THE OBJECTIVES OF PHASE I ARE TO DETERMINE HOW WELL THE SMALL SCALE TESTS CURRENTLY USED FOR SCREENING EXPLOSIVES, AND THE MODELS THAT DESCRIBE EXPLOSIVE BEHAVIOR IN THE SMALL SCALE TEST AND IN THE FULL SCALE MUNITION, CAN PREDICT THRESHOLDS OF EXPLOSIVE REACTION IN THE OPERATIONAL FULL SCALE MUNITION. FULL SCALE MUNITIONS WILL BE STUDIED TO DETERMINE THE CRITICAL MODE(S) OF EXPLOSIVE REACTION THA ...

THE TREND CONTINUES TOWARDS APPLYING ADVANCED COMPOSITE MATERIALS TO THE HIGH PERFORMANCE STRUCTURES ASSOCIATED WITH AEROSPACE. STRUCTURES FABRICATED FROM CARBON-CARBON AND FILAMENT WOUND COMPOSITES ARE PARTICULAR EXAMPLES. TO FULLY EXPLOIT THE PROMISE OF THESE ADVANCED STRUCTURES, NOVEL NDE TECHNIQUES ARE NEEDED FOR CHARACTERIZATION. DUAL-ENERGY LAMINOGRAPHY SPECIFICALLY ADDRESSES THE CHEMICAL, D ...

THE NEED TO APPLY EXPERT KNOWLEDGE IN THE INTERPRETATION OF MEDICAL IMAGERY AND SENSOR DATA IS WELL DOCUMENTED. RULE-BASED EXPERT SYSTEMS HAVE PROVEN THEIR VALUE IN SUCH APPLICATIONS AS MEDICAL EXPERTISE. MOST DIAGNOSTIC SYSTEMS MIMIC THE CONSULTING-ROOM ENVIRONMENT, ACQUIRING SYMPTOM DESCRIPTIONS AND LAB FINDINGS THROUGH DIALOG WITH THE USER. AUTOMATED DIAGNOSIS FROM IMAGERY AND ANALOG IS A MORE ...

THE FEASIBILITY IN DEVELOPING A NEW PALATABLE, TOXIC AND EMETIC RED SQUILL RODENTICIDE WILL BE STUDIED. BITTER RED SQUILL MASHES AND EXTRACTS WILL BE FORTIFIED WITH A NUTRIENT AND TREATED WITH A MICROORGANISM. THIS WILL IMPROVE PALATABILITY FOR RODENTS BY DEBITTERING THE RED SQUILL, WHILE MAINTAINING HIGH TOXICITY AND EMETIC ACTIVITY. THE PREPARATIONS WILL BE ANALYZED BY HPLC FOR SCILLIROSIDE, SCI ...

BUTANOL, A DIESEL-FUEL EXTENDER, CAN BE PRODUCED BY FERMENTATION OF A VARIETY OF SUGAR SOURCES BY CLOSTRIDIUM ACETOBUTYLICUM. ALTHOUGH INDUSTRIAL PRODUCTION OF BUTANOL HAS NOT BEEN SIGNIFICANT IN THE U.S. IN THE PAST 30 YEARS, TWO RECENT MAJOR DEVELOPMENTS PRESENT SUFFICIENT ENCOURAGINGRESULTS TO SUGGEST THAT BUTANOL YIELDS CAN BE IMPROVED. THESE ARE THE CAPABILITY TO MONITOR INTRACELLULAR NAD (P) ...

THE RESEARCH ADDRESSED IN THIS PROPOSAL INVOLVES AN INVESTIGATION INTO THE USE OF DIAMOND THIN FILMS AS SOLID STATE OPTICAL SWITCHES WHERE THE FILMS ARE PRODUCED BY AN INHERENTLY LOW-COST TECHNIQUE EMPLOYING PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION (PE-CVD) OF CARBON-CONTAINING GASES (E.G., METHANE). THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EVALUATE EXPERIMENTALLY THE OPTOELECTRIC PRO ...

THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EXPERIMENTALLY EVALUATE THE OPTOELECTRONIC PROPERTIES OF CHEMICAL VAPOR DEPOSITION DIAMOND THIN FILMS WITH RESPECT TO ELECTROLUMINESCENCE AND PHOTOCONDUCTION IN THE UV AND BLUE-GREEN SPECTRAL REGIONS. AS A RESULT OF SUCH EFFORTS WE WILL DETERMINE THE EXTENT TO WHICH DIAMOND THIN FILMS MAY BE USED AS LASING MEDIA OR PHOTOCONDUCTORS AND ASCERTAIN ...

ADVANCED GENETIC SCIENCES, INC. IS DEVELOPING A GENERAL METHOD FOR PRODUCING HYBRID SEED WHICH REMOVES THE PRIMARY BARRIER TO THE USE OF NUCLEAR MALE STERILE GENES. THESE GENES GIVE RISE TO MALE STERILITY ONLY WHEN THE PLANT IS HOMOZYGOUS FOR THE RECESSIVE MALE STERILITY ALLELE. AS A RESULT, MALE STERILE PLANTS MUST BE PROPAGATED BY BACKCROSSING TO MALE FERTILES, YIELDING A MIXED POPULATION OF FER ...

THE BIOCHEMICAL AND PHYSICAL ORGANIZATION OF BACTERIAL ICE NUCLEI ARE EXAMINED. AN UNDERSTANDING OF THE STRUCTURE OF THESE NUCLEI IS KEY TO THEIR PRESERVATION AND BIOTECHNOLOGICAL EXPLOITATION. FORMATION OF MEMBRANE-BOUND AGGREGATES OF ICE NUCLEATION PROTEINS HAS BEEN POSTULATED TO BE THE BASIS OF THE ACTIVITY OF THESE NUCLEI AT TEMPERATURES NEAR THE FREEZING POINT OF WATER. THE PROGRAM GOALS ARE: ...

MANY EXPLOSIVE WARHEADS ARE SENSITIVE TO INITIATION BY FRAGMENT OR BULLET IMPACT AND SYMPATHETIC DETONATION. DIRECTED-ENERGY WARHEADS IN PARTICULAR ARE OFTEN LOADED WITH VERY ENERGETIC EXPLOSIVE TO OBTAIMANCE AT THE EXPENSE OF INCREASE SENSITIVITY. THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO DETERMINE THE MOST EFFECTIVE APPROACH TO REDUCING THE SENSITIVITY OF AN EXISTING WARHEAD, SUCH AS THE SFW O ...
