Hence, the frequency of mobile communications between regions may be reflective of their economic ties.
This flow behaviour was well described by the model through the parameters n and fm, that is, in terms of the degree of mixing of water in soil and the ratio between mobile regions and the maximum amount of water in a monolith when freely drained.
I would like to sum up by saying that the 'lifelong learning' programme will help improve the EU's educational and training programmes, make people more mobile, support partnerships and cooperative efforts between regions, structure the sharing of best practice and encourage the learning of foreign languages.
It is also demonstrated that as the contaminant mass transfer rate coefficient between the mobile and immobile regions increases, the contaminant concentration gradient between the two regions reverses at earlier pore volumes.
The mass transfer coefficient, ω, characterizes the level of solute exchange between mobile and immobile regions.
The mass-transfer coefficient, for solute transport between mobile and immobile regions, was considered as a model calibration factor.
Several alternative transport processes are considered: advection, advection dispersion and/or mass-transfer between mobile and immobile regions.
When coupling the 2-site sorption model with the 2-region transport model, except of the kinetic sorption parameters, the soil column datasets enable us to estimate the mass-transfer coefficients associated with solute diffusion between mobile and immobile regions.
The concept of first-order mass transfer between mobile and immobile regions, which mathematically simplifies the concept of Fickian diffusion in stagnant areas, has often been used to describe physical nonequilibrium transport of solutes into natural porous media.
The contaminant transfer between the mobile and immobile regions takes place by diffusive mass transfer.
