  1. 1. Preservation of Marine Reptile Soft Parts: Reconstructing the Life and Death of Ancient Leviathans

    Författare :Randolph De La Garza; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular paleontology; Taphonomy; Soft-tissues; Lagerstätten; Skin; Sea Turtle; Ichthyosaur; Fur Formation; Posidonia Shale; Paleobiology; Marine Reptiles;

    Sammanfattning : Marine reptiles constitute a diverse group of secondarily aquatic tetrapods that have inhabited the world’s oceans for the greater part of the last 250 million years. While certain large-scale anatomical changes have been observed through progressive alterations of their skeletal morphology (e.g. LÄS MER

  3. 2. Exceptional fossil preservation: implications for palaeobiology and taphonomy

    Författare :Miriam Heingård; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exceptional preservation; molecular palaeontology; palaeobiology; taphonomy; braincase; cuticle; fish larvae; Fur Formation; Stolleklint Clay; melanin; systematics;

    Sammanfattning : Although fossils are relatively common in some sedimentary deposits, the majority consists of fragmented or distorted skeletal hard parts (such as shell and bones). However, in rare cases, special burial and diagenetic conditions have allowed a greater portion of the original anatomy to be incorporated into the fossil record. LÄS MER

  4. 3. People in Between : Ethncity and Material Identity, a New Approach to Deconstructed Concepts

    Författare :Charlotta Hillerdal; Frands Herschend; Johan Rönnby; Neil Price; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; ethnicity; materiality; cultural identity; cultural practice; Viking Age; Varangians; Russia; Métis; Canada; colonialism; post-colonial; Romantic philosophy; indigenous; Ruhnu; Estonia; authenticity; national identity; Viking Age towns; Scandinavia; town formation; discontinuity; Archaeology; Arkeologi; arkeologi; Archaeology; Östersjö- och Östeuropaforskning;

    Sammanfattning : In questions concerning ethnicity and cultural identity in prehistory, there is a great divide between the conclusions maintained on a theoretical level of discussion and the interpretations given to material remains, when these theories are practiced on the archaeological material. Inherited scientific and political structures, usage and ideas contribute to our understanding of ethnicity and the everyday use of the concept, and influence archaeological interpretations. LÄS MER

  5. 4. Magnetic bead-based isolation of biological therapeutic modalities

    Författare :Nils A. Brechmann; Véronique Chotteau; Nigel Titchener-Hooker; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic bead separation; Magnetic beads; Protein A; Protein G; Negative cell isolation; Monoclonal antibody; induced pluripotent stem cells; human mesenchymal stem cells; Allogenic cell therapy; Biomanufacturing; cell clarification; Biotechnology; Bioteknologi;

    Sammanfattning : Biopharmaceutical modalities, such as monoclonal antibodies or the less established cell therapies, are nowadays very important for the treatment of severe or incurable diseases. The manufacturing of such modalities is complex and costly, including the downstream processing, which is highly essential to ensure the safety and quality of the product. LÄS MER

  7. 5. Structural and biochemical insights into biosynthesis and degradation of N-glycans

    Författare :Tom Reichenbach; Christina Divne; David Drew; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-glycan; biosynthesis; degradation; glycosyltransferase; glycoside hydrolase; biofuel; enzyme; membrane protein; Bioteknologi; Biotechnology;

    Sammanfattning : Carbohydrates are a primary energy source for all living organisms, but importantly, they also participate in a number of life-sustaining biological processes, e.g. cell signaling and cell-wall synthesis. The first part of the thesis examines glycosyltransferases that play a crucial role in the biosynthesis of N-glycans. LÄS MER
