This paper reexamines orientations of shear bands (fault angles) predicted by a theory of shear localization as a bifurcation from homogeneous deformation. In contrast to the Coulomb prediction, which does not depend on deviatoric stress state, the angle between the band normal and the least (most compressive) principal stress increases as the deviatoric stress state varies from axisymmetric co...

The genus Astyanax is a specious Neotropical fish group, occurring from the south area of the United States to Argentina. During the past few years, intensive studies on representatives of this group have been performed, broadening the genetic, taxonomic and biogeographical knowledge considerably. However, phylogenetic relationships among many species remain uncertain. Significant karyotypic va...

The gene encoding mammary-derived growth inhibitor (MOGI), a protein previously purified from bovine mammary gland and shown to have modest antiproliferative activity for human breast cancer cells in vitro, is demonstrated to function as a potent tumor suppressor gene. Human breast cancer cells transfected with a MDGI expression construct exhibited differentiated morphology, reduced proliferati...

Cytogenetic analyses were accomplished in two populations of Astyanax altiparanae Garutti & Britzki, 2000 and one population of Hyphessobrycon eques Steindachner, 1882, considered incertae sedis in Characidae family. Two populations of Astyanax altiparanae (Mogi-Guaçu and Tietê rivers) presented 2n=50, with the same karyotype formula: 6M+12SM+20ST+12A (FN=88). Hyphessobrycon eques from Capivara...
