Objective(s): It is known that extremely low frequency-pulsed electromagnetic fields (ELF-PEMF) influence multiple cellular and molecular processes. Retinal pigment epithelial (RPE) cells have a significant part in the emergence and pathophysiology of several ocular disorders, such as neovascularization. This study assessed the impact of ELF-PEMF on the proangiogenic features of RPE cells. Mate...

The effect of gravitational wave cosmological wavelength on the lensing is investigated. When source, deflector, and observer are aligned in a highly symmetric configuration, an Einstein ring will be observed by observer. There no time delays between different locations absence wave. Otherwise, emerge if propagates through system. Previous studies demonstrated that delay resulting from source-d...

Background and purpose: Considerable increase on the use of electronic devices increased the rate of public occupational exposure to extremely low frequency electromagnetic fields. Assessment of exposure to these fields is highly important due to potential health hazards. This study aimed at investigating the magnetic flux emission from extremely low frequency electromagnetic fields around powe...
