Isolated gastric Crohn's disease is unusual and a rare cause of pyloric outlet obstruction. If medical therapy is ineffective, patients may require surgery to relieve gastric outlet obstruction. Herein we describe a patient with isolated gastric Crohn's disease with pyloric outlet obstruction who was steroid-dependent and had a relapse despite receiving biologic and immunomodulatory therapy, bu...

Bottom outlets are significant structures of dams, which responsible for controlling the flow rate, operation, or removal reservoir sedimentation. The service gate controls outlet and whenever this is out order, emergency located at upstream utilized. cavitation phenomenon one common bottom outlets’ problems due to rapid transfer. present research a numerical study pattern in dam’s different op...

The unsteady three-dimensional numerical simulation calculation of the vertical axial flow pump device is performed based on CFD to examine pressure pulsation and energy distribution features water within siphon outlet conduit (SOC) under hydraulic coupling conduit. signals (PPS) monitoring points are decomposed using Hilbert–Huang approach via empirical mode decomposition (EMD) Hilbert spectru...

background: heavy metals have destructive and irreversible effects on the human, plants and animals. some industries in yazd enter industrial wastewater to municipal wastewater collection system. this can lead to high levels of heavy metals in wastewater and in turn in the wastewater treatment plant effluent.   methods: this study was carried out during four months from december 22, 2009 to may...
