Point \Point\, n. 1. (Med.) A pointed piece of quill or bone covered at one end with vaccine matter; -- called also {vaccine point}. 2. One of the raised dots used in certain systems of printing and writing for the blind. The first practical system was that devised by Louis Braille in 1829, and still used in Europe (see {Braille}). Two modifications of this are current in the United States: {New York point} founded on three bases of equidistant points arranged in two lines (viz., : :: :::), and a later improvement, {American Braille}, embodying the Braille base (:::) and the New-York-point principle of using the characters of few points for the commonest letters. 3. In technical senses: (a) In various games, a position of a certain player, or, by extension, the player himself; as: (1) (Lacrosse & Ice Hockey) The position of the player of each side who stands a short distance in front of the goal keeper; also, the player himself. (2) (Baseball) (pl.) The position of the pitcher and catcher. (b) (Hunting) A spot to which a straight run is made; hence, a straight run from point to point; a cross-country run. [Colloq. Oxf. E. D.] (c) (Falconry) The perpendicular rising of a hawk over the place where its prey has gone into cover. (d) Act of pointing, as of the foot downward in certain dance positions. | |

2. The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.; as, a vacuum of 26 inches of mercury, or 13 pounds per square inch. {Vacuum brake}, a kind of continuous brake operated by exhausting the air from some appliance under each car, and so causing the pressure of the atmosphere to apply the brakes. {Vacuum pan} (Technol.), a kind of large closed metallic retort used in sugar making for boiling down sirup. It is so connected with an exhausting apparatus that a partial vacuum is formed within. This allows the evaporation and concentration to take place at a lower atmospheric pressure and hence also at a lower temperature, which largely obviates the danger of burning the sugar, and shortens the process. {Vacuum pump}. Same as {Pulsometer}, 1. {Vacuum tube} (Phys.), a glass tube provided with platinum electrodes and exhausted, for the passage of the electrical discharge; a Geissler tube. | |

Vasodilator \Vas`o*di*lat"or\, a.[L. vas a vessel + dilator.] (Physiol.) Causing dilation or relaxation of the blood vessels; as, the vasodilator nerves, stimulation of which causes dilation of the blood vessels to which they go.

d8Vis \[d8]Vis\, n. 1. Force; power. 2. (Law) (a) Physical force. (b) Moral power. {Principle of vis viva} (Mech.), the principle that the difference between the aggregate work of the accelerating forces of a system and that of the retarding forces is equal to one half the vis viva accumulated or lost in the system while the work is being done. {Vis impressa} [L.] (Mech.), force exerted, as in moving a body, or changing the direction of its motion; impressed force. {Vis inerti[91]}. [L.] (a) The resistance of matter, as when a body at rest is set in motion, or a body in motion is brought to rest, or has its motion changed, either in direction or in velocity. (b) Inertness; inactivity. Note: Vis interti[91] and inertia are not strictly synonymous. The former implies the resistance itself which is given, while the latter implies merely the property by which it is given. {Vis mortua} [L.] (Mech.), dead force; force doing no active work, but only producing pressure. {Vis vit[91]}, or {Vis vitalis} [L.] (Physiol.), vital force. {Vis viva} [L.] (Mech.), living force; the force of a body moving against resistance, or doing work, in distinction from vis mortua, or dead force; the kinetic energy of a moving body; the capacity of a moving body to do work by reason of its being in motion. See {Kinetic energy}, in the Note under {Energy}. The term vis viva is not usually understood to include that part of the kinetic energy of the body which is due to the vibrations of its molecules. | |

Vision \Vi"sion\, n. [OE. visioun, F. vision, fr. L. visio, from videre, visum, to see: akin to Gr. [?] to see, [?] I know, and E. wit. See {Wit}, v., and cf. {Advice}, {Clairvoyant}, {Envy}, {Evident}, {Provide}, {Revise}, {Survey}, {View}, {Visage}, {Visit}.] 1. The act of seeing external objects; actual sight. Faith here is turned into vision there. --Hammond. 2. (Physiol.) The faculty of seeing; sight; one of the five senses, by which colors and the physical qualities of external objects are appreciated as a result of the stimulating action of light on the sensitive retina, an expansion of the optic nerve. 3. That which is seen; an object of sight. --Shak. 4. Especially, that which is seen otherwise than by the ordinary sight, or the rational eye; a supernatural, prophetic, or imaginary sight; an apparition; a phantom; a specter; as, the visions of Isaiah. The baseless fabric of this vision. --Shak. No dreams, but visions strange. --Sir P. Sidney. 5. Hence, something unreal or imaginary; a creation of fancy. --Locke. {Arc of vision} (Astron.), the arc which measures the least distance from the sun at which, when the sun is below the horizon, a star or planet emerging from his rays becomes visible. {Beatific vision} (Theol.), the immediate sight of God in heaven. {Direct vision} (Opt.), vision when the image of the object falls directly on the yellow spot (see under {Yellow}); also, vision by means of rays which are not deviated from their original direction. {Field of vision}, field of view. See under {Field}. {Indirect vision} (Opt.), vision when the rays of light from an object fall upon the peripheral parts of the retina. {Reflected vision}, [or] {Refracted vision}, vision by rays reflected from mirrors, or refracted by lenses or prisms, respectively. {Vision purple}. (Physiol.) See {Visual purple}, under {Visual}. | |

Visual \Vis"u*al\, a. [L. visualis, from visus a seeing, sight: cf. F. visuel. See {Vision}.] 1. Of or pertaining to sight; used in sight; serving as the instrument of seeing; as, the visual nerve. The air, Nowhere so clear, sharpened his visual ray. --Milton. 2. That can be seen; visible. [R.] {Visual angle}. (Opt.) See under {Angle}. {Visual cone} (Persp.), a cone whose vertex is at the point of sight, or the eye. {Visual plane}, any plane passing through the point of sight. {Visual point}, the point at which the visual rays unite; the position of the eye. {Visual purple} (Physiol.), a photochemical substance, of a purplish red color, contained in the retina of human eyes and in the eyes of most animals. It is quickly bleached by light, passing through the colors, red, orange, and yellow, and then disappearing. Also called {rhodopsin}, and {vision purple}. See {Optography}. {Visual ray}, a line from the eye, or point of sight. {Visual white} (Physiol.), the final product in the action of light on visual purple. It is reconverted into visual purple by the regenerating action of the choroidal epithelium. {Visual yellow} (Physiol.), a product intermediate between visual purple and visual white, formed in the photochemical action of light on visual purple. | |

VAX MIPS power normally attributed to a {Digital Equipment Corporation} {VAX} 11/780. Future VAX systems were rated according to this scale (e.g. VAX 8350's being 2.7 VUPs per CPU). A {MicroVAX} II is normally associated with 0.9 VUPs and at a later time the MicroVUP was coined to rate VAX {workstations}. The use of the VUP by Digital Equipment Corporation has been replaced with more standard benchmarks ({SPECint} and {SPECfp}) in the {DEC Alpha} processor systems. (1996-08-22) |
