background: this study is the first research investigating the possible effect of pulsed power signals on the characteristics of cortical bone by comparing the mechanical properties of this type of bone pre and post expose to pulsed power. methods: a positive buck-boost converter was applied to generate adjustable high voltage, high frequency pulses (up to 500 v and 10 khz). the functional beha...

Abstract—This paper presents analytical formulas, based on the “thin wire model”, for calculating the ELF (Extremely Low Frequency) sub-sea electromagnetic field produced by a submarine power cable. Two different models are studied: the first and simpler one (already present in literature) is based on the infinite sea model while the second and more realistic one, that we propose, takes into ac...

Studies have demonstrated that electromagnetic waves, as the one of the most important physical factors, may alter cognitive and non-cognitive behaviors, depending on the frequency and energy. Moreover, non-ionizing radiation of low energy waves e.g. very low frequency waves could alter this phenomenon via alterations in neurotransmitters and neurohormones. In this study, short, medium, and lon...

Investigations into the safety of ultrasonography in pregnancy have focused on the potential harm of ultrasound itself. However, no data have been published regarding the electromagnetic fields that ultrasound devices might produce. This study is the first to measure extremely low-frequency magnetic field (ELF-MF) exposure of clinicians and pregnant women during prenatal ultrasound examinations...

Although melatonin (MT) has been reported to protect cells against oxidative damage induced by electromagnetic radiation, few reports have addressed whether there are other protective mechanisms. Here, we investigated the effects of MT on extremely low-frequency electromagnetic field (ELF-EMF)-induced Nav activity in rat cerebellar granule cells (GCs). Exposing cerebellar GCs to ELF-EMF for 60 ...

The automated system was designed and developed for accurate and fast localisation of extremely low frequency (ELF) electromagnetic field (EMF) exposure to any particular brain region and therefore record for any changes in the EEG activity before and after stimulation. The automated system consisted of a general user interface (GUI) where the users had the ability to precisely control and move...

Dispersive Alfvén wave activity is identified in four dayside auroral oval events measured by the Freja satellite. The events are characterized by ion injection, bursty electron precipitation below about 1 keV, transverse ion heating and broadband extremely low frequency (ELF) emissions below the lower hybrid cutoff frequency (a few kHz). Largescale density depletions/cavities, as determined by...

background: in previous investigations, it has been clarified that electromagnetic fields (elf) can cause some changes in cellular behavior. the aim of this prospective study was to investigate the effect of magnetic field (mf) on human sperm parameters of motility, morphology, and viability. materials and methods: semen samples were collected from 12 fertile men, and were allowed to liquefy fo...
