6. Nutrient recovery from waste streams through struvite formation
Abstract : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. READ MORE

7. Agricultural nutrient budgets in Europe: data, methods, and indicators
Abstract : Agricultural production systems feed humanity but also cause a range of adverse environmental effects, including climate change, loss of biodiversity, and pollution of air and water. A main cause of these effects is the emissions of nitrogen (N) and phosphorus (P) that occur as a side effect of nutrient cycling in agriculture. READ MORE

8. Silicon cycling in the Baltic Sea : Trends and budget of dissolved silica
Abstract : The dissolved silicon (DSi) has a crucial role for growth of a large group of primary producers – diatoms and, hence, impact on functioning of the aquatic food web. This thesis contributes to an increased understanding of the modifications of the DSi cycling in the Baltic Sea. READ MORE

9. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish
Abstract : The aim of this thesis was to identify general structuring mechanisms in benthic food webs within the framework of ecological stoichiometry theory. Ecological stoichiometry is defined as the balance of multiple chemical substances in ecological interactions and explicitly considers the combined dynamics of key elements such as carbon (C), nitrogen (N) and phosphorus (P).

10. Unlocking the Role Of Orphan Solute Carrier SLC38A10 In Brain Metabolism : The SLC38A10 transporter in nutrient and metabolic regulation
Abstract : Membrane transporters are the primary gatekeepers of cells and regulate the transport of nutrients, metabolites, ions, water, and neurotransmitters into and across the human cells. The solute carrier transporters (SLCs) are the most prominent transporters, comprising 430 members divided into 65 subfamilies. READ MORE
