Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...
Objective- This study was done to give complete topographic information about the position of the lungs and trachea in European pond turtle using Computed Tomography (CT) and usual anatomic methods. Design- Experimental study Animals- 10 female, adult European pond turtles (Emys orbicularis) Procedures- All scans were obtained on a two detector scanner. In anatomical study eight tur...
Background and objectives: One of the most important components of rangeland ecosystems is soil that their degradation will reduce rangeland production capacity. About half of the world's lands are rangelands and they contain more than one-third of the biosphere carbon pool. Therefore, these lands have a high potential for carbon sequestration. This study was conducted to investigate the soil c...
Background and Aim: Natural disasters are a reality that has affected a significant part of rural areas today. Due to the fact that in some cases it is not possible to prevent the occurrence of these natural disasters, so it is very important to study the degree of resilience against natural disasters/ The purpose of this article is to investigate the resilience of residents of rural areas of K...
A thin liquid film subject to a temperature gradient undergoes thermocapillary convection because of the non-uniform surface tension at the free surface. This induced flow perturbs the film free surface and generate a free surface velocity field. These observable consequences can be thought of as the “signature” of the imposed temperature field and this work investigates whether the temperature...
in this survey, 55 patients were studied in a period of six years for having the anesthesia in the sitting position. in this position, the surgeon will had a better access to the location, whose damages have been sustained, so less damages would be given to the healthy tissues. for the patients, due to their critical general conditions, one week prior to giving anesthesia to the posterior fossa...
There are some critical privacy concerns in the current online social networks (OSNs). Users' information is disclosed to different entities that they were not supposed to access. Furthermore, the notion of friendship is inadequate in OSNs since the degree of social relationships between users dynamically changes over the time. Additionally, users may define similar privacy settings for their f...
