1. 16. Determinants and Effects of Innovation : Context Matters

   Författare :Sam Tavassoli; Blekinge Tekniska Högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; Innovation determinant; Innovation effect; Firm; Region; Sweden; Industry life cycle; Cluster life cycle; Export;

   Sammanfattning : Innovation and technological change is the major factor of production, renewal, and competitiveness of firms and nations in the contemporary “knowledge economy”. The overall purpose of this dissertation is to investigate the innovative behavior of firms in various sectors and regions. LÄS MER

3. 17. On the Frequency and Q Factor Response of the Quartz Crystal Microbalance to Liquid Overlayers

   Författare :Michael Rodahl; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; piezoelectric effect; solid-liquid interface; sensors; protein adsorption; QCM; tribology; quartz crystal microbalance;

   Sammanfattning : The quartz crystal microbalance (QCM) is an ultra-sensitive weighing device. It consists of a piezoelectric quartz crystal, often in the form of a disk, which is sandwiched between a pair of evaporated electrodes. LÄS MER

4. 18. Effect of Ischaemia-Reperfusion on Rabbit Kidney and Human Brain

   Författare :Jagdish Shivlal Gondalia; Göteborgs universitet; []
   Nyckelord :Free radicals; ischaemia-reperfusion; cell bioenergetics; NMR; ESR; carotid artery stenosis; endarterectomy; allopurinol; acetylcysteine; MMP-1; ICAM-1; MCP-9; oxLDL;

   Sammanfattning : Free radicals are produced in various organs at ischaemia-reperfusion. The final stage in radical damage is lipid peroxidation. We have demonstrated previously that a lipid-soluble antioxidant improves restoration of bioenergetics in rabbit kidneys after ischaemia, as reflected in 31P spectrometry. LÄS MER

5. 19. Slopes in soft clay - management of strength mobilisation

   Författare :Victoria Svahn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remedial measure; dry crust; climate change; Slope stability; pore water pressure; in situ stress; soft clay; shear strength mobilisation;

   Sammanfattning : Many natural and man-made slopes close to buildings or infrastructure do not demonstrate sufficient levels of safety with respect to their stability. Nonetheless, it is a requirement from society that the environment we live in is safe. LÄS MER

7. 20. DIFFUSION OF IONS IN WOOD

   Författare :Reddysuresh Kolavali; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium chloride; impregnation; diffusion; Norway spruce; local concentration profiles; experimental methodology; micro-cracks; wood; Donnan effect;

   Sammanfattning : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. LÄS MER
