Abstract Plasma photonic crystals designed in this paper are composed of gas discharge tubes to control the flow electromagnetic waves. The band structures calculated by finite element method consistent with experimental results which have two distinct attenuation peaks ranges 1?2.5 GHz and 5?6 GHz. Electromagnetic parameters plasma extracted Nicolson–Ross–Weir effective medium theory. measured...

Since regular radio broadcasts started in the 1920s, the exposure to human-made electromagnetic fields has steadily increased. These days we are not only exposed to radio waves but also other frequencies from a variety of sources, mainly from communication and security devices. Considering that nearly all biological systems interact with electromagnetic fields, understanding the affects is esse...

In a model of murine ventricular cardiac tissue in vitro, we have studied the inotropic effects of electromagnetic stimulation (frequency, 75 Hz), isoproterenol administration (10 μM), and their combination. In particular, we have performed an image processing analysis to evaluate the kinematics and the dynamics of beating cardiac syncytia starting from the video registration of their contracti...

background: considerable attention is focused on effects of electromagnetic field (emf) and its increasing use in everyday life. appliances and various equipments are sources of electromagnetic fields with a wide-range of technical characteristics. objective: in this study we investigated the effect of emf (50 hz, 0.5 mt) on epididymis and deferens duct in mice. materials and methods: 30 balb/c...

The control valve operates at high operation frequency (up to 1,000 Hz) in the large pressure differences between the inlet and outlet of the valve. The flow and operation characteristics of a high-speed electromagnetic control valve are investigated using a commercial software, CFD-ACE+. It is found that maximum operation frequency of the control valve depends on the applied electromagnetic fo...

Objective: Much attention is paid to angiogenesis due to its mutual role in health and disease. Therefore, the effect of various chemical and physical agents on inhibition of this process has been recently studied. This study was conducted to investigate the synergic effect of glycyrrhizic acid and electromagnetic field on angiogenesis. Materials and Methods: In this experimental study, 44 Ross...

INTRODUCTION The effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (ELF/EMFs) effects including mechanism of their interaction with live organisms and also their possible biological applications still re...

BACKGROUND Obsessive-compulsive disorder (OCD) is associated with cognitive dysfunction. Although there are several studies focused on the neurobiology of OCD, little is known about the biological correlates of the cognitive deficit linked to this disorder. The aim of our study was to examine the association between cognitive impairment and current source density markers in patients with OCD. ...

Cell samples of the yeast Saccharomyces cerevisiae were exposed to 100 J/m2 of 254 nm ultraviolet (UV) radiation followed by a 30 min treatment with ultra-wide band (UWB) electromagnetic pulses. The UWB pulses (101-104 kV/m, 1.0 ns width, 165 ps rise time) were applied at the repetition rates of 0 Hz (sham), 16 Hz, or 600 Hz. The effect of exposures was evaluated from the colony-forming ability...
