Military Base Closures: Opportunities Exist to Improve Environmental Cleanup Cost Reporting and to Expedite Transfer of Unneeded Property

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The cleanup of environmental contamination on unneeded property resulting from prior defense base realignment and closure (BRAC) rounds has been a key impediment to the transfer of these properties and could be an issue in the transfer and reuse of unneeded property resulting from the 2005 BRAC round. GAO's analysis of available data indicates that, when completed, the cleanup for the four prior BRAC ro… more

Wildland Fire Management: Lack of a Cohesive Strategy Hinders Agencies' Cost-Containment Efforts

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Over the past two decades, the number of acres burned by wildland fires has increased, often threatening human lives, property, and ecosystems. The cost of responding to wildland fires has also grown, especially as more homes are built in or near wildlands, an area called the wildland-urban interface. Past management practices, including a concerted federal policy in the 20th century of suppressing fires to p… more

Military Personnel: DOD Needs to Provide a Better Link between Its Defense Strategy and Military Personnel Requirements

Description: Testimony issued by the Government Accountability Office with an abstract that begins "The war in Iraq along with other overseas operations have led to significant stress on U.S. ground forces and raised questions about whether those forces are appropriately sized and structured. In 2005, the Department of Defense (DOD) agreed with GAO's recommendation that it review military personnel requirements. The Office of the Secretary of Defense (OSD) concluded in its 2006 Quadrennial Defense Review (Q… more

A cell nanoinjector based on carbon nanotubes

Description: Technologies for introducing molecules into living cells are vital for probing the physical properties and biochemical interactions that govern the cell's behavior. Here we report the development of a nanoscale cell injection system-termed the nanoinjector-that uses carbon nanotubes to deliver cargo into cells. A single multi-walled carbon nanotube attached to an atomic force microscope tip was functionalized with cargo via a disulfide-based linker. Penetration of cell membranes with this 'nano… more

The Standard Chemical-Thermodynamic Properties of Phosphorus and Some of its Key Compounds and Aqueous Species: An Evaluation of Differences between the Previous Recommendations of NBS/NIST and CODATA

Description: The aqueous chemistry of phosphorus is dominated by P(V), which under typical environmental conditions (and depending on pH and concentration) can be present as the orthophosphate ions H{sub 3}PO{sub 4}{sup 0}(aq), H{sub 2}PO{sub 4}{sup -}(aq), HPO{sub 4}{sup 2-}(aq), or PO{sub 4}{sup 3-}(aq). Many divalent, trivalent, and tetravalent metal ions form sparingly soluble orthophosphate phases that, depending on the solution pH and concentrations of phosphate and metal ions, can be solubility limit… more

Selected International Depreciation Rates by Asset and Country

Description: The depreciation provisions in the U.S. tax system are of recurring interest to Congress. More than 100 bills were introduced in the 109th Congress that addressed some aspect of depreciation. Concerns about the U.S. depreciation system tend to begin with the criticism that updates to the system have not kept pace with technological advancements of the assets for which it is utilized to account. This report provides information on the depreciation systems of selected European Union countries (Fr… more

Total Dissolved Gas Monitoring in Chum Salmon Spawning Gravels Below Bonneville Dam

Description: At the request of the U.S. Army Corps of Engineers (Portland District), Pacific Northwest National Laboratory (PNNL) conducted research to determine whether total dissolved gas concentrations are elevated in chum salmon redds during spring spill operations at Bonneville Dam. The study involved monitoring the total dissolved gas levels at egg pocket depth and in the river at two chum salmon spawning locations downstream from Bonneville Dam. Dissolved atmospheric gas supersaturation generated by … more

A Numerical Investigation into the Anomalous Slight NOx Increase when Burning Biodiesel: A New (Old) Theory

Description: Biodiesel is a notable alternative to petroleum derived diesel fuel because it comes from natural domestic sources and thus reduces dependence on diminishing petroleum fuel from foreign sources, it likely lowers lifecycle greenhouse gas emissions, and it lowers an engine's emission of most pollutants as compared to petroleum derived diesel. However, the use of biodiesel often slightly increases a diesel engine's emission of smog forming nitrogen oxides (NO{sub x}) relative to petroleum diesel. … more

Liquid metal Flow Meter - Final Report

Description: Measuring the flow of liquid metal presents serious challenges. Current commercially-available flow meters use ultrasonic, electromagnetic, and other technologies to measure flow, but are inadequate for liquid metal flow measurement because of the high temperatures required by most liquid metals. As a result of the reactivity and high temperatures of most liquid metals, corrosion and leakage become very serious safety concerns. The purpose of this project is to develop a flow meter for Lockheed… more

New Results on Fission Cross Sections in Actinide Nuclei using the Surrogate Ratio Method and on Conversion Coefficients in Triaxial Strongly Deformed Bands in 167Lu from ICE Ball and Gammasphere

Description: The surrogate ratio technique is described. New results for neutron induced fission cross sections on actinide nuclei, obtained using this technique are presented. The results benchmark the surrogate ratio technique and indicate that the method is accurate to within 5% over a wide energy range. New results for internal conversion coefficients in triaxial strongly deformed bands in {sup 167}Lu are also presented.

Implementation of the Polarized HD target at the Thomas Jefferson National Accelerator Facility

Description: The original goal of this proposal was to study frozen spin polarized targets (HD target and other technologies) and produce a conceptual design report for the implementation of such a target in the HALL B detector of the Thomas Jefferson National Accelerator Facility (JLab). During the first two years of the proposal, we came to the conclusion that the best suited target for JLab was a frozen spin target and helped with the design of such a target. We have not only achieved our original goal b… more

Final Scientific Report, Integrated Seismic Event Detection and Location by Advanced Array Processing

Description: In the field of nuclear explosion monitoring, it has become a priority to detect, locate, and identify seismic events down to increasingly small magnitudes. The consideration of smaller seismic events has implications for a reliable monitoring regime. Firstly, the number of events to be considered increases greatly; an exponential increase in naturally occurring seismicity is compounded by large numbers of seismic signals generated by human activity. Secondly, the signals from smaller events be… more

Radio-Loudness of Active Galactic Nuclei: Observational Facts and Theoretical Implications

Description: We investigate how the total radio luminosity of AGN-powered radio sources depends on their accretion luminosity and the central black hole mass. Our studies cover about seven orders of magnitude in accretion luminosity (expressed in Eddington units, i.e. as Eddington ratios) and the full range of AGN black hole masses. We find that AGNs form two distinct and well separated sequences on the radio-loudness--Eddington-ratio plane. The ''upper'' sequence is formed by radio selected AGNs, the ''low… more

Mode-of-Action Uncertainty for Dual-Mode Carcinogens:Lower Bounds for Naphthalene-Induced Nasal Tumors in Rats Implied byPBPK and 2-Stage Stochastic Cancer Risk Models

Description: As reflected in the 2005 USEPA Guidelines for Cancer Risk Assessment, some chemical carcinogens may have a site-specific mode of action (MOA) that is dual, involving mutation in addition to cell-killing induced hyperplasia. Although genotoxicity may contribute to increased risk at all doses, the Guidelines imply that for dual MOA (DMOA) carcinogens, judgment be used to compare and assess results obtained using separate ''linear'' (genotoxic) vs. ''nonlinear'' (nongenotoxic) approaches to low-le… more
