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 PRINCIPAL OBJECTIVES OF THIS PROPOSAL ARE (1) TO EVALUATE A NOVEL BACILLUS HOST-VECTOR SYSTEM FOR THE CLONINGAND EXPRESSION OF GENES SPECIFYING MICROBIAL INSECTICIDAL ACTIVITIES; AND (2) TO DETERMINE THE FEASIBILITY OF AN INTERGENIC CONJUGAL TRANSFER SYSTEM FOR MOBILIZING RECOMBINANT PLASMIDS BETWEEN A VARIETY OF GRAM-POSITIVE HOSTS. A DELTA-ENDOTOXIN GENE FROM A PROTOTYPE STRAIN OF BACILLUS T ...

ETCI WILL INVESTIGATE THE TECHNICAL FEASIBILITY OF USING A MIXED-LIQUID ELECTROSTATIC COALESCENCE METHOD FOR THE SEPARATION OF MICRONIZED PARTICLES OF DIFFERING SURFACE CHARACTERISTICS. THE PROPOSED METHOD USES EMULSIFIED WATER AS A GETTER SELECTIVE TO HYDROPHILIC PARTICLES SUSPENDED ALONG WITH HYDROPHOBIC PARTICLES IN ORGANIC LIQUIDS SUCH AS KEROSENE AND FUEL OIL. IN THE ELECTROCOALESCE PROCESS, ...

LOSSES RESULTING FROM GYPSY MOTH DEFOLIATION IN THE N NORTHEAST IN 1981 WERE $764,000,000. (USDA APHIS 1981). THIS PEST IS DISPENSING AT ABOUT 500,000 ACRES PER YEAR DESPITE LARGE SCALE CHEMICAL SPRAYING. THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE TH FEASIBILITY OF COMBINING THE RELEASE OF PARASITES, GLYPTAPANTELES FLAVICOXIS AND THE APPLICATION OF THE BIOLOGICAL INSECTICIDE,]I[_ BACILLUS THUR ...

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 ...

CHEMICALLY CONTAMINATED AIR IS TO BE PURIFIED AND/OR DETOXIFIED BY CATALYTIC OXIDATION IN AN INTEGRAL HEAT EXCHANGER AND REACTOR. THIS DEVICE OF A DOUBLE SPIRAL MADE BY WINDING TOGETHER TWO STRIPS OF METAL COATED WITH A CATALYST. ONE SPIRAL PASSAGE LEADS INTO THE CORE OF THE SPIRAL AND THE OTHER PASSAGE LEADS OUT. AN ELECTRICAL-RESISTANCE HEATER SUPPLIES ENERGY AT THE CORE OF THE SPIRAL. THE OUTFL ...

Under a Phase II program, DRS Scientific will build, test, and deliver a new type of Acousto-Optic Tuned Filter (AOTF) hyperspectral imager that is compact, rugged, and inexpensive, has no moving parts, and is fast and sensitive. It will cover 8-12 micron wavelength range with 10 wavenumber spectral resolution or finer, and will have micro-Flick sensitivity with a cooled camera, and

This Small Business Innovation Research Phase II project engages K-12 students in inquiry-based learning not only in STEM education but across the curriculum. The coming of the information age has mandated radical changes in the skills set required for 21st century. To teach these skills, as articulated in the Common Core Standards, teachers are expected to target students? ability to conduct shor ...
