MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP DATA COMPRESSIONTECHNIQUES USED TO COMPRESS DIGITAL ENVIRONMENTAL SATELLITE DATA FROM THE NATIONAL CLIMATIC DATA CENTER (NCDC) ARCHIVES SUCH THAT THE RESULTING DATA CAN BE READILY USED WITHIN THE LIMITED RESOURCES OF PC/AT SYSTEMS. THE JOINT PHOTOGRAPHIC EXPERTS GROUP (JPEG) HAS DEVELOPED ANINTERNATIONAL STANDARD FOR THE COMPRESSION OF CONTINUOUS TONE DI ...

THE DECLINE IN THE NEW ENGLAND (NE) GROUND FISH STOCK IS SEVERELY AFFECTING THE NE FISHERIES' ECONOMY. TO REVERSE THIS DESTRUCTIVE TREND, NMFS HAS THE DIFFICULT AND UNPOPULARTASK OF IMPLEMENTING STOCK RECOVERY PROGRAMS WHICH REQUIRE CATCH REDUCTIONS. NMFS REPORTS 70% OF PRESENT FISH STOCKS ARE DOGFISH AND SKATES WHICH ARE UNDER-UTILIZED AND ARE GROUND FISH PREDATORS. ALTHOUGH THESE ABUNDANT FISH H ...

FIBER REINFORCED POLYMERIC COMPOSITES CAN REDUCE WEIGHT, INCREASE CRASHWORTHINESS, AND REDUCE CORROSION RELATIVE TO METALS. HOWEVER, LOW COST MANUFACTURING APPROACHES ARE NEEDED IN ORDER FOR THESE MATERIALS TO BE COMPETITIVE IN HIGH VOLUME AUTOMOTIVE APPLICATIONS. LIQUID COMPOSITE MOLDING (LCM) IS RECOGNIZED AS A PROMISING METHOD FOR RAPID, LOW COST FABRICATION. LOW COST, COMPLEX PREFORMS ARE NEED ...

THREE TO FOUR MILLION YOUNG CHILDREN FROM ALL LEVELS OF SOCIETY ARE EXPOSED TO ENVIRONMENTAL SOURCES OF LEAD AT CONCENTRATIONS THAT PLACE THEM AT RISK FOR ADVERSE HEALTH EFFECTS. YET, THERE IS NO TOOL AVAILABLE FOR MEASURING TOTAL PEDIATRIC BODY BURDEN OF LEAD. THIS PROJECT WILL DEVELOP AN X-RAY FLUORESCENCE (XRF) INSTRUMENT THAT WILL ALLOW MEASUREMENT OF BODY LEAD BURDEN IN CHILDREN IN VIVO AND N ...

CENTRIFUGAL BLOOD PUMPS HAVE BEEN USED EXTENSIVELY FOR SHORT-TERM CIRCULATORY ASSISTANCE AND PERFUSION PUMPS. THEIR UTILITY FOR LONG-TERM VENTRICULAR ASSISTANCE IS LIMITED BY THROMBUS FORMATION AT THE SHAFT SEAL. ABIOMED, INC., WILL DEVELOP A MAGNETICALLY SUSPENDED CENTRIFUGAL BLOOD PUMP THAT WILL HAVE NO SHAFT SEAL AND BE SUITABLE FOR LONG-TERM CIRCULATORY SUPPORT IN EITHER AN IMPLANTED OR EXTRAC ...

THIS RESEARCH WILL DEMONSTRATE THAT A NEW 1.9-MU M LASER CAN PERFORM LASER-ASSISTED VASCULAR ANASTOMOSES OF SMALL-DIAMETER VESSELS (1 TO 5 MM). THE 1.9-MU M LIGHT HAS OPTIMAL ABSORPTION CHARACTERISTICS TO ENSURE AN EVEN DEPOSITION OF ENERGY IN THE VESSEL WALL. THIS SHOULD RESULTIN A MORE DESIRED TEMPERATURE PROFILE IN THE REGION OF THE ANASTOMOSIS WHEN COMPARED WITH ALTERNATIVE SOURCES. THE PROPOS ...

THE OBJECTIVE IS TO DEVELOP A PERIODONTAL PROBE CAPABLE OF MEASURING SITE TEMPERATURE AND POCKET DEPTH SIMULTANEOUSLY AND AUTOMATICALLY. THE PROBE IS INTENDED TO BE A RAPID SCREENING DEVICE FOR THE STATE OF PERIODONTAL HEALTH DURING ROUTINE DENTAL EXAMINATIONS. STUDIES HAVE SHOWN THAT THE INFLAMED SULCUS IS ACCOMPANIED BY ELEVATED SITE TEMPERATURES. POCKET DEPTHS ARE ROUTINELY MEASURED DURING DENT ...

THE OBJECT OF THIS RESEARCH IS TO DEVELOP AN ANTI-HEPATITIS B VIRUS PRO-DRUG WHICH WILL CONCENTRATE IN THE INFECTED LIVER TISSUE BY BINDING THE HEPATIC ASIALOGLYCOPROTEIN RECEPTOR AND RELEASING THE ACTIVE FORM OF THE DRUG IN THE HEPATOCYTE. TOWARD THIS END, A NUMBER OF ADENOSINE ARABINOFURANOSIDE/ARABINOGALACTAN CONJUGATES WILL BE SYNTHESIZED. THE CONJUGATES WILL BE EVALUATED AS SUITABLE PRODRUGS ...
