Data mining assessment of Poaceae pollen influencing factors and its environmental implications
No full textPoaceae pollen is highly allergenic, with a marked contribution to the pollen worldwide allergy prevalence. Pollen counts are defined by the species present in the considered area, although year-to-year oscillations may be triggered by different parameters, among which are weather conditions. Due to the predominant role of Poaceae pollen in the allergenicity in urban green areas, the aim of this study was the analysis of pollen trends and the influence of meteorology to forecast relevant variations in airborne pollen levels. The study was carried out during the 1993–2020 period in Ourense, in NW Iberian Peninsula. We used a volumetric Lanzoni VPPS 2000 trap for recording Poaceae airborne pollen grains, and meteorological daily data were obtained from the Galician Institute for Meteorology and Oceanography. The main indexes of the pollen season and their trends were calculated. A correlation analysis and ‘C5.0 Decision Trees and Rule-Based Models’ data mining algorithm were applied to determine the influence of meteorological conditions on pollen levels. We detected atmospheric Poaceae pollen during 139 days on average, mainly from April to August. The mean pollen grains amount recorded during the pollen season was 4608 pollen grains, with the pollen maximum peak of 276 pollen/m3 on 27 June. We found no statistically significant trends and slight slopes for the seasonal indexes, similarly to previous Poaceae studies in the same region. The calculated C5.0 model offered defined results, indicating that the combination of mean temperature above 17.46 °C and sunlight exposure higher than 12.7 h is conductive to significantly high pollen levels. The obtained results make possible the identification of risk moments during the pollen season for the activation of protective measures for sensitized population to grass pollen.Xunta de Galicia | Ref.

Interpreting the genomic landscape of speciation: a road map for finding barriers to gene flow
No full textSpeciation, the evolution of reproductive isolation among populations, is continuous, complex, and involves multiple, interacting barriers. Until it is complete, the effects of this process vary along the genome and can lead to a heterogeneous genomic landscape with peaks and troughs of differentiation and divergence. When gene flow occurs during speciation, barriers restricting gene flow locally in the genome lead to patterns of heterogeneity. However, genomic heterogeneity can also be produced or modified by variation in factors such as background selection and selective sweeps, recombination and mutation rate variation, and heterogeneous gene density. Extracting the effects of gene flow, divergent selection and reproductive isolation from such modifying factors presents a major challenge to speciation genomics. We argue one of the principal aims of the field is to identify the barrier loci involved in limiting gene flow. We first summarize the expected signatures of selection at barrier loci, at the genomic regions linked to them and across the entire genome. We then discuss the modifying factors that complicate the interpretation of the observed genomic landscape. Finally, we end with a road map for future speciation research: a proposal for how to account for these modifying factors and to progress towards understanding the nature of barrier loci. Despite the difficulties of interpreting empirical data, we argue that the availability of promising technical and analytical methods will shed further light on the important roles that gene flow and divergent selection have in shaping the genomic landscape of speciation.Fundação para a Ciência e a Tecnologia | Ref.

Sport practice with friends and perceived physical competence as predictors of physical activity in adolescents
No full textUnderstanding which factors influence participation in physical activity is essential for the development and improvement of public health intervention. The aim of this study was to provide an explanatory prediction model for physical activity level in adolescents, involving a number of influencing variables. 576 participants took part in the study: 275 boys and 301 girls aged between 12 and 18 years old (M = 14.80; SD = 1.180). They attended one of the 11 selected schools from Galicia (Spain), chosen by sampling in the seven main urban areas in that region. The International Questionnaire on Physical Education, Health and Lifestyle was administered. The findings revealed that age, sex, physical perceived competence and sport practice with friends had statistically significant influence on physical activity index. By contrast, the influence of perception of physical attractiveness could not be confirmed. Sport practice with friends and physical perceived competence were the main predicting variables for physical activity level. All this knowledge must be taken into account by physical activity and sport professionals, such as teachers or trainers. Likewise, to improve physical perceived competence, it is essential to offer a wide variety of activities, to propose different levels of problem resolution, to help students make adaptive causal attributions based on effort, and to break gender stereotypes. Strategies involving school mates or friends in different PA and sport projects are needed

Transcranial direct current stimulation for post-stroke dysphagia: a meta-analysis
No full textBackground: Strokes may cause some swallowing difficulty or associated dysphagia in 25–80% of patients. This phenomenon has been linked to increased morbidity and mortality . Therefore, the aim of this study was to evaluate the efficacy of transcranial direct current stimulation in patients with dysphagia in post-stroke patients. Methods: A systematic search in PubMed, Scopus, Web of Science and MEDLINE was conducted. The articles must have to evaluate an intervention that included transcranial direct current stimulation; the sample had to consist exclusively of patients with post-stroke dysphagia; and the experimental design consisted of randomized controlled trial. Difference in mean differences and their 95% confidence interval were calculated as the between-group difference in means divided by the pooled standard deviation. The I 2 statistic was used to determine the degree of heterogeneity. Results: Of the 9 investigations analyzed, all applied transcranial direct current stimulation in combination with conventional dysphagia therapy to the experimental group. All the studies analyzed identified improvements in swallowing function and meta-analysis confirmed their strong effect on reducing the risk of penetration and aspiration (Hedges’s g = 0.55). The results showed that participants who received transcranial direct current stimulation significantly improved swallowing function. Conclusions: Transcranial direct current stimulation has positive effects in the treatment of poststroke dysphagia by improving swallowing function, oral and pharyngeal phase times and the risk of penetration and aspiration. Furthermore, its combination with conventional dysphagia therapy, balloon dilatation with catheter or training of the swallowing muscles ensures improvement of swallowing functio
Multi-objective utilization of wood waste recycled from construction and demolition (C&D): Products and characterization
No full textProducing energy and higher value bio-products from waste materials has been proposed as an economically viable opportunity in the renewable energy sector. However, several challenges associated with the integrated biomass conversion processes remain to be resolved. The present study introduces a multi-faceted plant production of thermal energy and biochar from construction and demolition (C&D) wood chips. The overarching objective of the study is to reduce waste materials while simultaneously producing a self-independent clean thermal energy resource along with value-added co-products such as biochar, biogases and/or activated carbon. The combined thermal energy and slow pyrolysis unit relies on 95% of its energy from waste wood chips to produce thermal energy and high value carbon products. The system not only supplies the energy required for the indirect pyrolysis unit but also provides a major portion of thermal energy demanded for the site. A multi-purpose objective of wood waste management, energy production from waste material, high-quality biochar from waste wood (over 80% carbon), and carbon offsets is demonstrated through the utilization of this plant by addressing some of the major previously problems and challenges faced. The information is useful for techno-economic and life cycle analysis in the next study

This article presents “Mércores de Arte” (2016-2022), a project designed to meet the needs of a group of 4th-year preschoolers, including one deaf student and another with disruptive behavior, using the museum as an alternative learning environment to encourage participation and comprehensive development. The aim of this article is to analyze, from a retrospective perspective, the educational potential of the mu-seum as an integrated setting in the teaching-learning process. It also seeks to reflect on the role of artistic language as a key tool for inclusive communication and attention to diversity. The methodology used is based on a qualitative action research approach. This approach involves the active participation of all stakeholders, integrating reflection and action through an arts-based educational proposal. The data collection techniques used were participant observation and interviews. Tools such as SWOT analysis and photographic records were used to analyze the information. The results showed that the experiences in the museum and art spaces provided an effective response to the individual and group needs of the students, transcending the established curriculum framework. The ar-tistic experience fostered physical and emotional connection, promoting individual and collective recogni-tion through the production, expression, and communication of lived experiences. In conclusion, the integration of the museum as a “classroom outside the classroom” through teaching work is revealed as a key strategy for education. This practice not only enriches students’ cultural literacy but also facilitates transformative, inclusive, and creative learning experiences
