  1. 1. Phosphorylation in State Transition Less cause more effect

    Detta är en avhandling från University of Umeå : Department of Plant Physiology

    Författare :Jakob Damkjaer; Umeå universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Photoacclimation; State Transtion; LHCII Phosphorylation; Lhcb3; Lhcb6; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. LÄS MER

  4. 4. Numerical studies of transtion in wall-bounded flows

    Detta är en avhandling från Stockholm : KTH

    Författare :Ori Levin; KTH.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layer; suction; wall jet; streaks; waves; periodic disturbance; localized disturbance; turbulent spot; algebraic growth; exponential growth; stability; transition thresholds; transition prediction; PSE; DNS; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Sammanfattning : Disturbances introduced in wall-bounded flows can grow and lead to transition from laminar to turbulent flow. In order to reduce losses or enhance mixing in energy systems, a fundamental understanding of the flow stability and transition mechanism is important. LÄS MER

  5. 5. Theoretical Studies of Atomic Structure, Radiative Transitions and Interference Effects

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Martin Andersson; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Computational physics; Zeeman; Transition rate; Lifetime; Hyperfine structure; Interference; Atomic structure;

    Sammanfattning : Theoretical calculations concerning the advanced understanding of atomic structure and transitions has been performed for some atomic systems. The importance of different types of correlation depending on system has been investigated both using relativistic and non-relativistic quantum mechanics. LÄS MER
