Unusual magnetic quantum oscillations in organic metals at high magnetic fields
The authors report on Shubnikov-de Haas (SdH) and de Haas-van Alphen (dHvA) results for the highly two-dimensional (2D) organic superconductors {kappa}-(ET){sub 2}I{sub 3} ({Tc} = 3.5 K) and {beta}{double_prime}-(ET){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3} ({Tc} = 4.4 K). The SdH oscillations of both materials show an apparent deviation from the well-understood 2D dHvA signal at low temperatures and high magnetic fields. For {kappa}-(ET){sub 2}I{sub 3}, the mechanism leading to this behavior still needs to be clarified. For {beta}{double_prime}-(ET){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3}, an anomalous steady background part of the magnetoresistance seems to account for the observed discrepancies.

USING WET AIR OXIDATION TECHNOLOGY TO DESTROY TETRAPHENYLBORATE
A bench-scale feasibility study on the use of a Wet Air Oxidation (WAO) process to destroy a slurry laden with tetraphenylborate (TPB) compounds has been undertaken. WAO is an aqueous phase process in which soluble and/or insoluble waste constituents are oxidized using oxygen or oxygen in air at elevated temperatures and pressures ranging from 150 C and 1 MPa to 320 C and 22 MPa. The products of the reaction are CO{sub 2}, H{sub 2}O, and low molecular weight oxygenated organics (e.g. acetate, oxalate). Test results indicate WAO is a feasible process for destroying TPB, its primary daughter products [triphenylborane (3PB), diphenylborinic acid (2PB), and phenylboronic acid (1PB)], phenol, and most of the biphenyl byproduct. The required conditions are a temperature of 300 C, a reaction time of 3 hours, 1:1 feed slurry dilution with 2M NaOH solution, the addition of CuSO{sub 4}.5H{sub 2}O solution (500 mg/L Cu) as catalyst, and the addition of 2000 mL/L of antifoam. However, for the destruction of TPB, its daughter compounds (3PB, 2PB, and 1PB), and phenol without consideration for biphenyl destruction, less severe conditions (280 C and 1-hour reaction time with similar remaining above conditions) are adequate.

VA Information Technology: Important Initiatives Begun, Yet Serious Vulnerabilities Persist
Testimony issued by the General Accounting Office with an abstract that begins "Although the Department of Veterans' Affairs (VA) has taken actions to improve many of its information technology (IT) management processes, it continues to face substantive challenges that, if left incomplete, could disrupt existing progress and threaten the viability of its existing and future IT spending. VA has yet to fill its full-time department chief information officer vacancy since the position's creation three years ago. In addition, sustained leadership and commitment are necessary to improve VA's departmentwide computer security program, especially as VA begins to move some of its information and services to veterans onto the Internet. And although VA has done a good job of posting privacy and security notices on its websites, it should focus more attention on complying with Office of Management and Budget policies prohibiting the use of persistent cookies. Furthermore, until VA defines and begins to implement a departmentwide, enterprise architecture, it will continue to encounter costly difficulties in achieving its "One VA" vision. Finally, VA faces important decisions on making greater use of the Decision Support System and on the continued development and wide-scale implementation of the compensation and pension replacement project. Continued …

Validation of a Gamma Spectrometric Method for the Measurement of {sup 226,228}Ra in Environmental Media Relevant to the Offshore Oil and Gas Industry
The offshore production of oil and gas leads to naturally occurring {sup 226,228}Ra being brought to the surface along with produced water. Assessment of potential environmental exposures, if any, requires accurate, precise and practical methods for the measurement of low concentrations of {sup 226,228}Ra. A method for the simultaneous measurement of {sup 226,228}Ra in marine sediments, biota and produced water at a sensitivity of 0.01 pCi/g using high-sensitivity, high-resolution gamma spectrometry was subjected to an interlaboratory exercise using U.S. commercial laboratories to validate its accuracy, precision, robustness, and sample throughput. The prescribed method involves direct counting for solid samples and a simple Pb({sup 133}Ba,Ra)SO{sub 4} co-precipitation procedure for water samples followed by gamma counting. Analytical results received from the participating laboratories were subjected to data analysis and statistical evaluation to validate the overall performance of the prescribed method. Relatively good precision and high accuracy of data were achieved when the participating laboratories followed the prescribed procedure closely. The consistency of results among laboratories was not correlated to the {sup 226,228}Ra concentrations in the samples. Most of the results that failed the acceptance criteria were either due to the absence of geometric and secular equilibrium between {sup 226}Ra and its signature …

Value-Added Taxes: Lessons Learned from Other Countries on Compliance Risks, Administrative Costs, Compliance Burden, and Transition
A letter report issued by the Government Accountability Office with an abstract that begins "Dissatisfaction with the federal tax system has led to a debate about U.S. tax reform, including proposals for a national consumption tax. One type of proposed consumption tax is a value-added tax (VAT), widely used around the world. A VAT is levied on the difference between a business's sales and its purchases of goods and services. Typically, a business calculates the tax due on its sales, subtracts a credit for taxes paid on its purchases, and remits the difference to the government. While the economic and distributional effects of a U.S. VAT type tax have been studied, GAO was asked to identify the lessons learned from other countries' experiences in administering a VAT. This report describes (1) how VAT design choices, such as exemptions and enforcement mechanisms, have affected compliance, administrative costs, and compliance burden; (2) how countries with federal systems administer a VAT; and (3) how countries that recently transitioned to a VAT implemented the new tax. GAO selected five countries to study--Australia, Canada, France, New Zealand, and the United Kingdom--that provided a range of VAT designs from relatively simple to more complex with multiple …

Wildland Fires: Better Information Needed on Effectiveness of Emergency Stabilization and Rehabilitation Treatments
A letter report issued by the General Accounting Office with an abstract that begins "Wildfires burn millions of acres annually. Most burnt land can recover naturally, but a small percentage needs short-term emergency treatment to stabilize burnt land that threatens public safety, property, or ecosystems or longer-term treatments to rehabilitate land unlikely to recover naturally. The Department of the Interior (Interior) and the Department of Agriculture's (USDA's) Forest Service--the two departments that manage most federal land--spend millions of dollars annually on such treatments. GAO was asked to (1) describe the two departments' processes for implementing their programs, (2) identify the costs and types of treatments implemented, and (3) determine whether these treatments are effective."

Workforce Investment Act of 1998 (WIA): Reauthorization of Title I Job Training Programs
Title I of the Workforce Investment Act of 1998 (WIA) (P.L. 105-220), the country’s chief job training legislation, authorizes several job training programs, including Youth, Adult, and Dislocated Worker Activities; Job Corps; Youth Opportunity Grants; and programs for Native Americans, migrant and seasonal farmworkers, and veterans. The funding authorization for WIA programs expires on September 30,2003. On March 6, 2003, the Administration released its proposal for reauthorization of the Title I programs. On March 27, 2003, the House Committee on Education and the Workforce approved H.R. 1261, as amended, the Workforce Reinvestment and Adult Education Act of 2003. In addition to reauthorizing the Title I job training programs, the bill would also reauthorize the adult education and literacy programs and the Rehabilitation Act of 1973. This report focuses on provisions related to the Title I programs.
