Awareness of climate change and stricter emission regulations have accelerated the search for sustainable energy solutions. A central goal is carbon-neutral energy use, minimizing greenhouse gas emissions while ensuring reliable energy supply. In applications with limited grid access—such as festivals, …

This study explores the effect of precipitation, evaporation, animal burrowing and the changing climate on the permeability of the clay cover layer on a dike. It also showcases the possibility of utilizing finite difference flow models, such as MODFLOW, for the simulation of various environmental impacts …

Per-fluoroalkyl and polyfluoroalkyl substances (PFASs) are persistent organic pollutants and do not degrade in the environment. They contain a carbon-fluorine bond, and these are called organic fluorides. A group of PFASs, which can be extracted from soil samples and be analysed, are called extractable …

In this research several methods were developed and validated using the Supermini 200 wavelength dispersive X-ray fluorescence spectrometer. A multielement was calibrated containing 26 elements and corrected for interference according to the de Jongh algorithm. The limits of detection and quantification …

Voor Leiderdorp Instruments, een ingenieurs bedrijf gespecialiseerd in productie van meetinstrumenten voor de bouw, is er een kalibratiesysteem ontwikkeld om het productie proces te versnellen en de werknemers meer mogelijkheden te geven in het testen van de producten. Het te testen apparaat is een druk …

The use of TriAx geogrids to stabilise the granular base layer of asphalt paved roads, is ever increasing. However, the effect a stabilising geogrid has on the entire pavement structure is still derived from a foundation reduction factor, instead of being calculated directly. Practical experience showed …

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 …

The demand of renewable energy in the European Union is increasing significantly in order to reduce CO2 emissions. Efforts are being made for further development of biomethane and hydrogen to use it as a clean and sustainable fuel for vehicles. However, biomethane and hydrogen contains impurities that …

In the Province of Zeeland, ragworms (Alitta virens) are farmed on large scale in open rectangular (flow through systems) ponds. In April these ponds are stocked with ragworm larvae from a hatchery. The juveniles bury themselves in the sediment layer in the pond and are fed with feed pellets. Dependent …

Kinematical joint analysis during road cycling is a new trend. Reviewing the methods for 2D and 3D lower limb kinematical research, the sensor to segment alignment appeared to be the most challenging part due to unknown orientation with respect to the anatomical joints. A methodology that is suitable …
