في ظل الاهتمام المتزايد بتعليم اللغات الأجنبية وتعلمها، والانفتاح الثقافي والحضاري بين الشعوب والأمم، حرصت الدول المتقدمة والجمعيات العلمية والخبراء المهتمون بتعليم اللغات الأجنبية على ال
This study discusses the penetration of Islam in the Philippines, particularly the third wave of its expansion, which was brought by Sufi missionaries. It reinstates the historical relevance of Sufi ideas and approaches due to its contemporary relevance to the concept of social co-existence. The rational, intellectual and philosophical dimension of
In multiphase flow engineering operations, the pipelines that convey viscous fluids are subjected to interior friction where the pipe wall meets the fluid. The friction on the inner surface of the pipe causes energy losses. The losses are exhibited as a progressive pressure drop over the length of the pipe that varies with the fluid flow rate. This
During two-phase gas-liquid flow in pipelines, the fluids may take up different flow patterns. The exact nature of the flow pattern varies according to conduit size and geometry, fluids’ properties, and each phase’s velocity. When the conduit size and fluid properties are constant, then any changes in individual flow rates will result in change
Conventional chemopreventive agents causes adverse side effects in cancer patients. Thus, this study focuses on the effects of natural plant extract against cancer cell as a way to reduce or detrimental effects of orthodox drugs. The present study emphasizes on anti-cancer potentiality of Artocarpus altilis fruit extract against cervical cancer cel
It is in our interest to investigate the effect of the third nearest-neighbour binary interaction to the phase diagrams of the Potts model on a Cayley tree. Therefore, we generate and analyse the phase diagrams of the Potts model, considering prolonged competing binary interaction J2 and J3 on the same branch of the Cayley tree up to the third near
Experimental work has been conducted to study the infuence of gas injection on the phase inversion between oil and water fowing in a vertical pipe. A vertical transparent pipe test section line of 40 mm ID and 50 cm length was used. The test fuids used were synthetic oil and fltered tap water. Measurements were taken for mixture velocity, superfcia
Flow experiments have been conducted for two-phase flow in a vertical pipe. The experiments were made for highly viscous oil–water in a stainless pipe at 250 psig pressure through the laboratory-scale flow test equipment. The test section used is a vertical transparent tube of 50 cm length and 40 mm ID. The test fluid utilized in this experiments
We consider a Potts model on a Cayley tree with competing nearest neighbor J1 and next-nearest-neighbor interactions Jp restricted to spins belonging to the same branch of the tree with four spins and investigate the problem of phase transition for paramagnetic phases of this modeFull Terms & Conditions of access and use can be found at https:/
The accurate estimation of pressure drop during multiphase fluid flow in vertical pipes has been widely recognized as a critical problem in oil wells completion design. The flow of fluids through the vertical tubing strings causes great losses of energy through friction, where the value of this loss depends on fluid flow viscosity and the size of t
