CERAMIC MEMBRANES ARE RAPIDLY EMERGING AS A NEW TECHNOLOGY IN MEMBRANE SEPARATIONS. HOWEVER, COMMERCIALLY-AVAILABLE DEVICES HAVE HIGH COSTS RELATIVE TO POLYMERIC MEMBRANES, TYPICALLY FIVE TO TEN TIMES HIGHER. THE TECHNOLOGY TO BE DEVELOPED EMPLOYS A UNIQUE APPROACH TO CERAMIC MEMBRANE MODULE DESIGN. THE MODULE CONCEPT SHOULD RESULT IN PRODUCTION OF CERAMIC MEMBRANES WITH A COST LESS THAN THOSE FOR ...

A NEW, RAPID AND SENSITIVE TEST METHOD FOR THE DETECTION OF ERYTHROMYCIN IN ANIMAL-DERIVED PRODUCTS SUCH AS MILK AND MEAT WILL BE DEVELOPED BASED ON IMMUNOASSAY METHODOLOGY. DIRECTED SYNTHETIC TECHNIQUES WILL BE USED TO PREPARE THE IMMUNOGENS NECESSARY TO DEVELOP ANTIBODIES, BOTH MONOCLONAL AND CONVENTIONAL, WITH THE BROADEST RECOGNITION FOR ALL DRUGS IN THE MACROLIDE CLASS OF ANTIBIOTICS AS WELL ...

SWINE PRODUCERS AND SWINE INDUSTRY CONSULTANTS MUST DETERMINE WHAT AREAS OF SWINE PRODUCTION ARE LEAST EFFICIENT ECONOMICALLY IN ORDER TO REGAIN PROFITABILITY. BYDEVELOPING AN INTEGRATED, DETAILED FINANCIAL/BIOLOGIC DATABASE, SWINE PRODUCERS WILL BE ABLE TO DETERMINE INEFFICIENCIES IN THEIR OWN BUSINESSES THROUGH ANALYSIS OF THEIR DATA, AND THEY WILL BE ABLE TO PLAN THE MOST EFFECTIVE SOLUTION BY ...

THIS RESEARCH PROJECT WILL DEMONSTRATE THE TECHNICAL AND ECONOMIC FEASIBILITY OF A MAGNETIC SEPARATOR FOR OPERATION ON PULVERIZED COAL. A THEORETICAL COMPARISON OF THE SEPARATOR WITH WORK PUBLISHED ON OPEN GRADIENT MAGNETIC SEPARATION BY THE OAK RIDGE NATIONAL LABORATORY INDICATES THAT THE SEPARATOR WILL HAVE HIGH LEVELS OF ASH CLEANING. THIS IS BECAUSE OF ITS COUNTERCURRENT PRINCIPLE OF OPERATION ...

THERE IS A NEED FOR AN INEXPENSIVE, COMPACT, LOW MAINTENANCE SUB-PICOSECOND OPTICAL PULSE SOURCE TO DRIVE AN OPTICALLY SAMPLED AND TRIGGERED OSCILLOSCOPE. ADEQUATE LASER SOURCES PRESENTLY OCCUPY TEN SQUARE FEET AND REQUIRE REGULAR MAINTENANCE, 20 KW OF ELECTRICITY, AND COOLING WATER; AND THEY COMPRISE THE MAIN COST ITEM IN THE PICOSECOND OSCILLOSCOPE. THE NEW PULSED LASER UNDER DEVELOPMENT IN THIS ...

ONE OF THE MOST ACTIVE AND CHALLENGING FIELDS IN MOLECULAR BIOLOGY TODAY IS THE GENETIC STUDY OF EUKARYOTIC SYSTEMS. THE PRELIMINARY, BUT OFTEN RATE LIMITING, STEPS IN THIS AREA ARE THE DNA TRANSFER/HYBRIDIZATION TECHNOLOGIES ASSOCIATED WITH GENE MAPPING, AND THE SCREENING OF DNA LIBRARIES FOR GENE ISOLATION. THESE PROCEDURES USE RADIOLABELED HYBRIDIZATION TECHNIQUES AND AUTORADIOGRAPHY TO ACHIEVE ...

PRESENTLY AVAILABLE MASS SPECTROMETER-BASED VACUUM INSTRUMENTS ARE NOT SUITABLE FOR USE IN ANTICIPATED FUSION FACILITIES, WHERE TRITIUM WILL BE USED. THE ION SOURCE IS THE PRIMARY LIMITATION. THIS R&D PROGRAM WILL LEAD TO DEVELOPMENT OF A MINIATURE ECR (ELECTRON CYCLOTRON RESONANT)MICROWAVE ION SOURCE FOR APPLICATION IN LEAK DETECTORS AND VACUUM INSTRUMENTATION. THE ECR ION SOURCE CAN BE DEVELOPED ...

THE UNIQUE PROPERTIES OF DIAMOND MAKE IT ATTRACTIVE AS A MATERIAL FOR USE IN HIGH FREQUENCY, HIGH POWER, MILLIMETER MICROWAVE TUBES AND TRANSMISSION LINES. RECENT ADVANCES IN GYROTRONS AND FREE ELECTRON LASERS (FELS) AS POWER SOURCES, AND EXCELLENT PHYSICS RESULTS FROM THE T-10 TOKAMAK IN THE U.S.S.R. AND BIG-D AT GA TECHNOLOGIES IN THE U.S., HAVE HAD A MAJOR IMPACT ON THE FUSION PROGRAM. AN EXPER ...
