    In the complex anion of the title compound, Na[Re(C10H8N2O2S2)O]·H2O, the Re atom adopts a square-pyramidal coordination, in which the Re=O bond is apical and the S,N,N,S-tetradentate ligand spans the four basal sites. The Na+ counter-ion is octahedrally surrounded by one S and five O atoms

    The title compound, (C24H20P)[Re(C10H9N3O2S)O], contains well separated square-pyramidal [OReL]- complex anions (L is the deprotonated N-(2-aminophenyl)-2-(mercaptomethylcarbonylamino)ethanamide ligand) and tetrahedral [(C6H5)4P]+ cations. In the anion, the Re=O bond is oriented along the apical direction and the four basal sites are occupied by one S- and three N-atom donors of the tetradentate L4- ligand

    Histoire du canal Saint-Georges (Port-Menier, Ăźle d’Anticosti) et perspectives : la valorisation du patrimoine culturel par l’amĂ©nagement fluvial

    No full text
    Le canal Saint-Georges est un cours d’eau d’origine anthropique construit en 1898 lors de l’installation d’Henri Menier sur l’üle d’Anticosti. Depuis, il a Ă©tĂ© amĂ©nagĂ© pour l’adapter Ă  diffĂ©rents usages. À partir de la fin des annĂ©es 1970, les processus fluviaux ont graduellement façonnĂ© le cours d’eau, entraĂźnant une morphologie plus naturelle. Un projet d’amĂ©nagement du canal Saint-Georges et de ses habitats pour le poisson, rĂ©alisĂ© de 2019 Ă  2022, a aussi menĂ© au dĂ©mantĂšlement d’un barrage, Ă  la stabilisation de berges ainsi qu’à des amĂ©nagements fauniques. Cet article prĂ©sente les trajectoires historiques anthropique et naturelle du canal dans le but de mettre en lumiĂšre leurs interactions. L’évolution des usages du canal Saint-Georges comprend 3 pĂ©riodes distinctes, qui ont chacune influencĂ© les processus fluviaux ainsi que la morphologie rĂ©sultante. Cette Ă©volution Ă  la fois anthropique et naturelle du canal Saint-Georges est caractĂ©ristique de plusieurs cours d’eau amĂ©nagĂ©s, ce qui reprĂ©sente Ă  la fois des possibilitĂ©s et des dĂ©fis de gestion. Ce cas montre l’importance de considĂ©rer la particularitĂ© hybride de ces cours d’eau dans leur restauration et leur amĂ©nagement. À l’avenir, cela pourrait mener Ă  mieux respecter leur fonctionnement potentiel ainsi qu’à mettre davantage en valeur leur patrimoine culturel.The Canal Saint-Georges is an anthropogenic waterway on Anticosti Island (QuĂ©bec, Canada). It was built in 1898, shortly after Henri Menier purchased the island. Since then, it has been adapted for various uses. From the late 1970s onwards, fluvial processes gradually shaped the watercourse, resulting in a more natural morphology. In addition, a fish habitat revitalization project conducted between 2019 and 2022, led to the removal of a dam, stabilization of the banks and creation of wildlife habitat. This article presents the historical anthropogenic and natural trajectories of the canal to highlight their interactions. The evolution of the use of the canal comprises 3 distinct periods, each of which influenced the fluvial processes and the resulting morphology. This combination of anthropogenic and natural evolution is typical of many managed waterways, representing both opportunities and management challenges. The case of the Canal Saint-Georges demonstrates the importance of considering the hybrid nature of such waterways when managing or restoring them. In the future, these considerations could lead to a better respect of their potential functioning as well as to a better enhancement of their cultural heritage
