Towards Cerebrospinal Fluid-Free Ultrasensitive Alzheimer's Diagnostics using M...
Norman, B.; Arjum, A. M.; Vulpe, G.; Liu, Guoyi; Deshpande, S.; Moreira, F.Neurofibrillary tangles (NFTs), vital in Alzheimer's disease (AD) diagnosis, consist of Tau-441, a Tau protein with 441 residues. Originating in the entorhinal cortex, these tangles spread as AD progresses. Combining the identification of tau proteins in plasma by Zetterberg and co-workers and the shared ectodermal origin of the brain and skin, suggests the presence of AD biomarkers in ISF and blood. This study...
Anthropogenic food subsidies reshape the migratory behaviour of a long-distance...
Marcelino, J.; Franco, A.M.A.; Acácio, M.; Soriano-Redondo, A.; Moreira, F.; Catry, I.Bird migratory journeys are often long and hostile, requiring high energetic expenditure, and thus forcing birds to pause between migratory flights. Stopover sites allow migrants to replenish fuel reserves and rest, being crucial for the success of migration. Worldwide, the increasing accumulation of waste on landfills and rubbish dumps has been described to provide superabundant food resources for many bird sp...
Alterações morfopatológicas no rim de rato com obesidade e insulino-resistência
Teixeira, C.; Guedes, C.; Sousa, A.; Lopes, S.; Luís, C.; Soares, R.; Baylina, Pilar; Moreira, F.; Alencastre, I.; Fernandes, RúbenA diabetes é uma das patologias com elevada taxa de comorbilidades associadas, como a nefropatia diabética que por sua vez leva a doença renal de estadio terminal (DRET). Estudos prévios demonstraram que indivíduos que desenvolveram DRET apresentavam um IMC mais elevado revelando a importância da obesidade no desenvolvimento da doença. Existe uma relação entre a atividade endócrina do tecido adiposo e a doença ...
Risk of bird electrocution in power lines: a framework for prioritizing species...
Biasotto, L. D.; Moreira, F.; Bencke, G. A.; D’Amico, M.; Kindel, A.; Ascensão, FernandoElectrocution on power lines is an important human-related cause of bird mortality and an important conservation issue worldwide. Besides impacts on bird populations, electrocutions cause power outages, resulting in damage to power line network integrity. However, there is a general lack of knowledge on the risk of bird electrocution, especially in developing countries. Generating information over large scales ...
Effective non-invasive runway monitoring system development using dual sensor d...
Sharma, R.; Moreira, F.; Saragoça, G.; Ferreira, J.At airports the runways are always troubled by the presence of ice, water, cracks, foreign objects, etc. To avoid such problems the runway is supposed to be monitored regularly. To monitor a large number of technique are available such a runway inspection mobile vans. These techniques are largely human dependent and need interruptions in the runway’s operations for inspection. In this position paper, we suggest...
Extreme events are more likely to affect the breeding success of lesser kestrel...
Marcelino, J.; Silva, J. P.; Gameiro, J.; Silva, A.; Rego, F. C.; Moreira, F.; Catry, I.Climate change is predicted to severely impact interactions between prey, predators and habitats. In Southern Europe, within the Mediterranean climate, herbaceous vegetation achieves its maximum growth in middle spring followed by a three-month dry summer, limiting prey availability for insectivorous birds. Lesser kestrels (Falco naumanni) breed in a time-window that matches the nestling-rearing period with the...
Identifying and explaining the farming system composition of agricultural lands...
Silva, J.F.; Santos, J.L.; Ribeiro, P.F.; Canadas, M.J.; Novais, A.; Lomba, A.; Magalhães, M.R.; Moreira, F.In mountain landscapes, agricultural abandonment is taking place in the most vulnerable areas, while intensification increases in the most productive lands. These contrasting processes, which have different impacts on biodiversity and ecosystem services (BES), are related to changes in the farming system component of these landscapes. Farming systems are identified based on farmer’s decisions on, for example, t...
Task-based automatic evaluation of people with intellectual disabilities perfor...
Gomes, Pedro R.; Torrinha, A.; Costa, A. N.; Moreira, F.; Dantas, O.; Oliveira, R.; Santos, F.; Lemos, A. F.; Costa, J. M.; Lima, C. S.This paper is concerned with the automatic evaluation of selected tasks performed by people with intellectual Disabilities. According to the International Classification of Functioning, Disability and Health (ICF) system, subjects must be divided into two groups: group with no difficulty (N) and group with difficulty (D) being this classification based on performances obtained in a conventional table (CT) socce...
Intensification of heterogeneous photocatalysis by applying a kenics® static mi...
Vilar, Vítor J.P.; Diez, A.M.; Moreira, F.; Marinho, B.; Espínola, J.; Martins, Ramiro; Sanromán, M.; Pazos, M.; Boaventura, RuiDespite scientific community’s efforts, overcoming mass and photon transfer limitations remain a main challenge for heterogeneous photocatalysis with immobilized catalysts. Here, a Kenics® static mixer was used for the first time as catalyst support for heterogeneous photocatalysis in tubular reactors. This permitted not only to take advantage of the enhanced mass transfer supplied by the intense mixing, but al...
Assessing the extent and the environmental drivers of Eucalyptus globulus wildl...
Catry, F. X.; Moreira, F.; Deus, E.; Silva, J. S.; Águas, AnaTasmanian blue gum (Eucalyptus globulus) has been increasingly used in forestry outside its native range, and is nowadays one of the most important pulpwood species in the world. E. globulus has great economic importance in many countries, and in Portugal it has recently become the most widespread tree species. However, there is also an increasing concern about the potential ability of eucalypts to naturally es...
