the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Theoretical and experimental evidences support the hypothesis that extremely low-frequency electromagnetic fields can affect voltage-gated channels. Little is known, however, about their effect on potassium channels. Kv1.3, a member of the voltage-gated potassium channels family originally discovered in the brain, is a key player in important biological processes including antigen-dependent act...
Background and Objective: Nitric Oxide in the small intestine causes relaxation of smooth muscles. Research indicates that extremely low frequency electromagnetic fields (ELF) affect nitric oxide level in the tissues. The objective of this study was to grasp the effect of prolonged exposure to ELF on the nitrergic system in the small intestine. Materials and Methods: 21 adult male rats were ...
the efficacious effects of pulsed electromagnetic field (pemf) under the certain field parameters like frequency and the field intensity have been reported for various tissue and molecules. since collagen is found abundantly in most tissue structures, this research was designed to further investigate the effects of extremely low frequency (elf) pemf on the synthesis of the epidermal collagen. t...
