A letter report issued by the General Accounting Office with an abstract that begins "Damage, theft, vandalism, and pranks occurred in the White House complex during the 2001 presidential transition. Several Executive Office of the President (EOP) staff claim that they observed (1) messy offices containing excessive trash or personal items, (2) numerous prank signs containing derogatory and offensive statements about the president, (3) government property that was damaged, and (4) missing items. Further, EOP staff believed that what they observed during the transition was done intentionally. Some former Clinton administration staff acknowledged that they observed some damaged items and prank signs. However, the former Clinton administration staff said that (1) the amount of trash found during the transition was what could be expected; (2) they did not take the missing items; (3) some furniture was unintentionally broken before the transition, and little money was spent on repairs and upkeep during the administration; and (4) many of the reported observations were not of vandalism. This report makes several recommendations regarding the prevention and documentation of vandalism during future presidential transitions."

Correspondence issued by the General Accounting Office with an abstract that begins "Government, commercial, and foreign entities rely almost exclusively on information generated by the United States space surveillance network to reduce the risk of space collisions when launching and operating their respective space missions. The network is maintained and operated by the Air Force Space Command; surveillance data is processed and an unclassified portion is sent to the National Aeronautics and Space Administration (NASA) and made available to users. Currently, the Air Force Space Command is proposing a pilot study to replace the current NASA arrangement with one using a Federally Funded Research and Development Center (FFRDC). The study would test the FFRDC's ability to support commercial and foreign entities with space surveillance information and to ensure there is a sufficient market for the data. If the study is approved by the Air Force and Department of Defense, and if authorizing legislation is enacted that includes providing space surveillance support to foreign and commercial entities as part of DOD's mission, the study will begin in about 1 year."

Correspondence issued by the General Accounting Office with an abstract that begins "GAO reviewed the roles and responsibilities of the General Services Administration's (GSA) Federal Supply Service (FSS) and Federal Technology Service (FTS). Specifically, (1) the possible impact of the current FSS/FTS overlap on the prices paid for and quality of the services provided customer agencies by FSS and FTS, (2) whether the use of streamlined practices and procedures could result in savings and increases in service effectiveness, and (3) whether the statement of work that governs the study of the FSS and FTS that GSA has under contract will likely result in the kind of information needed to assess whether the current organization needs to be restructured."

Correspondence issued by the General Accounting Office with an abstract that begins "Title I of the Global AIDS and Tuberculosis Relief Act provided for the creation of a trust fund to be administered by the World Bank to combat the HIV/AIDS epidemic. The act mandates that the Comptroller General of the United States submit a report to Congress evaluating the effectiveness of the fund within 2 years of enactment of the statute. In January 2002, the Global Fund to Fight AIDS, Tuberculosis, and Malaria was formally established, but as of May 2002, funds had not been disbursed to any project. GAO reviewed the status of the Global Fund and found that as of May 2002, the Global Fund had received more than $2 billion in pledges, with $700 million available for disbursement in 2002. The United States has pledged a total of $300 million to the Fund through fiscal year 2002, and the administration has requested an additional $200 million in its fiscal year 2003 budget request. At its first board meeting in January 2002, the Fund called for proposals for its first round of grants and had received 322 proposals for projects in 101 countries by the March deadline. …

A letter report issued by the General Accounting Office with an abstract that begins "The issue of homeland security crosscuts numerous policy domains, impinging on the expertise and resources of every level of government, the private sector, and the international community. GAO found that although combating terrorism crossed organizational boundaries, it did not sufficiently coordinate the activities of the 40 federal entities involved, resulting in duplication and gaps in coverage. The homeland security efforts of public and private entities do not yet represent a unified approach, although key supporting elements for such an approach are emerging. Progress has been made in developing a framework to support a more unified effort. Other remaining key elements--a national strategy, establishment of public and private sector partnerships, and the definition of key terms--are either not in place yet or are evolving. At the same time, key terms, such as "homeland security," have not been defined officially; consequently, certain organizational, management, and budgetary decisions cannot currently be made across agencies. In the interim, the potential exists for an uncoordinated approach to homeland security that may lead to duplication of efforts or gaps in coverage, misallocation of resources, and inadequate monitoring of expenditures."

A letter report issued by the General Accounting Office with an abstract that begins "The U.S. Army Corps of Engineers' February 1992 Final Interim Feasibility Study and Environmental Impact Statement reported that deepening the Delaware River ship channel from 40 to 45 feet was economically justified and environmentally feasible. However, GAO found that it does not provide a reliable basis for deciding whether to proceed with the project. GAO identified several miscalculations, invalid assumptions, and the use of significantly outdated information on the Corps' benefits estimate. In addition, several unresolved issues and uncertainties were not factored into the Corps' economic analysis, the outcome of which could either increase or decrease the benefits and costs of the project. Because of these shortcomings, the actual economic merits of the project will be unclear until the Corps reanalyzes it. The Corps of Engineers has largely addressed the environmental concerns of federal and state environmental agencies. However, several unresolved issues remain, including the issuance of a permit from the state of Delaware governing construction projects that affect state waters."

Testimony issued by the General Accounting Office with an abstract that begins "Federal, state, and local governments, and the private sector, are taking steps to strengthen the safety and security of the American people, including actions to strengthen border and port security, airport security, health and food security and to protect critical infrastructure. There are date, information-sharing, and technology challenges facing the country in developing and implementing a national preparedness strategy. The nature of the terrorist threat makes it difficult to identify and differentiate information that can provide an early indication of a terrorist threat from the mass of data available to those in positions of authority. Further, the nation faces considerable cultural, legal, and technical barriers in effectively collecting and sharing information. Many technologies key to addressing threats are not yet available, and many existing technologies have not effectively been adapted for the threats the country now faces. The real challenge, however, is not just to find the right solutions to each of these problems but to weave solutions together in an integrated and intelligent fashion."

Accurate description of transport pathways on the gross scale, the location of contamination, and characterization of heterogeneity within the vadose zone, are now realized as vital for proper treatment, confinement and stabilization of subsurface contamination at Department of Energy (DOE) waste sites. Electromagnetic (EM) methods are ideal for these tasks since they are directly sensitive to the amount of fluid present in porous media, as well as fluid composition. At many DOE sites it is necessary to employ lower frequency (<1 MHz) or diffusive electromagnetic fields because of the inability of ground penetrating radar (GPR) to penetrate to sufficient depths. The high frequency impedance method, which operated in the diffusive frequency range (10 Hz to 1 MHz), as well as the low end of the spectrum employed by GPR (1MHz-10 MHz), is an ideal technique to delineate and map the aforementioned targets. The method has clearly shown the potential to provide needed information on variations in subsurface saturation due to local storage tanks and perched water zones, as well as mapping geological structures related to the subsurface hydrological properties and heterogeneity within the vadose zone. Although it exhibits certain advantages over other EM methods, the impedance method comes with a …

Despite over 50 years of experience in transporting radioactive tank wastes to and from equipment and tanks at the Department of Energy's Hanford, Savannah River, and Oak Ridge sites, waste slurry transfer pipelines and process piping become plugged on occasion. At Hanford, several tank farm pipelines are no longer in service because of plugs. At Savannah River, solid deposits in the outlet line of the 2H evaporator have resulted in an unplanned extended downtime. Although waste transfer criteria and guidelines intended to prevent pipeline plugging are in place, they are not always adequate. To avoid pipeline plugging in the future, other factors that are not currently embodied in the transfer criteria may need to be considered. The work summarized here is being conducted to develop a better understanding of the chemical and waste flow dynamics during waste transfer. The goal is to eliminate pipeline plugs by improving analysis and engineering tools in the field that incorporate this understanding.

Characterization data describing radioactive materials (RAM) in storage are likely those associated with the processes that produced the materials or with the mission for which they were produced. Along with impurity data, often absent or unknown as a result of post-processing storage environment is moisture content. Radiolysis of moisture may lead to a hydrogen flammability hazard within a closed volume such as a storage can or a transportation package. This paper offers a practical means of qualifying payloads of unknown moisture content for shipment within Type B packaging, while supporting the DOE program to maintain radworker dose as low as reasonable achievable (ALARA). Specifically, the paper discusses part of a qualification program carried out at the Savannah River Site for onsite shipment of legacy RAM within the DDF-1 package. The DDF-1 is an onsite-only prototype of the currently certified 9975 package. Measurement of storage-can lid bulge can provide an upper bound for pressure within a storage can. Subsequent belljar testing can measure the rate of gas leakage from a storage can. These actions are shown sufficient to ensure that the performance of the 9975 containment vessels can accommodate the deflagration energy from flammable gas mixtures within Normal Conditions of Transport, …

Band type closure rings are commonly used for securing the drum lid on radioactive material packages of lower weight classifications. Lid installation is achieved by placing the band around the perimeter of the lidded drum and tightening the single bolt in stages until a designated torque value is obtained. The band is subjected to heavy rapping with a soft hammer during installation to equilibrate the band strains around the drum perimeter. The study described here investigated the strain distributions in the band throughout the installation process. The results show that a uniform strain distribution is achieved during installation and that the hammering of the band aids in achieving the uniform distribution. The results of the strain levels after the drop test indicate that the locking rings maintain some pre-tension, even after severe targeted drops that crush a portion of the drum top.

After adoption, these rulemaking actions are codified into the Texas Administrative Code.

A letter report issued by the General Accounting Office with an abstract that begins "The Railroad Revitalization and Regulatory Reform Act of 1976 and the Staggers Rail Act of 1980 gave freight railroads increased freedom to price their services according to market conditions. A number of shippers are concerned that freight railroads have used these pricing freedoms to unreasonably exercise their market power in setting rates for shippers with fewer alternatives to rail transportation. This report updates the rate information in GAO's 1999 report (RCED-99-93) using selected commodities and with effective competitive transportation alternatives. From 1997 through 2000, rail rates generally decreased, both nationwide and for many of the specific commodities and markets that GAO examined. However, rail rates for some commodities and distance categories--such as wheat moving long distances and coal moving short distances--have stayed about the same or increased. In other instances, such as wheat moving medium distances, rail rates stayed about the same or decreased. Overall, the proportion of rail shipments above the Surface Transportation Board's statutory jurisdictional threshold for considering rate relief actions--where railroad revenues for the shipment exceed 180 percent of variable costs--stayed relatively constant at 30 percent from 1997 through 2000. However, the proportion …

Homogeneous charge compression ignition (HCCI) engines are being considered as an alternative to diesel engines. The HCCI concept involves premixing fuel and air prior to induction into the cylinder (as is done in current spark-ignition engine) then igniting the fuel-air mixture through the compression process (as is done in current diesel engines). The combustion occurring in an HCCI engine is fundamentally different from a spark-ignition or Diesel engine in that the heat release occurs as a global autoignition process, as opposed to the turbulent flame propagation or mixing controlled combustion used in current engines. The advantage of this global autoignition is that the temperatures within the cylinder are uniformly low, yielding very low emissions of oxides of nitrogen (NO{sub x}, the chief precursors to photochemical smog). The inherent features of HCCI combustion allows for design of engines with efficiency comparable to, or potentially higher than, diesel engines. While HCCI engines have great potential, several technical barriers exist which currently prevent widespread commercialization of this technology. The most significant challenge is that the combustion timing cannot be controlled by typical in-cylinder means. Means of controlling combustion have been demonstrated, but a robust control methodology that is applicable to the entire range …

All planned National Ignition Facility (NIF) capsule targets except machined beryllium require a plastic mandrel upon which the ablator is applied. This mandrel must at least meet if not exceed the symmetry and surface finish requirements of the final capsule. The mandrels are produced by a two-step process. In the first step a thin-walled poly({alpha}-methylstyrene)(P{alpha}MS) shell is produced using microencapsulation techniques. This shell is overcoated with 10 to 15 {micro}m of glow discharge polymer (GDP) and then pyrolyzed at 300 C. This pyrolysis causes the P{alpha}MS to depolymerize to gas phase monomer that diffuses away through the more thermally stable plasma polymer shell, which retains all the symmetry of the original P{alpha}MS shell. Thus our challenge has been to produce 2-mm-diameter P{alpha}MS shells to serve as these initial ''decomposable'' mandrels that meet or exceed the current NIF design specifications. The basic microencapsulation process used in producing P{alpha}MS mandrels involves using a droplet generator to produce a water droplet (Wl) encapsulated by a fluorobenzene solution of P{alpha}MS (O), this compound droplet being suspended in a stirred aqueous bath (W2). Historically this bath has contained poly(vinyl alcohol) (PVA, 88% hydrolyzed, mol. wt. {approx}25,000 g/mol) to prevent agglomeration of the initially fluid compound …

This paper describes the design of the downstream beam transport line for the second axis of the Dual Axis Radiographic Hydrodynamic Test (DARHT-II) Facility. The DARHT-II project is a collaboration between LANL, LBNL and LLNL. DARHT II is a 18.4-MeV, 2000-Amperes, 2-{micro}sec linear induction accelerator designed to generate short bursts of x-rays for the purpose of radiographing dense objects. The downstream beam transport line is approximately 22-meter long region extending from the end of the accelerator to the bremsstrahlung target. The principal element of the beam transport section is the fast deflector, or kicker system, used to generate four micropulses from the primary accelerator beam. Within this proposed transport line there are also several conventional solenoid, quadrupole and dipole magnets which transport and focus the beam to the target and to the beam dumps.

Tungstophosphoric Acid (HPW) has been investigated using different spectroscopic and chemical techniques. Bulk sensitive techniques such as x-ray diffract ion (XRD) and infrared (IR) spectroscopy indicate that the acid is stable at temperatures as high as 300 degrees C or higher. However, our work suggests that HPW starts loosing stability at temperature as low as 200 degrees C. For instance, P 2p peak was not detected in the XPS spectrum of HPW preheated at 100 degrees C, but was clearly observed after preheating the acid at 200 degrees C and 400 degrees C. This suggests the destruction of the molecules of the surface leading to the enrichment of surface with phosphorus. These results may explain why HPW deactivates very fast, e.g., 8 min at 200 degrees C, in hexane cracking experiments. This could limit the use of HPW in surface reactions that even require moderate temperatures. Detailed infrared spectroscopic investigation of the HPW as a function of temperature showed a gradual in crease in absorbance of the W-O-W corner shared vibration relative to the absorbance of the other bands. This indicates that the symmetry, and hence the stability, of the molecule was decreased upon heating.
