FATIGUE LIFE, in a strength of materials - ability of materials and designs to oppose to action of repeated (cyclical) loads.

STIMULATED RADIATION (induced radiance), process of emitting of electromagnetic waves by excited atoms and other quantum systems under action of external (forcing) radiance. Frequency, a phase, polarization and a direction of released and forcing radiance coincide.

FORCED VIBRATIONS, arise in system under action of periodic{batch} external action (napr., forced vibrations of a floating lever under action of periodic{batch} force, forced vibrations in an oscillating circuit under action of periodic{batch} electromotive force). If frequency of influence comes nearer to a free-running frequency of system, there occurs a resonance.

The FRANK PROLAPSE, vyhozhdenie a uterus and walls of a sheath for limits a genital hiatus, is routine for elderly, it is a lot of rozhavshih women having lacerations of the perineum, started soon after stems to heavy physical work. It is quite often accompanied by an incontience wet. It is marked and for animal.

PROLAPSE OF THE RECTUM, the partial or full ectropion of a rectum through an anal orifice at slackening tissues of a perineum and a bottom of a pelvic cavity. Immediate causes: major exercise stresses, traumas, etc. It is marked and for animal.

VAPORIZATION, secretions of dissolved solids or obtaining of the clear solvent execute for concentrating solutions. To vaporization expos predominary water solutions nonvolatile or maloletuchih substances. In an industry vaporization effect in evaporators.

The BITTERN, two stems of birds of a set of herons: major a bittern (4 kinds, length up to 80 sm) and small a bittern, or water shoots (7 kinds{views}, length ok. 35 sm). Legs and a neck are shorter, than for the majority of herons. Are distributed widely.

VYPOLZOK, the national title of an outside keratosic layer of a leather the snakes, dropped by her{it} during a molting.

EXUDATE, the liquid soaking from small-sized blood vessels in a tissue or a perigastrium at an inflammation (see. An exudate), dropsies (see. A transudate).

VYPRAVITELNYE STRUCTURES, the same, that reguljatsionnye structures.

The RECTIFIER ELECTRICAL, the transducer of a variable current flow in permanent. The rectification of a current is routine implements an electrical valve for which phylum distinguish rectifiers electrical: vacuum, discharge, semiconductor, electrocontact. Apply in devices of automatics and a telemechanics, radio engineering (single-phase rectifiers electrical) and to a feed of potent plants (zigzag rectifiers electrical).

RECTIFYING PILE, the rectifier electrical by the way tandem semiconductor elements. Has a high allowable reverse voltage (up to tens kV). Some rectifying piles in a unified body will derivate the rectifier stack assembly.

RECTIFICATION, in the electrical engineer - transformation{conversion} of a current flow of a variable direction to a unidirectional current.

CONVEX CURVE, see in an item. Convex range.

The CONVEX RANGE, the part of a plane having that property, that a cutting bridging its{her} two any point is contained in her bodily. Any cohesive part of border{limit} of convex range calls as a convex curve (are those, napr., a circle and its{her} any arch, a triangle).

CONVEX SURFACE, see in an item. A convex body.

*ÂÛÏÓÊËÎÅ the BODY, a geometric object having that property, that the cutting bridging his{its} two any point is contained in a nem bodily (napr., the body a is convex, the body is not convex). A sphere, a cube - examples of a convex body. Any cohesive part of border{limit} of a convex body calls as a convex surface.

*ÂÛÏÓÊËÎÑÒÜ And the CONCAVE CAMBER, properties of the plot of the function y = f (x) (curve), consisting in a volume, that each arch of a curve is not higher (buldge from top to bottom, or a concave camber up) or is not lower (a concave camber from top to bottom, or buldge up) than its{her} subtending chord.

LEVELLING, in statistics - a method through which receive analytical and actuarial expression of the regularity basing the given empirical lines of statistical data.

INDICATIVE MOTIONS, express mental (especially emotional) conditions animal and the person, intonations of a voice, gestures, etc. show in a facial expression, pantomimike.
