use in the Applied Physics Division. The semistatistical horizontal method is recommended for future work and is now available as an option in the SE2-ANL core thermal hydraulic code. The semistatistical horizontal method is applied to a small LMR to illustrate the calculation of cladding midwall and fuel centerline hot spot temperatures. The example includes a listing of uncertainties, estimates for their magnitudes, computation of hot spot subfactor values and calculation of two sigma temperatures. A review of the uncertainties that affect liquid metal fast reactors is also presented. It was found that hot spot subfactor magnitudes are strongly dependent on the reactor design and therefore reactor specific details must be carefully studied. 13 refs., 1 fig., 5 tabs.

Small Spot, Brighter Beam  

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

Small Spot, Brighter Beam Small Spot, Brighter Beam Small Spot, Brighter Beam Print Do you notice the brighter beam? During the most recent shutdown, all of the corrector magnets were replaced with sextupoles, reducing the horizontal emittance and increasing beam brightness. "This is part of ongoing improvement to keep the ALS on the cutting edge," says Alastair MacDowell, a beamline scientist on Beamline 12.2.2. The brightness has increased by a factor of about three in the storage ring. Beamlines on superbend or center-bend magnets will see the most noticeable increase in brightness, but the horizontal beam size and divergence have been substantially reduced at all beamlines. "We are starting to approach the resolution of many beamlines. Therefore, not every beamline will be able to resolve the full improvement," says Christoph Steier, project leader of the brightness upgrade. Though superbend and center-bend magnet source sizes are reduced by roughly a factor of three, "measured improvements so far range from a factor of 2-2.5," Steier says. He and MacDowell agree that the beamline optics are likely the limiting factor in resolving the full improvement at the beamlines.

Natural Gas Spot Price Outlook  

Gasoline and Diesel Fuel Update (EIA)

7 of 17 7 of 17 Notes: Despite signs that domestic natural gas production has begun to turn around (the Texas Railroad Commission now reports year-to-date (through Sep.) gains in Texas gas production of 1.2 percent, compared to a 4.7-percent decline for the same months in 1999 versus 1998) the reality of the U.S. gas market is that supply responses have been too little, too late to prevent record-high spot prices and prospects for very high average prices this winter. We now expect to see peak monthly spot wellhead prices this winter of over $6.00 per thousand cubic feet (mcf) (December). Last month we maintained confidence that conditions would improve enough to keep the $5.10 per mcf recorded in October as the peak for this heating season. With partial data available, a monthly average value of about $5.60 per mcf looks likely for

A.: Defining a benchmark suite for evaluating the import of OWL lite ontologies  

E-Print Network (OSTI)

Abstract. Semantic Web tools should be able to correctly interchange ontologies and, therefore, to interoperate. This interchange is not always a straightforward task if tools have different underlying knowledge representation paradigms. This paper describes the process followed to define a benchmark suite for evaluating the OWL import capabilities of ontology development tools in a benchmarking activity in progress in the Knowledge Web 1 European Network of Excellence. 1

MEXICAN CORN: Genetic Variability and Trade Liberalisation  

E-Print Network (OSTI)

It is now a well established fact that corn (Zea mays) originated in Mexico and that a great part of the evolution that may be observed in terms of this plant’s genetic variability took place in this country. 2 As the plant’s history unfolded, early forms of these races were taken by people into a wide variety of environments and ecological niches from which many distinct varieties developed in the relative isolation of these separated regions. Thus, Mexico also became a center of genetic diversity for corn, and its stock of germplasm has contributed in a decisive manner to global production of corn. Even the dented varieties of the U.S. Corn Belt are close descendants of the first Mexican landraces. The germplasm resources that are deposited in Mexico’s corn varieties, as well as in the wild relatives of this crop, are of prime importance for the world’s food production system of the next century. 3 Corn germplasm of Mexican origin has played a critical role in improvements for corn cultivated in tropical regions in relation to yield increments, plague resistance, short growth cycle, drought resistance and increases of protein content of grain. It has also been instrumental in increasing yields in the case of corn produced in temperate regions at high latitudes. Mexican 1

Spot Distillate & Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: Retail distillate prices follow the spot distillate markets, and crude oil prices have been the main driver behind distillate spot price increases until recently. Crude oil rose about 36 cents per gallon from its low point in mid February 1999 to the middle of January 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, heating oil spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled slightly higher as the New York Harbor market began to

Measuring microfocus focal spots using digital radiography  

SciTech Connect

Measurement of microfocus spot size can be important for several reasons: (1) Quality assurance during manufacture of microfocus tubes; (2) Tracking performance and stability of microfocus tubes; (3) Determining magnification (especially important for digital radiography where the native spatial resolution of the digital system is not adequate for the application); (4) Knowledge of unsharpness from the focal spot alone. The European Standard EN 12543-5 is based on a simple geometrical method of calculating focal spot size from unsharpness of high magnification film radiographs. When determining microfocus focal spot dimensions using unsharpness measurements both signal-to-noise (SNR) and magnification can be important. There is a maximum accuracy that is a function of SNR and therefore an optimal magnification. Greater than optimal magnification can be used but it will not increase accuracy.

Retail Price Changes Lag Spot Prices  

Gasoline and Diesel Fuel Update (EIA)

1 1 Notes: While EIA cannot claim to explain all of the factors that drive retail gasoline prices, we have had a fair amount of success in exploring the relationship between wholesale and retail prices. In particular, we have looked closely at the "pass-through" of changes in spot prices to the retail market. This graph shows a weighted national average of spot prices for regular gasoline -both conventional and reformulated (shown in red), and EIA's weekly survey price for retail regular (again both conventional and reformulated). As you can see, spot prices tend to be more volatile (and would be even more so on a daily basis), while these changes are smoother by the time they reach the retail pump. Furthermore, by looking at the peaks, you can see the retail prices seem to lag the spot price changes

United States -- Mexican joint ventures: A case history approach  

Science Conference Proceedings (OSTI)

Because the Mexican government has encouraged investment in Mexico by increasing the percentage of ownership of a Mexican business that a US company can hold, joint ventures are more attractive now than they had been in the past. This study provides preliminary information for US renewable energy companies who are interested in forming a joint venture with a Mexican company. This report is not intended to be a complete reference but does identifies a number of important factors that should be observed when forming a Mexican joint venture: (1)Successful joint ventures achieve the goals of each partner. (2)It is essential that all parties agree to the allocation of responsibilities. (3)Put everything in writing. (4)Research in depth the country or countries in which you are considering doing business.

Measuring microfocal spots using digital radiography  

SciTech Connect

The European Standard EN 12543-5 is based on a simple geometrical method of calculating focal spot size from unsharpness of high magnification film radiographs. The following equations are used for the focal spot size measurement: By similar triangles the following equations are presupposed: f/a = U/b and M = (a+b)/a. These equations can be combined to yield the well known expression: U = f(M - 1). Solving for f, f = U/(M-1). Therefore, the focal spot size, f, can be calculated by measuring the radiographic unsharpness and magnification of a known object. This is the basis for these tests. The European standard actually uses one-half of the unsharpness (which are then added together) from both sides of the object to avoid additional unsharpness contributions due to edge transmission unsharpness of the round test object (the outside of the object is measured). So the equation becomes f = (1/2 U{sub 1} + 1/2 U{sub 2})/(M-1). In practice 1/2 U is measured from the 50% to the 90% signal points on the transition profile from ''black'' to ''white,'' (positive image) or attenuated to unattenuated portion of the image. The 50% to 90% points are chosen as a best fit to an assumed Gaussian radiation distribution from the focal spot and to avoid edge transmission effects. 1/2 U{sub 1} + 1/2 U{sub 2} corresponds about to the full width at half height of a Gaussian focal spot. A highly absorbing material (Tungsten, Tungsten Alloy, or Platinum) is used for the object. Either wires or a sphere are used as the object to eliminate alignment issues. One possibility is to use the wires in the ASTM E2002 unsharpness gage and take two orthogonal images. The signal levels in the image need to be linear with radiation exposure and so may need conversion if a nonlinear detector is used to acquire the image.

Mexican demand for US natural gas  

SciTech Connect

This study describes the Mexican natural gas industry as it exists today and the factors that have shaped the evolution of the industry in the past or that are expected to influence its progress; it also projects production and use of natural gas and estimates the market for exports of natural gas from the United States to Mexico. The study looks ahead to two periods, a near term (1993--1995) and an intermediate term (1996--2000). The bases for estimates under two scenarios are described. Under the conservative scenario, exports of natural gas from the United States would decrease from the 1992 level of 250 million cubic feet per day (MMCF/d), would return to that level by 1995, and would reach about 980 MMCF/D by 2000. Under the more optimistic scenario, exports would decrease in 1993 and would recover and rise to about 360 MMCF/D in 1995 and to 1,920 MMCF/D in 2000.

Automated Spot Weld Inspection using Infrared Thermography  

Science Conference Proceedings (OSTI)

An automated non-contact and non-destructive resistance spot weld inspection system based on infrared (IR) thermography was developed for post-weld applications. During inspection, a weld coupon was heated up by an auxiliary induction heating device from one side of the weld, while the resulting thermal waves on the other side were observed by an IR camera. The IR images were analyzed to extract a thermal signature based on normalized heating time, which was then quantitatively correlated to the spot weld nugget size. The use of normalized instead of absolute IR intensity was found to be useful in minimizing the sensitivity to the unknown surface conditions and environment interference. Application of the IR-based inspection system to different advanced high strength steels, thickness gauges and coatings were discussed.

Friction Stir Spot Welding of Advanced High Strength Steels  

Science Conference Proceedings (OSTI)

Friction stir spot welding techniques were developed to successfully join several advanced high strength steels. Two distinct tool materials were evaluated to determine the effect of tool materials on the process parameters and joint properties. Welds were characterized primarily via lap shear, microhardness, and optical microscopy. Friction stir spot welds were compared to the resistance spot welds in similar strength alloys by using the AWS standard for resistance spot welding high strength steels. As further comparison, a primitive cost comparison between the two joining processes was developed, which included an evaluation of the future cost prospects of friction stir spot welding in advanced high strength steels.

Exploring variations in the fundamental constants with ELTs: The CODEX spectrograph on OWL  

E-Print Network (OSTI)

Cosmological variations in the fine structure constant, alpha, can be probed through precise velocity measurements of metallic absorption lines from intervening gas clouds seen in spectra of distant quasars. Data from the Keck/HIRES instrument support a variation in alpha of 6 parts per million. Such a variation would have profound implications, possibly providing a window into the extra spatial dimensions required by unified theories such as string/M-theory. However, recent results from VLT/UVES suggest no variation in alpha. The COsmic Dynamics EXperiment (CODEX) spectrograph currently being designed for the ESO OWL telescope (Pasquini et al 2005) with a resolution high enough to properly resolve even the narrowest of metallic absorption lines, R>150,000, will achieve a 2-to-3 order-of-magnitude precision increase in Delta\\alpha/alpha. This will rival the precision available from the Oklo natural fission reactor and upcoming satellite-borne atomic clock experiments. Given the vital constraints on fundamental physics possible, the ELT community must consider such a high-resolution optical spectrograph like CODEX.

Phase-resolved spectroscopy of Geminga shows rotating hot spot(s)  

E-Print Network (OSTI)

Isolated neutron stars are seen in x-rays through their nonthermal and/or surface thermal emissions. XMM-Newton observations of the Geminga pulsar show a 43 electron volt spectrum from the whole neutron star surface, as well as a power-law component above 2 kiloelectron volts. In addition, we have detected a hot (170 electron volts) thermal emission from an 60-meter-radius spot on the pulsar s surface. Such a thermal emission, only visible at selected phase intervals, may be coming from polar hot spot(s), long thought to exist as a result of heating from magnetospheric accelerated particles. It may provide the missing link between the x-ray and gamma-ray emission of the pulsar.

RAS Gene Hot-Spot Mutations in  

E-Print Network (OSTI)

Point mutations in the cellular homologues HRAS, KRAS2, and NRAS of the viral Harvey and Kirsten rat sarcoma virus oncogenes are commonly involved in the onset of malignancies in humans and other species such as dog, mouse, and rat. Most often, three particular hot-spot codons are affected, with one amino acid exchange being sufficient for the induction of tumor growth. While RAS genes have been shown to play an important role in canine tumors such as non-small lung cell carcinomas, data about RAS mutations in canine fibrosarcomas as well as KRAS2 mutations in canine melanomas is sparse. To increase the number of tumors examined, we recently screened 13 canine fibrosarcomas and 11 canine melanomas for point mutations, particularly within the mutational hot spots. The results were compared to the already existing data from other studies about these tumors in dogs. A family of genes often involved in human tumors are the well-characterized RAS genes, which comprise HRAS, KRAS2, and NRAS, coding for closely related, small, 189 amino acid, 21 kDa, membrane-bound, intracellular proteins. The human cellular HRAS and KRAS2 genes were identified to be homologues of the Harvey and Kirsten rat sarcoma

The growth of a natural gas spot market in the United Kingdom (UK) is a radical innovation for the industry. Spot markets turned the oil industry inside out, and will do the same for gas. Such a development seemed all but impossible to gas industry experts three years ago. The role and likely form of a spot market are now at the center of current industry debate about the designing of a daily balancing regime to replace unitary management by British Gas. This paper examines parallels between the evolution of spot markets for oil in the 1980`s and the current UK gas industry. 12 refs., 1 fig.

Foreign firms to get equal opportunity in Mexican selloff plans  

SciTech Connect

Petroleos Mexicanos (Pemex) has not finalized details of its long-awaited petrochemical privatization program. However, the state oil group has made it clear the selloff schedule, due to begin during the next two months, will give equal investment opportunity to foreign firms, dashing the hopes of Mexican groups that they would be given first right of refusal in the privatization program. Meanwhile, Pemex has agreed with Shell Oil on a previously announced refining joint venture involving Shell's 225,000-bbl/day refinery at Deer Park, TX. Under the plan, Pemex will purchase a 50% stake in the refinery and join Shell in a $1-billion upgrade with would enable it to handle more Mexican crude. Sources believe that Shell and other US oil groups are interested in acquiring assets from Pemex Petroquimica.

Dark spot formation relative to ITO surface roughness for polyfluorene  

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

Dark spot formation relative to ITO surface roughness for polyfluorene Dark spot formation relative to ITO surface roughness for polyfluorene devices Title Dark spot formation relative to ITO surface roughness for polyfluorene devices Publication Type Journal Article Year of Publication 2004 Authors Liu, Gao, John B. Kerr, and Stephen G. Johnson Journal Synthetic Metals Volume 144 Pagination 1-6 Keywords dark spot, failure mechanism, interface, ito surface, oled Abstract The failure behaviors of ITO/PEDOT;PSS/polyfluorene/Al devices are different depending on the surface roughness of the sputtered ITO anode film. The spikes on ITO surface are responsible for the initial local shorts of the device, which develop into dark spots very quickly. Indium adsorption is observed on the polymer and Al cathode interface. A chemical etching procedure is used to smoothen the ITO surface without changing the ITO thickness and the sheet resistance. Devices made out of smooth ITO show minimum changes at polymer-cathode interface during operation.

Friction Stir Spot Welding of DP780 Carbon Steel  

Science Conference Proceedings (OSTI)

Friction stir spot welds were made in uncoated and galvannneled DP780 sheets using polycrystalline boron nitride stir tools. The tools were plunged at either a single continuous rate or in two segments consisting of a relatively high rate followed by a slower rate of shorter depth. Welding times ranged from 1-10 s. Increasing tool rotation speed from 800 to 1600 rpm increased strength values. The 2-segment welding procedures also produced higher strength joints. Average lap-shear strengths exceeding 10.3 kN were consistently obtained in 4 s on both the uncoated and the galvannealed DP780. The likelihood of diffusion and mechanical interlocking contributing to bond formation was supported by metallographic examinations. A cost analysis based on spot welding in automobile assembly showed that for friction stir spot welding to be economically competitive with resistance spot welding the cost of stir tools must approach that of resistance spot welding electrode tips.

Cost of being a Mexican immigrant and being a Mexican non-citizen in California and Texas  

E-Print Network (OSTI)

The purpose of this thesis is to examine hourly wage differences across different groups of Mexican-origin workers. First, I assess the cost of foreign-born status by comparing the hourly wages of Mexican immigrant workers with those of native-born Mexican American workers. Second, I assess the cost of non-citizenship status by comparing the hourly wages of non-citizens with those of Mexican-born U.S. naturalized citizens. I also seek to determine if these costs are greater in California than in Texas. The data are drawn from the 2000 5% Public Use Microdata Sample (PUMS) U.S. Census. The results from multiple linear regression analyses show that being an immigrant, particularly a non-citizen immigrant, is associated with lower hourly wages, especially in California. Thus, Mexicanorigin workers, especially those in California, bear dual costs for being foreign-born and not being naturalized citizens. Furthermore, I focus on length of U.S. residence to assess the social and economic impact of the different periods on the costs associated with foreign-born status. First, those who came to the United States before the IRCA of 1986 and a series of California propositions during the 1990s have higher hourly wages than those who arrived later, because of more stable labor market conditions and the effect of the duration of stay in the United States. Second, those who arrived during the last decade have much lower hourly wages because of their disadvantaged labor market contexts.

A procedure to determine the planar integral spot dose values of proton pencil beam spots  

Science Conference Proceedings (OSTI)

Purpose: Planar integral spot dose (PISD) of proton pencil beam spots (PPBSs) is a required input parameter for beam modeling in some treatment planning systems used in proton therapy clinics. The measurement of PISD by using commercially available large area ionization chambers, like the PTW Bragg peak chamber (BPC), can have large uncertainties due to the size limitation of these chambers. This paper reports the results of our study of a novel method to determine PISD values from the measured lateral dose profiles and peak dose of the PPBS. Methods: The PISDs of 72.5, 89.6, 146.9, 181.1, and 221.8 MeV energy PPBSs were determined by area integration of their planar dose distributions at different depths in water. The lateral relative dose profiles of the PPBSs at selected depths were measured by using small volume ion chambers and were investigated for their angular anisotropies using Kodak XV films. The peak spot dose along the beam's central axis (D{sub 0}) was determined by placing a small volume ion chamber at the center of a broad field created by the superposition of spots at different locations. This method allows eliminating positioning uncertainties and the detector size effect that could occur when measuring it in single PPBS. The PISD was then calculated by integrating the measured lateral relative dose profiles for two different upper limits of integration and then multiplying it with corresponding D{sub 0}. The first limit of integration was set to radius of the BPC, namely 4.08 cm, giving PISD{sub RBPC}. The second limit was set to a value of the radial distance where the profile dose falls below 0.1% of the peak giving the PISD{sub full}. The calculated values of PISD{sub RBPC} obtained from area integration method were compared with the BPC measured values. Long tail dose correction factors (LTDCFs) were determined from the ratio of PISD{sub full}/PISD{sub RBPC} at different depths for PPBSs of different energies. Results: The spot profiles were found to have angular anisotropy. This anisotropy in PPBS dose distribution could be accounted in a reasonable approximate manner by taking the average of PISD values obtained using the in-line and cross-line profiles. The PISD{sub RBPC} values fall within 3.5% of those measured by BPC. Due to inherent dosimetry challenges associated with PPBS dosimetry, which can lead to large experimental uncertainties, such an agreement is considered to be satisfactory for validation purposes. The PISD{sub full} values show differences ranging from 1 to 11% from BPC measured values, which are mainly due to the size limitation of the BPC to account for the dose in the long tail regions of the spots extending beyond its 4.08 cm radius. The dose in long tail regions occur both for high energy beams such as 221.8 MeV PPBS due to the contributions of nuclear interactions products in the medium, and for low energy PPBS because of their larger spot sizes. The calculated LTDCF values agree within 1% with those determined by the Monte Carlo (MC) simulations. Conclusions: The area integration method to compute the PISD from PPBS lateral dose profiles is found to be useful both to determine the correction factors for the values measured by the BPC and to validate the results from MC simulations.

Wall and laser spot motion in cylindrical hohlraums  

Science Conference Proceedings (OSTI)

Wall and laser spot motion measurements in empty, propane-filled and plastic (CH)-lined gold coated cylindrical hohlraums were performed on the Omega laser facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)]. Wall motion was measured using axial two-dimensional (2D) x-ray imaging and laser spot motion was perpendicularly observed through a thinned wall using streaked hard x-ray imaging. Experimental results and 2D hydrodynamic simulations show that while empty targets exhibit on-axis plasma collision, CH-lined and propane-filled targets inhibit wall expansion, corroborated with perpendicular streaked imaging showing a slower motion of laser spots.

The Mexican oil sector in the 1980s  

SciTech Connect

During this decade of the 1980s and into the 1990s, the relative participation of hydrocarbons in the energy supply will not be reduced significantly and the contribution of alternative energy sources will be modest in upcoming years. Hence, it is necessary to design and implement policies which will promote energy conservation and savings, both directly and indirectly. Topics discussed include: hydrocarbon participation in the Mexican energy sector, the influence of petroleum on the major macroeconomic variables, perspectives for the 1980s and elements of policy.

Spots, plages, and flares on lambda Andromedae and II Pegasi  

E-Print Network (OSTI)

We present the results of a contemporaneous photometric and spectroscopic monitoring of lambda And and II Peg aimed at investigating the behavior of surface inhomogeneities in the atmospheres of these active stars which have nearly the same temperature but different gravity. The light curves and the modulation of the surface temperature, as recovered from LDRs, are used to map the photospheric spots, while the H-alpha emission has been used as an indicator of chromospheric inhomogeneities. The spot temperatures and sizes were derived from a spot model applied to the contemporaneous light and temperature curves. We find larger and cooler spots on II Peg (T_sp ~ 3600 K) compared to lambda And (T_sp ~ 3900 K); this could be the result of both the different gravity and the higher activity level of the former. Moreover, we find a clear anti-correlation between the H-alpha emission and the photospheric diagnostics. We have also detected a modulation of the intensity of the HeI D_3 line with the star rotation. A rough reconstruction of the 3D structure of their atmospheres has been also performed by applying a spot/plage model to the light and temperature curves and to the H-alpha flux modulation. A close spatial association of photospheric and chromospheric active regions has been found in both stars. Larger and cooler spots have been found on II Peg, the system with the active component of higher gravity and higher activity level. The area ratio of plages to spots seems to decrease when the spots get bigger. Moreover, with the present and literature data, a correlation between the temperature difference Delta_T = T_ph - T_sp and the surface gravity has been also suggested. In addition, a strong flare affecting the H-alpha, the HeI D_3, and the cores of NaI D_1,2 lines has been observed on II Peg.

A measurement concept for hot-spot BRDFs from space  

DOE Green Energy (OSTI)

Several concepts for canopy hot-spot measurements from space have been investigated. The most promising involves active illumination and bistatic detection that would allow hot-spot angular distribution (BRDF) measurements from space in a search-light mode. The concept includes a pointable illumination source, such as a laser operating at an atmospheric window wavelength, coupled with a number of high spatial-resolution detectors that are clustered around the illumination source in space, receiving photons nearly coaxial with the reto-reflection direction. Microwave control and command among the satellite cluster would allow orienting the direction of the laser beam as well as the focusing detectors simultaneously so that the coupled system can function like a search light with almost unlimited pointing capabilities. The concept is called the Hot-Spot Search-Light (HSSL) satellite. A nominal satellite altitude of 600 km will allow hot-spot BRDF measurements out to about 18 degrees phase angle. The distributed are taking radiometric measurements of the intensity wings of the hot-spot angular distribution without the need for complex imaging detectors. The system can be operated at night for increased signal-to-noise ratio. This way the hot-spot angular signatures can be quantified and parameterized in sufficient detail to extract the biophysical information content of plant architectures.

New Mexican taxes to transform Pemex capital spending strategy  

SciTech Connect

Mexico's government this year will introduce petroleum tax reforms that will transform how its state owned petroleum company approaches capital spending. Effective Jan. 1, 1994, the Mexican government began to implement a revamped tax regime designed to accompany the breakup of Petroleos Mexicanos into four new operating subsidiaries. Each of the four new companies -- Pemex Exploration and Production, Pemex Refining, Pemex Natural Gas and Basic Petrochemicals, and Pemex Secondary Petrochemicals -- will be responsible for paying a new income tax. Levies on E and P will be tied to a ring-fence mechanism tailored after the scheme employed by the U.K. and Norwegian governments in the North Sea. The paper discusses the affected investment rationale, the North Sea ring-fence model, other tax changes, and shifting the burden.

The Mexican petrochemical sector in the NAFTA negotiations  

Science Conference Proceedings (OSTI)

Since 1985, there have been important changes in the Mexican petrochemical sector, including trade liberalization, deregulation and the elimination of subsidies. NAFTA represents another step towards liberalization of the sector. Given the low tariffs currently applied to international trade among the three nations, the authors do not anticipate major impacts of NAFTA on trade flows. Nevertheless, the elimination of restrictions to foreign investment is expected to increase capital flows into the sector and to promote productivity increases. On the other hand, the new barriers to trade in petrochemical feedstocks and the restrictions on private investment in infrastructure may negatively affect the sector`s growth, making it necessary to adjust domestic regulations to improve the performance of Pemex. 12 refs., 4 tabs.

UMTRA Project Site Observational Work Plan, Mexican Hat, Utah  

SciTech Connect

Surface cleanup activities at the Mexican Hat UMTRA processing site are nearing completion. Ground Water contamination at the Mexican Hat site is a result of uranium milling operations. The extent of residual process water has been identified, and it is limited to the uppermost aquifer in the vicinity of the site. Deeper aquifers are not affected because of an upward hydraulic gradient and the presence of a confining unit (the deeper aquifers are protected by hydrogeologic isolation). The uppermost unit is returning to its pre-milling, mainly unsaturated state. The unit that contains the contaminated water is not a ground water resource because it qualifies as Class III (limited use) based on limited yield. Ground water in the uppermost unit is currently not used and is not anticipated to be used as a ground water resource. The nearby San Juan River and a converted oil exploration well provide all of the water needs for the area. There are no current threats to human health or livestock; and, because the zone of contamination does not represent a ground water resource, none are anticipated in the future. There are, however, seeps where contaminated water is exposed at land surface. The seeps create potential exposure pathways for plants and wildlife. It is not known at this time if there is a risk to the environment. Additional investigations are needed and are described in this document to confirm the presence or absence of potential environmental risks. Additional hydrogeologic investigations are not required. The proposed ground water compliance strategy for the site is no remediation, because the ground water in the uppermost aquifer (which is also the zone of contamination) qualifies for supplemental standards based on Class III, limited yield, and because there are no threats to human health. Domestic and agricultural water is pumped from a deeper aquifer that is isolated from the contaminated zone.

Simulations of Electron Transport in Laser Hot Spots  

Science Conference Proceedings (OSTI)

Simulations of electron transport are carried out by solving the Fokker-Planck equation in the diffusive approximation. The system of a single laser hot spot, with open boundary conditions, is systematically studied by performing a scan over a wide range of the two relevant parameters: (1) Ratio of the stopping length over the width of the hot spot. (2) Relative importance of the heating through inverse Bremsstrahlung compared to the thermalization through self-collisions. As for uniform illumination [J.P. Matte et al., Plasma Phys. Controlled Fusion 30 (1988) 1665], the bulk of the velocity distribution functions (VDFs) present a super-Gaussian dependence. However, as a result of spatial transport, the tails are observed to be well represented by a Maxwellian. A similar dependence of the distributions is also found for multiple hot spot systems. For its relevance with respect to stimulated Raman scattering, the linear Landau damping of the electron plasma wave is estimated for such VD Fs. Finally, the nonlinear Fokker-Planck simulations of the single laser hot spot system are also compared to the results obtained with the linear non-local hydrodynamic approach [A.V. Brantov et al., Phys. Plasmas 5 (1998) 2742], thus providing a quantitative limit to the latter method: The hydrodynamic approach presents more than 10% inaccuracy in the presence of temperature variations of the order delta T/T greater than or equal to 1%, and similar levels of deformation of the Gaussian shape of the Maxwellian background.

New Mexicans` perceptions of Los Alamos National Laboratory. Final report  

SciTech Connect

Since May, 1990, the Institute for Public Policy (IPP) has published Quarterly Profiles (QPs) of New Mexico`s citizenry. Each QP has focused on a different issue, but they have all asked a set of standard items, including questions about the public`s perceptions of the Los Alamos National Laboratories (LANL). Each year, the IPP has used the University of New Mexico`s Survey Research Center to conduct a telephone survey of a representative random sample of New Mexicans, and respondents were asked whether they had favorable or unfavorable views of LANL and the degree to which they perceived LANL as an environmentally responsible institution. As a result of this sustained research effort, the IPP now has a collection of fifteen consecutive QPs. With an aggregate sample size of over 8800, we are now able to make precise statistical inferences with greater confidence than was possible when using individual QP samples. Such an extremely large sample mitigates two kinds of common survey research problems.

Forecasting Crude Oil Spot Price Using OECD Petroleum Inventory  

Gasoline and Diesel Fuel Update (EIA)

Forecasting Forecasting Crude Oil Spot Price Using OECD Petroleum Inventory Levels MICHAEL YE, ∗ JOHN ZYREN, ∗∗ AND JOANNE SHORE ∗∗ Abstract This paper presents a short-term monthly forecasting model of West Texas Intermedi- ate crude oil spot price using OECD petroleum inventory levels. Theoretically, petroleum inventory levels are a measure of the balance, or imbalance, between petroleum production and demand, and thus provide a good market barometer of crude oil price change. Based on an understanding of petroleum market fundamentals and observed market behavior during the post-Gulf War period, the model was developed with the objectives of being both simple and practical, with required data readily available. As a result, the model is useful to industry and government decision-makers in forecasting price and investigat- ing the impacts of changes on price, should inventories,

Joint Modelling of Gas and Electricity spot prices  

E-Print Network (OSTI)

The recent liberalization of the electricity and gas markets has resulted in the growth of energy exchanges and modelling problems. In this paper, we modelize jointly gas and electricity spot prices using a mean-reverting model which fits the correlations structures for the two commodities. The dynamics are based on Ornstein processes with parameterized diffusion coefficients. Moreover, using the empirical distributions of the spot prices, we derive a class of such parameterized diffusions which captures the most salient statistical properties: stationarity, spikes and heavy-tailed distributions. The associated calibration procedure is based on standard and efficient statistical tools. We calibrate the model on French for electricity and on UK market for gas, and then simulate some trajectories which reproduce well the observed prices behavior. Finally, we illustrate the importance of the correlation structure and of the presence of spikes by measuring the risk on a power plant portfolio.

When the gasoline market is tight, it affects the portion of gasoline price is the spread between spot product price and crude oil price. Note that in late 1998-and early 1999 spreads were very small when inventories were quite high. Contrast summers of 1998 or 1999 with summer 2000. Last summer's tight markets, resulting low stocks and transition to Phase 2 RFG added price pressure over and above the already high crude price pressure on gasoline -- particularly in the Midwest. As we ended last winter, gasoline inventories were low, and the spread between spot prices and crude oil were higher than typical as a result. Inventories stayed well below average and the spread during the

Radiologic characterization of the Mexican Hat, Utah, uranium mill tailings remedial action site: Addendum D1  

Science Conference Proceedings (OSTI)

This radiologic characterization of the inactive uranium millsite at Mexican Hat, Utah, was conducted by Bendix Field Engineering Corporation for the US Department of Energy (DOE), Grand Junctions Project Office in response to and in accord with a Statement of Work prepared by the DOE Uranium Mill Tailings Remedial Action Project (UMTRAP) Technical Assistance Contractor, Jacobs Engineering Group, Inc. The objective of this project was to determine the horizontal and vertical extent of contamination that exceeds the US Environmental Protection Agency (EPA) standards at the Mexican Hat site. The data presented in this report are required for characterization of the areas adjacent to the Mexican Hat tailings piles and for the subsequent design of cleanup activities. Some on- pile sampling was required to determine the depth of the 15-pCi/g Ra- 226 interface in an area where wind and water erosion has taken place.

Homing in on sweet spots in Cretaceous Austin chalk  

SciTech Connect

In discussing the nature and causes of fracturing in the Cretaceous Austin chalk of south central Texas, many geologists and operators involved in horizontal drilling of the chalk consider regional rock stress as the probable main cause of the fractures. If Austin chalk fractures are mainly the result of regional extensional stress without localizing factors, then fractured sweet spots are randomly distributed and successful exploration is more or less a matter of luck, usually dependent upon the coincidental placement of a seismic line. But if local, deep-seated structure or basement topography are the main causes of sweet spots, then a successful exploration method would be to first delineate the basement paleo structure or topography and secondly, place a seismic line to confirm the delineated features. Finding localities of maximum fracturing and production would than be based on scientific logic rather than luck. It is the purpose of this article to present the results of an examination of these alternative causes for the Austin chalk fracturing in the hope of determining the most cost effective exploration method for the fractured chalk reservoir.

Diode magnetic-field influence on radiographic spot size  

Science Conference Proceedings (OSTI)

Flash radiography of hydrodynamic experiments driven by high explosives is a well-known diagnostic technique in use at many laboratories. The Dual-Axis Radiography for Hydrodynamic Testing (DARHT) facility at Los Alamos was developed for flash radiography of large hydrodynamic experiments. Two linear induction accelerators (LIAs) produce the bremsstrahlung radiographic source spots for orthogonal views of each experiment ('hydrotest'). The 2-kA, 20-MeV Axis-I LIA creates a single 60-ns radiography pulse. For time resolution of the hydrotest dynamics, the 1.7-kA, 16.5-MeV Axis-II LIA creates up to four radiography pulses by slicing them out of a longer pulse that has a 1.6-{micro}s flattop. Both axes now routinely produce radiographic source spot sizes having full-width at half-maximum (FWHM) less than 1 mm. To further improve on the radiographic resolution, one must consider the major factors influencing the spot size: (1) Beam convergence at the final focus; (2) Beam emittance; (3) Beam canonical angular momentum; (4) Beam-motion blur; and (5) Beam-target interactions. Beam emittance growth and motion in the accelerators have been addressed by careful tuning. Defocusing by beam-target interactions has been minimized through tuning of the final focus solenoid for optimum convergence and other means. Finally, the beam canonical angular momentum is minimized by using a 'shielded source' of electrons. An ideal shielded source creates the beam in a region where the axial magnetic field is zero, thus the canonical momentum zero, since the beam is born with no mechanical angular momentum. It then follows from Busch's conservation theorem that the canonical angular momentum is minimized at the target, at least in principal. In the DARHT accelerators, the axial magnetic field at the cathode is minmized by using a 'bucking coil' solenoid with reverse polarity to cancel out whatever solenoidal beam transport field exists there. This is imperfect in practice, because of radial variation of the total field across the cathode surface, solenoid misalignments, and long-term variability of solenoid fields for given currents. Therefore, it is useful to quantify the relative importance of canonical momentum in determining the focal spot, and to establish a systematic methodology for tuning the bucking coils for minimum spot size. That is the purpose of this article. Section II provides a theoretical foundation for understanding the relative importance of the canonical momentum. Section III describes the results of simulations used to quantify beam parameters, including the momentum, for each of the accelerators. Section IV compares the two accelerators, especially with respect to mis-tuned bucking coils. Finally, Section IV concludes with a methodology for optimizing the bucking coil settings.

Transformation from spots to waves in a model of actin pattern formation  

E-Print Network (OSTI)

Actin networks in certain single-celled organisms exhibit a complex pattern-forming dynamics that starts with the appearance of static spots of actin on the cell cortex. Spots soon become mobile, executing persistent random walks, and eventually give rise to traveling waves of actin. Here we describe a possible physical mechanism for this distinctive set of dynamic transformations, by equipping an excitable reaction-diffusion model with a field describing the spatial orientation of its chief constituent (which we consider to be actin). The interplay of anisotropic actin growth and spatial inhibition drives a transformation at fixed parameter values from static spots to moving spots to waves.

Electrophoretic extraction of proteins from two-dimensional electrophoresis gel spots  

DOE Patents (OSTI)

After two-dimensional electrophoresis of proteins or the like, resulting in a polyacrylamide gel slab having a pattern of protein gel spots thereon, an individual protein gel spot is cored out from the slab, to form a gel spot core which is placed in an extraction tube, with a dialysis membrane across the lower end of the tube. Replicate gel spots can be cored out from replicate gel slabs and placed in the extraction tube. Molten agarose gel is poured into the extraction tube where the agarose gel hardens to form an immobilizing gel, covering the gel spot cores. The upper end portion of the extraction tube is filled with a volume of buffer solution, and the upper end is closed by another dialysis membrane. Upper and lower bodies of a buffer solution are brought into contact with the upper and lower membranes and are provided with electrodes connected to the positive and negative terminals of a DC power supply, thereby producing an electrical current which flows through the upper membrane, the volume of buffer solution, the agarose, the gel spot cores and the lower membrane. The current causes the proteins to be extracted electrophoretically from the gel spot cores, so that the extracted proteins accumulate and are contained in the space between the agarose gel and the upper membrane. A high percentage extraction of proteins is achieved. The extracted proteins can be removed and subjected to partial digestion by trypsin or the like, followed by two-dimensional electrophoresis, resulting in a gel slab having a pattern of peptide gel spots which can be cored out and subjected to electrophoretic extraction to extract individual peptides.

Avoiding Carbon Bed Hot Spots in Thermal Process Off-Gas Systems  

Science Conference Proceedings (OSTI)

Mercury has had various uses in nuclear fuel reprocessing and other nuclear processes, and so is often present in radioactive and mixed (radioactive and hazardous) wastes. Test programs performed in recent years have shown that mercury in off-gas streams from processes that treat radioactive wastes can be controlled using fixed beds of activated sulfur-impregnated carbon, to levels low enough to comply with air emission regulations such as the Hazardous Waste Combustor (HWC) Maximum Achievable Control Technology (MACT) standards. Carbon bed hot spots or fires have occurred several times during these tests, and also during a remediation of tanks that contained mixed waste. Hot spots occur when localized areas in a carbon bed become heated to temperatures where oxidation occurs. This heating typically occurs due to heat of absoption of gas species onto the carbon, but it can also be caused through external means such as external heaters used to heat the carbon bed vessel. Hot spots, if not promptly mitigated, can grow into bed fires. Carbon bed hot spots and fires must be avoided in processes that treat radioactive and mixed waste. Hot spots are detected by (a) monitoring in-bed and bed outlet gas temperatures, and (b) more important, monitoring of bed outlet gas CO concentrations. Hot spots are mitigated by (a) designing for appropriate in-bed gas velocity, for avoiding gas flow maldistribution, and for sufficient but not excessive bed depth, (b) appropriate monitoring and control of gas and bed temperatures and compositions, and (c) prompt implementation of corrective actions if bed hot spots are detected. Corrective actions must be implemented quickly if bed hot spots are detected, using a graded approach and sequence starting with corrective actions that are simple, quick, cause the least impact to the process, and are easiest to recover from.

The anode spot plasma ion source (ASPIS) has been investigated as a high brightness ion source for nano applications such as focused ion beam (FIB) and nano medium energy ion scattering (nano-MEIS). The generation of anode spot is found to enhance brightness of ion beam since the anode spot increases plasma density near the extraction aperture. Brightness of the ASPIS has been estimated from measurement of emittance for total ion beam extracted through sub-mm aperture. The ASPIS is installed to the FIB system. Currents and diameters of the focused beams with/without anode spot are measured and compared. As the anode spot is turned on, the enhancement of beam current is observed at fixed diameter of the focused ion beam. Consequently, the brightness of the focused ion beam is enhanced as well. For argon ion beam, the maximum normalized brightness of 12 300 A/m{sup 2} SrV is acquired. The ASPIS is applied to nano-MEIS as well. The ASPIS is found to increase the beam current density and the power efficiency of the ion source for nano-MEIS. From the present study, it is shown that the ASPIS can enhance the performance of devices for nano applications.

USING STAR SPOTS TO MEASURE THE SPIN-ORBIT ALIGNMENT OF TRANSITING PLANETS  

SciTech Connect

Spectroscopic follow-up of dozens of transiting planets has revealed the degree of alignment between the equators of stars and the orbits of the planets they host. Here we determine a method, applicable to spotted stars, that can reveal the same information from the photometric discovery data, with no need for follow-up. A spot model fit to the global light curve, parameterized by the spin orientation of the star, predicts when the planet will transit the spots. Observing several spot crossings during different transits then leads to constraints on the spin-orbit alignment. In cases where stellar spots are small, the stellar inclination, i{sub s} , and hence the true alignment, rather than just the sky projection, can be obtained. This method has become possible with the advent of space telescopes such as CoRoT and Kepler, which photometrically monitor transiting planets over a nearly continuous, long time baseline. We apply our method to CoRoT-2 and find the projected spin-orbit alignment angle, {lambda} = 4.{sup 0}7 {+-} 12.{sup 0}3, in excellent agreement with a previous determination that employed the Rossiter-McLaughlin effect. The large spots of the parent star, CoRoT-2, limit our precision on i{sub s} : 84{sup 0} {+-} 36{sup 0}, where i{sub s} < 90{sup 0}(> 90{sup 0}) indicates that the rotation axis is tilted toward (away from) the line of sight.

Characterization of plasma and laser conditions for single hot spot interaction experiments  

Science Conference Proceedings (OSTI)

The LANL TRIDENT laser system is being used for fundamental experiments which study the interaction of self-focusing, stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) in a single (diffraction limited) laser hot spot in order to better understand the coupling between these plasma instabilities. The diffraction limited beam mimics a single hot spot found in speckle distributions that are typical of random or kinoform phase plate (RPP or KPP) smoothing. A long scale length, hot plasma ({approximately} 1 mm, {approximately} 0.5 keV) is created by a separate heater beam, and the single hot spot beam is used to drive parametric instabilities. The focal plane distribution and wavefront of the single hot spot beam are characterized, and the intensity of the single hot spot can be varied between 10{sup 14}--10{sup 16} W/cm{sup 2}. The plasma density, temperature, and flow profiles are measured using gated imaging spectroscopy of collective Thomson scattering. Results of the laser and plasma characterization, and initial results of backscattered SRS, SBS, and beam steering in a flowing plasma are presented.

Uniform irradiation of adjustable target spots in high-power laser driver  

Science Conference Proceedings (OSTI)

For smoothing and shaping the on-target laser patterns flexibly in high-power laser drivers, a scheme has been developed that includes a zoom lens array and two-dimensional smoothing by spectral dispersion (SSD). The size of the target pattern can be controlled handily by adjusting the focal length of the zoom lens array, while the profile of the pattern can be shaped by fine tuning the distance between the target and the focal plane of the principal focusing lens. High-frequency stripes inside the pattern caused by beamlet interference are wiped off by spectral dispersion. Detailed simulations indicate that SSD works somewhat differently for spots of different sizes. For small spots, SSD mainly smooths the intensity modulation of low-to-middle spatial frequency, while for large spots, SSD sweeps the fine speckle structure to reduce nonuniformity of middle-to-high frequency. Spatial spectra of the target patterns are given and their uniformity is evaluated.

Development of the Dried Spot Sample Preparation Methodology and Applications to XRMF Analysis  

Science Conference Proceedings (OSTI)

The dried spot method has significant potential for trace elemental analysis using x-ray fluorescence. Small sample size coupled with spatially resolved excitation offers increased sensitivity for aqueous solutions. The primary limitation in applying this method to routine analyses is that much of the method development and fundamental aspects have not been investigated. We have studied the effects of a number of parameters on the quantitative capabilities of the dried spot method. These include thin-film substrates, drying methods, and solution composition. The small sample size offers opportunities for the analysis of a wide array of sample types including highly radioactive specimens.

Networks in the modern economy: Mexican migrants in the u.s. labor market  

E-Print Network (OSTI)

This paper attempts to identify job networks among Mexican migrants in the U. S. labor market. The empirical analysis uses data on migration patterns and labor market outcomes, based on a sample of individuals belonging to multiple origin-communities in Mexico, over a long period of time. Each community’s network is measured by the proportion of the sampled individuals who are located at the destination (the United States) in any year. We verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger, by including individual ?xed effects in the employment and occupation regressions and by using rainfall in the origin-community as an instrument for the size of the network at the destination.

Assessment of the radiological impact of the inactive uranium-mill tailings at Mexican Hat, Utah  

SciTech Connect

High surface soil concentrations of /sup 226/Ra and high above-ground measurements of gamma-ray intensity in the vicinity of the inactive uranium-mill tailings at Mexican Hat show both wind and water erosion of the tailings. The former mill area, occupied by a trade school at the time of this survey, shows a comparatively high level of contamination, probably from unprocessed ore on the surface of the ore storage area near the location of the former mill buildings. However, the estimated health effect of exposure to gamma rays during a 2000-hr work year in the area represents an increase of 0.1% in the risk of death from cancer. Exposure of less than 600 persons within 1.6 km of the tailings to radon daughters results in an estimated 0.2%/year increase in risk of lung cancer.

Latinas in the city: a discussion of how young Mexican women identify and engage with Sex and the City  

E-Print Network (OSTI)

Globalization trends and treaties, such as the North American Free Trade Agreement (NAFTA), have increased the access and flow of United States media and popular culture products in Mexico. Limited research has been done examining the exposure of Mexican audiences to U.S. media products and the possibility of mass media’s impact on Mexican cultural identity. This qualitative study examines how twenty college-educated Mexican women identify and engage with the transnational popular culture text of Sex and the City (SATC). A multi-disciplinary theoretical approach, mainly from cultural studies and media studies, provides the backbone for my study of a foreign audience’s identification and engagement with a U.S. popular culture text. Thematic categorization of my interview data showed that genre, gender, class and location all played a role in the media engagement process. SATC enabled these twenty women to examine their lived experiences in Mexican society and be exposed to alternative viewpoints. The women interviewed were active audience members that discussed their experiences as college-educated, career driven women associated with modernity but living in the traditional, patriarchal society of Mexico. The women interviewed preferred watching television from other countries, such as the U.S., because it resonated with their lived experiences more than the telenovelas, which are the most common form of television programming in Latin America. In terms of discussing the representation of women on SATC, women talked about the gender roles, myths and structural forces of Mexican society to engage in resistive pleasure and to talk about gender politics. For these Mexican women, discussing SATC allowed them to express concerns over the representation of women in telenovelas, the importance of having alternative viewpoints available to women, and the experiences that have allowed them to foster spaces for change based on SATC’s content and characters. While factors, such as education, socioeconomics and geographic location framed the respondent comments, SATC was a source of strategic knowledge and cultural capital for women to open up new discussions with friends and family, new ways of looking and living out their sexuality, and ideas of the female body.

Hot-spot mix in ignition-scale implosions on the NIF  

Science Conference Proceedings (OSTI)

Ignition of an inertial confinement fusion (ICF) target depends on the formation of a central hot spot with sufficient temperature and areal density. Radiative and conductive losses from the hot spot can be enhanced by hydrodynamic instabilities. The concentric spherical layers of current National Ignition Facility (NIF) ignition targets consist of a plastic ablator surrounding a thin shell of cryogenic thermonuclear fuel (i.e., hydrogen isotopes), with fuel vapor filling the interior volume [S. W. Haan et al., Phys. Plasmas 18, 051001 (2011)]. The Rev. 5 ablator is doped with Ge to minimize preheat of the ablator closest to the DT ice caused by Au M-band emission from the hohlraum x-ray drive [D. S. Clark et al., Phys. Plasmas 17, 052703 (2010)]. Richtmyer-Meshkov and Rayleigh-Taylor hydrodynamic instabilities seeded by high-mode () ablator-surface perturbations can cause Ge-doped ablator to mix into the interior of the shell at the end of the acceleration phase [B. A. Hammel et al., Phys. Plasmas 18, 056310 (2011)]. As the shell decelerates, it compresses the fuel vapor, forming a hot spot. K-shell line emission from the ionized Ge that has penetrated into the hot spot provides an experimental signature of hot-spot mix. The Ge emission from tritium-hydrogen-deuterium (THD) and deuterium-tritium (DT) cryogenic targets and gas-filled plastic-shell capsules, which replace the THD layer with a mass-equivalent CH layer, was examined. The inferred amount of hot-spot-mix mass, estimated from the Ge K-shell line brightness using a detailed atomic physics code [J. J. MacFarlane et al., High Energy Density Phys. 3, 181 (2006)], is typically below the 75-ng allowance for hot-spot mix [S. W. Haan et al., Phys. Plasmas 18, 051001 (2011)]. Predictions of a simple mix model, based on linear growth of the measured surface-mass modulations, are consistent with the experimental results.

Phthalate exposure associated with self-reported diabetes among Mexican women  

SciTech Connect

Background: Phthalates are ubiquitous industrial chemicals used as plasticizers in plastics made of polyvinyl chloride (PVC) to confer flexibility and durability. They are also present in products used for personal-care, industry and in medical devices. Phthalates have been associated with several adverse health effects, and recently it has been proposed that exposure to phthalates, could have an effect on metabolic homeostasis. This exploratory cross-sectional study evaluated the possible association between phthalate exposure and self-reported diabetes among adult Mexican women. Methods: As part of an on-going case-control study for breast cancer, only controls were selected, which constituted 221 healthy women matched by age ({+-}5 years) and place of residence with the cases. Women with diabetes were identified by self-report. Urinary concentrations of nine phthalate metabolites were measured by online solid phase extraction coupled to high performance liquid chromatography-isotope-dilution tandem mass spectrometry. Results: Participants with diabetes had significantly higher concentrations of di(2-ethylhexyl) pththalate (DEHP) metabolites: mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono(2-ethyl-5-carboxypentyl) phthalate (MECPP) but lower levels of monobenzyl phthalate (MBzP) a metabolite of benzylbutyl phthalate, compared to participants without diabetes. A marginally significant positive associations with diabetes status were observed over tertiles with MEHHP (OR{sub T3vs.T1}=2.66; 95% CI: 0.97-7.33; p for trend=0.063) and MEOHP (OR{sub T3vs.T1}=2.27; 95% CI; 0.90-5.75; P for trend=0.079) even after adjusting for important confounders. Conclusions: The results suggest that levels of some phthalates may play a role in the genesis of diabetes. - Highlights: {yields} This study evaluated phthalate exposure and diabetes status among Mexican women. {yields} Urinary phthalates metabolite concentrations were used to determine association. {yields} Participants with diabetes had higher concentrations of three DEHP metabolites. {yields} A positive association with diabetes status was found with MEHHP and MEOHP metabolites. {yields} Results suggest phthalate exposure can have a role in diabetes.

The Determinants of Homeonwership in Presence of Shocks Experienced by Mexican Households  

E-Print Network (OSTI)

Homeownership is both an individual and society objective, because of the positive neighborhood effects associated with areas of higher homeownership. To help realize these positive effects, the Mexican government has several programs directed to increasing homeownership. Many factors, however, may influence homeownership including shocks experienced by households. Shocks such as death in family, illness or accidents, unemployment, and business, crop, or livestock loss affect homeownership if households are unable to cushion the impact of the shock. Government income support programs, however, may help cushion the effect of a shock. The main objective is to determine how shocks that households’ experience and government income support programs influence homeownership in Mexico. A secondary objective is to determine how socio-demographic variables influence homeownership in Mexico. Based on the Random Utility Model, logit models of homeownership are estimated using data are from the 2002 Mexican National Survey on Living Levels of Households. Two models are estimated; with and without income. Income is excluded because of a large number of households that did not report income. Generally, inferences from the two models are similar. Homeownership appears to not be affected by shocks experienced by households. It appears households are able to cushion the impact of shocks. The two income support programs, the Program of Direct Rural Support of Mexico (PROGRESA) and the Program of Direct Rural Support of Mexico (PROCAMPO), appear to be increasing homeownership. These social welfare programs provide cash transfers to households. For whatever reason, PROGRESA has a larger effect on homeownership than PROCAMPO. Households with older heads have a larger probability of being a homeowner than households with younger heads. No statistically significance relationship exists between education and homeownership. Regional differences are seen in homeownership, with households located in the northwest region having a higher probability of homeownership than other regions. Differences in the significance of variable representing the household head’s gender, marital status, and occupation on homeownership exist between logit models that include and do not include current income. The most likely reason for these differences is interactions between the variables and a wealth effect.

Magnetism, chemical spots, and stratification in the HgMn star phi Phoenicis  

E-Print Network (OSTI)

Mercury-manganese (HgMn) stars have been considered as non-magnetic and non-variable chemically peculiar (CP) stars for a long time. However, recent discoveries of the variability in spectral line profiles suggested an inhomogeneous surface distribution of chemical elements in some HgMn stars. From the studies of other CP stars it is known that magnetic field plays a key role in the formation of surface spots. All attempts to find magnetic fields in HgMn stars yielded negative results. In this study, we investigate a possible presence of the magnetic field in phi Phe (HD 11753) and reconstruct surface distribution of chemical elements that show variability in spectral lines. We also test a hypothesis that magnetic field is concentrated in chemical spots and look into the possibility that some chemical elements are stratified with depth in the stellar atmosphere.

CoolSpots enable a wireless mobile device to automatically switch between multiple radio interfaces, such as WiFi and Bluetooth, in order to increase battery lifetime. The main contribution of this work is an exploration of the policies that enable a system to switch among these interfaces, each with diverse radio characteristics and different ranges, in order to save power – supported by detailed quantitative measurements. The system and policies do not require any changes to the mobile applications themselves, and changes required to existing infrastructure are minimal. Results are reported for a suite of commonly used applications, such as file transfer, web browsing, and streaming media, across a range of operating conditions. Experimental validation of the CoolSpot system on a mobile research platform shows substantial energy savings: more than a 50 % reduction in energy consumption of the wireless subsystem is possible, with an associated increase in the effective battery lifetime.

Point and Interval Forecasting of Spot Electricity Prices: Linear vs. Non-Linear Time Series Models  

E-Print Network (OSTI)

In this paper we assess the short-term forecasting power of different time series models in the electricity spot market. In particular we calibrate AR/ARX (”X” stands for exogenous/fundamental variable — system load in our study), AR/ARX-GARCH, TAR/TARX and Markov regime-switching models to California Power Exchange (CalPX) system spot prices. We then use them for out-ofsample point and interval forecasting in normal and extremely volatile periods preceding the market crash in winter 2000/2001. We find evidence that (i) non-linear, threshold regime-switching (TAR/TARX) models outperform their linear counterparts, both in point and interval forecasting, and that (ii) an additional GARCH component generally decreases point forecasting efficiency. Interestingly, the former result challenges a number of previously published studies on the failure of non-linear regime-switching models in forecasting.

Spot pricing of electricity and ancillary services in a competitive California market  

Science Conference Proceedings (OSTI)

Typically, in competitive electricity markets, the vertically integrated utilities that were responsible for ensuring system reliability in their own service territories, or groups of territories, cease to exist. The burden falls to an independent system operator (ISO) to ensure that enough ancillary services (AS) are available for safe, stable, and reliable operation of the grid, typically defined, in part, as compliance with officially approved engineering specifications for minimum levels of AS. In order to characterize the behavior of market participants (generators, retailers, and an ISO) in a competitive electricity market with reliability requirements, spot markets for both electricity and AS are modeled. By assuming that each participant seeks to maximize its wealth and that all markets clear, we solve for the optimal quantities of electricity and AS traded in the spot market by all participants, as well as the market clearing prices for each.

Two self-referencing methods for the measurement of beam spot position  

Science Conference Proceedings (OSTI)

Purpose: Two quantitative methods of measuring electron beam spot position with respect to the collimator axis of rotation (CAOR) are described. Methods: Method 1 uses a cylindrical ion chamber (IC) mounted on a jig corotational with the collimator making the relationship among the chamber, jaws, and CAOR fixed and independent of collimator angle. A jaw parallel to the IC axis is set to zero and the IC position adjusted so that the IC signal is approximately 50% of the open field value, providing a large dose gradient in the region of the IC. The cGy/MU value is measured as a function of collimator rotation, e.g., every 30 Degree-Sign . If the beam spot does not lie on the CAOR, the signal from the ion chamber will vary with collimator rotation. Based on a measured spatial sensitivity, the distance of the beam spot from the CAOR can be calculated from the IC signal variation with rotation. The 2nd method is image based. Two stainless steel rods, 3 mm in diameter, are mounted to a jig attached to the Linac collimator. The rods, offset from the CAOR, lay in different planes normal to the CAOR, one at 158 cm SSD and the other at 70 cm SSD. As the collimator rotates the rods move tangent along an envelope circle, the centers of which are on the CAOR in their respective planes. Three images, each at a different collimator rotation, containing the shadows of both rods, are acquired on the Linac EPID. At each angle the shadow of the rods on the EPID defines lines tangent to the projection of the envelope circles. From these the authors determine the projected centers of the two circles at different heights. From the distance of these two points using the two heights and the source to EPID distance, the authors calculate the distance of the beam spot from the CAOR. Measurements with all two techniques were performed on an Elekta Linac. Measurements were performed with the beam spot in nominal clinical position and in a deliberately offset position. Measurements were also performed using the Flexmap image registration/ball-bearing test. Results: Within their uncertainties, both methods report the same beam spot displacement. In clinical use, a total of 203 monthly beam spot measurements on 14 different beams showed an average displacement of 0.11 mm ({sigma}= 0.07 mm) in-plane and 0.10 mm ({sigma}= 0.07 mm) cross-plane with maximum displacement of 0.37 mm in-plane and 0.34 mm cross-plane. Conclusions: The methods described provide a quantitative measure of beam spot position, are easy to use, and provide another tool for Linac setup and quality assurance. Fundamental to the techniques is that they are self-referencing-i.e., they do not require the user to independently define the CAOR.

Friction Stir Spot Welding (FSSW) of Advanced High Strength Steel (AHSS)  

Science Conference Proceedings (OSTI)

Friction stir spot welding (FSSW) is applied to join advanced high strength steels (AHSS): galvannealed dual phase 780 MPa steel (DP780GA), transformation induced plasticity 780 MPa steel (TRIP780), and hot-stamped boron steel (HSBS). A low-cost Si3N4 ceramic tool was developed and used for making welds in this study instead of polycrystalline cubic boron nitride (PCBN) material used in earlier studies. FSSW has the advantages of solid-state, low-temperature process, and the ability of joining dissimilar grade of steels and thicknesses. Two different tool shoulder geometries, concave with smooth surface and convex with spiral pattern, were used in the study. Welds were made by a 2-step displacement control process with weld time of 4, 6, and 10 seconds. Static tensile lap-shear strength achieved 16.4 kN for DP780GA-HSBS and 13.2kN for TRIP780-HSBS, above the spot weld strength requirements by AWS. Nugget pull-out was the failure mode of the joint. The joining mechanism was illustrated from the cross-section micrographs. Microhardness measurement showed hardening in the upper sheet steel (DP780GA or TRIP780) in the weld, but softening of HSBS in the heat-affect zone (HAZ). The study demonstrated the feasibility of making high-strength AHSS spot welds with low-cost tools.

Levelized Costs for Nuclear, Gas and Coal for Electricity, under the Mexican Scenario  

SciTech Connect

In the case of new nuclear power stations, it is necessary to pay special attention to the financial strategy that will be applied, time of construction, investment cost, and the discount and return rate. The levelized cost quantifies the unitary cost of the electricity (the kWh) generated during the lifetime of the nuclear power plant; and allows the immediate comparison with the cost of other alternative technologies. The present paper shows levelized cost for different nuclear technologies and it provides comparison among them as well as with gas and coal electricity plants. For the calculations we applied our own methodology to evaluate the levelized cost considering investment, fuel and operation and maintenance costs, making assumptions for the Mexican market, and taking into account the gas prices projections. The study also shows comparisons using different discount rates (5% and 10%), and some comparisons between our results and an OECD 1998 study. The results are i n good agreement and shows that nuclear option is cost competitive in Mexico on the basis of levelized costs.

A high resolution view of the jet termination shock in a hot spot of the nearby radio galaxy Pictor A: implications for X-ray models of radio galaxy hot spots  

E-Print Network (OSTI)

Images made with the VLBA have resolved the region in a nearby radio galaxy, Pictor A, where the relativistic jet that originates at the nucleus terminates in an interaction with the intergalactic medium, a so-called radio galaxy hot spot. This image provides the highest spatial resolution view of such an object to date (16 pc), more than three times better than previous VLBI observations of similar objects. The north-west Pictor A hot spot is resolved into a complex set of compact components, seen to coincide with the bright part of the hot spot imaged at arcsecond-scale resolution with the VLA. In addition to a comparison with VLA data, we compare our VLBA results with data from the HST and Chandra telescopes, as well as new Spitzer data. The presence of pc-scale components in the hot spot, identifying regions containing strong shocks in the fluid flow, leads us to explore the suggestion that they represent sites of synchrotron X-ray production, contributing to the integrated X-ray flux of the hot spot, along with X-rays from synchrotron self-Compton scattering. This scenario provides a natural explanation for the radio morphology of the hot spot and its integrated X-ray emission, leading to very different predictions for the higher energy X-ray spectrum compared to previous studies. From the sizes of the individual pc-scale components and their angular spread, we estimate that the jet width at the hot spot is in the range 70 - 700 pc, which is comparable to similar estimates in PKS 2153-69, 3C 205, and 4C 41.17. The lower limit in this range arises from the suggestion that the jet may dither in its direction as it passes through hot spot backflow material close to the jet termination point, creating a "dentist drill" effect on the inside of a cavity 700 pc in diameter.

Essays on price dynamics, discovery, and dynamic threshold effects among energy spot markets in North America  

E-Print Network (OSTI)

Given the role electricity and natural gas sectors play in the North American economy, an understanding of how markets for these commodities interact is important. This dissertation independently characterizes the price dynamics of major electricity and natural gas spot markets in North America by combining directed acyclic graphs with time series analyses. Furthermore, the dissertation explores a generalization of price difference bands associated with the law of one price. Interdependencies among 11 major electricity spot markets are examined in Chapter II using a vector autoregression model. Results suggest that the relationships between the markets vary by time. Western markets are separated from the eastern markets and the Electricity Reliability Council of Texas. At longer time horizons these separations disappear. Palo Verde is the important spot market in the west for price discovery. Southwest Power Pool is the dominant market in Eastern Interconnected System for price discovery. Interdependencies among eight major natural gas spot markets are investigated using a vector error correction model and the Greedy Equivalence Search Algorithm in Chapter III. Findings suggest that the eight price series are tied together through sixlong-run cointegration relationships, supporting the argument that the natural gas market has developed into a single integrated market in North America since deregulation. Results indicate that price discovery tends to occur in the excess consuming regions and move to the excess producing regions. Across North America, the U.S. Midwest region, represented by the Chicago spot market, is the most important for price discovery. The Ellisburg-Leidy Hub in Pennsylvania and Malin Hub in Oregon are important for eastern and western markets. In Chapter IV, a threshold vector error correction model is applied to the natural gas markets to examine nonlinearities in adjustments to the law of one price. Results show that there are nonlinear adjustments to the law of one price in seven pair-wise markets. Four alternative cases for the law of one price are presented as a theoretical background. A methodology is developed for finding a threshold cointegration model that accounts for seasonality in the threshold levels. Results indicate that dynamic threshold effects vary depending on geographical location and whether the markets are excess producing or excess consuming markets.

Stories of the Unheard: A Case Study of Five Mexican American Dropouts Labeled as Demonstrating Learning Disabilities  

E-Print Network (OSTI)

This qualitative study examined the dropout crises from the perspectives of Mexican American dropouts labeled as learner disabled who were receiving special education services. Such study is imperative as this group increases both in school and in special education classes. There were two research questions that guided the study: 1. What are the perceptions of Mexican American dropouts who participated in a special education program regarding their educational experiences? 2. What were the factors that influenced these students’ decisions to drop out of school? From the participant interviews, historical academic documents, and rich-descriptive information gathered from the students’ voices, three themes were revealed as the primary reason for dropping out of school: non-responsive school culture, lack of supportive environment, and social factors. It was evident in the data collected that the school culture was unfavorable toward their learning and in meeting successful graduation requirements. Under non-responsive school culture, the following subthemes emerged as underlining factors to their dropping out: (a) low expectations, (b) non-caring for the student, (c) ineffective curriculum content, and (d) social issues at school. School-related factors such as the lack of a supportive environment revealed the following subthemes: (a) symptoms of school failure, (b) negative learning environment, and (c) culturally non-responsive instruction. Other attributing factors for dropping out of school included family structures and peer pressure. While each of the participants had unique experiences, each attributed non-responsive school culture, lack of supportive environment, and social context as major factors for dropping out of school. Therefore, the significance of this study lies in the potential to impact Mexican American student achievement in the reduction of dropouts.

Numerical studies of third-harmonic generation in laser filament in air perturbed by plasma spot  

Science Conference Proceedings (OSTI)

Third-harmonic emission from laser filament intercepted by plasma spot is studied by numerical simulations. Significant enhancement of the third-harmonic generation is obtained due to the disturbance of the additional plasma. The contribution of the pure plasma effect and the possible plasma-enhanced third-order susceptibility on the third-harmonic generation enhancement are compared. It is shown that the plasma induced cancellation of destructive interference [Y. Liu et al., Opt. Commun. 284, 4706 (2011)] of two-colored filament is the dominant mechanism of the enhancement of third-harmonic generation.

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

Science Conference Proceedings (OSTI)

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

Grain-Scale Simulations of Hot-Spot Initiation for Shocked TATB  

DOE Green Energy (OSTI)

High-explosive (HE) material consists of large-sized grains with micron-sized embedded impurities and pores. Under various mechanical/thermal insults, these pores collapse generating high-temperature regions leading to ignition. A computational study has been performed to investigate the mechanisms of pore collapse and hot spot initiation in TATB crystals, employing the thermohydrodynamics arbitrary-Lagrange-Eulerian code ALE3D. This initial study includes non-reactive dynamics to isolate the thermal and hydrodynamical effects. Two-dimensional high-resolution large-scale meso-scale simulations have been undertaken. We study an axisymmetric configuration for pore radii ranging from 0.5 to 2{micro}m, with initial shock pressures in the range from 3 to 11 GPa. A Mie-Gruneisen Equation of State (EOS) model is used for TATB, and includes a constant yield strength and shear modulus; while the air in the pore invokes a Livermore Equation of State (LEOS) model. The parameter space is systematically studied by considering various shock strengths, pore diameters and material properties. We find that thermal diffusion from the collapsed pores has an important effect in generating high-temperature hot spots in the TATB.

Wear testing of friction stir spot welding tools for joining of DP 980 Steel  

Science Conference Proceedings (OSTI)

Friction stir spot welding has been shown to be a viable method of joining ultra high strength steel (UHSS), both in terms of joint strength and process cycle time. However, the cost of tooling must be reasonable in order for this method to be adopted as an industrial process. Several tooling materials have been evaluated in prior studies, including silicon nitride and polycrystalline cubic boron nitride (PCBN). Recently a new tool alloy has been developed, where a blend of PCBN and tungsten rhenium (W-Re) was used in order to improve the toughness of the tool. Wear testing results are presented for two of these alloys: one with a composition of 60% PCBN and 40% W-Re (designated as Q60), and one with 70% PCBN and 30% W-Re (designated at Q70). The sheet material used for all wear testing was DP 980. Tool profiles were measured periodically during the testing process in order to show the progression of wear as a function of the number of spots produced. Lap shear testing was done each time a tool profile was taken in order to show the relationship between tool wear and joint strength. For the welding parameters chosen for this study the Q70 tool provided the best combination of wear resistance and joint strength.

Gas reservoir sweet spot detection and delineation in Rocky Mountain laramide basins. Topical report, May 1993-March 1996  

SciTech Connect

The determination of the position and configuration of the pressure boundary between normal and anomalously pressured regimes, and the detection and delineation of porosity/permeability `sweet spots` below this boundary are the two most important elements in exploring for basin-center or deep-basin gas in Rocky Mountain Laramide Basins. These two exploration elements from the basis for a new exploration paradigm. To utilize this new paradigm, the following tasks need to be included in the exploration strategy: (1) determine the position of the pressure boundary; (2) evaluate the three-dimensional aspects of the pressure boundary surface; (3) determine which depositional facies has the greatest potential for enhances storage capacity and deliverability below the pressure boundary; (4) document the determinative factors that control sweet spot development in the targeted lithofacies; and (5) detect and delineate sweet spots using 2-D and 3-D models of eletric log responses and seismic data.

Reciprocal space mapping by spot profile analyzing low energy electron diffraction  

SciTech Connect

We present an experimental approach for the recording of two-dimensional reciprocal space maps using spot profile analyzing low energy electron diffraction (SPA-LEED). A specialized alignment procedure eliminates the shifting of LEED patterns on the screen which is commonly observed upon variation of the electron energy. After the alignment, a set of one-dimensional sections through the diffraction pattern is recorded at different energies. A freely available software tool is used to assemble the sections into a reciprocal space map. The necessary modifications of the Burr-Brown computer interface of the two Leybold and Omicron type SPA-LEED instruments are discussed and step-by-step instructions are given to adapt the SPA 4.1d software to the changed hardware. Au induced faceting of 4 deg. vicinal Si(001) is used as an example to demonstrate the technique.

Analytic criteria for shock ignition of fusion reactions in a central hot spot  

Science Conference Proceedings (OSTI)

Shock ignition is an inertial confinement fusion scheme where the ignition conditions are achieved in two steps. First, the DT shell is compressed at a low implosion velocity creating a central core at a low temperature and a high density. Then, a strong spherical converging shock is launched before the fuel stagnation time. It increases the central pressure and ignites the core. It is shown in this paper that this latter phase can be described analytically by using a self-similar solution to the equations of ideal hydrodynamics. A high and uniformly distributed pressure in the hot spot can be created thus providing favorable conditions for ignition. Analytic ignition criteria are obtained that relate the areal density of the compressed core with the shock velocity. The conclusions of the analytical model are confirmed in full hydrodynamic simulations.

Recently a new tool alloy has been developed, using a blend of PCBN and tungsten rhenium (W-Re) in order to improve the toughness of the tool. Wear testing results are presented for two of these alloys: one with a composition of 60% PCBN and 40% W-Re, and one with 70% PCBN and 30% W-Re. The sheet material used for all wear testing was 1.4 mm DP 980. Lap shear testing was used to show the relationship between tool wear and joint strength. The Q70 tool provided the best combination of wear resistance and joint strength.

Empirical Analysis of the Spot Market Implications ofPrice-Responsive Demand  

SciTech Connect

Regardless of the form of restructuring, deregulatedelectricity industries share one common feature: the absence of anysignificant, rapid demand-side response to the wholesale (or, spotmarket) price. For a variety of reasons, most electricity consumers stillpay an average cost based regulated retail tariff held over from the eraof vertical integration, even as the retailers themselves are oftenforced to purchase electricity at volatile wholesale prices set in openmarkets. This results in considerable price risk for retailers, who aresometimes additionally forbidden by regulators from signing hedgingcontracts. More importantly, because end-users do not perceive real-time(or even hourly or daily) fluctuations in the wholesale price ofelectricity, they have no incentive to adjust their consumptionaccordingly. Consequently, demand for electricity is highly inelastic,which together with the non storability of electricity that requiresmarket clearing over very short time steps spawn many other problemsassociated with electricity markets, such as exercise of market power andprice volatility. Indeed, electricity generation resources can bestretched to the point where system adequacy is threatened. Economictheory suggests that even modest price responsiveness can relieve thestress on generation resources and decrease spot prices. To quantify thiseffect, actual generator bid data from the New York control area is usedto construct supply stacks and intersect them with demand curves ofvarious slopes to approximate the effect of different levels of demandresponse. The potential impact of real-time pricing (RTP) on theequilibrium spot price and quantity is then estimated. These resultsindicate the immediate benefits that could be derived from a moreprice-responsive demand providing policymakers with a measure of howprices can be potentially reduced and consumption maintained within thecapability of generation assets.

Empirical analysis of the spot market implications ofprice-elastic demand  

SciTech Connect

Regardless of the form of restructuring, deregulated electricity industries share one common feature: the absence of any significant, rapid demand-side response to the wholesale (or, spotmarket) price. For a variety of reasons, electricity industries continue to charge most consumers an average cost based on regulated retail tariff from the era of vertical integration, even as the retailers themselves are forced to purchase electricity at volatile wholesale prices set in open markets. This results in considerable price risk for retailers, who are sometimes forbidden by regulators from signing hedging contracts. More importantly, because end-users do not perceive real-time (or even hourly or daily) fluctuations in the wholesale price of electricity, they have no incentive to adjust their consumption in response to price signals. Consequently, demand for electricity is highly inelastic, and electricity generation resources can be stretched to the point where system stability is threatened. This, then, facilitates many other problems associated with electricity markets, such as market power and price volatility. Indeed, economic theory suggests that even modestly price-responsive demand can remove the stress on generation resources and decrease spot prices. To test this theory, we use actual generator bid data from the New York control area to construct supply stacks, and intersect them with demand curves of various slopes to approximate different levels of demand elasticity. We then estimate the potential impact of real-time pricing on the equilibrium spot price and quantity. These results indicate the immediate benefits that could be derived from a more price-elastic demand. Such analysis can provide policymakers with a measure of how effective price-elastic demand can potentially reduce prices and maintain consumption within the capability of generation resources.

Assessment of the Mexican Eagle Ford Shale Oil and Gas Resources  

E-Print Network (OSTI)

According to the 2011 Energy Information Agency (EIA) global assessment, Mexico ranks 4th in shale gas resources. The Eagle Ford shale is the formation with the greatest expectation in Mexico given the success it has had in the US and its liquids-rich zone. Accurate estimation of the resource size and future production, as well as the uncertainties associated with them, is critical for the decision-making process of developing shale oil and gas resources. The complexity of the shale reservoirs and high variability in its properties generate large uncertainties in the long-term production and recovery factors of these plays. Another source of uncertainty is the limited production history. Given all these uncertainties, a probabilistic decline-curve analysis approach was chosen for this study, given that it is relatively simple, it enables performing a play-wide assessment with available production data and, more importantly, it quantifies the uncertainty in the resource size. Analog areas in the US Eagle Ford shale were defined based on available geologic information in both the US and Mexico. The Duong model coupled with a Markov Chain Monte Carlo (MCMC) methodology was used to analyze and forecast production of wells located in the previously defined analog sectors in the US Eagle Ford shale. By combining the results of individual-well analyses, a type curve and estimated ultimate recovery (EUR) distribution for each of the defined analog sectors was obtained. These distributions were combined with well-spacing assumptions and sector areas to generate the prospective-resources estimates. Similar probabilistic decline-curve-analysis methodology was used to estimate the reserves and contingent resources of existing wells. As of March 2013, the total prospective resources (P90-P50-P10) for the Eagle Ford shale in Mexico (MX-EFS) are estimated to be 527-1,139-7,268 MMSTB of oil and 17- 37-217 TSCF of gas. To my knowledge, this is the first oil estimate published for this formation in Mexico. The most attractive sectors based on total estimated resources as well as individual-well type curves are located in the southeast of the Burgos Basin and east-west of the Sabinas basin. Because there has been very little development to date, estimates for reserves and contingent resources are much lower than those for prospective resources. Estimated reserves associated with existing wells and corresponding offset well locations are 18,375-34,722-59,667 MMSCF for gas and zero for oil. Estimated contingent resources are 14-64-228 MSTB of oil and 8,526-13,327- 25,983MMSCF of gas. The results of this work should provide a more reliable assessment of the size and uncertainties of the resources in the Mexican Eagle Ford shale than previous estimates obtained with less objective methodologies.

Radiological audit of remedial action activities at the processing sites Mexican Hat, Utah and Monument Valley, Arizona. Audit date: May 3--7, 1993, Final report  

SciTech Connect

The Uranium Mill Tailings Remedial Action (UMTRA) Project`s Technical Assistance Contractor (TAC) performed a radiological audit of the Remedial Action Contractor (RAC), MK-Ferguson and CWM Federal Environmental Services, Inc., at the processing sites in Mexican Hat, Utah, and Monument Valley, Arizona. This audit was conducted May 3--7, 1993, by Bill James and Gerry Simiele of the TAC. Three site-specific findings and four observations were identified during the audit and are presented in this report. The overall conclusion from the audit is that the majority of the radiological aspects of the Mexican Hat, Utah, and Monument Valley, Arizona, remedial action programs are performed adequately. However, the findings identify that there is some inconsistency in following procedures and meeting requirements for contamination control, and a lack of communication between the RAC and the DOE on variances from the published remedial action plan (RAP).

HOT AND COLD SPOT COUNTS AS PROBES OF NON-GAUSSIANITY IN THE COSMIC MICROWAVE BACKGROUND  

SciTech Connect

We introduce the numbers of hot and cold spots, n{sub h} and n{sub c} , of excursion sets of the cosmic microwave background (CMB) temperature anisotropy maps as statistical observables that can discriminate different non-Gaussian models. We numerically compute them from simulations of non-Gaussian CMB temperature fluctuation maps. The first kind of non-Gaussian model we study is the local type primordial non-Gaussianity. The second kind of model has some specific form of the probability distribution function from which the temperature fluctuation value at each pixel is drawn, obtained using HEALPIX. We find the characteristic non-Gaussian deviation shapes of n{sub h} and n{sub c} , which is distinct for each of the models under consideration. We further demonstrate that n{sub h} and n{sub c} carry additional information compared to the genus, which is just their linear combination, making them valuable additions to the Minkowski Functionals in constraining non-Gaussianity.

Do desperate times call for desperate measures? Strategic responses to regulatory punctuations in the Mexican banking industry, 1991-2004  

E-Print Network (OSTI)

Drawing insights from liability of foreignness, the punctuated equilibrium model and the resource-based view, this dissertation develops an integrated model to identify the successful strategies and characteristics of both domestic and foreign firms operating in emerging markets, affected by regulatory punctuations. Accordingly, three research questions are addressed: Why are some foreign firms more likely to survive than other foreign firms? Why are some domestic firms more likely to survive than other domestic firms? Are there any similarities between successful foreign firms and successful domestic firms? Using event-history methodologies and the Mexican banking industry as the unit of analysis, this dissertation shows the following results: Foreign firms (banks) from countries with stronger commercial ties to Mexico (the focal emerging market), were less likely to exit the banking industry. Also, the likelihood of exiting the industry, by a foreign firm, was negatively related to domestic firm (bank) acquisitions. For the domestic firms (banks), there was a positive relationship between international diversification and firm survival and a negative relationship between aggressive (loan) growth and firm survival. Also, marginal support was found about the positive relationship between “grupo” affiliation and firm survival. This research contributes to the extant literature by extending current theories when considering the effect of radical change. For instance, while punctuated equilibrium provides a good “environmental” explanation about a firm’s need to adapt to radical change, it does not suggest how firms should adapt to this change. However, by providing an explanation on how firms suppose to adapt to this radical change, this dissertation had expanded the theoretical implication of the punctuated equilibrium model. Similarly, the present dissertation provides a theoretical extension to liability of foreignness by finding that not all foreign firms face the same liability of foreignness. Lastly, the resource-based view is also extended by this dissertation research, as it is found to have implications for emerging markets firms that are different from foreign developed market firms.

Oxygen chemisorption on Cu(19 19 1) studied by spot profile analysis low-energy electron diffraction  

SciTech Connect

Cu(110) and the vicinal Cu(19 19 1) surfaces were characterized by recording maps of the reciprocal space by means of spot profile analysis low-energy electron diffraction (SPA-LEED). For both surfaces, kinematic simulations were performed to get insight into the main features of the experimental data. Furthermore, it is shown that chemisorption of oxygen and subsequent annealing lead to the formation of a Cu-CuO stripe phase and induce faceting of the Cu(19 19 1) surface. The evolution from the clean Cu(19 19 1) surface to the coexistence of the (110) and (111) facets with increasing oxygen exposure was characterized by SPA-LEED.

Magnetostatic focal spot correction for x-ray tubes operating in strong magnetic fields using iterative optimization  

Science Conference Proceedings (OSTI)

Purpose: Combining x-ray fluoroscopy and MR imaging systems for guidance of interventional procedures has become more commonplace. By designing an x-ray tube that is immune to the magnetic fields outside of the MR bore, the two systems can be placed in close proximity to each other. A major obstacle to robust x-ray tube design is correcting for the effects of the magnetic fields on the x-ray tube focal spot. A potential solution is to design active shielding that locally cancels the magnetic fields near the focal spot. Methods: An iterative optimization algorithm is implemented to design resistive active shielding coils that will be placed outside the x-ray tube insert. The optimization procedure attempts to minimize the power consumption of the shielding coils while satisfying magnetic field homogeneity constraints. The algorithm is composed of a linear programming step and a nonlinear programming step that are interleaved with each other. The coil results are verified using a finite element space charge simulation of the electron beam inside the x-ray tube. To alleviate heating concerns an optimized coil solution is derived that includes a neodymium permanent magnet. Any demagnetization of the permanent magnet is calculated prior to solving for the optimized coils. The temperature dynamics of the coil solutions are calculated using a lumped parameter model, which is used to estimate operation times of the coils before temperature failure. Results: For a magnetic field strength of 88 mT, the algorithm solves for coils that consume 588 A/cm{sup 2}. This specific coil geometry can operate for 15 min continuously before reaching temperature failure. By including a neodymium magnet in the design the current density drops to 337 A/cm{sup 2}, which increases the operation time to 59 min. Space charge simulations verify that the coil designs are effective, but for oblique x-ray tube geometries there is still distortion of the focal spot shape along with deflections of approximately 3 mm in the radial and circumferential directions on the anode. Conclusions: Active shielding is an attractive solution for correcting the effects of magnetic fields on the x-ray focal spot. If extremely long fluoroscopic exposure times are required, longer operation times can be achieved by including a permanent magnet with the active shielding design.

Using a Reduced Spot Size for Intensity-Modulated Proton Therapy Potentially Improves Salivary Gland-Sparing in Oropharyngeal Cancer  

Science Conference Proceedings (OSTI)

Purpose: To investigate whether intensity-modulated proton therapy with a reduced spot size (rsIMPT) could further reduce the parotid and submandibular gland dose compared with previously calculated IMPT plans with a larger spot size. In addition, it was investigated whether the obtained dose reductions would theoretically translate into a reduction of normal tissue complication probabilities (NTCPs). Methods: Ten patients with N0 oropharyngeal cancer were included in a comparative treatment planning study. Both IMPT plans delivered simultaneously 70 Gy to the boost planning target volume (PTV) and 54 Gy to the elective nodal PTV. IMPT and rsIMPT used identical three-field beam arrangements. In the IMPT plans, the parotid and submandibular salivary glands were spared as much as possible. rsIMPT plans used identical dose-volume objectives for the parotid glands as those used by the IMPT plans, whereas the objectives for the submandibular glands were tightened further. NTCPs were calculated for salivary dysfunction and xerostomia. Results: Target coverage was similar for both IMPT techniques, whereas rsIMPT clearly improved target conformity. The mean doses in the parotid glands and submandibular glands were significantly lower for three-field rsIMPT (14.7 Gy and 46.9 Gy, respectively) than for three-field IMPT (16.8 Gy and 54.6 Gy, respectively). Hence, rsIMPT significantly reduced the NTCP of patient-rated xerostomia and parotid and contralateral submandibular salivary flow dysfunction (27%, 17%, and 43% respectively) compared with IMPT (39%, 20%, and 79%, respectively). In addition, mean dose values in the sublingual glands, the soft palate and oral cavity were also decreased. Obtained dose and NTCP reductions varied per patient. Conclusions: rsIMPT improved sparing of the salivary glands and reduced NTCP for xerostomia and parotid and submandibular salivary dysfunction, while maintaining similar target coverage results. It is expected that rsIMPT improves quality of life during and after radiotherapy treatment.

A simulation study to verify Stone's simultaneous water and gas injection performance in a 5-spot pattern  

E-Print Network (OSTI)

Water alternating gas (WAG) injection is a proven technique to enhance oil recovery. It has been successfully implemented in the field since 1957 with recovery increase in the range of 5-10% of oil-initially-in-place (OIIP). In 2004, Herbert L. Stone presented a simultaneous water and gas injection technique. Gas is injected near the bottom of the reservoir and water is injected directly on top at high rates to prevent upward channeling of the gas. Stone's mathematical model indicated the new technique can increase vertical sweep efficiency by 3-4 folds over WAG. In this study, a commercial reservoir simulator was used to predict the performance of Stone's technique and compare it to WAG and other EOR injection strategies. Two sets of relative permeability data were considered. Multiple combinations of total injection rates (water plus gas) and water/gas ratios as well as injection schedules were investigated to find the optimum design parameters for an 80 acre 5-spot pattern unit. Results show that injecting water above gas may result in better oil recovery than WAG injection though not as indicated by Stone. Increase in oil recovery with SSWAG injection is a function of the gas critical saturation. The more gas is trapped in the formation, the higher oil recovery is obtained. This is probably due to the fact that areal sweep efficiency is a more dominant factor in a 5-spot pattern. Periodic shut-off of the water injector has little effect on oil recovery. Water/gas injection ratio optimization may result in a slight increase in oil recovery. SSWAG injection results in a steady injection pressure and less fluctuation in gas production rate compared to WAG injection.

Hoechst plans Mexican unit  

SciTech Connect

Hoechst is considering plans to build its first ethoxylates project in Mexico, Mark Sijthoff, head of surfactants and auxiliaries for Hoechst`s specialty chemical business unit, tells CW. The company expects to make a decision on the 30,000-m.t./year project by the end of the year. Sijthoff would not disclose the site or where ethylene oxide (EO) feed would be obtained. The plan may depend on results of the privatization of Petroleos Mexicanos (Pemex), which is the only producer of EO in Mexico. Hoechst is part of a consortium bidding on the privatization. Sources say the unit will be built at Quimica Hoechst`s Coatzacoalcos site, close to Pemex`s EO plants at Cangregera and Morelos. A planned EO expansion at Morelos will probably move ahead when the sell-off is completed. Sijthoff says that Hoechst is also looking at improving its US surfactants position, although the company has no plans to expand ethoxylates, as there is {open_quotes}plenty of capacity.{close_quotes} Hoechst started up a 150-million lbs/year plant at Clear Lake, TX last year, ending a tolling agreement with Union Carbide. In addition, Rhone-Poulenc recently started a unit at Marcus Hook, PA, and Condea Vista is doubling its ethoxylation capacity at Lake Charles, LA. Meanwhile, Hoechst is still considering construction of 30,000-m.t./year ethoxylation plant in India or China. A decision is expected later this year.

Expansion of the cathode spot and generation of shock waves in the plasma of a volume discharge in atmospheric-pressure helium  

SciTech Connect

The expansion of the cathode spot and the generation of shock waves during the formation and development of a pulsed volume discharge in atmospheric-pressure helium were studied by analyzing the emission spectra of the cathode plasma and the spatiotemporal behavior of the plasma glow. The transition of a diffuse volume discharge in a centimeter-long gap into a high-current diffuse mode when the gas pressure increased from 1 to 5 atm and the applied voltage rose from the statistical breakdown voltage to a 100% overvoltage was investigated. Analytical expressions for the radius of the cathode spot and its expansion velocity obtained in the framework of a spherically symmetric model agree satisfactorily with the experimental data.

Building A Simulation Model For The Prediction Of Temperature Distribution In Pulsed Laser Spot Welding Of Dissimilar Low Carbon Steel 1020 To Aluminum Alloy 6061  

Science Conference Proceedings (OSTI)

This paper describes the development of a computer model used to analyze the heat flow during pulsed Nd: YAG laser spot welding of dissimilar metal; low carbon steel (1020) to aluminum alloy (6061). The model is built using ANSYS FLUENT 3.6 software where almost all the environments simulated to be similar to the experimental environments. A simulation analysis was implemented based on conduction heat transfer out of the key hole where no melting occurs. The effect of laser power and pulse duration was studied.Three peak powers 1, 1.66 and 2.5 kW were varied during pulsed laser spot welding (keeping the energy constant), also the effect of two pulse durations 4 and 8 ms (with constant peak power), on the transient temperature distribution and weld pool dimension were predicated using the present simulation. It was found that the present simulation model can give an indication for choosing the suitable laser parameters (i.e. pulse durations, peak power and interaction time required) during pulsed laser spot welding of dissimilar metals.

Spot Scanning-Based Proton Therapy for Intracranial Meningioma: Long-Term Results From the Paul Scherrer Institute  

SciTech Connect

Background: To assess the long-term clinical results of spot scanning proton therapy (PT) in the treatment of intracranial meningiomas. Patients and Methods: Thirty-nine patients with meningioma (histologically proven 34/39) were treated with PT between July 1997 and January 2010. Thirty-two (82.1%) patients were treated as primary treatment (exclusive PT, n = 8; postoperative PT, n = 24). Mean age was 48.3 {+-} 17.9 years and 32 (82.1%) patients had skull base lesions. For patients undergoing surgery, 24 patients had a diagnosis of World Health Organization (WHO) Grade I and 10 of a WHO Grade II/III meningioma, respectively. The female-to-male ratio was 3.3. The median administered dose was 56.0 Gy (relative biologic effectiveness [RBE]) (range, 52.2-66.6) at 1.8-2.0 Gy (RBE) per fraction. Gross tumor volume (GTV) ranged from 0.76 to 546.5 cm{sup 3} (median, 21.5). Late toxicity was assessed according to Common Terminology Criteria for Adverse Events version 3.0. Mean follow-up time was 62.0 months and all patients were followed for >6 months. Results: Six patients presented with tumor recurrence and 6 patients died during follow-up, of which 4 of tumor progression. Five-year actuarial local control and overall survival rates were 84.8% and 81.8%, respectively, for the entire cohort and 100% for benign histology. Cumulative 5-year Grade {>=}3 late toxicity-free survival was 84.5%. On univariate analysis, LC was negatively influenced by WHO grade (p = 0.001), GTV (p = 0.013), and male gender (p = 0.058).

Multi-Scale Multi-physics Methods Development for the Calculation of Hot-Spots in the NGNP  

Science Conference Proceedings (OSTI)

Radioactive gaseous fission products are released out of the fuel element at a significantly higher rate when the fuel temperature exceeds 1600°C in high-temperature gas-cooled reactors (HTGRs). Therefore, it is of paramount importance to accurately predict the peak fuel temperature during all operational and design-basis accident conditions. The current methods used to predict the peak fuel temperature in HTGRs, such as the Next-Generation Nuclear Plant (NGNP), estimate the average fuel temperature in a computational mesh modeling hundreds of fuel pebbles or a fuel assembly in a pebble-bed reactor (PBR) or prismatic block type reactor (PMR), respectively. Experiments conducted in operating HTGRs indicate considerable uncertainty in the current methods and correlations used to predict actual temperatures. The objective of this project is to improve the accuracy in the prediction of local "hot" spots by developing multi-scale, multi- physics methods and implementing them within the framework of established codes used for NGNP analysis. The multi-scale approach which this project will implement begins with defining suitable scales for a physical and mathematical model and then deriving and applying the appropriate boundary conditions between scales. The macro scale is the greatest length that describes the entire reactor, whereas the meso scale models only a fuel block in a prismatic reactor and ten to hundreds of pebbles in a pebble bed reactor. The smallest scale is the micro scale--the level of a fuel kernel of the pebble in a PBR and fuel compact in a PMR--which needs to be resolved in order to calculate the peak temperature in a fuel kernel.

Is there a single spot size and grid for intensity modulated proton therapy? Simulation of head and neck, prostate and mesothelioma cases  

Science Conference Proceedings (OSTI)

Purpose: To assess the quality of dose distributions in real clinical cases for different dimensions of scanned proton pencil beams. The distance between spots (i.e., the grid of delivery) is optimized for each dimension of the pencil beam. Methods: The authors vary the {sigma} of the initial Gaussian size of the spot, from {sigma}{sub x} = {sigma}{sub y} = 3 mm to {sigma}{sub x} = {sigma}{sub y} = 8 mm, to evaluate the impact of the proton beam size on the quality of intensity modulated proton therapy (IMPT) plans. The distance between spots, {Delta}x and {Delta}y, is optimized on the spot plane, ranging from 4 to 12 mm (i.e., each spot size is coupled with the best spot grid resolution). In our Hyperion treatment planning system (TPS), constrained optimization is applied with respect to the organs at risk (OARs), i.e., the optimization tries to satisfy the dose objectives in the planning target volume (PTV) as long as all planning objectives for the OARs are met. Three-field plans for a nasopharynx case, two-field plans for a prostate case, and two-field plans for a malignant pleural mesothelioma case are considered in our analysis. Results: For the head and neck tumor, the best grids (i.e., distance between spots) are 5, 4, 6, 6, and 8 mm for {sigma} = 3, 4, 5, 6, and 8 mm, respectively. {sigma} {low dose and {sigma}{dose. For the prostate patient, the best grid is 4, 4, 5, 5, and 5 mm for {sigma} = 3, 4, 5, 6, and 8 mm, respectively. Beams with {sigma} > 3 mm did not satisfy our first clinical requirement that 95% of the prescribed dose is delivered to more than 95% of prostate and proximal seminal vesicles PTV. Our second clinical requirement, to cover the distal seminal vesicles PTV, is satisfied for beams as wide as {sigma} = 6 mm. For the mesothelioma case, the low dose PTV prescription is well respected for all values of {sigma}, while there is loss of high dose PTV coverage for {sigma} > 5 mm. The best grids have a spacing of 6, 7, 8, 9, and 12 mm for {sigma} = 3, 4, 5, 6, and 8 mm, respectively. Conclusions: The maximum acceptable proton pencil beam {sigma} depends on the volume treated, the protocol of delivery, and optimization of the plan. For the clinical cases, protocol and optimization used in this analysis, acceptable {sigma}s are {<=} 4 mm for the head and neck tumor, {<=} 3 mm for the prostate tumor and {<=} 6 mm for the malignant pleural mesothelioma. One can apply the same procedure used in this analysis when given a ''class'' of patients, a {sigma} and a clinical protocol to determine the optimal grid spacing.

The effect of urinary cadmium on cardiovascular fitness as measured by VO{sub 2} max in white, black and Mexican Americans  

SciTech Connect

Objectives: We explored potential effects of cadmium exposure on cardiovascular fitness measures, including gender and racial/ethnic differences. Methods: Data were from the 1999 to 2000 National Health and Nutrition Examination Survey (NHANES); 1963 participating subjects were included in our analysis. Volume of oxygen consumed at sub-maximum activity (VO{sub 2} max) were recorded in a series of graded exercises; the goal was to elicit 75% of predetermined age-specific heart rates. Cadmium from urine samples was measured in the laboratory using standard methods. Multivariate linear regression analyses were performed to determine potential relationships. Results: Increased urinary cadmium concentrations were generally associated with decreased estimated VO{sub 2} max values. Gender and racial/ethnic differences were also observed. Specifically, associations were statistically significant for white males and Mexican American females. Conclusion: Inverse associations between urinary cadmium concentrations and estimated VO{sub 2} max values were observed, including racial and gender differences. The implications of such gender and racial/ethnic differences on long-term cardiovascular health and health disparities of present public health concern warrant further investigation.

Chorazy M. Seasonal variations in levels of DNA adducts and X-spots in human populations living in different parts of Poland. Environ Health Perspect  

E-Print Network (OSTI)

White blood cell DNA adducts were measured in coke oven workers, in residents from the area next to the coke oven in Silesia, Poland (highly industrialized region), and in residents from the rural area of Poland using the 32P-postlabeling technique. This method detected aromatic adducts including adducts formed by polycyclic aromatic hydrocarbons (PAHs). Highest levels of adducts in DNA were seen in the group of coke battery workers (6.9 adducts/10 ' nucleotides). Seasonal variations in levels of DNA adducts were observed both in residents of the district near the coke oven area and individuals from the rural area of Poland. Blood samples collected from people living near the coke oven in winter showed much higher levels of DNA adducts than blood samples obtained in summer (5.0 adducts/lO ' nucleotides in winter and 1A adducts/10' nucleotides in summer). The difference in the level ofDNA adducts between winter and summer was smaller in the group of people living in the rural area (3.2 adducts/10 and 2.2 adducts/10, respectively). In most cases the levels of X-spots correlated with the levels of other DNA adducts. Correlation coefficients(r) between the levels of X-spots and other adducts ranged between 0A6 and 0.74 (poven workers where no correlation was observed.

A comparison of automated land cover/use classification methods for a Texas bottomland hardwood system using lidar, spot-5, and ancillary data  

E-Print Network (OSTI)

Bottomland hardwood forests are highly productive ecosystems which perform many important ecological services. Unfortunately, many bottomland hardwood forests have been degraded or lost. Accurate land cover mapping is crucial for management decisions affecting these disappearing systems. SPOT-5 imagery from 2005 was combined with Light Detection and Ranging (LiDAR) data from 2006 and several ancillary datasets to map a portion of the bottomland hardwood system found in the Sulphur River Basin of Northeast Texas. Pixel-based classification techniques, rulebased classification techniques, and object-based classification techniques were used to distinguish nine land cover types in the area. The rule-based classification (84.41% overall accuracy) outperformed the other classification methods because it more effectively incorporated the LiDAR and ancillary datasets when needed. This output was compared to previous classifications from 1974, 1984, 1991, and 1997 to determine abundance trends in the area’s bottomland hardwood forests. The classifications from 1974-1991 were conducted using identical class definitions and input imagery (Landsat MSS 60m), and the direct comparison demonstrates an overall declining trend in bottomland hardwood abundance. The trend levels off in 1997 when medium resolution imagery was first utilized (Landsat TM 30m) and the 2005 classification also shows an increase in bottomland hardwood from 1997 to 2005, when SPOT-5 10m imagery was used. However, when the classifications are re-sampled to the same resolution (60m), the percent area of bottomland hardwood consistently decreases from 1974-2005. Additional investigation of object-oriented classification proved useful. A major shortcoming of object-based classification is limited justification regarding the selection of segmentation parameters. Often, segmentation parameters are arbitrarily defined using general guidelines or are determined through a large number of parameter combinations. This research justifies the selection of segmentation parameters through a process that utilizes landscape metrics and statistical techniques to determine ideal segmentation parameters. The classification resulting from these parameters outperforms the classification resulting from arbitrary parameters by approximately three to six percent in terms of overall accuracy, demonstrating that landscape metrics can be successfully linked to segmentation parameters in order to create image objects that more closely resemble real-world objects and result in a more accurate final classification.

The monitoring during 2012 focused on documenting the status of known burrows. Newly identified burrows were documented while examining historical locations, during ecological resource reviews, or discovered during other monitoring efforts. The timing of the monitoring effort allowed staff to perform the surveys without disrupting any breeding or hatching, while also allowing for easy discernment of adults from juveniles, which helped in determining burrow-use type.

Mexican firms commit to responsabilidad integral  

SciTech Connect

With the prospect of Mexico joining the North American Free Trade Agreement (NAFTA), eyes are on the environmental performance of that country's chemical industry. Its image has already been dented directly by pollution problems at certain maquiladora plants on the U.S. border, and indirectly by the April explosions at Guadalajara, blamed on gasoline leaks from state oil group Petroleos Mexicanos, (Pemex). NAFTA has drown the issue into focus, since the pact could encourage companies to build plants in Mexico to take advantage of cheaper labor costs. Concerned that laxer environmental provisions could also play a part, environmentalists are pressuring Washington to ensure that NAFTA puts Mexico on a par with the rest of North America. But chemical markers assert that Mexico's environmental legislation is already similar to that of the US. And, under the administration of President Carlos Salinas Gortari, the Ministry of Social Development has upped enforcement, fined a number of producers, and closed down some chemical units for failing to meet environmental regulations.

Quantitative LEED I-V and ab initio study of the Si(111)-3x2-Sm surface structure and the missing half-order spots in the 3x1 diffraction pattern  

SciTech Connect

We have used low-energy electron diffraction (LEED) I-V analysis and ab initio calculations to quantitatively determine the honeycomb chain model structure for the Si(111)-3x2-Sm surface. This structure and a similar 3x1 recontruction have been observed for many alkali-earth and rare-earth metals on the Si(111) surface. Our ab initio calculations show that there are two almost degenerate sites for the Sm atom in the unit cell, and the LEED I-V analysis reveals that an admixture of the two in a ratio that slightly favors the site with the lower energy is the best match to experiment. We show that the I-V curves are insensitive to the presence of the Sm atom and that this results in a very low intensity for the half-order spots, which might explain the appearance of a 3x1 LEED pattern produced by all of the structures with a 3x2 unit cell.

Distillate and Spot Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: This slide shows the strong influence crude oil prices have on retail distillate prices. The price for distillate fuel oil tracks the crude price increases seen in 1996 and the subsequent fall in 1997 and 1998. Distillate prices have also followed crude oil prices up since the beginning of 1999. Actual data show heating oil prices on the East Coast in June at $1.20 per gallon, up 39 cents over last June. However, if heating oil prices are following diesel, they may be up another 5 cents in August. That would put heating oil prices about 40 cents over last August prices. Crude oil prices are only up about 25 cents in August over year ago levels. The extra 15 cents represents improved refiner margins due in part to the very low distillate inventory level.

New pemex agency, smog checks greet Mexican LPG vehicle users  

Science Conference Proceedings (OSTI)

This paper reports that the relaxation of prohibitions on the use of propane as a motor fuel has spurred sizeable business activity in carburetion and higher demand for LPG throughout Mexico and particularly in Mexico City. However, a number of unforeseen problems have developed that required tough, immediate solutions. After the alternative fuels project began at city hall in Mexico City, publicity spread nationwide, reportedly spurring conversion activity in many other cities. That led to additional demand for fuel of a magnitude that few people had anticipated. In order to assume control of the situation, the national oil company, Pemex, established an official LPG Motor Fuel Department on June 1. Operating in conjunction with the Ministry of Industry, the new department has been busy registering every major propane-powered fleet in the country. Most important, the rate of conversion work must now be pegged to the availability of fuel. It is believed that conversion activity has become more evenly paced since the new Pemex agency took over.over.

Free trade and freer petchems drive Mexican restructuring  

Science Conference Proceedings (OSTI)

When Mexico first opened up its protected markets in 1987 by cutting import tariffs, it thrust the chemical industry into a phase of change. Now, with the advent of the North American Free Trade Agreement(NAFTA) and the liberalization of petrochemicals by state oil group Petroleos Mexicanos (Pemex), restructuring has moved up a gear.

The Role of Viscosity in TATB Hot Spot Ignition  

SciTech Connect

The role of dissipative effects, such as viscosity, in the ignition of high explosive pores is investigated using a coupled chemical, thermal, and hydrodynamic model. Chemical reactions are tracked with the Cheetah thermochemical code coupled to the ALE3D hydrodynamic code. We perform molecular dynamics simulations to determine the viscosity of liquid TATB. We also analyze shock wave experiments to obtain an estimate for the shock viscosity of TATB. Using the lower bound liquid-like viscosities, we find that the pore collapse is hydrodynamic in nature. Using the upper bound viscosity from shock wave experiments, we find that the pore collapse is closest to the viscous limit.

IRIS Reactor a Suitable Option to Provide Energy and Water Desalination for the Mexican Northwest Region  

SciTech Connect

The Northwest region of Mexico has a deficit of potable water, along this necessity is the region growth, which requires of additional energy capacity. The IRIS reactor offers a very suitable source of energy given its modular size of 300 MWe and it can be coupled with a desalination plant to provide the potable water for human consumption, agriculture and industry. The present paper assess the water and energy requirements for the Northwest region of Mexico and how the deployment of the IRIS reactor can satisfy those necessities. The possible sites for deployment of Nuclear Reactors are considered given the seismic constraints and the closeness of the sea for external cooling. And in the other hand, the size of the desalination plant and the type of desalination process are assessed accordingly with the water deficit of the region.

Trade-concentration and its impact on commerce and traders of a Mexican city  

E-Print Network (OSTI)

This dissertation evaluates the changes in food retailing patterns in the face of openmarket trends in a medium sized city (Citlalicalli) in central Mexico. This evaluation is carried out using the model of retail trade-concentration. The following questions are addressed: whether trade-concentration had occurred in the field-site; if yes, what were the causes; and, what were the effects of retail concentration on preexisting food retailers. The fieldwork for this study was conducted over a 14 month period (May 2005 and June 2006). Empirical data were collected using three surveys, over 25 interviews, and several hours of participant observations. Along with these primary data, secondary data from official records were also collected. The survey data were analyzed using nonparametric tests. The findings from the study revealed that trade-concentration is proceeding in Citlalicalli and the recent spread of large stores in the region has been encouraged by free-trade policies adopted by Mexico since the mid-1980s. Trade-concentration in the Altepetl metropolitan area has also been aided by the positive behavior that consumers show towards large retail chains. Contrary to popular belief, the impact of retail concentration on preexisting small retailers in Citlalicalli has been minimal. Partly traditions and partly the nearness of a particular store explain the continued patronization of small stores by consumers. The product category and income of consumers also influence their purchase decisions. This research shows that competition in food retailing in developing countries is between same size and same type retailers. Small retailers are not always in direct competition with modern retailers as they serve different sections of the society. Retail development is a part of urban development and, therefore, has direct implications for the quality of life in cities. In emerging economies, cities like Citlalicalli have vibrant town centers which provide convenient access to offices, shops, and entertainment areas for its citizens. This study concludes that appropriate policy measures can ensure the coexistence of large and small retailers in developing countries and, thereby, the continued vitality of city centers.

A Summary of the Experience of Two Mexican Industrial Energy Centers  

E-Print Network (OSTI)

In 1995, the United States Department of Energy (DOE) began a program in Mexico to promote energy efficient products and services. Faculty and students at two universities were trained to perform assessments to identify energy-conserving opportunities at small and medium-sized manufacturers. Recommendations included improving combustion equipment, such as boilers; process equipment, such as motors and air compressors; and buildings and grounds, such as lighting or heating, ventilation, and air conditioning systems. On average, the cost savings recommended from the assessments were approximately 13% of the annual energy costs for the plants and manufacturers implemented approximately 50% of the recommended cost savings. Initial feedback indicates that there is a great potential for future assessments in the Mexico City and Monterrey areas.

INNOVATIVE METHODOLOGY FOR DETECTION OF FRACTURE-CONTROLLED SWEET SPOTS IN THE NORTHERN APPALACHIAN BASIN  

SciTech Connect

The primary goal was to enter Phase 2 by analyzing geophysical logs and sidewall cores from a verification well drilled into the Trenton/Black River section along lineaments. However, the well has not yet been drilled; Phase 2 has therefore not been accomplished. Secondary goals in Phase I were also completed for the last reporting period. Thus, no new data were collected for this reporting period, and only soil gas surveys were reanalyzed and re-displayed in the region of the Trenton/Black River wells. The soil gas profiles in the region of the Trenton/Black River wells show that individual large-magnitude soil gas anomalies (spikes) are rarely wider than 50 m. Even clusters of soil gas spikes are only on the order of 200-250 m wide. Thus, widely-spaced sampling will not necessarily represent the actual number and location of soil gas seeps. The narrowness of the anomalies suggests that the seeps result from single fractures or narrow fracture intensification domains (FIDs). Many of the lineaments from EarthSat (1997) and straight stream segments coincide (or are very close to) soil gas spikes, but we collected many more soil gas spikes than lineaments. Among some of the soil gas box surveys, a possible ENE-trend of spikes can be discerned. This ENE-striking trend is, however, about 10{sup o} away from a nearby Earthsat (1997) trend. These data continue to demonstrate that integration of aeromagnetic and remote sensing lineaments, surface structure, soil gas and seismic allows us to extrapolate Trenton-Black River trends away from confirmatory seismic lines.

Development of Appropriate Spot Welding Practice for Advanced High Strength Steels (TRP 0114)  

SciTech Connect

This program evaluated the effects of common manufacturing variables on spike-tempering effectiveness. The investigation used design-of-experiment (DOE) techniques, and examined both dual-phase and martensitic grades of high-strength steels (HSS). The specific grades chosen for this project were: Dual-phase (DP) 600, galvannealed (GA), 1.55 mm (DP) 600; Dual-phase (DP) 980 (uncoated), 1.55 mm (DP) 980; and Martensitic (M) 1300, 1.55 mm (M) 1300. Common manufacturing conditions of interest included tempering practice (quench and temper time), button size, simulated part fitup (sheet angular misalignment and fitup), and electrode wear (increased electrode face diameter). All of these conditions were evaluated against mechanical performance (static and dynamic tensile shear). Weld hardness data was also used to examine correlations between mechanical performance and the degree of tempering. Mechanical performance data was used to develop empirical models. The models were used to examine the robustness of weld strength and toughness to the selected processing conditions. This was done using standard EWI techniques. Graphical representations of robustness were then coupled with metallographic data to relate mechanical properties to the effectiveness of spike tempering. Mechanical properties for all three materials were relatively robust to variation in tempering. Major deviations in mechanical properties were caused by degradation of the weld itself. This was supported by a lack of correlation between hardness data and mechanical results. Small button sizes and large electrode face diameters (worn electrodes) produced large reductions in both static and dynamic strength levels when compared to standard production setups. Dynamic strength was further degraded by edge-located welds.

A 4-spot time-of-flight anemometer for small centrifugal compressor velocity measurements  

SciTech Connect

The application of laser anemometry techniques in turbomachinery facilities is a challenging dilemma requiring an anemometer system with special qualities. Here, we describe the use of a novel laser anemometry technique applied to a small 4.5 kg/s, 4:1 pressure ratio centrifugal compressor. Sample velocity profiles across the blade pitch are presented for a single location along the rotor. The results of the intra-blade passage velocity measurements will ultimately be used to verify CFD 3-D viscous code predictions.

Expanding beta-turn analogs for mimicking protein-protein hot spots  

E-Print Network (OSTI)

Solid-phase syntheses of two 14-membered ring peptidomimetics were done to determine whether or not a beta-turn structure can facilitate macrocyclization. NMR methods, together with CD and QMD calculations, do not fully support this assumption. However, cyclizations of more ordered structures like those of compounds 2 were more efficient than those for highly strained ring systems like 1. A small library of 18-membered ring peptidomimetics that accommodate an extra amino acid residue was synthesized on resin. Their syntheses were not complicated by head-to-tail dimer impurity, unlike those for previously synthesized 14-membered systems. These larger macrocycles exhibit beta-turn structures as verified by NMR, CD and QMD techniques. Moreover, two compounds in this series (3a and 3g) were shown to have agonistic properties for TrkC in cell survival assays. Dimerization of monovalent mimics was achieved first by modifying the organic template so that monovalent mimics with requisite functional groups can be synthesized. Second, the monovalent units were dimerized using sequential nucleophilic substitutions on fluorescently labeled dichlorotriazine. Our rationale to make bivalent compounds out of monovalent ones was justified when compound 4 was shown to bind TrkA with a 20 nM affinity. Reactions of amino acids with NH4SCN under acylating conditions produced 2-thiohydantoins in which the nitrogen of the amino acid (N1) was acylated. This was proven by 2-D NMR which showed no cross-peak between the NH signal observed and the C?±-H of the amino acid. When the compound was deacylated, a new NH signal appeared and the corresponding cross-peak with the C?±-H was observed. Solution-phase syntheses of non-peptidic mimics were achieved by doing a double substitution on a dihalogenated nitrobenzene scaffold. Sonogashira and SNAr reactions were done to install the required side-chains to give the desired compounds. These non-peptidic compounds can be easily adapted to our DTAF-Inp dimerization protocol since the nitro groups can be easily reduced. Attempts to make a spirotetracyclic peptidomimetic with three side chain mimics were done by synthesizing the spirocyclic diketopiperazine precursor. The synthesis of the DKP was achieved by making the cyclic quaternary amino acid that was coupled to another amino acid via the HOAt-EDC method. This protocol gave dipeptides in high yields. These dipeptides were deprotected and cyclized to the DKP under mildly acidic conditions in toluene.

INNOVATIVE METHODOLOGY FOR DETECTION OF FRACTURE-CONTROLLED SWEET SPOTS IN THE NORTHERN APPALACHIAN BASION  

Science Conference Proceedings (OSTI)

During this reporting period, Fortuna retrieved the first oriented horizontal core from the Trenton/Black River in the northern Appalachian Basin. The core came from central New York State, the ''hottest'' play in the Appalachian Basin. A complete well log suite was also collected in the horizontal hole, including an FMI log. After reassembling the core sections, and orienting the core, we analyzed the whole core before it was cut for full-diameter core analyses (e.g., permeability) and before the core was split, in order that we did not miss any features that may be lost during cutting. We recognized and mapped along the core 43 stylolites, 99 veins and several large partially filled vugs. Kinematic indicators suggest multiple phases of strike-slip motion. Master-abutting relationships at intersections (primarily determined from which feature ''cuts'' which other feature) show three stages of stylolite growth: sub horizontal, nearly vertical, and steeply dipping. These development stages reflect vertical loading, tectonic horizontal loading, and finally oblique loading. Hydrothermal dolomite veins cut and are cut by all three stages of the stylolites. A set of horizontal veins indicates vertical unloading. Analyses of the core will continue, as well as the well logs.

Hot spot detection system for vanes or blades of a combustion turbine  

DOE Patents (OSTI)

This invention includes a detection system that can determine if a turbine component, such as a turbine vane or blade, has exceeded a critical temperature, such as a melting point, along any point along the entire surface of the vane or blade. This system can be employed in a conventional combustion turbine having a compressor, a combustor and a turbine section. Included within this system is a chemical coating disposed along the entire interior surface of a vane or blade and a closed loop cooling system that circulates a coolant through the interior of the vane or blade. If the temperature of the vane or blade exceeds a critical temperature, the chemical coating will be expelled from the vane or blade into the coolant. Since while traversing the closed loop cooling system the coolant passes through a detector, the presence of the chemical coating in the coolant will be sensed by the system. If the chemical coating is detected, this indicates that the vane or blade has exceeded a critical temperature.

On the hot-spot-controlled critical heat flux mechanism in pool boiling of saturated fluids  

SciTech Connect

In this paper, we further investigate the hypothesis that the critical heat flux (CHF) occurs when some point on the heated surface reaches a high enough temperature that liquid can no longer contact that point, resulting in a gradual but continuous increase in the overall surface temperature. This hypothesis unifies the occurrence of the CHF and the quenching of hot surfaces by relating both to the same concept, i.e., the ability of a liquid to contact a hot surface. We use a two-dimensional transient conduction model to study the boiling phenomenon in the second transition region of saturated pool nucleate boiling on a horizontal surface. The heater surface is assumed to consist of two regions: a dry patch region formed as a result of complete evaporation of the thinner liquid macrolayers and a two-phase macrolayer region formed by numerous vapor stems penetrating relatively thick liquid macrolayers. The constitutive relations used to determine the stem-macrolayer configuration in the two-phase macrolayer region of the boiling surface were reevaluated for Gaertner's clean water and water-nickel/salt solution. 29 refs.

Included within this system is a chemical coating disposed along the entire interior surface of a vane or blade and a closed loop cooling system that circulates a coolant through the interior of the vane or blade. If the temperature of the vane or blade exceeds a critical temperature, the chemical coating will be expelled from the vane or blade into the coolant. Since while traversing the closed loop cooling system the coolant passes through a detector, the presence of the chemical coating in the coolant will be sensed by the system. If the chemical coating is detected, this indicates that the vane or blade has exceeded a critical temperature. 5 figs.

Raman Scattering from 1,3-Propanedithiol at a Hot Spot: Theory Meets Experiment  

SciTech Connect

We compute the Raman spectra of 1,3-propanedithiol (PDT) in the gas phase, in methanol, linked either to the face or vertex of a finite tetrahedral Ag20 cluster, and linking two Ag20 clusters using tools of density functional theory. The calculated normal mode-dependent molecular polarizability derivative tensors are employed to simulate single molecule surface-enhanced Raman (SERS) spectra. This is achieved by rotating the polarizability tensors of an individual molecule with respect to explicitly defined vector components of the incident and scattered radiation. Our results provide a basis for understanding commonly observed phenomena in single molecule SERS spectroscopy.

Complex Adaptive Systems (CAS) can be applied to investigate complex infrastructure interdependencies including those between the electric power and natural gas markets. The electric power and natural gas markets are undergoing fundamental transformations. These transformations include major changes in electric generator fuel sources. Electric generators that use natural gas as a fuel source are rapidly gaining market share. Electric generators using natural gas introduce direct interdependency between the electric power and natural gas markets. The interdependencies between the electric power and natural gas markets introduced by these generators can be investigated using the emergent behavior of CAS model agents.

In the structure task, the goals for this reporting period were to: (1) complete field work on the NNW-SSE transect along the west side of Cayuga Lake; (2) collect data at additional field sites in order to (a) trace structural trends between the two N-S transects and (b) fill in data gaps on the NS transect along the eastern shore of Seneca Lake; (3) enter the data gathered from the summer field work; (4) enter data from the previous field season that still had to be analyzed after a personnel change. We have completed data reduction for all the goals listed above, including the NNW-SSE transect on the west side of Cayuga Lake. In the soil gas task, the goals for this reporting period were to: (1) trace Trenton/Black River fault trends between the two N-S transects; and (2) enter the data gathered from the summer field work. We have completed data reduction for all the goals listed above, and have begun constructing maps that portray the data. These data continue to demonstrate that integration of aeromagnetic and Landsat lineaments, surface structure, soil gas and seismic allows us to extrapolate Trenton-Black River trends away from confirmatory seismic lines.

Probing the 3.6 Micron CIRB with Spitzer in 3 DIRBE Dark Spots  

E-Print Network (OSTI)

We observed three regions of the sky with Spitzer in which the Cosmic InfraRed Background (CIRB) has been determined at 3.5 microns using the method of subtracting 2MASS stellar fluxes from zodiacal light subtracted DIRBE maps. For each of these regions we have obtained 270 seconds of integration time per pixel with IRAC on Spitzer over the central square degree. We present galaxy counts in each of these approximately 1 square degree IRAC surveys. Along with deep galaxy counts in the Extended Groth Strip and GOODS North, we are able to compare the galactic contribution to the CIRB with the "DIRBE minus 2MASS'' determined L-band CIRB. Using the profile-fit photometry package GIM2D, we find a substantially larger flux contribution to the CIRB than that determined using aperture photometry. We have also made the first rigorous analysis of the uncertainties in determining the CIRB via galaxy counts in Spitzer images using a Monte Carlo Markov Chain simulation of our data analysis. Using a simple broken power law model for galaxy counts as a function of magnitude we find a most probable contribution to the CIRB from galaxies at 3.6 microns of 10.8^{+2.1}_{-1.1} kJy/sr. Even with this restricted model, however, we find that galaxy counting does not strongly constrain the CIRB from above. We are able to find solutions in which the CIRB runs away to large intensities without the need for an additional diffuse source.

www.mdpi.com/journal/ijerph Communication Mercury Levels in Locally Manufactured Mexican Skin-Lightening Creams  

E-Print Network (OSTI)

Abstract: Mercury is considered one of the most toxic elements for plants and animals. Nevertheless, in the Middle East, Asia and Latin America, whitening creams containing mercury are being manufactured and purchased, despite their obvious health risks. Due to the mass distribution of these products, this can be considered a global public health issue. In Mexico, these products are widely available in pharmacies, beauty aid and health stores. They are used for their skin lightening effects. The aim of this work was to analyze the mercury content in some cosmetic whitening creams using the cold vapor technique coupled with atomic absorption spectrometry (CV-AAS). A total of 16 skin-lightening creams from the local market were investigated. No warning information was noted on the packaging. In 10 of the samples, no mercury was detected. The mercury content in six of the samples varied between 878 and 36,000 ppm, despite the fact that the U.S. Food and Drug Administration (FDA) has determined that the limit for mercury in creams should be less than 1 ppm. Skin creams containing mercury are still available and commonly used in Mexico and many developing countries, and their contents are poorly controlled.

Do Animals Talk? Do Animals Talk? Nature Bulletin No. 635 April 1, 1961 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist DO ANIMALS TALK ? Amateur bird fans are not all bird watchers. Some of us are bird listeners. In the forest preserves and rural regions, the big black noisy crow is a continual challenge. At the first light of dawn an evenly spaced "caw, caw, caw" seems to say "Hello! Is anybody awake?" Soon it is answered by sleepy crow voices. They have food calls, assembly calls, alarm calls, courtship calls and a lot of squabbling over roosting spots as they settle down for the night. The adults are very quiet near the nest but the fledglings make loud gargling sounds as they are fed. The discovery of an owl or cat sets off a sort of mob hysteria. By hiding a microphone among a flock of crows it has been found that they also talk in whispers.

Margin turnaround at hand: reprieve for US refiners  

SciTech Connect

After unseasonal US gasoline price deterioration during the summer driving months, a turnaround in rack (unbranded, undelivered wholesale) prices is helping to reverse the downward trend in refining margins on the Gulf Coast. In turn, the improved margins are buoying up light crude oil prices in the US Gulf Coast and strengthening spot-market prices. A graph tracks apparent margins on four important crudes utilized on the US Gulf Coast. August 1984 saw negative margins even for heavy Venezuelan Lagunillas (15/sup 0/ API) and Mexican Maya (22/sup 0/ API), but both were again positive in September. Energy Detente refining netback data for September 1984 are presented for the US Gulf Coast, the US West Coast, Rotterdam, and Singapore. The fuel price/tax series and industrial fuel prices are presented for September 1984 for countries of the Western Hemisphere.

1 Regulation of Gas Marketing Activities in Mexico  

E-Print Network (OSTI)

We study linking the Mexican market for natural gas with the North American market and the implications of these links on efficient marketing of gas in Mexico. We argue that PEMEX should be permitted to enter into spot contracts or future contracts to sell gas, however, the price of gas should always be the net back price based on the Houston Ship Channel at the time of delivery. PEMEX should not be permitted to discount the price of gas from the Houston netback price even in a nondiscriminatory fashion. This arrangement is transparent, it is easy to enforce and does not eliminate any legitimate market options for any of the parties involved. PEMEX or consumers of gas can use the Houston market for hedging of speculative transactions.

Process-level composition of executable web services: ”on-the-fly” versus ”once-for-all” composition  

E-Print Network (OSTI)

Most of the work on automated composition of web services has focused so far on the problem of composition at the functional level, i.e., composition of atomic services that can be executed in a single request-response step. In this paper, we address the problem of automated composition at the process level, i.e., a composition that takes into account that executing a web service requires interactions that may involve different sequential, conditional, and iterative steps. We define two kinds of process-level composition problems: on-the-fly compositions that satisfy one-shot user requests specified as composition goals, and a more general form, called once-for-all compositions, whose goal is to build a general composed web service that is able to interact directly with the users, receive requests from them, and propose suitable answers. We propose a solution to these two kinds of process-level compositions, and apply the solution to the case of web services described in OWL-S. As a result, we automatically generate process-level compositions as executable OWL-S process models. We show that, while executable on-the-fly compositions can be described as standard OWL-S process models, once-for-all compositions need OWL-S process models to be extended with receive and reply constructs.

Wildlife and Wildlife Habitat Loss Assessment Summary at Federal Hydroelectric Facilities; Willamette River Basin, 1985 Final Report.  

DOE Green Energy (OSTI)

Habitat based assessments were conducted of the US Army Corps of Engineers' hydroelectric projects in the Willamette River Basin, Oregon, to determine losses or gains to wildlife and/or wildlife habitat resulting from the development and operation of the hydroelectric-related components of the facilities. Preconstruction, postconstruction, and recent vegetation cover types at the project sites were mapped based on aerial photographs. Vegetation cover types were identified within the affected areas and acreages of each type at each period were determined. Wildlife target species were selected to represent a cross-section of species groups affected by the projects. An interagency team evaluated the suitability of the habitat to support the target species at each project for each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the projects. The Willamette projects extensively altered or affected 33,407 acres of land and river in the McKenzie, Middle Fork Willamette, and Santiam river drainages. Impacts to wildlife centered around the loss of 5184 acres of old-growth conifer forest, and 2850 acres of riparian hardwood and shrub cover types. Impacts resulting from the Willamette projects included the loss of critical winter range for black-tailed deer and Roosevelt elk, and the loss of year-round habitat for deer, upland game birds, furbearers, spotted owls, pileated woodpeckers, and many other wildlife species. Bald eagles and ospreys were benefited by an increase in foraging habitat. The potential of the affected areas to support wildlife was greatly altered as a result of the Willamette projects. Losses or gains in the potential of the habitat to support wildlife will exist over the lives of the projects. Cumulative or system-wide impacts of the Willamette projects were not quantitatively assessed.

Wildlife and Wildlife Habitat Loss Assessment at Detroit Big Cliff Dam and Reservoir Project, North Santiam River, Oregon, 1985 Final Report.  

DOE Green Energy (OSTI)

A habitat based assessment was conducted of the US Army Corps of Engineers' Detroit/Big Cliff Dam and Reservoir Project (Detroit Project) on the North Santiam River, Oregon, to determine losses or gains resulting from the development and operation of the hydroelectric-related components of the project. Preconstruction, postconstruction, and recent vegetation cover types at the project site were mapped based on aerial photographs from 1939, 1956, and 1979, respectively. Vegetation cover types were identified within the affected area and acreages of each type at each time period were determined. Ten wildlife target species were selected to represent a cross-section of species groups affected by the project. An interagency team evaluated the suitability of the habitat to support the target species at each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the project. The Detroit Project extensively altered or affected 6324 acres of land and river in the North Santiam River drainage. Impacts to wildlife centered around the loss of 1,608 acres of conifer forest and 620 acres of riparian habitat. Impacts resulting from the Detroit Project included the loss of winter range for black-tailed deer and Roosevelt elk, and the loss of year-round habitat for deer, river otter, beaver, ruffed grouse, pileated woodpecker, spotted owl, and many other wildlife species. Bald eagle and osprey were benefited by an increase in foraging habitat. The potential of the affected area to support wildlife was greatly altered as a result of the Detroit Project. Losses or gains in the potential of the habitat to support wildlife will exist over the life of the project.

A Formal Ontology Reasoning with Individual Optimization: A Realization of the Semantic Web  

E-Print Network (OSTI)

Abstract. Answering a query over a group of RDF data pages is a trivial process. However, in the Semantic Web, there is a need for ontology technology. Consequently, OWL, a family of web ontology languages based on description logic, has been proposed for the Semantic Web. Answering a query over the SemanticWeb is thus not trivial, but a deductive process. However, the reasoning on OWL with data has an efficiency problem. Thus, we introduce optimization techniques for the inference algorithm. This work demonstrates the techniques for instance checking and instance retrieval problems with respect to ALC description logic which covers certain parts of OWL. 1
