IRON AND SULFUR BACTERIA ARE PRINCIPAL CAUSES OF BIO FOULING OF WELL SCREENS, PUMPS, TREATMENT AND PROCESSING EQUIPMENT, AND IN EXTREME CASES, DISTRIBUTION SYSTEMS. ASSOCIATED PROBLEMS ARE HIGH-PUMPING COST, RAPID PUMP AND VALVE DETERIORATION, CORROSION OF ALL FERROUS MATERIAL IN CONTACT WITH THE WATER, INCREASED DISEASE RISK (SHIELDING, NURTURING MEDIA), AND BAD TASTE ODOR AND COLOR. THE PROBLEM ...

THE PRIMARY OBJECTIVE OF THIS RESEARCH IS TO DEVELOP NEW ANDIMPROVED BIOCOMPATIBLE RESTORATIVE RESINS FOR USE IN DENTISTRY. THE STRATEGY FOR ACHIEVING THIS OBJECTIVE IS TOTAILOR-MAKE LIQUID, HIGH-MOLECULAR WEIGHT POLYMERS THAT CAN BE CROSSLINKED WITH MINIMAL SHRINKAGE TO HARD, OPTICALLY TRANSPARENT COATINGS WITH GOOD ADHESION TO ENAMEL, DENTIN, AND GLASS FILLERS. GUMBS WILL DESIGN AND SYNTHESIZE L ...

A MILITARY SITUATION INVOLVING THE THREAT OF NUCLEAR WARFARE MAY REQUIRE RAPID DEPLOYMENT OF EQUIPMENT AND FACILITIES WHICH MAY REQUIRE SHIELDING AGAINST ELECTROMAGNETIC EFFECTS. THIS PROPOSAL IS TO EVALUATE THE FEASIBILITY OF A RAPIDLY DEPLOYABLE SHIELDING BLANKET SYSTEM THAT COULD BE QUICKLY ASSEMBLED IN THE FIELD FOR PROTECTION OF PERSONNEL AND EQUIPMENT. THE BLANKET WOULD CONSIST OF METAL COAT ...

IN THE THREE DAY PERIOD AFTER ONSET OF SYMPTOMS, SERIAL DETERMINATIONS OF BLOOD SERUM CPK AND LDH ISOENZYMES REMAIN THE BEST LABORATORY AID FOR EARLY DIAGNOSIS OF ACUTE MYO- CARDIAL INFARCTION. THE PHASE I GOAL IS TO DEVELOP A RAPID,COST-EFFECTIVE, HIGH-PRECISION, DIAGNOSTIC ISOENZYME TEST UTILIZING HABER'S ADVANCED SEPARATION TECHNOLOGY, ELECTRO- MOLECULAR PROPULSION (EMP). IN THIS STUDY, DIFFERE ...

THE GOAL OF THIS PROJECT IS TO DEVELOP AN IMPROVED METHOD FOR THE UTILIZATION OF DNA PROBES. CURRENT METHODS ARE COMPLEX AND EXPENSIVE AND THUS NOT SUITABLE FOR MANY APPLICATIONS IN CLINICAL AND GENERAL LABORATORIES, IN FIELD APPLICATIONS, OR IN THIRD-WORLD COUNTRIES. IN PHASE I, THE FEASIBILITY OF USING SINGLE STRANDED DNA PROBES AND A TRANSITION METAL CATALYST DETECTION SYSTEM WILL BE EXAMINED.T ...

HISTORICAL FAILURE DATA SHOW SOME SIXTY PERCENT OF INTEGRATED CIRCUIT FAILURES CAN BE TRACED TO INADEQUATE PROVISION FOR HEAT DISSIPATION. IMPROVING AVIONICS RELIABILITY REQUIRES FINDING REGIONS OF UNDUE THERMAL RESISTANCE IN THE COOLING AIR PATH FROM THE DEDICATED VAPOR CYCLE ENVIRONMENTAL CONTROL SYSTEM THROUGH SUPPLY DUCTING, RACK, SHELF, CAGE, CARD TO COMPONENT CASE. THE IMPERATIVE IS CONTROL ...

N/A

RESEARCH IS PROPOSED TO DETERMINE THE FEASIBILITY OF MAKING A NOVEL NON-METALLIC, DIMENSIONALLY STABLE AND ELECTRICALLY EFFICIENT ANODE FOR USE IN A MEMBRANE ELECTROCHEMICAL PROCE PROCESS FOR TH ELECTRO-OCIDATION OF CHROMIUM III, IN PROCESSLIQUORS, TO USEABLE CHROMIUM VI COMPOUNDS. AN EFFICIENT ECONOMICAL ANODE WOULD MAKE POSSIBLE DEVELOPMENT AND COMMERCIAL USE OF AN ELECTROCHEMICAL PROCESS THAT C ...
