Vacuum Treatment of Metal in the Process of Continuous Casting by Protasov AV* in Evolutions in Mechanical Engineering_ Vacuum Treatment Mini Review One of the promising areas of liquid steel processing is the development of metal vacuum treatment in the stream during continuous casting (flow Vacuum Treatment ). Several technological schemes of such processes have been developed, however, in practice, the only variant of the process has been implemented at the conditions of converter shop No-2 of Novo-Lipetzk Metallurgical Combine (NLMC) (Figure 1). The technology of flow vacuuming is based on the theoretical works of Professor G A Sokolov [1]. A steel ladle with a special jointing element covering the slide valve is installed on the supports of the CCM, then the hydraulic cylinder is attached to slide valve and the compressed air is given to assembling device.Then the slide valve is opened and vacuum chamber with the help of hydrocylinders is lifted to connecting with the ladle, whi...

  Is Rheology a Concern in GI Physiology? by Ravi Kant Avvari* in Evolutions in Mechanical Engineering_ Rheology Concern Introduction The small intestine is part of the gastrointestinal tract that interconnects the stomach at one end to the large intestine at the other end. As the bolus containing meal traverses the intestinal segments it undergoes rheological transformation as a consequence of digestive processes such as alkaline buffering, micelle formation, absorption of nutrients and water [1]. As the chyme (mixture of meal and gastric juice) enters the stomach through the pylorus (a valve interconnecting the stomach and the small intestine), the duodenum (first segment of the small intestine) responds to the acidic content of the chyme by buffering them with alkaline secretion of pancreas. Buffering action results in lowering the pH value of the contents, so the meal can be processed for further breakdown. Mucus secretion (a thick protective fluid) by the duodenal mucosa helps...
