1. Wet Low-Intensity Magnetic Separation: Measurement methods and Modelling
Sammanfattning : In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. LÄS MER
2. Cost-Benefit Analysis of Separation Distances - a utility-based approach to risk management decision-making
Sammanfattning : Decision-making in risk management reflects a normative choice of approach. This dissertation is concerned with the possibility of putting the decision in focus by employing an optimum decision criterion within a utility-based approach. LÄS MER
3. Turbulent Boundary Layer Separation and Control
Sammanfattning : Boundary layer separation is an unwanted phenomenon in most technical applications, as for instance on airplane wings, ground vehicles and in internal flow systems. If separation occurs, it causes loss of lift, higher drag and energy losses. It is thus essential to develop methods to eliminate or delay separation. LÄS MER
4. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes
Sammanfattning : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. LÄS MER
5. Dynamics of Excitation Transfer and Charge Separation in Polymeric Semiconductors
Sammanfattning : Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. LÄS MER
