Testimony issued by the Government Accountability Office with an abstract that begins "Conflicts of interest typically exist when someone in a position of trust, such as a pension consultant, has competing professional or personal issues. Such competing interests can make it difficult for pension plan fiduciaries and others, in general, to fulfill their duties impartially and could cause them to breach their duty to act solely in the interest of plan participants and beneficiaries. The proliferation of consulting work and the complexity of business arrangements among investment advisors, plan consultants, and others have increased the likelihood of conflicts of interests for both defined benefit (DB) plans, where investment risk is largely borne by the plan sponsor and defined contribution (DC) plans, where such risk is largely borne by the participant. Given the potential financial harm conflicts of interest may pose to DB and DC plans, GAO was asked to report on (1) the effects undisclosed conflicts of interest may have on the financial performance of DB plans, and (2) the vulnerabilities that conflicts of interest may pose for DC plan participants. GAO interviewed a variety of experts, reviewed the Department of Labor's (Labor) legal and regulatory authority and analyzed government …

Testimony issued by the Government Accountability Office with an abstract that begins "For years, the Social Security Administration (SSA) has experienced challenges managing a large disability workload and making timely decisions. In fiscal year 2006, SSA made about 3.7 million disability claims decisions, while over a million were awaiting a decision. Further, SSA has faced staffing challenges and difficulties managing its workloads at its network of approximately 1,300 field offices, where millions of people go to apply for disability and retirement benefits, to obtain Social Security cards, and for a host of other services. The Subcommittees on Income Security and Family Support, and on Social Security, House Committee on Ways and Means, asked GAO to address (1) key service delivery challenges facing SSA, particularly with respect to the backlog of disability claims, and (2) steps SSA is taking to address these challenges. This testimony is based primarily on reports assessing trends in disability claims processing and backlogs, steps SSA is taking to reduce the backlog, and other challenges SSA faces in meeting future service delivery needs. Certain information was updated to reflect recent legislative changes."

Testimony issued by the Government Accountability Office with an abstract that begins "GAO has a large body of work examining government agencies' approaches to managing their large acquisition projects. GAO has noted that without sufficient knowledge about system requirements, technology, and design maturity, programs are subject to cost overruns, schedule delays, and performance that does not meet expectations. The Deepwater Program, intended to replace or modernize 15 major classes of Coast Guard assets, accounts for almost 60 percent of the Coast Guard's fiscal year 2009 appropriation for acquisition, construction and improvements. GAO has reported over the years on this program, which has experienced serious performance and management problems such as cost breaches, schedule slips, and assets designed and delivered with significant defects. To carry out the Deepwater acquisition, the Coast Guard contracted with Integrated Coast Guard Systems (ICGS) as a systems integrator. In April 2007, the Commandant acknowledged that the Coast Guard had relied too heavily on contractors to do the work of government and announced that the Coast Guard was taking over the lead role in systems integration from ICGS. This testimony reflects our most recent issued work on Deepwater, specifically our June 2008 report, Coast Guard: Change in …

Other written product issued by the Government Accountability Office with an abstract that begins "To assist the 111th Congress, this report presents a series of issue papers for consideration in developing congressional oversight agendas and determining the way forward in securing and stabilizing Iraq. These papers are based on the continuing work of the U.S. Government Accountability Office (GAO) and the more than 130 Iraq-related products we have issued since May 2003. Since fiscal year 2001, Congress has provided about $808 billion to the Department of Defense (DOD) for military efforts primarily in support of the Global War on Terrorism. The majority of this amount has been for military operations in support of Operation Iraqi Freedom. Moreover, since fiscal year 2003, about $49 billion has been provided to U.S. agencies for stabilization and reconstruction efforts in Iraq, including developing Iraq's security forces, enhancing Iraq's capacity to govern, and rebuilding Iraq's oil, electricity, and water sectors, among other activities. This report expands on issues discussed on GAO's transition Web site. In January 2007, President Bush announced The New Way Forward in Iraq to stem violence and enable the Iraqi government to foster national reconciliation. To support the strategy, the United States …

A new spatially resolving x-ray crystal spectrometer capable of measuring continuous spatial profiles of high resolution spectra (λ/dλ > 6000) of He-like and H-like Ar Kα lines with good spatial (~1 cm) and temporal (~10 ms) resolutions has been installed on the Alcator C-Mod tokamak. Two spherically bent crystals image the spectra onto four two-dimensional Pilatus II pixel detectors. Tomographic inversion enables inference of local line emissivity, ion temperature (Ti), and toroidal plasma rotation velocity (vφ) from the line Doppler widths and shifts. The data analysis techniqu

The Savannah River Site's (SRS) H-Canyon facility uses ceric ammonium nitrate (CAN) to separate impure neptunium (Np) from a high sulfate feed stream. The material is processed using a two-pass solvent extraction purification which relies on CAN to oxidize neptunium to Np(VI) during the first pass prior to extraction. Spectrophotometric oxidation-state analyses normally used to validate successful oxidation to Np(VI) prior to extraction were compromised by this feed stream matrix. Therefore, a rapid chromatographic method to validate successful Np oxidation was developed using Eichrom Industries TRU and TEVA{reg_sign} resins. The method was validated and subsequently transferred to existing operations in the process analytical laboratories.

Cadmium Zinc Telluride (CdZnTe or CZT) is a very attractive material for using as room-temperature semiconductor detectors, because it has a wide bandgap and a high atomic number. However, due to the material's poor hole mobility, several special techniques were developed to ensure its suitability for radiation detection. Among them, the virtual Frisch-grid CZT detector is an attractive option, having a simple configuration, yet delivering an outstanding spectral performance. The goal of our group in Brookhaven National Laboratory (BNL) is to improve the performance of Frisch-ring CZT detectors; most recently, that effort focused on the non-contacting Frisch-ring detector, allowing us to build an inexpensive, large-volume detector array with high energy-resolution and a large effective area. In this paper, the principles of virtual Frisch-grid detectors are described, especially BNL's innovative improvements. The potential applications of virtual Frisch-grid detectors are discussed, and as an example, a hand-held gamma-ray spectrometer using a CZT virtual Frischgrid detector array is introduced, which is a self-contained device with a radiation detector, readout circuit, communication circuit, and high-voltage supply. It has good energy resolution of 1.4% (FWHM of 662-keV peak) with a total detection volume of {approx}20 cm{sup 3}. Such a portable inexpensive device can be used …

A new facility for microdiffraction strain measurements and microfluorescence mapping has been built on beamline 12.3.2 at the advanced light source of the Lawrence Berkeley National Laboratory. This beamline benefits from the hard x-radiation generated by a 6 T superconducting bending magnet (superbend) This provides a hard x-ray spectrum from 5 to 22 keV and a flux within a 1 mu m spot of ~;;5x109 photons/ s (0.1percent bandwidth at 8 keV). The radiation is relayed from the superbend source to a focus in the experimental hutch by a toroidal mirror. The focus spot is tailored bytwo pairs of adjustable slits, which serve as secondary source point. Inside the lead hutch, a pair of Kirkpatrick-Baez (KB) mirrors placed in a vacuum tank refocuses the secondary slit source onto the sample position. A new KB-bending mechanism with active temperature stabilization allows for more reproducible and stable mirror bending and thus mirror focusing. Focus spots around 1 um are routinely achieved and allow a variety of experiments, which have in common the need of spatial resolution. The effective spatial resolution (~;;0.2 mu m) is limited by a convolution of beam size, scan-stage resolution, and stage stability. A four-bounce monochromator consisting of two …

Measurements of the defect levels and performance testing of CdZnTe detectors were performed by means of Current Deep Level Transient Spectroscopy (I-DLTS), Transient Charge Technique (TCT), Current versus Voltage measurements (I-V), and gamma-ray spectroscopy. CdZnTe crystals were acquired from different commercial vendors and characterized for their point defects. I-DLTS studies included measurements of defect parameters such as energy levels in the band gap, carrier capture cross sections, and defect densities. The induced current due to laser-generated carriers was measured using TCT. The data were used to determine the transport properties of the detectors under study. A good correlation was found between the point defects in the detectors and their performance.

Nanoscale ferrimagnetic particles have a diverse range of uses from directed cancer therapy and drug delivery systems to magnetic recording media and transducers. Such applications require the production of monodisperse nanoparticles with well-controlled size, composition, and magnetic properties. To fabricate these materials purely using synthetic methods is costly in both environmental and economical terms. However, metal-reducing microorganisms offer an untapped resource to produce these materials. Here, the Fe(III)-reducing bacterium Geobacter sulfurreducens is used to synthesize magnetic iron oxide nanoparticles. A combination of electron microscopy, soft X-ray spectroscopy, and magnetometry techniques was employed to show that this method of biosynthesis results in high yields of crystalline nanoparticles with a narrow size distribution and magnetic properties equal to the best chemically synthesized materials. In particular, it is demonstrated here that cobalt ferrite (CoFe{sub 2}O{sub 4}) nanoparticles with low temperature coercivity approaching 8 kOe and an effective anisotropy constant of {approx} 10{sup 6} erg cm{sup -3} can be manufactured through this biotechnological route. The dramatic enhancement in the magnetic properties of the nanoparticles by the introduction of high quantities of Co into the spinel structure represents a significant advance over previous biomineralization studies in this area using magnetotactic bacteria. The successful production of …

The original approach to nuclear reactor design or safety analyses was to make very conservative modeling assumptions so as to ensure meeting the required safety margins. Traditional regulation, as established by the U. S. Nuclear Regulatory Commission required conservatisms which have subsequently been shown to be excessive. The commission has therefore moved away from excessively conservative evaluations and has determined best-estimate calculations to be an acceptable alternative to conservative models, provided the best-estimate results are accompanied by an uncertainty evaluation which can demonstrate that, when a set of analysis cases which statistically account for uncertainties of all types are generated, there is a 95% probability that at least 95% of the cases meet the safety margins. To date, nearly all published work addressing uncertainty evaluations of nuclear power plant calculations has focused on light water reactors and on large-break loss-of-coolant accident (LBLOCA) analyses. However, there is nothing in the uncertainty evaluation methodologies that is limited to a specific type of reactor or to specific types of plant scenarios. These same methodologies can be equally well applied to analyses for high-temperature gas-cooled reactors and to liquid metal reactors, and they can be applied to steady-state calculations, operational transients, or severe accident …
