Electrocarboxylation of chloroacetonitrile mediated by electrogenerated cobalt(I) phenanthroline [PDF]

open access: yes, 2010
The electrocarboxylation of chloroacetonitrilemediated by [Co(II)(phen)3]2+ has been investigated. Cyclic voltammetry studies of [Co(II)(phen)3]2+ have shown that [Co(I)(phen)3]+, an 18 electron complex, activates chloroacetonitrile by an oxidative ...

Improved Incremental Randomized Delaunay Triangulation [PDF]

open access: yes, 1997
We propose a new data structure to compute the Delaunay triangulation of a set of points in the plane. It combines good worst case complexity, fast behavior on real data, and small memory occupation.

Postures épistémiques d’enseignants-tuteurs en contexte d’apprentissage par problèmes (APP) : les cas de la médecine et du génie

open access: yesRevue Internationale de Pédagogie de l’Enseignement Supérieur, 2016
Major pedagogical innovations implemented by some programs lead teachers to a change of role (Bédard & Béchard, 2009). We hypothesized that their ability to align their interventions with pedagogical precepts of innovation is largely dependent on their ...
