Abstract Introduction: Palliative care at home, combined with multiprofessional work and the presence of a family caregiver, enables the achievement of autonomy and creative alternatives in caregiving. Objective: To understand the conditions related to becoming the main caregiver of a family member receiving palliative care at home. Method: Qualitative research, using Strauss and Corbin's methodological perspective of Grounded Data Theory. In-depth interviews were conducted, with 18 participants: nine family caregivers and nine nursing professionals from a Home Care Service, and were analyzed them by open, axial and selective coding. Subsequently, the categories identified in a conversation with fifteen family caregivers and nine professionals are presented for theoretical validation. Results: The process of becoming a family caregiver is related to three analytical subcategories: "Engaging in the home care of the dependent family member"; " (Un) knowing the health condition of the family member and the meaning of palliative care," and "Experiencing palliative care and coping with the possibility of death". It is emphasized that family members became caregivers due to the imperative need for care of a relative. The understanding of the meaning of palliative care was instituted by the experience of this family member, by the daily treatment of the condition, and the possibilities of death, mediated by the Home Care team, especially the nursing professionals. The professionals working in the service showed difficulties in addressing the theme of death and palliative care with patients and caregivers. Conclusion: Becoming a family caregiver is a complex process, permeated by different interactions between patients, family caregivers and health professionals. It was identified that the difficulties in this process can be mitigated through strategies adopted by professionals to expand the communication and the support for the specific needs of families and, also, through the implementation of public policies that favor the caregiver.

ABSTRACT The production of seedlings of forest species for reforestation of biomes is a practice that restores the conditions of the environment, but water and substrates that favor the growth of seedlings are required. However, in the semi-arid region, water is a limiting factor, requiring the use of alternative sources such as treated domestic sewage. In this context, the objective was to evaluate the growth of Anadenanthera colubrina L. seedlings produced in substrates (soil + bovine manure and soil + coconut fiber) fertilized with treated domestic sewage effluent diluted in public-supply water in proportions (100, 75, 50 and 25% of domestic effluent) and using water from the supply network as a control. The treatments were arranged in a completely randomized design, in a split-plot with three replicates. The treated domestic effluent (TDE) used in the experiment came from the domestic sewage treatment plant of the decanter-digester type of the Projeto de Assentamento Milagre Apodi/RN. The study was conducted in a seedling production nursery at UFERSA, with growth and vigor evaluations at 30, 60, 90 and 120 days after transplanting. The production of seedlings fertigated with domestic effluent caused differences in all growth variables, with improvement in phytomass production. Seedlings fertigated with a dilution of 50% TDE and 50% water supply showed better results when produced with substrate composed of soil and coconut fiber. The seedlings showed good quality, and those cultivated with 50% and 75% of wastewater showed better quality after 120 days of cultivation.

RESUMO A produção de mudas de espécies florestais para reflorestamento de biomas é uma prática que restaura as condições do meio, porém é necessário água e substratos que favoreçam o crescimento das mudas. Entretanto, na região semiárida a água é um fator limitante sendo necessário uso de fontes alternativas como os esgotos domésticos tratados. Neste sentido, objetivou-se avaliar o crescimento de mudas de angico produzidas em substratos (solo + esterco bovino e solo + fibra de coco) fertigadas com efluente de Esgoto Doméstico Tratado (EDT) e diluídos em água de abastecimento nas proporções (100, 75, 50 e 25% do EDT) e água de abastecimento (testemunha). Os tratamentos foram dispostos em delineamento inteiramente casualizado, em parcelas subdivididas com três repetições. O efluente EDT utilizado no experimento foi proveniente da estação de tratamento de esgoto doméstico do tipo decanto digestor do Projeto de Assentamento Milagre Apodi/RN. O estudo foi realizado em viveiro de produção de mudas da UFERSA, sendo realizadas avaliações de crescimento e vigor aos 30, 60, 90 e 120 dias após o transplantio. A produção de mudas fertigadas com efluente doméstico promoveu diferenças em todas as variáveis de crescimento com melhoria na produção de fitomassa. As mudas fertigadas com diluição de 50% do EDT e 50% água de abastecimento proporcionaram melhores resultados quando produzidas com o substrato composto por solo e fibra de coco. As mudas apresentaram-se como de boa qualidade e as cultivadas com 50% e 75% de água residuária mostraram-se com maior qualidade aos 120 dias de cultivo.

ABSTRACT The objective of this work was to evaluate the growth in plant height, stem base diameter, survival rate, and ecophysiology of Acacia mangium and Mimosa caesalpiniifolia plants with and without inoculation with arbuscular mycorrhizal fungi (Rhizophagus clarus) in areas degraded by mining in the municipality of Itaporanga D’Ajuda, SE, Brazil. The experiment was conducted with plants grown with spacing of 3 × 3 m in areas degraded by sand and gravel mining in Itaporanga D’Ajuda, using plants of the species Acacia mangium and Mimosa caesalpiniifolia. Four treatments were used: Acacia mangium without AMF; Mimosa caesalpiniifolia without AMF; Acacia mangium with AMF; Mimosa caesalpiniifolia with AMF. Plants from each treatment were evaluated for plant height, stem base diameter, survival rate and ecophysiological parameters at 12 months after planting. The forest legume Mimosa caesalpiniifolia inoculated with mycorrhizal fungi (Rhizophagus clarus) presented the best results in plant height, survival rate, and photosynthetic efficiency, at twelve months after planting. Plants in the treatment with Acacia mangium without inoculation with mycorrhizal fungi (Rhizophagus clarus) had the largest stem base diameters and second highest plant heights. However, the lowest survival rate of the plants may have caused overestimation of the results of stem base diameter and plant height.

RESUMO O objetivo deste estudo foi avaliar o crescimento em altura, diâmetro, a taxa de sobrevivência e a ecofisiologia de Acacia mangium e Mimosa caesalpiniifolia inoculadas com fungos micorrízicos arbusculares (Rhizophagus clarus) e sem inoculação em área degradada de mineração no município de Itaporanga D’Ajuda, SE. O experimento foi implantado no espaçamento de 3x3 m em uma área degradada por mineração de areia e cascalhos no município de Itaporanga D’Ajuda, SE com as espécies Acacia mangium (Acacia) e Mimosa caesalpiniifolia (Sabiá). Foram definidos quatro tratamentos: Acacia mangium sem FMA; Mimosa caesalpiniifolia sem FMA; Acacia mangium com FMA; Mimosa caesalpiniifolia com FMA. As plantas de cada tratamento foram avaliadas quanto à altura da planta, diâmetro da base do caule, taxa de sobrevivência e parâmetros ecofisiológicos aos 12 meses após o plantio, utilizando 5 plantas selecionadas ao acaso por tratamento. Doze meses após o plantio conclui-se: a leguminosa florestal Mimosa caesalpiniifolia inoculada com fungos micorrízicos Rhizophagus clarus apresentou os melhores resultados em altura, taxa de sobrevivência e eficiência fotossintética. A Acacia mangium sem inoculação com fungos micorrízicos Rhizophagus clarus teve o maior diâmetro e a segunda maior altura. Porém a menor taxa de sobrevivência pode ter superestimado os resultados de diâmetro e altura.

ABSTRACT Salinity can have detrimental effects on plant development. To minimize this damage, strategies such as balanced maintenance of plants’ nutritional status have been proposed previously. The objective of this study is to investigate whether the optimization of foliar nitrogen fertilization can promote the growth and photochemical efficiency of purple basil subjected to salt stress. The experiment was performed using a randomized block design with an incomplete 5 × 5 factorial arrangement generated through experimental matrix Central Composite Design with two parameters: salinity of irrigation water at 0.5, 0.81, 2.75, 4.69, and 5.50 dS m-1; and nitrogen doses at 0, 58.58, 200, 341.42, and 400 mg L-1. It was found that an increase in the salinity of irrigation water reduced the growth and photochemical efficiency of purple basil. However, the foliar application of nitrogen at the concentration of 400 mg L-1 attenuated the harmful effects of salinity on both the absolute and relative growth rates of stem diameter, the relative growth of plant height, and chlorophyll A fluorescence. These results showed that foliar nitrogen fertilization is a suitable strategy to help mitigate salt stress in basil plants.

RESUMO A salinidade pode promover efeitos danosos ao desenvolvimento vegetal, sendo o necessário o uso de estratégias para minimizar os danos promovidos, como a manutenção equilibrada do estado nutricional da planta. Assim, o objetivo deste estudo foi avaliar o efeito da adubação nitrogenada foliar e da salinidade no crescimento e eficiência fotoquímica de manjericão roxo. O experimento foi conduzido com o delineamento de blocos casualizados, em arranjo fatorial incompleto 5 × 5 (salinidades da água de irrigação: 0,5; 0,81; 2,75; 4,69 e 5,50 dS m-1 × doses de nitrogênio: 0; 58,58; 200; 341,42 e 400 mg L-1), gerados através da matriz experimental Composto Central de Box. O aumento da salinidade da água de irrigação reduz o crescimento e a eficiência fotoquímica das plantas de manjericão roxo. Todavia, a aplicação foliar de 400 mg L-1 de N atenuou os efeitos deletérios da salinidade sobre as taxas de crescimento absoluto e relativo para o diâmetro do caule e relativo para a altura de plantas, assim como na fluorescência da clorofila a. Esses resultados mostram que a adubação foliar nitrogenada é uma estratégia para mitigar o estresse salino em plantas de manjericão.

ABSTRACT Paricá is a native tree to the Amazon region recognized for several socioeconomic applications. However, there are few studies on the influence of irrigation regime in the seedling stage. Thus, the objective of the research was to evaluate the effect of water depths and irrigation frequency on the development of Paricá seedlings in the edaphoclimatic conditions of the Amazon region. The experiment was conducted in a greenhouse at the Federal Rural University of the Amazon (UFRA), Capitão Poço Campus, located in Capitão Poço, Pará, Brazil. The experimental design was randomized blocks, in 5x2 factorial arrangements, consisting of five irrigation depths and two irrigation frequencies, with four replications. The highest irrigation depth (725 mL) at daily frequency resulted in lowest biomass production maybe due to hypoxia in the root zone. In contrast the every three day irrigation promoted high biomass production with the highest irrigation depth (725 mL). Contrarily, 435 mL depth produces high quality seedlings at daily irrigation frequency. Regarding the rational use of water, producers may use 725 mL at 3-day frequency, given that it has promoted high seedling quality and provides savings of 580 mL compared to the best water depth on the daily irrigation (435 mL).

Abstract The motivation of this work is to investigate two technological AI paths, evaluate the performance, and discuss the results. Using a covid-19 chest X-ray images databank, we address the two distinct experiments to this problem: (1) an investigation of feature extraction and classification using machine learning algorithms and (2) an approach based on transfer learning used in state-of-the-art applications. For the implementation of our proposal (1), an integrated framework consisting of 25 algorithms with different characteristics was developed to extract features from chest X-ray images. Following this path, we seek to focus on the spatial spectral signatures of shape, texture, local and global statistical quantities. The extraction of features based on information in Fourier and wavelet space-frequency domain was also implemented as part of the framework. On the other hand, several transfer learning CNN’s were also used to evaluate performance and to compere to the first technological path results. Furthermore, the performance of other results reported by various other works are provided. The comparative performance evaluation demonstrated that the two concepts for a computational intelligence tool can produce very good results even working in high-dimensional vector spaces.

CONCLUSION: The eye-tracking provides insights for innovative approaches to promote evidence-based practices and new interventions through self-directed learning and metacognition skills that could be helpful in mathematics education. CONTRIBUTION: This article provides insight into eye-tracking system utility in educational research regarding the mathematics teaching-learning process.

Abstract Disorderly use of water resources has led to depletion, causing environmental and social issues. A relevant aspect to be observed in water supply systems is physical losses which occur during the system’s entire operational process. Many different software packages allow simulations of pressures and flow in water networks. The most used is EPANET. The epanet2toolkit is a recently developed R package that performs the interaction between EPANET and R. Based on this tool, a set of functions is developed to study and evaluate a theoretical network. The objective is to find an ideal network configuration (design) mainly for pressure management which simultaneously reduces physical losses. Water network parameters, such as roughness, reservoir levels, and diameters are used as parameters. A Monte Carlo simulation is generated, based on random values of these network parameters. From these, an ideal pressure scenario is found, resulting in a reduction of 11.6% in the occurrence of physical losses concerning the base case.

Resumo O uso desordenado dos recursos hídricos tem levado ao esgotamento, resultando no surgimento de questões ambientais e sociais. Um aspecto relevante a ser observado nos sistemas de abastecimento de água são as perdas físicas que ocorrem durante todo o processo operacional do sistema. Muitos pacotes de software diferentes permitem simulações de pressões e fluxos em redes de água. O mais utilizado é o EPANET. O epanet2toolkit é um pacote R recentemente desenvolvido que realiza a interação entre EPANET e R. Com base nesta ferramenta, são desenvolvidos um conjunto de funções para estudar e avaliar uma rede teórica. O objetivo é encontrar uma configuração de rede ideal (projeto) principalmente para gerenciamento de pressão que reduza simultaneamente as perdas físicas. Os elementos da rede hídrica, como rugosidade, níveis dos reservatórios e diâmetros são utilizados como parâmetros. Uma simulação de Monte Carlo é gerada, com base em valores aleatórios dos parâmetros desta rede. A partir destes, é encontrado um cenário de pressão ideal, resultando em uma redução de 11,6% na ocorrência de perdas físicas em relação ao caso base.

Abstract In this research, aqueous and ethanolic extracts from Justicia pectoralis Jacq and Croton Jacobinensis Baill were characterized. The UPLC-QTOF-MSE analysis was performed on the extracts identified, predominantly, flavonoids, tannins and acids. The extracts did not indicate toxicity in human epithelial cells. C. jacobinensis presented a concentration of phenolics 60.5% higher than J. pectoralis in all scenarios evaluated and, for both samples, the hydroalcoholic extract at 70% exhibited the best efficiency in the extraction (14501.3 and 32521.5 mg GAE 100 g-1 for J. pectoralis and C. jacobinensis, respectively). The antioxidant activity presented a positive correlation with the concentration of phenolics, being 1.186,1 and 1.507,9 μM of Trolox for J. pectoralis and C. jacobinensis at 70% of ethanol; however, it was not verified statistical difference between the ethanolic solutions (p < 0.05). The antimicrobial activity of J. pectoralis extracts was highlighted once was the most effective against gram-positive bacteria. The results suggest that both J. pectoralis and C. jacobinensis extracts present the potential to be applied as natural additives due to their antioxidant and antimicrobial activity and safety. Thus, it is suggesting the development of studies that could investigate the interaction of these plant extracts with food matrices is required.

Abstract This work aims to evaluate, at different stages, the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix Coturnix), consuming diets with increasing levels of seaweed bran (Sargassum sp). A total of 240 European quail chicks (Coturnix coturnix Coturnix) were distributed in a completely randomized design, with four levels of bran inclusion (0.0, 2.5, 5.0, and 7.5%), 6 replications with 10 birds in each experimental plot. In the period from 1 to 21 days, the feed intake of the control group was higher, with lower water consumption. In the period from 22 to 42 days, feed and water consumption increased with the inclusion of seaweed, but with a reduction in weight gain. In the total period, water consumption was higher at the level of 2.5 and 7.5%, with lower consumption in the control group, with a small reduction in slaughter and carcass weight with the inclusion of bran. There was no difference (P > 0.05) in carcass quality and intestinal biometry. We recommended the inclusion of up to 7.5% of sargassum meal in the diet of European quails at all stages, without compromising its productive performance, carcass quality, and intestinal biometry.

ABSTRACT: Methods in cognitive neuroscience can assist educational planning of teachers in the context of Special Education, as they favor personalized practices that value individual students with Autism Spectrum Disorder (ASD) and/or Intellectual Deficiency (ID). Therefore, this study aimed to verify the feasibility of using functional near-infrared spectroscopy (fNIRS) in clinical naturalistic situation with children and young people with ASD and/or ID during teaching tasks. In addition, the study sought to identify training strategies so that children and young people use the equipment during the activity. Seven students diagnosed with ASD and/or ID were trained with mathematics, reading and emotional expressiveness, according to their respective previous educational curricula. Each participant was exposed to two tasks in each activity, one in which he/she already had a domain and one that needed support to issue an independent response. The results indicated the feasibility of using fNIRS in this natural context of the child and the young student and provided implicit measures beyond the observational arrangement measures and task error. This is an important demonstration of the feasibility of using fNIRS in experiments in the context of Special Education.

RESUMO: Métodos em neurociência cognitiva podem auxiliar o planejamento educacional de docentes no contexto da Educação Especial, por favorecerem práticas personalizadas que valorizem a velocidade individual de aprendizagem de estudantes com transtorno do espectro do autismo (TEA) e/ou deficiência intelectual (DI). Assim sendo, este estudo objetivou verificar a viabilidade de uso da Espectroscopia Funcional de Infravermelho Próximo (fNIRS) em situação naturalística clínica com crianças e jovens com TEA e/ou DI durante tarefas de ensino. Ademais, o estudo buscou identificar as estratégias de treino para que as crianças e os jovens utilizassem o equipamento durante a realização da atividade. Sete estudantes com diagnóstico de TEA e/ou DI foram treinados com atividades de matemática, leitura e expressividade emocional, de acordo com seus respectivos currículos educacionais prévios. Cada participante foi exposto a duas tarefas em cada atividade, uma na qual já apresentava domínio e outra que necessitava de apoio para emitir uma resposta independente. Os resultados indicaram a viabilidade de uso do fNIRS nesse contexto natural da criança e do jovem e forneceram medidas implícitas para além das medidas observacionais de acerto e erro na tarefa. Esta é uma importante demonstração da viabilidade do uso do fNIRS em experimentos no contexto da Educação Especial.

Abstract Worm infections pose a significant challenge to goat farming in the tropics. While individual variations in the animals' response to this disease are observed, understanding its genetic component is crucial for establishing effective herd production management, prioritizing the selection of goats with higher resistance to parasitism. This study aimed to assess goat response to worm infection under natural field conditions using data on eggs per gram of feces (EPG), body condition score (BCS), and conjunctival mucosa coloration (FAMACHA©). Cluster analysis and artificial intelligence (AI) techniques were applied to 3,839 data points from 200 individuals in an experimental goat herd in Piauí, Brazil. The study considered the phenotypic expression of resistance, sensitivity, and resilience to worm infection as responses to parasitism. Three clustering methods, namely Ward, Average, and k-means, were employed and compared with fuzzy logic obtained through the CAPRIOVI web software. The analysis revealed statistically significant differences (P<0.05) between the groups of animals classified as resistant, resilient, and sensitive to parasitism. Pregnancy and peripartum were identified as stages of heightened sensitivity to parasitism (P<0.05). Among the clustering techniques, traditional statistical methods exhibited excellent performance, with an overall accuracy percentage exceeding 90.00%. In contrast, CAPRIOVI's fuzzy logic demonstrated lower overall accuracy (77.00%). The clustering methods showed similar efficiency, but differed in terms of the distribution of animals per group, with a tendency towards greater numbers in the resistant category. Fuzzy logic circumvented this limitation by enabling the formation of groups tailored to meet the producer's interests, adding consistency in terms of the animals' response to worm infection. This finding highlights the potential of the software for goat health management.

Resumo A incidência de verminose é um dos principais obstáculos para a caprinocultura nos trópicos. A variação individual da resposta do animal à enfermidade existe, mas precisa ser determinado o seu componente genético e estabelecer o manejo zootécnico dos rebanhos, priorizando a seleção de animais mais resistente ao parasitismo. Objetivou-se nesse estudo avaliar a resposta de cabras à incidência de verminose sob condições de infecção natural a campo, com informações de ovos por grama de fezes (OPG), escore da condição corporal (ECC) e grau de coloração da mucosa conjuntiva (FAMACHA©), recorrendo a utilização de análise de agrupamento e a aplicação de inteligência artificial (IA). Foram utilizadas 3.839 informações de 200 indivíduos em um rebanho experimental de caprinos no Piauí. Considerou-se como resposta ao parasitismo a expressão fenotípica de resistência, sensibilidade e resiliência a verminose, submetidos a três métodos de agrupamento: Ward, Average e K-means, comparado com a lógica Fuzzy, obtidos com o software web CAPRIOVI. Os resultados demonstraram que os grupos de animais resistente, resiliente e sensível ao parasitismo foram estatisticamente distintos (P<0,05). As cabras durante a gestação e o periparto foram identificadas como fases de maior sensibilidade ao parasitismo (P<0,05). O CAPRIOVI aplica a lógica Fuzzy e apresentou o menor percentual de acerto global (77,00%), enquanto os métodos estatísticos tradicionais se destacaram com percentual de acerto global superior a 90,00%, demonstrando excelência estatística com esse fim. Os métodos de agrupamentos apresentaram semelhança na eficiência, mas diferiram quanto à distribuição de animais por agrupamento, com tendência de maior quantidade na categoria resistente. A aplicação da lógica Fuzzy contornou essa limitação ao direcionar a formação dos grupos visando atender o interesse do produtor, inserindo consistência em termos de resposta dos animais a verminose, qualificando o software com potencial para adequação ao manejo sanitário de caprinos.

ABSTRACT The state of Bahia has the third largest equine herd in Brazil, with the horse industry overtaking several sectors of the economy currently. However, animals may be exposed to several pathogenic agents, especially the equine infectious anemia (EIA) virus. EIA is a persistent viral disease with a worldwide distribution and is considered the main infectious disease in horses. Therefore, this study sought data from serological survey EIA in Itapé and Barro Preto municipalities, inserted in the southern Coastal Identity Territory of Bahia, by using the agar gel immunodiffusion test. A total of 1,880 blood serum samples from Equidae older than 6 months were analyzed from 172 properties. The general prevalence of outbreaks was 25.58% (44/172), presenting 40.47% (34/84) in Barro Preto (cocoa zone) and 11.36% (10/88) in Itapé (livestock zone). The prevalence of positive animals in Itapé was 1.01% and in Barro Preto 12.15%. Each assessed property received a questionnaire with emphasis on sanitary management and a booklet containing basic disease information. It was concluded the EIA is endemic in two epidemiologically distinct areas in the Southern Coastal Identity Territory of Bahia, one with a high prevalence in the cocoa zone for both animals and properties, and the other, in livestock zone, with a significantly low prevalence for animals, however also high for properties. Regarding the risk factors, there was a correlation between the species and age of the animals. Mules and the elderly showed a significant association, probably due to the habitat they live in and longer exposure to the virus.
