Background To gain insight into the role of plantar intrinsic foot muscles in fall-related gait parameters in older adults, it is fundamental to assess foot muscles separately. Ultrasonography is considered a promising instrument to quantify the strength capacity of individual muscles by assessing their …

The simultaneous analysis of a broad range of polar ionogenic metabolites using capillary electrophoresis-mass spectrometry (CE-MS) can be challenging, as two different analytical methods are often required, that is, one for cations and one for anions. Even though CE-MS has shown to be an effective method …

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 …

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 …

Saybolt is a petrochemical company that invest in different types of oils and fuels. Saybolt Vlaardingen has purchased a new Perkin Elmer Optima 8300 ICP-OES (Inductively coupled plasma optical-emission spectrometry) that must be validated. The ICP-OES is used to analyze metals in petroleum products. This …

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 deze studie is de betrouwbaarheid van een nieuwe normalisatie methode voor oppervlakte EMG amplitude onderzocht. Deze nieuwe methode is nodig omdat bestaande methodes niet geschikt zijn voor patiënten met Osteo Artrose (OA). Resultaten van deze studie leveren een innovatieve bijdrage aan de revalidatie …

The customers of Inspectorate ship gasoline to Asia. Due to the limitations of the ships and costs of the journey it is preferred to concentrate the gasoline. The concentrated gasoline can be blended with other “cheaper” forms of gasoline to make the required gasoline. Because of the concentrated form …

Previous researches have shown that there is a link between surface quality and equine performance and therewith potential injury risk. Therefore the question about optimal surface rises. But still comparable values and standardized measurement methods are missing. Therefore the aim of this research …

Achtergrond Facioscapulohumerale dystrofie (FSHD) is een spierziekte waarbij spiervervetting voorafgegaan wordt door een ontsteking. Aangenomen wordt dat vetinfiltratie voorkomen kan worden door de voorafgaande ontsteking te behandelen. Op dit moment wordt gezocht naar een behandeling voor deze ziekte. …
