Flexographic Printed Flexible Thermochromic Stickers for Smart Sensing Applicat...
Morais, M.; Figueira, J.; Corvo, M. C.; Peixoto, M.; Oliveira, Duarte Belo de; Gonçalves, A.; Fortunato, E.; Martins, R.; Carlos, E.; Pinto, J. V.The growing demand for thermochromic materials in areas such as food packaging requires the development of fast-response and extended-life materials. The use of metal cation-ionic liquid complexes is increasing due to the easiness to tailor their properties, leading to changes in thermochromic response. This work presents the synthesis and introduction of thermochromic 1-butyl-3-methylimidazolium chloride and 4...
The usefulness of ecotoxicological tools to improve the assessment of water bod...
Novais, M. H.; Penha, A. Marchã; Catarino, A.; Martins, I.; Fialho, S.; Lima, A.; Morais, M.; Palma, PatríciaThis study aimed to analyse the added value of using ecotoxicological tools to complement and improve the assessment of natural water bodies status, in situations of climate change, with a higher frequency of extreme events as floods or droughts. Four water bodies of streams in the Guadiana Basin (Álamos, Amieira, Lucefécit, Zebro) were studied in 2017 and 2018 and classified based on the Water Framework Direct...
Some Observations on Phytoplankton Community Structure, Dynamics and Their Rela...
Morais, M.; Penha, A.M.; Novais, M.H.; Landim, L.; Victória, S.S.; Barbosa, L.G.Reservoirs provide valuable services to human beings, especially in arid, semi-arid, and Mediterranean regions affected by water scarcity. The present effort aims to study the environmental descriptors of variation and the main factors influencing phytoplankton composition, structure, and diversity in five reservoirs in Santiago Island, Cape Verde, a region affected by water availability. Five campaigns took pl...
Learning from the Past: What Cultural Heritage Can Teach Us About Water Storage...
Saito, C.H; Morais, M.Due to increasing water crisis, water security is becoming more and more mainstream and associated with the Sustainable Development Goals and the human right to water. Water supply, especially for households, becomes more and more challenging. Looking to the past, several water-harvesting techniques implemented around the world since ancient times can be found and they were succeeded to deal with water scarcity...
Estrelas de Cabo Verde
Morais, M.; Malty, L.O Doutoramento em Gestão e Políticas ambientais (DGPA) é um dos mais de 20 programas de Pós-graduação da Universidade de Cabo Verde. Trata-se de um Programa Internacional, desenvolvido no quadro da Rede de Estudos Ambientais de Países de Língua Portuguesa (REALP), com a participação de 13 universidades, de cinco países de Língua Portuguesa, a saber: Cabo Verde, Portugal, Brasil, Angola e Moçambique.
Bottom-up microwave-assisted seed-mediated synthesis of gold nanoparticles onto...
Marques, A. C.; Pinheiro, T.; Morais, M.; Martins, Carla; Andrade, A. F.; Martins, R.; Sales, M. G. F.; Fortunato, ElviraThe development of accurate, reliable, inexpensive and fully recyclable analytical platforms is of utmost relevance to several fields from medical diagnosis to environmental screening. Surface-enhanced Raman spectroscopy (SERS) is a compelling detection method with high specificity and sensitivity. In this work, a microwave-assisted synthesis method was used for fast and uniform in situ growth of gold nanoparti...
Comparison of ISO 6579–1, VIDAS Easy SLM, and SureFast® Salmonella ONE Real-tim...
Furtado, R.; Coelho, A.; Morais, M.; Leitão, A.L.; Saraiva, M.; Correia, C.B.; Batista, R.In the European Union (EU), Salmonella was the causative agent responsible for almost one in three (30.7%) of all foodborne outbreaks reported by member states during 2018, causing 11,581 cases of illness, which represented an increase of 20.6% compared to 2017. Considering the importance of this foodborne zoonotic bacterium in food safety and human health, several strategies for the control and consequent dete...
Lung segmentation in CT scans of patients with lower respiratory tract infectio...
De Francesco, Sílvia; Martins, Paula; Esteves, A; Oliveira, E; Morais, M.; Oliveira, Ana; Marques, AldaThe goal of the study was to assess the effects of a respiratory physiotherapy intervention in the tracheobronchial tree (TBT) volume and lung function in patients with lower respiratory tract infection (LRTI). In this framework, a method for TBT segmentation in Computer Tomography (CT) images of patients with LRTI was implemented, allowing to obtain volumetric data and study their correlation with the lung fun...
Tau-dependent suppression of adult neurogenesis in the stressed hippocampus
Dioli, Chrysoula; Patrício, P.; Trindade, R.; Pinto, L. G.; Silva, J. M.; Morais, M.; Ferreiro, E.; Borges, S.; Mateus-Pinheiro, A.; Rodrigues, A. J.Stress, a well-known sculptor of brain plasticity, is shown to suppress hippocampal neurogenesis in the adult brain; yet, the underlying cellular mechanisms are poorly investigated. Previous studies have shown that chronic stress triggers hyperphosphorylation and accumulation of the cytoskeletal protein Tau, a process that may impair the cytoskeleton-regulating role (s) of this protein with impact on neuronal f...
Quality assessment of a battery of organic wastes and composts Using maturity, ...
Mourinha, C.; Farto, M.; Sengo, J.; Morais, M.; Cunha-Queda, C.; Palma, Patrícia; Alvarenga, PaulaChemical and biological parameters (NH4 +–N/NO3 −–N ratio, humification indices, and the activities of hydrolytic exoenzymes), commonly used to assess compost maturity and/or stability, were considered for the quality evaluation of a battery of organic materials, intended to be land applied. Acid and alkaline phosphatases, β-glucosidase, proteases and β-glucosaminidase activities proved to be reliable tests to ...
