Drug Control: U.S. Counternarcotics Cooperation with Venezuela Has Declined
A letter report issued by the Government Accountability Office with an abstract that begins "Hundreds of metric tons of cocaine flow annually from South America toward the United States, threatening the security and well-being of U.S. citizens. Since 2000, the United States has provided about $8 billion to countries in the region to disrupt drug trafficking. Most of this assistance went to Colombia to reduce illicit drug production and improve security. In March 2009, the Department of State reported that Venezuela had become a major transit route for cocaine out of Colombia, with a more than fourfold increase in cocaine flow between 2004 and 2007. We determined (1) what is known about cocaine trafficking through Venezuela, (2) what is known about Venezuelan support for Colombian illegal armed groups, and (3) the status of U.S and Venezuelan counternarcotics cooperation since 2002. To address these objectives, we reviewed U.S. counternarcotics reports, assessments, and other documents regarding illicit drugs transiting Venezuela. We also traveled to Venezuela and Colombia to discuss these matters with U.S. and foreign government officials."

Defense Exports: Foreign Military Sales Program Needs Better Controls for Exported Items and Information for Oversight
A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, the Foreign Military Sales (FMS) program sold over $36 billion dollars in defense articles and services to foreign governments. The Departments of State, Defense (DOD), and Homeland Security (DHS) all have a role in the FMS program. In 2003, GAO identified significant weaknesses in FMS control mechanisms for safeguarding defense articles transferred to foreign governments. In 2007, GAO designated the protection of technologies critical to U.S. national security a high-risk area. GAO was asked to (1) evaluate program changes State, DOD, and DHS have made since 2003 to ensure that unclassified defense articles transferred to foreign governments are authorized for shipment and monitored as required, and (2) determine what information DOD has to administer and oversee the FMS program. GAO conducted 16 case studies; analyzed U.S. port data and FMS agreements; reviewed program performance metrics; and interviewed cognizant officials."

Medicaid: Ongoing Federal Oversight of Payments to Offset Uncompensated Hospital Care Costs Is Warranted
A letter report issued by the Government Accountability Office with an abstract that begins "In addition to standard Medicaid payments, hospitals receive supplemental payments for uncompensated costs of care provided to uninsured and Medicaid patients. These supplemental payments are referred to as disproportionate share hospital (DSH) payments. Hospitals may also receive non-DSH supplemental payments. In fiscal year 2006, DSH payments totaled about $17 billion and non-DSH supplemental payments exceeded $6 billion. Hospitals' DSH payments are limited to their uncompensated care costs, that is, their costs for covered care less Medicaid and other payments. Concerns have been raised about the accuracy of DSH payment limits, particularly as states may estimate limits using data that are not audited or up to date. The Government Accountability Office (GAO) was asked to examine (1) how state DSH payments in 2006 compared to DSH payment limits, and (2) certain aspects of states' calculations of 2006 DSH payment limits. In selected states, GAO analyzed state Medicaid payment data and interviewed officials from the states and from the Centers for Medicare & Medicaid Services (CMS), the federal agency that oversees Medicaid."

OSHA's Voluntary Protection Programs: Improved Oversight and Controls Would Better Ensure Program Quality
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Labor's Occupational Safety and Health Administration (OSHA) is responsible for ensuring workplace safety. OSHA has established a number of programs, including the Voluntary Protection Programs (VPP), that take a cooperative approach to obtaining compliance with safety and health regulations and OSHA's standards. OSHA established the VPP in 1982 to recognize worksites with exemplary safety and health programs. GAO was asked to review (1) the number and characteristics of employer worksites in the VPP and factors that have influenced growth, (2) the extent to which OSHA ensures that only qualified worksites participate in the VPP, and (3) the adequacy of OSHA's efforts to monitor performance and evaluate the effectiveness of the VPP. GAO analyzed OSHA's VPP data, reviewed a representative sample of VPP case files, and interviewed agency officials."

U.S. Postal Service: Network Rightsizing Needed to Help Keep USPS Financially Viable
Testimony issued by the Government Accountability Office with an abstract that begins "The recession accelerated declines in mail volume in fiscal year 2008 and flattened revenues despite postal rate increases. That year, mail volume fell by 9.5 billion pieces, or 4.5 percent, and resulted in a net loss of $2.8 billion as the U.S. Postal Service's (USPS) cost-cutting did not close the gap between revenues and expenses. We testified this March before this subcommittee that USPS's financial condition has continued to deteriorate in the first 5 months of fiscal year 2009, with accelerating declines in mail volume and financial losses. USPS projected its financial condition to continue deteriorating for the rest of the fiscal year and to result in an unprecedented cash shortfall of $1.5 billion, assuming that ambitious cost-cutting targets are achieved. This testimony updates that information and focuses on (1) how USPS's financial viability is challenged given current economic conditions and whether USPS can cover its expenses and financial obligations, (2) USPS's opportunities to rightsize its retail and mail processing networks, and (3) what options and trade-offs need to be considered to address mail volume and revenue declines. It is based on GAO's past work and updated information …

Joint Strike Fighter: Strong Risk Management Essential as Program Enters Most Challenging Phase
Testimony issued by the Government Accountability Office with an abstract that begins "The F-35 Joint Strike Fighter (JSF) program is the Department of Defense's (DOD's) most costly acquisition, seeking to simultaneously develop, produce, and field three aircraft variants for the Air Force, Navy, Marine Corps, and eight international partners. The total expected U.S. investment is now more than $300 billion to develop and procure 2,456 aircraft over the next 25 years. GAO's most recent report in March of this year discussed increased development costs and schedule estimates, plans to accelerate procurement, manufacturing performance and delays, and development test strategy. A recurring theme in GAO's work has been concern about what GAO believes is undue concurrency of development, test, and production activities and the heightened risks it poses to achieving good cost, schedule, and performance outcomes. This testimony discusses: (1) current JSF cost and schedule estimates; (2) engine development; (3) manufacturing performance; (4) contracting issues for procurement of aircraft; (5) and test plans. This statement draws from GAO's March 2009 report, updated to the extent possible with new budget data and a recently revised procurement profile directed by the Secretary of Defense."

U.S. Department of Agriculture: Charges to Agencies and Offices for Centrally Provided (Greenbook) Programs for Fiscal Years 1999 through 2009 (GAO-10-83SP), an E-supplement to GAO-10-82
Other written product issued by the Government Accountability Office with an abstract that begins "This is a supplement to GAO-10-82. The U.S. Department of Agriculture (USDA) comprises 15 agencies in several broad mission areas responsible for, among other things, assisting farmers and rural communities, overseeing the safety of meat and poultry, giving low-income families access to nutritious food, and protecting the nation's forests. USDA's 12 staff offices support these mission activities. In 1965 Congress gave USDA transfer of funds authority that allows it to charge the appropriations accounts of its agencies and staff offices in order to provide certain programs centrally that benefit those agencies and offices. USDA has used this authority to support several e-government, educational, and presidential initiatives, and the USDA visitors' information center; and to fund programs that provide activities and services that USDA's agencies and staff offices would otherwise have to obtain individually, such as sign language interpreter services and a drug testing program. The Senate report accompanying USDA's fiscal year 2008 appropriations, as reported out by the Senate Appropriations Committee, expressed concern that these charges--referred to as "Greenbook" charges--have grown excessively over the last few years. Noting that the disclosure of these charges to Congress …

Space Acquisitions: DOD Faces Substantial Challenges in Developing New Space Systems
Testimony issued by the Government Accountability Office with an abstract that begins "Despite a growing investment in space, the majority of large-scale acquisition programs in the Department of Defense's (DOD) space portfolio have experienced problems during the past two decades that have driven up cost and schedules and increased technical risks. The cost resulting from acquisition problems along with the ambitious nature of space programs has resulted in cancellations of programs that were expected to require investments of tens of billions of dollars. Along with the cost increases, many programs are experiencing significant schedule delays--at least 7 years--resulting in potential capability gaps in areas such as positioning, navigation, and timing; missile warning; and weather monitoring. This testimony focuses on (1) the condition of space acquisitions, (2) causal factors, and (3) recommendations for better positioning programs and industry for success. In preparing this testimony, GAO relied on its body of work in space and other programs, including previously issued GAO reports on assessments of individual space programs, common problems affecting space system acquisitions, and DOD's acquisition policies."

Two-photon double ionization of H2 at 30 eV using Exterior Complex Scaling
Calculations of fully differential cross sections for two-photon double ionization of the hydrogen molecule with photons of 30 eV are reported. The results have been obtained by using the method of exterior complex scaling, which allows one to construct essentially exact wave functions that describe thedouble continuum on a large, but finite, volume. The calculated cross sections are compared with those previously obtained by Colgan et al., and discrepancies are found for specific molecular orientations and electron ejection directions.

Analysis of Metabolic Pathways and Fluxes in a Newly Discovered Thermophilic and Ethanol-Tolerant Geobacillus Strain
A recently discovered thermophilic bacterium, Geobacillus thermoglucosidasius M10EXG, ferments a range of C5 (e.g., xylose) and C6 sugars (e.g., glucose) and istolerant to high ethanol concentrations (10percent, v/v). We have investigated the central metabolism of this bacterium using both in vitro enzyme assays and 13C-based flux analysis to provide insights into the physiological properties of this extremophile and explore its metabolism for bio-ethanol or other bioprocess applications. Our findings show that glucose metabolism in G. thermoglucosidasius M10EXG proceeds via glycolysis, the pentose phosphate pathway, and the TCA cycle; the Entner?Doudoroff pathway and transhydrogenase activity were not detected. Anaplerotic reactions (including the glyoxylate shunt, pyruvate carboxylase, and phosphoenolpyruvate carboxykinase) were active, but fluxes through those pathways could not be accuratelydetermined using amino acid labeling. When growth conditions were switched from aerobic to micro-aerobic conditions, fluxes (based on a normalized glucose uptake rate of 100 units (g DCW)-1 h-1) through the TCA cycle and oxidative pentose phosphate pathway were reduced from 64+-3 to 25+-2 and from 30+-2 to 19+-2, respectively. The carbon flux under micro-aerobic growth was directed formate. Under fully anerobic conditions, G. thermoglucosidasius M10EXG used a mixed acid fermentation process and exhibited a maximum ethanol yield of 0.38+-0.07 mol mol-1 …

Improving Consistency of Performance Assessments in the Doe Complex
The low-level waste (LLW) performance assessment (PA) process has been traditionally focused on disposal facilities at a few United States Department of Energy (USDOE) sites and commercial disposal facilities. In recent years, there has been a dramatic increase in the scope of the use of PA-like modeling approaches, involving multiple activities, facilities, contractors and regulators. The scope now includes, for example: (1) National Environmental Policy Act (NEPA) assessments, (2) CERCLA disposal cells, (3) Waste Determinations and High-Level Waste (HLW) Closure activities, (4) Potential on-site disposal of Transuranic (TRU) waste, and (5) In-situ decommissioning (including potential use of existing facilities for disposal). The dramatic increase in the variety of activities requiring more detailed modeling has resulted in a similar increase in the potential for inconsistency in approaches both at a site and complexwide scale. This paper includes a summary of USDOE Environmental Management (EM) sponsored initiatives and activities for improved consistency. New initiatives entitled the Performance Assessment Community of Practice and Performance Assessment Assistance Team are also introduced.

DOE Award No. DE-FC36-03GO13108 Novel Non-Precious Metal Catalysts for PEMFC: Catalyst Selection Through Molecular Modeling and Durability Studies Final Report (September 2003 – October 2008)
The objective of this project is to develop novel non-precious metal electrocatalysts for oxygen reduction reaction (ORR), and demonstrate the potential of the catalysts to perform at least as good as conventional Pt catalysts currently in use in polymer electrolyte membrane fuel cell (PEMFC) with a cost at least 50 % less than a target of 0.2 g (Pt loading)/peak kW and with durability > 2,000 h operation with less than 10 % power degradation. A novel nitrogen-modified carbon-based catalyst was obtained by modifying carbon black with nitrogen-containing organic precursor in the absence of transition metal precursor. The catalyst shows the onset potential of approximately 0.76 V (NHE) for ORR and the amount of H2O2 of approximately 3% at 0.5 V (NHE). Furthermore, a carbon composite catalyst was achieved through the high-temperature pyrolysis of the precursors of transition metal (Co and Fe) and nitrogen supported on the nitrogen-modified carbon-based catalyst, followed by chemical post-treatment. This catalyst showed an onset potential for ORR as high as 0.87 V (NHE), and generated less than 1 % of H2O2. The PEM fuel cell exhibited a current density of 2.3 A cm-2 at 0.2 V for a catalyst loading of 6.0 mg cm-2. No …

Stochastic Boundary, Diffusion, Emittance Growth and Lifetime calculation for the RHIC e-lens
To compensate the large tune shift and tune spread generated by the head-on beam-beam interactions in polarized proton operation in the Relativistic Heavy Ion Collider (RHIC), a low energy electron beam with proper Gaussian transverse profiles was proposed to collide head-on with the proton beam. In this article, using a modified version of SixTrack [1], we investigate stability of the single particle in the presence of head-on beam-beam compensation. The Lyapunov exponent and action diffusion are calculated and compared between the cases without and with beam-beam compensation for two different working points and various bunch intensities. Using the action diffusion results the emittance growth rate and lifetime of the proton beam is also estimated for the different scenarios.

MEASUREMENT OF WIND SPEED FROM COOLING LAKE THERMAL IMAGERY
The Savannah River National Laboratory (SRNL) collected thermal imagery and ground truth data at two commercial power plant cooling lakes to investigate the applicability of laboratory empirical correlations between surface heat flux and wind speed, and statistics derived from thermal imagery. SRNL demonstrated in a previous paper [1] that a linear relationship exists between the standard deviation of image temperature and surface heat flux. In this paper, SRNL will show that the skewness of the temperature distribution derived from cooling lake thermal images correlates with instantaneous wind speed measured at the same location. SRNL collected thermal imagery, surface meteorology and water temperatures from helicopters and boats at the Comanche Peak and H. B. Robinson nuclear power plant cooling lakes. SRNL found that decreasing skewness correlated with increasing wind speed, as was the case for the laboratory experiments. Simple linear and orthogonal regression models both explained about 50% of the variance in the skewness - wind speed plots. A nonlinear (logistic) regression model produced a better fit to the data, apparently because the thermal convection and resulting skewness are related to wind speed in a highly nonlinear way in nearly calm and in windy conditions.

Prototype Testing for a Copper Rotatable Collimator for the LHC Collimation Upgrade
The Phase II upgrade to the LHC collimation system calls for complementing the robust Phase I graphite collimators with high Z Phase II collimators. The design for the collimation upgrade has not been finalized. One option is to use metallic rotatable collimators and testing of this design will be discussed here. The Phase II collimators must be robust in various operating conditions and accident scenarios. A prototype collimator jaw referred to as RC0 has been tested for both mechanical and thermal compliance with the design goals. Thermal expansion bench-top tests are compared to ANSYS simulation results. The prototype has also been tested in vacuum bake-out to confirm compliance with the LHC vacuum spec. CMM equipment has been used to verify the flatness of the jaw surface after heat tests and bake-out.
