We study how functional constraints bound and shape evolution through an analysis of mammalian voltage-gated sodium channels.The primary function of sodium channels is to allow the propagation of action potentials.Since Hodgkin and Huxley, mathematical models have suggested that sodium channel properties need to be tightly constrained for an action
This study aims to investigate the effect of changing skins material on the strength of sandwich plates with circular hole cyma sport m4 airsoft aeg when subjected to mechanical loads.Theoretical, numerical and experimental analyses are done for sandwich plates with hole and with two face sheet materials.Theoretical analysis is performed by using s
