During the past decade considerable evidence has been accumulated with regard to the biological effects, both in vivo and in vitro, of extremely low frequency electric and magnetic fields, such as those originating from residentially proximate power lines, household electrical wiring and diagnostic apparatus and therapy devices. Also, during the evolution process, all living organisms experienc...
In this work, the structural and magnetic properties of ingot and melt-spun Pr3Fe24.75Co2.75Ti1.5 compounds have been investigated. The structural characterization of the compounds, by X-ray powder diffraction, is evidenced for a monoclinic Nd3(Fe,Ti)29-type structure (A2/m space group). A 2-type FOMP have been observed in the magnetic AC susceptibility curves of the ingot and melt-spun compoun...
Introduction: The power transmission lines are the emission source of extremely low frequency (ELF) electromagnetic fields that are considered to have an adverse impact on human health. Therefore the aim of this study was to evaluate the amount of magnetic flux with extremely low frequencies (ELF) around high voltage power transmission lines in the western areas of Tehran in 2012. Material a...
The purpose of this paper is to present a new type of dynamic balancing system, having a driving solution of the rotating part based on magnetic interactions. The magnetic system also plays the role of an elastic bearing. In the first part of the article is presented the technical solution which allows the dynamic balancing evaluation depending on the radial displacement between two disks with ...
Magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. The most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (MRI) and heating mediators for cancer therapy. In...
Background: Leukemia is the most common cancer in children. We aimed to evaluate the association between exposure to magnetic fields and childhood leukemia. Materials and Methods: In this overview,the relevant articles evaluating the association between exposure to magnetic fields...
