6. Influence of Composition and Pore Geometry on Immiscible Fluid Flow through Greensands: Development of Neutron Transmission Methods and Image Analysis
Sammanfattning : The effect of the mineralogical composition and pore geometry of sediments on the distribution as well as the flow of immiscible fluids are of importance when evaluating petroleum reservoirs. Greensand containing the clay mineral glauconite is a complex reservoir rock type. LÄS MER
7. Nuclear pore membrane glycoprotein 210 as a new marker for epithelial cells
Sammanfattning : Epithelial cell polarisation is a prerequisite for the branching morphogenesis in several organs. Differential screening techniques were used to identify genes, which are upregulated during induction of epithelium in early kidney development. LÄS MER
8. Ischemic and Hypoglycemic Brain Damage, Involvement of the Mitochondrial Permeability Transition Pore
Sammanfattning : Brain damage from ischemia-reperfusion and hypoglycemia are major causes of morbidity and mortality. Therapeutic strategies include hypothermia, glutamate-receptor blockade, immunosuppression and lately treatment aiming at preserving mitochondrial integrity and function. LÄS MER
9. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts
Sammanfattning : Hydrodemetallization (HDM) is an indispensable step in industrial catalytic hydroprocessing of residual oils. To develop improved HDM catalysts and reactors, a detailed knowledge of the reaction mechanisms and kinetics, and a good understanding of the mechanisms and process of the catalyst decaying are very important.

10. Mesostructured particulate silica materials with tunable pore size : Synthesis, characterization and applications
Sammanfattning : Colloidal assemblies of surfactants and polymers in aqueous solutions have been used by human mankind for hundreds of years and they are of great importance in many of our technological processes, such as fabrication of soap and papermaking. Less than two decades ago the idea of using colloidal assemblies as templates of inorganic materials was borne. LÄS MER
