A large-scale preparation of the two-subunit protein complex (QPs) that converts succinate dehydrogenase into succinate-ubiquinone reductase from cytochrome 6-c, particles is achieved by a procedure involving Triton X100 solubilization and calcium phosphate column chromatography at different pH values. The isolated two-subunit QPs contains 25 nmol of cytochrome basofmg of protein and is able to...

5 N otre profession a connu d'énormes change-ments depuis son lancement au Canada il y a quelque 50 ans. Depuis la création d'un cours pour les inhalothérapeutes au Queen Mary Veterans Hospital et la fondation du département technique d'inhalothérapie à l'Hôpital Royal Victoria de Montréal, au Québec, la prestation de soins respiratoires compétents a continué d'évoluer dans les hôpitaux et les ...

In this paper, we provide a combinatorial definition of the Universal Grassmannian order (or the Grassmannian Bruhat order) of Bergeron and Sottile. This defines the order in terms of inversions, and thus the order can be viewed as a generalization of the weak order for Coxeter groups. Finally, we use this understanding of the order to analyze the generating function of the number of elements a...
