We study the buildup of magnetic fields during the formation of Population III star-forming regions, by conducting cosmological simulations from realistic initial conditions and varying the Jeans resolution. To investigate this in detail, we start simulations from identical initial conditions, mandating 16, 32 and 64 zones per Jeans length, and studied the variation in their magnetic field amplification. We find that, while compression results in some amplification, turbulent velocity fluctuations driven by the collapse can further amplify an initially weak seed field via dynamo action, provided there is sufficient numerical resolution to capture vortical motions (we find this requirement to be 64 zones per Jeans length, slightly larger than, but consistent with previous work run with more idealized collapse scenarios). We explore saturation of amplification of the magnetic field, which could potentially become dynamically important in subsequent, fully-resolved calculations. We have also identified a relatively surprising phenomena that is purely hydrodynamic: the higher-resolved simulations possess substantially different characteristics, including higher infall-velocity, increased temperatures inside 1000 AU, and decreased molecular hydrogen content in the innermost region. Furthermore, we find that disk formation is suppressed in higher-resolution calculations, at least at the times that we can follow the calculation. We discuss the …

Correspondence issued by the Government Accountability Office with an abstract that begins "The SNS contains supportive care items for thermal burns, such as bandages, pain medications, intravenous fluids, and topical antimicrobial cream needed for the immediate treatment of burn injuries to reduce the risk of infection and stabilize injured individuals. HHS officials told us that the goal of the SNS is to supplement state and local supplies used for immediate care in the initial response—identified as within 72 hours of sustaining injury. CDC compiled supplies needed for the immediate treatment of burn injuries into kits in 2002 and 2003, based on information provided at that time by burn experts about needed items. Because most medical countermeasures for thermal burns can be found in local hospitals, countermeasures in the SNS would be used to supplement local supplies and inventories, with kits deployed within 24 to 48 hours of notification. The SNS does not contain other countermeasures that may be available for both the immediate care and the longer-term treatment of burn injuries. However, HHS is currently considering whether to acquire some additional countermeasures, including those for longer-term treatment of burn injuries."

The ability of atomic nuclei to emit and absorb photons with energy E{sub {gamma}} is known as the photon strength function f(E{sub {gamma}}). It has direct relevance to astrophysical element formation via neutron capture processes due to its central role in nuclear reactions. Studies of f(E{sub {gamma}}) have benefited from a wealth of data collected in neutron capture and direct reactions but also from newly commissioned inelastic photon scattering facilities. The majority of these experimental methods, however, rely on the use of models because measured {gamma}-ray spectra are simultaneously sensitive to both the nuclear level density and f(E{sub {gamma}}). As excitation energy increases towards the particle separation energies, the level density increases rapidly, creating the quasi-continuum. Nuclear properties in this excitation energy region are best characterized using statistical quantities, such as f(E{sub {gamma}}). A point of contention in studies of the quasi-continuum has been an unexpected and unexplained increase in f(E{sub {gamma}}) at low {gamma}-ray energies (i.e. below E{sub {gamma}} {approx}3 MeV) in a subset of light-to-medium mass nuclei. Ideally, a new model-independent experimental technique is required to address questions regarding the existence and origin of this low-energy enhancement in f(E{sub {gamma}}). Here such a model-independent approach is presented for …

This thesis reports the analysis of the e{sup +}e{sup -} {yields} e{sup +}e{sup -}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}} and e{sup +}e{sup -} {yields} e{sup +}e{sup -}K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0} processes using the final dataset of the BABAR experiment located at the SLAC National Accelerator Laboratory. From previous measurements, the K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}} final state is known to show a clear signal from the {eta}{sub c}(2S) particle. This c{bar c} state escaped detection for almost twenty years and its properties are still not well established on the experimental ground, while accurate predictions exist on the theoretical side. The e{sup +}e{sup -} {yields} e{sup +}e{sup -}K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0} process is first studied in this thesis. An accurate determination of the {eta}{sub c}(2S) properties is obtained in the K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}} decay mode. We also report the first observation of {eta}{sub c}(2S) and other charmonium states to the K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0} final state. The results of this thesis have been published in Physical Review D, and will be useful to test theoretical models describing the charmonium system. The thesis is organized in four chapters. The first one gives a brief introduction …

During discussions about the 2010 Nuclear Posture Review, Congress reviewed and discussed the plans for maintaining and modernizing U.S. strategic nuclear forces. Although the United States plans to reduce the number of warheads deployed on its long-range missiles and bombers, consistent with the terms of the New START Treaty, it also plans to develop new delivery systems for deployment over the next 20-30 years. As a result, the 112th Congress will continue to review these programs during the annual authorization and appropriations process.

We studied the reaction of phenyl radicals (C6H5) with propylene (C3H6) exploiting a high temperature chemical reactor under combustion-like conditions (300 Torr, 1,200-1,500 K). The reaction products were probed in a supersonic beam by utilizing tunable vacuum ultraviolet (VUV) radiation from the Advanced Light Source and recording the photoionization efficiency (PIE) curves at mass-to-charge ratios of m/z = 118 (C9H10+) and m/z = 104 (C8H8+). Our results suggest that the methyl and atomic hydrogen losses are the two major reaction pathways with branching ratios of 86 10 percent and 14 10 percent. The isomer distributions were probed by fitting the recorded PIE curves with a linear combination of the PIE curves of the individual C9H10 and C8H8 isomers. Styrene (C6H5C2H3) was found to be the exclusive product contributing to m/z = 104 (C8H8+), whereas 3-phenylpropene, cis-1-phenylpropene, and 2-phenylpropene with branching ratios of 96 4 percent, 3 3 percent, and 1 1 percent could account for signal at m/z = 118 (C9H10+). Although searched for carefully, no evidence of the bicyclic indane molecule could be provided. The reaction mechanisms and branching ratios are explained in terms of electronic structure calculations nicely agreeing with a recent crossed molecular beam study on this …

A letter report issued by the Government Accountability Office with an abstract that begins "As the responsible DOD agency for leading, advocating, and coordinating all DOD efforts to defeat improvised explosive devices (IED) the Joint IED Defeat Organization (JIEDDO) was directed to develop DOD’s counter-IED strategic plan in February 2006 under DOD Directive 2000.19E. As previously recommended by GAO, JIEDDO has made several attempts to develop such a plan, but its strategic-planning actions have not followed leading strategic-management practices or have since been discontinued. For example, JIEDDO’s 2007 strategic plan did not contain a means of measuring its performance outcomes—a leading strategic-management practice. In addition, JIEDDO’s 2009–2010 strategic plan contained performance measures, but JIEDDO discontinued using these measures because it later determined that the measures were not relevant to the organization’s goals. Although DOD tasked JIEDDO to develop its counter-IED strategic plan, DOD has not translated DOD’s counter-IED general mission objective of eliminating IEDs as a weapon of strategic influence into actionable goals and objectives. JIEDDO issued a new counter-IED strategic plan in January 2012; however, the new plan does not apply to all other counter-IED efforts departmentwide, only to those managed by JIEDDO. Consequently, JIEDDO’s new strategic plan alone …

A letter report issued by the Government Accountability Office with an abstract that begins "DODIG has taken multiple steps, in collaboration with the service IGs in some instances, to improve DOD’s ability to process military whistleblower reprisal cases in a timely manner. Timeliness is important to ensure the reliability of evidence and appropriate resolution of reprisal allegations. However, DODIG has generally not met statutory requirements to report on investigations within 180 days, or to provide alternative notification. DODIG has undertaken efforts to improve timeliness by, for example, eliminating a time-consuming phase of its investigative process. However, DOD’s efforts are hampered by unreliable and incomplete data. For instance, GAO found that DODIG has not consistently or accurately recorded key dates to track how long investigations take to complete. Without key timeliness data, DODIG may have difficulty in identifying process areas requiring improvement and evaluating the impact of reforms. Further, the absence of this information limits congressional decision makers’ ability to provide oversight of DOD’s whistleblower reprisal investigative program."

This report examines the current state of Algeria, including the country's associations with terrorism, despite steady decreases of domestic terrorism; the lessening in power of the Algerian military; and growing oil revenues.

This report discusses the firefighting activities that are traditionally the responsibility of states and local communities. The report also talks about the funding for firefighters, which is provided mostly by state and local governments. However, during the 106th Congress, many in the fire community asserted that local fire departments require and deserve greater support from the federal government.

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has prepared this report to assist Congress in identifying and addressing debt management challenges. Since 1995, the statutory debt limit has been increased 12 times to its current level of $14.294 trillion. The Department of the Treasury (Treasury) recently notified Congress that the current debt limit could be reached as early as April 5, 2011, and the Congressional Budget Office (CBO) projects that under current law debt subject to the limit will exceed $25 trillion in 2021. This report (1) describes the actions that Treasury traditionally takes to manage debt near the limit, (2) analyzes the effects that approaching the debt limit has had on the market for Treasury securities, and (3) describes alternative mechanisms that would permit consideration of the link between policy decisions and the effect on debt when or before decisions are made. GAO analyzed Treasury and market data; interviewed Treasury officials, budget and legislative experts, and market participants; and reviewed practices in selected countries."

The accuracy in the photometry of a point source depends on the point-spread function (PSF), detector pixelization, and observing strategy. The PSF and pixel response describe the spatial blurring of the source, the pixel scale describes the spatial sampling of a single exposure, and the observing strategy determines the set of dithered exposures with pointing offsets from which the source flux is inferred. In a wide-field imaging survey, sources of interest are randomly distributed within the field of view and hence are centered randomly within a pixel. A given hardware configuration and observing strategy therefore have a distribution of photometric uncertainty for sources of fixed flux that fall in the field. In this article we explore the ensemble behavior of photometric and position accuracies for different PSFs, pixel scales, and dithering patterns. We find that the average uncertainty in the flux determination depends slightly on dither strategy, whereas the position determination can be strongly dependent on the dithering. For cases with pixels much larger than the PSF, the uncertainty distributions can be non-Gaussian, with rms values that are particularly sensitive to the dither strategy. We also find that for these configurations with large pixels, pointings dithered by a fractional pixel …

Each year, more than 25 million vehicles reach the end of their service life throughout the world, and this number is rising rapidly because the number of vehicles on the roads is rapidly increasing. In the United States, more than 95% of the 10-15 million scrapped vehicles annually enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, over 75% of automotive materials, primarily the metals, are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobile hulks, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials - commonly called shredder residue - constitutes about 25% of the weight of the vehicle, and it is disposed of in landfills. This practice is not environmentally friendly, wastes valuable resources, and may become uneconomical. …

At the request of the Pacific Northwest National Laboratory, an in-depth analysis of the rapidly evolving state of real estate investments, high-performance building technology, and interest in efficiency was conducted by HaydenTanner, LLC, for the U.S. Department of Energy (DOE) Building Technologies Program. The analysis objectives were • to evaluate the link between high-performance buildings and their market value • to identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to appropriately value and deploy high-performance strategies and technologies across new and existing buildings • to summarize financial mechanisms that facilitate increased investment in these buildings. To meet these objectives, work consisted of a literature review of relevant writings, examination of existing and emergent financial and policy mechanisms, interviews with industry stakeholders, and an evaluation of the value implications through financial modeling. This report documents the analysis methodology and findings, conclusion and recommendations. Its intent is to support and inform the DOE Building Technologies Program on policy and program planning for the financing of high-performance new buildings and building retrofit projects.

Operational wind power forecasting, turbine micrositing, and turbine design require high-resolution simulations of atmospheric flow over complex terrain. The use of both Reynolds-Averaged Navier Stokes (RANS) and large-eddy (LES) simulations is explored for wind energy applications using the Weather Research and Forecasting (WRF) model. To adequately resolve terrain and turbulence in the atmospheric boundary layer, grid nesting is used to refine the grid from mesoscale to finer scales. This paper examines the performance of the grid nesting configuration, turbulence closures, and resolution (up to as fine as 100 m horizontal spacing) for simulations of synoptically and locally driven wind ramping events at a West Coast North American wind farm. Interestingly, little improvement is found when using higher resolution simulations or better resolved turbulence closures in comparison to observation data available for this particular site. This is true for week-long simulations as well, where finer resolution runs show only small changes in the distribution of wind speeds or turbulence intensities. It appears that the relatively simple topography of this site is adequately resolved by all model grids (even as coarse as 2.7 km) so that all resolutions are able to model the physics at similar accuracy. The accuracy of the results …

This report details the chemical and radionuclide contaminant results for the characterization of the 2010 Fourth Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC). Information from this characterization will be used by Liquid Waste Operations (LWO) to support the transfer of low-level aqueous waste from Tank 50 to the Salt Feed Tank in the Saltstone Facility in Z-Area, where the waste will be immobilized. This information is also used to update the Tank 50 Waste Characterization System. The following conclusions are drawn from the analytical results provided in this report: (1) The concentrations of the reported chemical and radioactive contaminants were less than their respective WAC targets or limits unless noted in this section. (2) The reported detection limits for {sup 94}Nb, {sup 247}Cm and {sup 249}Cf are above the requested limits from Reference 2. However, they are below the limits established in Reference 3. (3) There is an estimated concentration of trimethylbenzene (2.25 mg/L). This is not a WAC analyte, but it is the first time this organic compound has been detected in a quarterly WAC sample from Tank 50. (4) The reported detection limit for Norpar 13 is greater than the limit from Table …
