Record 2 2024-10-31

English

Subject field(s)
  • Biological Sciences
  • Immunology
  • Lymphatic System
CONT

As blood flows through the central arteries [of the spleen], it reaches the marginal zone, a region between the white pulp and red pulp. The marginal zone contains macrophages and other immune cells that capture and process antigens, contributing to the spleen's immunologic function.

French

Domaine(s)
  • Sciences biologiques
  • Immunologie
  • Système lymphatique
CONT

La zone marginale est un compartiment anatomique distinct [...]

Spanish

Campo(s) temático(s)
  • Ciencias biológicas
  • Inmunología
  • Sistema linfático

Record 3 2021-07-14

English

Subject field(s)
  • Plate Tectonics
  • Vulcanology and Seismology
DEF

[The] place where an oceanic tectonic plate dives under either a continental plate or under another oceanic plate.

CONT

A subduction zone is typically marked by an oceanic trench, lines of volcanoes and crustal deformation associated with mountain building.

OBS

subduction zone: term used at Natural Resources Canada - Earth Sciences Sector.

PHR

Active, extinct subduction zone.

PHR

Subduction zone boundary.

French

Domaine(s)
  • Tectonique des plaques
  • Volcanologie et sismologie
DEF

Zone de convergence où une portion de la lithosphère océanique s'enfonce sous une plaque continentale ou une autre plaque océanique, avec formation d'une fosse océanique et accompagnée d'un volcanisme actif.

OBS

zone de subduction : terme en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.

PHR

Zone de subduction active. Ancienne zone de subduction.

PHR

Frontière formée de zones de subduction.

Spanish

Campo(s) temático(s)
  • Tectónica de placas
  • Vulcanología y sismología
DEF

Zona marginal en la que una placa cortical es absorbida, bajo otra placa, por el manto superior, a lo largo de una superficie sísmica de Benioff.

Record 4 2002-03-27

English

Subject field(s)
  • Cytology
  • Nervous System
  • Biotechnology
DEF

A sensory neuron that differentiates before the others and forges an axonal path from the periphery to the CNS [central nervous system] for the other (follower) cell axons to follow.

CONT

Follower neurons do not need special pathfinding abilities. If pioneer cells are killed, however, the next sensory neuron will differentiate into a pioneer cell and find its way to the CNS [central nervous system].

CONT

Axon growth along pathways formed by guideposts often results in the establishment of pioneer neurons. Their axons serve as a pathway for additional neurons that develop later in the embryo and project their axons to the appropriate target. In many systems pioneer neurons are eliminated by programmed cell-death and are not present in the adult.

French

Domaine(s)
  • Cytologie
  • Système nerveux
  • Biotechnologie
CONT

Les cellules pionnières sont des neurones envoyant des prolongements et qui serviront de guide pour d'autres cellules.

Spanish

Campo(s) temático(s)
  • Citología
  • Sistema nervioso
  • Biotecnología
CONT

Hemos encontrado dos grandes variedades de neuronas precoces durante los estadios iniciales de la corticogénesis en la rata. La primera variedad está constituida por las neuronas corticales pioneras, que nacen en el neuroepitelio ventricular del primordio cortical [...] Estas células, que muestran inmunorreactividad intensa para calbindina y calretinina, se caracterizan por su gran tamaño y su proyección axonal y permanecen en la zona marginal después de la formación de la placa cortical. Proyectan primero a la zona ventricular y después a la subplaca y cápsula interna. Son, consecuentemente, el origen de la proyección eferente más precoz de la corteza en desarrollo. Las neuronas pioneras solamente se observan en el cerebro prenatal.

Record 5 2001-05-09

English

Subject field(s)
  • Telecommunications Transmission
  • Radio Transmission and Reception
DEF

An area at such a distance from the transmitter that the signals received are weak.

French

Domaine(s)
  • Transmission (Télécommunications)
  • Émission et réception radio

Spanish

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

Zona situada a una distancia tal del transmisor que las señales que se reciben son débiles.
