| speed | 1. To go; to fare. "To warn him now he is too farre sped." (Remedy of Love) 2. To experience in going; to have any condition, good or ill; to fare. "Ships heretofore in seas lke fishes sped; The mightiest still upon the smallest fed." (Waller) 3. To fare well; to have success; to prosper. "Save London, and send true lawyers their meed! For whoso wants money with them shall not speed!" (Lydgate) "I told ye then he should prevail, and speed On his bad errand." (Milton) 4. To make haste; to move with celerity. "I have speeded hither with the very extremest inch of possibility." (Shak) 5. To be expedient. Origin: AS. Spdan, fr. Spd, n.; akin to D. Spoeden, G. Sich sputen. See Speed. 1. Prosperity in an undertaking; favorable issue; success. "For common speed." "O Lord God of my master Abraham, I pray thee, send me good speed this day." (Gen. Xxiv. 12) 2. The act or state of moving swiftly; swiftness; velocity; rapidly; rate of motion; dispatch; as, the speed a horse or a vessel. "Speed, to describe whose swiftness number fails." (Milton) In kinematics, speedis sometimes used to denote the amount of velocity without regard to direction of motion, while velocity is not regarded as known unless both the direction and the amount are known. 3. One who, or that which, causes or promotes speed or success. "Hercules be thy speed!" God speed, Good speed; prosperity. See Godspeed. Speed gauge, Speed indicator, and Speed recorder, a power lathe with a rapidly revolving spindle, for turning small objects, for polishing, etc.; a hand lathe. Speed pulley, a cone pulley with steps. Synonym: Haste, swiftness, celerity, quickness, dispatch, expedition, hurry, acceleration. See Haste. Origin: AS. Spd success, swiftness, from spwan to succeed; akin to D. Spoedd, OHG. Spuot success, spuot to succees, Skr. Spha to increase, grow fat. B. Source: Websters Dictionary (01 Mar 1998) |

| swimming speed | <marine biology> Swimming speeds of stream fish vary from essentially zero to over six metres per second, depending upon species, size, and activity. Three categories of performance are generally recognised: 1. Burst (darting) speed: The speed that a fish can maintain for a very short time, generally 5 to 10 seconds, without gross variation in performance. Burst speed is employed for feeding or escape, and represents maximum swimming speed. 2. Cruising speed: The speed that a fish can maintain for an extended period of time without fatigue. This implies a lack of stress, and is the maximum speed traveled by undisturbed individuals. 3. Sustained (prolonged) speed: The speed that a fish can maintain for a prolonged period, but which ultimately results in fatigue. at this speed the fish is under some degree of stress. (19 Jan 1998) |
| film speed | The relative sensitivity of film emulsion to light or radiation exposure; speed is inversely related to detail resolution. (05 Mar 2000) |
| atomic volume | The atomic weight of an element divided by its density in the solid state; the volume of the gram-atomic weight of a solid element. (05 Mar 2000) |
| blood volume | Volume of circulating blood. It is the sum of the plasma volume and erythrocyte volume. (12 Dec 1998) |
| blood volume determination | Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight. (12 Dec 1998) |
| blood volume nomogram | A nomogram used to predict blood volume on the basis of the individual's weight and height. (05 Mar 2000) |
| cardiac volume | The volume of the heart, usually relating to the volume of blood contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is stroke volume. (12 Dec 1998) |
| packed cell volume | <haematology> Measurement of the proportion of the blood occupied by the red blood cells. Normal values are 40-54% in males, 35-47% in females. (13 Nov 1997) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| partial volume | The actual volume occupied by one species of molecule or particle in a solution; the reciprocal of the density of the molecule. (05 Mar 2000) |
| mean corpuscular volume | The average volume of red cells, calculated from the haematocrit and the red cell count, in erythrocyte indices. (05 Mar 2000) |
| residual volume | The volume of air remaining in the lungs at the end of a maximal expiration. Common abbreviation is rv. (12 Dec 1998) |
| volume | 1. A roll; a scroll; a written document rolled up for keeping or for use, after the manner of the ancients. "The papyrus, and afterward the parchment, was joined together [by the ancients] to form one sheet, and then rolled upon a staff into a volume (volumen)." (Encyc. Brit) 2. Hence, a collection of printed sheets bound together, whether containing a single work, or a part of a work, or more than one work; a book; a tome; especially, that part of an extended work which is bound up together in one cover; as, a work in four volumes. "An odd volume of a set of books bears not the value of its proportion to the set." (Franklin) 4. Anything of a rounded or swelling form resembling a roll; a turn; a convolution; a coil. "So glides some trodden serpent on the grass, And long behind wounded volume trails." (Dryden) "Undulating billows rolling their silver volumes." (W. Irving) 4. Dimensions; compass; space occupied, as measured by cubic units, that is, cubic inches, feet, yards, etc.; mass; bulk; as, the volume of an elephant's body; a volume of gas. 5. Amount, fullness, quantity, or calibre of voice or tone. <chemistry> Atomic volume, Molecular volume, the ratio of the atomic and molecular weights divided respectively by the specific gravity of the substance in question. <physics> Specific volume, the quotient obtained by dividing unity by the specific gravity; the reciprocal of the specific gravity. It is equal (when the specific gravity is referred to water at 4 deg C. As a standard) to the number of cubic centimeters occupied by one gram of the substance. Origin: F, from L. Volumen a roll of writing, a book, volume, from volvere, volutum, to roll. See Voluble. Source: Websters Dictionary (01 Mar 1998) |
| volume averaging | In computed tomography or magnetic resonance imaging, the effect of expressing the average density of a voxel as a pixel in the image; the greater the slice thickness, the more averaging is necessary, with loss in density resolution. (05 Mar 2000) |
