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 ...

N/A

THIS RESEARCH WILL DEVELOP AN EXTENSIVE SET OF QUALITY METRICS FOR THE EVALUATION OF IDEF MODEL QUALITY, INPARTICULAR, AND FOR THE EVALUATION OF SYSTEMS ANALYSIS MODEL QUALITY, IN GENERAL. THE RESEARCH IS THE CONTINUATION OF INVESTIGATIONS ALREADY PERFORMED BY THE PRINCIPAL INVESTIGATOR, MR. WILLIAM R. WILLIAMSON, UNDER INTERNAL COMPANY FUNDING. THE SPECIFIC METHODOLOGY, IDEF, WAS CHOSEN FOR THE R ...

N/A

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 ...

GENERALLY, OXYGEN AFFINITY INCREASES AFTER TREATMENT OF HEMOGLOBIN S (HBS) WITH COVALENT ANTISICKLING AGENTS, SUCH AS IMIDOESTER CROSSLINKING REAGENTS. ADDING INOSITOL HEXAPHOSPHATE (IHP) DURING THE CROSSLINKING PROCEDURE WILL LOWER THE AFFINITY, PROTECT THE 2,3-DIPHOSPHOGLYCERATE BINDING SITE AND ULTIMATELY IMPROVE OXYGEN DELIVERY TO TISSUES. THE GOAL OF THIS PROJECT IS TO PRODUCE A STABLE HBS TH ...

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 ...

FIRST WALL PROTECTION MATERIALS FOR A FUSION REACTOR MUST BE ABLE TO WITHSTAND THE VERY HOSTILE THERMAL AND NUCLEAR ENVIRONMENT OF THE PLASMA CHAMBER. MATERIALS MUST HAVE HIGH THERMAL CONDUCTIVITY, HIGH RADIATION RESISTANCE, AND EXCELLENT THERMAL SHOCK RESISTANCE, AMONG OTHER PHYSICAL CHARACTERISTICS. WE ARE PROPOSING TO DEVELOP A NOVEL MATERIAL TO BE USED FOR FIRST WALL PROTECTION, LIMITER, OR DI ...

ALTHOUGH MOLYBDENUM DISILICIDE (MOSI2) EXHIBITS HIGH-TEMPERATURE CHEMICAL STABILITY AND HAS A MELTING POINT OF 2010 DEGREES CENTIGRADE, THE LACK OF ROOM-TEMPERATURE FRACTURE TOUGHNESS AND POOR HIGH-TEMPERATURE CREEP RESISTANCE HAVE SEVERELY LIMITED ITS STRUCTURAL APPLICATIONS. THEREFORE, IT IS DESIRED TO FABRICATE COMPOSITES USING MOSI2, AS THE MATRIX MATERIAL. UNLIKE THE CONVENTIONAL CVI PROCESS, ...
