A letter report issued by the Government Accountability Office with an abstract that begins "The five Army depot maintenance activities support combat readiness by providing services to keep Army units operating worldwide. From fiscal years 2004 through 2007, the amount of new orders received to perform work increased 100 percent from $2.6 billion to $5.2 billion. The number of new orders is a factor in the amount of work the depots carry over from one fiscal year to the next. While past congressional defense committees recognize the need for carryover, the committees have raised concerns that carryover may be more than needed. GAO was asked to determine (1) the growth in reported total carryover from fiscal years 2004 through 2007 and the actions the Army is taking to reduce the carryover, (2) whether reported carryover amounts exceeded carryover ceilings for fiscal years 2006 and 2007 and adjustments made to reduce those amounts, and (3) the primary reasons for the increased carryover at the five Army depots. GAO analyzed reported carryover and related data at the five depots."

A letter report issued by the Government Accountability Office with an abstract that begins "Because marine mammals, such as whales and dolphins, often inhabit waters where commercial fishing occurs, they can become entangled in fishing gear, which may injure or kill them--this is referred to as "incidental take." The 1994 amendments to the Marine Mammal Protection Act (MMPA) require the National Marine Fisheries Service (NMFS) to establish take reduction teams for certain marine mammals to develop measures to reduce their incidental takes. GAO was asked to determine the extent to which NMFS (1) can accurately identify the marine mammal stocks--generally a population of animals of the same species located in a common area--that meet the MMPA's requirements for establishing such teams, (2) has established teams for those stocks that meet the requirements, (3) has met the MMPA's deadlines for the teams subject to them, and (4) evaluates the effectiveness of take reduction regulations. GAO reviewed the MMPA, and NMFS data on marine mammals, and take reduction team documents and obtained the views of NMFS officials, scientists, and take reduction team members."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has long been challenged in implementing key information technology (IT) management controls on its thousands of business system investments. For this and other reasons, GAO has designated DOD's business systems modernization efforts as high-risk. One of the larger business system investments is the Department of the Navy's Enterprise Resource Planning (Navy ERP) program. Initiated in 2003, the program is to standardize the Navy's business processes, such as acquisition and financial management. It is being delivered in increments, the first of which is to cost about $2.4 billion over its useful life and be fully deployed in fiscal year 2013. GAO was asked to determine whether key IT management controls are being implemented on the program. To do this, GAO analyzed, for example, requirements management, economic justification, earned value management, and risk management."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) established a goal to achieve total asset visibility over 30 years ago. This initiative aims to provide timely, accurate information on the location, movement, status, and identity of equipment and supplies. To date, the effort has been unsuccessful. GAO was requested to determine (1) the implementation status of the Air Force's business system initiatives to achieve total asset visibility, and whether the Air Force has implemented related best practices, and (2) whether the Air Force's business transformation efforts to achieve total asset visibility are aligned within the Air Force and with DOD's broader business transformation priorities. GAO interviewed Air Force officials and reviewed Air Force documentation to obtain an understanding of the Air Force's system initiatives and strategy for achieving total asset visibility and to identify areas for improvement."

A letter report issued by the Government Accountability Office with an abstract that begins "The International Marriage Broker Regulation Act of 2005 (IMBRA) was enacted to address issues of domestic violence and abuse against noncitizens (beneficiaries) married or engaged to U.S. citizens (petitioners) who have petitioned for them to immigrate to the U.S., including those who met through an international marriage broker (IMB). IMBRA mandated that GAO study the act's impact on the visa process for noncitizen spouses and fiance(e)s. This report addresses the extent to which the U.S. Citizenship and Immigration Services (USCIS), a component of the Department of Homeland Security (DHS); the Department of State (DOS); and the Department of Justice (DOJ) have implemented IMBRA, and the extent to which USCIS and DOS have collected and maintained data for this GAO report as required by IMBRA. To address these objectives, GAO reviewed the act and related legislation, analyzed IMBRA implementation guidance and available data on applications filed, and interviewed officials at USCIS, DOS, and DOJ."

A letter report issued by the Government Accountability Office with an abstract that begins "Health centers funded through grants under the Health Center Program--managed by the Health Resources and Services Administration (HRSA), an agency in the U.S. Department of Health and Human Services (HHS)--provide comprehensive primary care services for the medically underserved. HRSA provides funding for training and technical assistance (TA) cooperative agreement recipients to assist grant applicants. GAO was asked to examine (1) to what extent medically underserved areas (MUA) lacked health center sites in 2006 and 2007 and (2) HRSA's oversight of training and TA cooperative agreement recipients' assistance to grant applicants and its provision of written feedback provided to unsuccessful applicants. To do this, GAO obtained and analyzed HRSA data, grant applications, and the written feedback provided to unsuccessful grant applicants and interviewed HRSA officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, several mining tragedies led the Congress to pass the Mine Improvement and New Emergency Response Act of 2006 (MINER Act). The law required underground coal mine operators to develop emergency response plans that contain several components designed to improve accident preparedness and response, including providing a refuge of air to miners trapped underground after an accident and wireless communications systems. The Mine Safety and Health Administration (MSHA) is responsible for approving the plans and ensuring their implementation. GAO examined (1) the effectiveness of the approval process, (2) the status of implementation of the plans, and (3) MSHA's efforts to enforce and oversee implementation. To address these questions, GAO reviewed a nonprobability sample of emergency response plans, analyzed MSHA data, and interviewed MSHA officials and members of the mining community."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States is at a critical juncture in addressing the demands on its transportation system, including highway infrastructure. State and local governments are looking for alternatives, including increased private sector participation. GAO was asked to review (1) the benefits, costs, and trade-offs of public-private partnerships; (2) how public officials have identified and acted to protect the public interest in these arrangements; and (3) the federal role in public-private partnerships and potential changes in this role. GAO reviewed federal legislation, interviewed federal, state, and other officials, and reviewed the experience of Australia, Canada, and Spain. GAO's work focused on highway-related public-private partnerships and did not review all forms of public-private partnerships."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has designated the Department of Defense's (DOD) multi-billion dollar business systems modernization efforts as high risk, in part because key information technology (IT) management controls have not been implemented on key investments, such as the Navy Cash program. Initiated in 2001, Navy Cash is a joint Department of the Navy (DON) and Department of the Treasury Financial Management Service (FMS) program to create a cashless environment on ships using smart card technology, and is estimated to cost about $320 million to fully deploy. As requested, GAO analyzed whether DON is effectively implementing IT management controls on the program, including architectural alignment, economic justification, requirements development and management, risk management, security management, and system quality measurement against relevant guidance."

A letter report issued by the Government Accountability Office with an abstract that begins "Pressure on state and local governments to deliver highway projects and services, and limits on the ability of state departments of transportation (state DOT) to increase staff levels have led those departments to contract out a variety of highway activities to the private sector. As requested, this report addresses (1) recent trends in the contracting of state highway activities, (2) factors that influence state highway departments' contracting decisions, (3) how state highway departments ensure the protection of the public interest when work is contracted out, and (4) the Federal Highway Administrations' (FHWA) role in ensuring that states protect the public interest. To complete this work, GAO reviewed federal guidelines, state auditor reports, and other relevant literature; conducted a 50-state survey; and interviewed officials from 10 selected state highway departments, industry officials, and FHWA officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the federal government spent $13 billion--14 percent of its research and development (R&D) expenditures--to enable 38 federally funded R&D centers (FFRDCs) to meet special research needs. FFRDCs--including laboratories, studies and analyses centers, and systems engineering centers--conduct research in military space programs, nanotechnology, microelectronics, nuclear warfare, and biodefense countermeasures, among other areas. GAO was asked to identify (1) how federal agencies contract with organizations operating FFRDCs and (2) agency oversight processes used to ensure that FFRDCs are well-managed. GAO's work is based on a review of documents and interviews with officials from eight FFRDCs sponsored by the departments of Defense (DOD), Energy (DOE), Health and Human Services (HHS), and Homeland Security (DHS). What GAO Recommends"

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service (IRS) relies extensively on computerized systems to carry out its demanding responsibilities to collect taxes (about $2.7 trillion in fiscal year 2007), process tax returns, and enforce the nation's tax laws. Effective information security controls are essential to ensuring that financial and taxpayer information is adequately protected from inadvertent or deliberate misuse, fraudulent use, improper disclosure, or destruction. As part of its audit of IRS's fiscal years 2007 and 2006 financial statements, GAO assessed (1) IRS's actions to correct previously reported information security weaknesses and (2) whether controls were effective in ensuring the confidentiality, integrity, and availability of financial and sensitive taxpayer information. To do this, GAO examined IRS information security policies and procedures, guidance, security plans, reports, and other documents; tested controls over key financial applications at three IRS data centers; and interviewed key security representatives and management officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Afghan government, the United States, and other donors consider road reconstruction a top development priority for Afghanistan. Almost 20 percent of the U.S. Agency for International Development's (USAID) $5.9 billion in assistance to Afghanistan has been for roads. The Department of Defense (Defense) has committed about $560 million for roads, of which Commander's Emergency Response Program (CERP) funds account for over half. GAO examined (1) the status of road reconstruction and challenges affecting project implementation, (2) U.S. agencies' efforts to evaluate the impact of road projects, and (3) efforts to develop a sustainable road maintenance program. GAO reviewed U.S. and Afghan governments' planning, evaluation, and funding documents and interviewed relevant stakeholders in Afghanistan."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) is responsible for coordinating the federal government's homeland security communications with all levels of government. In support of this mission, DHS implemented, and has been enhancing, the Homeland Security Information Network (HSIN). It also has proposed a follow-on system, called Next Generation HSIN (HSIN Next Gen). GAO was asked to determine whether (1) DHS has stopped further improvements on HSIN and if so, the department's rationale for doing so and plans for acquiring its proposed follow-on system HSIN Next Gen and (2) the department is effectively managing the HSIN Next Gen acquisition. To accomplish this, GAO analyzed documentation, interviewed officials, and compared acquisition management processes and practices defined in industry best practices with those planned and underway by DHS."

A letter report issued by the Government Accountability Office with an abstract that begins "Interagency contracting--using another agency's contracts or contracting services--can provide agencies with opportunities to streamline the procurement process and achieve savings. However, GAO designated the management of interagency contracting a high-risk area in 2005 due, in part, to a lack of reliable data on its use and of clarity regarding contract management responsibilities. In 2002, the Department of State (State) issued the State First policy, requiring domestic bureaus to obtain approval from State acquisition officials before paying other agencies for contract support services. Under the Comptroller General's authority to conduct evaluations on his own initiative, GAO evaluated State's 1) insight into its use of interagency contracts, 2) policies on deciding when to use assisted interagency contracts, and 3) ability to ensure oversight. GAO's work included reviewing regulations, analyzing interagency contracting data, and conducting 10 case studies of direct and assisted interagency contracts that represented a range of State bureaus and servicing agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration (TSA) uses undercover, or covert, testing to approximate techniques that terrorists may use to identify vulnerabilities in and measure the performance of airport security systems. During these tests, undercover inspectors attempt to pass threat objects through passenger and baggage screening systems, and access secure airport areas. In response to a congressional request, GAO examined (1) TSA's strategy for conducting covert testing of the transportation system and the extent to which the agency has designed and implemented its covert tests to achieve identified goals; and (2) the results of TSA's national aviation covert tests conducted from September 2002 to June 2007, and the extent to which TSA uses the results of these tests to mitigate security vulnerabilities. To conduct this work, GAO analyzed covert testing documents and data and interviewed TSA and transportation industry officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Traumatic brain injury (TBI) has emerged as a leading injury among servicemembers serving in the Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) combat theaters. The widespread use of improvised explosive devices, such as roadside bombs, in these combat theaters increases the likelihood that servicemembers will be exposed to incidents that can cause a TBI. TBIs can vary from mild to severe, and in general, mild TBI can be difficult to identify. Because mild TBI can have lasting effects if not identified and treated, concerns have been raised about how the Department of Veterans Affairs (VA) identifies and treats OEF/OIF veterans with a mild TBI. In this report GAO describes VA's (1) efforts to screen OEF/OIF veterans for mild TBI, (2) steps taken so that those OEF/OIF veterans at risk for mild TBI are evaluated and treated, and (3) challenges in screening and evaluating OEF/OIF veterans for mild TBI. GAO reviewed VA's policies, interviewed VA officials and TBI experts, and reviewed nine VA medical facilities' efforts to implement TBI screening and evaluation processes."

The Supplemental Security Income (SSI) program, Title XVI of the Social Security Act, was enacted in 1972 and implemented in 1974 to assure a minimum cash income to all aged, blind, or disabled persons. SSI is provided to eligible aged or disabled individuals or couples who have limited income and resources.

Nationwide, the demand for electricity due to population and industrial growth is on the rise. However, climate change and air quality issues raise serious questions about the wisdom of addressing these shortages through the construction of additional fossil fueled power plants. In 1997, the President's Committee of Advisors on Science and Technology Energy Research and Development Panel determined that restoring a viable nuclear energy option was essential and that the DOE should implement a R&D effort to address principal obstacles to achieving this option. This work has addressed the need for improved thermal/fluid analysis capabilities, through the use of computational fluid dynamics, which are necessary to support the design of generation IV gas-cooled and supercritical water reactors.

The Fast Ignition (FI) concept for Inertial Confinement Fusion (ICF) has the potential to provide a significant advance in the technical attractiveness of Inertial Fusion Energy (IFE) reactors. FI differs from conventional 'central hot spot' (CHS) target ignition by using one driver (laser, heavy ion beam or Z-pinch) to create a dense fuel and a separate ultra-short, ultra-intense laser beam to ignite the dense core. FI targets can burn with {approx} 3X lower density fuel than CHS targets, resulting in (all other things being equal) lower required compression energy, relaxed drive symmetry, relaxed target smoothness tolerances, and, importantly, higher gain. The short, intense ignition pulse that drives this process interacts with extremely high energy density plasmas; the physics that controls this interaction is only now becoming accessible in the lab, and is still not well understood. The attraction of obtaining higher gains in smaller facilities has led to a worldwide explosion of effort in the studies of FI. In particular, two new US facilities to be completed in 2009/2010, OMEGA/OMEGA EP and NIF-ARC (as well as others overseas) will include FI investigations as part of their program. These new facilities will be able to approach FI conditions much more closely …

It has been successfully demonstrated in this program that a zirconia multilayer structure with rhodium-based porous electrodes performs well as an amperometric NOx sensor. The sensitivity of the sensor bodies operating at 650 to 700 C is large, with demonstrated current outputs of 14 mA at 500 ppm NOx from sensors with 30 layers. The sensor bodies are small (4.5 x 4.2 x 3.1 mm), rugged, and inexpensive. It is projected the sensor bodies will cost $5 - $10 in production. This program has built on another successful development program for an oxygen sensor based on the same principles and sponsored by DOE. This oxygen sensor is not sensitive to NOx. A significant technical hurdle has been identified and solved. It was found that the 100% Rh electrodes oxidize rapidly at the preferred operating temperatures of 650 - 700 C, and this oxidation is accompanied by a volume change which delaminates the sensors. The problem was solved by using alloys of Rh and Pt. It was found that a 10%/90% Rh/Pt alloy dropped the oxidation rate of the electrodes by orders of magnitude without degrading the NOx sensitivity of the sensors, allowing long-term stable operation at the preferred operating temperatures. …

The Siemens Advanced Quantra Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer was evaluated as an alternative instrument to large double focusing mass spectrometers for gas analysis. High resolution mass spectrometers capable of resolving the common mass isomers of the hydrogen isotopes are used to provide data for accurate loading of reservoirs and to monitor separation of tritium, deuterium, and helium. Conventional double focusing magnetic sector instruments have a resolution that is limited to about 5000. The Siemens FTICR instrument achieves resolution beyond 400,000 and could possibly resolve the tritium ion from the helium-3 ion, which differ by the weight of an electron, 0.00549 amu. Working with Y-12 and LANL, SRNL requested Siemens to modify their commercial Quantra system for low mass analysis. To achieve the required performance, Siemens had to increase the available waveform operating frequency from 5 MHz to 40 MHz and completely redesign the control electronics and software. However, they were able to use the previous ion trap, magnet, passive pump, and piezo-electric pulsed inlet valve design. NNSA invested $1M in this project and acquired four systems, two for Y-12 and one each for SRNL and LANL. Siemens claimed a $10M investment in the Quantra systems. The …

This research and development program was designed to improve nondestructive evaluation of large mechanical objects by providing both fast and thermal neutron sources for radiography. Neutron radiography permits inspection inside objects that x-rays cannot penetrate and permits imaging of corrosion and cracks in low-density materials. Discovering of fatigue cracks and corrosion in piping without the necessity of insulation removal is possible. Neutron radiography sources can provide for the nondestructive testing interests of commercial and military aircraft, public utilities and petrochemical organizations. Three neutron prototype neutron generators were designed and fabricated based on original research done at the Lawrence Berkeley National Laboratory (LBNL). The research and development of these generators was successfully continued by LBNL and Adelphi Technology Inc. under this STTR. The original design goals of high neutron yield and generator robustness have been achieved, using new technology developed under this grant. In one prototype generator, the fast neutron yield and brightness was roughly 10 times larger than previously marketed neutron generators using the same deuterium-deuterium reaction. In another generator, we integrate a moderator with a fast neutron source, resulting in a high brightness thermal neutron generator. The moderator acts as both conventional moderator and mechanical and electrical support structure …
