    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.

    The Causal Interpretation of Conformally Coupled Scalar Field Quantum Cosmology (2000)
    Springer
    General relativity and gravitation 32 (2000), S. 15-39

    ISSN: 1572-9532
    Keywords: Wheeler–DeWitt equation

    Topics: Physics
    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.

    SMART Cables Observing the Oceans and Earth (2022)
    In:  Marine Technology Society Journal
    Details
    Publication Date: 2022-11-14
    Description: The Joint Task Force, Science Monitoring And Reliable Telecommunications (SMART) Subsea Cables is working to integrate environmental sensors (temperature, pressure, seismic acceleration) into submarine telecommunications cables. This will support climate and ocean observation, sea-level monitoring, observations of Earth structure, tsunami and earthquake early warning, and disaster risk reduction. Recent advances include regional SMART pilot systems that are the initial steps to trans-ocean and global implementation. Building on the OceanObs’19 conference and community white paper (https://doi.org/10.3389/ fmars.2019.00424), this paper presents an overview of the initiative and a description of ongoing projects including: InSea wet demonstration project off Sicily; Vanuatu and New Caledonia; Indonesia; CAM-2 ring system connecting the Portuguese mainland, Azores, and Madeira; New Zealand; and Antarctica. In addition to the diverse scientific and societal benefits, the telecommunications industry’s mission of societal connectivity will also benefit because environmental awareness improves both individual cable system integrity and the resilience of the overall global communications network.

    SMART Subsea Cables for Observing the Earth and Ocean, Mitigating Environmental Hazards, and Supporting the Blue Economy (2022)
    In:  Frontiers in Earth Science
    Details
    Publication Date: 2022-02-18
    Description: The Joint Task Force, Science Monitoring And Reliable Telecommunications (JTF SMART) Subsea Cables, is working to integrate environmental sensors for ocean bottom temperature, pressure, and seismic acceleration into submarine telecommunications cables. The purpose of SMART Cables is to support climate and ocean observation, sea level monitoring, observations of Earth structure, and tsunami and earthquake early warning and disaster risk reduction, including hazard quantification. Recent advances include regional SMART pilot systems that are the first steps to trans-ocean and global implementation. Examples of pilots include: InSEA wet demonstration project off Sicily at the European Multidisciplinary Seafloor and water column Observatory Western Ionian Facility; New Caledonia and Vanuatu; French Polynesia Natitua South system connecting Tahiti to Tubaui to the south; Indonesia starting with short pilot systems working toward systems for the Sumatra-Java megathrust zone; and the CAM-2 ring system connecting Lisbon, Azores, and Madeira. This paper describes observing system simulations for these and other regions. Funding reflects a blend of government, development bank, philanthropic foundation, and commercial contributions. In addition to notable scientific and societal benefits, the telecommunications enterprise’s mission of global connectivity will benefit directly, as environmental awareness improves both the integrity of individual cable systems as well as the resilience of the overall global communications network. SMART cables support the outcomes of a predicted, safe, and transparent ocean as envisioned by the UN Decade of Ocean Science for Sustainable Development and the Blue Economy. As a continuation of the OceanObs’19 conference and community white paper (Howe et al., 2019, doi: 10.3389/fmars.2019.00424), an overview of the SMART programme and a description of the status of ongoing projects are given.
