Figure 5 Results in fresh Itaquera Granite using 54 kHz transducers with the direct method (a) and semi-direct method (b).. Kuzmickas (2013) used ultra- sound to evaluate

With regards to the froth imagery of copper lotation, this paper proposes that the wavelet multi-scale binary process can be adopted for extraction of the equivalent size

From the low stress curves generated in the isothermal tests, it was possible to obtain a critical strain that starts dynamic recrystallization, the peak strain for

paper presents a study that uses cyclic potentiodynamic polarization tests in a synthetic marine environment to investi- gate and compare the effect of tempering on corrosion for

The SWRC test with the flow pump is divided in water withdrawing stages (drainage cycle) or infusion stages (iniltration cycle), which causes suction to increase or decrease

Given the very nature of mining activity, the recovery of areas de- graded by mining is an attempt to provide a new use (sustainable) to the area after ceasing the

The results show that standardized ordinary cokriging is a better methodology for imprecise and biased data and produces estimates closer to the true grade block distribution,

when working with grooved wheels, concluded that the cutting temperature is reduced as the number of grooves on the wheel increase, which may be justi- ied by a more
