Because of its importance, the human body has evolved barrier systems to protect CNS tissue from the external environment. This barrier is a membrane composed of tightly apposed cells and is selectively permeable to specific molecules by way of membrane transporters.展开更多

By means of the combined-effect model proposed at earlier time, authors have deduced a formula of final rise limited by mechanical turbulence and therefore have concluded that the corresponding formula neglecting the accumu- lated effect of ambient turbulence is only its particular case. By analyzing the function relation of the various affecting factors with the plume rise in the existing equations, it is proved that the formula derived from the combined-effect model is the most reasonable and shows more conformity to the observations.展开更多
