background & aims of the study: corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. the aim of this study was to assess the corrosion and scaling potential of drinking water resources in babol city, iran. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calcium hardness, ph, total alkalinity...

Corrosion resistance of zircon reinforced alumina refractories has been carried out through static crucible test. The corrosion measurements with percentage, the penetration depth of molten steel and the microstructure of the refractories were evaluated after soaking 150 h at the temperature of 1500˚C. Results showed that the corrosion resistance of alumina increased by adding 20 wt% zirc...

In this paper, the fractal dimensions are proposed for characterizing the optical fiber corrosion sensors, which is applied to measure the steel corrosion based on Fe-C alloy film. Because corrosion was a complex random phenomenon and the corrosion surface of Fe-C alloy film of the optical fiber corrosion sensor possessed fractal characteristics, the image fractal dimensions is as a quantitativ...

   In this research, mesoporous silica was served as the host of molybdate (corrosion inhibitor). The loaded mesoporous silica was dispersed in a paint matrix. The composite was then coated on the carbon steel surface. Polarization and electrochemical impedance spectroscopy (EIS) tests showed that the corrosion resistance of the scratched paint containing molybdate loaded mesoporous silica ...

1. The influence of anxiety symptoms on autonomic nervous system cardiovascular control has never been studied in hypertensive subjects. This study was designed to verify the presence of sympathetic hyperactivity in hypertension associated with anxiety symptoms. 2. Neuroautonomic cardiovascular control was evaluated using short-time power spectral analysis of RR and arterial pressure variabilit...

Ni-P Electroless coatings provide appropriate resistance to wear and corrosion. Co-deposition of particles between layers can improve their properties, especially general corrosion and erosion-corrosion behavior by means of nano diamond as reinforcing particles. In this study Ni-P/nano diamond composite deposition were deposited on steel substrate. Structure of the coatings and corrosion r...
