Technical Assessment of Zhao and Thurman's 2001 Evaluation of the Effects of COPS Grants on Crime (open access)

Technical Assessment of Zhao and Thurman's 2001 Evaluation of the Effects of COPS Grants on Crime

Correspondence issued by the General Accounting Office with an abstract that begins "Community Oriented Policing Services (COPS) is a federal public safety program whose goals are to add officer positions to the streets of communities nationwide and to promote community policing. Since the program's inception in 1994, local law enforcement agencies have received billions of dollars in grants to hire additional officers, acquire technology and civilian personnel, and implement innovative crime-prevention programs. To receive COPS grants, agencies are expected to implement or enhance community policing strategies illustrating community partnerships, problem solving, and organizational commitment. Given the large expenditures of funds, it is important for policy makers, among others, to have sound information on the effectiveness of the COPS program in reducing crime. Congress asked us to review one evaluation of the effectiveness of the COPS program--by Zhao and Thurman--and to render an assessment of its quality. In this report, we provide information on the extent to which this particular study's conclusions are supported by the data the researchers used and the analyses they conducted. GAO statisticians and methodology specialists reviewed the study using standard and widely accepted statistical and social science research principles."

Sets of Reports and Articles Regarding Cement Wastes Forms Containing Alpha Emitters that are Potentially Useful for Development of Russian Federation Waste Treatment Processes for Solidification of Weapons Plutonium MOX Fuel Fabrication Wastes for

This is a set of nine reports and articles that were kindly provided by Dr. Christine A. Langton from the Savannah River Site (SRS) to L. J. Jardine LLNL in June 2003. The reports discuss cement waste forms and primarily focus on gas generation in cement waste forms from alpha particle decays. However other items such as various cement compositions, cement product performance test results and some cement process parameters are also included. This set of documents was put into this Lawrence Livermore National Laboratory (LLNL) releasable report for the sole purpose to provide a set of documents to Russian technical experts now beginning to study cement waste treatment processes for wastes from an excess weapons plutonium MOX fuel fabrication facility. The intent is to provide these reports for use at a US RF Experts Technical Meeting on: the Management of Wastes from MOX Fuel Fabrication Facilities, in Moscow July 9-11, 2003. The Russian experts should find these reports to be very useful for their technical and economic feasibility studies and the supporting R&D activities required to develop acceptable waste treatment processes for use in Russia as part of the ongoing Joint US RF Plutonium Disposition Activities.

Cesium Eluate Evaporation Solubility and Physical Property Behavior (open access)

Cesium Eluate Evaporation Solubility and Physical Property Behavior

The baseline flowsheet for low activity waste (LAW) in the Hanford River Protection Project (RPP) Waste Treatment Plant (WTP) includes pretreatment of supernatant by removing cesium using ion exchange. When the ion exchange column is loaded, the cesium will be eluted with a 0.5M nitric acid (HNO3) solution to allow the column to be conditioned for re-use. The cesium eluate solution will then be concentrated in a vacuum evaporator to minimize storage volume and recycle HNO3. To prevent the formation of solids during storage of the evaporator bottoms, criteria have been set for limiting the concentration of the evaporator product to 80 percent of saturation at 25 degrees C. Prior work has collected fundamental data for predicting solubility and other physical property measurements. Other ongoing efforts have involved the development of a computer model to predict solubility and physical properties during evaporation. Evaporation experiments were conducted with cesium eluate simulant generated from a pilot scale experiment in the Thermal Fluids Lab (TFL) at the Savannah River Technology Center (SRTC). The data from the experiments will be used to validate the modeling data.

Electroweak and top physics at CDF in Run II (open access)

Electroweak and top physics at CDF in Run II

The CDF experiment at the Tevatron has used p{bar p} collisions at {radical}s = 1.96 TeV to measure the production cross sections of W and Z bosons using several leptonic final states. An indirect measurement of the W width and the ratio of tau and electron electroweak couplings have been extracted. The forward-backward charge asymmetry, A{sub FB}, in Drell-Yan dilectron production has been measured up to an invariant mass of 600 GeV/c{sup 2}. CDF has also started looking for WW production in the dilepton channel, WW{prime} {yields} ll{prime}vv, with the aim of measuring its cross section and derive limits on the anomalous WWZ and WW{gamma} couplings. The presence of a top quark signal in the Tevatron data has been reestablished by measuring the top quark pair production cross section in the dilepton channel, t{bar t} {yields} WbW{bar b} {yields} {bar l}v{sub l}bl{prime}{bar v}{sub l{prime}}{bar b} and in the lepton plus jets channel, t{bar t} {yields} WbW{bar b} {yields} q{bar q}lbl{bar b}{sub l}{bar b} + {bar l}v{sub l}bq{bar q}{prime}{bar b}. A pre-tagged lepton plus jets sample has also been used to reconstruct the top quark mass.

Liquid film/polymer interfaces (open access)

Liquid film/polymer interfaces

The objectives were: (1) Through experimental studies, advance the fundamental understanding of the principles that govern adsorption and wetting phenomena at polymer and organic surfaces. (2) Establish a firm scientific basis for improving the design of coatings for metal fin cooling surfaces used to control the wetting of water condensate for optimum energy efficiency. Several important findings were: (1) water adsorbed at hydrophobic surfaces has a liquid-like structure, in contrast to the generally held view of an ordered structure; (2) Correlations of large amounts of contact angle wetting data of grafted alkyl chain compounds showed a distinct link between the contact angle and the conformational ordering of the chains; (3) water adsorption at long chain alkysiloxane films showed a strong pH dependence on the film stability, which can be attributed to interfacial chemical effects on the siloxane network.

To prevent the formation of solids during storage of the evaporator bottoms, criteria have been set for limiting the concentration of the evaporator product to 80 percent of saturation at 25 degrees C. A fundamental element of predicting evaporator product solubility is to collect data that can be used to estimate key operating parameters. The data must be able to predict evaporator behavior for a range of eluate concentrations that are evaporated to the point of precipitation. Parameters that were selected for modeling include solubility, density, viscosity, thermal conductivity, and heat capacity. Of central importance is identifying the effect of varying feed components on overall solubility. The point of solubility defines the upper limit for eluate evaporation operations and liquid storage. The solubility point …

Stretched and Filtered Transport Precondititioning of Sn Problems Part 2: Heterogeneous Media (open access)

Stretched and Filtered Transport Precondititioning of Sn Problems Part 2: Heterogeneous Media

In [1], we presented the stretched filtered transport synthetic acceleration method (SFTSA) for homogeneous media. Both SFTSA and SFTSA preconditioned Krylov were shown to be effective iterative schemes in homogeneous media due to the predictable structure of the iteration eigenvalues. In heterogeneous media or on non-uniform grids, the eigenvalue structure is unpredictable for general problems, making the filter strength a for optimal SFTSA extremely problem dependent. Leaving Q set to the optimal value (in each cell by table lookup) predicted by homogeneous media theory can make SFTSA divergent, even for relatively mild heterogeneities. Thus, SFTSA is more fragile than DSA in the sense that most DSA schemes break down only for much more severe heterogeneities. Fortunately, breakdown of SFTSA occurs with large negative eigenvalues, and Krylov methods preconditioned with SFTSA remain effective for such problems. Therefore, with a Krylov scheme ''wrapped around'' SFTSA, the resulting method is relatively insensitive to the filter strength, and a user may achieve reasonably good performance, if not optimal, with a fixed a over a wide range of heterogeneous problems.

Oral History Interview with Agadito Silva (open access)

Oral History Interview with Agadito Silva

The National Museum of the Pacific War presents an oral interview with Agaito Silva. Silva was inducted into the US Army in January 1941. Trained in anti-aircraft guns at Fort Bliss, Texas he was assigned to the 200th Coast Artillery. Several months later the unit was shipped to Fort Stotsenberg, Luzon, Philippines. He describes the Japanese attack on 8 December 1941 and the serious shortages of food and medical supplies that developed. He tells of retreating to Corregidor and of being wounded by shell fragments. After surrendering on 6 May 1942, Silva tells how the prisoners were treated. They sent to Bilibid Prison and then to Cabanatuan. He was then taken to Japan to work in the mines and gives several anecdotes describing the inhumane treatment of the prisoners by the Japanese. He relates how after the Japanese surrender, food and medical supplies were dropped to the POW camp. Silva returned to the United States on 18 October 1945.
