Aim Many long-term ostomates are ‘out-of-sight’ of healthcare, and it is unknown how ostomates deal with ostomy- related problems and how these problems affect their quality of life (QOL). The aim is to examine patient-related studies describing ostomy-related problems and their impact on the perceived …

Integrated photonic sensors are promising devices for various sensing applications due to their low cost, small size, and high sensitivities that can be reached. In this thesis, ring resonators and three-port Mach-Zehnder interferometer (MZI) devices fabricated on Silicon-On-Insulator were compared for …

Gas-phase diffusion is a widespread process in nature, for example diffusion of pollutants in the atmosphere. A special case of diffusion is the so-called Knudsen diffusion where a gas diffuses in the molecular flow regime. The theory for Knudsen diffusion is well-known therefore, diffusion experiments …

Anaerobic digestion (AD) can play an important role in achieving renewable goals set within the Netherlands which strives for 40 PJ bio-energy in the year 2020. This research focusses on reaching this goal with locally available biomass waste flows (e.g. manures, grasses, harvest remains, municipal organic …

GasTerra is, als exclusieve verkoper van het gas uit de Groningse bodem, een cruciale ketenpartner in de energiesector in Nederland. Om deze strategische positie goed te kunnen vormgeven wil GasTerra de beeldvorming in de Nederlandse samenleving over gas en GasTerra analyseren. Men wil inzicht in of …

Damen Shipyards is always on the lookout for new emerging niche markets. It appeared one of the most promising emerging niche markets is the offshore oil and gas infrastructure decommissioning industry. Therefore Damen produced a preliminary design of an offshore oil and gas infrastructure decommissioning …

The aim of this dissertation is to research if and how Lithuania’s LNG terminal could be a method to ensure energy security within the European Union. Lithuania’s energy position has been a very vulnerable one, and used to import 100% of its gas supply from Russia’s state monopoly Gazprom. In order to …

This report focuses on the feasibility of the power-to-ammonia concept. Power-to-ammonia uses produced excess renewable electricity to electrolyze water, and then to react the obtained hydrogen with nitrogen, which is obtained through air separation, to produce ammonia. This process may be used as a …

Reason’s typology of safety culture (i.e. Just, Informative, Learning, Flexible and Reporting cultures) is widely used in the industry and academia. Through literature review we developed a framework including 36 markers that reflect the operationalization of Reason’s sub-cultures and general organizational …

The energy efficiency and sustainability of an anaerobic green gas production pathway was evaluated, taking into account five biomass feedstocks, optimization of the green gas production pathway, replacement of current waste management pathways by mitigation, and transport of the feedstocks. Sustainability …
