A method is presented for the determination of uranium (as U/sup 238/) in uraniuni-loaded graphite fuel elenients by a non-destructive, direct radioactivity analysis technique. A 200-cbannel pulse-height analyzer, equipped with a 3 in. x 3 in. NaI(Tl) crystal, is used to measure the Np/sup 239/ radioactivity of the neutron-irradiated samples. The amount of U/sup 238/ in the test samples is deterimined quantitatively by comparing the Np/sup 239/ radioactivity induced in each sample with the Np/sup 239/ radioactivity induced into known standards of U/sup 238/ processed under the same conditions as the test samples. The limit of detection for U/sup 238/in samples of normal uranium composition for this method is about 1.0 x l0-4 ug. (auth)

A letter report issued by the Government Accountability Office with an abstract that begins "Higher education has increasingly become critical to our nation's cultural, social, and economic well-being, with 90 percent of the fastest-growing jobs in the knowledge economy requiring some postsecondary education. While a college graduate can expect to earn, on average, approximately $1 million more over the course of his or her working life than those with a high school diploma, most students and their families can expect to pay more on average for college than they did just a year ago. Moreover, many are concerned that the increases in the cost of college may be discouraging large numbers of individuals, particularly minority and low-income individuals, from pursuing higher education. The topic of college affordability continues to be an issue of great concern. Various policymakers, national associations, and philanthropic foundations have documented the growth in college tuition and its potentially adverse effects on access to higher education and rates of degree completion. Recent years have witnessed the introduction of many federal-, state-, and institution-level initiatives aimed at curbing tuition increases, yet tuition continues to rise. Congress asked GAO to provide information on trends in higher education enrollments, tuition …

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) spends millions of dollars each year to acquire information technology (IT) services through the General Services Administration's (GSA) Federal Supply Schedule (FSS). However, DOD has not been taking steps critical to ensuring that it gets the best services at the best prices. GAO's review of 22 DOD orders revealed that 17 of them were placed without seeking competitive quotes. GSA's established procedures require that agencies seek competitive quotes to ensure that the government gets the best price for IT services. Many DOD contracting officers were unaware of this requirement and placed orders under FSS contracts without seeking quotes from multiple contractors. The Federal Acquisition Regulation covering FSS contracts does not provide clear guidance to contracting officers on these special ordering procedures."

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Federal Air Marshal Service (FAMS) has undergone a number of changes in recent years, including a 2003 transfer from the Transportation Security Administration (TSA) to the U.S. Immigration and Customs Enforcement Bureau (ICE), and a 2005 transfer from ICE back to TSA. A key aspect of federal air marshals' operating procedures is the discreet movement through airports as they check in for their flight, transit screening checkpoints, and board the aircraft. This report discusses FAMS's (1) transfer to ICE and key practices that could facilitate its return to TSA, and (2) management of mission-related incidents that affect air marshals' ability to operate discreetly."

A chapter report issued by the General Accounting Office with an abstract that begins "Since the end of the Cold War, the United States and its European allies are using smaller militaries, disbursing more development assistance, and increasing their reliance on multilateral organizations to provide for European security. Despite reductions in force levels and budgets, U.S. and European military forces have been actively engaged in peacekeeping and other security-enhancing activities in the region. The United States and its European allies have contributed to stability in the Balkans through various military and financial means. The Balkans operations have highlighted numerous shortfalls in the military capabilities of European allies, but competing budgetary priorities may limit their ability to remedy them before the end of the decade. Defense expenditures are expected to remain relatively flat in constant 2000 dollars over the next four to five years for most European allies, placing major defense initiatives sponsored by NATO and the European Union in jeopardy."

A Demonstration Reaction Clarifier - Gravity Filtration System with a 1600 GPM throughput capability was in operation at the joint DOE-SDG and E-MAGMA test facility located in the Salton Sea Geothermal Field, southern California, during the summer of 1979. The system, which was designed to condition spent effluent from a 10 MWe-size geothermal power plant, removes supersaturated dissolved species and residual suspended solids from brine prior to subsurface brine disposal via injection wells. The post-processing chemical stability of conditioned effluents was established by means of anaerobic incubation tests at 90/sup 0/C. The effect of residual dissolved polymer, that might be used for the purpose of scale control in upstream power plant components on the efficiency of reaction clarification, was also evaluated. Membrane filtration and core tests were used to assess the injectability of processed brine. It was found that the clarifier-filter operational procedures and system design permitted oxygenation of the brine by air intrusion. This resulted in partial stabilization of dissolved silica and precipitation of oxides of iron. As a consequence, conditioned brine injectability was poor. However, elimination of the air intrusion problem would result in a substantial improvement in brine quality. Residual amounts of dissolved polyaminoethylene (20 ppm, by …

A letter report issued by the Government Accountability Office with an abstract that begins "Much attention has focused on the "offshoring" of services to lower-wage locations abroad. Offshoring generally refers to an organization's purchase of goods or services from abroad that were previously produced domestically. Extensive public debate has arisen about both the potential benefits of services offshoring, such as lower consumer prices and higher U.S. productivity, as well as the potential costs, such as increased job displacement for selected U.S. workers. In response to widespread congressional interest, GAO conducted work under the Comptroller General's authority to help policy makers better understand the potential impacts and policy implications of services offshoring. This report: (1) provides an overview of experts' views on the potential impacts of services offshoring, (2) describes the types of policies that have been proposed in response to offshoring, and (3) highlights some key areas where additional research might help advance the debate about offshoring. In its comments, the Department of Commerce generally agreed with the findings of this report. Commerce, Treasury, and the Office of the United States Trade Representative also provided technical comments that have been incorporated as appropriate."

Growing concern over climate change is prompting new thinking about the technologies used to generate electricity. In the future, it is possible that new government policies on greenhouse gas emissions may favor electric generation technology options that release zero or low levels of carbon emissions. The Western U.S. has abundant wind and coal resources. In a world with carbon constraints, the future of coal for new electrical generation is likely to depend on the development and successful application of new clean coal technologies with near zero carbon emissions. This scoping study explores the economic and technical feasibility of combining wind farms with advanced coal generation facilities and operating them as a single generation complex in the Western US. The key questions examined are whether an advanced coal-wind hybrid (ACWH) facility provides sufficient advantages through improvements to the utilization of transmission lines and the capability to firm up variable wind generation for delivery to load centers to compete effectively with other supply-side alternatives in terms of project economics and emissions footprint. The study was conducted by an Analysis Team that consists of staff from the Lawrence Berkeley National Laboratory (LBNL), National Energy Technology Laboratory (NETL), National Renewable Energy Laboratory (NREL), and …

The basic idea is to implement Thomson scattering with free electron laser (FEL) radiation at near-solid density plasmas as a diagnostic method which allows the determination of plasma temperatures and densities in the warm dense matter (WDM) regime (free electron density of n{sub e} = 10{sup 21}-10{sup 26} cm{sup -3} with temperatures of several eV). The WDM regime [1] at near-solid density (n{sub e} = 10{sup 21}-10{sup 22} cm{sup -3}) is of special interest because, it is where the transition from an ideal plasma to a degenerate, strongly coupled plasma occurs. A systematic understanding of this largely unknown WDM domain is crucial for the modeling and understanding of contemporary plasma experiments, like laser shock-wave or Z-pinch experiments as well as for inertial confinement fusion (ICF) experiments as the plasma evolution follows its path through this domain.

A novel fiber optic downhole fluid analyzer has been developed for operation in production wells. This device will allow real-time determination of the oil, gas and water fractions of fluids from different zones in a multizone or multilateral completion environment. The device uses near infrared spectroscopy and induced fluorescence measurement to unambiguously determine the oil, water and gas concentrations at all but the highest water cuts. The only downhole components of the system are the fiber optic cable and windows. All of the active components--light sources, sensors, detection electronics and software--will be located at the surface, and will be able to operate multiple downhole probes. Laboratory testing has demonstrated that the sensor can accurately determine oil, water and gas fractions with a less than 5 percent standard error. Once installed in an intelligent completion, this sensor will give the operating company timely information about the fluids arising from various zones or multilaterals in a complex completion pattern, allowing informed decisions to be made on controlling production. The research and development tasks are discussed along with a market analysis.

Surface spectral reflectance (albedo) is a fundamental variable affecting the transfer of solar radiation and the Earth’s climate. It determines the proportion of solar energy absorbed by the surface and reflected back to the atmosphere. The International Panel on Climate Change (IPCC) identified surface albedo among key factors influencing climate radiative forcing. Accurate knowledge of surface reflective properties is important for advancing weather forecasting and climate change impact studies. It is also important for determining radiative impact and acceptable levels of greenhouse gases in the atmosphere, which makes this work strongly linked to major scientific objectives of the Climate Change Research Division (CCRD) and Atmospheric Radiation Measurement (ARM) Program. Most significant accomplishments of eth project are listed below. I) Surface albedo/BRDF datasets from 1995 to the end of 2004 have been produced. They were made available to the ARM community and other interested users through the CCRS public ftp site ftp://ftp.ccrs.nrcan.gc.ca/ad/CCRS_ARM/ and ARM IOP data archive under “PI data Trishchenko”. II) Surface albedo properties over the ARM SGP area have been described for 10-year period. Comparison with ECMWF data product showed some deficiencies in the ECMWF surface scheme, such as missing some seasonal variability and no dependence on sky-conditions which …

Crude oil occurs in many different forms throughout the world. An important characteristic of crude oil that affects the ease with which it can be produced is its density and viscosity. Lighter crude oil typically can be produced more easily and at lower cost than heavier crude oil. Historically, much of the nation's oil supply came from domestic or international light or medium crude oil sources. California's extensive heavy oil production for more than a century is a notable exception. Oil and gas companies are actively looking toward heavier crude oil sources to help meet demands and to take advantage of large heavy oil reserves located in North and South America. Heavy oil includes very viscous oil resources like those found in some fields in California and Venezuela, oil shale, and tar sands (called oil sands in Canada). These are described in more detail in the next chapter. Water is integrally associated with conventional oil production. Produced water is the largest byproduct associated with oil production. The cost of managing large volumes of produced water is an important component of the overall cost of producing oil. Most mature oil fields rely on injected water to maintain formation pressure during production. …

New technologies are needed that neutralize contaminant toxicity and control physical transport mechanisms that mobilize sediment contaminants. The last 12 months of this comprehensive project investigated the use of combinations of sequestering agents to develop in situ active sediment caps that stabilize mixtures of contaminants and act as a barrier to mechanical disturbance under a broad range of environmental conditions. Efforts focused on the selection of effective sequestering agents for use in active caps, the composition of active caps, and the effects of active cap components on contaminant bioavailability and retention. Results from this project showed that phosphate amendments, some organoclays, and the biopolymer, chitosan, were very effective at removing metals from both fresh and salt water. These amendments also exhibited high retention (80% or more) of most metals indicating reduced potential for remobilization to the water column. Experiments on metal speciation and retention in contaminated sediment showed that apatite and organoclay can immobilize a broad range of metals under both reduced and oxidized conditions. These studies were followed by sequential extractions to evaluate the bioavailability and retention of metals in treated sediments. Metal fractions recovered in early extraction steps are more likely to be bioavailable and were termed the …

In this letter we continue the calculation of master integrals for massless three-loop form factors by giving analytical results for those diagrams which are relevant for the fermionic contributions proportional to N{sub F}{sup 2}, N{sub F} {center_dot} N, and N{sub F}/N. Working in dimensional regularization, we express one of the diagrams in a closed form which is exact to all orders in {epsilon}, containing {Lambda}-functions and hypergeometric functions of unit argument. In all other cases we derive multiple Mellin-Barnes representations from which the coefficients of the Laurent expansion in {epsilon} are extracted in an analytical form. To obtain the finite part of the three-loop quark and gluon form factors, all coefficients through transcendentality six in the Riemann {zeta}-function have to be included.
