In reversible inhibition of enzymes... the inhibitor participates in a rapidly established, easily reversible equilibrium with the enzyme or enzyme-substrate complex, which can be analyzed in terms of the Michaelis-Menten formalism.... The three major types of reversible enzyme inhibition, competitive, uncompetitive, and noncompetitive, can be experimentally distinguished by the effects of the inhibitor on the reaction kinetics of the enzyme, which may be analyzed in terms of the basic Michaelis-Menten rate equation. For valid kinetic analysis the inhibitor must combine rapidly and reversibly with the enzyme or enzyme-substrate complex. 2, record 2, English, - reversible%20inhibition

Inhibition non permanente où l'inhibiteur ne se combine pas de façon covalente sur l'enzyme. L'inhibition est dans ce cas un processus rapide. En général, une dialyse, éliminant l'inhibiteur, restaure l'activité de l'enzyme. Les inhibiteurs agissant de cette façon sont assez spécifiques.

In the homogeneous equilibrium model (HEM) one assumes that the velocity, temperature and pressure between the phases or components are equal. 1, record 3, English, - homogeneous%20equilibrium%20model
Record number: 3, Textual support number: 1 OBS
This assumption is based on the belief that differences in these three potential variables(and chemical potential if chemical reactions are considered) will promote momentum, energy, and mass transfer between the phases rapidly enough so that equilibrium is reached. For example, when one phase is finely dispersed in another phase generating large interfacial area, under certain circumstances this assumption can be made; e. g., bubbly flow of air in water or steam in water at high pressures. The resulting equations resemble those for a pseudo-fluid with mixture properties and an equation of state which links the phases to obtain these mixture thermodynamic properties. Whenever the HEM model is used it is advisable to check the validity of the equilibrium assumptions by using more accurate theoretical models for comparison. For example, rapid acceleration or pressure changes cannot be always accurately modelled with the HEM model; i. e., discharge of flashing vapor-liquid mixtures, or shock wave propagation through a multiphase medium. This is especially true when the pressure change is large when compared to the ambient pressure, or any of the driving potentials are large relative to their reference values. 1, record 3, English, - homogeneous%20equilibrium%20model

Les écoulements à direction privilégiée peuvent soit être considérés comme monodimensionnels, soit conduire à des équations simplifiées en ne considérant que les termes prédominants. Le modèle le plus simple revient à homogénéiser les deux phases en considérant un fluide dont les propriétés physiques sont déterminées par le taux de présence des deux phases. En écoulement à direction privilégiée (vertical ascendant), les deux phases étant en équilibre thermodynamique et mécanique, le modèle homogène à l'équilibre (HEM) se révèle satisfaisant et particulièrement utile. À partir de ce modèle, on peut introduire des effets de glissement ou de déséquilibre thermique (apparition de vapeur lorsque le fluide n'est pas encore à saturation). 1, record 3, French, - mod%C3%A8le%20homog%C3%A8ne%20%C3%A0%20l%27%C3%A9quilibre

The Boltzmann equation, also often known as the Boltzmann transport equation, devised by Ludwig Boltzmann, describes the statistical distribution of one particle in a fluid. It is one of the most important equations of non-equilibrium statistical mechanics, the area of statistical mechanics that deals with systems far from thermodynamic equilibrium; for instance, when there is an applied temperature gradient or electric field. The Boltzmann equation is used to study how a fluid transports physical quantities such as heat and charge, and thus to derive transport properties such as electrical conductivity, Hall conductivity, viscosity, and thermal conductivity. 1, record 4, English, - Boltzmann%20equation

La population des neutrons dans un réacteur nucléaire peut être, à la fois, qualifiée de nombreuse et de diluée. Par exemple, dans un réacteur à eau sous pression fonctionnant dans les conditions nominales, il y a, en permanence, de l'ordre de cent millions de neutrons par centimètre cube : cela est largement suffisant pour qu'une description statistique et non individuelle des particules soit faite; cependant, ces neutrons sont approximativement 1014 fois moins nombreux que les noyaux (on en compte de l'ordre de 1022 par cm³ dans la matière usuelle), ce qui fait que les interactions neutrons sont totalement négligeables devant les interactions neutrons- matière; en conséquence, l'équation décrivant la densité de la population des neutrons sera linéaire. Cette équation est l'équation écrite par Boltzmann en 1879 dans le cadre de la théorie statistique des gaz et qui a pu être reprise pratiquement dans les mêmes termes pour décrire le «gaz» neutronique. 1, record 4, French, - %C3%A9quation%20de%20Boltzmann
