[ES]El colegio de los jesuitas de Orduña, uno de los más tardíos de todo el País Vasco, sigue en su fundación un patrón característico en los casos de mecenazgo indiano: benefactor oriundo, capital consolidado sobre el comercio y el servicio de la Corona, y diseño dirigido desde el otro lado del Atlántico, en este caso desde el Perú. El presente artículo aporta algunas claves sobre esas cuestiones, y ahonda en la formación del patrimonio que la Compañía de Jesús logró reunir en esta ciudad aduanera del Señorío de Vizcaya hasta el momento de la expulsión decretada por el rey Carlos III.

[ES]Cuando a partir de 1564 las salinas de Añana comenzaron a producir para la Corona, sus propietarios se vieron obligados a pagar al rey un tributo anual por el uso de las mueras, admitidas como un ius regalia de la monarquía: el diezmoseñor. Desde entonces, todo el entramado de la fabricación y venta de la sal se organizó en torno a él. En este artículo se analizan algunas de las características de este canon tan singular que se mantuvo en vigor hasta el siglo XX.

[ES] En la iglesia de San Miguel Arcángel, en Irura, encontramos uno de los retablos más interesantes de finales del Renacimiento en Gipuzkoa. El altar posee relieves y tallas de estilo romanista de gran calidad, junto con una mazonería manierista. La obra fue realizada en las postrimerías del siglo XVI por los artistas Pedro de Goicoechea y Jerónimo de Larrea, miembros del taller de Tolosa, siguiendo las trazas dadas por escultor Juan de Goicoechea.

This paper presents a theoretical and experimental study of multidirectional steel fibers reinforced concrete slabs (SFRC). The study is based on a real building application using SFRC flag slabs. For the evaluation of the slabs bearing capacity, plastic calculations are performed both at section and structure levels. The section analysis uses the perfect plastic stress-strain diagram, with reference to the values of the strength characteristics of SFRC based on previous jobs that used similar fibers and dosages. In the structure analysis the plastic yield lines method has been used. This method relates the section last bearing moment and the plastic collapse load. The experimental campaign has consisted of the testing of six 2 m. diameter circular shaped slabs prototypes, and has allowed to verify the reference resistance used in the calculations.

La adaptación de los medios de comunicación tradicionales a los nuevos soportes digitales y su interfaz, lejos de constituir un mero ajuste técnico, ha contribuido a una paulatina transformación de los propios medios y sus audiencias. En una muestra integrada por los diarios de información general y de pago líderes en los 28 países de la UE, y mediante el análisis de 17 indicadores distribuidos en cuatro categorías, este artículo busca identificar las transformaciones que la implantación de los soportes digitales han provocado en las principales cabeceras de la prensa europea. En términos generales, los resultados de la investigación señalan que la mayoría de los diarios no sólo han logrado mantener su liderazgo en la Red, sino que en algunos casos también se está alumbrando un incipiente conjunto de medios globales a partir de medios nacionales preexistentes. Los soportes digitales y móviles también han favorecido la aparición de nuevos hábitos de consumo, caracterizados por una lectura más esporádica y superficial por parte de los usuarios, y han configurado una audiencia que ya en muchos casos es multisoporte, y donde los dispositivos digitales aportan ya la mayoría de lectores a muchos medios. Asimismo, las nuevas ventanas de acceso a la información –buscadores, redes sociales, etc.– generadas por Internet, también están contribuyendo decisivamente al cambio de las rutinas y las formas de trabajo de los propios medios.

The adaptation of traditional newspapers to new digital media and its interface, far from being a mere technical transformation, has contributed to a gradual change in the media themselves and their audiences. With a sample including the top general information pay newspaper in each of the 28 countries of the European Union, this research has carried out an analysis using 17 indicators divided in 4 categories. The aim is to identify the transformations that the implementation of digital media have brought to the top European newspapers. In general terms, the results show that most dailies have managed to keep their leadership also in online environment. Moreover, an emerging group of global media is growing up, based in preexisting national media. Digital and mobile media have contributed to the appearance of new consumption habits as well, where users read more superficially and sporadically. The audience uses several formats at a time, and digital devices already bring the biggest amount of users to many media. The Internet-created new information windows –search engines, social networks, etc. –are also contributing to the change in professional work routines.

Reinforced concrete structures are introduced in Spain mainly by French influence. This happens in the late nineteenth century, following the scheme operating through proprietary systems prevailing in Europe. Systems initially have poor scientific support reaching, even early twentieth century, an impediment to the development of concrete structures, due to the lack of knowledge shown, as well as due to a series of accidents. Therefore, from the end of the first decade of the past century are enacted a series of regulations in many countries, that will change the design and calculation of reinforced concrete structure. The knowledge of the environment of the patent systems, its beginnings and the circumstances of their application allow us to understand the constraints of the early concrete structures, as presented in the Bilbao wine store (1906).

By means of this analysis, we have endeavored to evaluate and understand both the influence that the IETcc started to bear on scientific progress in Bilbao, mainly during the 1960s and the 1970s, as well as the determined efforts of the local financial and industrial elite of the time to transform Bilbao into the great metropolis of the north, i.e. the economic capital of that part of Spain, using as a model, among other metropolises, New York, the financial capital of America, and Pittsburg, the industrial capital. The various means to accomplish this have been studied: from the institutions of investigation, exposition and information which would initiate the longed for scientific progress, to the pathways for reproducing the fascinating American way.

The article analyses the construction process, the evolution and the disturbing future of the facade enclosure of the collective housing constructions built during the developmental period in the province of Gipuzkoa. 128 residential complexes were checked, and 17 people who directly took part in the construction of many of these buildings were interviewed. After examining the material and elements that make up the conventional facade solution used in Gipuzkoa and in much of Spain not only during those years but also up to the present time, the effects and causes of its main damages and flaws were studied. Its complex and costly adaptation to current demands is going to require a strong effort from society at large, and this raises the question of whether the life cycle of this construction system should be terminated once and for all.

The interest of HACFRA (self compacting concrete reinforced with steel fibers), is the combination of the residual strength increase and cracking decrease compared to plain concrete by the introduction of steel fibers in the mass with the advantages of the self-compacting. The paper presents an analysis of the influence of different components of the HACRFA and provides their selection, refered to the granular skeleton and to different steel fiber types and amount, in order to obtain an optimization of its features and structural behavior.
