On the Evolution of the Stock Market Efficiency: Evidence From Emerging Markets
Lobão, Júlio; Pacheco, Luís Miguel; Cruz, NunoThe study of market efficiency is one of the most covered topics in the field of financial markets, with the Efficient Market Hypothesis gathering devotees as well as several critics. The perception of markets as agents with an adaptive nature gave rise to the Adaptive Market Hypothesis (AMH). This paper aims to combine this evolutionary view of market efficiency with the need to assess the behavior of emerging...
Persistent Proinflammatory Cytokine Profile in the Tear Fluid of Stable Keratoc...
Gil, Pedro; Quadrado Gil, João; Cruz, Nuno; Costa, Celso; Rodrigues-Santos, Paulo; Sousa, Luana Madalena; Almeida, Jani Sofia; Fernandes, RosaPurpose: Keratoconus is traditionally classified as a noninflammatory corneal ectasia, despite growing evidence suggesting an underlying inflammatory component. This study evaluates whether patients with stable keratoconus exhibit persistent inflammatory activity in tear fluid compared to healthy controls. Methods: Cross-sectional case-control study. Keratoconus progression was evaluated using tomographic and c...

Biomass ash-based soil improvers: impact of formulation and stabilization condi...
Cruz, Nuno; Avellan, A.; Ruivo, L.; Silva, F. C.; Rӧmkens, P.F.A.M.; Tarelho, L.A.C.; Rodrigues, S. M.Biomass ash and sludge from pulp and paper industry have enormous potential to be recycled and used as components in soil improvers. Those materials can supply large amounts of nutrients and organic matter and its recycling avoids the need of landfilling. However, these wastes cannot be directly applied to soils. Some form of processing is required to ensure efficient soil pH correction, fertilization, guarante...
Relevant Aspects of Piranha Passivation in Ti6Al4V Alloy Dental Meshes
Cruz, Nuno; Gil, Javier; Punset, Miquel; Manero, José María; Tondela, João Paulo; Verdeguer, Pablo; Aparicio, Conrado; Rúperez, ElisaPassivation of titanium alloy dental meshes cleans their surface and forms a thin layer of protective oxide (TiO2) on the surface of the material to improve resistance to corrosion and prevent release of ions to the physiological environment. The most common chemical agent for the passivation process of titanium meshes is hydrochloric acid (HCl). In this work, we introduce the use of Piranha solution (H2SO4 and...
