As aging water distribution infrastructures encounter failures with increasing frequency, there is a real need for integrated, on-line decision-support systems based on continuous in-network monitoring of hydraulic and water quality parameters. Such systems will form the basis of a Smart Water Grid, allowing water utilities to improve optimization of system operation, manage leakage control mor...

introduction: the provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. root-end resection, preparation and obturation should provide an adequate apical seal. the aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of thes...

A project to assess the levels of leakage in 30 water utilities throughout South Africa was initiated by the Water Research Commission. The BENCHLEAK software was used to evaluate the water utilities and performance indicators calculated by the model were used to compare levels of non-revenue water. Results showed that utilities ranked differently according to the different indicators, and that...

A defunctioning loop ileostomy is often used to reduce the consequences of anastomotic leakage, especially in a low rectal anastomosis. Hanna et al. [1] showed that fecal diversion could be recommended as a selective tool to protect or ameliorate an anastomotic leak after a colorectal anastomosis. Tan et al. [2] also argued that the creation of diverting stomas could potentially minimize the fa...
