Experimental and Numerical Simulation of Water Hammer in Water Conveyance Pipeline and Effect of Surge Tower Pipe in Controlling this Phenomenon

Water hammer is one of the unsteady flows in urban water distribution networks, which has been of great importance due to the damage caused to the pipeline and has always been of interest to researchers. In this study, the phenomenon of water hammer due to the sudden closure of the valve in the downstream end has been investigated in a laboratory and using a numerical model. In the laboratory s...

Psychological effects of patient surge in large-scale emergencies: a quality improvement tool for hospital and clinic capacity planning and response.

I-25: GnRHa Trigger State of the ART -Towards the OHSS Free Clinic

Human chorionic gonadotropin (hCG) has been used as a surrogate for the mid-cycle LH surge for several decades. Due to structural and biological similarities with LH, hCG binds to and activates the same receptor - the LH/hCG receptor. However, despite the fact that hCG effectively secures final oocyte maturation and ovulation, its use as a surrogate for LH has got several drawbacks - first and ...
