A probability-based model is presented to estimate particle crushing and the associated grading evolution in granular soils during isotropic compression and prepeak shearing in biaxial tests. The model is based on probability density functions of interparticle and intraparticle stress (ie, particle normalized maximum shear stress and particle ...

Any change in the energetic cost of mammalian mastication will affect the net energy gain from foods. Although the energetic efficiency of masticatory effort is fundamental in understanding the evolution of the human masticatory system, nothing is known currently about the associated metabolic costs of chewing different items.

However, no resistance costs were also detected (Giacomini et al., 2014, Vila-Aiub et al., 2014). This difference can be explained by the fact that fitness costs associated with one physiological mechanism of resistance may be lower than costs resulting from two or more mechanisms in the same plant (Yu and Powles, 2014).

Due to cost considerations, quartz sand has commonly replaced ceramic proppant in the field. However, the significant crushing of quartz sand and its distribution as multiple particle sizes both before and after crushing, termed as particle size redistribution, raises concerns about its ability to meet the demands of the fracture network.

The optimization method discussed in this paper utilizes both technical and economic calculations in order to find the most profitable solution. The aim of the optimization is to maximize the gross profit of the crushing plant (ie, income minus production cost). The production cost is calculated using the process accounting method.
