The tooth batteries, however, differed from those of the hadrosaurs in forming long, vertical slicing surfaces as upper and lower batteries met, operating much like self-sharpening shears.
They occluded directly to form distinct chisel-like cutting edges with a self-sharpening mechanism maintained by hard enamel on the outer side of the upper teeth and the inner side of the lower.
In its mouth was a set of high grooved, self-sharpening cheek teeth adapted for grinding plant matter; in its horny beak were several incisor-like teeth used to nip off vegetation.
Since the time of our last common ancestry with chimpanzees, millions of years ago, it may have contributed to the de-weaponization of maleness, including the elimination of self-sharpening male canine teeth, the reduction in male body size relative to females, the elimination of infanticide by ascendant alpha males, and the origin of paternal investment in their offspring.
In this article, the self-sharpening phenomenon arisen by ion-exchange membranes is studied.
The coating design, inspired from sea urchin and shark teeth architectures, delivers serrated cutting edges and self-sharpening.
The degenerate parabolic Generalized Porous Medium Equation (GPME) poses numerical challenges due to self-sharpening and its sharp corner solutions.
We like the smooth, quick-drying, non-bleeding Uni-ball Jetstream pen, or the self-sharpening, remarkably consistent Uni-ball Kuru Toga pencil.
Based on these microstructure observation and hardness data, the abrasive behavior and microstructural mechanism of self-sharpening of the chiton tooth were discussed in the paper.
This paper discusses bio-inspired ideas for chip transport and tool cleaning, abrasive wear resistance, self-sharpening, breaking air barriers, cooling, and new process environments.
The self-sharpening was attributed to the combined effect of the hardness and the texture orientation of the microstructure units in Regions I and II.
