background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...

High temperature operation (500 °C and higher) of integrated circuits offers important benefits to harsh environment applications such as aerospace, aeronautics, and energy production. SiC-based electronics are a promising solution to this need for high temperature operation. However, thermally activated degradation of materials used in conjunction with SiC (such as interconnect metals and insu...

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...

Low-cost multijunction photovoltaic devices are the next step in solar energy revolution. Adding a bottom junction with low bandgap material through plasma enhanced chemical vapor deposition (PECVD) processing could potentially provide low-cost boost conversion efficiency. A logical candidate for this is germanium. In work we investigate growth of PECVD processed hydrogenated amorphous/nano-cry...

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...

in this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thick...

Nanocrystalline graphite (NCG) layers represent a good alternative to graphene for the development of various applications, using large area, complementary metal-oxide semiconductor (CMOS) compatible technologies. A comprehensive analysis physical properties NCG layers—grown different time periods via plasma-enhanced chemical vapour deposition (PECVD)—was conducted. The correlation between meas...
