Correspondence issued by the Government Accountability Office with an abstract that begins "Federal laws and regulations require that safety-related transportation professionals undergo screening to ensure that they can safely perform their jobs. Medical certification and background checks of selected pilots, vessel masters, and commercial drivers are part of the requirements for licensing these workers. Certification or licensing also includes testing workers' knowledge and skills required for the jobs. These checks are critical because physically or mentally unfit transportation workers pose a danger to themselves and to the public. Because of concerns raised by recent investigations of the reliability of pilot medical certifications, Congress asked us to first describe the requirements for medical and background checks for selected transportation workers. Accordingly, we addressed the following questions for (1) medical certification and (2) background checks: What are the regulations governing pilots, vessel masters, and commercial drivers and what role do government entities have in completing the certifications and background checks? A second report, which will be issued mid-2008, will provide information about the steps that the Federal Aviation Administration (FAA) takes to check the accuracy of pilot medical certificates. Federal regulations require that pilots have both pilot certificates and medical certificates prior …

A letter report issued by the Government Accountability Office with an abstract that begins "Using lessons from the 2005 Gulf Coast hurricanes, the federal government released the National Response Framework (NRF) in January 2008. This report examines (1) why the primary role for mass care in the NRF shifted from the Red Cross to the Federal Emergency Management Agency (FEMA), and potential issues with implementation, (2) whether National Voluntary Organizations Active in Disasters (NVOAD)--an umbrella organization of 49 voluntary agencies--is equipped to fulfill its NRF role, (3) the extent to which FEMA has addressed issues with mass care for the disabled since the hurricanes, (4) the extent to which major voluntary agencies have prepared to better serve the disabled since the hurricanes, and (5) the extent to which FEMA has addressed issues voluntary agencies faced in receiving Public Assistance reimbursement. To analyze these issues, GAO reviewed the NRF and other documents, and interviewed officials from FEMA, voluntary agencies, and state and local governments."

Testimony issued by the Government Accountability Office with an abstract that begins "A growing portion of federal spending is related to buying services such as administrative, management, and information technology support. Services accounted for about 60 percent of total fiscal year 2006 procurement dollars. The Services Acquisition Reform Act (SARA) of 2003 established an Acquisition Advisory Panel to make recommendations for improving acquisition practices. In January 2007, the panel proposed 89 recommendations to improve federal acquisition practices. GAO was asked to testify on how the panel recommendations compare to GAO's past work and identify how the Office of Federal Procurement Policy (OFPP) expects the recommendations to be addressed. This statement is based on GAO's analysis of the advisory panel's report. GAO's analysis is included in its December 2007 report titled, Federal Acquisition: Oversight Plan Needed to Help Implement Acquisition Advisory Panel Recommendation, (GAO-08-160)."

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Patent and Trademark Office (USPTO) helps protect U.S. competitiveness by granting patents for new ideas and innovations. Increases in the volume and complexity of patent applications have extended the time for processing them. Concerns continue about the agency's efforts to attract and retain qualified patent examiners who can meet the demand for patents and help reduce the growing backlog of unexamined patent applications. In 2007, GAO reported on (1) USPTO's process for making its annual hiring estimates and the relationship of these estimates to the patent application backlog; (2) the extent to which patent examiner hiring has been offset by attrition, and the factors that may contribute to this attrition; and (3) the extent to which USPTO's retention efforts align with examiners' reasons for staying with the agency. GAO recommended that USPTO comprehensively evaluate the assumptions it uses to establish its production goals. USPTO agreed to implement this recommendation once it determines the effect of recent initiatives designed to increase the productivity of the agency through a more efficient and focused patent examination process. This testimony is based on GAO's 2007 report, which was based in …

Testimony issued by the Government Accountability Office with an abstract that begins "In February 2007, a series of Washington Post articles about conditions at Walter Reed Army Medical Center highlighted problems in the Army's case management of injured servicemembers and in the military's disability evaluation system. These deficiencies included a confusing disability evaluation process and servicemembers in outpatient status for months and sometimes years without a clear understanding about their plan of care. These reported problems prompted various reviews and commissions to examine the care and services to servicemembers. In response to problems at Walter Reed and subsequent recommendations, the Army took a number of actions and DOD formed a joint DOD-VA Senior Oversight Committee. This statement updates GAO's September 2007 testimony and is based on ongoing work to (1) assess actions taken by the Army to help ill and injured soldiers obtain health care and navigate its disability evaluation process; and to (2) describe the status, plans, and challenges of DOD and VA efforts to implement a joint disability evaluation system. GAO's observations are based largely on documents obtained from and interviews with Army, DOD, and VA officials. The facts contained in this statement were discussed with representatives from …

Testimony issued by the Government Accountability Office with an abstract that begins "In November 2005, the Department of Homeland Security (DHS) established the Secure Border Initiative (SBI), a multiyear, multibillion-dollar program to secure U.S. borders. One element of SBI is the U.S. Customs and Border Protection's (CBP) SBI program, which is responsible for developing a comprehensive border protection system through a mix of security infrastructure (e.g., fencing) and surveillance and communication technologies (e.g., radars, sensors, cameras, and satellite phones). GAO was asked to monitor DHS progress in implementing CBP's SBI program. This testimony provides GAO's observations on (1) technology implementation; (2) the extent to which Border Patrol agents have been trained and are using SBI technology; (3) infrastructure implementation; and (4) how the CBP SBI program office has defined its human capital goals and the progress it has made to achieve these goals. GAO's observations are based on analysis of DHS documentation, such as program schedules, contracts, status, and reports. GAO also conducted interviews with DHS officials and contractors, and visits to sites in the southwest border where SBI deployment is under way. GAO performed the work from November 2007 through February 2008. DHS generally agreed with GAO's findings."

The Savannah River National Laboratory measured the hydraulic conductivity of peat samples using method ASTM D4511-00. Four samples of peat were packed into 73mm diameter plastic tubes and saturated from the bottom up with water. The columns were packed with Premier ProMoss III TBK peat to a dry density of approximately 0.16 gm/cc (10 lb/ft3). One column was packed using oven dried peat and the other 3 were packed using as delivered peat. The oven dried sample was the most difficult to saturate. All of the peat samples expanded during saturation resulting in a sample length (L) that was longer than when the sample was initially packed. Table 1 contains information related to the column packing. After saturation the hydraulic conductivity test was conducted using the apparatus shown in Figure 1. Three of the samples were tested at 2 different flow conductions, 1 high and 1 low. Table 2 and Figure 2 contain the results of the hydraulic conductivity testing. Each test was run for a minimum of 40 minutes to allow the test conditions to stabilize. The hydraulic conductivity at the end of each test is reported as the hydraulic conductivity for that test. The hydraulic conductivity of the …

The authors present the design and first results of a low-temperature, ultrahigh vacuum scanning probe microscope enabling atomic resolution imaging in both scanning tunneling microscopy (STM) and noncontact atomic force microscopy (NC-AFM) modes. A tuning-fork-based sensor provides flexibility in selecting probe tip materials, which can be either metallic or nonmetallic. When choosing a conducting tip and sample, simultaneous STM/NC-AFM data acquisition is possible. Noticeable characteristics that distinguish this setup from similar systems providing simultaneous STM/NC-AFM capabilities are its combination of relative compactness (on-top bath cryostat needs no pit), in situ exchange of tip and sample at low temperatures, short turnaround times, modest helium consumption, and unrestricted access from dedicated flanges. The latter permits not only the optical surveillance of the tip during approach but also the direct deposition of molecules or atoms on either tip or sample while they remain cold. Atomic corrugations as low as 1 pm could successfully be resolved. In addition, lateral drifts rates of below 15 pm/h allow long-term data acquisition series and the recording of site-specific spectroscopy maps. Results obtained on Cu(111) and graphite illustrate the microscope's performance.

The Savannah River Site (SRS) has 49 underground storage tanks used to store High Level Waste (HLW). The tank space in these tanks must be managed to support the continued operation of key facilities. The reduction of the tank volumes in these tanks are accomplished through the use of three atmospheric pressure HLW evaporators. For a decade, evaporation of highly alkaline HLW containing aluminum and silicates has produced sodium aluminosilicate scales causing both operation and criticality hazards in the 2H Evaporator System. Segregation of aluminum-rich wastes from silicate-rich wastes minimizes the amount of scale produced and reduces cleaning expenses, but does not eliminate the scaling nor increases operation flexibility in waste process. Similar issues have affected the aluminum refining industry for many decades. Over the past several years, successful commercial products have been identified to eliminate aluminosilicate fouling in the aluminum industry, but have not been utilized in a nuclear environment. Laboratory quantities of three proprietary aluminosilicate scale inhibitors have been produced and been shown to prevent formation of scales. SRNL has been actively testing these potential inhibitors to examine their radiation stability, radiolytic degradation behaviors, and downstream impacts to determine their viability within the HLW system. One of the …

Down the drain: Cryptophane cages in combination with selective radiofrequency spin labeling can be used as molecular 'transpletor' units for transferring depletion of spin polarization from a hyperpolarized 'source' spin ensemble to a 'drain' ensemble. The flow of nuclei through the gate is adjustable by the ambient temperature, thereby enabling controlled consumption of hyperpolarization.

During the contract period noted above, the Syracuse University Industrial Assessment Center conducted 97.5 assessment days for 98 different industrial clients. These assessments developed 818 assessment recommendations with an overall implementation rate of 51 % (AR’s). Total recommended dollar savings for the period was $17,386,758.00, with $8,893,212.00 actually implemented, for a dollar implementation rate of 57%. The Center employed a total of sixteen undergraduate interns throughout the contract period. Nine of these students stayed on at Syracuse University for graduate study with Center support; five students pursued graduate study at other universities. Ten of these students have, or will, accept professional positions in the energy consulting field. The Center has successfully engaged with a wide variety of professional and development organizations, including the Manufacturers Association of Central New York, The Central New York Technical Development Organization, (the local MEP), the New York State Energy Research and Development Authority, The New York Power Authority, the Onondaga County Citizens Energy Committee, and the New York State Center of Excellence on Indoor Environmental Systems.

This report provides the results of detailed hydrologic characterization tests conducted within selected Hanford Site wells during fiscal and calendar year 2005. Detailed characterization tests performed included groundwater-flow characterization, barometric response evaluation, slug tests, in-well vertical groundwater-flow assessments, and a single-well tracer and constant-rate pumping test. Hydraulic property estimates obtained from the detailed hydrologic tests include hydraulic conductivity, transmissivity, specific yield, effective porosity, in-well lateral and vertical groundwater-flow velocity, aquifer groundwater-flow velocity, and depth-distribution profiles of hydraulic conductivity. In addition, local groundwater-flow characteristics (i.e., hydraulic gradient and flow direction) were determined for a site where detailed well testing was performed. Results obtained from these tests provide hydrologic information that supports the needs of Resource Conservation and Recovery Act waste management area characterization as well as sitewide groundwater monitoring and modeling programs. These results also reduce the uncertainty of groundwater-flow conditions at selected locations on the Hanford Site.

This report examines the importance to the U.S. economy of China's investment in U.S. securities, as well as U.S. concerns over the possibility that China might unload a large share of those holdings, including the likelihood that this would occur, and the potential implications such action could have for the U.S. economy. The report concludes that a large sell-off of Chinese Treasury securities holdings could negatively affect the U.S. economy, at least in the short-run. As a result, such a move could diminish U.S. demand for Chinese products and thus could lower China's economic growth as well.
