In copper heap leaching structures, the ore is leached by an acidic solution. After dissolving the ore mineral, the heap is drained off in the acidic solution using a drainage system (consisting of a network of perforated polyethylene pipes and gravelly drainage layers) and is, then, transferred to the leaching plant for copper extraction where the copper is extracted and the remaining solution...

Financialization refers to the over-arching presence of the interest of global finance in every sphere of economic life – be it real or financial. Neo-liberalism, globalisation and financialization are three distinct yet mutually inter-related processes which at the present time are furthering the cause of global capitalism world over. The labour ultimately remains the risk-bearing factor in al...

There is a disagreement in the literature as to the intermediates and final products of the photo­ chemical reaction of diluted aqueous solutions of K4Mo (CN) 8 . In the article we give arguments to support our view that the formula of the red intermediate ion is [Mo(CN)8(H2O)2] 40. In parti­ cular we give an answer to recent objections by P e r u m a r e d d i against such an interpretation. I...

We show that the first betti number b1 (0) = d im H 1(0, !R) of a compact Riemannian orbifold 0 with Ricci curvature Ric(O ) ~ -(n 1)k and d iameter diam(O) :5 D is bounded above by a constant r (n, kD2 ) ~ 0 , depending only on dimension , curvature and diameter. In the case when t he orbi fold has nonnegative Ricci curvature, we show that the b1 (0) is bounded above by the dimension dim 0 , a...
