Congressional Oversight: FAA Case Study Shows How Agency Performance, Budgeting, and Financial Information Could Enhance Oversight

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Pursuant to various statutes, federal agencies develop an abundance of performance, budget, and financial information that could be useful for Congress' review and monitoring of agencies. However, agencies' understanding of Congress' information needs is often limited and agencies may not be providing timely information in a format that aids congressional understanding of trends and issues. Thus, Member… more

Defense Logistics: More Efficient Use of Active RFID Tags Could Potentially Avoid Millions in Unnecessary Purchases

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "For many years, the Department of Defense (DOD) has been attempting to improve visibility over its inventory and equipment. The lack of visibility over inventory and equipment shipments increases vulnerability to undetected loss or theft and substantially heightens the risk that millions of dollars will be spent unnecessarily. Additionally, needed supplies may not reach the warfighter when needed, which … more

Paperwork Reduction Act: New Approaches Can Strengthen Information Collection and Reduce Burden

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Americans spend billions of hours each year providing information to federal agencies by filling out forms, surveys, or questionnaires. A major aim of the Paperwork Reduction Act (PRA) is to minimize the burden that these information collections impose on the public, while maximizing their public benefit. Under the act, the Office of Management and Budget (OMB) is to approve all such collections. In addition,… more

Numerical Modeling of CO2 Sequestration in Geologic Formations - Recent Results and Open Challenges

Description: Rising atmospheric concentrations of CO2, and their role inglobal warming, have prompted efforts to reduce emissions of CO2 fromburning of fossil fuels. An attractive mitigation option underconsideration in many countries is the injection of CO2 from stationarysources, such as fossil-fueled power plants, into deep, stable geologicformations, where it would be stored and kept out of the atmosphere fortime periods of hundreds to thousands of years or more. Potentialgeologic storage reservoirs inc… more

Some Results Bearing on the Value of Improvements of Membranes for Reverse Osmosis

Description: This analysis evaluates the potential economic benefits that could result from the improvements in the permeability of membranes for reverse osmosis. The discussion provides a simple model of the operation of a reverse osmosis plant. It examines the change in the operation that might result from improvements in the membrane and computes the cost of water as a function of the membrane permeability.

Intensity-based signal separation algorithm for accuratequantification of clustered centrosomes in tissue sections

Description: Centrosomes are small organelles that organize the mitoticspindle during cell division and are also involved in cell shape andpolarity. Within epithelial tumors, such as breast cancer, and somehematological tumors, centrosome abnormalities (CA) are common, occurearly in disease etiology, and correlate with chromosomal instability anddisease stage. In situ quantification of CA by optical microscopy ishampered by overlap and clustering of these organelles, which appear asfocal structures. CA has … more

Cryogenic Neutron Spectrometer Development

Description: Cryogenic microcalorimeter detectors operating at temperatures around {approx}0.1 K have been developed for the last two decades, driven mostly by the need for ultra-high energy resolution (<0.1%) in X-ray astrophysics and dark matter searches [1]. The Advanced Detector Group at Lawrence Livermore National Laboratory has developed different cryogenic detector technologies for applications ranging from X-ray astrophysics to nuclear science and non-proliferation. In particular, we have adapted… more

Damage and ablation of large band gap dielectrics induced by a 46.9 nm laser beam

Description: We applied a 0.3 mJ, 1.7 ns, 46.9 nm soft X-ray Argon laser to ablate the surface of large band gap dielectrics: CaF{sub 2} and LiF crystals. The ablation versus the fluence of the soft X-ray beam has been studied varying the fluence in the range of 0.05-3 J/cm{sup 2}. An ablation threshold of 0.06 and 0.1 J/cm{sup 2} and an ablation depth of 14 and 20 nm have been found for CaF{sub 2} and LiF, respectively. These results define new ablation conditions for these large band gap dielectrics, whic… more

The Effects of Male Age on Sperm DNA Damage in Healthy Non-Smokers

Description: The trend for men to have children at older ages raises concerns that advancing age may increase the production of genetically defective sperm, increasing the risks of transmitting germ-line mutations. We investigated the associations between male age and sperm DNA damage and the influence of several lifestyle factors in a healthy non-clinical group of 80 non-smokers (age: 22-80) with no known fertility problems using the sperm Comet analyses. The average percent of DNA that migrated out of the… more

Thermal Stability of LiPF6 Salt and Li-ion Battery ElectrolytesContaining LiPF6

Description: The thermal stability of the neat LiPF6 salt and of 1 molal solutions of LiPF6 in prototypical Li-ion battery solvents was studied with thermogravimetric analysis (TGA) and on-line FTIR. Pure LiPF6 salt is thermally stable up to 380 K in a dry inert atmosphere, and its decomposition path is a simple dissociation producing LiF as solid and PF5 as gaseous products. In the presence of water (300 ppm) in the carrier gas, its decomposition onset temperature is lowered as a result of direct thermal r… more

SUPPLEMENTAL ON-LINE MATERIAL, INFLUENCE OF pH ON PLUTONIUM DESORPTION/SOLUBILIZATION FROM SEDIMENT

Description: The oxidation state distribution of Pu in each sample for each reaction time was measured using a combined ultrafiltration and solvent extraction technique (1-4). First the oxidation state distribution of aqueous Pu is measured. Then the total system (solid and aqueous phase combined) Pu oxidation state distribution is measured by lowering the pH to leach Pu from the solid phase. For each reaction time, a 2.5-mL aliquot of the aqueous phase was removed and passed through a 12-nm filter (Microse… more
