Urine diversion (UD) systems are an innovative concept towards a resource-oriented and water saving sanitation system. From Sweden the technology spread over Europe. Firstly, installed in some buildings where the users had a specific “environmental” motivation, the technology widened and is reaching now a broader public (e.g. SolarCity in Linz, Austria (Oldenburg et al., 2009), office building ...

An isolation system installed in a nuclear power plant (NPP) could increase seismic safety during events. On the other hand, more significant relative displacement may occur due to system. The risk be increased case of an interface piping that connects isolated and nonisolated structures. Therefore, it is necessary consider systems when evaluating isolated-NPPs. This study performed fragility a...

The Johns Hopkins Hospital in 1999 began to evaluate the safety and efficacy of chlorine dioxide for Legionella control in a potable water system in an acute care hospital environment. The evaluation includes chlorine dioxide, its by-products and their impact on Legionella and pathogenic bacteria, biofilm, medical and laboratory filtration systems, corrosion rates and the environment. The appli...

The clarification on the collapse mechanism of a caisson breakwater has been an urgent task in order to reduce damages caused by next millennium tsunamis. In this study, piping destruction of a mound induced by seepage flow is taken into consideration solely. A stabilized ISPH method proposed by Asai (2012) is adopted with some modification associated with the extended Darcy law (Akbari 2013, 2...
