Two giants of evolutionary theory, Sewall Wright and R. A. Fisher, fought bitterly for over thirty years. The Wright-Fisher controversy forms a cornerstone of the history and philosophy of biology. I argue that the standard interpretations of the Wright-Fisher controversy do not accurately represent the ideas and arguments of these two key historical figures. The usual account contrasts the maj...

This work investigates the breakup dynamics of solid agglomerates in a polymer compounding operation, by using computational fluid (CFD) simulations together with discrete element method (DEM) simulations. CFD are used to compute flow field and shear stress distribution inside 2D section typical internal mixer for compounding. DEM instead predict mechanical response detect critical viscous need...

A simplified population balance model has been developed to predict the Sauter mean diameter, and optimize any breakage coalescence kernel. Firstly, shortcut is detailed, simplifying assumptions are argued. Then applied in a comparison of 60 combinations selection classical breakage, collision frequency efficiency kernels. The models fitted then compared with an experimental dataset measured tw...
