A letter report issued by the General Accounting Office with an abstract that begins "Birdwatching, hunting, and wildlife photography provide important recreational, aesthetic, and income-generating benefits to the American public. In addition, wildlife help maintain ecosystems, and the mere knowledge that wildlife exist is viewed as beneficial by many people. At the same time, however, some wildlife destroy crops, kill livestock, damage property, and pose risks to public health and safety. Further, as the U.S. population has grown and impinged upon wildlife habitats, conflicts between wildlife and humans and their property have become increasingly common. Wildlife Services, a program within the U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service, is tasked with controlling damage by wildlife. Mammals and birds damage crops, forestry seedlings, and aquaculture products each year, at a cost of hundreds of millions of dollars. In fiscal year 2000, predators killed half a million livestock--mostly lambs and calves--valued at $70 million. To reduce such threats, Wildlife Services conducts operational and research activities with federal, state, and local agencies; agricultural producers and ranchers; private homeowners; and others. In carrying out these activities, Wildlife Services applies the most appropriate methods, whether lethal or nonlethal, of prevention and …

A letter report issued by the General Accounting Office with an abstract that begins "Congress authorized the Recreational Fee Demonstration Program to help federal land management agencies provide high-quality recreational opportunities to visitors and protect resources. The program focuses on recreational activities at the following four land management agencies: the National Park Service, the Fish and Wildlife Service, the Bureau of Land Management, and the Forest Service. Under the fee demonstration program, participating agencies can collect fees at several sites and use them to (1) enhance visitor services, (2) address a backlog of needs for repair and maintenance, and (3) manage and protect resources. The agencies applied "entrance fees" for basic admission to an area and "user fees" for specific activities such as camping or launching a boat. Under the law, 80 percent of program revenue must be used at the site where it was collected. The rest may be distributed to other sites that may or may not be participating in the demonstration program. Some of the sites GAO surveyed experimented with innovative fee designs and collection methods, such as reducing fees during off-peak seasons and allowing visitors to use credit cards, but room for additional innovation exists, particularly …

A letter report issued by the General Accounting Office with an abstract that begins "In April 2003, Congress enacted the Postal Civil Service Retirement System (CSRS) Funding Reform Act of 2003 (P.L. 108-18), which\ lowered the Postal Service's (Service) annual payment for its CSRS obligation by over $2.5 billion beginning in fiscal year 2003. P.L. 108-18 includes requiring (1) the Service to begin making payments into an escrow account in fiscal year 2006, (2) the Service to issue a report on its proposed use of "savings" resulting from the lower CSRS payments, and (3) GAO to evaluate the Service's report and present its findings to Congress. GAO evaluated whether the Service's proposals were consistent with P.L. 108-18; the impact of the escrow account; and whether the proposals were fair to current and future ratepayers, affordable, and helped achieve transformation goals."

A letter report issued by the General Accounting Office with an abstract that begins "Financial relationships between individual investigators or their research institutions and private industry have yielded significant results, including treatments for such diseases as AIDS and strokes. However, some collaborations have raised concerns that the focus on financial reward might compromise the integrity of the research and the safety of human research subjects. GAO reviewed five universities with broad policies and procedures on financial conflicts of interest. All five had difficulty providing basic data on individual investigators' financial conflicts of interest in clinical research involving human subjects. The universities acknowledged a need for better coordination of information on investigators' financial relationships, and several universities were developing ways to do so. Policies and procedures at the five universities addressed financial conflicts of interest affecting institutions, including technology transfer activities and financial relationships with small start-up companies that market products developed by the universities. The Department of Health and Human Services has had limited success in promoting the integrity of biomedical research and protecting human subjects. HHS has taken steps to improve its oversight and monitoring and has drafted guidance on financial conflicts of interest, but this guidance does not …

A letter report issued by the General Accounting Office with an abstract that begins "The Postal Civil Service Retirement System Funding Reform Act of 2003 (the Act) required the United States Postal Service, Department of the Treasury, and Office of Personnel Management (OPM) to prepare proposals detailing whether and to what extent the Treasury and Postal Service should fund the benefits attributable to the military service of the Postal Service's current and former Civil Service Retirement System (CSRS) employees. The Act required GAO to evaluate the proposals. Our objective in doing so was to assess the agencies' positions and provide additional information where it may be useful."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO provided information on the Access to Jobs and Reverse Commute program, which provides grants to improve transportation to employment for welfare recipients, focusing on the: (1) Department of Transportation's (DOT) implementation of the Job Access program, particularly its approach for selecting awards in fiscal year (FY) 1999; (2) FY 1999 grantees and their planned approaches for providing transportation services to low-income workers; and (3) changes DOT is making to the program in response to GAO's prior recommendations, including the establishment of specific objectives, performance criteria, and measurable goals for evaluating the program's success."

This report provides a brief overview of the European Union's (EU) accession process; Turkey's path to EU membership; the impact of the Cyprus problem; and a review of the United States' interest in Turkey's future in the European Union.

A letter report issued by the Government Accountability Office with an abstract that begins "While the President and the Office of Management and Budget (OMB) have established policies and procedures for coordinating investments in geospatial data, governmentwide committees and federal departments and agencies have not effectively implemented them. The committee that was established to promote the coordination of geospatial data nationwide--the Federal Geographic Data Committee (FGDC)--has developed and endorsed key standards-- including a metadata standard that includes descriptive information about a particular set of geospatial data--and established a clearinghouse of metadata; however, the clearinghouse is not being used by agencies to identify planned geospatial investments to promote coordination and reduce duplication. The FGDC has not yet planned or implemented an approach to manage geospatial data as related groups of investments to allow agencies to more effectively plan geospatial data collection efforts and minimize duplicative investments; and its strategic plan is missing key elements, such as performance measures for many of its defined objectives. Further, none of the three federal departments in GAO's review have fully implemented important activities for coordinating geospatial data, such as preparing and implementing a strategy for advancing geospatial activities within their respective departments."

This report provides a summary of seven proposed and final rules affecting the Medicaid program that were issued by the Bush Administration during 2007 and 2008. Six of the seven rules are currently under a congressional moratorium on further administrative action until April 1, 2009. A description of possible administrative and legislative actions to modify these rules, which could be taken by the next administration or the 111th Congress, is also provided.

This report provides background data on United States arms sales agreements with and deliveries to its major purchasers during calendar years 2000-2007. In a series of data tables, it lists the total dollar values of U.S. government-to-government arms sales agreements with its top five purchasers in five specific regions of the world for three specific periods: 200-2003, 2004-2007, and 2007 alone, and the total dollar values of U.S. arms deliveries to its top five purchasers in those same regions and time periods. The report also provides data tables listing the total dollar values of U.S. government-to-government arms agreements with and deliveries to its top 10 purchasers worldwide for those same time periods.

This report is an introductory and selective explanation of the rules, procedures, and practices by which the House of Representatives considers public bills and resolutions on the floor. After discussions of the nature of House rules, the differences between the House and the Committee of the Whole, and limitations on debate, the report describes five different ways in which the House may consider, perhaps debate and amend, and then vote on whether to pass legislation. The report also discusses the House's calendars and its order of business, the special rules reported by the Rules Committee, House consideration of Senate amendments and conference reports, and the rules and constitutional requirements affecting voting and quorum procedures.

The 1992 U.N. Framework Convention on Climate Change requires that signatories, including the United States, establish policies for constraining future emission levels of greenhouse gases, including carbon dioxide (CO2). The George H. W. Bush, Clinton, and George W. Bush Administrations each drafted action plans in response to requirements of the convention. These plans have raised significant controversy and debate. This report examines three starting points from which a U.S. response to the convention is being framed.

This paper describes the results of a year-long project, sponsored by the Energy Facility Contractors Group (EFCOG) and designed to improve overall electrical safety performance throughout Department of Energy (DOE)-owned sites and laboratories. As evidenced by focused metrics, the Project was successful primarily due to the joint commitment of contractor and DOE electrical safety experts, as well as significant support from DOE and contractor senior management. The effort was managed by an assigned project manager, using classical project-management principles that included execution of key deliverables and regular status reports to the Project sponsor. At the conclusion of the Project, the DOE not only realized measurable improvement in the safety of their workers, but also had access to valuable resources that will enable them to do the following: evaluate and improve electrical safety programs; analyze and trend electrical safety events; increase electrical safety awareness for both electrical and non-electrical workers; and participate in ongoing processes dedicated to continued improvement.

The goal of this project was to perform simulations of beam transport in linear colliders, with an emphasis on emittance dilution, spin polarization transport, and development and testing of beam based tuning algorithms. Our simulations are based on an existing object-oriented particle-tracking library, Bmad. To facilitate the efficient development of simulations, an accelerator design and analysis program based on Bmad has been developed called Tao (Tool for Accelerator Optics). The three beam-based alignment algorithms, Dispersion Free Steering, Ballistic Alignment (BA), and the Kubo Method have been implemented in Tao. We have studied the effects of magnet misalignments, BPM resolution, beam jitter, stray fields, BPM and steering magnet failure and the effects of various cavity shape wakefields. A parametric study has been conducted in the presence of the above types of errors for all three alignment algorithms. We find that BPM resolution has only modest impact on the effectiveness of beam based alignment. The DFS correction algorithm was found to be very robust in situations where there were BPM and/or steering magnet failures. The wakefields in the main linac are very weak and cause negligible emittance growth. Spin tracking was extended to study all accelerator components between the damping ring and …

Remote Systems Engineering (RSE) of the Savannah River National Lab (SRNL) in combination with the Defense Waste Processing Facility(DWPF) Engineering and Operations has evaluated the existing equipment and processes used in the facility sample cells for 'pulling' samples from the radioactive waste stream and performing equipment in-cell repairs/replacements. RSE has designed and tested equipment for improving remote in-cell sampling evolutions and reducing the time required for in-cell maintenance of existing equipment. The equipment within the present process tank sampling system has been in constant use since the facility start-up over 17 years ago. At present, the method for taking samples within the sample cells produces excessive maintenance and downtime due to frequent failures relative to the sampling station equipment and manipulator. Location and orientation of many sampling stations within the sample cells is not conducive to manipulator operation. The overextension of manipulators required to perform many in-cell operations is a major cause of manipulator failures. To improve sampling operations and reduce downtime due to equipment maintenance, a Portable Sampling Station (PSS), wireless in-cell cameras, and new commercially available sampling technology has been designed, developed and/or adapted and tested. The uniqueness of the design(s), the results of the scoping tests, and …

By harvesting waste heat from engine exhaust and storing it in light-weight high-capacity modules, it is believed that the need for energy transport by convoys can be lowered significantly. By storing this power during operation, substantial electrical power can be provided during long periods of silent operation, while the engines are not operating. It is proposed to investigate the potential of installing efficient thermoelectric generators on the exhaust systems of trucks and other vehicles to generate electrical power from the waste heat contained in the exhaust and to store that power in advanced power packs comprised of polymer-gel lithium ion batteries. Efficient inexpensive methods for production of the thermoelectric generator are also proposed. The technology that exists at LLNL, as well as that which exists at industrial partners, all have high technology readiness level (TRL). Work is needed for integration and deployment.

Tank 5 at the Savannah River Site has been used to store high level waste and is currently undergoing waste removal processes in preparation for tank closure. Samples were taken from two locations to determine the contents in support of Documented Safety Analysis (DSA) development for chemical cleaning. These samples were obtained through the use of the Drop Core Sampler and the Snowbank Sampler developed by the Engineered Equipment & Systems (EES) group of the Savannah River National Laboratory (SRNL).

In view of the looming energy crisis facing our planet, attention increasingly focuses on materials potentially useful as a basis for energy saving technologies. The discovery of giant magnetocaloric (GMC) compounds - materials that exhibit especially large changes in temperature as the externally applied magnetic field is varied - is one such compound 1. These materials have potential for use in solid state cooling technology as a viable alternative to existing gas based refrigeration technologies that use choro-fluoro - and hydro-fluoro-carbon chemicals known to have a severe detrimental effect on human health and environment 2,3. Examples of GMC compounds include Gd5(SiGe)4 4, MnFeP1-xAsx 5 and Ni-Mn-Ga shape memory alloy based compounds 6-8. Here we explain how the properties of one of these compounds (Ni2MnGa) can be tuned as a function of temperature by adding dopants. By altering the free energy such that the structural and magnetic transitions coincide, a GMC compound that operates at just the right temperature for human requirements can be obtained 9. We show how Cu, substituted for Mn, pulls the magnetic transition downwards in temperature and also, counterintuitively, increases the delocalization of the Mn magnetism. At the same time, this reinforces the Ni-Ga chemical bond, raising …

Releases from the F and H Area Seepage Basins on the Savannah River Site (SRS) have caused groundwater plumes that contain a variety of contaminants. These plumes are releasing contaminants into Fourmile Branch, which is a small tributary of the Savannah River. The metallic contaminant releases to the branch are being controlled by base injection. The base injection targets cationic contaminants and was not intended to reduce the concentration of I-129 in groundwater. SRS and the regulatory agencies believe it is appropriate to investigate remedial alternatives that could reduce the I-129. The Savannah River Site Area Closures Projects (ACP) and the Savannah River National Laboratory (SRNL) are developing an innovative in situ treatment for I-129 using silver chloride (AgCl). The proposed AgCl amendment has a very small particle size and is designed to be injected into the contaminated aquifer to capture I-129. The solubility of AgI is several orders of magnitude lower than the solubility of AgCl. Thus, when I-129 comes in contact with AgCl it forms silver iodide (AgI), which is very stable and essentially insoluble in water. SRNL has been performing bench-scale column tests on the effectiveness of silver chloride to capture iodine in an aqueous solution. These …

High-average-current linear electron accelerators require photoinjectors capable of delivering tens to hundreds of mA average current, with peak currents of hundreds of amps. Standard photocathodes face significant challenges in meeting these requirements, and often have short operational lifetimes in an accelerator environment. We report on recent progress toward development of secondary emission amplifiers for photocathodes, which are intended to increase the achievable average current while protecting the cathode from the accelerator. The amplifier is a thin diamond wafer which converts energetic (few keV) primary electrons into hundreds of electron-hole pairs via secondary electron emission. The electrons drift through the diamond under an external bias and are emitted into vacuum via a hydrogen-terminated surface with negative electron affinity (NEA). Secondary emission gain of over 200 has been achieved. Two methods of patterning diamond, laser ablation and reactive-ion etching (RIE), are being developed to produce the required geometry. A variety of diagnostic techniques, including FTIR, SEM and AFM, have been used to characterize the diamonds.

This document presents a detailed evaluation of selected alternative treatment options to granular activated carbon (GAC) for removing carbon tetrachloride generated from the groundwater pump-and-treat system at the 200-ZP-I Operable Unit (OU) in the 200 West Area of the Hanford Site. This evaluation of alternative treatment options to GAC is also applicable to the vadose zone soil vapor extraction (SVE) system at the 200-PW-l OU, which is also located in the Hanford Site's 200 West Area.

We investigate aerosol effects on climate for 1980, 1995 (meant to reflect present-day) and 2030 using the NASA Goddard Institute for Space Studies climate model coupled to an on-line aerosol source and transport model with interactive oxidant and aerosol chemistry. Aerosols simulated include sulfates, organic matter (OM), black carbon (BC), sea-salt and dust and additionally, the amount of tropospheric ozone is calculated, allowing us to estimate both changes to air quality and climate for different time periods and emission amounts. We include both the direct aerosol effect and indirect aerosol effects for liquid-phase clouds. Future changes for the 2030 A1B scenario are examined, focusing on the Arctic and Asia, since changes are pronounced in these regions. Our results for the different time periods include both emission changes and physical climate changes. We find that the aerosol indirect effect (AIE) has a large impact on photochemical processing, decreasing ozone amount and ozone forcing, especially for the future (2030-1995). Ozone forcings increase from 0 to 0.12 Wm{sup -2} and the total aerosol forcing increases from -0.10 Wm{sup -2} to -0.94 Wm{sup -2} (AIE increases from -0.13 to -0.68 Wm{sup -2}) for 1995-1980 versus 2030-1995. Over the Arctic we find that compared to …

This paper describes ongoing advancement of airborne hazard modeling capabilities in support of multiple agencies through the National Atmospheric Release Advisory Center (NARAC) and the Interagency Atmospheric Modeling and Atmospheric Assessment Center (IMAAC). A suite of software tools developed by Lawrence Livermore National Laboratory (LLNL) and collaborating organizations includes simple stand-alone, local-scale plume modeling tools for end user's computers, Web- and Internet-based software to access advanced 3-D flow and atmospheric dispersion modeling tools and expert analysis from the national center at LLNL, and state-of-the-science high-resolution urban models and event reconstruction capabilities.

This report describes earthquake activity within approximately 65 km of Yucca Mountain site during the October 1, 2004 to September 30, 2006 time period (FY05-06). The FY05-06 earthquake activity will be compared with the historical and more recent period of seismic activity in the Yucca Mountain region. The relationship between the distribution of seismicity and active faults, historical patterns of activity, and rates of earthquakes (number of events and their magnitudes) are important components in the assessment of the seismic hazard for the Yucca Mountain site. Since October 1992 the University of Nevada has compiled a catalog of earthquakes in the Yucca Mountain area. Seismicity reports have identified notable earthquake activity, provided interpretations of the seismotectonics of the region, and documented changes in the character of earthquake activity based on nearly 30 years of site-characterization monitoring. Data from stations in the seismic network in the vicinity of Yucca Mountain is collected and managed at the Nevada Seismological Laboratory (NSL) at the University of Nevada Reno (UNR). Earthquake events are systematically identified and cataloged under Implementing Procedures developed in compliance with the Nevada System of Higher Education (NSHE) Quality Assurance Program. The earthquake catalog for FY05-06 in the Yucca Mountain region …
