BECAUSE OF THE EXPENSE AND COMPLEXITY OF MANNED FLIGHTS IT IS DESIRABLE TO PERFORM MANY OF THE NASA SPACE MISSIONS BY TELEOPERATOR CONTROL OF SPACE-BASED ROBOTIC SYSTEMS. THE REMOTE ORBITAL SERVICING SYSTEM (ROSS) IS BEING DEVELOPED TO ENABLE AN UNMANNED SPACE VEHICLE TO PERFORM MAINTENANCE AND REPAIR DUTIES. UNLIKE INDUSTRIAL ROBOTS, THE ROBOTIC SERVICER KIT PORTION OF ROSS WILL NEED TO OPERATE I ...

WORK IS PROPOSE TO ASSESS THE FEASIBILTY OF SODIUM\SULFUR-SELENIUM BATTERIES FOR ELECTRICALLY POWERED WEAPONS SYSTEMS ABOARD AIR BREATHING AIRCRAFT AND FOR ENERGY STORAGE ABOARD ORBITAL FLIGHT VEHICLES. SEVERAL POTENTIAL ADANTAGES OF THE SODIUM\ SULFUR-SELENIUM BATTERY OVER THE SODIUM-SULFUR BATTERY ARE POINTED OUT, INCLUDING HIGHER POWER AND ENERGY DENSITIES AND LONGER LIFETIMES. BASED ON SOME PR ...

THE OBJECTIVE OF THIS PROJECT IS TO ESTABLISH METHODS FOR CONJUGATING THE POTENT MARINE TOXIN, PALYTOXIN TO ANTIBODIES IN SUCH A WAY THAT SPECIFIC CYTOTOXICITY OF TARGET CELLS IS POSSIBLE. THE PRODUCT, IMMUNOPALYTOXIN (IPT), SHOULD BE EASILY PREPARED, HAVE HIGH SPECIFIC CYTOTOXIC ACTIVITY AND BE MINIMALLY TOXIC TO UNRELATED CELLSOR INTACT ANIMALS. THIS WORK WILL INVESTIGATE CHEMICAL LINKAGES BETWE ...

THE TRANSFER OF TISSUE CULTUIRED PLANTS FROM IN VITRO TO OPEN GREENHOUSE ENVIRONMENTS IS FREQUENTLY A MULTI-STAGED, LABOR INTENSIVE PROCESS THAT CAN RAISE PRODUCTION COSTS TO COMMERCIALLY PROHIBITIVE LEVELS. RESEARCH IS UNDERWAY TO TEST THE FEASIBILITY OF DEVELOPING A CONSOLIDATED, COST- EFFECTIVETRANSFER PLUG SYSTEM THAT WILL ALLOW PLANTS TO BE TRANSFERRED, ROOTED, INOCULATED WITH BENEFICIAL MYCO ...

THE GRANTEE INTENDS TO APPLY THE PRESSURE GRADIENTS GENERATED BY STANDING ULTRASONIC WAVES TO SEPARATE THE CELLULAR ELEMENTS OF BLOOD FROM PLASMA. PRELIMINARY TESTS IN OUR LAB HAVE SHOWN THAT A STANDING ULTRASONIC WAVE IN THE 1 TO 2 MHZ RANGE PRODUCES ALTERNATE BANDS OF RED BLOOD CELLS AND CLEAR PLASMA IN STATIONARY BLOOD CONTAINED BETWEENA THIN PLASTIC MEMBRANE. ENERGY LEVELS REQUIRED FOR SEPARAT ...

THE UBTL DIVISION OF TECHNOLOGY RESEARCH ASSOCIATES, INC. PROPOSES TO CONDUCT A PRELIMINARY EVALUATION OBSERVING THE EFFECTS RESULTING FROM THE APPLICATION OF A CONSTRICTION DEVICE OF NEW AND NOVEL DESIGN ON THE COLON OF ANIMALS. THEDEVICE IS INTENDED TO PROVIDE AN ALTERNATIVE TO THE KOCH POUCH AS AN INDWELLING CONTAINER AND THE ONLY AVAILABLE ALTERNATIVE TO THE SIMPLE EXTERNAL STOMA WHICH REQUIRE ...

SILICON CARBIDE (SIC), ALUMINUM OXYCARBIDE (A12OC), AND ALUMINUM NITRIDE (AIN) ALL HAVE THE SAME 2H WURZITE CRYSTAL STRUCTURE AND FORM A COMPLETE SOLID SOLUTION. RESEARCH IN THE SIC-ALN SOLID SOLUTION SYSTEM HAS SHOWN THAT THE CREEP CHARACTERISTICS OF THIS MATERIAL ARE VERY DESIRABLE FOR HIGH TEMPERATURE APPLICATIONS. IT IS BELIEVED THAT THE LOW CREEP RATE IS THE RESULT OF GRAIN BOUNDARIES DEVOID ...

A SYSTEM UTILIZING THE FREE-WING CONCEPT HAS BEEN DESIGNED FOR LIGHT AND VERY LIGHT WING-LOADING AIRCRAFT THAT ACCOMMODATES MODERATE TO HEAVY TURBULENCE WITHOUT TRANSMITTING HIGH GUST LOADINGS TO THE AIRFRAME OR THREATENING LOSS OF CONTROL. THE PROJECT WILL TEST THE SYSTEM IN A RESEARCH VEHICLE APPROXIMATING THE DESIGN CRITERIA SET FORTH IN 14 CFR, PART 103; THE RESEARCH VEHICLE IS UNMANNED.

WE PROPOSE TO DEVELOP AN IMMUNOASSAY FOR THE PESTICIDE, CARBOFURAN. PHASE I WILL CONSIST OF SYNTHESIZING SUITABLE HAPTENS, CONJUGATING THESE HAPTENS TO AN IMMUNOGENIC CARRIER, PREPARING AND SCREENING RABBIT ANTISERA, AND CONDUCTING PRELIMINARY COMPETITIVE ELISA TESTS TO DEMONSTRATE THE FEASIBILITY OF THIS APPROACH TO A RAPID, ECONOMICAL PESTICIDE DETECTION SYSTEM.

TO MEET THE DEMANDS OF INDUSTRIAL AUTOMATION AND TO REMOVE HUMAN WORKERS FROM HAZARDOUS ENVIRON- MENTS, MORE SOPHISTICATED, ECONOMICAL ROBOTS WILL BE NEEDED. SPECIFICALLY, THESE MACHINES WILL BE GENERAL- PURPOSE DEVICES (EITHER STATIONARY OR MOBILE, E.G., AUTONOMOUS VEHICLES) CAPABLE OF BEING READILY RE- PLETELY DISPERSED SILICA PARTICLES. THE CERMET WILL PRODUCE A CASTABLE AND RECASTABLE MATERIAL ...
