  2. 16. Autoproteolysis accelerated by conformational strain - a novel biochemical mechanism

    Author : Denny Johansson; Göteborgs universitet; []
    Keywords : SEA domain; autoproteolysis; MUC1; conformational strain; protein folding;

    Abstract : Natural fragmentation of polypeptide chains by autoproteolysis occurs in a number of protein families. It is a vital step in the maturation of several enzymes and in the formation of membrane-associated mucins that constitute a part of the protective mucus barrier lining epithelial cells. READ MORE

  4. 17. Physical and psychosocial occupational strain

    Author : Gunvor Gard; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Sjukgymnastik;

    Abstract : This monography thesis is based on five empirical studies of physical and psychosocial occupational strain in working life. The first three studies concern the working environment of crane couplers. READ MORE

  5. 18. Microscopic Theory of Externally Tunable Exciton Signatures of Two-Dimensional Materials

    Author : Maja Feierabend; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localized states; density matrix formalism; magnetic field; transition metal dichalcogenides; Bloch equations; organic inorganic heterostructures; dark excitons; strain;

    Abstract : Atomically thin transition metal dichalcogenides (TMDs) are in the focus of current research due to their efficient light-matter interaction and the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of bright and optically inaccessible dark excitonic states. READ MORE

  6. 19. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Author : Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Abstract : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. READ MORE

  7. 20. Fetal Cardiac Function and Venous Circulation - Experiences with Velocity Vector Imaging

    Author : Charlotte Dahlbäck; Urogynekologi och reproduktionsfarmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pregnancy; fetus; strain; speckle tracking; cardiac function; umbilical vein; venous; ductus venosus; Doppler;

    Abstract : Placental dysfunction resulting in intrauterine growth restriction (IUGR) is a common complication of pregnany and severe IUGR, with ensuing fetal hypoxia is an important cause of perinatal mortality and morbidity. Doppler studies of fetal and maternal vessels are routinely used for fetal surveillance and alterations in fetal venous blood flow has been demonstrated as a late sign of fetal compromise. READ MORE
