A letter report issued by the Government Accountability Office with an abstract that begins "GAO is required to annually audit the financial statements of the Deposit Insurance Fund (DIF) and FSLIC Resolution Fund (FRF), which are administered by the Federal Deposit Insurance Corporation (FDIC). GAO is responsible for obtaining reasonable assurance about whether FDIC's financial statements for DIF and FRF are presented fairly in all material respects, in conformity with U.S. generally accepted accounting principles, and whether FDIC maintained effective internal control over financial reporting and compliance. Also, GAO is responsible for testing FDIC's compliance with selected laws and regulations. Created in 1933 to insure bank deposits and promote sound banking practices, FDIC plays an important role in maintaining public confidence in the nation's financial system. In 1989, legislation to reform the federal deposit insurance system created three funds to be administered by FDIC: the Bank Insurance Fund (BIF) and the Savings Association Insurance Fund (SAIF), which protect bank and savings deposits, and FRF, which was created to close out the business of the former Federal Savings and Loan Insurance Corporation. In accordance with subsequent legislation passed in 2006, FDIC merged the BIF and SAIF into the newly established DIF …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) industry personnel security clearance program has long-standing delays and backlogs in completing clearance requests and difficulties in accurately projecting its future needs for investigations to be conducted by the Office of Personnel Management (OPM). In 2006, Congress mandated that DOD report annually on the future requirements of the program and DOD's efforts to improve it, and that GAO evaluate DOD's first report. Specifically, GAO was required to report on (1) the extent to which the report responds to the issues in the mandate, (2) the number and cost of clearance investigations and adjudications in fiscal years 2000-2006, and (3) the extent to which DOD has developed procedures to estimate future needs, plans to reduce delays and backlogs, and plans to provide funding for the program. To accomplish these objectives, GAO obtained and reviewed laws, executive orders, policies, reports, and other documents related to the security clearance process and interviewed officials from a range of government offices concerned with the clearance process."

A letter report issued by the Government Accountability Office with an abstract that begins "Coal-fired power plants generate about one-half of the nation's electricity and about one-third of its carbon dioxide (CO2) emissions, which contribute to climate change. In 2003, the Department of Energy (DOE) initiated FutureGen--a commercial-scale, coal-fired power plant to incorporate integrated gasification combined cycle (IGCC), an advanced generating technology, with carbon capture and storage (CCS). The plant was to capture and store underground about 90 percent of its CO2 emissions. DOE's cost share was 74 percent, and industry partners agreed to fund the rest. Concerned about escalating costs, DOE restructured FutureGen. GAO was asked to examine (1) the original and restructured programs' goals, (2) similarities and differences between the new FutureGen and other DOE CCS programs, and (3) if the restructuring decision was based on sufficient information. GAO reviewed best practices for making programmatic decisions, FutureGen plans and budgets, and documents on the restructuring of FutureGen. GAO contacted DOE, industry partners, and experts."

A letter report issued by the General Accounting Office with an abstract that begins "As technological and other advances transform the U.S. economy, many of the nation's six million employers may have trouble finding employees with the skills to do their jobs well. Some experts indicate that such a skill gap already affects many employers. To help close this skill gap, both federal- and state-funded programs are providing training and helping employers find qualified employees. In 2002, the federal government spent about $12 billion on workforce programs, and there are various studies on these programs. States also raised revenues in 2002--from taxes levied on employers--to fund their own workforce programs. However, little is known about these state programs. GAO was asked to provide information on how many states use these employer taxes to fund their own employment placement and training programs, what services are provided, the extent to which these state programs coordinate with federal programs, and how states assess the performance of these programs."

A letter report issued by the Government Accountability Office with an abstract that begins "Americans receive care from tens of thousands of health care facilities participating in Medicare and Medicaid. To ensure the quality of care, CMS contracts with states to conduct periodic surveys and complaint investigations. Federal spending on such activities totaled about $444 million in fiscal year 2007; states are expected to contribute their own funds both through the Medicaid program and apart from that program. GAO evaluated survey funding, state workloads, and federal oversight of states' use of funds since fiscal year 2000 to determine if federal funding had kept pace with the changing workload. GAO analyzed (1) federal funding trends from fiscal years 2000 through 2007 and CMS's methodology for determining states' allocations and spending, (2) CMS data on the number of participating facilities and completed state surveys, and (3) CMS oversight of state spending. GAO interviewed state officials and collected data from 28 states."

A letter report issued by the General Accounting Office with an abstract that begins "The security of U.S. commercial aviation is a long-standing concern, and substantial efforts have been undertaken to strengthen it. One of these efforts is the development of a new Computer-Assisted Passenger Prescreening System (CAPPS II) to identify passengers requiring additional security attention. The development of CAPPS II has raised a number of issues, including whether individuals may be inappropriately targeted for additional screening, and whether data accessed by the system may compromise passengers' privacy. GAO was asked to determine (1) the development status and plans for CAPPS II; (2) the status of CAPPS II in addressing key developmental, operational, and public acceptance issues; and (3) other challenges that could impede the successful implementation of the system."

A letter report issued by the General Accounting Office with an abstract that begins "The Defense Threat Reduction Agency (DTRA), within the Department of Defense (DOD), plays a key role in addressing the threats posed by weapons of mass destruction (WMD). Since the September 11, 2001, attacks, the visibility of DTRA's role has increased as federal agencies and military commanders have looked to the agency for additional support and advice. GAO was asked to report on DTRA's (1) mission and the efforts it undertakes to fulfill this mission; (2) relationship with other government entities, specifically the Department of Energy and the Department of Homeland Security (DHS); and (3) process that it uses to prioritize resources and assess progress toward organizational goals."

A letter report issued by the General Accounting Office with an abstract that begins "The U.N. Secretary General launched two reform agendas, in 1997 and 2002, to address the U.N.'s core management challenges--poor leadership of the Secretariat, duplication among its many offices and programs, and the lack of accountability for staff performance. In 2000, GAO reported that the Secretary General had reorganized the Secretariat's leadership and structure, but that the reforms were not yet complete. As the largest financial contributor to the United Nations, the United States has a strong interest in the completion of these reforms. GAO was asked to assess the (1) overall status of the 1997 and 2002 reforms, (2) implementation of reforms in four key areas, and (3) potential challenges to reform."

A letter report issued by the General Accounting Office with an abstract that begins "For years, some states have taken advantage of a loophole in Medicaid law that allows them to claim billions of dollars in excessive federal matching funds by exploiting the "upper payment limit" (UPL), which is intended to be a ceiling on federal cost sharing. Congress and the Centers for Medicare & Medicaid Services (CMS) acted to curtail UPL financing schemes through law in 2000 and regulation in 2001. CMS recognized that some states had developed a long-standing reliance on UPL funds. The law and regulation authorized transition periods of up to 8 years for states to phase out excessive UPL claims. GAO was asked to examine CMS's oversight of nursing home UPL arrangements, including the status of and the basis for transition period decisions."

A letter report issued by the General Accounting Office with an abstract that begins "In recent years, the challenges of aging populations have become a topic of increasing concern to the developed nations. These challenges range from the fiscal imbalance in national pension systems caused by fewer workers having to provide benefits for greater numbers of retirees, to potential economic strains due to shortages of skilled workers. Part of the solution to these challenges could be greater older worker labor force participation. GAO identified three nations--Japan, Sweden, and the United Kingdom--that had displayed high levels of older worker labor force participation in the past and were now implementing policy reforms that continued to emphasize the importance of older workers. The experiences of these nations suggest that the nature of the reforms, the public availability and transparency of information on the reforms, and the strength of the national economy play key roles in extending older worker labor force participation."

A letter report issued by the General Accounting Office with an abstract that begins "As we face the challenges of the 21st century, the federal government must strive to build high-performing organizations. Nothing less than a fundamental transformation in the people, processes, technology, and environment used by federal agencies to address public goals will be necessary to address public needs. In high-performing organizations, management controls, processes, practices, and systems are adopted that are consistent with prevailing best practices and contribute to concrete organizational results. Ultimately, however, the federal government needs to change its culture to become more results-oriented, client- and customer-focused, and collaborative in nature. On November 6, 2003, GAO hosted a forum to discuss what it means for a federal agency to be high-performing in an environment where results and outcomes are increasingly accomplished through partnerships that cut across different levels of government and different sectors of the economy. The forum included discussions of the metrics, means, and mechanisms that a federal agency should use to optimize its influence and contribution to nationally important results and outcomes. The forum included representatives of the public, not-for-profit, and for-profit sectors as well as academia who are knowledgeable of what it takes …

The chemical element potassium is an essential mineral in people and is subject to homeostatic regulation. Natural potassium comprises three isotopes, 39K, 40K, and 41K. Potassium-40 is radioactive, with a half life of 1.248 billion years. In most transitions, it emits a β particle with a maximum energy of 0.560 MeV, and sometimes a gamma photon of 1.461 MeV. Because it is ubiquitous, 40K produces radiation dose to all human beings. This report contains the results of new measurements of 40K in 248 adult females and 2,037 adult males performed at the Department of Energy Hanford Site in 2006 and 2007. Potassium concentrations diminish with age, are generally lower in women than in men, and decrease with body mass index (BMI). The average annual effective dose from 40K in the body is 0.149 mSv y−1 for men and 0.123 mSv y−1 women respectively. Averaged over both men and women, the average effective dose per year is 0.136 mSv y−1. Calculated effective doses range from 0.069 to 0.243 mSv y−1 for adult males, and 0.067 to 0.203 mSv y−1 for adult females, a roughly three-fold variation for each gender. The need for dosimetric phantoms with a greater variety of BMI values …

Total organic halogen (TOX) is used as a parameter to screen groundwater samples at the Hanford Site. Trending is done for each groundwater well, and changes in TOX and other screening parameters can lead to costly changes in the monitoring protocol. The Waste Sampling and Characterization Facility (WSCF) analyzes groundwater samples for TOX using the United States Environmental Protection Agency (EPA) SW-S46 method 9020B (EPA 1996a). Samples from the Soil and Groundwater Remediation Project (SGRP) are submitted to the WSCF for analysis without information regarding the source of the sample; each sample is in essence a ''blind'' sample to the laboratory. Feedback from the SGRP indicated that some of the WSCF-generated TOX data from groundwater wells had a number of outlier values based on the historical trends (Anastos 200Sa). Additionally, analysts at WSCF observed inconsistent TOX results among field sample replicates. Therefore, the WSCF lab performed an investigation of the TOX analysis to determine the cause of the outlier data points. Two causes were found that contributed to generating out-of-trend TOX data: (1) The presence of inorganic chloride in the groundwater samples: at inorganic chloride concentrations greater than about 10 parts per million (ppm), apparent TOX values increase with increasing …

The performance of a glass used for immobilization of high-level nuclear waste (HLW) is generally quantified by its resistance to chemical degradation, or durability. The durability of a HLW glass is dependent on its composition. If crystalline phases form within a glass during cooling, the composition of the residual glass network is altered, therefore affecting the durability of the glass. Crystallization of nepheline (NaAlSiO{sub 4}) has been shown to adversely impact the durability of HLW glasses since it removes glass forming species (in this case, Al and Si) from the glass network. The propensity for nepheline crystallization in a HLW glass increases with increasing concentrations of Al{sub 2}O{sub 3} and Na{sub 2}O in the glass. Nepheline crystallization is therefore of concern for processing of HLW at the Defense Waste Processing Facility (DWPF) since the sludge waste streams at the Savannah River Site (SRS) can contain high concentrations of Al{sub 2}O{sub 3} and Na{sub 2}O. Currently, a 'nepheline discriminator' is included as a process control constraint at the DWPF. The nepheline discriminator relates the concentrations of SiO{sub 2}, Na{sub 2}O and Al{sub 2}O{sub 3} (as weight percentages in glass) to a critical value of 0.62. The discriminator defines a boundary line …

During robot path planning and control the equations that describe the robot motions are determined and solved. Historically these expressions were derived analytically off-line. For robots that must adapt to their environment or perform a wide range of tasks, a way is needed to rapidly re-derive these expressions to take into account the robot kinematic changes, such as when a tool is added to the end-effector. The JFKengine software was developed to automatically produce the expressions representing the manipulator arm motion, including the manipulator arm Jacobian and the forward kinematic expressions. Its programming interface can be used in conjunction with robot simulation software or with robot control software. Thus, it helps to automate the process of configuration changes for serial robot manipulators. If the manipulator undergoes a geometric change, such as tool acquisition, then JFKengine can be invoked again from the control or simulation software, passing it parameters for the new arm configuration. This report describes the automated processes that are implemented by JFKengine to derive the kinematic equations and the programming interface by which it is invoked. Then it discusses the tree data structure that was chosen to store the expressions, followed by several examples of portions of expressions …

NERI Project No.2000-0109 began in August 2000 and has three tasks. The first project year addressed Task 1, namely development of nonlinear prognostication for critical equipment in nuclear power facilities. That work is described in the first year's annual report (ORNLTM-2001/195). The current (second) project year (FY02) addresses Task 2, while the third project year will address Tasks 2-3. This report describes the work for the second project year, spanning August 2001 through August 2002, including status of the tasks, issues and concerns, cost performance, and status summary of tasks. The objective of the second project year's work is a compelling demonstration of the nonlinear prognostication algorithm using much more data. The guidance from Dr. Madeline Feltus (DOE/NE-20) is that it would be preferable to show forewarning of failure for different kinds of nuclear-grade equipment, as opposed to many different failure modes from one piece of equipment. Long-term monitoring of operational utility equipment is possible in principle, but is not practically feasible for the following reason. Time and funding constraints for this project do not allow us to monitor the many machines (thousands) that will be necessary to obtain even a few failure sequences, due to low failure rates (<10{sup …

This project was intended to advance the science of surface bonding in order to provide the functionality demanded by target fabrication requirements, as well as similar needs in other fields of importance to LLNL. We have developed and demonstrated a very powerful capability, i.e. 'single molecule force spectroscopy', that allows the strength of individual chemical bonds to be measured. This project focused on long chain molecules that are covalently bound to surfaces on one end and have complementary reactive groups that have the potential for bridging between surfaces. In biological systems, long chain tethers provide the mechanism for adhesion between dissimilar surfaces, e.g. bacteria adhesion to cells, and were found useful for developing the methodology. Polymer tethers offer the means to bridge across finite surface roughness and have the potential of forming thin, well-characterized bonds on a variety of surfaces.

The goal of this project is to measure transport through CNTs and study effects of confinement at molecular scale. This work is motivated by several simulation papers in high profile journals that predict significantly higher transport rates of gases and liquids through carbon nanotubes as compared with similarly-sized nanomaterials (e.g. zeolites). The predictions are based on the effects of confinement, atomically smooth pore walls and high pore density. Our work will provide the first measurements that would compare to and hopefully validate the simulations. Gas flux is predicted to be >1000X greater for SWNTs versus zeolitesi. A high flux of 6-30 H2O/NT/ns {approx} 8-40 L/min for a 1cm{sup 2} membrane is also predicted. Neutron diffraction measurements indicate existence of a 1D water chain within a cylindrical ice sheet inside carbon nanotubes, which is consistent with the predictions of the simulation. The enabling experimental platform that we are developing is a semipermeable membrane made out of vertically aligned carbon nanotubes with gaps between nanotubes filled so that the transport occurs through the nanotubes. The major challenges of this project included: (1) Growth of CNTs in the suitable vertically aligned configuration, especially the single wall carbon nanotubes; (2) Development of a process …

This report is the second in a series detailing the procedures used and the results obtained from studies designed to determine the impacts of erosion control structures on fish habitat at Willapa Bay, Washington. The erosion control structure, consisting of a 1600-ft rock groin and an attached 930-ft underwater dike was placed on Washaway Beach in 1998 to protect State Route (SR) 105 from erosion. The objectives of the study are to develop an understanding about whether groin-type structures on the outer coast can alter migratory movement or predation pressure on juvenile and adult salmon. Field surveys in this report were conducted from October 14-21, 2001, and consisted of gillnetting, passive drifter surveys, diver surveys, interviews with fishers and Washington Department of Fish and Wildlife (WDFW) personnel, bird and mammal surveys, and split beam hydroacoustic surveys. Field sampling activities were begun on October 14 and were suspended during the commercial gillnet season from October 16-18. Interviews with fishers and WDFW were conducted during that period, and field sampling recommenced on October 19. The hydroacoustic surveys were conducted from October 19-21. The migration pattern of fish, presumed to be salmon, was documented relative to the tidal phase. Fish were observed to …
