  1. 6. Fibre flow mechanisms

    Författare :Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. LÄS MER

  3. 7. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Författare :Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Sammanfattning : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

  4. 8. Mechanisms and Inhibition of EF-G-dependent Translocation and Recycling of the Bacterial Ribosome

    Författare :Anneli Borg; Måns Ehrenberg; Ruben Gonzalez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein synthesis; Elongation factor G; Translocation; Ribosome recycling; Fusidic acid; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : The GTPase elongation factor G (EF-G) is an important player in the complex process of protein synthesis by bacterial ribosomes. Although extensively studied much remains to be learned about this fascinating protein. LÄS MER

  5. 9. Regulation of Elovl and fatty acid metabolism

    Författare :Annelie Brolinson; Anders Jacobsson; Jaap Keijer; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fatty acid metabolism; fatty acid elongation; Physiology; Fysiologi; Physiology; fysiologi;

    Sammanfattning : Fatty acids are important regulators in the control of mammalian energy homeostasis. They are ingested in the diet but a significant amount are also endogenously produced by de novo lipogenesis. LÄS MER

  7. 10. A molecular chaperone that governs membrane contact sites and lipid metabolism

    Författare :Sergi Tosal Castaño; Sabrina Büttner; W. Mike Henne; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yeast; nucleus-vacuole junctions; proteostasis; unfolded protein response; fatty acid elongation; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Transmembrane proteins represent almost one third of the total cellular proteome, and the majority of them requires translocation into the endoplasmic reticulum (ER) to be folded, sorted and transported to their final subcellular destination. High translational rates during exponential cell growth result in a massive influx of immature proteins into the ER, requiring rapid and accurate folding. LÄS MER
