  2. 1. Atomic Electrons as Sensitive Probes of Nuclear Properties and Astrophysical Plasma Environments : A Computational Approach

    Author : Asimina Papoulia; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2021:Papoulia; Computational atomic structure; Relativistic atomic theory; Transition probabilities; Abundance analysis; Landé g­-factors; Hyperfine structure; Nuclear quadrupole moments; Isotope shift; Field shift; Nuclear deformation;

    Abstract : This thesis deals with the relativistic modeling of atoms and ions. To interpret the stellar spectra and gain more insight from astrophysical observations, the underlying processes that generate the spectra need to be well understood and described. READ MORE

  4. 2. Extending the nuclear cranking model to tilted axis rotation and alternative mean field potentials

    Author : Peter Olivius; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; classical mechanics; gravitation; statistical physics; Kärnfysik; Nuclear physics; kvantmekanik; relativitet; statistisk fysik; termodynamik; thermodynamics; klassisk mekanik; Matematisk och allmän teoretisk fysik; Nuclear Structure; Tilted axis rotation; Mathematical and general theoretical physics; quantum mechanics; relativity; Fysicumarkivet A:2004:Olivius;

    Abstract : The nuclear model for three dimensional cranking is extended to include a generalization of the Strutinski renormalization procedure from principal axis cranking to cranking about an tilted axis. A new computer code has been written for realistic, full-scale calculations within the three dimensional cranking model. READ MORE

  5. 3. On the Simulation of Progressive Deformation in Nuclear Piping

    Author : Andreas Gustafsson; Jan Granlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : In this thesis the performance of different constitutive models in ratchet simulation is investigated. Ratcheting is accumulated plastic strains which may occur when a structure is subjected to a constant load in combination with cyclic loading. READ MORE

  6. 4. Magnetic Resonance Imaging of Myocardial Deformation and Scarring in Coronary Artery Disease

    Author : Johan Kihlberg; Jan Engvall; Tino Ebbers; Anders Persson; Åse Johnsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Although improved treatments have reduced the rates of acute complications from myocardial infarction, sequelae such as heart failure and sudden death threaten the future wellbeing of those patients. Secondary prevention after myocardial infarction is related to cardiovascular risk factors and the effect of the infarct on left ventricular function. READ MORE

  7. 5. Octupole collectivity and E1 moments in neutron rich nuclei

    Author : Axel Lindroth; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Abstract : Spectroscopy of short-lived fission and reaction products has allowed a detailed structural study of neutron rich nuclei just above above 132Sn and 208Pb, respectively. The low-energy structures of 140Xe and 143Ba as well as a handful of neutron rich nuclei in the actinide region were examined. READ MORE
