    Sammanfattning : The development and improvement of the functionality of metal oxides in heterogeneous catalysis and other surface chemical processes can greatly benefit from an atomic-level understanding of the surface chemistry. Atomistic calculations such as quantum mechanical (QM) calculations and molecular dynamics (MD) simulations can provide highly detailed information about the atomic and electronic structure, and constitute valuable complements to experimental surface science techniques.

  3. 2. Den yngre järnålderns gravskick i Uppland : Framväxten av den arkeologiska bilden och en materialitet i förändring

    Författare :Jhonny Therus; Neil Price; Frands Herschend; Anders Kaliff; Alison Klevnäs; Uppsala universitet; []
    Nyckelord :Late Iron Age; Viking Age; burial practice; bridging practice; monument gravity; historical gravity; grave; memory; hǫrgr; amulet ring; cosmology; cremation; Christianization; settlement archaeology; mortuary behaviour; dispersed burial; Archaeology; Arkeologi;

    Sammanfattning : This thesis examines archaeological approaches to burials and changing mortuary practices during the Late Iron Age (c. 500-1100 AD) in central Eastern Sweden. Understanding the change in mortuary practices is fundamental to the study of the Late Iron Age. LÄS MER
