The die-off of the long-spined sea urchin Diadema antillarum in the 1980s highlighted its crucial role as a primary grazer in tropical western Atlantic coral reefs. However, natural recovery has been slow, exacerbated by a new die-off in 2022. Interest in actively restoring D. antillarum populations …

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 …

Coastal flood managers seek to anticipate future flood risk and as a result consider the adaptation of flood defences. Instead of crest heightening, dikes can be adapted to include hydrodynamic reducing vegetated foreshores to form a nature-based hybrid flood defence, for instance; at managed realignments. …

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 …

High level circular use of post-consumer insulating glass units will contribute to lower the environmental and social impact of insulation glass industry. The application of various circular strategies for insulating glass units (IGU’s) is rising. The product age will give an indication of the remaining …

Music can have a positive effect on the quality of life of people with dementia (PwD). Unfortunately, PwD have limited access to music due to difficulties in product use and loss of initiative. Most studies on designing for PwD focus on improving the interaction design and do not consider the loss of …

The age estimation of biological traces is one of the holy grails in forensic investigations. We developed a method for the age estimation of semen stains using fluorescence spectroscopy in conjunction with a stoichiometric ageing model. The model describes the degradation and generation rate of proteins …
