In this study, 2-aminobenzoic acid (ABA) has been used as complexing ligand for simultaneousdetermination of metal ions by adsorptive cathodic stripping voltammetry (AdCSV), for the firsttime. Thus, a selective and sensitive procedure was presented for simultaneous determination oflead, cadmium and nickel using ABA and differential pulse-adsorptive cathodic strippingvolt...

This paper examines through qualitative study the effect of government regulatory restriction and repression on non-governmental organizations (NGOs) engaging in transnational advocacy. The focus is NGO’s advocacy activities, realm human rights, environment, labor development particular, using illustrations from Bangladesh Zambia. It finds that next to some NGOs disbanding moving towards servic...

Shunting work on sorting wagons is carried out steeper profiles and requires the operation of shunting diesel locomotives a higher power. Many operations use double traction in conditions highly outdated fleet locomotives. However, technology operating two substantiation its scope application. In this article, using example station “X”, disbanding trains from hump investigated ways: first exist...

We present a stochastic three-dimensional cellular automata model of aqueous corrosion. consider the cathodic reaction with dissolved oxygen and different concentrations oxidizer. study role stability passive layer its effect on kinetics, surface morphology, roughness metallic surface. The considers balanced spatially separated anodic reactions is capable illustrating control corrosion rate. Be...
