This study compares three farm-scale biogas utilization pathways—combined heat and power (CHP), biogas upgrading, and bio-methanation—using process simulation and life cycle assessment to identify the most suitable option for on-farm application. Bio-methanation showed the highest practical energy efficiency, …

The integration of biomethane into existing gas distribution networks is a key component of the energy transition, but its implementation is often limited by local network constraints. This study investigates the impact of local pressure losses on biomethane injection capacity in a real-world low-pressure …

Ammonia is a major nitrogenous constituent of municipal wastewater and poses environmental challenges when discharged to receiving waters. Conventional biological treatment processes can be limited by operational instability, sensitivity to loading conditions, and greenhouse gas emissions, motivating …

With more emerging technologies for hydrogen storage, it has become more important than ever to properly evaluate different options to ensure technical feasibility and legal compliance. In this study the technical aspects and legal requirements of two main storage technologies: underground gas cylinders …

Inleiding De vraag of gezondheidsverschillen over tijd groter of kleiner worden is complex. Wij beschrijven een methode om veranderingen over de tijd te toetsen, toegepast op verschillen in overgewicht tussen opleidingsgroepen. Methode De jaarlijkse gezondheidsenquêtes (1999–2023) zijn gebruikt voor …

Objectives Compassion-based interventions, like Mindfulness-Based Compassionate Living (MBCL), are increasingly recognized as treatments for depression. This study explores the impact of MBCL on self-schemas. Methods As part of an RCT on MBCL for depression, self-description interviews of approximately …

Labor market demands are changing considerably amidst modern developments. Furthermore, societies are becoming increasingly diverse economically, socially, and culturally. Transformative learning is needed to address these economic and societal challenges and capitalize on the increasing diversity in …

Building energy performance is largely determined during the early conceptual design stages. However, energy evaluation is often postponed until after key architectural decisions—such as massing and façade configuration—have been finalized, limiting opportunities for meaningful optimization. This study …

Mijn dochter Anna was vier jaar toen we aanschoven bij haar eerste oudergesprek op de basisschool. Als kersverse ouders waren we nieuwsgierig. Hoe deed ze het? Had ze vriendjes gemaakt? Voelde ze zich veilig? Ging ze met plezier naar school? Vol verwachting namen we plaats tegenover de juf. Van dat gesprek …

Small wind turbines face significant challenges in achieving commercial viability due to lower efficiency and higher energy costs compared to utility-scale systems and competing renewable technologies. Counter-rotating dual-rotor wind turbines (CR-DRWTs) with dual-rotational armature configurations offer …
