Effect of surface mobility on the uniformity of a thin film under a bubble.

The shape of a soap bubble placed on a solid surface is familiar to everyone-a thin hemispherical dome that thickens near the solid surface. This structure is stabilized by the balance between the film's elasticity, provided by surfactant molecules, and the pressure inside the bubble. However, there is also a soap film on the flat solid surface that has been mostly ignored in previous studies; its thickness is typically assumed to be constant or varying monotonically.

[Nursing practice in the context of geographic isolation: implications for training].

A survey on the characteristics of the unique working context of nursing practice in remote areas of French Polynesia and semi-remote areas of northern Quebec demonstrates the importance of a specific training to best prepare the professionals who find themselves in this type of setting. Twenty professionals were interviewed: six nurses practicing in isolated stations in French Polynesia (Tuamotu Archipelago, Marquesas Islands and Austral Islands), six nurses practicing in semi-remote areas within northern Quebec (namely among the Algonquins, the Crees and the Attikameks), four officials of the French Polynesian Health Directorate and four training programme designers from Quebec who were encountered during an expedition to Montreal, Mistissini and Trois-Rivieres. The authors identified ten characteristics which were then regrouped into two categories for both of the practice contexts: first, those inherently linked to professional practice in an isolated context (including the characteristics of nursing practice, the working conditions, the community's health problems, their forms of socio-professional relations, their way of life, and their perception and responses to isolation); and second, those pertaining to the social and natural environment, the economic conditions and the community's cultural specificities.
