Opportunities to Improve Timeliness of IRS Lien Releases

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "Among the Internal Revenue Service's (IRS) many tools to collect outstanding taxes is its ability to use the property of a taxpayer as security for an outstanding tax debt. IRS exercises this power when it files a federal tax lien against the property of a taxpayer. As part of its tax collection activities, IRS reported filing more than 548,000 tax liens against taxpayer property in fiscal year 2003. Sin… more

Particulate Matter Air Quality Standards: Background and Current Developments

Description: Following a brief summary of recent developments regarding the implementation and re-evaluation of the 1997 standards, this report provides a broad overview of the standard-setting process, followed by a description of revisions to earlier standards, legal challenges to the 1997 standard, and particulate matter health effects research. EPA’s ongoing progress in reviewing the 1997 standard is then summarized. Other activities that potentially impact the implementation and review of the particula… more

General computational spectroscopic framework applied to Z-pinch dynamic hohlraum K-shell argon spectra

Description: We describe a general computational spectroscopic framework for interpreting observed spectra. The framework compares synthetic spectra with measured spectra, then optimizes the agreement using the Dakota toolkit to minimize a merit function that incorporates established spectroscopic techniques. We generate synthetic spectra using the self-consistent nonlocal thermodynamic equilibrium atomic kinetics and radiative transfer code Cretin, relativistic atomic structure and cross section data from … more

Migration and Entrapment of DNAPLs in Heterogeneous Systems: Impact of Waste and Porous Medium Composition

Description: Dense nonaqueous phase liquids (DNAPLs) pose a significant threat to soil and groundwater at Department of Energy (DOE) sites. Evidence suggests that subsurface wettability variations are present at many of these sites as a result of spatical and temporal variations in aqueous phase chemistry, contaminant aging, mineralogy and organic matter. The presence of such heterogeneity may significantly influence DNAPL migration and entrapment in the saturated zone.

Microscopic failure behavior of nanoporous Gold

Description: Nanoporous metals have recently attracted considerable interest fueled by potential sensor and actuator applications. One of the key issues in this context is the synthesis of high yield strength materials. Nanoporous Au (np-Au) has been suggested as a candidate due to its monolithic character. The material can be synthesized by dealloying Ag-Au alloys, and exhibits an open sponge-like morphology of interconnecting Au ligaments with a typical pore size distribution on the nanometer length scale… more

Influence Of Coal Combustion Flue Gas Desulfurization Waste On Element Uptake By Maize (Zea Mays L.)

Description: A greenhouse study was conducted to determine the effect of coal combustion flue gas desulfurization (FGD) waste from a coal combustion electric power facility on element uptake by maize (Zea mays L.). Unweathered FGD was applied to an Orangeburg Series (Typic Paleudult) soil with an initial soil pH salt of 4.90. The FGD was added at 0, 1, 2, 4, 6, 8, and 10 per cent by weight. The test plant, maize, was harvested after 6 weeks of growth. Within 56 days of the FGD application, all rates of FGD … more

Thermal Analysis of the SAFKEG Package for Long Term Storage

Description: Interim plutonium storage for up to 10 years in the K-reactor building is currently being planned at Savannah River Site (SRS). SAFKEG package could be used to store Pu metal and oxide (PuO2) in the K-reactor complex with other packagings like 9975. The SAFKEG is designed for carrying Type-B materials across the DOE complex and meets the 10CFR71 requirements. Thermal analyses were performed to ensure that the temperatures of the SAFKEG components will not exceed their temperature limits under t… more

Covariance matrices for nuclear cross sections derived from nuclear model calculations.

Description: The growing need for covariance information to accompany the evaluated cross section data libraries utilized in contemporary nuclear applications is spurring the development of new methods to provide this information. Many of the current general purpose libraries of evaluated nuclear data used in applications are derived either almost entirely from nuclear model calculations or from nuclear model calculations benchmarked by available experimental data. Consequently, a consistent method for gene… more

Transverse-momentum dependent modification of dynamic texture in central Au+Au collisions at sqrt(sNN) = 200 GeV

Description: Correlations in the hadron distributions produced in relativistic Au+Au collisions are studied in the discrete wavelet expansion method. The analysis is performed in the space of pseudorapidity (|{eta}| {le} 1) and azimuth (full 2{pi}) in bins of transverse momentum (p{sub t}) from 0.14 {le} p{sub t} {le} 2.1 GeV/c. In peripheral Au+Au collisions a correlation structure ascribed to minijet fragmentation is observed. It evolves with collision centrality and p{sub t} in a way not seen before whic… more

Electron-Density Scaling of Conversion Efficiency of Laser Energy into L-shell X-rays

Description: Laser-produced plasmas at subcritical densities have proven to be efficient sources for x-ray production. In this context, they obtain new results from experiments performed in Kr and Xe gas-filled targets that were irradiated by the high-power OMEGA (Laboratory for Laser Energetics, University of Rochester) laser. Nearly 40% of the laser energy was converted into x-rays in the L-shell-photon-energy range ({ge} 1.6 keV) by a Kr-filled target. The conversion efficiency measurements were correlat… more
