Hydrometeorological dataset (2018–2023) from the largest Portuguese reservoir: ...
Rodrigues, Gonçalo; Purificação, Carolina; Potes, Miguel; Costa, Maria João; Salgado, RuiThe databases provided for two meteorological stations installed in the Alqueva reservoir (the largest artificial lake in Europe), one located on a floating platform and the other on the shore (approximately 1 km away in a straight line), cover a period of 6 years, from 2018 to 2023. The data available are, the hourly accumulated precipitation as well as the hourly averages of surface water temperature (0.25 m ...
Moisture Content Vegetation Seasonal Variability Based on a Multiscale Remote S...
Santos, Filippe; Rodrigues, Gonçalo; Potes, Miguel; Couto, Flavio; Costa, Maria João; Dias, Susana; Monteiro, Maria José; Ribeiro, Nuno; Salgado, RuiWater content is one of the most critical characteristics in plant physiological development. Therefore, this information is a crucial factor in determining the water stress conditions of vegetation, which is essential for assessing the wildfire risk and land management decision-making. Remote sensing can be vital for obtaining information over large, limited access areas with global coverage. This is important...
Assessment of Water Surface Reflectance and Optical Water Types Over Two Decade...
Rodrigues, Gonçalo; Potes, Miguel; Costa, Maria JoãoThis study focuses on comparing surface reflectances and optical water types (OWTs) obtained in Alqueva reservoir, located in the Alentejo region (Portugal), over a period of two decades (2003–2022) using four datasets: the moderate resolution imaging spectroradiometer (MODIS), themedium-resolution imaging spectrometer, the ocean and land color instrument aboard Sentinel-3, and the multispectral instrument aboa...
Fenestrated Physician-Modified Endografts (PMEGs) - a Viable Option for Urgent ...
Bento, Rita; Alves, Gonçalo; Rodrigues, Gonçalo; Garcia, Rita; Ribeiro, Tiago; Cardoso, Joana; Soares Ferreira, Rita; Ferreira, Maria EmiliaINTRODUCTION: Fenestrated and branched stent graft technology has come a long way over the past few years, enabling the treatment of complex juxtarenal aneurysms, thoracoabdominal aneurysms, and arch pathologies. Many innovations have been developed, namely device and delivery optimization and technical tricks. These concepts have proven to work well when there is sufficient time to plan and manufacture a custo...
Optical study of soil samples contaminated by heavy metals from the São Domingo...
Oliveira, Rui Jorge; Teixeira, Pedro; Caldeira, Bento; Borges, José Fernando; Costa, Maria João; Bortoli, Daniele; Potes, Miguel; Rodrigues, GonçaloThe study of soils contaminated by heavy metals (HMs) is a hard task that implies the collecting of soil samples in an area representative of the contaminated space. For example, for water samples, the law requires the creation of a study grid with 5 ha spacing. Considering this spacing requirement, to the soil from the São Domingos Mine, that have an area of approximately 2000 ha, we need to collect 400 sample...
Relatório Final do projeto ALOP (ALT20-03-0145-FEDER-000004)
Salgado, Rui; Palma, Patrícia; Morais, M. Manuela; Almeida, Adelaide; Alvarenga, Paula; Antunes, Célia; Aranha, Sergio; Bárias, Samuel; Barrenho, JoelO Projeto ALOP teve início formal a 25 de Maio de 2016 e terminou a 31 de dezembro de 2019. Neste relatório final procuramos dar conta das atividades efetuadas e principalmente dos resultados obtidos. A tarefa está facilitada pois o projeto, em conjunto com as sinergias geradas com outros projetos e as colaborações nacionais e internacionais dos vários membros da equipa permitiram a publicação de um invejável n...

Leriche syndrome after visceral aortic revascularization – what now?
Bento, Rita; Alves, Gonçalo; Bastos Gonçalves, Frederico; Rodrigues, Gonçalo; Ferreira, Rita; Ferreira, Maria EmíliaINTRODUCTION: Thoraco-bifemoral bypass (TBF) is an alternative to aorto-bifemoral bypass (ABF) or axilobifemoral bypass for severe aortoiliac occlusive disease. TBF may be particularly useful in select patients with concurrent visceral aortic branch vessel disease, infrarenal aortic occlusions, or after failed ABF. We describe a clinical case of a symptomatic Leriche syndrome in the presence of concurrent visce...
Mapping the Mine: Combining Portable X-ray Fluorescence, Spectroradiometry, UAV...
Nogueira, Pedro; Silva, Marcelo; Roseiro, José; Potes, Miguel; Rodrigues, GonçaloOld and abandoned mines are testimonials of ancient industrial activities, and as such, they are able to convey environmental concerns. A multidisciplinary approach combining ground measurements—i.e., portable X-ray fluorescence and optical spectroradiometry—with airborne multispectral images—i.e., Sentinel-2 and unmanned aerial vehicles—was conducted to define a baseline for the characterization of areas that ...
Eficiência do uso da água na cultura do milho em 4 sistemas de rega
Oliveira, Margarida; Amaral, Artur; Cascareja, Diogo; Rodrigues, GonçaloA água é um bem cada vez mais escasso, em que a sua utilização requer uma monitorização precisa e eficaz de modo a evitar o seu desperdício. O projeto Pegada 4.0, entre outros objetivos, pretende avaliar a pegada hídrica de várias culturas, nomeadamente na cultura do milho, uma cultura com elevada expressão produtiva na região do Ribatejo, mas também com elevados consumos de água. O presente estudo visa a avali...
