  1. 1. Enzymatic synthesis of lipids containing omega-3 fatty acids

    Författare :Ann-Marie Lyberg; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymologi; Proteiner; enzymology; Proteins; Enzymes; DHA; EPA; Biotechnology; Bioteknik;

    Sammanfattning : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. LÄS MER

  3. 2. Numerical Simulation of Turbulent Flows for Turbine Blade Heat Transfer Applications

    Författare :Jonas Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; k-.omega.; k-.epsilon.; explicit Runge-Kutta; finite volume; turbine; numerical method; non-linear; Navier-Stokes; supersonic; two-equation; external heat transfer; stagnation flow; two-dimensional; transition; low-Reynolds; turbulence model; impulse blade;

    Sammanfattning : Turbine blade heat transfer is an important engineering problem characterized by complex flow fields and high turbulence levels. This thesis is focused on using a full Navier-Stokes solver with two-equation eddy-viscosity models to predict external heat-transfer in single-stage, linear, two-dimensional uncooled turbine cascades.

    Sammanfattning : Gas detection is crucial in a wide range of fields and applications, such as safety and process control in the industry, atmospheric sciences, and breath diagnostics. Optical gas sensing offers some key advantages, compared to other sensing methods such as electrochemical and semiconductor sensing: high specificity, fast response, and minimal drift. LÄS MER

  5. 4. Role of Multiple Glutathione Transferases in Bioactivation of Thiopurine Prodrugs : Studies of Human Soluble Glutathione Transferases from Alpha, Kappa, Mu, Omega, Pi, Theta, and Zeta Classes

    Författare :Birgitta I. Eklund; Bengt Mannervik; Mikael Widersten; Ralf Morgenstern; Uppsala universitet; []
    Nyckelord :Biochemistry; Glutathione Transferases; Thiopurines; Prodrug; Bioactivation; Screening Method; Chemotherapy; Functional plasticity; Modulated activity; Biokemi;

    Sammanfattning : A screening method was developed for identification of catalytically active enzymes in combinatorial cDNA libraries of mutated glutathione transferase (GST) derivatives expressed in E. coli. The method is based on spraying monochlorobimane (MCB) directly over bacterial colonies growing on agar. LÄS MER
