11. Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems
Sammanfattning : In this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. LÄS MER
12. Recycling kraft pulp mill solid residues to the forest : treatment and leaching characteristics
Sammanfattning : .... LÄS MER
13. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process
Sammanfattning : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. LÄS MER
14. Particle emissions from wood pellet combustion
Sammanfattning : Combustion of solid biomass under fixed bed conditions is a common technique to generate heat and power in both small and large scale grate furnaces (domestic boilers, stoves, district heating plants). Unfortunately, combustion of biomass will generate particle emissions containing both large fly ash particles and fine particles that consist of fly ash and soot. LÄS MER
15. Implication of pellet quality on combustion performance
Sammanfattning : Quality aspects of wood pellets and their use have been of utmost importance since the development of the pellet market in the early 1980s. Research and hard-earned knowledge have resulted in advancements in the field, but there are still uncertainties in the pellet industry about how different quality aspects affect combustion performance.
