- An insight into the surface properties of calcined kaolinitic clays: The grinding effectPublication . Gamelas, José; Ferraz, Eduardo; Rocha, FernandoThe present work aimed characterizing in a systematic way the surface of metakaolinitic materials produced by calcination of a kaolinitic clay at different temperatures and to study the effect of grinding on the surface properties of metakaolinitic materials. Using X-ray photoelectron spectroscopy, it was found for all materials a Si/Al atomic ratio close to 1, confirming the presence of the 1:1 clay structure. By inverse gas chromatography, an increase of the Lewis basic properties of the surfaces of metakaolinitic materials in comparison to the original clay was found, which was due to the condensation of hydroxyl groups in the structure of the clay. The grinding of the metakaolinitic materials afforded a decrease of the dispersive component of the surface energy () as well as an increase of the specific interaction with sterically hindered molecules, caused by the diminishing of the materials surface nanoroughness. The Lewis basic properties of the materials surface also increased with grinding. Noticeably, for all studied materials a good inverse relation could be found between the and the specific interaction of trichloromethane (but not with dichloromethane), showing the importance of surface nanoroughness on the adsorption process of bulky molecules.
- Análise dos projetos e das obras no Palácio Foz, em Lisboa, entre 1887 e 1904: contributo para a sua reconstituição arquitetónica e construtivaPublication . Moreira, Anabela Mendes; Serrano, InêsA caracterização arquitetónica e construtiva de um edifício é fundamental em qualquer processo de intervenção. A proficiência desses processos depende, em grande medida, do conhecimento profundo do edifício e da correta interpretação das alterações que nele se tenham operado. A reconstituição construtiva, sobretudo de edifícios mais antigos e que foram submetidos a maior número de intervenções no decurso do tempo, nem sempre é possível, dada a inexistência ou a insuficiência de registos escritos do seu projeto inicial, ou das suas sucessivas alterações. Existem, porém, exceções que se referem principalmente a edifícios com maior notabilidade, onde é possível revisitar o processo projetual, através de registos coevos, e, no caso de obras mais recentes, identificar e analisar os estratos referentes às várias intervenções, através da análise documental geralmente depositada em arquivos institucionais. Neste artigo procede-se à possível reconstituição arquitetónica e construtiva dos elementos do envelope (cobertura e paredes exteriores) de um dos edifícios mais distintos da cidade de Lisboa, o Palácio Foz, erigido na sequência do terramoto de 1755. O trabalho de pesquisa realizado focou-se na análise dos requerimentos submetidos pelo Marquês da Foz à Câmara Municipal de Lisboa no período compreendido entre 1887 e 1904. Os referidos requerimentos correspondem a pedidos escritos de alterações, ampliações e renovações construtivas solicitados pelo proprietário. Este estudo pretende identificar e datar as principais alterações arquitetónicas e construtivas realizadas no envelope do edifício, relativamente à construção inicial, enquadrando-as com as alterações urbanísticas da zona envolvente. Pretende-se, assim, contribuir para a caracterização da história arquitetónica e construtiva do edifício, explicitando a relação entre as práticas construtivas e o contexto urbano durante aquele período.
- And after the master's? Some issues regarding the access to the profession of conservator-restorer in PortugalPublication . Cruz, António João; Desterro, TeresaIn order to contribute to the knowledge concerning problems faced by those who complete a master’s degree in conservation-restoration and intend to enter the labor market, the Portuguese case is presented. Thus, the formative offer and the legislative requirements are introduced as well as a real situation in which the majority of works are treated by those who do not have sufficient education in conservation-restoration. The article also discusses the lack of visibility of conservator-restorers and the image they have as artists when they are recognized. It is argued that this image leads to restoration being considered an activity that is accessible to all, an idea that is fed by numerous short courses, volunteer programs, and even some undergraduate and graduate courses that do not meet the basic requirements of ENCoRE. Finally, the ways in which a conservator-restorer can enter the labor market as well as the changes that seem to be underway in this field are mentioned.
- Annunciation or Adoration? The workshop practice and the hesitations of a Portuguese mannerist painter revealed by infrared reflectographyPublication . Melo, Helena P.; Cruz, António João; Valadas, Sara; Candeias, AntónioThe examination with infrared reflectography of the Annunciation and the Adoration of the Shepherds, two panels from a dismembered altarpiece attributed to the mannerist painter Francisco João (doc. 1558–1595), revealed the first documented example in Portuguese painting of the overlapping of two underdrawing layouts, each with a different subject, in a single panel painting. The paintings were examined under visible radiation and infrared reflectography was used to investigate the underdrawing in terms of the materials, graphic layout and function. Results from a previous study on the ground layers and underdrawing materials of these paintings, obtained with the analysis of micro-samples with microscopic and spectroscopic techniques, were used in the context of this research. Infrared images revealed that the underdrawing of the Annunciation mostly corresponded to the painted image but that two subjects — Annunciation and Adoration — were drawn over the prepared surface of the panel depicting the Adoration. This discovery is the first example of this procedure in Portuguese painting. The comparison with a third panel attributed to the painter, depicting another version of the Annunciation, allowed for the discussion of relevant technical procedures such as the use of cartoons, the responsibility for each main stage of painting creation and the reality of labour conditions in a regional market. The results contributed with material evidence to the scarce information of archival nature about the working methods of Portuguese mannerist painters.
- Assistive Robotic Hand Orthosis (ARHO) controlled with EMG: evaluation of a preliminary prototype*Publication . Farinha, Diogo; Dias, Joao; Neves, Pedro; Pereira, Katia; Ferreira, Carlos; Pires, GabrielHand impairment severely limits basic activities of daily living (ADL). The use of motorized hand orthoses may provide enough functional assistance to perform basic tasks, such as grasping objects. Several prototypes have been proposed in the last decade, but there are still no solutions with the desired features regarding the weight, wearability and functionality. This paper describes the overall implementation of a prototype of an assistive robotic hand orthosis (ARHO) for object grasping, that can be triggered manually or by the detection of muscular activity in the forearm using surface electromyography (sEMG). The system is being specifically designed for a case study of a person with hemiplegia resulting from a peri-insular hemispherectomy. The proposed orthosis is a very preliminary but functional prototype, still far from the desired features mentioned above, but serves to show all the modules composing a low-cost implementation, and above all, to understand all the constraints and difficulties in designing such a system.
- Biblioteca Digital Ciarte: literatura histórica técnico-artística em portuguêsPublication . Cruz, António JoãoThe Ciarte Digital Library (http://biblioteca.ciarte.pt), recently created, has as objectives, on the one hand, to give access to the ancient technical and artistic literature in Portuguese through volumes in pdf format resulting from purposely carried out digital restoration and, on the other hand, to make available information about these fundamental sources both for the knowledge of ideas, techniques and materials from which works of art and other cultural assets are made, and for the interpretation of the data obtained through different methodologies of the Humanities or Sciences. The presentation made here, in addition to the Library's promotion for those interested in these sources that are difficult to access, also intends to expose the principles underlying it and the technical options taken, which may be useful for similar projects. The close and prolonged contact with the great diversity of works already digitised serves as a support for the proposed typological classification of this literature.

- Bridging Culture, Tourism, and Literature: The Short Videos of Saramago's Small Memories of AzinhagaPublication . Silva, Julio; Santos, Luis; Silva, Manuela; Cordeiro, João; Carmo, Ana do; Romana, Maria Barras; Caetano Domingos, Susana IsabelA arte, conforme definida por Leo Tolstoi (2013), é a atividade pela qual uma pessoa, tendo experimentado uma emoção, transmite-a intencionalmente a outros. A forte ligação entre o enquadramento geográfico e experiências do autor, despoleta a imaginação do leitor e a vontade de viver na primeira pessoa as experiências. Algumas obras literárias e autores que estimularam os leitores a viajar, por exemplo Stratford-upon-Avon, de William Shakespeare, contribuem para o desenvolvimento local. Outros artistas e formas de arte também exercem o mesmo efeito, César Manrique em Lanzarote com pinturas, esculturas e arquitetura, ou o livro de John Ronald Reuel Tolkien através do filme Senhor dos Anéis promovendo a Nova Zelândia. Turismo cinematográfico ou turismo induzido por filmes é definido como qualquer viagem motivada por cenário com o objetivo de visitação. Nem todos os turistas cinematográficos são motivados da mesma forma, alguns são motivados por cenário, circunscrito e específico, enquanto generalistas visitam regiões ou países (Gürkaya, 2010). O estudo atual visa desenvolver 8 curtas-metragens da obra literária As Pequenas Memórias (2006) do Prémio Nobel José Saramago, onde o autor descreve o seu local de nascimento e experiências da juventude. Este trabalho mais do que a expressão de arte audiovisual visa promover o turismo cultural através uma de ampla estratégia integrada de turismo regional. O potencial deste turismo para o desenvolvimento ainda não atingiu a maturidade. Todos os tipos de turismo são efémeros, assim como os filmes, pelo que qualquer estratégia desenhada que contempla tais soluções necessita de uma reinvenção regular a fim de garantir a sua sustentabilidade.
