  1. 1. Myofibrillens finstruktur i tvärstrimmig skelettmuskulatur

    Författare :Anne-Christine Edman; Michael Sjöström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle; muscle fibre; fibre type; myofilament; A-band; M-band; cryo-ultramicrotomy; electron microscopy; image analysis;

    Sammanfattning : The detailed structure of the myofibrillar material in fibres from different muscles has been studied. Specimens have been obtained from human muscles and from different muscles frequently examined in experimental studies. Both light- and electron microscopical techniques have been used. LÄS MER

  3. 2. Plastic Shrinkage Cracking In Concrete : Mitigation and Modelling

    Författare :Faez Sayahi; Mats Emborg; Andrzej Cwirzen; Hans Hedlund; Pietro Lura; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

  4. 3. Carbon Fibres from Kraft Lignin

    Författare :Ida Norberg; Monica Ek; Elisabeth Sjöholm; Göran Gellerstedt; Falk Liebner; KTH; []
    Nyckelord :;

    Sammanfattning : Kraft lignin has a high potential for use in more valuable applications than its current use as fuel in pulp mills and integrated pulp and paper mills. The possibility of using kraft lignin, a green material with a carbon content of more than 60 %, for the manufacturing of carbon fibres was investigated in this thesis. LÄS MER

  5. 4. Properties and performance of regenerated cellulose thermoset biocomposites

    Författare :Sunil Kumar Ramamoorthy; Jyrki Vuorinen; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; regenerated cellulose fibres; surface modification; alkali; silane; mechanical analysis; biocomposites; renewable resources; Resursåtervinning; Resource Recovery;

    Sammanfattning : Biocomposites have been developed to address the sustainability issues of nonrenewableresource based materials. These composites are often produced by reinforcing natural fibres in petroleum based thermoset resins or thermoplastic polymers. LÄS MER

  7. 5. Strengthening of timber structures with flax fibres

    Författare :Alann Andre; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER
