Role of the ratio of tangential to normal stiffness coefficient in the behavior of vibrofluidized particles.

The selection of parameters in the contact law for interparticle interactions affects the results of simulations of flowing granular materials. The present study aims to understand the effect of the ratio of tangential to normal spring stiffness coefficient (κ) on interparticle contact behavior in terms of the rotational coefficient of restitution determined using data obtained from multiparticle simulations. The effect of κ on the profiles of the micro- and macroscopic properties of particles in a vibrofluidized bed is also investigated.

Intrauterine Viral Infections: Impact of Inflammation on Fetal Neurodevelopment.

Intrauterine viral infections during pregnancy by pathogens such as Zika virus, Cytomegalovirus, Rubella and Herpes Simplex virus can lead to prenatal as well as postnatal neurodevelopmental disorders. Although maternal viral infections are common during pregnancy, viruses rarely penetrate the trophoblast. When they do cross, viruses can cause adverse congenital health conditions for the fetus.
