In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

Magnetically confined plasma can be heated with high power microwave sources. In spherical torus the electron plasma frequency exeeds the electron cyclotron frequency (EC) and, as a consequence, electromagnetic waves at fundamental and low harmonic EC cannot propagate within the plasma. In contrast, electron Bernstein waves (EBWs) readily propagate in spherical torus plasma and are absorbed str...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

In this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. Bactericidal effect of the plasma jet is also investigated. To that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. Electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

enhanced oxidative stress in diabetes mellitus may contribute to the pathogenesis of diaetic complications. in this article, the stress oxidative generation has been studied in experimental diabetes by ferric reducing ability of plasma assay, a sensitive and simple method, and by other oxidative damage markers. the ferric reducing ability of plasma values as a total antioxidant capacity were si...

Introduction: Numerous studies have shown that enriched plasma protects myocardial cells against ischemia. The aim of this study was to evaluate the effect of rat enriched plasma by preconditioning, ischemia, and reperfusion on the differentiation of bone marrow mesenchymal stem cells (BMMSC) into cardiomyocytes. Methods: In this experimental and laboratory study, BMMSCs were extracted from th...
