Military Personnel: Guidance Needed for Any Future Conversions of Military Medical Positions to Civilian Positions

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "Since September 11, 2001, the high pace of military operations has placed significant stress on U.S. operating forces. In late 2003, the Department of Defense (DOD) reported that several studies had found that tens of thousands of military personnel were performing tasks that were not military essential and that these tasks could be performed more cost effectively by civilian or private-sector contract e… more

Highway Public-Private Partnerships: More Rigorous Up-front Analysis Could Better Secure Potential Benefits and Protect the Public Interest

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The United States is at a critical juncture in addressing the demands on its transportation system, including highway infrastructure. State and local governments are looking for alternatives, including increased private sector participation. GAO was asked to review (1) the benefits, costs, and trade-offs of public-private partnerships; (2) how public officials have identified and acted to protect the pu… more

Elections: Results of GAO's Testing of Voting Systems Used in Sarasota County in Florida's 13th Congressional District

Description: A statement of record issued by the Government Accountability Office with an abstract that begins "In November 2006, about 18,000 undervotes were reported in Sarasota County in the race for Florida's 13th Congressional District (Florida-13). After the election results were contested in the House of Representatives, the task force unanimously voted to seek GAO's assistance in determining whether the voting systems contributed to the large undervote in Sarasota County. In October 2007, GAO presen… more

Defense Logistics: Army Has Not Fully Planned or Budgeted for the Reconstitution of Its Afloat Prepositioned Stocks

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "At various stages throughout the current operations in Iraq and Afghanistan, the Army has withdrawn equipment from its stored, or prepositioned, stock sets around the world, as well as from its afloat stocks, thus depleting a large portion of its prepositioned stocks. The Army prepositions equipment at diverse strategic locations in order to field combat-ready forces in days rather than the weeks it woul… more

VA Health Care: Mild Traumatic Brain Injury Screening and Evaluation Implemented for OEF/OIF Veterans, but Challenges Remain

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Traumatic brain injury (TBI) has emerged as a leading injury among servicemembers serving in the Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) combat theaters. The widespread use of improvised explosive devices, such as roadside bombs, in these combat theaters increases the likelihood that servicemembers will be exposed to incidents that can cause a TBI. TBIs can vary from mild to s… more

Developing the Physics Basis of Fast Ignition Experiments at Future Large Fusion-class lasers

Description: The Fast Ignition (FI) concept for Inertial Confinement Fusion (ICF) has the potential to provide a significant advance in the technical attractiveness of Inertial Fusion Energy (IFE) reactors. FI differs from conventional 'central hot spot' (CHS) target ignition by using one driver (laser, heavy ion beam or Z-pinch) to create a dense fuel and a separate ultra-short, ultra-intense laser beam to ignite the dense core. FI targets can burn with {approx} 3X lower density fuel than CHS targets, resu… more

A Detailed Chemical Kinetic Reaction Mechanism for Oxidation of Four Small Alkyl Esters in Laminar Premixed Flames

Description: A detailed chemical kinetic reaction mechanism has been developed for a group of four small alkyl ester fuels, consisting of methyl formate, methyl acetate, ethyl formate and ethyl acetate. This mechanism is validated by comparisons between computed results and recently measured intermediate species mole fractions in fuel-rich, low pressure, premixed laminar flames. The model development employs a principle of similarity of functional groups in constraining the H atom abstraction and unimolecul… more

In-situ monitoring of surface post-processing in large aperture fused silica optics with Optical Coherence Tomography

Description: Optical Coherence Tomography is explored as a method to image laser-damage sites located on the surface of large aperture fused silica optics during post-processing via CO{sub 2} laser ablation. The signal analysis for image acquisition was adapted to meet the sensitivity requirements for this application. A long-working distance geometry was employed to allow imaging through the opposite surface of the 5-cm thick optic. The experimental results demonstrate the potential of OCT for remote monit… more

Decomposition of Large Scale Semantic Graphsvia an Efficient Communities Algorithm

Description: Semantic graphs have become key components in analyzing complex systems such as the Internet, or biological and social networks. These types of graphs generally consist of sparsely connected clusters or 'communities' whose nodes are more densely connected to each other than to other nodes in the graph. The identification of these communities is invaluable in facilitating the visualization, understanding, and analysis of large graphs by producing subgraphs of related data whose interrelationship… more

Autofluorescence dynamics during reperfusion following long-term renal ischemia in a rat model

Description: Optical properties of near-surface kidney tissue were monitored in order to assess response during reperfusion to long (20 minutes) versus prolonged (150 minutes) ischemia in an in vivo rat model. Specifically, autofluorescence images of the exposed surfaces of both the normal and the ischemic kidneys were acquired during both injury and reperfusion alternately under 355 nm and 266 nm excitations. The temporal profile of the emission of the injured kidney during the reperfusion phase under 355 … more

Pressure Induced Bonding Changes in Carbon Dioxide: Six Fold Coordinated CO2

Description: In this LDRD, we examined in detail the pressure-induced bonding and local coordination changes leading to the molecular {yields} associated {yields} extended-solid transitions in carbon dioxide (CO{sub 2}). We studied the progressive delocalization of electrons from the C=O molecular double bond at high pressures and temperatures, and determined the phase stability and physical properties of a new extended-solid CO{sub 2} phase (VI). We find that the new CO{sub 2} phase VI is based on a networ… more
