Water-induced modifications in the physicochemical and structural properties of...
Monteiro, Hugo; Santos, António; Sarmento, Célia; Farinha, Andreia; Witkamp, Geert Jan; Paiva, Alexandre; Ferreira, Ana Sofia D.; Duarte, Ana Rita C.Deep eutectic solvents (DESs) have attracted considerable attention as sustainable alternative solvents in a wide range of applications. A key property of these mixtures is their viscosity, which can, for some systems, be too high for practical applications. Adding water lowers the viscosity by replacing hydrogen bonds between the components, with those involving water. Thus, a key factor in various application...

Stability and changes in loneliness profiles across adolescence: The effects of...
Ribeiro, Olívia; Rubin, Kenneth H.; Santos, AntónioAdopting a person-centered approach with longitudinal data, our study examined the stability and transitions of loneliness profiles across three consecutive years, during adolescence. We also explored the lasting effects of loneliness and the role of intraindividual characteristics—sex, self-worth, social acceptance, friendships competence, and social withdrawal—in predicting transitions between profiles. Data ...
Familial Hypercholesterolaemia and the Risk of Cardiovascular Events.
Conchinha, André; Rodrigues, Afonso; Pack, Tiago; Cunha, Sofia; Santos, AntónioFamilial hypercholesterolaemia (FH) is an autosomal dominant genetic disorder, characterised by markedly elevated levels of low-density lipoprotein cholesterol (LDL-C) from birth, which confers a substantially increased risk of premature atherosclerotic cardiovascular disease (ASCVD). Pathogenic variants primarily occur in the genes encoding the low-density lipoprotein receptor (LDLR), apolipoprotein B (ApoB), ...
Guidelines for the Diagnosis and Treatment of Uncomplicated (Non-Lymphogranulom...
Andrade, Pedro; Azevedo, Jacinta; Lisboa, Carmen; Fernandes, Cândida; Borrego, Maria José; Borges-Costa, João; Reis, Joel; Santiago, FelicidadeChlamydia trachomatis infection is the most prevalent sexually transmitted bacterial infection in the world. Being associated with a large number of asymptomatic carriers, the diagnosis is frequently challenging and requires appropriate laboratory testing. In Portugal, the incidence of the disease has been consistently increasing in recent years, meaning that special awareness is required for case identificatio...
Investigating contamination indexes and mobility processes in mine-stream sedim...
antunes, Isabel Margarida; Carvalho, Paula; Albuquerque, Maria Teresa; Santos, AntónioThe mining industry plays a crucial role in today’s society due to the growing demand for strategic materials. Nevertheless, it is essential to acknowledge the signi cant threats posed to the environment by mining operations. Striking a delicate balance between resource needs and environmental protection is imperative.

Factors affecting cloud computing adoption in the education context: systematic...
Santos, António; Martins, José; Gonçalves, Ramiro; São Mamede, Henrique; Branco, Frederico; Pestana, Pedro DuarteThis systematic literature review investigates the factors influencing cloud computing adoption within both educational and organizational settings. By synthesizing a comprehensive body of research, this study finds and analyzes the determinants that shape the decision-making process about cloud technology adoption. Security, cost-effectiveness, scalability, interoperability, and regulatory compliance are exami...
The geochemical behavior of Pb and Zn in waters and stream sediments around a f...
Carvalho, Paula; Antunes, I.M.H.R.; Albuquerque, Maria Teresa; Santos, AntónioIn Portugal, ore mineral exploitation has left millions of tons of mining waste rich in metals in the environment. The former Várzea Pb-Zn mine is located in the Várzea dos Cavaleiros village, about 10 km from Sertã village and 65 km from Castelo Branco county, central Portugal. The Pb-Zn quartz vein with N10ºW; 75º SW orientation, 0.5-1.5 m thick, intruded the Neoproterozoic-Cambrian schist-greywacke complex. ...
Geo-accumulation indexes of trace elements in sediments from uranium environmen...
Antunes, Isabel Margarida Horta Ribeiro; Teixeira, Rui; Valente, Teresa Maria Fernandes; Santos, AntónioStream sediments are usually used as a tool for contamination evaluation. The studied area is an abandoned uranium mine located in Central Portugal, in a not steep area, with altitudes ranging from 360 to 380 m. Geoaccumulation index and contamination factor have been used in the as-sessment of the degree of contamination of stream sediments with toxic metals. The stream sediments are heavily to extremely conta...
