1. Upflow anaerobic sludge blanket reactor modelling
University dissertation from Stockholm : US-ABAbstract : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

2. Indoor emissions and fate of flame retardants A modelling approach
University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm UniversityAbstract : A significant number of consumer goods and building materials act as emission sources of flame retardants (FRs) in the indoor environment. As a result, FRs have become ubiquitous indoors raising concerns about human exposure and possible health implications. READ MORE

3. Study of precipitation in martensitic Fe-C-Cr alloys during tempering Experiments and modelling
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. READ MORE

4. Delamination in APS applied thermal barrier coatings : life modelling
University dissertation from Linköping : Linköpings universitetAbstract : Thermal barrier coatings, TBCs, are used in gas turbines as a thermal shield resulting in lower temperature in coated components. The decrease of temperature allows higher gas temperatures in the turbine, which increase the efficiency. READ MORE

5. Environmental Modelling Learning from Uncertainty
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that understanding and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE
