Protest cycles and democracy in Portugal, 2000–2019
Fernandes, T.; Araújo, C.Since the global protest wave of the 1960s-1970s, the sphere of collective action became a common subsystem of modern democratic regimes, alongside conventional representative institutions, such as elections, parliaments or bodies of state-interest group consultation (e.g., pluralist or corporatist) (Dolenec, 2017; Dolenec at al. 2020; Ekiert and Kubik, 2001; Schmitter, 1981; Schmitter 1999). Democratic regimes...
Species richness of Myxobolus (Cnidaria, Myxozoa) parasites infecting thicklip ...
Guimarães, J.; Casal, G.; Alves, A.; Araújo, C.; Rocha, S.Background: Myxozoans are widespread cnidarian parasites that mostly infect fish and annelids as temporary and definitive hosts, respectively [1]. Mullets are a diverse fish group, which ubiquitous nature leaves vulnerable to parasitic infections [2]. Objective: This study aimed to acknowledge the myxozoan diversity infecting thicklip grey mullet Chelon labrosus in the Douro River estuary in northern Portugal. ...
Description of sphaeractinomyxon types (Cnidaria: Myxosporea) from marine oligo...
Araújo, C.; Rangel, L. F.; Casal, G.; Costa Araújo, D.; Rocha, S.Background: Myxosporeans are important fish endoparasites with a complex life cycle that involves the production of actinospores in annelid hosts. More than 2,400 myxosporean species are presently known, yet only about 60 have their complete life cycle described [1]. Difficulties in the annelid sampling and examination, namely from the marine environment, and typically low prevalence of infection, hinder our kn...
Anti-reflective and superamphiphilic coatings on polycarbonate
Valentim, P. T.; Retolaza, A.; Llobet, J.; Araújo, C.; Cruz, Sílvia Manuela Ferreira; Machado, C.; Pontes, A. J.; Santos, H.; Sousa, P. C.In this work, we investigated the transmission enhancement of a polycarbonate substrate (PC) at the beginning of the near-infrared part of the electromagnetic spectrum, by incorporating anti-reflective coatings (ARC) on the surface. Thin film ARC formed by combining layers of SiO2, TiO2, and SiNx were studied, and the influence of the layers thickness on the optical response of the systems was explored, with th...
Artificial intelligence in digital customer journey
Araújo, C.; Gonçalves, R.; Lopes da Costa, R.; Dias, Á.; Pereira, L.Artificial intelligence (AI) is present in many business areas, the marketing of the fashion industry being one of them. In this sense, AI becomes relevant for firms, helping to acquire better consumer data and to stand out from the competition by offering personalised, rich, and unique experiences. This study seeks to understand the current state of interaction that consumers have with AI during the digital cu...
Protest cycles and democracy: a comparison between Portugal and Spain, 2000-2019
Fernandes, T.; Araújo, C.; Santos, I. G.; Romanos, E.This article analyses and compares the protest cycles of Portugal and Spain in the first two decades of the 21st century. Considering that the possibility of exercising the right to dissent in the public sphere constitutes one of the key characteristic elements of democracy, but is also a factor of its consolidation, this analysis contributes to the understanding of protest as a legitimate form of political par...
Prevalence of Cardiovascular Risk Factors in the Elderly Population of Alentejo...
Marques, Maria do Céu Mendes; Vaz, A.; Leite, A.F.; Araújo, C.; Condeço, C.R.; Ribeiro de Deus, J.The objective of this chapter is to identify cardiovascular risk factors in the elderly and their prevalence in the elderly population of Alentejo. The research question was elaborated according to the PI[C]OD methodology. The prevalence studies included allow the authors to identify the risk factors with the greatest impact on cardiovascular diseases, with the analysis of at least one of the factors (hypertens...
Micro-simulation of the impact of different speeds on safety road travel and ur...
Ribeiro, Paulo; Araújo, C.; Gonçalves, L. A. P. J.; Dias, G. J. C.; Cunto, F.In recent days, the use of micro-simulation as an additional tool for the study of the network makes this management faster and more efficient, avoiding in situ studies. However, although it is a useful tool, it is necessary that the model under study is the best represented possible in order to obtain results that best fit the reality of the road, and a poor calibration of the model can provide results that do...
Palynology of Bonito and Barro Branco coal seams from Rio Bonito Formation (Low...
Pereira, Zélia; Mendes, Márcia; Souza, P.A.; Rodrigues, C.; Fernandes, Paulo; Ade, M.; Araújo, C.; Almeida, J.R.L.; Santos, E.M.; Rocha, H.V.ABSTRACT: Seven coal seams were sampled from several mines and outcrops of the Rio Bonito Formation, Bonito and Barro Branco coal seams, in the coal mining region of Criciúma, Paraná Basin, Santa Catarina State (Brazil), for a detailed palynostratigraphic study. The coal seams sampled yield abundant, diverse and moderately to well preserved palynological assemblages. A total of twenty-seven spore species, fourt...
Identification of OAF and PVRL1 as candidate genes for an ocular anomaly charac...
David, Dezso; Anand, D.; Araújo, C.; Gloss, B.; Fino, J.; Dinger, M.; Lindahl, P.; Pöyhönen, M.; Hannele, L.; Lavinha, J.Keratolenticular dysgenesis (KLD) and ectopia lentis are congenital eye defects. The aim of this study is the identification of molecular genetic alterations responsible for those ocular anomalies with neurologic impairment in an individual with a de novo balanced chromosome translocation t(11;18)(q23.3;q11.2)dn. Disruption of OAF, the human orthologue of the Drosophila oaf, by the 11q23.3 breakpoint results in...
