Technic Praxis learning: A design studio embedding digital and physical knowledge

Following the recent development in digital technology and the emergence of sustainability as a crucial socio economic concern there is an increasing attention in interactive prototyping as an answer to the new architectural paradigm of the 21st century. Architecture schools are creating digital fabrication laboratories to provide their students the skills to support new learning processes and scientific innovation linked to this new challenge. This paper describes the results of a pilot experience held by an interdisciplinary Lisbon Workshop “Discursive Wall – a Living System” held at the Vitruvius FabLab-IUL.info:eu-repo/semantics/publishedVersio

A living system - Discursive wall

We feel and perceive the built environment through our senses and our body's interactive movement (Diniz 2008). In this paper we propose a DiscursiveWall that physically responds to movement, interacting spatially and temporally with the environment and its inhabitants. In addition, we intend to solve spatial acoustical issues related to sound reverberation. Based on the theory of Autopoiesis (Maturana & Varela 1980), the discursive wall acts as a self producing system. In response to movement sensors installed in the room, the cork surface elements of the wall move back and forth. Therefore, the inhabitants of the room make the wall mutate continuously, thus redesigning itself. This is produced by several components like sensors, bearing systems and test motors. A set of arduinos processes and distributes the information received from the sensors and receives back the animation data generated by Grasshopper and Firefly (plug-ins for Rhino software). The methodology that supports this prototype explores the real possibility of the architecture to enter into a direct dialog with its inhabitants and surrounding space.info:eu-repo/semantics/acceptedVersio

A aplicação de algumas provas serológicas e cutâneas no diagnóstico de certas helmintíases

RESUMO Apesar de o diagnóstico da maioria das helmintíases se basear principalmente na pesquisa de ovos ou de larvas dos parasitas, há, nalguns casos, necessidade de recorrer a provas serológicas e cutâneas, perante a negatividade ou impraticabilidade das primeiras pesquisas. Neste trabalho dá-se conta dos resultados obtidos com a aplicação da reacção de fixação de complemento e intradermorreação em indivíduos parasitados e em indivíduos sãos, tanto para a Fascíola hepática como para o Schistosoma bovis. Nota — Com os antígenos preparados por nós e utilizados no presente trabalho estão a proceder a intradermorreacções, em indivíduos doentes da respectiva parasitose, particularmente de esquistossomíase, os Srs. Prof. F. Cruz Ferreira (doentes da Guiné Portuguesa) e Dr. Viana de Meira (Cabo Verde). Destes resultados, bem como de outros nossos, daremos notícia posteriormente.RÉSUMÉ Le diagnostic de la majorité des helminthiases est basé, surtout, sur la recherche des oeufs ou des larves des parasites mais, malgré cela, on a besoin, parfois, de recourir à des épreuves sérologiques et cutanées, dans le cas de négativité ou d'impraticabilité des premières recherches. Dans ce travail on présente les résultats obtenus avec l'application de la réaction de fixation de complément et intradermo-réaction, dans des individus malades et dans des individus sains, tant pour la Fasciola hepatica que pour le Schistosoma bovis.SUMMARY Although the diagnosis of the majority of the helminthiasis is based upon the finding of the eggs and larvae of the parasites, in some cases, when those tests arc negative or non-practicable, it is necessary to employ serological as well as cutaneous tests. The results obtained with the complement fixation test and intradermal tests for Fasciola hepatica and Schistosoma bovis performed in both parasitized and healthy individuals are reported in this paper.info:eu-repo/semantics/publishedVersio
