A letter report issued by the General Accounting Office with an abstract that begins "Congress established the child support enforcement program in 1975 to ensure that parents financially supported their children. State agencies administer the program and the Office of Child Support Enforcement (OCSE) in the Department of Health and Human Services oversees it. In 2002, state agencies collected over $20 billion in child support, but $657 million in collections from 2002 and previous years were undistributed--funds that were delayed or never reached families. One method used to collect child support, intercepting federal tax refunds, involves all state agencies, OCSE, and two Department of the Treasury agencies--the Internal Revenue Service (IRS) and the Financial Management Service (FMS). GAO was asked to address (1) how the total amount of undistributed collections changed over the years, (2) the causes of undistributed collections, (3) states' efforts to reduce these funds, and (4) OCSE's efforts to assist states. GAO analyzed OCSE data, administered a survey, visited 6 state agencies and interviewed officials."

A letter report issued by the General Accounting Office with an abstract that begins "Because the Occupational Safety and Health Administration (OSHA) can inspect only a fraction of 7 million U.S. worksites each year in its efforts to ensure safe and healthy working conditions, the agency has increasingly supplemented enforcement with "voluntary compliance strategies" to reach more employers and employ its resources most effectively. GAO assessed the types of strategies used, the extent of their use, and their effectiveness. GAO also obtained suggestions from specialists for additional voluntary compliance strategies."

A letter report issued by the General Accounting Office with an abstract that begins "The 21st Century Department of Justice Appropriations Authorization Act (P.L. 107-273) requires GAO to report on how investigation and arrest statistics are reported and used by federal law enforcement agencies. This report provides information on (1) the guidance and procedures followed by federal law enforcement agencies regarding counting investigations and arrests, (2) how investigation and arrest statistics are used, and (3) whether multiple agencies are counting and reporting the same investigations and arrests. GAO selected six agencies for review: the Drug Enforcement Administration (DEA), the Federal Bureau of Investigation (FBI), the former Immigration and Naturalization Service (INS), the U.S. Marshals Service, the former U.S. Customs Service, and the U.S. Postal Inspection Service (USPIS)."

A letter report issued by the General Accounting Office with an abstract that begins "In the 1990s, states sued major tobacco companies to obtain reimbursement for health impairments caused by the public's use of tobacco. In 1998, 46 states and four of the nation's largest tobacco companies signed a Master Settlement Agreement (MSA) that requires the tobacco companies to make annual payments to the states in perpetuity as reimbursement for past tobaccorelated health care costs. The MSA commits the tobacco companies to pay the states approximately $206 billion over the first 25 years. Some of the states have arranged to receive upfront proceeds based on the amounts that tobacco companies owe by issuing bonds backed by future payments. The Farm Security and Rural Investment Act of 2002 requires GAO to report annually on the amount of MSA payments states receive through fiscal year 2006. This third report provides information on the payments the 46 states received in fiscal year 2003 and expect to receive in fiscal year 2004, and states' allocations of these funds to various program categories and changes from prior years. To conduct this study, GAO surveyed the 46 states."

A letter report issued by the General Accounting Office with an abstract that begins "To protect species that are at risk for extinction, the Endangered Species Act requires that federal agencies consult with the Fish and Wildlife Service or the National Marine Fisheries Service (the Services) to ensure that activities they authorize, fund, or conduct will not jeopardize endangered species or adversely modify their critical habitat. While federal agencies recognize that consultations benefit species, some are concerned about the time and resources consumed. In this report, GAO (1) assesses the federal data on consultations, (2) identifies steps by federal agencies to improve the process, and (3) discusses lingering concerns of federal and nonfederal parties about the process. GAO limited this study to consultations with the Forest Service, the U.S. Army Corps of Engineers, and the Bureaus of Land Management and Reclamation in Idaho, Montana, Oregon, and Washington."

A chapter report issued by the General Accounting Office with an abstract that begins "Having invested billions of dollars in drinking water and wastewater infrastructure, the federal government has a major interest in protecting its investment and in ensuring that future assistance goes to utilities that are built and managed to meet key regulatory requirements. The Congress has been considering, among other things, requiring utilities to develop comprehensive asset management plans. Some utilities are already implementing asset management voluntarily. The asset management approach minimizes the total cost of buying, operating, maintaining, replacing, and disposing of capital assets during their life cycles, while achieving service goals. This report discusses (1) the benefits and challenges for water utilities in implementing comprehensive asset management and (2) the federal government's potential role in encouraging utilities to use it."

A detailed chemical kinetic mechanism has been used to simulate ignition delay times recorded by a number of experimental shock tube studies over the temperature range 900 {le} T {le} 1800 K, in the pressure range 0.75-40 atm and in the equivalence ratio range 0.5 {le} {phi} {le} 2.0. Flame speed measurements at 1 atm in the equivalence ratio range 0.4 {le} {phi} {le} 1.8 have also been simulated. Both of these data sets, particularly those recorded at high pressure, are of particular importance in validating a kinetic mechanism, as internal combustion engines operate at elevated pressures and temperatures and rates of fuel oxidation are critical to efficient system operation. Experiments in which reactant, intermediate and product species were quantitatively recorded, versus temperature in a jet-stirred reactor (JSR) and versus time in a flow reactor are also simulated. This data provide a stringent test of the kinetic mechanism as it must reproduce accurate quantitative profiles for all reactant, intermediate and product species. The JSR experiments were performed in the temperature range 1000-1110 K, in the equivalence ratio range 0.5 {le} {phi} {le} 4.0, at a pressure of 5 atm. These experiments are complemented by those carried out in a flow …

This report discusses the debate surrounding the Davis-Bacon Act (1931, as amended), which requires, among other things, that not less than the locally-prevailing wage be paid to workers employed in federal contract construction. Through recent decades, the Act has become a continuing source of contention, particularly regarding its impacts, whether it should be modified, strengthened, or repealed, and if it is being administered effectively.

We have observed stable avalanche gain in liquid argon when mixed with small amounts of xenon in the high electric field (>7 MV/cm) near the point of a chemically etched needle in a point-plane geometry. We identify two gain mechanisms, one pressure dependent, and the other independent of the applied pressure. We conclude that the pressure dependent signals are from avalanche gain in gas bubbles at the tip of the needle, while the pressure independent pulses are from avalanche gain in liquid. We measure the decay time spectra of photons from both types of avalanches. The decay times from the pressure dependent pulses decrease (increase) with the applied pressure (high voltage), while the decay times from the pressure independent pulses are approximately independent of pressure or high voltage. For our operating conditions, the collected charge distribution from avalanches is similar for 60 keV or 122 keV photon sources. With krypton additives, instead of Xe, we measure behavior consistent with only the pressure dependent pulses. Neon and TMS were also investigated as additives, and designs for practical detectors were tested.

As part of the current Saltstone Disposal Facility (SDF) Performance Assessment (PA) revision, Mechanically Stabilized Earth (MSE) vault closure cap degradation mechanisms and their impact upon filtration through the MSE vault closure cap were evaluated for the base case land use scenario (i.e. institutional control to pine forest). The degradation mechanisms evaluated included pine forest succession, erosion, and colloidal clay migration (Phifer 2003). Infiltration through the upper hydraulic barrier layer of the closure cap as determined by this evaluation will be utilized as the infiltration input to subsequent PORFLOW vadose zone contaminant transport modeling, which will also be performed as part of the PA revision.

This report assesses the feasibility of handling MST in the SWPF and ARP facility as a dry solid versus that as an aqueous slurry. MST is an inorganic sorbent material that exhibits high selectivity for strontium and actinide elements in the presence of strongly alkaline and high sodium containing salt solutions. In addition to this assessment, the effects of drying on MST properties including strontium and actinide removal performance were also tested. This work represents two of the subtasks identified in the scope of work for the DOE funded project to develop improved sorbent materials for strontium/actinide separations at SRS.

An overview is given of certain aspects of fundamental statistical theories as applied to strongly magnetized plasmas. Emphasis is given to the gyrokinetic formalism, the historical development of realizable Markovian closures, and recent results in the statistical theory of turbulent generation of long-wavelength flows that generalize and provide further physical insight to classic calculations of eddy viscosity. A Hamiltonian formulation of turbulent flow generation is described and argued to be very useful.

Recently reported numerical results for axisymmetric devices with low aspect ratio A found radial transport enhanced over the expected neoclassical value by a factor of 2 to 3. In this paper, we provide an explanation for this enhancement. Transport theory in toroidal devices usually assumes large A, and that the ratio B{sub p}/B{sub t} of the poloidal to the toroidal magnetic field is small. These assumptions result in transport which, in the low collision limit, is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device one may have B{sub p}/B{sub t} {approx} 1, and the gyroradius may be larger than the banana excursion. Here, we develop an approximate analytic transport theory valid for devices with arbitrary A. For low A, we find that the enhanced transport, referred to as omniclassical, is a combination of neoclassical and properly generalized classical effects, which become dominant in the low-A, B{sub p}/B{sub t} {approx} 1 regime. Good agreement of the analytic theory with numerical simulations is obtained.

As part of the current Saltstone Disposal Facility (SDF) Performance Assessment (PA) revision, the closure cap configuration was reevaluated and closure cap degradation mechanisms and their impact upon infiltration through the closure cap was evaluated for the existing SDF concrete vaults (i.e. vaults 1 and 4) for the base case land use scenario (i.e. institutional control to pine forest scenario) and documented in Phifer and Nelson (2003). The closure cap configuration was modified from a compacted kaolin barrier layer concept to a geosynthetic clay layer (GCL) barrier layer concept. The degradation mechanisms developed included pine forest succession, erosion, and colloidal clay migration. These degradation mechanisms resulted in changes in the hydraulic properties of the closure cap layers and resulting increases in infiltration through the closure cap over time.

The Saltstone Special Analysis calculated a limit for 14C based on the atmospheric pathway of 52 pCi/mL using some very conservative assumptions. This was compared to the estimated Low Curie Salt concentration of 0.45 pCi/mL and since the limit was two orders of magnitude greater than the estimated concentration, the decision was made that no further analysis was needed. The 14C concentration in Tank 41 has been found to be much greater than the estimated concentration and to exceed the limit derived in the Special Analysis. A rigorous analysis of the release of 14C via the air pathway that considers the chemical effects of the Saltstone system has shown that the flux of 14C is significantly less than that assumed in the Special Analysis. The net result is an inventory limit for 14C that is significantly higher than that derived in the Special Analysis that will also meet the performance objectives of DOE Order 435.1.

We present the discovery and monitoring of the optical transient (OT) associated with GRB 020410. The fading OT was found by Hubble Space Telescope (HST) observations taken 28 and 65 days after burst at a position consistent with the X-ray afterglow. Subsequent re-examination of early ground based observations revealed that a faint OT was present 6 hours after burst, confirming the source association with GRB 020410. A deep non-detection after one week requires that the OT re-brightened between day 7 and day 28, and further late time HST data taken approximately 100 days after burst imply that it is very red (F{sub nu} proportional to nu-2.7). We compare both the flux and color of the excess with supernova models and show that the data are best explained by the presence of a Type I b/c supernova at a redshift z approx. equal 0.5, which occurred roughly coincident with the day of GRB.

The Performance Assessment (PA) for the Saltstone Disposal Facility (SDF) is currently under revision. As part of the PA revision and as documented herein, the closure cap configuration has been reevaluated and closure cap degradation mechanisms and their impact upon infiltration through the closure cap have been evaluated for the institutional control to pine forest, land use scenario. This land use scenario is considered the base case land use scenario. This scenario assumes a 100-year institutional control period following final SDF closure during which the closure cap is maintained. At the end of institutional control, it is assumed that a pine forest succeeds the cap's original bamboo cover. Infiltration through the upper hydraulic barrier layer of the closure cap as determined by this evaluation will be utilized as the infiltration input to subsequent PORFLOW vadose zone contaminant transport modeling, which will also be performed as part of the PA revision. The impacts of pine forest succession, erosion, and colloidal clay migration as degradation mechanisms on the hydraulic properties of the closure cap layers over time have been estimated and the resulting infiltration through the closure cap has been evaluated. The primary changes caused by the degradation mechanisms that result in …
