Santos, António; Martins, José; Pestana, Pedro Duarte; Gonçalves, Ramiro; São Mamede, Henrique; Branco, FredericoThis systematic literature review investigates the factors influencing cloud computing adoption within both educational and organizational settings. By synthesizing a comprehensive body of research, this study finds and analyzes the determinants that shape the decision-making process about cloud technology adoption. Security, cost-effectiveness, scalability, interoperability, and regulatory compliance are exami...

Santos, AntónioO presente relatório enquadra-se no âmbito da Unidade Curricular de Estágio integrada na licenciatura em Comunicação Multimédia, curso referente à Escola Superior de Educação, Comunicação e Desporto, no Instituto Politécnico da Guarda. Esta etapa reflete uma parte substancial da aplicação dos conhecimentos teórico-práticos adquiridos ao longo do percurso formativo, numa perspetiva interdisciplinar, através do e...
Investigating contamination indexes and mobility processes in mine-stream sedim...
antunes, Isabel Margarida; Carvalho, Paula; Albuquerque, Maria Teresa; Santos, AntónioThe mining industry plays a crucial role in today’s society due to the growing demand for strategic materials. Nevertheless, it is essential to acknowledge the signi cant threats posed to the environment by mining operations. Striking a delicate balance between resource needs and environmental protection is imperative.

Guidelines for the Diagnosis and Treatment of Uncomplicated (Non-Lymphogranulom...
Andrade, Pedro; Azevedo, Jacinta; Lisboa, Carmen; Fernandes, Cândida; Borrego, Maria José; Borges-Costa, João; Reis, Joel; Santiago, FelicidadeChlamydia trachomatis infection is the most prevalent sexually transmitted bacterial infection in the world. Being associated with a large number of asymptomatic carriers, the diagnosis is frequently challenging and requires appropriate laboratory testing. In Portugal, the incidence of the disease has been consistently increasing in recent years, meaning that special awareness is required for case identificatio...
The geochemical behavior of Pb and Zn in waters and stream sediments around a f...
Carvalho, Paula; Antunes, I.M.H.R.; Albuquerque, Maria Teresa; Santos, AntónioIn Portugal, ore mineral exploitation has left millions of tons of mining waste rich in metals in the environment. The former Várzea Pb-Zn mine is located in the Várzea dos Cavaleiros village, about 10 km from Sertã village and 65 km from Castelo Branco county, central Portugal. The Pb-Zn quartz vein with N10ºW; 75º SW orientation, 0.5-1.5 m thick, intruded the Neoproterozoic-Cambrian schist-greywacke complex. ...
Geo-accumulation indexes of trace elements in sediments from uranium environmen...
Antunes, Isabel Margarida Horta Ribeiro; Teixeira, Rui; Valente, Teresa Maria Fernandes; Santos, AntónioStream sediments are usually used as a tool for contamination evaluation. The studied area is an abandoned uranium mine located in Central Portugal, in a not steep area, with altitudes ranging from 360 to 380 m. Geoaccumulation index and contamination factor have been used in the as-sessment of the degree of contamination of stream sediments with toxic metals. The stream sediments are heavily to extremely conta...
Stream sediments as a repository of U, Th and As around abandoned uranium mines...
Carvalho, Paula; Antunes, I.M.H.R.; Albuquerque, M.T.D.; Santos, António; Cunha, Pedro ProençaThis work focuses on the study of water–sediment interaction around abandoned uranium mines with open-pit lakes and mine dumps. Nineteen water and eleven stream sediment samples were collected in the abandoned Barrôco D. Frango mine, central Portugal. The trace element distribution was compared with other abandoned uranium mines in Portugal and worldwide. Generally, U, Th, and As contents in the open-pit water ...
Water-rock interaction and potential contamination risk in a U-enriched area
Antunes, Isabel Margarida Horta Ribeiro; Teixeira, Rui; Albuquerque, Teresa; Valente, Teresa Maria Fernandes; Carvalho, Paula; Santos, AntónioThe Picoto mining area is in the village of Vilar Seco (Viseu), central Portugal. Mineralization occurs mainly in quartz veins with meta-torbernite and uranophane and some U-bearing minerals, cutting a Variscan granite. Exploitation took place in two phases, between 1917 and 1953, and since the closure, the area has never been remediated. Water–rock interaction processes, including the mobility of potentially t...
