11. Development of Protein-Functionalized Magnetic Iron Oxide Nanoparticles: Potential Application in Water Treatment
Sammanfattning : The treatment of water to make it safe for human consumption is a problem of immense concern, both in developing and developed countries. However, the production of clean water with chemicals as coagulants has several drawbacks associated with cost, health risks and complexity in sludge management. LÄS MER
12. Spring dynamics in shallow lakes: the role of plankton, fish and macrophytes in a changing climate
Sammanfattning : Shallow lakes such as Lake Krankesjön are characterized by their extended littoral zones, usually covered by submersed and emergent vegetation. In paper 1, I investigated the relationship between turbidity and macrophyte growth (Chara spp. LÄS MER
13. Coagulation process characteristics and pollutant removal from urban runoff
Sammanfattning : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies. The treatment function of SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles. LÄS MER
14. Submerged macrophytes in shallow eutrophic lakes - regulating factors and ecosystem effects
Sammanfattning : In this thesis I have studied factors that regulate submerged macrophyte abundance, morphology and distribution in shallow eutrophic lakes, and how submerged macrophytes may affect the ecosystem. Light attenuation through the water column (turbidity and water depth) is probably not the most important factor regulating the distribution of submerged vegetation in macrophyte dominated shallow eutrophic lakes, e.

15. Foraging behaviour in piscivorous fish: mechanisms and patterns
Sammanfattning : Mechanistic understanding of piscivore foraging at the individual level is important in order to understand and make predictions of piscivore effects at population and community levels. To understand the mechanisms affecting selection and consumption rates each step in the foraging cycle (search, encounter, active choice, attack, capture, ingestion, digestion) should be studied.
