- Deterioration of the “Quinta Nova Torres Vedras” wall tile panel – an analytical approachPublication . Triães, Ricardo; Santos, Luis; Coroado, João; Rocha, FernandoWall tile panels were commonly used in recreational open outdoors spaces in 18th Century noble houses I Portugal. The nature of their location and the lack of maintenance of such spaces, which lost their purpose during the 20th century, contributed to their natural deterioration. In order to preserve one such panel and facilitate the conservation treatment, it was removed from its location and transported to the facilities of the Polytechnic Institute of Tomar, Portugal. The interest in studying this particular panel was prompted by the advanced stages of deterioration observed in some tiles, where natural succession of biological colonisation and weathering were registered as some of the main deterioration causes. Furthermore, the advanced deterioration stages indicate that removal was a necessary action, as natural weathering would lead to its destruction. The study involved a thorough analysis of the environmental characteristics of the wall placement, the wall materials themselves, the mortar, the ceramic body and the glaze. The methodologies used involved microscopic and laboratory testing to evaluate the extent of lichen colonisation and its influence in the loss of glaze and posterior deterioration of the ceramic body. Results indicate that natural and environmental characteristics, combined with substrate typology and micro-organisms, contribute to accelerate the deterioration process, though appropriate techniques of preventive conservation can be used in specific panels or broader situations. This study will enable the development of innovative methodological and technical approach to the conservation problem here portrayed.
- Water quality monitoring in the Paul do Boquilobo Biosphere ReservePublication . Baptista, C.; Santos, LuisThe Paul do Boquilobo is an important wetland ecosystem classified by Unesco as a MAB Biosphere reserve also awarded Ramsar site status, representing one of the most important habitats for the resident nesting colony of Cattle Egret (Bulbucus ibis). Yet owing to its location, it suffers from human induced impacts which include industrial and domestic effluent discharges as well as agricultural land use which have negatively impacted water quality. The current study reports the results obtained from the introductory monitoring programme of surface water quality in the Nature Reserve to emphasize the detrimental impact of the anthropogenic activities in the water quality of such an important ecosystem. The study involved physicochemical and biotic variables, microbial parameters and biological indicators. Results after 3 years of monitoring bring to evidence a poor water quality further impaired by seasonal patterns. Statistical analysis of data attributed water quality variation to 3 main parameters – pH, dissolved oxygen and nitrates, indicating heavy contamination loads from both organic and agricultural sources. Seasonality plays a role in water flow and climatic conditions, where sampling sites presented variable water quality data, suggesting a depurative function of the wetland.
- E-waste Management in Portugal: Legislation, Practices and RecommendationsPublication . Marques, C. G.; Silva, VascoThe use of electrical and electronic devices has grown exponentially in the last years thanks to technological advances and its wide dissemination. Consequently, the number of obsolete equipment (electronic waste or e-waste) has also increased significantly, becoming a major problem for society. This paper deals with electronic waste and explains the concept and risks for the particular case of Portugal. Measures to reduce the problem such as legislation, education production R&D and social responsibility are also discussed. And finally, a survey is presented which was carried out in two Portuguese Higher Education institutions with a view to determining students' awareness, attitudes and opinions on this matter.
- Using Mobile Technologies in Education: A New Pedagogical Approach to Promote Reading LiteracyPublication . Marques, C. G.; Manso, António; Ferreira, Ana Paula; Morgado, FelisbelaThe acquisition of reading skills is decisive for the academic achievement of students. However, learning to read is a complex process. With this in mind, several attempts have been made to find new educational approaches to enhance students' reading motivation. Considering the enormous potential of ICT for education and training, we have developed a digital repository of teaching and learning materials and a multiplatform application that runs on mobile devices: Letrinhas. This information system was designed to promote the development of reading and to provide tools for monitoring and assessing reading skills against the curricular targets set by the Ministry of Education. Letrinhas was evaluated by specialists and users and a high level of satisfaction was observed among students and teachers as time and effort spent to consolidate reading is considerably reduced with this application. This evaluation also enabled to identify features that will be available in the future.

- Dome and Away: Logan's Run Post-Apocalyptic CityscapesPublication . Sol, HermíniaThe rapid growth of population has been a global concern for quite some time due to its severe environmental, poverty control and social instability implications. A concern that becomes even more acute if one is to accept the United Nations’ Population Division latest predictions that by 2050, more than two-thirds of the world’s population is to live in cities (United Nations 1). Despite not being new, the concept of smart city has, in recent years, acquired privileged status amongst city planners and imagineers all over the world due to the belief that its focus on innovation, technology, ecology and people’s well-being can contribute to a more sustainable urban paradigm (Cowley; Dameri; Lindner). Mostly, smart cities are fast becoming a tangible representation of the futuristic cityscapes which were, till recently, confined to science fiction literature and cinema. Thus, it is no wonder that these tend to be regarded as a sort of dream-come-true project with a strong emphasis on the notion that the products and mechanism generated therein will ultimately “ensure the ‘good life’” (Foley et. al. 84). Whether this premise is a hundred percent valid it remains to be seen as smart-city initiatives are still being put to the test. Yet, the dangerous implications of present-day societies’ blind faith and dependence on technology have been persistently tackled in science fiction texts since the 1950s. A fine example of one such text is Michael Anderson’s film Logan’s Run (1976), a dystopian account of the pleasures and perils of the inhabitants of a computer controlled domed city in a post-apocalyptic future scenario. As defended by several researchers (Bina et al.; Foley et. al.), science fiction’s speculative spectrum regarding architecture and urban planning is particularly relevant as it provides “alternative insights into what challenges lie ahead,” both in terms of “future ‘possibilities’ and ‘warning signals’” (Bina et. al. 167). Consequently, both material and imaginary cityscapes “mingle and resonate together in complex and unpredictable ways” (Graham 395) since they influence each other. Bearing all this in mind, this article will first consider science fiction’s impact in the conception of the city of the future. While doing so, it will also consider how the notion of city of the future often carries utopian overtones, only to see them degenerate into dystopian scenarios. Subsequently, it will examine the different architectural styles present in Logan’s Run and their intended symbolism. Lastly, it will look into some warning signs regarding the environmental and personal privacy challenges that come with living in a smart city.
- Creative tourism, cultural heritage and entrepreneurship: the project MICULTURAPublication . Chasqueira, Ânia; Pereira Triães, Ricardo; Lopes, EuniceThe sustained growth of tourism in Portugal, particularly in the Central region of the country, motivated the establishment of a project dedicated to the artistic production, as a way of appreciating endogenous resources and the cultural heritage. MICULTURA is the denomination of a business project that arises in response to the growing demand for creative tourism, based on experiences inspired by the cultural and historical identity of the region. The development of the project MICULTURA had as its starting point the carried out survey on motivating tourists in the acquisition moment of souvenirs during the visit to a certain patrimonial resource. There was a lack of supply of differentiated goods on these same Another relevant project was also responding to the search of genuine and close experiences of the visited places, through the traditional techniques of artistic production, also valuing the endogenous resources and the tourist attraction of the region. Despite of being recent, this project has been designed in the region through the establishment of differentiating products before the traditional attraction, as well as the partnerships' establishment aimed at promoting tourism development in the Central region, as well as interacting with other audiences, namely the school and the senior audience.
- Combination of various solid wastes with fragmented limestone as filler for constructed wetlands used for wastewater treatmentPublication . Mateus, D. M. R.; Graça, Nuno; Alves, Ana; Pinho, Henrique J. O.This study aims to contribute to the development of eco-efficient constructed wetlands through the concept of circular economy and the use of waste to treat waste Combinations of five solid wastes were evaluated as filler materials for CWs used for wastewater treatment To evaluate the combined capability of the waste materials to wastewater treatment, five sets of unplanted lab-scale CWs were established The CWs were operated in a discontinuous mode for three successive fill and drain cycles The highest COD removal rate was obtained for a CW filled with limestone and cork waste 90.3+/-0.9%. The highest total nitrogen removal rate was obtained for a CW filled with limestone and clay brick fragments 84.8+/-0.1%. Total phosphorus removal percentage of 91.8+/-0.1% was achieved for a control CW filled with limestone It was observed that layer packed solid waste combination fillings are adequate in improving COD removal in limestone based CWs, and that all but the limestone snail shells filling have a very good performance for total nitrogen and total phosphorus removal from wastewater.
- Eggshell waste to produce building lime: calcium oxide reactivity, industrial, environmental and economic implicationsPublication . Ferraz, Eduardo; Gamelas, José A. F.; Coroado, João; Monteiro, Carlos; Rocha, FernandoEggshells wastes are produced in huge amounts worldwide. The recycling or valorization of this waste, which otherwise is usually disposed in landfills, represents an opportunity within a circular economy perspective. In the present work, the potential of chicken eggshell waste to produce calcitic lime was explored. After collection from an industry supplier, the waste was thoroughly characterized for its mineralogical, chemical, and thermal properties. The material was calcined at 1000 °C, and the obtained calcium oxide was evaluated for its reactivity in wet slaking tests. Comparison was made with commercial limestone used as reference. It was found that the calcium oxide from eggshell waste belonged to the most reactive class (R5—60 °C within 10 min), the same of the calcium oxide from limestone. However, different times were obtained to reach 60 °C (25 s and 4:37 min:s) and for 80% of the reaction (28 s and 5 min) for calcium oxide from limestone and eggshell waste, respectively. The lower reactivity of calcium oxide from eggshell waste was related to its larger size particles with smoother surfaces and lower specific surface area in comparison to limestone calcium oxide. Industrial, environmental and economic implications concerning the use of this waste to produce lime were also evaluated. The eggshell waste could be all consumed at an industrial scale in Portugal allowing for approximately 2.6% partial substitution of limestone in a lime factory.
- Cultural Mapping as a regeneration tool for sparsely-populated regionsPublication . Carvalho, Cláudia Pato; Sol, Hermínia; Oosterbeek, Luiz; Caron, LaurentDemographic sparsity poses major challenges to policy makers, essential service providers, as well as economic and cultural activity actors alike. Often equated with remoteness, rurality, and in certain cases, with harsh climate conditions these regions are frequently perceived as unattractive. This unattractiveness furthers their peripheral status and weakens their economic power. The fact that remoteness has a negative connotation prevents people, in general, from understanding that remoteness is not only about challenges, but also about opportunities. Those opportunities may emerge from a process of cultural mapping that can evaluate a community's uniqueness and strengths. In other words, periphery can also be about exquisite landscape and history, stories of resilience, as well as exceptional fauna and flora. Therefore, cultural mapping in sparsely populated regions can help promote local capital empowerment, and thus, contribute to a region's regeneration. As an example of this ambitious premise, two ongoing culturally related projects -- ARTERIA and MOVTOUR (with the activities Journeying the Screen I & II) -- will be used to illustrate an attempt to achieve this goal.
