ALTERED METABOLISM IN THE LUNG APPEARS TO BE AN EARLY EVENT IN ACUTE PULMONARY FAILURE SECONDARY TO ENDOTHELIAL CELL DAMAGE, AND MAY BE DETECTED BY AN INCREASE IN THE LEVEL OF FREE 5-HYDROXYTRYPTAMINE (5-HT) IN PULMONARY BLOOD. DIRECT AND UNAMBIGUOUS MEASUREMENT OF FREE BLOOD 5-HT LEVELS TO OBTAIN EARYL DIAGNOSIS OF PULMONARY DAMAGE WOULD BE POSSIBLEWITH ELECTROCHEMICAL METHODOLOGY IF AN ELECTRODE ...

THE STEREOSCOPIC VISUALIZATION OF CAT SCAN DATA WOULD BE A GREAT STEP FOWARD IN OBTAINING A BETTER CONCEPT OF TREATMENTVOLUMES FOR RADIATION THERAPY PLANNING. AT PRESENT, ONLY ONE OR TWO CAT SLICES ARE USED FOR TREATMENT PLANNING, AND THEY ARE USUALLY TAKEN THROUGH THE CENTRAL RAY. IN SEVERAL ANATOMICAL SITUATIONS, IT IS IMPORTANT TO OBTAIN OFF-AXIS DATA, WITH RESPECT TO THE RELATIVE POSITION OF S ...

THE FEASIBILITY OF, AND DESIGN REQUIREMENTS FOR, THE DEVELOPMENT OF A DIGITAL IMAGING OPTICAL EXTENSOMETER. THE TECHNICAL APPROACH IS TO PERFORM A DESIGN ANALYSIS UTILIZING COMPUTER MODELING TECHNIQUES, AN THEN TO SUBJECT CANDIDATE DESIGNS TO PROOF-OF-CONCEPT TESTS USING APPLICATION TEST DATA IN A LABORATORY SCANNING EXPERIMENT.

A NEW TYPE NOISE REDUCTION TECHNIQUE (1) HAS OPENED THE OPPORTUNITY TO DETECT BOTH A SIGNAL WITH NEGATIVE SIGNAL TO NOISE RATIO AND RANDOM SIGNAL ON A LINE. THE IMPORTANT ADVANTAGE OF THIS TECHNIQUE OVER EXTERNAL ENVIRONMENT NOISE AS WELL AS AN INTERNAL BACKROUND NOISE. IT PROVIDES A REAL TIME DETECTION AT A WIDE FREQUENCY RANGE, THIS VERY EFFICENT AND INEXPENSIVE APPROACH TO IMPROVE THE SNR BY TH ...

THIS PROJECT IS DESIGNED TO DEVELOP A SOLID-STATE, FULLY AUTOMATED DATA COLLECTION AND RECORDING DEVICE, CAPABLE OF MONITORING THE OPERATING PROFILE OF AN AIRCRAFT IN ORDER TO PROVIDE ACCURATE DIAGNOSTIC REAL-TIME INFORMATION NECESSARY TO DETECT POTENTIAL HAZARDOUS CONDITIONS FOR ACCIDENT PREVENTION. THE EFFORT APPLIES A CONCEPT PATENTED FOR USE IN MOTOR VEHICLES TO THE AIRCRAFT ARENA.

REDUCING THE ASH AND SULFUR CONTENT OF COAL TO LEVELS COMPARABLE WITH OIL WILL GREATLY INCREASE COAL'S ACCEPTANCE AS A COMBUSTION FUEL. TO ACHIEVE THIS GOAL WITH PHYSICAL BENEFICIATION TECHNIQUES, IT WILL BE NECESSARY TO FIRST REDUCE THE ROM COAL INTO ULTRAFINE PARTICLES. THIS GENERATION OF FINES RELEASES MOST IMPURITIES AS DISCRETE PARTICLES WITH SPECIFIC GRAVITIES (2.2-4.2) SIGNIFICANTLY HIGHER ...
