THE RAPIDLY GROWING AQUACULTURE INDUSTRY IS DEDICATED TO PRODUCING FOOD FISH IN CAPTIVITY. AMONG THE MANY PROBLEMS CURRENTLY FACING THE COMMERCIAL AQUACULTURE INDUSTRY ARE DIFFICULTIES IN RAPIDLY AND ACCURATELY IDENTIFYING THE SEX AND SEXUAL MATURITY OF PUTATIVE BREEDING STOCK. THIS IS DIFFICULT BECAUSE OF THE LACK OF SEXUAL DIMORPHISM AMONG MANY FISH OF COMMERCIAL IMPORTANCE. VITELLOGENIN, AN EGG ...

A NEW PROGRAM AT NIST AIMS TO DEVELOP A FREE ELECTRON LASER (FEL) USER FACILITY TUNABLE WELL INTO THE ULTRAVIOLET. THE SHORT WAVELENGTH LIMIT OF OPERATION IS MAINLY DEPENDENT ON THE OPTICS PERFORMANCE. THE BEST KNOWN OPTICAL MATERIALSARE DEGRADED BY THE HARMONIC RADIATION PRODUCED UNAVOIDABLY DURING FEL OPERATION. THE DEVELOPMENT OF IMPROVED MATERIALSFOR THIS APPLICATION REQUIRES THE MEASUREMENT ( ...

DOVE ELECTRONICS, INC., WILL DETERMINE WHAT MECHANISMS/PARAMETERS OF ATMOSPHERIC OPTICAL SCINTILLATIONS ARE SIGNIFICANT AND USEFUL IN MEASURING TURBULENCE AND WIND . THE PROPAGA- TION PATH WILL BE CONSIDERED TO BE LINE-OF-SIGHT. AFTER THOROUGH INVESTIGATION AND DEFINITION OF THESE PARAMETERS, HOLOGRAPHIC FILTERING TECHNIQUES FOR THEIR MEASUREMENT WILL BE STUDIED. THESE TECHNIQUES WILL INCORPORTE V ...

THIS PHASE I PROJECT WILL RESEARCH THE PROBLEMS, CURRENT OPERATIONS, FILE STRUCTURES, AND DATA COMPRESSION REQUIREMENTS TO FACILITATE THE RAPID ERROR-FREE TRANSMISSIONOF WEATHER MAPS, ALPHANUMERIC WEATHER DATASETS, AND SATELLITE IMAGES. SUPPORTING THE INTERAGENCY FIRE WEATHER PROGRAM, IT WILL ALSO RESEARCH THE COMMERCIALLY AVAILABLE HARDWARE AND SOFTWARE WHICH WILL MEET TRANSPORTABILITY, RELIABILI ...

THIS PROPOSAL DESCRIBES A UNIQUE AND HIGHLY SIMPLIFIED IMMUNOLOGICAL PROCEDURE USING A MONOCLONAL ANTIBODY TO CIGUATOXIN IN A TWO-STEP PROCEDURE. THE MONOCLONAL ANTIBODY(MAB) IS PREPARED BY THE MOUSE HYBRIDOMA TECHNIQUE, USING HIGHLY PURIFIED CIGUATOXIN CONJUGATED TO PROTEIN CARRIERS. THE MAB-CTX THUS OBTAINED IS CONJUGATED TO COLLOIDAL GOLD (< 0.45 UM DIAMETER) OR COLORED LATEX PARTICLES. THIS WI ...

SPECIAL MILITARY NARROW BEAM ACOUSTIC PROJECTORS AND TRANSMISSION TECHNIQUES CAN BE EASILY ADAPTED FOR COMMERCIAL USE TO ENABLE FISHERMEN OR RESEARCHERS TO DETECT,LOCATE, AND QUANTIFY BIOLOGICAL TARGETS WITH VERY HIGH ACCURACY IN SHALLOW WATER. THE PROPOSED EFFORT WILL PROVIDE A METHOD FOR PRODUCING VERY NARROW ACOUSTIC BEAMS WITH VIRTUALLY NO SIDELOBES FROM A SMALL APERTURE PROJECTOR ARRAY. ALSO ...

THIS PROPOSAL SETS FORTH A NUMBER OF INNOVATIVE DESIGN APPROACHES THAT TOGETHER COULD REALIZE AN INEXPENSIVE GOES TRANSMITTER (LESS THAN $1000), WHICH IS THE PRODUCT SOUGHT BY DOC/NOAA UNDER SUBTOPIC 8.2.13. THE DESIGN INLCUDES A NUMBER OF NOVEL, HIGH SPEED, DIGITAL SIGNAL SYNTHESIS TECH- NIQUES WHICH ELIMINATE EXPENSIVE TUNEABLE RF COMPONENTS. A PROTOTYPE GOES TRANSMITTER WILL BE DESIGNED, FABRIC ...

TO SUPPORT THE APPLICATION OF INCREASING AMOUNTS OF DIGITAL MAPPING AND CHARTING DATA SETS, SYSTEMS MUST BE CREATED TO REPRESENT GEOGRAPHIC AND CARTOGRAPHIC INFORMATION. THESE SYSTEMS MUST HAVE THE ABILITY TO MODEL HIGH-LEVEL INFORMATION WHILE INTEGRATING LOW-LEVEL GEOGRAPHIC FEATURE AND CARTOGRAPHIC PROCESS INFORMATION AND TO RUN IN A MICRO-COMPUTER ENVIRONMENT. OBJECT-ORIENTED DATA BASE MODELS A ...
