THIS PHASE I EFFORT WILL APPLY THEORETICAL METHODS BASED PRINCIPALLY ON CAGNIARD'S FORMALISM (PREVIOUSLY INCORPORATED BY US INTO OUR POWERFUL SWREF CODE), TO THE PROPAGATION AND FOCUSING, IN BOTH REFLECTIVE AND PHASED-ARRAY EQUIPMENT, OF SHOCK-WAVES PRODUCED BY UNDERWATER SPARKS. THE OBJECTIVE IS TO INVESTIGATE AND PROVIDE DESIGN DATA FOR LITHOTRIPSY EQUIPMENT IN WHICH FOCUSED SHOCK WAVES ARE USED ...

CONVENTIONAL ROCK CORE DRILLING AT GREAT DEPTHS IS EXTREMELY EXPENSIVE AND TIME CONSUMING. ITS MAJOR DRAWBACK IS THE REQUIRED LENGTH OF DRILL PIPE. THE SUSPENSION CORE DRILL IS SUPPORTED BY CONTINUOUS FLEXIBLE LEADS HELD ON ONE OR MORE HIGH-SPEED REELS. WITHDRAWALS AND REPLACEMENT TIMES CAN BE REDUCED BY AN ORDER-OF-MAGNITUDE. COMMERCIAL USES INCLUDE STANDARD CORING APPLICATIONS AS WELL AS INTERMI ...

RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

THE RECENT DEVELOPMENT OF MOLECULAR BIOLOGY, PARTICULARLY INTHE FIELD OF RECOMBINANT DNA TECHNOLOGY, GIVES BIRTH TO A NEW ERA IN MEDICAL THERAPEUTICS AND DIAGNOSTICS USING PRODUCTS FROM MAMMALIAN CELL CULTURE. FOR EFFECTIVE RESEARCH AND CLINICAL USE, THESE PRODUCTS NEED TO BE MANUFACTURED IN LARGE QUANTITIES AND AT A TOLERABLE COST. TODAY PRODUCTION COSTS ARE VERY HIGH. THIS PROPOSAL IS PARTOF AN ...
