In the aquatic environment and in engineered water treatment systems, organic contaminants can undergo oxidative and photochemical transformations. For an overall risk assessment, the toxicity of the resulting transformation products has to be investigated ...
District energy systems can potentially decrease the CO2 emissions linked to energy services, thanks to the implementation of polygeneration energy conversion technologies, connected to buildings over a network. To transfer the energy from centralized tech ...
Traffic simulation models are frequently used to support decisions when planning an evacuation. These models typically focus on traffic dynamics and the effect of traffic control measures in order to locate possible bottlenecks and predict evacuation times ...
For the first time solar disinfection of liters of water containing wild Salmonella sp. and total coliforms was carried out in a compound parabolic collector (CPC) photoreactor at temperatures of almost 50 degrees C. Using surface water with high turbidity ...
The strategy document « Vision Energétique de la Suisse en 2050 », established by the Center for Energy Policy and Economics of Swiss Federal Institute of Technology (ETHZ), reveals the first impacts of climate change and underlines the fact, that the incr ...
This paper discusses the role of actors in the transition towards an energy self- sufficient region in Güssing, Austria. Regions with the vision of energy self-sufficiency are often called “energy regions”. We identify and describe the states, phases and m ...
We consider the problem of optimizing a novel acoustic leakage detection system for urban water distribution networks. The system is composed of a number of detectors and transponders to be placed in a choice of hydrants such as to provide a desired covera ...
The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...
Human activity results in the production of a wide range of pollutants that can enter the water cycle through stormwater or wastewater. Among others, heavy metals are still detected in high concentrations around urban areas and their impact on aquatic orga ...
Combining bacterial bioreporters with microfluidics systems holds great promise for in-field detection of chemical or toxicity targets. Recently we showed how Escherichia coli cells engineered to produce a variant of green fluorescent protein after contact ...
