In the framework of seismic precursor electromagnetic investigations, we analyzed the very low frequency (VLF) amplitude signals recorded by the Instrument Champ Electrique (ICE) experiment on board the DEMETER micro-satellite. The sun-synchronous orbits ... see more

Data from the European network of very low/ low frequency (VLF/LF) receivers has been used to study the response of the lower ionosphere to the earthquake of magnitude 5.5 in Vrancea area on November 22, 2014. Negative amplitude anomalies have been observ... see more

The neural network approach is proposed for studying very-low- and low-frequency (VLF and LF) subionospheric radio wave variations in the time vicinities of magnetic storms and earthquakes, with the purpose of recognizing anomalies of different types. We ... see more

The paper aims to clarify the effects of electromagnetic frequency on magnesium alloy AZ80 billets during low frequency electromagnetic casting. It proposes a mathematic model, verified against the temperature measurements obtained from AZ80 alloy bi... see more

ELF (Extremely Low Frequency) magnetic field is a spectrum of electromagnetic waves, where the frequency is less than 300 Hz and includes non-ionizing radiation. This study aims to examine the effect of exposure to ELF (Extremely Low Frequency) magnetic f... see more

A receiver station was installed at Nasiriyah (Dhi Qar University - Faculty of Sciences) to receive very low frequency (VLF) radio signals from transmitters around the world. VLF waves are excellent probes of the sudden ionospheric disturbance (SID); they... see more

During November 2017, an active source seismic survey was performed in Andaman sea to study the acoustic propagation characteristics. High power low frequency acoustic signals generated by 20-air gun array onboard ORV Samudra Ratnagar were recorded from I... see more

This paper deals with the peculiarities of functioning of murine erythron system under vibrational stress on the basis of experimental data about erythrocytes acid resistance. Experiments were made on the outbred male mice at about one age and weight that... see more
