Reflections on the role of chemical osmosis mechanisms on the long-term behavior of a collapsed salt cavity by Ledoux, Emmanuel, Hertz, Emmanuel, Robinet, Jean-Charles, Combes, Pierre

“…Recent work on chemical osmosis in clay media, motivated by research on the geological storage of nuclear waste in a clay layer, raises questions about the role of this mechanism on the long-term behavior of the system.Based on a bibliographical approach, the article presents a brisk synthesis of the theory of chemical osmosis and discusses its application to the case of clayey rocks which can constitute imperfect membranes capable of generating osmotic pressures.First, the article presents the equations representing the flow of the fluid and the solute transport according to a simplified formulation adapted to the geometry of the system. …”

Development of a new method for measuring the electric field strength based on a dual electro-induction sensor by S. V. Biryukov, A. V. Tyukin, L. V. Tyukina

“…The method of measurement by the mean value assumes simultaneous measurement of two values of intensity E1 and E2 in one point of electric field with opposite sign errors. As the theory of construction of the new method has shown, it is possible to determine not only the measurement result as an average of two values of the strengths, but also to estimate the error of the measurement result and tentatively determine the distance to the field source. …”
