SELECTIVE NO REDUCTION TECHNIQUES INVOLVING THE INJECTION OFNITROGEN-CONTAINING COMPOUNDS, SUCH AS AMMONIA, TO COMBUSTION PRODUCTS OVER A RELATIVELY NARROW TEMPERATURE RANGE HAVE BEEN USED FOR SOME TIME. SYSTEMS HAVE BEEN INSTALLED ON GAS-, OIL-, AND COAL-FIRED BOILERS, ON PROCESS HEATERS, AND ON MUNICIPAL WASTE INCINERATORS. HOWEVER, THESE SYSTEMS ARE LIMITED IN THEIR CONTROL EFFECTIVENESS. THERM ...

IT IS PROPOSED THAT LEE SCIENTIFIC INVESTIGATES AND DEVELOPSNEW AND IMPROVED INSTRUMENTAL METHODS FOR THE ANALYSIS OF N NON-VOLATILE ORGANIC COMPOUNDS IN COMPLEX ENVIRONMENTAL MA MATRICES BY CAPILLARY COLUMN SUPERCRITICAL FLUID CHROMATO GRAPHY (SFC). NON-VOLATILE COMPOUNDS OF SPECIFIC INTEREST INCLUDE HEAVY-MOLECULAR-WEIGHT, POLAR, AND THERMAL-LABILE SPECIES WHICH HAVE PROVEN TO BE DIFFICULT OR IM ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

FUSION SYSTEMS HAS DEVELOPED A MERCURY-FREE, HIGH COLOR RENDERING, EFFICIENT LAMP USING PROPRIETARY BUT BENIGN LAMP FILLS. THEY PROPOSE TO INVESTIGATE VARIATIONS OF THE LAMP SYSTEM PARAMETERS WITH THE DUAL GIALS OF FURTHER INCREASING SYSTEM EFFICIENCY BY 1.5 X AND TO IMPROVE LAMP STARTING DOWN TO MINUS 40C. BOTH FACTORS ARE CRITICAL TOWARD ACHIEVING COMMERCIAL SUCCESS. THE NEW LAMP IS A MICROWAVE ...

THE PRINCIPAL SCOPE OF THE PROPOSED RESEARCH IS TO DEVELOP SOFTWARE FOR A BC-CONTROLLER WHOSE PURPOSE IS TO SUPPLY AND CONSTANTLY UPDATE THE BOUNDARY CONDITIONS (BC) TO AN ON-LINE PLANT ANALYZER, ENABLING IT TO FAITHFULLY TRACK A NUMBER OF THE CONTINUOUSLY MEASURED PLANT PARAMETERS. THE BC-CONTROLLER SAMPLES PLANT MEASUREMENTS FROM THE PLANT COMPUTER MEMORY. THE PLANT ANALYZER, IN TURN, PROVIDES D ...

THIS PROJECT IS AIMED AT DEVELOPING TECHNIQUES FOR PREDICTING CHECK VALVE PERFORMANCE AND ITS INTERNAL COMPONENTS DEGRADATION IN PRACTICAL PIPING SYSTEMS USED IN NUCLEAR POWER PLANTS. THE MAIN FOCUS OF THE EFFORT IS TO SYSTEMATICALLY EVALUATE THE EFFECT OF UPSTREAM DISTURBANCES WHICH ARE WITHIN 10 DIAMETERS UPSTREAM. BY USING A COMBINED THEORETICAL AND EXPERIMENTAL APPROACH, GENERALIZED NONDIMENSI ...
