Experimental campaign of horizontal cladding wall panels connection in industri...
Ostetto, Liana; Fonseca, Jorge; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoThe connections of cladding wall panels to precast reinforced concrete (PRC) buildings were identified as the source of several non-structural damages reported after recent earthquakes in Europe, highlighting their critical importance. The inadequate performance of these connections often leads to the collapse of cladding panels, resulting in significant economic losses and societal impacts. To better understan...
The Early and Middle Jurassic palynostratigraphy of the Lusitanian Basin (Portu...
Correia, Vânia; Pereira, Zélia; Riding, James; Duarte, Luis; Henriques, Maria Helena; Fernandes, PauloABSTRACT: Palynomorphs, especially dinoflagellate cysts, are important biostratigraphical and palaeoenvironmental tools and their study can be applied to the Lusitanian Basin of Portugal. A palynostratigraphical high-resolution survey was undertaken in eight Lower and Middle Jurassic (upper Sinemurian to lowermost Bathonian) sections from the Lusitanian Basin. We present the resulting biostratigraphical scheme ...
Change in monochromatic aberrations with accommodation in a large adult population
Mechó-García, María; Arcas-Carbonell, María; Orduna-Hospital, Elvira; Sánchez-Cano, Ana; Fernández-Sánchez, Vicente; Macedo-de-Araújo, Rute J.Background: During accommodation, the eye undergoes significant structural changes, altering wavefront aberrations. So, this study aimed to evaluate changes in Zernike coefficients up to the 6th order with different accommodation demands and ages in a large cohort of young adults, considering the decrease in pupil size with the accommodation. Methods: Aberrometric measurements for 210 healthy subjects aged 18–4...
The age and depositional environments of the lower Karoo Moatize Coalfield of M...
Fernandes, Paulo; Hancox, Philip John; Mendes, Márcia; Pereira, Zélia; Rodrigues Lopes, Gilda Maria; Marques, João; Jorge, Raul Carlos Godinho SantosThe Moatize Coalfield belongs to a network of continental Karoo basins of central Mozambique, known as the Zambezi Basin. Palynological and sedimentological studies were performed on four coal exploration boreholes to determine the age, depositional settings, and overall geological evolution of its extensive coal deposits. Clastic formations recognised in this coalfield, in ascending order, are the Vu´zi, Moati...
Detrital zircon U-Pb geochronology of the moatize and n'condédzi coalfields, za...
Fernandes, Paulo; Jorge, Raul C. G. S.; Albardeiro, Luís; Chew, David; Drakou, Foteini; Pereira, Zélia; Marques, JoãoDetrital zircon U-Pb geochronology of the Moatize and N'Condedzi coalfields in the Zambezi Karoo Basin of Mozambique provides key insights into the regional provenance, sediment dispersal pathways and basin evolution. Borehole cores from the two coalfields reveal a stratigraphy spanning the early Roadian (middle Permian) to the Carnian (Upper Triassic). The Permian sandstones of the Moatize Coalfield (MC) yield...
New insights on the upper triassic silves group in Algarve Basin, Portugal: pal...
Vilas Boas, Margarida; Pereira, Zélia; Cirilli, Simonetta; Fernandes, PauloThis paper presents the results of palynostratigraphic studies in the Silves Group in the Algarve Basin, Portugal. From bottom to top comprises the Silves Sandstones, the Silves Marl-Carbonate Evaporitic Complex, and the Volcano-Sedimentary Series. This study aims to detail the age of the Silves Group, bracketing the Triassic-Jurassic transition, using palynology. For this purpose, 250 samples were collected fr...
Palynology of the Albian–Turonian sediments from the Sumbe region, Kwanza Basin...
Rodrigues, Cristina; Mendes, Márcia; Pereira, Zélia; Nsungani, Pedro Claude; Fernandes, Paulo; Duarte, Luís Vítor; Chitangueleca, BelarminoPalynological investigations in the Sumbe region of the Kwanza Basin, Angola, have identified Albian to Turonian assemblages in four sections of the Quissonde Facies of the Mucanzo, Cabo Ledo, and Itombe formations. These studies aimed to determine their biostratigraphic ages and infer paleoenvironmental, paleoclimatic, and paleogeographic models. The presence of Odontochitina costata, Palaeohystrichophora infu...
Bilateral Renal Artery Thrombosis: A Rare Case of Severe Kidney Failure with Pa...
Costa, Cláudia; Oliveira, João; Branco, Carolina; Fernandes, Paulo; Lopes, José António; Agapito Fonseca, JoséRenal artery thrombosis is a rare and overlooked cause of kidney failure. Clinical presentation is unspecific, leading to delays in diagnosis and, therefore, preventing timely treatment. Herein, we present a case of bilateral renal artery thrombosis that led to severe acute kidney injury assumed to be irreversible. A 61‐year‐old Caucasian female presented to the emergency department with nausea, vomiting and re...
Influence of retrofitting in the seismic behaviour of precast reinforced concre...
Ostetto, Liana; Batalha, Nádia; Sousa, Romain; Fernandes, Paulo; Rodrigues, HugoPrevious destructive earthquakes caused large economic losses as well as human losses. Seismic risk studies are of paramount importance to predict the impact of future earthquakes and support seismic risk mitigation policies. The present study presents a seismic risk assessment based on the cost and direct loss assessment of precast industrial buildings with different retrofitting levels in terms of horizontal ...

Lopes, Andreia; Fernandes, Paulo; Brazão, Roberto; Dias, M. GraçaO consumo excessivo de açúcar está relacionado com o desenvolvimento de doenças crónicas, nomeadamente a obesidade e a diabetes tipo 2, con forme o evidenciam diversos estudos científicos. Para reduzir a prevalência deste tipo de doenças, o Governo português aprovou a Estratégia Integrada para a Promoção da Alimentação Saudável (EIPAS) que, entre outros objeti vos, pretende uma redução progressiva do consumo di...
