1. Low consistency refining of mechanical pulp : process conditions and energy efficiency
Abstract : The thesis is focussed on low consistency (LC) refining of mechanical pulp. Theresearch included evaluations of energy efficiency, development of pulpproperties, the influence of fibre concentration on LC refining and effects of rotorposition in a two-zoned LC refiner. READ MORE

2. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems
Abstract : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. READ MORE

3. Mine production index: Development and application
Abstract : Assuring production forms a crucial part of mining business profitability. Factors related to various mine operations, activities and business processes can threaten required/planned mine production. To address problems and ensure production level in mining, it is necessary to implement a mine production assurance program (MPA). READ MORE

4. Nanofluidic Scattering Microscopy for Single Particle Catalysis
Abstract : Heterogeneous catalysis concerns material formulations – catalysts – that can assist a chemical reaction by improving its rate or selectivity, by lowering activation barriers and altering the energy landscape. The core of catalysts are often tiny metal particles that provide a large reaction surface at a small volume, as well as low coordination sites whose type and abundance depends on particle size and shape.

5. Price measurement and index construction : some contributions to theory and application
Abstract : Four different problems are treated, all concerned with problems arising when compiling price indexes in official statistics. One deals with the computation of so called elementary aggregates, low level indexes for single products, when proper weights for the observations are not available. READ MORE
