AN ELECTROCHEMICAL INSTRUMENTATION SYSTEM WILL BE DESIGNED AND CONSTRUCTED TO DETERMINE ON COMMAND PLANT WATER STATUS BY MEANS OF CYCLIC VOLTAMMETRY AND/OR COULOSTATICS. THE APPROACH IS BASED ON THE CHANGE IN ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE DURING THE NORMAL IRRIGATION CYCLE. A THREE WINDOW MICROPROBE WILL BE FABRICATED ON A SILICON WAFER SUBSTRATE USING THE PLANAR TECHNIQUES CO ...

CRYOCOOLERS AND GAS LIQUEFIERS UTILIZE ISENTHALPIC EXPANSION OF COOLED GAS IN JOULE-THOMSON NOZZLES. TO EFFECTIVELY OPTIMIZE USAGE OF THE COMPRESSED GAS, A VARIABLE GAS MASS FLOW RATE IS NECESSARY. A HIGH FLOW RATE IS REQUIRED INITIALLY WITH A PROGRESSIVE REDUCTION AS THE DESIGN CONDITION IS ATTAINED AND INTERMITTENT FLOW THEREAFTER DEPENDING ON THE LOAD DEMAND. THIS PROJECT INCORPORATES INNOVATIV ...

THE PRESENT PROCESS OF PRODUCING INTERMETALLIC ALLOY POWDER BY MELTING, CASTING, AND A POWDER ATOMIZA- TION STEP IS EXPENSIVE AND TECHNICALLY LACKING, THUS LIMITING THE ULTIMATE MECHANICAL AND PHYSICAL PRO- PERTIES OF THE INTERMETALLIC MATERIAL. THIS PROJECT EX- AMINES THE FEASIBILITY OF PRODUCING NICKEL AND TITA- NIUM ALUMINIDE INTERMETALLIC ALLOY POWDER BY THE DIRECT REDUCTION OF METAL CHLORIDE ...

A PROPOSAL IS PRESENTED OUTLINING A RESEARCH STUDY DIRECTED TOWARD TREATMENT OF CHEMICAL MILLING WASTE FOR RECOVERY OF COBALT, CHROMIUM, AND NICKEL. THE APPLICATION OF A NEW TECH NOLOGY IS PROPOSED THAT IS SELECTIVE AND COST EFFECTIVE FOR RECOVERY OF THESE THREE ELEMENTS. THE PROCESS IS ON OF SOL SOLUTION PURIFICATION BY SELECTIVE PHOSPHATE PRECIPITATION. THE PRECIPITATION IS SELECTIVE TOWARD TRIV ...

SAILCOMP INDUSTRIES PROPOSES TO DESIGN AN ACOUSTIC DOPPLER WIND VELOCITY AND DIRECTION SENSING SYSTEM THAT OVERCOMES THE PROBLEM ASSOCIATED WITH PRESENT MECHANICAL DESIGNS. THE ACOUSTIC VELOCIMETER SYSTEM WILL CONSIST OF FOUR PAIRS OF TRANSDUCERS IN FEEDBACK LOOPS. BY MEASURING THE DOPPLER PHASE SHIFT IN EACH OF THE FOUR LEGS OF THE SYSTEM, WIND VELOCITY AND DIRECTION CAN BE CALCULATED. THIS SOLID ...

A NUMBER OF LOW GRAVITY MATERIALS PROCESSING EXPERIMENTS SUCH AS CRYSTAL GROWTH STUDIES REQUIRE A SPECIALIZED OPTICAL SYSTEM CAPABLE OF FLOW VISUALIZATION. SEVERAL SUCH SYSTEMS HAVE BEEN BUILT FOR USE IN SPACE AND BALLISTIC AIRCRAFT FLIGHTS, INCLUDING SCHLIEREN SYSTEMS. HOWEVER, NO COLOR SCHLIEREN SYSTEM HAS BEEN DEVELOPED FOR THESE APPLICATIONS. A COLOR SCHLIEREN SYSTEM PRODUCES DATA MORE AMENABL ...

WE PROPOSE TO DEVELOP THE APPLICATION OF NEW TWO DIMENSIONAL, STATE OF THE ART CHARGE COUPLED DEVICE (CCD) IMAGE DETECTORS TO THE PROBLEM OF ANALYSIS OF PROTEINS BY DIGITIZATION OF TWO DIMENSIONAL POLYACRYLAMIDE ELECTROPHORETIC GELS. LONG TERM SUCCESS OF THIS PROJECT WILL RESULT IN COMMERCIALIZATION OF A NEW PRODUCT LINE OF MEDICAL MACHINERY, MORE WIDESPREAD USE OF ELECTROPHORESIS IN A CLINICAL SE ...
