We studied in this work the phenomenon of the double diffusive natural, laminar and permanent convection in a rectangular enclosure filled with a binary fluid mixture supposed incompressible with a constant horizontal ...

This work presents a continuation of study of the influence of substitution on the conformation of aromatic molecules. The crystal structure of β -methyl-α dicyanostyréne (C11H8N2) was determined at room temperature by ...

"This work concerns the application of the Feynman path integrals method to two dynamical systems interesting theoretical physics and quantum chemistry. In the context of non-relativistic quantum mechanics, we have undertaken ...

"The work of this Magister’s memory is in the framework of the General Theory of Relativity of Einstein. After a short introduction, followed by a concise but complete presentation of general relativity in order to dispense ...

In this thesis, we have studied two different models of the accelerated expansion of the universe phenomenon. In the first model, we have found that the geometry is responsible for this accelerated expansion of the universe ...
