Under the auspices of this funding, we have developed a program to synthesize and characterize highly monodispersed magnetic nanoparticles. We have been particularly interested in the origin of the exchange bias effect, which occurs in compound nanoparticles with a ferromagnetic core and an antiferromagnetic shell, and have mostly focused on Co/CoO core-shell nanoparticles. The exchange bias effect involves exchange coupling between the core moment and the antiferromagnetic shell which stabilizes the core moment, which would otherwise be quickly reorienting in ferromagnetic particles of this size.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Commerce's (Commerce) U.S. Census Bureau (Bureau) seeks updated information on the addresses and maps of housing units and group quarters from state, local, and tribal governments through the Local Update of Census Addresses (LUCA) Program. Prepared under the Comptroller General's authority, this report assesses (1) the status of the LUCA Program, (2) the Bureau's response to prior recommendations by GAO and others and new challenges related to the program, and (3) the Bureau's plans for conducting the program in areas affected by hurricanes Katrina and Rita. GAO reviewed LUCA program documents, met with and surveyed participants in the LUCA Dress Rehearsal, and interviewed Bureau officials and local officials in the Gulf Coast region."

We numerically construct black hole solutions corresponding to the deconfined, chirally symmetric phase of strongly coupled cascading gauge theories at various temperatures. We compute the free energy as a function of the temperature, and we show that it becomes positive below some critical temperature, indicating the possibility of a first order phase transition at which the theory deconfines and restores the chiral symmetry.

A letter report issued by the Government Accountability Office with an abstract that begins "The Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) protects the rights of military personnel, their dependents, and overseas citizens to vote by absentee ballot. The Department of Defense (DOD) and others have reported that absentee voting, which relies primarily on mail, can be slow and may, in certain circumstances, serve to disenfranchise these voters. In 2004, Congress required DOD to develop an Internet-based absentee voting demonstration project and required the Election Assistance Commission--which reviews election procedures--to develop guidelines for DOD's project. In 2006, Congress required DOD to report, by May 15, 2007, on plans for expanding its use of electronic voting technologies and required GAO to assess efforts by (1) DOD to facilitate electronic absentee voting and (2) the Commission to develop Internet voting guidelines and DOD to develop an Internet-based demonstration project. GAO also assessed DOD's efforts to develop plans to expand its use of electronic voting technologies. GAO interviewed officials and reviewed and analyzed documents related to these efforts."

Due to their excellent corrosion resistance, iron aluminum alloys are currently being considered for use as weld claddings in fossil fuel fired power plants. The susceptibility to hydrogen cracking of these alloys at higher aluminum concentrations has highlighted the need for research into the effect of chromium additions on the corrosion resistance of lower aluminum alloys. In the present work, three iron aluminum alloys were exposed to simulated coal combustion environments at 500 C and 700 C for both short (100 hours) and long (5,000 hours) isothermal durations. Scanning electron microscopy was used to analyze the corrosion products. All alloys exhibited excellent corrosion resistance in the short term tests. For longer exposures, increasing the aluminum concentration was beneficial to the corrosion resistance. The addition of chromium to the binary iron aluminum alloy prevented the formation iron sulfide and resulted in lower corrosion kinetics. A classification of the corrosion products that developed on these alloys is presented. Scanning transmission electron microscopy (STEM) of the as-corroded coupons revealed that chromium was able to form chromium sulfides only on the higher aluminum alloy, thereby preventing the formation of deleterious iron sulfides. When the aluminum concentration was too low to permit selective oxidation of …

Laboratory management requires that the controls specified in this Facility Safety Plan (FSP) be applied to efficiently and safely perform operations within these facilities. Any operation conducted in these facilities that involves activities not commonly performed by the public, requires an Integrated Work Sheet to determine the appropriate level of safety documentation.

A saltstone waste form was prepared in the Savannah River National Laboratory from a Tank 50H sample and Z-Area premix material. After the prescribed 28 day cure, samples of the saltstone were collected, and the waste form was shown to meet the South Carolina Hazardous Waste Management Regulations (SCHWMR) R.61-79.261.24 requirements for a nonhazardous waste form with respect to RCRA metals. These analyses met all quality assurance specifications of USEPA SW-846.

A letter report issued by the Government Accountability Office with an abstract that begins "Changes to the U.S. economy have led to longer-term unemployment. Many unemployed workers receive Unemployment Insurance (UI), which provided about $30 billion in benefits in 2006. In 1993, Congress established requirements--now known as the Worker Profiling and Reemployment Services (WPRS) initiative--for state UI agencies to identify claimants who are most likely to exhaust their benefits, and then refer such claimants to reemployment services. To assess the implementation and effect of the initiative, GAO examined (1) how states identify claimants who are most likely to exhaust benefits, (2) to what extent states provide reemployment services as recommended by the Department of Labor (Labor), and (3) what is known about the effectiveness of the initiative in accelerating reemployment. To answer these questions, we used a combination of national data; review of seven states, including visits to local service providers in four states; and existing studies and interviews with Labor and subject matter experts."

A letter report issued by the Government Accountability Office with an abstract that begins "Increasing retirements and declining fertility rates, among other factors, could affect the labor force growth in many developed countries. To maintain the size and productivity of the labor force, many governments and employers have introduced strategies to keep workers, such as women and low-skilled workers, in the workforce throughout their working lives. Because other countries have also undertaken efforts to address issues similar to those occurring in the U.S., GAO was asked to (1) describe the policies and practices implemented in other developed countries that may help women and low-wage/low-skilled workers enter and remain in the labor force; (2) examine the targeted groups' employment following the implementation of the policies and practices; and (3) identify the factors that affect employees' use of workplace benefits and the resulting implications. We conducted an extensive review of workplace flexibility and training strategies in a range of developed countries, and we conducted site visits to selected countries. Our reviews were limited to materials that were available in English. While we identified relevant national policies in the U.S., we did not determine whether other countries' strategies could be implemented here. Labor …

This report discusses broadband Internet, examining what it is and the various technologies that allow for its transmission. Broadband or high-speed Internet access is provided by technologies that give users the ability to send and receive data at volumes and speeds far greater than access over traditional telephone lines; it also provides a continuous, "always on" connection (no need to dial-up) and a "twoway" capability, that is, the ability to both receive (download) and transmit (upload) data at high speeds.

The Legislative Reference Service, it was charged with responding to congressional requests for information. For more than 50 years, this department assisted Congress primarily by providing facts and publications and by transmitting research and analysis done largely by other government agencies, private organizations, and individual scholars. In 1970, Congress enacted a law transforming the Legislative Reference Service into the Congressional Research Service (CRS) and directing CRS to devote more of its efforts and increased resources to performing research and analysis that assists Congress in direct support of the legislative process.

With the passing of FY2006 supplemental bill H.R. 4939, Congress will have appropriated a total of about $437 billion for the three military operations initiated since the 9/11 attacks: Operation Enduring Freedom (OEF) covering Afghanistan and other Global War on Terror (GWOT) operations, Operation Noble Eagle (ONE) providing enhanced security at military bases, and Operation Iraqi Freedom (OIF), Iraq. On a monthly basis, the Department of Defense (DOD) spent an average of about $6.4 billion for OIF, $1.3 billion for OEF, and $180 million for enhanced base security in FY2005. Potential oversight issues for Congress include getting estimates of the cost to repair and replae war-worn equipment and of possible offsetting costs to DOD's regular budget because equipment is being fixed or bought earlier than planned. DOD's annual war funding may reach $118 billion in FY2006 if the pending supplemental is enacted.
