Abstract: L'invention concerne un procédé de dosage enzymatique multiplexé ainsi qu'un ensemble substrats servant à l'exécution du procédé, lequel consiste à effectuer plusieurs réactions enzymatiques, en présence de plusieurs substrats d'enzymes, dans des conditions efficaces pour convertir un substrat d'enzyme en un produit correspondant, le produit de chaque substrat et le substrat possédant des caractéristiques de séparation différentes l'un de l'autre, et différentes des autres substrats et de leurs produits correspondants. Après que l'on ait exécuté ces réactions, soit de manière séparée soit de manière combinée, on sépare les substrats et les produits de ces réactions, dans un seul milieu de séparation. Pour chaque produit et substrat séparés, on détecte une caractéristique de séparation permettant d'identifier ce produit et ce substrat, de même qu'un signal relatif à la quantité de produit et de substrat. A partir de ces éléments détectés, on peut déterminer la quantité de substrat convertie en produit correspondant, dans chacune des réactions.
Patent CA-2420155-A1 (CA)
Inventor: DESROSIERS RONALD ROGER
IPC: B22D11/06
Filed: 2001-09-14
Abstract: A process of casting a molten metal to form a cast metal strip ingot while controlling heat flux from the cast metal. The process comprises continuously supplying molten metal to a casting cavity formed between a pair of moving continuous casting surfaces that withdraw heat from the molten metal to cause metal solidification, and continuously withdrawing a resulting cast strip ingot from the casting cavity. A gas (e.g. air) containing water vapour substantially without liquid water (i.e. a moist gas) is supplied to the inlet of the casting cavity in a region containing the meniscus formed where the molten metal first contacts the casting surfaces. The moist gas has the effect of adjusting the heat withdrawal by the casting surfaces to minimize surface defects in the cast strip ingot and to avoid undesired distortion of the casting cavity. Furthermore, in those cases where a parting agent is applied to the casting surfaces, the amount of parting agent applied to the casting surfaces may be reduced. The invention also relates to equipment provided for the delivery and dewpoint control of the moist gas.
