This report briefly describes recent geophysical and geotechnical instrumentation developments relevant to the studies of deep geologic repositories. Special emphasis has been placed on techniques that appear to minimize measurement problems associated with repositories constructed in basalt or domed salt. Included in the listing are existing measurement capabilities and deficiencies that have been identified by a few authors and instrumentation workshops that have assessed the capabilities of existing instrumentation with respect to repository applications. These deficiencies have been compared with the reported advantages and limitations of the new developments described. Based on these comparisons, areas that merit further research and development have been identified. The report is based on a thorough literature review and on discussions with several instrumentation specialists involved in instrumentation development.

This research strives to assess the impact of changing land use, nitrate deposition and CO{sub 2} fertilization on soil carbon storage. Our motivation is that this reservoir is the most likely candidate for the so-called missing carbon sink. We are working on several aspects of this problem by measuring carbon content, nitrogen content and radiocarbon ratios in paired soil samples from neighboring sites, to determine the impact of land use on soil carbon inventories and turnover times. We are also gathering information on how the C/N ratios in soils vary with climate and changing land use, in an effort to estimate how much carbon has been sequestered as a result of atmospheric fallout of NH{sub 4}OH and HNO{sub 3}. Finally, we are developing a soil greening model that uses CO{sub 2} growth-enhancement results and bomb radiocarbon-based estimates of soil carbon inventory response times.

A letter report issued by the General Accounting Office with an abstract that begins "Each year, millions of visitors, foreign students, and immigrants come to the United States. Foreign visitors may enter on a legal temporary basis--that is, with an authorized period of admission that expires on a specific date--either (1) with temporary visas (generally for tourism, business, or work) or, in some cases, (2) as tourists or business visitors who are allowed to enter without visas. (The latter include Canadians and qualified visitors from 27 countries who enter under the visa waiver program.) The majority of visitors who are tracked depart on time, but others overstay--and since September 11, 2001, the question has arisen as to whether overstay issues might have an impact on domestic security. In this report, we (1) describe available data on the extent of overstaying, (2) report on weaknesses in the Department of Homeland Security's long-standing overstay tracking system, and (3) provide some observations on the impact that tracking system weaknesses and significant levels of overstaying may have on domestic security."

A letter report issued by the Government Accountability Office with an abstract that begins "Although the Consumer Product Safety Commission (CPSC) enforces compliance with mandatory federal safety standards, it is also required by law to rely on voluntary safety standards when it determines that the standard adequately addresses the product hazard and is likely to have substantial compliance. Voluntary standards—developed by industry, consumer, and government participants through a consensus process—cover many of the thousands of types of products in CPSC’s jurisdiction. Compliance with voluntary standards is not routinely tracked, but it is generally considered to be high by industry participants. Compliance with these standards also depends on industry and legal factors, such as retailer requirements to demonstrate proof of compliance with voluntary safety standards and risk of liability in product liability lawsuits."

A letter report issued by the General Accounting Office with an abstract that begins "About 7 million undocumented aliens lived in the United States in 2000, according to Immigration and Naturalization Service estimates. Hospitals in states where many of them live report that treating them can be a financial burden. GAO was asked to examine the relationship between treating undocumented aliens and hospitals' costs not paid by patients or insurance. GAO was also asked to examine federal funding available to help hospitals offset costs of treating undocumented aliens and the responsibility of the Department of Homeland Security (Homeland Security) for covering medical expenses of sick or injured aliens encountered by Border Patrol and U.S. port-of-entry officials. To conduct this work, GAO surveyed 503 hospitals and interviewed Medicaid and hospital officials in 10 states. GAO also interviewed and obtained data from Homeland Security officials."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Homeland Security (DHS) faces the daunting task of bringing together 22 diverse agencies to lead efforts to protect the homeland. Among the challenges posed by this transformation is integrating these agencies' diverse information technology (IT) systems: mission support, administration, and infrastructure (e.g., networks). GAO was asked to determine (1) whether DHS has defined its IT systems integration strategy and (2) how DHS is ensuring that IT investments made by component agencies (specifically focusing on the Federal Emergency Management Agency, the Transportation Security Administration, and the Coast Guard) are aligned with the department's strategic direction."

A letter report issued by the Government Accountability Office with an abstract that begins "Established in 1998, the Job Access and Reverse Commute Program (JARC)-administered by the Federal Transit Administration (FTA)--awards grants to states and localities to provide transportation to help low-income individuals access jobs. In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act--A Legacy for Users (SAFETEA-LU) reauthorized the program and made changes, such as allocating funds by formula to large and small urban and rural areas through designated recipients, usually transit agencies and states. SAFETEA-LU also required GAO to periodically review the program. This second report under the mandate examines (1) the extent to which FTA has awarded JARC funds for fiscal years 2006 through 2008, and how recipients are using the funds; (2) challenges faced by recipients in implementing the program; and (3) FTA's plans to evaluate the program. For this work, GAO analyzed data and interviewed officials from FTA, nine states, and selected localities."

A letter report issued by the Government Accountability Office with an abstract that begins "Department of Defense (DOD) officials who serve in senior and acquisition positions and then leave for jobs with defense contractors are subject to the restrictions of post-government employment laws, in order to protect against conflicts of interest. Congress required GAO to report on employment of such officials by contractors who received more than $500 million in DOD's 2005 contract awards. In response, this report (1) provides information on how many former DOD employees worked for contractors in 2006 and estimates how many worked on contracts that were related to their former agencies or to their direct responsibilities and (2) identifies the practices used to monitor restrictions and information challenges in monitoring post-DOD employment. To do this work, GAO matched data from DOD for all employees who left DOD over a 6 year period with data from the Internal Revenue Service (IRS) and from 52 contractors; conducted surveys; and interviewed DOD and contractor officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The western United States, including vast stretches of federal land, is home to more than a third of the 1,317 species listed under the Endangered Species Act. Under section 7 of the act, federal agencies must ensure that any actions they authorize, fund, or carry out, whether on federal or private lands, do not jeopardize listed species. To fulfill this responsibility, the agencies often must formally consult with the Department of the Interior's U.S. Fish and Wildlife Service (Service), which issues a biological opinion assessing whether an action is likely to "take," or harm, a listed species. The Service may require the agencies to monitor and report on the action's effects on listed species, including take. For listed species subject to formal consultations in 11 western states, GAO was asked to examine the extent to which the Service tracks (1) required monitoring reports and (2) cumulative take. GAO reviewed the act, regulations, and policy and interviewed Service staff in all western states, reviewed 128 consultation files in five offices, and analyzed 23 listed species in detail."

A letter report issued by the Government Accountability Office with an abstract that begins "According to Census data, more than 12 million adults in the United States report they do not speak English well or at all. Proficiency in reading, writing, speaking, and understanding the English language appears to be linked to multiple dimensions of adult life in the United States, including financial literacy--the ability to make informed judgments and take effective actions regarding the current and future use and management of money. The Credit Card Accountability, Responsibility and Disclosure Act of 2009 mandated GAO to examine the relationship between fluency in the English language and financial literacy. Responding to this mandate, this report examines the extent, if any, to which individuals with limited English proficiency are impeded in their financial literacy and conduct of financial affairs. To address this objective, GAO conducted a literature review of relevant studies, reports, and surveys, and conducted interviews at federal, nonprofit, and private entities that address financial literacy issues and serve people with limited English proficiency. GAO also conducted a series of focus groups with consumers and with staff at community and financial organizations. GAO makes no recommendations in this report."

A letter report issued by the Government Accountability Office with an abstract that begins "Securing the control systems that regulate the nation's critical infrastructures is vital to ensuring our economic security and public health and safety. The Tennessee Valley Authority (TVA), a federal corporation and the nation's largest public power company, generates and distributes power in an area of about 80,000 square miles in the southeastern United States. GAO was asked to determine whether TVA has implemented appropriate information security practices to protect its control systems. To do this, GAO examined the security practices in place at several TVA facilities; analyzed the agency's information security policies, plans, and procedures against federal law and guidance; and interviewed agency officials who are responsible for overseeing TVA's control systems and their security."

A letter report issued by the General Accounting Office with an abstract that begins "In the 1990 and 2000 Censuses, U.S. military and federal civilian employees overseas were included in the numbers used for apportioning Congress. Currently, the U.S. Census Bureau (Bureau) is assessing the practicality of counting all Americans abroad by holding a test census in France, Kuwait, and Mexico. GAO was asked to (1) assess the soundness of the test design, and (2) examine what past court decisions have held about Americans' rights and obligations abroad."

A letter report issued by the General Accounting Office with an abstract that begins "Changes in the character and the conduct of warfighting and in the range and the nature of missions call for an Army force that is more responsive and dominant across the full spectrum of operations and requires much less in-theater logistics support. To meet these new demands, the Army is using the latest technology to develop a series of weapon systems that will be lighter than today's heavy force systems but just as lethal and survivable. The Army's transformation effort will face several challenges. First, the transformation will place additional funding demands on the defense budget. Second, the Army's plans for the transformation assume that weapons systems and equipment can be developed and acquired much faster than in the past. Third, the Army needs to update current acquisition plans to reflect transformation priorities and schedules. The success of this effort depends on the Army's ability to manage transformation acquisitions as leading commercial firms do. By following best practices used in the commercial sector, the Army can better match its needs with its resources."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the creation of 10 National Guard Rapid Assessment and Initial Detection (RAID) teams, focusing on: (1) obtaining the views of federal, state, and local officials regarding the role of RAID teams in response plans; (2) determining whether there are other federal, state, or local government entities that can perform similar functions to the RAID teams; and (3) evaluating the RAID teams' roles and responsibilities and how the teams plan to meet these responsibilities."

A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the Department of Defense's (DOD) efforts to incorporate common subsystems and components in its ballistic missile defense acquisition programs, focusing on: (1) the key benefits that the Ballistic Missile Defense Organization (BMDO) and service officials believe could be achieved through commonality; (2) what BMDO and the services have done to incorporate commonality into their programs; and (3) BMDO's plans for instilling commonality in the future."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO identified actions the Department of Agriculture (USDA) is taking to develop year 2000 business continuity and contingency plans (BCCP)."

A letter report issued by the General Accounting Office with an abstract that begins "The incremental costs for overseas military contingency operations, which include the enforcement of no-fly zones, humanitarian assistance, and peace enforcement, totaled more than $29 billion since 1991. Most of these costs were incurred in the Balkans and Southwest Asia. The Department of Defense (DOD) defines incremental costs as those above and beyond baseline training, operations, and personnel costs. Although most contingency operations expenditures GAO reviewed were appropriate, as much as $101 million was spent on questionable items, including cappuccino machines, golf memberships, and decorator furniture. Limited guidance and oversight, combined with a lack of cost consciousness, contributed to the questionable expenditures."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on whether changing Department of Veterans Affairs (VA) health care personnel licensing requirements would effect VA's health care system, focusing on: (1) comparing VA's physician employment requirements and processes with those of other federal agencies; (2) comparing VA's requirements with those of private sector health care organizations; (3) the potential benefits and costs of requiring VA physicians and registered nurses to be licensed in the state where they practice; and (4) the implications of such a licensing change on VA's use of telemedicine."

The reactions of OH radicals with hydrocarbons have received a great deal of attention in recent years because of these processes are principal steps in the oxidation of organic fuels -- whether occurring in combustion/propulsion systems, in the atmosphere, or elsewhere. Of the various radicals capable of attacking hydrocarbons, OH radicals are generally the most reactive, and their reactions directly yield water molecules, one of the major final oxidation products. In the atmosphere, the combined effect of the OH radical's reactivity and concentration make it the single species that determines the atmospheric lifetime of an organic substance. The principal goals of the kineticist in the field of oxidation chemistry are (1) to measure as many elementary reaction rate coefficients as are conveniently studied in the laboratory; and (2) to develop theoretical and/or semiempirical tools for extrapolating from measured rate coefficients to unmeasured ones. The latter step is necessary because of the sheer number of reactions of possible interest.
