  2. 21. Strength grading of structural timber and EWP laminations of Norway spruce : Development potentials

    Author : Jan Oscarsson; Anders Olsson; Marie Johansson; Mikael Perstorper; SP Sveriges Tekniska Forskningsinstitut; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bending strength; fibre angle; grain angle; knots; laser scanning; machine strength grading; modulus of elasticity; strain measurement; structural timber; tensile strength; wood; böjhållfasthet; draghållfasthet; elasticitetsmodul; fibervinkel; konstruktionsvirke; kvistar; laserskanning; maskinell hållfasthetssortering; trä; töjningsmätning; Byggteknik; Civil engineering;

    Abstract : Strength grading of structural timber is a process by which value is added to sawn products. It is to the greater part carried out using machine grading based on statistical relationships between so called indicating properties and bending strength. READ MORE

  4. 22. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

    Author : Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. READ MORE

  5. 23. Relationships between models used for teaching chemistry and those expressed by students

    Author : Karina Adbo; Susanne Wikman; Shu-Nu Chang-Rundgren; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; chemistry didactics; particulate nature of matter; phase transition; student expressed models; Swedish school; teaching models; Science Education; Naturvetenskap med utbildningsvetenskaplig inriktning; Science Education; Naturvetenskap med utbildningsvetenskaplig inriktning;

    Abstract : This thesis is focused upon chemistry as a school subject and students' interpretations and use of formally introduced teaching models. To explore students' developing repertoire of chemical models, a longitudinal interview study was undertaken spanning the first year of upper secondary school chemistry. READ MORE

  6. 24. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber

    Author : Shaheda T. Akter; Thomas K. Bader; Erik Serrano; Jan Oscarsson; Reinhard Brandner; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shear; biaxial testing; stress combination; RT-plane; moisture influence; rolling shear creep; digital image correlation; strain field; CLT connection; rotational stiffness; rullskjuvning; biaxiell undersökning; spänningskombination; RT-plan; fuktpåverkan; krypning vid rullskjuving; digital bildkorrelation; töjningsfält; KLTanslutning; rotationsstyvhet; Byggteknik; Civil engineering;

    Abstract : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.

  7. 25. Bad Death at Sandby borg : A Bioarchaeological Analysis of Intergroup Violence and Postmortem Agency of Unburied Corpses

    Author : Clara Alfsdotter; Anders Högberg; Alison Klevnäs; Linnéuniversitetet; []
    Keywords : HUMANIORA; HUMANITIES; Sandby borg; Migration period; Iron age; Massacre; Mass violence; Conflict; Unburied corpses; Postmortem agency; Taphonomy; Archaeothanatology; Forensic taphonomy; Trauma; Öland; Treatment of corpses; Folkvandringstid; järnålder; Öland; obegravda kroppar; våld; massaker; politiseing av lik; tafonomi; arkeothanatologi; Humaniora; Humanities; Archaeology; Arkeologi;

    Abstract : The subject of corpses from mass violence is surprisingly unexplored, even though the materiality of the corpse carries strong symbolic capital in conflicts. The aim of my PhD research is to create new knowledge about the implications of unburied corpses that stem from intergroup conflicts, and subsequently to add knowledge concerning how intergroup violence is organised to achieve desired social agendas.
