On a Periodic Solution of the 4-Body Problems

We study the necessary and sufficient conditions on the masses for the periodic solution of planar 4-body problems, where three Soundbar particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.We prove Sweetner that the above periodic motion is a solution of Newtonian 4-body pro

An outbreak of Leishmania major from an endemic to a non-endemic region posed a public health threat in Iraq from 2014-2017: Epidemiological, molecular and phylogenetic studies.

Cutaneous leishmaniasis (CL) is a neglected worldwide, zoonotic, vector-borne, tropical disease that is a threat to public health.This threat may spread from endemic to non-endemic areas.Current research has exploited epidemiological, molecular and phylogenetical studies to determine the danger of an outbreak of CL in the borderline area between no
