  1. 11. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis

    Författare :Jens Forsberg; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; proteolysis; Plant biochemistry; protease; two-component systems; protein kinase; protein phosphorylation; state transitions; light-harvesting antenna; photosynthesis; chloroplast;

    Sammanfattning : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. LÄS MER

  3. 12. Dissecting the photosystem II light-harvesting antenna

    Författare :Jenny Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; carotenoid; feedback de-excitation; fitness; LHC; NPQ; photosynthesis; state transitions; xanthophyll; Växtfysiologi; Plant physiology; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Sammanfattning : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

  4. 13. Structural Transitions in Helical Peptides : The Influence of Water – Implications for Molecular Recognition and Protein Folding

    Författare :Martin Lignell; Hans-Christian Becker; Kaare Teilum; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; protein folding; molten globule; time-resolved fluorescence spectroscopy; CD spectroscopy; molecular recognition; structure-function paradigm; Chemical physics; Kemisk fysik; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Fluctuations in protein structure are vital to function. This contrasts the dominating structure-function paradigm, which connects the well-defined three-dimensional protein structure to its function. However, catalysis is observed in disordered enzymes, which lack a defined structure. LÄS MER

  5. 14. Multicomponent superconductivity : Vortex matter and phase transitions

    Författare :Johan Carlström; Egor Babaev; Leo Radzihovsky; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Ginzburg Landau; field theory; Iron pnictide;

    Sammanfattning : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of super- conductors with multiple superconducting gaps, and possess many properties that set them apart from single component models. LÄS MER

  7. 15. Without mast, without sails, without compass : Non-traditional trajectories into higher education and the duality of the folk-market

    Författare :Reed T. Curtis; Klara Bolander Laksov; Max Scheja; Fredrik Hertzberg; Rie Thomsen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; educational trajectories; self-efficacy; collective efficacy; sociocultural history; Sweden; neoliberalism; education; university; school choice; career guidance; statist individualism; folkhem; transitions; pragmatism; late modernity; pedagogik; Education;

    Sammanfattning : In 1809, the trajectory of Swedish history and the identities associated with the country changed after Finland was lost to Russia. Swedish General von Döbeln explained that the loss left the nation "without mast, without sails, without compass." The research within this dissertation is not of war but of a similar sense of loss.
