Coast Guard: Actions Needed to Mitigate Deepwater Project Risks
Testimony issued by the General Accounting Office with an abstract that begins "The Coast Guard is in the final stages of planning the largest procurement project in its history--the Deepwater Capability Replacement Project. This project will likely cost over $10 billion or more and take 20 years or more to complete. The Coast Guard has already spent about $116 million on the project's design and is asking for $338 million this year to begin the acquisition phase. This testimony discusses the major risks associated with the project. GAO found four major areas in which the project is vulnerable. They are (1) planning the project around annual funding levels far above what the administration has told the Coast Guard it can expect to receive, (2) keeping costs under control in the contract's later years, (3) ensuring that procedures and personnel are in place for managing and overseeing the contractor once the contract is awarded, and (4) minimizing potential problems with developing unproven technology. GAO also identified the following key areas that will need to be addressed. The Coast Guard needs (1) effective human capital practices, (2) a systems integrator to establish a management organization and systems necessary to manage the major …

Tax Compliance: Challenges in Ensuring Offshore Tax Compliance
Testimony issued by the Government Accountability Office with an abstract that begins "Offshore tax evasion is difficult for the Internal Revenue Service (IRS) to address. IRS examines tax returns to deal with offshore evasion that has occurred. IRS's Qualified Intermediary (QI) program seeks to foster improved tax withholding and reporting. GAO was asked to testify on two topics. First, GAO was asked to provide information on (1) the length of, and assessments from, IRS's examination of tax returns with offshore activity and (2) the impact of the 3-year statute of limitations on offshore cases. Second, for the QI program, GAO was asked to address (1) program features intended to improve withholding and reporting, and (2) whether weaknesses exist in the U.S. withholding system for U.S. source income and QI external reviews and IRS's use of program data. GAO relied on prior work for the first topic. For the QI program, GAO used the latest data that were available and corroborated by IRS."

Côte d'Ivoire Post-Gbagbo: Crisis Recovery
Côte d'Ivoire is emerging from a severe political-military crisis that followed a disputed November 28, 2010, presidential runoff election between former president Laurent Gbagbo and his, former Prime Minister Alassane Ouattara. Both claimed electoral victory and formed opposing governments. Their rivalry spurred a full-scale civil military conflict in early March 2011, after months of growing political violence. Armed conflict largely ended days after Gbagbo's arrest by pro-Ouattara forces, aided by United Nations (U.N.) and French peacekeepers, but limited residual fighting was continuing to occur as of April 20.

Proposed U.S.-Colombia Free Trade Agreement: Background and Issues
The United States is Colombia's leading trade partner. Colombia accounts for a very small percentage of U.S. trade (0.9% in 2010), ranking 20th among U.S. export markets and 25th as a source of U.S. imports. Economic studies on the impact of a U.S.-Colombia free trade agreement (FTA) have found that, upon full implementation of an agreement, the impact on the United States would be positive but very small due to the small size of the Colombian economy when compared to that of the United States (about 1.9%).

Clean Energy Standard: Potential Qualifying Energy Sources
This report begins with a brief examination of clean energy, renewable energy, and alternative energy. It then presents possible selection criteria Congress could use to determine which sources could be eligible for a CES depending on the goal(s) of the CES. The report provides an overview of the energy sources most commonly discussed as potential CES qualifying sources: biomass, fossil fuels (natural gas combined-cycle and coal-fired power plants with carbon capture and sequestration), geothermal resources, nuclear, solar, water, and wind. The report describes where each source can be found in the United States, the estimated quantity available for electricity generation, technologies used to create electricity from the source, advantages and disadvantages of using the source for electricity generation, and policy implications should the source be included in a CES.5 The report also contains a section on energy efficiency and its potential inclusion in a CES.

The Construction Sector in the U.S. Economy
The construction sector is a major component of the U.S. economy. During the past decade, construction was a prime beneficiary of low interest rates and the housing-led economic boom, but was also one of the largest casualties of the subsequent financial crisis. Construction spending comprised about 7%-8% of U.S. annual economic output from 1995 to mid-2000, reaching nearly 9% of gross domestic product at the peak of the housing run-up in 2006, before declining to about 5% in 2010. Likewise, construction employment ranged from a low of about 4.6 million during the early 1990s to a high of 7.7 million during the 2006 housing boom, and was about 5.5 million in early 2011.

Plan for Using Solar-Powered Jack Pumps to Sample Groundwater at the Nevada Test Site
Groundwater is sampled from 39 monitoring wells on the Nevada Test Site (NTS) as part of the Routine Radiological Environmental Monitoring Program. Many of these wells were not designed or constructed for long-term groundwater monitoring. Some have extensive completion zones and others have obstructions such as pumps and tubing. The high-volume submersible pumps in some wells are unsuitable for long-term monitoring and result in large volumes of water that may have to be contained and characterized before subsequent disposition. The configuration of most wells requires sampling stagnant well water with a wireline bailer. Although bailer sampling allows for the collection of depth-discrete samples, the collected samples may not be representative of local groundwater because no well purging is done. Low-maintenance, solar-powered jack pumps will be deployed in nine of these onsite monitoring wells to improve sample quality. These pumps provide the lift capacity to produce groundwater from the deep aquifers encountered in the arid environment of the NTS. The water depths in these wells range from 700 to 2,340 ft below ground surface. The considerable labor and electrical power requirements of electric submersible pumps are eliminated once these pumps are installed. Access tubing will be installed concurrent with the installation …

Assessing the Performance of 5mm White LED Light Sources forDeveloping-Country Applications
Some white light-emitting diode (LED) light sources haverecently attained levels of efficiency and cost that allow them tocompete with fluorescent lighting for off-grid applications in thedeveloping world. Additional attributes (optics, size, ruggedness, andservice life) make them potentially superior products. Enormousreductions in energy use and greenhouse-gas emissions are thus possible,and system costs can be much lower given the ability to downsize thecharging and energy storage components compared to a fluorescentstrategy. However, there is a high risk of "market-spoiling" if inferiorproducts are introduced and result in user dissatisfaction. Completesystems involve the integration of light sources and optics, energysupply, and energy storage. A natural starting point for evaluatingproduct quality is to focus on the individual light sources. This reportdescribes testing results for batches of 10 5mm white LEDs from 26manufacturers. Efficacies and color properties are presented.

Tomographic wavefront correction for the LSST
The Large Synoptic Survey Telescope (LSST) is a three mirror modified Paul-Baker design with an 8.4m primary, a 3.4m secondary, and a 5.0m tertiary followed by a 3-element refractive corrector producing a 3.5 degree field of view. This design produces image diameters of <0.3 arcsecond 80% encircled energy over its full field of view. The image quality of this design is sufficient to ensure that the final images produced by the telescope will be limited by the atmospheric seeing at an excellent astronomical site. In order to maintain this image quality, the deformations and rigid body motions of the three large mirrors must be actively controlled to minimize optical aberrations. By measuring the optical wavefront produced by the telescope at multiple points in the field, mirror deformations and rigid body motions that produce a good optical wavefront across the entire field may be determined. We will describe the details of the techniques for obtaining these solutions. We will show that, for the expected mirror deformations and rigid body misalignments, the solutions that are found using these techniques produce an image quality over the field that is close to optimal. We will discuss how many wavefront sensors are needed and the …

Future Accelerator Challenges in Support of High-Energy Physics
Historically, progress in high-energy physics has largely been determined by development of more capable particle accelerators. This trend continues today with the imminent commissioning of the Large Hadron Collider at CERN, and the worldwide development effort toward the International Linear Collider. Looking ahead, there are two scientific areas ripe for further exploration--the energy frontier and the precision frontier. To explore the energy frontier, two approaches toward multi-TeV beams are being studied, an electron-positron linear collider based on a novel two-beam powering system (CLIC), and a Muon Collider. Work on the precision frontier involves accelerators with very high intensity, including a Super-BFactory and a muon-based Neutrino Factory. Without question, one of the most promising approaches is the development of muon-beam accelerators. Such machines have very high scientific potential, and would substantially advance the state-of-the-art in accelerator design. The challenges of the new generation of accelerators, and how these can be accommodated in the accelerator design, are described. To reap their scientific benefits, all of these frontier accelerators will require sophisticated instrumentation to characterize the beam and control it with unprecedented precision.

ESTIMATING THE STRENGTH OF SINGLE-ENDED DISLOCATION SOURCES IN MICROMETER-SIZED SINGLE CRYSTALS
A recent study indicated that the behavior of single-ended dislocation sources contributes to the flow strength of micrometer-scale crystals. In this study 3D discrete dislocation dynamics simulations of micrometer-sized volumes are used to calculate the effects of anisotropy of dislocation line tension (increasing Poisson's ratio, {nu}) on the strength of single-ended dislocation sources and, to compare them with the strength of double-ended sources of equal length. This is done by directly modeling their plastic response within a 1 micron cubed FCC Ni single crystal using DDS. In general, double-ended sources are stronger than single-ended sources of an equal length and exhibit no significant effects from truncating the long-range elastic fields at this scale. The double-ended source strength increases with Poisson ratio ({nu}), exhibiting an increase of about 50% at u = 0.38 (value for Ni) as compared to the value at {nu} = 0. Independent of dislocation line direction, for {nu} greater than 0.20, the strengths of single-ended sources depend upon the sense of the stress applied. The value for {alpha}, in the expression for strength, {tau} = {alpha}(L){micro}b/L is shown to vary from 0.4 to 0.84 depending upon the character of the dislocation and the direction of operation of …

Gated Microchannel Plate Photomultiplier For Longitudinal BeamDiagnostics
A gated microchannel plate photomultiplier can be used as aneffective tool for measuring the longitudinal distribution of particlesaround most electron and high-energy proton rings. The broad availablewavelength range,low noise, and high sensitivity allow using such adevice for measuring the emitted synchrotron radiation and to extract thebeam intensity. The fast gate rise time can be used to reject strongsignals coming from filled RF buckets and avoid saturation of thephotocathode so that it is possible to monitor, with a high degree ofresolution, gaps in the machine fill and growth of parasitic bunches. Therugged characteristics of the device and its simplicity of use make itideal for all those applications where more complex and expensiveinstrumentation is not absolutely necessary. We present the experimentalresults obtained at the Advanced Light Source and on the Tevatron usingan Hamamatsu R5916U-50 series model.

Temporal changes in noble gas compositions within the Aidlinsector ofThe Geysers geothermal system
The use of nonreactive isotopic tracers coupled to a full thermal-hydrological reservoir simulation allows for an improved method of investigating how reservoir fluids contained within matrix and fractures contribute over time to fluids produced from geothermal systems. A combined field and modeling study has been initiated to evaluate the effects of injection, production, and fracture-matrix interaction on produced noble gas contents and isotopic ratios. Gas samples collected periodically from the Aidlin steam field at The Geysers, California, between 1997 and 2006 have been analyzed for their noble gas compositions, and reveal systematic shifts in abundance and isotopic ratios over time. Because of the low concentrations of helium dissolved in the injection waters, the injectate itself has little impact on the helium isotopic composition of the reservoir fluids over time. However, the injection process may lead to fracturing of reservoir rocks and an increase in diffusion-controlled variations in noble gas compositions, related to gases derived from fluids within the rock matrix.
