The Ising spin S model on recursive p polygonal structures in the external magnetic field is considered and the general form of the free energy and magnetization for arbitrary spin is derived. The exact relation between the free energies on infinite entire tree and on its infinite ”interior” is obtained. e-mail: [email protected] e-mail: [email protected] Permanent address: Ye...

The most significant example of the difficulties caused by the given borders is the conflict with neighbouring Azerbaijan over the territory of Nagorny Karabakh. As a consequence of the Nagorny Karabakh ...

BACKGROUND Article 20 of the World Health Organisation Framework Convention on Tobacco Control calls for a cross-country surveillance of tobacco use through population-based surveys.
