The European common cuttlefish (Sepia officinalis) makes use of undulatory locomotion through its lateral fins. This type of locomotion shows good potential for application for underwater vehicle thrust because it gives the user advantages like maneuverability, stable station keeping, and energy efficiency. …

XblocPlus is a single layer armour unit developed by BAM Infra Consult. The XblocPlus is the successor of the Xbloc and one of the main changes is that it is placed in a uniform pattern. Most of its hydraulic stability comes from the interlocking that the XblocPlus does. XblocPlus consists entirely …

Waterschap Scheldestromen is carrying out a particularly innovative project named Multiflexmeter (MFM), of which the objective is to look for ways to measure the soil resistance . This means some properties and characteristics of water needs to be researched on, such as the salinity and the corresponding …

Out of the urgent need to monitor the status of soil salinization, the Zeeland government and Waterschap Scheldestromen established a salinity monitoring project called salt watcher. This thesis presents a research on the design of an automatic switch system, which is one of the 3 sub-projects of the …

The cryptophyte Rhodomonas salina is widely used in aquaculture due to its high nutritional profile. This study aims to investigate the effect of salinity and pH on the growth, phycoerythrin concentrations, and concentrations of non-volatile umami taste active compounds of R. salina, using a design of …

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 …

This study aimed to get more insight into the spatial distribution pattern of the macrobenthos at the Vlakte van de Raan in relation to environmental gradients (median grain size, salinity and bathymetry). 82 samples were collected in November 2016 with a Van Veen grab using the research vessel the ‘RV …

Fish have the natural behaviour to move across various aquatic ecosystems and for some species this is of vital importance. Migration is often a seasonal phenomenon which occurs in order to move between habitats, such as winter refuges-, foraging- and spawning or nursery habitats, also escaping unfavourable …

Laboratory research was done on flat glass substrates to study the effect that brine salinity has on adhesion mechanisms between oil and clay particles. This is done by evaporating a small clay suspension droplet (6 ul) on a glass slide that leaves a thin layer of clay upon which oil can be attached. …
