A letter report issued by the Government Accountability Office with an abstract that begins "The Army Working Capital Fund (AWCF) collected over $16 billion for goods and services provided to customers in fiscal year 2009. Cash generated from sales is used by AWCF to cover its expenses such as paying employees. In light of the Army's changing role in the Middle East, GAO was asked to determine whether (1) AWCF's monthly cash balances fell within the Department of Defense's (DOD) cash requirements for fiscal years 2000 through 2009, (2) the cash transfers resulted in AWCF's monthly cash balances falling below the minimum amount required by DOD, and (3) the AWCF's projected monthly cash balances are expected to fall below DOD's minimum cash requirement for fiscal years 2010 and 2011 and actions the Army can take to manage those balances. To address these objectives, GAO (1) reviewed relevant DOD guidance, (2) obtained and analyzed AWCF budget and accounting reports containing cash information, and (3) interviewed DOD and Army officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Recognizing the humanitarian crisis in Darfur, Sudan, Congress enacted the Sudan Accountability and Divestment Act (SADA) in 2007. This law supports U.S. states' and investment companies' decisions to divest from companies with certain business ties to Sudan. It also seeks to prohibit federal contracting with these companies. GAO was asked to (1) identify actions that U.S. state fund managers and investment companies took regarding Sudan-related assets; (2) describe the factors that these entities considered in determining whether and how to divest; and (3) determine whether the U.S. government has contracted with companies identified as having certain Sudan-related business operations and assess compliance with SADA's federal contract prohibition provision. GAO surveyed states, analyzed data on investment companies and companies with Sudan-related business operations, assessed federal contracts, and reviewed documents and interviewed officials from the Securities and Exchange Commission (SEC), among other federal agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has a variety of responsibilities that utilize foreign language capabilities, including investigating transnational criminal activity and staffing ports of entry into the United States. GAO was asked to study foreign language capabilities at DHS. GAO's analysis focused on actions taken by DHS in three of its largest components--the U.S. Coast Guard, U.S. Customs and Border Protection (CBP), and Immigration and Customs Enforcement (ICE). Specifically, this report addresses the extent to which DHS has (1) assessed its foreign language needs and existing capabilities and identified any potential shortfalls and (2) developed foreign language programs and activities to address potential foreign language shortfalls. GAO analyzed DHS documentation on foreign language capabilities, interviewed DHS officials, and assessed workforce planning in three components that were selected to ensure broad representation of law enforcement and intelligence operations. While the results are not projectable, they provide valuable insights."

Final Closeout report for DE-FG02-02ER41223

To enable detailed investigations of early stage hydrothermal plume formation and abiotic and biotic plume processes we developed a new oceanographic tool. The Suspended Particulate Rosette sampling system has been designed to collect geochemical and microbial samples from the rising portion of deep-sea hydrothermal plumes. It can be deployed on a remotely operated vehicle for sampling rising plumes, on a wire-deployed water rosette for spatially discrete sampling of non-buoyant hydrothermal plumes, or on a fixed mooring in a hydrothermal vent field for time series sampling. It has performed successfully during both its first mooring deployment at the East Pacific Rise and its first remotely-operated vehicle deployments along the Mid-Atlantic Ridge. It is currently capable of rapidly filtering 24 discrete large-water-volume samples (30-100 L per sample) for suspended particles during a single deployment (e.g. >90 L per sample at 4-7 L per minute through 1 {mu}m pore diameter polycarbonate filters). The Suspended Particulate Rosette sampler has been designed with a long-term goal of seafloor observatory deployments, where it can be used to collect samples in response to tectonic or other events. It is compatible with in situ optical sensors, such as laser Raman or visible reflectance spectroscopy systems, enabling in situ …

The objective of this survey was to obtain user feedback to, among other things, determine how to organize the exponentially growing data within the Atmospheric Radiation Measurement (ARM) Climate Research Facility, and identify users’ preferred data analysis system. The survey findings appear to have met this objective, having received approximately 300 responses that give insight into the type of work users perform, usage of the data, percentage of data analysis users might perform on an ARM-hosted computing resource, downloading volume level where users begin having reservations, opinion about usage if given more powerful computing resources (including ability to manipulate data), types of tools that would be most beneficial to them, preferred programming language and data analysis system, level of importance for certain types of capabilities, and finally, level of interest in participating in a code-sharing community.

We present a detailed analysis of the structural and magnetic properties of solution-grown PtCo-CdS hybrid structures in comparison to similar free-standing PtCo alloy nanoparticles. X-ray absorption spectroscopy is utilized as a sensitive probe for identifying subtle differences in the structure of the hybrid materials. We found that the growth of bimetallic tips on a CdS nanorod substrate leads to a more complex nanoparticle structure composed of a PtCo alloy core and thin CoO shell. The core-shell architecture is an unexpected consequence of the different nanoparticle growth mechanism on the nanorod tip, as compared to free growth in solution. Magnetic measurements indicate that the PtCo-CdS hybrid structures are superparamagnetic despite the presence of a CoO shell. The use of X-ray spectroscopic techniques to detect minute differences in atomic structure and bonding in complex nanosystems makes it possible to better understand and predict catalytic or magnetic properties for nanoscale bimetallic hybrid materials.

Iron biominerals can form in neutral pH microaerophilic environments where microbes both catalyze iron oxidation and create polymers that localize mineral precipitation. In order to classify the microbial polymers that influence FeOOH mineralogy, we studied the organic and mineral components of biominerals using scanning transmission X-ray microscopy (STXM), micro X-ray fluorescence ({mu}XRF) microscopy, and high-resolution transmission electron microscopy (HRTEM). We focused on iron microbial mat samples from a creek and abandoned mine; these samples are dominated by iron oxyhydroxide-coated structures with sheath, stalk, and filament morphologies. In addition, we characterized the mineralized products of an iron-oxidizing, stalk-forming bacterial culture isolated from the mine. In both natural and cultured samples, microbial polymers were found to be acidic polysaccharides with carboxyl functional groups, strongly spatially correlated with iron oxyhydroxide distribution patterns. Organic fibrils collect FeOOH and control its recrystallization, in some cases resulting in oriented crystals with high aspect ratios. The impact of polymers is particularly pronounced as the materials age. Synthesis experiments designed to mimic the biomineralization processes show that the polysaccharide carboxyl groups bind dissolved iron strongly but release it as mineralization proceeds. Our results suggest that carboxyl groups of acidic polysaccharides are produced by different microorganisms to create a …

The speciation of Cr(VI) in Cromite Ore Processing Residue was investigated by means of bulk XRD, and a combination of micro-XRF, -XAS and -XRD at the Advanced Light Source (ALS), Berkeley, CA, U.S.A.. Bulk XRD yielded one group of phases that contained explicitly Cr(VI) in their structure, Calcium Aluminum Chromium Oxide Hydrates, accounting for 60% of the total Cr(VI). Micro-analyses at ALS yielded complimentary information, confirming that hydrogarnets and hydrotalcites, two mineral groups that can host Cr(VI) in their structure by substitution, were indeed Cr(VI) sinks. Chromatite (CaCrO4) was also identified by micro-XRD, which was not possible with bulk methods due to its low content. The acquisition of micro-XRF elemental maps enabled not only the identification of Cr(VI)-binding phases, but also the understanding of their location within the matrix. This information is invaluable when designing Cr(VI) treatment, to optimize release and availability for reduction.

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony summarizes the findings of our report on funding issues related to the Environmental Protection Agency's (EPA) Superfund program. To protect human health and the environment from the effects of hazardous substances, Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in 1980, which established the Superfund program. Since 1980, EPA has identified more than 47,000 hazardous waste sites potentially requiring cleanup. As of the end of fiscal year 2009, 1,269 of the most seriously contaminated sites were included on EPA's National Priorities List (NPL): 1,111 nonfederal sites and 158 federal facilities. At the time of listing, EPA had determined that these sites posed relatively high risks to human health or the environment from releases or threatened releases of hazardous substances, such as lead and polychlorinated biphenyl. These substances can cause a variety of health effects--such as birth defects, cancer, and developmental disorders--in people exposed to them. Of the nonfederal sites listed on the NPL at the end of fiscal year 2009, EPA identified 75 that have "unacceptable human exposure"--actual or reasonably expected exposure of an individual to hazardous substances, pollutants, or contaminants at levels …

In 2008, NANA Regional Corporation (NRC) assessed geothermal energy potential in the NANA region for both heat and/or electricity production. The Geothermal Assessment Project (GAP) was a systematic process that looked at community resources and the community's capacity and desire to develop these resources. In October 2007, the US Department of Energy's Tribal Energy Program awarded grant DE-FG36-07GO17075 to NRC for the GAP studies. Two moderately remote sites in the NANA region were judged to have the most potential for geothermal development: (1) Granite Mountain, about 40 miles south of Buckland, and (2) the Division Hot Springs area in the Purcell Mountains, about 40 miles south of Shungnak and Kobuk. Data were collected on-site at Granite Mountain Hot Springs in September 2009, and at Division Hot Springs in April 2010. Although both target geothermal areas could be further investigated with a variety of exploration techniques such as a remote sensing study, a soil geochemical study, or ground-based geophysical surveys, it was recommended that on-site or direct heat use development options are more attractive at this time, rather than investigations aimed more at electric power generation.
