The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

Abstract Gold parting enabled the production of very pure gold for various purposes from sixth century BC onwards, but analytical proof this pyrotechnical process is difficult. We describe a new approach identification purified combining silver and copper isotopic with trace element analyses. Parting experiments were performed gold-silver-copper alloys using classical salt cementation to invest...

Gold refineries are under pressure to revise their understanding of “integrity” beyond the physical cohesion gold products, in order integrate supply chain due diligence on human rights, labour conditions, and conflict financing as part what can be coined ethical integrity gold. This article interrogates how processes erasure, through material purification refining process, disclosure, certific...

We propose a 2D variable sized block matching algorithm with hierarchical exhaustive search to examine tissue deformations in dynamic musculoskeletal ultrasonograhy. Novel aspects include improved matching by updating reference and candidate blocks at each scale and the application area. Performance is quantified on controlled in vitro gold standard (groundtruth) sequences and clinical in vivo ...
