Testimony issued by the General Accounting Office with an abstract that begins "In January, we issued our Performance and Accountability Series on management challenges and program risks at major agencies, including the U.S. Department of Agriculture (USDA). The report for USDA focused on a number of major management challenges, including enhancing financial management, and continued the high risk designation for Forest Service financial management. For many years, USDA struggled to improve its financial management activities, but inadequate accounting systems and related procedures and controls hampered its ability to get a clean opinion on its financial statements. After eight consecutive disclaimers of opinion, USDA's Office of Inspector General issued an unqualified opinion on USDA's fiscal year 2002 financial statements and reported that significant progress had been made in improving overall financial management. For each of USDA's agencies that prepared separate financial statements for fiscal year 2002, the audit opinions were also positive. Specifically, unqualified audit opinions were issued on the financial statements of the Forest Service, Federal Crop Insurance Corporation/Risk Management Agency, Commodity Credit Corporation, the Rural Development mission area, and the Rural Telephone Bank. While we consider these clean opinions a positive step, some of these could not have been …

A letter report issued by the General Accounting Office with an abstract that begins "Janet Rehnquist became the Inspector General of the Department of Health and Human Services (HHS) in August 2001. GAO was asked to conduct a review of the Inspector General's organization and assess her leadership, independence, and judgment in carrying out the mission of the Office of Inspector General (OIG). GAO examined indicators of the OIG's productivity and compared them to the organization's past performance. GAO also determined whether employee morale has been sustained by surveying all OIG employees and comparing the results to those obtained through an identical survey administered in 2002. On March 4, 2003, the Inspector General resigned her office effective June 1, 2003. However, in this report we refer to Ms. Rehnquist as the Inspector General."

A letter report issued by the General Accounting Office with an abstract that begins "Each year, the Department of Defense (DOD) spends billions of dollars to house unmarried junior enlisted servicemembers, primarily in military barracks. Over the next several years, the Army, Navy, and Air Force plan to spend about $6 billion to eliminate barracks with multi-person bathroom facilities and provide private sleeping rooms for all permanent party members. Given the cost of the program, GAO looked at (1) the status of efforts to examine the potential for private sector financing, ownership, operation, and maintenance of military barracks; (2) the opportunity to reduce the construction costs of barracks through widespread use of residential construction practices; and (3) whether opportunities exist to make better use of existing barracks."

A letter report issued by the General Accounting Office with an abstract that begins "A 1981 U.S. District Court decision found that the Drug Enforcement Administration (DEA) had discriminated against African American special agents in a number of personnel practices. Over the years, the plaintiffs and DEA had agreed to remedies in many of these areas. However, minority representatives continued to raise issues in three areas--hiring, promotion, and discipline. GAO was asked to examine DEA's current processes for hiring, promoting, and disciplining special agents, and provide information about racial, ethnicity, and gender differences in these three areas."

A letter report issued by the General Accounting Office with an abstract that begins "Ninety-three U.S. Attorneys serve 94 judicial districts (the same U.S. Attorney serves the District of Guam and the District of the Northern Mariana Islands) under the direction of the Attorney General. Among other things, the Attorney General expects U.S. Attorneys to lead or be involved with the community in preventing and controlling crime including efforts to secure Department of Justice (DOJ) grant funds and work with grantees. This report provides information about the guidance U.S. Attorneys are given in carrying out their responsibilities with regard to DOJ grants. It makes recommendations to assess compliance with guidance and to reduce the potential for conflicts of interest."

Testimony issued by the General Accounting Office with an abstract that begins "In its 2003 performance and accountability report on the Department of Education, GAO identified challenges in, among other areas, student financial aid programs and financial management. The information GAO presents in this testimony is intended to assist Congress in assessing Education's progress in addressing and overcoming these challenges. GAO is not making new recommendations in this testimony, but past reports have made specific recommendations aimed at addressing some of these major management challenges."

Testimony issued by the General Accounting Office with an abstract that begins "Geographic information systems (GIS) manipulate, analyze, and graphically present an array of information associated with geographic locations, have been invaluable to all levels of government. Their usefulness in disaster response was recently demonstrated during the Space Shuttle Columbia recovery effort. GIS provided precise maps and search grids to guide crews to the debris that was strewn across 41 counties in Texas and Louisiana. The federal government has long been attempting to develop an integrated nationwide GIS network. The information available through such a network could significantly enhance decision--making in myriad public--service areas, including emergency response, national security, law enforcement, health care, and the environment. Among GAO's objectives were to describe the federal government's efforts to coordinate GIS activities, the long-standing challenges of adopting and implementing federal GIS standards, and the role of Geospatial One-Stop."

Millions of people suffering from diseases such as retinitis pigmentosa and macular degeneration are legally blind due to the loss of photoreceptor function. Fortunately a large percentage of the neural cells connected to the photoreceptors remain viable, and electrical stimulation of these cells has been shown to result in visual perception. These findings have generated worldwide efforts to develop a retinal prosthesis device, with the hope of restoring vision. Advances in microfabrication, integrated circuits, and wireless technologies provide the means to reach this challenging goal. This dissertation describes the development of innovative silicone-based microfabrication techniques for producing an implantable microelectrode array. The microelectrode array is a component of an epiretinal prosthesis being developed by a multi-laboratory consortium. This array will serve as the interface between an electronic imaging system and the human eye, directly stimulating retinal neurons via thin film conducting traces. Because the array is intended as a long-term implant, vital biological and physical design requirements must be met. A retinal implant poses difficult engineering challenges due to the size of the intraocular cavity and the delicate retina. Not only does it have to be biocompatible in terms of cytotoxicity and degradation, but it also has to be structurally …

Supplementary data are also included regarding the sediment and solution characteristic used in the studies. The original document compiles in a single source the Kd values measured with Hanford sediment for radionuclides and toxic compounds that have the greatest potential for driving risk to human health and safety in the vadose zone and groundwater at the Hanford Site.

This document presents the vision for Brookhaven National Laboratory (BNL) for the next five years, and a roadmap for implementing that vision. Brookhaven is a multidisciplinary science-based laboratory operated for the U.S. Department of Energy (DOE), supported primarily by programs sponsored by the DOE's Office of Science. As the third-largest funding agency for science in the U.S., one of the DOE's goals is ''to advance basic research and the instruments of science that are the foundations for DOE's applied missions, a base for U.S. technology innovation, and a source of remarkable insights into our physical and biological world, and the nature of matter and energy'' (DOE Office of Science Strategic Plan, 2000 http://www.osti.gov/portfolio/science.htm). BNL shapes its vision according to this plan.

An immediate EM science need is a reliable kinetic model that predicts long-term waste glass performance. A framework for which the kinetics of mineral-solution reactions can be used to interpret complex silicate glass properties is required to accurately describe the current and future behavior of glasses as synthetic monoliths or natural analogs. Reaction rates and mechanisms are essential elements in deciphering mineral/material reactivity trends within a compositional series or across a matrix of complex solution compositions. An essential place to start, and the goal of this research, is to quantify the reactivity of crystalline and amorphous SiO2 phases in the complex fluids of natural systems.

Last year's paper by Bell and Gray [1] examined past trends in high performance computing and asserted likely future directions based on market forces. While many of the insights drawn from this perspective have merit and suggest elements governing likely future directions for HPC, there are a number of points put forth that we feel require further discussion and, in certain cases, suggest alternative, more likely views. One area of concern relates to the nature and use of key terms to describe and distinguish among classes of high end computing systems, in particular the authors use of ''cluster'' to relate to essentially all parallel computers derived through the integration of replicated components. The taxonomy implicit in their previous paper, while arguable and supported by some elements of our community, fails to provide the essential semantic discrimination critical to the effectiveness of descriptive terms as tools in managing the conceptual space of consideration. In this paper, we present a perspective that retains the descriptive richness while providing a unifying framework. A second area of discourse that calls for additional commentary is the likely future path of system evolution that will lead to effective and affordable Petaflops-scale computing including the future role …

Over 16,700 hours of operational experience was gained for the Oxygen Transport Membrane (OTM) elements of the proposed SOFC/OTM zero-emission power generation concept. It was repeatedly demonstrated that OTMs with no additional oxidation catalysts were able to completely oxidize the remaining depleted fuel in a simulated SOFC anode exhaust at an O{sub 2} flux that met initial targets. In such cases, neither residual CO nor H{sub 2} were detected to the limits of the gas chromatograph (<10 ppm). Dried OTM afterburner exhaust streams contained up to 99.5% CO{sub 2}. Oxygen flux through modified OTMs was double or even triple that of the standard OTMs used for the majority of testing purposes. Both the standard and modified membranes in laboratory-scale and demonstration-sized formats exhibited stable performance over extended periods (2300 to 3500 hours or 3 to 5 months). Reactor contaminants, were determined to negatively impact OTM performance stability. A method of preventing OTM performance degradation was developed and proven to be effective. Information concerning OTM and seal reliability over extended periods and through various chemical and thermal shocks and cycles was also obtained. These findings were used to develop several conceptual designs for pilot (10 kWe) and commercial-scale (250 kWe) SOFC/OTM …

Studies of thermally emitted electron Bernstein waves (EBWs) on CDX-U and NSTX, via mode conversion (MC) to electromagnetic radiation, support the use of EBWs to measure the Te profile and provide local electron heating and current drive (CD) in overdense spherical torus plasmas. An X-mode antenna with radially adjustable limiters successfully controlled EBW MC on CDX-U and enhanced MC efficiency to {approx} 100%. So far the X-mode MC efficiency on NSTX has been increased by a similar technique to 40-50% and future experiments are focused on achieving * 80% MC. MC efficiencies on both machines agree well with theoretical predictions. Ray tracing and Fokker-Planck modeling for NSTX equilibria are being conducted to support the design of a 3 MW, 15 GHz EBW heating and CD system for NSTX to assist non-inductive plasma startup, current ramp up, and to provide local electron heating and CD in high beta NSTX plasmas.
