We study the stability properties of constant mean curvature (CMC) surfaces of revolution in general simply-connected spherically symmetric 3-spaces, and in the particular case of a positive-definite 3dimensional slice of Schwarzschild space. We derive their Jacobi operators, and then prove that closed CMC tori of revolution in such spaces are unstable, and finally numerically compute the Morse...

Iran's Islamic revolution had so many effects on political, social, cultural and economic conditions of Shiites outside of Iran and caused a special formation of Muslims identity beliefs in the world, especially shia Muslims. Islamic revolution was a turning point in the Saudi Shia movement to get their spoiled rights by governance structure in Saudi Arabia and helped Shia movements to revive a...

The Triassic has long been recognized as a time during which marine and terrestrial ecosystems modernized dramatically, it seems to have two-step process. First, recovery from the Permian-Triassic mass extinction (PTME) was of extraordinary renewal novelty, these processes change were enhanced, seems, by effects Carnian Pluvial Episode (CPE). After CPE, in oceans, not only did carbonate factory...
