A letter report issued by the Government Accountability Office with an abstract that begins "The E-Government Act (E-Gov Act) of 2002 was enacted with the general purpose of promoting better use of the Internet and other information technologies to improve government services for citizens, internal government operations, and opportunities for citizen participation in government. Among other things, the act specifically requires the establishment of the Office of Electronic Government within the Office of Management and Budget (OMB) to oversee implementation of the act's provisions and mandates a number of specific actions, such as the establishment of interagency committees, completion of several studies, submission of reports with recommendations, issuance of a variety of guidance documents, establishment of new policies, and initiation of pilot projects. Further, the act requires federal agencies to take a number of actions, such as conducting privacy impact assessments, providing public access to agency information, and allowing for electronic access to rulemaking proceedings. OMB has linked several of the act's provisions to ongoing e-government initiatives that it has sponsored. While some deadlines specified in the act have passed, many required actions do not have statutory deadlines or have deadlines that have not yet passed. This report responds to …

A letter report issued by the Government Accountability Office with an abstract that begins "As part of a multilayered effort to strengthen port security, the Maritime Transportation Security Act (MTSA) of 2002 calls for the Department of Homeland Security (DHS) to issue a worker identification card that uses biological metrics, such as fingerprints, to control access to secure areas of ports or ships. Charged with the responsibility for developing this card, the Transportation Security Administration (TSA), within DHS, initially planned to issue a Transportation Worker Identification Credential in August 2004 to about 6 million maritime workers. GAO assessed what factors limited TSA's ability to meet its August 2004 target date for issuing cards and what challenges remain for TSA to implement the card."

A letter report issued by the Government Accountability Office with an abstract that begins "FCC has regulatory authority over many complex telecommunications issues. To obtain expert advice on these issues, FCC often calls upon its federal advisory committees, comprised mostly of members from industry, private consulting, advocacy groups, and government. These committees must follow the Federal Advisory Committee Act (FACA), which sets requirements on the formation and operation of such committees. Because of Congressional interest in how FCC receives advice from outside experts, this report provides information on (1) FCC's current advisory committees, (2) the extent to which the committees follow applicable laws, (3) how FCC makes use of the committees' advice, and (4) the non-FACA advisory groups that FCC has established."

Correspondence issued by the Government Accountability Office with an abstract that begins "In 2003, we added the federal government's disability programs to our high-risk list in part because of difficulties agencies faced in managing these programs and the expected growth in the rolls as baby boomers reach their disability-prone years. The Social Security Administration (SSA) manages the federal government's two largest disability programs, the Disability Insurance (DI) program and the Supplemental Security Income (SSI) program, which together paid out $91 billion in federal benefits to 11.4 million individuals with disabilities in 2003. To help address management difficulties and prepare for expected growth in the rolls, SSA must have reliable administrative data from its disability decision-making process to adequately understand the population it serves and the possible effect of proposed program changes on this population. However, in a prior study, we identified potential problems with the reliability of SSA's electronic administrative data. This report examines (1) the extent to which SSA collects useful and reliable electronic administrative data in order to effectively manage its DI and SSI programs and (2) whether ongoing and planned changes to SSA's computer systems and internal controls will address any weaknesses that we identified."

A letter report issued by the Government Accountability Office with an abstract that begins "The school choice provision of the No Child Left Behind Act (NCLBA) of 2001 applies to schools that receive Title I funds and that have not met state performance goals for 2 consecutive years, including goals set before the enactment of NCLBA. Students in such schools must be offered the choice to transfer to another school in the district. GAO undertook this review to provide the Congress a report on the first 2 years of the implementation of NCLBA school choice. GAO reviewed (1) the number of Title I schools and students that have been affected nationally, (2) the experiences of selected school districts in implementing choice, and (3) the guidance and technical assistance that Education provided. GAO collected school performance data from all states, interviewed Education officials, and visited 8 school districts in California, Illinois, Ohio, Mississippi, Pennsylvania, Tennessee, and Washington."

With the advent of high energy density (HED) experimental facilities, such as high-energy lasers and fast Z-pinch, pulsed-power facilities, mm-scale quantities of matter can be placed in extreme states of density, temperature, and/or velocity. This has enabled the emergence of a new class of experimental science, HED laboratory astrophysics, wherein the properties of matter and the processes that occur under extreme astrophysical conditions can be examined in the laboratory. Areas particularly suitable to this class of experimental astrophysics include the study of opacities relevant to stellar interiors; equations of state relevant to planetary interiors; strong shock driven nonlinear hydrodynamics and radiative dynamics, relevant to supernova explosions and subsequent evolution; protostellar jets and high Mach-number flows; radiatively driven molecular clouds and nonlinear photoevaporation front dynamics; and photoionized plasmas relevant to accretion disks around compact objects, such as black holes and neutron stars.

Although healthy dentin is invariably hydrated in vivo, from a perspective of examining the mechanisms of fracture in dentin, it is interesting to consider the role of water hydration. Furthermore, it is feasible that exposure to certain polar solvents, e.g., those found in clinical adhesives, can induce dehydration. In the present study, in vitro deformation and fracture experiments, the latter involving a resistance-curve (R-curve) approach (i.e., toughness evolution with crack extension), were conducted in order to assess changes in the constitutive and fracture behavior induced by three common solvents - acetone, ethanol and methanol. In addition, nanoindentation-based experiments to evaluate the deformation behavior at the level of individual collagen fibers and ultraviolet Raman spectroscopy to evaluate changes in bonding were performed. The results indicate a reversible effect of chemical dehydration, with increased fracture resistance, strength, and stiffness associated with lower hydrogen bonding ability of the solvent. These results are analyzed both in terms of intrinsic and extrinsic toughening phenomena to further understand the micromechanisms of fracture in dentin and the specific role of water hydration.

Since the summer of 2003, a large Micromegas TPC prototype (1000 channels, 50 cm drift, 50 cm diameter) has been operated in a 2T superconducting magnet at Saclay. A description of this apparatus and first results from cosmic ray tests are presented. Additional measurements using simpler detectors with a laser source, an X-ray gun and radio-active sources are discussed. Drift velocity and gain measurements, electron attachment and aging studies for a Micromegas TPC are presented. In particular, using simulations and measurements, it is shown that an $Argon-CF_4$ mixture is optimal for operation at a future Linear Collider.

Oil and gas have been commercially produced in Illinois for over 100 years. Existing commercial production is from more than fifty-two named pay horizons in Paleozoic rocks ranging in age from Middle Ordovician to Pennsylvanian. Over 3.2 billion barrels of oil have been produced. Recent calculations indicate that remaining mobile resources in the Illinois Basin may be on the order of several billion barrels. Thus, large quantities of oil, potentially recoverable using current technology, remain in Illinois oil fields despite a century of development. Many opportunities for increased production may have been missed due to complex development histories, multiple stacked pays, and commingled production which makes thorough exploitation of pays and the application of secondary or improved/enhanced recovery strategies difficult. Access to data, and the techniques required to evaluate and manage large amounts of diverse data are major barriers to increased production of critical reserves in the Illinois Basin. These constraints are being alleviated by the development of a database access system using a Geographic Information System (GIS) approach for evaluation and identification of underdeveloped pays. The Illinois State Geological Survey has developed a methodology that is being used by industry to identify underdeveloped areas (UDAs) in and around petroleum …

This proposal had three major goals: (1) develop capillary electrophoresis mass spectrometry as a characterization technique, (2) separate a non-pertechnetate fraction from a waste sample and identify the non-pertechnetate species in it by CEMS, and (3) synthesize and characterize bulk quantities of the identified non-pertechnetate species and study their ligand substitution and redox chemistry.

Through the current EMSP funding, solvent extraction technologies based on liquid-liquid partitioning of TRU to an Ionic Liquid phase containing conventional complexants has been shown to be viable. The growing understanding of the role that the different components of an ionic liquid can have on the partitioning mechanism, and on the nature of the subsequent dissolved species indicates strongly that ionic liquids are not necessarily direct replacements for volatile or otherwise hazardous organic solvents. Separations and partitioning can be exceptionally complex with competing solvent extraction, cation, anion and sacrificial ion exchange mechanisms are all important, depending on the selection of components for formation of the ionic liquid phase, and that control of these competing mechanisms can be utilized to provide new, alternative separations schemes.

Much of the earth's pollution involves compounds of the metallic elements, including actinides, strontium, cesium, technetium, and RCRA metals. Metal ions bind to molecules called ligands, which are the molecular tools that can manipulate the metal ions under most conditions. This DOE-EMSP sponsored program strives (1) to provide the foundations for using the most powerful ligands in transformational separations technologies and (2) to produce seminal examples of their applications to separations appropriate to the DOE EM mission. These ultra tight-binding ligands can capture metal ions in the most competitive of circumstances (from mineralized sites, lesser ligands, and even extremely dilute solutions), but they react so slowly that they are useless in traditional separations methodologies. Two attacks on this problem are underway. The first accommodates to the challenging molecular lethargy by developing a seminal slow separations methodology termed the soil poultice. The second designs ligands that are only tight-binding while wrapped around the targeted metal ion, but can be put in place by switch-binding and removed by switch-release. We envision a kind of molecular switching process to accelerate the union between metal ion and tight-binding ligand. Molecular switching processes are suggested for overcoming the slow natural equilibration rate with which ultra …

Point-wise libraries provided with the MCNP code contain neutron data for a limited number of temperatures. However, it is important to have the option of using data from a wide range of temperatures for transport calculations. For this purpose, a multi-temperature, ACE-format neutron library was generated for 134 nuclides, as requested by Yucca Mountain Project (YMP) staff. The library is referred to as YUMMY (YUcca Mountain MCNP-librarY). The neutron cross section data are based on ENDF/B-V or ENDF/B-VI evaluations that were requested by YMP staff. This document provides the details of the new library and its use in criticality safety benchmark problems, a Pressurized Water Reactor design and waste package models in MCNP4C.

Dense nonaqueous phase liquid (DNAPL) contamination in the vadose zone is a significant problem at Department of Energy sites. Soil vapor extraction (SVE) is commonly used to remediate DNAPLs from the vadose zone. In most cases, a period of high recovery has been followed by a sustained period of low recovery. This behavior has been attributed to multiple processes including slow interphase mass transfer, retarded vapor phase transport, and diffusion from unswept zones of low permeability. This research project used a combination of laboratory experimentation and mathematical modeling to determine how these various processes interact to limit the removal of DNAPL components in heterogeneous porous media during SVE. Our results were applied to scenarios typical of the carbon tetrachloride spill zone at the Hanford Site. Our results indicate that: (a) the initial distribution of the spilled DNAPL (i.e., the spill-zone architecture) has a major influence upon the performance of any subsequent SVE operations; (b) while the pattern of higher and lower conductivity soil zones has an important impact upon spill zone architecture, soil moisture distribution plays an even larger role when there are large quantities of co-disposed waste-water (as in the Hanford scenario); (c) depending upon soil moisture dynamics, liquid …

Time-resolved FT-IR spectra of ethylene hydrogenation over alumina-supported Pt catalyst were recorded at 25 ms resolution in the temperature range 323 to 473 K using various H2 flow rates (1 atm total gas pressure). Surface ethyl species (2870 and 1200 cm-1) were detected at all temperatures along with the gas phase ethane product (2954 and 2893 cm-1). The CH3CH2Pt growth was instantaneous on the time scale of 25ms under all experimental conditions. At 323 K, the decay time of surface ethyl (122 + 10 ms) coincides with the rise time of C2H6 (144 + 14 ms).This establishes direct kinetic evidence for surface ethyl as the kinetically relevant intermediate. Such a direct link between the temporal behavior of an observed intermediate and the final product growth in a heterogeneous catalytic system has not been demonstrated before to our knowledge. A fraction (10 percent) of the asymptotic ethane growth at 323 K is prompt, indicating that there are surface ethyl species that react much faster than the majority of the CH3CH2Pt intermediates. The dispersive kinetics is attributed to the varying strength of interaction of the ethyl species with the Pt surface caused by heterogeneity of the surface environment. At 473 K, the …

Guiding of relativistically intense (>1018 W/cm2) laser pulses over more than 10 diffraction lengths has been demonstrated using plasma channels formed by hydrodynamic shock. Pulses up to twice the self guiding threshold power were guided without aberration by tuning the guide profile. Transmitted spectra and mode images showed the pulse remained in the channel over the entire length. Experiments varying guided mode power and simulations show a large plasma wave was driven.Operating just below the trapping threshold produces a dark current free structure suitable for controlled injection.
