(n.) A small constellation north of Aquila; the Arrow.
(n.) The keystone of an arch.
(n.) The distance from a point in a curve to the chord; also, the versed sine of an arc; -- so called from its resemblance to an arrow resting on the bow and string.
(n.) The larger of the two otoliths, or ear bones, found in most fishes.
(n.) A genus of transparent, free-swimming marine worms having lateral and caudal fins, and capable of swimming rapidly. It is the type of the class Chaetognatha.
Example Sentences:
(1) In addition, we report a new type of photoreceptive cell in mesopelagic Sagitta zetesios, in which two receptoral processes emerge from single cells, in contrast to one in all the other species of Sagitta.
(2) The presumed photoreceptive region of the arrow-worms of the species Sagitta crassa and Spadella schizoptera consists of perforated lamellae which are unique as the photoreceptive structure.
(3) The sagittae of tire- and barrel-form toric surfaces differ off the principal meridians, as is shown by a numerical example.
(4) The exact equation for sagitta of spherical surfaces is generalized to toric surfaces which include spherical and cylindrical surfaces as special cases.
(5) The experience gathered in the correction of sagittal mandibular over- and under-development allows to make the following conclusions:--In the choice of osteotomy it is necessary that careful consideration be given not only to the proportions of the body and ramus of the mandible, but also to the angular interrelationships of mandibular bones.--Osteotomies in the body of the mandible are indicated especially in those cases where it is only necessary for parallel shifts to be made in the sagittal plane.--Osteotomies performed in the region of the angle of the mandible and the ramus of the mandible (Obwegeser-Dal Pont) enable both longitudinal compensation or adjustment in the sagitta.
(6) Generalized equations are derived for sagitta and lens thickness for surfaces of any form.
(7) The value of the second fundamental form is approximately double the sagitta.
(8) The gerbils' fleas are more abundant on D. sagitta than on the other species.
(9) Under study was the histological structure of the adrenal of the gopher Spermophilopsis leptodactylus L., jerboa Dipus sagitta Pall.
(10) A survey of the eye structure in 10 species of Sagitta (phylum Chaetognatha) which differ in habitat was carried out: 5 epipelagic, 4 mesopelagic and 1 bathypelagic species.
(11) A general routine exists for estimating dioptric power from any number of measurements of sagitta, lens thickness, meridional curvature or power, and prismatic effect.
(12) A method published elsewhere for estimating dioptric power from meridional measurements is generalized here to allow for measurements of sagitta, lens thickness, and prismatic effect as well.
(13) The histology of the Chaetognath's trunk is largely based upon works of Hertwig (1880) and Burfield (1927) and is revised here essentially on ultrastructural basis, in a study on Sagitta setosa.
(14) The existence of a visual pigment in this region was demonstrated by a histofluorescent technique using Spadella schizoptera, whose presumed photoreceptive region was much larger than in Sagitta crassa.
(15) 2) From the hemodynamic change, the progression of rapid increase of cerebral blood volume with increase of blood volume in the superior sagitta sinus during cerebral vasoparesis under intracranial hypertension is presumed.
(16) In four species, the sagitta exhibited a multifluted anterior part and a tapered posterior part; in Corydoras aeneus, however, the fluted part was absent, and a vertical component extended dorsally to terminate near the opening of the transverse canal.
Sagittarius
Definition:
(n.) The ninth of the twelve signs of the zodiac, which the sun enters about November 22, marked thus [/] in almanacs; the Archer.
(n.) A zodiacal constellation, represented on maps and globes as a centaur shooting an arrow.
Example Sentences:
(1) Chromosome studies of 1 species of Cariamidae and Sagittarius show great karyological differences and tend to dispel the suggestion of a possible relationship between the families.
(2) Burrows’ colleague Cecil Lewis, a former fighter pilot and author of Sagittarius Rising , gave a vivid account of its impact.
(3) Cecil Lewis, the first world war fighter pilot who wrote Sagittarius Rising, was its first organiser of programmes.
(4) It's a very specific late 60s that he evokes on his debut album, Cabinet of Curiosities: the ornate, lushly orchestrated, psych-inflected "soft rock" or "baroque pop" of British groups such as Nirvana and the Zombies, and American bands such as the Millennium and Sagittarius.
