- Addressing the complex links between psychopathy and childhood maltreatment, emotion regulation, and aggression-a network analysis in adultsPublication . Moreira, Diana; Silva, Candy; Moreira, Patrícia; Pinto, Tiago Miguel; Costa, Raquel; Lamela, Diogo; Jongenelen, Inês; Pasion, RitaChildhood maltreatment is the strongest predictor of psychopathology and personality disorders across the lifespan and is strongly associated with a variety of psychological problems, namely, mood and anxiety disorders, behavioral and personality disorders, substance abuse, aggression, and self-harm. In this study, we aim to provide a comprehensive picture of the interplay between different traits of psychopathy and distinct dimensions of childhood maltreatment, emotion regulation, and aggression. Using a cross-sectional design, we employed correlational network analysis to explore the nomological network of psychopathy and provide a sample-based estimate of the population parameters reflecting the direction, strength, and patterns of relationships between variables. The sample consisted of 846 adults (71% females) who completed questionnaires measuring psychopathy, childhood maltreatment, emotion regulation, and aggression. The results highlight that disinhibition traits of psychopathy are the closest attributes of early experiences of abuse (but not neglect) in childhood and correlate with all dimensions of emotion regulation difficulties, being specifically associated with reactive aggression. Neglect was a unique attribute in the nomological network of meanness, with widespread correlations with emotion regulation difficulties but also an increased ability to engage in goal-directed behavior. Physical abuse was the only dimension of childhood adversity that was found to be intercorrelated with boldness and increased emotional regulation was found in this psychopathic trait. No significant associations were found between boldness, meanness, and aggression once shared variance with disinhibition was controlled. These results are discussed in terms of their implication for research and clinical practice.

- Available green conservation methodologies for the cleaning of cultural heritage: an overviewPublication . Gueidão, Marta; Vieira, Eduarda; Bordalo, Rui; Moreira, PatríciaThe introduction of new guidelines and regulations on chemical production, use, treatment or disposal demanded the development of greener alternatives to conventional products and methodologies. This review briefly presents some of the most promising innovative systems applied in the cleaning of cultural heritage – lasers, green solvents, microemulsions or micellar solutions, bacterial cells or enzymes, ionic liquids and gels. Their advantages and drawbacks are discussed, along with further improvements.
- Bioaugmentation of aerobic granular sludge with dye-decolorizing yeast for textile industrial wastewaterPublication . Mendes, Marta; Moreira, Irina S.; Moreira, Patrícia; Pintado, Manuela; Castro, Paula M. L.A sequencing batch reactor (SBR) inoculated with activated sludge and bioaugmented with a dye-decolorizing yeast strain—Yarrowia lipolytica (HOMOGST27AB) was assembled to form yeastbioaugmented aerobic granular sludge (AGS). The bioaugmented AGS-SBR was operated for the treatment of synthetic saline wastewater (12 g L1) intermittently fed with a reactive textile dye (Navy Everzol ED) at 25, 15, and 7.5 mg L1. Dye degradation did not occur, although some dye adsorbed to the granules. AGS-SBR performance in removing carbon and nitrogen was good and was not affected by the dye addition. Bioaugmentation with the yeast Y. lipolytica (HOMOGST27AB) occurred with success, proved by sequencing samples from granules throughout the reactor operation. The AGScore microbiome gathered essentially microorganisms from the Proteobacteria and Bacteroidetes phyla.The microbial profile showed a dynamic microbiome established at Phase I of the operation, with ahigh decrease in the abundance of Ignavibacterium from the initial biomass to the granules formedand an increase in Actinobacteria, Cytophagia, Flavobacteria, and Alphaproteobacteria in the remainingphases of the bioreactor operation.
- Bioaugmented aerobic granular sludge reactor with a dye-decolorizing yeast for dye removal from textile industry wastewaterPublication . Mendes, Marta; Moreira, Irina; Moreira, Patrícia; Pintado, Manuela; Castro, PaulaTextile industry is a worldwide economic activity that generates high volumes of harmfuleffluents used in fabric processing that are discharged in the environment causing potentialdamages to the aquatic ecosystems [1]. These discharged effluents loaded with synthetic dyes,salt and other chemicals, are resistant to biodegradation and persistent in water, and areresponsible for toxicity and mutagenic effects on the aquatic life [2]. Biological methods aregenerally considered more environmentally friendly and of major relevance [3]. Therefore,biological alternatives to aid the decolorization of dyes in textile wastewaters need to beimplemented. Aerobic granular sludge (AGS) technology has excellent potential inbiodegradation of many pollutants, due to the anoxic/anaerobic zones within granules and theirincreased tolerance to toxicity [4].The aim of this study is to assess the effectiveness of decolorization of textile effluents using abioaugmented aerobic granular sludge reactor. A proved decolorizing yeast, isolated from atextile wastewater treatment plant, was selected for its dye decolorization capacity, and usedto bioaugment the bioreactor while forming the granules from activated sludge. Theincorporation of the yeast with the granules was followed by plating and following the yeastwithin the microbial community. A commonly used textile azo dye was added to the reactor tofollow the biodegradation by the bioaugmented aerobic granular sludge and the efficiency ofthe process in decolorizing the effluent at varying operational parameters was followed to assessif this is a solution for a safer discharge of such effluents.

- Building granite characterisation, construction phases, mason’s marks and glyptography of Nossa Senhora de Guadalupe Church, Mouçós e Lamares, Galicia-North Portugal EuroregionPublication . Freire-Lista, David M.; Campos, Bruno B.; Moreira, Patrícia; Ramil, Alberto; López, Ana J.The Romanesque church of Nossa Senhora de Guadalupe of Mouçós e Lamares is located in Vila Real (North of Portugal). The exterior part of its nave is preserved almost unaltered. Most of the granite ashlars and corbels that make up this church have a mason’s mark in the centre of their faces. The building granites (Sanguinhedo and Vale das Gatas) have been identified and characterised petrographically and petrophysically. The mason’s marks have been as well identified; all the ashlars with visible mason’s marks have been mapped, and a glyptographic study has been carried out. In addition, the surface roughness of ashlars was measured. All these analyses have made it possible to locate the main historical quarry, to calculate the number of stonemasons who worked in the construction of the church, and to determine its construction phases. There are eight main types of mason’s marks on the nave façades. The quarrymen extracted the main building granite (Sanguinhedo granite) from the same quarry, or from nearby quarries. Although the most experienced stonemason has been identified, most stonemasons worked as a team during all construction phases of the church. Techniques such as petrography, ultrasonic P wave velocity, colourimetry, roughness and the determination of hydric properties will guarantee the quality and durability of the heritage stone for restorations. In addition, the glyptographic analysis revealed important historical and ethnographic findings that will be very useful for the appreciation of the monument. Therefore, the knowledge of built heritage, such as mason’s marks contribute to the conservation of historical quarries and traditions, as well as help understand the close cultural association societies have had with heritage stones. In this way, the scientific corpus of historical-cultural heritage can face for the development of tourism in Galicia-North Portugal Euroregion in a long-lasting sustainable way.
