MATRIX MODE [6 records]

Record 1 2017-04-19

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

A simple physics approach has allowed to intercompare the major features of PWR's [pressurized water reactors], with standard oxide or Inert Matrix Fuel, and fast neutron reactors, in iso-generating or burner mode, when recycling Pu and TRU.

OBS

burner mode. An operating mode for a nuclear reactor, especially a breeder, in which the conversion factor is lower than 1.

Key term(s)
  • reactor in iso generating mode
  • iso generating reactor

French

Domaine(s)
  • Réacteurs nucléaires de fission
DEF

Réacteur nucléaire produisant autant de combustible fissile qu'il en consomme.

CONT

Dans le cas d'un réacteur iso-générateur, la masse de matière fissile est constante dans le cœur, et seule la matière fertile diminue. Ainsi, chaque fission qui a lieu dans le réacteur provient d'un noyau de fertile (non fissile) qui aura auparavant capturé un neutron pour produire un noyau fissile. On ne consomme donc que de la matière fertile.

Key term(s)
  • réacteur iso générateur

Subject field(s)
  • Space Exploration Equipment and Tools
CONT

The Pistol Grip Tool(PGT) is the primary power tool for the Hubble Space Telescope and International Space Station operations. [This] self-contained, computer controlled, and battery powered 3/8 inch drive pistol grip style power tool [is] programmable on-orbit or on the ground for speed, torque, and revolutions settings. [It] interfaces with many types of mechanisms and fastener types. [It is an] Integral Multiple Setting Torque Limiter(MTL) [and has] an EVA changeable battery[, ] a separate manual ratchet and motorized torque modes[, ] a LED Matrix readout of tool functions. [It's] modular construction [allows] for ease of new technology integration. Torque settings range from 0. 7 to 25. 0 ft-lbs in motorized mode, and up to 38. 00 fr-lbs in manual mode. The MTL torque setting range from 2. 0 to 40. 0 fr-lbs and above. Speed settings range from 5 to 60 RPM. Revolutions count settings range from 0. 01 to 999 turns. The battery [is] sized to provide full 25. 0 ft-lb torque on 80 fasteners.

OBS

pistol grip tool; PGT: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Équipement et outillage d'exploration spatiale
OBS

pistolet de serrage programmable; PGT : terme et abréviation uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Subject field(s)
  • Information Processing (Informatics)
  • Television (Radioelectricity)
  • Audiovisual Techniques and Equipment
CONT

Surround modes for music. Many surround decoders provide processing modes other than Dolby Surround, variously called "Hall, ""Stadium, ""Jazz Club, "etc. These attempt to recreate the effect of hearing music performed in their namesake environments. A "Matrix" mode may also be provided to give either mono or conventional stereo programs added spatial dimensionality.

French

Domaine(s)
  • Traitement de l'information (Informatique)
  • Télévision (Radioélectricité)
  • Audiovisuel (techniques et équipement)
CONT

[Dolby Surround Pro Logic II]. Un mode matrix optionnel permet de produire du son enveloppant à partir d'une source monophonique.

English

Subject field(s)
  • Biological Sciences
  • Geology
CONT

Two fundamentally different modes of biomineralization are summarized by Lowenstam and Weiner [1989]. One is called biologically induced mineralization(BIM), in which an organism modifies its local microenvironment creating conditions suitable for the chemical precipitation of extracellular mineral phases. The second mode is called boundary organized biomineralization(BOB), in which inorganic particles are grown within or on some organic matrix produced by the organism.

Key term(s)
  • biomineralisation

French

Domaine(s)
  • Sciences biologiques
  • Géologie
DEF

Emploi de bactéries calcifiantes pulvérisées sur la pierre dégradée d'un édifice, en vue de constituer une couche protectrice de calcin.
