    Sammanfattning : Únětice kulturens roll när det kommer till formandet av bronsåldern i Europa kan inte överskattas. Uppkomsten och existensen av denna originella, utvidgande och dynamiska population markerar en av de mest intressanta tidpunkterna i europeisk förhistoria, tidpunkten då en era avslutas och en ny tar vid.

    Sammanfattning : The history of Holocene vegetation in western Estonia and the West Estonian Archipelago is described. Early Holocene sea level changes in the area are reconstructed, and human impact on the vegetation during the Late Holocene is discussed West Estonia was divided into five study areas (Rummu-Maardu, Mustjärve, Velise-Kiilaspere, Tôstamaa Peninsula, and northern Saaremaa in the West Estonian Archipelago, from north to south).

  5. 24. Analysis of cardiac cell turnover in humans by radiocarbon dating and mathematical modeling

    Författare :Sofia Zdunek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease is the largest cause of morbidity and mortality in the Western World. Disease progression often involves a loss of contracting cells, cardiomyocytes, which leads to cardiac failure and the need for heart transplantation with time. LÄS MER

  7. 25. Setting the Holocene clock using varved lake sediments in Sweden

    Författare :Lovisa Zillén; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; Physical geography; tephrochronology; palaeomagnetic secular variations; radiocarbon time-scale; Holocene varved lake sediments; varve chronology; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : The aim of this thesis was to study annually laminated (varved) Holocene lake sediment in Sweden, their formation and their potential as chronological and palaeoecological archives. Five lakes with continuous Holocene varved lake sediment sequences in northern (Västerbotten) and west central Sweden (Värmland) were investigated. LÄS MER
