The narrow and deep foveal depression with a spherical pit may reduce light scattering [48] and facilitate image magnification [24], image fixation and exaggeration of small movements [49], and directional focus [50].
Different artificial spherical pits were fabricated on the surface of joints to conveniently simulate the prior corrosion.
For PS-b-P4VP with cylindrical structure in bulk, as annealing time progressed, the surface morphology underwent structural transitions from featureless topography to hybrid morphology of cylindrical and spherical pits, to cylinders, to nanoscale depressions, back to cylinders again.
By assuming that the pit shape has a spherical shape the pit growth rate can be obtained by deriving Eq. (5) with respect to time: frac{dp}{dt} = 0.0116alpha i_{corr} left( t right) (7).
Polonium and beryllium were the key ingredients of the 'urchin' detonator at the center of the bomb's spherical plutonium pit.
One is the classic clathrin-coated pit, which forms a spherical clathrin cage structure with an enclosed membrane, leading to internalization even when actin polymerization is blocked (Ehrlich et al. 2004; Loerke et al. 2009).
One garden, designed by Adam Hoppe, a landscape architect, is centered around a curving stone patio bordered with annuals and flowers and features a spherical stone fountain set before three hornbeam trees and a contemporary fire pit.
Global pit latrine coverage.
In contrast to that in cell lumen, the Cu NPs in pits were assembled into small spherical agglomerates with diameter from 1 to 2.5 μm.
The crust corresponds to the skin, the iron core (although spherical rather than pointed) to the pit, and the rocky mantle, which constitutes eighty-four per cent of the volume of the planet, to the flesh of the fruit.
