Qu’il soit assertif, interrogatif ou autre, l’énoncé est constitué de syntagmes qui peuvent être définis comme un ensemble d’éléments linguistiques susceptibles de se combiner afin de former une suite cohérente de morphèmes pour déboucher sur une uni [...]
Malgré les multiples réformes qu’a connues le système éducatif béninois et la mise en oeuvre de l’Approche par Compétence, les professeurs d’Anglais dans les établissements d’Enseignement Secondaire Technique continuent d’utiliser l’Approche par Ob [...]
The cooling for air conditioning or foodstuff refrigeration is ensured in most cases with compression refrigeration machines which are high electrical energy consumers. They are responsible of much greenhouse effects, especially when CFCs, are involv [...]

In this paper, a new geometric quantity, the trace-free horizon- tal Ricci tensor of a Finsler manifold is proposed. The conformal changes of this tensor, relatively to the conformal deformations of Finsler metrics when an Ehresmann form varies, are [...]

In this paper, a new Ricci flow is canonically introduced in Finsler Geometry and, under the variance of Finsler-Ehresmann form, conformal changes of Finsler metrics are studied. Some existence conditions of this Finslerian Ricci flow on a compact ma [...]

Given a Finsler manifold (M, F ), it is proved that the first eigenvalue of the Finslerian p-Laplacian is bounded above by a constant depending on p, the dimension of M , the Busemann-Hausdorff volume and the reversibility constant of (M, F ). For [...]

The biguanides [HN=C(NR1R2)-NH-C(NR3R4)= NH] constitute an important family of molecules used as drugs in the treatment of diabetes. The five nitrogen atoms are potential coordination sites since they each carry a free electron pair. In the state o [...]
