    Description / Table of Contents: Résumé  23 patients avec épiphysiolyse fémorale supérieure de l’adolescent ont été traités utilisant une ostéotomie modifiée avec résection trapézo sous-capitale. Tous les déplacement ont été de plus de 60 degrees. La moyenne de la période d’étude a été de 70 mois (54–93 mois). On a retrouvé un resultat excellent ou bon en 18 hanches, passable en 1, et médiocre en 4 hanches. La nécrose céphalique s’est developpée en 3 hancles et la chondrolyse en 2.
    Notes: Abstract  Twenty-three patients with chronic or acute to chronic slip of the capital femoral epiphysis were treated using a modified trapezoid osteotomy of the femoral neck. All slips were greater than 60°. After a follow-up period of 70 (54–93) months, the results were excellent or good in 18 hips, fair in 1, and poor in 4 hips. Avascular necrosis developed in 3 hips, and chondrolysis in 2.

    Notes: Abstract We apply the causal interpretation of quantum mechanics to homogeneous and isotropic quantum cosmology, where the source of the gravitational field is a conformally coupled scalar field, and the maximally symmetric hypersurfaces have positive curvature. In order to simplify the system of coupled equations studied and study the quantum behavior near the singularity, we restricted ourselves to the cases where the scale factor is small. In this case, the general solution of the Wheeler–DeWitt equation is a discrete superposition of Hermitian polynomials multiplied by complex exponentials. Superpositions with up to two parcels are studied, and the phase diagrams of their corresponding Bohmian trajectories are analyzed in detail. Nonsingular periodic quantum solutions are found. We also find that singular quantum solutions present an inflationary era in the begining of the Universe. Numerical calculations indicates that these results remain valid for general superpositions.
