The issue of using modern equipment in the construction and modernization electrical substations is discussed article. 
 current state substation analyzed. It shown that more than half has exhausted its technical resource. percentage refusals due to aging increased significantly. Modern trends design new concepts installation are described. complete-block technology considered. experience ...

The master equation for the reduced density matrix of a charged particle interacting with translation invariant weakly coupled environment is considered. electric current renormalized by system-environment interaction, leading to direct signature in bremsstrahlung. general solution given absence external electromagnetic field, and spread decoherence wave packet are followed. increased complexit...

The new 3-D numerical model studying evolution of force-free electric currents in the solar atmosphere is presented. The initial dipole magnetic field is considered in a simplified active region. Starting from a low electric current, which penetrates the photosphere, and increasing the current intensity, the path of force-free electric current and the corresponding magnetic field are computed. ...

TO THE EDITOR: Gratiy et al. (2013) proposed two alternative explanations for the nonbalanced current source density (CSD) estimates in Riera et al. (2012). Their commentary was based on a particular interpretation of the role played by the Ampere-Maxwell Law in the genesis of the electric fields for macroscopic media. In this Reply, we will provide further information to stimulate the debate i...

OBJECTIVES The aim of this work was to compare in vivo measurements of direct current (dc) and alternating current (ac) obtained from acupuncture points in Ukrainian and Mexican residents. METHODS Measurements were made using the method of Voll. The participants were 43 healthy Ukrainian and 71 healthy Mexican residents aged between 20 and 30 years, as well as 24 Mexican patients with a clini...
