  1. 1. Supercritical Hydrogenation of Vegetable Oils

    Författare :Maj-Britt Macher; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium catalyst; supercritical; hydrogenation; silver ion HPLC; rapeseed oil; fatty acid methyl ester; trans fatty acid; palm oil; deactivation; propane;

    Sammanfattning : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. LÄS MER

  3. 2. Methane and Volatile Fatty Acids Production from Toxic Substrate

    Författare :- Lukitawesa; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

    Sammanfattning : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. LÄS MER

  4. 3. Factors affecting fatty acid composition in forage and milk

    Författare :Katarina Arvidsson Segerkvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aims of the studies underlying this thesis were to evaluate variations in fatty acid (FA) contents of plants used as forage for dairy cows in northern Sweden, and their effects on the FA contents of the milk. Initially, samples of timothy (Phleum pratense L.) were subjected to different pre-treatments prior to analysis. LÄS MER

    Författare :Annika Smedman; Samar Basu; Bengt Vessby; Jan I Pedersen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nutrition; Pentadecanoic acid 15:0 ; milk products; milk fat; dietary marker; coronary heart disease; anthropometric variables; conjugated linoleic acid CLA ; lipid peroxidation; inflammation; F2 isoprostane; prostaglandin F2; human; Näringslära; Nutrition; Näringslära;

    Sammanfattning : In the present thesis dietary markers for intake of milk fat, associations between intake of milk fat and risk factors for coronary heart disease (CHD), and the effects of supplementation with conjugated linoleic acid (CLA) to healthy humans are investigated.The dietary fat quality is one of the main lifestyle factors affecting risk for CHD.

  7. 5. Protein folding variants, for better or for worse? The lesson learned from HAMLET

    Författare :Malin Svensson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical biology; prion; apo; fatty acid; apoptosis; lactalbumin; folding variant; Klinisk biologi;

    Sammanfattning : By varying its secondary or tertiary structure a single protein can attain new biological functions. The amyloid forming proteins are the best known examples where a change in conformation leads to the formation of amyloid fibrils that accumulate in tissues and cause disease. LÄS MER
