Exercise intensity agreement, need satisfaction, and exercise behavior: A sex-m...
Teixeira, D. S.; Andrade, A. J.; Faria, J.; Marques, P.; Bastos, V.; Rodrigues, F.; Sousa, A. M.; Pereira, H. V.Several theoretical frameworks have been used to understand exercise adherence. Basic psychological needs (BPN), grounded on self‐determination theory, have received large attention for this purpose. More recently, the hedonic theory and the assumptions related to the exercise characteristics (e.g., intensity) that can bolster positive affective responses have been revitalized. This study aimed to explore the a...

Monitoring sensors for urban air quality: The case of the municipality of Lisbon
Sarroeira, R.; Henriques, J.; Sousa, A. M.; Ferreira da Silva, C.; Nunes, N.; Moro, S.; Botelho, M. do C.Air pollution is a global issue that impacts environmental inequalities, and air quality sensors can have a decisive role in city policymaking for future cities. Science and society are already aware that during the most challenging times of COVID-19, the levels of air pollution in cities decreased, especially during lockdowns, when road traffic was reduced. Several pollution parameters can be used to analyse c...
Removal of tetracycline from contaminated water by Moringa oleifera seed prepar...
Santos, Andréa F. S.; Matos, M.; Sousa, A. M.; Costa, Cátia; Nogueira, Regina; Teixeira, J. A.; Paiva, Patrícia M. G.; Parpot, PierThe aim of this study was to evaluate tetracycline antibiotic (TA) removal from contaminated water by Moringa oleifera seed preparations. The composition of synthetic water approximate river natural contaminated water and TA simulated its presence as an emerging pollutant. Interactions between TA and protein preparations (extract; fraction and lectin) were also evaluated. TA was determined by solid phase extrac...
Comportamento dos preços de milho e feijão caupi no mercado do estado do Ceará
Sousa, A. M.; Barroso Neto, A. M.; Pinheiro, J. I.; Silva, V. B.; Nogueira, D. B.A agricultura de subsistência (geralmente milho e feijão caupi) é a atividade econômica mais importante na Região Nordeste, sendo a baixa disponibilidade de água o principal obstáculo para a produção agrícola. O estudo dos preços dessas culturas torna-se importante ferramenta de tomada de decisão por parte de produtores, sendo a análise de sazonalidade a metodologia mais empregada no âmbito de análise de preços...
MorphoCol: an ontology-based knowledgebase for the characterisation of clinical...
Sousa, A. M.; Pereira, Maria Olívia; Lourenço, AnáliaBackground One of the major concerns of the biomedical community is the increasing prevalence of antimicrobial resistant microorganisms. Recent findings show that the diversification of colony morphology may be indicative of the expression of virulence factors and increased resistance to antibiotic therapeutics. To transform these findings, and upcoming results, into a valuable clinical decision making tool, co...
Mining clinically relevant signatures from colony morphology images
Sousa, A. M.; Pereira, Maria Olívia; Lourenço, AnáliaHuman pathogenic bacteria are a common cause of infection and a recurrent disease complication, causing millions of deaths and bringing considerable costs to clinical facilities. Timely identification of the bacteria involved in infection is essential to clinical diagnosis and thus, disease management. Often, colony morphology observation complements conventional microbial diagnosis as means to detect phenotypi...
Pseudomonas aeruginosa diversification during infection development in cystic f...
Sousa, A. M.; Pereira, Maria OlíviaPseudomonas aeruginosa is the most prevalent pathogen of cystic fibrosis (CF) lung disease. Its long persistence in CF airways is associated with sophisticated mechanisms of adaptation, including biofilm formation, resistance to antibiotics, hypermutability and customized pathogenicity in which virulence factors are expressed according the infection stage. CF adaptation is triggered by high selective pressure o...
Extraction of agar from Gelidium corneum using an alternative heating technology
Rocha, Cristina M. R.; Sousa, A. M.; Esparinha, A. S.; Cardoso, B. I.; Vicente, A. A.; Gonçalves, M. P.Traditional polysaccharides extraction processes are often performed under heating which makes them time-, energy- and solvent-consuming. The aim of this work was to assess the possibility of using ohmic heating to replace conventional heating in the extraction of seaweed hydrocolloids. This technology is able to heat almost instantaneously the whole volume to be treated, using the ability that most materials h...
Biological features of Pseudomonas aeruginosa biofilms: time to rethink antimic...
Sousa, A. M.; Rodrigues, Alícia; Pereira, Maria OlíviaBacterial infections in cystic fibrosis (CF) lungs are generally associated with mucoid P. aeruginosa and small colonies variants (SCV). Previous works showed that several other colony variants were isolated from CF lungs showing as well resistance to antibiotics. Those variants until now devaluated may play a relevant role in CF population persistence to antibiotic therapies and immune defences. Phenotypic swi...
