Couche caractérisée par la décroissance progressive de la taille des éléments, qui passe de grossière à la base à fine au sommet de la couche (granodécroissance).

CONT

Les minéraux métallifères se rencontrent préférentiellement sous forme de ciment s'insinuant entre les grains de sable détritiques. Dans les grès massifs, cela se traduira par des bulles ou taches de sulfures disséminées, alors que dans les parties inférieures plus poreuses des couches granoclassées, on observera des concentrations de sulfures plus étendues.

Record 7 2001-09-14

English

Subject field(s)
  • Drainage and Irrigation (Agric.)
CONT

Drip Irrigation.... Water is delivered in small quantities under low pressure directly to... the root zone of the plants. You’ll need 1/2 inch polyethylene header pipe, and a roll of thin tape-like porous tubing. The header pipe connects to a garden hose and routes water through the garden. The pipe is placed either down the center or along one end of the garden. Small puncture holes are then made with a screwdriver into the header pipe at intervals corresponding to garden row. Eight-to ten-inch pieces of rubber connecting hose are then inserted into these holes. The other end of the connecting hose attaches to a length of porous tape. This tape is rolled out along each vegetable bed and cut to the same length as the row. Then end of the tape is then crimped to prevent water loss when the system is in use. Porous irrigation tape is best placed about three to four inches away from the base of the plants.

French

Domaine(s)

CONT

Les rampes aplatissables sont appelées des gaines qui peuvent être simples ou doubles. On distingue divers types de gaines : - gaines perforées [...] - gaines poreuses : la paroi extérieure, composée de fibres «non tissées», laisse suinter l'eau à travers des pores de quelques micromètres. Gaines perforées et poreuses ne sont utilisables qu'à de faibles pressions et ne peuvent convenir que pour des cultures annuelles (maraîchage, fleurs) en terrain plat.

Record 10 1993-07-14

English

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
  • Biomass Energy
CONT

Grate fired combustors. Grate-fired systems include both pile burners and spreader-stokers. Pile burners include the old-fashioned Dutch ovens(or Dietrich cells for bagasse and coffee grounds), Wellons cells, Lanb-Cargate wet cell or gasifier burners, and inclined grate systems. Spreader-stokers are distinguished by their feed mechanism, typically a windswept or pneumatic spout or paddle wheel located above the grate and the thin bed of fuel on the grate. The stoker mechanism spreads the fuel more or less uniformly across the grate. Grate fired systems may use flat or sloping grates, with inclined grates being the most severely sloping grate systems. Grates may be stationary or moving. They may be air cooled or water cooled. Ash removal from grates may be accomplished by moving arms, steam or air blowing systems, grate moving, or hand raking. Grate fired units may be refractory lined or waterwall furnaces, depending upon vendor and purpose.

Record 11 1993-07-12

English

Subject field(s)
  • Solid Fuel Heating
CONT

... the spreader stoker projects fuel into the furnace over the fire with a uniform spreading action, permitting suspension burning of the fine fuel particles. The heavier pieces, that cannot be supported in the gas flow, fall to the grate for combustion in a thin fast-burning bed.

CONT

Spreader stokers ... feed coal by rotors or paddles....

CONT

Grates for spreader stokers may be of several types. ... continuous ash discharging grate, such as the traveling grate, [the reciprocating and vibrating grates;] ... stationary grate and dumping grate ....

OBS

Stokers are [also] classified according to the method of feeding fuel to the furnace, as 1. spreader, 2. underfeed, 3. chain grate or traveling grate, and 4. vibrating grate.

French

Domaine(s)
  • Chauffage aux combustibles solides
DEF

(...) appareil [dans lequel] le combustible est projeté sur la grille au moyen d'un dispositif approprié, la grille étant situé à l'intérieur de la chaudière. L'air comburant primaire est soufflé sous la grille. Le décrassage a lieu en général manuellement.

CONT

Brûleurs à projection. (...) Ils comprennent, en outre: la grille fixe ou tournante à barreaux fixes ou oscillants, les dispositifs de distribution du charbon, l'organe de lancement du combustible (pelleteur oscillant ou rotatif à commande mécanique ou pneumatique), le mécanisme de commande et de réglage d'allure, le moteur d'entraînement du mécanisme.

OBS

En anglais, on parle surtout du dispositif d'alimentation en combustible du foyer (stoker); en français, on parle plutôt de l'endroit où a lieu la combustion (foyer) et où est logé l'organe de combustion qu'est la grille. Il est à noter que selon le LAROG, le foyer "est à la fois un lieu et un ensemble d'appareils ou d'organes (...)". MOMON semble donc utiliser foyer et grille au sens de dispositif. Ainsi grille semble parfois désigner la partie (grate) ou dispositif d'alimentation du foyer ou le tout (stoker).

Record 12 1990-01-15

English

Subject field(s)
  • Biological Sciences
DEF

The growing of microorganisms, often fungi, on a solid material rather than in a liquid medium.

CONT

The fermentation of solid substrates such as starchy or cellulosic materials can be approached in two different ways. The solid material can be suspended in an aqueous medium. A general problem with such preparations is that gelatinization of the starches, etc. can generate highly viscous broths causing poor mixing and O2 transfer at dry weight concentrations higher than 2% w/v. There is also the obvious diseconomy of adding so much water to the substrate only to remove it from the product. Alternatively, then, the problem is approached through ’solid state fermentation’, the growth of microorganisms on solid materials without the presence of free liquid.

OBS

Such techniques can be divided into two basic types :thin layer and deep bed. In the former system, the organisms are grown on the surface of the substrate, which is spread on shallow trays about 2-4 cm deep; the trays are incubated in air-conditioned rooms or cabinets. The simplest deep bed systems consist of heaps of substrate that may be stirred periodically by hand. More sophisticated, fully automated systems include rotating drums, conveyor belt systems, which pass through air-conditioned tunnels, or deep tanks through which air is blown. The substrates used are generally based on wheat bran.

French

Domaine(s)
  • Sciences biologiques
CONT

La production de P.O.U. [peut s'effectuer par la] fermentation en milieu solide. (...) Il s'agit en l'occurrence d'ensemencer à l'aide d'une suspension de levures (Pichia burtonii, Candida tropicalis ...) ou de spores de champignons filamenteux (Aspergillus niger, Rhizopus sp. ...) amylolytiques, du manioc ou du mais réduits en semoule d'une granulométrie de quelques mm, et de favoriser la croissance microbienne. Pour cela on assure simultanément une humidité d'environ 50 à 60 %, grâce à une solution de sulfate d'ammonium, de phosphate de potassium et d'urée et un courant d'air humide. (...) La croissance des micro-organismes, qui dure une trentaine d'heures s'effectue au milieu non stérile et se traduit par l'envahissement du substrat par le mycélium (ensemble des cellules fongiques); on a donc un enrichissement global du milieu en protéines nobles, riches en acides aminés essentiels et en particulier en lysine.
