CERAMATEC HAS CONDUCTED EXPLORATORY RESEARCH AND DEVELOPMENT ON MONOLITHIC AND COMPOSITE MATERIALS IN THE ZRB2 AND TIB2 SYSTEMS AND HAS OBTAINED VERY ENCOURAGING RESULTS WITH SEVERAL PROPRIETARY COMPOSITIONS/CONSTRUCTIONS. THE AVERAGE STRENGTH OF A BASELINE TIB2 COMPOSITION WAS MEASURED AT 877 MPA (127.3 KSI). COMPOSITE STRUCTURESWITH DISCONTINUOUS REINFORCEMENT HAD STRENGTHS IN THE RANGE 400-600 ...

THE OVERALL OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE THE SUCCESSFUL FABRICATION AND DENSIFICATION OF CERAMIC MATRIX COMPOSITES FORMED BY INJECTION MOLDING. TO ACCOMPLISH THIS OBJECTIVE, A DESIGNED TEST MATRIX WILL BE DEVELOPED THAT WILL SYSTEMATICALLY INVESTIGATE THE KEY INJECTION MOLDING AND DEBINDING PARAMETERS SUCH AS BINDER COMPOSITION, SOLIDS RATIO, MOLDING CONDITIONS, DEBINDING CONDITIONS ...

A FEASABILITY STUDY IS BEING CONDUCTED TOWARD DEVELOPMENT OFA STAND-ALONE DATABASE PRODUCT FOR PERSONAL COMPUTERS FEATURING LINKED ACCESS TO MULTIPLE DATABASES OF INTEREST TO MOLECULAR BIOLOGISTS. ALL DATA AND ACCESS SOFTWARE WILL BE LOCATED ON A COMPACT DISK SO THAT NO CONNECTION TO EXTERNAL COMPUTER RESOURCES WILL BE REQUIRED. THE DATABASESENVISAGED INCLUDE GENBANK (TM), PROTEIN IDENTIFICATION R ...

THE PROOF OF CONCEPT STUDY HEREIN PROPOSED DEALS WITH THE VALIDATION OF THE KEY TECHNOLOGY NEEDED TO REALIZE THE PERFORMANCE POTENTIAL OF THE UNIFIED CYCLE ENGINE (UCE) WHOSE OPERATIONAL ENVELOPE WAS EXPLORED IN THE PHASE I EFFORT. THE TECHNOLOGY TO BE VALIDATED, ALLOWS THE UCE TO EFFICIENTLY PROVIDE USEFUL AMOUNTS OF THRUST OVER A RANGE CONDITIONS FROM SEA-LEVEL STATIC TO MACH 5 AT HIGH ALTITUDE ...

IT IS DESIRABLE TO HAVE A MTHOD FOR EFFICIENT, COST EFFEC- TIVE, AND SIMULTANEOUS REMOVAL OF PB(II), AG(I), CD(II) AND HG(II) FROM POTABLE WATER TO LEVELS WELL BELOW THEIR EPA LIMITS. SUCH A METHOD COULD BE USED BY BOTH MUNICIPAL WATER WASTE TREATMENT PLALNTS. THE INTERACTION OF THE MACROCYCLE TETRAAZA-18CROWN WITH THE METALS OF INTEREST IS OF SUFFI- CIENT STRENGTH AND SELECTIVITY TO REMOVE THE ME ...

UTAH CONTAINS SIGNIFICANT RESOURCES OF TAR SANDS WHICH, IF DEVELOPED, COULD BECOME AN IMPORTANT COMPONENT OF THE NATION'S REQUIREMENTS FOR PETROLEUM PRODUCTS. THE ECONOMICSFOR PRODUCTION OF SYNCRUDE FROM UTAH TAR SANDS HAVE HISTORICALLY BEEN JUST BEYOND THE RANGE OF PROFITABILITY. PRODUCTION OF ASPHALT, HOWEVER, APPEARS TO BE PROFITABLE TODAY. CAPITAL AND OPERATING COSTS FOR PRODUCTION OF ASPHALT ...

THE APPLICATION OF PHYSICAL-CHEMICAL PRINCIPLES TO BIOLOGICAL SYSTEMS FREQUENTLY LEADS TO SITUATIONS IN WHICH THE QUANTITATIVE TREATMENT OF CONCEPTUALLY SIMPLE MODELS IS CONFOUNDED BY THE COMPLEXITY OF THE SYSTEM. SUCH IS THE CASE, FOR EXAMPLE, IN THE STUDY OF THE PERMEATION (AND POSSIBLE CONCURRENT METABOLISM) OF DRUGS THROUGH COMPLEX BIOLOGICAL MEMBRANES, THE PHYSIOLOGICAL MODELING OF THE DISTRI ...

THE LACK OF EFFICIENT TOOLS TO IDENTIFY GENOTYPES OF SUPERIOR WATER-USE EFFICIENCY (WUE) HAS LED TO LITTLE PRACTICAL SUCCESS IN IMPROVING CROPS WITH REGARD TO THIS VERY IMPORTANT TRAIT. HOWEVER, STABLE CARBON ISOTOPE ( (13)C) ANALYSIS IS PRESENTLY EMERGING AS A POTENTIALLY HIGHLY EFFICIENT MEANS OF EVALUATING PLANTS FOR WUE, ALTHOUGH THE TECHNOLOGY HAS NOT YET BEEN APPLIED TO CROP DEVELOPMENT. IN ...

THIS PROPOSED PROJECT WILL PROVIDE RESEARCH ON A NOVEL APPROACH TO MICRO-COMPUTER TRANSLATION OF PRINT MATERIAL INTO BRAILLE AND BRAILLE TO PRINT. KNOWLEDGE AND EXPERIENCE ARE DERIVED FROM RAISED DOT COMPUTING'S PREVIOUS COMMERCIALLY SUCCESSFUL SOFTWARE DESIGN AND APPLICATIONS DEVELOPMENT FOR VISUALLY IMPAIRED COMPUTER APPLICATIONS. THE MERITS OF STRUCTURED PROGRAMMING LANGUAGE TRANSLATION AND FOR ...

TECHNICAL RESEARCH ASSOCIATES, INC. PROPOSES THE DEVELOPMENTOF A NOVEL PLATELET-HARVESTING SYSTEM BASED ON A PREVIOUSLY DEVELOPED ULTRASOUND SEPARATION TECHNOLOGY. THIS TECHNOLOGY, DEVELOPED UNDER AN NHLBI GRANT, ALLOWS THE SEQUENTIAL SEPARATION OF CELLS BASED ON THEIR SIZE, EVEN THOSE CELLS THAT HAVE IDENTICAL DENSITIES. FIRST, RESIDUAL ERYTHROCYTES AND LARGE LEUKOCYTES CAN BE SEPARATED FROM PLAT ...
