A letter report issued by the Government Accountability Office with an abstract that begins "Created in 1923, the American Battle Monuments Commission (the Commission) operates and maintains 24 American military cemeteries on foreign soil; 25 federal memorials, monuments, and markers; and 7 nonfederal memorials. For fiscal year 2010, the Commission incurred program costs of $69.6 million to maintain its cemeteries and federal memorials. In accordance with 36 U.S.C. 2103, GAO is responsible for conducting audits of the agencywide financial statements of the Commission. GAO audited the financial statements of the Commission for the fiscal years ended September 30, 2010, and 2009. The audits were done to determine whether, in all material respects, (1) the Commission's financial statements were presented fairly and (2) Commission management maintained effective internal control over financial reporting. GAO also tested Commission management's compliance with selected laws and regulations."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of the Interior (Interior) is responsible for managing much of the nation's vast natural resources. Its agencies implement an array of programs intended to protect these resources for future generations while also allowing certain uses of them, such as recreation and oil and gas development. In some cases, Interior is authorized to collect royalties and fees for these uses. Over the years, GAO has reported on management challenges at Interior, which are largely characterized by the struggle to balance the demand for greater use of its resources with the need to conserve and protect them. Furthermore, given the government's long-term fiscal challenges, Interior faces difficult choices in balancing its responsibilities. This testimony highlights some of the major management challenges facing Interior today. It is based on prior GAO reports."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the challenges that the Department of Defense (DOD) faces in fulfilling urgent operational needs identified by our warfighters. Over the course of the wars in Iraq and Afghanistan, U.S. forces have encountered changing adversarial tactics, techniques, and procedures, which challenged DOD to quickly develop and provide new equipment and new capabilities to address evolving threats. Further, U.S. troops faced shortages of critical items, including body armor, tires, and batteries. DOD's goal is to provide solutions as quickly as possible to meet urgent warfighter needs to prevent mission failure or loss of life. To meet its urgent needs, DOD had to look beyond traditional acquisition procedures, expand the use of existing processes, and develop new processes and entities designed to be as responsive as possible to urgent warfighter requests. In addition to requests for equipment from DOD's existing stocks, warfighters have requested new capabilities, such as: technology to counter improvised explosive devices (IED); technology related to intelligence, surveillance, and reconnaissance (ISR) to provide increased situational awareness; and equipment related to command and control to enhance operations on the battlefield. In meeting urgent needs, it is important …

A letter report issued by the Government Accountability Office with an abstract that begins "Since the early 1990s, Congress has supplemented the Department of Education's (Education) Impact Aid program by providing funds for the Department of Defense's (DOD) Impact Aid program to compensate school districts with a high number of military dependent students. The National Defense Authorization Act for Fiscal Year 2010 required GAO to review the use of these funds. GAO reviewed (1) what is known about the utilization and effectiveness of DOD Impact Aid funds, (2) the challenges faced by school districts in serving military dependent students, and (3) how DOD and Education have collaborated on their assistance. To address these issues, GAO conducted a Web-based survey of all 154 school districts that received DOD Impact Aid in any year from 2001 to 2009, with a response rate of 77 percent. GAO also interviewed officials from DOD and Education and seven school districts in five states, ranging in school district size, location, and percentage of military dependent students. The findings from these visits cannot be projected nationwide, but illustrate valuable perspectives."

A letter report issued by the Government Accountability Office with an abstract that begins "Forces in Iraq and Afghanistan have faced significant risks of mission failure and loss of life due to rapidly changing enemy threats. In response, the Department of Defense (DOD) established urgent operational needs processes to rapidly develop, modify, and field new capabilities, such as intelligence, surveillance and reconnaissance (ISR) technology, and counter-improvised explosive devices (IED) systems. However, GAO, the Defense Science Board, and others have raised concerns about the effectiveness, efficiency, and oversight of DOD's various urgent needs processes. GAO conducted this review to determine (1) what various entities exist within DOD for responding to urgent operational needs, and the extent to which there is fragmentation, overlap, or duplication; (2) the extent to which DOD has a comprehensive approach for managing and overseeing its urgent needs activities; and (3) the extent to which DOD has evaluated the potential for consolidations. To conduct this review, GAO examined DOD's urgent needs processes and collected and analyzed data from urgent needs entities."

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2009, the Department of Defense's (DOD) Military Tuition Assistance (TA) Program provided $517 million in tuition assistance to approximately 377,000 service members. GAO was asked to report on (1) DOD's oversight of schools receiving TA funds, and (2) the extent to which DOD coordinates with accrediting agencies and the U.S. Department of Education (Education) in its oversight activities. GAO conducted site visits to selected military education centers and interviewed officials from DOD, its contractors, Education, accrediting agencies and their association, and postsecondary institutions."

This report discusses the current state of Serbia. It is seeking to integrate into the European Union (EU), but its progress has been hindered by a failure to arrest remaining indicted war criminals, and by tensions with the United States and many EU countries over the independence of Serbia's Kosovo province. This report discusses these issues in addition to issues regarding U.S.-Serbia relations.

This report provides an overview of Iraq's political transition from the dictatorship of Saddam Hussein to a plural polity that encompasses varying sects and ideological and political factions. This report also addresses ongoing governmental instabilities and their causes, as well as U.S. concerns about possible Iranian influence in Iraq as U.S. forces depart the country.

This report focuses on the United States' relationship with Iran and how the Obama Administration is handling prior administration's economic sanctions against Iran. The Obama Administration's policy approach toward Iran has contrasted with the Bush Administration's by attempting to couple the imposition of sanctions to an active and direct U.S. effort to negotiate with Iran on the nuclear issue. That approach was not initially altered because of the Iranian dispute over its June 12, 2009, elections. However, with subsequent negotiations yielding no firm Iranian agreement to compromise, since early 2010 the Administration has focused on achieving the imposition of additional U.N., U.S., and allied country sanctions whose cumulative effect would be to compel it to accept a nuclear bargain.

This report describes the relationship between the United States and the Sultanate of Oman, especially with respect to Oman's support of U.S. efforts toward peace in the Middle East, the U.S. free trade agreement with Oman, and Oman's relatively close relations with Iran, the last of which seems incongruous with the other positive aspects of Oman's relationship with the U.S.

This report discusses the current political and economic conditions in the country of Panama, which has made notable political and economic progress since the 1989 U.S. military intervention that ousted the regime of General Manuel Noriega from power. The United States has close relations with Panama, stemming in large part from the extensive linkages developed when the canal was under U.S. control. This report describes the U.S.-Panama relationship at length, including trade relations.

This report presents a summary of trade negotiations and the proposed U.S.-Panama free trade agreement (FTA). The proposed U.S.-Panama FTA is a comprehensive agreement. Some 88% of U.S. commercial and industrial exports would become duty-free upon implementation, with remaining tariffs phased out over a 10-year period.

A parametric study was conducted using EnergyPlus version 6.0 to investigate humidity issues on a typical mid-1990s reference home, a 2006 International Energy Conservation Code home, and a high-performance home in a hot-humid climate. The impacts of various dehumidification equipment and controls are analyzed on the high performance home. The study examined the combined effects of infiltration and mechanical ventilation with balanced and unbalanced mechanical ventilation systems. Indoor relative humidity excursions were examined; specifically, the number of excursions, average excursion length, and maximum excursion length. Space relative humidity, thermal comfort, and whole-house source energy consumption were analyzed for indoor relative humidity set points of 50%, 55%, and 60%. The study showed and explained why similar trends of high humidity were observed in all three homes regardless of energy efficiency, and why humidity problems are not necessarily unique in high-performance homes. Thermal comfort analysis indicated that occupants are unlikely to notice indoor humidity problems. The study confirmed that supplemental dehumidification should be provided to maintain space relative humidity below 60% in a hot-humid climate.

This SAND report documents a late start LDRD designed to determine the possible aging effects of a quartz resonator gold adhesion layer. Sandia uses quartz resonators for applications. These applications require a very stable frequency source with excellent aging (low drift) characteristics. These parts are manufactured by one of our qualified vendors outside Sandia Laboratories, Statek Corp. Over the years we, Sandia and the vendor, have seen aging variations that have not been completely explained by the typical mechanisms known in the industry. One theory was that the resonator metallization may be contributing to the resonator aging. This LDRD would allow us to test and analyze a group of resonators with known differentiating metallization and via accelerated aging determine if a chrome adhesion layer used to accept the final gold plating may contribute to poor aging. We worked with our main vendor to design and manufacture a set of quartz resonators with a wide range of metallization thickness ratios between the chrome and gold that will allow us determine the cause of this aging and which plating thickness ratios provide the best aging performance while not degrading other key characteristics.

This is the final report for the Presidential Early Career Award for Science and Engineering - PECASE (LDRD projects 93369 and 118841) awarded to Professor Yunfeng Lu (Tulane University and University of California-Los Angeles). During the last decade, mesoporous materials with tunable periodic pores have been synthesized using surfactant liquid crystalline as templates, opening a new avenue for a wide spectrum of applications. However, the applications are somewhat limited by the unfavorabe pore orientation of these materials. Although substantial effort has been devoted to align the pore channels, fabrication of mesoporous materials with perpendicular pore channels remains challenging. This project focused on fabrication of mesoporous materials with perpendicularly aligned pore channels. We demonstrated structures for use in water purification, separation, sensors, templated synthesis, microelectronics, optics, controlled release, and highly selective catalysts.

Oak Ridge National Laboratory (ORNL) offers the scientific community unique access to two types of world-class neutron sources at a single site - the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR). The 85-MW HFIR provides one of the highest steady-state neutron fluxes of any research reactor in the world, and the SNS is one of the world's most intense pulsed neutron beams. Management of these two resources is the responsibility of the Neutron Sciences Directorate (NScD). NScD commissioned this survey research to develop baseline information regarding awareness of and perceptions about neutron science. Specific areas of investigative interest include the following: (1) awareness levels among those in the scientific community about the two neutron sources that ORNL offers; (2) the level of understanding members of various scientific communities have regarding benefits that neutron scattering techniques offer; and (3) any perceptions that negatively impact utilization of the facilities. NScD leadership identified users of two light sources in North America - the Advanced Photon Source (APS) at Argonne National Laboratory and the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory - as key publics. Given the type of research in which these scientists engage, they would quite …

An air-ingress accident followed by a pipe break is considered as a critical event for a very high temperature gas-cooled reactor (VHTR). Following helium depressurization, it is anticipated that unless countermeasures are taken, air will enter the core through the break leading to oxidation of the in-core graphite structure. Thus, without mitigation features, this accident might lead to severe exothermic chemical reactions of graphite and oxygen. Under extreme circumstances, a loss of core structural integrity may occur along with excessive release of radiological inventory. Idaho National Laboratory under the auspices of the U.S. Department of Energy is performing research and development (R&D) that focuses on key phenomena important during challenging scenarios that may occur in the VHTR. Phenomena Identification and Ranking Table (PIRT) studies to date have identified the air ingress event, following on the heels of a VHTR depressurization, as very important (Oh et al. 2006, Schultz et al. 2006). Consequently, the development of advanced air ingress-related models and verification and validation (V&V) requirements are part of the experimental validation plan. This paper discusses about various air-ingress mitigation concepts applicable for the VHTRs. The study begins with identifying important factors (or phenomena) associated with the air-ingress accident by using …

Net-zero energy buildings generate as much energy as they consume and are significant in the sustainable future of building design and construction. The role of daylighting (and its simulation) in the design process becomes critical. In this paper we present the process the National Renewable Energy Laboratory embarked on in the procurement, design, and construction of its newest building, the Research Support Facility (RSF) - particularly the roles of daylighting, electric lighting, and simulation. With a rapid construction schedule, the procurement, design, and construction had to be tightly integrated; with low energy use. We outline the process and measures required to manage a building design that could expect to operate at an efficiency previously unheard of for a building of this type, size, and density. Rigorous simulation of the daylighting and the electric lighting control response was a given, but the oft-ignored disconnect between lighting simulation and whole-building energy use simulation had to be addressed. The RSF project will be thoroughly evaluated for its performance for one year; preliminary data from the postoccupancy monitoring efforts will also be presented with an eye toward the current efficacy of building energy and lighting simulation.

The conceptual design of a new dipole corrector magnet has been thoroughly studied. The planned Long-Baseline Neutrino Experiment (LBNE) beam line will require correctors capable of greater range and linearity than existing correctors, so a new design is proposed based on the horizontal trim dipole correctors built for the Main Injector synchrotron at Fermilab. The gap, pole shape, length, and number of conductor turns remain the same. To allow operation over a wider range of excitations without overheating, the conductor size is increased, and to maintain better linearity, the back leg thickness is increased. The magnetic simulation was done using ANSYS to optimize the shape and the size of the yoke. The thermal performance was also modeled and analyzed.
