VA and IHS: Further Action Needed to Collaborate on Providing Health Care to Native American Veterans

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) and the Indian Health Service (IHS) have developed mechanisms to implement and monitor their memorandum of understanding (MOU); however, the performance metrics developed to assess its implementation do not adequately measure progress made toward its goals. VA and IHS have defined common goals for implementing the MOU and developed strategies to achieve them. They have also created two mechanisms to implement the MOU--12 workgroups with members from both agencies to address the goals of the MOU, and a Joint Implementation Task Force, comprised of VA and IHS officials, to oversee the MOU's implementation. These steps are consistent with practices that GAO has found enhance and sustain agency collaboration. The agencies have also developed three metrics aimed at measuring progress toward the MOU's goals. However, two of the three metrics are inadequate because their connection to any specific MOU goal is not clear and, while they include quantitative measures that tally the number of programs and activities increased or enhanced as a result of the MOU, they lack qualitative measures that would allow the agencies to assess the degree to which …

President's Emergency Plan For AIDS Relief: Drug Supply Chains Are Stronger, but More Steps Are Needed to Reduce Risks

A letter report issued by the Government Accountability Office with an abstract that begins "The President's Emergency Plan for AIDS Relief (PEPFAR) has worked with U.S. implementing agencies, international donors, and partner countries to increase the efficiency and reliability of antiretroviral (ARV) drug supply chains. It has done so by improving drug supply planning and procurement as well as incountry distribution of drugs. First, PEPFAR has consolidated supply chains for ARV drug procurement for more than 20 partner countries to enhance efficiency and reduce costs and has begun further consolidation with other U.S. global health programs. Second, PEPFAR has improved coordination among donors by creating an information-sharing network to help detect and resolve supply gaps and other supply chain weaknesses and by developing an emergency drug procurement mechanism. Third, PEPFAR has provided partner countries with technical assistance, such as assessment tools and training, to help them better manage drug supply planning, procurement, and distribution."

Department of Homeland Security: Opportunities Exist to Strengthen Efficiency and Effectiveness, Achieve Cost Savings, and Improve Management Functions

Testimony issued by the Government Accountability Office with an abstract that begins "Since 2011, GAO has identified 11 areas across the Department of Homeland Security (DHS) where fragmentation, overlap, or potential duplication exists and 13 areas of opportunity for cost savings or enhanced revenue collections. In these reports, GAO has suggested 53 total actions to the department and Congress to help strengthen the efficiency and effectiveness of DHS operations. In GAO’s 2013 annual report on federal programs, agencies, offices, and initiatives that have duplicative goals or activities, GAO identified 6 new areas where DHS could take actions to address fragmentation, overlap, or potential duplication or achieve significant cost savings. For example, GAO found that DHS does not have a department-wide policy defining research and development (R&D) or guidance directing components how to report R&D activities. Thus, DHS does not know its total annual investment in R&D, which limits its ability to oversee components’ R&D efforts. In particular, GAO identified at least 6 components with R&D activities and an additional $255 million in R&D obligations in fiscal year 2011 by DHS components that was not centrally tracked. GAO suggested that DHS develop and implement policies and guidance for defining and overseeing …

On the Singularity of the Vlasov-Poisson System (open access)

On the Singularity of the Vlasov-Poisson System

The Vlasov-Poisson system can be viewed as the collisionless limit of the corresponding Fokker- Planck-Poisson system. It is reasonable to expect that the result of Landau damping can also be obtained from the Fokker-Planck-Poisson system when the collision frequency v#23; approaches zero. However, we show that the colllisionless Vlasov-Poisson system is a singular limit of the collisional Fokker-Planck-Poisson system, and Landau's result can be recovered only as the #23; approaching zero from the positive side.

Rheology and TIC/TOC results of ORNL tank samples (open access)

Rheology and TIC/TOC results of ORNL tank samples

The Savannah River National Laboratory (SRNL)) was requested by Oak Ridge National Laboratory (ORNL) to perform total inorganic carbon (TIC), total organic carbon (TOC), and rheological measurements for several Oak Ridge tank samples. As received slurry samples were diluted and submitted to SRNL-Analytical for TIC and TOC analyses. Settled solids yield stress (also known as settled shear strength) of the as received settled sludge samples were determined using the vane method and these measurements were obtained 24 hours after the samples were allowed to settled undisturbed. Rheological or flow properties (Bingham Plastic viscosity and Bingham Plastic yield stress) were determined from flow curves of the homogenized or well mixed samples. Other targeted total suspended solids (TSS) concentrations samples were also analyzed for flow properties and these samples were obtained by diluting the as-received sample with de-ionized (DI) water.

Sludge Washing And Demonstration Of The DWPF Flowsheet In The SRNL Shielded Cells For Sludge Batch 8 Qualification (open access)

Sludge Washing And Demonstration Of The DWPF Flowsheet In The SRNL Shielded Cells For Sludge Batch 8 Qualification

The current Waste Solidification Engineering (WSE) practice is to prepare sludge batches in Tank 51 by transferring sludge from other tanks to Tank 51. Tank 51 sludge is washed and transferred to Tank 40, the current Defense Waste Processing Facility (DWPF) feed tank. Prior to transfer of Tank 51 to Tank 40, the Savannah River National Laboratory (SRNL) typically simulates the Tank Farm and DWPF processes using a Tank 51 sample (referred to as the qualification sample). WSE requested the SRNL to perform characterization on a Sludge Batch 8 (SB8) sample and demonstrate the DWPF flowsheet in the SRNL shielded cells for SB8 as the final qualification process required prior to SB8 transfer from Tank 51 to Tank 40. A 3-L sample from Tank 51 (the SB8 qualification sample; Tank Farm sample HTF-51-12-80) was received by SRNL on September 20, 2012. The as-received sample was characterized prior to being washed. The washed material was further characterized and used as the material for the DWPF process simulation including a Sludge Receipt and Adjustment Tank (SRAT) cycle, a Slurry Mix Evaporator (SME) cycle, and glass fabrication and chemical durability measurements.

Molecular Characterization of Bacterial Respiration on Minerals (open access)

Molecular Characterization of Bacterial Respiration on Minerals

The overall aim of this project was to contribute to our fundamental understanding of proteins and biological processes under extreme environmental conditions. We sought to define the biochemical and physiological mechanisms that underlie biodegradative and other cellular processes in normal, extreme, and engineered environments. Toward that end, we sought to understand the substrate oxidation pathways, the electron transport mechanisms, and the modes of energy conservation employed during respiration by bacteria on soluble iron and insoluble sulfide minerals. In accordance with these general aims, the specific aims were two-fold: To identify, separate, and characterize the extracellular biomolecules necessary for aerobic respiration on iron under strongly acidic conditions; and to elucidate the molecular principles whereby these bacteria recognize and adhere to their insoluble mineral substrates under harsh environmental conditions. The results of these studies were described in a total of nineteen manuscripts. Highlights include the following: 1. The complete genome of Acidithiobacillus ferrooxidans ATCC 23270 (type strain) was sequenced in collaboration with the DOE Joint Genome Institute; 2. Genomic and mass spectrometry-based proteomic methods were used to evaluate gene expression and in situ microbial activity in a low-complexity natural acid mine drainage microbial biofilm community. This was the first effort to successfully …

Quantifying Climate Feedbacks from Abrupt Changes in High-Latitude Trace-Gas Emissions (open access)

Quantifying Climate Feedbacks from Abrupt Changes in High-Latitude Trace-Gas Emissions

Our overall goal was to quantify the potential for threshold changes in natural emission rates of trace gases, particularly methane and carbon dioxide, from pan-arctic terrestrial systems under the spectrum of anthropogenically forced climate warming, and the extent to which these emissions provide a strong feedback mechanism to global climate warming. This goal is motivated under the premise that polar amplification of global climate warming will induce widespread thaw and degradation of the permafrost, and would thus cause substantial changes in the extent of wetlands and lakes, especially thermokarst (thaw) lakes, over the Arctic. Through a coordinated effort of field measurements, model development, and numerical experimentation with an integrated assessment model framework, we have investigated the following hypothesis: There exists a climate-warming threshold beyond which permafrost degradation becomes widespread and thus instigates strong and/or sharp increases in methane emissions (via thermokarst lakes and wetland expansion). These would outweigh any increased uptake of carbon (e.g. from peatlands) and would result in a strong, positive feedback to global climate warming.
