  1. 1. Solid-phase glycoconjugate synthesis : on-resin analysis with gel-phase ¹9F NMR spectroscopy

    Författare :Mickael Mogemark; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Solid-phase synthesis; protective groups; linkers; monitoring; gel-phase; 19F NMR spectroscopy; carbohydrates; oligosaccharides; glycopeptides; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : An efficient and versatile non-destructive method to analyze the progress of solid-phase glycoconjugate synthesis with gel-phase 19F NMR spectroscopy is described. The method relies on use of fluorinated linkers and building blocks carrying fluorinated protective groups. LÄS MER

  5. 4. Affinity Two-Phase Partitioning of Liposomes and Membranes

    Författare :Irene Barinaga-Rementeria Ramírez; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturised two-phase system; levitated drop; biotin; avidin; antibody; immunoaffinity; purification; rat lung; rat liver; caveolae; membrane; Affinity two-phase partitioning; liposome; Metabolism; Biochemistry; Biokemi; metabolism;

    Sammanfattning : Affinity two-phase partitioning based on an immunoaffinity sandwich approach for the rapid and selective purification of membranes is presented in this thesis. The method was developed by studying different parameters governing the affinity partitioning of model membranes. To this end, biotinylated liposomes were used. LÄS MER

  7. 5. A numerical study of two-fluid models for dispersed two-phase flow

    Författare :Reynir Levi Gudmundsson; Björn Sjögreen; Anders Petersson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; two-phase flow; two-fluid mode; well-posedness; numerical experiments; Numerisk analys; Numerical analysis; Numerisk analys;

    Sammanfattning : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. LÄS MER
