A letter report issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) is estimated to cost about $787 billion over the next several years, of which about $280 billion will be administered through states and localities. The Recovery Act requires GAO to do bimonthly reviews of the use of funds by selected states and localities. In this first report, GAO describes selected states' and localities' (1) uses of and planning of Recovery Act funds, (2) accountability approaches, and (3) plans to evaluate the impact of funds received. GAO's work is focused on 16 states and the District of Columbia--representing about 65 percent of the U.S. population and two-thirds of the intergovernmental federal assistance available through the Recovery Act. GAO collected documents from and interviewed state and local officials, including Governors, "Recovery Czars," State Auditors, Controllers, and Treasurers. GAO also reviewed guidance from the Office of Management and Budget (OMB) and other federal agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2007, federal agencies worked with over 160,000 contractors, obligating over $456 billion, to help accomplish federal missions. This reliance on contractors makes it critical that agencies have the information necessary to properly evaluate a contractor's prior history of performance and better inform agencies' contract award decisions. While actions have been taken to improve the sharing of past performance information and its use--including the development of the Past Performance Information Retrieval System (PPIRS)--concerns remain about this information. This report assesses agencies' use of past performance information in awarding contracts; identifies challenges that hinder systematic sharing of past performance information; and describes efforts to improve contractor performance information. In conducting this work, GAO analyzed 62 contract solicitations from fiscal years 2007 and 2008 and met with 121 contracting officials. While the solicitations represent a range of contracts and contractors, GAO's findings cannot be generalized to all federal contracts."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), with the aid of the National Aeronautics and Space Administration (NASA), plans to procure the next generation of geostationary operational environmental satellites, called the Geostationary Operational Environmental Satellite-R series (GOES-R). GOES-R is to replace the current series of satellites, which will likely begin to reach the end of their useful lives in 2014. This series is considered critical to the United States' ability to maintain the continuity of data required for weather forecasting through the year 2028. GAO was asked to summarize its report being released today that (1) determines the status of the GOES-R program, (2) evaluates whether plans for the acquisition address problems experienced on similar programs, and (3) determines whether NOAA's plan will be adequate to support current data requirements."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's work examining the uses and planning by selected states and localities for funds made available by the American Recovery and Reinvestment Act of 2009 (Recovery Act). The Recovery Act is estimated to cost about $787 billion over the next several years, of which about $280 billion will be administered through states and localities. Funds made available under the Recovery Act are being distributed to states, localities, and other entities and individuals through a combination of grants and direct assistance. As Congress may know, the stated purposes of the Recovery Act are to: (1) preserve and create jobs and promote economic recovery; (2) assist those most impacted by the recession; (3) provide investments needed to increase economic efficiency by spurring technological advances in science and health; (4) invest in transportation, environmental protection, and other infrastructure that will provide long-term economic benefits; and (5) stabilize state and local government budgets, in order to minimize and avoid reductions in essential services and counterproductive state and local tax increases. As described in GAO's March testimony, the Recovery Act specifies several roles for GAO including conducting bimonthly reviews of …

A letter report issued by the Government Accountability Office with an abstract that begins "The turmoil in financial markets and the economic downturn has brought significant financial stress to the auto manufacturing industry. The economic reach of the auto industry in the United States is broad, affecting autoworkers, auto suppliers, stock and bondholders, dealers, and certain states. To help stabilize the U.S. auto industry and avoid disruptions that could pose systemic risk to the nation's economy, in December 2008 the Department of the Treasury established the Automotive Industry Financing Program (AIFP) under the Troubled Asset Relief Program (TARP). From December 2008 through March 2009, Treasury has allocated about $36 billion to this program, including loans to Chrysler Holding LLC (Chrysler) and General Motors (GM). GAO has previously identified three principles to guide federal assistance to large firms: define the problem, determine the national interests and set goals and objectives, and protect the government's interests. As part of GAO's statutorily mandated responsibilities to provide timely oversight of TARP activities, this report discusses the (1) nature and purpose of assistance to the auto industry, (2) how the assistance addresses the three principles, and (3) important factors for Chrysler and GM to address …

This report reviews the history and trends of oil spills in the United States; identifies the legal authorities governing oil spill prevention, response, and cleanup; and examines the threats of future oil spills in U.S. coastal waters.

The nature of plasma equilibrium in a magnetic field with stochastic regions is examined. It is shown that the magnetic differential equation that determines the equilibrium Pfirsch-Schluter currents can be cast in a form similar to various nonlinear equations for a turbulent plasma, allowing application of the mathematical methods of statistical turbulence theory. An analytically tractable model, previously studied in the context of resonance-broadening theory, is applied with particular attention paid to the periodicity constraints required in toroidal configurations. It is shown that even a very weak radial diffusion of the magnetic field lines can have a significant effect on the equilibrium in the neighborhood of the rational surfaces, strongly modifying the near-resonant Pfirsch-Schluter currents. Implications for the numerical calculation of 3D equilibria are discussed

This paper presents a theoretical framework for understanding plasma turbulence in astrophysical plasmas. It is motivated by observations of electromagnetic and density fluctuations in the solar wind, interstellar medium and galaxy clusters, as well as by models of particle heating in accretion disks. All of these plasmas and many others have turbulentmotions at weakly collisional and collisionless scales. The paper focuses on turbulence in a strong mean magnetic field. The key assumptions are that the turbulent fluctuations are small compared to the mean field, spatially anisotropic with respect to it and that their frequency is low compared to the ion cyclotron frequency. The turbulence is assumed to be forced at some system-specific outer scale. The energy injected at this scale has to be dissipated into heat, which ultimately cannot be accomplished without collisions. A kinetic cascade develops that brings the energy to collisional scales both in space and velocity. The nature of the kinetic cascade in various scale ranges depends on the physics of plasma fluctuations that exist there. There are four special scales that separate physically distinct regimes: the electron and ion gyroscales, the mean free path and the electron diffusion scale. In each of the scale ranges separated …

In searching for high gravimetric and volumetric density hydrogen storage systems, it is inevitable that higher energy density materials will be used. In order to make safe and commercially acceptable condensed phase hydrogen storage systems, it is important to understand quantitatively the risks involved in using and handling these materials and to develop appropriate mitigation strategies to handle potential material exposure events. A crucial aspect of the development of risk identification and mitigation strategies is the development of rigorous environmental reactivity testing standards and procedures. This will allow for the identification of potential risks and implementation of risk mitigation strategies. Modified testing procedures for shipping air and/or water sensitive materials, as codified by the United Nations, have been used to evaluate two potential hydrogen storage materials, 2LiBH{sub 4} {center_dot} MgH{sub 2} and NH{sub 3}BH{sub 3}. The modified U.N. procedures include identification of self-reactive substances, pyrophoric substances, and gas-emitting substances with water contact. The results of these tests for air and water contact sensitivity will be compared to the pure material components where appropriate (e.g. LiBH{sub 4} and MgH{sub 2}). The water contact tests are divided into two scenarios dependent on the hydride to water mole ratio and heat transport characteristics. …

Radioactive wastes are confined in 49 underground storage tanks at the Savannah River Site. The tanks are examined by ultrasonic (UT) methods for thinning, pitting, and stress corrosion cracking in order to assess fitness-for-service. During an inspection in 2002, ten cracks were identified on one of the tanks. Given the location of the cracks (i.e., adjacent to welds, weld attachments, and weld repairs), fabrication details (e.g., this tank was not stress-relieved), and the service history the degradation mechanism was stress corrosion cracking. Crack instability calculations utilizing API-579 guidance were performed to show that the combination of expected future service condition hydrostatic and weld residual stresses do not drive any of the identified cracks to instability. The cracks were re-inspected in 2007 to determine if crack growth had occurred. During this re-examination, one indication that was initially reported as a 'possible perpendicular crack <25% through wall' in 2002, was clearly shown not to be a crack. Additionally, examination of a new area immediately adjacent to other cracks along a vertical weld revealed three new cracks. It is not known when these new cracks formed as they could very well have been present in 2002 as well. Therefore, a total of twelve …

Isotopes are vital to the science and technology base of the US economy. Isotopes, both stable and radioactive, are essential tools in the growing science, technology, engineering, and health enterprises of the 21st century. The scientific discoveries and associated advances made as a result of the availability of isotopes today span widely from medicine to biology, physics, chemistry, and a broad range of applications in environmental and material sciences. Isotope issues have become crucial aspects of homeland security. Isotopes are utilized in new resource development, in energy from bio-fuels, petrochemical and nuclear fuels, in drug discovery, health care therapies and diagnostics, in nutrition, in agriculture, and in many other areas. The development and production of isotope products unavailable or difficult to get commercially have been most recently the responsibility of the Department of Energy's Nuclear Energy program. The President's FY09 Budget request proposed the transfer of the Isotope Production program to the Department of Energy's Office of Science in Nuclear Physics and to rename it the National Isotope Production and Application program (NIPA). The transfer has now taken place with the signing of the 2009 appropriations bill. In preparation for this, the Nuclear Science Advisory Committee (NSAC) was requested to …

Individual raw data streams from instrumentation at the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility (ACRF) fixed and mobile sites are collected and sent to the Data Management Facility (DMF) at Pacific Northwest National Laboratory (PNNL) for processing in near real-time. Raw and processed data are then sent daily to the ACRF Archive, where they are made available to users. For each instrument, we calculate the ratio of the actual number of data records received daily at the Archive to the expected number of data records. The results are tabulated by (1) individual data stream, site, and month for the current year and (2) site and fiscal year (FY) dating back to 1998. The U.S. Department of Energy (DOE) requires national user facilities to report time-based operating data. The requirements concern the actual hours of operation (ACTUAL); the estimated maximum operation or uptime goal (OPSMAX), which accounts for planned downtime; and the VARIANCE [1 - (ACTUAL/OPSMAX)], which accounts for unplanned downtime. The OPSMAX time for the second quarter of FY 2009 for the Southern Great Plains (SGP) site is 2,052.00 hours (0.95 x 2,160 hours this quarter). The OPSMAX for the North Slope Alaska (NSA) locale is 1,944.00 hours …

A general polarization density which consists of classical and neoclassical parts is system-atically derived via modern gyrokinetics and bounce-kinetics by employing a phase-space Lagrangian Lie-transform perturbation method. The origins of polarization density are further elucidated. Extending the work on neoclassical polarization for long wavelength compared to ion banana width [M. N. Rosenbluth and F. L. Hinton, Phys. Rev. Lett. 80, 724 (1998)], an analytical formula for the generalized neoclassical polarization including both finite-banana-width (FBW) and finite-Larmor-radius (FLR) effects for arbitrary radial wavelength in comparison to banana width and gyroradius is derived. In additional to the contribution from trapped particles, the contribution of passing particles to the neoclassical polarization is also explicitly calculated. Our analytic expression agrees very well with the previous numerical results for a wide range of radial wavelength.

Geological sequestration has the potential capacity and longevity to significantly decrease the amount of anthropogenic CO2 introduced into the atmosphere by combustion of fossil fuels such as coal. Effective sequestration, however, requires the ability to verify the integrity of the reservoir and ensure that potential leakage rates are kept to a minimum. Moreover, understanding the pathways by which CO2 migrates to the surface is critical to assessing the risks and developing remediation approaches. Field experiments, such as those conducted at the Zero Emissions Research and Technology (ZERT) project test site in Bozeman, Montana, require a flexible CO2 monitoring system that can accurately and continuously measure soil-surface CO2 fluxes for multiple sampling points at concentrations ranging from background levels to several tens of percent. To meet this need, PNNL is developing a multi-port battery-operated system capable of both spatial and temporal monitoring of CO2 at concentrations from ambient to at least 150,000 ppmv. This report describes the system components (sampling chambers, measurement and control system, and power supply) and the results of a field test at the ZERT site during the late summer and fall of 2008. While the system performed well overall during the field test, several improvements to the …

Nano-scale mechanical forces generated by motor proteins are crucial to normal cellular and organismal functioning. The ability to measure and exploit such forces would be important to developing motile biomimetic nanodevices powered by biological motors for Nanomedicine. Axonemal dynein motors positioned inside the sperm flagellum drive microtubule sliding giving rise to rhythmic beating of the flagellum. This force-generating action makes it possible for the sperm cell to move through viscous media. Here we report new nano-scale information on how the propulsive force is generated by the sperm flagellum and how this force varies over time. Single cell recordings reveal discrete {approx}50 ms pulses oscillating with amplitude 9.8 {+-} 2.6 nN independent of pulse frequency (3.5-19.5 Hz). The average work carried out by each cell is 4.6 x 10{sup -16} J per pulse, equivalent to the hydrolysis of {approx}5,500 ATP molecules. The mechanochemical coupling at each active dynein head is {approx}2.2 pN/ATP, and {approx}3.9 pN per dynein arm, in agreement with previously published values obtained using different methods.

Testimony issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, the Department of Defense (DOD) obligated over $200 billion on contracts for services, which accounted for more than half of its total contract obligations. Given the serious budget pressures facing the nation, it is critical that DOD obtain value when buying these services. Yet DOD does not always use sound practices when acquiring services, and the department lacks sufficient people with the right skills to support its acquisitions. Although DOD has ongoing efforts to improve its planning, execution, and oversight of service acquisitions, many concerns that prompted GAO to put DOD contract management on its high-risk list in 1992 remain. The committee asked GAO to address challenges facing DOD in measuring the value from and risks associated with its contracting for services. This testimony provides an overview of key concerns GAO cited in its previous reports. Specifically it focuses on (1) challenges DOD faces in following sound contract and contracting management practices and (2) recent actions DOD has taken to improve its management of service contracting. GAO has made numerous recommendations over the past decade aimed at improving DOD's management and oversight of service …
