1. "Under pressure" : interaction between pharmaceuticals and river bacteria
Abstract : Pharmaceuticals are often entering the environment without being completely decomposed. Once released in the environment they continue to carry on their main function but instead targeting the inhabitants of the aquatic ecosystem. Our interest was drawn towards the bacteria, that are often present in the environment in the form of biofilms. READ MORE

5. Theoretical Investigation into Longitudinal Dispersion in Natural Rivers — A Scaling Dispersion Model
Abstract : Using a broad variety of scientific methods this dissertation systematically investigates the fundamental mechanisms underlying the dispersion processes in natural rivers and their mathematical descriptions in a geometrical framework. Emphasis is on the geometrical variations and irregularities of a natural river and their scales. READ MORE
