Biogas production involves the complex process of anaerobic digestion in bioreactors. This paper presents numerical modeling results and analysis of bioreactors. We discuss research methodology, model geometry, internal bioreactor processes, and possible modifications. Two mathematical models and their …

The problem with investments in digital technology arise when much wanted and needed small companies and entrepreneurs have to invest in costly device the benefits of which are largely unforeseen, or unpredictable. An example of this is the use of 3D whole garment knitwear machines, there not only the …

Caribbean coral reefs are in rapid decline and artificial reefs are increasingly often deployed to restore lost three-dimensional structure. The majority of artificial reefs and other marine infrastructure is built from concrete, with Ordinary Portland Cement (CEM I) as the most important ingredient. …

With coral reefs in global decline and further threatened by growing anthropogenic impacts, effective strategies for restoring these critical ecosystems are increasingly sought after. In Caribbean reefs, where disease outbreaks and fishing pressure have reduced herbivore abundances and facilitated widespread …

We developed a lesson where students construct a qualitative representation to learn how clock genes are regulated. Qualitative representations provide a non-numerical description of system behavior, focusing on causal relation-ships and system states. They align with human reasoning about system dy-namics …

Small and medium-sized production companies face many challenges in decision making about planning, maintenance, and other operational processes due to challenges of high variety in customer demand, configurations of the production processes, technologies used and so on. Operation Digital Twinning is …

Dutch-German Collaboration on Hydrogen for Energy Transition Policymakers and Authorities from the Netherlands and Germany met at Euregio Rhine-Waal in Kleve, Germany earlier this month, to advance the role of hydrogen in building a sustainable future. Prof. Sadegh Seddighi from HAN University of Applied …

In recent decades, higher education institutions have undergone a profound transformation, expanding their missions from teaching and research toward a stronger societal engagement and impact. Within this context, Dutch Universities of Applied Sciences (UASs) offer a distinctive case: since the formal …

The University of Twente, Saxion University of Applied Sciences, ROC of Twente (vocational education), centre of expertise TechYourFuture and H2Hub Twente, in which various regional hydrogen interested corporations, like Demcon, VDL, HyMatters, KIWA, Cogas, Powerspex and Waterschap Vechtstromen, are …

This research analyzes best practices for the benefit of developing a financially sustainable, high-quality farmers’ cooperative under the Bonaire Platinum label, supporting the islands’ local food security and improved resilience of the food system by increased local production and local market resilience. …
