  1. 1. Novel voltage source converter based HVDC transmission system for offshore wind farms

    Författare :Stephan Meier; Hans-Peter Nee; Jan R. Svensson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Sammanfattning : Offshore wind farms have recently emerged as promising renewable energy sources. For increasing distances between offshore generation and onshore distribution grid, HVDC transmission systems based on voltage source converters can be a feasible and competitive solution. LÄS MER

  3. 2. Öppna och slutna rum : Enskiftet och de utsattas geografi

    Författare :Henrik Svensson; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; landscape; landownership; population change; migration; enclosure;

    Sammanfattning : The aim of the thesis is to study the change in the Scanian rural society and landscape during the time of the radical enclosure reform "Enskifte" (Sw.) in the early 19th century and the decades therafter up until c 1850. LÄS MER

  4. 3. Fluorescence spectroscopy in tissue for identification and temperature control of embedded lesions

    Författare :Jenny Svensson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fluorescence spectroscopy in two different biomedical applications have been studied. One field has been to explore whether fluorescence spectroscopy can be used to determine the depth of a fluorescent object inside a tissue-like medium. LÄS MER

  5. 4. Metabolic Engineering of the Central Carbon Metabolism in Streptococcus thermophilus for Enhanced Exopolysaccharide Production

    Författare :Malin Svensson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; metabolism; Biokemi; Metabolism; mykologi; Biochemistry; virologi; Mikrobiologi; bakteriologi; virology; mycology; bacteriology; Streptococcus thermophilus; Microbiology; Metabolic engineering; Lactic acid bacteria; Exopolysaccharides; Central carbon metabolism;

    Sammanfattning : The lactic acid bacterium, Streptococcus thermophilus, is used in the dairy industry in mixed cultures with Lactobacillus delbrueckii subsp. bulgaricus for the production of yoghurt. Many strains of S. thermophilus produce exopolysaccharides (EPSs) which affect the texture and viscosity of fermented food products. LÄS MER

  7. 5. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

    Författare :Mattias Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

    Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER
