  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

  2. 2. Levels and trends of flame retardants in the Swedish environment

    Författare :Jakob Gustavsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES;

    Sammanfattning : Flame retardants (FRs) are compounds used in, e.g., electronics and furniture to prevent fires. Due to leakage, FRs are widely spread in the environment and several FRs have been found to be environmentally persistent, bioaccumulative and toxic. LÄS MER

  3. 3. On morbidity and mortality in novovirus infection

    Författare :Lars Gustavsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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. 4. Nitritation and denitritation in sludge liquor treatment

    Författare :David Gustavsson; Institutionen 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. 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.
