This report discusses issues for Congress in FY2011, which are whether to approve, reject, or modify DOD's new KC-X competition strategy, and whether to approve, reject, or modify the Air Force's request for FY2011 research and development funding for the new KC-X program.

We report a kinematically complete experiment on the production of CO{sup +} autoionizing states following photoionization of carbon monoxide below its vertical double ionization threshold. Momentum imaging spectroscopy is used to measure the energies and body-frame angular distributions of both photo- and autoionization electrons, as well as the kinetic energy release (KER) of the atomic ions. This data, in combination with ab initio theoretical calculations, provides insight into the nature of the cation states produced and their subsequent dissociation into autoionizing atomic (O*) fragments.

This report provides background information on the C-17 Aircraft program, including previous appropriations, related programs, and issues for Congress. The primary issue for Congress in FY2010 is whether to procure additional C-17s. An additional issue is whether to pass legislation relating to the airlift aircraft force structure. Congress's decisions on these issues could affect DOD capabilities and funding requirements and the U.S. military aircraft industrial base.

This report details the Obama Administration's proposed FY2010 defense budget requests for F-35 program funding and outlines the issues that Congress must consider when deciding whether to approve, reject, or modify the administration's funding requests.

The bacterial mercury resistance (mer) operon functions in Hg biogeochemistry and bioremediation by converting reactive inorganic [Hg(II)] and organic [RHg(I)] mercurials to relatively inert monoatomic mercury vapor, Hg(0). Its genes regulate expression (MerR, MerD, MerOP), import Hg(II) (MerT, MerP, and MerC), and demethylate (MerB) and reduce (MerA) mercurials. We focus on how these components interact with each other and with the host cell to allow cells to survive and detoxify Hg compounds. Understanding how this ubiquitous detoxification system fits into the biology and ecology of its bacterial host is essential to guide interventions that support and enhance Hg remediation. At a more basic level, studies of interactions between the metal ion trafficking proteins in this pathway provide insights into general mechanisms used by proteins in pathways involved in trafficking of other metal ions in cells of all types of organisms, including pathways for essential metal ions such as Cu and Zn and other toxic metal ions such as Cd. In this project we focused on investigations of proteins from mer operons found in gamma-proteobacteria with specific objectives to use biophysical and biochemical approaches to detect and define (1) interactions between the structural components of the key detoxifying mer operon enzyme, …

In December 2004, Google announced its Library Project, which was to entail digitizing, indexing, and displaying "snippets" of print books in the collections of five major libraries, among other things. The Library Project was not limited to books in the public domain (e.g., books whose terms of copyright protection had expired), and Google did not seek the permission of copyright holders, in part, because it asserted that its proposed uses were fair uses. Many authors, publishers, and other rights holders disagreed. This report provides background on the Library Project, legal issues raised by digitization and indexing projects, and the status of the litigation over the Library Project.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

I appreciate the opportunity to provide comments on the joint rulemaking to establish greenhouse gas emission and fuel economy standards for light-duty vehicles. My comments are directed at the choice of vehicle footprint as the attribute by which to vary fuel economy and greenhouse gas emission standards, in the interest of protecting vehicle occupants from death or serious injury. I have made several of these points before when commenting on previous NHTSA rulemakings regarding CAFE standards and safety. The comments today are mine alone, and do not necessarily represent the views of the US Department of Energy, Lawrence Berkeley National Laboratory, or the University of California. My comments can be summarized as follows: (1) My updated analysis of casualty risk finds that, after accounting for drivers and crash location, there is a wide range in casualty risk for vehicles with the same weight or footprint. This suggests that reducing vehicle weight or footprint will not necessarily result in increased fatalities or serious injuries. (2) Indeed, the recent safety record of crossover SUVs indicates that weight reduction in this class of vehicles resulted in a reduction in fatality risks. (3) Computer crash simulations can pinpoint the effect of specific design changes …

This report provides information about The Current Structure and Its Role in the Changing Telecommunications Landscape on the Federal Communications Commission. The FCC is an independent agency with its five members appointed by the president.

Testimony issued by the Government Accountability Office with an abstract that begins "Advancing technology has led to increasing sales of new electronic devices. With this increase comes the dilemma of managing them at the end of their useful lives. If discarded with common trash, a number of environmental impacts may result, ranging from the loss of valuable resources to the potential release of toxic substances, such as lead. If recycled, they may be exported to countries with waste management systems that are less protective of human health and the environment that those of the United States. The federal government is the world's largest purchaser of electronics, spending nearly $75 billion on electronic products and services in 2009. The Environmental Protection Agency (EPA) has helped implement several product stewardship initiatives to encourage responsible management of electronic products in all three phases of a product's lifecycle--procurement, operation, and end-of-life disposal. In response to a request to provide information on federal procurement and management of electronic products, GAO's testimony describes (1) EPA's electronic product stewardship initiatives, (2) federal agency participation in them, and (3) opportunities for strengthening participation. GAO's testimony is based on its prior work and updated with data from EPA. In …

Testimony issued by the Government Accountability Office with an abstract that begins "In August 2007, GAO reported (GAO-07-993) that Legal Services Corporation (LSC) had not kept up with evolving reforms aimed at strengthening governance, accountability and internal controls. In December 2007, GAO reported (GAO-08-37) weaknesses in LSC's internal controls over grants management and oversight of grantees. GAO was asked to testify on the status of accountability practices of the LSC. GAO's testimony is primarily a summary of our prior reporting, but includes follow up work conducted between May and October 2009 to obtain information on the status of our prior recommendations."

Correspondence issued by the Government Accountability Office with an abstract that begins "A fundamental principle of military readiness is that the military must train as it intends to fight. Military training ranges provide the primary means to accomplish this goal. The Department of Defense's (DOD) training ranges vary in size from a few acres, for small arms training, to over a million acres for large maneuver exercises and weapons testing, and include broad open ocean areas for offshore training and testing. New advances in military technology, coupled with the complexity of recent military operations in Iraq, Afghanistan, and other locations around the world, generate the need to continually update and maintain DOD's training ranges. Senior DOD and military service officials have reported for some time that they face increasing difficulties in carrying out realistic training at military installations due to outside influences. DOD has defined a number of factors--including competition for broadcast frequencies or airspace, air pollution, noise pollution, endangered species, critical habitats and other protected resources, unexploded ordinance and munitions, urban growth around installations, and civilian access--that it says encroach upon its training ranges and capabilities. Because the military faces obstacles in acquiring new training lands, the preservation and …

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 …

Testimony issued by the Government Accountability Office with an abstract that begins "Access to broadband service is seen as vital to economic, social, and educational development, yet many areas of the country lack access to, or their residents do not use, broadband. To expand broadband deployment and adoption, the American Recovery and Reinvestment Act (the Recovery Act) provided $7.2 billion to the Department of Commerce's National Telecommunications and Information Administration (NTIA) and the Department of Agriculture's Rural Utilities Service (RUS) for grants or loans to a variety of program applicants. The agencies must award all funds by September 30, 2010. This testimony provides preliminary information on the challenges NTIA and RUS face; the steps taken to address challenges; and the remaining risks in (1) evaluating applications and awarding funds and (2) overseeing funded projects. This statement is based on related ongoing work that GAO expects to complete in November. To conduct this work, GAO is reviewing relevant laws and program documents and interviewing agency officials and industry stakeholders. While this testimony does not include recommendations, GAO expects to make recommendations in its November report."

Concurrency levels in large-scale, distributed-memory supercomputers are rising exponentially. Modern machines may contain 100,000 or more microprocessor cores, and the largest of these, IBM's Blue Gene/L, contains over 200,000 cores. Future systems are expected to support millions of concurrent tasks. In this dissertation, we focus on efficient techniques for measuring and analyzing the performance of applications running on very large parallel machines. Tuning the performance of large-scale applications can be a subtle and time-consuming task because application developers must measure and interpret data from many independent processes. While the volume of the raw data scales linearly with the number of tasks in the running system, the number of tasks is growing exponentially, and data for even small systems quickly becomes unmanageable. Transporting performance data from so many processes over a network can perturb application performance and make measurements inaccurate, and storing such data would require a prohibitive amount of space. Moreover, even if it were stored, analyzing the data would be extremely time-consuming. In this dissertation, we present novel methods for reducing performance data volume. The first draws on multi-scale wavelet techniques from signal processing to compress systemwide, time-varying load-balance data. The second uses statistical sampling to select a small …

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).

This report discusses the current political climate in Tanzania, an important U.S. ally in Africa. The report also provides some general background information.

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Greg Abbott, regarding a legal question submitted for clarification; Whether Texas State Technical College (TSTC) can legally enter into a student loan program with a private lender, whereby TSTC and the private lender share the risk of students defaulting on the loans (RQ-0803-GA)

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 …

Short period (14.5mm) hybrid undulator arrays composed of Praseodymium Iron Boron (Pr{sub 2}Fe{sub 14}B) magnets (CR53, NEOMAX, Inc.) and vanadium permendur poles have been fabricated at Brookhaven National Laboratory. Unlike Neodymium Iron Boron (Nd{sub 2}Fe{sub 14}B) magnets which exhibit spin reorientation at temperatures below 150K, PrFeB arrays monotonically increase performance with lower operating temperature. It opens up the posibility for use in operating a cryo-permanent magnet undulator (CPMU) in the range of 40K to 60K where very efficient cryocoolers are available. Magnetic flux density profiles were measured at various temperature ranges from room temperature down to liquid helium (LHe) using the Vertical Testing Facility (VTF) at the National Snchrotron Light Source-II (NSLS-II). Temperature variations of phase error have been characterized. In addition, we examined the use of textured Dysprosium (Dy) poles to replace permendur poles to obtain further improvement in performance.
