Insights about the Sines massif: a reinterpretation of geophysical data to the ...
Marques, Fábio; Pedro, J.; Araujo, A.; Moita, Patrícia; Carneiro, Júlio; Sousa, Pedro; Carvalho, João; Correia, AntonioABSTRACT: The InCarbon project aims to evaluate the potential for storage of captured CO2 using in-situ mineral carbonation in mafic and ultramafic plutonic rocks in Alentejo, Portugal. The Sines massif appears to be the most promising massif for mineral carbonation and its geochemistry, petrography, mineralogy, volume and extension are characterized. Its offshore volume and extension are evaluated through rein...
Geoquímica de sedimentos lacustres em sistemas com elevadas taxas de sedimentaç...
Fonseca Araújo, Joana; Nogueira, Pedro; Fonseca, Rita; Pinho, C.; Araujo, A.Resumo: As condições climáticas da República Dominicana são propícias à ocorrência de elevadas taxas de erosão e, consequentemente, a elevadas taxas de sedimentação, prejudicando por isso o potencial de armazenamento de água e de produção de energia eléctrica das barragens. Neste estudo, foram abordadas duas barragens, Tavera e Sabana Yegua, nas quais se amostraram os solos das respectivas bacias de drenagem, b...
Hierarchical HRP-crosslinked silk fibroin/ZnSr-doped TCP nancocomposites toward...
Ribeiro, V. P.; Pina, S.; Canadas, R. F.; Gheduzzi, S.; Araujo, A.; da Silva Morais, Alain; Vilela, C.; Vieira, S.; Cengiz, I. F.; Reis, R. L.[Excerpt] Introduction. Recent investigations highlight promising regenerative strategies for osteochondral (OC) tissue treatment, such as hierarchical nanocomposite scaffolds containing ionic dopants.1,2 They allow cell infiltration and ECM formation throughout the engineered cartilage and subchondral tissues. The biomechanical behavior, antibacterial properties, and in vivo performance of hierarchical nanostr...

Araujo, A.; Caldeira, Bento; Martins, Antonio; Borges, José Fernando; Moreira, Noel; Fonseca Araújo, Joana; Maia, Miguel; Vicente, S.; Afonso, P.RESUMO: Na segunda quinzena de janeiro de 2018 realizou-se um estudo da macrossismicidade associada ao sismo de Arraiolos de dia 15 de janeiro. No presente trabalho descreve-se a metodologia usada na recolha de informação, o tratamento dos dados e a sua representação na forma de mapa de intensidades. A distribuição geográfica das intensidades mostra um alongamento da isossista de intensidade IV na direção N-S e...

Bioelectrical impedance analysis of body composition for the anesthetic inducti...
Araujo, A.; Machado, H.; Falcão, A.; Soares-da-Silva, P.BACKGROUND: Older people are currently the fastest growing segment of the worldwide population. The present study aimed to estimate propofol dose in older patients based on size descriptors measured by bioelectrical impedance analysis (BIA). METHODS: A cross sectional study in adult and older patients with body mass index equal to or lower than 35 kg/m2 was carried out. BIA and Clinical Frail Scale scoring were...
Analysis of body differences for the design of children's clothing
Bezerra, G.; Carvalho, Miguel; Araujo, A.; Rocha, M.; Barboza, R.This paper discusses anthropometric data obtained through 3D body scanner technology, aiming the dimensioning of Portuguese children's measurements for the design of clothing. The study comprises boys and girls from the Northern Region of Portugal aged between two and ten years old. The main objective of this part of the study was to evaluate the possibility of grouping children with six and seven years old in ...
Y zeolite-supported niobium pentoxide catalysts for the glycerol acetalization ...
Ferreira, C.; Araujo, A.; Calvino-Casilda, V.; Cutrufello, M. G.; Rombi, E.; Fonseca, António; Bañares, M. A.; Neves, Isabel C.Faujasite zeolite-supported niobium-based catalysts (with Nb2O5 amounts of 5 and 15wt%) were prepared by impregnation of NaY, HY, and HUSY zeolites using a niobum(V) ammonium oxalate complex. These obtained Nb-containing catalysts were calcined and thoroughly characterized by different physico-chemical techniques. The characterization results revealed that niobium oxide was successfully loaded on the surface of...
Enhanced UV flexible photodetectors and photocatalysts based on TiO2 nanoplatforms
Nunes, D.; Pimentel, A.; Araujo, A.; Calmeiro, T. R.; Panigrahi, S.; Pinto, J. V.; Barquinha, P.; Gama, F. M.; Fortunato, E.; Martins, R.Abstract: In this study, titanium dioxide (TiO2) nanostructured films were synthesized under microwave irradiation through low temperature synthesis (80 °C) and integrated in ultraviolet (UV) photodetectors and as photocatalysts. Bacterial nanocellulose (BNC), tracing paper, and polyester film were tested as substrates, since they are inexpensive, flexible, recyclable, lightweight, and when associated to low te...
