Testimony issued by the Government Accountability Office with an abstract that begins "The federal government currently relies heavily on the individual income tax and payroll taxes for about 80 percent of its total annual revenue. Long-range projections show that without some form of policy change, the gap between revenues and spending will increasingly widen. The debate about the future tax system is partly about whether the goals for the nation's tax system can be best achieved by reforming the current income tax so that it has a broader base and flatter rate schedule, or switching to some form of consumption tax. This testimony reviews the revenue contribution of the current individual income tax as well as its complexity, economic efficiency, equity, and taxpayer compliance issues; discusses some common dimensions to compare tax proposals; and draws some conclusions for tax reform. This statement is based on previously published GAO work and reviews of relevant literature."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) bears sole responsibility for eight DOD-specific high-risk areas and shares responsibility for six governmentwide high-risk areas. These high-risk areas reflect the pervasive weaknesses that cut across all of DOD's major business operations. Several of the high-risk areas are inter-related, including, but not limited to, financial management, business systems modernization, and DOD's overall approach to business transformation. Billions of dollars provided to DOD are wasted each year because of ineffective performance and inadequate accountability. DOD has taken some positive steps to successfully transform its business operations and address these high-risk areas, but huge challenges remain. This testimony discusses (1) pervasive, long-standing financial and business management weaknesses that affect DOD's efficiency; (2) some examples that highlight a need for improved business systems development and implementation oversight; (3) DOD's key initiatives to improve financial management, related business processes, and systems; and (4) actions needed to enhance the success of DOD's financial and business transformation efforts."

Characterizing percolation patterns in unsaturated fractured rock has posed a greater challenge to modeling investigations than comparable saturated zone studies, because of the heterogeneous nature of unsaturated media and the great number of variables impacting unsaturated flow. This paper presents an integrated modeling methodology for quantitatively characterizing percolation patterns in the unsaturated zone of Yucca Mountain, Nevada, a proposed underground repository site for storing high-level radioactive waste. The modeling approach integrates a wide variety of moisture, pneumatic, thermal, and isotopic geochemical field data into a comprehensive three-dimensional numerical model for modeling analyses. It takes into account the coupled processes of fluid and heat flow and chemical isotopic transport in Yucca Mountain's highly heterogeneous, unsaturated fractured tuffs. Modeling results are examined against different types of field-measured data and then used to evaluate different hydrogeological conceptualizations and their results of flow patterns in the unsaturated zone. In particular, this model provides a much clearer understanding of percolation patterns and flow behavior through the unsaturated zone, both crucial issues in assessing repository performance. The integrated approach for quantifying Yucca Mountain's flow system is demonstrated to provide a practical modeling tool for characterizing flow and transport processes in complex subsurface systems.

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 {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 …
