CONT

Marine biofilm : how quickly does it form? Immediately, when a surface is immersed in the sea, a conditioning film of organic molecules forms. This begins after a few seconds of immersion and is considered as molecular fouling. In the hours and days that follow, bacteria colonise the surface and micro colonies occur. These colonies spread outwards and upwards to form irregular structures. At this stage other microfouling appear, e. g. microalgae and fungi... The biofilm then matures and new species enter and grow, organic and inorganic debris is incorporated and solute gradients develop leading to a special heterogeneity. At this point three things can occur : The biofilm may slough off due the hydrodynamics of the environment; Organisms may begin to graze on the biofilm; Larger organisms such as algae and molluscs may establish on it, this is macrofouling.

Key term(s)
  • micro fouling
  • micro-fouling

Domaine(s)
  • Microbiologie et parasitologie
  • Biologie marine
  • Entretien des navires
CONT

Les salissures sont surtout d'ordre biologique et l'on parle de biosalissures. Selon la taille des organismes on distingue les : -microsalissures : bactéries et algues unicellulaires, larves, [...] qui forment le «voile biologique»; - macrosalissures : algues pluricellulaires, mollusques fixés, larves, vers, crustacés (balanes et autres), qui ne s'installent que lorsque le substrat est déjà colonisé par les microsalissures.

OBS

microsalissure : terme généralement employé au pluriel.

Key term(s)
  • microsalissures marines

Record 4 2001-10-09

English

Subject field(s)
  • Orbital Stations
CONT

Most LTMPF [Low-Temperature Microgravity Physics Facility] experiments are sensitive to random vibrations, charged particles, and stray magnetic fields.... A passive vibration isolation system attenuates higher frequency(>1Hz) vibration inputs from the ISS [International Space Station] to below 500 micro g rms. Several layers of magnetic shielding are built into the instrument probe to protect the experiments from on-orbit variations in the magnetic field environment.

OBS

passive vibration isolation system: term officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Stations orbitales
OBS

système passif d'isolation contre les vibrations : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Record 5 2001-07-04

English

Subject field(s)
  • Spacecraft
CONT

Inside an orbiting spacecraft a "microgravity" environment exists in which the acceleration of objects and persons relative to their surroundings is reduced to the level of micro g's...

OBS

Even in a gravity gradient attitude, accelerations caused by crew movements, equipment operations, and occasional thruster firings can disrupt the quiescent low-gravity environment and may affect microgravity science experiments. Accelerations at particular frequencies may interrupt one type of experiment but have no effect on others. These accelerations are measured at fractions of Earth’s gravity; for instance, 10~ g is equal to 1/100,000 of the gravity on Earth.

OBS

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

PHR

Vibratory microgravity environment.

French

Domaine(s)
  • Engins spatiaux
CONT

Un environnement en microgravité offre aux scientifiques une occasion unique de contrôler les phénomènes liés à la gravité. De plus, en microgravité, le traitement sans contenant peut être pratiqué sur de plus gros échantillons, car les force acoustiques et électromagnétiques utilisées pour manipuler ne sont pas dominées par la gravité.

OBS

environnement en microgravité : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).
