    Sammanfattning : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. LÄS MER

  3. 3. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Ibrahim Elgali; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

    Sammanfattning : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

    Sammanfattning : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. LÄS MER

  5. 5. People of the Dolmens and Stone Cists An archaeogenetic Investigation of Megalithic Graves from the Neolithic Period on Gotland

    Detta är en avhandling från Lund Observatory, Lund University

    Författare :Magdalena Fraser; Kjel Knutsson; Mattias Jakobsson; Paul Wallin; Anders Götherström; Per Åke Persson; []
    Nyckelord :HUMANIORA; HUMANITIES; archaeology; aDNA; ancient genomics; archaeogenetics; mtDNA; osteology; radiocarbon dating; Strontium; Carbon; Nitrogen; TRB; PWC; BAC; CWC; dolmen; stone cist; population demography; diet; mobility; cultural duality; admixture; kinship; Neolithic period; Early Bronze Age; Europe; Baltic Sea area; Scandinavia; Gotland; Molekylär genetik; Molecular Genetics;

    Sammanfattning : The study of ancient genomics of pre-historic human remains has in recent years offered unprecedented knowledge regarding pre-historic migration and population structure on the European continent which has fundamentally altered the current views in the archaeological community. However, the merging of the two fields, archaeology and genetics, is still in its infancy and much work is still needed in order for these fields to integrate. LÄS MER
