Testimony issued by the Government Accountability Office with an abstract that begins "The budget authority GAO is requesting for fiscal year 2009--$545.5 million--represents a prudent request of 7.5 percent to support the Congress as it confronts a growing array of difficult challenges. GAO will continue to reward the confidence you place in us by providing a strong return on this investment. In fiscal year 2007 for example, in addition to delivering hundreds of reports and briefings to aid congressional oversight and decisionmaking, our work yielded: financial benefits, such as increased collection of delinquent taxes and civil fines, totaling $45.9 billion--a return of $94 for every dollar invested in GAO; over 1,300 other improvements in government operations spanning the full spectrum of national issues, ranging from helping Congress create a center to better locate children after disasters to strengthening computer security over sensitive government records and assets to encouraging more transparency over nursing home fire safety to strengthening screening procedures for VA health care practitioners; and expert testimony at 276 congressional hearings to help Congress address a variety of issues of broad national concern, such as the conflict in Iraq and efforts to ensure drug and food safety."

Testimony issued by the Government Accountability Office with an abstract that begins "Unauthorized individuals, companies, terrorist organizations, and other countries continue their attempts to obtain sensitive items related to the defense of the United States. The Internet is one place that defense-related items can be purchased, raising the possibility that some sensitive items are available to those who can afford them. In addition to the risk that sensitive defense-related items could be used to directly harm U.S. service members or allies on the battlefield, these items could be disassembled and analyzed (i.e., reverse engineered) to develop countermeasures or equivalent technology. Given the risks posed by the sale of sensitive defense-related items to the public, and the Internet's international reach and high volume of commerce, the Subcommittee asked GAO to conduct undercover testing to determine whether the general public can easily purchase these items on the Internet, including on the Web sites eBay and Craigslist. To perform this work, GAO investigators used undercover identities to pose as members of the general public, meaning that they conducted their work with names, credit cards, and contact information that could not be traced to GAO. Investigators interviewed sellers where possible and referred cases to …

Testimony issued by the Government Accountability Office with an abstract that begins "The high pace of overseas operations is taking a heavy toll on Army equipment. Harsh combat and environmental conditions over sustained periods of time have exacerbated equipment repair, replacement, and recapitalization problems. The Army has also taken steps to restructure its forces before implementing its longer term transformation to the Future Combat System. To support ongoing operations and prepare for the future, the Army has embarked on four key initiatives: (1) restructuring from a division-based force to a modular brigade-based force, (2) expanding the Army by adding about 74,000 people and creating new units, (3) repairing, replacing, and recapitalizing new equipment through its reset program, and (4) replacing equipment borrowed from its pre-positioned equipment sets around the world. Since 2004, Congress has provided billions of dollars to support the Army's equipping needs. GAO has issued many reports on the Army's efforts to equip modular units, expand the Army, reset equipment, and manage and replace prepositioned equipment. This statement, which draws largely on these reports, will address (1) the equipment-related cost of these initiatives, and (2) the management challenges facing the Army and the actions needed to improve its …

Testimony issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) program--which comprises 14 integrated weapon systems and an advanced information network--is the centerpiece of the Army's effort to transition to a lighter, more agile, and more capable combat force. The substantial technical challenges, the Army's acquisition strategy, and the cost of the program are among the reasons why the program is recognized as needing special oversight and review. This testimony is based on GAO's two March 2008 reports on FCS and addresses (1) how the definition, development, and demonstration of FCS capabilities are proceeding, particularly in light of the go/no-go decision scheduled for 2009; (2) the Army's plans for making production commitments for FCS and any risks related to the completion of development; and (3) the estimated costs for developing and producing FCS."

Spark plasma sintering (SPS) is a remarkable method for synthesizing and consolidating a large variety of both novel and traditional materials. The process typically uses moderate uni-axial pressures (<100 MPa) in conjunction with a pulsing on-off DC current during operation. There are a number of mechanisms proposed to account for the enhanced sintering abilities of the SPS process. Of these mechanisms, the one most commonly put forth and the one that draws the most controversy involves the presence of momentary plasma generated between particles. This study employees three separate experimental methods in an attempt to determine the presence or absence of plasma during SPS. The methods employed include: in-situ atomic emission spectroscopy, direct visual observation and ultra-fast in-situ voltage measurements. It was found using these experimental techniques that no plasma is present during the SPS process. This result was confirmed using several different powders across a wide spectrum of SPS conditions.

A wide spectrum of laboratory owners, ranging from universities to federal agencies, have explicit goals for energy efficiency in their facilities. For example, the Energy Policy Act of 2005 (EPACT 2005) requires all new federal buildings to exceed ASHRAE 90.1-2004 [1] by at least 30%. A new laboratory is much more likely to meet energy efficiency goals if quantitative metrics and targets are specified in programming documents and tracked during the course of the delivery process. If not, any additional capital costs or design time associated with attaining higher efficiencies can be difficult to justify. This article describes key energy efficiency metrics and benchmarks for laboratories, which have been developed and applied to several laboratory buildings--both for design and operation. In addition to traditional whole building energy use metrics (e.g. BTU/ft{sup 2}.yr, kWh/m{sup 2}.yr), the article describes HVAC system metrics (e.g. ventilation W/cfm, W/L.s{sup -1}), which can be used to identify the presence or absence of energy features and opportunities during design and operation.

This study focuses on the fate of exported organic carbon in the twilight zone at two contrasting environments in the North Pacific: the oligotrophic ALOHA site (22 degrees 45 minutes N 158 degrees W; Hawaii; studied during June-July 2004) and the mesotrophic Subarctic Pacific K2 site (47 degrees N, 161 degrees W; studied during July-August 2005). Earlier work has shown that non-lithogenic, excess particulate Ba (Ba{sub xs}) in the mesopelagic water column is a potential proxy of organic carbon remineralization. In general Ba{sub xs} contents were significantly larger at K2 than at ALOHA. At ALOHA the Ba{sub xs} profiles from repeated sampling (5 casts) showed remarkable consistency over a period of three weeks, suggesting that the system was close to being at steady state. In contrast, more variability was observed at K2 (6 casts sampled) reflecting the more dynamic physical and biological conditions prevailing in this environment. While for both sites Ba{sub xs} concentrations increased with depth, at K2 a clear maximum was present between the base of the mixed layer at around 50m and 500m, reflecting production and release of Ba{sub xs}. Larger mesopelagic Ba{sub xs} contents and larger bacterial production in the twilight zone at the K2 site …

The "Minor Actinide Doppler Coefficient Measurement Assessment" was a Department of Energy (DOE) U-NERI funded project intended to assess the viability of using either the FLATTOP or the COMET critical assembly to measure high temperature Doppler coefficients. The goal of the project was to calculate using the MCNP5 code the gram amounts of Np-237, Pu-238, Pu-239, Pu-241, AM-241, AM-242m, Am-243, and CM-244 needed to produce a 1E-5 in reactivity for a change in operating temperature 800C to 1000C. After determining the viability of using the assemblies and calculating the amounts of each actinide an experiment will be designed to verify the calculated results. The calculations and any doncuted experiments are designed to support the Advanced Fuel Cycle Initiative in conducting safety analysis of advanced fast reactor or acceoerator-driven transmutation systems with fuel containing high minor actinide content.

Carbon dioxide is the major “greenhouse” gas responsible for global warming. Southeastern pine forests appear to be among the largest terrestrial sinks of carbon dioxide in the US. This collaborative study specifically addressed the isotopic signatures of the large fluxes of carbon taken up by photosynthesis and given off by respiration in this ecosystem. By measuring these isotopic signatures at the ecosystem level, we have provided data that will help to more accurately quantify the magnitude of carbon fluxes on the regional scale and how these fluxes vary in response to climatic parameters such as rainfall and air temperature. The focus of the MBL subcontract was to evaluate how processes operating at the physiological and ecosystem scales affects the resultant isotopic signature of plant waxes that are emitted as aerosols into the convective boundary layer. These wax aerosols provide a large-spatial scale integrative signal of isotopic discrimination of atmospheric carbon dioxide by terrestrial photosynthesis (Conte and Weber 2002). The ecosystem studies have greatly expanded of knowledge of wax biosynthetic controls on their isootpic signature The wax aerosol data products produced under this grant are directly applicable as input for global carbon modeling studies that use variations in the concentration and …

In the first two years of this research we focused on the development of a DNA microarray for transcriptional studies in the photosynthetic organism Synechocystis and the elucidation of the metabolic pathway for biopolymer synthesis in this organism. In addition we also advanced the molecular biological tools for metabolic engineering of biopolymer synthesis in Synechocystis and initiated a series of physiological studies for the elucidation of the carbon fixing pathways and basic central carbon metabolism of these organisms. During the last two-year period we focused our attention on the continuation and completion of the last task, namely, the development of tools for basic investigations of the physiology of these cells through, primarily, the determination of their metabolic fluxes. The reason for this decision lies in the importance of fluxes as key indicators of physiology and the high level of information content they carry in terms of identifying rate limiting steps in a metabolic pathway. While flux determination is a well-advanced subject for heterotrophic organisms, for the case of autotrophic bacteria, like Synechocystis, some special challenges had to be overcome. These challenges stem mostly from the fact that if one uses {sup 13}C labeled CO{sub 2} for flux determination, the {sup …

The Employee Retirement Income Security Act of 1974 (ERISA) provides a comprehensive federal scheme for the regulation of employee pension and welfare benefit plans offered by employers. ERISA contains various provisions intended to protect the rights of plan participants and beneficiaries in employee benefit plans. These protections include requirements relating to reporting and disclosure, participation, vesting, and benefit accrual, as well as plan funding. ERISA also regulates the responsibilities of plan fiduciaries and other issues regarding plan administration. ERISA contains various standards that a plan must meet in order to receive favorable tax treatment, and also governs plan termination. This report provides background on the pension laws prior to ERISA, discusses various types of employee benefit plans governed by ERISA, provides an overview of ERISA’s requirements, and includes a glossary of commonly used terms.
