Una historia de diseño del cartel en Portugal del siglo XVII al XIX

To write an history of the design of the poster about three centuries in Portugal allows to understand how this artefact has changed over time. Usually, the result does not configure the reasons that gave rise of the poster, because they are not always visible and so, they don’t illustrate the reality in which they emerged. This article reveals a series of factors associated not only with the historical events, as well the adjacent constraints to design a poster. Portugal has in some cases a particular path with regard to the design history of the poster. To reveal this history the adopted methodology to explain this narrative will refer the technology (paper production and selection, printing techniques, use of different materials), programme (categories of posters – political, cultural and commercial – in parallel with the historical events) and authorship (anonymous and identified posters, styles and references). The article is divided in four sections, where each section is related to one century. The set of examples collected contribute to the knowledge of the history of design of the poster in Portugal.Contar una historia del diseño del cartel durante tres siglos en Portugal permite entender cómo ha cambiado este artefacto durante el tiempo. Generalmente, el resultado no configura los motivos que lo originaran, ya que no siempre son visibles y por lo tanto no ilustran la realidad en la que fueron diseñados. Este artículo revela una serie de factores asociados no solo con los acontecimientos históricos, así como las limitaciones asociadas a la realización de un cartel. Para explicar esta narrativa la metodología adoptada referirá la tecnología (papel, producción y selección, técnicas de impresión, el uso de diferentes materiales), programa (categorías de cartel –políticos, culturales y comerciales– en paralelo con los acontecimientos históricos) y autoría (carteles anónimos e identificados, estilos y referencias). El artículo se divide en tres secciones, dedicadas a cada siglo tratado. El conjunto de ejemplos recogidos contribuye al conocimiento de la historia del diseño del cartel en Portugal

The use of fitness apps on customer satisfaction and retention: the fitness centres context

The objective of this study is to analyse the use of fitness centre apps and its influence on customer satisfaction and retention. In this sense, three studies were conducted, one systematic review and two cross-sectional, quantitative studies. The systematic review was carried out using the PRISMA method. The other two studies used the extended unified theory of acceptance and use of technology (UTAUT2) as a base model. All hypothesised relationships used partial least squares structural equation modelling (PLS-SEM), with data from 1,678 fitness customers from Portugal. The results highlighted the importance of the study of technologies in customer retention. The results also support the ability of UTAUT2 in predicting the customer´s intention to use the fitness centre and that the use varies according to customer characteristics. Behavioural intentions are positively related both to the use behaviour of the fitness centre app and to customer overall satisfaction. The suggested that fitness centres invest in the use of a good application, since their use is related to customer overall satisfaction and, thus, indirectly with retention, which benefits the fitness centres

The design of Portuguese political poster: two politics, two discourses

This paper aims to present a history of the Portuguese political poster in two key moments of twentieth century Portuguese politics, the moment of the establishment of the ‘Estado Novo’ (or New State) i.e., Salazar’s authoritarian and quasi-fascist dictatorship which ran from 1933- 1974, and the period of the Revolution of April 25 of 1974, which overthrew the previous regime. The two distinct ideologies give rise to two contrasting modes of visual discourse. This is particularly evident in posters made in the two revolutionary moments (1933-1938 and 1974-76). These reveal ruptures in relation to the visual discourses of posters made in the periods before and after these dates. The paper shows how the posters offer a particular kind of lens on the two contrasting revolutionary moments; a way of looking at how the two revolutions attempted to communicate to and connect with the Portuguese people in whose name and one whose behalf—ostensibly in the first case, substantively in the second—the revolutions were undertaken. In terms of the understanding of activism and revolutionary graphics a contribution is made to understanding how revolutions of left and right contrastingly 2 present themselves—and how, through the use of poster, they evoke or extol particular kinds of political subjects and political orders

Finite element analysis of femoral components after in-cement revision

A técnica de cimento-em-cimento é um procedimento de revisão da artroplastia total da anca em que uma nova prótese é aplicada numa manta de “cimento velho” bem fixa ao do fémur. Excelentes resultados têm sido reportados em diversos estudos clínicos a respeito da estabilidade dos componentes femorais após alguns anos da cirurgia. Contudo, poucos estudos biomecânicos têm sido apresentados, envolvendo a utilização desta técnica. Assim, este trabalho pretende contribuir para a compreensão da análise mecânica, nomeadamente avaliar a distribuição de tensões e a estabilidade de longo prazo das estruturas deste tipo de implantes, colocados com recurso à técnica de cimento-em-cimento. O estudo numérico implementado recorre ao método dos elementos finitos, num total de seis modelos que simulam várias condições de revisão a partir desta técnica. Dois modelos de artroplastia primária, com próteses do tipo force-closed de diferentes dimensões, foram desenvolvidos de modo a servir de base para a criação dos modelos representativos da cirurgia de revisão. O recurso a um método de validação qualitativa permitiu comparar os resultados obtidos com os presentes na literatura. O trabalho centra-se no estudo da influência das variações nas espessuras de cimento, e da prática da substituição da haste femoral por outra de menores dimensões. Assim, apesar de possuírem hastes de mesmo tamanho, todos os modelos da cirurgia de revisão são diferentes entre si, e comparam, simultaneamente, a espessura de cimento novo ao redor da haste e as dimensões do cimento velho. Duas análises estáticas foram executadas para cada modelo, uma considerando a interface entre cimento e haste perfeitamente fixa e outra, modelando o contato com descolamentos de interface, de modo a simular o afundamento da haste. Os resultados obtidos mostraram que a influência da espessura de cimento e da mudança de uma haste por outra de menor tamanho na distribuição de tensões pode ser considerada desprezável. Na avaliação da estabilidade, o estudo evidenciou maior estabilidade no cimento velho.The in-cement technique is a procedure in which a new stem is cemented into a well fixed cement mantle inside the femur bone, during revision total hip arthroplasty. Excellent outcomes have been reported in several clinical studies regarding the stability of the femoral components, after revision total hip arthroplasty using the in cement technique. Aiming to evaluate the stress distributions and the long-term stability in such implants’ structures, the finite element method was employed in static simulations on a total of six models that were designed to represent implanted femurs postoperatively. The influence of the variations in the mantle thick-nesses in the revision models, and of the practice of replacing the femoral stem by another with shorter size on the biomechanical results was also considered in the present investigation. Therefore, all revision models were designed to have stems of same size but to differ from each other when comparing, simultaneously, the new mantle thickness around the stem and the dimensions of the well-fixed mantle. Two primary hip replacement models, with force-closed stems of different body sizes, were designed to serve as a basis to create the revision models, where one of them was used verify the validity of the models created in this work, through a qualitative comparison between the results from the static studies with the ones from a previous publication. Also, the bonded and debonded classic interfacial interactions were considered for the cement-stem interface in all models, where the debonded stem resulted in the increase of the tensile and compressive stress levels across the implant components. The differences in the mantle thicknesses and the change of the femoral stem by another with smaller dimensions were found to exert negligible effects on the stress distributions. In the stability analysis, it was concluded that the well-fixed mantles are the stablest
