Compact striations, broken rough striations, and rough structures formed in succession from the notch tip to the unfractured region to dissipate a large amount of the impact energy.
When the compressed profile is extracted from a land impression by averaging multiple surface profiles measured perpendicular to the striation direction, invalid areas may be encountered that are weakly striated and do not contain valid striation information.
Deleuze and Guattari explain that, while capitalism has taken striation to "an unequaled point of perfection, circulating capital necessarily recreated, reconstituted, a sort of smooth space in which the destiny of human beings is recast" (492).
This motion results in striation formation between the colored populations with a progressive decrease in the striation thickness along the extruder channel.
However, since stretching has a continuous monotonic spectrum (and so do striation thicknesses), a more realistic criterion is to define x as the fraction of all stretching values that exceed a particular value, which assures that a certain fraction of striations have thicknesses under a certain desired value.
The striation thickness concept was first introduced by Mohr et al.
As the change in the volume of the layer was equal to the volume of material flowing through the same striation in the capillary, the average velocity, V, of the material could be determined by:
In the western striation, history becomes an image, its floor to ceiling annals fitted and transformed into a spatial illusion, aro und which people circulate without having any reason to enter.
First a standard k-[Epsilon] model was used (4) but the results were not satisfactory, the computed striation thickness was much too small.
Two separate kimberlite indicator mineral trains were broadly defined, with direction confirmed by glacial striation.
