  1. 1. Cobalt and Nickel Bioavailability for Biogas Formation

    Författare :Jenny Gustavsson; Bo Svensson; Anna Karlsson; Piet N.L. Lens; Linköpings universitet; []
    Nyckelord :Biogas production; bioavailability; cobalt; nickel; sequential extraction; S XANES; 454-pyrosequencing.; Biogasproduktion; biotillgänglighet; kobolt; nickel; sekventiell extraktion; S XANES; 454-pyrosekvensering;

    Sammanfattning : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. LÄS MER

  3. 2. On morbidity and mortality in novovirus infection

    Författare :Lars Gustavsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norovirus; mortality; lactate; viral shedding; CCL5; rectal swab;

    Sammanfattning : Norovirus causes epidemic gastroenteritis. The extent of excess mortality related to norovirus infections is not established and factors that influence the duration of viral shedding have not been determined. LÄS MER

  4. 3. Nitritation and denitritation in sludge liquor treatment

    Författare :David Gustavsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitritation; denitritation; nitrous oxide; nitric oxide; nitrogen dioxide; wastewater; sludge liquor;

    Sammanfattning : Enhanced biological nitrogen removal at municipal wastewater treatment plants is a common procedure to prevent eutrophication in water bodies. Increased load, stricter effluent regulations, and demands for reduced resource and energy consumption present new challenges for the wastewater treatment plants. LÄS MER

  5. 4. Essays on trade, growth and applied econometrics

    Författare :Patrik Gustavsson Tingvall; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This dissertation consists of five essays. Three of these study countries’ specialisation patterns combining the two classical paradigms of trade theory, namely the Ricardian (technology) and the HeckscherOhlin (factor endowments) framework. LÄS MER

  7. 5. Design of enzymatic systems for the modification of cellulose fiber surfaces

    Författare :Malin Gustavsson; KTH; []
    Nyckelord :Candida antarctica lipase B; Pichia pastoris; cellulose-binding module; proteolysis; carbohydrate ester; xyloglucan endotransglycosylase; fiber modification;

    Sammanfattning : This thesis describes the design of enzymatic systems forthe modification of cellulose fiber surfaces. A single-enzymeapproach employed a conjugate between theNeocallimastix patriciarumCel6A cellulose-bindingmodule and lipase B fromCandida antarctica(CBM-CALB) to enhance theaccessibility of the enzyme to the target hydroxyl groups.
