Manipulating powders still entails some clumsy and risky operations even now in the middle of fourth industrial revolution. This is because there a lack well-understood theory about granular matter due to its ravelled complexity. However, second most handled material by man after water thus ubiquitous daily life industry only water. Since eighteenth century, mechanical chemical engineers have b...

The microtubule (MT) cytoskeleton orchestrates the cellular plasticity and dynamics that underlie morphogenesis and cell division. Growing MT plus ends have emerged as dynamic regulatory machineries in which specialized proteins-called plus-end tracking proteins (+TIPs)-bind to and control the plus-end dynamics that are essential for cell division and migration. However, the molecular mechanism...

The paper describes first the theoretical framework of a “single layer” three phase material. The formulation is general and particular cases are dry and fully saturated soils. The formulation and discretization of the motion and balance equations is presented. Two constitutive equations are used in the applications described: A brittle model for saturated soils and a Mohr-Coulomb elastoplastic...
