Defense Acquisitions: Opportunities Exist to Position Army's Ground Force Modernization Efforts for Success

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2003, the Future Combat System (FCS) program has been the centerpiece of the Army's efforts to transition to a lighter, more agile, and more capable combat force. In 2009, however, concerns over the program's performance led to the Secretary of Defense's decision to significantly restructure and ultimately cancel the program. As a result, the Army has outlined a new approach to ground force modernization. This report (1) outlines the Army's preliminary post-FCS plans and (2) identifies the challenges and opportunities the Department of Defense (DOD) and the Army must address as they proceed with Army ground force modernization efforts. To meet these objectives, GAO reviewed key documents, performed analyses, visited test facilities where the Army evaluated FCS equipment, and interviewed DOD and Army officials."

Enhanced Attenuation Technologies: Passive Soil Vapor Extraction (open access)

Enhanced Attenuation Technologies: Passive Soil Vapor Extraction

Passive soil vapor extraction (PSVE) is an enhanced attenuation (EA) approach that removes volatile contaminants from soil. The extraction is driven by natural pressure gradients between the subsurface and atmosphere (Barometric Pumping), or by renewable sources of energy such as wind or solar power (Assisted PSVE). The technology is applicable for remediating sites with low levels of contamination and for transitioning sites from active source technologies such as active soil vapor extraction (ASVE) to natural attenuation. PSVE systems are simple to design and operate and are more cost effective than active systems in many scenarios. Thus, PSVE is often appropriate as an interim-remedial or polishing strategy. Over the past decade, PSVE has been demonstrated in the U.S. and in Europe. These demonstrations provide practical information to assist in selecting, designing and implementing the technology. These demonstrations indicate that the technology can be effective in achieving remedial objectives in a timely fashion. The keys to success include: (1) Application at sites where the residual source quantities, and associated fluxes to groundwater, are relatively low; (2) Selection of the appropriate passive energy source - barometric pumping in cases with a deep vadose zone and barrier (e.g., clay) layers that separate the subsurface …

Fast Ferroelectric L-Band Tuner for ILC Cavities (open access)

Fast Ferroelectric L-Band Tuner for ILC Cavities

Design, analysis, and low-power tests are described on a 1.3 GHz ferroelectric tuner that could find application in the International Linear Collider or in Project X at Fermi National Accelerator Laboratory. The tuner configuration utilizes a three-deck sandwich imbedded in a WR-650 waveguide, in which ferroelectric bars are clamped between conducting plates that allow the tuning bias voltage to be applied. Use of a reduced one-third structure allowed tests of critical parameters of the configuration, including phase shift, loss, and switching speed. Issues that were revealed that require improvement include reducing loss tangent in the ferroelectric material, development of a reliable means of brazing ferroelectric elements to copper parts of the tuner, and simplification of the mechanical design of the configuration.

Final Report for DOE Project Number: DE-FG02-05ER46241 (open access)

Final Report for DOE Project Number: DE-FG02-05ER46241

Hydrogen storage is the most challenging task for the hydrogen economy. We established a multidisciplinary research program for high throughput combinatorial synthesis and characterization of novel nanoporous and metastable complex hydrides, coupled to fundamental material studies including electronic, structural and kinetic transport modeling, and pump-probe experiments. Our research is based the concept of hybrid nanostructures that store hydrogen by a combination of chemi- and physorption: atomic hydrogen is stored in metastable hydrides while molecule hydrogen is stored in the nanometer pores of the hydrides. Metastable nanostructured hydride has been achieved by introducing structural and compositional disorders through high throughput elemental substitution/doping, catalyst addition, and nonequilibrium processing. Fast screening compatible with the combinatorial synthesis was achieved by combining X-ray structural characterization with the development of a laser-based microbalance. Manufacturing of nanoporous metahydrides that are identified as promising by the combinatorial synthesis has been explored along with the materials search.

Oil and Gas Management: Interior's Oil and Gas Production Verification Efforts Do Not Provide Reasonable Assurance of Accurate Measurement of Production Volumes (open access)

Oil and Gas Management: Interior's Oil and Gas Production Verification Efforts Do Not Provide Reasonable Assurance of Accurate Measurement of Production Volumes

A letter report issued by the Government Accountability Office with an abstract that begins "Oil and natural gas produced from federal leases generated over $6.5 billion in royalties in 2009. To verify that royalties are paid on the correct volumes of oil and gas, the Department of the Interior (Interior) verifies the quantity and quality of oil and gas, both onshore, through the Bureau of Land Management, and offshore, through the Offshore Energy and Minerals Management Service. This report assesses (1) the extent to which Interior's production verification regulations and policies provide reasonable assurance that oil and gas are accurately measured; (2) the extent to which Interior's offshore and onshore production accountability inspection programs consistently set and meet program goals and address key factors affecting measurement accuracy; and (3) Interior's management of its production verification programs. To address these questions, GAO analyzed Interior data on oil and gas inspections and human capital, as well as interviewed officials from Interior, states, oil and gas companies, and other countries."

Recent International R&D Activities in the Extraction of Uranium from Seawater (open access)

Recent International R&D Activities in the Extraction of Uranium from Seawater

A literature survey has been conducted to collect information on the International R&D activities in the extraction of uranium from seawater for the period from the 1960s till the year of 2010. The reported activities, on both the laboratory scale bench experiments and the large scale marine experiments, were summarized by country/region in this report. Among all countries where such activities have been reported, Japan has carried out the most advanced large scale marine experiments with the amidoxime-based system, and achieved the collection efficiency (1.5 g-U/kg-adsorbent for 30 days soaking in the ocean) that could justify the development of industrial scale marine systems to produce uranium from seawater at the price competitive with those from conventional uranium resources. R&D opportunities are discussed for improving the system performance (selectivity for uranium, loading capacity, chemical stability and mechanical durability in the sorption-elution cycle, and sorption kinetics) and making the collection of uranium from seawater more economically competitive.
