Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...

The study of the generation metric perturbation in laboratory presents an opportunity to observe and understand more easily mechanisms at work gravitation. present will focus on generated by a light pulse, as it could be current ultrahigh power laser. Although very small magnitude, potential thus has advantages over that mass acceleration, such absence noise due nonuniform acceleration or abili...

A microscopic description of the interaction atomic nuclei with external electroweak probes is required for elucidating aspects short-range nuclear dynamics and correct interpretation neutrino oscillation experiments. Nuclear quantum Monte Carlo methods infer response functions from their Laplace transforms. Inverting transform a notoriously ill-posed problem; Bayesian techniques, such as maxim...

background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...

In gas insulation switch (GIS) substation, secondary devices such as line monitoring are placed in the switching field, and these electronic vulnerable to transient electromagnetic interference caused by operation. order facilitate measurement research of disturbance data under different working conditions, a simulation test device is developed this paper, which can be used simulate GIS substat...

introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...

Overhead transmission lines are influenced by different factors which are mostly electrical and mechanical. These factors can cause problems for lines, distortions in network and outage of line. In designing transmission lines mechanical properties are evaluated after selecting a suitable conductor and clearance with regard to electrical properties. In lines designing, an important mechanical p...
