  1. 11. Cytoarcheology : understanding cellular turnover in the human brain and heart

    Författare :Ratan Dev Bhardwaj; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The total number of cells within a human being increases dramatically during growth, yet certain organs are thought to have distinct differences within this regard. Just as cells may be added to an organ, cells may die also, and these dynamics of cellular addition and cellular death are known as cellular turnover. LÄS MER

  3. 12. Beyond Pigou: Climate Change Mitigation, Policy Making and Distortions

    Författare :Alex Schmitt; John Hassler; Massimo Tavoni; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; climate-economy modeling; income taxation; time consistency; political instability; Economics; nationalekonomi;

    Sammanfattning : This thesis consists of three essays.The first essay, “Optimal Carbon and Income Taxation”, analyzes carbon taxation while taking into account that taxes are set by national policy makers. I add two features, namely distortionary income taxation and lack of commitment to future policies, to a standard climate-economy model. LÄS MER

  4. 13. The Heart and Soul of the Party : Candidate Selection in Ghana and Africa

    Sammanfattning : The ambition of this book is to shed light on the power dynamics within African political parties through studying how different parties select their candidates for parliamentary elections. Having control over who should represent the party in elections is often considered an important factor in the distribution of power. LÄS MER

  5. 14. Large carnivore population turnover and ecological change during the Late Quaternary

    Författare :Erik Ersmark; Love Dalén; Jennifer Leonard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : The cave lion (Panthera spelaea), the grey wolf (Canis lupus) and the brown bear (Ursus arctos) all shared an intercontinental distribution across the northern hemisphere during most of the Late Quaternary, and experienced repeated events of climate change. The cave lion went extinct at the end of the Pleistocene and although the wolf and the bear have survived until present day, recent human persecution has caused demographic bottlenecks and local extinctions.

  7. 15. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side

    Författare :Ulrika Flock; Pia Ädelroth; Simon de Vries; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; denitrification; nitric oxide reductase; heme copper oxidase superfamily; divergent member; proton transfer; electron transfer; single turnover; spectroscopy; periplasm; glutamate; proton pathway; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. LÄS MER
