    Sammanfattning : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. LÄS MER

  4. 3. Characterization of oxy-fuel flames - their composition, temperature and radiation

    Författare :Klas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; O2 CO2; NO formation; Radiation; Oxy-fuel; Flame properties;

    Sammanfattning : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. LÄS MER

  5. 4. Crystallographic Aspects of Protein Phasing at Very Low Resolution

    Författare :Klas Andersson; Jens Nyborg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : A protein crystallographic method for obtaining structure factor phases of low-order reflections is presented. It is based on four observations: 1) The electron density inside proteins is relatively smooth and uniform at low resolution. LÄS MER

  7. 5. Deliberativ undervisning – en empirisk studie

    Författare :Klas Andersson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; deliberative teaching; knowledge; democratic citizenship; field experiment; upper secondary school; vocational program.;

    Sammanfattning : Since the early 2000s, the deliberative turn in democratic theory has influenced the debate on teaching. The proponents of deliberation in education have argued that deliberative teaching both enhances subject knowledge and democratic citizenship among students. LÄS MER
