Comparative evaluation of photocatalytic efficiency measurement techniques thro...
Costa, Manuel F. M.; Carneiro, Joaquim A. O.; Lessa, Fabíula Pereira; Lima Jr., Orlando; Margalho, Élida Melo; Zahabizadeh, BehzadSelf-cleaning cementitious materials, particularly with TiO2-based photocatalytic coatings, offer significant benefits by reducing surface deterioration and maintenance requirements, even in harsh urban environments. Despite the growing interest in self-cleaning cementitious materials, an international standard test method to calculate their efficiency has not yet been established for this specific type of subs...
A PESC: o Enquadramento Político
Pereira, EduardoDois desafios foram colocados à Conferência Intergovernamental: - Fazer que o cidadão da União sinta a Europa como sua. Não foram criadas as condições políticas para que o cidadão olhasse a Europa com outros olhos; - Conseguir ter êxito no alargamento. Não foram reunidas as condições políticas necessárias. A Comissão expressou a vontade de que a PESC fosse encarada numa perspectiva de longo prazo. Lamenta-se o ...
On risk analysis of the use of Cannabinoids compounds as therapy in Dementia
Pereira, Eduardo; Fernandes, Rúben; Luís, Carla; Baylina, Pilar; BAYLINA MACHADO, PILARNowadays dementia pharmaceutical treatment has an unfavourable risk-benefit relation. New therapeutic approaches’ adoption is need due to the high prevalence of this condition. To evaluate the risk of using cannabinoids compounds as nonharmful therapeutic approach in dementia. A systematic literature review based on PRISMA was performed. PubMed and Clinical Trials database were used to collect articles between ...
A Demonstrator for future fiber-optic active SMART repeaters
Cruz, Nuno A.; Silva, António; Zabel, Friedrich; Ferreira, Bruno; Jesus, Sergio; Martins, Marcos S.; Pereira, Eduardo; Matos, Tiago; Viegas, RubenThe deep-sea environment still presents many challenges for systematic, comprehensive data acquisition. The current generation of SMART cables incorporates low-power sensors in long-range telecommunication cables to improve knowledge of ocean variables, aid in earthquake and tsunami warnings, and enhance coastal protection. The K2D Project seeks to expand SMART cables' capabilities by increasing the diversity o...
Mining waste as an eco-friendly adsorbent in the removal of industrial basazol ...
Hawerroth, Mariane; Pereira, Eduardo; Almeida, Lariana N.B. de; Martins, Ramiro; Pietrobelli, Juliana Martins TeixeiraThe circular economy seeks to better use materials and minimize waste generation. This article evaluated the use of granite rock powder, a mining residue, as an adsorbent for the Basazol Yellow 5G (BY5G) dye and the reuse of the residue generated by the by treating this effluent in construction products. Characterization of the adsorbent material by N2 physisorption indicated a surface area of 1514 m2 g−1. Ener...
Preliminary analysis of the mechanisms, characteristics, and causes of a recent...
Tomás, Roberto; Pinheiro, Marisa; Pinto, Pedro; Pereira, Eduardo; Miranda, Tiago F. S.A catastrophic rock planar slide occurred in the parish of Palmeira de Faro, Esposende (N Portugal), on November 23, 2022, in the middle of the night, killing two people while they were asleep in the first floor of a building close to the affected cut slope. The collapsed slope presented a maximum height of about 23 m, and was excavated in a granitic rock mass strongly weathered, in some areas by mechanical mea...
Interactive Dichotomous Key for identifying rocks: a proposal to use with high ...
Batista, Adriana; Dias, Rui; Silva, Vânia; Pereira, Eduardo; Gomes, Adelina; Paiva, André; Soares, Alexis; Nascimento, Francisco; Leal Machado, IsabelThe Estremoz Science Center has as main objective the dissemination and scientific literacy of population, with special emphasis on Earth Sciences. Recently, it has developed an unprecedented tool for identifying rocks: a dichotomous key called “What rock is this?” This key is the result of an extensive reflection and conceptualization that had as main goal the application of the concept of dichotomous key to E...
Numerical analysis of the flow field and cross section design implications in a...
Maslov, Dmytro; Pereira, Eduardo; Duarte, Duarte; Miranda, Tiago; Ferreira, Vasco; Tieppo, Marcos; Cruz, Fábio; Johnson, JessicaNowadays, multifunctional artificial reefs are integrated in coastal areas all around the world. The design of such structures is currently complex and subjective. In this context, it is essential to improve overall design approaches to more effectively relate artificial reef geometry, function and optimal performance to specific deployment sites. Part of the solution to this challenge may lie in the use of in ...

Early-age shrinkage and bond of LC-TRM strengthening in rammed earth
Eudave, Rafael Ramirez; Silva, Rui André Martins; Pereira, Eduardo; Romanazzi, AntonioThe wide dissemination of earth-based structures as contemporary, vernacular or heritage constructions in re-gions with important seismic hazard demands the design of solutions that improve the typical low structural performance resulting from intrinsic material limitations. Only in this way, it is possible to promote a comprehensive seismic protection of this heritage and of the life of their inhabitants. One ...
