In multicentric and increasingly complex urban regions, a city centre reinvents itself. In the case of Porto, tourism was essential for its “Baixa” renaissance. A relevant increase in visitors meant also a dramatic increase in real estate prices and significant land-use change. In field interviews, retailers noticed a “new life” before COVID-19 arrived, remarking on the positive role of tourism on urban rehabil...

One of the leading age-related changes affecting most older adults is the worsening of sleep quality. The literature suggests that the reduction of daily physical activity and increased frequency of daytime sleep periods in older adults are some of the main events contributing to the reduction in sleep quality, which may also negatively affect cognitive function. Considering this, it is expected that older peop...
This paper presents a comprehensive examination of the microstructure and mineralogy of the paper-like material found in Asian hornet nests (referred to as AHN P-LM) and the nearby tree leaves, utilising scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) and X-ray diffraction (XRD). The analysis conducted through SEM-EDS demonstrates that AHN P-LM is primarily composed of plant fragments...
O ninho da vespa asiática (NVA) tem despertado o interesse de vários investigadores de diversas áreas do conhecimento. Na perspetiva da construção, este ninho revela uma complexidade funcional, arquitetónica, construtiva, estrutural e material deveras interessante. Alguns trabalhos de investigação foram publicados recentemente sobre o estudo desta construção animal. De uma maneira geral, estes trabalhos debruça...
Introdução: Os cuidadores informais desempenham um papel crucial na prestação de cuidados a indivíduos com doenças crónicas ou incapacidades. Esta tarefa pode gerar uma sobrecarga física e psicológica significativa, impactando negativamente a qualidade de vida dos cuidadores.
O desperdício alimentar, uma forma de biowaste comum a nível global, é um dos maiores desafios de sustentabilidade que a indústria alimentar enfrenta. A indústria de frutas e hortícolas destaca-se neste contexto, sendo responsável por 25 a 30% do total, incluindo resíduos como cascas, sementes e bagaço [1,2]. A valorização deste tipo de resíduos constitui uma estratégia que visa transformar estes em produtos de...
Enquadramento – As doenças crónicas, e em particular a asma, no decorrer da sua evolução natural adquirem características que no seu corolário são vistas como um fardo para as pessoas que as vivenciam. Devido às necessidades de cada pessoa com asma, ao longo do percurso da doença vão haver consumos desequilibrados de cuidados em saúde. Objetivo – Mapear a evidência científica sobre as necessidades da pessoa adu...
We consider a modified Lotka–Volterra model applied to the predator-prey system that can also be applied to other areas, for instance, the bank system. We show that the model is well-posed (nonnegativity of solutions and conservation law) and study the local stability using different methods. Firstly, we consider the continuous model, after which the numerical schemes of Euler and Mickens are investigated. Fina...
Green republicanism can be described as a subset of republican political theory that aims to promote human flourishing by ensuring a non-dominating and ecologically sustainable republic. It expands the republican idea of social interdependence with the natural world, and therefore requires promoting and protecting the autonomy within those interdependencies. As such, green republicanism will focus on moving awa...
