The amount of work that must be done per unit quantity of pure water in order to transport reversibly and isothermally an infinitesimal quantity of water from a pool of pure water, at a specified elevation and at atmospheric pressure, to a pool of water identical in composition with the soil water at the point under consideration, but in all other respects being identical with the reference pool.  5, record 1, English, - osmotic%20potential

... solute potential. The tendency for water to undergo phase changes or to pass through membranes is controlled by the presence of solutes in the water. This is important in soil for two reasons :(1) evaporation of soil water is an important phase change,(2) water flow from soil into cells of organisms, including plant roots, requires transport through membranes.... As with matric potential, solute potential is never positive; it can be negative for impure water, or approximately zero for very pure water. Solute potential is also called osmotic potential, because the process of passing selectively through a semi-permeable membrane is called osmosis.  4, record 1, English, - osmotic%20potential

The separated flow model considers the phase to be artificially separated into two streams, one of liquid and one of vapour. In the model' s simplest form, each stream is assumed to travel at a mean velocity. For the case where the mean velocities of the two phases are equal the equations reduce to those of the homogeneous model.  1, record 3, English, - separated%20flow%20model

Two-Fluid Model. The final type of multiphase model is the multiple fluid model(better known as the two fluid model designating two phases or components). This model treats the general case of modelling each phase or component as a separate fluid with its own set of governing balance equations. In general each phase has its own velocity, temperature and pressure. The velocity difference as in the separated flow is induced by density differences. The temperature differences between the phases is fundamentally induced by the time lag of energy transfer between the phases at the interface as thermal equilibrium is reached.  1, record 4, English, - two%2Dfluid%20model

Avec l'augmentation de la puissance de calcul, l'application du modèle à deux fluides est devenue possible pour un temps de calcul raisonnable. Ce modèle a été développé dans les années 1970-1980 et intégré dans les codes de simulation au milieu des années 1980. Le modèle considère deux fluides qui s'écoulent ensemble dans un même espace et échangent masse, quantité de mouvement et énergie à leur interface. Il est nécessaire de définir des lois constitutives d'échange à utiliser avec les six équations disponibles, trois pour chaque phase (conservation de la masse, de la quantité de mouvement et de l'énergie).  1, record 4, French, - mod%C3%A8le%20%C3%A0%20deux%20fluides

Glueless wood welding... is very quick. The process consists in applying rapid, alternating mechanical friction to the two wood surfaces to be welded, under some pressure. The equipment for this type of work already exists as it is used to weld thermoplastics joints as used in the car industry. At the very high temperatures attained by mechanical friction(higher than 180°C) the characteristics of the wood lignin and hemicellulose between the wood cell walls change, and start to flow, hence the initial phase of "melting".  3, record 5, English, - rotation%20welding
