By some accounts, catalysis impacts ≥ 30% of GDP in developed countries [Maxwell, I. E. Nature 394, 325-326 (1998)]. Catalysis is the enabling technology for petroleum production, for control of gaseous emissions from petroleum combustion, and for the production of industrial and consumer chemicals. Future applications of catalysis are potentially even more far reaching. There is an ever-growing need to move the economy from a fossil-fuel energy base to cleaner alternatives. Hydrogen-based combustion systems and fuel cells could play a dominant role, given a plentiful and inexpensive source of hydrogen. Photocatalysis is the most promising clean technology for hydrogen production, relying solely on water and sunlight, but performance enhancements in photocatalysis are needed to make this technology economically competitive. Given the enormously wide spread utilization of catalysts, even incremental performance enhancements would have far-reaching benefits for multiple end-use sectors. In the area of fuel and chemical production, such improvements would translate into vast reductions in energy consumption. At the consumption end, improvements in the catalysts involved would yield tremendous reductions in pollution. In the area of photocatalysis, such efficiency improvements could finally render hydrogen an economically viable fuel. Prerequisite to the non-empirical design and refinement of improved catalysts is the …

A letter report issued by the Government Accountability Office with an abstract that begins "Passenger prescreening--a process that includes matching passengers' identifying information against records extracted from the U.S. government terrorist watch list--is one of several security measures in place to help ensure the safety of commercial flights traveling to or from the United States. DHS has several efforts underway to strengthen international aviation passenger prescreening. This report focuses on certain elements of the passenger prescreening process as well as some of the actions that DHS is taking or has planned to strengthen prescreening procedures. This report is a limited version of the original November 2006 report as various agencies that we reviewed deemed some of the information in the original report to be security sensitive. GAO's work included interviewing officials and assessing relevant documentation from federal agencies, U.S. and foreign air carriers, industry groups, and several foreign countries."

The Very High Temperature gas cooled reactor (VHTR) is one of the GEN IV reactor concepts that have been proposed for thermochemical hydrogen production and other process-heat applications like coal gasification. The USDOE has selected the VHTR for further research and development, aiming to demonstrate emissions-free electricity and hydrogen production at a future time. One of the major safety advantages of the VHTR is the potential for passive decay heat removal by natural circulation of air in a Reactor Cavity Cooling System (RCCS). The air-side of the RCCS is very similar to the Reactor Vessel Auxiliary Cooling System (RVACS) that has been proposed for the PRISM reactor design. The design and safety analysis of the RVACS have been based on extensive analytical and experimental work performed at ANL. The Natural Convective Shutdown Heat Removal Test Facility (NSTF) at ANL that simulates at full scale the air-side of the RVACS was built to provide experimental support for the design and analysis of the PRISM RVACS system. The objective of this work is to demonstrate that the NSTF facility can be used to generate RCCS experimental data: to validate CFD and systems codes for the analysis of the RCCS; and to support …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Transportation's (DOT) Federal Motor Carrier Safety Administration (FMCSA) is responsible for protecting consumers involved in interstate household goods moves by issuing regulations and conducting oversight and enforcement actions. The Safe, Accountable, Flexible, Efficient Transportation Equity Act--A Legacy for Users (SAFETEA-LU), enacted in 2005, included provisions to enhance consumer protections for household goods moves and mandated that GAO study (1) the protections federal laws and regulations provide to consumers of interstate household goods moves and the effectiveness of federal enforcement efforts, (2) the protections states provide to consumers of intrastate household goods moves and how they have affected consumers and movers, and (3) the potential effects on both consumers and interstate movers if movers were subject to state consumer protection laws. To address these issues, GAO analyzed federal and state legislation, federal complaint and enforcement data, and interviewed federal and state officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The 2005 Base Realignment and Closure (BRAC) recommendations affected 62 percent of the flying units in the Air National Guard (ANG) with 14 units losing their flying mission, and others converting from one type of aircraft to another, or increasing or decreasing assigned aircraft. To implement the recommendations, ANG must relocate hundreds of aircraft and retrain or recruit about 15,000 personnel by 2011. In this report, GAO addresses the status of efforts to implement the ANG BRAC actions. GAO's objectives were to determine (1) the process to provide replacement missions to units losing flying missions, (2) the progress and challenges in implementing the BRAC actions, and (3) changes to the cost and savings estimates. This report, prepared under the Comptroller General's authority to conduct evaluations on his own initiative, is one in a series of reports related to 2005 BRAC recommendations. GAO conducted its work at the Air Force, ANG headquarters, and in 11 states affected by BRAC 2005"

A letter report issued by the Government Accountability Office with an abstract that begins "The Mine Safety and Health Administration (MSHA), the National Institute for Occupational Safety and Health (NIOSH), the Federal Mine Safety and Health Review Commission, the Department of Labor's Office of the Solicitor, the states, and the mining industry share responsibility for ensuring mine safety. GAO examined the challenges underground coal mines face in preparing for emergencies, how well MSHA oversees mine operators' training efforts, how well MSHA and NIOSH coordinate to enhance the development and approval of mine safety technology, and how civil penalties are assessed. To address these issues, GAO surveyed a representative sample of active underground coal mines, analyzed agency data, conducted site visits, and talked with agency officials and other experts. The survey results are estimated at the 95 percent confidence level."

Continental margin sediments constitute only about 10% of the total sediment surface area in the world’s oceans, nevertheless they are the dominant sites of nitrogen (N) cycling. Recent studies suggest that the oceanic nitrogen budget is unbalanced, primarily due to a higher nitrogen removal rate in contrast to the fixation rate, and it has been suggested that denitrification activity contributes significantly to this imbalance. Although denitrification in marine environments has been studied intensively at the process level, little is known about the species abundance, composition, distribution, and functional differences of the denitrifying population. Understanding the diversity of microbial populations in marine environments, their responses to various environmental factors such as NO3-, and how this impact the rate of denitrification is critical to predict global N dynamics. Environmental Microbiology has the prompt to study the influence of each microbial population on a biogeochemical process within a given ecosystem. Culture-dependent and –independent techniques using nucleic acid probes can access the identity and activity of cultured and uncultured microorganisms. Nucleic acid probes can target distintict genes which set phylogenetic relationships, such as rDNA 16S, DNA gyrase (gyrB) and RNA polymerase sigma 70 factor (rpoD). In the other hand, the genetic capabilities and their …

A letter report issued by the Government Accountability Office with an abstract that begins "When a nonfederal public entity such as a city or county wants to build a public works project that could degrade or damage federally regulated waters and wetlands, it must obtain a permit from the U.S. Army Corps of Engineers (Corps) before proceeding. To help expedite the permit process for these entities, the Congress enacted section 214 of the Water Resources and Development Act of 2000, providing the Corps with temporary authority to receive funds from such entities and use the funds to process permits. To ensure the impartiality and transparency of section 214 permit decisions, the Corps requires its districts to adhere to all existing permit review processes, as well as some additional requirements. GAO was asked to identify (1) how many districts have used the section 214 authority, (2) the amount of funds they have received, (3) how permit processing times have changed, (4) the extent to which districts have adhered to the existing review processes and the additional requirements."
