A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the Department of Veterans Affairs (VA) paid about $3.5 billion in means-tested pension benefits to over 500,000 veterans and survivors. GAO was asked to review the management of VA pension program. This report assesses (1) the characteristics and trends in size of the current pensioner population, (2) the policies and procedures VA has in place to ensure that initial pension eligibility decisions are well managed, and (3) the procedures VA has in place to ensure that pensioners continue to receive the proper benefit payments on an ongoing basis. Our study included reviews of agency policies, procedures, and internal controls; site visits to 4 of VA's 57 regional offices and all three of its pension maintenance centers; and a selected file review of new claims at three locations."

A letter report issued by the Government Accountability Office with an abstract that begins "To help secure the nation's ports against a terrorist attack, federal regulations have required cargo and other maritime facilities to have security plans in place since July 2004. U.S Coast Guard (USCG) guidance calls for an annual inspection to ensure that plans are being followed. Federal law enacted in October 2006 required such facilities to be inspected two times a year--one of which is to be conducted unannounced. The USCG plans to conduct one announced inspection and the other as a less comprehensive unannounced "spot check." GAO examined the extent to which the USCG (1) has met inspection requirements and found facilities to be complying with their plans, (2) has determined the availability of trained personnel to meet current and future facility inspection requirements, and (3) has assessed the effectiveness of its facility inspection program and ensured that program compliance data collected and reported are reliable. GAO analyzed USCG compliance data, interviewed inspectors and other stakeholders in 7 of 35 USCG sectors of varying size, geographic location, and type of waterway."

Testimony issued by the Government Accountability Office with an abstract that begins "Information security is especially important for federal agencies, where the public's trust is essential and poor information security can have devastating consequences. Since 1997, GAO has identified information security as a governmentwide high-risk issue in each of its biennial reports to the Congress. Concerned by reports of significant weaknesses in federal computer systems, Congress passed the Federal Information Security Management Act (FISMA) of 2002, which permanently authorized and strengthened information security program, evaluation, and annual reporting requirements for federal agencies. GAO was asked to testify on the current state of federal information security and compliance with FISMA. This testimony summarizes (1) agency progress in performing key control activities, (2) the effectiveness of information security at federal agencies, and (3) opportunities to strengthen security. In preparing for this testimony, GAO reviewed prior audit reports; examined federal policies, guidance, and budgetary documentation; and analyzed agency and inspector general (IG) reports on information security."

Testimony issued by the Government Accountability Office with an abstract that begins "U.S. military forces, and ground forces in particular, have operated at a high pace since the attacks of September 11, 2001, including to support ongoing operations in Iraq and Afghanistan. Between 2001 and July 2007, approximately 931,000 U.S. Army and Marine Corps servicemembers deployed for overseas military operations, including about 312,000 National Guard or Reserve members. To support ongoing military operations and related activities, Congress has appropriated billions of dollars since 2001, and through September 2007, the Department of Defense (DOD) has reported obligating about $492.2 billion to cover these expenses, of which a large portion are related to readiness. In addition, DOD's annual appropriation, now totaling about $480 billion for fiscal year 2008, includes funds to cover readiness needs. GAO was asked to testify on (1) the readiness implications of DOD's efforts to support ongoing operations; and (2) GAO's prior recommendations related to these issues, including specific actions that GAO believes would enhance DOD's ability to manage and improve readiness. This statement is based on reports and testimonies published from fiscal years 2003 through 2008. GAO's work was conducted in accordance with generally accepted government auditing standards."

Testimony issued by the Government Accountability Office with an abstract that begins "The Subcommittee on Disability Assistance and Memorial Affairs, House Veterans' Affairs Committee, asked GAO to present its views on the Department of Veterans Affairs' (VA) disability claims process. This statement discusses (1) claims processing challenges VA faces, (2) steps VA is taking to address these challenges, and (3) opportunities for more fundamental reform. GAO has reported and testified on this subject on numerous occasions. GAO's work has addressed VA's efforts to improve the timeliness and accuracy of decisions on claims, VA's efforts to reduce pending claims levels, and concerns about decisional consistency. This testimony is based on a body of past work, updated as appropriate to reflect the current workload and initiatives."

In June 2004, the Demonstration Bulk Vitrification System (DBVS) was initiated with the intent to design, construct, and operate a full-scale bulk vitrification pilot-plant to treat low-activity tank waste from Hanford Tank 241-S-109. The DBVS facility uses In-Container Vitrification{trademark} (ICV{trademark}) at the core of the treatment process. The basic process steps combine liquid low-activity waste (LAW) and glassformers; dry the mixture; and then vitrify the mixture in a batch feed-while-melt process in a refractory lined steel container. Off-gases are processed through a state-of-the-art air pollution control system including sintered-metal filtration, thermal oxidation, acid gas scrubbing, and high-efficiency particulate air (HEPA) and high-efficiency gas adsorber (HEGA) filtration. Testing has focused on development and validation of the waste dryer, ICV, and sintered-metal filters (SMFs) equipment, operations enhancements, and glass formulation. With a parallel testing and design process, testing has allowed improvements to the DBVS equipment configuration and operating methodology, since its original inception. Design improvements include optimization of refractory panels in the ICV, simplifying glassformer addition equipment, increasing the number of waste feed chutes to the ICV, and adding capability for remote clean-out of piping, In addition, the U.S. Department of Energy (DOE) has provided an independent review of the entire DBVS …

The purpose of this report is to summarize and evaluate the Argonne Distance Tabletop Exercise (DISTEX) method. DISTEX is intended to facilitate multi-organization, multi-objective tabletop emergency response exercises that permit players to participate from their own facility's incident command center. This report is based on experience during its first use during the FluNami 2007 exercise, which took place from September 19-October 17, 2007. FluNami 2007 exercised the response of local public health officials and hospitals to a hypothetical pandemic flu outbreak. The underlying purpose of the DISTEX method is to make tabletop exercising more effective and more convenient for playing organizations. It combines elements of traditional tabletop exercising, such as scenario discussions and scenario injects, with distance learning technologies. This distance-learning approach also allows playing organizations to include a broader range of staff in the exercise. An average of 81.25 persons participated in each weekly webcast session from all playing organizations combined. The DISTEX method required development of several components. The exercise objectives were based on the U.S. Department of Homeland Security's Target Capabilities List. The ten playing organizations included four public health departments and six hospitals in the Chicago area. An extent-of-play agreement identified the objectives applicable to each …

Decomposition of the time-reversal operator for an array, or equivalently the singular value decomposition of the multistatic response matrix, has been used to improve imaging and localization of targets in complicated media. Typically, each singular value is associated with one scatterer even though it has been shown in several cases that a single scatterer can generate several singular values. In this paper we review the analysis of the time-reversal operator (TRO), or equivalently the multistatic response matrix (MRM), of an array system and a small target. We begin with two-dimensional scattering from a small cylinder then show the results for a small non-spherical target in three dimensions. We show that the number and magnitudes of the singular values contain information about target composition, shape, and orientation.

Surface display is a powerful technique that utilizes natural microbial functional components to express proteins or peptides on the cell exterior. Since the reporting of the first surface-display system in the mid-1980s, a variety of new systems have been reported for yeast, Gram-positive and Gram-negative bacteria. Non-conventional display methods are emerging, eliminating the generation of genetically modified microorganisms. Cells with surface display are used as biocatalysts, biosorbents and biostimulants. Microbial cell-surface display has proven to be extremely important for numerous applications ranging from combinatorial library screening and protein engineering to bioremediation and biofuels production.

This Nuclear Regulatory Commission (NRC) sponsored study has identified human-performance issues in new and advanced nuclear power plants. To identify the issues, current industry developments and trends were evaluated in the areas of reactor technology, instrumentation and control technology, human-system integration technology, and human factors engineering (HFE) methods and tools. The issues were organized into seven high-level HFE topic areas: Role of Personnel and Automation, Staffing and Training, Normal Operations Management, Disturbance and Emergency Management, Maintenance and Change Management, Plant Design and Construction, and HFE Methods and Tools. The issues where then prioritized into four categories using a 'Phenomena Identification and Ranking Table' methodology based on evaluations provided by 14 independent subject matter experts. The subject matter experts were knowledgeable in a variety of disciplines. Vendors, utilities, research organizations and regulators all participated. Twenty issues were categorized into the top priority category. This Brookhaven National Laboratory (BNL) technical report provides the detailed methodology, issue analysis, and results. A summary of the results of this study can be found in NUREG/CR-6947. The research performed for this project has identified a large number of human-performance issues for new control stations and new nuclear power plant designs. The information gathered in this project …

The temperature equilibration rate in dense hydrogen (for both T{sub i} > T{sub e} and T{sub i} < T{sub e}) has been calculated with large-scale molecular dynamics simulations for temperatures between 10 and 300 eV and densities between 10{sup 20}/cc to 10{sup 24}/cc. Careful attention has been devoted to convergence of the simulations, including the role of semiclassical potentials. We find that for Coulomb logarithms L {approx}> 1, Brown-Preston-Singleton [Brown et al., Phys. Rep. 410, 237 (2005)] with the sub-leading corrections and the fit of Gericke-Murillo-Schlanges [Gericke et al., PRE 65, 036418 (2003)] to the T-matrix evaluation of the collision operator, agrees with the MD data to within the error bars of the simulation. For more strongly-coupled plasmas where L {approx}< 1, our numerical results are consistent with the fit of Gericke-Murillo-Schlanges.

Purpose: To simulate the performance of a portable dual gamma and neutron identification detector array with dual directional detection capability for preliminary algorithm evaluation. Experimental procedures: Monte Carlo N-Particle (MCNP) analysis on a compact array of borated polyvinyl toluene light pipes and photomultiplier tubes, standard spectral histogramming, and directional detection capability simulations. Results: Results demonstrate that the detector system is fully capable of correcting for background variations when identifying common gamma and neutron sources while simultaneously providing source location direction estimates. Familiar anthropogenic isotopes are readily identified such as Am-241, Cs-137, Cf-252 and Co-60. Directional resolution is estimated to be within approximately 15 degrees. Specifically, all features expected for the array have been demonstrated to be credible through MCNP analysis. Conclusions: Use of this handheld dual neutron and gamma spectrometer has the promise of widespread applicability. By ultimately correlating MCNP results with empirical measurements, substantial confidence can be placed on predicting detector response to sufficiently similar spectral sources under alternate experimental configurations. Use of the detector has substantial promise for operational health physics applications.

High energy radiography capabilities are essential for many future DNT/HED experiments on NIF. We have been developing bright, high-energy (15-100 keV), high resolution (< 20 {micro}m), 1-D and 2-D radiography solutions for DNT experiments on NIF. In this LDRD, we have made significant progress utilizing high-energy, high-intensity, short-pulse lasers to generate hard K-{alpha} photons. High energy K-{alpha} sources are created by hot electrons interacting in the target fluor material after irradiation by lasers with intensity I{sub L} > 10{sup 17} W/cm{sup 2}. High resolution point projection 1-D and 2-D radiography have been achieved using {mu}-foil and {mu}-wire targets attached to low-Z substrate materials. The {mu}-wire size was 10 x 10 x 300 {micro}m on a 300 x 300 x 5 {micro}m CH substrate creating the point source size equivalent to these micro targets. This unique technique will utilize the NIF short pulse laser (ARC) as a backlighter suitable for the full range of DNT science experiments on NIF.
