Perfluoro alkyl substances (PFAS) are substances in which contain multiple fluorine atoms. The fluorine atoms are bound to, often, long carbon chains. PFAS are able to repel dirt and water, due to the large amount of fluorine atoms in the molecules. PFAS are also chemically and thermally stable. Many …

Salt marsh stability from 10 different salt marshes was studied in the Dutch Wadden Sea region and the Scheldt Estuary during October and November 2018. This report elaborates how salt marsh stability is influenced by bioturbation of Orchestia sp., grazing of large herbivores and different soil and plant …

This review of meta-analyses of outcome studies of adults receiving Computer-Based Health Education (CBHE) has two goals. The first is to provide an overview of the efficacy of CBHE interventions, and the second is to identify moderators of these effects. A systematic literature search resulted in 15 …

Volgens de Verenigde Naties is verwoestijning een van de grootste bedreigingen van onze planeet. (Knudsen, 2015) Verwoestijning is vaak een zichzelf versnellend proces. De bodem kan plotseling ongeschikt raken voor verschillende planten door verzilting. Het klimaat verandert ook doordat de begroeiing …

From the thesis: SUMMARY Raspberry-like particles were made with spherical positively charged seed particles and spherical negatively charged smaller particles. The attraction from the small particles onto the surface of the seed particles is a heterocoagulation technique. It has been proven that it …

Intertidal areas in the Netherlands suffer from divers pressures in the delta. The Western Scheldt has an open connection to the sea. This system is in use for the Port of Antwerp, for which dredging is required. Therefore, Rijkswaterstaat has to compensate natural areas, among which intertidal areas. Area …

Mild steel is the main material of alloys in use. Approximately 20% of corrosion damage of metals is induced by bio corrosion. The aim of this research was to study the corrosion performance of mild steel and stainless steel when immersed in natural seawater. In order to verify the effect of the microorganisms …
