Perfluoro alkyl substances (PFAS) are substances in which contain multiple fluorine atoms. The fluorine atoms are bound to, often, long carbon chains. PFAS are able to repel dirt and water, due to the large amount of fluorine atoms in the molecules. PFAS are also chemically and thermally stable. Many …

Background: This paper describes the Co-Care-KIT, a reflective toolkit designed to provide insights into the diverse experiences of home-based informal caregivers during the delivery of care to a relative or loved one. Objective: The aim of this study was to evaluate the toolkit, including a custom-designed …

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 species blonde ray (Raja brachyura) and thornback ray (Raja clavata) have been selected for the 2.1 InnoRays project, to get more insight about the status of these stocks in the Greater North Sea. Unstained and stained age determination methods were tested and LFQ data analysis are conducted for …

Background: Magnetic resonance imaging (MRI) is being used extensively in the search for pathoanatomical factors contributing to low back pain (LBP) such as Modic changes (MC). However, it remains unclear whether clinical findings can identify patients with MC. The purpose of this explorative study was …

Modern safety thinking and models focus more on systemic factors rather than simple cause-effect attributions of unfavourable events on the behaviour of individual system actors. This study concludes previous research during which we had traced practices of new safety thinking practices (NSTPs) in aviation …

Using the reversed phase high performance liquid chromatography with diode-array and massspectrometric (in ESI mode) detection, a composition of Catharanthus roseum petals was established. After the acid hydrolysis, all five anthocyanidins were found to be different comparing to the ordinary anthocyanidins …

Logopedisten en klinisch linguïsten onderzoeken de taalontwikkeling van jonge kinderen met een vermoedelijke of al vastgestelde taalontwikkelingsstoornis. Ze onderzoeken ook de taalvaardigheid van personen met afasie. Naast gestandaardiseerde tests worden samples spontane taal geanalyseerd. …

Voor het meten van elektrochemische processen van micro- tot nanoschaal wordt een techniek ontwikkeld die elektrochemische impedantiemetingen met een AFM naald mogelijk maken. Hierbij bevindt zich actief materiaal op een AFM naald en worden er metingen verricht in elektrolyt. Tijdens dit onderzoek …

This study, titled Sweetening the Deal, considers policy interventions to reduce sugar consumption. The study addresses the research question: To what extent does public opinion in the Netherlands and in the United Kingdom either correspond or contrast to policy approaches being taken by their governments …
