  2. 16. Solar Activity Changes at the End of the Last Ice Age - Influences on Climate and Applications for Dating

    Author : Florian Adolphi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solar Activity; 10Be; 14C; radiocarbon calibration; time scale; geochronology; paleoclimate; ice cores; tree rings; IntCal; cosmogenic radionuclides;

    Abstract : Throughout its history Earth experienced a variety of natural climate changes. By investigating their spatial and temporal evolution we can increase the understanding of the mechanisms and dynamics underlying natural climate change and improve our general comprehension of the climate system.

  4. 17. Exploring the limitations of 14C bomb-pulse dating on human tissue samples

    Author : Elisavet Georgiadou; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bomb-pulse dating; human tissues; stable isotope analysis;

    Abstract : The aim of this work, which will be part of the PhD work of the author of this report, was to evaluate the precision and accuracy expected from bomb-pulse dating of human tissue, focusing on the uncertainties introduced by variation in 14C in the human diet. Such variations may be caused by releases from nuclear installations, hospitals and laboratories using 14C, use of fossil fuels as well as variations in the type of diet consumed (e. READ MORE

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

    Author : Sofia Zdunek; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE

  6. 19. On Death in the Mesolithic : Or the Mortuary Practices of the Last Hunter-Gatherers of the South-Western Iberian Peninsula, 7th–6th Millennium BCE

    Author : Rita Peyroteo Stjerna; Kjel Knutsson; Mariana Diniz; Liv Nilsson Stutz; Clive Bonsall; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; death; Late Mesolithic; hunter-gatherers; social memory; place; burial practices; mortuary ritual; historical process; south-western Iberian Peninsula; archaeothanatology; radiocarbon dating and Bayesian analysis; stable isotopes carbon and nitrogen ; shell middens; museum collections; Archaeology; Arkeologi;

    Abstract : The history of death is entangled with the history of changing social values, meaning that a shift in attitudes to death will be consistent with changes in a society’s world view.Late Mesolithic shell middens in the Tagus and Sado valleys, Portugal, constitute some of the largest and earliest burial grounds known, arranged and maintained by people with a hunting, fishing, and foraging lifestyle, c 6000–5000 cal BCE.

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

    Author : Lovisa Zillén; Kvartärgeologi; []
    Keywords : 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;

    Abstract : 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. READ MORE
