A machining operation is basically termed a material removal process, where material is removed in the form of chips. In a machining operation, the output parameter is achieved by controlling various input parameters. This paper discusses the effects of various input parameters in abrasive Jet machining (AJM) on the output parameter(Metal Removal Rate [MRR).This paper presents an extensive revi...

This paper analyzes players’ long run behavior in evolutionary coordination games with one-dimensional local interaction and imitation. Different from Alós-Ferrer and Weidenholzer’s study (JET, 2008), players in our model are assumed to extract valuable information from their interaction neighbors only. It is found that the payoff-dominant equilibrium could survive in the long run with a positi...

introduction: it has been known for a long time in the french-speaking, but not the english-speaking literature that travel can exacerbate pre-existing psychosis. the purpose of this article was to review the literature on this subject and present recommendations for prevention. methods: for this narrative review of the literature on travel risks in individuals with pre-existing psychosis, appr...

this experiment was conducted to study the effect of nozzle types and the time of herbicide incorporation in soil on weed control, using split plot design by randomized block design. the main plots were soil and herbicide mixing time and the subplots were nozzle types with three replications. this study was performed in karaj station of seed and plant improvement institute, located 25 km west o...

 Abstract Background: Transtracheal jet ventilation is an alternative ventilatory approach in airway surgery. The purpose of this study was to compare respiratory efficacy of percutaneous transtracheal with endotracheal, low frequency jet ventilation during microlaryngeal surgery. Methods: Ninety ASA class I-II patients aged between 16 and 70 years undergoing elective microlaryngeal surgery wer...

This study aims to investigate the dynamics characteristics of liquid jet injected from a needle-free injection device by analyzing the the flow visualization from the high-speed video camera and the CFD calculation. This is to investigate the jet flow phenomena (e.g. penetration, dispersion, velocity) in the quiescent air and in the tissue simulant (20% polyacrylamide gel) as the further infor...

In the present work, a numerical simulation of two parallel turbulent jets was performed. The simulations were carried out by using the  standard, the  standard and the RSM models. A parametric study was also presented to determine the effect of the nozzles spacing and velocity ratio on the axial and transverse positions of the merge and combined points. Correlations between the various paramet...

In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
