THE PROJECT WILL DEVELOP A NOVEL MINIATURE PULSE WIDTH MODULATED POWER DRIVER FOR ACTUATORS, I.E. DC MOTOR. THE POWER DRIVER WILL DELIVER 50 AT 50VDO IN A DOUBLE INON PACKAGE. THIS COMPACT DESIGN CAN ONLY BE ACHIEVED THROUGH THE INNOVATIVE COMBINATION OF MODER POWER SEMICONDUCTOR TECHNOLOGIES, PROPRIETORY CIRCUIT DESIGN, AND STATE-OF-THE-ART PACKAGING TECHNOLOGY WHICH UTILIZES NEW HEAT CONDUCTIVE ...

BIOLOGICAL AND HAZARDOUS SLUDGES AND SLURRIES REPRESENT A MAJOR DISPOSAL PROBLEM. DEWATERING IS A MAJOR COST ELEMENT. THIS TWO-STEP TECHNOLOGY INVOLVES A FIRST STEP ACHIEVING ESSENTIALLY COMPLETE DEWATERING IN A BACKMIX REACTOR BY DISPERSION OF SLUDGE IN HEAVY OIL REACTION MEDIA MAINTAINED AT WATER VAPORIZATION TEMPERATURE USING ENERGY EFFICIENT VAPOR RECOMPRESSION. THE OXIDIZABLE IN THE VAPOR PHA ...

APPLICATION OF BIOTECHNOLOGY TO THE PRODUCTION OF 4-HYDROXYBENZOCYCLOBUTENE WILL ALLOW BULK MANUFACTURE OF THIS POLYMER PRECURSOR BY MORE ECONOMICAL MEANS THAN IS CURRENTLY AVAILABLE. DEVELOPMENT OF SUCH A PROCESS WOULD ALLOW INDUSTRIAL APPLICATIONS OF BCB-BASED POLYMER MATERIALS.

BECAUSE BACTERIAL DISEASES ARE FREQUENTLY TRANSMITTED THROUGH CONTAMINATED WATER, THE DETECTION OF MICROBIOLOGICALCONTAMINATION IS IMPORTANT, TO ENSURE SANITARY WATER SUPPLIES. CURRENT TESTS ARE LABOR INTENSIVE AND TAKE SEVERAL DAYS TO CONFIRM CONTAMINATION LEVELS. THIS PROJECT WILL DEMONSTRATE THE FEASIBILITY OF A UNIQUE, RAPID, WATER-QUALITY TEST FOR BACTERIA. PHASE I FOCUSES ON THE DEVELOPMENT ...

TAMM RELATES TO TWO TECHNOLOGIES FOR NONINVASIVE TRANSCUTANEOUS MEASUREMENTS OF BLOOD ANALYTES THAT HAVE POTENTIAL FOR APPLICATION IN A COMBAT CASUALTY CARE ENVIRONMENT. THE NEAR INFRARED (NIR) REFLECTANCE TECHNOLOGY DETERMINES BLOOD ANALYTE CONCENTRATION BASED ON DIFFUSE REFLECTANCE MEASUREMENTS WITH A FIBER OPTIC PROBE. SPECTRAL DATA ACQUIRED IS PROCESSED USING SOPHISTICATED PATTERN RECOGNITION ...

MICROBIOLOGICAL MONITORING WILL BE A CRITICAL FUNCTION IN THE BIOMASS-PROCESSING REACTORS OF THE NASA CONTROLLED ECOLOGICAL LIFE SUPPORT SYSTEM (CELSS). MEASUREMENT OF CELLDENSITY AND CELL ACTIVITY IN SOME REACTORS WILL ALLOW FOR THE AUTOMATION AND OPTIMIZATION OF BIOCHEMICAL PROCESSES WITHOUT THE NEED FOR EXPERIENCED SKILLED PERSONNEL. IN OTHER REACTORS, MICROBIOLOGICAL DETECTION AND CHARACTERIZA ...

THE OBJECTIVE IS TO DEVELOP A VOLUME COIL FOR MULTI-FREQUENCY MR SPECTROSCOPY OF THE HUMAN BRAIN. THIS DEVELOPMENT IS EXPECTED TO SUBSTANTIALLY AID CLINICAL SPECTROSCOPIC RESEARCH IN PROVIDING A NON-INVASIVE METHOD OF MONITORING BIOCHEMISTRY AND PHYSIOLOGY IN A LESION. SIGNIFICANT IMPROVEMENTS ARE EXPECTED IN SENSITIVITY, UNIFORMITY, AND APPLICATION FEATURES OVER EXISTING COMMERCIAL PRODUCTS. THES ...

Oxide coatings previously developed to protect polyimide and carbon/carbon composites in low earth orbit are brittle and crack upon flexing. Adding small amounts of polytetrafluoroethylene (PTFE) increases coating flexibility but reduces atomic oxygen (AO) resistance and mechanicall durability. Coatings developed in this project will use inorganics with potentially greater flexibility (such as she ...

THE RESEARCH WOULD INVESTIGATE THE FEASIBILITY OF A METHOD FOR DIRECT ISOLATION AND CLONING OF GENES ASSOCIATED WITH STATES OF DISEASE, CELL DIFFERENTIATION, OR METABOLIC INDUCTION. PHASE I STUDIES WILL FOCUS ON STEPS IN THE PROCESS THAT CURRENTLY LIMIT THE WIDESPREAD USE OF SUBTRACTIVE NUCLEIC ACID HYBRIDIZATION AS A MEANS OF ISOLATING THE TARGET GENES. IN PHASE II THIS TECHNOLOGY WILL BE INTEGRA ...
