Defense Acquisitions: Future Aerostat and Airship Investment Decisions Drive Oversight and Coordination Needs

A letter report issued by the Government Accountability Office with an abstract that begins "GAO identified 15 key aerostat and airship efforts that were underway or had been initiated since 2007, and the Department of Defense (DOD) had or has primary responsibility for all of these efforts. None of the civil agency efforts met GAO's criteria for a key effort. Most of the aerostat and airship efforts have been fielded or completed, and are intended to provide intelligence, surveillance, and reconnaissance (ISR) support. The estimated total funding of these efforts was almost $7 billion from fiscal years 2007 through 2012. However, funding estimates beyond fiscal year 2012 decline precipitously for aerostat and airship efforts under development, although there is an expectation that investment in the area will continue."

DEVELOPMENT OF HTS CONDUCTORS FOR ELECTRIC POWER APPLICATIONS (open access)

DEVELOPMENT OF HTS CONDUCTORS FOR ELECTRIC POWER APPLICATIONS

Second generation (2G) technologies to fabricate high-performance superconducting wires developed at the Oak Ridge National Laboratory (ORNL) were transferred to American Superconductor via this CRADA. In addition, co-development of technologies for over a decade was done to enable fabrication of commercial high-temperature superconducting (HTS) wires with high performance. The massive success of this CRADA has allowed American Superconductor Corporation (AMSC) to become a global leader in the fabrication of HTS wire and the technology is fully based on the Rolling Assisted Biaxially Textured Substrates (RABiTS) technology invented and developed at ORNL.

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012 (open access)

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012

The delicate balance among cellular pathways that control mutagenic changes in DNA will be the focus of the 2012 Mutagenesis Gordon Research Conference. Mutagenesis is essential for evolution, while genetic stability maintains cellular functions in all organisms from microbes to metazoans. Different systems handle DNA lesions at various times of the cell cycle and in different places within the nucleus, and inappropriate actions can lead to mutations. While mutation in humans is closely linked to disease, notably cancers, mutational systems can also be beneficial. The conference will highlight topics of beneficial mutagenesis, including full establishment of the immune system, cell survival mechanisms, and evolution and adaptation in microbial systems. Equal prominence will be given to detrimental mutation processes, especially those involved in driving cancer, neurological diseases, premature aging, and other threats to human health. Provisional session titles include Branching Pathways in Mutagenesis; Oxidative Stress and Endogenous DNA Damage; DNA Maintenance Pathways; Recombination, Good and Bad; Problematic DNA Structures; Localized Mutagenesis; Hypermutation in the Microbial World; and Mutation and Disease.

Department of Defense's Waiver of Competitive Prototyping Requirement for Enhanced Polar System Program (open access)

Department of Defense's Waiver of Competitive Prototyping Requirement for Enhanced Polar System Program

Correspondence issued by the Government Accountability Office with an abstract that begins "DOD's rationale for waiving WSARA's competitive prototyping requirement for CAPS covered both bases provided in the statute; however, DOD did not provide complete information about the potential benefits of competitive prototyping or support for its conclusion that prototyping would result in schedule delays. In the waiver, DOD found reasonable the Air Force's conclusion that the additional $49 million cost of producing competing prototypes exceeded the negligible expected life-cycle benefits because minimal opportunities exist to increase CAPS technological and design maturity through competitive prototyping. The Air Force's conclusions about CAPS technical and design risk are supported by its market research, but its cost-benefit analysis was incomplete because neither the waiver nor the business case analysis supporting it provided an estimated dollar value for the expected benefits. Further, the Air Force's cost estimate of competitively prototyping CAPS was based on a program office estimate, which has not been independently reviewed by DOD's Office of Cost Assessment and Performance Evaluation. DOD also did not provide support in the waiver for its conclusion that implementing competitive prototyping will delay EPS's initial operational capability and result in DOD being unable to meet critical …

EFFECT OF CHLORIDE AND SULFATE CONCENTRATION ON PROBABLITY BASED CORROSION CONTROL FOR LIQUID WASTE TANKS- PART IV (open access)

EFFECT OF CHLORIDE AND SULFATE CONCENTRATION ON PROBABLITY BASED CORROSION CONTROL FOR LIQUID WASTE TANKS- PART IV

A series of cyclic potentiodynamic polarization tests was performed on samples of A537 carbon steel in support of a probability-based approach to evaluate the effect of chloride and sulfate on corrosion susceptibility. Testing solutions were chosen to build off previous experimental results from FY07, FY08, FY09 and FY10 to systemically evaluate the influence of the secondary aggressive species, chloride, and sulfate. The FY11 results suggest that evaluating the combined effect of all aggressive species, nitrate, chloride, and sulfate, provides a consistent response for determining corrosion susceptibility. The results of this work emphasize the importance for not only nitrate concentration limits, but also chloride and sulfate concentration limits as well.

Entrepreneurial Assistance: Opportunities Exist to Improve Programs' Collaboration, Data-Tracking, and Performance Management

A letter report issued by the Government Accountability Office with an abstract that begins "Federal efforts to support entrepreneurs are fragmented--including among 52 programs at the Department of Agriculture (USDA), Commerce, and Housing and Urban Development (HUD) and the Small Business Administration (SBA). All overlap with at least one other program in terms of the type of assistance they are authorized to offer, such as financial (grants and loans) and technical (training and counseling), and the type of entrepreneur they are authorized to serve. Some entrepreneurs struggle to navigate the fragmented programs that provide technical assistance. For example, some entrepreneurs and technical assistance providers GAO spoke with said the system can be confusing and that some entrepreneurs do not know where to go for assistance. Collaboration could reduce some negative effects of overlap and fragmentation, but field staff GAO spoke with did not consistently collaborate to provide training and counseling services to entrepreneurs. The agencies have taken initial steps to improve how they collaborate by entering into formal agreements, but they have not pursued a number of other good collaborative practices GAO has previously identified. For example, USDA and SBA entered into a formal agreement in 2010 to coordinate their …

Method Evaluation And Field Sample Measurements For The Rate Of Movement Of The Oxidation Front In Saltstone (open access)

Method Evaluation And Field Sample Measurements For The Rate Of Movement Of The Oxidation Front In Saltstone

The objective of this work was to develop and evaluate a series of methods and validate their capability to measure differences in oxidized versus reduced saltstone. Validated methods were then applied to samples cured under field conditions to simulate Performance Assessment (PA) needs for the Saltstone Disposal Facility (SDF). Four analytical approaches were evaluated using laboratory-cured saltstone samples. These methods were X-ray absorption spectroscopy (XAS), diffuse reflectance spectroscopy (DRS), chemical redox indicators, and thin-section leaching methods. XAS and thin-section leaching methods were validated as viable methods for studying oxidation movement in saltstone. Each method used samples that were spiked with chromium (Cr) as a tracer for oxidation of the saltstone. The two methods were subsequently applied to field-cured samples containing chromium to characterize the oxidation state of chromium as a function of distance from the exposed air/cementitious material surface.

Modified Magnetic Ground State in Nimn (2) O (4) Thin Films (open access)

Modified Magnetic Ground State in Nimn (2) O (4) Thin Films

The authors demonstrate the stabilization of a magnetic ground state in epitaxial NiMn{sub 2}O{sub 4} (NMO) thin films not observed in their bulk counterpart. Bulk NMO exhibits a magnetic transition from a paramagnetic phase to a collinear ferrimagnetic moment configuration below 110 K and to a canted moment configuration below 70 K. By contrast, as-grown NMO films exhibit a single magnetic transition at 60 K and annealed films exhibit the magnetic behavior found in bulk. Cation inversion and epitaxial strain are ruled out as possible causes for the new magnetic ground state in the as-grown films. However, a decrease in the octahedral Mn{sup 4+}:Mn{sup 3+} concentration is observed and likely disrupts the double exchange that produces the magnetic state at intermediate temperatures. X-ray magnetic circular dichroism and bulk magnetometry indicate a canted ferrimagnetic state in all samples at low T. Together these results suggest that the collinear ferrimagnetic state observed in bulk NMO at intermediate temperatures is suppressed in the as grown NMO thin films due to a decrease in octahedral Mn{sup 4+}, while the canted moment ferrimagnetic ordering is preserved below 60 K.
