APPLICATION OF ADVANCED ORGANIC COMPOSITE AT CRYOGENIC TEMPERATURE IS OF CURRENT INTEREST. HOWEVER, RELATIVELY LIMITED DEVELOPMENT WORK HAS BEEN DONE IN THIS AREA. OUR UNDERSTANDING OF THE MECHANICAL AND CHEMICAL BEHAVIOR OF AN ORGANIC COMPOSITE MATERIAL AT CRYOGENIC ENVIRONMENT IS SOMEWHAT LACKING. IN ORDER TO UNDERSTAND THE FUNDAMENTAL MECHANISMS THAT AFFECT THE PERFORMANCE OF AN ORGANIC COMPOSI ...

A RAPID HIGH RECOVERY DIAFILTRATION PROCESS FOR THE SEPARATION AND PURIFICATION OF BIOLOGICALLY ACTIVE PROTEINS AND PEPTIDES WILL BE DEVELOPED AND DEMONSTRATED. THE MILD PROCESS CONDITIONS AND SIZE SELECTIVITY OF MEMBRANE FILTRATION WILL BE USED TO RECOVER BIOLOGICALLY PRODUCED FUSION PROTEINS OF 15,000 TO 20,000 MOLECULAR WEIGHT. THE FUSION PROTEIN WILL BE CONSTRUCTED TO CONTAIN THE DESIRED BIOLO ...

THE OBJECTIVE OF THIS STUDY IS TO DEVELOP AN IN VITRO CULTURE SYSTEM TO SUPPORT NORMAL DEVELOPMENT OF EARLY STAGE EMBRYOS TO BLASTOCYST STAGES. A SERIES OF FOUR EXPERIMENTS ARE PROPOSED IN WHICH FOUR TREATMENTS; 1) BOVINE TROPHOBLASTIC VESICLES, 2) FETAL BOVINE UTERINE CELLS, 3) OVIDUCTAL EPITHELIAL CELLS AND 4) SHELL-FREE CHICK EMBRYOS ARE USED AS FEEDER CELLS TO CO-CULTURE WITH EITHER MOUSE OR G ...

A COMBINED EXPERIMENTAL AND ANALYTICAL STUDY IS PLANNED TO DEVELOP ADVANCED COMPOSITE PIPING SYSTEMS. DUAL WALL PIPE WILL BE DEVELOPED AND TESTED FOR IMPROVED IMPACT RESISTANCE AND TOUGHNESS. EPOXY AND POLYESTER RESINS WILL BE USED IN COMPOSITE PIPE SECTIONS AND BONDED WITH EPOXY ADHESIVES AS WELL AS WITH HEAT-SHRINKABLE ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE AND ADVANCED ELASTMERIC COUPLINGS AN ...

MANY INDIVIDUALS WITH DISABILITIES WOULD BENEFIT FROM IMPROVED METHODS FOR VOICE INPUT INTO, AND VOICE OUTPUT FROM, MICROCOMPUTERS. THE ADVANTAGES OF COMPUTERIZED VOICE OUTPUT FROM PRINTED MATERIAL FOR BLIND OR VISUALLY IMPAIRED INDIVIDUALS IS OBVIOUS. VERY OFTEN, INDIVIDUALS WITH LANGUAGE-LEARNING DISABILITIES FALL INTO THIS CATEGORY. THEADVANTAGES OF SYNTHESIZED SPEECH IS OBVIOUS FOR INDIVIDUALS ...

PHASE I OF THIS PROJECT WILL EVALUATE THE TECHNICAL FEASIBILITY OF DEVELOPING A COMMERCIALLY VIABLE RADIOISOTOPEGENERATOR FOR DESPENSING, ON DEMAND, A SHORT-LIVED RADIOISOTOPE ((199M)AU, 30 6 ). EMPHASIS WILL BE GIVEN TO EVALUATING THE (7195M)HG- (195M)AU) GENERATOR AND A COMPATIBLE ELUENT. THIS ISOTOPE CAN BE USED IN THE NONINVASIVE DIAGNOSIS AND CARDIAC ASSESSMENT OF HEART DISEASE PATIENTS WITH ...

TECHNOLOGY INTERNATIONAL INCORPORATED (TII) PROPOSES A PROGRAM TO DESIGN, TEST, AND MANUFACTURE A MINE AND EXPLOSIVES DETECTION CAPABILITY EMPLOYING X-RAYS (MINEDECX), UTILIZING MULTIPLE-ENERGY BACKSCATTER IMAGING. THE MINEDECX IS EXPECTED TO PROVIDE A PRECISE MEANS OF DETECTING BURIED ANTI-VEHICULAR AND ANTI-PERSONNEL LAND MINES. THE MAIN GOALS INCLUDE, DESIGN AND EVENTUAL FABRICATION OF A MINE D ...

TECHNOLOGY INTERNATIONAL INCORPORATED (TII) IS PROPOSING THE CONSTRUCTION OF A DETECTABLE DEFECT DRIFT DIFFUSION (D4) MODEL FOR PREDICTION OF HELICOPTER GEARBOX LIFE EXPECTANCY. THE MODELING STRATEGY IS BASED ON PREDICTING FATIGUE OF TYPICAL MECHANICAL EQUIPMENT WITH ROLLING CONTACT, SUCH AS ROLLING ELEMENT BEARING AND GEAR OF THE HELICOPTER GEARBOX. THE RATE OF GROWTH OF SPECIFIC SIZES AND TYPES ...

PIEZOELECTRIC CRYSTAL DETECTORS WILL BE DEVELOPED AS PERSONAL MONITORS WHICH CAN BE USED TO DETECT EXPOSURE TO TOXIC COMPOUNDS INDOORS, AT WORK-PLACE SITES. CRYSTALS WILLBE COATED WITH SELECTIVE ADSORBENTS FOR THE POLLUTANTS TO BEASSAYED. DETECTION OF PPB CONCENTRATIONS, EITHER CONTINUOUSLY OR AS A DOSIMETER, WILL BE POSSIBLE. EACH DETECTOR, AND ADSORBENT, WILL BE EVALUATED WITH RESPECT TO SENSITI ...
