  2. 1. Ab initio atomistic simulation of metals and multicomponent alloys

    Author : Fuyang Tian; Levente Vitos; Kalevi Kokko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high entropy alloys; ab inito;

    Abstract : Ab initio theory provides a powerful tool to understand and predict the behavior of materials. This thesis contains both of these aspects. First we use ab initio alloy theory to investigate a new kind of complex alloy (high-entropy alloy). READ MORE

  4. 2. Materials Design from ab initio Calculations

    Author : Sa Li; Börje Johansson; Rajeev Ahuja; Gilles Hug; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; DFT; MAX; Optics; phase transition; phonon; EOS; Fysik; Physics; Fysik;

    Abstract : This thesis presents a theoretical study of bulk materials using ab initio methods based on the density functional theory (DFT).Crystallographic structural phase transformations and phase stability for 5f-dioxides, ABO3 perovskites, and ABO4 compounds have been extensively studied.

  5. 3. Gene conversion of the mouse MHC class II

    Author : Kari Högstrand; Ulf Gyllensten; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MHC; H2; gene conversion; evolution; polymorphism; Immunology; Immunologi; immunologi; Immunology;

    Abstract : The major histocompatibility complex (MHC) is the most polymorphic vertebrate gene loci known to exist. Gene products of the MHC are responsible for presentation of antigen derived peptides to T cells of the immune system, which thereby become activated and involved in the elimination of particles recognised as non-self.

  6. 4. Prediction, Design and Determination of Protein Structures

    Author : Sebastian Rämisch; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein design; Rosetta; Fold-and-Dock; leucine rich repeat proteins; coiled-coils; molecular replacement; ab initio phasing; temperature stability; fluorescent proteins;

    Abstract : The three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. READ MORE

  7. 5. Studies of T- and B-cells for the generation of human antigen specific antibodies

    Author : Eva Andersson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; germinal center; CD4 CD57 T cells; mucin 1; in vitro immunization; human class switched antibodies; Biotechnology; Bioteknik;

    Abstract : Human antibodies generated in vitro may be highly valuable for diagnostic and therapeutic purposes. For a long time most human antibodies produced in vitro have been of the IgM isotype with rather low affinities. In this thesis a method for production of IgG switched antigen-specific human antibodies is presented. READ MORE
