Pressure Control in District Metering Areas with Boundary and Internal Pressure Reducing Valves [PDF]
Water Distribution Systems Analysis 2008, 2009 Despite operational improvements over the last 10-15 years, water utilities still are losing a significant amount of potable water from their networks through leakage. The leakage is managed on the one hand by reactive and proactive maintenance and on the other hand by pressure control to reduce background leakage from connection and joints. This paper

Study on the effect of the pressure characteristics of the cone throttle on the cavitation
The Journal of Engineering, 2018 According to the cone-type throttle valve is prone to cavitation, resulting in the reduction in the performance of the cone throttle valve. Here, a visual experimental platform for hydraulic cavitation is built, and the cavitation number of the conical ...

Valve exploiting the principle of a side channel turbine
EPJ Web of Conferences, 2017 The article deals with a side channel turbine, which can be used as a suitable substitute for a pressure reducing valve. Reducing valves are a source of hydraulic losses. The aim is to replace them by a side channel turbine.

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
