Abstract:BioTechnical Communications is proposing to develop a prototype for healthcare programming targeted to African-Americans, and to broadcast on Black Entertainment Television (BET), a targeted cable television network. BioTechnical Communications will be responsible for the accuracy of the technical… more
Abstract:THIS PROJECT WILL INVESTIGATE METHODS OF EXTRACTING MICROWAVE POWER FROM A CLUSTER KLYSTRON BY COMBINING SEVERAL LOW-CURRENT, MEDIUM-POWER KLYSTRONS TO PRODUCE HIGH PEAK POWER WITH VERY HIGH EFFICIENCY. A CLUSTER KLYSTRON IN COMBINATION WITH A PULSE COMPRESSION SYSTEM CAN BE USED AS A RADIOFREQUENCY… more
Abstract:THE GOAL OF THIS PROJECT IS THE DEVELOPMENT OF A HEAVY ION STRIPPING TECHNIQUE TO ACHIEVE A HIGH CHARGE STATE BEAM. THE ION STRIPPER PROPOSED HERE COULD BE ADDED TO EXISTING SINGLE CHARGE STATE, LOW EMITTANCE, HIGH BRIGHTNESS ION SOURCES. USING HIGH CHARGE STATE BEAMS IN A DRIVER FOR HEAVY ION… more
Abstract:THE LAST THREE YEARS HAVE SEEN A DRAMATIC INCREASE IN THE NUMBER OF COMPANIES PROCESSING POST-CONSUMER PLASTICS FROM PRODUCTS SUCH AS SOFT DRINK CONTAINERS, DETERGENT BOTTLES, MILK JUGS AND WATER BOTTLES. WHILE THIS HAS TO SOME EXTENT DIVERTED THESE MATERIALS FROM LANDFILLS, IT HAS CAUSED AN… more
Abstract:DIVERSION OF PLASTICS FROM LANDFILL TO RECYCLING CAN POTENTIALLY SAVE THE ENERGY EQUIVALENT OF 60 MILLION BARRELS OF OIL ANNUALLY AND REDUCE LANDFILL VOLUME REQUIRMENTS BY UP TO 20%. THE U.S. ENVIRONMENTAL PROTECTION AGENCY HAS RECOMMENDED THAT SOURCE REDUCTION, RECYCLING, VOLUME REDUCTION, AND… more
Abstract:EACH YEAR, AMERICANS DISPOSE OF AN ESTIMATED 29 BILLION POUNDS OF PLASTICS WHICH CONSUME UP TO 20% OF OUR NATION'S ANNUAL LANDFILL CAPACITY. RECENT ENVIRONMENTAL AND POLITICAL PRESSURES HAVE LED TO RAPID ESTABLISHMENT OF PLASTICS RECYCLING FACILITIES. LIMITED MARKETS FOR LOW QUALITY RECYCLED RESINS… more
Abstract:The goal of this research is to develop critical reagents that will support the production of highvector titers for transfusion medicine, ie. hematopoietic gene therapy for treatment of blood disordersas well as other applications. Attempts at concentrating these vectors has generally resulted in… more
Abstract:The development of hematopoietic defined protein-free reagents that support megakaryocyteformation will be of inestimatable importance. The rationale for developing such reagents is that it willallow the measurement of drug toxicity in its unbound state in which all of the drug is active.… more
Abstract:The overall goal is to develop serum-free medium for the proliferation and differentiation of fetal liver, spleen and bone marrow. The culture system will be comprised of serum-free medium and various cytokines. Serum-free medium will allow the direct effect the cytokines have on the fetal… more
Abstract:Pseudomorphic InGaAs with high InAs concentrations on GaAs substrates are currently in use in complementary-heterostructure FET (C-HFET) digital and MODFET MMW circuits. While their bandgaps enable them to detect 1300 and 1550 nm light, the projected detection efficiency (responsivity) is very low… more
Abstract:A promising new approach for high power solid-state sources will be demonstrated using spatial power combining grids. Present development of high power field effect transistor (FET) based solid-state sources at millimeter-wave frequencies is hampered by the limited power output of individual sources… more
Abstract:An epitaxial grown Germanium - channel Junction Field Effect Transistor (Ge-JFET) is proposed to provide the most efficient, low noise cryogenically cooled detectors operating at 2 - 4Â¿K. Precisioned engineered lattice and doping epitaxial growth will eliminate material defects to allow the… more
Abstract:To meet the future needs for increased capabilities in military as well as commercial space communications and radar applications, the W-Band (94 Ghz) frequency spectrum utilized. A critical issue has arisen in the development of the future W-band electronic systems technology: while InP-based… more
Abstract:THE FEASIBILITY OF A SIMPLE ATMOSPHERIC CARBON DIOXIDE (CO2) SENSOR FOR OCEANOGRAPHIC DEPLOYMENT WILL BE EXPLORED IN THIS PHASE I PROJECT. THREE BASIC STEPS ARE REQUIRED FOR SENSOR OPERATION: MEMBRANE EQUILIBRATION OF GASEOUS AND AQUEOUS CO2, CHEMICAL AMPLIFICATION OF THE CONCENTRATION OF THE… more
Abstract:The proposed Fiber-Optic Chemiluminescent Biosensor concept forms the basis for the development of a new class of light weight, small, low power, inexpensive robust, accurate and extremely sensitive sensors which can be applied to various analytical requirements within the aerospace biomedical,… 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.
