In the paper the methodology and test results of field and laboratory corrosion tests of steel earthing rods with zinc galvanized coatings and copperbonded coatings are described. The corrosion rate and level of corrosion damage of earthing rods with two different protective coatings have been compared as well some conclusions related to reliability and assessment of technical “life time” of st...

The field of HIV biology has been galvanized by the discovery of innate APOBEC3 cytidine deaminases, which pose powerful barriers to the replication of HIV and other retroviruses. Rapid progress has been made in understanding their mode of action, intriguing regulation within cells, expanded range of retroviral targets, and the counterstrikes utilized by retroviruses against them. While scienti...

In this paper, the behavior of corrosion in phosphated galvanized steel without defect and with surface is evaluated electrolyte solutions sodium chloride at a concentration 3% sulfate 0.1 M objective simulating marine environment presence chlorides, sulfates for industrial environment. experimental methodology, samples are used, each were exposed sulfate. The was electrochemical techniques Lin...

in order to provide the data needed for the design of saffron processing equipment, physical properties of its flower were investigated. these properties included dimensions, mass, true and bulk densities, porosity, static and dynamic coefficients of friction, and terminal velocity as a function of moisture content. the average range of these properties for the three different parts of saff...

Abstract Cold Metal Transfer (CMT) lap joint of Al6061-T6 and Galvanized steel is studied in this paper using design experiments method. Welding parameters considered for the work includes stick out distance (10 mm −14 mm), wire-feed speed (3.5 m min −1 – 4 ) torch angle (10˚ to 15˚). Weld strength optimized by Taguchi analysis optimizing input variables with 100% argon gas 14 overlap region 13...

The Lancet's 1998 publication of "Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children" by Andrew Wakefield, et. al., positing a causal relationship between MMR vaccine and autism in children, set off a media storm and galvanized the anti-vaccine movement. In this paper, centuries-old fears of vaccination and the history of autism as a medic...

INTRODUCTION Silicates have been used by the drinking water utilities for decades (Shuldener and Sussman, 1960). Initially, silicates were used for “red” water complaints in the distribution system. Control of zinc [from galvanized iron] and aluminum corrosion by silicates has also been described by early researchers (Lehrman and Shuldener, 1951, 1952). More recently, silicates have been found ...

The field of human immunodeficiency virus (HIV) biology has been galvanized by the discovery of innate APOBEC3 cytidine deaminases, which pose powerful barriers to the replication of HIV and other retroviruses. Rapid progress has been made in defining their action, intriguing regulation within cells, expanded range of retroviral targets, and counterstrikes utilized by retroviruses against them....

Typically, Sn cannot be finished on Ni and Ag surfaces via the immersion process. In this work, through galvanic reaction, finish was processed an coexisting with a surface. Herein, detailed mechanism of reduction Sn2+ ions surface reaction is reported. Through transmission electron microscopy X-ray diffraction analysis, uncommon Ag4Sn phase, instead common Ag3Sn confirmed to form during layer....
