  1. 6. Calibrating integration : studies on status, culture, knowledge and cooperation in acquisitions

    Författare :Harun Emre Yildiz; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Acquisitions represent a common modus operandi of firm growth. Notwithstanding their lasting popularity, the majority of deals are reported to be unsuccessful. Given their prevalence and practical relevance, acquisitions have attracted scholarly interest from diverse academic disciplines and traditions. LÄS MER

  3. 7. Loops, Twists and String Vertices: The Sewing Approach to String Perturbation Theory

    Författare :R. Niclas Engberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : String theory provides the most promising candidate for a unified theory of all fundamental forces and a consistent quantum mechanical theory of gravity. String theory is, at present, defined through its perturbation expansion. There exists various methods for treating the string diagrams one of which is through the sewing of Reggeon vertices.

  4. 8. Towards International Chemical Safety : Taking Action on Persistent Organic Pollutants

    Författare :Henrik Selin; Loftsson Elfar; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Convention on Long-Range Transboundary Air Pollution CLRTAP ; persistent organic pollutants POPs ; regime analysis; social learning; Miljö; Föroreningar; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Persistent organic pollutants (POPs) have been subject to increased international ro-operation over that past decade. The first international effort to address POPs collectively as a distinet class of pollutants was made under the United Nations Economic Commission for Europe (UNECE) and within the framework of the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which geographically covers North America, Europe and the region of the former Soviet Union.

  5. 9. Problems and experiments in cone-beam tomography

    Författare :Jan Eriksson; Stefan Challer; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Two-dimensional detectors for cone-beam exposure are now introduced in medical as well as industrial computer tomography. This thesis starts with a review of basic 2D reconstruction algorithms and the first proposal for cone-beam tomography due to Feldkamp et al.Exact reconstruction is possible only if complete projection data are avail­ able.

  7. 10. Activity-dependent changes of synaptic transmission in a long-term perspective and processes involved

    Författare :Mikhail Dozmorov; Göteborgs universitet; []
    Nyckelord :synaptic plasticity; hippocampus; LTP; LTD; AMPA; NMDA; protein synthesis;

    Sammanfattning : Synaptic plasticity is an essential property of the central nervous system. It is thought torepresent a mechanism for memory aquisition, storage and recall. The most well studied forms ofsynaptic plasticity are homosynaptic NMDAR-dependent LTP and LTD in the hippocampus inducedby specific patterns of electrical stimulation. LÄS MER
