Early links in the food web are crucial to sustain higher levels in the food web. Molecules of high importance, for example unsaturated fatty acids, play a key role in aquatic ecosystems. Unsaturated fatty acids are produced by primary producers for instance phytoplankton. Almost all organisms need to …

In order to increase feed quality, additive has been used to increase silage storage stability. During feeding time, the silage is exposed to oxygen and a degrading process starts decreasing dry matter and increasing temperature. This rise in temperature makes the silage less appetising to cows, few …

Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …

In this study, various extraction methods were compared based on their ability to extract both free amino acids, and free 5’-monophosphate nucleotides from the seaweed Saccharina latissima. Based on the results, extraction at room temperature with Milli-Q over 24 hours was chosen as the method of choice, …

In this report, the further optimization of the PMI method is investigated and the possibility to act as an alternative method for the Chemical Oxygen Demand (COD) in wastewater is discussed. In this study the oxidation efficiency of the PMI method is improved by optimizing the oxidation time, concentration …

Introduction: Subfertility is a growing problem in The Netherlands. Assisted reproductive techniques (ART) are applied to aid subfertile couples conceiving. The EmbryoScope is a novel incubator, used in ART, to cultivate embryos under optimal conditions. The EmbryoScope provides time lapse images, which …

Result of the study on the exposure of imidacloprid on Lymnaea stagnails, have led to this study. The results indicate that imidacloprid might be metabolized to other components. Therefore the aim of the study was two folded: 1. To develop a method for the quantification of imidacloprid and its metabolites. …

Genetic assays are very useful tools for clinical diagnostics and therapeutics. This thesis addresses the development of electrochemical microRNA genosensor, envisioned to be used as a clinical diagnostic tool. Dysregulation of numerous microRNAs have been reported to be closely associated to diseases. …

Tomato (Lycopersicon esculentum) is one of the important vegetables in Rwandese diet, since it is rich in health valued food components such as carotenoids (Lycopene), ascorbic acid (Vitamin C), vitamin E, folate and dietary fibers. The post harvest loss in tomatoes has been estimated to be about 20-30% …
