  1. 6. Novel and ancient technologies for heating and cooling buildings

    Författare :Sofiane Amara; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The basic issue of this thesis concerns one of the fundamental problems of the future of our society: How to meet the energy requirements for a large and growing world population while preserving our environment? This question is important for the world and the answers are complex and interwoven.Conventional energy sources, fossil and fissile, are polluting in the present and in the future: they erode the environment and their resources are limited.

  3. 7. 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

  4. 8. Reconstructing the Human Past using Ancient and Modern Genomes

    Författare :Pontus Skoglund; Mattias Jakobsson; John Novembre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; paleogenomics; human evolution; Evolutionary Genetics; Evolutionär genetik;

    Sammanfattning : The study of DNA variation is one of the most promising avenues for learning about the evolutionary and historical past of humans and other species. However, the difficulty associated with obtaining DNA directly from ancient remains have for long kept genomic studies of population history trapped in time; confined to interpreting patterns of modern-day variation without direct historical observations.

  5. 9. Novel methods of tandem mass spectrometry in life sciences

    Författare :Mohammadhassan Gharibi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mass spectrometry (MS) is a powerful analytical technique widely employed for isotopic analysis and species identification in numerous research fields. Isotopic analysis involves precisely measuring stable isotopes within a sample, offering valuable insights into its origin, environment, and biological processes. LÄS MER

  7. 10. Medium chain dehydrogenases/reductases : alcohol dehydrogenases of novel types

    Författare :Annika Norin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alcohol dehydrogenase; Nicotinoproteins; Structural interpretations; Functional properties; Molecular evolution.;

    Sammanfattning : The medium chain dehydrogenase/reductase (MDR) superfamily is separated into at least eight families, of which the dimeric alcohol dehydrogenase (ADH) is one. Including species variants, close to 1000 MDR forms have been characterized. LÄS MER
