Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the Office of the National Drug Control Policy's (ONDCP) contract with Ogilvy & Mather, the lead media campaign contractor for the National Youth Anti-Drug Media Campaign. GAO reviewed ONDCP investigations into: (1) the facts and circumstances surrounding actions taken by ONDCP after receiving the allegations that Ogilvy may have over-billed the government, and (2) allegations that Ogilvy had provided services unrelated to the contract and had submitted invoices under the contract for those services. The Director of ONDCP, General Barry McCaffrey, knew about the fraud allegations concerning Ogilvy's billing practices. GAO found that Director McCaffrey had a private meeting with Ogilvy's project director after internal ONDCP discussions of the need for an external audit. However, GAO found no evidence that this meeting affected any decision with respect to an external audit of Ogilvy's contract. GAO also found that Ogilvy did not write congressional testimony for ONDCP employees, which would have gone beyond the scope of its contract with ONDCP. Ogilvy did provide ONDCP with figures, research, and documentation for use in responding to congressional inquiries and testimony. Ogilvy did not provide any services to Director …

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the decisions by the United States to support new or expanded United Nations (U.N.) operations in the following four locations: Kosovo, East Timor, Sierra Leone, and the Democratic Republic of the Congo. These decisions were made between January 1999 and June 2000. This testimony focuses on: (1) whether GAO had sufficient access to agency records to conduct the study requested by Congress, (2) how Presidential Decision Directive 25 was used in deciding to support new or expanded U.N. operations, and (3) how the executive branch consulted with Congress during the Directive 25 decision process. GAO found that it lacked the full and independent access to agency records needed to complete its work. The intent of Directive 25 is to ensure selective and effective use of peacekeeping as a tool for advancing U.S. interests and to also establish factors to help assess whether U.S. support for an operation is appropriate. GAO found that Directive 25 factors were considered in the initial operation in East Timor, but GAO could not determine whether those factors were considered in other operations. Communications between Congress and the executive branch consisted …

Correspondence issued by the General Accounting Office with an abstract that begins "This report focuses on the federal involvement in acquiring human fetal tissue for preclinical research. Department of Health and Human Services (HHS) officials reported that the National Institute for Health (NIH) is the only federal agency under the Senate Labor, HHS, and Education Subcommittee's jurisdiction that sponsors research using human fetal tissue. According a GAO survey, 12,116 human fetal tissue samples were acquired during fiscal years 1997 through 1999 for use in NIH-sponsored research. In fiscal year 1999, three fetal tissue suppliers received federal funding. For therapeutic transplantation research, the NIH Revitalization Act requires written statements by the donor, the physician who obtained the tissue, and the researcher receiving the tissue to ensure that the provisions of the law are met. It also requires that all applicable and local laws must be followed. The costs to acquire human fetal tissue were low. Principal investigators reported that quality of tissue and compliance with federal regulations were their primary criteria for choosing a human fetal tissue supplier."

High level waste facilities at the Savannah River Site include several major structures that must meet seismic requirements, including the Defense Waste Processing Facility. Numerous geotechnical and geological investigations have been performed to characterize the in-situ static and dynamic properties of the soil sediments. These investigations have led to conclusions concerning the stability of foundation soils in terms of liquefaction potential and structure settlement. This report reviews past work that addresses seismic soil stability and presents the results of more recent analyses incorporating updated seismic criteria.

CO{sub 2} and O{sub 2} are mutually competitive at the active site of ribulose-1,5-biphosphate (RuBP) carboxylase/oxygenase (Rubisco). Rubisco contains two subunits, each present in eight copies. The 15-kD small subunit is coded by a family of nuclear RbcS genes. Until now, the role of the small subunit in Rubisco structure or catalytic efficiency is not known. Because of other work in eliminating the two RbcS genes in the green algo Chlamydomonas reinhardtii, it is now possible to address questions about the structure-function relationships of the eukaryotic small subunit. There are three specific aims in this project: (1) Alanine scanning mutagenesis is being used to dissect the importance of the {beta}A/{beta}B loop, a feature unique to the eukaryotic small subunit. (2) Random mutagenesis is being used to identify additional residues or regions of the small subunit that are important for holoenzyme assembly and function. (3) Attempts are being made to express foreign small subunits in Chlamydomonas to examine the contribution of small subunits to holoenzyme assembly, catalytic efficiency, and CO{sub 2}/O{sub 2} specificity.

The Savannah River Site (SRS) is evaluating technologies for removing radioactive cesium ({sup 137}Cs) from the supernate solutions stored in the high-level waste tanks at the site. Crystalline silicotitanate sorbent (IONSIV IE-911,{reg_sign} UOP LLC, Des Plaines, IL), which is very effective at removing cesium from high-salt solution, is one of three technologies currently being tested. Because of the extremely high inventory of {sup 137}Cs expected for the large columns of crystalline silicotitanate (CST) that would be used for treating the SRS supernate, any loss of flow or cooling to the columns could result in high temperatures from radiolytic heating. Also, even for normal operation, the CST would be exposed to the supernates for up to a year before being removed. Small-scale tests using simulant solutions were used to determine the long-term stability of the CST to the solutions at various temperatures. In the tests performed in this study, the cesium capacity of the CST decreased significantly (76%) as the temperature of the simulant and CST during loading was increased from 23 to 80 C. CST exposed to recirculating SRS average simulant solution at room temperature in a column test showed a slow decrease in cesium loading capacity (measured at 23 …

The final goal behind any numerical method is give the smallest wall-clock time for a given final time error or, conversely, the smallest run-time error for a given wall clock time, etc. Here a comparison will be given between adaptive mesh refinement schemes and non-adaptive schemes of higher order. It will be shown that in three dimension calculations that in order for AMR schemes to be competitive that the finest scale must be restricted to an extremely, and unrealistic, small percentage of the computational domain.

We describe the status of a sensitive search for halo axions with masses in the {mu}eV range. A tunable large-volume and low-loss microwave cavity is operated at low temperature in a strong magnetic field. Resonant Primakoff conversion of axions into photons takes place when the cavity frequency is matched to the axion mass. No positive signal has been found so far, and we are able to exclude hadronic axions as the dominant halo component over a significant axion mass range. Future plans for a detector upgrade are outlined.

The many motivations for employing agent-based computation in the social sciences are reviewed. It is argued that there exist three distinct uses of agent modeling techniques. One such use--the simplest--is conceptually quite close to traditional simulation in operations research. This use arises when equations can be formulated that completely describe a social process, and these equations are explicitly soluble, either analytically or numerically. In the former case, the agent model is merely a tool for presenting results, while in the latter it is a novel kind of Monte Carlo analysis. A second, more commonplace usage of computational agent models arises when mathematical models can be written down but not completely solved. In this case the agent-based model can shed significant light on the solution structure, illustrate dynamical properties of the model, serve to test the dependence of results on parameters and assumptions, and be a source of counter-examples. Finally, there are important classes of problems for which writing down equations is not a useful activity. In such circumstances, resort to agent-based computational models may be the only way available to explore such processes systematically, and constitute a third distinct usage of such models.

Solar opacities are presented from the center of the Sun to the photosphere. The temperatures, densities and hydrogen mass fractions are taken from the standard solar model. For the heavy element abundances the Grevesse mixture is used. In the solar interior photoabsorption is dominated by free-free absorption and they compare two sets of opacities based on two different models for the inverse bremsstrahlung. The radiative luminosities calculated from the two sets of opacities are compared with those predicted by previous models of the standard solar model and also with the known luminosity of the Sun. pressures, specific heats and the speed of sound in the solar plasma are also presented.

To provide a better understanding of the roles of a solid catalyst and the solvent in Direct Coal Liquefaction, a small reactor was equipped with a porous-walled basket which was permeable to the solvent but was not permeable to the coal or solid catalyst. With this equipment and a high volatile bituminous coal it was found that direct contact between the catalyst in the basket and the coal outside the basket is not required for catalyzed coal liquefaction. The character of the solvent in this system makes a significant difference in the conversion of the coal, the better solvents being strong donor solvents. Because of the extensive use of thermogravimetric analysis in this laboratory, it was noted that the peak temperature for volatiles evolution from coal was a reliable measure of coal rank. Because of this observation, a variety of coals of a range of ranks was investigated. It was shown in this work that measuring the peak temperature for volatiles evolution was a quite precise indicator of rank and correlated closely with the rank value obtained by measuring vitrinite reflectance, a more difficult measurement to make. This prompted the desire to know the composition of the volatile material evolved …

Stress corrosion crack (SCC) growth rate tests and analytical electron microscopy (AEM) studies were performed over a broad range of environments and heat treatments of Alloy 600. This effort was conducted to correlate bulk environmental conditions such as pH and electrochemical potential (EcP) with the morphology of the SCC crack. Development of a library of AEM morphologies formed by SCC in different environments is an important step in identifying the conditions that lead to SCC in components. Additionally, AEM examination of stress corrosion cracks formed in different environments and microstructures lends insight into the mechanism(s) of stress corrosion cracking. Testing was conducted on compact tension specimens in three environments: a mildly acidic oxidizing environment containing sulfate ions, a caustic environment containing 10% NaOH, and hydrogenated near-neutral buffered water. Additionally, stress corrosion cracking testing of a smooth specimen was conducted in hydrogenated steam. The following heat treatments of Alloy 600 were examined: mill annealed at 980 C (near-neutral water), mill annealed at 1010 C (steam), sensitized (acid and caustic), and mill annealed + healed to homogenize the grain boundary Cr concentration (caustic). Crack growth rate (CGR) testing showed that sensitized Alloy 600 tested in the mildly acidic, oxidizing environment containing sulfate …
