Commercial Aviation: Legacy Airlines Must Further Reduce Costs to Restore Profitability

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since 2001, the U.S. airline industry has confronted financial losses of previously unseen proportions. From 2001 to 2003, the industry lost $23 billion, and two of the nation's biggest airlines have gone into bankruptcy. To assist airlines, the Congress provided U.S. airlines with $7 billion of direct financial assistance--most recently in the form of $2.4 billion of financial assistance under the 2003… more

Air Pollution: EPA Could Take Additional Steps to Help Maximize the Benefits from the 2007 Diesel Emissions Standards

Description: A letter report issued by the General Accounting Office with an abstract that begins "Diesel engine emissions pose health risks, but one major source--heavy-duty diesel vehicles--is critical for our economy. To reduce risks, the Environmental Protection Agency (EPA) has set stringent emissions standards for diesel engines. In 1998, EPA found that some engine makers were violating standards, so they agreed to build engines that meet 2004 standards early, by October 2002. EPA has set even more st… more

Emerging Energy-Efficient Technologies in Buildings Technology Characterizations for Energy Modeling

Description: The energy use in America's commercial and residential building sectors is large and growing. Over 38 quadrillion Btus (Quads) of primary energy were consumed in 2002, representing 39% of total U.S. energy consumption. While the energy use in buildings is expected to grow to 52 Quads by 2025, a large number of energy-related technologies exist that could curtail this increase. In recent years, improvements in such items as high efficiency refrigerators, compact fluorescent lights, high-SEER air… more

A Study of the Ion Hose Instability in the DARHT-II Downstream Transport Region

Description: The second axis of the DARHT flash X-ray facility at Los Alamos National Laboratory (''DARHT-II'') is a multiple-pulse, 18.4 MeV, 2 kA induction electron linear accelerator [1]. A train of short ({approx}50 ns) pulses are converted via bremsstrahlung to X-rays, which are then used to make radiographic images at various times (nominally four) during a ''hydrotest'' experiment. The train of pulses is created by carving them out of a two microsecond long macropulse, using a fast switching element … more

Rapid Generation of a Nanocrystal-Labeled Peptide Library for Specific Identification of the Bacterium Clostrium Botulinum

Description: Several peptide libraries containing up to 2 million unique peptide ligands have been synthesized. The peptides are attached onto a 80 micron resin and the length of these peptide ligands ranges from 5 to 9 amino acid residues. Using a novel calorimetric assay, the libraries were screened for binding to the ganglioside-binding domain of Clostridium Tetanus Toxin, a structural similar analog of the Clostridium Botulinum toxin. Several binding peptide sequences were identified, in which the detai… more

Methods for Calibrating Basin-Wide Hydroacoustic Propagation in the Indian Ocean

Description: This collaborative project was designed to test and compare methods for achieving full ocean basin propagation of hydroacoustic signals in the 5-100 Hz frequency band. Plans for a systematic calibration of the International Monitoring System (IMS) for nuclear testing were under consideration in 2000/2001. The results from this project provide information to guide such planning for future ocean basin calibration work. Several acoustic source types were tested during two sea-going experiments and… more

Analysis of design tradeoffs for diplay case evaporators

Description: A model for simulating a display case evaporator under frosting conditions has been developed, using a quasi-steady and finite-volume approach and a Newton-Raphson based solution algorithm. It is capable of simulating evaporators with multiple modules having different geometries, e.g. tube and fin thicknesses and pitch. The model was validated against data taken at two-minute intervals from a well-instrumented medium-temperature vertical display case, for two evaporators having very different c… more

Geochemistry of Hydrofluoric Acid in Kaolinitic Soils

Description: This document explores the geochemical reactions likely to occur when hydrofluoric acid is spilled on Savannah River Site (SRS) soil. In particular, we evaluate the potential of environmental damage from a one-time release of concentrated hydrofluoric acid into a trench. According to interviews with personnel involved, sometime between 1955 and 1960 drums of 50-60 per cent hydrofluoric acid were disposed in a trench in the Central Shops area. The method of disposal suggests that most of the aci… more
