Electrification of residential areas is increasingly common. Major areas of development include rooftop solar panels, electric vehicles and heat pumps. However, existing grid components may have insufficient network capacity to accommodate the resulting electricity flows. Battery energy storage (BES) …

The built environment requires energy-flexible buildings to reduce energy peak loads and to maximize the use of (decentralized) renewable energy sources. The challenge is to arrive at smart control strategies that respond to the increasing variations in both the energy demand as well as the variable …

Already for some decades lateral flow assays (LFAs) are ‘common use’ devices in our daily life. Also, for forensic use LFAs are developed, such as for the analysis of illicit drugs and DNA, but also for the detection of explosives and body fluid identification. Despite their advantages, including ease-of-use, …

This paper presents challenges in city logistics for circular supply chains of e-e-waste. Efficient e-waste management is one of the strategies to save materials, critical minerals, and precious metals. E-waste collection and recycling have gained attention recently due to lower collection and recycling …

Dit onderzoek, is uitgevoerd namens Heijmans B.V. en het SoSEAL innovatie team. Dit onderzoek is uitgevoerd om de ontwikkeling van de innovatie SoSEAL als pipingmaatregel verder te brengen. Dit is gedaan binnen het dijkversterkingsproject Sterke Lekdijk, deeltraject Wijk bij Duurstede - Amerongen (WAM). …

Clonal haematopoiesis of intermediate potential (CHIP) driven by somatic mutations in DNMT3A and TET2 has been recently recognized as a new risk factor for cardiovascular diseases (CVD). The haematopoietic clones with mutations in these genes are frequently found in myeloid malignancies and according …

The COVID–19 pandemic led to local oxygen shortages worldwide. To gain a better understanding of oxygen consumption with different respiratory supportive therapies, we conducted an international multicenter observational study to determine the precise amount of oxygen consumption with high-flow nasal …

The main objectives of this review were to: (1) review different methods/techniques to assess gaseous N-losses from manure (2) review N-gaps, attributed to dinitrogen loss as the difference between directly measured N compounds summed as total N loss and indirectly measured N loss through a mass balance …
