Over the past two years, Arizona Public Service, a subsidiary of Pinnacle West Capital Corporation, in cooperation with the U.S. Department of Energy's Advanced Vehicle Testing Activity, tested four gaseous fuel vehicles as part of its alternative fueled vehicle fleet. One vehicle operated initially using compressed natural gas (CNG) and later a blend of CNG and hydrogen. Of the other three vehicles, one was fueled with pure hydrogen and two were fueled with a blend of CNG and hydrogen. The three blended-fuel vehicles were originally equipped with either factory CNG engines or factory gasoline engines that were converted to run CNG fuel. The vehicles were variously modified to operate on blended fuel and were tested using 15 to 50% blends of hydrogen (by volume). The pure-hydrogen-fueled vehicle was converted from gasoline fuel to operate on 100% hydrogen. All vehicles were fueled from the Arizona Public Service's Alternative Fuel Pilot Plant, which was developed to dispense gaseous fuels, including CNG, blends of CNG and hydrogen, and pure hydrogen with up to 99.9999% purity. The primary objective of the test was to evaluate the safety and reliability of operating vehicles on hydrogen and blended fuel, and the interface between the vehicles and …

This report discusses President Bush's 2002 requests for new funding and additional authority to provide assistance to Colombia and six regional neighbors in a continuation of the Andean Regional Initiative (ARI) launched in 2001.

Photographic inspection techniques have become technically more sophisticated in recent years with the development of advanced equipment for the mass consumer market. High quality digital cameras, for example, are now available around the world. Combined with an appropriate image analysis program on a personal computer, there is now the ability to produce and analyze high quality photographs with a modest level of resources. This report is the summary of a variety of efforts, all aimed at investigating the application of commonly available, mass-market photographic and computer equipment to photographic inspection and analysis of equipment and items. It contains results of equipment test and evaluation as well as a few selected example applications.

RecFOR proteins are important for DNA repair by homologous recombination in bacteria. The RecO protein from Thermus thermophilus was cloned, purified and characterized for its binding to oligonucleotides. The protein was crystallized alone and in complex with a 14-mer oligonucleotide. Both crystal forms grow under different crystallization conditions in the same space group, P3121 or P3221, with almost identical unit cell parameters. Complete data sets were collected to 2.8 Angstrom and 2.5 Angstrom for RecO alone and the RecO-oligonucleotide complex, respectively. Visual comparison of the diffraction patterns between the two crystal forms and calculation of an Rmerge of 33.9 percent on F indicate that one of the crystal forms is indeed a complex of RecO with bound oligonucleotide.

Cyprus has been divided since 1974. Greek Cypriots, nearly 80% of the population, live in the southern two thirds of the island. Turkish Cypriots live in the “Turkish Republic of Northern Cyprus” (recognized only by Turkey), with about 30,000 Turkish troops providing security. U.N. peacekeeping forces maintain a buffer zone between the two. Members of Congress have urged the Administration to be more active, although they have not proposed an alternative to the U.N.-sponsored talks.

Legislation has been proposed in the 107th Congress to combat the use and abuse of Ecstasy (MDMA) and other “club drugs.” In a 2001 survey, 12% of 12th graders reported ever having taken the drug. The Ecstasy Anti-Proliferation Act of 2000, enacted by the 106th Congress, directed the U.S. Sentencing Commission to increase penalties for Ecstasy offenses. As of March 2001, MDMA penalties became more severe than for powder cocaine but less severe than for heroin.

The purpose of this research project was to develop an improved understanding of how electrically driven processes, including electrocoalescence, acoustic agglomeration, and electric filtration, may be employed to efficiently treat problems caused by the formation of aerosols during DOE waste treatment operations. The production of aerosols during treatment and retrieval operations in radioactive waste tanks and during thermal treatment operations such as calcination presents a significant problem of cost, worker exposure, potential for release, and increased waste volume. There was anecdotal evidence in the literature that acoustic agglomeration and electrical coalescence could be used together to change the size distribution of aerosol particles in such a way as to promote easier filtration and less frequent maintenance of filtration systems. As such, those electrically driven technologies could potentially be used as remote technologies for improved treatment; however, existing theoretical models are not suitable for prediction and design. To investigate the physics of such systems, and also to prototype a system for such processes, a collaborative project was undertaken between Oak Ridge National Laboratory (ORNL) and the University of Texas at Austin (UT). ORNL was responsible for the larger-scale prototyping portion of the project, while UT was primarily responsible for the detailed …

This report provides a side-by-side comparison of the energy provisions of the new law with previously existing law, as well as the versions engrossed by the House and Senate in the 107th Congress. While the energy provisions in the House version were spread throughout the bill, the Senate version consolidated most of its energy provisions into Title IX - Energy. Both bills provided for the use of reserve land for renewable energy production. The House version also allowed for loans to farmers in response to high energy prices, while the Senate version did not.

This report discusses how vacancies in Congress are filled when a Senator or Representative dies, resigns, declines to serve, or is expelled or excluded from either house. The Constitution requires that vacancies in both houses be filled by special election, but in the case of the Senate, it empowers state legislatures to provide for temporary appointments by the state governor until special elections can be scheduled.

Vacancies in Congress occur due to the death, resignation, or declination (refusal to serve) of a Senator or Representative, or as the result of expulsion or exclusion by either house. The Constitution requires that vacancies in both houses be filled by special election, but in the case of the Senate, it empowers state legislatures to provide for temporary appointments by the state governor until special elections can be scheduled. This report describes this process.

This report evaluates how the existing U.S. Nuclear Regulatory Commission (NRC) regulatory structure and pending modifications would affect full deployment into radiologically uncontrolled areas of certain new depleted uranium (DU) uses being studied as part of the U.S. Department of Energy's DU uses research and development program. Such new DU uses include as catalysts (for destroying volatile organic compounds in off-gases from industrial processes and for hydrodesulfurization [HDS] of petroleum fuels), semiconductors (for fabricating integrated circuits, solar cells, or thermoelectric devices, especially if such articles are expected to have service in hostile environments), and electrodes (for service in solid oxide fuel cells, in photoelectrochemical cells used to produce hydrogen, and in batteries). The report describes each new DU use and provides a detailed analysis of whether any existing NRC licensing exemption or general license would be available to users of products and devices manufactured to deploy the new use. Although one existing licensing exemption was found to be possibly available for catalysts used for HDS of petroleum fuels and one general license was found to be possibly available for catalysts, semiconductors, and electrodes used in hydrogen production or batteries, existing regulations would require most users of products and devices deploying …
