  1. 11. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases

    Författare :Fredrik Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; morphology; taxonomy; Systematic botany; plant mitochondria; NAD P H dehydrogenases; cold treatment; complex I; light dependence; antimycin a; alamethicin;

    Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER

  4. 13. Microscopic Modeling and Simulation of Pedestrian Traffic

    Författare :Fredrik Johansson; Jan Lundgren; Anders Peterson; Andreas Tapani; Winnie Daamen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Walking is an environmentally friendly and important mode of transportation. It constitutes the first and last part of almost any trip, regardless of what the main mode of transport is, and is especially important in connection to public transport trips. LÄS MER

  5. 14. The synthesis of chiral bidentate (N,N), (N,P) and (N,O) ligands and their use in metal-mediated asymmetric carbon-carbon bond formation

    Författare :Fredrik Johansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis covers three projects based on the metal-mediated formation of new chiral centers in the prescence of chiral ligands. The first project, involving (N,N)- ligands, concerns the synthesis of some (C2-symmetric bis(aziridine) ligands and the use of these in the addition of organolithium reagents to N-aryl protected imines leading to enantioselectivities of up to 89%.

  7. 15. Towards a sustainable mobility paradigm? An assessment of three policy measures

    Författare :Fredrik Johansson; Greger Henriksson; Jonas Åkerman; Pelle Envall; Sprei Frances; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable mobility paradigm; Social Practice Theory; Mobility services; flexible parking requirements; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Transportation and mobility are important components in the organisation and structure of people´s daily activities, but the transport sector has considerable environmental impacts, e.g. greenhouse gas emissions and land use. LÄS MER
