The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP-150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex 272.Chemorex CP-150 demonstrated an effective and selective extr...

Galaxies in clusters and groups moving through the intracluster or intragroup medium (abbreviated ICM for both) are expected to lose at least a part of their interstellar medium (ISM) by the ram pressure they experience. We perform high resolution 2D hydrodynamical simulations of face-on ram pressure stripping (RPS) of disk galaxies to compile a comprehensive parameter study varying galaxy prop...

artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

Speciation modeling is an essential tool to estimate the chemical composition of an aqueous sample and to assess the bioavailability and potential risks associated with metal contamination. It is also an indispensable alternative for quantifying the metal speciation when analytical techniques are not available. In this study, we tested the effectiveness of two models, WinHumicV and the Non-Idea...

The IFRS Interpretations Committee (the Committee) has finally issued its Interpretation on accounting for waste removal costs IFRIC Interpretation 20 – Stripping Costs in the Production Phase of a Surface Mine (the Interpretation). This Interpretation is effective for annual periods beginning on or after 1 January 2013. Entities will be required to apply its requirements for production phase s...

Skull stripping is a major phase in MRI brain imaging applications and it refers to the removal of the brain’s non-cerebral tissues. The main problem in skull-stripping is the segmentation of the non-cerebral and the intracranial tissues due to their homogeneity intensities. Numerous techniques were applied in the studies of skull stripping, most common are region growing and mathematical morph...

| We introduce a new multiaccess coding strategy called stripping CDMA for a LOOK AWGN channel. Stripping CDMA can be viewed as a generalization of the regular CDMA scheme to one that can achieve arbitrarily high bandwidth eeciency. It can also be viewed as a modiication of the pure stripping scheme to one that is suited for multiaccess channel with bursty users. In this scheme, each user is sp...

OBJECTIVE The objectives of this study were to compare the results of radiofrequency ablation (RFA) and stripping for large-diameter varicose target veins for the period of 1 year, based on a composite end point; to analyze the pain severity on a digital rating scale for 7 days after RFA and stripping; and to detect the factors affecting the level of postoperative pain using the cluster analysi...

The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...
