A letter report issued by the Government Accountability Office with an abstract that begins "Since 2003, a global epidemic of avian influenza has raised concern about the risk of an influenza pandemic among humans, which could cause millions of deaths. The United States and its international partners have begun implementing a strategy to forestall (prevent or delay) a pandemic and prepare to cope should one occur. Disease experts generally agree that the risk of a pandemic strain emerging from avian influenza in a given country varies with (1) environmental factors, such as disease presence and certain high-risk farming practices, and (2) preparedness factors, such as a country's capacity to control outbreaks. This report describes (1) U.S. and international efforts to assess pandemic risk by country and prioritize countries for assistance and (2) steps that the United States and international partners have taken to improve the ability to forestall a pandemic. To address these objectives, we interviewed officials and analyzed data from U.S. agencies, international organizations, and nongovernmental experts. The U.S. and international agencies whose efforts we describe reviewed a draft of this report. In general, they concurred with our findings. Several provided technical comments, which we incorporated as appropriate."

A letter report issued by the Government Accountability Office with an abstract that begins "The Uniformed Services Employment and Reemployment Rights Act of 1994 (USERRA) protects the employment and reemployment rights of federal and nonfederal employees who leave their employment to perform military service. The Department of Labor (DOL) investigates and attempts to resolve claims filed by servicemembers, and if not successful, DOL is to inform the federal claimants that they may request to have their claims referred to the Office of Special Counsel (OSC). Under a demonstration project, from February 8, 2005, through September 30, 2007, OSC is authorized to receive and investigate certain USERRA claims, with DOL continuing its investigative role for others. As required by Pub. L. No. 108-454, this report describes the (1) processes, (2) outcomes, and (3) major changes during the demonstration project. GAO selected a random sample of cases from DOL's and OSC's databases and traced data for selected elements from the electronic files to source case files."

A letter report issued by the Government Accountability Office with an abstract that begins "To better understand how changes in domestic and international petroleum products markets have affected prices, GAO was asked to evaluate trends in (1) the international trade of petroleum products, (2) refining capacity and intensity of refining capacity use internationally and in the United States, (3) international and domestic crude oil and petroleum product inventories, and (4) domestic petroleum supply infrastructure. To address these objectives, we reviewed numerous studies, evaluated data, and spoke to many industry officials and experts and agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Growing debt and net interest costs are a result of persistent fiscal imbalances, which, if left unchecked, threaten to crowd out spending for other national priorities. The return on every federal dollar that the Department of the Treasury (Treasury) is able to invest represents an opportunity to reduce interest costs. This report (1) analyzes trends in Treasury's main receipts, expenditures, and cash balances, (2) describes Treasury's current investment strategy, and (3) identifies options for Treasury to consider for improving its return on short-term investments. GAO held interviews with Treasury officials and others and reviewed related documents."

A letter report issued by the Government Accountability Office with an abstract that begins "Intermodal transportation enables freight and passengers to cross between different modes of transportation efficiently and can improve mobility, reduce congestion, and cut costs. In 1991 Congress called for a National Intermodal Transportation System and created the Office of Intermodalism within the Department of Transportation (DOT). However, as GAO and others have reported, there are barriers to planning and implementing intermodal projects. GAO's report examines (1) barriers that inhibit intermodal transportation; (2) actions DOT has taken to address these barriers and support Congress' goal; and (3) additional actions, if any, that DOT could take to better address barriers. GAO analyzed information from DOT and transportation experts and talked with transportation officials from various states and localities throughout the country."

A letter report issued by the Government Accountability Office with an abstract that begins "One proven approach for improving tax compliance is information reporting to the Internal Revenue Service (IRS) by third parties about taxpayers' income and expenses. IRS matches information returns with taxpayers' income tax returns to see if taxpayers have filed returns and reported all their income. The administration's fiscal year 2008 budget proposed requiring information reporting on merchant payment card reimbursements and on certain payments to corporations, raising an estimated $18.4 billion over 10 years. This report's objectives are to (1) identify, using case studies, the compliance costs of existing information reporting; (2) determine the kinds of third-party compliance costs that may result from the two budget proposals and options for mitigating the costs; and (3) determine IRS's ability to process and use additional information returns. GAO did nongeneralizable structured interviews with four payers volunteering information and with five companies filing a sizable percentage of all information returns. GAO's work also included reviewing studies and documentation and contacting other government and nongovernment parties."

A letter report issued by the Government Accountability Office with an abstract that begins "In December 2000, the Department of Energy (DOE) awarded Bechtel National, Inc. (Bechtel) a contract to design and construct the Waste Treatment Plant (WTP), one of the largest nuclear waste cleanup projects in the nation. Originally expected to cost $4.3 billion and be completed in 2011, DOE now estimates that WTP will cost over $12.2 billion and be completed in late 2019. Weaknesses in DOE's management and oversight of contractors led GAO to designate DOE contract management as a high-risk area since 1990. GAO was asked to determine whether (1) DOE's internal controls are designed to provide reasonable assurance against improper WTP payments and (2) DOE's controls reasonably ensure proper accountability for WTP assets. GAO reviewed fiscal year 2005 and 2006 internal controls by analyzing data and documents, interviewing DOE and contractor staff, and physically observing property items."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has increasingly relied on reserve personnel to carry out its military operations. Congress and DOD have taken steps to enhance reserve compensation, such as improving health care benefits. Concerns exist, however, that rising compensation costs may not be sustainable in the future, especially given the nation's large and growing long-range fiscal imbalance. Under the statutory authority of the Comptroller General to conduct work on his own initiative, GAO (1) reviewed how much it has cost the federal government to compensate reserve personnel since fiscal year 2000; (2) assessed the extent to which DOD's mix of cash, noncash, and deferred compensation has helped DOD meet its human capital goals; and (3) evaluated the extent to which DOD's approach to reserve compensation provides transparency over total cost to the federal government. To address these objectives, GAO analyzed budget data and relevant legislation and also interviewed appropriate officials. GAO focused this review on part-time reservists and full-time, active guard and reserve."

A letter report issued by the Government Accountability Office with an abstract that begins "While aviation accidents in the United States are relatively infrequent, recent incidents have heightened concerns about safety on airport runways and ramps. As the nation's aviation system becomes more crowded every day, increased congestion at airports may exacerbate ground safety concerns. To safely handle the anticipated larger volumes of air traffic, the Federal Aviation Administration (FAA) is implementing the Next Generation Air Transportation System (NextGen) to better manage air traffic both in the air and on the ground. GAO was asked to evaluate (1) the progress being made in addressing runway safety and what additional measures, if any, could be taken and (2) the factors affecting progress in improving ramp safety and what is being done by FAA and others to address those factors. We reviewed runway and ramp safety data, interviewed agency officials and industry stakeholders, and surveyed experts."

A letter report issued by the Government Accountability Office with an abstract that begins "A growing portion of federal spending is related to buying services such as administrative, management, and information technology support. Services accounted for about 60 percent of total fiscal year 2006 procurement dollars. The Services Acquisition Reform Act (SARA) of 2003 established a Services Acquisition Advisory Panel to make recommendations for improving acquisition practices. In January 2007, the panel proposed 89 recommendations to improve federal acquisition practices. GAO was asked to determine how the panel recommendations compare to GAO's past work and identify how the Office of Federal Procurement Policy (OFPP) expects the recommendations to be addressed. To do this, GAO analyzed the panel report and compared its findings and recommendations to GAO's past work and recommendations, obtained OFPP's views on how it expected the recommendations to be implemented, and reviewed proposed legislation in Congress to determine if legislative provisions had the potential to address some recommendations."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1990, GAO has designated the National Aeronautics and Space Administration's (NASA) contract management as an area of high risk in part because it lacked modern systems to provide accurate and reliable information on contract spending. In April 2000, NASA began a system modernization effort, known as the Integrated Enterprise Management Program (IEMP). When GAO last reported on the status of IEMP in September 2005, NASA had begun to implement disciplined processes needed to manage IEMP, but had yet to implement other best practices such as adopting business processes that improve information on contract spending. This GAO report addresses (1) actions taken by NASA to effectively implement the disciplined processes needed to manage IEMP and (2) the extent to which NASA has considered the strategic issues associated with developing a concept of operations and defining standard business processes. GAO interviewed NASA officials and obtained and analyzed documentation relevant to the issues."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Marine Fisheries Service (NMFS) developed the Atlantic Large Whale Take Reduction (ALWTR) plan to protect endangered large whales from entanglements in commercial fishing gear, which can cause injury or death. Because whales continued to die after the ALWTR plan went into effect, NMFS proposed revisions in 2005. GAO was asked to review these proposed revisions, including (1) their scientific basis and uncertainties regarding their effectiveness, (2) NMFS's plans to address concerns about the feasibility of implementing them, (3) the extent to which NMFS fully assessed the costs to the fishing industry and impacts on fishing communities, and (4) the extent to which NMFS developed strategies for fully evaluating their effectiveness. GAO reviewed the proposed changes to the ALWTR plan and obtained the views of NMFS officials, industry representatives, scientists, and conservationists."

A letter report issued by the Government Accountability Office with an abstract that begins "Every year, disease and other conditions kill about 10 million children younger than 5 years, and more than 500,000 women die from pregnancy and childbirth-related causes. To help improve their health, Congress created the Child Survival and Health Programs Fund. The 2006 Foreign Operations Appropriations Act directed GAO to review the U.S. Agency for International Development's (USAID) use of the fund for fiscal years 2004 and 2005. Committees of jurisdiction indicated their interest centered on the Child Survival and Maternal Health (CS/MH) account of the fund. GAO examined USAID's (1) allocations, obligations, and expenditures of CS/MH funds; (2) activities undertaken with those funds; (3) methods for disseminating CS/MH information; and (4) response to challenges to its CS/MH programs. GAO conducted surveys of 40 health officers, visited USAID missions in four countries, interviewed USAID officials, and reviewed data."

A letter report issued by the Government Accountability Office with an abstract that begins "In the past 16 years, a number of laws, accounting standards, system requirements, and related guidance have emphasized the need for cost information in the federal government, establishing requirements and accounting standards for managerial cost accounting (MCA) information. In light of these requirements, GAO was asked to determine how federal agencies generate MCA information and how government managers use that information to support their decisions and provide accountability. Since 2005, GAO has reviewed and reported on MCA practices at 10 large civilian agencies resulting in five reports. This report brings the overall observations of these studies together in one place."

A letter report issued by the Government Accountability Office with an abstract that begins "An influenza pandemic could impair the military's readiness, jeopardize ongoing military operations abroad, and threaten the day-to-day functioning of the Department of Defense (DOD) due to a large percentage of sick or absent personnel. GAO was asked to examine DOD's pandemic influenza planning and preparedness efforts. GAO previously reported that DOD had taken numerous actions to prepare departmentwide, but faced four management challenges as it continued its efforts. GAO made recommendations to address these challenges and DOD generally concurred with them. This report focuses on DOD's combatant commands (COCOM) and addresses (1) actions the COCOMs have taken to prepare and (2) management challenges COCOMs face going forward. GAO reviewed guidance, plans, and after-action reports and interviewed DOD officials and more than 200 officials at the 9 COCOMs."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government's financial condition and fiscal outlook have deteriorated dramatically since 2000. The federal budget has gone from surplus to deficit and the nation's major reported long-term fiscal exposures--a wide range of programs, responsibilities, and activities that either explicitly or implicitly commit the government to future spending--have more than doubled. Current budget processes and measurements do not fully recognize these fiscal exposures until payments are made. Increased information and better incentives to address the long-term consequences of today's policy decisions can help put our nation on a more sound fiscal footing. Given its interest in accurate and timely information on the U.S. fiscal condition, the Senate Committee on the Budget asked us to update our study of other nations' experiences with accrual budgeting and look at other ways countries have increased attention to their long-term fiscal challenges."

A letter report issued by the Government Accountability Office with an abstract that begins "Airbus S.A.S. (Airbus), a European aircraft manufacturer, is introducing a new aircraft designated as the A380, which is expected to enter service in late 2007. The A380 will be the largest passenger aircraft in the world, with a wingspan of about 262 feet, a tail fin reaching 80 feet high, and a maximum takeoff weight of 1.2 million pounds. The A380 has a double deck and could seat up to 853 passengers. GAO was asked to examine the impact of the A380 on U.S. airports. In May 2006, GAO issued a report that estimated the costs of infrastructure changes at U.S. airports to accommodate the A380. This report discusses (1) the safety issues associated with introducing the A380 at U.S. airports, (2) the potential impact of A380 operations on the capacity of U.S. airports, and (3) how selected foreign airports are preparing to accommodate the A380. To address these issues, GAO reviewed studies on operational and safety issues related to the A380 and conducted site visits to the 18 U.S. airports and 11 Asian, Canadian, and European airports preparing to receive the A380. GAO provided the …

I develop a formulation for Hamiltonian dynamics in an accelerator with magnets whose edges follow a spiral. I demonstrate using this Hamiltonian that a spiral FFAG can be made perfectly 'scaling'. I describe how one computes the RF phase during a rapid acceleration cycle to keep the beam at the appropriate RF phase. I examine the effect of tilting an RF cavity with respect a radial line from the center of the machine, potentially with a different angle than the spiral of the magnets. I discuss partially the effects of the finite energy jumps on the dynamics. This is a status report of work that is still incomplete.

Hydrogen has been identified as a leading candidate to replace petroleum as part of the transition to a sustainable energy system, and major efforts are being conducted worldwide to develop the technologies and supporting activities required for this transition. In the United States, the federal research efforts are led by the U.S. Department of Energy (DOE). The U.S. DOE Hydrogen Program is an integrated inter-office program being conducted by the Office of Energy Efficiency and Renewable Energy, Office of Nuclear Energy (DOE-NE), Office of Fossil Energy and Office of Science. The primary objective of the DOE-NE Nuclear Hydrogen Initiative (NHI) is to develop the nuclear hydrogen production technologies necessary to produce hydrogen at a cost competitive with other alternative transportation fuels. The focus of the NHI is on thermochemical cycles and high temperature electrolysis. The Savannah River National Laboratory (SRNL) has been tasked with the primary responsibility to perform research and development in order to characterize, evaluate and develop the Hybrid Sulfur (HyS) thermochemical process. The HyS Process uses a sulfur dioxide depolarized electrolyzer (SDE) to split water and produce hydrogen. During FY05 and FY06, SRNL designed and conducted proof-of-concept testing for a SDE using a low temperature, PEM fuel …

The twin aspects of energy and control (or direction) are the underlying concepts. Matter and energy are closely linked, and their understanding and control will have overwhelming importance for our civilization, our planet, our science, and our technology. This importance ranges even beyond the large portfolio of BES, both because these truly significant Grand Challenges confront many other realms of science and because even partial solutions to these challenges will enrich scientists’ collective imagination and ability to solve problems with new ideas and new methods.

The MICE coupling coil is fabricated from Nb-Ti, which hashigh quench propagation velocities within the coil in all directionscompared to coils fabricated with other superconductors such as niobiumtin. The time for the MICE coupling coil to become fully normal throughnormal region propagation in the coil is shorter than the time needed fora safe quench (as defined by a hot-spot temperature that is less than 300K). A MICE coupling coil quench was simulated using a code written at theInstitute of Cryogenics and Superconductive Technology (ICST) at theHarbin Institute of Technology (HIT). This code simulates quench backfrom the mandrel as well as normal region propagation within the coil.The simulations included sub-division of the coil. Each sub-division hasa back to back diodes and resistor across the coil. Current flows in theresistor when there is enough voltage across the coil to cause current toflow through the diodes in the forward direction. The effects of thenumber of coil sub-divisions and the value of the resistor across thesub-division on the quench were calculated with and without quench back.Sub-division of the coupling coil reduces the peak voltage to ground, thelayer-to-layer voltage and the magnet hot-spot temperature. Quench backreduces the magnet hot-spot temperature, but the peak voltage to …

We present details about X-ray yields measured with Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories (SNL) diagnostics in soft and moderately hard X-ray bands from laser-driven, doped-aerogel targets shot on 07/14/06 during the OMEGA II test series. Yields accurate to {+-}25% in the 5-15 keV band are measured with Livermore's HENWAY spectrometer. Yields in the sub-keV to 3.2 keV band are measured with LLNL's DANTE diagnostic, the DANTE yields are accurate to 10-15%. SNL ran a PCD-based diagnostic that also measured X-ray yields in the spectral region above 4 keV, and also down to the sub-keV range. The PCD and HENWAY and DANTE numbers are compared. The time histories of the moderately hard (h{nu} > 4 keV) X-ray signals are measured with LLNL's H11 PCD, and from two SNL PCDs with comparable filtration. There is general agreement between the H11 PCD and SNL PCD measured FWHM except for two of the shorter-laser-pulse shots, which is shown not to be due to analysis techniques. The recommended X-ray waveform is that from the SNL PCD p66k10, which was recorded on a fast, high-bandwidth TDS 6804 oscilloscope. X-ray waveforms from target emission in two softer spectral bands are also shown; the …

The 126-B-2, 183-B Clearwells were built as part of the 183-B Water Treatment Facility and are composed of 2 covered concrete reservoirs. The bulk of the water stored in the clearwells was used as process water to cool the 105-B Reactor and as a source of potable water. Residual conditions were determined to meet the remedial action objectives specified in the Remaining Sites ROD through an evaluation of the available process knowledge. The results of the evaluation do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also indicate that residual concentrations are protective of groundwater and the Columbia River.

During the period of August through November 2006, ORISE performed a comprehensive IV at the University of Washington Research and Test Reactor Facility. The objective of the ORISE IV was to validate the licensee’s final status survey processes and data, and to assure the requirements of the DP and FSSP were met.
