The bactericidal activity of copper and its salts has been generally found to be of a low order in vitro by such authorities as Porter (1946) and Sprowls and Poe (1943). At the beginning of 1973 our attention was drawn to the fact that copper salts in certain concentrations had in fact been found to be toxic to gonococci. Fiscina, Oster, Oster, and Swanson (1973), working at the Mount Sinai Med...

The study of fluid dynamics due to the stretching surface is one most eminent topics its potential industrial applications viz. drawing wire and plastic films, metal polymer extrusion, fiber glass production. In present article, author going effects hybrid nanofluids flow on an inclined plate including CuO (Copper Oxide), Cu (Copper). Casson with a couple-stress term has been used in analysis. ...

In the process of zinc smelting, when chloride ion concentration exceeds 100 mg/L, it continuously corrodes electrode plate and affects stability electrodeposition process. Therefore, must be reduced below mg/L. Compared with other methods used to control reactions Cu(II), use copper slag produced in smelting without additives does not cause reverse dissolution; reduce cost, turn waste into tre...

This computational work explores the heat and mass transfer of copper water nanofluid flowing along an inclined plate with varying surface temperature concentration in presence a magnetic field radiation through permeable medium. The dimensionless governing equations are solved numerically using efficient finite-difference technique, which is fast convergent unconditionally stable. findings rev...

In this project, joining Ti-6Al-4V and AISI 304 dissimilar plates by laser-spot-welding method has been studied. In this regard, Ti-6Al-4V and AISI 304 plates, with a thickness of 0.7 and 0.5 respectively, were lap-welded using an interlayer of 0.2 & 0.3 mm copper and silver (pure silver). The process was done by 400Watt pulsed laser (Nd:YAG) using oncentric spot welding with 4mm diameter circl...

The most notable method of infection from Escherichia coli O157 (E. coli O157) is through contaminated food products, usually ground beef. The objective of this study was to evaluate seven cast copper alloys (61 to 95% Cu) for their ability to reduce the viability of E. coli O157, mixed with or without ground beef juice, and to compare these results to those for stainless steel. E. coli O157 (N...
