Active participation in physical activity (PA) is beneficial for teenagers’ physical and mental development [1]. Moreover, it can also prevent childhood obesity and cardiovascular diseases [2]. However, extensive studies have shown that most adolescents (12-15 years) tend to drop out from regular PA …

In light of recent developments of the onboard ballast water treatment, WMR has developed a new protocol for the assessment of ecotoxicological effects and aims to use it as a standardised test. This study looks into the validation of this short-chronic ELS fish toxicity test, by use of the embryonic …

The demand for the transport of goods within the city is rising and with that the number of vans driving around. This has adverse effects on air quality, noise, safety and liveability in the city. LEFVs (Light Electric Freight Vehicles) offer a potential solution for this. There is already a lot of enthusiasm …

Research demonstrated a large variety regarding effects of light (e.g. health, performance, or comfort effects). Since human health is related to each individual separately, the lighting conditions around these individuals should be analysed individually as well. This paper provides, based on a literature …

Background: The emphasis on impact factors and the quantity of publications intensifies competition between researchers. This competition was traditionally considered an incentive to produce high-quality work, but there are unwanted side-effects of this competition like publication pressure. To measure …

In the four studies comprising this dissertation, we aim to shed more light on the role of implementation quality of FLPs. In the first study, we reviewed the literature on implementation quality of FLPs, to gain insight into how implementation has been assessed in studies so far, what previous studies …

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 …

To increase the yield and quality of aquaculture feed, the effects of N and P concentrations on biomass productivity and cell composition were examined in the marine diatom Skeletonema costatum. Batch-cultured microalgae in Walne’s medium with 3.5 ± 0.5 mmol L-1 N-NO3- and 0.30 ± 0.05 mmol L-1 P-PO43- …

Background: The objective of this study was to derive evidence-based physical activity guidelines for the general Dutch population. Methods: Two systematic reviews were conducted of English language meta-analyses in PubMed summarizing separately randomized controlled trials and prospective cohort studies …
