A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Financial Management Improvement Act of 1996 (FFMIA) requires the 24 Chief Financial Officers (CFO) Act agencies to implement and maintain financial management systems that comply substantially with (1) federal financial management systems requirements, (2) federal accounting standards, and (3) the U.S. Government Standard General Ledger (SGL). FFMIA also requires GAO to report annually on the implementation of the act. This report, primarily based on GAO and inspectors general reports, discusses (1) the problems that continued to affect agencies systems' FFMIA compliance in fiscal year 2006 and (2) the initiatives under way to help move federal financial management toward FFMIA compliance."

A briefing report issued by the General Accounting Office with an abstract that begins "About one-third of all military service members make permanent change of station (PCS) moves each year. These moves, which may involve the members' dependents and household goods, are a considerable cost to both the government and individual service members. Not all relocation and moving costs are covered by the government. Reimbursements are based on what property a member was authorized to move and weight allowances that vary by grade and dependents. GAO found that the average duration time between PCS moves was about two years. Personnel who were unmarried and without dependents had the least time between PCS moves. Among the services, the Marine Corps had the shortest average time between PCS moves. Among enlisted personnel, those in the combat occupations had the shortest time between moves; for officers, those who were in the intelligence and tactical operations areas had the shortest average tours. GAO found that the duration of PCS tours was related to satisfaction. Those with shorter time spent between moves were less likely to be satisfied and were more likely to have a spouse who favored the member leaving the military. The most …

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Department of Defense's (DOD) family housing program. GAO discusses (1) whether DOD has implemented a standard process for determining the required military housing based on housing available in the private sector and (2) how an increase in the housing allowance is likely to affect the need for housing on military installations over the long term. Despite calls from Congress, GAO, and DOD's Inspector General, DOD has not introduced a standard process for determining military housing requirements. DOD and the services have worked to develop the framework for the process, but technical concerns, such as standards for affordable housing and commuting distance, have stalled its adoption. Increasing the housing allowance underscores the urgent need for a consistent process to determine military housing requirements because it is expected to increase demand for civilian housing and lessen the demand for military housing. From a policy standpoint, increasing the allowance better positions DOD to rely on the private sector first for housing because it removes the financial disincentive to living in civilian housing. From a management standpoint, considerable evidence suggests that it is less expensive to …

A letter report issued by the General Accounting Office with an abstract that begins "To prevent the curtailment of employment opportunities for disabled persons, the Fair Labor Standards Act allows employers to pay individuals less than the minimum wage if they have a physical or mental disability that impairs their earning or productive capacity. The Department of Labor's Wage and Hour Division (WHD) administers the special minimum wage program. More than 5,600 employers nationwide pay special wages to workers with disabilities; about 84 percent are work centers established to provide employment opportunities and support services to individuals with disabilities. Businesses comprise about 9 percent of these employers; the remaining 7 percent are hospitals or other residential care facilities and schools. Seventy-four percent of the workers paid special minimum wages by work centers have mental retardation or another developmental disability as their primary impairment, and 46 percent have multiple disabilities. From the data received by employers on the productivity of their disabled workers, it is estimated that 70 percent of the workers are less than half as productive as workers without disabilities performing the same jobs. Labor has not effectively managed the special minimum wage program to ensure that disabled workers …

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the General Services Administration's (GSA) performance report for fiscal year 2000 and its performance plan for fiscal year 2002 to assess GSA's progress in achieving key outcomes important to its mission. GAO found that some goals were met or exceeded and others were not met. For fiscal year 2002, GSA set up a strategy to better meet these goals. Overall, GSA's fiscal year 2000 performance report and fiscal year 2002 plan were more informative and useful than its report and plan from last year."

The Performance Demonstration Program (PDP) for Nondestructive Assay (NDA) is a test program designed to yield data on measurement system capability to characterize drummed transuranic (TRU) waste generated throughout the Department of Energy (DOE) complex. The tests are conducted periodically and provide a mechanism for the independent and objective assessment of NDA system performance and capability relative to the radiological characterization objectives and criteria of the Office of Characterization and Transportation (OCT). The primary documents requiring an NDA PDP are the Waste Acceptance Criteria for the Waste Isolation Pilot Plant (WAC), which requires annual characterization facility participation in the PDP, and the Quality Assurance Program Document (QAPD). This NDA PDP implements the general requirements of the QAPD and applicable requirements of the WAC. Measurement facilities must demonstrate acceptable radiological characterization performance through measurement of test samples comprised of pre-specified PDP matrix drum/radioactive source configurations. Measurement facilities are required to analyze the NDA PDP drum samples using the same procedures approved and implemented for routine operational waste characterization activities. The test samples provide an independent means to assess NDA measurement system performance and compliance per criteria delineated in the NDA PDP Plan. General inter-comparison of NDA measurement system performance among DOE …

During last twenty years, a number of models have been used to calculate the change of conductivity and dielectric strength in materials caused by the passage of high-energy photons, such as Gamma-rays and X-rays. In these models, the electromagnetic fields generated in the electronic system created by the high-energy photons have not been investigated. That is, the solution of Maxwell's equations has not been obtained for these kinds of problems. We constructed a theoretical model, described by a set of equations to solve such a problem. The model includes the equations that describe the physics of the recombination and generation of electron-hole pairs by the high-energy photons in the dielectric materials, the Compton electron generation rates, and Maxwell's equations. When a beam of gamma photons penetrates into a transmission line or cables, energetic electrons and holes (carriers) are created in the metals and dielectrics of the system by the Compton and photoelectric effects. These energetic electrons and holes in turn create many low-energy holes and electrons through the interaction of the high-energy electrons with the atoms in the solids. Since the density of the solids is very high, the mean free path of the high-energy electrons is very short. In …

Long-term changes and fluctuations in river flow, water properties, tides, and sediment transport in the Columbia River and its estuary have had a profound effect on Columbia River salmonids and their habitat. Understanding the river-flow, temperature, tidal, and sediment-supply regimes of the Lower Columbia River (LCR) and how they interact with habitat is, therefore, critical to development of system management and restoration strategies. It is also useful to separate management and climate impacts on hydrologic properties and habitat. This contract, part of a larger project led by the National Oceanic and Atmospheric Administration (NOAA), consists of three work elements, one with five tasks. The first work element relates to reconstruction of historic conditions in a broad sense. The second and third elements consist, respectively, of participation in project-wide integration efforts, and reporting. This report focuses on the five tasks within the historic reconstruction work element. It in part satisfies the reporting requirement, and it forms the basis for our participation in the project integration effort. The first task consists of several topics related to historic changes in river stage and tide. Within this task, the chart datum levels of 14 historic bathymetric surveys completed before definition of Columbia River Datum …

The New York State Energy Research and Development Authority (NYSERDA) and New York State Department of State (DOS) requested the help of DOE’s Building Energy Codes Program (BECP) in estimating the annual building energy savings and cost impacts of adopting ANSI/ASHRAE/IESNA Standard 90.1-2004 (ASHRAE 2004) requirements. This report summarizes the analysis methodology and results of energy simulation in response to that request.

We use the abundance and weak lensing mass measurements of the SDSS maxBCG cluster catalog to simultaneously constrain cosmology and the richness-mass relation of the clusters. Assuming a flat {Lambda}CDM cosmology, we find {sigma}{sub 8}({Omega}{sub m}/0.25){sup 0.41} = 0.832 {+-} 0.033 after marginalization over all systematics. In common with previous studies, our error budget is dominated by systematic uncertainties, the primary two being the absolute mass scale of the weak lensing masses of the maxBCG clusters, and uncertainty in the scatter of the richness-mass relation. Our constraints are fully consistent with the WMAP five-year data, and in a joint analysis we find {sigma}{sub 8} = 0.807 {+-} 0.020 and {Omega}{sub m} = 0.265 {+-} 0.016, an improvement of nearly a factor of two relative to WMAP5 alone. Our results are also in excellent agreement with and comparable in precision to the latest cosmological constraints from X-ray cluster abundances. The remarkable consistency among these results demonstrates that cluster abundance constraints are not only tight but also robust, and highlight the power of optically-selected cluster samples to produce precision constraints on cosmological parameters.

Radionuclide and metal contaminants are present in the badose zone and groundwater throughout the U.S. Department of Energy (DOE) legacy sites.

Thermochemical processes are being developed to provide global-scale quantities of hydrogen. A variant on sulfur-based thermochemical cycles is the Hybrid Sulfur (HyS) Process which uses a sulfur dioxide depolarized electrolyzer (SDE) to produce the hydrogen. In FY05, testing at the Savannah River National Laboratory (SRNL) explored a low temperature fuel cell design concept for the SDE. The advantages of this design concept include high electrochemical efficiency and small volumetric footprint that is crucial for successful implementation on a commercial scale. A key component of the SDE is the ion conductive membrane through which protons produced at anode migrate to the cathode and react to produce hydrogen. An ideal membrane for the SDE should have both low ionic resistivity and low sulfur dioxide transport. These features allow the electrolyzer to perform at high currents with low potentials, along with preventing contamination of both the hydrogen output and poisoning of the catalysts involved. Another key component is the electrocatalyst material used for the anode and cathode. Good electrocatalysts should be chemically stable and low overpotential for the desired electrochemical reactions. This report summarizes results from activities to evaluate different membrane and electrocatalyst materials for the SDE. Several different types of commercially-available membranes …

The calculation model was generated using the lattice physics code DRAGON. In addition, an initial comparison of calculated values to experimental measurements was performed based on preliminary results for the R1-MOX configuration.

The {approx}80 ka Lathrop Wells volcano (southern Nevada, U.S.A.) preserves evidence for a range of explosive processes and emplacement mechanisms of pyroclastic deposits and lava fields in a small-volume basaltic center. Early cone building by Strombolian bursts was accompanied by development of a fan-like lava field reaching {approx}800 m distance from the cone, built upon a gently sloping surface. Lava flows carried rafts of cone deposits, which provide indirect evidence for cone facies in lieu of direct exposures in the active quarry. Subsequent activity was of a violent Strombolian nature, with many episodes of sustained eruption columns up to a few km in height. These deposited layers of scoria lapilli and ash in different directions depending upon wind direction at the time of a given episode, reaching up to {approx}20 km from the vent, and also produced the bulk of the scoria cone. Lava effusion migrated from south to north around the eastern base of the cone as accumulation of lavas successively reversed the topography at the base of the cone. Late lavas were emplaced during violent Strombolian activity and continued for some time after explosive eruptions had waned. Volumes of the eruptive products are: fallout--0.07 km{sup 3}, scoria cone--0.02 …
