  1. 1. Mass-Transport through Interfaces

    Author : Sofie Gårdebjer; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly lactide-co-glycolide acid ; cellulose; interfaces; poly lactic acid ; poly 3-hydroxybutyrate ; permeability; diffusion cells; polyethylene; mass-transport; ethylene acrylic acid;

    Abstract : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. READ MORE

  2. 2. Turbulent and neoclassical transport in tokamak plasmas

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Istvan Pusztai; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Abstract : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. READ MORE

  3. 3. Mass and Heat Transport in Dryer Fabrics - Experiments and Modelling

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Simon Smrtnik; Lund University.; Lunds universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transport; dryer fabric design; fabric parameters; mass transport; condensation;

    Abstract : A dryer fabric is used in the multi-cylinder dryer in order to improve the runnability of the web and to establish proper contact between the web and the hot cylinder, thus improving the heat transport. The dryer fabric separates the hot and moist paper from the ambient drying air and significantly influences the mass and heat transport. READ MORE

  4. 4. Mass Transport in Apple Tissue: Effects of Tissue Structure and Osmotic Processing Conditions

    University dissertation from Nikolaos E. Mavroudis, Unilever Research at Colworth, Sharnbrook, Bedford, MK441LQ, UK

    Author : Nikolaos Mavroudis; Lund University.; Lunds universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; drying; porosity; shrinkage; cell vitality; apple structure; apple; osmotic processing; mass transport; mass transport mechanisms;

    Abstract : Osmotic processing can be a very useful processing step in today’s food industry enabling the production of high quality natural food ingredients out of plant tissues. The maintenance of high product quality is quite product specific with regard to quality attributes. These attributes include fresh/like appearance, taste, texture and composition. READ MORE

  5. 5. Diffusive Mass Transport of Ions in Wood

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Reddysuresh Kolavali; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; wood; mass transport; impregnation;

    Abstract : Understanding the conditions that control the mass transfer of various chemicals/ions in wood is of great importance when it is subjected to various processes. Homogeneous impregnation with chemicals/ions, for example, increases the uniformity of the treatments to which the wood is subjected, reduces reaction times and may increase the yield of the final products.
