A letter report issued by the General Accounting Office with an abstract that begins "Recent legislative and regulatory changes have blurred some distinctions between credit unions and other depository institutions such as banks. The 1998 Credit Union Membership Access Act (CUMAA) allowed for an expansion of membership and mandated safety and soundness controls similar to those of other depository institutions. In light of these changes and the evolution of the credit union industry, GAO evaluated (1) the financial condition of the industry and the deposit (share) insurance fund, (2) the impact of CUMAA on the industry, and (3) how the National Credit Union Administration (NCUA) had changed its safety and soundness processes."

A letter report issued by the Government Accountability Office with an abstract that begins "The Economic Development Administration (EDA) Reauthorization Act of 2004 (P. L. 108-373) included a requirement that GAO evaluate grants made by EDA for the economic development of brownfield sites. More than 450,000 brownfield sites--properties where redevelopment or reuse may be complicated by real or perceived environmental contamination--are scattered across the United States. This report discusses specifics of grants made by EDA at brownfields sites, including (1) the types, extent, and amount of EDA funds used for remediation activities; (2) the environmental standards and agencies involved; and (3) the economic development activities, standards, and impact."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) operations in time of war or national emergency depend on sizeable reserve force involvement and DOD expects future use of the reserve force to remain high. Operational readiness depends on healthy and fit personnel. Long-standing problems have been identified with reserve members not being in proper medical or physical condition. Drilling members in the reserve force by law are required to have a medical exam every 5 years and an annual certificate of their medical status. Also, DOD policies require an annual dental exam and an annual evaluation of physical fitness. Compliance with these routine requirements is the first step in determining who is fit for duty. Public Law 108-375 required GAO to study DOD's management of the health status of reserve members activated for Operations Enduring Freedom and Iraqi Freedom. GAO assessed DOD's (1) ability to determine reserve force compliance with routine exams, and (2) visibility over reserve members' health status after they are called to duty and the care, if any, provided to those deployed with preexisting conditions."

A letter report issued by the Government Accountability Office with an abstract that begins "Trade in business, professional, and technical (BPT) services associated with offshoring needs to be accurately tracked, but a gap exists between U.S. and Indian data. The extent of and reasons for this gap are important to understand in order to address questions about the magnitude of offshoring and to analyze its future development. Under the authority of the Comptroller General of the United States, and as part of a body of GAO work on the issue of offshoring of services, this report (1) describes the extent of the gap between U.S. and Indian data, (2) identifies factors that contribute to the difference between the two countries' data, and (3) examines the challenges the United States has faced in collecting services trade data. GAO has addressed this report to the congressional committees of jurisdiction."

A letter report issued by the General Accounting Office with an abstract that begins "Members of Congress periodically have expressed interest in converting the federal budget process from an annual to a biennial cycle. Congress believes that the time spent on these activities has come at the expense of congressional oversight and authorization responsibilities. To better understand states' experiences with the biennial budget cycle, GAO studied three states: Arizona, Ohio, and Connecticut. GAO found that the states' reasons for changing their budget cycles varied. For example, Arizona adopted a biennial cycle to increase legislative oversight and reduce time spent on the budget. Connecticut adopted it as part of a fiscal reform effort. To execute a biennial budget successfully, the states' experiences suggest that the legislative and executive branches must agree on how the off-year budget process will work. Different approaches to managing the off-year budget have been developed by states, including establishing formal guidelines for off-year budget changes and relying on leadership control. Efforts to increase legislative oversight in the off-year by converting to a biennial budget process may be difficult. Ohio and Connecticut officials said they that have not increased legislative oversight in the off-year, and Arizona officials said …

A letter report issued by the General Accounting Office with an abstract that begins "As the steward of taxpayer dollars, the federal government is accountable for how its agencies and grantees spend funds. It is also responsible for safeguardingagainst improper payments, which include payments that should not have been madeor were made for incorrect amounts irrespective of whether the agency had effective controls in place. Reported estimates of improper payments total billions ofdollars annually. With billions of dollars at risk, agencies need to vigilantly safeguard those resources entrusted to them and assign a high priority to reducing fraud, waste, and abuse. In their fiscal year 1999 financial statement, 12federal agencies reported improper payments totalling $20.7 billion. A first step for some agencies will be to assess programs at risk and develope ways to identify, estimate, and report the nature and extent of improper payments annually. Without this fundamental knowledge, agencies will not be fully informed about the magnitude, trends, and types of payment errors occurring within their programs. Furthermore, most agencies will not be able to make informed cost-benefit decisions about strengthening their internal controls to minimize future improper payments or effectively develop goals and strategies to reduce them. In …

A letter report issued by the General Accounting Office with an abstract that begins "Public health experts have raised concerns about the ability of the nation's public health system to detect and respond to emerging infectious disease threats, such as pandemic influenza. Although vaccines are considered the first line of defense to prevent or reduce influenza-related illness and death, GAO found that they may be unavailable, in short supply, or ineffective for some portions of the population during the first wave of a pandemic. Federal and state influenza pandemic plans are in various stages of completion and do not completely or consistently address key issues surrounding the purchase, distribution, and administration of vaccines and antiviral drugs. Inconsistencies in state and federal policies could contribute to public confusion and weaken the effectiveness of the public health response."

A letter report issued by the General Accounting Office with an abstract that begins "In 1996 and 1999, Congress authorized the U.S. Army Corps of Engineers (the Corps) to strengthen sections of the American River and Natomas Basin levees that provide flood protection for Sacramento, California. In 2002, the Corps reported that the cost of this work, known as the Common Features Project, had increased significantly. GAO was asked to determine why costs increased, the extent to which the Corps analyzed and reported the potential cost increases to Congress in a timely manner, and whether the Corps correctly estimated economic benefits."

A letter report issued by the Government Accountability Office with an abstract that begins "To document the interactions of aliens with the Department of Homeland Security's (DHS) United States Citizenship and Immigration Services (USCIS) and other government entities, USCIS creates alien files, or A-files. While deemed critical, especially in making citizenship decisions, A-files are sometimes missing during adjudications. In 2002, naturalization was granted to an alien whose A-file was missing and who was later found to be associated with a terrorist organization. GAO focused its review on (1) how often USCIS adjudicates naturalization applications without an A-file and why, (2) the effect that missing A-files can have on the adjudication process, and (3) steps taken to help mitigate the risk of missing A-files. To address these questions, GAO interviewed officials and staff from USCIS and reviewed relevant data, policies, and procedures related to processing naturalization applications and the automated file-tracking system DHS established to track the movement of A-files."

The original software package TRLan, [TRLan User Guide], page 24, implements the thick restart Lanczos method, [Wu and Simon 2001], page 24, for computing eigenvalues {lambda} and their corresponding eigenvectors v of a symmetric matrix A: Av = {lambda}v. Its effectiveness in computing the exterior eigenvalues of a large matrix has been demonstrated, [LBNL-42982], page 24. However, its performance strongly depends on the user-specified dimension of a projection subspace. If the dimension is too small, TRLan suffers from slow convergence. If it is too large, the computational and memory costs become expensive. Therefore, to balance the solution convergence and costs, users must select an appropriate subspace dimension for each eigenvalue problem at hand. To free users from this difficult task, nu-TRLan, [LNBL-1059E], page 23, adjusts the subspace dimension at every restart such that optimal performance in solving the eigenvalue problem is automatically obtained. This document provides a user guide to the nu-TRLan software package. The original TRLan software package was implemented in Fortran 90 to solve symmetric eigenvalue problems using static projection subspace dimensions. nu-TRLan was developed in C and extended to solve Hermitian eigenvalue problems. It can be invoked using either a static or an adaptive subspace dimension. In …

This report identifies additional bills that have been introduced in the 109th Congress to address specific concerns related to how the Endangered Species Act (ESA is implemented and how endangered species are managed, and will be updated periodically to reflect legislative action.

This report provides information about the Corporate "Inversions" and "Expatriation" on Firms That Incorporate Abroad for Tax Purposes where increasing number of U.S firms have altered their structure by substituting a foreign parent corporation for a domestic one.

As highlighted by the Social Security Administration (SSA), the aging of the (United States) population, hastened by the impending retirement of the huge baby-boom generation, has caused policy-makers to question whether the U.S. Social Security system can meet the demands for retirement benefits in the future. Because the current system largely pays benefits through taxes paid by current workers, the financial health of the system is sensitive to the ratio of dependents to workers—sometimes called the age dependency ratio or support ratio. Trends and projections of dependency ratios, including the relationship between both older (years 65 and older) and younger (under age 20) dependents to the working-age population in the United States are considered in the first section of this demographic report. Next, the United States is compared to nine other nations, including the seven other members of the G8. In the final section, policy implications of the changing dependent-to-worker ratios are considered in the context of pay-as-you-go (paygo) social security systems.

This report describes work performed during the initial period of the project “Probabilistic Risk Based Decision Support for Oil and Gas Exploration and Production Facilities in Sensitive Ecosystems.” The specific region that is within the scope of this study is the Fayetteville Shale Play. This is an unconventional, tight formation, natural gas play that currently has approximately 1.5 million acres under lease, primarily to Southwestern Energy Incorporated and Chesapeake Energy Incorporated. The currently active play encompasses a region from approximately Fort Smith, AR east to Little Rock, AR approximately 50 miles wide (from North to South). The initial estimates for this field put it almost on par with the Barnett Shale play in Texas. It is anticipated that thousands of wells will be drilled during the next several years; this will entail installation of massive support infrastructure of roads and pipelines, as well as drilling fluid disposal pits and infrastructure to handle millions of gallons of fracturing fluids. This project focuses on gas production in Arkansas as the test bed for application of proactive risk management decision support system for natural gas exploration and production. The activities covered in this report include meetings with representative stakeholders, development of initial content …

Ultrasonic nondestructive evaluation (NDE) and inspection of cast austenitic stainless steel (CASS) components used in the nuclear power industry is neither as effective nor reliable as is needed due to detrimental effects upon the interrogating ultrasonic beam and interference from ultrasonic backscatter. The root cause is the coarse-grain microstructure inherent to this class of materials. Some ultrasonic techniques perform better for particular microstructural classifications and this has led to the hypothesis that an ultrasonic inspection can be optimized for a particular microstructural class, if a technique exists to reliably classify the microstructure for feedback to the inspection. This document summarizes scoping experiments of in-situ ultrasonic methods for classification and/or characterization of the material microstructures in CASS components from the outside surface of a pipe. The focus of this study was to evaluate ultrasonic methods and provide an interim report that documents results and technical progress. An initial set of experiments were performed to test the hypothesis that in-service characterization of cast austenitic stainless steel (CASS) is feasible, and that, if reliably performed, such data would provide real-time feedback to optimize in-service inspections in the field. With this objective in mind, measurements for the experiment were restricted to techniques that should …

Energy required for water heating accounts for approximately 40percent of national residential natural gas consumption in California. With water heating contributing such a substantial portion of natural gas consumption, it is important to pay attention to water heater efficiencies. This paper reports on an investigation of a patented, buoyancy-operated flue damper. It is an add-on design to a standard atmospherically vented natural-draft gas-fired storage water heater. The flue damper was expected to reduce off-cycle standby losses, which would lead to improvements in the efficiency of the water heater. The test results showed that the Energy Factor of the baseline water heater was 0.576. The recovery efficiency was 0.768. The standby heat loss coefficient was 10.619 (BTU/hr-oF). After the damper was installed, the test results show an Energy Factor for the baseline water heater of 0.605. The recovery efficiency was 0.786. The standby heat loss coefficient was 9.135 (BTU/hr-oF). The recovery efficiency increased 2.3percent and the standby heat loss coefficient decreased 14percent. When the burner was on, the baseline water heater caused 28.0 CFM of air to flow from the room. During standby, the flow was 12.4 CFM. The addition of the damper reduced the flow when the burner was on …

This report discusses the simulant preparation procedure for producing multi-component simulants for leaching and filtration studies, including development and comparison activities in accordance with the test plan( ) prepared and approved in response to the Test Specification 24590-WTP-TSP-RT-06-006, Rev 0 (Smith 2006). A fundamental premise is that this approach would allow blending of the different components to simulate a wide variety of feeds to be treated in the Hanford Tank Waste Treatment and Immobilization Plant (WTP). For example, a given feed from the planned feed vector could be selected, and the appropriate components would then be blended to achieve a representation of that particular feed. Using the blending of component simulants allows the representation of a much broader spectrum of potential feeds to the Pretreatment Engineering Platform (PEP).

Pleotint has embarked on a novel approach with our Sunlight Responsive Thermochromic, SRT™, windows. We are integrating dynamic sunlight control, high insulation values and low solar heat gain together in a high performance window. The Pleotint SRT window is dynamic because it reversibly changes light transmission based on thermochromics activated directly by the heating effect of sunlight. We can achieve a window package with low solar heat gain coefficient (SHGC), a low U value and high insulation. At the same time our windows provide good daylighting. Our innovative window design offers architects and building designers the opportunity to choose their desired energy performance, excellent sound reduction, external pane can be self-cleaning, or a resistance to wind load, blasts, bullets or hurricanes. SRT windows would provide energy savings that are estimated at up to 30% over traditional window systems. Glass fabricators will be able to use existing equipment to make the SRT window while adding value and flexibility to the basic design. Glazing installers will have the ability to fit the windows with traditional methods without wires, power supplies and controllers. SRT windows can be retrofit into existing buildings,

C1 chemistry refers to the conversion of simple carbon-containing materials that contain one carbon atom per molecule into valuable products. The feedstocks for C1 chemistry include natural gas, carbon dioxide, carbon monoxide, methanol and synthesis gas (a mixture of carbon monoxide and hydrogen). Synthesis gas, or syngas, is produced primarily by the reaction of natural gas, which is principally methane, with steam. It can also be produced by gasification of coal, petroleum coke, or biomass. The availability of syngas from coal gasification is expected to increase significantly in the future because of increasing development of integrated gasification combined cycle (IGCC) power generation. Because of the abundance of remote natural gas, the advent of IGCC, and environmental advantages, C1 chemistry is expected to become a major area of interest for the transportation fuel and chemical industries in the relatively near future. The CFFLS will therefore perform a valuable national service by providing science and engineering graduates that are trained in this important area. Syngas is the source of most hydrogen. Approximately 10 trillion standard cubic feet (SCF) of hydrogen are manufactured annually in the world. Most of this hydrogen is currently used for the production of ammonia and in a variety …
