1. Influence of water level in mine sequencing applied to strategic mining planning
Abstract Developing mine sequencing involves a number of factors and a large amount of information, and consequently the profitability of the project will strongly depend on the production schedule. A mining project may be conditioned to non-optimal sequencing, which may affect the economic results of the project and also lead to an inadequate utilization of

2. CONCEPTUAL DESIGN OF NON-IDEAL MIXTURE SEPARATION WITH LIGHT ENTRAINERS
Abstract A method is proposed to study the separation of minimum-, maximum-boiling azeotropic, and low volatility mixtures with a light entrainer, to investigate feasible regions of the key operating parameters reboil ratio (S) and entrainer - feed flowrate ratio (FE/F) for continuous processes. The thermodynamic topological predictions are carried out for 1

3. A Kinetic, Equilibrium, and Thermodynamic Study on the Biosorption of Tl+ and Cd2+ by Eichhornia crassipes Roots Using Carbon Paste Electrode
In this work, Eichhornia crassipes roots were used as a modifier for carbon paste electrode in a biosorption study of thallium (Tl+) and cadmium (Cd2+) ions. The ions were accumulated on modified electrode surfaces at open circuit potential and analyzed by square wave anodic stripping voltammetry. Before the biosorption study, the effect of ratio of biomass

4. Endovenous ablation (radiofrequency and laser) and foam sclerotherapy versus conventional surgery for great saphenous vein varices
BACKGROUND: Minimally invasive techniques to treat great saphenous varicose veins include ultrasound-guided foam sclerotherapy (USGFS), radiofrequency ablation (RFA) and endovenous laser therapy (EVLT). Compared with conventional surgery (high ligation and stripping (HL/S)), proposed benefits include fewer complications, quicker return to work, improved qu

5. Quantificação de riscos na avaliação estéril/minério
A razão estéril/minério é um importante fator na exeqüibilidade de minas a céu aberto. Precisos modelos digitais de elevação topográfica e outras superfícies de interpolação bem delineadas são imprescindíveis nesse tipo de análise. Esse artigo apresenta uma combinação de krigagem ordinária, para construir um modelo tridimensional de cobertu
