Abstract:CONCURRENT ENGINEERING IS A CRUCIAL METHODOLOGY IN REDUCING DEVELOPMENT COST AND TIME OF HARDWARE AND ITS COMPLEMENTING SOFTWARE. TODAY NO TOOLS ARE AVAILABLE THAT CAN PROVIDE A TIGHT INTEGRATION OF HARDWARE AND SOFTWARE DEVELOPMENT (CO-DESIGN). ASC PROPOSES THE DEVELOPMENT OF VIOOL (VHDL… more
Abstract:Requirements on ATR (Automatic Target Recognition) performance are becoming more stringent. ATR systems are expected to detect, classify, recognize, and even identify, threats with greater accuracy and in less time over an increasing range of scenarios. Similarly, operators in manned combat systems… more
Abstract:Interleukin-8 (IL-8), a newly characterized proinflammatory cytokine, is chemotactic for polymorphonuclear neutrophils (PMNs) and stimulates several other agonist effects, all culminating in accumulation at the site of infection or inflammation and the full plethora of effects, including tissue… more
Abstract:We will characterize the pharmokinetics of a peptide GPIIb/IIIa receptor antagonist in a caninemodel. Our research has three specific aims. In the first aim, the applicant intends to fully characterizethe pharmokinetics of P246, a 12 residue GPIIb/IIIa receptor antagonist peptide, in a ac dog model… more
Abstract:As neutrophils are the first type of leukocyte to localize to a site of infection, small syntheticpeptides that bind with high affinity to cell-surface receptors that mediate chemotaxis of neutrophilsprovide a rational basis for the development of an infection specific radiopharmaceutical. The… more
Abstract:THE OBJECTIVE OF THE WORK IS TO DEVELOP EFFICIENT AND ACCURATE COMPUTATIONAL TECHNIQUES FOR THE SOLUTION OF MOVING FRONT PROBLEMS SUCH AS THOSE OCCURRING IN PHASE-CHANGE, POLLUTANT DISPERSAL, GROUNDWATER TRANSPORT, AND OTHERS. MIMD PARALLEL PROCESSING IS TO BE USED TO OBTAIN THE COMPUTATIONAL SPEED… more
Abstract:AMERICA IS FALLING BEHIND IN SCIENCE TEACHING. YOUNG STUDENTS' INTEREST IN SCIENCE MUST BE STIMULATED TO MAINTAIN THE INTELLECTUAL VIGOR AND ECONOMIC COMPETITIVENESS OF THE NATION. WHO HAS NOT BEEN FASCINATED BY A SCANNING ELECTRON MICROSCOPE (SEM) PICTURE OF A FLY, OR ANT, OR GRAIN OF POLLEN WITH… more
Abstract:The resolution gap between available chip (sub-micron) and off-chip (100 to 125 micron) will be closed by a new laminate interconnection technology. Semiconductor manufacturing techniques, either on wafer (NChip) or in thin film form (IBM and others), are used to bring line widths and thicknesses… more
Abstract:ANATOMIC AND PHYSIOLOGICAL DERANGEMENTS OF THE GASTROINTESTINAL TRACT CAN LEAD TO ABNORMAL OVERGROWTH OF THE SMALL INTESTINE. A QUANTITATIVE CULTURE OF AN ASPIRATE OF SMALL BOWEL FLUID IS USED TO DETECT BACTERIAL OVERGROWTH. THIS IS OFTEN NOT PERFORMED BECAUSE IT IS SO INCONVENIENT. THE NEED FOR A… more
Abstract:The introduction emphasizes the clinical need for an artificial system which can transporthemoglobin which has been oxygenated in the lung to tissues in the body. Thus, the quest for amodality which could transport, store, and release oxygen to the tissues when required. The transportform must also… more
Abstract:THE USE OF ANTIBODIES IN COMMERCIAL IN VITRO IMMUNODIAGNOSTIC KITS AND IN OTHER RESEARCH IMMUNOASSAYS PLACES A REQUIREMENT ON ANTIBODY PRODUCTION FACILITIES AND RESEARCHERS TO PRODUCE SUITABLE HIGH TITERED POLYCLONAL AND MONOCLONAL ANTIBODIES. ADJUVANTS ARE USED TO INCREASE THE ANTIGENICITY OF… more
Abstract:RECUPERATIVE HEAT EXCHANGERS ARE KEY COMPONENTS IN REFRIGERATION SYSTEMS USED TO COOL SUPERCONDUCTING DEVICES IN HIGH ENERGY PHYSICS RESEARCH. PRESENT PLATE-FIN HEAT EXCHANGERS HAVE EFFECTIVENESS OF AROUND 0.97 AND PRESSURE DROPS OF SEVERAL PERCENT OF THE STREAM PRESSURE. APPROXIMATELY HALF THE… more
Abstract:HELIUM COOLING IS ATTRACTIVE FOR HIGH HEAT FLUX COMPONENTS IN TOKAMAK FUSION REACTORS BECAUSE THERE ARE LARGE SAFETY ADVANTAGES COMPARED TO WATER COOLANT. HOWEVER, CURRENT TECHNOLOGY FOR HELIUM COOLING IS HAMPERED BY THE COMPLEXITY OF THE HOUSING REQUIRED TO PROVIDE HELIUM TO THE NORMAL FLOW HEAT… more
Abstract:J-T cryoccolers potentially offer the best solution for sensor cooling applications. Because of the high cooling capacity per unit mass flow, the heat exchangers and J-T cryocoolers can be significantly better than that of other mechanical coolers. Despite these benefits, closed-cycle J-T… more
Abstract:Wet etching for oxide thin films is superior to dry processes because it has extremely low contamination, eliminates water markes from the wafers, provides a high degree of process flexibility and control, has better cleanliness, and the equipment is compact. However, wet etching has had limited… 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.
