The crossing of two species with the production of fertile offspring, which then usually cross back to one of the parents. This produces a diffusion(introgression) of genes from one species to the other, giving a range of phenotypes of both parental types and a series of hybrids between them.  2, fiche 2, Anglais, - introgressive%20hybridization

[A factor] represented by a term in the van Deemter equation. It is the contribution to plate height that is due to molecules traveling along paths through the column and it depends on the particle size and geometry of the packing.  2, fiche 3, Anglais, - eddy%20diffusion%20term

Record number: 3, Textual support number: 1 CONT

Eddy diffusion broadens the band when passing through the column and detected in the chromatography. This is due to the molecules of the sample traveling through the column along many different paths of different lengths. The shortest path is the front of the band and the longest path is located in the back of the band. This can be corrected if the band is broad and the column support is of small size and uniform. This effect may be described by the van Deemter equation. H=A+(B/u) +Cu. Where M is the flow rate, A is the eddy diffusion term, B/u is the longitudinal diffusion term and Cu is the mass-transfer rate term. The eddy diffusion is independent of the flow-rate and only is concerned by how the column was packed.  1, fiche 3, Anglais, - eddy%20diffusion%20term

The phenomenon which causes solutes to concentrate at the filter's membrane surface forming a gel layer. The thickness of this gel layer will increase until its hydraulic resistance to solvent transport reduces the flux to an equilibrium value such that the convective transport of solutes on the surface equals the back diffusion from the surface. In single-pass operation the concentration of sulutes is low, so concentration polarization does not limit flux.  1, fiche 4, Anglais, - concentration%20polarization
