MANY UTILITY AND INDUSTRY COAL-FIRED BOILERS HAVE ELECTROSTATIC PRECIPITATORS (ESPS) ALONE, WHICH ARE NOT CAPABLE OF REMOVING SO2. MANY OLDER ESPS WILL REQUIRE UPGRADING IN THE 1990S TO MEET MORE STRINGENT PARTICULATE STANDARDS. ETS, INC. HAS TESTED ITS PATENTED LIMESTONE EMISSION CONTROL (LEC) SYSTEM, DEMONSTRATING GREATER THAN 90% SO2 REMOVAL CAPABILITY. LECS CAN BE PLACED DOWNSTREAM OF ESPS. IT ...

A PROGRAM IS PROPOSED TO SHOW THE FEASIBILITY OF DEPRESSED COLLECTORS FOR VERY HIGH AVERAGE POWER (APPROX. 1MW) GYROTRON OSCILLATORS FOR FUSION APPLICATIONS. INITIAL CALCULATIONS INDICATE THAT COLLECTION EFFICIENCIES EXCEEDING 75% CAN BE REALIZED. USE OF SUCH A COLECTOR ON A GYROTRON WITH A BASE EFFICIENCY OF 30% WOULD INCREASE THE EFFICIENCY TO OVER 60%. SUCH A DRAMATIC INCREASE IN EFFICIENCY WOU ...

BECAUSE OF THEIR LONG DECAY TIMES, SCINTILLATORS IN NEUTRON LOGGING TOOLS ARE RESPONSIVE PRIMARILY TO THE GAMMA RADIATION FROM THE NEUTRON CAPTURE SPECTUM. THIS INHIBITS POROSITY MEASUREMENTS IN GAS-FILLED ZONES AND SUBSTANTIALLY LIMITS THE ELEMENTAL INFORMATION ON THE STRATA WHICH CAN BE ACQUIRED. ADVANCES IN NEUTRON LOGGING TOOLS REQUIRE A NEW SCINTILLATOR MATERIAL CAPABLE OF MAKING PRECISION ME ...

WE DESCRIBE A NOVEL LEAK DETECTOR FOR XENON THAT HAS DIRECT APPLICATION TO TESTING RADIO-ISOTOPE-POWERED THERMOELECTRIC GENERATORS. SUCCESSFUL DEMONSTRATION OF OUR INNOVATION WILL ALLOW IMPROVED EFFICIENCY IN THERMOELECTRIC GENERATORS BY REMOVING THE HELIUM THAT IS NOW ADDED TO THE XENON BUFFERGAS FOR LEAK CHECKING PURPOSES. THE PHASE I RESEARCH PROGRAM WILL PROVIDE THE CRITICAL DESIGN INFORMATION ...

SURFACE METAL OXIDE AND OXYHYDROXIDE LAYERS HAVE BEEN IMPLICATED AS TRITIUM TRAPS IN STAINLESS STEELS. A NEW TECHNIQUE IS BEING DEVELOPED FOR MEASURING HYDROGEN ISOTOPE DIFFUSION WITHIN THIS LAYER AND WITHIN PERMEATION BARRIERS MEANT TO LIMIT TRITIUM INVENTORY IN THESE MATERIALS.

THE USE OF ADVANCED MATERIALS SUCH AS CERAMICS, CERAMIC COMPOSITES, AND HIGH TEMPERATURE COATINGS HAS LED TO IMPROVED PERFORMANCE OF CRITICAL HEAT ENGINE AND ENERGY-RELATED COMPONENTS AND SYSTEMS. HOWEVER, THE REQUIREMENTS FOR NONDESTRUCTIVE EVALUATION (NDE) OF CERAMIC MATERIALS RESULTING FROM COMPLEX GEOMETRY, INHOMOGENEITY, REDUCED FLAW SIZE, AND ADVERSE PROCESSING ENVIRONMENTS HAVE PRODUCED LON ...

THE PURPOSE OF THIS RESEARCH PROJECT IS TO GENERATE MONOCLONAL ANTIBODIES THAT RECOGNIZE DEFINED EPITOPES ON OLIGO- AND POLYSACCHARIDES OF PLANT ORIGIN. SUCH ANTIBODIESWILL BE USEFUL FOR PURIFYING PLANT-DERIVED OLIGO- AND POLYSACCHARIDES, PROVIDING STRUCTURAL INFORMATION ABOUT THE CARBOHYDRATES TO WHICH THE ANTIBODIES BIND, AND DETERMINING THE TISSUE AND CELLULAR DISTRIBUTION OF THE CARBOHYDRATES. ...
