1. Microplastics in the aquatic environment: Insights into biological fate and effects in fish
Sammanfattning : According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. It has been predicted that up to 12 million tons of plastic waste reach the aquatic environment annually. LÄS MER
2. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization
Sammanfattning : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. LÄS MER
3. Computational chemistry studies of UV induced processes in human skin
Sammanfattning : This thesis presents and uses the techniques of computational chemistry to explore two different processes induced in human skin by ultraviolet light. The first is the transformation of urocanic acid into a immunosuppressing agent, and the other is the enzymatic action of the 8-oxoguanine glycosylase enzyme. LÄS MER
4. On some positive effects of swirling flow for the continuous cast mould billets
Sammanfattning : Continuous caster moulds are the last and most important stage in the steelmaking process, where inclusions can either be generated or removed. With increasing casting speed using conventional immersion nozzles critical problems, such as unstable bulk mould flow have been noticed. LÄS MER
5. Developmental co-ordination disorder in pre-school children : Effects of motor skill intervention, parents' descriptions, and short-term follow-up of motor status
Sammanfattning : This investigation was undertaken to examine effects of motor skill intervention in children with motor difficulties consistent with developmental co-ordination disorder (DCD) diagnosed in child health care before school entrance, to analyse the parents' descriptions of their children, and to follow up the children's motor status in a short-term perspective. Thirteen studies on the effects of motor skill intervention were submitted to a meta-analysis (Study I). LÄS MER
