The effects of seismic vibrations on the dynamic behavior of a composite system were analyzed. The equations of motion were derived and soIved with special emphasis on determining the resulting stresses. The method of analysis thus developed was applied to the composite structure consisting of the core, pressure vessel, and supporting skirt of the Experimental Gas-Cooled Reactor (EGCR). A system with three degrees of freedom was considered in order to determine the effects of an earthquake of the maximum intensity expected in the area surrounding Oak Ridge, Tennessee. The system of equations of motion was solved both numerically and analytically, and the resonant frequencies were determined. The seismic effect was shown to be small when the frequency of the seismic disturbance coincided with a natural frequency of the system. In particular, the shear stresses in the graphite core were shown to be negligible. (auth)

The results of our assessment of the processing methods and costs for the recovery of cesium, techneium, rhodium, and palladium from aged waste supernates are presented. Guidelines for the assessment of costs are given. Cesium can be readily absorbed from alkaline waste supernates without prior treatment using Linde AW-500, a synthetic zolite. Technetium, present in the supernate as the pertechnetate anion, together with rhodium and palladium, probably present as anionic nitrite complexes, can be absorbed from untreated waste supernates using Dowex 1-X4 or similar anion resins. Although the behavior of cesium and technetium is reasonably well understood, the behavior of the anionic complex that accounts for the presence of rhodium and palladium in this strongly alkaline solution is not well understood. Further work is required before a process can be outlined for the clean separation of rhodium and palladium from the technetium-rhodium-palladium crude fraction sorbed on the anion resin. An assessment of capital and operating costs for the recovery of cesium only, technetium only, or both cesium and technetium are tabulated. No costs are shown for rhodium and palladium, since the technology for their separation is not sufficiently advanced. However, the incremental cost for their separation from technetium is expected …

A new attempt is made to study the mechanisms of particle invasions into porous media. The following subjects are described: A critical survey of the literature indicating that the mechanism of particle invasions is not known in sufficient detail. The pros and cons of existing particle measuring devices are briefly described. Results from a new laboratory study on particle characterizations are given. The results of the laboratory studies on the flow of particle suspensions through porous media (up to 200 md) are discussed. The effects of flow rate and particle concentrations on the amount of damage (i.e., permeability impairment) and depth of penetration (from core inlet towards outlet) are particularly emphasized. Filter methods (e.g., using millipore filter) cannot be used to determine particle invasions into porous medium. Any predictions of the injection problems based on millipore (or any other filter) measurements are useless and should be discarded.

Much of the debate over U.S. policy toward Iran has centered on the nature of the current regime; some believe that Iran, a country of about 70 million people, is a threat to U.S. interests because hardliners in Iran's regime dominate and set a policy direction intended to challenge U.S. influence and allies in the region. President George W. Bush, in his January 29, 2002, State of the Union message, labeled Iran part of an "axis of evil" along with Iraq and North Korea. This report discusses the political history of Iran, U.S. strategy in Iran, and the Obama Administration's policies for dealing with Iran, especially with regard to the previous administration's policies.

This report discusses the current political state of Iran and its relationship with the United States. This report emphasizes in particular the Iranian presidential elections that took place on June 12, 2009; current U.S. efforts under President Obama to forge diplomatic talks with Iran while at the same time urging aggressive action in the way of certain economic and trade sanctions; and how current U.S. efforts under the Obama Administration differ and/or are similar to efforts under the Bush Administration.

The United Nations Convention on the Law of the Sea (LOS Convention) was agreed to in 1982, but the United States never became a signatory nation. In the 111th Congress, Secretary of State Hillary Clinton, at her confirmation hearing before the Senate Committee on Foreign Affairs on January 13, 2009, acknowledged that U.S. accession to the LOS Convention would be an Obama Administration priority. This report describes provisions of the LOS Convention relating to living marine resources and discusses how these provisions comport with current U.S. marine policy.

A letter report issued by the Government Accountability Office with an abstract that begins "In recent years GAO and others have reported on problems in the financial management environment at the Department of Homeland Security's (DHS) Science and Technology Directorate (S&T). S&T was established by the Homeland Security Act of 2002 to, among other things, coordinate the federal government's civilian efforts to identify and develop countermeasures to emerging terrorist threats to our nation. As DHS's primary research and development arm, the directorate is tasked with providing federal, state, local, and tribal officials with state-of-the-art technology and other resources, such as protocols and training procedures for use in responding to, and recovery from, chemical, biological, radiological, nuclear, and explosive attacks. S&T is led by an Under Secretary and has a Chief Financial Officer (CFO) who is responsible for all budgeting and accounting for financial resources. S&T receives funds for research, development, acquisition, and operations. It also receives funds for management and administration that support the operations of the directorate in both headquarters and the field, such as the expenditures for personnel compensation and benefits, travel, and rent. The Department of Homeland Security Appropriations Act, 2007 (Appropriations Act) provided about $973 million …

A letter report issued by the Government Accountability Office with an abstract that begins "There has been long-standing congressional interest in whether the Department of Defense (DOD) could use the Department of Veterans Affairs (VA) Consolidated Mail Outpatient Pharmacy (CMOP) system as a cost-effective alternative to beneficiaries picking up outpatient refill prescriptions at DOD military treatment facilities (MTF). To evaluate this possibility, DOD and VA conducted a pilot program in fiscal year 2003 in which a VA CMOP provided outpatient pharmaceutical refill services to DOD beneficiaries served through three MTFs. GAO was asked to estimate cost savings that could be achieved if DOD used VA's CMOP instead of MTF pharmacies for outpatient refill prescriptions, and what other benefits were achieved at the three pilot sites. To estimate potential cost savings and determine what other benefits were achieved, GAO reviewed pilot and pharmacy program documentation and interviewed DOD and VA officials responsible for purchasing and dispensing drugs. GAO also compared drug and administrative costs of dispensing outpatient refills through the fiscal year 2003 pilot program with the costs of dispensing the refills at the three DOD MTFs that participated in the pilot."

A letter report issued by the Government Accountability Office with an abstract that begins "The Army Working Capital Fund (AWCF) collected over $16 billion for goods and services provided to customers in fiscal year 2009. Cash generated from sales is used by AWCF to cover its expenses such as paying employees. In light of the Army's changing role in the Middle East, GAO was asked to determine whether (1) AWCF's monthly cash balances fell within the Department of Defense's (DOD) cash requirements for fiscal years 2000 through 2009, (2) the cash transfers resulted in AWCF's monthly cash balances falling below the minimum amount required by DOD, and (3) the AWCF's projected monthly cash balances are expected to fall below DOD's minimum cash requirement for fiscal years 2010 and 2011 and actions the Army can take to manage those balances. To address these objectives, GAO (1) reviewed relevant DOD guidance, (2) obtained and analyzed AWCF budget and accounting reports containing cash information, and (3) interviewed DOD and Army officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1940s, the development of nuclear weapons technologies has generated transuranic wastes--materials contaminated by certain man-made radioactive elements. These wastes can remain dangerous for thousands of years. Until 1970, the Department of Energy's (DOE) predecessors buried these wastes in shallow pits and trenches. Today, state officials and communities near DOE's major disposal sites have expressed concerns that such wastes might contaminate important ground and surface water resources. GAO was asked to (1) determine the legal requirements and policies affecting DOE's efforts to address transuranic wastes buried before 1970, (2) determine what DOE is doing to address sites where these transuranic wastes are buried, and (3) assess the reliability of DOE's estimated costs to address these sites. We met with federal and state officials at five DOE sites containing buried transuranic wastes, reviewed environmental laws and guidance, and obtained buried waste cleanup cost estimates from each site. In commenting on this report, DOE generally agreed with our findings, and provided some clarifying comments."

A letter report issued by the Government Accountability Office with an abstract that begins "Since fiscal year 2006, Congress has annually prohibited the use of federal funds to inspect horses destined for food, effectively prohibiting domestic slaughter. The U.S. Department of Agriculture (USDA) is responsible for overseeing the welfare of horses transported for slaughter. Congress directed GAO to examine horse welfare since cessation of domestic slaughter in 2007. GAO examined (1) the effect on the U.S. horse market, if any, since cessation; (2) any impact of these market changes on horse welfare and on states, local governments, tribes, and animal welfare organizations; and (3) challenges, if any, to USDA's oversight of the transport and welfare of U.S. horses exported for slaughter. GAO analyzed horse price and shipping data, and interviewed officials from USDA, state and local governments, tribes, the livestock industry, and animal welfare organizations, and reviewed documents they provided.."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) provides healthcare to millions of veterans at VA's medical centers and healthcare facilities across the country. To support veterans, VA manages a Federal Supply Schedule (FSS) program and a national contract program. Both use VA's sizeable buying power to provide VA and other federal agencies discounts on medical products and services. To cover its costs in running the FSS program, VA charges its customers a user fee. Although sales through VA's FSS and national contracts totaled almost $7 billion in fiscal year 2003, concerns have been raised about the efficiency of these contract programs. GAO was asked to determine whether the FSS and national contracts have provided medical products at favorable prices and to identify opportunities to improve purchasing practices and increase savings. GAO was also asked to determine if VA's user fee is sufficient to cover program cost."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government is the nation's largest energy consumer, spending, by latest accounting, $3.7 billion on energy for its 500,000 facilities. Upfront funding for energy-efficiency improvements has been difficult to obtain because of budget constraints and competing agency missions. The Congress in 1986 authorized agencies to use Energy Savings Performance Contracts (ESPCs) to privately finance these improvements. The law requires that annual payments for ESPCs not exceed the annual savings generated by the improvements. GAO was asked to identify (1) the extent to which agencies used ESPCs; (2) what energy savings, financial savings, and other benefits agencies expect to achieve; (3) the extent to which actual financial savings cover costs; and (4) what areas, if any, require steps to protect the government's financial interests in using ESPCs."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO estimates that under the 2010 Patient Protection and Affordable Care Act (PPACA), about three-quarters of approximately 7 million children who were uninsured in January 2009 would be eligible for Medicaid, the State Children’s Health Insurance Program (CHIP), or the new premium tax credit. The remaining children had family incomes too high to be eligible, were noncitizens, or would be ineligible for the premium tax credit because they would be considered to have access to affordable employer-sponsored insurance per the Internal Revenue Service’s (IRS) proposed affordability standard, in which IRS interpreted PPACA as defining affordability for an employee’s eligible family members based on the cost of an employee-only plan. Some commenters raised concerns that IRS’s interpretation was inconsistent with PPACA’s goal of increasing access to affordable health insurance as it does not consider the higher cost of family insurance and could result in some children remaining uninsured. Under PPACA, CHIP is not funded beyond 2015, and states may opt to reduce CHIP eligibility or eliminate programs in fiscal year 2020. Without CHIP, more children could become uninsured. In May 2012, IRS finalized its rule but deferred …

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past decade, per capita consumption of bottled water in the United States has more than doubled. With this increase have come several concerns in recent years about the safety, quality, and environmental impacts of bottled water. The Food and Drug Administration (FDA) regulates bottled water under the Federal Food, Drug, and Cosmetic Act as a food and is responsible for ensuring that domestic and imported bottled water is safe and truthfully labeled. Among other things, GAO (1) evaluated the extent to which FDA regulates and ensures the quality and safety of bottled water; (2) evaluated the extent to which federal and state authorities regulate the accuracy of labels and claims regarding the purity and source of bottled water; and (3) identified the environmental and other impacts of bottled water. GAO reviewed FDA data, reports, and requirements for bottled water; conducted a state survey of all 50 states and the District of Columbia; reviewed bottled water labels; and interviewed FDA officials and key experts."

A letter report issued by the Government Accountability Office with an abstract that begins "Annual pay adjustments for the General Schedule (GS), the pay system covering the majority of federal workers, are either determined through the process specified in the Federal Employees Pay Comparability Act of 1990 (FEPCA) or set based on percent increases authorized directly by Congress. GS employees receive an across-the-board increase (ranging from 0 to 3.8 percent since FEPCA was implemented) that has usually been made in accordance with a FEPCA formula linking increases to national private sector salary growth. This increase is the same for each employee. GS employees also receive a locality increase that varies based on their location; there were 34 pay localities in 2012. While FEPCA specifies a process designed to reduce federal-nonfederal pay gaps in each locality, in practice locality increases have usually been far less than the recommended amount, which has been over 15 percent in recent years. For 2012, when there was a freeze on annual pay adjustments, the FEPCA process had recommended a 1.1 percent across-the-board increase and an average 18.5 percent locality increase."

A letter report issued by the Government Accountability Office with an abstract that begins "The increasing threat of improvised explosive devices (IED) in Iraq has led to widespread interest by Congress and the public regarding the availability of critical force protection equipment. GAO initiated a series of engagements under the Comptroller General's authority to address these concerns. In March 2006, GAO reported on factors that affected the production and installation of armor for the Army's medium and heavy trucks. This engagement examines issues affecting the production and installation of armor for the Marine Corps' medium and heavy trucks. The objectives were to (1) determine the extent to which truck armor was produced and installed to meet identified requirements, (2) identify what factors affected the time to provide truck armor, and (3) identify what actions the Marine Corps and DOD have taken to improve the timely availability of truck armor."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has a large, diverse portfolio of property it uses to carry out its mission. GAO's objectives were to (1) describe DHS's real property portfolio; (2) determine what challenges, if any, DHS faces in managing real property and what actions it has taken in response to the administration's real property initiative; (3) determine what challenges DHS and the General Services Administration (GSA) face in consolidating DHS's Washington, D.C. headquarters; and (4) describe actions DHS has taken to help ensure the security of its facilities. GAO reviewed documents and interviewed officials from DHS, GSA, and other stakeholders, including the National Capital Planning Commission (NCPC) and the District of Columbia (D.C.)."

A letter report issued by the Government Accountability Office with an abstract that begins "Critical to the success of the federal government's transformation are its people--human capital. Yet, the government has not transformed, in many cases, how it classifies, compensates, develops, and motivates its employees to achieve maximum results within available resources and existing authorities. GAO has reported that the federal government as a whole may face challenges in offering competitive compensation to its senior leaders who have reached a statutory pay cap. As requested, GAO (1) provided trend data for basic pay rates of selected federal executive and judicial pay plans from 1970 to 2006, (2) identified elements of total compensation for the selected pay plans in 2006, and (3) identified principles for any possible restructuring of these pay plans. We selected 1970 as a baseline because salary increases went into effect in 1969 for executive-level positions as recommended by the Commission on Executive, Legislative, and Judicial Salaries. The pay plans cover the following--career Senior Executive Service (SES), administrative law judges (ALJ), senior-level (SL), Executive Schedule (EX), scientific or professional (ST), and members of Boards of Contract Appeals (BCA), as well as federal justices and judges--the Chief Justice, associate …

A letter report issued by the Government Accountability Office with an abstract that begins "The crime of sexual assault has serious consequences for both the aggrieved and the accused. The severity of these consequences underscores the importance of impartially administering justice in order to promote accountability and confidence that such allegations are taken seriously. GAO was asked to address the extent to which (1) the Department of Defense (DOD) conducts oversight of the military services' investigative organizations and (2) the services provide resources for investigations and adjudications of alleged sexual assault incidents. GAO also identified an issue relating to the military's criminal code during this review. GAO analyzed relevant DOD and service policies and procedures; reviewed applicable laws, including provisions of the Uniform Code of Military Justice; and interviewed senior DOD and service officials, including a total of 48 judge advocates and DOD civilian lawyers, at the headquarters level and at five selected military installations."

A letter report issued by the Government Accountability Office with an abstract that begins "Recognizing the humanitarian crisis in Darfur, Sudan, Congress enacted the Sudan Accountability and Divestment Act (SADA) in 2007. This law supports U.S. states' and investment companies' decisions to divest from companies with certain business ties to Sudan. It also seeks to prohibit federal contracting with these companies. GAO was asked to (1) identify actions that U.S. state fund managers and investment companies took regarding Sudan-related assets; (2) describe the factors that these entities considered in determining whether and how to divest; and (3) determine whether the U.S. government has contracted with companies identified as having certain Sudan-related business operations and assess compliance with SADA's federal contract prohibition provision. GAO surveyed states, analyzed data on investment companies and companies with Sudan-related business operations, assessed federal contracts, and reviewed documents and interviewed officials from the Securities and Exchange Commission (SEC), among other federal agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "While the Department of Health and Human Services (HHS) has established a framework for protecting the privacy and security of Medicare beneficiaries’ prescription drug use information when used for purposes other than direct clinical care through its issuance of regulations, outreach, and enforcement activities, it has not issued all required guidance or fully implemented required oversight capabilities. HHS has issued regulations including the Health Insurance Portability and Accountability Act (HIPAA) Privacy and Security Rules to safeguard protected health information from unauthorized use and disclosure. Through its Office for Civil Rights (OCR), HHS has undertaken a variety of outreach and educational efforts to inform members of the public and covered entities about the uses of protected health information. Specifically, OCR has made available on its website guidance and other materials informing the public about the uses to which their personal information may be put and the protections afforded to that information by federal laws. It has also made available guidance to covered entities and their business associates that is intended to promote compliance with the HIPAA Privacy and Security Rules."

A letter report issued by the Government Accountability Office with an abstract that begins "In its role as the nation's tax collector, the Internal Revenue Service (IRS) has a demanding responsibility to annually collect trillions of dollars in taxes, process hundreds of millions of tax and information returns, and enforce the nation's tax laws. Since its first audit of IRS's financial statements in fiscal year 1992, GAO has identified a number of weaknesses in IRS's financial management operations. In related reports, GAO has recommended corrective actions to address those weaknesses. Each year, as part of the annual audit of IRS's financial statements, GAO makes recommendations to address any new weaknesses identified and follows up on the status of IRS's efforts to address the weaknesses GAO identified in previous years' audits. The purpose of this report is to (1) provide an overview of the financial management challenges still facing IRS, (2) provide the status of financial audit and financial management-related recommendations and the actions needed to address them, and (3) highlight the relationship between GAO's recommendations and internal control activities central to IRS's mission and goals."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) does not maintain complete information on New Source Review (NSR) permits issued to fossil fuel electricity generating units. State and local permitting agencies track the NSR permits they issue, but EPA does not maintain complete or centralized information on permits, despite a 2006 recommendation by the National Research Council that it do so. EPA maintains several databases that compile data on draft and issued NSR permits, but these sources are incomplete and thus cannot be used to identify all of the NSR permits that have been issued nationwide. In addition, EPA has the opportunity to review and comment on every draft NSR permit issued by state and local permitting agencies, but it does not compile data on whether the permitting agencies address EPA’s comments in final permits. The absence of more complete information on NSR permitting makes it difficult to know which units have obtained NSR permits or to assess how state and local permitting agencies vary from EPA in their interpretations of NSR requirements."
