The slope of the internal annulus is flatter than the 1992, it has expanded into several countries of the former outer indicating the presence of different mass distributions Soviet Union in Eastern Europe and Eurasia. at different radial distances. This is a clear mark of mass As of the year 2003 the Institute is composed of fifteen segregations, as expected in dinamically relaxed systems as Branches in nine countries. ͑see figure on following page͒.
