Flexural stiffness and structural behavior of alkali-activated metakaolin faced...
Lopes, A.V.; Lopes, S.M.R.; Pinto, IsabelIn this work, the authors intend to experimentally analyze the viability of using geopolymers, in particular, by means of alkali-activated metakaolin as a binder in the construction of beams. For this, an experimental procedure will be used, where 15 reinforced beams will be tested. Of these, 10 are built using two geopolymers whose binders are made up of two different metakaolins (white metakaolin supplied by ...
Influence of Curing Temperature on the Strength of a Metakaolin-Based Geopolymer
Lopes, Adelino V.; Lopes, Sérgio; Pinto, IsabelThe present work focuses on the further development of a new family of geopolymers obtained by the alkaline activation of a binder. The aim is to find a viable alternative to concrete that can be used in civil construction. Regarding the influence of the curing temperature on this type of mixture, the recommendations in the existing literature are different for fly ash, ground granulated blast-furnace slag, and...
Structural equation modelling for predicting the relative contribution of each ...
Teixeira, José Eduardo; Bragada, José A.; Bragada, João P.; Coelho, Joana C.M.M.; Pinto, Isabel; Reis, Luís P.; Fernandes, Paula Odete; Morais, J.E.Understanding the factor weighting in the development of metabolic syndrome (MetS) may help to predict the progression for cardiovascular and metabolic diseases. Thus, the aim of this study was to develop a confirmatory model to describe and explain the direct and indirect effect of each component in MetS status change. A total of 3581 individuals diagnosed with MetS, aged 18–102 years, were selected between Ja...
Sensibility and specificity analysis for waist-to-height ratio, body mass index...
Teixeira, José Eduardo; Bragada, José A.; Bragada, João P.; Coelho, Joana C.M.M.; Pinto, Isabel; Reis, Luís P.; Saldanha, Laissa de SousaObesity is a central component of Metabolic Syndrome (MetS) and a major public health concern. A harmonizing MetS definition was developed to aggregate the different criteria used by the umbrella organizations, however there is still controversy over the most sensitive and specific parameter to characterize each MetS component. The aim of this study was to compare the sensibility and specificity for waist-tohei...
A global experiment on motivating social distancing during the COVID-19 pandemic
Legate, Nicole; Nguyen, Thuy-vy; Weinstein, Netta; Moller, Arlen; Legault, Lisa; Vally, Zahir; Tajchman, Zuzanna; Zsido, Andras N.; Zrimsek, MihaFinding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-support...
In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No ...
Dorison, Charles A; Lerner, Jennifer S; Heller, Blake H; Rothman, Alexander J; Kawachi, Ichiro I; Wang, Ke; Rees, Vaughan W; Gill, Brian P; Gibbs, NancyThe COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these st...

Predictive Factors of Progression to Carcinoma in Vocal Fold Leucoplakia
Viana Pinto, João; Ruas, José João; Andrade, António; Aragão Rodrigues, João; Pinto, Isabel; Mendes Leal, Manuel; Vales, Fernando; Pinto Moura, CarlaObjectives: To assess possible risk factors for progression in vocal fold leucoplakia. Study Design: Observational retrospective study. Material and Methods: Clinical data analysis of every patient submitted to microlaryngoscopy (MLS) with biopsy, excisional whenever possible, of vocal fold leucoplakia from January 2010 to December 2020 in the Otorhinolaryngology department of a tertiary hospital centre. Result...

Intercultural Dynamics and Strategies: The Macanese Example
Pinto, IsabelScientifically proven, interculturality is a dated concept; the beginnings of it being scientifically proven. There is, however, evidence that coexistence between different peoples has not always been peaceful. For interculturality to materialise, it is not enough for two peoples of different ethnicities to share territory, it is necessary to verify the existence of multiple historical and cultural factors. An ...
