Stream sediment detailed geochemical survey for Marysvale, Utah
Results of the Marysvale detailed geochemical survey are reported. Field and laboratory data are presented for 397 stream sediment samples and 160 radiometric readings. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Stream sediments containing significant amounts of soluble uranium (greater than or equal to 16.93 ppM) occur in numerous areas, the most prevalent being in the western portion of the survey area, within and surrounding the Mount Belknap Caldera. Thorium, beryllium, cerium, manganese, molybdenum, niobium, potassium, yttrium, zinc, and zirconium occur in concentrations greater than or equal to 84th percentile in many sediment samples taken from within and surrounding the Mount Belknap Caldera. The uranium and related variables are associated with highly silicic intrusions and extrusions of the Mount Belknap Volcanics, as well as hydrothermal activity which has occurred in the Marysvale volcanic field.

Study on reduction of accessory horsepower requirements. Eighth quarterly progress report
This is the eighth quarterly technical progress report for a program in which the objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The current Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: the test vehicle was successfully driven to and from Ann Arbor, Michigan from Phoenix with the drive system installed; accessory drive hardware was calibrated, disassembled and reviewed for wear after round trip from Phoenix to Ann Arbor, Michigan; MADS governor performance was analyzed and parameters were varied to demonstrate flexibility available in modifying accessory drive input/output characteristics; and a task list that matched smaller, lower cost accessory components, with the accessory drive equipped vehicle, was prepared. Major emphasis during the remainder of the program will be in this area. (LCL)

Silicon-on ceramic process. Silicon sheet growth and device development for the large-area silicon sheet and cell development tasks of the low-cost solar array project. Quarterly report No. 12, April 2, 1979-June 29, 1979
The objective of this research program is to investigate the technical and economic feasibility of producing solar-cell-quality sheet silicon. We plan to do this by coating one surface of carbonized ceramic substrates with a thin layer of large-grain polycrystalline silicon from the melt. During the quarter, significant progress was demonstrated in several areas: (1) a 10-cm/sup 2/ cell having 9.9 percent conversion efficiency (AM1, AR) was fabricated; (2) the Honeywall-sponsored SCIM coating development succeeded in producing a 225-cm/sup 2/ layer of sheet silicon (18 inches x 2 inches); and (3) 100 ..mu..m-thick coatings at pull speed of 0.15 cm/sec wer$obta9ned, although apoproximately 50 percent of the layer exhibited dendritic growth. Other results and accomplishments during the quarter are reported in detail. (WHK)

Effect of fluoride, chloride, bromide, and thiocynate on potentiometric titrations of iron(II)-tin(II) mixtures with cerium(IV)
A two-step curve is expected in the potentiometric titration of Fe(II)-Sn(II) mixtures with Ce(IV) in H/sub 2/SO/sub 4/. Each end point should indicate the respective oxidation of Sn(II) and Fe(II). However, experimentally only one end point was found; it corresponded to the total oxidation of Sn(II) and Fe(II). When this oxidation-reduction reaction was carried out in the presence of Cl/sup -/, the theoretical behavior was observed. The present study was done to ascertain if monovalent anions other than Cl/sup -/ have a similar effect on this oxidation-reduction system. The monovalent species F/sup -/, Br/sup -/, and SCN/sup -/ were selected for this study, and the results indicate that each affects the rate of reaction relative to the ease of oxidation of the individual ions.

Brayton-cycle heat recovery-system characterization program. Subatmospheric-system test report
The turbine tests and results for the Brayton cycle subatmospheric system (SAS) are summarized. A scaled model turbine was operated in the same environment as that which a full-scale SAS machine would experience from the hot effluent flue gas from a glass container furnace. The objective of the testing was to evaluate the effects of a simulated furnace flue gas stream on the turbine nozzles and blades. The following specific areas were evaluated: erosion of the turbine nozzles and blades from the dust in the flue gas, hot corrosion from alkali metal salts in the dust and acid vapor (sulfur trioxide and hydrogen chloride) in the flue gas, and fouling and flow blockage due to deposition and/or condensation from the flue gas constituents.

Demonstration plant supplementary technical studies section 10-confidence analysis. SRC-II demonstration project, phase zero, task number 1, deliverable number 3
The Gulf Management Sciences Group (GMSG) in Pittsburgh was asked to provide assistance in performing a confidence analysis for the SRC-II demonstration plant as required by the Department of Energy. Specifically, the contract says to discuss confidence levels for plant operating and capital costs; plant operability and technical risk. It was decided that the best way to obtain estimates for these variables would be through interviews of people with substantial experience in the field. Each subject was first asked what modifications he envisioned being made to the current plant design. Discussion was limited to major systems that might require partial redesign and comments concerning the plant in general. The interviewees were next asked to estimate the probability of success for the project, given that the modifications they envisioned were in fact made. The modes of the combined distributions of the interview results indicate that the respondents in general felt that the base case estimates represented the most probable outcomes with the possible exception of the capital cost estimate. On the other hand, the respondents consistently judged that there is a chance that the demonstration plant will perform significantly worse than the base case for each of the variables that were …

Border Security: Security of New Passports and Visas Enhanced, but More Needs to Be Done to Prevent Their Fraudulent Use
A letter report issued by the Government Accountability Office with an abstract that begins "Travel documents are often used fraudulently in attempts to enter the United States. The integrity of U.S. passports and visas depends on the combination of well-designed security features and solid issuance and inspection processes. GAO was asked to examine (1) the features of U.S. passports and visas and how information on the features is shared; (2) the integrity of the issuance process for these documents; and (3) how these documents are inspected at U.S. ports of entry. We reviewed documents such as studies, alerts, and training materials. We met with officials from the Departments of State, Homeland Security, and Commerce's National Institute of Standards and Technology, and U.S. Government Printing Office, and with officials at seven passport offices, nine U.S. ports of entry, two U.S. consulates in Mexico, and two Border Crossing Card production facilities."

Information Technology: Agencies Need to Establish Comprehensive Policies to Address Changes to Projects' Cost, Schedule, and Performance Goals
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government plans to spend about $70 billion on information technology (IT) projects during fiscal year 2008. Consequently, it is important that projects be managed effectively to ensure that public resources are wisely invested. At times, a project's cost, schedule, and performance goals--known as its baseline--are modified to reflect changed development circumstances. These changes--called a rebaselining--can be done for valid reasons, but can also be used to mask cost overruns and schedule delays. GAO was asked to (1) determine the extent of and the primary reasons for IT project rebaselining and (2) determine whether federal agencies have sound policies for rebaselining projects. To do this, GAO surveyed the managers of a random sample of 180 projects selected from the 778 major IT projects the 24 major agencies plan to invest in during fiscal year 2008. GAO also compared agencies' rebaselining policies to best practices."

NASA: Status of Achieving Key Outcomes and Addressing Major Management Challenges
A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the National Aeronautics and Space Administration's (NASA) fiscal year 2000 performance report to assess the agency's progress in achieving selected key outcomes important to NASA's mission. The selected key outcomes are to (1) expand scientific knowledge of the Earth system, (2) expand the commercial development of space, and (3) deploy and operate the International Space Station safely and cost effectively. NASA reported mixed progress in achieving these key outcomes. In general, NASA's strategies for achieving unmet performance targets for theses outcomes are clear and reasonable. NASA achieved most targets related to expanding knowledge of the Earth system. However, its progress in other areas was more limited. NASA has made improvements in its fiscal year 2000 performance report in comparison to its fiscal year 1999 performance report. Specifically, NASA describes its verification and validation efforts and discloses its data sources for each performance target. NASA's report partially addressed the governmentwide high-risk area of strategic human capital management but not the area of information security. GAO has previously found that NASA lacks an effective agencywide security program. NASA's report only addressed two of the three critical …

Rental Housing Programs: Excluding Servicemembers' Housing Allowances from Income Determinations Would Increase Eligibility, but Other Factors May Limit Program Use
A letter report issued by the Government Accountability Office with an abstract that begins "Although the Department of Defense (DOD) pays active-duty servicemembers who do not live in military housing a Basic Allowance for Housing (BAH) to help them afford private market residences, expected growth at some military installations has raised concerns about whether nearby communities will have enough affordable rental housing for incoming personnel. In response to a congressional mandate, GAO assessed (1) how excluding BAH would affect servicemembers' eligibility to apply for federal rental housing programs and (2) factors that could affect their use of the programs in selected communities gaining military personnel. GAO compared servicemembers' eligibility for the programs as of December 2005 by including and excluding BAH from income determinations and examined factors affecting potential program use near four growing military installations."

Contingency Contract Management: DOD Needs to Develop and Finalize Background Screening and Other Standards for Private Security Contractors
A letter report issued by the Government Accountability Office with an abstract that begins "Currently in Iraq, there are thousands of private security contractor (PSC) personnel supporting DOD and State, many of whom are foreign nationals. Congressional concerns about the selection, training, equipping, and conduct of personnel performing private security functions in Iraq are reflected in a provision in the fiscal year 2008 National Defense Authorization Act (NDAA) that directs DOD to develop guidance on PSCs. This report examines the extent (1) that DOD and State have developed and implemented policies and procedures to ensure that the backgrounds of PSC employees have been screened and (2) that DOD has developed guidance to implement the provisions of the NDAA and (3) that DOD and State have addressed measures on other issues related to PSC employees in Iraq. To address these objectives, GAO reviewed DOD and State guidance, policies, and contract oversight documentation and interviewed agency and private security industry officials."

Drug-Free Communities Support Program: Stronger Internal Controls and Other Actions Needed to Better Manage the Grant-Making Process
A letter report issued by the Government Accountability Office with an abstract that begins "Twenty-five percent of American students ages 13-17 reported using illicit drugs in 2007. The Drug-Free Communities Support Program provides grants to community coalitions involved in reducing youth substance abuse. The Office of National Drug Control Policy (ONDCP) administers the program. ONDCP selected the Substance Abuse and Mental Health Services Administration (SAMHSA) to operate the grant program in fiscal year 2005. In 2005, ONDCP did not award grants to some coalitions who had previously received grant funds (renewal grantees). GAO was asked to assess (1) the extent to which ONDCP and SAMHSA administered grant-related activities for fiscal years 2005 and 2006 consistent with federal internal control standards, statutory requirements, and other guidance and (2) the steps ONDCP has taken since 2006 regarding its administration of grant-related activities. GAO analyzed and compared program documents and grant activities to established guidance, such as federal internal control standards and statutory requirements, and interviewed key program management officials."

Home Mortgages: Provisions in a 2007 Mortgage Reform Bill (H.R. 3915) Would Strengthen Borrower Protections, but Views on Their Long-term Impact Differ
A letter report issued by the Government Accountability Office with an abstract that begins "H.R. 3915 (2007), a bill introduced, but not enacted by the 110th Congress, was intended to reform mortgage lending practices to prevent a recurrence of problems in the mortgage market, particularly in the nonprime market segment. The bill would have set minimum standards for all mortgages (e.g., reasonable ability to repay) and created a "safe harbor" for loans that met certain requirements. Securitizers of safe harbor loans would be exempt from liability provisions, while securitizers of non-safe harbor loans would be subject to limited liability for loans that violated the bill's minimum standards. In response to a congressional request, this report discusses (1) the proportions of recent nonprime loans that likely would have met and not met the bill's safe harbor requirements and factors influencing the performance of these loans, and (2) relevant research and the views of mortgage industry stakeholders concerning the potential impact of key provisions of the bill on the availability of mortgage credit. To do this work, GAO analyzed a proprietary database of securitized nonprime loans, reviewed studies of state and local anti-predatory lending laws, and met with financial regulatory agencies and …

Medigap Insurance: Plans Are Widely Available but Have Limited Benefits and May Have High Costs
A letter report issued by the General Accounting Office with an abstract that begins "To protect themselves against large out-of-pocket expenses and help fill gaps in Medicare coverage, most beneficiaries buy supplemental insurance, known as Medigap; contribute to employer-sponsored health benefits to supplement Medicare coverage; or enroll in private Medicare+Choice plans rather than traditional fee-for-service Medicare. Because Medicare+Choice plans are not available everywhere and many employers do not offer retiree health benefits, Medigap is sometimes the only supplemental insurance option available to seniors. Medicare beneficiaries who buy Medigap plans have coverage for essentially all major Medicare cost-sharing requirements, including coinsurance and deductibles. But this "first-dollar" coverage may undermine incentives for prudent use of Medicare services, which could ultimately boost costs for the Medicare program. Although various proposals have been made to add a prescription drug benefit to Medicare, relatively few beneficiaries buy standardized Medigap plans with this benefit. Low enrollment in these plans may be due to the fact that fewer plans are being marketed with these benefits; their relatively high cost; and the limited nature of their prescription drug benefit, which still requires beneficiaries to pay more than half of their prescription drug costs. Most plans have a $3,000 …
