1. Mechanistic Modelling of Drug Dissolution and Matrix Formulations: Rotating Disc Dissolution, Dissolution in a Stagnant Medium, Swelling and Dissolving Matrix Systems
Abstract : Popular Abstract in Swedish Under årens lopp har människan gjort stora landvinningar inom läkemedelsforskning, vilket har lett fram till avancerade läkemedel som idag tas för givna. Avancerade läkemedel sätter dock höga krav på tillverkarna av läkemedel, vilket har lett till att framtagandet av nya läkemedel är en ganska komplicerad process. READ MORE

2. Improved energy efficiency in double disc chip refining
Abstract : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. READ MORE

3. Rearrangement of gas in disc galaxies
Abstract : Active galactic nuclei and bursts of star formation are two distinct phenomena that amply change their host environments. They are present in a significant number of galaxies at all redshifts. In this thesis, we aim toward a better understanding of the physical processes that allow for the formation and maintenance of these two phenomena. READ MORE

4. An experimental study of fiber suspensions between counter-rotating discs
Abstract : The behavior of fibers suspended in a flow between two counter-rotating discs has been studied experimentally. This is inspired by the refining process in the papermaking process where cellulose fibers are ground between discs in order to change performance in the papermaking process and/or qualities of the final paper product.

5. Volatility and number measurement of diesel engine exhaust particles
Abstract : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. READ MORE
