Squat refers to the increase of a ship's draught as a result of its motion through water. It is a hydraulic phenomenon whereby the water displaced creates an increase in current velocity past the moving hull causing a reduction in pressure resulting in a localised reduction of the water level and, consequently, in a settling of the vessel deeper in the water. For various reasons-having to do with hull design, trim and other physical and operational factors-squat may be different at the fore and aft.  2, fiche 1, Anglais, - squat

Le squat est l'augmentation du tirant d'eau d'un navire résultant du déplacement de celui-ci dans l'eau. Il s'agit d'un phénomène hydraulique par lequel l'eau déplacée crée une augmentation de la vitesse du courant le long de la coque en mouvement, causant ainsi une réduction de pression qui, à son tour, a pour effet de produire une baisse locale du niveau d'eau, permettant au navire de s'enfoncer plus profondément dans l'eau.  5, fiche 1, Français, - accroupissement

The two test firings of the engines took place 47 minutes apart. The first was at 05 : 27 h Central European Time. While it was a test burn only, it did serve as a small rendezvous manoeuvre for the module on its way to a linkup with the ISS [International Space Station]. The result of the burn was a 1 m/s increase in speed, placing Zvezda in an orbit with a perigee of 172 km and an apogee of 339 km. The second burn occurred 47 minutes later, at 06 : 14 h CET.

The jigging cycle for coal may be represented as a sine wave... in which water velocity is plotted against time. Starting from rest, the water commences to rise through the closely packed bed of coal with increasing velocity. Dilation of this bed begins with the loosening of the uppermost stratum.(In jigging coal it is possible to apply water so as to toss the whole bed solidly upward and then to allow it to open out upward and downward, but this is not feasible with heavy minerals.) As the water column attains a rising velocity of 100 mm./sec., the upper part of the coal bed opens and begins to teeter. Velocity continues to increase, and layer after layer opens until the whole bed is dilated and teetering. Then, as the pulsion stroke passes its peak, the velocity of the water lessens and the suction stroke begins.  5, fiche 4, Anglais, - dilation

Record number: 7, Textual support number: 1 CONT

The general principles of chemical-reaction kinetics apply to enzyme-catalyzed reactions, but they also show a distinctive feature not usually observed in nonenzymatic reactions, saturation with substrate.... At a low substrate concentration, the initial reaction velocity v_o is nearly proportional to the substrate concentration, and the reaction is thus approximately first order with respect to the substrate. However, as the substrate concentration is increased, the initial rate increases less, so that is is no longer nearly proportional to the substrate concentration; in this zone, the reaction is mixed order. With a further increase in the substrate concentration, the reaction rate becomes essentially independent of substrate concentration and asymptotically approaches a constant rate.  3, fiche 7, Anglais, - saturation

La théorie de la distorsion rapide […] est un vieux concept souvent considéré comme complémentaire des approches par viscosité turbulente. L'idée de base de la distorsion rapide est de dire que dans un cisaillement les structures turbulentes interagissent moins entre elles qu'avec le cisaillement lui même. Le nom de la méthode en découle : les structures turbulentes sont déformées et dissipées (ou incorporées au cisaillement moyen) rapidement, avant de pouvoir interagir entre elles. À l'origine [cette théorie] a été introduite pour calculer l'évolution de structures turbulentes tourbillonaires dans un milieu homogène présentant en particulier un cisaillement constant. Hunt (1973) la généralisa au cas des cisaillements inhomogènes. La [théorie de la distorsion rapide] s'apparentait alors à l'équation linéarisée d'évolution d'une turbulence fluctuante (traitée comme une perturbation d'un écoulement moyen) créant par rétroaction des tensions de Reynolds modifiant l'écoulement moyen.  1, fiche 8, Français, - %20th%C3%A9orie%20de%20la%20distorsion%20rapide

The substrate concentration yielding half-maximal velocity provides a useful index for the analysis of some enzyme regulatory mechanisms... Some allosteric enzymes respond to the binding of a modulator with a change in the apparent Km for the substrate, without change in Vmax. A negative modulator will then produce an increase in the apparent Km and a positive modulator a decrease in the apparent Km. Here the term "apparent Km" refers to the substrate concentration giving half-maximal velocity; it cannot be used to calculate enzyme since the vo-vs.-(s) relationship is not a rectangular hyperbola, as required by the Michaelis-Menten assumptions and equations.  4, fiche 10, Anglais, - half%20the%20maximal%20velocity

The speed of light in a vacuum is an important physical constant denoted by the letter c for "constant" or the Latin word "celeritas" meaning "swiftness". It is the speed of all electromagnetic radiations, including visible light, in a vacuum. More generally, it is the speed of anything having zero rest mass.... In metric units, the speed of light is exactly 299, 792, 458 metres per second(1, 079, 252, 848. 8 km/h). The fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299, 792, 458 of a second; any increase in the precision of the measurement of the speed of light would refine the definition of the metre, but not alter the numerical value of c. The approximate value of 3x10⁸ m/s is commonly used in rough estimates. In imperial units, the speed of light is about 670, 616, 629. 2 miles per hour or 983, 571, 056 feet per second, which is about 186, 282, 397 miles per second, or roughly one foot per nanosecond. The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity is called the refractive index of the medium.  5, fiche 13, Anglais, - speed%20of%20light

Vaned diffusers are used where importance is attached to the highest possible efficiency. By means of deflecting vanes in the diffuser guiding the flow in the radial direction, the velocity of the fluid can be reduced more than with a vaneless diffuser. In addition, the flow path through the forced deflection is shortened. Higher efficiencies and more compact geometries are obtained. Nevertheless, vaned diffusers also have disadvantages compared with vaneless ones : if the flow rate for a given vaned diffuser is much above the design flow rate, the profile losses increase considerably due to the high incidence angle.

The migration velocity is adjusted by the Cunningham correction factor for particle sizes below 1 [micron]. This correction largely accounts for the increase in migration velocity in the very small particle-size range. One consequence of the variation in migration velocity with particle size is that there will be a corresponding change in collection efficiency.  1, fiche 23, Anglais, - Cunningham%20correction%20factor

Fluidized-bed technique. The fluidized-bed technique [for mineral concentration] has been adopted in a number of processes to increase the economic recovery of metals from ores and concentrates. In this process, the material to be treated is kept in motion in a chamber by an upward current of gas that maintains the individual particles in suspension. Through precise adjustment of the velocity of the gas to conform with the grain size and specific gravity of the materials to be treated, a floating mixture of gas and solids is generated that behaves almost like a liquid. Increasing attention has been given to studies of high-temperature reactions in fluidized-bed systems, "high-temperature" implying(...) the practical limit of fuel-combustion heating.  1, fiche 31, Anglais, - fluidized%2Dbed%20technique

The fluid in contact with the surface of the cylinder rotates with the cylinder. Fluid at greater radius is also set in motion in concentric circles with velocity diminishing as the radius increase. This type of fluid motion, in which the velocity varies inversely as the radius, is referred to as a free vortex.  1, fiche 32, Anglais, - free%20vortex
