A letter report issued by the Government Accountability Office with an abstract that begins "More than 10,000 U.S. military servicemembers, including National Guard and Reserve members, have been injured in the conflicts in Afghanistan and Iraq. Those with serious injuries are likely to be discharged from the military and return to civilian life with disabilities. The Department of Veterans Affairs (VA) offers vocational rehabilitation and employment (VR&E) services to help these injured servicemembers in their transition to civilian employment. GAO has noted that early intervention--the provision of rehabilitation services as soon as possible after the onset of a disability--is a practice that significantly facilitates the return to work. GAO examined how VA expedites VR&E services to seriously injured servicemembers and the challenges VA faces in its efforts to do so."

A letter report issued by the Government Accountability Office with an abstract that begins "A high-performance organization relies on a dynamic workforce with the requisite talents, multidisciplinary knowledge, and up-to-date skills to ensure that it is equipped to accomplish its mission and achieve its goals. Such organizations typically (1) foster a work environment in which people are enabled and motivated to contribute to mission accomplishment and (2) provide both accountability and fairness for all employees. To accomplish these objectives, high-performance organizations are inclusive, drawing on the strengths of employees at all levels and of all backgrounds--an approach consistent with diversity management. For purposes of our review, diversity management is defined as a process intended to create and maintain a positive work environment where the similarities and differences of individuals are valued, so that all can reach their potential and maximize their contributions to an organization's strategic goals and objectives. As part of a request that GAO report on the federal government's performance in managing its diverse workforce, GAO was asked to identify (1) leading diversity management practices and (2) examples of the identified practices in the federal government. This report contains no recommendations."

A letter report issued by the Government Accountability Office with an abstract that begins "By deploying armed air marshals onboard selected flights, the Federal Air Marshal Service (FAMS), a component of the Transportation Security Administration (TSA), plays a key role in helping to protect approximately 29,000 domestic and international flights operated daily by U.S. air carriers. GAO was asked to examine (1) FAMS's operational approach or "concept of operations" for covering flights, (2) to what extent this operational approach has been independently evaluated, and (3) the processes and initiatives FAMS established to address workforce-related issues. GAO analyzed documented policies and procedures regarding FAMS's operational approach and a July 2006 classified report based on an independent evaluation of that approach. Also, GAO analyzed employee working group reports and other documentation of FAMS's processes and initiatives for addressing workforce-related issues, and interviewed the FAMS Director, other senior officials, and 67 air marshals (selected to reflect a range in levels of experience). This report is the public version of a restricted report (GAO-09-53SU) issued in December 2008."

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past two decades, the number of acres burned by wildland fires has surged, often threatening human lives, property, and ecosystems. Past management practices, including a concerted federal policy in the 20th century of suppressing fires to protect communities and ecosystem resources, unintentionally resulted in steady accumulation of dense vegetation that fuels large, intense, wildland fires. While such fires are normal in some ecosystems, in others they can cause catastrophic damage to resources as well as to communities near wildlands known as the wildland-urban interface. In 1999, GAO recommended that the Forest Service develop a cohesive strategy for responding to wildland fire threats. As a follow-up, 5 years later, GAO was asked to identify the (1) progress the federal government has made in responding to wildland fire threats and (2) challenges it will need to address within the next 5 years."

A letter report issued by the Government Accountability Office with an abstract that begins "Seaports are a critical vulnerability in the nation's defense against terrorism. They are potential entry points for bombs or other devices smuggled into cargo ships and ports' often-sprawling nature presents many potential targets for attack. To assess the response procedures that would be implemented in an attack or security incident, officials conduct port-specific exercises. Many federal, state, and local agencies may potentially be involved. The Coast Guard has primary responsibility for coordinating these exercises and analyzing the results. GAO examined (1) the emerging framework for coordinating entities involved in security responses, (2) legal and operational issues emerging from exercises conducted to date, and (3) Coast Guard management of reports analyzing exercises. GAO reviewed reports on 82 exercises from fiscal year 2004 and observed 4 exercises as they were being conducted."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Strategy for Homeland Security sets forth a plan to improve homeland security through the cooperation of federal, state, local, and private sector organizations on an array of functions. These functions are organized into the six distinct "critical mission areas" of (1) intelligence and warning, (2) border and transportation security, (3) domestic counterterrorism, (4) protecting critical infrastructures and key assets, (5) defending against catastrophic threats, and (6) emergency preparedness and response. Within each of these mission areas, the strategy identifies "major initiatives" to be addressed. In all, the strategy cites 43 initiatives across the six mission areas. GAO reviewed the strategy's implementation to (1) determine whether its initiatives are being addressed by key departments' strategic planning and implementation activities, whether the initiatives have lead agencies identified for their implementation, and whether the initiatives were being implemented in fiscal year 2004 by such agencies and (2) identify ongoing homeland security challenges that have been reflected in GAO products since September 11, 2001, by both mission area and issues that cut across mission areas."

Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Pricewaterhouse Coopers (PwC) report on the actuarial projections for the trust funds of the Old Age, Survivors, and Disability Insurance programs, focusing on whether the Social Security Administration's (SSA) Board of Trustees': (1) 1999 long-range intermediate actuarial projections--their best estimates--as presented in the Trustees' 1999 report are based on generally accepted actuarial methods and techniques and include economic and demographic assumptions that contain no material defects because of errors or omissions and are individually reasonable; and (2) sensitivity tests include all assumptions that could have a significant effect on the projections and are reasonable."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Autism Society of America, about 1.5 million Americans are currently living with some form of autism. This figure includes over 100,000 school-aged children diagnosed with autism served under the Individuals with Disabilities Education Act (IDEA), the primary federal legislation that addresses the educational needs of children with disabilities. As the number of children diagnosed with autism has increased, interest in understanding how children diagnosed with autism are being served under IDEA has grown. In this report we are describing the tend in the number of children diagnosed with autism served under IDEA, the services provided to these children, the estimated per pupil expenditures for educating children with autism, and approaches to their education."

A letter report issued by the General Accounting Office with an abstract that begins "Over 25 million children have health insurance coverage through Medicaid or the State Children's Health Insurance Program (SCHIP). Coverage alone, however, does not guarantee that services will be available or that children will receive needed care. GAO was asked to evaluate states' efforts to facilitate and monitor access to primary and preventive services for children in these jointly funded federal-state programs. The study surveyed 16 states, covering over 65 percent of the Medicaid and SCHIP population. GAO analyzed requirements relevant to managed care and fee-for-service (FFS) delivery systems, including the number and location of physicians and their availability to see beneficiaries, monitoring of health plan or physician compliance with these requirements, and collection and analysis of beneficiary service utilization data."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's January 8, 2009, report that provides a framework for modernizing the outdated U.S. financial regulatory system. GAO prepared this work under the authority of the Comptroller General to help policymakers weigh various regulatory reform proposals and consider ways in which the current regulatory system could be made more effective and efficient. This testimony (1) describes how regulation has evolved in banking, securities, thrifts, credit unions, futures, insurance, secondary mortgage markets and other important areas; (2) describes several key changes in financial markets and products in recent decades that have highlighted significant limitations and gaps in the existing regulatory system; and (3) presents an evaluation framework that can be used by Congress and others to shape potential regulatory reform efforts."

Correspondence issued by the General Accounting Office with an abstract that begins "GAO provided information on the Federal Housing Administration's credit subsidy budget estimates used to formulate the President's fiscal year (FY) 2000 budget to determine whether: (1) these estimates were reasonable; and (2) any changes need to be made to the credit subsidy estimation process to ensure that future budget estimates are reasonable."

A linear CKM relation, {bar {eta}} = tan {Phi}{sub 3/2}({bar p} - 0.24 {+-} 0.03), involving a 1{sigma} range for {Phi}{sub 3/2}, 20{sup o} < {Phi}{sub 3/2} < 115{sup o}, is obtained from B{sup 0} {yields} K*{pi} amplitudes measured recently in Dalitz plot analyses of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} and B{sup 0}(t) {yields} K{sub S}{pi}{sup +}{pi}{sup -}. This relation is consistent within the large error on {Phi}{sub 3/2} with other CKM constraints which are unaffected by new b {yields} s{bar q}q operators. Sensitivity of the method to a new physics contribution in the {Delta}S = {Delta}I = 1 amplitude is discussed.

Presentation on the results from the DOE fuel cell bus evaluation given at the Transportation Research Board's 87th annual meeting, January 14, 2008.

The purpose of this Cooperative Research and Development Agreement (CRADA) was to explore and develop advanced manufacturing techniques to fabricate sintered iron-aluminide intermetallic porous bodies used for gas filtration so as to reduce production costs while maintaining or improving performance in advanced coal gasification and combustion systems. The use of a power turbine fired with coal-derived synthesis gas requires some form of gas cleaning in order to protect turbine and downstream components from degradation by erosion, corrosion, and/or deposition. Hot-gas filtration is one form of cleaning that offers the ability to remove particles from the gases produced by gasification processes without having to substantially cool and, possibly, reheat them before their introduction into the turbine. This technology depends critically on materials durability and reliability, which have been the subject of study for a number of years.

The SRS sludge that was to become a major fraction of Sludge Batch 5 (SB5) for the Defense Waste Processing Facility (DWPF) contained a large fraction of H-Modified PUREX (HM) sludge, containing a large fraction of aluminum compounds that could adversely impact the processing and increase the vitrified waste volume. It is beneficial to reduce the non-radioactive fraction of the sludge to minimize the number of glass waste canisters that must be sent to a Federal Repository. Removal of aluminum compounds, such as boehmite and gibbsite, from sludge can be performed with the addition of NaOH solution and heating the sludge for several days. Preparation of SB5 involved adding sodium hydroxide directly to the waste tank and heating the contents to a moderate temperature through slurry pump operation to remove a fraction of this aluminum. The Savannah River National Laboratory (SRNL) was tasked with demonstrating this process on actual tank waste sludge in our Shielded Cells Facility. This paper evaluates some of the impacts of aluminum dissolution on sludge washing and DWPF processing by comparing sludge processing with and without aluminum dissolution. It was necessary to demonstrate these steps to ensure that the aluminum removal process would not adversely impact …

NanoDynamics Inc. has undertaken a study to develop and demonstrate an anode-supported solid oxide fuel cell capable of generating a minimum of 20 W per cell on hydrogen. The cell technology will also be assed for operation on renewable hydrocarbon-based fuels such as biomass gas, as well its applicability for larger-scale power production. The project was divided into five sub-tasks, the first of which was the development and refinement of the cell manufacturing processes of gel-casting and paste extrusion for the fabrication of planar and tubular anode supports. These methods exhibited high production yields with excellent reproducibility. Using a conventional YSZ-based cell as a performance benchmark, new materials-sets and cell configurations were developed. Three prototype configurations were implemented, the best generating an average of 10 W per cell, and exhibiting excellent potential for further development and scale-up. Using a variety of techniques such as modifying the materials-set, microstructure, and cell configuration, cells with an average power output of 22.7 W were demonstrated, 13.5% in excess of the 20 W project goal. Thermal cycling was performed on such cells, and it was found that over a regime of 150 cycles (approximately 300 h), the cell power increased by 1.8%. So-called “short-stacks” …

Transverse-spin physics has been very active and rapidly developing in the last few years. In this talk, I will briefly summarize recent theoretical developments, focusing on the associated QCD dynamics in transverse spin physics.

Forecasts of available wind energy resources at high spatial resolution enable users to site wind turbines in optimal locations, to forecast available resources for integration into power grids, to schedule maintenance on wind energy facilities, and to define design criteria for next-generation turbines. This array of research needs implies that an appropriate forecasting tool must be able to account for mesoscale processes like frontal passages, surface-atmosphere interactions inducing local-scale circulations, and the microscale effects of atmospheric stability such as breaking Kelvin-Helmholtz billows. This range of scales and processes demands a mesoscale model with large-eddy simulation (LES) capabilities which can also account for varying atmospheric stability. Numerical weather prediction models, such as the Weather and Research Forecasting model (WRF), excel at predicting synoptic and mesoscale phenomena. With grid spacings of less than 1 km (as is often required for wind energy applications), however, the limits of WRF's subfilter scale (SFS) turbulence parameterizations are exposed, and fundamental problems arise, associated with modeling the scales of motion between those which LES can represent and those for which large-scale PBL parameterizations apply. To address these issues, we have implemented significant modifications to the ARW core of the Weather Research and Forecasting model, including the …

The long-term goal of DOE’s Commercial Buildings Integration subprogram is to develop cost-effective technologies and building practices that will enable the design and construction of net Zero Energy Buildings — commercial buildings that produce as much energy as they use on an annual basis — by 2025. To support this long-term goal, DOE further called for — as part of its FY07 Statement of Needs — the development by 2010 of “five cost-effective design technology option sets using highly efficient component technologies, integrated controls, improved construction practices, streamlined commissioning, maintenance and operating procedures that will make new and existing commercial buildings durable, healthy and safe for occupants.” In response, PNNL proposed and DOE funded a scoping study investigation of one such technology option set, low-lift cooling, that offers potentially exemplary HVAC energy performance relative to ASHRAE Standard 90.1-2004. The primary purpose of the scoping study was to estimate the national technical energy savings potential of this TOS.

This report documents a detailed buckling evaluation of the primary tanks in the Hanford double-shell waste tanks (DSTs), which is part of a comprehensive structural review for the Double-Shell Tank Integrity Project. This work also provides information on tank integrity that specifically responds to concerns raised by the Office of Environment, Safety, and Health (ES&H) Oversight (EH-22) during a review of work performed on the double-shell tank farms and the operation of the aging waste facility (AWF) primary tank ventilation system. The current buckling review focuses on the following tasks: (1) Evaluate the potential for progressive anchor bolt failure and the appropriateness of the safety factors that were used for evaluating local and global buckling. The analysis will specifically answer the following questions: (a) Can the EH-22 scenario develop if the vacuum is limited to -6.6-inch water gage (w.g.) by a relief valve? (b) What is the appropriate factor of safety required to protect against buckling if the EH-22 scenario can develop? (c) What is the appropriate factor of safety required to protect against buckling if the EH-22 scenario cannot develop? (2) Develop influence functions to estimate the axial stresses in the primary tanks for all reasonable combinations of tank …

Beryllium has been used widely in specific areas of nuclear technology. Frequent monitoring of air and possible contaminated surfaces in U.S Department of Energy (DOE) facilities is required to identify potential health risks and to protect DOE workers from beryllium-contaminated dust. A new method has been developed to rapidly remove spectral interferences prior to beryllium (Be) measurement by inductively-coupled plasma atomic emission spectrometry (ICP-AES). The ion exchange separation removes uranium (U), thorium (Th), niobium (Nb), vanadium (V), molybdenum (Mo), zirconium (Zr), tungsten (W), iron (Fe), chromium (Cr), cerium (Ce), erbium (Er) and titanium (Ti). A stacked column consisting of Diphonix Resin{reg_sign} and TEVA Resin{reg_sign} reduces the levels of the spectral interferences so that low level Be measurements can be performed accurately. If necessary, an additional anion exchange separation can be used for further removal of interferences, particularly chromium. The method has been tested using spiked filters, spiked wipe samples and certified reference material standards with high levels of interferences added. The method provides very efficient removal of spectral interferences with very good accuracy and precision for beryllium on filters or wipes. A vacuum box system is employed to reduce analytical time and reduce labor costs.

The design, construction, and performance of a linear radio-frequency ion trap (RFQ) intended for use in the Enriched Xenon Observatory (EXO) are described. EXO aims to detect the neutrinoless double-beta decay of {sup 136}Xe to {sup 136}Ba. To suppress possible backgrounds EXO will complement the measurement of decay energy and, to some extent, topology of candidate events in a Xe filled detector with the identification of the daughter nucleus ({sup 136}Ba). The ion trap described here is capable of accepting, cooling, and confining individual Ba ions extracted from the site of the candidate double-beta decay event. A single trapped ion can then be identified, with a large signal-to-noise ratio, via laser spectroscopy.

Harris, Song and Kiang [1] (HSK) describe their results on reconstructing the free energy profiles for both the stretch of the titin polymer, and the unfolding of an individual I27 domain. The new finding reported in [1] is the measurement of the free energy barrier (or activation energy) to unfolding the I27 domain. Due to a misinterpretation of the mechanics involved, the free energy surface (and thus the energy barrier) to unfolding the I27 domain was not measured.
