Tungsten carbide-cobalt hard metal scrap was recycled to obtain high purity spherical tungsten powder by a combined hydrometallurgy and physical metallurgy pathway.Selective leaching of tungsten element from hard metal scrap occurs at solid / liquid interface and therefore enlargement of effective surface area is advantageous.Linear oxidation behav
The human pressure upon an alluvial river in the Mediterranean region has changed its riverine and deltaic landscapes.The river has been channelized in the last 70 years while the delta has been retreating for more than a century (a set of data unknown, so far).The paper concentrates on the AOR ZYMES fluvial component, trying to connect it to the d
This paper focuses on a model for increasing the power generation of a hydroelectric power station using the combined application of hydrokinetic turbines installed at the tailrace of the existing dam.Hydrokinetic turbines Flag will capture additional power from the energy remaining in water currents exiting draft-tube outlets and tailrace of the d
This study explores bioplastics fabrication based on alginate polymer with added glycerine as a plasticizer, creating Flag flexibility, and organic waste was used as a filler avoiding shrinkage.Exploratory, observational and experimental, Literature Review, amongst other methods, were used within a Qualitative and Quantitative Methodology by Design
