The flow model of single phase flow in the elbow of the vertical tubular leacher was studied by using NaCl solution tracing and microcomputer sampling.
Objective: To obtain the acellular matrix from tracheae of rabbits and Sprague-Dawley (SD) rats, acted as tubular scaffold for salivary gland organoid tissue engineering study.
Several patent techniques of Tsinghua University, tubular distributor and trictum structure, were adopted to improve the distribution of mix gas and fluidized state in fluidized bed reactor.
In a pennaceous feather, the barbs grow helically around the tubular feather germ and fuse on one side to form the rachis.Simultaneously, new barb ridges form on the other side of the tube.
