  1. 11. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Författare :Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Sammanfattning : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. LÄS MER

  5. 14. Time and general practice consultations : aspects of length, attendance and quality

    Författare :Sven-Olof Andersson; Bengt Mattsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General practice; primary health care; consultation; time; doctor-patient relation; satisfaction; primary care nurse; frequent attender;

    Sammanfattning : The consultation is the GP’s form of work. How long a consultation should be, and what short/long consultations imply with regard to the satisfaction of patient and doctor has been much debated. The aim of this thesis was to study consultations with regard to content and time consumption in a short term and long term perspective. LÄS MER

  7. 15. Immunopathogenesis of relapsing fever borreliosis

    Författare :Marie Andersson; Sven Bergström; Betty P. Guo; Janis J. Weis; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Relapsing fever; Borrelia; mouse models; biological barriers; pathology; chemokines; cytokines; pregnancy; Molecular biology; Molekylärbiologi;

    Sammanfattning : Relapsing fever (RF) is caused by different species of Borrelia transmitted by soft ticks or by the human body louse. Illness is characterized by reappearing peaks of high concentrations of spirochetes in blood, concordant with fever peaks separated by asymptomatic periods. LÄS MER
