This report outlines the key provisions of the Consumer Assistance to Recycle and Save (CARS) program established by P.L. 111-32, which provide rebates to prospective purchasers toward the purchase of new, fuel-efficient vehicles, provided the trade-in vehicles are scrapped. It discusses the impact of the program on the economy and also summarizes similar programs in other industrial countries.

The United States provides assistance to 47 African countries, and the United States Agency for International Development (USAID) has 23 missions in Africa. In recent years, U.S. assistance to Africa saw a major increase, especially in health-related programs. This report provides an overview of U.S. aid to Africa, including the strategic objectives that shape U.S. aid to Africa, information about specific aid programs and initiatives, and the Obama Administration's FY2011 foreign aid budget request.

This report discusses several programs offered by the U.S. Department of Agriculture (USDA) to help farmers recover financially from natural disasters, including drought and floods. All the programs have permanent authorization, and only one requires a federal disaster designation (the emergency loan program). Most programs receive funding amounts that are "such sums as necessary" and are not subject to annual discretionary appropriations.

This report discusses the United States Border Patrol's history as our nation's first line of defense against unauthorized migration. Today, the USBP's primary mission is to detect and prevent the entry of terrorists, weapons of mass destruction, and illegal aliens into the country, and to interdict drug smugglers and other criminals along the border.

Integrated energy, environment and economics modeling suggests electrical energy use will increase from 2.4 TWe today to 12 TWe in 2100. It will be challenging to provide 40% of this electrical power from combustion with carbon sequestration, as it will be challenging to provide 30% from renewable energy sources. Thus nuclear power may be needed to provide ~30% by 2100. Calculations of the associated stocks and flows of uranium, plutonium and minor actinides indicate that the proliferation risks at mid-century, using current light-water reactor technology, are daunting. There are institutional arrangements that may be able to provide an acceptable level of risk mitigation, but they will be difficult to implement. If a transition is begun to fast-spectrum reactors at mid-century, without a dramatic change in the proliferation risks of such systems, at the end of the century proliferation risks are much greater, and more resistant to mitigation. The risks of nuclear power should be compared with the risks of the estimated 0.64oC long-term global surface-average temperature rise predicted if nuclear power were replaced with coal-fired power plants without carbon sequestration. Fusion energy, if developed, would provide a source of nuclear power with much lower proliferation risks than fission.

Since the 1970's, federal incentives have played a major role in encouraging agriculture-based renewable energy production. Policy goals include the stimulation of alternative uses of domestic grain and oilseeds, the promotion of national security through greater energy independence, and the encouragement of rural economic development.

For the first time, a detailed chemical kinetic reaction mechanism is developed for primary reference fuel mixtures of n-hexadecane and 2,2,4,4,6,8,8-heptamethyl nonane for diesel cetane ratings. The mechanisms are constructed using existing rules for reaction pathways and rate expressions developed previously for the primary reference fuels for gasoline octane ratings, n-heptane and iso-octane. These reaction mechanisms are validated by comparisons between computed and experimental results for shock tube ignition and for oxidation under jet-stirred reactor conditions. The combined kinetic reaction mechanism contains the submechanisms for the primary reference fuels for diesel cetane ratings and submechanisms for the primary reference fuels for gasoline octane ratings, all in one integrated large kinetic reaction mechanism. Representative applications of this mechanism to two test problems are presented, one describing fuel/air autoignition variations with changes in fuel cetane numbers, and the other describing fuel combustion in a jet-stirred reactor environment with the fuel varying from pure 2,2,4,4,6,8,8-heptamethyl nonane (Cetane number of 15) to pure n-hexadecane (Cetane number of 100). The final reaction mechanism for the primary reference fuels for diesel fuel and gasoline is available on the web.

The regulations in 10 CFR 71 require that the radioactive material (RAM) packages must be able to withstand specific fire conditions given in 10 CFR 71.73 during Hypothetical Accident Conditions (HAC). This requirement is normally satisfied by extensive testing of full scale test specimens under required test conditions. Since fire test planning and execution is expensive and only provides a single snapshot into a package performance, every effort is made to minimize testing and supplement tests with results from computational thermal models. However, the accuracy of such thermal models depends heavily on the thermal properties of the fire insulating materials that are rarely available at the regulatory fire temperatures. To the best of authors knowledge no test standards exist that could be used to test the insulating materials and derive their thermal properties for the RAM package design. This paper presents a review of the existing industry fire testing standards and proposes testing methods that could serve as a standardized specification for testing fire insulating materials for use in RAM packages.

This report discusses: The National Earthquake Hazards Reduction Program NEHRP; earthquake hazards and risk in the United States; federal programs that support earthquake monitoring; the U.S. capability to detect earthquakes and issue notifications and warnings; and federally supported research to improve the fundamental scientific understanding of earthquakes with a goal of reducing U.S. vulnerability.

A strong argument can be made that there is a greater need to study the effect of warming on boreal forests more than on any other terrestrial biome. Boreal forests, the second largest forest biome, are predicted to experience the greatest warming of any forest biome in the world, but a process-based understanding of how warming will affect the structure and function of this economically and ecologically important forest biome is lacking. The effects of warming on species composition, canopy structure and biogeochemical cycles are likely to be complex; elucidating the underlying mechanisms will require long-term whole-ecosystem manipulation to capture all the complex feedbacks (Shaver et al. 2000, Rustad et al. 2001, Stromgren 2001). The DOE Program for Ecosystem Research funded a three year project (2002-2005) to use replicated heated chambers on soil warming plots in northern Manitoba to examine the direct effects of whole-ecosystem warming. We are nearing completion of our first growing season of measurements (fall 2004). In spite of the unforeseen difficulty of installing the heating cable, our heating and irrigation systems worked extremely well, maintaining environmental conditions within 5-10% of the specified design 99% of the time. Preliminary data from these systems, all designed and built …

Flow dynamics in large wind projects are influenced by the turbines located within. The turbine wakes, regions characterized by lower wind speeds and higher levels of turbulence than the surrounding free stream flow, can extend several rotor diameters downstream, and may meander and widen with increasing distance from the turbine. Turbine wakes can also reduce the power generated by downstream turbines and accelerate fatigue and damage to turbine components. An improved understanding of wake formation and transport within wind parks is essential for maximizing power output and increasing turbine lifespan. Moreover, the influence of wakes from large wind projects on neighboring wind farms, agricultural activities, and local climate are all areas of concern that can likewise be addressed by wake modeling. This work describes the formulation and application of an actuator disk model for studying flow dynamics of both individual turbines and arrays of turbines within wind projects. The actuator disk model is implemented in the Weather Research and Forecasting (WRF) model, which is an open-source atmospheric simulation code applicable to a wide range of scales, from mesoscale to large-eddy simulation. Preliminary results demonstrate the applicability of the actuator disk model within WRF to a moderately high-resolution large-eddy simulation study …

Testimony issued by the Government Accountability Office with an abstract that begins "Medicare Part D, the voluntary, outpatient prescription drug benefit for eligible individuals 65 years and older and certain individuals with disabilities, is at risk for fraud, waste, and abuse. Part D is administered by the Centers for Medicare & Medicaid Services (CMS). All Part D sponsors--private companies that operate Part D benefit plans--are required to have programs to safeguard the Part D program from fraud, waste, and abuse. GAO refers to these programs as fraud and abuse programs. This statement discusses CMS's oversight of Part D sponsors' fraud and abuse programs, including its past efforts and planned oversight activities. It is primarily based on the GAO report, Medicare Part D: Some Plan Sponsors Have Not Completely Implemented Fraud and Abuse Programs, and CMS Oversight Has Been Limited (GAO-08-760). The five Part D sponsors GAO reviewed for that report had not completely implemented all of CMS's elements for Part D fraud and abuse programs at that time. CMS agreed with GAO's recommendation in the report that it conduct timely audits of Part D sponsors' fraud and abuse programs. For the 2008 report, GAO reviewed laws, regulation, and CMS documents, …

The Merged Sounding value-added product (VAP) uses a combination of observations from radiosonde soundings, the microwave radiometer (MWR), surface meteorological instruments, and European Centre for Medium-Range Weather Forecasts (ECMWF) model output with a sophisticated scaling/interpolation/smoothing scheme in order to define profiles of the atmospheric thermodynamic state at one-minute temporal intervals and a total of 266 altitude levels.

Testimony issued by the Government Accountability Office with an abstract that begins "The September 11, 2001, terrorist attacks raised concerns about the security of Department of Energy (DOE) sites with weapons-grade nuclear material, known as Category I special nuclear material (SNM). To better protect these sites against attacks, DOE has sought to transform its protective forces protecting SNM into a Tactical Response Force (TRF) with training and capabilities similar to the U.S. military. This testimony is based on prior work and has been updated with additional information provided by protective forces' union officials. In a prior GAO report, Nuclear Security: DOE Needs to Address Protective Forces' Personnel System Issues (GAO-10-275), GAO (1) analyzed information on the management, organization, staffing, training, and compensation of protective forces at DOE sites with Category I SNM; (2) examined the implementation of TRF; and (3) assessed DOE's two options to more uniformly manage protective forces; and (4) reported on DOE's progress in addressing protective force issues. DOE generally agreed with the recommendations in GAO's prior report that called for the agency to fully assess and implement, where feasible, measures identified by DOE's 2009 protective forces study group to enhance protective forces' career longevity and retirement …

Understanding the response of energetic material to thermal event is very important for the storage and handling of energetic materials. The One Dimensional Time to Explosion (ODTX) system at the Lawrence Livermore National Laboratory (LLNL) can precisely measure times to explosion and minimum ignition temperatures of energetic materials at elevated temperatures. These measurements provide insight into the relative ease of thermal ignition and allow for the determination of kinetic parameters. The ODTX system can potentialy be a good tool to measure violence of the thermal ignition by monitoring the size of anvil cavity. Recent ODTX experimental data on various energetic materials (solid and liquids) are reported in this paper.

Considerable effort has been dedicated to determining the possible properties of a magneticconfinement fusion power plant, particularly in the U.S.1, Europe2 and Japan3. There has also been some effort to detail the development path to fusion energy, particularly in the U.S.4 Only limited attention has been given, in Japan5 and in China6, to the options for a specific device to form the bridge from the International Thermonuclear Experimental Reactor, ITER, to commercial fusion energy. Nor has much attention been paid, since 2003, to the synergies between magnetic and inertial fusion energy development. Here we consider, at a very high level, the possibility of a Qeng ≥ 1 Pilot Plant, with linear dimensions ~ 2/3 the linear dimensions of a commercial fusion power plant, as the needed bridge. As we examine the R&D needs for such a system we find significant synergies between the needs for the development of magnetic and inertial fusion energy.

This report examines poverty in the United States. In 2008, 39.8 million people were counted as poor in the United States - an increase of 2.6 million persons from 2007, and nearly the largest number of persons counted as poor since 1960. The poverty rate, or percent of the population considered poor under the official definition, was reported at 13.2%; this is up from 12.5% in 2007, and is the highest rate since 1997. The recent increase in poverty reflects the worsening of economic conditions since the onset of the economic recession in December 2007. Many expect poverty to rise further next year, and it will likely remain comparatively high even after the economy begins to recover. The incidence of poverty varies widely across the population according to age, education, labor force attachment, family living arrangements, and area of residence, among other factors.

A letter report issued by the Government Accountability Office with an abstract that begins "This report responds to two ongoing GAO mandates under the American Recovery and Reinvestment Act of 2009 (Recovery Act). It is the fifth in a series of reports since passage of the Recovery Act on the uses of and accountability for Recovery Act funds in 16 selected states, certain localities in those jurisdictions, and the District of Columbia (District). These jurisdictions are estimated to receive about two-thirds of the intergovernmental assistance available through the Recovery Act. It is also the second report in which GAO is required to comment on the jobs created or retained as reported by recipients of Recovery Act funds. GAO collected and analyzed documents and interviewed state and local officials and other Recovery Act award recipients. GAO also analyzed federal agency guidance and spoke with officials at federal agencies overseeing Recovery Act programs."
