The calculations in Thomas-Fermi approximation show that in a gravitational field each cell of ultra dense matter inside celestial bodies obtains a very small positive electric charge. A celestial body is electrically neutral as a whole, because the negative electric charge exists at its surface. The positive volume charge is very small, on the order of magnitude it equals to 10 −18 e per atom ...

The Monteggia fracture is one of the pitfalls of conventional diagnosis of upper limb trauma. Through a retrospective study of 20 cases diagnosed at the Department of Orthopaedic Surgery and Traumatology, University Hospital Center, Ibn Sina, Mohamed V University, Rabat, Morocco, between 2010 and 2014, we have tried to do an update on the management of Monteggia fractures either at of paraclini...

We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their center of mass or strictly static configurations.

Abstract This article provides the first discussion of unpublished treatise De crepusculis (“On twilight”), written in second half thirteenth century by Dominican scholar Giles Lessines. It is shown that was intended as a critical supplement to on height atmosphere Ibn Muʿādh (eleventh century). In this supplement, recapitulates Muʿādh’s geometrical arguments while furnishing proofs and coverin...

Vitiligo is a skin disease that has been known about for at least 5000 years, but little has been done to understand its causes or to evaluate possible treatment. It is not a painful condition and perhaps that is why it is often trivialized and left untreated. Vitiligo is characterized by depigmented areas of skin. There are several different theories One theory is that people develop antibodie...
