various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

Mancozeb, a fungicide of a manganese-zinc ethylenebisdithio-carbamate (EBDC), was administered by gavage at doses of 200, 400, 600 and 800 mg/kg/day to female virgin mice for 30 days. The mice were autopsied on 31st day. Mice were also treated with similar doses for a period of 30 days and the treatment was withdrawn for a further period of 30 days for reversible study. The mice were autopsied...

Zinc deficiency is highly prevalent ranging from 10% to 30–40% of the population in developed and developing countries respectively. Low zinc level has been found be associated with 0.7% overall mortality 1.0% disability-adjusted life years (DALYs) worldwide. In turn, available research evidence shown that supplementation its can reduce risk preterm birth, promote physical development children,...

Abstract The primary goal of this work is to develop a technology that allows for the recovery metal values from waste products, thereby promoting wise and efficient use our nation's resources. To achieve goal, an industrial El Kriymat boiler fly Ash was used recovering its content vanadium, nickel zinc. About 97, 95 99% respectively these economic elements were first dissolved ash magnetic con...

recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after disasters are helpful....

Melaniuk-Wolny, Silesian University of Technology, Faculty of Energy and Environmental Engineering, Gliwice, Poland Complex analysis of concentration and form of occurrence such metals as Zn, Pb, Fe and Cu in slags formed during a current...

A defined mesophilic consortium including an iron oxidizing bacterium and a sulfur oxidizing bacterium was constructed to evaluate its ability for bioleaching a flotation concentrate from Andacollo mine in Neuquén, Argentina. Experiments were performed in shake flasks with a pulp density of 10% (w/v), using a basal salt medium containing ferrous iron at pH 1.8. The leaching solutions were analy...

The purpose of this study was to evaluate the influence of variables in a flotation technique for the recovery of Toxocara canis eggs from soil. The trials were done under standardized conditions on one gram of previously sterilized soil samples contaminated with 200 eggs of T. canis. The following variables were evaluated in serial steps: sieving; type of wash; time of stirring; resuspension o...

The disposal of scrap rubber, represented by retired tires, has achieved industrial achievements, but the handling brass-coated steel wire as a structural reinforcement in tires received little attention. A feasible and efficient method acquiring economical resources is proposed to extract copper zinc (Cu-Zn) from wire. With 20% ammonia, 10% hydrogen peroxide, liquid-solid ratio 10, brass coati...
