1. On Bicompositional Correlation
Sammanfattning : A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. LÄS MER
2. Spectroscopy of Stable and Radioactive Negative Ions
Sammanfattning : Negative ions are unique quantum systems which are of fundamental interest within the field of atomic physics due to the importance of the electron correlation in their creation, stability, and existence. Properties of these ions, such as the electron affinity, i.e. LÄS MER
3. Negative Ions Interacting with Photons and Electrons
Sammanfattning : Negative ions are atoms or molecules where an extra electron is bound to neutral system. The nature of negative ions differs fundamentally from neutral and positive systems. The induced dipole potential responsible for the binding of the extra electron supports only a few bound states with relatively small binding energies. LÄS MER
4. Spectroscopic studies of the negative state of atoms
Sammanfattning : Negative ions are of fundamental interest in atomic physics due to the enhanced importance of the electron correlation. In this thesis new spectroscopic methods have been developed and then applied to study the nature of atomic negative ions. LÄS MER
5. Myocardial Topical Negative Pressure
Sammanfattning : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. LÄS MER
