- Detection and identification of fungal species by electronic nose technology: A systematic reviewPublication . Mota, Inês; Teixeira-Santos, Rita; Cavaleiro Rufo, JoãoA rapid and effective identification of fungal species is essential for numerous applications, and electronic nose systems are being proposed as suitable alternatives to currently available fungi identification techniques. Hence, the present review aims to unveil all published information concerning fungi identification by electronic nose systems. A systematic review of the literature was conducted according to the PRISMA guidelines. A total of 16 articles met the inclusion criteria and were included in the analysis. The results of the reviewed studies demonstrated that effective detection of fungi was possible through sensor-based electronic nose systems, which may actually function as a mycotoxin screening tool for several applications. The obtained results suggest that the sensor-based electronic nose systems may not only screen different fungi genera, but also identify the associated species. This technology has already been experimented in several fields, from food industry to clinical practice. By summarizing these results, the present review may accelerate the standardization of electronic noses in fungi detection and discrimination, allowing a faster and more efficient screening of samples.
- Foliar application of sodium nitroprusside boosts solanum lycopersicum l. tolerance to glyphosate by preventing redox disorders and stimulating herbicide detoxification pathwaysPublication . Soares, Cristiano; Rodrigues, Francisca; Sousa, Bruno; Pinto, Edgar; Ferreira, Isabel M. P. V. O.; Pereira, Ruth; Fidalgo, FernandaStrategies to minimize the effects of glyphosate (GLY), the most used herbicide worldwide, on non-target plants need to be developed. In this context, the current study was designed to evaluate the potential of nitric oxide (NO), provided as 200 µM sodium nitroprusside (SNP), to ameliorate GLY (10 mg kg−1 soil) phytotoxicity in tomato plants. Upon herbicide exposure, plant development was majorly inhibited in shoots and roots, followed by a decrease in flowering and fruit set; however, the co-application of NO partially prevented these symptoms, improving plant growth. Concerning redox homeostasis, lipid peroxidation (LP) and reactive oxygen species (ROS) levels rose in response to GLY in shoots of tomato plants, but not in roots. Additionally, GLY induced the overaccumulation of proline and glutathione, and altered ascorbate redox state, but resulted in the inhibition of the antioxidant enzymes. Upon co-treatment with NO, the non-enzymatic antioxidants were not particularly changed, but an upregulation of all antioxidant enzymes was found, which helped to keep ROS and LP under control. Overall, data point towards the benefits of NO against GLY in tomato plants by reducing the oxidative damage and stimulating detoxification pathways, while also preventing GLY-induced impairment of flowering and fruit fresh mass.
- Shared PV Production in Energy Communities and Buildings ContextPublication . Ramos, Sérgio; Foroozandeh, Zahra; Soares, João; Tavares, Inés; Faria, Pedro; Vale, ZitaAcross Europe, householders have taken the opportunity to produce their electricity, helping them to reduce their electricity bill as well as reducing carbon emissions, by installing rooftop Photovoltaic Panels (PV) on their buildings. New adequate business models are needed for improving the sharing of PV between consumers in a community. Both technical and economic aspects should be considered in a clear way for consumers to understand and benefit from the community. In this paper, an overview of energy communities is provided to support the innovative PV sharing models for buildings, which are proposed in a way to be clear for community members. The developed concepts are supported by the formulation of the optimization problem to be solved by the community manager.

- Is there a film in this text? The commercial success of Rubem Fonseca's cinematic literaturePublication . Lopes, Helena Isabel da SilvaThis dissertation focuses on the language of film in Rubem Fonseca’s literary fiction. Fonseca’s literature’s complicity with the language of cinema is examined through the appropriation of mass film narrative conventions, the observance of screenplay guidelines and the literary recreation of an illusionist rhetoric of film characterized by fluidity, transparency and immediacy. Effective in producing speed and readability, Fonseca’s assimilation of a cinematic rhetoric subsumable in David Bordwell’s notion of continuity system constitutes a cornerstone of his modality of literary realism, sometimes capable of producing effects of real. Unveiled by means of a transmedial and intercultural approach, the psychological operations of mental imagery during the consumption of this intermedial artifact classified as cinematic literature in the age of post-cinema are described. Fueled by cinema, the accessibility of Fonseca’s broadbrow fiction is framed in a postmodernist protocol of reading capable of crossing the border between high and lowbrow audiences, thus closing a sociologic gap between elites and masses. After assessing the commercial success of Fonseca’s books in Portugal and Brazil, the monography proceeds to exhort publishing houses to extend the marketing of his books to low and middlebrow audiences, with a view to fulfilling the sales potential this research finds in Fonseca’s ingeniously salable transmedial recipe. A strategy for the measurement of the author’s value as an intangible asset of Sextante, Rubem Fonseca’s Portuguese publishing house, is proposed. The microeconomic benefits of such monetization of Intellectual Capital for the company are highlighted. The benefits of increasing the sales of Fonseca’s broadbrow literature at the macroeconomic level are also emphasized with regard to the generation of wealth and increase of sustainability through the extension of literacy.
- Ankle stiffness assessment in individuals with chronic ankle instability in dual-task single leg stance on an unstable surfacePublication . Dias, Nuno; Estupendo, Hugo; Valente, Isabel; Carmo, Luis; Sousa, AndreiaThe shoulder of handball players suffers from the ongoing repetition of movement that may lead to the development of joint instability and modification of proprioceptive condition. Because the articular components of the shoulder joint are considered to have extreme importance on the static and dynamic stabilisation and quality of proprioceptive information, they may compromise the athlete’s performance. The purpose of our study was to verify if shoulder strength parameters (SSP) and joint position sense (JPS) of shoulder internal and external rotation may contribute to the development of shoulder instability in handball players.
- Seaweeds rehydration and boiling: Impact on iodine, sodium, potassium, selenium, and total arsenic contents and health benefits for consumptionPublication . Correia, Helena; Soares, Cristina; Morais, Simone; Pinto, Edgar; Marques, António; Nunes, Maria Leonor; Delerue-Matos, Cristina; Almeida, AgostinhoConsidering the importance of seaweeds for the development of sustainable and innovative food products, this study aimed to characterize the impact of hydrothermal processing on iodine, sodium, potassium, selenium, and arsenic concentrations of four seaweed species (S. latissima, L. digitata, U. pinnatifida, and C. crispus) and on the associated health risks-benefits for consumers. These elements revealed a common pattern for leachable fractions of iodine, total arsenic, and selenium: L. digitata ≥ S. latissima > C. crispus > U. pinnatifida after rehydration and boiling during different periods. The behavior for sodium was: S. latissima > L. digitata > C. crispus > U. pinnatifida, and for potassium: U. pinnatifida > L. digitata > S. latissima > C. crispus. Generally, the species that attained more significant losses were S. latissima and L. digitata. A health-relevant sodium/potassium ratio below 0.7 was found for all species except for U. pinnatifida. In some species, the risk-benefit analysis revealed that high iodine and arsenic levels might promote risks for consumption, even after 20 min boiling, but 5 g of processed U. pinnatifida could contribute to adequate iodine, sodium, potassium, and selenium intakes for all population groups. Standardized processing treatments of seaweeds can open new opportunities for the sector.
- Exploring two food composition databases to estimate nutritional components of whole mealsPublication . Silva, Marta; Ribeiro, Mafalda; Viegas, Olga; Martins, Zita E.; Faria, Miguel; Casal, Susana; Pinto, Edgar; Almeida, Agostinho; Pinho, Olívia; Ferreira, Isabel M.P.L.V. O.The integration of foodomics data to explain the impact of diet on health requires a precise knowledge of nutrients composition of complex meals. This work assesses the adequacy of two food composition databases (FCDBs) for calculation of nutritional composition of whole meals, compared to the golden standard “lab chemical analyses” and search for predictive models to overcome some limitations of FCDBs. Six meals were designed by integrating healthy foods in a meal based on the “Western diet” pattern. The nutritional composition of each meal was i) chemically determined; ii) retrieved from the Portuguese food composition table (TCAP) and from iii) United States Department of Agriculture database (USDA). Compared to chemical analyses, both FCDBs significantly (p < 0.05) overestimate the amount of Na and vitamin B6; TCAP also overestimate the amount of Ca (p < 0.05), while USDA overestimate energy, fat, available carbohydrates, P, and Fe. Linear regression analyses were used to adjust nutrient values based on TCAP and USDA. Predictive models from both FCDBs were successfully obtained for reliable estimation of protein, PUFA, available carbohydrates, total carbohydrates, sugars, Zn, β-carotene, vitamin E, riboflavin, and niacin in meals with a given uncertainty, which is provided by the respective correction factors. Those predictive models are limited to the range of theoretical values of meals studied.
