  1. 11. A high order method for simulation of fluid flow in complex geometries

    Författare :Erik Stålberg; KTH; []
    Nyckelord :Technology; Navier-Stokes equations; compact high order difference methods; approximate factorization; curivilinear staggered grids; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A numerical high order difference method is developed for solution of the incompressible Navier-Stokes equations. The solution is determined on a staggered curvilinear grid in two dimensions and by a Fourier expansion in the third dimension. LÄS MER

  3. 12. Essays on Financial Risks and Derivatives with Applications to Electricity Markets and Credit Markets

    Författare :Rikard Green; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Markov Chain Monte Carlo; Jump Diffusion Process; Stochastic Volatility; VaR; Electricity Markets; Market Risk; Forward Curve; Credit Risk; Currency Effects;

    Sammanfattning : Contracts traded on international financial and commodity markets are associated with complex risk structures. In this dissertation we are concerned with two specific types of risks; market risks and credit risks. The first chapter investigates market risks in the context of the Nordic electricity market.

  5. 14. Mammalian thioredoxin reductase as a drug target in anticancer therapy through direct apoptosis induction by selenium compromised forms of the protein

    Författare :Karin Anestål; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Thioredoxin reductase; TrxR1; SecTRAPs; selenoproteins; apoptosis; caspase-2; glutathione reductase; cisplatin;

    Sammanfattning : The mammalian thioredoxin system, consisting of thioredoxin(s), thioredoxin reductase(s) and NADPH, participates in the regulation of many important systems in a mammalian cell. The mammalian thioredoxin reductases (TrxR) are selenoproteins containing a selenocysteine (Sec) residue within a carboxyl terminal -Gly -Cys -Sec -Gly -COOH motif. LÄS MER
