Environmental weathering of natural and artificial stones used in historical architecture: influence of microstructure and new restoration methods

For some study cases (the Cathedral of Modena, Italy, XII-XIV century; the Ducal Palace in Mantua, Italy, XVI century; the church of San Francesco in Fano, Italy, XIV-XIX century), considered as representative of the use of natural and artificial stones in historical architecture, the complex interaction between environ-mental aggressiveness, materials’ microstructural characteristics and degradation was investigated. From the results of such analyses, it was found that materials microstructure plays a fundamental role in the actual extent to which weathering mechanisms affect natural and artificial stones. Consequently, the need of taking into account the important role of material microstructure, when evaluating the environmental aggressiveness to natural and artificial stones, was highlighted. Therefore, a possible quantification of the role of microstructure on the resistance to environmental attack was investigated. By exposing stone samples, with significantly different microstructural features, to slightly acidic aqueous solutions, simulating clean and acid rain, a good correlation between weight losses and the product of carbonate content and specific surface area (defined as the “vulnerable specific surface area”) was found. Alongside the evaluation of stone vulnerability, the development of a new consolidant for weathered carbonate stones was undertaken. The use of hydroxya-patite, formed by reacting the calcite of the stone with an aqueous solution of di-ammonium hydrogen phosphate, was found to be a promising consolidating tech-nique for carbonates stones. Indeed, significant increases in the mechanical prop-erties can be achieved after the treatment, which has the advantage of simply con-sisting in a non-hazardous aqueous solution, able to penetrate deeply into the stone (> 2 cm) and bring significant strengthening after just 2 days of reaction. Furthermore, the stone sorptivity is not eliminated after treatment, so that water and water vapor exchanges between the stone and the environment are not com-pletely blocked.

Celestial Church of Christ in Italia. Percorsi, Spazi e Pratiche Rituali

Il lavoro che presento propone un’analisi di una chiesa africana indipendente in Italia, la Celestial Church Of Christ Worldwide (CCCW), cercando di mettere in luce il nesso tra religione, migrazione e il processo di ‘plunting churches’ (Kooning 2009) nel contesto italiano. Attraverso una ricerca sul campo, sono stati indagati i percorsi personali, familiari e comunitari dei membri di una ‘Celestial Parish’ presente nel comune di Brescia, ‘Ileri Oluwa Parish’, al fine di comprendere la natura dei processi identitari coinvolti nell’organizzazione della CCC in Italia. ‘Ileri Oluwa Parish’, in quanto luogo che denota una ‘chiesa individuale collegata ad una Diocesi’ (CCC Constitution (CCC Constitution, 107 (d) si rivela, nella materialità delle sue forme e dei ‘Devotional Services’ che in essa si svolgono, a ‘field of action’ (Lefebvre, 1991). La storia della chiesa, i fondamenti della sua dottrina e i significati comunicati attraverso le forme rituali e religiose che la stessa promuove, sono stati contestualizzati alla luce delle tensioni e delle strategie di potere che strutturano il campo. Le storie dei membri della parrocchia, percorsi di migrazione e mobilità in itinere, rappresentano la lente attraverso cui si è guardato alle relazioni vissute nel nome dello ‘Spirito’, e alla percezione stessa di ciò che gli stessi Celestians definiscono sacro, santo, puro e impuro. Lo sguardo fisso alla vita ordinaria di una Celestial parish in Italia, esteso nell’ultima parte dell’elaborato alla Celestial parish londinese, è stato fondamentale per capire l’intreccio di relazioni spirituali, reti familiari e mobilità degli individui sul territorio italiano ed europeo, processo che ribalta la condizione diasporica della CCC, trasformando una condizione di dispersione in un valore aggiunto, nella possibilità di nuove traiettorie territoriali e spazi di presenza religiosa e socioeconomica.

La censura del tema deportivo en la prensa durante la posguerra española (1939-1945)

La presente tesis doctoral pretende arrojar nueva luz sobre la utilización de la prensa durante los primeros años del franquismo. En concreto, el objetivo ha sido estudiar la censura del tema deportivo dentro del sistema censorio de los primeros años de posguerra civil en España, una área no estudiada hasta hoy y que entendemos fundamental para entender el desarrollo del deporte durante el llamado primer franquismo. Para ello, se estudiaron de manera pormenorizada los actores principales y los pasos básicos del proceso de censura; los métodos utilizados, tanto materiales como personales, para hacer efectiva ésta; y, por último, sus manifestaciones reales en el ámbito de la información deportiva: qué se censuró, por parte de quién, de qué forma y por qué motivos. De este modo, pretendemos llenar una de las lagunas de investigación que aún quedan dentro del estudio de la censura de prensa durante el franquismo. La metodología utilizada es la técnica historiográfica. Basado en el análisis crítico y en la interpretación de fuentes primarias, dicho método trata de establecer marcos históricos de referencia a través del estudio pormenorizado de las circunstancias del pasado. Ello implica una estructura algo distinta a la de las tesis doctorales de otras áreas de estudio puesto que, exceptuando la introducción, toda la tesis es la exposición de los resultados de la investigación llevada a cabo. Se ha utilizado cuantiosa documentación de los archivos General de la Administracion (Alcalá de Henares) y Centrale dello Stato (Roma) no manejada anteriormente por ningún investigador. La prensa periódica de la época y la legislación que afecta a nuestro tema de estudio también han sido ampliamente investigadas, tanto en el contexto español como en el italiano. Nuestra investigación arroja los siguientes resultados. Efectivamente, existió censura de prensa en el tema deportivo en las siguientes temáticas fundamentales: cuestiones económicas, autoridades y jerarquías, uso del lenguaje y comportamiento de los deportistas. En la mayor parte de los casos, la censura se ejerce en la información deportiva por razones ajenas al propio deporte. No se puede afirmar que existan diferencias en el tratamiento general entre medios de la Prensa del Movimiento y otros de titularidad privada o eclesiástica, si bien la aplicación de la censura no fue homogénea sino arbitraria en muchos casos. El sistema de censura de prensa español del primer franquismo toma la mayoría de sus rasgos del modelo fascista italiano, aunque tiene alguna característica propia como la censura previa y el catolicismo imperante. ABSTRACT This doctoral thesis aims to shed light on the use of press during the first years of francoism. The particular objective was to study the censorship of the sport topic into the general system of censorship carried out after the Spanish Civil War. It is a subject comparatively understudied to date but a key aspect to understand the development of sport during the so called early francoism. To this end, an in-depth study was made on key actors, main steps of censorship process, human and material methods used to ensure its effectiveness, and the actual manifestations in sports information area: what was censored, by whom, how and why. This should ensure us to fill the historiographical gap within the research on Francoʼs press censorship. Methodology used was historiographic research. It is based on critical analysis and interpretation of primary sources and seeks to establish historical reference frameworks tracing back the past in detail. It determines a different doctoral thesis structure in some aspects. Except the introduction, the whole document is the report and explanation of the results of research. A large amount of unexplored documents from the Archivo General de la Administración (Alcalá de Henares, Spain) and the Archivio Centrale dello Stato (Rome, Italy) has been used. The press of the period and legislation about our topic have also been analysed in detail both in Spain and Italy. Our research states these results. We can affirm that press censorship actually existed on sports topic in these thematic priorities: economical issues, authorities and hierarchies, use of language and sportsmen behaviours. In most cases, the censorship of sports information is exercised for reasons unconnected to sport. It cannot be concluded that general differences were applied in press censorship between State-owned media and private or church media although its implementation was non-uniform and arbitrary in many cases. The system of press censorship in Spain during the early francoism is clearly inspired by fascist Italy system copying most of its features although Spain had a few specific characteristics like prior censorship and catholicism.

Alzamiento de la Iglesia-Cementerio de San Pedro y San Pablo en la Isla de Nueva Tabarca

El objeto de la presente comunicación es mostrar los trabajos del levantamiento de la Iglesia de San Pedro y San Pablo en la Isla de Nueva Tabarca, iniciados en 1998 y todavía no concluidos. Sin duda, una labor de relevante importancia debido al estado aparente de avanzado deterioro del inmueble. Para redactar el proyecto de restauración fue necesario un levantamiento preciso y minucioso ya que prácticamente no se disponía de ninguna documentación gráfica, los documentos gráficos localizados sólo ofrecían pistas, pero no daban una base documental suficiente como para acometer los trabajos de restauración. En la presente comunicación se describen: el proceso de toma de datos, levantamiento de la iglesia y la casa parroquial; los descubrimientos aportados por el levantamiento gráfico; así como las aportaciones realizadas al proyecto y a la construcción gracias al mismo.
