1. Cosmogenic radionuclides in environmental archives – A paleo-perspective on space climate and a synchronizing tool for climate records
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. Chlorine Cycling in Terrestrial Environments
Abstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

3. Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores
Abstract : During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. READ MORE

4. Accelerator Mass Spectrometry of 36Cl and 129I : Analytical Aspects and Applications
Abstract : Two long-lived halogen radionuclides (36Cl, T1/2 = 301 kyr, and 129I, T1/2 = 15.7 Myr) have been studied by means of Accelerator Mass Spectrometry (AMS) at the Uppsala Tandem Laboratory. The 36Cl measurements in natural samples using a medium-sized tandem accelerator (~1 MeV/amu) have been considered. READ MORE

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