Russia's then-Premier Vladimir Putin ordered military, police, and security forces to enter the breakaway Chechnya region in September 1999, and these forces occupied most of the region by early 2000. The conflict has resulted in thousands of military and civilian casualties and the massive destruction of housing and infrastructure. Putin's rise to power and continuing popularity have been tied at least partly to his perceived ability to prosecute this conflict successfully. This report details the background on the conflict in the region, elections and peace-making, and related material over the Russian-Chechnyan conflict.

This report provides analysis of a number of factual, civil rights, and constitutional questions that have been raised regarding charitable choice in general. The analysis is generally focused on those provisions enacted as part of the 1996 welfare reform law. More recent charitable choice rules may give rise to the same or similar concerns. Primarily, this report focuses on civil rights concerns that have arisen in the context of charitable choice and First Amendment issues, as well as recent legal developments related to charitable choice.

Pressure-volume relationships were measured at room temperature for eight granular materials and one specimen of epoxy foam. The granular materials included hollow ceramic microspheres, spherical molybdenum powder, Ottawa sand, aluminum, copper, titanium and silicon carbide powders and glassy carbon spheres. Measurements were made to 0.9 GPa in a liquid medium press for all of the granular materials and to 3 GPa in a solid medium press for the ceramic microspheres and molybdenum powder. A single specimen of epoxy foam was compressed to 30 MPa in the liquid medium press. Bulk moduli were calculated as a function of pressure for the ceramic microspheres, the molybdenum powder and three other granular materials. The energy expended in compacting the granular materials was determined by numerically integrating pressure-volume curves. More energy was expended per unit volume in compacting the molybdenum powder to 1 GPa than for the other materials, but compaction of the ceramic microspheres required more energy per gram due to their very low initial density. The merge pressure, the pressure at which all porosity is removed, was estimated for each material by plotting porosity against pressure on a semi-log plot. The pressure-volume curves were then extrapolated to the predicted merge pressures and …

Correspondence issued by the Government Accountability Office with an abstract that begins "Defense trade impacts many issues of importance to the Department of Defense (DOD), including maintaining a healthy supplier base, protecting critical technologies, ensuring access to a secure supply of defense-related items and services, managing technology transfers, and increasing interoperability with allies. A critical element to guide decision makers is access to comprehensive and reliable data. The Committee on Armed Services, through its report on the National Defense Authorization Act for Fiscal Year 2006, directed GAO to identify and assess defense trade data. In response, we (1) identified defense trade data available from U.S. government sources and their limitations, and (2) determined defense trade balances as indicated by the data for years 2000 through 2004."

This report focuses on proposals offered to amend the federal income tax code to subsidize the expenses of families with children enrolled in the K-12 school of their choice. It begins with a discussion of K-12 education reform efforts to provide a context for the proposed tax subsidies. Next, it reviews existing federal tax provisions that could help families pay for the cost of their children’s K-12schooling. The report then analyzes the kind of proposals that have been introduced to expand existing federal tax benefits or to authorize new ones for families incurring K-12 education expenses.

With the Nation's coal-burning utilities facing the possibility of tighter controls on mercury pollutants, the U.S. Department of Energy is funding projects that could offer power plant operators better ways to reduce these emissions at much lower costs. Sorbent injection technology represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. It involves injecting a solid material such as powdered activated carbon into the flue gas. The gas-phase mercury in the flue gas contacts the sorbent and attaches to its surface. The sorbent with the mercury attached is then collected by the existing particle control device along with the other solid material, primarily fly ash. During 2001, ADA Environmental Solutions (ADA-ES) conducted a full-scale demonstration of sorbent-based mercury control technology at the Alabama Power E.C. Gaston Station (Wilsonville, Alabama). This unit burns a low-sulfur bituminous coal and uses a hot-side electrostatic precipitator (ESP) in combination with a Compact Hybrid Particulate Collector (COHPAC{reg_sign}) baghouse to collect fly ash. The majority of the fly ash is collected in the ESP with the residual being collected in the COHPAC{reg_sign} baghouse. Activated carbon was injected between the ESP and COHPAC{reg_sign} units to collect the mercury. Short-term mercury removal …

This report documents the activities associated with the installation in 2004 of three groundwater monitoring wells at Morrill, Kansas, and the subsequent sampling of these wells and the six existing Kansas Department of Health and Environment (KDHE) monitoring wells. Also sampled were known private wells located within and downgradient of an area of groundwater contaminated with carbon tetrachloride. These activities were conducted as part of an ongoing environmental investigation at Morrill that is being performed by the Environmental Research Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), has entered into an interagency agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. The need for three additional monitoring wells at Morrill to supplement the existing sixwell network initially installed by the KDHE (GeoCore 1996) was documented in a letter report (Argonne 2003a), based on the data collected in October 2003, during the Phase I-Phase II expedited site characterization (Argonne 2004a). In December 2003, following approval …

This paper investigates ballasting and remineralization controls of carbon sedimentation in the twilight zone (100-1000 m) of the Southern Ocean. Size-fractionated (<1 {micro}m, 1-51 {micro}m, >51 {micro}m) suspended particulate matter was collected by large volume in-situ filtration from the upper 1000 m in the Subantarctic (55 S, 172 W) and Antarctic (66 S, 172 W) zones of the Southern Ocean during the Southern Ocean Iron Experiment (SOFeX) in January-February 2002. Particles were analyzed for major chemical constituents (POC, P, biogenic Si, CaCO3), and digital and SEM image analyses of particles were used to aid in the interpretation of the chemical profiles. Twilight zone waters at 66 S in the Antarctic had a steeper decrease in POC with depth than at 55 S in the Subantarctic, with lower POC concentrations in all size fractions at 66 S than at 55 S, despite up to an order of magnitude higher POC in surface waters at 66 S. The decay length scale of >51 {micro}m POC was significantly shorter in the upper twilight zone at 66 S ({delta}{sub e}=26 m) compared to 55 S ({delta}{sub e}=81 m). Particles in the carbonate-producing 55 S did not have higher excess densities than particles from the …

A letter report issued by the Government Accountability Office with an abstract that begins "Terrorist attacks on U.S. chemical facilities could damage public health and the economy. While the Environmental Protection Agency (EPA) formerly led federal efforts to ensure chemical facility security, the Department of Homeland Security (DHS) is now the lead federal agency coordinating efforts to protect these facilities from terrorist attacks. GAO reviewed (1) DHS's actions to develop a strategy to protect the chemical industry, (2) DHS's actions to assist in the industry's security efforts and coordinate with EPA, (3) industry security initiatives and challenges, and (4) DHS's authorities and whether additional legislation is needed to ensure chemical plant security. GAO interviewed DHS, EPA, and industry officials, among others."

Suppose that we are given two probability densities p{sub 0}(E{prime}) and p{sub 1}(E{prime}) for the energy E{prime} of an outgoing particle, p{sub 0}(E{prime}) corresponding to energy E{sub 0} of the incident particle and p{sub 1}(E{prime}) corresponding to incident energy E{sub 1}. If E{sub 0} < E{sub 1}, the problem is how to define p{sub {alpha}}(E{prime}) for intermediate incident energies E{sub {alpha}} = (1 - {alpha})E{sub 0} + {alpha}E{sub 1} with 0 < {alpha} < 1. In this note the author considers three ways to do it. They begin with unit-base interpolation, which is standard in ENDL and is sometimes used in ENDF. They then describe the equiprobable bins used by some Monte Carlo codes. They then close with a discussion of interpolation by corresponding-points, which is commonly used in ENDF.

We present here the results of a measurement of the three semileptonic form factors involved in the decay B{sup 0} {yields} D*{ell}{nu}, where {ell} is one of the two light charged leptons (i.e. an electron or muon--though the final results in this work are determined only for {ell} = electron). This measurement uses the Babar 2000-2002 data set, which is altogether approximately 85 x 10{sup 6} B{bar B}-pairs in 78 fb{sup -1} of integrated luminosity. The D*{sup +} was reconstructed in the channel D*{sup +} {yields} D{sup 0}{pi}{sup +}, and the D{sup 0} in the channel D{sup 0} {yields} K{sup -}{pi}{sup +}. This analysis was based ultimately on {approx} 16,386 reconstructed events with an estimated background contamination of {approx} 15%. The method of the measurement was to perform a unbinned maximum likelihood fit in the four kinematic variables that describe the decay for the three form factor parameters R{sub 1}, R{sub 2}, and {rho}{sup 2}. The results obtained for the form factor ratios are R{sub 1} = 1.328 {+-} 0.055 {+-} 0.025 {+-} 0.025 and R{sub 2} = 0.920 {+-} 0.044 {+-} 0.020 {+-} 0.013 for the ratios and {rho}{sup 2} = 0.769 {+-} 0.039 {+-} 0.019 {+-} 0.032 for …
