11. The relation between microstructure and mechanical properties of cobalt- and nickel-rich Co-Ti-C and Ni-Ti-C alloys
Sammanfattning : Age-hardening processes up to l000°c which might be important in the binder phase of the Co-Ti-C and Ni-Ti-Chard metal systems have been studied mainly by high voltage electron microscopy, (HVEM), optical microscopy (OM) and scanning electron microscopy (SEM) as well as by micro-and macrohardness measurements and tensile testing at room and elevated temperatures (500°-800°). In addition,the allotropic transformation of cobalt has been followed by X-ray diffraction in order to permit a more complete interpretation of the changes in microstructure reflected in the mechanical testing.

12. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests
Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER
13. The value of experimental data and modelling for exploration of hydrological functioning: The case of a till hillslope
Sammanfattning : Successfully modeling one system response (e.g. hydrograph or solute transport) sometimes gives the false sense of well-characterizing the modeled system. This is partly because of the well-known equifinality issue; during the calibration process multiple parameter combinations can produce similarly good results. LÄS MER
14. Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic
Sammanfattning : It has been shown that the present interglacial has been climatically dynamic with both rapid and severe climatic fluctuations. The spatial and temporal differences of these changes are however not fully resolved. The aim of this thesis is to present a detail high resolution record of past climate changes from the central South Atlantic. LÄS MER
15. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
Sammanfattning : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER
