RECENTLY CONCEIVED RADIATION TRANSPORT ANALYSIS TECHNIQUES WILL BE STUDIED TO ASSESS THEIR USE IN SPACE NUCLEAR POWER SHIELD DESIGN OPTIMIZATION. THE ULTIMATE AIM IS TO DETERMINE OPTIMAL COMPOSITIONS AND CONFIGURATIONS OF SHIELD COMPONENTS FOR THE PRO- TECTION OF SPACE SYSTEMS AGAINST MIXED RADIATION FIELDS FROM INTERNAL AND EXTERNAL SOURCES. PARTICULAR ATTENTION WILL BE PAID TO USING COMPOSITE AN ...

THIS PROJECT WILL STUDY THE REMOVAL OF SOX FROM COM- BUSTION PROCESS FLUE GASES FOLLOWED BY DIRECT CONVERSION TO ELEMENTAL SULFUR, USING CHELATED IRON THAT HAS BEEN REDUCED TO FORM A CHELATE:FES COMPLEX. THE PROCESS WOULD HAVE SALEABLE ELEMENTAL SULFUR AS THE ONLY SIGNIFICANT BYPRODUCT AND WOULD OPERATE WITH THE CHELATED IRON AS A REGENERABLE CATALYTIC REAGENT. THE REACTIONS TO BE EXAMINED IN THIS ...

PREVIOUS RESEARCH HAS INDICATED THAT THE THERMOPHILLIC BACTERIA, SULFOLOBUS ACIDOCALDARIUS, AND POSSIBLY RELATED VARIANTS, CAN REMOVE 75% OF THE SULFUR PRESENT IN HIGH-SULFUR COAL IN 3 TO 4 DAYS USING ELEVATED TEMPERATURES AND ACID CONDITIONS. THIS RESEARCH PROGRAM WILL DETERMINE, USING A BENCH-SCALE, FED-BATCH SYSTEM, THE RATE AND EFFICIENCY OF SULFOLOBUS DESULFURIZATION ON AQUEOUS COAL SLURRIES. ...

THE COUNTER CURRENT SOLID STREAMS HEAT TRANSFER (CCSSHT) RETORT IS A NEW PROCESS FOR EFFICIENT OIL RECOVERY FROM OUR PLENTIFUL TAR SANDS AND OIL SHALE RESERVES. AS A HEAT RECOVERY SOIL INCINERATOR, IT HAS THE ADVANTAGES OF REDUCED FUEL DEMAND AND LOW COMBUSTION GAS PRODUCT (REDUCING AIR POLLUTION CONTROL NEEDS FOR THE INCINERATOR). THE CCSSHT UNIT IS A SINGLE VESSEL ROTATING KILN THAT (1) PREHEATS ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A NEW CLASS OF BIOSENSORS BASED ON THE USE OF COLLOIDAL GOLD DIRECTLY OR DEPOSITED AS A POROUS GOLD FILM. THE KEY TO THE APPROACH ISTHE IMMOBILIZATION OF ENZYMES ON GOLD SURFACES THAT PROVIDE FOR HIGHFLUX, HETEROGENEOUS ELECTRON TRANSFER. THE FEASIBILITY OF CONSTRUCTING THIS NEW CLASS OF BIOSENSORS WILL BE EVALUATED BY THE END OF PHASE I. THE OBJECTIVES ...

THE SENSITIVITY OF NUCLEAR TRACK-RECORDING PLASTICS MAY BE MODIFIED BY MOLECULAR DESIGN. SUBSTITUTION OF GROUPS ADJACENT TO RADIATION-SENSITIVE BONDS AND INTRODUCTION OF NEW CENTRES OF INSTABILITY SHOULD GREATLY INCREASE THE SENSITIVITY TO IONIZING RADIATION. MODIFICATION TO THE CR-39 MONOMER WILL BE CONSIDERED BECAUSE THE POLYMER PRODUCED FROM IT IS BY FAR THE BEST PLASTIC TRACK DETECTOR YET DISC ...

A PROBLEM EXISTS IN DRYING HEAT-SENSITIVE DRUGS DURING THEIR BULK CHEMICAL PRODUCTION. THE PRESENTLY AVAILABLE EQUIPMENT IS BASED ON CONDUCTION AS THE PRIMARY HEAT- TRANSFER METHOD; HOWEVER, IN DRYING HEAT-SENSITIVE CHEMICALS, THE JACKET TEMPERATURE OF CURRENT PROCESS EQUIPMENT MUST BE REDUCED TO AVOID THERMAL DEGRADATION OF THE DRUG. THE REDUCTION OF CONDUCTIVE DRIVING FORCE RESULTS IN DECREASED ...

BECAUSE OF THE RAPIDLY INCREASING DEMANDS ON DATA ACQUISITION AND COMPUTER PROCESSING SYSTEMS IN MOST DOE-FUNDED RESEARCH TODAY, FASTBUS HAS BECOME A VITAL PRESENCE IN HIGH-ENERGY PHYSICS PROJECTS WORLDWIDE. SIMILARLY, BECAUSE OF ITS BROAD FLEXIBILITY AND INTERNATIONAL CHARACTER, VMEBUS IS EMERGING AS A POPULAR HOST AND POST-PROCESSING ENVIRONMENT. ALTHOUGH SOME SYSTEMSHAVE BEEN DESIGNED THAT ALLO ...
