Record 1 2025-05-09

English

Subject field(s)
  • Astrophysics and Cosmography
DEF

Moving in unison with the overall expansion of the universe.

CONT

What do we mean by comoving coordinates? Comoving coordinates are coordinates that move along with the overall expansion of the universe. Imagine a distant galaxy. It is located at the coordinate(r, theta, phi). As long as no force acts on it, it will always be at that coordinate.

French

Domaine(s)
  • Astrophysique et cosmographie
DEF

Se dit d'un objet dont le seul mouvement consiste à être entraîné par l'expansion de l'Univers.

OBS

L'objet comobile est entraîné, mais ne se déplace pas par rapport à l'espace, qui lui-même se dilate.

OBS

comobile : désignation et définition publiées au Journal officiel de la République française le 26 janvier 2025.

Record 2 - external organization data 2005-11-09

English

Subject field(s)
  • Steam Turbines
  • Nuclear Fission Reactors
  • Compartment - Canadian Nuclear Safety Commission
CONT

The double flow turbine design not only provides double the expansion volume within a common casing, it also balances the large pressure drop between the turbine steam inlet and exhaust which tends to force the blade wheels from the high-pressure side towards the low-pressure side.... Steam enters the turbine in the middle of the casing and expands outward in both directions before exhausting at the ends of the turbine. In each half of the turbine, a very large thrust is generated. These thrusts oppose each other; the resultant force is significantly reduced.

French

Domaine(s)
  • Turbines à vapeur
  • Réacteurs nucléaires de fission
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Premièrement, une turbine à double flux permet de doubler le volume d'expansion dans une seule turbine. Deuxièmement, elle absorbe la forte chute de pression de la vapeur, qui se traduit par une force exercée sur les roues à ailettes depuis le côté haute pression vers le côté basse pression. [...] La vapeur pénètre dans la turbine par le milieu du corps et se dilate vers l'extérieur dans les deux directions, avant d'être évacuée aux deux extrémités de la machine. Chaque moitié de la turbine produit une très forte poussée.

Record 3 1997-02-18

English

Subject field(s)
  • Chemistry
DEF

The coefficients in an expansion of the intramolecular potential function in terms of a definite set of coordinates, the values of which define the deformation of the molecule away from its equilibrium configuration. In order to define force constants, one has to indicate both the definition of each coordinate and the expansion of the potential.

French

Domaine(s)
  • Chimie
DEF

Les coefficients d'une expansion de la fonction de potentiel intramoléculaire pris dans un ensemble de coordonnées définissant la déformation d'une molécule en fonction de sa configuration d'équilibre. Afin de définir les constantes de force, on doit préciser la définition de chaque coordonnée ainsi que l'expansion du potentiel.

Record 4 1986-12-12

English

Subject field(s)
  • Respiratory System
  • Physiotherapy
CONT

During inspiration, the force developed by the contracting muscles of inspiration meets progressively increasing(inward) recoil forces from the combined expansion of the lung and chest wall. Furthermore, because shortening muscle fibers generate progressively less force, inspiration finally ceases at that volume(total lung capacity) at which the weakening inspiratory muscle forces can no longer overcome the increasing forces required to expand the lungs and chest wall.

French

Domaine(s)
  • Appareil respiratoire
  • Physiothérapie
OBS

Modes de ventilation : assisté-contrôlé (...) autres paramètres : plateau, force inspiratoire (...)

OBS

Sevrage du respirateur des insuffisants respiratoires chroniques (IRC) en poussée asphyxique (IRA) : comparaison de la force inspiratoire (FI) vs la capacité vitale forcée (CVF). (Rev. Mal. Respir.//Revue des maladies respiratoires; ISSN 0761-8425; FRA; DA. 1985; Vol. 2; no 2; pp. 112)
