Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report (open access)

Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report

Short term objectives for well-logging instrumentation are circuits which can operate at temperatures in the range 275/sup 0/C to 350/sup 0/C; the medium term goal is operation up to 500/sup 0/C, and the long term goal is to achieve operation at 1000/sup 0/C. It is apparent that useful electronic circuits will require the combination of both passive components and active devices. In order to meet the compatibility requirements, the basic technology which has been selected in this project is the chemical vapor deposition of metal interconnections, resistor material, dielectric material and passivating material. It is to be emphasized that this is a thin-film, not thick-film, technology which is compatible with the processing methods used in fabricating either semiconductor or integrated thermionic devices, and produces components which are electrically compatible with those devices. The investigation in this project is primarily directed toward tungsten metallization, tungsten-silicon resistors, and silicon nitride dielectric and passivation.

In Vivo Gamma Lung Measurements--a Mathematical Model (open access)

In Vivo Gamma Lung Measurements--a Mathematical Model

A low-background facility is described for rneasuring lung burdens of U, Th, and other nuclides in vivo. Problems associated with this method of radiation measurement are discussed. A mathennatical, computer-oriented simulation was devised to gain insight into the relation of the net observed radiation spectrum to the burden of radioactivity in the body or its organs. Chest cavities for persons of three sizes were synthesized in a three-coordinate space comprised of one-inch cubes and including a 9-in.-diameter crystal detector. Data, describing the tissue composition of each cube in the body and the characteristic radiation attenuation for each tissue-type, were coded for use with a program on a high-speed digital computer. Efficiencies for measuring radiation emitted by numerous point sources of enriched uranium were calculated. Data on in vivo measurement efficiency were obtained assuming uniform distribution of radioactive material throughout the lungs and also for nonuniform deposits. The effects of individual size and geometry, and of detector position on the measurement efficiency were determined for these twvo categories and radiation flux distributions on the detector face were computed in some cases. Data are appended and a flow diagram of the computer program is included. (C.H.)

Inelastic Strong Interactions at High Energies. [Cross Sections, Field Theory] (open access)

Inelastic Strong Interactions at High Energies. [Cross Sections, Field Theory]

A method permitting the calculation of inclusive and semi-inclusive cross sections at high energies starting from an arbitrary field theory was worked out. The method relies on a functional integral representation of the generating functional of inclusive cross sections and on the use of semiclassical methods. The inclusive cross section is proportional to the absolute square of the Fourier transform of a special soliton solution of the classical field equations in zeroth order semi-classical approximation. A conserved topological quantum number that has a nonzero value for the soliton solution was found. Future research to be performed in this field under the contract is described including applications to various field theories and the exploration of connections with Reggeon field theory.

Plutonium Residue Recovery (PuRR) project quarterly progress report, April--June 1989 (open access)

Plutonium Residue Recovery (PuRR) project quarterly progress report, April--June 1989

A material-balance flowsheet for ash-heel processing has been prepared. The major process features are (1) reduction of Pu into a calcium-zinc alloy and selective electrolytic recovery of the Pu from the alloy, (2) removal of americium as a waste, (3) concentration of nontransuranic tramp elements in a zinc waste, (4) removal of oxygen and recovery of calcium by electrolysis of CaO, and (5) zinc recycle by evaporation. Based on this idealized flowsheet, the mass of solid waste is only 62% of that of the original residue. This is accomplished by recycling virtually all the reagents and discarding the oxygen as CO and CO{sub 2}. The pyrochemical recovery of Pu from incinerator ash heel from the Rocky Flats Plant was investigated. During this period, zinc-calcium alloys were used to reduce the PuC{sub 2} in the ash. Reduction of ash heel has been attempted with zinc-calcium alloys containing 2, 6, and 10 wt% calcium after the reduction. These resulted in extractions of 95%, 97%, and 99.5%, respectively, of the Pu from the salt. Following exposure of the reduction alloy to a ZnCl{sub 2}-bearing salt, the Pu was removed effectively from the alloy; however, the Pu recovered in the salt did not complete …

U.S. Department of Agriculture: Internal Control Would Improve Accountability for Certain Centrally Provided (Greenbook) Programs (open access)

U.S. Department of Agriculture: Internal Control Would Improve Accountability for Certain Centrally Provided (Greenbook) Programs

A letter report issued by the Government Accountability Office with an abstract that begins "The Senate report accompanying the U.S. Department of Agriculture's (USDA) fiscal year 2008 appropriations expressed concern that USDA's Greenbook charges--the transfer of funds authority USDA used to charge the appropriations accounts of its agencies and staff offices for programs to centrally provide certain services--had grown excessively. USDA's Office of the Chief Financial Officer (OCFO) oversees Greenbook charges. The report directed GAO to review these charges and USDA to report on them. This report identifies the agencies and offices assessed Greenbook charges, the amounts of the charges, and the programs supported by Greenbook charges for fiscal years 1999 through 2009. It also (1) assesses how USDA selected programs and monitored Greenbook charges and (2) describes the benefits of the programs, as reported by USDA. GAO reviewed and assessed USDA budget and program documents and discussed processes with officials."

Managing Sensitive Information: DOJ Needs a More Complete Staffing Strategy for Managing Classified Information and a Set of Internal Controls for Other Sensitive Information

A letter report issued by the Government Accountability Office with an abstract that begins "The September 11 attacks showed that agencies must balance the need to protect and share sensitive information to prevent future attacks. Agencies classify this information or designate it sensitive but unclassified to protect and limit access to it. The National Archives' Information Security Oversight Office (ISOO) assesses agencies' classification management programs, and in July 2004 and April 2005 recommended changes to correct problems at the Justice Department (DOJ) and Federal Bureau of Investigation (FBI). GAO was asked to examine (1) DOJ's and FBI's progress in implementing the recommendations and (2) the management controls DOJ components have to ensure the proper use of sensitive but unclassified designations. GAO reviewed ISOO's reports and agency documentation on changes implemented and controls in place, and interviewed security program managers at DOJ, its components, and ISOO to examine these issues."

Homeland Security: Opportunities Exist to Enhance Collaboration at 24/7 Operations Centers Staffed by Multiple DHS Agencies

A letter report issued by the Government Accountability Office with an abstract that begins "Because terrorists do not operate on a 9-5 schedule, the Department of Homeland Security (DHS) and its operational components have established information gathering and analysis centers that conduct activities 24 hours a day, 7 days a week, 365 days a year. Staff at these operations centers work to help detect, deter, and prevent terrorist acts. DHS has determined that out of 25 operations centers, four require higher levels of collaboration that can only be provided by personnel from multiple DHS agencies, and other federal, and sometimes state and local, agencies. For these four multi-agency operations centers, this report (1) describes their missions, products, functions, and customers and (2) assesses the extent to which DHS efforts to promote collaboration among the multiple agencies responsible for the centers reflect key practices for enhancing and sustaining collaborative efforts. To do so, GAO visited operations centers, reviewed data and reports from the centers, and interviewed center and other DHS officials."

Adoption Tax Credit: IRS Can Reduce Audits and Refund Delays (open access)

Adoption Tax Credit: IRS Can Reduce Audits and Refund Delays

A letter report issued by the Government Accountability Office with an abstract that begins "The federal adoption tax credit, established in 1996, was amended in 2010. These amendments included making the credit refundable (meaning taxpayers could receive payments in excess of their tax liability) and increasing the maximum allowable credit to $13,170 of qualified adoption expenses for tax year 2010. As of August 20, 2011, taxpayers filed just under 100,000 returns, claiming about $1.2 billion in adoption credits. Following these changes, the Internal Revenue Service (IRS) developed a strategy for processing adoption credit claims. GAO was asked to (1) describe IRS's strategy for ensuring compliance with the adoption credit for the 2011 filing season, (2) assess IRS's related communication with taxpayers and stakeholders, and (3) assess its processing and audit of claims. To conduct its analysis, GAO analyzed IRS data and documents, interviewed IRS officials, observed IRS examiners, and interviewed other stakeholders."

Intragovernmental Revolving Funds: NIST's Interagency Agreements and Workload Require Management Attention (open access)

Intragovernmental Revolving Funds: NIST's Interagency Agreements and Workload Require Management Attention

A letter report issued by the Government Accountability Office with an abstract that begins "GAO previously found that a significant portion of the National Institute of Standards and Technology's (NIST) working capital fund contained a growing carryover balance. Almost all of the fund's resources come from appropriations advanced from federal clients for NIST's technical services through interagency agreements. Monitoring and tracking key information about agreements and the funds advanced for them is critical for both NIST and its clients to make well-informed budget decisions, comply with applicable fiscal laws and internal controls, and ensure the proper use of federal funds. GAO was asked to review (1) the factors contributing to the working capital fund's carryover balance and (2) NIST's processes for managing its interagency agreements and workload. To do so, GAO reviewed laws and fiscal requirements, analyzed NIST budget data and policies related to its interagency agreements, analyzed a random sample of agreements, and interviewed NIST officials."

Commercial Space Launches: FAA Needs Continued Planning and Monitoring to Oversee the Safety of the Emerging Space Tourism Industry

A letter report issued by the Government Accountability Office with an abstract that begins "In 2004, the successful launches of SpaceShipOne raised the possibility of an emerging U.S. commercial space tourism industry that would make human space travel available to the public. The Federal Aviation Administration (FAA), which has responsibility for safety and industry promotion, licenses operations of commercial space launches and launch sites. To allow the industry to grow, Congress prohibited FAA from regulating crew and passenger safety before 2012, except in response to high-risk events. GAO evaluated FAA's (1) safety oversight of commercial space launches, (2) response to emerging issues, and (3) challenges in regulating and promoting space tourism and responding to competitive issues affecting the industry. GAO reviewed FAA's applicable safety oversight processes and interviewed federal and industry officials."

The Challenge of Data Sharing: Results of a GAO-Sponsored Symposium on Benefit and Loan Programs

A letter report issued by the General Accounting Office with an abstract that begins "Data sharing among federal agencies that run federal benefit and loan programs is important for determining the eligibility of applicants and beneficiaries. A GAO symposium on data sharing highlighted various issues facing federal agencies in their efforts to prevent abuse of federal programs. Symposium speakers focused on the number of program dollars saved by interagency data exchanges. Agencies using computer matching have detected undisclosed income and welfare recipients who receive benefits from more than one state. Improved technologies offer agencies the opportunity to expand their data sharing efforts. Such technologies include computer systems that can communicate directly with other systems and computer networks that can obtain information directly from financial institutions. Symposium speakers agreed that applicants' privacy should be protected when personal information is shared among agencies, but they disagreed about the extent to which data sharing threatens it. Privacy laws and security-related technology provide individuals with some protection against the possible misuse of personal information, but symposium participants differed on whether these protections are adequate."

Managing for Results: Federal Managers' Views Show Need for Ensuring Top Leadership Skills (open access)

Managing for Results: Federal Managers' Views Show Need for Ensuring Top Leadership Skills

A letter report issued by the General Accounting Office with an abstract that begins "Through the Government Performance and Results Act (GPRA), Congress has sought to improve federal management and instill a greater focus on results. Congress and the executive branch recognize, however, that performance improvements do not take place merely because a set of management requirements has been put in place. In 1997 and 2000, GAO surveyed agencies' progress towards establishing a focus on results. GAO found that progress has been uneven in building the organizational cultures to create and sustain a focus on results governmentwide. A significantly higher percentage of managers in 2000 than in 1997 reported that their agencies had provided, arranged, or paid for training that would help them accomplish two results-oriented management-related tasks: setting performance goals and implementing the requirements of GPRA. Overall, the survey results show that, in some keys areas, agencies may be losing ground in their efforts towards building organizational cultures that support a focus on results. In GAO's view, the Senate confirmation process must ensure that political nominees have the appropriate management and leadership skills needed to continue to transform federal agencies into high-performing organizations."

Cover-gas seal program. Test report - sodium dip-seal wetting study. [at 450/sup 0/F]

This report documents the tests conducted to find a reliable surface preparation method of treating the CRBRP dip seal blade (SA508 Class 2 steel) to insure its sodium wettability at 450F or less. Two techniques were established which depressed the sodium wetting temperature of SA 508, Class 2 dip seal blade material to 375F. These techniques were depositing an approx. 60 x 10/sup -6/ inch layer of tin on the blade surface by a brush-on plating process, and, by cleaning the blade surface with ultrasonics while it is immersed in sodium. The tin plating technique is recommended as the initial and primary surface preparation method and ultrasonics as a rewetting and backup technique. This work was conducted in support of the Sodium Dip Seal Feature Test, DRS 32.05.

Desalting sea water and brackish waters: a cost update

This report, based on first-quarter 1977 dollars, is an update of costs presented in ORNL/TM-5070 (Rev.), which gave cost estimates for desalting seawater and brackish waters based on first-quarter 1975 financial parameters. Cost estimates are given for desalting seawater by distillation and reverse osmosis and for brackish waters using reverse osmosis and electrodialysis. Cost data were computed as a function of plant size and energy cost. The cost of generating steam and electrical energy on-site using coal-fired boilers as well as oil-fired boilers and dual-purpose electric/seawater distillation plants is included. While the costs of energy, equipment and labor have continued to rise, they have increased at a relatively modest rate compared with the two years prior to 1975. On an average, the cost of desalting seawater by distillation has increased approximately 15%. Costs for desalting brackish waters by the membrance processes have increased about 7%.
