In this article, a collaborative writing group explores how we, two rivers, express ourselves over time, place and space, our energies long interpreted as veins and arteries carrying the Country's life affirming blood. Voiced as River: I, River, this position reflects a worldview in which interrelationship with living river is normal, and River Spirit is ever‐present. It is a position underpinned by Indigenous narratives as riverine expressions of place‐based love. At times, the article is also voiced as a writing group or individuals, with voices being interchanged where required for smooth reading. We see this as part of the decolonising process, which feels liberating and healing among the writers. Each writer is equally valued as co‐creator, contributor, narrator and story teller. The two rivers, being Martuwarra Fitzroy River (Kimberley, Western Australia) and Unamen Shipu Romaine River (North Shore, Québec, Canada), illustrate a common condition of being, through heritage, life, change and possibility. Through stories and voices, the socio‐scientific implications of colonisation and lost connections become clear, considering the interaction, the dialogue and the cultural synthesis of living water systems that have always incorporated all life forms into rivers of life. As a way of navigating towards wholeness, Aboriginal knowledge systems and narratives for healing are used to bring together findings of this intercultural river learning journey.

Les milieux ruraux sont actuellement confrontés à de nombreux changements occasionnés, entre autres, par l’arrivée et l’insertion de nouvelles populations désirant s’y établir en permanence. Ce phénomène touche plusieurs pays, ce qui pose de nouveaux défis, aussi bien pour les décideurs locaux que pour l’ensemble de la communauté rurale. Cet article permet de mieux connaître cette situation peu étudiée au Québec, en apportant un éclairage nouveau sur les trajectoires résidentielles, les motifs de migration ainsi que l’insertion professionnelle et sociale des nouvelles populations rurales. En relevant les convergences et les divergences caractérisant les néo-ruraux de deux MRC contrastées (Brome-Missisquoi et Arthabaska), son objectif est de faire ressortir l’hétérogénéité et la complexité de ces populations.Rural communities currently face many changes caused, among other things, by the arrival and integration of new populations wishing to settle there permanently. This phenomenon affects a number of countries, raising new challenges both for local decision-makers and for the rural community as a whole. This paper provides a better understanding of this situation, which has not been widely studied in Québec, by shedding new light on residential trajectories, on reasons for migration and on the occupational and social integration of new rural populations. By noting aspects of convergence and divergence among neo-rural populations in two contrasting RCMs (Brome-Missisquoi and Arthabaska), its aim is to bring out the complex heterogeneous nature of these populations

The authors present a computer vision technique for the acquisition and processing of 3-D images of the profile of wax dental imprints in the automation of diagnosis in orthodontics. The acquisition of the 3-D images is based on the absorption of light by a dispersive medium and uses standard CCD (charge coupled device) cameras. The profiles of both sides of the imprint are acquired simultaneously. The 3-D image of each side of the imprint is segmented by nonlinear filtering of the 3-D data, and the interstices between the teeth are detected. Two operators are presented: one for the detection of the interstices between the teeth for incisors, canines, and premolars, and one for those between molars. A method for deciding the optimal neighborhood of application of each operator is also presented. Experimental results show that the two operators are very effective at detecting the interstices.
