A new approach to the study of material strength of metals at extreme pressures has been developed on the Omega laser, using a ramped plasma piston drive. The laser drives a shock through a solid plastic reservoir that unloads at the rear free surface, expands across a vacuum gap, and stagnates on the metal sample under study. This produces a gently increasing ram pressure, compressing the sample nearly isentropically. The peak pressure on the sample, inferred from VISAR measurements of velocity, can be varied by adjusting the laser energy and pulse length, gap size, and reservoir density, and obeys a simple scaling relation. In an important application, using in-flight x-ray radiography, the material strength of solid-state samples at high pressure can be inferred by measuring the reductions in the growth rates (stabilization) of Rayleigh-Taylor (RT) unstable interfaces. This paper reports the first attempt to use this new laser-driven, quasi-isentropic technique for determining material strength in high-pressure solids. Modulated foils of Al-6061-T6 were accelerated and compressed to peak pressures of 200 kbar. Modulation growth was recorded at a series of times after peak acceleration and well into the release phase. Fits to the growth data, using a Steinberg-Guinan (SG) constitutive strength …

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Aviation Administration's (FAA) multibillion-dollar effort to modernize the nation's air traffic control (ATC) system has resulted in cost, schedule, and performance shortfalls for over two decades and has been on GAO's list of high-risk federal programs since 1995. According to FAA, performance shortfalls were due, in part, to restrictions imposed by federal acquisition and personnel regulations. In response, Congress granted FAA exemptions in 1995 and directed it to develop a new acquisition management system. In this report, GAO compared FAA's AMS with (1) the FAR and (2) commercial best practices for major acquisitions, and (3) examined FAA's implementation of AMS and its progress in resolving problems with major acquisitions."

A letter report issued by the Government Accountability Office with an abstract that begins "Evaluations of past censuses show that certain groups were undercounted compared to other groups, a problem known as "coverage error." To address this, the Census Bureau included in its 2000 Census design the Accuracy and Coverage Evaluation Program (A.C.E.) to (1) measure coverage error and (2) use the results to adjust the census, if warranted. However, the Bureau found the A.C.E. results inaccurate and decided not to adjust or plan for adjustment in 2010. Congress asked GAO to determine (1) factors contributing to A.C.E.'s reported failure to accurately estimate census coverage error, and (2) the reliability of the revised coverage error estimates the Bureau subsequently produced. To do this, GAO examined three sets of Bureau research published in March 2001, October 2001, and March 2003 and interviewed Bureau officials."

A letter report issued by the Government Accountability Office with an abstract that begins "A lack of servicemember health and deployment data hampered investigations into the nature and causes of illnesses reported by many servicemembers following the 1990-91 Persian Gulf War. Public Law 105-85, enacted in November 1997, required the Department of Defense (DOD) to establish a system to assess the medical condition of servicemembers before and after deployments. Following its September 2003 report examining Army and Air Force compliance with DOD's force health protection and surveillance policies for Operation Enduring Freedom (OEF) and Operation Joint Guardian (OJG), GAO was asked in November 2003 to also determine (1) the extent to which the services met DOD's policies for Operation Iraqi Freedom (OIF) and, where applicable, compare results with OEF/OJG; and (2) what steps DOD has taken to establish a quality assurance program to ensure that the military services comply with force health protection and surveillance policies."

The Emergency Alert System (EAS) is one of several federally managed warning systems. The Federal Emergency Management Agency (FEMA) jointly administers EAS with the Federal Communications Commission (FCC), in cooperation with the National Weather Service (NWS), an organization within the National Oceanic and Atmospheric Administration (NOAA). The NOAA/NWS weather radio system has been upgraded to an all-hazard warning capability. This report summarizes the technology and administration of EAS and the NOAA/NWS all-hazard network, and some of the key proposals for change

A new, highly energy efficient approach for using catalytic oxidation chemistry in multiple fields of technology has been pursued. The new catalysts, called TAML® activators, catalyze the reactions of hydrogen peroxide and other oxidants for the exceptionally rapid decontamination of noninfectious simulants (B. atrophaeus) of anthrax spores, for the energy efficient decontamination of thiophosphate pesticides, for the facile, low temperature removal of color and organochlorines from pulp and paper mill effluent, for the bleaching of dyes from textile mill effluents, and for the removal of recalcitrant dibenzothiophene compounds from diesel and gasoline fuels. Highlights include the following: 1) A 7-log kill of Bacillus atrophaeus spores has been achieved unambiguously in water under ambient conditions within 15 minutes. 2) The rapid total degradation under ambient conditions of four thiophosphate pesticides and phosphonate degradation intermediates has been achieved on treatment with TAML/peroxide, opening up potential applications of the decontamination system for phosphonate structured chemical warfare agents, for inexpensive, easy to perform degradation of stored and aged pesticide stocks (especially in Africa and Asia), for remediation of polluted sites and water bodies, and for the destruction of chemical warfare agent stockpiles. 3) A mill trial conducted in a Pennsylvanian bleached kraft pulp mill …

In the DOE award, DE-FG02-00ER45823, we have used molecular dynamics (MD) computer simulations of the intergranular films (IGFs) present in alumina and silicon nitride materials to address specific questions such as: What is the atomistic structure of the glassy silicate phase? Because of the extremely thin nature of the IGF, do bulk-like glass structure and properties prevail? Does distortion exist in the silicate bonds (which affects bond strength and reactivity) and how is this structure affected by the separation distance between the crystals and/or by the composition of the IGF? Does a structural ordering caused by epitaxial adsorption occur at the IGF/crystal interface? What is the correlation length of this order perpendicular to the interface? How is this ordering affected by composition of the IGF or by the crystals in question? In all simulations, a specific number of ions in stoichiometric ratio were placed as the IGF between two similar crystals, with, in some cases, different crystallographic orientations. The IGF compositions coincided with some of those observed experimentally (calcium aluminosilicate (CAS) glasses in the alumina case, calcium silicon oxy-nitride in the nitride case). The number of ions in the IGF was varied to allow for different thicknesses, although the X …

A successful ignition campaign will depend in part upon having highly characterized hohlraums and shells for target assemblies. Regarding holhraums, properties of interest include dimensions, surface features and chemical composition. This report outlines the metrology needs for hohlraums and provides a timeline for capital as well as FTE expenditures through '07. The topics discussed include hohlraum metrology, windows and tenting metrology, with comments on support of other areas including cryo-related development efforts. Although there is a strong interest in non-destructive characterization, this report also investigates the use of destructive techniques for providing critical information for process development and improvement.
