Record 1 2024-05-23

English

Subject field(s)
  • Astrophysics and Cosmography
  • Launching and Space Maneuvering
CONT

The eccentricity(e) of an orbit indicates the deviation of the orbit from a perfect circle. A circular orbit has an eccentricity of 0, while a highly eccentric orbit is closer to(but always less than) 1.

OBS

circular orbit: term officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Astrophysique et cosmographie
  • Lancement et manœuvres dans l'espace
CONT

Une orbite circulaire est [...] une orbite dont l'excentricité est nulle.

OBS

orbite circulaire : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Record 2 2013-02-20

English

Subject field(s)
  • Modelling (Mathematics)
  • Climatology
OBS

VICBAR stands for Vic Ooyama's barotropic model. The model is initialized with deep layer mean winds and geopotential heights from a mass-weighted average of the 850, 700, 500, 400, 300 and 200 mb levels. Analyses are produced on three nested grids :(1) a fixed synoptic domain 27. 5 S to 67. 5 N, 10 E to 140 W;(2) a storm environment 50 degree latitude-longitude box centered on the current storm location; and(3) a vortex domain circle of 7. 4 degree(about 800 km) radius centered on the current storm location.

Record 3 2002-12-19

English

Subject field(s)
  • Radio Transmission and Reception
DEF

In ionospheric propagation between points on the earth's surface, the points in the ionosphere distant 2000 km and 1000 km along the great circle form each terminal which are assumed to control transmission by way of the F2 and E layers respectively.

OBS

When the distance between the terminals is less than 4000 km, or 2000 km, the control points for F2 layer and E layer transmission respectively are at the mid-point off the path.

French

Domaine(s)
  • Émission et réception radio
DEF

Point de la couche E (F2) dont la projection sur la surface de la Terre est située à 1000 km et 2000 km de l'émetteur ou du récepteur sur l'arc de grand cercle qui les joint. b) Point milieu de l'arc de grand cercle quand la distance est inférieure à 2000 km ou 4000 km pour la transmission par la couche E (F2).

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
DEF

Punto de la capa E y de la capa F2 respectivamente, que controlan la transmisión y cuya proyección sobre la superficie de la tierra está situada a 1000 y a 2000 km del transmisor o del receptor sobre el gran círculo que les une.

OBS

En propagación ionosférica. Cuando la distancia entre los terminales es menor de 4000 km o 2000 km, los puntos de control para la capa F2 y la capa E de transmisión respectivamente, están en el punto medio del trayecto.

Subject field(s)
  • Paleontology
  • Algebra
CONT

The geometrical constructions explaining shell coiling in general have been based since the first part of the nineteenth century on the logarithmic ... spiral ...

CONT

As pi is to the circle, e is to the logarithmic spiral. This curious number plays a central role in nature and in mathematics.

French

Domaine(s)
  • Paléontologie
  • Algèbre
CONT

[Dans une] "spirale logarithmique", [...] la largeur du tour va en croissant, donc [...] le rayon vecteur suit une progression géométrique.

Subject field(s)
  • Economic Conditions and Forecasting
CONT

We are entering a world that will be dominated by engineering, ... when the driving force of the global economy will no longer be inexpensive microchips in plentiful supply but cheap genes by the bushelful. ... Among the potential big engines of growth in the fourth circle: genetic engineering and biotechnology, artificial intelligence, the business of space, [and] new materials, including ceramic composites and combinations of metals or plastics with fibers.

CONT

In the next great circle of growth, the Fourth Circle, the economy will be driven by a whole new set of engines....

Record 6 1985-08-15

English

Subject field(s)
  • Air Pollution
CONT

[In the equation] Q1 is the effective sulphur dioxide emission for long-range transport. A certain smaller part of the emissions is deposited locally and never mixes throughout the mixing layer.

CONT

Defining the area affected by the initial phase as a circle with 70 km radius surrounding the source gives E/Q-values that vary with city size... Thus the analysis does not support the idea that a major portion of the sulfur emitted in a city like Paris is deposited locally. This is an important conclusion, as it lends support to the fundamental idea that most of the sulfur dioxide emitted from a heavy source area survives the initial phase when the pollutants are confined to the air layers relatively close to the ground.

French

Domaine(s)
  • Pollution de l'air
DEF

Relativement à une distance inférieure à 100 kilomètres ou inférieure à 48 heures de transport atmosphérique.

CONT

L'augmentation de l'acidité des précipitations sur la plus grande partie de l'Europe et sur une partie des Etats-Unis est en fait reliée à un problème beaucoup plus grave de changement du climat chimique causé par une variété d'émissions dans l'atmosphère. Ces émissions peuvent créer une situation critique localement, régionalement ou globalement en fonction de la durée de vie des polluants rejetés dans l'atmosphère, de l'intensité des émissions et des conditions météorologiques.
