236-Z canyon utilization study (open access)

236-Z canyon utilization study

The 236-Z canyon contains equipment for repurification of plutonium and recovery of plutonium from scrap material. To meet production requirements of Fast Flux Test Facility/Clinch River Breeder Reactor oxide with the existing plant, several new pieces of equipment will be needed in the future. More storage space and a better accountability system are needed to support this increased production. The available canyon space needs to be utilized to its fullest in order to accommodate the new equipment. The purpose of this document is to identify the new pieces of equipment, show how they fit into the flowsheet, and locate them in the canyon.

Development of copper sulfide/cadmium sulfide thin-film solar cells (open access)

Development of copper sulfide/cadmium sulfide thin-film solar cells

The most important accomplishments during this period were to demonstrate and to elucidate further the complex effects that occur during the aging of Cu/sub 2/S/CdS thin-film solar cells in flowing wet oxygen. There are two distinct effects. At constant illumination, the short-circuit current of cells aged at room temperature consistently decreases with time. The second effect, related to diode opposing current, is more involved and may result from several competing mechanisms. Over the short term (approx. 4 to 5 hours), the magnitude of diode opposing current decreases. After approx. 20 hours of aging, opposing current generally returns to the level achieved after hydrogen annealing which immediately preceded the aging sequence. Optical measurements of the spectral transmission of the Cu/sub 2/S layers in a cell content have been made using a silicon detector epoxied to the back of a CdS cell after the copper foil substrate was removed. There is no significant change in Cu/sub 2/S transmission behavior for wavelengths ranging from 525 to 1000 nm during wet-oxygen aging for periods of 2 to 36 hours. This suggests that the decrease in J/sub SC/ at constant illumination, for the aging experiments in a flowing wet-oxygen ambient, arises because of changes in …

Best Practices: Better Matching of Needs and Resources Will Lead to Better Weapon System Outcomes (open access)

Best Practices: Better Matching of Needs and Resources Will Lead to Better Weapon System Outcomes

A chapter report issued by the General Accounting Office with an abstract that begins "This report examines how best practices offer improvements to the way the Department of Defense defines and matches weapon system requirements to available resources such as cost, schedule, and mature technologies. GAO identified three factors that were key to matching needs and resources before product development began. First, developers employed the technique of systems engineering to identify gaps between resources and customer needs before committing to a new product development. Second, customers and developers were flexible. Leeway existed to reduce or defer customer needs to future programs or for the developer to make an investment to increase knowledge about a technology or design feature before beginning product development. Third, the roles and responsibilities of the customer and the product developer were matched, with the product developer being able to determine or significantly influence product requirements. In cases where these factors were not present at program launch, product development began without a match between requirements and resources. Invariably, this imbalance favored meeting customer needs by adding resources, which resulted in increased costs and later deliveries."

Congressional Oversight: FAA Case Study Shows How Agency Performance, Budgeting, and Financial Information Could Enhance Oversight (open access)

Congressional Oversight: FAA Case Study Shows How Agency Performance, Budgeting, and Financial Information Could Enhance Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "Pursuant to various statutes, federal agencies develop an abundance of performance, budget, and financial information that could be useful for Congress' review and monitoring of agencies. However, agencies' understanding of Congress' information needs is often limited and agencies may not be providing timely information in a format that aids congressional understanding of trends and issues. Thus, Members and their staff may not be aware of or avail themselves to certain information. To describe the information available and how it might be used to support congressional oversight, the Federal Aviation Administration was selected as a case study in part due to the large quantity of information already available. GAO was asked to identify: (1) information FAA produces that could enhance congressional oversight, (2) other technology and information resources that could enhance congressional oversight, and (3) how committee access to FAA's information could be improved to enhance its timeliness and usefulness."

Army Corps of Engineers: Peer Review Process for Civil Works Project Studies Can Be Improved

A letter report issued by the Government Accountability Office with an abstract that begins "Since enactment of the Water Resources Development Act of 2007, 49 project studies have undergone peer review but it is unclear how many were performed in response to section 2034 requirements because the Army Corps of Engineers (Corps) does not make specific determinations or track if a peer review is being conducted under section 2034. In February 2011, in response to section 2034, the Corps submitted its initial report to Congress summarizing its implementation of the peer review process. In its report, however, the Corps did not distinguish which studies had been selected for peer review in accordance with section 2034 and therefore, did not provide Congress information that would help decision makers evaluate the requirements of section 2034 at the end of the trial period."

VA Student Financial Aid: Management Actions Needed to Reduce Overlap in Approving Education and Training Programs and to Assess State Approving Agencies

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2006, the Department of Veterans Affairs (VA) paid approximately $2.1 billion in education assistance benefits to more than 470,000 beneficiaries and about $19 million to state approving agencies (SAA) to assess whether schools and training programs offer education of sufficient quality for veterans to receive VA education assistance benefits when attending them. Qualified individuals--veterans, service persons, reservists, and certain spouses and dependents--receive benefits through a number of education assistance programs for the pursuit of various types of programs, such as a degree program, vocational program, apprenticeship, or on-the-job training. The Departments of Education (Education) and Labor (Labor) also assess education and training programs for various purposes, primarily for awarding student aid and providing apprenticeship assistance. In 2006, under Title IV of the Higher Education Act, Education provided nearly $77 billion in student aid in the form of both grants and loans. The Department of Education assesses and certifies postsecondary institutions for participation in Title IV programs through various oversight functions to ensure that these schools meet federal administrative and financial requirements and that they are accredited and licensed. Similarly, under the National Apprenticeship …

Offshore Oil and Gas Development: Additional Guidance Would Help Strengthen the Minerals Management Service's Assessment of Environmental Impacts in the North Aleutian Basin

A letter report issued by the Government Accountability Office with an abstract that begins "Interest has re-emerged in developing oil and gas in the nation's offshore areas, such as the North Aleutian Basin. Located on the outer continental shelf (OCS) where the Aleutian Islands meet the Alaskan mainland around Bristol Bay, the basin may contain sizable oil and gas deposits, although the area's environmental and cultural sensitivity has made oil and gas development in the area controversial. The Alaska OCS Region within the Department of the Interior's Minerals Management Service (MMS) oversees oil and gas development in this offshore area. GAO was asked to examine issues related to oil and gas development in the North Aleutian Basin. This report (1) describes the basin's estimated quantities of oil and gas and needed infrastructure; (2) identifies steps MMS is to take to meet federal requirements for oil and gas development; and (3) identifies challenges, if any, MMS faces in meeting these requirements in its Alaska OCS Region. GAO analyzed laws and documents and interviewed representatives from MMS, other federal agencies, state agencies, industry, and other stakeholders."

Capital Purchase Program: Revenues Have Exceeded Investments, but Concerns about Outstanding Investments Remain

A letter report issued by the Government Accountability Office with an abstract that begins "While repayments, dividends, and interest from institutions participating in the Capital Purchase Program (CPP) have exceeded the program’s original investment disbursements, the number of missed payments has increased over the life of the program. As of January 31, 2012, the Department of the Treasury (Treasury) had received $211.5 billion from its CPP investments, exceeding the $204.9 billion it had disbursed. Of that amount, $16.7 billion remains outstanding, and most of these investments were concentrated in a relatively small number of institutions. In particular, as of January 31, 2012, 25 institutions accounted for $11.2 billion, or 67 percent, of outstanding investments. As of November 30, 2011, Treasury estimated that CPP would have a lifetime income of $13.5 billion after all institutions exited the program. As of January 31, 2012, 341 institutions had exited CPP, almost half by repaying CPP with funds from other federal programs. Institutions continue to exit CPP, but the number of institutions missing scheduled dividend or interest payments has increased. For example, as of November 30, 2011, the number of institutions that had missed their quarterly payments rose to 158, a marked increase from …

Higher Education: Issues Related to Law School Accreditation (open access)

Higher Education: Issues Related to Law School Accreditation

A letter report issued by the Government Accountability Office with an abstract that begins "In order to participate in certain federal programs, such as federal student financial aid, postsecondary institutions must be accredited by an accrediting agency recognized by the Department of Education (Education). Accreditation ensures that schools provide basic levels of quality in their educational programs, and Education recognizes those agencies it concludes can reliably determine the quality of education provided by the schools and programs they accredit. Since 1952, Education has recognized the American Bar Association (ABA) as an accrediting agency for law schools. ABA accreditation is important to the 195 law schools it accredits because it allows their graduates the flexibility to take the Bar exam in any jurisdiction in the United States. The Department of Education requires that all recognized accrediting agencies periodically reapply for continued recognition. The Secretary of Education's accreditation advisory group, the National Advisory Committee on Institutional Quality and Integrity (NACIQI), considered the ABA's most recent application for continued recognition in December 2006. The ABA was originally scheduled for review in December 2005, but Education postponed it twice based on the large volume of public comments that had to be reviewed, as well …

Intercollegiate Athletics: Four-Year Colleges' Experiences Adding and Discontinuing Teams (open access)

Intercollegiate Athletics: Four-Year Colleges' Experiences Adding and Discontinuing Teams

A letter report issued by the General Accounting Office with an abstract that begins "The number of women participating in intercollegiate athletics at four-year colleges and universities increased substantially between school years 1981-82 and 1998-99, while the number of men participating increased more modestly. The total number of women's teams increased by 3,784 teams, compared to an increase of 36 men's teams. In all, 963 schools added teams and 307 discontinued teams since 1992-93. The two factors cited most often as greatly influencing the decision to add or discontinue teams were the need to address student interest in particular sports and the need to meet gender equity goals and requirements. Schools that discontinued men's teams also found the need to reallocate the athletic budget to other sports. Colleges and universities that discontinued a team typically took three months or less between originating the proposal and making the final decision. Most schools informed members of the campus community of the possibility that the team would be discontinued, and most held meetings with campus groups before making the final decision. Most schools offered to help affected athletes transfer to other schools, and students receiving athletics-related financial aid continued to receive financial aid …

Farm Credit Administration: Oversight of Special Mission to Serve Young, Beginning, and Small Farmers Needs to Be Improved

A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the Farm Credit Administration's (FCA) regulation of the Farm Credit System (System) to ensure compliance with its statutory mission to serve young, beginning, and small farmers (YBS). FCA has issued YBS-related policies and guidance, designed and implemented a YBS examination protocol, and examined institutions for compliance with YBS requirements. However, FCA has not promulgated regulations to define standards and clarify what constitutes an acceptable YBS program. GAO also found that FCA failed to follow examination procedures and document examination conclusions in the YBS program. Slightly more than half of the institutions in the System had a YBS program or service in place. Nearly one third had set numerical goals for YBS service, although most were not conducting demographic studies. Half had YBS marketing and outreach efforts in place, and most were coordinating their YBS offerings with federal, state, or other governmental or private credit sources."

Military Personnel: Actions Needed to Achieve Greater Results From Air Force Family Need Assessments

A letter report issued by the General Accounting Office with an abstract that begins "To help military families adapt and function effectively in military life, the Department of Defense (DOD) funds a wide variety of personnel and family support programs. These programs use a combination of direct assistance and information and referral to help with crises, deployments, moves, child care, personal financial management, parenting, and transition out of the service. To efficiently distribute funds to those with the greatest need, DOD requires each service to assess the needs of military personnel and their families and their use of family support programs. This report examines (1) how the Air Force determines the needs of its military families, (2) what type of information about military family needs the Air Force obtains, and (3) how information from needs assessments affects the allocation of funding for Air Force family support programs. GAO found that the Air Force assesses the needs of its personnel every two years using a random sample survey. However, the Air Force process does not meet other DOD criteria generally recognized as important for needs assessments, including the use of benchmarks to determine if needs have changed or emerged.

Cigarette Taxes to Fund Health Care Reform: An Economic Analysis (open access)

Cigarette Taxes to Fund Health Care Reform: An Economic Analysis

A cigarette excise tax increase of 75 cents per pack has been proposed to finance part of the President's universal health care program. The tax enjoys considerable public support, would raise about $11 billion per year, and would be relatively simple to administer because it would increase an existing manufacturer's excise tax. This report discusses these rationales, as well as other effects of and concerns about the tax, organized into topics of market failure as a justification for the tax (i.e., economic efficiency); potential for revenue; equity; and the job loss the tax might cause in tobacco growing regions.

14CO2 INCORPORATION INTO THE NUCLEIC ACIDS OF SYNCHRONOUSLYGROWING CHLORELLA CELLS

A study of the incorporation of {sup 14}CO{sub 2} into cell components of synchronously growing Chlorella pyrenoidosa has shown that DNA is synthesized primarily during the latter stages of the cell cycle prior to cell division. RNA was synthesized at an approximately equal rate during each of the three phases of the cell growth studied. No major differences were noted in the incorporation of {sup 14}CO{sub 2} into the soluble cell components in these long-term incorporation studies.

The Path of Carbon in Photosynthesis (open access)

The Path of Carbon in Photosynthesis

The dark fixation of carbon dioxide by green algae has been investigated and found to be closely related to photosynthesis fixation. By illumination in the absence of carbon dioxide followed by treatment with radioactive carbon dioxide in the dark, the amount fixed has been increased ten to twenty fold. This rate of maximum fixation approaches photosynthesis maximum rates. The majority of the radioactive products formed under these conditions have been identified and isolated and the distribution of labeled carbon determined. From these results a tentative scheme for the mechanism of photosynthesis is set forth.

Synchrotron radiation shielding for SLC alcove electronics (open access)

Synchrotron radiation shielding for SLC alcove electronics

The question has been raised concerning where to put lead shielding to reduce the synchrotron radiation dose to the electronics in the alcoves. Assuming that the alcoves are not near a collimator, the dominant radiation source is synchrotron radiation. Previous calculations indicate that a one-centimeter-thick lead door on the alcove would provide sufficient shielding. It was proposed that a one-half-inch-thick lead door be used (the next available thickness). The door would be roughly 36 square ft and weigh 1150 lbs. The alternative would be to shield the transport line, i.e., the open side of the magnets and the gaps between the magnets. We have done some further calculations concerning the possibilities of shielding the transport lines instead of the alcove. The point of contention in previous discussions is whether synchrotron radiation propagates as a gas down the tunnel or whether it is attenuated rapidly.
