Carmichael (1978) introduced the concept of metamorphic bathozones and bathograds as a measure of the depth of regional post-metamorphic uplift and erosion. This concept is used ... to complement the limited quantitative barometry currently existent ... Where quantitative information about P-T [pressure-temperature] is presented herein, the equivalent bathozone is given in brackets for convenience; it should be recognized, however, that pressures derived from quantitative barometry and mineral assemblages are not directly equivalent. ... Using five bathograds Carmichael (1978) defined six bathozones, numbered from 1 to 6 in order of increasing pressure ... 2, record 1, English, - bathozone

Reactions that release a large quantity of free energy are those that have a very large negative [delta]G and create much disorder. Such reactions will have a strong tendency to occur, although the rate at which they do so will depend on other factors, such as the availability of specific enzymes. Conversely, reactions with a positive value of [delta]G create net order in the universe and cannot occur spontaneously. Such energetically unfavorable reactions will happen only if they are coupled to a second reaction with a negative [delta]G so large that the [delta]G of the entire process is negative. 3, record 2, English, - free%20energy

Notons que l’enzyme ne détermine pas le sens de la réaction; la proportion de molécules X et Y, à l’équilibre, dépend de facteurs thermodynamiques : la réaction favorisée est celle qui minimise ce que l’on appelle l’énergie libre. (L’énergie libre d’un système est égale à son énergie totale diminuée de son entropie, c’est-à-dire d’une quantité qui caractérise le désordre du système.) 3, record 2, French, - %C3%A9nergie%20libre

Pour caractériser une réaction, on parle aussi de variation d’enthalphie libre [delta] G=[delta] U + P[ delta] V-T[ delta] S où P est la pression et [delta] V, la variation de volume. En biochimie, on peut admettre que [delta] V=0, car les variations de volume pour les réactions ayant lieu en solution sont négligeables. Ainsi, [delta] G=[delta] U-T[ delta] S=[delta] F. Par conséquent [delta] F se confond avec [delta] G. Ceci est vrai surtout si les réactions font intervenir des liquides et des solides en solution(et aucun gaz) aux températures physiologiques qui sont basses. 4, record 2, French, - %C3%A9nergie%20libre

The commercially-available sling pump consists of a helically-wound hose within a drum-shapedbody that has a propeller at the front. A swivel coupling at the front end of the pump allows the body of the pump to rotate freely without affecting the discharge pipe. Water flowing past the propeller at the front of the unit sets the entire body of the pump in a slow rotational motion. Alternating slugs of air and water enter the intake of the spiral hose and are forced along the pipe by the rotational motion of the pump. The sling pump can also be powered by the wind, instead of flowing water. Because the swivel coupling is the only mechanical component comprising the pump, it is virtually maintenance-free. 2, record 4, English, - sling%20pump

La pompe à hélice, ou pompe P, est souvent considérée comme parfaitement adaptée à un grand nombre d’applications nouvelles. Un nombre croissant d’entre elles servent à l'irrigation et au drainage. Elles permettent aussi de réguler le niveau de l'eau des canaux. Beaucoup d’installations en sont équipées et on leur assigne des tâches de tout ordre-de l'irrigation des champs au pompage des eaux en cas de pluie torrentielle ou d’inondation. Dans le nord de la France et dans le delta du Pô en Italie, nos pompes P servent à irriguer pendant l'été des terres agricoles [...] 2, record 4, French, - pompe%20%C3%A0%20h%C3%A9lice

In gyroscopes, degrees of freedom refer to the restraints imposed upon the gyroscope wheel spin axis. Any rotation about the input axis will result in a precession of the gyroscope wheel. Thus, a voltage from the gyroscope pickoff will cause the wheel-gimbal stabilizing motor to drive and return the gyroscope wheel to its zero precession angle. 1, record 5, English, - zero%20precession%20angle
