The operation owned by SOMINCOR, a subsidiary Lundin Mining, with maximum capacity 2.6 Mtpy for copper processing plant 1.0 zinc plant. From 2010 till end 2019, mine has accumulated 7.3 Mt waste rock 17 ...

OBJECTIVE The present study aims to explore the effect of zinc supplementation on lipid peroxidation and lactate levels in rats having diabetes induced by streptozotocin and subjected to acute swimming exercise. METHOD A total of 80 adult male rats of Sprague-Dawley type were equally allocated to 8 groups: Group 1, general control. Group 2, zinc-supplemented group. Group 3, zinc-supplemented,...

to study the effects of phosphate and zinc sulfate fertilizers application methods on the yield and yield components of maize under water stress a randomized complete block with split plot factorial arrangement with three replications at research farm of the bu ali sina university was conducted in 2014. three levels of irrigation after 60, 90 and 120 mm evaporation from evaporation a pan was as...

We examined the effect of zinc on rat neuronal nicotinic acetylcholine receptors (nAChRs) expressed in Xenopus oocytes as simple heteromers of alpha2, alpha3, or alpha4 and beta2 or beta4. Coapplication of zinc with low concentrations of acetylcholine (</=EC(10)) resulted in differential effects depending on receptor subunit composition. The alpha2beta2, alpha2beta4, alpha3beta4, alpha4beta2, a...

This work demonstrates an improved cell design of a zinc-silver/air hybrid flow battery with two-electrode configuration intended to extend cycling lifetime high specific capacities up 66.7 mAh cm-2 at technically relevant current density 50 mA cm-2. A approach combines the advantages both zinc-air and zinc-silver batteries enabling enhanced energy efficiency while maintaining capacity. pulsed ...

Background: One of the concerns of consumers of animal protein sources is the residues of heavy metals in meat. The accumulation of these elements in meat and the consumption by humans can cause acute and chronic disorders in the function of vital organs. Methods: For the estimation of cadmium, zinc and silver in the poultry meat products, 100 samples of chicken breasts, thighs, hearts and liv...
