1. The Lure of Origins : An Inquiry into Human-Environmental Relations, Focused on the ”Neolithization” of Sweden
Sammanfattning : The purpose of this dissertation is to contribute to the discussion of the deeper meaning, in our contemporary context, of the ”neolithization” of Sweden. The basis for the investigation is twofold: * a critical examination of recent research reports dealing mostly with the Early Neolithic of (Middle) Sweden which shows, inter alia, that ”agriculture” was of marginal importance for a very long time from about 4000 BC onwards, while, at the same time, the idea of ”the transition to farming” dominates discourse.

3. Studies of PWO Crystals and Simulations of the p̅p →Λ̅Λ, Λ̅Σ0 Reactions for the PANDA Experiment
Sammanfattning : The thesis comprises investigations of two topics related to the PANDA experiment. The first part is dedicated to energy resolution and light yield uniformity studies of PWO crystals for the electromagnetic calorimeter. The second part of the thesis is dedicated to simulation studies of the p̅p→Λ̅Λ and the p̅p→Λ̅Σ0 channels. LÄS MER
4. Methods for the Assessment of Long-Lived Radionuclides in Humans Resulting from Nuclear Activities or Accidents - Fission track analysis of trace-amounts 239Pu and a copper hexacyanoferrate kit for monitoring radiocaesium
Sammanfattning : Fission track analysis (FTA) was developed to be applied to ultra-low levels of 239Pu in bioassay samples. An analytical protocol was established for the FTA processing. The detection limit was determined to 1.5 µBq and the calibration constant was 24 fission fragments per µBq 239Pu. LÄS MER
5. NMR Imaging of Flow and Perfusion using Hyperpolarized Nuclei: Theoretical Considerations and Application to Experimental Models
Sammanfattning : In the studies presented in this thesis, hyperpolarized tracers have been used for the study of macroscopic flow and capillary perfusion with magnetic resonance imaging. The feasibility of performing vascular studies using echo-planar imaging (EPI) and hyperpolarized 129Xe was investigated using xenon dissolved in ethanol prior to injection into a flow phantom.
