    Abstract : The effects of self-consistency in the GW-approximation are studied. The $GWA$ is known to describe the electronic properties of a wide range of materials very well. However, the calculations made so far have not taken into account the issue of self-consistency, which is implied in the original formulation of the $GWA$. READ MORE

  4. 2. Wood Fungi and Forest Fire

    Author : Fredrik Carlsson; Bengt-Gunnar Jonsson; Mattias Edman; Svante Holm; Jacob Heilmann-Clausen; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Forest fires have been the major stand-replacing/modifying disturbance in boreal forests. To adapt to fire disturbance, different strategies have evolved. This thesis focuses on wood fungi, and the effect of forest fire on this organism group. READ MORE
