Introduction: Anterior cruciate ligament (ACL) reconstruction is a common surgery to treat an ACL injury which is indicated for a person to return to sports activity and patient’s with symptomatic knee instability. Several patients’ and injuries’ related prognostic factors before ACL reconstruction (ACLR) have been suggested to be associated

Heavy metals such as lead, predominantly associated to wastewater effluents from the semiconductor industry, are harmful to the environment and human health. The utilization of polymeric membrane has been reported in numerous investigations on wastewater management of heavy metals. Therefore, this study aims to remove lead from wastewater effluent

A good ventilation system is essential for an underground shelter to provide a comfortable environment with better indoor air quality. Ventilation shafts are widely used for ventilation purpose in an under- ground shelter. In the current work, the position of the ventilation shaft is optimized by employing the Response Surface Methodology (RSM). Tw

The impact of global warming has urged a prudent spending of energy in the building sector nowadays. In general, a typical HVAC system consumes about 60%e70% of the total energy consumption of a building. Therefore, designing an energy-efficient HVAC system is essential to alleviate the worsening greenhouse effect. Recent research works have report

The main aim for Islamic Education is to produce a ‘good man’ in all his personality aspects. This study aims to determine the level of secondary school students’ motivation in learning Islamic Education subject, and to examine the factors influencing their motivation using the cross-sectional survey design. The study sample consisted of (170

Malocclusion is one of the most common craniofacial problems observed worldwide. Affected individuals suffer not only from aesthetic concerns but also from functional problems, such as with mastication and pronunciation. The prevalence of malocclusion in East Asians is higher than in other races. Reports have shown besides environmental factors, th

We consider the λ model, a generalization of the Potts model, with spin values {1, 2, 3} on the order-two Cayley tree. We describe the model ground states and prove that translation-invariant Gibb measures exist, which means that a phase transition exists. We establish that two-periodic Gibbs measures exist.Theoretical and Mathematical Physics, 19

In this paper, we consider the λ-model on Cayley tree for order two with Potts competing nearest-neighbor and prolonged next-nearest neighbor-interactions. We described the construction of the Gibbs measure for the considered model. We proved the existence of the translation-invariant limiting Gibbs measures for the model.λ-model with competing P

Ultra-long Raman fiber lasers are of significant interest due to their application in the telecommunications industry. In this work we propose a self-pulsing ultra-long Raman fiber laser with a ring cavity configuration. A TrueWave® REACH fiber is deployed as the gain medium for the Raman fiber laser. Three laser cavities with different total cavi

Fish feeding system has three methods; manual, automatic and demand feeding. Demand feeding system serves feeds to fish, when fish switch on feeders. Although demand feeding system has advantages, there are still some problems; e.g. social status in fish. A few fish occupy the actuation of switch of the feeder, so results show the variation in fish
