The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …

Sustainable urban drainage systems (SuDS) such as swales are designed to collect, store and infiltrate a large amount of surface runoff water during heavy rainfall. Stormwater is known to transport pollutants, such as particle-bound Potential Toxic Elements (PTE), which are known to often accumulate …

Marine debris is a growing global problem. Due to the wide ocean dynamics worldwide, predicting the transport of floating marine debris, such as plastic, is difficult. Although large-scale distribution patterns and accumulation zones are recognised and reproduced by numerical models, small-scale prediction …

Sustainable urban drainage systems (SuDS) such as swales are designed to collect, store and infiltrate a large amount of surface runoff water during heavy rainfall. Stormwater is known to transport pollutants, such as particle-bound heavy metals, which are known to often accumulate in the topsoil. In …

Urban flood prevention is an intensifying prerequisite of urban inhabitation due to a multiplicity of threats to population health and property. One of the components of urbanisation that can fail to fulfil its function and cause urban flooding is gully pot clogging. Frequently this is the result of …

Arsenic contamination of groundwater is a major public health concern worldwide. The problem has been reported mainly in southern Asia and, especially, in Bangladesh. Slow-sand filters (SSF) augmented with iron were proven to be a simple, low-cost and decentralized technique for the treatment of arsenic-contaminated …

Electrohydrodynamic atomization (EHDA) is a technique which uses the influence of strong electric fields to manipulate the break-up of a liquid, pumped through a capillary nozzle, into droplets. In this work, an extended description of a specific high flow EHDA mode, known as the simple-jet mode, is …

Water velocity in rearing units for Atlantic salmon post-smolt can influence fish robustness. Studies have shown that training at velocities between 1-2 body lengths/second (bl/s) increases disease resistance in salmonid species. Monitoring and timely adjustments to the water velocity during post-smolt …

This research is performed to give an advice for the current problem of Canada Feeder Lines regarding the purifier installation. This research has given an answer to the following main question: ‘’What is the best way to improve the cost-effectivity of the purifier installation on board of a 10.000 DWT …

Harbour porpoises (Phocoena phocoena) are the smallest cetaceans in the North Sea. They have recovered from being rare to nowadays being present throughout the year in numbers reaching to 80 000 in the Dutch sector or the North Sea. The only area where studies were conducted prior to the disappearance …
