CENTER POLE [9 records]

Record 1 2025-08-26

English

Subject field(s)
  • Visual Disorders
CONT

Central areolar choroidal dystrophy(CACD) is a hereditary retinal disorder that primarily affects the macula. In the early stages, there is subtle, mottled depigmentation in the posterior pole. Ultimately, the depigmentation enlarges into in a well-circumscribed round or oval area of atrophy of the retinal pigment epithelium(RPE) and choriocapillaris in the center of the macula. Patients usually become symptomatic in the [third] to [fourth] decade when a fine, hardly detectable, mottling of the RPE leads to the development of absolute central visual scotomas. Later, between the [fourth] and [seventh] decade of life, progressive macular atrophy leads to a dramatic decline in central visual acuity and severe visual disability. CACD may be autosomal dominant or recessive; however, autosomal-recessive cases are rare. Although CACD has a genetic basis, sporadic cases have been reported.

Record 3 2010-10-14

English

Subject field(s)
  • Sports Equipment and Accessories
  • Camping and Caravanning
  • Parks and Botanical Gardens
CONT

Pyramidal tents. These tents..., which are usually tall, were formerly erected with a center pole that was always in the way like a sore thumb; however, the now feature other means of support.... However, the bulk and weight of these tents usually make them impractical for light-trip camping.

French

Domaine(s)
  • Équipement et accessoires de sport
  • Camping et caravaning
  • Parcs et jardins botaniques
CONT

Tente pyramidale. Dite "monomât" (à un seul mât), cette tente dont la toile s'ancre directement au sol, est très légère et se monte rapidement. Certains modèles comportent une avance qui en augmente l'habitabilité. Le type Itisa et ses variantes est très apprécié des randonneurs.

Record 4 2009-01-23

English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Tectonics
  • Scientific Measurements and Analyses
  • Archaeology
CONT

To the extent that artifacts vary from a surface they will be pulled towards the isotropic pole. Thus, the last simulated data set was created by giving 200 artifacts random bearings(0-360°) and random plunges(0-90°). From the Schmidt diagram... it is clear that there is no patterning in these data. Points are as likely to plot near the edges as near the center of the diagram and the Rose diagram shows an approximately uniform distribution of bearings.

OBS

plunge: The angle a fold axis or linear feature makes with the horizontal, measured in a vertical plane.

OBS

random plunge: term used at Natural Resources Canada - Earth Sciences Sector.

Record 5 2008-12-05

English

Subject field(s)
  • Plate Tectonics
DEF

Pole passing through the center of the earth about which a plate can rotate as a rigid body from any initial to any final position on the earth's surface.

CONT

The rotation axis pierces the surface of the earth at two points called poles of rotation, or eulerian poles.

CONT

The first paleogeographic map of the Mediterranean was constructed by Dewey et al. (1973) using finite Eulerian poles of rotation for the lithospheric plates and paleomagnetic data from the Atlantic oceanic crust. This method, highly innovative at the time, was based on the following criteria: i) the determination of the Eulerian rotation poles with the oceanic magnetic anomalies or, where this is not possible, with the tectonic structures identified on the plate margins ...

Domaine(s)
  • Tectonique des plaques
DEF

Point d'intersection du globe terrestre et de l'axe (axe eulérien) passant par son centre, et autour duquel se font les mouvements relatifs de deux plaques lithosphériques en contact [...]

CONT

On appelle ces pôles de rotation relative les pôles eulériens pour les distinguer du pôle de rotation de la terre (pôle rotationnel ou géographique) et des pôles paléomagnétiques.

Record 7 2003-01-23

Subject field(s)
  • Physical Geography (General)
DEF

An azimuthal map projection having the pole of the projection at the center of the area mapped. The azimuths of great circles radiating from this center(pole) are truly represented on the map : equal distances on those great circles are represented by equal linear distances on the map, but the scale along those great circle lines so varies with distance from the pole of the projection, that an equal-area projection is produced.

French

Domaine(s)
  • Géographie physique (Généralités)
DEF

Projection azimutale dont le pôle se trouve au centre de la surface cartographiée. Les azimuts des grands cercles rayonnant à partir de ce centre sont véritablement représentés par des distances linéaires, équivalents sur la carte, mais la variation de l'échelle le long de ces grands cercles en fonction de la distance à partir du pôle de la projection est telle que l'on obtient une projection équivalente.
