  1. 1. Extinction in Molecular Clouds : Case of Barnard 335

    Författare :Sven Olofsson; Göran Olofsson; Kalevi Mattila; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ISM; interstellar medium; extinction; molecular cloud; Astronomy; astronomi; Astronomy; astronomi;

    Sammanfattning : The Bok globule B335 is a small molecular cloud in the solar neighbourhood near the galactic plane. The aim for this three-paper-study is to construct and analyze the extinction for this globule. The method we apply is to use the light from field stars behind the cloud in broadband filters ranging from UV to the mid-infrared. LÄS MER

  3. 2. Biomass residues as resources : An expanded life-cycle perspective

    Författare :Johanna Olofsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass residues; biofuels; life cycle assessment; climate change; circular bioeconomy;

    Sammanfattning : Biomass residues have been identified as potentially promising resources for production of bio-based products and fuels with low climate impacts. Unlike primary biomass such as crops, using residual biomass may avoid issues such as competition over land for food and feed production. LÄS MER

  4. 3. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization

    Författare :Nils-Erik Olofsson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Olofsson;

    Sammanfattning : This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. LÄS MER

  7. 5. Högskolebildningens fem ansikten : studerandes föreställningar om kunskapspotentialer i teknik, medicin, ekonomi och psykologi: en kvalitativ utvärderingsstudie

    Författare :Anders Olofsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Notions of content; transmission of knowledge; acquisition of knowledge; evaluation of higher education; qualitative methods; Education;

    Sammanfattning : The purpose of this study is to examine the process of stabilization and/or change in university students' notions of content and transmission and acquisition of knowledge. The subjects, 25 students of engineering, economics, medicine, and psychology, were interviewed at the beginning and the end of their training period. LÄS MER
