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 …

This research is to investigate to what extend the NIOSH-7605 and ISO-16740 methods can be used to determine insoluble hexavalent chromium in air. The methods were tested and optimized on the extraction and sample preparation steps. After optimization the methods were validation on limit of detection …

Many people on Earth are hungry or do not have a reliable source of drinking water. Drought-tolerantcrops do not need much water to grow and therefor usable in regions where water is an issue. Cropbreeders are working on crops that are more drought-tolerant and grow faster. Corp …

Under the premise that language learning is bidirectional in nature, this study aimed to investigate syntactic coordination within teacher-student interactions by using cross-recurrence quantification analysis (CRQA). Seven teachers’ and a group of their students’ interactions were repeatedly measured …

The amino acid profile obtained from a fingerprint may provide valuable information on its donor. Unfortunately, the collection of chemicals from the fingerprint is often destructive to the fingerprint ridge detail. Herein we detail the use of cross-linkable solutions of dextran-methacrylate to form …

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 …

It can be concluded that the HBM4EU serum sample preparation method is suitable for Effect-Directed Analysis. The method allows a recovery of all bioactive compounds of interest from serum in the EDA products, with little loss of compounds: bioassay spectra and chromatograms. Nevertheless, the HBM4EU …

A method for directly analysing the nickel content of organic samples by flame atomic absorption is validated. This method is developed to bypass the conventional preparation step for aqueous atomic absorption, which is microwave digestion. The working range of the method is 0 – 30 ppm. The limits of …

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 …

Verslag van een presentatie. In onderzoeken naar de prioriteiten van HR-professionals staan analytics dan ook steevast onderaan het prioriteitenlijstje. Echter, nu elke dag meer data beschikbaar komen en alles is te meten, is dit niet langer een houdbaar standpunt. HR-professionals zullen op zijn minst …
