  1. 21. Mechanical modelling of blade forming and drainage of flocculated suspensions

    Författare :Claes Holmqvist; Anders Dahlkild; Douglas Bousfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; blade forming; pressure distribution; interaction; suction; drainage; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. LÄS MER

  3. 22. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry

    Författare :Henric Svensson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood leachate; Log yard runoff; Stormwater; Toxicity; Artemia salina; Vibrio fischeri; Constructed wetlands; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER

  4. 23. Laboratory measurements of airborne emissions from car brakes for clean air

    Författare :Guido Perricone; Ulf Olofsson; Fulvio Amato; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive brake; non-exhaust emissions; inertia brake dynamometer; airborne particles; PM10; PN; isokinetic sampling; Rebrake; volatiles; real driving cycle; car brake emission factors; running-in.; Bilbroms; icke-avgasemissioner; skivbromsdynamometer; luftburna partiklar; PM10; PN; isokinetisk provtagning; Rebrake; volatiler; verkliga körcykler; emissionsfaktorer; in-körning.; Machine Design; Maskinkonstruktion;

    Sammanfattning : Brake systems are used to safely stop vehicles. The brake pads are pressed against the brake disc, transforming the kinetic energy of the vehicle into heat to be dissipated. LÄS MER

  5. 24. Regulation of thromboinflammation in therapeutic medicine : Special focus on surface coating strategies

    Författare :Sana Asif; Bo Nilsson; Christine Skerka; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Biomaterials are an integral part of modern health care and offer potential treatment modalities to diseases and conditions otherwise intractable. However, the critical issue herein is incompatibility reactions. LÄS MER

  7. 25. Fluid flow through and deformation of wood fiber networks

    Författare :Patrik Pettersson; Veronique Michaud; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. LÄS MER
