NEW MATERIALS ARE BEING DEVELOPED EVERYDAY AND ARE REVOLUTIONIZING PRODUCTS AND PROCESSES AT AN ASTOUNDING RATE. IN RECENT YEARS, THE ROADSIDE SAFETY APPURTENANCE FIELD HAS BEEN AFFECTED AS WELL, AS NEW MATERIALS HAVE BEEN APPLIED TO PRODUCE IMPROVED DESIGNS IN A VARIETY OF SITUATIONS. IN RECENT YEARS PLASTICS, CERAMICS, HIGH STRENGTH FIBERS AND COMPOSITES HAVE BECOME MORE WIDELY USED IN INDUSTRY ...

THE MAIN OBJECTIVE OF THIS PHASE I PROJECT WAS TO ESTABLISH A SOURCE OF SERUM-FREE MEDIUM SUITABLE FOR SUSTAINED GROWTH OF EARLY PASSAGE SYRIAN HAMSTER EMBRYO (SHE) CELLS. SPECIFIC AIMS INCLUDED SELECTION OF A BASAL MEDIUM SUPPORTIVE OF CLONAL GROWTH IN LIMITING SERUM CONCENTRATIONS, REPLACEMENT OF SERUM BY SELECTED GROWTH FACTORS AND HORMONES, OPTIMIZATION OF SUPPLEMENTS BY CLONAL TITRATIONS, AND ...

THE LONG-TERM OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A RAPID, SPECIFIC, COST-EFFECTIVE TEST FOR HUMAN ANTIBODIES TO HUMAN IMMUNODEFICIENCY VIRUS (HIV) ANTIGENS UTILIZING A NOVEL CAPACITIVE AFFINITY SENSOR TECHNOLOGY. THE SPECIFIC AIMS OF THIS RESEARCH ARE: 1) TO EVALUATE METHODS BY WHICH HIV ANTIGENS FROM VIRAL PROTEINS GP41 AND P24 CAN BE IMMOBILIZED ON THE SURFACE OF THE BIOSENSOR AND 2) TO DE ...

PROPOSES A FRAMED STRUCTURE (TO SUPPORT THREE-DIMENSIONAL DECOY COVERS) THAT IS COLLAPSIBLE, LIGHTWEIGHT, AND RAPIDLY DEPLOYABLE. STOWED DIMENSIONS ARE APPROXIMATELY 45" X 26" X 18". THE DECOY STRUCTURE HAS THE FOLLOWING FEATURES: (1) COLLAPSES TO 2% OF DEPLOYED VOLUME; (2) DEPLOYS ON UNEVEN TERRAIN WITH NO EXPOSED FRAME; (3) INCORPORATES CANVAS INTEGRATED STRUCTURAL CABLES; (4) EFFECTS DEPLOYMENT ...

THE RESEARCH PROPOSED IS TO INVESTIGATE THE FEASIBILITY OF WRITING A SOFTWARE PACKAGE FOR PERSONAL WORKSTATIONS THAT WILL HELP CLINICAL RESEARCHERS AND THEIR ASSISTANTS CARRY OUT THE DESIGN, DATA COLLECTION, DATA STORAGE, AND FORMAL AND EXPLORATORY ANALYSES OF CLINICAL TRIALS. THE PURPOSE OF SUCH SOFTWARE WILL BE TO ASSIST THE SINGLE RESEARCHER OR THE SMALL GROUP DOING SMALL- TO MODERATE-SIZED TRI ...

DROWNING IS A LEADING CAUSE OF ACCIDENTAL DEATH TO CHILDREN UNDER FIVE; TWO-THIRDS OF THESE DEATHS OCCUR IN HOME SWIMMING POOLS. TWO RECENT MAJOR REPORTS (SEDNEY ET AL., 1987; PRESENT, 1987) HAVE FURTHERED UNDERSTANDING OF THE SAFETY PROBLEM. TYPICAL ACCIDENT SCENARIOS ARE POTENTIALLY SUSCEPTIBLE TO A VARIETY OF SAFETY INTERVENTION STRATEGIES, BOTH IN HARDWARE AND BEHAVIORALLY. NO CURRENTLY AVAILA ...

THE PURPOSE OF THE PROPOSED RESEARCH AND DEVELOPMENT EFFORT IS TO DEVELOP A LOW COST/GENERAL PURPOSE ACR-NEMA PACS INTERFACE. THE LONG TERM GOAL OF THIS EFFORT IS THE DEVELOPMENT OF AN APPLICATION SPECIFIC INTEGRATED CIRCUIT (ASIC) IMPLEMENTATION OF THE ACR-NEMA INTERFACE STANDARD. THIS ASIC WOULD CONTAIN THE INTERFACE TRANSCEIVERS AND THE LOGIC TO IMPLEMENT THE PHYSICAL AND DATALINK LAYERS OF THE ...

THE PROPOSED PROGRAM INVESTIGATES THE USE OF MULTI-EXPERT SYSTEM CONCEPTS FOR TERRAIN AND TACTICAL KNOWLEDGE, AND APPLIED THOSE CONCEPTS TO TRACK HISTORY FILES PRODUCED BY A GROUND SURVEILLANCE RADAR TRACK PROCESSOR. PRESENTLY, A TRAINED OPERATOR MUST EXAMIND THE TARGET REPORTS, WHICH ARE DISPLAYED AGAINST A TERRAIN OVERLAY, AND ATTEMPT TO DETERMINE THE NATURE OF THE TARGET AND ITS HOSTILE INTENT. ...

THE MULTIPLE SUBMUNITION FUNCTION COUNTING STUDY CAN BE UTILIZED TO EVALUATE THE EFFECTIVENESS OF AN EXPLOSION MONITORING SYSTEM. SENSORS DISTRIBUTED ALONG THE EDGES OF THE IDENTIFIED ZONE WILL FEED THE SIGNAL VIA TELEPHONE CABLE INTO A CENTRAL COMPUTER. THE SIGNALS WILL BE PROCESSED BY SYNTHETIC APERTURE TECHNIQUES TO YIELD THE NUMBER AND LOCATION OF THE MUNITION STRIKES. THE MOST PROMISING SYNTH ...

FOR MANY YEARS, THE NATIONAL CANCER INSTITUTE (NCI) HAS SURVEYED THE CHEMICAL LITERATURE TO IDENTIFY NEW CHEMICAL COMPOUNDS OF INTEREST FOR TESTING AGAINST CANCER. THE CHEMICAL STRUCTURE OF ALL SUCH COMPOUNDS MUST BE ENTERED INTO A COMPUTER SYSTEM SO THAT THE COMPOUNDS CAN BE REGISTERED AGAINST PREVIOUSLY TESTED COMPOUNDS, AND SO THAT RECORDS OF THE CHEMICAL STRUCTURE CAN BE SEARCHED AND DISPLAYED ...
