CORROSION INHIBITION EFFICIENCIES OF POLYMERIC MATERIALS ON ALLOY STEEL IN DILUTE HYDROCHLORIC ACID AND SODIUM HYDROXIDE SOLUTIONS AT AMBIENT TEMPERATURE

A Decorating Class corrosion control test was conducted on alloy steel, using polymeric coatings (polyurethane, bitumen (medium airing), and high-density polyethylene) in dilute HCl solutions of pH values 4, 7, and 12, respectively for acid, neutral and alkaline solutions at ambient temperature.In the study, Eighty-four coupons of alloy steel were

The psychological consequences of epidemics/pandemics, such as the COVID-19 pandemic, include an increase in psychopathological symptoms, such as depression, anxiety, and stress, and negative emotions, such as fear.However, relatively little attention has been paid to how people cope with the pandemic.Coping is a multi-component process, helping to

Introduction.Lamentations remain an enduring national treasure of the Mordovian ethnos.They do not only offer the richest cultural and historical information, but also represent a living existence of the past in modern times.Based on the research and Co Q10 the folklore material, it gives a generalized characteristic of poetic devices and visual an

The island divertor has been proposed for power and particle exhaust in stellarators.It is investigated in the Wendelstein 7-X (W7-X) Cocktail Set experiment.The divertor capabilities such as particle exhaust or radiative power dissipation scale with the divertor density.However, significantly lower divertor density has been obtained in W7-X in com
