The yields of chemical reactions are highly dependent on the mixing pattern between reactants. Herein, we report modification a meso-micromixing interaction reaction model which is applied in batch reactors by leveraging flow characteristics continuous reactors. Both experimental and model-predicted were compared using classical Villermaux–Dushman method self-designed split recombination reacto...

Among the Next-Generation Nuclear Plant (NGNP) designs, High-Temperature Gas-Cooled Reactors (HTGRs) are very attractive, due to their inherent safety features, high power conversion efficiency, and potential of providing high-temperature process heat. To perform a thorough study license these types reactors, sufficient information needs be provided about phenomena that occur during accident sc...

The review summarized the types, the geometry, and the design principle of pretreatment reactors at high solid loading of lignocellulose material. Among the reactors used, the explosion reactors and the helical stirring reactors are to be considered as the practical form for high solids loading pretreatment operation; the comminution reactors and the extruder reactors are difficult to be used a...

thoracic duct is a duct that drains the lymph from the cisterna chily into the venous angle of the cranial vena vava. thoracic duct in the horse is situated on the right side, but in rare cases the left thoracic duct has been reported. in this report the course and left position of the thoracic duct in an embalmed donkey is described. regarding many anatomical similarities between horse and don...

Anatomic variations in forensic extrahepatic bile ducts is common. Knowledge of extrahepatic bile duct variations is important for surgeons in order to prevent iatrogenic damage during surgery. This study aims to determine the variations in extrahepatic bile ducts among 150 cadavers located at the Kerman Medicine Organization. We performed autopsies on 150 cadavers. Bile ducts were exposed an...

This paper presents the results of an investigation into the treatment of Tehran Refinery effluents in UASB reactors. Four pilot-scale UASB reactors were built with similar dimensions, each with a volume of 45.78 1, and operated in parallel at 37 °C. The sludge seed was prepared from the waste activated sludge of the wastewater treatment unit of the refinery. The organic loading rates were grad...

Background The anatomy of the nipple has become clinically relevant. Diagnostic techniques access the breast through nipple ducts and surgeons offer nipplesparing mastectomy. There is variation in the number of ducts reported and little is known about the spatial location of ducts, their size, and their relationship to orifices on the surface. Methods Nipple specimens were taken from 129 consec...
