  1. 31. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

    Författare :Ingrid Bölin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

    Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER

  3. 32. The effect of microstructure and temperature on the atmospheric corrosion of Mg-Al alloys

    Författare :Mohsen Esmaily; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; microstructure; temperature; corrosion product; magnesium;

    Sammanfattning : The NaCl-induced atmospheric corrosion behavior of the Mg-Al alloy AM50 produced by rheo-casting (RC) and high pressure die casting (HPDC) techniques was studied in the laboratory. The exposures were performed at 95% RH in the absence and presence of 400 ppm CO2 at 22, 4 and -4ºC. In parallel, 99.97%Mg was investigated as reference. LÄS MER

  4. 33. Thermal Issues in Testing of Advanced Systems on Chip

    Författare :Nima Aghaee Ghaleshahi; Zebo Peng; Petru Eles; Jaan Raik; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SoC test; test scheduling; Adaptive test; Temperature awareness; Process variation; Thermal simulation; 3D stacked IC 3DSIC test; Burn-in; Temperature gradients; Temperature Cycling Test; Test Ordering;

    Sammanfattning : Many cutting-edge computer and electronic products are powered by advanced Systems-on-Chip (SoC). Advanced SoCs encompass superb performance together with large number of functions. This is achieved by efficient integration of huge number of transistors. LÄS MER

  7. 35. Temperature effects on UV-B induced DNA damage and repair in plants and a lichen

    Författare :Markus Paulsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tobacco Nicotiana tabacum ; Temperature; Subarctic; Plants; Photoreactivation; Photolyase; Lichen; DNA damage; Cyclobutane pyrimidine dimers CPD ; 6-4 Photoproducts; Cladonia arbuscula ssp. mitis; Ultraviolet radiation; UV-B; Vaccinium vitis-idaea; Plant genetics; Växtgenetik;

    Sammanfattning : All living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. LÄS MER
