Facile reaction/extraction of coal with supercritical fluids. Quarterly technical progress report, January 1-March 31, 1984
Arylmethyl phenyl ethers undergo competing reactions when treated with Lewis acids in benzene solvent. Apparently, benzene is insufficiently reactive to compete with intramolecular (intrapolymer) nucleophiles and, consequently, no increase in solubility accompanies the cleavages of ether links upon addition of benzene. When better nucleophiles, naphthalene and phenanthene, are provided, carbonium ions generated from ether cleavages are capped and the product is lower in molecular weight and more soluble. It is worth noting that the naphthalene (k/sub rel/ = 300) is nearly as good a trap as the phenol (k/sub rel/ = 450). Since hydroxylic solvents will level the acid strength of BF/sub 3/ to that of ROBF/sub 3//sup -/H/sup +/ and hydrocarbons would not, the acid-catalyzed bond cleavages necessary for unlinking coal may in fact be faster in BF/sub 3/-arene than in BF/sub 3/-phenol. While we have not yet extended these results to coals, we believe that the combination of a relatively mild Lewis acid catalyst, BF/sub 3/, with a good carbonium ion trap, naphthalene, will allow selective cleavage and capping of aryl alkyl ether bonds. 3 references, 2 figures, 3 tables.

MHD compressor---expander conversion system integrated with GCR inside a deployable reflector
This work originates from the proposal MHD Compressor-Expander Conversion System Integrated with a GCR Inside a Deployable Reflector''. The proposal concerned an innovative concept of nuclear, closed-cycle MHD converter for power generation on space-based systems in the multi-megawatt range. The basic element of this converter is the Power Conversion Unit (PCU) consisting of a gas core reactor directly coupled to an MHD expansion channel. Integrated with the PCU, a deployable reflector provides reactivity control. The working fluid could be either uranium hexafluoride or a mixture of uranium hexafluoride and helium, added to enhance the heat transfer properties. The original Statement of Work, which concerned the whole conversion system, was subsequently redirected and focused on the basic mechanisms of neutronics, reactivity control, ionization and electrical conductivity in the PCU. Furthermore, the study was required to be inherently generic such that the study was required to be inherently generic such that the analysis an results can be applied to various nuclear reactor and/or MHD channel designs''.

THE HEAT CAPACITY OF BERYLLIUM CARBIDE POWDER IN STAINLESS STEEL CAPSULES AS A FUNCTION OF TEMPERATURE (400-1800 F)
The mean heat capacity of a sample of powdered beryllium carbide, a possible moderator material for a nuclear reactor, was determined as a function of temperature. A thin-walled stainless steel capsule containing the material was heated in an electric furnace and dropped into a water calorimeter. The following linear equation for mean heat capacity over the temperature range 50 f C-T f C as a function of temperature, T, was derived from the data by the method of least squares: C/sub p/ = 0.299 + 2.16 x 10/sup -4/ T f C el temperatures 0.005 cal gm/sup -1/( f C)/sup -1/. The numerical value of C/sub p/ expressed by this equation is also equal to the mean heat capacity in Btu lb/sup -1/( f F)/sup -1/. (auth)

Development of Passive Electronic Components for Instrumentation of Improved Geothermal Logging Tools and Components. Semiannual Progress Report. Report No. 1. [For Temperatures Up to 500/sup 0/C]
Research progress is reported on the development of passive components, resistors, capacitors, metallization, and passivation, that will withstand well logging temperatures to 500/sup 0/C and have extremely low temperature coefficients. The lower the temperature coefficients, the more exacting the instrumentation designs can be without elaborate compensation techniques. The method of fabricating the thin film components is that of chemical vapor deposition (CVD) which is a major deviation from the standard approach. The films are grown in a CVD reactor by passing various reactant gases over a heated substrate. The reactor was modified in order to accommodate the gases needed in the deposition of metals. The reactor can be operated over a temperature range of 400/sup 0/C to greater than 1200/sup 0/C, and at any pressure between atmospheric and 1 x 10/sup -3/ torr. Tungsten, tungsten-silicon, and silicon nitride were successfully deposited on oxidized silicon wafers. The tungsten is used for interconnects and capacitor plates, tungsten-silicon is used as a high resistivity material for resistors, and silicon nitride is used as a dielectric for the capacitors and as a passivation layer. The materials are currently being studied in terms of their deposition parameters and electrical characteristics.

Comparison of the initial ETA gas propagation experiments with theoretical models
This report contains a description of the initial ETA propagation experiments in air at a beam current of 4.5 kA. The beam was observed to propagate at the pressures anticipated on the basis of previous theory and experiment. A comparison of measured net current waveforms with predictions of the PHOENIX code showed good agreement over the pressure range 0.1 to 200 torr. However, the beam was observed to expand with Z at a faster rate than theory predicts. Excessive transverse beam modulation at injection complicated the experiments and limited their comparison with theory.

Army Health Care: Progress Made in Staffing and Monitoring Units that Provide Outpatient Case Management, but Additional Steps Needed
A letter report issued by the Government Accountability Office with an abstract that begins "In February 2007, a series of Washington Post articles disclosed problems at Walter Reed Army Medical Center, particularly with the management of servicemembers receiving outpatient care. In response, the Army established Warrior Transition Units (WTU) for servicemembers requiring complex case management. Each servicemember in a WTU is assigned to a Triad of Care--a primary care manager, a nurse case manager, and a squad leader--who provide case management services to ensure continuity of care. The Army established staff-to-servicemember ratios for each Triad of Care position. This report examines (1) the Army's ongoing efforts to staff WTU Triad of Care positions and (2) how the Army monitors the recovery process of WTU servicemembers. GAO reviewed WTU policies, analyzed Army staffing and monitoring data, interviewed Army officials, and visited five selected WTUs."

Federal Land Management: Availability and Potential Reliability of Selected Data Elements at Five Agencies
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government manages about 650 million acres, or 29 percent, of the 2.27 billion acres of U.S. land. Four land management agencies--the Bureau of Land Management (BLM), the Fish and Wildlife Service (FWS), the National Park Service (NPS) in the Department of the Interior (Interior) and the Forest Service, in the Department of Agriculture--manage about 95 percent of these federal acres. Interior's Bureau of Reclamation (BoR) manages another 1 percent of these acres and focuses on water projects. The five agencies collect certain data to help manage these federal lands. GAO was asked to review whether the five agencies collect certain federal land and resource data (referred to as data elements), how these data elements are stored, and their potential reliability. GAO included over 100 data elements at each agency in its analysis that can be categorized as information on (1) federal land and the resources the five agencies manage, (2) revenues generated from selected activities on these lands, and (3) federal land subject to selected land use designations. GAO assessed the potential reliability of data elements collected by the agencies generally for fiscal years …

Mutual Fund Trading Abuses: Lessons Can Be Learned from SEC Not Having Detected Violations at an Earlier Stage
A letter report issued by the Government Accountability Office with an abstract that begins "Recent violations uncovered in the mutual fund industry raised questions about the ethical practices of the industry and the quality of its oversight. A widespread abuse involved mutual fund companies' investment advisers (firms that provide management and other services to funds) entering into undisclosed arrangements with favored customers to permit market timing (frequent trading to profit from short-term pricing discrepancies) in contravention of stated trading limits. These arrangements harmed long-term mutual fund shareholders by increasing transaction costs and lowering fund returns. Questions have also been raised as to why the New York State Attorney General's Office disclosed the trading abuses in September 2003 before the Securities and Exchange Commission (SEC), which is the mutual fund industry's primary regulator. Accordingly, this report (1) identifies the reasons that SEC did not detect the abuses at an earlier stage and the lessons learned in not doing so, and (2) assesses the steps that SEC has taken to strengthen its mutual fund oversight program and improve mutual fund company operations."

Designated Federal Entities: Survey of Governance Practices and the Inspector General Role
A letter report issued by the Government Accountability Office with an abstract that begins "For entities that rely on others for funding, effective governance, accountability, and internal control are keys to maintaining trust and credibility. In recent years, corporate governance and accountability have received increased scrutiny and emphasis in the nonprofit, federal government, and public company sectors. Governance and accountability problems have also been identified at designated federal entities (DFE) such as the Smithsonian Institution, the Legal Services Corporation, and the Pension Benefit Guaranty Corporation. This report responds to a congressional request that GAO describe (1) the statutory structure of the governing bodies for each DFE organization and (2) the role of the inspectors general (IGs) in the governance structure. To accomplish this, GAO surveyed the DFE heads and IGs on governance issues and reviewed information from a variety of sources, including the IG Act and subsequent amendments; enabling legislation for the DFEs; and legislative and regulatory standards and requirements for financial reporting and internal control. GAO is not making specific recommendations in this report, but is providing this information for consideration in future efforts to update the governance of DFEs, oversee the entities and their IGs, and continue work …

Federal Rulemaking: Improvements Needed to Monitoring and Evaluation of Rules Development as Well as to the Transparency of OMB Regulatory Reviews
A letter report issued by the Government Accountability Office with an abstract that begins "Regulation is one of the principal tools that the government uses to implement public policy. As part of the rulemaking process federal agencies must comply with an increasing number of procedural and analytical requirements. GAO was asked to examine how broadly applicable rulemaking requirements cumulatively have affected (1) agencies' rulemaking processes, in particular including effects of requirements added to the process since 2003, and (2) transparency of the Office of Information and Regulatory Affairs (OIRA) regulatory review process. To address these objectives, GAO reviewed selected rules issued between January 2006 and May 2008 and associated dockets and also interviewed knowledgeable agency and OIRA officials."

Human Capital: Opportunities to Improve Federal Continuity Planning Guidance
A letter report issued by the General Accounting Office with an abstract that begins "Federal agencies must have the capacity to serve the public during disruptions to normal operations. This depends, in part, on continuity efforts that help agencies marshal, manage, and maintain their most important asset--their people, or human capital. GAO identified the human capital considerations relevant to federal continuity efforts; described efforts by the Federal Emergency Management Agency (FEMA) and the Office of Personnel Management (OPM) to address these considerations relevant to continuity of operations (COOP); and described the role Federal Executive Boards (FEB) play in coordinating such efforts outside Washington, D.C."

IRS Offers in Compromise: Performance Has Been Mixed; Better Management Information and Simplification Could Improve the Program
A letter report issued by the Government Accountability Office with an abstract that begins "Taxpayers unable to fully pay their tax liabilities may apply for an offer in compromise (OIC), an agreement with IRS to pay what they can afford. IRS writes off the rest of the liability. In 2005, IRS accepted over 14,000 offers. Because of concerns about program performance and a new category of offers based on exceptional circumstances, GAO was asked to (1) describe the trends in program's performance and their causes and (2) determine whether IRS's regulations for exceptional circumstance offers are consistent with statute. GAO examined five program objectives: timeliness, quality, accessibility, compliance, and cost."

Global Health: USAID Supported a Wide Range of Child and Maternal Health Activities, but Lacked Detailed Spending Data and a Proven Method for Sharing Best Practices
A letter report issued by the Government Accountability Office with an abstract that begins "Every year, disease and other conditions kill about 10 million children younger than 5 years, and more than 500,000 women die from pregnancy and childbirth-related causes. To help improve their health, Congress created the Child Survival and Health Programs Fund. The 2006 Foreign Operations Appropriations Act directed GAO to review the U.S. Agency for International Development's (USAID) use of the fund for fiscal years 2004 and 2005. Committees of jurisdiction indicated their interest centered on the Child Survival and Maternal Health (CS/MH) account of the fund. GAO examined USAID's (1) allocations, obligations, and expenditures of CS/MH funds; (2) activities undertaken with those funds; (3) methods for disseminating CS/MH information; and (4) response to challenges to its CS/MH programs. GAO conducted surveys of 40 health officers, visited USAID missions in four countries, interviewed USAID officials, and reviewed data."

Child and Family Services Reviews: Better Use of Data and Improved Guidance Could Enhance HHS's Oversight of State Performance
A letter report issued by the General Accounting Office with an abstract that begins "In 2001, the Department of Health and Human Services' (HHS) Administration for Children and Families (ACF) implemented the Child and Family Services Reviews (CFSR) to increase states' accountability. The CFSR uses states' data profiles and statewide assessments, as well as interviews and an on-site case review, to measure state performance on 14 outcomes and systemic factors, including child well-being and the provision of caseworker training. The CFSR also requires progress on a program improvement plan (PIP); otherwise ACF may apply financial penalties. This report examines (1) ACF's and the states' experiences preparing for and conducting the statewide assessments and on-site reviews; (2) ACF's and the states' experiences developing, funding, and implementing items in PIPs; and (3) any additional efforts that ACF has taken beyond the CFSR to help ensure that all states meet federal goals related to children's safety, permanency, and well-being."

Contract Management: Benefits of Simplified Acquisition Test Procedures Not Clearly Demonstrated
A letter report issued by the General Accounting Office with an abstract that begins "In 1996, Congress authorized a test program that permits government buyers to use procedural discretion and flexibility, so that commercial items may be obtained in a simplified manner. This report discusses how federal agencies demonstrated whether the test program produced the desired results and (2) assesses how the authority provided under the test program was being used on selected contracts. GAO found that (1) the Office of Federal Procurement Policy did not collect data to provide a basis for measuring whether the test program produced the desired results and (2) government buyers did not always demonstrate that prices were fair and reasonable for the contracts included in GAO's review. However, OFPP's 1999 survey of procurement executives showed that these executives believed that the program has had a positive impact on the federal procurement process. These executives believed that the authority provided under the test program should be made permanent. However, OFPP's survey did not collect empirical data that would have supported these views."

Investigation of methods to transfer heat from solar liquid-heating collectors to heat storage tanks. Final report
A study was made of the methods available to transfer heat from the collector to the water storage tank in water heating systems. In counterflow heat exchangers used in double loop water heating systems, it was found to be more important to use a high water flowrate than a high heat transfer fluid flowrate. It was earlier thought to be best to have matched WC/sub p/ (mass flowrate-specific heat) products in the loops. It was shown in this study that the water WC/sub p/ product should be about twice as large as that of the heat transfer fluid. It was found that neither the heat exchanger type nor the size was very critical, so that very simple criteria were adequate in determining optimum heat exchanger size. It was found that there is a definite system size below which one should use a traced tank or a coil in a tank. Equations and optimization criteria were developed for traced tanks or tanks with coils. At present, there is no quantitative understanding of liquid to liquid (direct contact) heat exchangers, though they are clearly quite effective. Draindown systems are discussed, and several appendices are included on heat transfer and other characteristics of …
