Estimation of Annual Productivity of Sown Rainfed Grasslands Using Machine Lear...
Morais, Tiago; Jongen, M.; Tufik, C.; Rodrigues, N.; Gama, I.; Serrano, João; Domingos, T.; Teixeira, R.Grasslands play a critical role in providing diverse ecosystem services. Sown biodiverse pastures (SBP) rich in legumes are an important agricultural innovation that increases grassland productivity and reduces the need for fertilisers. This study developed a machine learning model to obtain spatially explicit estimations of the productivity of SBP, based on field sampling data from five Portuguese farms during...
Vitamin D Deficiency Does Not Impair Metabolic Improvements After Gastric Bypass
Carvalho, Ana Catarina; Guedes, Tiago; Morais, Tiago; Pereira, Sofia; Rodrigues, Egon; Nora, Mário; Guimarães, Marta; P. Monteiro, MarianaBackground: Vitamin D deficiency is a long-known cause of calcium metabolism and bone disorders. More recently, it has also been identified as a potential risk factor for obesity and diabetes. Surgical alterations of the gastrointestinal tract associated with lipid malabsorption can conceivably contribute to vitamin D deficiency. Objective: To assess the prevalence of vitamin D deficiency and secondary hyperpar...
Rainwater Piggy Banks and Green Roofs in School Buildings: Integrated Strategie...
Chen, Sanlira; Geraldes, Ana Maria; Jabur, Andrea; Vale, Patricia; Morais, Tiago; Silva, FloraThis study evaluates integrated water-saving strategies in two school centres (SC1 and SC2) located in Bragança, Portugal, combining rainwater harvesting systems (RWHS), green roofs (GR), and the replacement of conventional taps with high-efficiency models. Water consumption patterns were analysed, and nine scenarios were simulated to assess their feasibility and economic performance. Scenario 1, which focuses ...
Different Chondrus crispus Aquaculture Methods and Carrageenan Extraction
Tanoeiro, João Rui; Fortunato, Duarte; Cotas, João; Morais, Tiago; Afonso, Clélia; Pereira, LeonelWith the notable scarcity of Chondrus crispus on the Portuguese coast, and interest in exploiting compounds such as carrageenan, this study focuses on investigating different aquaculture methods and recording the yield of carrageenan from specimens grown by different methods. We compare the growth of Chondrus crispus in aquaculture using Free Floating, Cages, Attempted Fixation on Rock, and Fixed Line similar t...

A Comparative Study of the Fatty Acids and Monosaccharides of Wild and Cultivat...
García-Poza, Sara; Morais, Tiago; Leandro, Adriana; Cotas, João; Marques, João Carlos; Pereira, Leonel; Gonçalves, Ana M. M.There is a need to find new possible raw food sources with interesting nutritional values. One of the most unexploited sources are seaweeds. Thus, Ulva sp. is a green edible seaweed that shows a high growth rate in nature and can support drastic abiotic changes, such as temperature and salinity. This work aims to determine the main nutritional compounds, fatty acids (FAs) and monosaccharides profiles of Ulva sp...
Characterization of portuguese sown rainfed grasslands using remote sensing and...
Morais, Tiago; Jongen, Marjan; Tufik, Camila; Rodrigues, Nuno; Gama, Ivo; Fangueiro, David; Serrano, João; Vieira, Susana; Domingos, TiagoGrasslands are crucial ecosystems that support and provide a diverse number of ecosystem services. Sown biodiverse pastures rich in legumes (SBP) were developed with the main goal of increasing grassland production while minimizing fertilizers inputs. In this paper, the main properties of SBP in Portugal were estimated using remote sensing and machine learning in six different farms and two production years (sp...
Estimating soil organic carbon of sown biodiverse permanent pastures in Portuga...
Morais, Tiago; Tufik, Camila; Rato, A.; Rodrigues, N.; Gama, I.; Jongen, M.; Serrano, João; Fangueiro, D.; Domingos, T.; Teixeira, R.Grasslands in Portugal are key managed ecosystems, supporting and providing a diverse number of ecosystem services. Here, we developed a procedure for rapid estimation of soil organic carbon (SOC) in soil samples of sown biodiverse permanent pastures rich in legumes (SBP) in Portugal. We combined laboratory NIR spectral data analysis with artificial neural networks (ANN) to estimate the SOC content of SBP soil ...
Seaweed Potential in the Animal Feed: A Review
Morais, Tiago; Inácio, Ana; Coutinho, Tiago; Ministro, Mariana; Cotas, João; Pereira, Leonel; Bahcevandziev, KirilSeaweed (known as marine algae) has a tradition of being part of the animal feed in the coastal areas, from ancient times. Seaweeds, are mixed with animal feed, because when consumed alone can have negative impact on animals. Thus, seaweeds are very rich in useful metabolites (pigments, carotenoids, phlorotannins, polyunsaturated fatty acids, agar, alginate and carrageenan) and minerals (iodine, zinc, sodium, c...
HEPATIC CELL PROLIFERATION PEAKS ONE WEEK AFTER PORTAL VEIN LIGATION AND IS NOT...
Guimarães, Marta; Morais, Tiago; Pereira, Sofia S.; Monteiro, Ana; Vilaça, Ana; Ferreira, Tiago; Castro, Tiago; Rodrigues, Pedro; Oliveira, VeraIntroduction: Selective portal vein ligation is currently used to induce hypertrophy of healthy liver segments before partial hepatectomy performed to treat metastatic or primary liver cancer. A major limitation of this procedure is the time interval needed between the portal ligation and hepatic resection, potentially leading to tumour progression. We report the characterization of the liver regeneration kinet...
