  2. 1. Flow Field and Fibre Fractionation Studies in Hydrocyclones

    Author : Jonas Bergström; Bo Norman; Mark Martinex; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre suspension; fractionation; hydrocyclone; measurement technique; velocity measurement; shear forces; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Hydrocyclones can be used to fractionate fibres according to their papermaking potential. The obtained fractions typically differ in fibre wall thickness and/or degree of fibre treatment. Despite a multitude of potential application scenarios, the process has so far had little commercial success. READ MORE

  4. 2. Fibre flow mechanisms

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

    Abstract : 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. READ MORE

  5. 3. Computational Studies of Photobiological Keto-Enol Reactions and Chromophores

    Author : Olle Falklöf; Bo Durbeej; Patrick Norman; Luis Manuel Frutos Gaite; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents computational chemistry studies of keto-enol reactions and chromophores of photobiological signicance.The rst part of the thesis is concerned with two protein-bound chromophores that, depending on the chemical conditions, can exist in a number of dierent ketonic and enolic forms.

  6. 4. Photochemical properties of phytochrome and firefly luciferase chromophores: A theoretical study

    Author : Olle Falklöf; Bo Durbeej; Patrick Norman; Marcus Lundberg; Linköpings universitet; []
    Keywords : ;

    Abstract : This licentiate thesis presents computational chemistry studies on photochemical properties of phytochrome and firefly luciferase chromophores.Phytochromes are bilin-containing proteins that based on the ambient light environment regulate a number of physiological and developmental processes in bacteria, cyanobacteria, fungi and plants.
