[ES] El proyecto tiene como objetivo estudiar el proceso de fabricación de las ruedas que afectan a la distribución de tensiones residuales en las ruedas junto con los diferentes métodos de medición para establecer los criterios de aceptación en producción. Para ello, se realizará un análisis de antecedentes y revisión de la normativa aplicable, se definirá un plan de pruebas para el estudio de los parámetros que influyen en el proceso (integrándose en un equipo de trabajo multidisciplinar) y de los métodos de inspección, se realizará un seguimiento del plan de pruebas y se analizará resultados derivados del plan de pruebas.

While most critics have noted the profound affinity Remedios Varo felt with the ideas she encountered in the esoteric philosophy of G. I. Gurdjieff and his pupil P. D. Ouspensky, only in recent years have they begun to uncover the extent to which this teaching informed her richly symbolic work. This article shows how Gurdjieff’s views on ‘personality’ and ‘essence’, as outlined in Ouspensky’s exposition of his master’s ideas, In Search of the Miraculous, informed Varo’s depiction of a quest for spiritual equilibrium. In doing so, it brings to light the importance Varo placed in the development of a robust, spiritual Self.

We present optical observations of the peculiar stripped-envelope supernovae (SNe) LSQ12btw and LSQ13ccw discovered by the La Silla-QUEST survey. LSQ12btw reaches an absolute peak magnitude of M-g = -19.3 +/- 0.2, and shows an asymmetric light curve. Stringent pre-discovery limits constrain its rise time to maximum light to less than 4 d, with a slower post-peak luminosity decline, similar to that experienced by the prototypical SN Ibn 2006jc. LSQ13ccw is somewhat different: while it also exhibits a very fast rise to maximum, it reaches a fainter absolute peak magnitude (M-g =-18.4 +/- 0.2), and experiences an extremely rapid post-peak decline similar to that observed in the peculiar SN Ib 2002bj. A stringent pre-discovery limit and an early marginal detection of LSQ13ccw allow us to determine the explosion time with an uncertainty of +/- 1 d. The spectra of LSQ12btw show the typical narrow He I emission lines characterizing Type Ibn SNe, suggesting that the SN ejecta are interacting with He-rich circumstellar material. The He I lines in the spectra of LSQ13ccw exhibit weak narrow emissions superposed on broad components. An unresolved H alpha line is also detected, suggesting a tentative Type Ibn/IIn classification. As for other SNe Ibn, we argue that LSQ12btw and LSQ13ccw likely result from the explosions of Wolf-Rayet stars that experienced instability phases prior to core collapse. We inspect the host galaxies of SNe Ibn, and we show that all of them but one are hosted in spiral galaxies, likely in environments spanning a wide metallicity range.
