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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples

    Sammanfattning : The testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. LÄS MER

  3. 3. External and Intrinsic Signatures in Human Teeth to Assist Forensic Identification Work

    Författare :Kanar Alkass; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : In forensic medicine, dead victim identification constitutes an important task for forensic professionals including forensic pathologists, anthropologists, and odontologists. If no clues are at hand regarding the identity of the deceased, whether it is a victim of a mass disaster or a suspect homicide case, it is vital to know when a person died, and to know the sex and age of the decedent in order to limit the search for possible matching persons.

  4. 4. Impact of alcohol and drug abuse on hippocampal neurogenesis in humans

    Författare :Gopalakrishnan Dhanabalan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Hippocampus is one of the few brain regions in which adult neurogenesis is known to occur. Adult neurogenesis in the hippocampus is considered to be important for higher cognitive function, most notably in memory processes and mood regulation. Alcohol abusers are often diagnosed with memory dysfunction. LÄS MER
