  1. 16. Bending, Twisting and Turning : Protein Modeling and Visualization from a Gauge-Invariance Viewpoint

    Författare :Martin Lundgren; Antti Niemi; Jørgen Ellegaard Andersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; discrete frenet frame; solitons; protein visualization; Physics and Astronomy specializing in Theoretical Physics; Fysik och astronomi med inriktning mot teoretisk fysik;

    Sammanfattning : Proteins in nature fold to one dominant native structure. Despite being a heavily studied field, predicting the native structure from the amino acid sequence and modeling the folding process can still be considered unsolved problems. In this thesis I present a new approach to this problem with methods borrowed from theoretical physics. LÄS MER

  3. 17. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage

    Sammanfattning : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. LÄS MER
