We perform numerical simulations of a two-dimensional frictional granular system under oscillatory shear confined by constant pressure. found that the undergoes dilatancy as strain increases. confirmed compaction also takes place at an intermediate amplitude for small mutual friction coefficient between particles. depends on confinement pressure while little

Abstract Different particle properties, such as shape, size, surface roughness, and constituent material stiffness, affect the mechanical behavior of coarse-grained soils. Systematic investigation individual effects these properties requires careful control over other which is a pervasive challenge in investigations with natural The rapid advance 3D printing technology provides ability to produ...

the object of this cross sectional study was to determine the hcv subtype 3a envelope protein binding affinity with human leukocyte antigen. envelope 1 (e1) protein is one of the structural proteins responsible for entering the cells through the receptors. the binding affinity of e1 protein epitopes to the selected human leukocyte antigen (hla) class i alleles was investigated using the compute...
