Abstract: Electrophoresis is performed in buffers which exhibit both substantial bufferingcapacity and low electrical conductivity, permitting the separations to be performed at high field strengths without loss of resolution. Four classes of buffering agents are cited as examples: (1) buffering agents with a small number of charged groups per molecule; (2) carrier ampholytes fractionated to a narrow isoelectric point range; (3) low molecular weight buffering ampholytes with an isoelectric point which is close in value to one of the pK values of the ampholyte; and (4) high molecular weight buffering ampholytes in which the acidic and basic groups have the same or very close pK values. These buffering agents are of particular interest in capillary electrophoresis.

Abstract: Système de création d'instructions téléchargeables dans une plate-forme d'applications, par exemple une plate-forme d'applications vocales. Les instructions sont définies par une multitude d'opérations qui dépendent de certains paramètres et sont appelées des blocs; l'ensemble des blocs liés entre eux détermine la topologie des applications. Avant d'entrer les paramètres, on procède à la validation du squelette des blocs liés; si le test de validité est réussi, les paramètres sont saisis. Lorsque tous les paramètres ont été entrés afin de définir l'ensemble du système, on procède à une simulation, y compris une simulation vocale. Cette simulation peut être effectuée sur une plate-forme de développement ou d'applications vocales. Un bloc peut définir un appel à un sous-programme extérieur. Le système défini à l'origine est automatiquement converti en instructions téléchargeables. Celles-ci comprennent également l'appel au sous-programme extérieur; ce sous-programme peut ainsi être appelé au cours d'une opération en ligne. Il est aussi possible d'inclure des blocs de remplacement temporaraires qui permettent d'intégrer du code C dans le code téléchargeable.
