  1. 1. Effects of Selection and Demography on DNA Polymorphism in Black Mustard (Brassica nigra)

    Författare :Per Sjödin; Martin Lascoux; Ulf Lagercrantz; Mikkel Schierup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; population genetics; Genetik; Genetics; Genetik;

    Sammanfattning : The evolution of three genes from the CONSTANS-LIKE gene family is studied in Brassica nigra. We use a combination of population genetic and phylogenetic techniques in order to assess the relative importance of selection and demography on the pattern of DNA variation. LÄS MER

  3. 2. Steel-to-timber dowel joints : Influence of moisture induced stresses

    Författare :Johan Sjödin; Hans Petersson; Carl-Johan Johansson; Per-Johan Gustavsson; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; moisture-induced deformations; timber structures; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of a loaded building depends strongly on the structural configuration and the capacity of the joints. LÄS MER

  4. 3. User-involved service innovation : Three participating perspectives on co-creation

    Författare :Carina Sjödin; Magnus Wiktorsson; Bengt Köping Olsson; Anna-Lena Carlsson; Per Kristensson; Mattias Elg; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; open innovation; user involvement; co-creation; service logic; Innovation and Design; innovation och design;

    Sammanfattning : The involvement of customers and other stakeholders in the innovation process is proposed to be a key success factor and something that makes companies more competitive. As a consequence, more and more organizations alter their innovation strategy accordingly. LÄS MER

  5. 4. Population-level consequences of spatial interactions

    Författare :Henrik Sjödin; Göran Englund; Åke Brännström; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : How is the nature of populations governed by the movement decisions made by their members? This is the core question in this thesis. To answer this question, I first assume that s movement decisions are based on conditions in their local environment. LÄS MER

  7. 5. Strength and Moisture Aspects of Steel Timber Dowel Joints in Glulam Structures : An Experimental and Numerical Study

    Författare :Johan Sjödin; Erik Serrano; Per Johan Gustafsson; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; glu-lam beams; glulam structures; linear elastic fracture mechanics; moisture-induced stresses; numerical simulations; short term capacity.; Building engineering; Byggnadsteknik;

    Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of e.g. a building depends strongly on the structural configuration and the capacity of its joints. LÄS MER
