We report the results of parsec-scale, multi-frequency VLBA observations of the core region of 3C 279 in Stokes I, linear polarization, and circular polarization. These full polarization spectra are modeled by radiative transfer simulations to constrain the magnetic field and particle properties of the parsec-scale jet in 3C 279. We find that the polarization properties of the core region, incl...

Synopsis : Colored films on the stainless steel, formed by the alternating current electrolyzing ( ACE) method and the conventional one ( INCO method) , have been studied to clarify the differences in the structure, rub resistance and polarization resistance of them. In the ACE method, the effects of electrolyzing patterns on the color tone and polarization resistance of the film have been inve...

The paper presents data on the study of electrocatalytic properties Ni–Mo thin films in neutral and alkaline media, obtained as a result electrochemical synthesis. Comparative characteristics deposited Ni-Mo various substrates different compositions with catalytic activity Ni, Pt St-3 were determined by method recording linear polarization curves determining slope Tafel curves. highest was exhi...

Polarization control of electromagnetic wave is very important in many fields. Here, we propose an active meta-mirror to dynamically manipulate electromagnetic polarization state at a broad band. This meta-mirror is composed of a double-layered metallic pattern backed by a metallic flat plate, and the active elements of PIN diodes are integrated into the meta-atom to control the reflection phas...

Buried metal objects in seawater may undergo corrosion because of the corrosive ions such as chloride present seawater. However, a paint coating control robots. Corrosion resistance mild steel 3.5 % sodium solution before and after with Asian guard red has been evaluated by polarization study AC impedance spectra. In presence paint, linear increases, current decreases, charge transfer double la...

RÉSUMÉ. La technique de résistance de polarisation linéaire (Rp) est utiisée de plus en plus fréquemment pour évaluer la cinétique de corrosion des aciers dans le béton armé. Cependant, la technique souffre d’un manque de fiabilité. Afin de mieux appréhender la physique de la mesure, des simulations numériques ont été réalisées. Plusieurs dispositifs ont été simulés. Ces expériences numériques ...
