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 PHYSIOLOGICAL-THERMODYNAMIC BASIS FOR HYBRID VIGOR (YIELD HETEROSIS) IN CORN AND OTHER CROPS IS NOT PRESENTLY KNOWN. THUS, DEVELOPMENT AND SELECTION OF INBRED LINES FOR HYBRID VIGOR RELIES ON GENERAL KNOWLEDGE ABOUT HETEROTIC GROUPS, NUMEROUS CROSSES, AND EXTENSIVE FIELD TESTS TO ACHIEVE THE INDUSTRY AVERAGE OF 1 TO 2 BU/ACRE/YR INCREASE IN YIELD. EACH COMMERCIAL HYBRID MAY COST FROM $1.2 TO $ ...

THIS PROJECT WILL SEEK TO IDENTIFY ENTOMOPATHOGENIC ORGANISMS THAT ARE EFFECTIVE IN CONTROLLING INFESTATIONS OF SOIL-BORNE INSECT PESTS AND TO PROVIDE DELIVERY SYSTEMS WHICH ENSURE THEIR FIELD EFFICACY. ECOSCIENCE WILL BUILD ONPREVIOUS EXPERIENCE WITH CORN ROOTWORM (CRW) AS A MODEL SOILPEST FOR THESE STUDIES, AMPLIFYING OUR COLLECTION OF ORGANISMS PATHOGENIC TO CRW, WITH ISOLATES CAPABLE OF SUSTAI ...

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 ...

TOXIC HEAVY METALS, SUCH AS LEAD AND CADMIUM, ARE PREVALENT IN THE ENVIRONMENT DUE TO THEIR HIGH INDUSTRIAL USE. THESE TOXIC METALS ARE CUMULATIVE POISONS AND ARE TOXIC EVEN AT LOW DOSES, CAUSING EITHER CHRONIC OR ACUTE TOXICITY WITH PRIMARILY HEPATOTOXIC, NEPHROTOXIC OR NEUROTOXIC EFFECTS. THERE ARE NO USEFUL RAPID SCREENING TESTS TO DETECT CADMIUM IN WATER OR ON SURFACES. THE TESTS AVAILABLE FOR ...
