Design and analysis of reinforced rubber membranes for inflatable dams

The aim of the present paper is to present actual calculation approaches and design aspects of inflatable dams. The analytical calculation of design relevant stresses in the membrane of inflatable dams is too vague. Therefore, finite element analyses are needed to get the stresses of the multi-ply composite material with cover layers of rubber. Because of the rubber layers the inflatable dams are sometimes called rubber dams. In the end of the actual investigations, there should be a design concept for inflatable dams accordant to the Eurocode-concept. Stress concentration factors, gained of finite element calculations, lead to the relevant stresses. Reduction factors for the different material behaviours are determined independent of numerous calculations

Community Oral History to widen the path: The Jewish Mobile Oral History Project

This article presents the case study of the Jewish Mobile Oral History Project of the McCall Library at the University of South Alabama as an example of a participatory archival practice. With goals to build a collection centered on a minority experience, to engage with community members, and to foster inter-communal dialogue, the project highlights affect as one vital consideration for archival record keepers, users, and subjects

The local population and museums. An analysis based on the use of museums in the Alt Pirineu and Aran Region (Catalonia, Spain)

This paper is based on a study of visitors to the museums in the Alt Pirineu and Aran region (Catalonia, Spain). We describe the characteristics of the museums’ users and analyse the relationship between the museums and the local community. We highlight the importance of these facilities for local development, and the need to consider and prioritize their role as culture centres for the region’s population. Keywords: Visitor studies, local community, local museum, High Pyrenees, Aran Valley

Àger, un topònim berber a la Marca Superior d'Al-Andalus

The medieval arabic chronicles document a fortification in the septentrional frontier of Al-Andalus called Agira, now Àger, in the region of la Noguera. The archaeological data point out that it is a mjlitary settlement probably of the IX century. Moreover, the existence of a place-name similar to Magreb makes you think of the establishment in this area of a berber tribal fraction called Banû Agàr during the period of the islamic domination of the Iberian peninsula
