There is ongoing discussion whether cellular or mobile phone has any effects on brain. The aim of this research is to investigate the effects of mobile phone use on left and right ear using electroencephalograph (EEG). The brain waves are analyzed using Wavelet transform and Fast Fourier Transform. Twenty subjects are studied after recording their EEG signals using International 10/20 system of...

introduction: over the last decade, exposure to electromagnetic waves due to base station antennas has increased. this study was planned to evaluate the effects of different electrical field strengths with 950 mhz waves of the gsm mobile phone system on the excitatory postsynaptic potentiation (epsp) slope of the dentate gyrus long-term potentiation (ltp). material and methods: twenty four naiv...
In this paper, we describe and analyze a corpus of speech data that we have recorded in multiple modalities simultaneously: facial motion via optical motion capturing, tongue motion via electro-magnetic articulography, as well as conventional video and highquality audio. The corpus consists of 320 phonetically diverse sentences uttered by a male Austrian German speaker at normal, fast and slow ...
Magneto-Photo-Thermo-Microstretch Semiconductor Elastic Medium Due to Photothermal Transport Process
Electro-magnetic-thermal-microstretch elastic mathematical-physical model of semiconductor medium is investigated. The governing equations are studied in the context photo-thermoelasticity theory during photothermal transport process. exposed to an external magnetic field and a beam laser. coupled between electromagnetic field, thermal, plasma waves when inertia-microstretch properties material...
The instability of longitudinal electro-kinetic wave that is propagating across the magnetic field B0 in ion-implanted group-IV semiconductor sample consisting of non-drifting electrons, holes, and negatively charged colloids is investigated. Using hydrodynamic approach, a compact dispersion relation D(ω, k) is derived for the same. The propagation and amplification characteristics of the wave ...
Introduction: The highest electromagnetic radiation pollution is related to the radiofrequency waves of mobile phones (1). Up to 70% of these waves can be absorbed by various tissues (2). Absorption of these waves can damage the body tissues by causing oxidative stress (3). Given that melatonin plays an antioxidant role, it seems that this hormone can have a protective effect on the hepato- tox...
