    An approach to the implementation of Low Impact Development measures towards an EcoCampus classification
    2019-02-15 - Matos, C.; Briga Sá, A.; Bentes, Isabel Maria da Assunção de Marta...; Pereira, S.; Bento, R.
    Impervious cover has important hydrologic impacts, namely the increased runoff volume and peak discharges in the rainwater network, which can lead to significant consequences like rapid urban floods with social, environmental and economic implications. LID (Low Impact Development) consist of distributed runoff management measures, like green roofs, pervious pavements, waterways covered with vegetation and filter trails, among others, that seek to control stormwater in the origin, reducing imperviousness. These solutions avoid increased runoff rate and volume, increase infiltration and groundwater recharge. The main goal of the research work here presented is to study the hydrological impact of LID's in UTAD (University of Trás-os-Montes e Alto Douro) campus, which is an institution focused on sustainability, since it has defined in its Strategic Plan to achieve, in a near future, an EcoCampus classification. To achieve the proposed goal, the campus area was studied in detail in order to evaluate the technical possibility of LID's implementation. A peak discharge comparison was made between the current situation and the one with LID's implementation, using the rational method. The results showed that peak discharges reduction between 68 and 95% may be achieved with LID solutions in UTAD campus.

    A land-cover based urban dispersion indicator suitable for highly dispersed, discontinuously artificialized territories: The case of continental Portugal
    2019-06 - Urbieta, Pablo; Fernandez, Emilio; Ramos, Luís; Méndez Martínez, Gonzalo; Bento, Ricardo Jorge E Silva
    Land-cover based indicators assessing the effect of the magnitude and spatial patterns of the artificialization process, including urban sprawl, barely consider the impact of the discontinuous spatial distribution of the artificialized built-up areas. In this study, we propose a new urban dispersion indicator, which incorporates the characteristic dynamics of the discontinuous urban artificial land cover class, characteristic of scarcely populated and highly dispersed territories, such as is the case of Continental Portugal. The indicator is based on the premise that the more built-up area, the higher the uptake of constructed area in a discontinuous pattern and the more dispersed this built-up area, the lower urban sustainability of the territory. Given that the minimum cartographic unit in Corine Land Cover (25 ha) is typically higher than most of the discontinuous urban patches in these territories, in this research we used national land use data from Portugal with a minimum cartographic unit of 1 ha. The values calculated for this indicator show that the level of urban dispersion of continental Portugal increased by 14.2% in the 1990–2007 period. The artificialization process was geographically heterogeneous with notable differences being observed between regions and also along the urban to rural and coastal to hinterland gradients. The temporal changes in the indicator allowed the identification of distinct artificialization patterns: diffusion, sprinkling and coalescence, which were interpreted on the basis of the evolution of the artificialization process. The values derived from this indicator were related with two main environmental impacts associated with the artificialization process: the loss of arable land and the decrease in the carbon sequestration capacity of the territory. The proposed indicator can be a useful tool to monitor and evaluate the impacts of different public policies with a direct impact on land artificialization, as well as on the territorial and urban planning processes, whether at the national, regional or municipal level, allowing more detailed and consistent spatial analyses and diagnoses of urban sustainability to be undertaken.

    Fibrous structures in augmentation for rotator cuff repair: an experimental comparison
    2018 - Peixoto, Tânia; Pereira, Fábio A. M.; Silva, Paula L.; Guedes, Rui M.; Torres, João; Lopes, Maria A.
    Background and purpose: Rotator cuff tendon (RCT) injuries are difficult to manage as current strategies do not restore tissue functionality. Driven by this market demand, several devices have been developed during the last years, however, to develop a structure that properly mimics the mechanical performance of the native tissue remains a challenge. This way, in this work we study a set of design criteria for a synthetic graft development for RCT repair and reconstruction, in order to achieve a structure with an adequate mechanical performance to substitute the damaged tissue, and that can also act as a scaffold, allowing and guiding tissue ingrowth.

    Characterization of water and energy consumptions at the end use level in rural and urban environments: preliminary results of the ENERWAT Project
    2019-01-09 - Matos, Cristina; Cunha, António Manuel Trigueiros Da Silva; Pereira, Francisco; Gonçalves, Arminda; Silva, Elisabete; Pereira, Sandra; Bentes, Isabel Maria Da Assunção De Marta...; Faria, Diana; Sá, Ana Briga
    The characterization of water and energy consumptions is essential in order to define strategies for their rational use. The way these resources are used in households is the path for efficient and rational management, interdependent from each other. It is believed that there are significant differences between the patterns of water and energy consumption in rural and urban areas, where influencing factors should also be identified. This article aims to provide some preliminary results of a research project named ENERWAT, with the main goal to characterize the relation between water and energy consumption at the end use level for urban and rural environments. One of the goals of the aforementioned project was the design, application, and results analysis of a survey, in order to find the main differences in the water and energy consumptions at the end use level and the factors that influence it in urban and rural households. A total of 245 households participated in the research during 2016 (110 urban dwellings and 135 rural), responding to questions on their family composition, dwellings characterization, water and energy consumption habits, and conservation behaviors of these resources. The project also includes the instrumentation and monitoring of dwellings in rural and urban environments to quantify the water consumption and related energy consumption. This stage is still in progress and includes in situ measurements of nine different households (four in rural and five in urban environments) during at least one year. In this article, some of the results obtained by the survey application and the in situ measurements are presented. Despite the large number of data and the associated complexity, it can be concluded that the joint analysis of the results allows identification of a connection between water and energy consumption, as well as a household’s consumption patterns.
