Mechanical actions like vortexing, shaking or centrifuging are used to enhance molecular dispersal and diffusion to the cellular boundaries and to provide forces that can be helpful in disrupting cell–cell attachments. Conventional tissue dissociation can require hours of time and numerous instruments ...
This situation would resemble the diffusion distances in the schematised conifer and early angiosperm leaf morphologies (cf. Fig. 1e). The second result of this example is that a change in pore radius has the largest effect on the flux of the substance that diffuses over the shortest radial...
of the pore resistance27. As smaller stomata reduce the diffusion distance across the stomatal pore and limit the resistance of the ‘end correction’ term in equation (1), evolution towards highergsmaxwas necessarily linked to a reduction in stomatal size combined with an increase in stomatal de...
Greater patient and public involve- ment at later stages could promote the adoption and diffusion of innovations [24]. The amendment under discussion has made it possible to use patient insights for the first time. Although the categorization of medicines is governed by the Ministry of Health, a...
Facilitated transport membranes (FTMs) work on a different principle compared to conventional membranes. Current state-of-the-art materials are based on the solution-diffusion transport mechanism where the different species dissolve in the material, diffuse through and then desorb on the other side. ...
