16. Experimental Studies of the Neutron Deficient Atomic Nuclei 88Ru and 87Tc, and the Diagonalization of the General Pairing Hamiltonian
Sammanfattning : This doctoral thesis consists of two parts: the experimental study of the neutron-deficient atomic nuclei 88Ru and 87Tc, and the computational study on the diagonalization of general pairing Hamiltonian. In the first part, which constitutes the main content of the thesis, the low-lying excited states in the N = Z nucleus 88Ru and N = Z + 1 nucleus 87Tc were studied via fusion-evaporation reactions induced by 115 MeV 36 Ar ions bombarding6 mg/cm 2 thick metallic 54 Fe target foils at the Grand Accélérateur Nationald’Ions Lourds (GANIL), Caen, France.

17. Isotopes as Mechanism Spies : Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects
Sammanfattning : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

18. Selection of Decentralized Control Configuration for Uncertain Systems
Sammanfattning : Industrial processes nowadays involve hundreds or more of variables to be maintained within predefined ranges to achieve the production demands. However, the lack of accurate models and practical tools to design controllers for such large processes motivate the engineers/practitioners to break the processes down into smaller subsystems and applying decentralized controllers.

19. Proteins influencing the integrity of meiotic chromosome dynamics
Sammanfattning : Aneuploidy (trisomy or monosomy) is the leading genetic cause of human pregnancy loss and results from aberrant meiotic chromosome segregation. Accurate segregation of meiotic chromosomes depends on extensive pairing (called synapsis) and recombination between them. LÄS MER
20. Correlations in Finite Fermi Systems - Semiclassics and Shell Structure
Sammanfattning : This dissertation investigates correlations in finite Fermi systems. The atomic nuclei is the mainly studied system but also other systems, like superconducting metallic grains and cold Fermionic gases are considered. The dissertation comprises of five original papers. LÄS MER
