72486-With the ever increasing number of smaller animals, such as mice and rats, being used as human disease models, the demand for small animal imaging also has increased. In particular, the pharmaceutical industry requires the in vivo quantification of biological processes, to measure the mechanism of action of a pharmacological agent and its concentration at the site of action. High-resolutio ...

75524-Single photon emission computed tomography (SPECT) maintains an important role in the study of disease models in small animals as well as in patient care. Although rich in physiological information content, interpretation of SPECT data for these studies is challenging because SPECT images lack anatomical information. Dual-modality imaging, which combines radionuclide imaging with anatomica ...

72904-Aerosol particles have important impacts on visibility, acid deposition, climate, and human health, although large uncertainties remain on their quantification. A significant part of the anthropogenic aerosol is generated from energy-related activities, and organic compounds are known to account for a large part of ambient aerosol mass in many locations. However, the measurement of the com ...

The Combat Rubber Raiding Craft (Small) (CRRC(S)) is used by Special Operations Forces (SOF). The current craft, underway, produces a highly discernible bow wave that enhances its probability of detection. A primary means of reducing the detect- ability of the CRRC(S) is to decrease the bow wave and wake of the craft that will enhance the survivability of the craft and crew in the combat arena. To ...

THE USE OF HIGH ENERGY (E ~ 2 TO 19 MEV) ELECTRON BEAMS (HEEB) AT HIGH AVERAGE POWER (P ~ 50 KW TO 1 MW) ALLOWS COMPRESSION ANNEALED PYROLYTIC GRAPHITE (CAPG) AND CARBON-CARBON (CC) COMPOSITE COMPONENTS TO BE JOINED TO METALLIC SUBSTRATES WITHOUT THE HIGH RESIDUAL STRESSES THAT ACCOMPANY CONVENTIONAL BRAZING. RELIABLE BRAZING OF CAPG AND CC TO COPPER ALLOYS IS NECESSARY TO FABRICATE PLASMA LIMITE ...

76219-In order to minimize our dependence on foreign fossil fuels and improve our environment, the DOE has embarked on the development of hydrogen-based power production. As part of this development, it will be necessary to separate hydrogen from the synthesis gas derived from coal gasification, an operation requiring high-temperature membranes. This project will develop chemically durable, SiC- ...

The ATLAS-VOTER Toolkit is physics based with detailed aircraft models, environmental effects, operator, instructor, and analyst work stations, High Energy Laser (HEL) modeling, and graphic user interfaces. Because of the maturity of its component softwar

Special Operations Forces have a diverse set of needs and desires because of the wide variety of mission scenarios and conditions they undertake. This presents significant challenges for the design and manufacture of soldier garments to augment the performance of SOF operators in the field. Foster-Miller and its team have proposed a lightweight, dynamic vest design that will include and/or accom ...

75055-Conventional fuel cells, based on either a strip cell design or a bipolar plate design, have limitations in the trade-off between weight and power ¿ i.e., high power is obtained by adding weight. However, portable power applications will require that the fuel cell provide sufficient power to an external device, yet be light enough to be carried around by a consumer. This project will deve ...

75170-X-ray detectors with high energy resolution, high sensitivity, and high count-rate performance are required in electron beam systems for materials science research. In many X-ray detection studies conducted with electron beam systems, system performance is limited by the characteristics of available X-ray detectors. This project will develop novel low-capacitance, high-purity silicon detec ...
