1. Dynamics of complex magnetic systems
Sammanfattning : Dynamic magnetic properties of disordered and frustrated magnetic systems have beenexperimentally investigated utilising SQUID (Superconducting Quantum Interference Device)magnetometry. The studied systems are spin glasses, reentrant ferromagnets, reentrantantiferromagnets and diluted Ising antiferromagnets. LÄS MER
2. Cryoablation of cardiac arrhythmias
Sammanfattning : This thesis evaluates the safety and efficacy of cryoablation in supraventricular tachyarrhythmias. In Study I, the acute and long-term outcome of cryoablation therapy of typical atrioventricular nodal reentrant tachycardia (AVNRT) was studied in a large series of patients (n=312). LÄS MER
3. Formalizing life : Towards an improved understanding of the sequence-structure relationship in alpha-helical transmembrane proteins
Sammanfattning : Genes coding for alpha-helical transmembrane proteins constitute roughly 25% of the total number of genes in a typical organism. As these proteins are vital parts of many biological processes, an improved understanding of them is important for achieving a better understanding of the mechanisms that constitute life. LÄS MER
4. ATRIOVENTRICULAR CONDUCTION in Patients with Paroxysmal Supraventricular Tachycardias
Sammanfattning : This thesis concerns retrospective and prospective studies of the atrioventricular (AV) conduction properties in patients with cardiac arrhythmias. The objectives of the retrospective studies were to further delineate the sex distribution in patients with Wolff-Parkinson-White syndrome (WPW) and AV nodal reentrant tachycardia (AVNRT) and to determine the underlying mechanisms of the differences in sex distribution, to investigate the relationship between the conduction properties of normal and accessory AV pathway, and to evaluate their conduction properties with respect to accessory pathway location.

5. Fundamental Properties of Functional Magnetic Materials
Sammanfattning : Magnetic properties of powders, thin films and single crystals have been investigated using magnetometry methods. This thesis provides analysis and conclusions that are supported by the results obtained from spectroscopic and diffraction measurements as well as from theoretical calculations. LÄS MER
