Abstract:BERYLLIUM IS A CANDIDATE MATERIAL FOR APPLICATIONS REQUIRING LOW DENSITY, STRENGTH, AND/OR THERMAL PERFORMANCE, SUCH AS SPACE STRUCTURES, HEAT SHIELDS, RADIATORS, AND ELECTRONICS. HOWEVER, THE USE OF BERYLLIUM IS LIMITED BY ITS MODERATE THERMAL CONDUCTIVITY AND BRITTLENESS, BOTH OF WHICH RESULT IN… more
Abstract:DIFFERENTIATING AMONG THE DENOMINATIONS OF U.S. CURRENCY IS A PROBLEM FOR THE VISUALLY HANDICAPPED. CURRENTLY AVAILABLE DEVICES THAT ASSIST THE BLIND IN DETERMINING CURRENCY DENOMINATIONS ARE RELATIVELY LARGE AND EXPENSIVE. THE PROPOSED RESEARCH AND DEVELOPMENT IS A SYSTEMATIC APPLICATION OF PATTERN… more
Abstract:DUE TO THE EFFECTIVENESS OF FIBROUS MATERIALS IN SUPPRESSING RADIATIVE ENERGY TRANSPORT, THEY ARE WIDELY USED FOR THERMAL INSULATION IN MANY ENGINEERING SYSTEMS, SUCH AS THE SPACE SHUTTLE THERMAL PROTECTION TILES, LINERS OF COMBUSTION ENGINES, FLEXIBLE HEAT SHIELDS IN REENTRY VEHICLES, ETC. OF… more
Abstract:Epitaxial growth of the aluminum gallium nitride (AlGaN) material system by molecular beam epitaxy (MBE) has been hindered by the lack of a suitable nitrogen source. The deposition of AlGaN at typical MBE growth temperatures results in nitrogen deficient films that suffer from low growth rates and… more
Abstract:The specific proposed innovation is the use of an active radiometer in place of conventional radar techniques for measuring rainfall over the earth's surface from satellite platforms. This technique provides a substantial savings in data acquisition time that can be used to increase the scan rate… more
Abstract:Currently all oxygen used in USAF, Navy and US Army is produced by means of either cryogenic distillation (liquid oxygen) or pressure swing adsorption (PSA). Both methods have significant disadvantages. Currently employed PSA systems, in particular, are limited to 90-95% purity of oxygen produced.… more
Abstract:AMOCO PROCESS ACTIVATED CARBONS HAVE BEEN FOUND TO HAVE HIGH STORAGE CAPACITY FOR ALTERNATE FUEL VEHICLE ENERGY SOURCES SUCH AS HYDROGEN AND METHANE. NEARLY ALL OF THE GAS THESE CARBONS CAN STORE IS ADSORBED IN MICROPOROUS REGIONS WHERE PORE DIAMETERS ARE LESS THAN 40 A. HOWEVER, THE MICROPORES… more
Abstract:Although the mechanisms of taxol antitumor activities and toxicity are not understood at themolecular level, they must involve interactions between the drug and various receptors on athree-dimensional level. Therefore, a rational way to achieve more selective taxol analogues would beto determine the… more
Abstract:ACTIVE RADIO FREQUENCY CAVITY (PATENT PENDING0, OR ARFC, IS A CONCEPT WHICH ENABLES THE INTEGRATION OF A LARGE NUMBER OF LOW-POWER TRANSISTERS OR OTHER SOLID STATE DEVICES INTO A RESONANT RF CAVITY, FORMING A MONOLITHIC LIGHT-WEIGHT, HIGH-EFFECIENCY, HIGH-POWER STRUCTURE. THE LOW OPERATING VOLTAGE… more
Abstract:Mice lacking a functional c-src gene develop osteopetrosis due to a defect in bone resorption by osteoclasts (1). This evidence implicates the role of Src in osteoclast resorption activity. We aim to develop a drug that blocks the action of Src protein kinase as a potential treatment of osteoporosis… more
Abstract:ORMASIL-DIAMOND composite coatings, made via the sol-gel method have great promise for thermal management applications. They are easy to apply, have excellent stability and can be cured at low temperatures. Recent work has provided the knowledge to tailor ORMASIL properties for this application. An… more
Abstract:THE OBJECTIVE IS TO DEVELOP A MINIATURIZED SIX DEGREES-OF-FREEDOM (6D) TRACKING APPARATUS FOR USE WITH THREE DIMENSIONAL (3D) ULTRASOUND AND MEDICAL IMAGING EQUIPMENT. SUCH A TOOL COULD ENABLE CLINICIANS TO STUDY HUMAN ANATOMY AND BODILY FUNCTIONS IN THREE DIMENSIONS. IN PURSUIT OF THIS GOAL,… 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.
