RESEARCHERS ARE DEVELOPING NUCLEAR/PARTICLE DETECTORS USING NEW FAST HEAVY INORGANIC SCINTILLATORS. THESE MATERIALS ARE OF TWO CLASSES: (1) BRIGHT CERIUM-ACTIVATED CRYSTALS - YAP, GAO, AND GSO - WHICH COULD DISPLACE THALLIUM DOPED SODIUM AND CESIUM IODIDE IN CERTAIN APPLICATIONS. THE CURRENT YAP CRYSTALS (UP TO 50 X 50 X 10 MM(3) HAVE MEASURED EFFICIENCIES, RESOLUTIONS, BRIGHTNESSES, AND MECHANI ...

DIAMOND FILMS ARE CONTEMPLATED FOR USE IN OPTICAL SYSTEMS DUE TO THEIR INERT NATURE AND HENCE THEIR ABILITY TO PROTECT THE VITAL OPTICAL SYSTEMS FROM THE HARSH ENVIRONMENTS. POLYCRYSTALLINE DIAMOND FILMS PRODUCE SCATTERING CENTERS DUE TO THE DIFFERENT IMPURITIES, GRAIN SIZES AND ORIENTATIONS THAT ARE PRODUCED BY THE DIFFERENT DEPOSITION TECHNIQUES. A NOVEL POLISHING METHOD IS PROPOSEDFOR PROVIDING ...

CURRENT PROCESSES FOR MANUFACTURING SAPPHIRE INTRODUCE A NUMBER OF DEFECTS SUCH AS DIE MARKS AND GROWTH ARTIFACTS IN THE AS-GROWN SAPPHIRE BLANK. THUS, THESE MATERIALS NEED TO BE POLISHED PRIOR TO USE IN OPTICS. THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A HIGH-QUALITY, HIGH-SPEED, COST-EFFECTIVE TECHNIQUE FOR POLISHING SAPPHIRE BASED OPTICS. THE TWO METHODS CURRENTLY USED FOR POLISHING SAPPHI ...

FIELD TRACKING OF SMOKE AND OBSCURANT CLOUDS FROM FOREST FIRES OR VOLCANOES REQUIRES DETERMINATION OF THE TWO-DIMENSIONAL CLOUD EXTENT SHOWN IN VISIBLE IMAGES SCANNED FROM VARIOUS ANGLES ABOUT THE CLOUDS. AT THE PRESENT TIME, TWO-DIMENSIONAL CLOUD EXTENT IS DETERMINED BY AN OPERATOR WHO MANUALLY LOCATES POINTS ON THE CLOUD PERIMETER-A PROCEDURE WHICH HAS BEEN FOUND TO BE EXPENSIVE, TIME CONSUMING ...

THE POTENTIAL TO ACHIEVE HIGH INSULATING VALUE BY THE USE OF EVACUATED GLASS MICROSPHERES HAS BEEN KNOWN FOR SOME TIME. THE PURPOSE OF THE RESEARCH IS TO SOLVE THE PRINCIPAL OBSTACLE TO THEIR USE, WHICH HAS BEEN THE DEVELOPMENT OF A COMMERCIALLY VIABLE TECHNIQUE TO PRODUCE EVACUATED MICROSPHERES. IF HOLLOW GLASS MICROSPHERES CAN BE EVACUATED AND COATED COST-EFFECTIVELY, THEIR UTILITY AS INSULATI ...

NEOGEN IS COMMITTED TO DEVELOPMENT OF DIAGNOSTICS WHICH WILLIMPROVE THE HEALTH OF BOTH PLANTS AND ANIMALS. USING INFORMATION GATHERED FROM PRODUCTION OF ANTIBODIES WHICH RECOGNIZE VARIOUS MYCOTOXINS, SIMILAR PROCEDURES WOULD BE USED TO PRODUCE POLYCLONAL ANTISERUM IN RABBITS AND MONOCLONAL ANTIBODIES (SECRETED BY STABILIZED HYBRIDOMA CELLLINES) WHICH BIND TO SULFONAMIDES. THE INCORPORATION OF ANTI ...

AN ASSESSMENT IS PROPOSED OF CONTINUOUS HIGH-G CENTRIFUGA- TION FOR PRODUCTION PURIFICATION OF MEDICAL PROTEINS ARE SEPARATED TODAY IN ULTRA-CENTRIFUGES BUT IT IS NOT CONTINU- OUS AND THE METHOD HAS NOT BEEN ALL SCALED UP. THE SPECIFIC OBJECTIVES ARE TO ASSESS SEPARATION SELECTIVITY AND THROUGH PUT RATE; AND POSSIBLE BIOLOGICAL DAMAGE TO THE PROTEIN BY SHEAR BY SEDIMENTATION AND BY INTENSE CENTRIF ...
