In a new hydrometallurgieal process for recovery of lead from lead oxide secondaries, liquid effluence is minimized by jointly treating contaminated was~ting water and leaehant bleed. To enable internal recycling of the leachant bleed and recover pure water, it is necessary to incorporate a concentration unit. In this paper different technologies for concentrating the mixed stream are compared....

The need for treatment of dilute metal contaminated water as a residual from mining and mineral processing facilities is ubiquitous. Electrochemical technologies have the potential to provide selective and measurable recovery of base metals from dilute mining influenced water. However, the technology is currently not widely used in the treatment of mining influenced water (MIW). The principles ...

The petroleum industry requires the best materials to reverse the rock wettability to water-wet state which give significantly improved oil recovery.Nanoparticles are suggested as enhanced oil recovery potential agents to decrease viscosity and alter the wettability of reservoir towards more water-wet. This study provides new insights into CuO nanoparticles effects on wett...

The aim of the present study is to test the hypothesis that sprint swimming performance is enhanced by in-water passive recovery (IN) after sprint swimming bouts in well-trained adolescent swimmers. Using a randomized crossover study design, twelve well-trained adolescent swimmers performed two tests at the swimming pool after preliminary testing. They performed 5 bouts of 100m all-out swimming...

The aim of this study was to determine the effect of 3 post-match recovery modalities on physical performance, physiological measures, and players' perceptions of recovery after 90-minute soccer match play. On separate days, 28 young (age: 14.3 +/- 0.7 years) soccer players played 3 soccer matches each randomly followed by 1 of 3 recovery modalities: (a) CONT-cold (12 degrees C) water immersion...

This study assessed the effectiveness of water immersion to the shoulders in enhancing blood lactate removal during active and passive recovery after short-duration high-intensity exercise. Seventeen cyclists underwent active water- and land-based recoveries and passive water and land-based recoveries. The recovery conditions lasted 31 minutes each and started after the identification of each c...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...
