Historically, smelling salts contained ammonium carbonate and perfume; modern preparations typically consist of ammonia dissolved in water and ethanol, sometimes infused with a scented oil, such as eucalyptus. The salts release ammonia gas that irritates the nose and lung membranes, triggering an inhalation reflex, which prompts the muscles that control breathing to work faster and helps restore oxygen flow to the brain and body.  6, record 1, English, - smelling%20salts

The highly-efficient and economically-feasible technology for bitumen recovery from US oil sands using a water extraction approach was developed at the end of the last century. This water-based bitumen extraction process has been optimized based on observations and analysis of microscopic mechanisms of bitumen release from oil sands and the bitumen transfer to a froth product as well as measurements of interfacial properties of bitumen. The wetting mechanisms that occur in the diluent-assisted water-based processing of US oil sands include bitumen film rupture and recession on sand grains and bitumen transfer to nucleated and injected gas bubbles.  2, record 14, English, - water%2Dbased%20bitumen%20extraction%20process

L'extraction du bitume se fait par le procédé à l'eau chaude, mis au point par Karl Clark en 1929. Ce procédé consiste à placer le sable bitumineux dans d'énormes tambours rotatifs et à le mélanger avec de l'eau chaude et de la vapeur. Le bitume se sépare du sable et se lie aux bulles d'air. Le tout est tamisé et déposé dans des contenants de formes coniques permettant la séparation. Le bitume lié à l'air est récolté sous forme de mousse, contenant 65% de pétrole, 25% d'eau et 10% de solides. Après avoir mélangé le tout à l'aide de grosses centrifugeuses, trois couches sont observées. Les grosses particules de sables se déposent au fond, qui sont pompés vers une décharge et utilisés dans la construction des digues. La couche intermédiaire est constituée d'un mélange d'eau, de petites particules de bitumes et quelques minéraux, qu'on appelle mixtes. Cette eau intermédiaire est retirée et pompée afin de les réutiliser dans le processus d'extraction. Enfin, le bitume flotte à la surface, ce qui permet de le récupérer avec un pourcentage de 88 à 95%.  3, record 14, French, - proc%C3%A9d%C3%A9%20%C3%A0%20l%27eau%20chaude%20pour%20l%27extraction%20du%20bitume

High-pressure testing results of a prototype TVC sector indicate it can help meet increased performance requirements while reducing overall emissions.

It is used because bending conduit results in too much friction loss in the movement of the cable in the conduit. There are two types of pulley elbows.

L'air, qui se trouve directement au contact du sol, tend donc à s'élever le long de la pente tandis que l'air libre s'affaisse : c'est la brise montante. La nuit au contraire, le sol refroidit par rayonnement l'air qui se trouve en contact avec lui. Cet air devenu plus lourd s'écoule le long de la pente : c'est la brise descendante.
