IT IS PROPOSED TO DEVELOP AND EMPLOY TWO ADVANCED TECHNOLOGICAL TOOLS IN THE CONTINUING R&D PROBLEM TO DEVELOP IMPROVED TUNGSTEN BASED COMPOSITE MATERIALS TO BE USED IN KINETIC ENERGY PENETRATORS: (1) THE HOT ISOSTATIC PRESSING (HIP) PROCESS WILL BE EMPLOYED TO FABRICATE THE MOST PROMISING TUNGSTEN-CERAMIC (CERMET) MATERIAL COMBINATIONS. (2) IN ORDER TO OBTAIN DYNAMIC MATERIAL PROPERTIES AND ULTIM ...

A NOVEL EMISSION CONTROL PROCESS FOR CHLORINATED HYDROCARBONS PRODUCES NO TOXIC OR CORROSIVE SECONDARY GASES. CATALYTIC ADSORBENT MATERIALS WILL BE DEVELOPED TO DESTROY LOW CONCENTRATIONS OF CHLORINATED HYDROCARBON IN GASEOUS EFFLUENTS WITHOUT THE RELEASE OF HYDROCHLORIC ACID AND CHLORINE GAS. INSTEAD THE ADSORBENT WILL FIX THE CHLORINE ATOMS AS HARMLESS NONVOLATILE CHLORIDE SALT AT TEMPERATURES W ...

THIS PROJECT IS PART OF A LONGER TERM EFFORT TO DEVELOP A COMMERCIAL PRODUCT TO ALLOW LARYNGECTOMEES TO REGAIN FULLY NATURAL SPEECH WITH THE SHORTEST REHABILITATION TIME. THE EFFORT TO DATE HAS PRODUCED HARDWARE REPLICATING THE LARYNX FUNCTION IN SPEECH WITH A GOOD QUALITY OF NATURALNESS. THIS PROJECT WILL DETERMINE THE FEASIBILITY OF IMPROVING THE LARYNGECTOMEE'S CONTROL OF THE NEW ARTIFICIAL LAR ...

A NEW CONCEPT IS DESCRIBED IN WHICH AN ALTERNATING MAGNETIC FIELD IS USED TO INDUCE A "SWEEPING" ELECTRIC FIELD WITH ADJUSTABLE "SWEEP ANGLE" AND "FREQUENCY" FOR GEL ELECTROPHORESIS. THE EASILY ADJUSTABLE SWEEP ANGLE AND FREQUENCY ARE KNOWN TO BE KEY FACTORS IN RESOLUTION OF ELECTROPHORESIS SYSTEMS AND A CLEAR ADVANTAGE TO EXISTING SYSTEMS. IN ADDITION, THE ADJUSTABLE PARAMETERS OF THE SYSTEM WILL ...

WE ARE DEVELOPING A WEARABLE, PERSONAL ELECTRONIC REMINDING,GUIDING AND LOCATION MONITORING SYSTEM THAT MAY BE USED TO AUGMENT TRADITIONAL TEACHING AND SUPERVISION OF STUDENTS WHOARE MENTALLY RETARDED AND/OR TO SERVE AS A LONG TERM COGNITIVE PROSTHETIC TO PROMOTE THEIR PERSONAL AUTONOMY. THIS WALKMAN-SIZED, MICROPROCESSOR-BASED GUIDANCE SYSTEM CANAUTOMATICALLY VERBALLY REMIND A USER ABOUT PRESCHED ...

THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO DEMONSTRATE THE FEASIBILITY OF UTILIZING A NEWLY DEVELOPED MICROPOROUS MATERIAL FOR VASCULAR PROSTHETIC APPLICATIONS, AND ALSO TO STUDY THE VARIOUS PROCESS PARAMETERS AND THEIR EFFECT ON THE PHYSICAL PROPERTIES OF THE END PRODUCT. AN INTERPENETRATING POLYMER NETWORK ("IPN") OF POLYTETRAFLUOROETHYLENE ("PTFE") AND POLYDIMETHYLSILOXANE ("PDMS") IS EXPANDE ...

THE OBJECTIVE OF THIS PROGRAM WILL BE TO USE AQUEOUS POLYMER TWO-PHASE SYSTEMS FOR THE PURIFICATION OF PROTEIN C FROM HUMAN PLASMA. BOTH PHASES CONTAIN GREATER THAN 80 PERCENT WATER WITH THE UPPER PHASE RICH IN POLYETHYLENE GLYCOL (PEG) AND THE LOWER PHASE RICH IN A POLYMER OR SALT. THE EXPERIMENTAL PROCEDURE WILL BE AIMED AT EXTRACTING PROTEIN C INTO THE TOP PHASE OF AN AQUEOUS TWO-PHASE SYSTEM T ...

THIS PROPOSAL ADDRESSES SUBTOPIC 1.D, "DEVELOPMENT OF SELF- INSTRUCTIONAL MODULES, EQUIPMENT, OR SOFTWARE THAT CAN BE USED TO TRAIN COURT STENOGRAPHERS TO DO REAL-TIME CAPTIONING." REAL-TIME CAPTIONING BASED ON COMPUTER-AIDED TRANSCRIPTION (CAT) EQUIPMENT HAS BEEN A MAJOR ADVANCE IN CAPTIONING SERVICES FOR HEARING IMPAIRED PEOPLE. HOWEVER, CAPTIONING AGENCIES ARE CURRENTLY HAVING DIFFICULTY FINDIN ...

THIS PROGRAM'S OBJECTIVE IS TO ESTABLISH THE RELAXOR FERROELECTRIC PB(MG1/2NBS/3)O3 (PMN) AS THE MATERIAL OF CHOICE FOR THIN FILM CAPACITORS IN DRAM AND ELECTRONIC PACKAGING APPLICATIONS.IN CONTRAST TO "NORMAL" FERROELECTRICS, E.G., BATIO3 AND PZT, RELAXORS OFFER HIGH DIELECTRIC CONSTANTS (K>10,000), BROAD PHASE TRANSITIONS,LOW E-FIELD DEPENDENCY OF K, AND LARGE RXC TIME CONSTANTS. IN ADDITION, TH ...
