(1st p612 - 2nd p874 - Bonner p202) Thompson considers the three types of horn that occur in quadrupeds: the keratin horn of the rhinoceros; the paired horns of sheep or goats; and the bony antlers of deer.
It is discussed the design study of several types of horns, simulated on the CST software.
The study focuses on the origins of keratin proteins, the building blocks of mammalian fingernails, claws, and some types of horns.
Two types of horns are evident in cattle - fixed horns attached to the skull and a variation called scurs, which refers to small loosely attached horns.
In order to focus on these genes, we collapsed the data from array elements into non-redundant sequences (contigs and singletons), and then filtered the non-redundant sequences for those that were both statistically differentially expressed and showed at least two-fold changes in either head horns, prothoracic horn or both types of horns.
We find that, largely independent of the PC parameters, or of the length and width of the tapered region, the same type of concave, horn-shaped tapering profile is optimal for coupling from the waveguide into free space, and significantly out-performs the widely used linear taper.
An analytical method for designing five-element acoustic horns with the desirable matching properties is introduced, and five novel types of such horns, most suitable for practical applications, are proposed.
As individuals have been followed from birth, recording their identity allowed us to determine the age and horn type of every individual in the sample.
Her performance is less a matter of words than of small physical details: tilts of her lovely head, topped, here, with a pair of Minoan-bull type horns; gleams of the eyes, plunging to great, green depths; and, of course, adjustments of the famous Duchampian cheekbones, whose angularity was greatly enhanced for the occasion by the Disney makeup people.
