Este artigo parte do objetivo de investigar o fazer poético Autran Dourado, no seu romance Ópera dos mortos, 1967. A intrigante relação estabelecida entre os membros sobrado, criados a partir universo ficcionista autraniano, resulta comportamento ambivalente da protagonista, Rosalina. Esta, tem final trágico já prenunciado, assim como todo clã Honório Cota, demonstrando que é impossível ludibri...

Cota-Robles, Eugene H. (University of California, Riverside). Electron microscopy of plasmolysis in Escherichia coli. J. Bacteriol. 85:499-503. 1963.-Escherichia coli cells plasmolyzed in 0.35 m sucrose reveal plasmolysis at one tip of a cell or in the center of dividing cells in which protoplast partition has been complete. Central plasmolysis reveals that protoplast separation can be complete...

On July 18, 2012, Jordán Pascual Espada defended his PhD thesis at Oviedo University, titled: “Design service-oriented collaborative virtual objects within Internet of things”. The research was funded by the Government of the Principality of Asturias (Spain). Jordán Pascual Espada defended his dissertation in a publicly open presentation held in the School of Computer Engineering at Oviedo Univ...

In a previous article it was proved that the extensions of the TaubNUT geometry do not admit Killing-Yano tensors, even if they possess Stäckel-Killing tensors. Here the analysis is taken further, and it is shown that, in general, this class of metrics does not even admit fsymbols. The only exception is the original Taub-NUT metric which possesses four Killing-Yano tensors of valence two. 1 Ext...

We investigate the SO(4, 1) gauge-invariant theory of the Dirac fermions in the external field of the Kaluza-Klein monopole, pointing out that the quantum modes can be recovered from a Klein-Gordon equation analogous to the Schrödinger equation in the Taub-NUT background. Moreover, we show that there is a large collection of observables that can be directly derived from those of the scalar theo...
