Background: A positive association between obesity based on body mass index (BMI) and periodontitis has been reported. Fat tissue-related systemic inflammation acts as the link to periodontal comorbidities of obesity. However, the BMI is unable to distinguish fat and fat-free tissues. More precise measures …

Het concept Nationaal Plan Energiesysteem (NPE) heeft Martien Visser aangenaam verrast. Het NPE schetst voor Nederland een route naar een klimaatneutraliteit in 2050. “Een van de conclusies is dat de overheid nog meer zal moeten gaan sturen. Deels gebeurt dit natuurlijk al, zie EnergiePodium. Het pure …

Een kennisclip over de Sustainable Development Goals

In Europe, green hydrogen and biogas/green gas are considered important renewable energy carriers, besides renewable electricity and heat. Still, incentives proceed slowly, and the feasibility of local green gas is questioned. A supply chain of decentralised green hydrogen production from locally generated …

In elk beleidsstuk staat het: Nederland/Europa streeft naar betrouwbare, betaalbare en schone energie. In de praktijk komt betrouwbaar er nogal magertjes van af. “Natuurlijk beseft men in Den Haag en Brussel dat energiezekerheid van extreem grote maatschappelijke betekenis is. De gascrisis laat dit ook …

In de workshopserie in het project Coöperatief in Balans en de leergemeenschap Slimme oplossingen en netbalans is de afgelopen jaren veel gedaan en geleerd rondom flexibiliteit, curtailment, energieopslag en systeemintegratie. In deze laatste bijeenkomst willen we onderzoeken hoe we hier als coöperaties …

The transition towards sustainable and just food systems is ongoing, illustrated by an increasing number of initiatives that try to address unsustainable practices and social injustices. Insights are needed into what a just transition entails in order to critically engage with plural and potentially …

Steam generating heat pumps show great potential for reducing carbon emissions in the industrial sector. However, predicting their performance is challenging as the exergy destruction of e.g., compressors and expansion valves increases with the temperature lift and condenser temperature. With over seventy …

In view of the energy transition, it is important that engineering students are familiar with the concept of exergy and the added value of exergy analysis compared to energy analysis. Exergy analysis tells the truth about energy efficiency and exergy is directly related to sustainable development. This …
