THE BIOCHEMICAL AND SYNTHETIC CAPACITY OF HIGHER PLANTS, AS SHOWN BY THEIR NATURAL CONTENT OF SUBSTANCES, HAS BEEN USED FOR CENTURIES IN SUPPLYING MATERIALS IMPORTANT IN PHARMACOLOGY AND IN FLAVORS AND FRAGRANCES. MANY OF THESE SECONDARY PRODUCTS ARE IN SHORT SUPPLY AND AN ENORMOUS EFFORT HAS TO BE EXTENDED TO GET THEM. ATTEMPTS TO USE CELL CULTURES OF HIGHER PLANTS AS A MEANS OF PRODUCING SECONDA ...

SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

THE GOAL OF PHASE I IS DEVELOPMENT OF AN ADVANCED OPTICALLY PUMPED HELIUM MAGNETOMETER CONCEPT. THIS INSTRUMENT WILL MEASURE MAGNETIC FIELDS IN THE 1 TO 10-8 GAUSS RANGE WITH ORDER OF MAGNITUDE IMPROVEMENTS IN SENSITIVITY AND ABSOLUTE ACCURACY OVER EXISTING MAGNETOMETERS. OPTICALLY PUMPED HELIUM ISOTOPES CAN BE OPTICALLY PUMPED AND USED AS MAGNETOMETERS IN THE FOLLOWING THREE MODES: (1) VECTOR MOD ...

THE PROPOSED INNOVATION SYNTHESIZES THREE HIGH TECHNOLOGY TOOLS IN AN EFFORT TO DEVELOP A RELIABLE NUMERICAL MESOSCALEWEATHER FORECAST SYSTEM FOR USE AT THE KENNEDY SPACE CENTER FOR SHUTTLE LAUNCH AND LANDING OPERATIONS. THESE TOOLS ARE:(1) AN ADVANCED MESOSCALE NUMERICAL WEATHER PREDICTION MODEL, I.E., THE MESOSCALE ATMOSPHERIC SIMULATION SYSTEM (MASS), (2) THE CRAY-2 SUPERCOMPUTER SYSTEM, AND (3 ...

IT IS GENERALLY ACCEPTED THAT HIGHER PLANTS WILL SERVE AS IMPORTANT COMPONENTS OF ENVIRONMENTAL CONDITIONING AND FOOD PRODUCTION SYSTEMS FOR FUTURE SPACE OR PLANETARY SURFACE HABITATS. BECAUSE OF STRUCTURAL CONSIDERATIONS IT IS LIKELY THAT ATMOSPHERIC COMPOSITION AND PRESSURE WILL BE RADICALLY DIFFERENT. IN DEFINING GROWTH SYSTEMS FOR ALTEREDATMOSPHERES WE MUST UNDERSTAND HOW PLANTS OPERATE IN GEN ...

THE HYPERSONIC VEHICLES FLYING AT HIGH ALTITUDES OPERATE IN A FLOW REGIME WHERE THE NONCONTINUUM EFFECTS NEAR THE SURFACE AND FINITE SHOCK THICKNESS DUE TO LOW DENSITY MAKE THE CONVENTIONAL CONTINUUM TECHNIQUES GROSSLY INADEQUATE. CHEMICAL NONEQUILIBRIUM IS ALSO IMPORTANT UNDER THE LOW-DENSITY FLOW CONDITIONS. UNTIL RECENTLY NOT MUCH WORK HAS BEEN DONE TO EVALUATE DEFICIENCIES OF THE EXISTING CONT ...

MODELING OF THE AMBIENT AND PROMPT IONOSPHERIC REGIONS IN A THIN LAYER APPROXIMATION ALLOWS AN EFFICIENT METHOD OF DETERMINING THE TIME EVOLUTION, PROPAGATION, AND SIGNAL STRENGTH OF THE 0-10 SECOND MHD EMP ASSOCIATED WITH HIGH ALTITUDE NUCLEAR DETONATIONS.

SUBSTANTIAL PROGRESS HAS BEEN MADE IN RECENT YEARS TO DEVELOP AND VALIDATE MODELS WHICH CAN PREDICT THE PHYSICAL EFFECTS OF NUCLEAR WEAPONS ON STRATEGIC STRUCTURES. SIGNIFICANT UNCERTAINTIES REMAIN, HOWEVER, IN THE CONFIDENCE LEVELS ATTRIBUTABLE TO THESE PREDICTIVE CAPABILITIES. THIS APPROACH WOULD IDENTIFY AND PRIORITIZE THOSE ACTIVITIES, ALONG WITH THEIR ASSOCIATED BUDGETARY AND SCHEDULING CONSI ...

THIS RESEARCH ATTEMPTS TO ADVANCE THE STATE-OF-THE-ART OF BALLOON DESIGN BY DEVELOPING A METHOD TO REALISTICALLY APPROXIMATE THE STRESS LEVELS IN AN ASCENDING BALLOON. THE APPROACH WILL BE TO COMBINE EXISTING STUDIES ON ASCENT SHAPES, MATERIAL PROPERTIES, AND HEAT TRANSFER MECHANISMS TO PRODUCE A FIRST ORDER ESTIMATE OF STRESSES IN THE WALL OF A BALLOON WITH EITHER INTERNAL OR EXTERNAL CAPS. THE F ...
