  1. 16. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines

    Författare :Josefine Preuss; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray characteristics; RME; drop-in bränslen; long chain alcohols; CI engine; HVO;

    Sammanfattning : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.

  3. 17. Free radicals in cellular pathology : Mechanisms behind lipofucin formation in cultured myocardial cells

    Författare :Rasi Marzabadi Massoud; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Lipofuscin, or age pigment, may be defined as a yellowish-brown,autofluorescent, protein and lipid containing pigment that accumulates inthe lysosomal vacuome of a variety of post-mitotic cell types in man andanimals during aging. Lipofuscin is the end product of peroxidation,fragmentation and polymerization of proteins and lipids. LÄS MER

  4. 18. X-ray structure analysis of short-chain dehydrogenases/reductases

    Författare :Jordi Benach-Andreu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :crystal structure; short-chain dehydrogenases reductases; Drosophila alcohol dehydrogenase; catalytic reaction mechanism; Comamonas testosteroni 3[beta] 17[beta]hydroxysteroid dehydrogenase;

    Sammanfattning : X-ray crystallography and site-directed mutagenesis were used to better understand the structure/function relationships in the family of short-chain dehydrogenases/reductases (SDR). This group of enzymes constitutes a protein family with at least 60 members with highly diverse functions in pro- and eukaryotes. LÄS MER

  5. 19. Age pigments and the biochemical basis of their formation

    Författare :Dazhong Yin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The autofluorescent, yellow-brown pigments that accumulate over time inbiological organisms are called age pigments. Lipofuscin, known as a hallmark of aging, refers to intracellular age pigments that accumulate mainly in the lysosomes of postrnitotic cells. LÄS MER

  7. 20. Localized and systemic AL-amyloidosis : Aspects on protein structure, fibril formation and analytical methods

    Författare :Karen Ege Olsen; Jakob B. Natvig; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : AL-amyloidosis is a protein storage disease and one of the most common types of amyloidosis. The precursor protein is a monoclonal immunoglobulin light chain which originates from plasma cell dyscrasia in systemic AL-amyloidosis and is probably produced by a local plasma cell clone in localized AL-amyloidosis.
