  2. 1. Fatigue of steel bridges : New structural details and the implementation of high strength steel

    Author : Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high strength steel; fatigue; steel bridges; steel and concrete composite bridges; new structural details; linear elastic fracture mechanics; effective notch stress method; nominal stress method; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

  4. 2. Prediction of zinc-binding sites in proteins and efficient protein structure description and comparison

    Author : Nanjiang Shu; Sven Hovmöller; Elisabeth Sauer-Eriksson; Alexander Luybartsev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc-binding; shape strings; protein structures; secondary structures; machine learning; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Bioinformatics; Bioinformatik; Structural biology; Strukturbiologi; Biochemistry; biokemi; strukturbiologi; Structural Biology; Molecular Biology; molekylärbiologi;

    Abstract : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. READ MORE

  5. 3. Structural transitions of proton-gated ion channels : Involving pH sensing, heterogeneity and lipid interactions

    Author : Urška Rovšnik; Erik Lindahl; Hugues Nury; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion channels; cryo-electron microscopy; pH gating; simulations; structure-function relationship; GLIC; DeCLIC; biokemi; Biochemistry;

    Abstract : Studying protein structure and function involves analyzing the relationship between a protein's three-dimensional assembly and its dynamic biochemical activity. The superfamily of pentameric ligand-gated ion channels (pLGICs) constitutes a classic yet illuminating experimental system for structure-function studies. READ MORE

  6. 4. Identification and characterisation of chitin and cellulose synthases in oomycetes : New tools for biochemical studies and structure determination

    Author : Stefan Klinter; Vincent Bulone; Lauren S. McKee; Mirjam Czjzek; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biochemical characterisation; cellulose synthase; chitin synthase; in vitro activity assay; microtubule-interacting and trafficking domain; nanoparticle; oomycetes; phylogenetic analysis; yeast engineering; biokemisk karakterisering; cellulosasyntas; kitinsyntas; in vitro aktivitetsanalys; mikrotubulus-interagerande och -trafikerande domän; nanopartikel; oomyceter; fylogenetisk analys; jäst proteinteknik; Bioteknologi; Biotechnology;

    Abstract : Despite resembling ‘true’ fungi in terms of morphological features, oo­mycetes form a distinct eukaryotic lineage of filamentous microorganisms that belongs to the stramenopiles, a group of protists also comprising the closely-related brown algae and diatoms. Many oomycetes are devastating pathogens of plants and animals, globally causing significant economic los­ses in the agriculture and aquaculture industries, and posing considerable environmental damage to natural ecosystems.
