  1. 21. Experimental Protein Dynamics and its Role in Predicting Protein Function

    Författare :Maja Jensen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biochemistry; Protein Dynamics; Protein Function;

    Sammanfattning : By studying proteins we learn about the processes that control life, such as important procedures in the body, diseases and eventually find more targeted cures for many diseases. Proteins are constantly being built up and decomposed in living organisms. Many proteins move and interact with other proteins or small molecules in the cell. LÄS MER

  3. 22. Radiation in simulations of high intensity laser-matter interaction

    Författare :Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma; nonlinear dynamics; particle-in-cell; Manley-Rowe; radiation reaction; synchrotron radiation;

    Sammanfattning : We consider electromagnetic waves propagating in plasmas, with two main themes covered. First nonlinear plasma theory and wave-wave interaction. Here a wave-wave symmetry, the Manley-Rowe relations, is used as a method of determining the physicality of modified plasma fluid equations. LÄS MER

  4. 23. Pushing methods for plasma simulations into the QED regime

    Författare :Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LWFA; nonlinear dynamics; plasma; Manley-Rowe; particle-in-cell; synchrotron radiation; radiation reaction;

    Sammanfattning : The interaction between a super-intense laser pulse, with intensity up to 10²² W/cm², and a plasma opens new regimes of physics, with new questions and more demand on existing numerical tools. Relativistic and quantum effects which are negligible for lower laser intensities become important and must be properly modelled to generate reliable predictions. LÄS MER

  5. 24. Financial Frictions and Firm Dynamics

    Författare :Erik Spector; Nils Gottfries; Stephen Bond; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: In light of the recent Great Recession, it has become painfully clear that financial factors are central to macroeconomic dynamics. This paper evaluates a micro-level financial friction which plays a central role in the theoretical literature on financial frictions, namely the external finance premium. LÄS MER

  7. 25. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation

    Författare :Charlotte Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium; allylic alkylation; η3-allyl palladium complexes; regioselectivity; PN-ligand; memory effects; dynamics; ligand effect; trans effects.;

    Sammanfattning : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. LÄS MER
