The ability of a vessel to return to its upright position after being heeled by an external force, such as the wind, a wave or the strain from its fishing gear.

CONT

[The] stability ... is determined by the characteristics of the vessel, such as hull form and weight distribution and how the vessel is operated. The stability ... is not a constant condition; it undergoes continuous changes during each voyage and through the vessel’s life.

DEF

Capacité d'un navire à revenir à sa position verticale après avoir été incliné par une force extérieure, comme le vent, une vague ou la tension exercée par ses engins de pêche.

CONT

La stabilité [...] est déterminée par les caractéristiques du navire telles que la forme de la coque et la répartition du poids ainsi que la façon dont le navire est exploité. La stabilité [...] n'est pas un état constant; elle subit des changements continus au cours de chaque navigation ainsi que tout au long du cycle de vie du navire.

Subject field(s)
  • Petrography
CONT

OPG [Ontario Power Generation] indicated that changes in ground stress, induced by surface glacial loads through the earliest two glacial ice ages during the initial 150, 000 year period following decommissioning, would not affect pillar stability. Beyond 300, 000 years after decommissioning, OPG expected that the effects of several ice ages would cause significant rock failure and roof collapse within repository rooms.

Record 5 2012-08-13

English

Subject field(s)
  • Curling
  • Footwear (Clothing)
CONT

To play curling, curlers wear shoes with two different types of sole. To one foot(the grip foot), a grip sole allows the initial push in the hack and gives stability while sweeping. To the other foot(the sliding foot), a sliding sole eases the slide on the ice while delivering the rock and sweeping or brushing the ice in front of a moving rock.

OBS

The expression "curling boots" is improper, since curlers are using low-cut shoes to play.

French

Domaine(s)
  • Curling
  • Chaussures (Vêtements)
CONT

Au curling, les joueurs portent des chaussures avec deux types de semelle. À un pied (le pied antidérapant), une semelle antidérapante permet la poussée au départ et la stabilité au moment d'effectuer le balayage. À l'autre pied (le pied de glissade), une semelle de glisse permet la glissade sur la glace au moment de placer sa pierre ou de balayer ou de brosser devant une pierre en mouvement.

OBS

L'expression «bottes de curling» est inappropriée puisque les curleurs utilisent des chaussures à coupe basse pour donner plus d'aise au pied en jouant.

  • bottes de curling

Record 6 2011-10-21

English

Subject field(s)
  • Biological Sciences
CONT

Enzymes which show excellent thermal stability and even more favorable kinetics do not necessarily show excellent operational stability. Operational stability is not only a function of thermal stability but includes such factors as carrier and feed composition, dimensional and chemical stability.... The thermal and chemical stability of enzymes is usually analyzed by measuring variations in initial rates of the enzymatic reaction, or in some protein structure-related physicochemical property, as a function of operating conditions(temperature, pH, denaturant, concentration, etc.)

French

Domaine(s)
  • Sciences biologiques
CONT

La stabilité chimique et physique du support autorise des nettoyages systématiques pouvant inclure l'emploi de solvants, de solutions acides, basiques ou enzymatiques. Ces lavages peuvent être fréquents et ne perturbent pas le bon fonctionnement ultérieur de la colonne.

English

Subject field(s)
  • Biological Sciences
  • Biotechnology
CONT

The stability of an enzyme... usually refers to the conformational stability of the protein. The thermal, organic solvent, urea, pH, and storage stability of an enzyme are largely determined by its conformational stability, and inactivation is caused primarily denaturation... The stability of a biocatalyst is usually expressed by means of a half-life value, i. e. the time required for the activity of the reactor to fall to half of its initial activity. It is obviously desirable for the activity to be as stable as possible so that enzyme production and immobilization need only be carried out at infrequent intervals.

French

Domaine(s)
  • Sciences biologiques
  • Biotechnologie
DEF

Le fait de se trouver dans son domaine d'équilibre, de ne donner lieu à aucune réaction ou transformation spontanée.

CONT

La stabilité de l'édifice macromoléculaire est assurée par un grand nombre de forces d'interactions non covalentes de faible énergie : les liaisons hydrogène interamides, les liaisons hydrogène entre résidus des chaînes latérales et les interactions hydrophobes, c'est-à-dire, les interactions entre groupes non polaires. Pour certaines protéines, l'existence de ponts disulfures, liaisons covalentes, confère une stabilité supplémentaire en même temps qu'elle impose certaines restrictions à la conformation de la protéine.

OBS

La stabilité des enzymes est accrue lorsqu'elles sont immobilisées.

Ces compartiments sont généralement disposés dans les fonds [...]. Cependant, cette position au point le plus bas du navire peut conduire à une stabilité initiale trop importante; aussi quelques navires sont-ils munis de compartiments disposés en abord, dans les cales et quelquefois même dans les faux-ponts, permettant de faire remonter la position du centre de gravité de l'ensemble des poids du navire.

Subject field(s)
  • Pulp Preparation (papermaking)
DEF

Bleaching with a chlorine dioxide solution.

OBS

chlorine dioxide solution: A very unstable water solution of chlorine dioxide gas (ClO((subscript))2) produced in the chemical preparation area of a pulp mill. It is used in the pulp bleaching process.

OBS

The initial utilization of chlorine bleaching was in the later stages of a multi-stage bleaching sequence. The CEHDED sequence became dominant in the early 1960's for the production of full-bleach kraft pulp. As the cost of Cl02 became more competitive with sodium hypochlorite in the late 1960's, the CEDED sequence became the industry standard. In the 1970's, attention was given to replacing part of the chlorine in the chlorination stage with chemically equivalent chlorine dioxide to improve pulp strength and color stability and reduce effluent color....

Since the instability discussed up to now is the first to develop, it is called the primary instability. However, the convection cells that emerge can themselves be considered as a new basic state, the stability of which has to be studied. The characteristics of secondary instability modes that can appear are usually more difficult to understand since the new starting point is much more complicated than the initial basic state.

Subject field(s)
  • Radiography (Medicine)
  • Musculoskeletal System
DEF

A thin, horizontally oriented excrescence arising from the anterior surface of a vertebral body.

OBS

It is believed that traction and claw osteophytes represent different stages of a single disease process. Horizontally oriented excrescences, or traction osteophytes, initially form at the osseous site of attachment of the outer annular fibers(Sharpey fibers) to the anterior vertebral surface. Subsequently, periosteal deposition of bone and progressive disk ossification convert the traction osteophyte to a clawlike excrescence. It is possible that traction osteophytes, representing an initial stage of the ossification process, indicate an unstable discovertebral level, and that their conversion to claw osteophytes indicates increasing spinal stability that allows progressive ossification of annular fibers.

CONT

Static stability... refers to what happens to a parcel of air after it has been given an initial vertical displacement, either upwards or downwards. If, after an upward displacement, the parcel is found to be warmer(less dense) than its surroundings, its buoyancy will make it move farther from its original position; it will continue to move until its temperature(and density) become equal to that of its surroundings.
