  1. 16. Spatio-temporal genetic variation in wild animal and plant populations in Sweden and its relevance for conservation genetic monitoring

    Författare :Johan Charlier; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Human impact on the world’s ecosystems is massive, resulting in habitat destruction and fragmentation that strongly affects the future survival of non-human life forms. Typically, biodiversity loss at the genetic level is much less recognized as compared to the levels of species and ecosystems, and information on reduction of natural gene pools is frequently missing unless coupled with loss of an entire species.

  3. 17. Nucleic Acids: Innovative Methods for Recovery, Clarification and Purification

    Författare :Tiago Matos; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The importance of nucleic acids in pure form for preparative and analytical perspectives, have increased constantly, demanding the development of new and more efficient methods for their recovery and isolation. This thesis describes a series of different innovative methods for recovery and purification of these biomolecules. LÄS MER

  5. 19. Mesoscopic superconductivity : quasiclassical approach

    Författare :Marek Ožana; Andrei Shelankov; Dierk Rainer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesoscopic superconductivity; quasiclassical theory; boundary conditions; multi-layer structures; Gor kov equations; quasiclassical Green s function; Green s function on classical trajectories;

    Sammanfattning : This Thesis is concerned with the quasiclassical theory of meso-scopic superconductivity. The aim of the Thesis is to introduce the boundary conditions for a quasiclassical Green’s function on partially transparent interfaces in mesoscopic superconducting structures and to analyze the range of applicability of the quasiclassical theory.
