A NUMBER OF LOW GRAVITY MATERIALS PROCESSING EXPERIMENTS SUCH AS CRYSTAL GROWTH STUDIES REQUIRE A SPECIALIZED OPTICAL SYSTEM CAPABLE OF FLOW VISUALIZATION. SEVERAL SUCH SYSTEMS HAVE BEEN BUILT FOR USE IN SPACE AND BALLISTIC AIRCRAFT FLIGHTS, INCLUDING SCHLIEREN SYSTEMS. HOWEVER, NO COLOR SCHLIEREN SYSTEM HAS BEEN DEVELOPED FOR THESE APPLICATIONS. A COLOR SCHLIEREN SYSTEM PRODUCES DATA MORE AMENABL ...

A CONSIDERABLE AMOUNT OF R & D WORK HAS BEEN DONE FOR THE WANKEL ROTARY ENGINE APPLICATION TO AUTOMOBILES, PLANES, ETC. RESULTING IN SIGNIFICANT PROGRESS. THE PERFORMANCE, RELIABILITY AND DURABILITY THAT THE WANKEL HAS DEMONSTRATED, HOWEVER, FALLS SHORT OF THE POPULAR DIESEL ENGINE. THE ADIABATIC, TURBOCOMPOUND CONCEPT THAT HAS BEEN DEMONSTRATED FOR THE DIESEL IS THOUGHT TO BE MORE BENEFICIAL TO T ...

MORE THAN 3 BILLION BARRELS OF OIL WERE PRODUCED IN THE UNITED STATES IN 1984. VAST QUANTITIES OF CON- TAMINATED OILFIELD WASTEWATERS ARE GENERATED AS A RESULT OF THIS OIL PRODUCTION-OFTEN MORE THAN 10 BARRELS OF WATER PER BARREL OF OIL. THE RECOVERY OF OIL FROM TAR SANDS ALSO IS RESPONSIBLE FOR GENERATING OILY WASTEWATERS. CONVENTIONAL METHODS FOR DISPOSING THIS WASTEWATER INCLUDE HAULING IT FROM ...

A SIGNIFICANT PROBLEM IN THE USE OF DOMESTIC COAL RESOURCES TO GENERATE POWER IS THE PRODUCTION OF SO2 IN POWER-PLANT STACK GASES FROM THE COMBUSTION OF SULFUR IN THE COAL. STATE-OF-THE-ART SO2 SCRUBBING TECHNOLOGY, CENTERED AROUND LIQUID/GAS CONTACTORS, IS EXPENSIVE AND HAS OPERATIONAL DRAWBACKS. A NEW TECH- NOLOGY TO BE STUDIED HERE RELIES ON USING SO2-PERMEABLE MEMBRANES TO REMOVE SO2 FROM STAC ...

AN ELECTROCHEMICAL INSTRUMENTATION SYSTEM WILL BE DESIGNED AND CONSTRUCTED TO DETERMINE ON COMMAND PLANT WATER STATUS BY MEANS OF CYCLIC VOLTAMMETRY AND/OR COULOSTATICS. THE APPROACH IS BASED ON THE CHANGE IN ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE DURING THE NORMAL IRRIGATION CYCLE. A THREE WINDOW MICROPROBE WILL BE FABRICATED ON A SILICON WAFER SUBSTRATE USING THE PLANAR TECHNIQUES CO ...

CURRENT LIFE-SUPPORT SYSTEMS FOR EXPERIMENTAL ANIMALS CANNOT BE USED FOR DEVELOPMENTAL STUDIES OF ANIMALS IN SPACE. AN INNOVATIVE APPROACH TO THE DESIGN OF AN ANIMAL DEVELOPMENT HABITAT, COMPATIBLE WITH THE MIDDECK LOCKERS OF THE SPACE SHUTTLE, IS BASED ON STUDIES OF NATURALLY-OCCURRING MATERNAL BURROWS OF RODENTS, SURFACE/VOLUME RATIOS OF DIFFERENT HABITAT CONFIGURATIONS, AND ANALYSIS OF PHYSIOLO ...

MEDICAL SCIENCE HAS PROGRESSED TO THE POINT THAT CATHETERS AND ANGIOSCOPES CAN BE USED FOR DIRECT VISUALIZATION OF THE INTERIOR SURFACES OF THE HEART AND CORONARIES. THE PRIMARY HINDRANCE TO FURTHER PROGRESS IN THIS FIELD IS THE LACK OF A MINIATURIZED ANGULATION SYSTEM. THE PROPOSED CONCEPT SUGGESTS THAT PROPRIETARY MATERIALS BE INCORPORATED INTO THE TIP OF A CATHETER OR ANGIOSCOPE TO MAKE THEM MA ...

FOR FUTURE LONG-TERM SPACE MISSIONS SPACECRAFT WATER RECYCLE SYSTEMS ARE NOW UNDER DEVELOPMENT. ONE WATER RECYCLE SYSTEM STUDIED BY NASA INCLUDES A REVERSE-OSMOSIS (RO) SUBSYSTEM THAT WILL PRODUCE REUSABLE WATER FROM WASH WATERS. THE CONCENTRATE FROM THE RO SUBSYSTEM WILL BE COMBINED WITH URINE AND DISTILLED TO RECOVER MORE WATER. THIS PROJECT WILL INVESTIGATE THE USE OF AN ADDITIONAL RO COMPONENT ...

WE PROPOSE TO DEVELOP THE APPLICATION OF NEW TWO DIMENSIONAL, STATE OF THE ART CHARGE COUPLED DEVICE (CCD) IMAGE DETECTORS TO THE PROBLEM OF ANALYSIS OF PROTEINS BY DIGITIZATION OF TWO DIMENSIONAL POLYACRYLAMIDE ELECTROPHORETIC GELS. LONG TERM SUCCESS OF THIS PROJECT WILL RESULT IN COMMERCIALIZATION OF A NEW PRODUCT LINE OF MEDICAL MACHINERY, MORE WIDESPREAD USE OF ELECTROPHORESIS IN A CLINICAL SE ...

THE LONG-TERM OBJECTIVE OF THE PROPOSED PROGRAM IS TO DEVELOP A CONTROLLED-RELEASE DISULFIRAM IMPLANT FOR USE IN THE TREATMENT OF ALCOHOLISM. SPECIFIC PHASE I GOALS ARE 1. TO DESIGN CANDIDATE SYSTEMS, BASED ON TARGET PERFORMANCE TO BE DETERMINED FROM A REVIEW OF PRIOR RESEARCH, 2. TO PREPARE A SERIES OF CANDIDATE SYSTEMS, AND 3. TO DETERMINE THE IN VITRO DRUG RELEASE FROM THESE CANDIDATES. THE PRO ...
