Air Quality: EPA’s 2006 Changes to the Particulate Matter (PM) Standard (open access)

Air Quality: EPA’s 2006 Changes to the Particulate Matter (PM) Standard

In order to better understand EPA’s actions, this report provides an analysis of the agency’s final 2006 revisions to the particulates NAAQS, and the estimated costs and benefits of the new standards and of a more stringent alternatives analyzed. The report concludes by highlighting concerns and issues raised regarding the revisions to the particulates standards, including those of the science advisory committee (Clean Air Scientific Advisory Committee, or CASAC), and actions in Congress.

Air Quality Issues and Animal Agriculture: A Primer (open access)

Air Quality Issues and Animal Agriculture: A Primer

This report reviews the types of air emissions from livestock and poultry operations and their human health and environmental impacts. It then discusses provisions of several federal laws concerned with environmental impacts, beginning with the Clean Water Act, because protecting water resources has been the primary regulatory focus regarding livestock and animal operations.

Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement

This report discusses a plan announced by EPA in January 2005, called the Air Compliance Agreement, that would produce air quality monitoring data on animal agriculture emissions from a small number of farms, while at the same time protecting all participants (including farms where no monitoring takes place) through a “safe harbor” from liability under certain provisions of federal environmental laws.

APPLICATION OF NONSPHERICAL FISSILE CONFIGURATION IN WASTE CONTAINERS AT SRS (open access)

APPLICATION OF NONSPHERICAL FISSILE CONFIGURATION IN WASTE CONTAINERS AT SRS

Transuranic (TRU) solid waste that has been generated as a result of the production of nuclear material for the United States defense program at the Savannah River Site (SRS) has been stored in more than 30,000 55-gallon drums and carbon steel boxes since 1953. Nearly two thirds of those containers have been processed and shipped to the Waste Isolation Pilot Plant. Among the containers assayed so far, the results indicate several drums with fissile inventories significantly higher (600-1000 fissile grams equivalent (FGE) {sup 239}Pu) than their original assigned values. While part of this discrepancy can be attributed to the past limited assay capabilities, human errors are believed to be the primary contributor. This paper summarizes the application of nonspherical fissile material configuration in waste containers, resulting in less restrictive mass and spacing limits, increased storage capacity, and several administrative controls for handling and storage of waste containers being modified without compromising safety.

APTASENSORS FOR BIOSECURITY APPLICATIONS (open access)

APTASENSORS FOR BIOSECURITY APPLICATIONS

Nucleic acid aptamers have found steadily increased utility and application steadily over the last decade. In particular, aptamers have been touted as a valuable complement to and in some cases replacement for antibodies due to their structural and functional robustness as well as their ease in generation and synthesis. They are thus attractive for biosecurity applications, e.g. pathogen detection, and are especially well suited since their in vitro generation process does not require infection of any host systems. Herein we provide a brief overview of the aptamers generated against biopathogens over the last few years. In addition, a few recently described detection platforms using aptamers (aptasensors) and potentially suitable for biosecurity applications will be discussed.

Biogenic UO_2 _ Characterization and Surface Reactivity (open access)

Biogenic UO_2 _ Characterization and Surface Reactivity

Nano-scale biogenic UO{sub 2} is easier to oxidize and more reactive to aqueous metal ions than bulk UO{sub 2}. In an attempt to understand these differences in properties, we have used a suite of bulk and surface characterization techniques to examine differences in the reactivity of biogenic UO{sub 2} versus bulk UO{sub 2} with respect to aqueous Zn(II). Precipitation of biogenic UO{sub 2} was mediated by Shewanella putrefaciens CN32, and the precipitates were washed using two protocols: (1) 5% NaOH, followed by 4 mM KHCO{sub 3}/KCl (NA-wash; ''NAUO2'', to remove surface organic matter), and (2) 4 mM KHCO{sub 3}-KCl (BI-wash; ''BIUO2'', to remove soluble uranyl species). BET surface areas of biogenic-UO{sub 2} prepared using the two protocols are 128.63 m{sup 2}g{sup -1} and 92.56 m{sup 2}g{sup -1}, respectively; particle sizes range from 2-10 nm as determined by FEG-SEM. Surface composition was probed using XPS, which showed a strong carbon 1s signal for the BI-washed samples; surface uranium is > 90% U(IV) for both washing protocols. U L{sub III}-edge XANES spectra also indicate that U(IV) is the dominant oxidation state in the biogenic UO{sub 2} samples. Fits of the EXAFS spectra of these samples yielded half the number of uranium second-shell …

Branching Fraction Measurements of B+ to rho+ gamma,B0 to rho0 gamma, and B0 to omega gamma (open access)

Branching Fraction Measurements of B+ to rho+ gamma,B0 to rho0 gamma, and B0 to omega gamma

The authors present a study of the decays B{sup +} {yields} {rho}{sup +}{gamma}, B{sup 0} {yields} {rho}{sup 0}{gamma}, and B{sup 0} {yields} {omega}{gamma}. The analysis is based on data containing 347 million B{bar B} events recorded with the BABAR detector at the PEP-II asymmetric B factory. They measure the branching fractions {Beta}(B{sup +} {yields} {rho}{sup +}{gamma}) = (1.10{sub -0.33}{sup +0.37} {+-} 0.09) x 10{sup -6} and {Beta}(B{sup 0} {yields} {rho}{sup 0}{gamma}) = (0.79{sub -0.20}{sup +0.22} {+-} 0.06) x 10{sup -6}, and set a 90% C.L. upper limit {Beta}(B{sup 0} {yields} {omega}{gamma}) < 0.78 x 10{sup -6}. They also measure the isospin-averaged branching fraction {Beta}[B {yields} ({rho}/{omega}){gamma}] = (1.25{sub -0.24}{sup +0.25} {+-} 0.09) x 10{sup -6}, from which they determine |V{sub td}/V{sub ts}| = 0.200{sub -0.020}{sup +0.021} {+-} 0.015, where the first uncertainty is experimental and the second is theoretical.

Computational Proteomics: High-throughput Analysis for Systems Biology (open access)

Computational Proteomics: High-throughput Analysis for Systems Biology

High-throughput (HTP) proteomics is a rapidly developing field that offers the global profiling of proteins from a biological system. The HTP technological advances are fueling a revolution in biology, enabling analyses at the scales of entire systems (e.g., whole cells, tumors, or environmental communities). However, simply identifying the proteins in a cell is insufficient for understanding the underlying complexity and operating mechanisms of the overall system. Systems level investigations are relying more and more on computational analyses, especially in the field of proteomics generating large-scale global data.
