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 ...

A research team has developed an innovative manufacturing process for permanent magnets that overcomes the limitations of ...

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 ...

Determining the slip lengths for liquids flowing close to smooth walls is challenging. The reason lies in the fact that the scales that must be addressed range between a few and hundreds of nanometres ...

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 ...

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 ...

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 ...
