Record 1 2012-02-22

English

Subject field(s)
  • Atmospheric Physics
  • Air Pollution
DEF

Air (relatively) devoid of solid, liquid or gaseous pollutant materials.

CONT

The composition of air is variable with respect to several of its components(e. g., CH4, CO2, H2O) so "pure" air has no precise meaning; it is commonly considered to be air which is free of dust, [hydrometeors, ] aerosols, and reactive gaseous contaminants of anthropogenic origin [such as industrial effluents].... Relative clean air which is free of most reactive anthropogenic pollution(NO, NO2, SO2, non-methane hydrocarbons, etc.), often used as a reference sample in the calibration and operation of instruments, is purchased under the designation of zero air.

CONT

[The] so-called "pure" air is a mixture of gases containing about 78 percent nitrogen; 21 percent oxygen; less than 1 percent of carbon dioxide, argon, and other inert gases; and varying amounts of water vapor.

OBS

air: The mixture of gases comprising the earth’s atmosphere.

French

Domaine(s)
  • Physique de l'atmosphère
  • Pollution de l'air
DEF

Air (relativement) exempt de matières polluantes solides, liquides ou gazeuses.

CONT

L'air est un mélange de gaz constituant l'atmosphère qui entoure la terre. L'air pur est composé de 21 % d'oxygène et de 78 % d'azote par volume, en plus de quantités infimes d'autres gaz comme l'argon, le gaz carbonique et la vapeur d'eau.

Record 2 2005-06-01

English

Subject field(s)
  • Fatty Substances (Food)
  • Slaughterhouses
CONT

Bleachable fancy tallow(BFT) is made from a mixture of inedible fat sources collected from butcher shops, grocery stores, and meat processing plants. BFT is great for increasing the energy value and palatability in animal feeds. The tallow can be further processed and segregated into individual fatty acids and glycerine which are then used to manufacture other products such as lubricants and dust suppressants. BFT has a high composition of saturated fatty acids and can have up to four per cent free fatty acids.

French

Domaine(s)
  • Corps gras (Ind. de l'aliment.)
  • Abattoirs
CONT

Les usages dépendent de la catégorie et de la qualité des graisses, comme le suif de qualité supérieure blanchissable, la graisse blanche de choix, le suif comestible, les graisses animales de catégorie fourragère, les graisses de volaille et le suif et la graisse jaune de catégorie A ou B.

OBS

GRAS: Mélange de gras animal, d'huile végétale de choix (huile de coconut) et de suif de qualité supérieure.

Subject field(s)
  • Space Physics
  • Gravity (Physics)
CONT

STEP : Satellite Test of the Equivalence Principle. Worden and Everitt have proposed to carry out an improved version of Galileo's Leaning Tower of Pisa experiment, by placing masses of different composition inside a satellite orbiting the Earth to obtain a long duration of free fall. Very high positional sensitivity can be achieved by cooling the experiment to 1. 8 K and using SQUIDs to detect in current changes in magnetic pickup coils. The test masses of different materials and the position measuring equipment are placed inside the satellite and micro Newton thrusters are used to cancel the small accelerations of the satellite due to air drag, radiation pressure and the solar wind which could couple to masses.

Record 4 2001-02-28

English

Subject field(s)
  • Thermal Insulation
  • Building Insulation and Acoustical Design
CONT

Tank top insulation. A thermal calculation should be performed to determine the proper insulation thickness to ensure either personnel protection or process control. Where the insulation thickness exceeds 3", a multiple layer system is recommended. Composition : Basalt wood and organic binder which is non-combustible and asbestos free.

French

Domaine(s)
  • Isolation thermique
  • Isolation et acoustique architecturale
CONT

[...] on remplit les murs creux en construction de laine de basalte ou laine de roche à dominante basaltique.

CONT

L'isolation très poussée en laine de basalte ignifugée de 35mm d'épaisseur, fournit une excellente capacité thermique à la cheminée.

Subject field(s)
  • Airport Runways and Areas
  • Signalling and Illumination (Air Transport)
CONT

Specification of glass beads. The primary characteristics of retro-reflective beads(glass spheres) to be considered in selection for aerodrome markings are composition, index of refraction, gradation, and imperfections. Glass spheres which are lead free, uncoated, with a refractive index of 1. 90 or greater, have size gradation between 0. 40 and 1. 30 mm diameter, and with less than 33 per cent imperfections have been found best for aerodrome markings.

French

Domaine(s)
  • Pistes et aires d'aéroport
  • Signalisation (Transport aérien)
CONT

Caractéristiques des grains de verre. Les principales caractéristiques des grains rétroréfléchissants (billes de verre) dont il faut tenir compte en vue de leur utilisation pour les marques d'aérodrome sont la composition, l'indice de réfraction, le calibre et les imperfections. On a constaté qu'il était préférable, pour les marques d'aérodrome, d'utiliser des billes de verre exemptes de plomb, sans enduit, ayant un indice de réfraction égal ou supérieur à 1,90, de 0,40 à 1,30 mm de diamètre et comportant moins de 33% d'imperfections.

  • Painting (Arts)
DEF

Colour woodcuts, of scenes from low life, which combined great boldness of invention with masterly technical perfection ..., new motifs and new colour schemes ....

CONT

Degas's interest in the Japanese print was a more purely abstract interest in the style of composition, the freedom of foreshortening, the close-up, the keyhole view, the free outline and the asymmetry.

French

Domaine(s)
  • Peinture (Arts)
DEF

art populaire (...) le portrait, la nature morte, ou la scène de la vie quotidienne, dont l'élément essentiel était la ligne, qui, avec sa direction et sa puissance, non seulement déterminant le contour, mais était aussi capable d'exprimer le volume, en termes abstraits.

CONT

Dès 1854, les contacts reprennent avec le Japon et les artistes français découvrent alors les grands maîtres de l'estampe japonaise.
