A FAST, RELIABLE, QUANTITATIVE ALPHA PARTICLE DIAGNOSTIC MEASURING SYSTEM IS AN IMPORTANT COMPONENT IN BOTH THE NEAR TERM AND FUTURE MAGNETIC FUSION PROGRAM. BURNING PLASMA EXPERIMENTS IN THE TOKAMAK FUSION TEST REACTOR AND OTHER EXISTING TOKAMAKS, AND IGNITED PLASMA CONDITIONS IN THE COMPACT IGNITION TOKAMAK, ARE EXPECTED TO ESTABLISH THE ALPHA PARTICLE PHYSICS BASIS NEEDED FOR THE FUSION ENERGY ...

BLACK LIQUOR RECOVERY BOILERS EMPLOY BLACK LIQUOR AS A PRIMARY FUEL THAT CONTAINS LARGE AMOUNTS OF SODIUM CARBONATE, SODIUM SULFIDE, AND SMALL AMOUNTS OF SODIUM SULFATE. THE FUEL, AS INTRODUCED IN THE BOILER, CONTAINS APPROXIMATELY ONE-THIRD WATER, ONE-THIRD CHEMICALS, AND ONLYONE-THIRD COMBUSTIBLE MATERIALS. THE BLACK LIQUOR RECOVERY BOILER IS AN ESSENTIAL STEP OF THE KRAFT PULPING PROCESS FOR PR ...

THE ADVANCED TANDEM-PULSE COMBUSTION SYSTEM BEING STUDIED FOR DIRECT COAL FIRING IN COMBUSTION GAS TURBINES PROVIDES INCREASED COMBUSTION EFFICIENCY AT SHORTER RESIDENCE TIMES, AS WELL AS A VERY COMPACT OVERALL COMBUSTOR ISLAND SUBSYSTEM FOR SIMULTANEOUS CONTROL OF NO(X),S0(X) PARTICULATE, AND ALKALI EMISSIONS UPSTREAD OF THE TURBINE. THE COMBUSTOR ISLAND TECHNOLOGY CONSISTS OF TANDEM-PULSE COMBUS ...

PHASE I WILL USE A NOVEL GRAFTING TECHNIQUE TO MODIFY MEMBRANE MATERIALS SO AS TO ENHANCE THEIR PERMEATION GRAFTING APPROACH BY CONDUCTING STUDIES ON BOTH DENSE FILMS AND POROUS POLYMER MEMBRANES. FEASIBILITY WILL BE DEMONSTRATED BY GRAFTING CHARGED MONOMERS ONTO SEVERAL MATERIALS INCLUDING POLYSULFONE, CELLULOSE ACETATE, AND POLYAMIDE. SUCCESSFUL MEMBRANES WILL EXHIBIT ENHANCED REJECTION OF MULTI ...

RADIATION HARD PLASTIC SCINTILLATOR FIBERS ARE NEEDED FOR USE IN DETECTORS OF HIGH ENERGY PARTICLES AT THE SUPERCONDUCTING SUPER COLLIDER (SSC). A CLASS OF POLYMERS, POLYORGANOSILOXANES, CAN WITHSTAND RADIATION DOSES UP TO 18 M RAD WITH LITTLE OPTICAL DAMAGE. OTHER OPTICAL POLYMERSDISCOLOR UNDER THESE CONDITIONS. POLYORGANOSILOXANES ARE AVAILABLE COMMERCIALLY AS CROSS-LINKED ELASTOMERS. THEY CANNO ...

SPECIAL MILITARY NARROW BEAM ACOUSTIC PROJECTORS AND TRANSMISSION TECHNIQUES CAN BE EASILY ADAPTED FOR COMMERCIAL USE TO ENABLE FISHERMEN OR RESEARCHERS TO DETECT,LOCATE, AND QUANTIFY BIOLOGICAL TARGETS WITH VERY HIGH ACCURACY IN SHALLOW WATER. THE PROPOSED EFFORT WILL PROVIDE A METHOD FOR PRODUCING VERY NARROW ACOUSTIC BEAMS WITH VIRTUALLY NO SIDELOBES FROM A SMALL APERTURE PROJECTOR ARRAY. ALSO ...

THE RELATIONSHIPS BETWEEN SMALL-SCALE STRATIGRAPHY AND THE PERMEABILITY DISTRIBUTION IN ROCKS HAVE NOT BEEN ESTABLISHED. THIS PROJECT WILL BUILD A SYSTEMS DYNAMICS COMPUTER MODEL TO TEST THE RELATIVE IMPORTANCE OF SMALL- SCALE STRATIGRAPHY TO THE PERMEABILITY DISTRIBUTION IN A SANDSTONE CORE. PERMEABILITY CHANGES AS DIAGENETIC EVENTS CEMENT SAND INTO SANDSTONE; DIAGENETIC TEXTURES SUCH AS CEMENT D ...
