Abstract:The problem with the current chimpanzee model for evaluating HIV prophylactics is both availability and cost of the animals. Similarly, the SIV model is limited since protection studies in primates illustrated that the immune protective epitopes of SIV envelope glycoprotein are structurally very… more
Abstract:LIGHT SCATTERING (LS) IS ONE OF THE MOST COMMON TECHNIQUES FOR POLYMER CHARACTERIZATION. THE LS INTENSITY AND ITS ANGULAR DISSYMMETRY ARE THE TWO EXPERIMENTAL RESULTS THAT GIVE THE POLYMER MOLECULAR WEIGHT (MW) AND MOLECULAR SIZE (RADIUS-OF-GYRATION RG) INFORMATION RESPECTIVELY. WHEN A MULTI-ANGLE… more
Abstract:THE PROCESSES AND EQUIPMENT FOR HANDLING SOLIDS AND SLURRIES ARE QUITE INEFFICIENT WHEN COMPARED WITH EQUIPMENT THAT HANDLES LIQUIDS AND GASES. THIS IS LARGELY BECAUSE DESIGNERS DO NOT CLEARLY UNDERSTAND THE BEHAVIOR OF GRANULAR SOLIDS AND SLURRIES SUCH AS COAL-WATER SLURRIES. IN PHASE I OF THIS… more
Abstract:IT HAS BEEN RECOGNIZED BY BOTH THE AIR FORCE AND NASA THAT SPACE DEBRIS IN THE GROWING HAZARD TO SPACE OPERATIONS. OF PARTICULAR IMPORTANCE ARE DEBRIS IN THE 0.1 - 10 CM SIZE RANGE. OVER THIS RANGE, DEBRIS DATABASES (AND CONSEQUENTLY DEBRIS MADELS) ARE DEFICIENT. ALSO, THESE PARTICILE SIZES ARE… more
Abstract:IT IS PROPOSED TO DEVELOP AN INNOVATIVE TARGETING/TRACKING LIDAR SYSTEM WHICH WILL HAVE THE CAPABILITY OF ACQUIRING, IMAGING AND TRACKING DESIGNED TARGETS AND BACKROUNDS. THE LIDAR SYSTEM WILL BE ABLE TO OPERATE OVER MULTIPLE WAVELENGTHS AND HAVE THE CAPABILITY FOR POLARIZATION ANALYSIS OF THE… more
Abstract:As the USAF works towards extending the performance envelope of its moder high performance aircraft and advanced re-entry vehicles, it is beginning to encounter multiple problems created by the presence of high temperature plasmas. The source of the plasma may vary from a jet or rocket engine plume… more
Abstract:This exploratory development is directed toward finding new methods of using artificially modified ionospheric regions for extending and enhancing communication (C3I) and surveillance (radar) capabilities. Specifically, the investigation, starting with a Phase I feasibility and planning effort and… more
Abstract:OLDER ADULTS HAVE MORE TRAFFIC CONVICTIONS AND ACCIDENTS AND INCUR MORE FATALITIES PER MILE DRIVEN THAN ANY OTHER AGE GROUP. THE AIM OF THE RESEARCH IS TWO-FOLD: 1) TO TAKE THE RESEARCH PARADIGMS DEMONSTRATED TO BE RELATED TO A VARIETY OF EVERYDAY FUNCTIONAL VISION PROBLEMS IN OLDER ADULTS AND… more
Abstract:WE INTEND TO GENERATE PRESCRIBED NEGATIVE CYLINDER EXCIMER LASER ABLATIONS USING TECHNOLOGY ANALOGOUS TO THAT PRESENTLY BEING USED FOR THE CORRECTION OF MYOPIA IN HUMAN CLINICAL TRIALS. THE DEVICE WOULD CORRECT HIGH AMOUNTS OF ASTIGMATISM FOR WHICH TREATMENT WITH GLASSES AND CONTACT LENSES IS… more
Abstract:We will develop a multigas analyzer for anesthesia that is based on an innovative technology. This unique device for anesthesia and respiratory monitoring has the potential to significantly reduce the cost of health care without lowering the level of care. The instrument is based on a new analyzer… more
Abstract:ONE OF THE KEY DIFFICULTIES FOR STUDENTS WITH LIMITED UPPER EXTREMITY COORDINATION IS THE RETRIEVAL OF APPROPRIATE MATERIALS WITH WHICH TO STUDY. CONVENTIONAL FILING SYSTEMS ARE NOT APPROPRIATE FOR USE WITH A MOUTHSTICK AND ATTEMPTS AT FILE SYSTEMS BASED ON THE "LAZY SUSAN" CONCEPT PRESENT A NUMBER… more
Abstract:Medication non-compliance is one of the greatest problems associated with maintaining the health of the elderly. Studies state that up to 23% nursing home and 10% of hospital admissions of the elderly are due to poor medication compliance. Current attempts to electronically augmented compliance have… more
Abstract:The long term objective is development of ultrasonic modules for laparoscopic surgery suitable for the minimally invasive removal of cancerous tissue. Modules will operate on the principle of tissue emulsification using ultrasonic oscillations, produced by a vibrating titanium tube, coming in… more
Abstract:THE PLANNED PROJECT TO DEVELOP A VIRTUAL ENVIRONMENTAL WORKSTATION FOR ENERGY EDUCATION (VEWEE) WILL INCLUDE DEMONSTRATING VIABILITY OF A VIRTUAL REALITY WORKSTATION FOR SCIENCE AND MATHEMATICS EDUCATIONAL PURPOSES USING MULTISENSORY FEEDBACK. THE VEWEE SYSTEM WILL PROVIDE COMPUTER GENERATED IMAGES… more
Abstract:THE PROBLEM IS THAT MARINE MAMMALS ARE GETTING KILLED AT AN ALARMING RATE. RECENT EVIDENCE SUGGESTS THAT HALF OF ALL (NONCALF) RIGHT WHALE DEATHS ALONG THE ATLANTIC COAST RESULT FROM HUMAN ACTIVITIES (KRAUS 1990). COLLISIONS WITH COMMERCIAL VESSELS MAY BE A MAJOR FACTOR IN THE LACK OF RECOVERY OF… more
Abstract:ADVANCES IN SENSORS, ANALOG-TO-DIGITAL CONVERTERS, AND INSTRUMENTATION IN GENERAL ARE FOSTERING A NEED FOR SIMILAR ADVANCES IN THE OUTPUT NOISE PERFORMANCE OF THE SUPPLIES THAT PROVIDE POWER TO THESE DEVICES. TO ENSURE THAT THE POWER SUPPLY NOISE DOES NOT DEGRADE OR LIMIT THE PERFORMANCE OF PRESENT… more
Abstract:WE WILL DEVELOP AND IMPLEMENT AN AUTOMATED DATA ENTRY SYSTEM TO SUPPORT THE COLLECTION OF UNIFORM AND RELIABLE INFORMATION ON ALL CHILDREN, UNDER THE AUTHORITY OF THE STATE TITLE IV-B/IV-E AGENCY, WHO ARE IN FOSTER CARE OR WHO ARE ADOPTED. PHASE I FOCUSED ON THE INITIAL STAGES OF SYSTEM DEVELOPMENT… more
Abstract:LEAD IN SOIL MUST BE TREATED IN ORDER TO REDUCE THE EXPOSURE RISK ASSOCIATED WITH LEAD MIGRATION AND LEAD BIOAVAILABILITY. SINCE THE LEVEL OF LEAD IN CONTAMINATED SOIL IS USUALLY VERY LOW, A COST-EFFECTIVE AND SAFE LEAD FIXATION TECHNOLOGY IS NEEDED. THIS RESEARCH WILL INVESTIGATE A NOVEL LEAD… more
Abstract:This research will develop thin insulating coatings for implant devices that are essentially impermeable to water and tissue fluids. Thin insulating coatings will be fabricated by a low-temperature sputtering process. High quality coatings will be formed into a specially engineered multilayer… 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.
