Abstract: L'invention concerne un procédé pour assembler des cartes génomiques de l'ADN d'un organisme ou des parties de celui-ci. On fournit une bibliothèque de l'ADN d'un organisme dans laquelle on trouve plusieurs clones comportant des séquences ou des segments génomiques individuels. On crée des représentations du génome, et l'on génère des informations sur la séquence d'acides nucléiques à partir de ces représentations. On analyse les informations relatives aux séquences pour déterminer le chevauchement des clones à partir d'une représentation. On combine le chevauchement des clones et les informations sur la séquence provenant des représentations différentes pour assembler une carte génomique de l'organisme. Une fois la carte génomique obtenue, les informations sur la séquence génomique provenant de différents individus peuvent être appliquées à la carte et comparées les unes avec les autres afin d'identifier les polymorphismes d'un nucléotide unique. On peut détecter ces polymorphismes de nucléotide unique et quantifier les allèles en effectuant (1) une amplification PCR globale qui crée une représentation du génome et (2) une réaction de détection de ligature, les produits de la ligature étant captées par hybridation sur un support.

Patent CA-2377604-A1 (CA)
Inventor: VAN DER GEEST MARIAN
IPC: H01M8/04
Filed: 2000-06-27
Abstract: A method and apparatus increase the temperature of a fuel cell via reactant starvation at one or both electrodes.  Reactant starvation at an electrode results in an increased overvoltage at the electrode and hence increased internal heat generation under load. Further, starvation techniques may be used to prevent poisoning of electrode catalysts, a potential problem that is aggravated at lower temperatures. Starvation conditions can be prolonged or intermittent and can be obtained, for example, by suitably reducing the supply rate of a reactant or by operating the fuel cell at sufficiently high current density so as to consume reactant faster than it is supplied. The method can allow for some generation of useful power by the fuel cell during start-up. The method is particularly suitable for starting up a solid polymer electrolyte fuel cell from temperatures below 0°C.
