Abstract:Thermal control of a space satellite in orbit is usually accomplished by balancing the energy emitted by the satellite as infrared radiation against the energy dissipated by internal electrical (and other) sources plus energy absorbed from the environment. Due to changing conditions as the satellite… more
Abstract:DESCRIPTION: (Adapted from the Applicant's Abstact): LI-COR has combined solid-state optical technology with infrared fluorescent dye chemistry to detect and quantify DNA products with extremely high sensitivity. The applicant proposes to extend LI-COR's near-infrared (NIR) fluorescence technology… more
Abstract:A large number of RFLP variants in plant and animal diseases can be detected using the polymerase chain reaction (PCR) followed by restriction endonuclease cleavage. However, the resolution of PCR fingerprinting techniques is limited by rather long (4 to 6 base pair) DNA sequence specificities of… more
Abstract:Rural communities are threatened by declining economic performance, loss of population, andlack of opportunity. Telecommunications offers promise for rural revitalization by capitalizingon the wage disparity between urban and rural economies. The proposed research will examineefforts to date in… more
Abstract:The primary problem in organ transplantation today is the shortage of human donors. A proposed soluuse of pigs, but the risk of rejection is currently too great. The ultimate goal for transplant recispecific immune tolerance. They would then accept their grafts as "self' without immune suppression… more
Abstract:Tools for engineering of complex, embedded, high-performing real-time systems comprise a critical technology area. 21st Century Systems, Inc. proposes to design and eventually (in Phases II and III) develop and commercialize an environment tool-suite that will perform systems synthesis for such… more
Abstract:Chlorella virus (Cvi) restriction nucleases are a large, untapped source of gene mapping tools that have considerable commercial potential. Unlike bacterial restriction endonucleases, which recognize 4 to 8 base pair (bp) DNA target sequences, Cvi endonucleases define unique 2 to 4 bp cleavage sites… more
Abstract:The primary long term objective will be the large scale production of novel organometallic reagents prepared from highly reactive Rieke Metals. Primary metals to be examined include zinc, magnesium, copper, and calcium. The development of highly reactive Rieke Metals allows the direct oxidative… more
Abstract:Resin transfer modling (RTM) offers many advantages over hadn lay-up of prepreg or wet filament winding in the production of advanced composites. Successful application of RTM requires complete resin infiltration of the molded dry fiber preform. Uncertainty in the resin infiltration process due to… more
Abstract:Our company will develop an immunoassay that can be used in screening programs fordetermination of blood lead levels. Monoclonal antibodies specific for delta-aminolevulinic acid (ALAD)and lead will be used to investigate the feasibility of their use for detection of lead bound to ALAD inan… more
Abstract:THIS PHASE II PROJECT WILL DEVELOP TRAINING MATERIALS, INCLUDING A MANUAL, TO ASSIST NATIVE AMERICAN TRIBES, COMMUNITIES AND ORGANIZATIONS IN THEIR COMPREHENSIVE TOURISM DEVELOPMENT PLANNING AND IMPLEMENTATION. FURTHER, THE PROJECT WILL PLAN AND CONDUCT A WORKSHOP, INVOLVING A CROSS SECTION OF… more
Abstract:THE NEED FOR SMALLER SEMICONDUCTOR DEVICE STRUCTURES FOR USE IN VERY HIGH SPEED MICROELECTRONICS REQUIRES A NEW GENERATION OF PLASMA ETCHING TECHNOLOGY. ECR PROMISES TO PROVIDE FEATURES AS SMALL AS 0.2 MICRONS IN SIZE, AS WELL AS A HIGH DEGREE OF ETCHING ANISOTROPY, SELECTIVITY, ETCH RATES, AND LOW… more
Abstract:II-VI SEMICONDUCTORS, ESPECIALLY HGCDTE, ARE USED EXTENSIVELY IN INFRARED IMAGING AND NIGHT VISION ELECTRONICS. THESE SEMICONDUCTORS HAVE SOFT SURFACES; GROWTH OF DEVICE QUALITY MATERIAL IS DIFFICULT; DEVICE YIELDS ARE LOW, AND COSTS ARE HIGH. THERE IS THUS A GREAT NEED FOR NON-INVASIVE PROCESS… more
Abstract:Targets designed to withstand the effects of conventional (nonnuclear) munitions are assessed using standard vulnerability assessment methods. These assessment tools usually consider variabilities in site characteristics, target attributes like strength and stiffness, and weapon delivery… more
Abstract:IN THIS PROPOSAL WE OFFER TO DEVELOP FOR THE DEFENSE NUCLEAR AGENCY A SOFTWARE DESIGN FRAMEWORK THAT CAN BE USED BY ALL OF DNA'S CONTRACT ORGANIZATIONS FOR THEIR OWN INDIVIDUALLY TAILORED DNA COMPUTATIONAL SOFTWARE--EXISTING OR DEVELOPMENTAL. THIS FRAMEWORK MAKES USE OF NEWLY DEVELOPED… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
