  1. 11. On Distributed Control-by-Wire Systems for Critical Applications

    Författare :Roger Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-triggered communication; fault-tolerance; distributed systems; dependable systems; inherent redundancy; control-by-wire;

    Sammanfattning : The implementation of closed loop control systems is an important field for the exploitation of embedded real-time computer systems. One can find a particularly interesting class of closed loop control applications within vehicle dynamics control. LÄS MER

  3. 12. Overcoming the Mass Transport Limitations of Dye-Sensitised Solar Cells : Towards highly efficient and robust alternative redox mediator electrolyte DSSCs

    Författare :Roger Jiang; Gerrit Boschloo; Erik Johansson; Anders Hagfeldt; Frédéric Sauvage; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitised solar cell; dye-sensitized solar cell; photoelectrochemical cell; cobalt tris bipyridine ; mass transport; photocurrent transients;

    Sammanfattning : Dye-sensitised solar cells (DSSCs) have been subject to decadelong research interest, and may have some potential niche market applications. Recently, major advances in power conversion efficiencies have been achieved following the transition to cobalt polypyridine based redox mediators. LÄS MER

  4. 13. Human mononuclear phagocytes : Production of reactive oxygen species generated by the NADPH oxidase

    Författare :Agneta Johansson; Roger Sundler; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Human professional phagocytes constitute the first line of defence against invading microorganisms. With a membrane-bound enzyme system, the NADPH oxidase, these cells generate bactericidal metabolites. Activation of NADPH oxidase results in a generation of reactive oxygen species, e.g. LÄS MER

  5. 14. Förhållandet mellan intern skattelagstiftning och skatteavtal : särskilt om företräde för interna skatteregler

    Författare :Alexandra Johansson; Roger Persson Österman; Peter Melz; Bertil Wiman; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conflict of law; distributive rules; double taxation; dualism; golden rule; method article; non-aggravation; tax avoidance; tax claim; tax treaty; tax treaty override; taxing rights; Legal Science; specialisation Finacial Law; rättsvetenskap med inriktning mot finansrätt;

    Sammanfattning : This thesis addresses the relationship between domestic tax law and tax treaties in a Swedish context, particularly with the purpose of clarifying when the legal consequences of domestic tax law are to prevail over those in tax treaties. The question of primacy arises due to domestic law and tax treaties often apply to the same situation, while providing for different legal consequences. LÄS MER

  7. 15. Profilin:actin in cell motility : A search for profilin:actin binding proteins

    Författare :Thomas Johansson; Roger Karlsson; Björn Öbrink; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; profilin; actin; Cell biology; Cellbiologi;

    Sammanfattning : The profilin:actin complex is a major source of actin for actin filament growth in vivo. A number of proteins regulating either profilin or actin has been described since profilin:actin was isolated during the 1970s. Since then, profilin and actin and their binding partners have been intensively studied. LÄS MER
