Réseau National De Mesures De La Radioactivité De L'environnement
The term réseau derives from a French word meaning "network". It may mean: *a network of fine lines on a glass plate, used in photographic telescopes to make a corresponding network on photographs of the stars: see Réseau plate *a system of weather stations under a single agency, or cooperating on common goals *an intelligence network as used by John Le Carré, in ''Tinker, Tailor, Soldier, Spy'', chapter 11. *the net in bobbin lace Bobbin lace is a lace textile made by braiding and twisting lengths of thread, which are wound on bobbins to manage them. As the work progresses, the weaving is held in place with pins set in a lace pillow, the placement of the pins usually de ... * SNCF TGV Réseau {{Disambiguation ...

Réseau Plate
A Réseau plate is a transparent sheet of glass or plastic engraved with a grid of crosshatches called fiducial markers. It was commonly used in film cameras (before the advent of digital media) for scientific and technical photography. The plate is placed at the focal plane of the camera just in front of the film. When the frame is exposed the fiducial markers scatter incoming light, creating a permanent shadow on the negative. The fiducial markers on a Réseau plate are sometimes called reticles. The Latin root of fiducial means ''trust, confidence''; fiducial markers are trustworthy reference points. The Latin root of reticle means ''small meshwork bag, small net''; a grid of reticles has a net-like appearance. Purpose and function If the film negative is properly printed the fiducial markers will be evenly spaced on the positive image. Uneven spacing reveals that the image has been distorted. Identical spacing on adjacent images (e.g. from a series of aerial photos) ensures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer for ...

Bobbin Lace Ground
Bobbin lace ground is the regular small mesh filling the open spaces of continuous bobbin lace. Other names for bobbin lace ground are net or réseau (French for network). The precise course of the threads and the resultant shape of the ground are an important diagnostic feature in lace identification, as different lace styles use different grounds. Point ground Point ground is also known as ''fond simple'' or simple ground, ''fond clair'', Lille, point, net ground or Bucks Point ground. Grid angle: 52°-70°, usually 60°, never 45° It is a simple hexagonal mesh. Each stitch uses a pair of threads on each side. Some threads travel diagonally, and some move to left, then back to right, from stitch to stitch. This ground is used in Bucks Point, Lille, Chantilly, and blonde lace.

Bobbin Lace
Bobbin lace is a lace textile made by braiding and twisting lengths of thread, which are wound on bobbins to manage them. As the work progresses, the weaving is held in place with pins set in a lace pillow, the placement of the pins usually determined by a pattern or pricking pinned on the pillow. Bobbin lace is also known as pillow lace, because it was worked on a pillow, and bone lace, because early bobbins were made of bone or ivory. Bobbin lace is one of the two major categories of handmade laces, the other being needle lace, derived from earlier cutwork and reticella. Origin A will of 1493 by the Milanese Sforza family mentions lace created with twelve bobbins. There are two books that represent the early known pattern descriptions for bobbin lace, ''Le Pompe'' from Venice and ''Nüw Modelbuch'' from Zürich. Bobbin lace evolved from passementerie or braid-making in 16th-century Italy. Genoa was famous for its braids, hence it is not surprising to find bobbin lace de ...
