  1. 16. Impact of dependencies in risk assessments of power distribution systems

    Författare :Karin Alvehag; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning :  Society has become increasingly dependent on electricity, so power system reliability is of crucial importance. However, while underinvestment leads to an unacceptable number of power outages, overinvestment will result in costs that are too high for society. The challenge is to find a socioeconomically adequate level of risk. LÄS MER

    Sammanfattning : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. LÄS MER

  4. 18. Potentials and wood fuel quality of logging residues from indigenous and planted forests in Mozambique

    Författare :Rosta Mate; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Search for complementary and alternative renewable energy sources is imperative to meet the current growing demand for wood fuel and for diversification of electricity supply sources in Mozambique. Logging residues from timber harvesting operations and whole tree biomass from short rotation coppice (SRC) are available options. LÄS MER

  5. 19. Catalytic combustion of gasified biomass for gas turbine applications

    Författare :Magnus Johansson; KTH; []
    Nyckelord :;

    Sammanfattning : Catalytic combustion is an ultra-low emission technology forgas turbines. In parallel to the ongoing development andcommercialization of catalytic combustors fired by naturalgas,an increasing interest is aimed towards renewables, such asgasified biomass. LÄS MER

  7. 20. Glutathione peroxidase and selenium in meat - Tissue and species variation, thermal stability and selenium speciation

    Författare :Charlotte Daun; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrition; Näringslära; speciation of selenium; lipid oxidation; thermal stability; RN phenotype; ageing; meat; Glutathione peroxidase; selenium;

    Sammanfattning : Lipid oxidation is a major problem in muscle foods, leading to a loss in quality and nutritional value. It occurs in raw meat but is usually more pronounced in cooked meat. Since the demands of consumers for ready-to-eat foods have increased, the control of off-flavour in cooked meat is an important industrial problem. LÄS MER
