How do renewable energy communities impact household energy consumption?
Conceição, Maria Inês; Cunha-e-Sá, Maria Antonieta; Póvoa, InêsRenewable Energy Communities (RECs) are increasingly recognised as key instruments for a just energy transition. Yet evidence on their impact on households’ energy behaviour remains limited. This study focuses on the Agra do Amial REC, located in a deprived neighbourhood in Porto, Portugal’s second largest city, and assesses its impact on electricity consumption and expenditures. Using high-frequency (hourly/da...
Analysing Gastric and Intestinal Myoelectric Activity Across Digestive States w...
Sousa, Sara Raquel GomesElectrogastrography (EGG) is a non-invasive technique used for recording the myoelectri- cal activity of the stomach and intestines. Despite its clinical potential, its application as a diagnostic tool for gastrointestinal pathologies remains limited, in part due to the lack of standardized methodologies and limited understanding of its signal’s characteristics across physiological states. This thesis aims to c...
Open and Sustainable Innovation in Port Ecosystems
Sabino, Maria Rosilene; Cabrita, Maria do Rosário; Mendes, Ana de Jesus; Pinho, Tiago; Castro, MarcelaPorts are increasingly required to respond to environmental regulation, digital transformation, and demands for more sustainable logistics systems. Although research on smart ports, green ports and innovation ecosystems has expanded, less attention has been given to how Open and Sustainable Innovation is enabled, constrained and institutionalised within public port authorities. This study examines this process ...
Tissue-specific expression and regulation of congenital disorders of glycosylat...
Neves, Cátia J.; Gomes, António; Lourenço, Rita A.; Barbosa, Mariana; Grosso, Ana R.; Videira, Paula A.Congenital disorders of glycosylation (CDGs) are rare metabolic diseases characterized by clinical heterogeneity, yet the molecular basis for their tissue-specific manifestations remains poorly understood. Because affected tissues are rarely accessible for biopsy, the baseline transcriptional and regulatory landscape of CDG-causative genes in healthy human tissues offers a valuable, complementary perspective on...
A Idade do Ferro na cidade de Lisboa: o sítio arqueológico da Rua das Flores, C...
Santos, Joana Sofia Rodrigues dosAs diversas intervenções arqueológicas no Castelo de São Jorge, na freguesia de Santa Maria Maior de Lisboa, permitiram a identificação de sucessivas estruturas, juntamente com um conjunto considerável e vasto de materiais, associados com um povoado da Idade do Ferro, balizado entre o século VII a.C. e os finais do século II a.C., data da chegada dos primeiros contingentes militares romanos. Com o decorrer das ...
The Governance of Expression Under Algorithmic Logic: A Roadmap to Safeguard Pu...
Silva, Isaura SalgadoInitially celebrated as enablers of democratic expression, social media platforms have paradoxically become powerful gatekeepers, exerting unprecedented forms of control over speech that would have been unimaginable in the pre-digital era. Amid rising concerns over their role on social fragmentation—from youth mental health crises to electoral instability—regulators have begun scrutinizing these mechanisms of s...
The role of Management Accounting in the Process of Innovation: a field work pe...
Canelas, João Manuel DuarteRecent accounting literature (e.g. Granlund and Taipaleenmäki, 2005; Davila, Foster & Oyon, 2009) suggests that Management Control Systems can influence the process of innovation, especially when they are used interactively. Such work constitutes a rupture with the traditional and diagnostic vision of control where Management Control Systems only act at the process of strategy implementation, limiting their rol...
High atom-economy low-temperature depolymerization of polyethylene terephthalat...
Araujo, Hugo Q.; Martins, Diogo; Goncalves, Joao; Matos, Ines; Ventura, Marcia; Diniz, Mario; Tomazio, Diana; Branco, Luis C.; Lapa, NunoThis study investigates the low-temperature depolymerization of polyethylene terephthalate (PET) using near-stoichiometric choline hydroxide (ChOH) in methanol, assisted by dichloromethane (DCM) or dimethoxymethane (DMM) as co-solvents. The DCM-assisted system enables rapid apparent PET depolymerization within 30 min under mild conditions, whereas the DMM-assisted system achieves hydrolysis within 20 h at room ...
A Framework-Based Evaluation of Open Data Platforms in European Ports
Freitas, Lucas; Mendes, Ana J.; Castro, Marcela; Pinho, TiagoOpen data platforms (ODPs) are emerging as strategic infrastructures for smart port development within the European Union, yet there is limited research offering integrated approaches to evaluate their performance across technical, operational, and regulatory dimensions. To address this gap, this study develops an analytical framework combining four complementary perspectives: open data platform design, FAIR (F...
Microfloresta como infraestrutura verde de adaptação sustentável às alterações ...
Santos, Arida ChagasA presente dissertação analisa o potencial das microflorestas enquanto infraestruturas verdes de adaptação sustentável às alterações climáticas em contextos urbanos, tomando como referência empírica os casos de Almada (Portugal) e Belo Horizonte (Brasil). Parte-se da premissa de que o crescimento urbano, resultante de processos acelerados de urbanização, tem amplificado os impactos ambientais e sociais nas cida...
