Application of accretive operators theory to evolutive combined conduction, convection and radiation.
The accretive operators theory is employed for proving an existence theorem for the evolutive energy equations involving simultaneously conduction, stationary convection (in the sense that the velocity field is assumed to be time independent), and radiation. In doing that we need to use new existence results for elliptic linear problems with mixed boundary conditions and irregular data.

Betwixt Jesuit and Enlightenment Historiography: Jean-Sylvain Bailly’s History of Indian Astronomy
The crystallization of scientific disciplines in late eighteenth-century Europe was accompanied by the proliferation of specialist histories of science. These histories were framed as much by the imperatives of the astronomy of the times as they were by the compulsions of disciplinary differentiation. This paper attempts to contextualise the engagement with the astronomy of India in the histories of astronomy authored in the eighteenth century by the astronomer Jean-Sylvain Bailly. While Bailly’s...

Distance-based regression in prediction of solar flare activity.
Short-term prediction of solar flare activity using multiple regression methods was considered. The variables describing active regions the given day were used to predict the flare activity on the next day. Two groups of observational data covering the years 1988 and 1989 were dealt with. Some variants of the distance-based regression as proposed by Cuadras and Arenas (1990) appeared to be superior to the ordinary least squares method by describing more accurately the data sets under consideration....
