21. Mathematical modeling and numerical tools for simulation and design of light scattering in paper and print
Sammanfattning : This work starts with a real industrial problem - the perceived need for a moredetailed and more accurate model for light scattering in paper and print than theKubelka‐Munk model of today. A careful analysis transfers this problem into aphysical description of the phenomena involved. LÄS MER
22. Theoretical Actinide Chemistry – Methods and Models
Sammanfattning : The chemistry of actinides in aqueous solution is important, and it is essential to build adequate conceptual models and develop methods applicable for actinide systems. The complex electronic structure makes benchmarking necessary. LÄS MER
23. Nuclear magnetic resonance studies on bentonite in complex mixed systems
Sammanfattning : In this work 23Na MAS NMR was validated as a successful quantitative method for studies of exchanging sodium in bentonites useful, in particular, for studies of ion-exchange kinetics. Na-enriched bentonites equilibrated in a re-circulated process water at iron-oxide pelletizing plants may acquire properties of Ca-bentonites after already 20 minutes of the equilibration time, since >50 % of sodium ions will be exchanged by calcium ions during first minutes of bentonite placed in contact with the process water.

24. Transition Metal Mediated Transformations of Carboranes
Sammanfattning : This thesis describes the use of copper and palladium to mediate transformations of carboranes, especially p-carborane.1-(1-p-carboranyl)-N-methyl-N-(2-butyl)-3-isoquinolinecarboxamide, a carborane containing analogue of the peripheral benzodiazepine receptor (PBR) ligand PK11195, has been synthesised.

25. NHBD Lung Transplantation
Sammanfattning : The waiting list for lung transplantations world-wide is steadily growing. So, the use of lungs from non-heart-beating donors (NHBD) needs to be addressed. Hence, the aim of this thesis was to evaluate, in realistic animal models, the new donor organ concept: NHBD transplantation. LÄS MER
