We present a simple method to construct approximate analytical solutions of a class of non-linear dynamical mappings in Rd(d=1,2,…). This class is defined as a system of d non-linear first-order difference equations. This system is a discrete analogue of a system of d-first-order ordinary...

The radio frequency field levels of some Globacom and MTN telecommunications base stations in Makurdi metropolis were measured using electromagnetic field tester (EMF827 Lutron). Measurements were done at distances of 5.00, 10.00, 15.00 and 20.00 metres away from the base stations in the north,...

The water resulted from mining industry and coal processing is characterized by a high concentration in argillaceous colloidal suspensions, which do not precipitate free not even in weeks. Because the dispersion grade is high, these particles have a big specific surface, this explaining the high...

In this paper, we present an investigation into plasma density disturbances and electric field perturbations associated with China, Sichuan, Wenchuan earthquake of magnitude M = 7.9 that occurred on May 12, 2008, at 06:28:01 UTC. The DEMETER (Detection of Electromagnetic Emissions Transmitted...

The conductive channels formation and disappearance probability is investigated for thin films of thread-like structure polymers in the a-c field. Depending on the field strength and frequency and the channel orientation in the field the soliton solutions were obtained as well as the oscillatory...

In this work, the effects of the electric fields on the flame propagation and combustion characteristics of lean premixed methane–air mixtures were experimentally investigated in a constant volume chamber. Results show that the flame front is remarkably stretched by the applied electric field,...

During the last two decades and, particularly, in recent years, the photovoltaic sector has increased interest in the recovery of solar grade silicon (SOG). In order to further develop related technologies and to find suitable commercial applications for its recovery, it is essential to...

To investigate the microphysics mechanism and the factors that influence arc development along a polluted surface, the arc was considered as a plasma fluid. Based on the image method and the collision ionization theory, the electric field of the arc needed to maintain movement with different...
