“…[1][2][3][4] A pronounced effect of an electric field on the kinetics of phase separation has been seen by other studies, 5,6 which note a marked acceleration of separation in a complex silicate glass for low-frequency fields of modest intensities. For this reason, the influence of phase separation on crystallization has been extensively studied, with particular attention directed to its effect on crystal nucleation.…”

In the present paper, the process of phase separation in calcium aluminosilicate glasses (CAS glasses) containing TiO 2 as a nucleating agent is studied. A static electric field promotes the process of phase separation even when the time of heat treatment is short. The effect of electric field on phase separation acts through the higher polarizability of Ti ions. Alkali ions, when present, will diffuse toward the cathode, which may generate different micromorphology at the parts of samples near the cathode and the anode. X-ray photoelectron spectroscopy and Raman spectra analysis confirm the conclusion that the electric field has promoted phase separation in CAS glasses.

Since 1959, Castro's Cuba has remained a politically repressive, economically stagnant, militarily adventuristic state. The legitimacy of the Cuban regime depends, in many ways, on the persona of Fidel Castro; when he dies, the government will face by far its severest test to date and, most probably, at a time when a potentially deadly economic and systemic crisis continues to threaten the Cuban polity. Revolutionary or reformist elements will almost certainly emerge to demand change.What would happen next is the subject of this essay. It will address a two-part question: what are the chances for a revolution in post-Castro Cuba? and if one occurred: what form would it take?The fate of the Cuban regime post-Castro is a crucial question for the next US administration and its successors. The degree to which US foreign policy is affected by Cuban behavior suggests that, apart from regime change in the Soviet Union, a change of government in Cuba carries more implications for US policy than any change of government in the world. Now is an opportune time to examine the potential for such change. Michael J.
