A RECONFIGURABLE ELECTROMAGNETIC BANDGAP STRUCTURE FOR A BEAM STEERING BASE STATION ANTENNA

International audienceThe purpose of this communication is to present the works of a French Industry and Research sponsorized project (RNRT Project) named "BIP" [1]. The goal of this project was to design a beam steering multi-band (GSM/DCS/UMTS) base station antenna. After a presentation of the different partners, we will show how we would solved the problem of the beam steering antenna with a controllable Electromagnetic BandGap (EBG) structure and we will present the results of simulations and experiments in order to validate the concept

Digital Food and foodways. How online food practices and narratives shape the Italian diaspora

The article discusses the role of online food practices and narratives in the formation of transnational identities and communities. Data has been collected in the framework of a doctoral research project undertaken by the author between 2009 and 2012 with a follow-up in 2014. The working hypothesis of this article is that the way Italians talk about food online and offline, the importance they give to ‘authentic’ food, and the way they share their love for Italian food with other members of the same diaspora reveal original insights into migrants’ personal and collective identities, their sense of belonging to the transnational community and processes of adjustment to a new place. Findings suggest that online culinary narratives and practices shape the Italian diaspora in unique ways, through the development of forms of virtual commensality and online mealtime socialization on Skype and by affecting intra and out-group relationships, thus working as elements of cultural identification and differentiation

A História da Alimentação: balizas historiográficas

Os M. pretenderam traçar um quadro da História da Alimentação, não como um novo ramo epistemológico da disciplina, mas como um campo em desenvolvimento de práticas e atividades especializadas, incluindo pesquisa, formação, publicações, associações, encontros acadêmicos, etc. Um breve relato das condições em que tal campo se assentou faz-se preceder de um panorama dos estudos de alimentação e temas correia tos, em geral, segundo cinco abardagens Ia biológica, a econômica, a social, a cultural e a filosófica!, assim como da identificação das contribuições mais relevantes da Antropologia, Arqueologia, Sociologia e Geografia. A fim de comentar a multiforme e volumosa bibliografia histórica, foi ela organizada segundo critérios morfológicos. A seguir, alguns tópicos importantes mereceram tratamento à parte: a fome, o alimento e o domínio religioso, as descobertas européias e a difusão mundial de alimentos, gosto e gastronomia. O artigo se encerra com um rápido balanço crítico da historiografia brasileira sobre o tema
