THE POSSIBILITY THAT ATOMIC CHLORINE CONCENTRATIONS IN THE MARINE SURFACE LAYER ARE LARGE ENOUGH TO COMPETE WITH OH AS THE MAJOR TROPOSPHERIC OXIDIZER HAS RECEIVED CONSIDERABLE SPECULATION. CHLORINE ATOMS PARTICIPATE IN THE OXIDATION OF HYDROCARBONS AND DIMETHYL SULFIDE AND CAN ALSO DIRECTLY INFLUENCE TROPOSPHERIC OZONE LOSS THROUGH CATALYTIC CYCLES WITH C1O AND HO2 RADICALS. THE NET EFFECT ON T ...

A HIGH SPEED, HIGH SENSITIVITY AVALANCHE PHOTODIODE (APD) ARRAY IS BEING INVESTIGATED TO MEET THE STRINGENT REQUIREMENTS OF DETECTORS FOR HIGH ENERGY PHYSICS EXPERIMENTS SUCH AS THE CENTRAL TRACKER VERTEX DETECTOR AND CALORIMETERS WHICH ARE BEING DESIGNED FOR EXISTING AND PROPOSED PARTICLE PHYSICS DETECTORS. THESE DETECTORS WILL HAVE UNPRECEDENTED PERFORMANCE CHARACTERISTICS TO BE USED AS READOUT ...

HIGH-TEMPERATURE SUPERCONDUCTOR (HTS) COMPOSITE WIRES ARE BEING STRENGTHENED USING INTERNALLY OXIDIZED, DISPERSION STRENGTHENED (ODS) SILVER. CURRENT METHODS OF MANUFACTURE OF STATE-OF-THE-ART HTS COMPOSITE WIRES THAT CONSIST OF CERAMIC SUPERCONDUCTOR FILAMENTS ENCASED IN A SILVER (AG) SHEATH, WEAKEN THE AG SHEATH, RESULTING IN REDUCED HTS COMPOSITE STRENGTHS. THE LOW STRENGTH OF THE COMPOSITE W ...

TOXIC EMISSIONS FROM MUNICIPAL AND INDUSTRIAL WASTE INCINERATORS REPRESENT A SIGNIFICANT ENVIRONMENTAL HAZARD IN THE UNITED STATES. THESE EMISSIONS CONTAIN TOXIC POLYAROMATIC HYDROCARBON COMPOUNDS SUCH AS POLYCHLORINATED DIBENZO-P-DIOXINS AND DIBENZOFURANS. CONCENTRATIONS OF THESE HYDROCARBONS MUST BE REDUCED BY A FACTOR OF 100. NEW HIGH TEMPERATURE (1500 DEGREES K) INCINERATORS COULD BE FABRICATE ...
