A letter report issued by the Government Accountability Office with an abstract that begins "Computer networks and infrastructures, on which the United States and much of the world rely to communicate and conduct business, contain vulnerabilities that can leave them susceptible to unauthorized access, disruption, or attack. Investing in research and development (R&D) is essential to protect critical systems and to enhance the cybersecurity of both the government and the private sector. Federal law has called for improvements in cybersecurity R&D, and, recently, President Obama has stated that advancing R&D is one of his administration's top priorities for improving cybersecurity. GAO was asked to determine the key challenges in enhancing national-level cybersecurity R&D efforts among the federal government and private companies. To do this, GAO consulted with officials from relevant federal agencies and experts from private sector companies and academic institutions as well as analyzed key documents, such as agencies' research plans."

In 1993, after many months of study, debate, and political controversy, Congress passed and President Clinton signed legislation establishing a revised "[p]olicy concerning homosexuality in the armed forces." The new legislation reflected a compromise regarding the U.S. military's policy toward members of the armed forces who engage in homosexual conduct. This compromise, colloquially referred to as "Don't Ask, Don't Tell (DADT)," holds that "[t]he presence in the armed forces of persons who demonstrate a propensity or intent to engage in homosexual acts would create an unacceptable risk to the high standards of morale, good order and discipline, and unit cohesion which are the essence of military capability." Service members are not to be asked about, nor allowed to discuss, their sexual orientation. This compromise notwithstanding, the issue has remained both politically and legally contentious. This report provides a legal analysis of the various constitutional challenges that have been brought against DADT.

This report is an evaluation of Best Available Control Technology for Toxics (tBACT) for installation and operation of the Hanford double shell (DST) tank primary ventilation systems. The DST primary ventilation systems are being modified to support Hanford's waste retrieval, mixing, and delivery of single shell tank (SST) and DST waste throught the DST storage system to the Waste Treatment and Immobilization Plant (WTP).

This report summarizes the FY2011 budget request for research & development (R&D) funding, including comparisons to R&D funding requests in the FY2010 budget. Congress will play a central role in defining the nation's R&D priorities, especially with respect to two overarching issues: the extent to which the Federal R&D investment can grow in the context of increased pressure on discretionary spending and how available funding will be prioritized and allocated. This report breaks down in detail the various aspects of the President's FY2011 R&D funding request.

The 105-R Reactor Disassembly Basin Grout Placement Strategy Report (SRNL-TR-2009-00157) identifies various portions of the facility that will undergo an in-situ decommissioning process. The estimated residual radioactive contamination in the 105-R facility is shown in Figure 1. Cementitious grout formulations developed by SRNL are being used to immobilize and isolate the radioactive contamination in existing below grade portions of the 105-R building as shown by the gray-hatched area in Figure 2. A Zero Bleed flowable fill was formulated for both dry placement and for underwater placement. The first major area in the 105-R Disassembly Basin to undergo the grouting process was the D&E Canal and an underlying void space known as the Chase. Grout temperature data was needed to ensure that the grout mix design was on the correct grout curing trajectory to meet the material compressive strength requirement of 50 pounds per square inch. Initial grout temperature measurements were needed to confirm and optimize grout mix design fresh property characteristics; i.e. material strength, and set time. Grout curing temperature is an integrating fresh property characteristic that is used to estimate cementitious material strength in accordance with the Standard Practice for Estimating Concrete Strength by the Maturity Method, ASTM C …

Our research group has been engaged in the past few years in the synthesis of biphenol based partially disulfonated poly(arylene ether sulfone) random copolymers as potential PEMs. This series of polymers are named as BPSH-xx, where BP stands for biphenol, S stands for sulfonated, H stands for acidified and xx represents the degree of disulfonation. All of these sulfonated copolymers phase separate to form nano scale hydrophilic and hydrophobic morphological domains. The hydrophilic phase containing the sulfonic acid moieties causes the copolymer to absorb water. Water confined in hydrophilic pores in concert with the sulfonic acid groups serve the critical function of proton (ion) conduction and water transport in these systems. Both Nafion and BPSH show high proton conductivity at fully hydrated conditions. However proton transport is especially limited at low hydration level for the BPSH random copolymer. It has been observed that the diffusion coefficients of both water and protons change with the water content of the pore. This change in proton and water transport mechanisms with hydration level has been attributed to the solvation of the acid groups and the amount of bound and bulk-like water within a pore. At low hydration levels most of the water is …

This report covers the North American Free Trade Agreement (NAFTA), and U.S. - Mexico drug trafficking. It also looks at migration, environmental issues, legislation in the 111th, and the relationship between the Obama Administration and Mexico.

This report provides an overview of Mexico's motivations for entering the North American Free Trade Agreement (NAFTA), the Mexican economy, the economic effects of NAFTA in Mexico, and the views of NAFTA within Mexico. It also provides information on NAFTA's effect on Mexico's agricultural sector because this has been one of the more controversial issues surrounding NAFTA in Mexico.
