- Importance of climate change manifestations and urban green areas on the potential expansion of ixodid vectorsPublication . Barbosa, Rui; Monteiro, Ana; Freitas, MarisaUrban development combined with climate change can trigger negative effects in the ecosystems. Although the recognized environmental benefits, the implementation of urban green areas can increase the number of habitats favorable to the spread of ixodid vectors, as well as to increase its contact with humans and animals, which may constitute a public health problem. Nowadays, to increase the effectiveness of health services intervention, is necessary to create multidisciplinary teams. In this context, geography, through Geographic Information Systems (GIS), plays a crucial role. This software contributes to operate and export geographic alphanumeric information in a global, regional, or local scale. The aim of this study was to conjecture the potential vulnerabilities of climate change and the expansion of urban green areas on the occurrence of ixodid vectors in urban environments. Besides, it is intended to demonstrate the application of GIS methodology in delimiting higher risk zones and to propose new locations for ixodid vectors surveillance. The study area was composed by four municipalities of Porto metropolitan zone (Northern Portugal). The study was divided into three topics: characterization of local climate conditions, climate forecasts as well as green areas, surveillance data of ixodid vectors in the study area, identification of susceptible and risk areas of ixodid vectors expansion. The expansion of vectors in urban area was confirmed, evidencing that climate change combined with urban green areas can result in an increased dissemination of ixodid vectors in urban environments, consequently, may increase the incidence of diseases transmitted by them. This study shows that GIS constitute a profitable tool for a more fruitful site demarcation of ixodid vectors monitoring, increasing the success of its capture in the free-living phase. The more active identification of risk areas will allow health services to take more effective measures.
- Liquid by-products from fish canning industry as sustainable sources of ω3 lipidsPublication . Monteiro, Ana; Paquincha, Diogo; Martins, Florinda; Queirós, Rui P.; Saraiva, Jorge A.; Švarc-Gajić, Jaroslava; Nastić, Nataša; Delerue-Matos, Cristina; Carvalho, Ana P.Fish canning industry generates large amounts of liquid wastes, which are discarded, after proper treatment to remove the organic load. However, alternative treatment processes may also be designed in order to target the recovery of valuable compounds; with this procedure, these wastewaters are converted into liquid by-products, becoming an additional source of revenue for the company. This study evaluated green and economically sustainable methodologies for the extraction of ω3 lipids from fish canning liquid by-products. Lipids were extracted by processes combining physical and chemical parameters (conventional and pressurized extraction processes), as well as chemical and biological parameters. Furthermore, LCA was applied to evaluate the environmental performance and costs indicators for each process. Results indicated that extraction with high hydrostatic pressure provides the highest amounts of ω3 polyunsaturated fatty acids (3331,5 mg L-1 effluent), apart from presenting the lowest environmental impact and costs. The studied procedures allow to obtain alternative, sustainable and traceable sources of ω3 lipids for further applications in food, pharmaceutical and cosmetic industries. Additionally, such approach contributes towards the organic depuration of canning liquid effluents, therefore reducing the overall waste treatment costs.
- Publicações BIM: IV pós-graduação em Coordenação BIMPublication . Martins, Adriana; Monteiro, Ana; Carvalho, André; Melo, Bruna Beppler; Siqueira, Carolina Gavron; Teixeira, Diogo; Gomes, Edson; Nunes, Fábio; Barbosa, Hélder; Assunção, Luiza; Castro, Madalena; Mota, Nuno; Vieira, Rui; Cabral, Sara; Marques, Sara; Ribeiro, Diogo; Vaz, Jorge Vieira; Pinto-Faria, José; Santos, Ricardo; Gavina, Rui(Excerto Prefácio)Os trabalhos aqui compilados têm origem nos relatórios apresentados pelos autores — enquanto estudantes— na unidade curricular de Projeto Integrador, da quarta edição do Curso de Pós-Graduação “Coordenação BIM” (Building Information Modelling) promovido pelo ISEP (Instituto Superior de Engenharia do Porto), pela ESAP (Escola Superior Artística do Porto) e pela BIM Academy de Barcelona, em 2023. Na sua génese, os relatórios foram o resultado de trabalhos de grupos, com a dotação temporal de cinco semanas, apresentados e defendidos publicamente, sobre temas relevantes escolhidos pelos próprios estudantes, no âmbito da Coordenação de Processos BIM. A escolha livre dos temas, nesta última unidade curricular do curso, mostra-se muito diversificada, desde a aplicação sobre um case-study, e de um modo mais ou menos sincrético, das aprendizagens adquiridas nas anteriores unidades curriculares, até à exploração de temas muito concretos com origem nos interesses específicos dos estudantes, sejam eles de âmbito profissional, académico ou pessoal. A organização deste livro reflete a organização sucessiva dos temas, tendo em conta a sua temática restrita, partindo dos elementos básicos de modelação, passando pela organização dos processos de coordenação e a sua aplicação em contextos específicos, como a eficiência energética ou a reabilitação do edificado, assim:
