As Vehicle-to-Everything (V2X) communication technologies gain prominence, ensuring human safety from radiofrequency (RF) electromagnetic fields (EMF) becomes paramount. This study critically examines human RF exposure in the context of ITS-5.9 GHz V2X connectivity, employing a combination of numerical …

In this work, in situ measurements of the radio frequency electromagnetic field exposure have been conducted for an indoor massive MIMO 5G base station operating at 26–28 GHz. Measurements were performed at six different positions (at distances between 9.94 and 14.32 m from the base station), of which …

De asfaltindustrie staat voor een opgave om te verduurzamen zodat er minder broeikasgassen worden uitgestoten. Hiervoor zijn meerdere ‘kleine stapjes’ noodzakelijk om uiteindelijk het einddoel te bereiken, klimaatneutraal werken in 2050. Momenteel wordt er al asfaltgranulaat hergebruikt in nieuwe asfaltmengsels …

Econsultancy heeft in opdracht van Nikkels projecten een archeologisch onderzoek (bureau-, boor-, proefsleuf- en definitief onderzoek) uitgevoerd in het plangebied aan de Binnenweg te Wilp in de gemeente Voorst. In het plangebied worden 43 nieuwbouwwoningen gerealiseerd. Bij de daarbij behorende graafwerkzaamheden …

The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at …

Sustainable urban drainage systems (SuDS) or nature-based solutions (NBSs) are widely implemented to collect, store and infiltrate stormwater. The buildup of pollutants is expected in NBSs, and Dutch guidelines advise monitoring the topsoil of bio-swales every 5 years. In the Netherlands, almost every …

Objective. After laryngectomy, the breathing resistance of heat and moisture exchangers may limit exercise capacity. Breathing gas analysis during cardiopulmonary exercise testing is not possible using regular masks. This study tested the feasibility of cardiopulmonary exercise testing with a heat and …

Abstract. Although the U-value of glazing has improved significantly in the last decades, the thermal transmittance of windows remains relatively high compared to opaque elements of the thermal shell. Consequently, glazing has a relatively low interior surface temperature in the heating season, which …

Achtergrond Neuropsychiatrische symptomen (NPS) komen vaak voor bij getroffen personen en kunnen een uitdaging vormen voor (in)formele zorgverleners. Daarom worden ze ook wel uitdagend gedrag (CBs) genoemd. Sensortechnologie die context en gedrag meet, kan helpen om CB's op een objectieve manier effectief …

Aggregation into groups may affect performance of individuals through the balance and strength of facilitative versus competitive interactions. We studied in situ how seasonal variation in abiotic environment affects this balance for blue mussels, a semi-sessile species. We hypothesize that seasonal …
