This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

Molecular diffusion controls the dynamics of chemical reactions and film growth processes 4 and is of fundamental importance to the emerging fields of organic electronics and molecular nanotechnology ...

Established surface-science tools could help industrial scientists to fast-track the evaluation of advanced materials for energy-storage applications Surface physics: the OCI team has integrated a UHV ...

Numerical methods have been applied to the problem of the diffusion of CO and O 2 through the red blood corpuscle membrane, accompanied by diffusion and chemical reaction of these substances in the ...

BMC Clin Pharmacol. 2010;10:1-27. One can use this value of PS to estimate the "equivalent" thickness of the rat blood-adipose diffusion limiting barrier. The permeability is equal to: where D W is ...

This is a preview. Log in through your library . Abstract (1) The mathematical derivation of a simple model of seed dispersal, based on the two processes of diffusion and predation, is given. It uses ...

Inhalation and exhalation is the same as breathing or ventilation and is a physical process which moves air into and out of your lungs. Respiration is not the same as breathing, and is a chemical ...

BMC Clin Pharmacol. 2010;10:1-27. It is assumed that the tissue consists of N capillaries/cm 3, all with exactly the same geometry, blood flow, permeability, etc. It is also assumed that the relation ...
