Increasing the inter-pillar gap size from 1 to 6 μm for surfaces with small pillar sizes of 1 and 2 μm resulted in decreased proliferation and in more elongated cells with long pseudopodial protrusions.
When fibroblasts are plated onto closely spaced small pillars (5 μm), cells form adhesions on the top and side of the pillars, simulating a 3D environment.
The company has already begun making its microprocessors using a new 3-D transistor design, called a Finfet (for fin field-effect transistor), which is based around a remarkably small pillar, or fin, of silicon that rises above the surface of the chip.
He describes it as 'a small solid erection in the form of a wagon roof, over what is supposed to be the patriarch's grave, with a small pillar or altar at each of its extremities, sometimes called the tombs of Ephraim and Manasseh, and the middle of an enclosure without a covering.
We report on the practical limitations of the current state-of-the-art in micro-fabrication technology to produce the small pillar sizes that are needed to obtain high efficiency pillar array columns.
Lastly, pinnacles are small pillar-like seamounts.
Based on the engineering project on a small coal pillar of 12,521 working face roadway in Xieqiao Coalmine, data regarding surface displacements of the coal pillar, deep displacements and mining stress have been collected and analyzed.
In a more realistic case, in a scapula with a small horizontal pillar of 5 mm (average = 12 mm), the notch angle will decrease by 6° for 2 mm of lateralization and by 20° for 2 mm of inferior overlap.
However, the individual shear banding events are strongly size-dependent, i.e. in larger pillars the deformation is controlled by nucleation of shear bands, but in smaller pillars it becomes propagation-controlled.
In the regime of shear deformation, the extrinsic size dependence is displayed in that the deformation was controlled by shear bands nucleation in larger pillars while controlled by shear bands propagation in smaller pillars.
