  4. 2. Cell Membrane Homeostasis in Mammals - The roles of ADIPOR2 and TLCD1 & 2

    Author : Henrik Palmgren; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; Membrane fluidity; Membrane homeostasis; Dietary lipids; Phospholipids; Genetics; Lipotoxicity; Lipidomics; ADIPOR2; TLCD1; TLCD2;

    Abstract : Ten nanometers. That is the approximate thickness of the plasma membrane that separates the extracellular space from the entire cellular machinery. An asymmetrical bilayer consisting of predominantly phospholipids in which proteins and carbohydrates are anchored and exert their function. READ MORE

  5. 3. Membrane Filtration of Lignocellulosic Materials: In situ Monitoring of Membrane Fouling Using Fluid Dynamic Gauging

    Author : Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood components; Membrane fouling; Fluid dynamic gauging; Cross-flow filtration;

    Abstract : The transition of process industries from utilizing fossil-based resources to bio-based ones necessitates energy-efficient and selective operations. One practical operation that can be employed for processing streams containing lignocellulosic biomass, such as forest and agricultural residues, is membrane separation. READ MORE

  6. 4. Electropermutation assisted by ion-exchange textile : removal of nitrate from drinking water

    Author : Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion-exchange textile; Ion-exchange membrane; Electropermutation; Electroextraction; Electrodialysis; Electrodeionisation; Modeling; Conducting spacer; Nitrate removal; Water treatment; Water dissociation; Fluid mechanics; Strömningsmekanik;

    Abstract : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE

  7. 5. Membrane Filtration of Wood Components − Investigation of Fouling Layer Characteristics using Fluid Dynamic Gauging

    Author : Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid dynamic gauging; wood components; cross-flow filtration; steam explosion; microcrystalline cellulose; membrane fouling;

    Abstract : As process industries transition from using fossil-based to bio-based resources, energy-efficient and highly selective operations will be required to process lignocellulosic biomass. Membrane separation, as a highly efficient operation, can be employed in the fractionation and dewatering of streams containing lignocellulosic biomass. READ MORE
