Grain rotation, grain boundary sliding or migration, dislocation motion and intergranular activities are observed in the deformation process.
A Mann-Whitney non-parametric test and a Wilcoxon signed-rank test showed that there was no statistically significant difference in the median rotations or proximal/distal migrations at any follow-up interval (p > 0.05).
None of the cups showed evidence of migration, angular rotation or radiolucent lines: all of them were thus considered well fixed and stable with bone-ingrowth.
Combining all 4 RSA parameters (translation vector, rotation vector, y-translation, and y-rotation), detectable stem migration (translation or rotation, or both) was found in 7 patients of 39 as a sign of unstable stems at 24 months.
NI inaccurately portrays mutation, drift, or migration.
These were used to identify rotation and migration of the screws in the plate holes and displacement of the plate.
The statistically significant differences in rotation and migration occurring after 3 months were very small, and they were below the limits for statistically significant movement.
In addition with selective host rotation or elimination, the effects of reducing vector population density, particularly over periods of vector migration between hosts, on virus prevalence and virulence would be enhanced.
No rotation or subs were allowed.
