  1. 1. Fungal Lectins. Molecular structure and function of a member of a novel lectin family

    Författare :Stefan Rosén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; possible functions; expression; localization; binding specificities; primary and secondary structure; Agaricus bisporus; Arthrobotrys oligospora; Fungi; novel lectin family; Biology; Biologi;

    Sammanfattning : Lectins defined as non-enzyme, non-immunoglobulin carbohydrate binding proteins, have been found in a wide variety of viruses, bacteria, fungi, plants and animals. Although lectins have been purified from more than 60 different species of fungi, the structure and biological functions of these proteins are not well known. LÄS MER

  3. 3. Open Source Business Model : Balancing Customers and Community

    Författare :Thomas Rosén; Staffan Brege; Anna Öhrwall-Rönnbäck; Stefan Hrastinski; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Open Source Software; Business Models; Strategic Management; Market Positioning; Resource Based View; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : Free and Open Source Software has not only increased researchers’ interest about community-driven software development, but lately, interest from commercial actors increased as well. In addition, some scientists have claimed that Open Source Software has entered a new phase: OSS 2.0. LÄS MER

  4. 4. On reliability-based design of rock tunnel support

    Författare :William Bjureland; Stefan Larsson; Fredrik Johansson; Johan Spross; Lars Rosén; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnation.; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. LÄS MER

  5. 5. Reliability-based design of rock tunnel support

    Författare :William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. LÄS MER
