Abstract:SWINE DYSENTERY (SD) HAS BEEN ESTIMATED TO COST SWINE PRODUCERS IN EXCESS OF $180 MILLION ANNUALLY, AND IS QUARANTINABLE IN MOST STATES. CONFIRMATION OF THE DISEASE IS BASED ON THE DETETION OF THE BACTERIA, SERPULINA HYODYSENTERIAE, FROM INFECTED PIGS. AN ACCURATE DIAGNOSIS OF SD CURRENTLY INCLUDES… more
Abstract:Existing balloting codes do not consider all of the forces and interactions that contribute to balloting of hypervelocity projectiles. This effort will result in the definition of a complete mathematical model and the design of an appropriate, user friendly, computational model to predict… more
Abstract:Surgeons performing arthroplasty on painful, misshapen, arthritic hand joints do not have the choice of replacing the damaged joint with a prosthesis that will restore near natural movement as they would if a hip joint were being replaced. There are no effective finger joint replacements available.… more
Abstract:THIS RESEARCH SEEKS THE DEVELOPMENT AND DEMONSTRATION OF A MODEL THAT REPRESENTS THE GROUP DECISION-MAKING PROCESSES TAKING PLACE INSIDE THE CONTROL ROOM OF A NUCLEAR POWER PLANT UNDER BOTH NORMAL AND ABNORMAL OPERATING CONDITIONS. COGNITIVE DECISIONS, TEAM EFFECTS, AND DYNAMIC FEATURES ARE AMONG… more
Abstract:The research will investigate a uniquely configured optical to tactile converter which packages both the optical camera and a miniaturized vibrotactile display into a compact handheld configuration. The increased haptic awareness afforded to the user by this configuration is expected to improve the… more
Abstract:This research will investigate a blind mobility aid which uses kinesthetic feedback to intuitively communicate to the user the range and texture of surfaces in the extended environment. The handheld device will contain an infrared optical ranging module with the range output. The sensitivity and… more
Abstract:While past TNT biodegradation efforts yielded toxic metabolites through primarily reductive pathways, recent work, e.g. with the fungus P. chrysosporium has given evidence of complete TNT mineralization at typical contaminant site concentrations (e.g. 10 g/kg in soil) although only to ca. 20% over… more
Abstract:UNDERSTANDING THE INTERACTIONS OF THE CYTOKINES OF THE IMMUNE SYSTEM IN THE REGULATION OF THE IMMUNE CASCADE DURING THE HOST- DEFENSE MECHANISM IS OF INTENSE SCIENTIFIC INTEREST (1-2). NEWLY EMERGING RESEARCH ALSO DEMONSTRATE THAT SOME OF THESE MOLECULES ACT IN AN ENDOCRINE FASHION OUTSIDE THE… more
Abstract:AT THE PRESENT TIME, ALL MATURITY SORTING OF FRUITS AND VEGETABLES, SUCH AS APPLES, PEACHES ANDTOMATOES, IS ACCOMPLISHED EITHER BY HAND, BY COLOR OR BY THE USE OF THE MAGNESS-TAYLOR . EACH OF THESE TECHNIQUES HAVE MAJOR DISADVANTAGES IN THE HIGH-SPEED MATURITY GRADING OF FRUITS AND VEGETABLES. THE… more
Abstract:There are no commercial amplifiers that can operate at temperatures above 125 degrees Celsius. We will combine two comparable wide bandgap semiconducting materials to make electronic amplifiers and switches that operate at high temperatures (at least 500 degrees Celsius). These devices can be… more
Abstract:THIS PROJECT PROPOSES TO EXPLORE THE USE OF A WIDE BANDGAP SEMICONDUCTOR TO MAKE DEVICES CAPABLE OF OPERATING AT TEMPERATURES OF AT LEAST 500 0C. PN JUNCTIONS WILL BW FABRICATED. THE MAJOR THRUST WILL BE THE STUDY OF ELECTRODE TECHNOLOGY TO MAKE OHMIC CONTACTS THAT ARE STABLE AT HIGH TEMPERATURE AND… more
Abstract:WE PROPOSE TO DEVELOP AND STUDY A NEW MANUFACTURING TECHNOLOGY FOR THE EPITAXIAL GROWTH OF MULTILAYERS OF III-NITRIDES SEMICONDUCTORS (GaN AND AlGaN) AT TEMPERATURES SUBSTANTIALLY LOWER THAN PRESENTLY ACHIEVED. THE TECHNIQUE IS BASED ON THE ION BEAM DEPOSITION SYSTEM WHERE THE IONS ARE GENERATED BY… more
Abstract:THE PROPOSED RESEARCH AND DEVELOPMENT EFFORT WILL EXPLORE THE ELECTROLUMINESCENCE PROPERTIES OF RARE EARTH ELEMENTS IN A III-V SEMICONDUCTOR. THE TECHNIQUE OF IMPACT EXCITATION, CURRENTLY USED IN COMMERCIALLY AVAILABLE ELECTROLUMINESCENCE DISPLAY DEVICES, WILL BE STUDIED FOR EXCITING THE RARE EARTHS… more
Abstract:THIS PROGRAM WILL DEMONSTRATE HIGH SPECIFIC POWER, LIGHTWEIGHT, FLEXIBLE, THIN SILICON SOLAR CELLS. THESE SOLAR CELLS CAN BE DIRECTLY SUBSTITUTED FOR EXISTING STATE OF THE ART SILICON SOLAR CELLS WITH THE EFFECT OF SIGNIFICANTLY IMPROVING SPECIFIC POWER, POWER/AREA, AND POWER SUPPLY LIFE. THE… more
Abstract:AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction… more
Abstract:ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE… 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.
