"Annular pancreas Annular pancreas is a rare condition in which the second part of the duodenum is surrounded by a ring of pancreatic tissue continuous with the head of the pancreas. This portion of the pancreas can constrict the duodenum and block or impair the flow of food to the rest of the intestines. It is estimated to occur in 1 out of 12,000 to 15,000 newborns. The ambiguity arises from the fact that not all cases are symptomatic. Early signs of abnormality include polyhydramnios (an excess of amniotic fluid), low birth weight, and feeding intolerance immediately after birth, in"
"Annulus (mathematics) In mathematics, an annulus (the Latin word for ""little ring"" is ""anulus""/""annulus"", with plural ""anuli""/""annuli"") is a ring-shaped object, a region bounded by two concentric circles. The adjectival form is annular (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder and the punctured plane. Informally, it has the shape of a hardware washer. The area of an annulus is the difference in the areas of the larger circle of radius and the smaller one of radius : The area of an annulus is determined by the length of the longest line segment"

"Mandorla A mandorla is an aureola, or frame, usually in the shape of a vesica piscis, which surrounds the figures of Christ and the Virgin Mary in traditional Christian art. It is distinguished from a halo in that it encircles the entire body, and not just the head. It is commonly used to frame the figure of Christ in Majesty in early medieval and Romanesque art, as well as Byzantine art of the same periods. The term ""mandorla"", from the Italian language name for the ""almond"" nut, refers to the usual shape. Sometimes however, especially in earlier depictions, the mandorla"
"the field is C with the usual norm, formula_15 is already singly periodic; modding out by q's integral powers you are modding out formula_16 by formula_17, which is a torus. In other words, we have an annulus, and we glue inner and outer edges. But the annulus does not correspond to the circle minus a point: the annulus is the set of complex numbers between two consecutive powers of q; say all complex numbers with magnitude between 1 and q. That gives us two circles, i.e., the inner and outer edges of an annulus. The image of the torus given"
"Mandrel A mandrel (; also mandril or arbor) is one of the following: An example of one type of mandrel is a shaped bar of metal inserted in, or next to, an item to be machined or bent in a certain pattern, e.g. in tube drawing. Exhaust pipes for automobiles are frequently bent using a mandrel during manufacture. The mandrel allows the exhaust pipes to be bent into smooth curves without undesirable creasing, kinking, or collapsing. Molten glass may be shaped in this way as well. Another example of this type of mandrel is found in jewelry manufacturing, where ring"
"Angular diameter The angular diameter, angular size, apparent diameter, or apparent size is an angular measurement describing how large a sphere or circle appears from a given point of view. In the vision sciences, it is called the visual angle, and in optics, it is the angular aperture (of a lens). The angular diameter can alternatively be thought of as the angle through which an eye or camera must rotate to look from one side of an apparent circle to the opposite side. Angular radius equals half the angular diameter. The angular diameter of a circle whose plane is perpendicular"
"Catenary In physics and geometry, a catenary (, ) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends. The catenary curve has a U-like shape, superficially similar in appearance to a parabolic arch, but it is not a parabola. The curve appears in the design of certain types of arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette, or, particularly in the materials sciences, funicular. Mathematically, the catenary"

"denticle. The lip is thickened and corrugated within. The form is just like ""Clanculus cruciatus"" . The shell consists of 6 to 7 rather rounded whorls, the body whorl not angulated to speak of, and with a rather convex base. The spiral cinguli gradually increase in number, so that on the penultimate whorl there are about 11, on the body whorl about 40 of them. On the upper whorls they are distinctly granulose, on the last almost entirely smooth. The umbilicus is pretty narrow, its margin dentate. The columella is very oblique, not free above, with a small but prominent"
"The high, narrow shell has a biconically fusiform shape. It is scalar, carinated, with spiral threads, thin, white. The axial sculpture on the shell is scored with coarse irregular sinuous lines of growth ; but there is no trace of any other longitudinal markings. The spiral sculpture shows above the middle of each whorl is a strong carination only slightly projecting, but marked by the angulation of the whorl and by the prominence of the thread on its crest. On the body whorl there is a tendency to a second carination, which runs into the aperture just below the junction"

Across the body there is no pad, but the shell is eroded, which looks like a thin callus. The outer lip is thin, not descending. The columellar lip is slightly patulous, bending flatly over the umbilicus, and then advancing in a straight line to the point of the columella, where it is slightly angulated just where the beaded umbilical spiral ends. The umbilicus is funnel-shaped, rather open, but a good deal contracted within, sharply scored"

The base of the shell is nearly flat, impressed near the centre, which is more or less filled by a thick callus, which is white, with radiating striae on its external margin, granular near the columellar margin, and is ornamented there, with 4 or 5 granules. The base of the shell round the callus, is likewise provided with radiating grooves. The aperture is subtriangularly rounded, very oblique. The outer margin is thin, slightly thickened interiorly. The columellar margin is thickened, its upper end pressed to the body whorl, with a thin layer connecting the margins. The yellow operculum is"
"I-bundle In mathematics, an I-bundle is a fiber bundle whose fiber is an interval and whose base is a manifold. Any kind of interval, open, closed, semi-open, semi-closed, open-bounded, compact, even rays, can be the fiber. Two simple examples of I-bundles are the annulus and the Möbius band, the only two possible I-bundles over the circle formula_1. The annulus is a trivial or untwisted bundle because it corresponds to the Cartesian product formula_2, and the Möbius band is a non-trivial or twisted bundle. Both bundles are 2-manifolds, but the annulus is an orientable manifold while the Möbius band is a"

"Annulus (well) The annulus of an oil well or water well is any void between any piping, tubing or casing and the piping, tubing, or casing immediately surrounding it. It is named after the corresponding geometric concept. The presence of an annulus gives the ability to circulate fluid in the well, provided that excess drill cuttings have not accumulated in the annulus, preventing fluid movement and possibly sticking the pipe in the borehole. For a new well in the process of being drilled, this would be the void between the drill string and the formation being drilled. An easy way"

"all with narrower interspaces. The axial sculpture comprises first, fine elevated lamellae covering the whole shell evenly and giving it a slightly spongy aspect; secondly, on the body whorl, about ten elevations, not perceptibly continuous over the top of the shell but prominent, over the periphery and reflected backward like incomplete varices. The outer whorl is coiled over these so that the whorl inside only touches the outer one by these prominences. They are not continuous over the base, but within the ample umbilicus are two rows of small prominences corresponding in number to those on the periphery. The circular"
"Cannula A cannula (; from Latin """"little reed""""; plural ""cannulae"" or ""cannulas"") is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of data. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. It is also called an intravenous (IV) cannula. Its size mainly ranges from 14 to 24 gauge. Different-sized cannulas have different colours as coded. Decannulation is the permanent removal of a cannula"

The periphery of the body whorl is rendered decidedly angulated by the spiral cord. The base of the shell is short, well rounded, marked on the posterior fourth by six, narrow, flattened, spiral bands and between these and the umbilical chink by seven additional bands of about double the width of the former. The umbilicus is covered with a white callus. The aperture is subcircular and very"

The body whorl has spiral sculpture only. The uppermost spiral cord on the shoulder angle is faintly nodulous on the earlier part of the body-whorl as a last suggestion of the previous axial sculpture. Weak growth-lines cover most of the shell, being rather more prominent on the smooth shoulder.The aperture is subquadrate, strongly channelled below and with a light sinus above. The columella is vertical, bent to the left below. The outer"

The shell contains 8 whorls, making allowance for the eroded apex. They have a long, sloping, slightly concave shoulder, a blunt angulation about two-thirds down, and below this are nearly cylindrical. The fifth whorl enlarges somewhat disproportionately. And the last whorl is swollen, with a sharper angulation than the rest. The base is convexly conical, and is produced into a lop-sided, centrally situated, small-pointed snout. The suture is small"
"is continuously changing. In common speech, ""oval"" means a shape rather like an egg or an ellipse, which may be two-dimensional or three-dimensional. It also often refers to a figure that resembles two semicircles joined by a rectangle, like a cricket infield, speed skating rink or an athletics track. However, this is more correctly called a stadium. Sometimes, it can even refer to any rectangle with rounded corners.
