Sentence examples for a significant diffusion of from inspiring English sources

We can conclude that our data are not consistent with the hypothesis that there was a significant diffusion of genes into Western Europe driven by the acquisition of agriculture during the Neolithic age and support the notion that knowledge can spread faster than the genes of its discoverers.

Since we were unable to detect AsA-totAsA in the control incubation medium (results not shown), it is unlikely that a significant diffusion of AsA or DHA from the tissue occurred under our incubation conditions.

In addition, taking advantage of the excellent diffusion barrier properties of Si3N4 [17], well-defined Ge-NCs are expected to be formed in the top nitride layer without any significant diffusion of Ge toward Si/tunnel oxide interface and/or to the surface of control layer by suitably varying the implantation parameters and annealing condition.

Therefore, a significant diffusion intensification of cobalt atoms under cyclic γ-ε-γ transformations is associated with the effect of two independent mechanisms - an athermal and a thermally activated one.

Braginsky and Le Mouël (1993) and Jault and Le Mouël (1994) have examined the effect of such a thin layer in which the flow is driven by a dynamics distinct from that within the underlying volume of the core and claimed that a significant diffusion occurs in response to fluctuations of horizontal flow therein.
