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 PROPOSED PROGRAM OFFERS AN INNOVATIVE APPROACH FOR PROTECTING A BATTLE GROUP FROM ATTACKS BY ADVANCED ANTI-SHIP MISSILES. SPACIALLY DISTRIBUTED COUNTERMEASURES, OF VARIOUS TYPES, ARE DEPLOYED IN A COORDINATED MANNER SO AS TO COUNTER ALL PHASES AND ASPECTS OF THREAT MISSILE WEAPON SYSTEMS. THESE COORDINATED COUNTERMEASURES TECHNIQUES ARE APPLIED SEQUENTUALLY AND THEIR EFFECTIVENESS AGAINST EACH ...

OPTICAL DESIGN STUDIES WILL BE CARRIED OUT TO DEVISE AN OPTICS MODULE FOR FLOW CYTOMETRY SUCH THAT THE FLOW CHAMBER BECOMES AN INTEGRAL PART OF THE OPTICAL SYSTEM AND FLUOR- ESCENCE IS COLLECTED FOR ALMOST A FULL 4 STERIDIANS (DUAL- HEMISPHERICAL SPACE). AN IMPROVEMENT OF AT LEAST A FACTOR OF FOUR IN THE EFFICIENCY OF LIGHT COLLECTION OVER EXISTING DESIGNS AND BY MORE THAN AN ORDER OF MAGNITUDE OV ...

RECENT INFORMATION SUGGESTS THAT THE MEXICAN HISPANIC POPU- LATION IN THE UNITED STATES IS AT HIGH RISK FOR CORONARY HEART DISEASE, DIABETES MELLITUS, AND SOME SITE-SPECIFIC FORMS OF CANCER. OTHER DATA INDICATE THAT SOCIOCULTURAL FACTORS MAY PLAY A PRIMARY ROLE IN DETERMINING THE HEALTH STATUS OF THIS POPULATION. THE MOST IMPORTANT FACTORS IMPLICATED ARE DIET-RELATED KNOWLEDGE, ATTITUDES, AND BEHA ...

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 ...

ENORMOUS AMOUNTS OF LIGNOCELLULOSE ARE WASTED BUT THE ECONOMY OF PREPARING IT FOR INDUSTRIAL USE HAS HITHERTO PREVENTED DEVELOPMENT. CHEMICAL AND MECHANICAL LIGNINOLYTICMETHODS TEND TO BE ENERGY INTENSIVE AND/OR ARE ECOLOGICALLY UNDESIRABLE. MANY LIGNIN DEGRADING WHITE ROT BASIDIOMYCETESARE KNOWN, BUT PRODUCTION ON A LARGE SCALE HAS BEEN HAMPEREDBY SOME UNUSUAL OXYGEN REQUIREMENTS AND A SLOW REACT ...
