1. Gefiolierte blüte kunst : Eine kognitionslinguistisch orientierte Untersuchung zur Metaphorik in Frauenlobs Marienleich
Sammanfattning : Heinrich of Meißen, also known as Frauenlob († 1318), is a central figure in Middle High German literature. As is evident from its early reception, his work was highly admired in the middle ages. In research literature, however, his ‘obscure’ poetry initially was faced with a lack of understanding. LÄS MER
2. Direct Catalytic Nucleophilic Substitution of Non-Derivatized Alcohols
Sammanfattning : This thesis focuses on the development of methods for the activation of the hydroxyl group in non-derivatized alcohols in substitution reactions. The thesis is divided into two parts, describing three different catalytic systems. LÄS MER
3. Welfare Relationships : Voluntary organisations and local authorities supporting relatives of older people in Sweden
Sammanfattning : Sweden is often described as a country with a strong welfare state and little voluntary work. This is as would be expected according to substitution theory, in which extensive welfare systems are assumed to crowd out voluntary activity and thereby limit the potential for voluntary work – there is an inverse relationship between voluntary and statutory activity.

4. Density Functional Theory Applied to Materials for Spintronics
Sammanfattning : The properties of dilute magnetic semiconductors have been studied by combined ab initio, Monte Carlo, and experimental techniques. This class of materials could be very important for future spintronic devices, that offer enriched functionality by making use of both the spin and the charge of the electrons. LÄS MER
5. Quantum Chemical Studies of Chemotherapeutic Drug Cisplatin : Activation and Binding to DNA
Sammanfattning : The serendipitous discovery of the potent cytotoxic properties of cisplatin brought about a revolution in the treatment of certain types of cancer, but almost fifty years later, there still remain unknown areas in the chemistry of cisplatin. There are questions regarding which form of the drug reaches its DNA target, or why certain DNA sequences are more preferred than others for reaction with cisplatin. LÄS MER
