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 ...

The product distribution of isomers from the deuterium exchange of neopentane over palladium supported on silica-alumina particles is influenced by the competition among three rate processes: ...

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 ...

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 ...

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

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 ...

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 ...

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. 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 ...
