For more than a century, the federal government has constructed water resource projects for a variety of purposes, including flood control, navigation, power generation, and irrigation. While most municipal and industrial water supplies have been built by non-federal entities, most of the large, federal water supply projects in the West, including Hoover and Grand Coulee dams, were constructed by the Bureau of Reclamation (Department of the Interior) to provide water for irrigation.

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2004, lenders made about $65 billion in loans through the Federal Family Education Loan Program (FFELP) to assist students in paying for postsecondary education. The Higher Education Act (HEA), which authorizes FFELP, broadly defined eligible lenders--including schools. The Department of Education's (Education) Office of Federal Student Aid (FSA) is responsible for ensuring that lenders comply with FFELP laws and regulations. Recently, schools have become increasingly interested in becoming lenders, and this has raised concerns about whether it is appropriate for schools to become lenders given that they both determine students' eligibility for loans and in some cases set the price of attendance. In light of these concerns we determined (1) the extent to which schools have participated as FFELP lenders and their characteristics, (2) how schools have structured lending operations and benefits for borrowers and schools, and (3) statutory and regulatory safeguards designed to protect taxpayers' and borrowers' interests."

A letter report issued by the Government Accountability Office with an abstract that begins "Mobility is critical to the nation's economy. Projections of future passenger and freight travel suggest that increased levels of investment may be needed to maintain the current levels of mobility provided by the nation's highway and transit systems. However, calls for greater investment in transportation come amid growing concerns about fiscal imbalances at all levels of the government. As a result, careful decisions will need to be made to ensure that transportation investments maximize the benefits of each federal dollar invested. In this report GAO identifies (1) the categories of benefits and costs that can be attributed to new highway and transit investments and the challenges in measuring them; (2) how state, local, and regional decision makers consider the benefits and costs of new highway and transit investments when comparing alternatives; (3) the extent to which investments meet their projected outcomes; and (4) options to improve the information available to decision makers. To address these objectives, we convened an expert panel, surveyed state departments of transportation and transit agencies, and conducted site visits to five metropolitan areas that had both a capacity-adding highway project and transit …

This report examines what we currently know about preprimary programs, including numbers of children served and their family characteristics; as well as data on the efficacy of preprimary programs in enhancing later learning and other life skills. Current federal programs that serve preschool age children are described, and policy issues which may arise as the federal role in early childhood education is debated are discussed.

Amorphous SiO{sub 2} is classically understood as a continuous random network forming glass. Typically amorphous materials possess no translational symmetry, which is the signature of a crystal. Our interest in investigating SiO{sub 2}, grown as a thin film (100, 500 {angstrom}) on Si(001), is to observe how this particular amorphous phase is able to couple to the crystalline substrate and reflect a peculiar degree of order.

Cleanup at the Savannah River Site brings with it the need to clean out and close down the radioactive waste tanks constructed in support of the fuel rod dissolution process. An innovative technique for assaying waste tanks has been developed at the Savannah River Site. The technique uses a gamma detector in the annular space between the inner and outer tank walls of double walled tanks. Unique shielding, counting electronics, and deployment techniques were developed. The system provides information to facilitate mapping interstitial liquid levels, sludge layers and other structures in the waste tank located near the tank walls. The techniques used, results, and lessons learned will be discussed.

Predictions of increasing levels of anthropogenic carbon dioxide (CO{sub 2}) and the specter of global warming have intensified research efforts to identify ways to sequester carbon. A number of novel avenues of research are being considered, including bioprocessing methods to promote and accelerate biosequestration of CO{sub 2} from the environment through the growth of organisms such as coccolithophorids, which are capable of sequestering CO{sub 2} relatively permanently. Calcium and magnesium carbonates are currently the only proven, long-term storage reservoirs for carbon. Whereas organic carbon is readily oxidized and releases CO{sub 2} through microbial decomposition on land and in the sea, carbonates can sequester carbon over geologic time scales. This proposal investigates the use of coccolithophorids ? single-celled, marine algae that are the major global producers of calcium carbonate ? to sequester CO{sub 2} emissions from power plants. Cultivation of coccolithophorids for calcium carbonate (CaCO{sub 3}) precipitation is environmentally benign and results in a stable product with potential commercial value. Because this method of carbon sequestration does not impact natural ecosystem dynamics, it avoids controversial issues of public acceptability and legality associated with other options such as direct injection of CO{sub 2} into the sea and ocean fertilization. Consequently, cultivation of …

In this work, using atomic force microscopy and scanning tunneling microscopy, we study the surface morphologies of epitaxial InN films grown by plasma-assisted molecular beam epitaxy with intervening GaN buffer layers on sapphire substrates. On smooth GaN buffer layers, nucleation and evolution of three-dimensional InN islands at various coverages and growth temperatures are investigated. The shapes of the InN islands are observed to be predominantly mesa-like with large flat (000-1) tops, which suggests a possible role of indium as a surfactant. Rough GaN buffer layers composed of dense small GaN islands are found to significantly improve uniform InN wetting of the substrates, on which atomically smooth InN films are obtained that show the characteristics of step-flow growth. Scanning tunneling microscopy imaging reveals the defect-mediated surface morphology of smooth InN films, including surface terminations of screw dislocations and a high density of shallow surface pits with depths less than 0.3 nm. The mechanisms of the three-dimensional island size and shape evolution and formation of defects on smooth surfaces are considered.

In order to reduce recirculating power fraction to acceptable levels, the spherical torus concept relies on the simultaneous achievement of high toroidal {beta} and high bootstrap fraction in steady state. In the last year, as a result of plasma control system improvements, the achievable plasma elongation on the National Spherical Torus Experiment (NSTX) has been raised from {kappa} {approx} 2.1 to {kappa} {approx} 2.6--approximately a 25% increase. This increase in elongation has lead to a doubling increase in the toroidal {beta} for long-pulse discharges. The increase in {beta} is associated with an increase in plasma current at nearly fixed poloidal {beta}, which enables higher {beta}{sub t} with nearly constant bootstrap fraction. As a result, for the first time in a spherical torus, a discharge with a plasma current of 1 MA has been sustained for 1 second. Data is presented from NSTX correlating the increase in performance with increased plasma shaping capability. In addition to improved shaping, H-modes induced during the current ramp phase of the plasma discharge have been used to reduce flux consumption during and to delay the onset of MHD instabilities. A modeled integrated scenario, which has 100% non-inductive current drive with very high toroidal {beta}, will …

The Department of Energy's Hanford Nuclear Site located in Washington State has accumulated over 2 million curies of radioactive waste from activities related to the production of plutonium (Ahearne, 1997). Sixty-seven of the single-shelled tanks located at the site are thought to have leaked, allowing between 2 and 4 million liters of waste fluids into the underlying vadose zone. The chemical processes employed at the Hanford Site to extract plutonium, as well as the need to minimize corrosion of the high-carbon steel storage tanks, resulted in uncharacterized hyperalkaline waste streams rich in radionuclides as well as other species including significant amounts of sodium and aluminum.

The Health Insurance Portability and Accountability Act of 1996 guarantees the availability and renewability of health insurance coverage for certain individuals. It permits a limited number of small businesses and self-employment individuals to establish tax-favored medical savings accounts, increases the tax deduction for health insurance for the self-employed, and amends the Internal Revenue Code to treat private long-term care policies the way health insurance policies and health care expenses are currently treated.

With the dramatic population increase in the West over the last thirty years, the Western states have been under increasing pressure from their citizens to secure future access to water. In planning to meet this goal, however, Western officials have had to confront a heretofore obscure doctrine of water law: the doctrine of Indian reserved water rights, also known as the Winters doctrine. Therefore, in order for Western water officials to effectively plan for a stable allocation of water on which all parties can rely, they must find a way to satisfy the water claims of local Indian tribes. This report provides an overview of the legal issues surrounding Indian reserved water rights disputes.
