the corrosion inhibition characteristics of two synthesized schiff bases, namely n, n´-bis(2-hydroxy-6-nitrobenzaldehyde) benzidine  and n, n´-bis(salysylaldehyde) benzidine, on the mild steel corrosion in 2.0 m hydrochloric acid have been investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. these studies were carried out at different ...

lung cancer is still diagnosed in advanced stage and most patients do not have the opportunity for surgical treatment. although in the recent years new diagnostic equipment is available such as the radial and linear endobronchial ultrasound (ebus) and electromagnetic fiberoptic bronchoscopy. however; novel targeted therapies with tyrosine kinase inhibitors of second generation and immunotherapy...

Industry 4.0 (I4.0) adoption in the manufacturing industry is on rise across world, resulting increased empirical research barriers and drivers to I4.0 specific country contexts. However, no similar studies are available that focus South African industry. Our small-scale interview-based qualitative descriptive study aimed at identifying factors may inhibit sustainable of country’s The probed vi...

A pilot heat exchanger – cooling tower prototype was constructed and used for the evaluation of scale inhibitors in the inhibition of calcium carbonate (CaCO3) precipitation and deposition. The chemical additives that were used as inhibitors were 2phosphonobutane-1,2,4-tricarboxylic acid (PBTC, Dequest 7000), bis(hexamethylene triaminepenta (methylenephosphonic acid)) (BHPMP, Dequest 2090) and ...
