1. Bayesian Phylogenetics and the Evolution of Gall Wasps
Sammanfattning : This thesis concerns the phylogenetic relationships and the evolution of the gall-inducing wasps belonging to the family Cynipidae. Several previous studies have used morphological data to reconstruct the evolution of the family. LÄS MER
2. Structural and Antibacterial Properties of Silver(I) Compounds with N-donor Ligands: A Challenge for Medical Applications
Sammanfattning : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. LÄS MER
3. Distance education and the training of primary school teachers in Tanzania
Sammanfattning : Tanzania has been using distance education to train its teachers for twenty years. Thefirst programme, which began in 1976 and ended in 1984, was highly innovative inits approach. It provided both professional and up-grading studies within the primaryschools to try and meet the demand for universal primary education. LÄS MER
4. Monitoring lithospheric motions by Satellite geodesy
Sammanfattning : Understanding of global and local Earth’s dynamic processes is of great importance to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). LÄS MER
5. Optical Modeling and Characterization of Layers and Multilayer Structures : Organic Optoelectronic Devices and Spectroscopic Ellipsometry
Sammanfattning : This dissertation is on the subject of modeling and characterization of layers and multilayer structures with respect to their optical properties and characteristics. A number of different systems have been investigated; among them multilayer structures in the form of organic optoelectronic devices, anisotropic layers of conjugated polymers as well as inhomogeneous layers of porous silicon and oxidized silver.
