Resumo Entende-se que o conceito de cidade-dormitório, há muito presente nas discussões sobre São Gonçalo-RJ, provoca uma ausência: as várias possibilidades de ver e representar a cidade se ofuscam sob a onipresença desse conceito. Procuramos tratar das implicações da cristalização de certas representações que se conformam em torno dele. Entende-se que, quando deixa de ser mediação entre o vivido e o concebido, o conceito pode se cristalizar e bloquear o entendimento. Neste artigo, recuperamos alguns usos do conceito cidade-dormitório na Região Metropolitana do Rio de Janeiro confrontando-os com dados da realidade atual do município. Também discutimos implicações simbólicas e materiais devidas à cristalização dessas representações, acompanhadas de seu papel na produção do espaço da cidade. Como resultado de pesquisa, concluímos que é preciso fazer emergir um entendimento que ultrapasse a primazia do centro metropolitano; há que compreender as representações para deslindar seus nós, observá-las para ver além delas. Abstract The concept of commuter town, always present in discussions about São Gonçalo-RJ, provokes (when it becomes evident) an absence: the multiple possibilities of representing the city are obfuscated by the omnipresence of the concept. We seek to deal with the implications of the crystallization of representations that are formed around the commuter town concept. When the concept ceases to be a mediation between the experienced and the conceived, it can crystallize and cause a blockage of understanding. Along this paper, we recall some uses of the commuter town concept in Rio metropolitan region, confronting them with some data regarding the municipality’s current situation. Subsequently, we deal with symbolic and material implications derived from the crystallization of these representations and their role in the production of urban space. As a result, we concluded that it is necessary to develop an understanding that goes beyond the dominance of the metropolitan center; it is imperative to understand those representations in order to untangle their knots, and to observe them in order to see beyond them. Résumé Le concept de ville-dortoir, longtemps présent dans les discussions sur São Gonçalo-RJ, provoque, lorsqu’il devient évident, une absence: les différentes possibilités de représenter la ville sont éclipsées par l’omniprésence de ce concept. Nous cherchons à aborder les implications de la cristallisation de certaines représentations qui se forment autour du concept de ville-dortoir. Lorsqu’un concept cesse d’être une médiation entre le vécu et le conçu, il peut se cristalliser et provoquer un blocage de la compréhension. Au cours de cet article, nous récupérons quelques utilisations du concept de ville-dortoir dans la région métropolitaine de Rio, en les confrontant à quelques informations de la réalité actuelle de la municipalité. Nous discutons ensuite des implications symboliques et matérielles de la cristallisation de ces représentations et leur rôle dans la production de l’espace urbain. Comme résultat de la recherche, nous avons conclu qu’il est nécessaire de faire émerger une compréhension qui va plus loin que la prépondérance du centre métropolitain; il faut comprendre les représentations pour défaire leurs nœuds, les observer pour pouvoir voir au-delà d’elles.

5G technology is beginning to be implemented, providing some pilot initiatives and significant development, deserving in the tourism area increased attention from tourism entities that may leverage its potential. In this chapter, the authors first consider the technological advances of 5G, presenting some aspects that tend to be leveraged, namely augmented reality and virtual reality. Next, we explain in general terms the contributions that 5G technology can make to tourism and we present in more detail its performance in the area of transportation, accommodation, events, and cultural tourism. The authors also identify and describe some cases, which may appear as pilot experiences, but which are already successful manifestations of 5G technology and representations of its potential. Thus, the main objectives of this document, through an accessible text, are: (i) to raise the awareness of tourism managers, with theoretical concepts and practical examples, for the need to develop 5G initiatives; (ii) to provide academia with further support for possible empirical research.

Buildings play an active role in the global energy consumption and are required to not only minimize their energy use, but also generate energy in a sustainable manner. The integration of renewable energies in building elements can improve their overall performance, as they are able to replace common construction materials, while offering both electrical and thermal energy. The scope of this paper is to present the first results of an experimental study of a Building-Integrated Photovoltaic system combined with a water storage tank (BIPV-WS), a combined integration not extensively studied yet. Both layers are separated by a ventilated air cavity, and the thermal behavior of the system was analyzed experimentally in real functioning conditions. The water tank performs as a thermal storage, maintaining a regular temperature of about 20-30 degrees C during a typical winter day of Lisbon for a period of 11 h. Moreover, through the ventilation of the air cavity, the heat provided by the solar panel was naturally recovered to the indoors of the building, while keeping the temperature high enough to heat up the water. During summer, the ventilated BIPV-WS enabled beneficial nocturnal heat loss while delaying diurnal space heating. info:eu-repo/semantics/publishedVersion
