The Cuban Convention and its Role in the Cuban Revolutionary Party
In June 1892, Luis Lagomasino, an agent of a secret organization known only to its members as the Cuban Convention was summoned to Key West to provide an update on the preparations underway in Cuba for the revolution. Lagomasino, the Convention\u27s agent in the eastern province of Las Villas, arrived in Key West on June 22, 1892, where he was affectionately received by Jose Dolores (J. D.) Poyo and General Serafin Sanchez, who introduced him to the wealthy industrialist, Eduardo H. Gato, and the veteran insurgent leader, Fernando Figueredo Soccards. On the night of June 24, 1892, Lagomasino met with the Convention\u27s members at the home of Fernando Figueredo. Of the 25 members, only two were absent from Key West at that time: Jose Marti, Delegate of the newly formed Cuban Revolutionary Party and Teodoro Perez, a wealthy cigar manufacturer. After Lagomasino convinced the members present that there was sufficient support in the eastern provinces of Cuba to initiate the revolution two months later on August 25, 1892, members of the Convention declared war on Spain and promised Lagomasino that they would send sufficient arms and munitions to equip the soldiers of the Cuban liberating army.
Simultaneous aluminum, silicon, and sodium coordination changes in 6 GPa sodium aluminosilicate glasses
We present the first direct observation of high-coordinated Si and Al occurring together in a series of high-pressure sodium aluminosilicate glasses, quenched from melts at 6 GPa. Using ^(29)Si MAS NMR, we observe that a small amount of Al does not have a significant effect on the amount of ^VSi or ^(VI)Si generated, but that larger Al concentrations lead to a gradual decrease in both these species. ^(27)Al MAS NMR spectra show that samples with small amounts of Al have extremely high mean Al coordination values of up to 5.49, but that larger Al concentrations cause a gradual decrease in both ^VAl and ^(VI)Al. Although mean Al and Si coordination numbers both decrease with increasing Al contents, the weighted combined (Al+Si) coordination number increases. Silicon and Al resonances shift in frequency with increasing pressure or changing Al concentration, indicating additional structural changes, including compression of network bond angles. Increases in the ^(23)Na isotropic chemical shifts indicate decreases in the mean Na-O bond lengths with increasing pressure, which are more dramatic at higher Al contents. Recovered glass densities are about 10 to 15% greater than those of similar ambient pressure samples. However, the density increases due to the combined coordination changes of Al and Si are estimated to total only about 1 to 2%, and are roughly constant with composition despite the large effects of Al content on the individual coordinations of the two cations. Thus, effects of other structural changes must be significant to the overall densification. Apparent equilibrium constants for reactions involving the generation of high-coordinated species show systematic behavior, which suggests an internal consistency to the observed Si and Al coordination number shifts

Cosmic Microwave Background Radiation Anisotropy Induced by Cosmic Strings
We report on a current investigation of the anisotropy pattern induced by
cosmic strings on the cosmic microwave background radiation (MBR). We have
numerically evolved a network of cosmic strings from a redshift of to
the present and calculated the anisotropies which they induce. Based on a
limited number of realizations, we have compared the results of our simulations
with the observations of the COBE-DMR experiment. We have obtained a
preliminary estimate of the string mass-per-unit-length in the cosmic
string scenario.Comment: 8 pages of TeX - [Color] Postscript available by anonymous ftp at
