The behavior of settling velocity and clustering bidisperse inertial particles in a turbulent channel flow is investigated through direct numerical simulation. particle-laden planar has friction Reynolds number at Re? = 180. Eulerian–Lagrangian method used to study the dynamic properties monodisperse with 16 different simulation sets, which are distinguished by Stokes numbers ranging from St+ 1...

Enhancing smallholder farmers’ access to reliable, ready, and direct marketing channels is a prerequisite for sustainable food supply poverty reduction in the developing countries including Ghana. However, it great challenge farmers This paper analyzes factors that influence rice participation, intensity of using primary data from 199 three rice-growing districts Northern Region A double hurdle...

introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...

Error exponent bounds for a noise free optical channel using a direct detection receiver are computed for the cases of Pulse Position Modulation (PPM) and for the basic channel with binary output and average intensity constraint. Some consequences are derived regarding the behavior of the interleaving scheme suggested by Massey, the optimality of the PPM format and the significance of the Ro pa...

Examination of directly frozen rough endoplasmic reticulum (ER) of retinal pigment epithelial cells by freeze-fracture and freeze-substitution revealed distinct paired transmembrane proteins associated with membrane ribosomes. Ribosomal subunits on intact ER membrane are directly visualized for the first time, providing a global view of the structure of the ribosome and the corresponding struct...
