  2. 1. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales

    Author : Carl S. Modén; Lars Berglund; Per Johan Gustafsson; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära; Engineering mechanics; Teknisk mekanik; Biomaterials; Biomaterial;

    Abstract : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. READ MORE

  4. 2. Transverse anisotropy in softwoods : Modelling and experiments

    Author : Carl S. Modén; Lars Berglund; Lennart Salmén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; Materials science; Teknisk materialvetenskap;

    Abstract : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. READ MORE

  5. 3. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose

    Author : Erfan Oliaei; Lars Berglund; Tom S. C. Lindström; Fredrik Berthold; ‪Maria Soledad Peresin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.

  6. 4. SAR studies of Capsazepinoid Bronchodilators The B-ring and the C-region

    Author : Magnus Berglund; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bronchodilator; Capsazepine; structure activity relationship;

    Abstract : Capsazepine and similar compounds, capsazepinoids, were shown to be general inhibitors of agonist (leukotriene D4, histamine, acetylcholine, prostaglandin D2) evoked constriction of human small airway preparations. The mechanism of action remains to be elucidated, but established bronchodilator principles, e.g. READ MORE

  7. 5. NMR studies of DNA/RNA-binding proteins

    Author : Helena Berglund; KTH; []
    Keywords : ;

    Abstract : This thesis concerns the structure and internal dynamics inDNA and RNA-binding proteins. While it has long been known thata proper three-dimensional structure is essential for aprotein's ability to interact with other biomolecules, theinfluence of the inherent protein dynamics is less wellunderstood.
