This thesis project has been carried out at VHL (Van Hall Larenstein University of Applied Sciences) and consists of three different parts; the first part is an experiment in which during 20 days of cultivation the optimum nitrate concentration for protein production in Ulva lactuca is sought. U. lactuca …

Sustainable Urban Drainages Systems (SuDS) are designed to collect, store and infiltrate large amount of surface runoff water during heavy rainfall. Surface runoff water is known to transport pollutants such as particle bound heavy metals. Therefore, a build-up of pollutants in the top-soil, of the commonly …

During this research project the influence of selenium enriched growing environment on the phenolic composition on several Allium species is studied. Besides this, the influence on morphological properties is also monitored. Folin-Ciocalteu method is used to determine the total phenolic content and High …

This graduation research thesis is written following the assignment conducted at the Own Greenscompany to write a protocol for the use of increased concentrations of CO2 for the production oftheir crops. As a result of writing that protocol, it was researched what these effects of increased CO2concentrations …

Climate change accentuates heat waves in The Netherlands. This, in combination with high nutrient concentrations in Dutch surface waters, is intensifying the proliferation of toxic blue-green algae (cyanobacteria), a threat for the health of the population and ecosystems. Lakes are resources for recreational …

Lasiocarpine and riddelliine are pyrrolizidine alkaloids (PAs) known to cause liver toxicity. The aim of this study was to predict the inter-species and inter-ethnic human differences in acute liver toxicity of lasiocarpine and riddelliine using physiologically based kinetic (PBK) modelling based reverse …

Background & aims Plasma citrulline concentration is considered to be a marker for enterocyte metabolic mass and to reflect its reduction as may occur during intestinal dysfunction. Strenuous exercise can act as a stressor to induce small intestinal injury. Our previous studies suggest that this comprises …

English -- The impact of residualisation on social work has so far hardly been explored. Based on existing literature and recently started empirical research in Amsterdam we analyze several consequences. Residualisation refers to the process whereby urban social housing is strictly allocated to the lowest …

Introduction In the harbor of Zierikzee there is a strong tidal influence. The difference between the water levels during high and low tide lies around the three meters. The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …
