1. Glacial erosion zonation : perspectives on topography, landforms, processes and time
Sammanfattning : .... LÄS MER
2. Internal oxygen transport to below-ground parts: importance for emergent macrophytes
Sammanfattning : This thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. LÄS MER
3. Late Quaternary Biostratigraphy of Sediments of the Southeastern Baltic Sea
Sammanfattning : This thesis presents Late Quaternary biostratigraphy in the SE Baltic Sea, based on palynological data from fifteen sediment cores. An objective subdivision of the cores has been achieved by numerical zonation. Ordination has revealed a succession of pollen spectra that can be used for biostratigraphic correlation across the region. LÄS MER
4. Water as a trace component in mantle pyroxene: Quantifying diffusion, storage capacity and variation with geological environment
Sammanfattning : In this study, distribution and diffusion of water in pyroxene are examined in an effort to explain the water content variation observed in natural pyroxene. Water is a common trace component in many nominally anhydrous minerals (NAMs) from the Earth's crust and mantle and greatly impacts their physical properties. LÄS MER
5. Proteomic and Functional Analysis of In Vitro Systems for Studies of Drug Disposition in the Human Small Intestine and Liver
Sammanfattning : To reach the bloodstream, an orally administered drug must be absorbed through the small intestine and avoid extensive clearance in the liver. Estimating these parameters in vitro is therefore important in drug discovery and development. LÄS MER
