"Convexity" Quotes from Famous Books
 ... room was not finished above the second roof level, and there is no doubt that two stories above the ground were the maximum height of the western rooms, excluding the parapet. The eastern wall presents a marked double convexity while the western wall is comparatively straight in a horizontal line, but markedly concave vertically above the first roof level. Below this level it is straight. The floor beams were from 3 to 6 inches ...

... slightly less than that of the glass to be ground, and are, say, half an inch thick. These discs are turned convex or concave on one face according as they are to be employed in the production of concave or convex glass surfaces. The proper degree of convexity or concavity may be approximated to by turning with ordinary turning tools, using a circular arc cut from zinc or glass (as will be described) as a "template" or pattern. This also is a ...

... that, from their comparatively slender and slightly curved form, so unlike the digitals of its cogener the Ichthyosaurus, could have belonged evidently to no other reptile. I observed, too, in the slightly curved articulations of not a few of the vertebrae, the gentle convexity in the concave centre, which, if not peculiar to the Plesiosaurus, is at least held to distinguish it from most of its contemporaries. Among the various nondescript organisms of the shale, I laid open a smooth angular bone, hollowed something like a grocer's scoop; a three-pronged caltrop-looking ...

... whilst the edges are shot, because any inequality would be multiplied by the number of pieces jointed. A better method is to alternate the boards, face side up, then face side down, whilst shooting the edges; this will prevent convexity or concavity on the face of the jointed board, because any slight error in the angle ...

... more or less furrowed behind in the middle—in other words, it forms a sort of trough; and the deeper the trough the student learns to form at will, the better, for there are times in actual singing and speaking when this must be as deep as possible. It is clear that in this way the central convexity above, formed by the hard palate, forms with the corresponding concavity in the tongue a sort of trumpet-shaped organ admirably adapted for the ...

... beating up against the wind for Portsmouth or Southampton. Away on the right was the long line of white foam which marked the Winner Sands. The tide was in and the great mudbanks had disappeared, save that here and there their dun-coloured convexity rose above the surface like the back of a sleeping leviathan. Overhead a great flock of wild geese were flapping their way southward, like a broad arrow against the sky. It was an exhilarating, bracing scene, and accorded ...
— The Firm of Girdlestone • Arthur Conan Doyle
... observe, however, that the convexity is to be very slight, and that the shaft is not to bulge in the centre, but to taper from the root in a curved line; the peculiar character of the curve you will discern better by exaggerating, in a diagram, the ...

... incomplete, for example in greenstick fractures, which occur only in young persons—usually below the age of twelve—while the bones are still soft and flexible. They result from forcible bending of the bone, the osseous tissue on the convexity of the curve giving way, while that on the concavity is compressed. The clavicle and the bones of the forearm are those most frequently the seat of greenstick fracture (Fig. 41). Fissures occur on the flat bones of the skull, the pelvic bones, and the scapula; or in ...

... wing, mounts up, To the convexity of bending Heaven, And writes each name, who fought with us this day, In fairest character, amidst the stars. The world shall read it, and still talk of us, Who, far out-number'd, twice drove back the foe, With carnage horrid, murm'ring to their ships. ...

... bend of the joints of every limb the reliefs are converted into a hollow, and likewise every hollow of the innermost bends becomes a convexity when the limb is straightened to the utmost. And in this very great mistakes are often made by those who have insufficient knowledge and trust to their own invention and do not have recourse to the imitation of nature; ...

... altered; for the situation would have been terrible if it failed in its aim, and being carried beyond the disc should be launched into interplanetary space. At that moment, the moon, instead of appearing flat like a disc, showed its convexity. If the sun's rays had struck it obliquely, the shadow thrown would have brought out the high mountains, which would have been clearly detached. The eye might have gazed into the crater's gaping abysses, and followed the capricious fissures which ...

... toward both banks, more rapidly with approach to the banks or with shallowing of the depth, very rapidly close to the banks, and was very small at the edges, possibly zero. The figure of the curve was found to be determined by the figure of the bed, a convexity in the bed producing a concavity in the curve and vice versa, and more markedly in shallow than in deep water. Curves on the same transversal, at the same site, and with similar conditions, but differing in general velocity, were nearly parallel ...

... lies in the true pelvis and forms a loop, the two limbs of which are superior and inferior while the convexity reaches across to the right side of the pelvis. In the foetus this loop occupies the right iliac fossa, but, as the caecum descends and enlarges and the pelvis widens, it is usually driven out of this region. The distal end of the loop turns sharply ...
