In this paper, a compact UWB printed monopole antenna design is proposed. The monopole antenna has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38, and thickness of 1.52mm. The matching through the UWB response is satisfied using a reduced ground plane. The proposed antenna is fed by a 50 Ω unsymmetrical microstrip line. The ground plane is pri...

introduction: a growing number of muslim athletes now engage in international competition. this raises the question of the advice they should be given if a major event occurs during the month of ramadan. methods: a narrative review has been based upon books and extensive reviews completed by the author and other investigators. results: practical considerations hamper assessment of the effects o...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...

Photovoltaic performance is significantly affected by soiling on its covering surface, which strongly influenced tilt angle. This raises concern for the potential investor, policymakers, engineers, and local populace in regions where rate threats remain relatively unexplored. study investigated effect of dust accumulation PV, considering influence angle using a low-cost in-house developed stati...

background and aim: children with hearing loss and children with intellectual developme­ntal disorders have defects in organizing and sensory integration. the aim of this study was to evaluate the effects of hearing impairment and intellectual disability on children's static and dynamic balance. methods: this cross-sectional comparative stu­dy was conducted on 17 boys with congenital severe to ...
