A letter report issued by the Government Accountability Office with an abstract that begins "Pakistan's Federally Administered Tribal Areas (FATA) has been a recognized safe haven for al Qaeda leadership and a base for the Taliban to launch cross-border attacks into Afghanistan. The United States, in an effort to assist Pakistan in addressing this threat, pledged $750 million between 2007 and 2011 to support development activities in the FATA region. This report focuses on (1) the extent U.S. development objectives align with U.S. national security goals and Pakistan's objectives, (2) U.S. efforts to track the pledge, (3) U.S. efforts to measure program performance in the FATA, and (4) efforts to monitor assistance in the FATA. GAO reviewed U.S. and Pakistani documents and interviewed U.S. and Pakistani officials in Washington, D.C., and Pakistan. GAO has prepared this report under the Comptroller General's authority to conduct evaluations on his own initiative."

A letter report issued by the Government Accountability Office with an abstract that begins "Originally established in 2002 to fight terrorism, the Combined Joint Task Force-Horn of Africa (CJTF-HOA), based at Camp Lemonnier, Djibouti, is the military's main operational presence in Africa. The U.S. Africa Command (AFRICOM), created in 2007 to focus on stability in Africa, has been assessing existing activities--as well as CJTF-HOA--against its mission of sustained security engagement in Africa. This report discusses: (1) AFRICOM's decisions on CJTF-HOA's future and whether CJTF-HOA's activities align with the command's mission, and (2) benefits of the task force and challenges it faces. For its review, GAO analyzed AFRICOM and CJTF-HOA guidance, conducted interviews at the command's and task force's headquarters, and obtained perspectives from U.S. embassies in the region."

A letter report issued by the Government Accountability Office with an abstract that begins "Traffic crashes kill or injure millions of people each year. High-quality traffic safety data is vital to allocate resources and target programs as the Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA) and states work to improve traffic safety through data-driven approaches. To qualify for federal funding, states must submit plans which include fatality and crash data analyses to identify areas for improvement. This requested report provides information on (1) the extent to which state traffic safety data systems meet NHTSA performance measures for assessing the quality of data systems, and (2) progress states have made in improving traffic safety data systems, and related challenges. To conduct this work, GAO analyzed state traffic records assessments, visited eight states, and interviewed federal officials and other traffic safety experts."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the U.S. Government Accountability Office's (GAO) budget request for fiscal year 2011. In fiscal year 2009, GAO supported congressional decision making and oversight on a range of critical issues, including the government's efforts to help stabilize financial markets and address the most severe recession since World War II. In addition to providing oversight for the 2008 Economic Stabilization Act and the American Recovery and Reinvestment Act of 2009 (Recovery Act), we continued to provide the Congress updates on programs that are at high risk for waste, fraud, abuse, and mismanagement or are in need of broad reform, and delivered advice and analyses on a broad array of pressing domestic and international issues that demand urgent attention and continuing oversight. These include modernizing the regulatory structure for financial institutions and markets to meet 21st century demands; controlling escalating health care costs and providing more effective oversight of medical products; restructuring the U.S. Postal Service to ensure its financial stability; and improving the Department of Defense's management approaches to issues ranging from weapons system acquisitions to accounting for weapons provided to Afghan security forces. Overall, we responded …

A letter report issued by the Government Accountability Office with an abstract that begins "In 2008 and 2009, the Federal Deposit Insurance Corporation (FDIC) provided emergency assistance that required the Secretary of the Department of the Treasury (Treasury) to make a determination of systemic risk under the systemic risk exception of the Federal Deposit Insurance Act (FDI Act). The FDI Act requires GAO to review each determination made. For the three determinations made to date, this report examines (1) steps taken by FDIC, the Board of Governors of the Federal Reserve System (Federal Reserve), and Treasury to invoke the exception; (2) the basis of the determination and the purpose of resulting actions; and (3) the likely effects of the determination on the incentives and conduct of insured depository institutions and uninsured depositors. To do this work, GAO reviewed agency documentation, relevant laws, and academic studies; and interviewed regulators and market participants."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the United States created two new programs, authorized in Sections 1206 and 1207 of the Fiscal Year 2006 National Defense Authorization Act, to respond to the threats of global terrorism and instability. These programs have provided over $1.3 billion in military and nonmilitary aid to 62 countries and are due to expire in 2011 and 2010, respectively. The Congress mandated that GAO assess the programs. This report addresses the extent to which the programs (1) are consistent with U.S. strategic priorities, (2) are distinct from other programs, (3) address sustainment needs, and (4) incorporate monitoring and evaluation. GAO analyzed data and program documents from the Departments of Defense (DOD) and State (State), and the U.S. Agency for International Development (USAID), and interviewed U.S. and host country officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government spends billions of dollars every year on domestic food assistance programs. The U.S. Department of Agriculture administers most of these programs and monitors the prevalence of food insecurity--that is, the percentage of U.S. households that were unable to afford enough food sometime during the year. Other federal agencies also fund food assistance programs; however, comprehensive and consolidated information on the multiple programs is not readily available. Congress asked GAO to examine: 1) the prevalence of food insecurity in the United States, 2) spending on food assistance programs, 3) what is known about the effectiveness of these programs in meeting program goals, and 4) the implications of providing food assistance through multiple programs and agencies. GAO's steps included analyzing food security and program spending data, analyzing studies on program effectiveness, analyzing relevant federal laws and regulations, conducting site visits, and interviewing relevant experts and officials."

Testimony issued by the Government Accountability Office with an abstract that begins "Since 2003, the Future Combat System (FCS) program has been the centerpiece of the Army's efforts to transition to a lighter, more agile, and more capable combat force. In 2009, however, concerns over the program's performance led to the Secretary of Defense's decision to significantly restructure and ultimately cancel the acquisition program. As a result, the Army is outlining a new approach to ground force modernization. This statement outlines the Army's preliminary post-FCS actions and identifies the challenges the Department of Defense (DOD) and the Army must address as they proceed. This testimony is based on GAO's report on the Army's Ground Force Modernization effort released on March 15, 2010. It emphasizes the December 2009 decision to begin low-rate initial production for Increment 1 of the Brigade Combat Team Modernization."

Testimony issued by the Government Accountability Office with an abstract that begins "Millions of people rely on the services of Social Security Administration (SSA) field offices. In fiscal year 2009, SSA's approximately 1,300 field offices provided service to a record 45.1 million customers. People visit field offices to apply for Social Security cards, apply for retirement and disability benefits, request replacement benefit checks, and a host of other services. Over the last several years, growing workloads have challenged field offices' ability to manage work while continuing to deliver quality customer service. The Subcommittee asked GAO to discuss our January 2009 report on SSA field office service delivery challenges. Specifically, this testimony will discuss (1) the state of SSA field office operations, and (2) the status of SSA's efforts to develop a plan to address future service delivery challenges.

It is well known in computational fluid dynamics that grid quality affects the accuracy of numerical solutions. When assessing grid quality, properties such as aspect ratio, orthogonality of coordinate surfaces, and cell volume are considered. Mesoscale atmospheric models generally use terrain-following coordinates with large aspect ratios near the surface. As high resolution numerical simulations are increasingly used to study topographically forced flows, a high degree of non-orthogonality is introduced, especially in the vicinity of steep terrain slopes. Numerical errors associated with the use of terrainfollowing coordinates can adversely effect the accuracy of the solution in steep terrain. Inaccuracies from the coordinate transformation are present in each spatially discretized term of the Navier-Stokes equations, as well as in the conservation equations for scalars. In particular, errors in the computation of horizontal pressure gradients, diffusion, and horizontal advection terms have been noted in the presence of sloping coordinate surfaces and steep topography. In this work we study the effects of these spatial discretization errors on the flow solution for three canonical cases: scalar advection over a mountain, an atmosphere at rest over a hill, and forced advection over a hill. This study is completed using the Weather Research and Forecasting (WRF) model. …

The decay heat from radioactive waste that is to be disposed in the once proposed geologic repository at Yucca Mountain (YM) will significantly influence the moisture conditions in the fractured rock near emplacement tunnels (drifts). Additionally, large-scale convective cells will form in the open-air drifts and will serve as an important mechanism for the transport of vaporized pore water from the fractured rock in the drift center to the drift end. Such convective processes would also impact drift seepage, as evaporation could reduce the build up of liquid water at the tunnel wall. Characterizing and understanding these liquid water and vapor transport processes is critical for evaluating the performance of the repository, in terms of water-induced canister corrosion and subsequent radionuclide containment. To study such processes, we previously developed and applied an enhanced version of TOUGH2 that solves for natural convection in the drift. We then used the results from this previous study as a time-dependent boundary condition in a high-resolution seepage model, allowing for a computationally efficient means for simulating these processes. The results from the seepage model show that cases with strong natural convection effects are expected to improve the performance of the repository, since smaller relative humidity …

Preliminary results support the nano-confinement of sodium alanate within the pores of a Cu{sub 3}BTC{sub 2} MOF substrate. Increased {sup 1}H and {sup 27}Al NMR T{sub 1} relaxation rates indicate a close proximity of infiltrated sodium alante to the paramagnetic Cu{sup 2+} ions on the BTC paddlewheel units. This is in support of the theory that an interaction due to the electronegative framework with the sodium alanate facilitates thermodynamically-favorable hydrogen adsorption and desorption. Further studies can elucidate the local electronic environment of the sodium ions, further supporting a charge-transfer mechanism as the driving force for thermodynamically-favorable hydrogen adsorption and desorption.

The results of a successful U.S. Department of Energy (DoE) funded two-year $2.9 MM program lead by GrafTech International Inc. (GrafTech) are reported and summarized. The program goal was to develop the next generation of high temperature proton exchange membrane (PEM) fuel cell bipolar plates for use in transportation fuel cell applications operating at temperatures up to 120 °C. The bipolar plate composite developed during the program is based on GrafTech’s GRAFCELL resin impregnated flexible graphite technology and makes use of a high temperature Huntsman Advanced Materials resin system which extends the upper use temperature of the composite to the DoE target. High temperature performance of the new composite is achieved with the added benefit of improvements in strength, modulus, and dimensional stability over the incumbent resin systems. Other physical properties, including thermal and electrical conductivity of the new composite are identical to or not adversely affected by the new resin system. Using the new bipolar plate composite system, machined plates were fabricated and tested in high temperature single-cell fuel cells operating at 120 °C for over 1100 hours by Case Western Reserve University. Final verification of performance was done on embossed full-size plates which were fabricated and glued into …

The Transuranic (TRU) Disposition Project at Savannah River Site will require numerous transfers of radioactive materials within the site boundaries for sorting and repackaging. The three DOT Type A shipping packagings planned for this work have numerous bolts for securing the lids to the body of the packagings. In an effort to reduce operator time to open and close the packages during onsite transfers, thus reducing personnel exposure and costs, an evaluation was performed to analyze the effects of reducing the number of bolts required to secure the lid to the packaging body. The evaluation showed the reduction to one-third of the original number of bolts had no effect on the packagings capability to sustain vibratory loads, shipping loads, internal pressure loads, and the loads resulting from a 4-ft drop. However, the loads caused by the 4-ft drop are difficult to estimate and the study recommended each of the packages be dropped to show the actual effects on the package closure. Even with reduced bolting, the packagings were still required to meet the 49 CFR 178.350 performance criteria for Type A packaging. This paper discusses the effects and results of the drop testing of the three packagings.

Recent thinning of glaciers over the Himalayas (sometimes referred to as the third polar region) have raised concern on future water supplies since these glaciers supply water to large river systems that support millions of people inhabiting the surrounding areas. Black carbon (BC) aerosols, released from incomplete combustion, have been increasingly implicated as causing large changes in the hydrology and radiative forcing over Asia and its deposition on snow is thought to increase snow melt. In India BC emissions from biofuel combustion is highly prevalent and compared to other regions, BC aerosol amounts are high. Here, we quantify the impact of BC aerosols on snow cover and precipitation from 1990 to 2010 over the Indian subcontinental region using two different BC emission inventories. New estimates indicate that Indian BC emissions from coal and biofuel are large and transport is expected to expand rapidly in coming years. We show that over the Himalayas, from 1990 to 2000, simulated snow/ice cover decreases by {approx}0.9% due to aerosols. The contribution of the enhanced Indian BC to this decline is {approx}36%, similar to that simulated for 2000 to 2010. Spatial patterns of modeled changes in snow cover and precipitation are similar to observations (from …

To better understand the contribution of cosmic ray muons to the CUORICINO background, ten plastic scintillator detectors were installed at the CUORICINO siteand operated during the final 3 months of the experiment. From these measurements, an upper limit of 0.0021 counts/(keV.kg.yr) (95percent c.l.) was obtained on the cosmicray induced background in the neutrinoless double beta decay region of interest. The measurements were also compared to Geant4 simulations.
