A CONSIDERABLE AMOUNT OF R & D WORK HAS BEEN DONE FOR THE WANKEL ROTARY ENGINE APPLICATION TO AUTOMOBILES, PLANES, ETC. RESULTING IN SIGNIFICANT PROGRESS. THE PERFORMANCE, RELIABILITY AND DURABILITY THAT THE WANKEL HAS DEMONSTRATED, HOWEVER, FALLS SHORT OF THE POPULAR DIESEL ENGINE. THE ADIABATIC, TURBOCOMPOUND CONCEPT THAT HAS BEEN DEMONSTRATED FOR THE DIESEL IS THOUGHT TO BE MORE BENEFICIAL TO T ...

FABRICATION OF PROPELLANT TANKS INVOLVES COSTLY EXTENSIVE MACHINING OF THICK TI-6AL-4V FORGINGS. TWO PROMISING APPROACHES FOR TI-15V3CR-3SN AND HOT SUPERPLASTIC FORMING (SPF) OF TI-6AL-4V. SPF REQUIRES LOW FORMING PRESSURE, HAS EXCELLENT SHAPE CAPABILITY AND IS APPLICABLE TO WELL ESTABLISHED TI-6AL-4V. BUT, IT REQUIRES COSTLY TOOLING AND HEATING SYSTEMS. THE PROPOSED PROGRAM WILL INVESTIGATE A NOV ...

IN HYPERSONIC CRUISE, THE OUTER SURFACE OF A VEHICLE MADE OF A COMPOSITE MATERIAL ABLATES. THE ABLATED PARTICLES PENETRATE INTO THE BOUNDARY LAYER AFFECTING THE FLOW DYNAMICS AS WELL AS RADIATIVE AND CONVECTIVE HEAT TRANSFER TO AND FROM THE VEHICLE. THE AUTHORS PROPOSE TO PERFORM THEORETICAL ANALYSIS OF RADIATIVE AND CONVECTIVE HEAT TRANSFER IN A TURBULENT BOUNDARY LAYER OF HEAT RADIATION SCATTERI ...

AN ELECTROCHEMICAL INSTRUMENTATION SYSTEM WILL BE DESIGNED AND CONSTRUCTED TO DETERMINE ON COMMAND PLANT WATER STATUS BY MEANS OF CYCLIC VOLTAMMETRY AND/OR COULOSTATICS. THE APPROACH IS BASED ON THE CHANGE IN ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE DURING THE NORMAL IRRIGATION CYCLE. A THREE WINDOW MICROPROBE WILL BE FABRICATED ON A SILICON WAFER SUBSTRATE USING THE PLANAR TECHNIQUES CO ...

THE EFFECT OF THREE IMPORTANT PROCESS VARIABLES (ALTERING HEATING OF FEED LIQUID, CHAMBER LENGTH, AND CARRIER GAS TEMPERATURE) ON ENERGY NEEDED TO PRODUCE POTABLE WATER FROM WATERS CONTAINING DISSOLVED SOLIDS BY AN INNOVATIONAL MINIM UM ENERGY USING HEAT AND MASS TRANSFER DEVICE WILL BE INVESTIGATED. THIS DEVICE USES AN INERT CARRIER GAS OPERATING AT NEAR ATMOSPHERIC PRESSURE TO EVAPORATE WATER AN ...

GEOLOGIC MATERIAL PROPERTY REQUIREMENTS FOR NUMERICAL CALCULATION OF AN EXPLOSIVE EVENT DEPEND ON SEVERAL FACTORS, INCLUDING: THE PEAK PRESSURE EXPECTED OR ACHIEVED, THE GEOMETRY OF LOADING, AND THE TYPE OF CALCULATION BEING PERFORMED. ADDITIONALLY, THE CLASS OF GEOLOGIC MATERIAL INVOLVED; E.G., SAND VERSUS CLAY VERSUS ROCK, WILL DICTATE REQUIREMENTS BASED ON WHAT ARE ANTICIPATED TO BE THE IMPORTA ...

A PILOT SERIES OF THREE COMPUTER-INTERACTIVE VIDEODISK (CIVD) MODULES WILL BE DEVELOPED FOR TEACHING TOPICS IN TRANSFUSION MEDICINE (TM). THE CONTENT OF THE CIVD MODULES IS DETERMINED FROM THE NHLBI NATIONAL TM CURRICULUM AND INCORPORATES BOTH THE ETHICAL AND PSYCHOSOCIAL ISSUES INVOLVED IN THE PRACTICE OF TM. THE AUDIOVISUAL ELEMENT OF THE CIVD PACKAGES WILL BE SUPPLEMENTED BY APPROPRIATE WRITTEN ...

THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO PRODUCE A PORTABLE, MINIATURIZED DIALYSIS MACHINE WHICH IS SIMPLE, SAFE, AND SYMPTOM-FREE IN OPERATION. THIS DIALYSIS MACHINE SHOULD ALLOW THE AVERAGE HEMO-OR PERITONEAL DIALYSIS PATIENT TO PERFORM DIALYSIS BY HIMSELF AT HOME, UNASSISTED. THE MACHINE WILL BE SMALL (12 LBS.), PORTABLE, AND TOTALLY SELF-CONTAINED (WITHOUT NEED FOR CONNECTION TO WATER SUPP ...
