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...

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...

A roof provides protection to be safe from direct sunlight. From the shelter, shadow alone is not expected. Durability, sustainability, less life cycle cost, and low maintenance cost are expected from a selected roof. The world has a thirst to have a best roof. No roof will fulfil the requirement of humanity since the climatic conditions are different. Hence the roof should be selected accordin...

AIMS To evaluate hydrogen peroxide vapour (H2 O2 ) for its ability to inactivate Bacillus spores within a laboratory-scale heating, ventilation and air-conditioning (HVAC) duct system. METHODS AND RESULTS Experiments were conducted in a closed-loop duct system, constructed of either internally lined or unlined galvanized metal. Bacterial spores were aerosol-deposited onto 18-mm-diameter test ...

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 ...
