THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A MINIATURE ELECTRICAL CONNECTOR SUITABLE FOR PERMANENT IMPLANTATION IN THE BODY. SUCH A DEVICE IS INTENDED TO SERVE AS A CONNECT/DISCONNECT POINT FOR NEURAL PROSTHESES, ENABLING REPLACEMENT OF FAULTY COMPONENTS WITHOUT NECESSITATING REMOVAL OF AN ENTIRE IMPLANTED SYSTEM. SEVERAL DIFFERENT ELECTRICAL CONNECTORS HAVE BEEN DEVELOPED IN CONJUNCTION ...

THERMOPLASTIC COMPOSITES SUCH AS FIBERGLASS/PPS ARE STRONG, LIGHTWEIGHT, TOUGH MATERIALS SUITABLE FOR HARSH ENVIRONMENTS WHERE WEIGHT SAVINGS AND DURABILITY ARE REQUIRED. THIS PROGRAM IS DESIGNED TO APPLY THOSE BENEFITS TO TEMPORARY ROADWAY SURFACES FOR MILITARY BRIDGE SITE ACESS/EGRESS. AFTER A REVIEW OF PRIOR WORK, ESPECIALLY TESTING OF SANDWICH PANELS, IMPROVED PANEL UTILIZING FIBERGLASS/PPD SK ...

AN IMPORTANT ASPECT OF MANY ENERGY INTENSIVE PROCESSES IS THE ABILITY TO HAVE ON-LINE MONITORING. THIS ENSURES OPERATOR AND ENVIRONMENTAL SAFETY AS WELL AS PROPER OPERATION OF THE PLANT. CONSEQUENTLY, THERE IS A GREAT NEEDFOR DIAGNOSTIC INSTRUMENTS FOR MULTIPHASE MEDIA WHICH CAN FUNCTION IN DIFFICULT ENVIRONMENTS. THE GOAL OF THIS PHASE I AND PHASE II PROJECT IS THE DEVELOPMENT OF A RAPID, RUGGED, ...

A MACHINE TO EVALUATE THE FRICTION AND WEAR PROPERTIES OF MATERIALS AT TEMPERATURES UP TO 1000 DEG C IS PROPOSED. BOTH LUBRICATED AND UNLUBRICATED TESTING WITH LIQUIDS AND SOLIDS WILL BE POSSIBLE USING A PIN-ON-DISC GEOMETRY. COMPLETE CONTROL OVER THE TEST ATMOSPHERE AND MANUAL OR COMPUTER-CONTROL OF ALL VARIABLES WILL BE POSSIBLE DATA ACQUISITION AND STORAGE WILL BE PERFORMED BY COMPUTER. THE TRI ...

CLEAN SOURCES OF ATOMIC CHLORINE ARE REQUIRED FOR MECHANISTIC STUDIES OF SEMICONDUCTOR ETCHING PROCESSES. IN THIS PROPOSAL, AERODYNE RESEARCH, INC. DESCRIBES MODIFICATIONS TO AN EXISTING ULTRAHIGH VACUUM COMPATIBLE, EFFUSIVE BEAM, MICROWAVE DISCHARGE FLUORINE ATOM SOURCE WHICH WOULD ALLOW ITS USE AS A SOURCE OF CHLORINE ATOMS, AND THEY DEFINE MEASUREMENTS TO CHARACTERIZE AND DEMONSTRATE ITS OPERAT ...

THE PURPOSE OF THE PROPOSED STUDY IS THE DEVELOPMENT OF INSTRUMENTATION TO MEASURE FLUXES OF ATMOSPHERIC TRACE GASES TO OR FROM THE EARTH'S SURFACE. THE METHOD WE PROPOSEIS BASED ON THE WELL ESTABLISHED EDDY CORRELATION TECHNIQUE AND WOULD USE A TUNABLE DIODE LASER LIGHT SOURCE COMBINED WITH A MULTIPLE PASS ABSORPTION CELL TO DETECT TRACE SPECIES AT SUB-PART-PER-BILLION LEVELS. THE PROPOSED INSTRU ...

THE PURPOSE OF THIS STUDY IS THE DEVELOPMENT OF INSTRUMENTATION TO MEASURE DRY DEPOSITION RATES OF ATMOSPHERIC TRACE GASES. THE METHOD IS BASED ON THE CONCENTRATION GRADIENT TECHNIQUE AND WILL USE A TUNABLE DIODE LASER LIGHT SOURCE COMBINED WITH LONG LINE-OF-SIGHT ABSORPTION PATHS TO DETECT TRACE SPECIES AT PART-PER-BILLIONCONCENTRATIONS. THE INSTRUMENT WILL BE DESIGNED SPECIFICALLY FOR THE DIRECT ...

PRESENT INFRARED DECOYS FOR PROTECTION OF NAVY SHIPS ARE RELIABLE, HIGH INTENSITY COMBUSTION SOURCES. HOWEVER, THEIR EMISSION SPECTRA HAVE CHARACTERISTICS WHICH ALLOW THEM TO BE DISTINGUISHED FROM THE SHIPS THEY ARE INTENDED TO PROTECT. IT IS DESIRABLE TO DEVELOP MODIFIED FUELS WHOSE COMBUSTION WOULD PRODUCE INFRARED SIGNATURES WITH THE APPROPRIATE SPECTRAL PROPERTIES. THIS GOAL REQUIRES A DETAILE ...

THALLIUM BROMIDE (T1BR) IS A NEW CUBIC SEMICONDUCTOR. THE HIGH ATOMIC NUMBERS OF ITS CONSTITUENT ELEMENTS GIVES IT EXTRAORDINARY PHOTOELECTRIC ABSORPTION EFFICIENCY FOR GAMMA PHOTONS, WHILE ITS 2.5 EV BANDGAP PROMISES PERFORMANCE AT TEMPERATURES UP TO 250XC. IT HAS SHOWN SOME PROMISE AS AHIGH EFFICIENCY SOLID-STATE DETECTOR, BUT EARLY DEVICES WERELIMITED BY MATERIAL IMPURITIES AND IMPERFECTIONS. I ...

ONE OF THE MOST ACTIVE AND CHALLENGING FIELDS IN MOLECULAR BIOLOGY TODAY IS THE GENETIC STUDY OF EUKARYOTIC SYSTEMS. AN ESSENTIAL, BUT OFTEN RATE LIMITING STEP IN THIS AREA IS THE SCREENING OF DNA LIBRARIES FOR GENE MAPPING. THIS PROCEDURE USES RADIOLABEL HYBRIDIZATION TECHNIQUES AND AUTORADIOGRAPHY TO ACHIEVE THE REQUIRED SENSITIVITY AND SPECIFICITY. THE PARTICULAR PART OF THE PROCESS THAT THIS P ...
