The potential public health risks of radiofrequency (RF) fields have been discussed at length, especially with the use of mobile phones spreading extensively throughout the world. In order to investigate the properties of RF fields, we examined the effect of 2.45-GHz RF fields at the specific absorption rate (SAR) of 2 and 10 W/kg for 4 and 24 h on neutrophil chemotaxis and phagocytosis in diff...
In this paper, the nonlinear conjugate map is applied based on the conjugate Hasofer-Lind and Rackwitz- Fiessler (CHL-RF) method to evaluate the reliability index using the first order reliability method of the embedded nanocomposite beam, which is made of a polymer reinforced with carbon nanotubes (CNTs). The structure is simulated with the Timoshenko beam model. The Mori-Tanaka model is appli...
با توجه به اهمیت و پتانسیل کاربردی تیوسمی کاربازون ها و کمپلکس های فلزی آن ها، در این کار تحقیقاتی سنتز، مطالعات طیفی، شناسایی ساختاری و بررسی فعالیت ضد باکتریایی یک لیگاند تیوسمی کاربازون و سیزده کمپلکس جدید گزارش شده است. پیریدوکسال تیوسمی کاربازون (h3l+cl-) از تراکم 4-فنیل تیوسمی کاربازید با پیریدوکسال هیدروکلرید تهیه شده و سپس کمپلکس های جدید [zn(oac)(h2o)hl].h2o، [cu(cl)hl].h2o، [ni(oac)(h...
Background and Aim: Considering the central role of low health literacy (HL) in causing health inequalities and the fast growth of university student populations, this study aimed to determine the HL and its related factors among university students. Materials and Methods: This was a descriptive-analytic cross-sectional study including 375 female students of Imam Khomeini International Univers...
In this paper, the feasibility studty of a new method of RF power coupling to acceleration cavity of charged particles accelerator will be evaluated. In this method a slit is created around the accelerator cavity, and RF power amplifier modules is connected directly to the acceleration cavity. In fact, in this design, the cavity in addition to acting as an acceleration cavity, acts as a RF powe...
The HL-LHC upgrade will use deflecting (or crab) cavities to compensate for geometric luminosity loss at low * and non-zero crossing angle. A local scheme with crab cavity pairs across the IPs is used employing compact crab cavities at 400 MHz. Design of the cavities, the cryomodules and the RF system is well advanced. The LHC crab cavities will be validated initially with proton beam in the ...
the aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. two types of sandwich composites with e-glass/kevlar/polyester resin facings and end-grain balsa wood as core have been produced by vacuum infusion processing (vip) and hand-lay up (hl) method. compression tests on...
New projects being implemented or planned at CERN, such as the LHC Injectors Upgrade (LIU), High-Luminosity (HL-LHC) Future Circular Collider (FCC), motivate change of several architectural paradigms in Low Level RF systems (LLRF). In upgraded Super Proton Synchrotron (SPS) LLRF, distribution RF, revolution frequency, settings and synchronization timings will rely on a deterministic link, White...
We investigate the collapse of granular rodpiles as a function of particle (length/diameter) and pile (height/radius) aspect ratio. We find that, for all particle aspect ratios below 24, there exists a critical height Hl below which the pile never collapses, maintaining its initial shape as a solid, and a second height Hu above which the pile always collapses. Intermediate heights between Hl an...
