De la Tierra a la Luna: fotografía astronómica en el siglo XIX

Entre los tesoros bibliográficos que conserva la Biblioteca Histórica de la Universidad Complutense se encuentran las excepcionales obras ilustradas de Camille Flammarion, Les Terres du ciel (1877) y el Atlas celéste (1877), en torno a las cuales reflexionamos aquí sobre la astrofotografía, arte y ciencia en el siglo XIX.

Method for the characterization of Fresnel lens flux transfer performance

Fresnel lenses and other faceted or micro-optic devices are increasingly used in multiple applications like solar light concentrators and illumination devices, just to name some representative. However, it seems to be a certain lack of adequate techniques for the assessment of the performance of final fabricated devices. As applications are more exigent this characterization is a must. We provide a technique to characterize the performance of Fresnel lenses, as light collection devices. The basis for the method is a configuration where a camera images the Fresnel lens aperture. The entrance pupil of the camera is situated at the focal spot or the conjugate of a simulated solar source. In this manner, detailed maps of the performance of different Fresnel lenses are obtained for different acceptance angles.

Tener hambre de luz y devorar una estrella: la poesía de J.E. Eielson

The present Doctoral Thesis is framed within the study of the poetry of the great Peruvian artist Jorge Eduardo Eielson (April 13, 1924 – March 8, 2006). In general terms, it focuses on the symbols that articulate both his literary productions and his work in the field of visual arts. Throughout this project, I used the principles of the modern semiotics as well the myth criticism theory developed by Gilbert Durand in his work The Anthropological Structures of the Imaginary as the basis. Following the assumption of considering Eielsońs work as an indivisible whole, in contrast to many studies that often attempted to analyse part of his creative work by privileging one medium over the others, I analyzed each symbol in all its forms, looked at its presence and relevance in his entire work and sought the archetypal level of each term. For this task, the works of Joseph Campbell and Mircea Eliade provided valuable guidances. At the beginning of this study I present a short author's biography, in order to help to understand the circumstances under which his poems were composed. (Let us remember that most of his books were published many years after their conception). Throughout this chapter, I have carefully considered the Lima period, his relationship with his first mentor, the anthropologist and writer José María Arguedas who introduced him to the knowledge of the ancient civilizations of Peru, his link with the literary circles of Lima and his first acknowledgments: the National Poetry Award (1944) and the National Drama Award (1948)...

Dimensión pedagógica de la obra de Jacques-Martin Hotteterre (1674-1763): estudio analítico e implicaciones educativas para una práctica interpretativa en el estilo, a la luz de su tratado y su producción musical

Este trabajo de investigación se desarrolla en el seno de un conjunto de hechos y determinaciones que –desde la segunda mitad del siglo XX-, emergen con intensidad en los ámbitos europeo y nacional, en torno a la consolidación de la música en todos los niveles de los sistemas de educación y formación. De forma significativa, en los niveles obligatorios, post-obligatorios conforme a los procesos de homogenización, transparencia, y en los superiores en función de la convergencia, la transferencia y la movilidad, desde la propuesta del Espacio Europeo de Educación Superior (EEES). Se inscribe en el marco de la orientación cultural de la enseñanza, del reto del desarrollo competencial y profesional, de la afirmación de los materiales de enseñanza como elementos genéricos de la calidad de la educación. Tiene como objeto de estudio los rasgos, características y cualidades de la cualidad del Tratado de Jacques-Martin Hotteterre (1674-1763), Principes de la flute travesière, ou flute d’allemagne. De la flute a bec, ou flute douce, et du haut.- bois, Divizez par Traitéz (Paris, 1707). Un objeto de estudio configurado en el contexto institucional de los Conservatorios Profesionales y Superiores, en donde se ha incorporado la Música Antigua a la Educación musical y se ha vinculado la enseñanza de la interpretación musical con instrumentos antiguos, como son la flauta de pico y el traverso barroco...
