  1. 1. Open Government Data as a Reform and Ecosystem : A conceptual framework for evolution and health

    Författare :Jonathan Crusoe; Ulf Melin; Gustaf Juell-Skielse; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Open Government Data; Reform; Ecosystem; Health; Evolution; Impediment; Barrier; Risk; Enricher; User; Seeker; Provider; Publisher; Öppna data; ekosystem; reform; hälsa; evolution; hinder; barriär; risk; berikare; användare; sökare; medborgare; tillgängliggörare; publicerare;

    Sammanfattning : Introduction: This doctoral thesis in Information Systems disentangles the interplay of an OGD reform and an OGD ecosystem. Open government data (OGD) refers to data shared by public organizations, in the role of providers, following certain principles for anyone to reuse. LÄS MER

  3. 2. Directed Evolution of Glutathione Transferases with Altered Substrate Selectivity Profiles : A Laboratory Evolution Study Shedding Light on the Multidimensional Nature of Epistasis

    Författare :Wei Zhang; Bengt Mannervik; Bengt-Harald Jonsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glutathione transferase; azathioprine; directed evolution; semi-rational design; catalytic mechanism; saturation mutagenesis; reduced amino acid alphabets; molecular docking; protein evolution; multivariate data analysis; epistasis; fitness landscape; evolutionary trajectories; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Directed evolution is generally regarded as a useful approach in protein engineering. By subjecting members of a mutant library to the power of Darwinian evolution, desired protein properties are obtained. Numerous reports have appeared in the literature showing the success of tailoring proteins for various applications by this method. LÄS MER

  4. 3. Skapa plats i landskapet : tidig- och mellanneolitiska samhällen utmed två västskånska dalgångar

    Författare :Magnus Andersson; Lunds universitet; []

    Sammanfattning : This dissertation deals with Early and Middle Neolithic societies in a valley landscape in western Scania, in the southern part of Sweden. Several archaeological excavations conducted by the National Heritage Board have revealed a great number of Neolithic remains in this region. LÄS MER

  5. 4. Cenozoic landscape evolution in northern Sweden : Geomorphological interpretation within a GIS-framework

    Författare :Karin Ebert; Clas Hättestrand; Paul Bishop; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Long-term geomorphology; northern Sweden; base-level surface; inselbergs; digital elevation models; field observations; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Sammanfattning : The large-scale bedrock landscape in northern Sweden has a complex evolution history of planation, uplift, transgression, burial, weathering, and erosion. The aim of this thesis is to examine the long-term development of the area. Terms for base-level surfaces in the area are defined. LÄS MER

  7. 5. Where our feet have taken us : Examples of human contact, migration, and adaptation as revealed by ancient DNA

    Författare :Alexandra Coutinho; Mattias Jakobsson; Helena Malmström; Carina Schlebusch; Tom Gilbert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human demography; migration; adaptation; human contact; ancient DNA; human evolution; African prehistory; Scandinavian prehistory; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : In spite of our extensive knowledge of the human past, certain key questions remain to be answered about human prehistory. One involves the nature of cultural change in material culture through time from the perspective of how different ancient human groups interacted with one another. LÄS MER
