CRITICAL FALL [9 records]

Record 1 2022-02-01

English

Subject field(s)
  • Search and Rescue (Paramilitary)
CONT

Crevasse rescue is complicated and challenging to execute in emergency situations; it's much better to make decisions that prevent a fall from happening in the first place. Most mountaineers will probably never have to use rescue skills, but the one time [they] might need those skills, it's absolutely critical that [they’re] competent in them.

Record 2 2020-08-07

English

Subject field(s)
  • PAJLO
  • Family Law (common law)
CONT

Family law is critical to most Canadians as it governs relationships between spouses, and between parents and their children. In family law, marriage and divorce fall under federal jurisdiction but most other issues, including adoption and matrimonial property disputes, fall under provincial laws that vary widely.

Subject field(s)
  • Soil Improvement and Fertilizer Management
  • Cultural Practices (Agriculture)
CONT

While having good fertility levels for a forage crop in the fall is critical for optimum production, fall fertilization is only one part of the management system to achieve this. Optimum soil test levels should be established prior to seeding and a maintenance fertilization program based on regular soil testing are the foundation of good nutrient management of forages.

CONT

A single application of fertilizer should not provide more than 1 pound of soluble nitrogen per 1,000 square feet. ... For maintenance fertilization, 4- to 6-week intervals are satisfactory.

French

Domaine(s)
  • Fumure et amélioration du sol
  • Soin des cultures (Agriculture)
DEF

Quantité d'engrais appliquée en vue de maintenir le niveau de fertilité chimique du sol.

CONT

À la différence des analyses foliaires ou pétiolaires qui permettent d'ajuster la fertilisation d'entretien, les analyses de bois sont en quelque sorte une «empreinte de la fin du millésime», avec prise en compte de la mise en réserve des souches.

Record 4 2002-11-22

English

Subject field(s)
  • Meteorology
CONT

Precipitation processes are complex.... Snow crystals begin as minute ice particles which have formed around condensation nuclei in the atmosphere. These nuclei may be dust particles with favorable molecular structure or even minute crystals of sea salt. If these ice particles exist in an atmosphere with an excess supply of water vapor(supersaturated air) they will continue to grow. Upon reaching a critical size, they begin to fall. Depending on the conditions they encounter in different layers of air during their descent, they may continue to grow, may stop growing, or may experience a succession of growth patterns. What arrives at the ground can be a simple product of the initial ice crystal formation, or it may be the result of a complex life history.

Key term(s)
  • ice germ
  • particle of ice
  • germ of ice

French

Domaine(s)
  • Météorologie
CONT

La naissance de «germes de glace» à partir de microgouttelettes d'eau surfondue cristallisant autour d'un noyau de congélation, et la croissance de ces germes en un cristal du système hexagonal (symétrie d'ordre six) conduisent à la formation de la neige au sein des nuages.

CONT

Les cristaux de neige prennent naissance dans les nuages. Les gouttes d'eau en surfusion rencontrent des germes de glace (particules de poussières ou gouttes gelées) pour ainsi donner les cristaux de glace.

CONT

nuage : ensemble visible de minuscules particules d'eau liquide ou de glace, ou des deux à la fois, en suspension dans l'atmosphère.

Record 7 1993-03-25

English

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

During delignification, there is also a corresponding reduction in pulp viscosity.... If pulp viscosity is allowed to fall below a critical level, the pulp strength drops dramatically. Maintenance of pulp viscosity is the principal reason that the kraft cook must be terminated at a point where a substantial level of residual lignin remains with the fibers. A derivation termed the G-factor(exactly analogous to the H-factor) can be applied for viscosity reduction, i. e., combinations of time and temperature that give the same G-factor can be expected to produce pulp with the same viscosity. Since the G-factor increases more rapidly with temperature than the H-factor, it follows that higher cooking temperatures have a proportionally greater effect on viscosity reduction.

English

Subject field(s)
  • Fluid Mechanics and Hydraulics (Physics)
CONT

As a black region forms, sometimes thin rivers of black will flow into the coloured area of the film. Critical fall, as this is known, usually happens with soap solution having more than 4% of surfactants. What causes critical fall? First, an island of thicker silver-white film is caught in the thinner black film....

OBS

"critical": relating to, indicating, or being a state in which or a measurement or point at which some quality, property, or phenomenon suffers a finite change or undergoes drastic alteration.

  • Mécanique des fluides et hydraulique (Physique)

English

Subject field(s)
  • Statistical Graphs and Diagrams
  • Hydrology and Hydrography
DEF

The longitudinal shape of the water surface in a stream or open conduit upstream from a point where a sudden fall occurs, as when flowing water passes over a dam, weir, or other obstruction. In uniform channels the curve is convex upward. The depth at all points is greater than Belanger's critical depth and less than normal depth, and velocities increase downstream, the flow being nonuniform.

French

DEF

Dans un écoulement à surface libre, forme particulière de la ligne d'eau qui suit une courbe convexe, par exemple, dans une nappe de déversement libre par-dessus un déversoir.
