Correspondence issued by the Government Accountability Office with an abstract that begins "Military servicemembers engaged in combat tours in Afghanistan and Iraq are at risk of developing combat-related mental health conditions, including post-traumatic stress disorder (PTSD). In many cases, signs of potential mental health conditions do not surface until months after servicemembers return from deployment. In 2004, Army researchers published a series of articles that indicated a significant increase in the number of servicemembers reporting mental health concerns 90 to 120 days after returning from deployment, compared with mental health concerns reported before or soon after deployment. These findings led the Department of Defense (DOD) in March 2005 to develop requirements and policies for the post-deployment health reassessment (PDHRA) as part of its continuum of deployment health assessments for servicemembers. PDHRA is a screening tool for military servicemembers; it is designed to identify and address their health concerns--including mental health concerns--90 to 180 days after return from deployment. Servicemembers answer a set of questions about their physical and mental health conditions and concerns, and health care providers review the answers and refer servicemembers for further evaluation and treatment if necessary. A November 2007 study showed that a larger number of …

A letter report issued by the Government Accountability Office with an abstract that begins "Concentrated Animal Feeding Operations (CAFO) are large livestock and poultry operations that raise animals in a confined situation. CAFOs can improve the efficiency of animal production but large amounts of manure produce can, if not properly managed, degrade air and water quality. The Environmental Protection Agency (EPA) is responsible for regulating CAFOs and requires CAFOs that discharge certain pollutants to obtain a permit. This report discusses the (1) trends in CAFOs over the past 30 years, (2) amounts of waste they generate, (3) findings of key research on CAFOs' health and environmental impacts, (4) EPA's progress in developing CAFO air emissions protocols, and (5) effect of recent court decisions on EPA's regulation of CAFO water pollutants. GAO analyzed U.S. Department of Agriculture's (USDA) data from 1982 through 2002, for large farms as a proxy for CAFOs; reviewed studies, EPA documents, laws, and regulations; and obtained the views of federal and state officials."

Correspondence issued by the Government Accountability Office with an abstract that begins "In the years since the 2001 terrorist attacks, balancing the need to secure U.S. borders while maintaining the flow of legitimate cross-border travel and commerce has taken on an added importance. The United States and Canada share a border that extends nearly 4,000 miles, and one of the world's largest trading relationships. Each year, approximately 70 million travelers and 35 million vehicles cross the border from Canada into the United States, according to the Department of Homeland Security (DHS). Given the volume of cross-border travel and trade between the United States and Canada, border congestion and the resulting wait times have a substantial economic impact on both nations. Furthermore, according to an analysis by DHS, the heightened emphasis on border security following the 2001 terrorist attacks has lengthened processing time for travelers and cargo crossing into the United States. Recognizing the need to improve both border security and border-crossing efficiency, the United States and Canada have cooperated on various cross-border management initiatives intended to increase the flow of legitimate travel across the border while maintaining security. For example, to facilitate the travel of low-risk prescreened individuals across the …

Optical probes used in velocimetry measurements have typically been individual probes that collect data for a single diagnostic at a single point. These probes have been used in diagnostics such as VISAR, PDV, and radiometry, which measure surface velocity, temperature, and other characteristics. When separate probes are used for these measurements, the different diagnostic points measured must be significantly separated. We have developed integrated probes that collect data for multiple optical diagnostics; these probes measure points in close proximity.

The Materials Science and Technology (MST) Handbook was developed by Pacific Northwest National Laboratory, in Richland, Washington, under support from the U.S. Department of Energy. Many individuals have been involved in writing and reviewing materials for this project since it began at Richland High School in 1986, including contributions from educators at the Northwest Regional Education Laboratory, Central Washington University, the University of Washington, teachers from Northwest Schools, and science and education personnel at Pacific Northwest National Laboratory. Support for its development was also provided by the U.S. Department of Education. This introductory course combines the academic disciplines of chemistry, physics, and engineering to create a materials science and technology curriculum. The course covers the fundamentals of ceramics, glass, metals, polymers and composites. Designed to appeal to a broad range of students, the course combines hands-on activities, demonstrations and long term student project descriptions. The basic philosophy of the course is for students to observe, experiment, record, question, seek additional information, and, through creative and insightful thinking, solve problems related to materials science and technology. The MST Teacher Handbook contains a course description, philosophy, student learning objectives, and instructional approach and processes. Science and technology teachers can collaborate to build …

Liquid Waste Organization (LWO) identified aluminum dissolution as a method to mitigate the effect of having about 50% more solids in High Level Waste (HLW) sludge than previously planned. Previous aluminum dissolution performed in a HLW tank in 1982 was performed at approximately 85 C for 5 days, which became the baseline aluminum dissolution process. LWO initiated a project to modify a waste tank to meet these requirements. Subsequent to an alternative evaluation, LWO management identified an opportunity to perform aluminum dissolution on sludge destined for Sludge Batch 5, but within a limited window that would not allow time for any modifications for tank heating. A variation of the baseline process, dubbed Low Temperature Aluminum Dissolution (LTAD), was developed based on the constraint of available energy input in Tank 51 and the window of opportunity, but was not constrained to a minimum extent of dissolution, i.e. dissolve as much aluminum as possible within the time available. This process was intended to operate between 55 and 70 C, but for a significantly longer time than the baseline process. LTAD proceeded in parallel with the baseline project. The preliminary evaluation at the completion of LTAD focused on the material balance and extent …

The recent discovery of superconductivity in the iron oxypnictide family of compounds1?9 has generated intense interest. The layeredcrystal structure with transition-metal ions in planar square-lattice form and the discovery of spin-density-wave order near 130 K seem to hint at a strong similarity with the copper oxide superconductors. An important current issue is the nature ofthe ground state of the parent compounds. Two distinct classes of theories, distinguished by the underlying band structure, havebeen put forward: a local-moment antiferromagnetic ground state in the strong-coupling approach, and an itinerant ground statein the weak-coupling approach. The first approach stresses onsite correlations, proximity to a Mott-insulating state and, thus, the resemblance to the high-transition-temperature copper oxides, whereas the second approach emphasizes the itinerant-electronphysics and the interplay between the competing ferromagnetic and antiferromagnetic fluctuations. The debate over the two approaches is partly due to the lack of conclusive experimental information on the electronic structures. Here wereport angle-resolved photoemission spectroscopy (ARPES) of LaOFeP (superconducting transition temperature, Tc55.9 K),the first-reported iron-based superconductor. Our results favour the itinerant ground state, albeit with band renormalization. In addition, our data reveal important differences between these and copper-based superconductors.

Foot-and-mouth disease is a highly infectious vesicular disease of cloven-hoofed animals caused by foot-and-mouth disease virus. It spreads by direct contact between animals, by animal products (milk, meat and semen), by mechanical transfer on people or fomites and by the airborne route - with the relative importance of each mechanism depending on the particular outbreak characteristics. Over the years a number of workers have developed or adapted atmospheric dispersion models to assess the risk of foot-and-mouth disease virus spread through the air. Six of these models were compared at a workshop hosted by the Institute for Animal Health/Met Office during 2008. A number of key issues emerged from the workshop and subsequent modelling work: (1) in general all of the models predicted similar directions for 'at risk' livestock with much of the remaining differences strongly related to differences in the meteorological data used; (2) determination of an accurate sequence of events is highly important, especially if the meteorological conditions vary substantially during the virus emission period; and (3) differences in assumptions made about virus release, environmental fate, and subsequent infection can substantially modify the size and location of the downwind risk area. Close relationships have now been established between participants, …
