background chronic sacroiliac (si) joint pain constitutes 16% to 30% of the total prevalence of chronic low back pain, which is commonly unilateral. apart from conservative management, various interventional pain management procedures have been reported. intraarticular deposteroid injection has been described as the most evidence-based, but different various radio frequency (rf) procedures have...

Steel corrosion of bars in concrete structures is a complex process which leads to the reduction of the cross-section bars and decreasing the resistance of the concrete and steel materials. In this study, reliability analysis of a reinforced concrete beam with corrosion defects under the distributed load was investigated using the enhanced Hasofer-Lind and Rackwitz-Fiessler (EHL-RF) method base...

Iranian Light Source Facility (ILSF) RF system was conceptually designed based on ILSF requirements for a 3 GeV storage ring and 400 mA beam current at 500 MHz RF frequency. Considering the fact that  cavity construction is simpler at 100 MHz and advantages of reducing frequency provided an alternative of 100MHz RF system to be explored for ILSF. After a thorough study on the effect of reducing...

Resonant structure is one of the proposed methods in combining power in RF systems of  RF accelerators. In this structure, fabrication of RF power divider or combiner using coaxial and cylindrical cavity is important. In this study, two combiners, in the same frequency band, are designed and fabricated; and their results are compared. The experimental results confirmed the simulation results an...
