Abstract In this essay I discuss the relationship among foreignness, Protestantism and the formal establishment of the Tribunal of the Holy Office of the Inquisition in New Spain in the complex geopolitical context of the 16th century, when the Anglo-Spanish and French-Spanish relationships had been deteriorating. I consider some English and French incursions into New Spain during the 1560s and the early 1570s. These derived into an English contingent and a French one, whose survivors would be the first prosecuted and punished by the Inquisition -which had just been established in Mexico- on the charge of Lutheran heresy.

Resumen En este ensayo considero la relación entre extranjería, protestantismo e Inquisición durante la llegada del Tribunal del Santo Oficio a Nueva España, en un contexto geopolítico en el que las relaciones angloespañolas y francoespañolas se habían deteriorado paulatinamente en el transcurso del siglo XVI. Reviso las incursiones francesas e inglesas al Golfo de México durante la década de 1560 y principios de la de 1570; de éstas, hubo dos contingentes, uno inglés y otro francés, cuyos supervivientes fueron los primeros juzgados y castigados por la Inquisición -ya establecida en México- por cargos de herejía luterana.

In this paper we present the numerical analysis of the quasi-static behavior of an unbalance cracked shaft with straight and elliptical cracks considering an eccentric mass. The rotation of the shaft has been simulated by considering different angular positions to complete one rotation. The influence of the mass eccentricity in the opening of the crack has been studied considering different angles of eccentricity. The study of the partially opening/closing of the crack in the rotation of the shaft under the influence of the eccentric mass is analyzed. The work allows us to know the influence of the unbalance in the crack breathing mechanism and will help to predict the influence of this behavior on the values of the Stress Intensity Factor and on the propagation of cracks.
