  1. 1. Cosmogenic radionuclides in environmental archives – A paleo-perspective on space climate and a synchronizing tool for climate records

    University dissertation from Lunds universitet

    Author : Florian Mekhaldi; [2018-12]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Comogenic radionuclides; 10Be; 36Cl; Solar energetic particles; Solar storms; Paleoclimate; Time-scales; Solar activity;

    Abstract : The Sun is the primary source for Earth’s climate system. Its fluctuations in irradiance are also known to have an impact on climate. In addition, changes in solar activity modulate the atmospheric production rates of cosmogenic radionuclides (e.g. READ MORE

  2. 2. Chlorine Cycling in Terrestrial Environments

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; [2016]

  4. 4. Disinhibitory and aggressive behavior in the rat. Neurohumoral mechanisms

    University dissertation from Göteborg

    Author : Anders I Svensson; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Effective pharmacological treatment for impulsive aggression and dysfunctional impulsive behavior is needed. These behavioral disturbences in man and impulsive-like and aggressive behavior in animals may involve serotonin (5-HT), noradrenaline (NA), GABAA receptors and steroid hormones, e.g. testosterone.

  5. 5. Improvement of the AMS-technique and applications to 3H and 59Ni Measurements

    University dissertation from Department of Physics, Lund University

    Author : Madis Kiisk; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accelerator mass spectrometry AMS ; development of AMS technique; 59Ni; tritium; Kärnfysik; Nuclear physics; Fysicumarkivet A:2003:Kiisk;

    Abstract : Accelerator mass spectrometry (AMS) is a highly sensitive technique for counting atoms. Its main advantage in comparison with radiometric methods is the smaller amount of sample required (by a factor of a thousand). The method has a high efficiency and requires only some ten mg of sample material. READ MORE
