1. 21. Palsa Growth and Decay in Northern Sweden : Climatic and Environmental Controls

   Författare :Frieda S. Zuidhoff; Jonas Åkerman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; ground thermal properties; palsas; permafrost degradation; peat porosity; Sweden; vegetation.; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

   Sammanfattning : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. LÄS MER

5. 24. Radon and its decay products in housing : estimation of the radon daughter exposure to the Swedish population and methods for evaluation of the uncertainties in annual averages

   Författare :Gun Astri Swedjemark; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Methods have been worked out for evaluation of the uncertainties due to temporal variations in the annual averages for the concentrations of radon-222 (radon) and radon daughters (RnD) indoors. These methods have been applied to the results from long-term measurements of radon in a few houses. LÄS MER

7. 25. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique

   Författare :Karin Andgren; Bo Cederwall; Paul Nolan; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion reactions; multi-detector arrays; recoil separator; in-beam gamma-ray spectroscopy; high spin states; lifetime measurements; recoil-decay tagging; nuclear shape; Nuclear physics; Kärnfysik;

   Sammanfattning : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. LÄS MER
