Contingency Contracting: DOD, State, and USAID Contracts and Contractor Personnel in Iraq and Afghanistan

A letter report issued by the Government Accountability Office with an abstract that begins "The Departments of Defense (DOD) and State and the United States Agency for International Development (USAID) have relied extensively on contractors to carry out a range of services in Iraq and Afghanistan. While recognizing the benefits of using contractors, GAO and others have noted the challenges and risks associated with an increased reliance on contractors and the ability of agencies to manage their growing number of contractors. As directed by the National Defense Authorization Act for Fiscal Year 2008, GAO analyzed DOD, State, and USAID data on contracting activities in Iraq and Afghanistan for fiscal year 2007 and the first half of fiscal year 2008 including (1) the number and value of contracts and the extent they were awarded competitively; (2) the number of contractor personnel, including those performing security functions; and (3) the number of contractor personnel who were killed or wounded. GAO also reviewed the status of the three agencies' memorandum of understanding (MOU) related to maintaining data on contracts and contractor personnel. GAO reviewed selected contract files and compared personnel data to other available sources to assess the reliability of the data reported …

Military Readiness: Navy Is Making Progress Implementing Its Fleet Response Plan, but Has Not Fully Developed Goals, Measures, and Resource Needs (open access)

Military Readiness: Navy Is Making Progress Implementing Its Fleet Response Plan, but Has Not Fully Developed Goals, Measures, and Resource Needs

A letter report issued by the Government Accountability Office with an abstract that begins "The Navy initiated its Fleet Response Plan (FRP) in March 2003 as a critical enabler to help meet the new demands of the twenty-first century security environment. FRP represents a major change in the way the Navy manages its forces, and is intended to more rapidly prepare and then sustain readiness in ships and squadrons. To achieve the desired capabilities under FRP, the Navy has altered its training, maintenance, and manning practices. The Navy expects this new readiness approach will enable its forces to provide presence and engagement in forward areas, as well as surge a greater number of ships on short notice. The Navy intends to achieve this goal without increasing its operations and maintenance budget of about $40 billion for each of the next 5 years. However, GAO previously reported that the Navy had not fully incorporated a sound management approach to guide and assess implementation of FRP. As a result, GAO was asked to examine the extent to which the Navy has (1) made progress in implementing a sound management approach for FRP and (2) evaluated the long-term risks and tradeoffs of FRP-related …

Modeling Approach/Strategy for Corrective Action Unit 99: Rainier Mesa and Shoshone Mountain, Nevada Test Site, Nye County, Nevada, Revision 1, with ROTC-1 (open access)

Modeling Approach/Strategy for Corrective Action Unit 99: Rainier Mesa and Shoshone Mountain, Nevada Test Site, Nye County, Nevada, Revision 1, with ROTC-1

This document describes an approach for preliminary (Phase I) flow and transport modeling for the Rainier Mesa/Shoshone Mountain (RMSM) Corrective Action Unit (CAU). This modeling will take place before the planned Phase II round of data collection to better identify the remaining data gaps before the fieldwork begins. Because of the geologic complexity, limited number of borings, and large vertical gradients, there is considerable uncertainty in the conceptual model for flow; thus different conceptual models will be evaluated, in addition to different framework and recharge models. The transport simulations will not be used to formally calculate the Contaminant Boundary at this time. The modeling (Phase II) will occur only after the available data are considered sufficient in scope and quality.

Impact Tensile Testing of Stainless Steels at Various Temperatures (open access)

Impact Tensile Testing of Stainless Steels at Various Temperatures

Stainless steels are used for the construction of numerous spent nuclear fuel or radioactive material containers that may be subjected to high strains and moderate strain rates during accidental drop events. Mechanical characteristics of these base materials and their welds under dynamic loads in the strain rate range of concern (1 to 300 per second) are not well documented. However, research is being performed at the Idaho National Laboratory to quantify these characteristics. The work presented herein discusses tensile impact testing of dual-marked 304/304L and 316/316L stainless steel material specimens. Both base material and welded material specimens were tested at -20 oF, room temperature, 300 oF, and 600 oF conditions. Utilizing a drop weight impact test machine and 1/4-inch and 1/2-inch thick dog bone-shaped test specimens, a strain rate range of approximately 4 to 40 per second (depending on initial temperature conditions) was achieved. Factors were determined that reflect the amount of increased strain energy the material can absorb due to strain rate effects. Using the factors, elevated true stress-strain curves for these materials at various strain rates and temperatures were generated. By incorporating the strain rate elevated true stress-strain material curves into an inelastic finite element computer program as …

Development of nanostructured and surface modified semiconductors for hybrid organic-inorganic solar cells. (open access)

Development of nanostructured and surface modified semiconductors for hybrid organic-inorganic solar cells.

Solar energy conversion is increasingly being recognized as one of the principal ways to meet future energy needs without causing detrimental environmental impact. Hybrid organic-inorganic solar cells (SCs) are attracting particular interest due to the potential for low cost manufacturing and for use in new applications, such as consumer electronics, architectural integration and light-weight sensors. Key materials advantages of these next generation SCs over conventional semiconductor SCs are in design opportunities--since the different functions of the SCs are carried out by different materials, there are greater materials choices for producing optimized structures. In this project, we explore the hybrid organic-inorganic solar cell system that consists of oxide, primarily ZnO, nanostructures as the electron transporter and poly-(3-hexylthiophene) (P3HT) as the light-absorber and hole transporter. It builds on our capabilities in the solution synthesis of nanostructured semiconducting oxide arrays to this photovoltaic (PV) technology. The three challenges in this hybrid material system for solar applications are (1) achieving inorganic nanostructures with critical spacing that matches the exciton diffusion in the polymer, {approx} 10 nm, (2) infiltrating the polymer completely into the dense nanostructure arrays, and (3) optimizing the interfacial properties to facilitate efficient charge transfer. We have gained an understanding and control …
