Conceptual vision of the smart energy system
Authors:   Institute of Industrial Economics of the NAS of Ukraine, Serdiuk Oleksandr , Andriienko Bohdan ,   Institute of Industrial Economics of the NAS of Ukraine
Published: June 2024

In modern scientific and political circles, the smart energy system is considered as an integral component of Industry 4.0, since in a broad sense it serves the purpose of increasing production efficiency due to the introduction of artificial intelligence technologies. However, currently there is no single, established vision regarding the meaning of the term "smart energy system". As a rule, it is viewed through the prism of separate, often unrelated technological processes, which complicates the development of consistent theoretical provisions and practical recommendations for the development of Industry 4.0. The purpose of the article is the systematization of scientific views on certain aspects of the application of digital technologies in the field of energy and the development of a holistic conceptual vision of a smart energy system. The key elements of the smart energy system consist of smart energy generation, as a set of digitalization measures for the control system of energy generating facilities, aimed at increasing the specific production of electricity, as well as adjusting the load within the nodes of electricity production from renewable sources with the aim of stabilizing the energy flow; smart synchronization, which is designed to distribute the load among the energy sectors on the basis of an intelligent assessment of system needs and capabilities; smart distribution, which optimizes the operation of distribution networks based on data analysis of temporal and spatial trends in the electricity transmission system; and smart consumption, which involves the implementation of technological measures that create conditions for economical consumption of electricity. The holistic vision of the "smart energy system" concept, which provides for the comprehensive implementation of measures provided for by the micro-concepts of smart energy generation, smart synchronization, smart distribution and smart consumption, is substantiated. It is argued that the implementation of the “smart energy system” concept will ensure a synergistic effect of economical utilization of energy resources.

Metabolic dysregulation and obesity are associated with many metabolic alterations, including impairment of insulin sensitivity and dyslipidemia. Recent studies highlight the key role of phosphatidylinositol 3,4,5-triphosphate-dependent Rac exchange proteins (PREX proteins) in the pathogenesis of obesity, advocating further elucidation of their potential therapeutic implications. The present study aimed to estimate the serum level of PREX proteins and its potential association with insulin resistance markers and plasma lipids level in obese and overweight non-diabetic patients. The study included 30 persons classified as obese, 30 as overweight, and 30 healthy individuals of similar age and gender. The levels of PREX1 and PREX2 were measured using ELISA kits, insulin, fasting glucose, glycosylated hemoglobin and total lipid profile were determined using appropriate photometric kits. HOMA-IR was used as a measure of insulin sensitivity. According to the obtained results, obese non-diabetic patients had higher serum PREX1 level compared to both overweight and normal-weight individuals. PREX1 correlated positively with the markers of insulin resistance and dyslipidemia. PREX2 level was shown to be lower both in obese compared to overweight patients and in overweight compared to normal-weight individuals. PREX2 correlated negatively with the markers of insulin resistance but not with the markers of dyslipidemia. Keywords: dyslipidemia, insulin resistance, obesity, overweight, PREX proteins
A vigilância e a tentativa de controle da ditadura civil-militar sobre as denúncias de violações dos direitos humanos no Brasil
Authors: Fetter da Silva Leonardo
Published: June 2024

Quando observamos a trajetória de afirmação dos direitos humanos no Brasil, compreendemos a ditadura civil-militar (1964-1985) como um momento de grande desafio. Ao mesmo tempo em que foi um período em que violações e crimes foram perpetuados pelo Estado brasileiro e seus agentes de forma sistemática, os direitos humanos passaram, em consequência disso, a ser defendidos por expressivos setores sociais. Portanto, foi um período marcado por esse paradoxo, pela violência e pelas violações, assim como pelo florescimento e aprofundamento social em torno dos direitos humanos no Brasil, principalmente na abertura política, ao final do regime, e na instauração da democracia.

Introduction. Low-fertility soils and high logistics costs for seedling production characterize the Peruvian Amazon. Objective. To evaluate the effect of a combination of sandy soil and oil palm compost on substrate, growth, and nutrition of cocoa seedlings under greenhouse conditions. Materials and methods. The experiment was conducted for 90 days in Yurimaguas-Loreto using a completely randomized design in a 5x5 matrix, with five doses of Oil Palm Compost and Sandy Soil to determine the best combination for cocoa growth and nutrition. Height (cm), diameter (mm), leaf area (cm2), dry weight of stem and root were measured; soil chemical analysis and plant analysis (macro and micronutrients) were also conducted. Results. Sandy soil showed no significant effect on cocoa seedlings, while treatments with oil palm compost promoted shoot and root biomass. Additionally, this compost favored conditions for seedling growth by promoting higher organic matter, available phosphorus, exchangeable calcium, potassium, and higher cation exchange capacity. Regarding cocoa nutrition, it promoted greater absorption of macro and micronutrients in cocoa seedlings. Conclusions. These results indicate that the best treatment was the one composed entirely of oil palm compost, as it promotes growth and nutrition by improving substrate conditions.

Published: June 2024

Q fever has become one of the most common causes of abortion in sheep herds, resulting in significant financial losses for Egyptian farmers. The goal of this study was to establish Coxiella burnetii seroprevalence and molecular detection in three sheep farms in Egypt. A total of 184 sheep of various ages and sexes had their serum samples and vaginal swabs taken. All serum samples were checked for the presence of C. burnetii antibodies by using an ELISA, while 50 vaginal swabs were randomly chosen for molecular detection of the C. burnetii IS1111 gene. The overall seroprevalence of Q fever in sheep was 37.5%, and it was more common in females (39.5%) than in males (8.3%). Antibodies to C. burnetii were found in more than half of pregnant ewes (47.7%). Antibodies to C. burnetii were found in 47.7% of pregnant ewes, compared to 31.4% in non-pregnant and abortive ewes (43.8%). Seroprevalence was observed to be significantly higher in sheep older than 3 years (71.2%). The presence of the C. burnetii IS1111 gene was found in 20% of the molecularly analysed vaginal swabs. Based on the abortion history and pregnancy state of the studied sheep, no statistical significance was identified, since the C. burnetii gene was present in equal percentages in both aborted and non-aborted ewes. A comparison of ELISA and PCR results for vaginal swab samples revealed a statistically non-significant link between the two procedures’ results. These findings revealed sheep as an important reservoir for C. burnetii infection, implying that the role of C. burnetii in sheep should be studied further.

Conclui-se que, em ambos os casos, ocorre a constituição de um processo insidioso e controverso de defesa do Ensino Médio Integrado à Educação Profissional, bem como de sua concepção e, ao mesmo tempo, sua inviabilização.
Understanding Angle and Angle Measure: A Design-Based Research Study Using Context Aware Ubiquitous Learning
Authors: Crompton Helen
Published: June 2024

Mobile technologies are quickly becoming tools found in the educational environment. The researchers in this study use a form of mobile learning to support students in learning about angle concepts. Design-based research is used in this study to develop an empirically-substantiated
local instruction theory about students’ develop of angle and angle measure. This local instruction theory involves real-world connections and mobile technologies through a sub category of mobile learning called context-aware ubiquitous learning. Through a process of anticipation, enactment,
evaluation, and revision, the local instruction theory was developed to include a theoretical contribution of how students come to understand angle and angle measure using context-aware ubiquitous. A set of instructional activities was also developed as an embodiment of that theory. The findings
from clinical interviews indicate that context-aware ubiquitous learning is a valuable mathematical context for introducing students to angle and angle measure.
Antagonistic potential of Trichoderma harzianum and Purpureocillium lilacinum on Ceratocystis fimbriata in soil cultivated with eucalyptus
Authors: Antonio Gabriel Leonardi , Firmino Ana Carolina
Published: June 2024

ABSTRACT Cultivation of eucalyptus is of great importance in Brazil. Ceratocystis wilt is a disease of great economic relevance in the country, affecting eucalyptus, cacao and mango crops. New alternatives are needed for the management of this disease because infected plants frequently have to be removed from the area, causing losses to the farmers. The present study aimed to evaluate the efficiency of biological control agents (Trichoderma harzianum and Purpureocillium lilacinum), applied by different modes, against Ceratocystis fimbriata in the soil. The experiment was conducted in a greenhouse in Dracena – São Paulo State, in two phases: one phase of 4 months with 90-day-old seedlings, and another phase of 2 months with 60-day-old seedlings. The following treatments were performed: Infested soil and soaking (IS + S); Infested soil and hydrogel (IS + H); Infested soil and irrigation (IS + IR); Infested soil and powder (IS + P); Negative Control (NC); Positive Control (CP). Results indicated that plants inoculated with the pathogen and treated with the control agents tended to have a higher chlorophyll index. Treatments with both biological agents applied by irrigation and powder in the soil (IS+IR and IS+P) presented the best and most consistent results for the two tested seedling ages.

RESUMO Introdução: a estenose da artéria carótida interna (ACI) causa cerca de 15% dos acidentes vasculares cerebrais isquêmicos. A ultrassonografia duplex (USD) é a primeira linha de investigação da estenose de ACI, mas sua acurácia varia na literatura e é comum complementar o estudo com outro exame de maior acurácia diante de estenose significativa. Há uma escassez de estudos que comparem a USD com a angiotomografia computadorizada (ATC) na literatura atual. Métodos: realizamos um estudo de acurácia, que comparou a USD à ATC de pacientes de um hospital terciário com um intervalo máximo de três meses entre os exames. Os pacientes foram selecionados retrospectivamente e dois cirurgiões vasculares independentes e certificados avaliaram cada imagem de maneira mascarada. Quando houve discordância, um terceiro avaliador foi convocado. Avaliou-se a precisão diagnóstica da estenose da ACI de 50-94% e 70-94%. Resultados: foram incluídos 45 pacientes e 84 artérias após a aplicação dos critérios de inclusão e exclusão. Para a faixa de estenose de 50-94%, a acurácia da USD foi 69%, sensibilidade 89% e especificidade 63%. Para a faixa de estenose de 70-94%, a acurácia da USD foi 84%, sensibilidade 61% e especificidade 93%. Ocorreu discordância entre avaliadores da ATC com mudança de conduta clínica para cirúrgica em pelo menos 37,5% dos laudos conflitantes. Conclusão: a USD teve uma acurácia de 69% para estenoses de 50-94% e de 84% para estenoses de 70-94% da ACI. A análise das ATC dependeu diretamente do avaliador com mudança de conduta clínica em mais de 37% dos casos.

RESUMO Introdução: o ácido valpróico (VPA), droga epigenética, apresenta-se com potencial para o tratamento de neoplasias. Estudam-se seus efeitos sobre a cicatrização do plano peritônio-músculo-aponeurótico (PMA) da parede abdominal. Método: sessenta ratos Wistar, foram alocados em dois grupos: o experimental (VPA) e o controle (cloreto de sódio 0,9%), tratados diariamente, iniciando três dias antes da intervenção e até a eutanásia. Sob anestesia, fez-se uma laparotomia mediana que foi reparada com dois planos de síntese. As avaliações aconteceram 3, 7 e 14 dias após a cirurgia. Estudou-se a integridade das feridas, a qualidade da reação inflamatória, a intensidade do infiltrado de leucócitos, a síntese do colágeno, a intensidade da angiogênese e a presença de miofibroblastos. Resultados: o plano PMA mostrou-se deiscente em 11 dos 30 animais (p=0,001) do grupo experimento. Não houve diferença na qualidade da reação inflamatória e nem no infiltrado de leucócitos. A imuno-histoquímica revelou, no grupo experimento, menos colágeno I (p3=0,003, p7=0,013 e p14=0,001) e mais colágeno III (p3=0,003, p7=0,013 e p14= 0,001). Colágeno avaliado pelo Sirus Supra Red F3BA mostrou, no grupo experimento,menos colágeno nos três tempo (p<0,001) com menos colágeno I e colágeno III (p<0,001). Constatou-se menor número de vasos no 3º dia (p<0,001) e no 7º dia (p=0,001) e não afetou a quantidade de miofibroblastos. Conclusão: o VPA mostrou deiscências do plano PMA, com reação inflamatória semelhante.ao controle, menor deposição de colágeno total e de colágeno I, menor atividade angiogênica, sem interferir na quantidade de miofibroblastos.

RESUMO Embora a diástase de reto abdominal (DR) tenha sido negligenciada por muito tempo pelos cirurgiões gerais, os cirurgiões plásticos consideravam a abdominoplastia convencional como a única opção de reparo. No entanto, esse cenário mudou recentemente, seja pelo melhor entendimento da correlação entre DR e a função da parede abdominal e o maior risco de recorrência na correção de hérnias abdominais, seja pelo desenvolvimento de novas técnicas minimamente invasivas (MIS) para reparo da DR. Um desses procedimentos cirúrgicos consiste no conceito de abdominoplastia, ou seja, dissecção supra-aponeurótica e plicatura da DR (com ou sem hérnia abdominal), mas realizada através de três pequenas incisões suprapúbicas por laparoscopia ou abordagem robótica. Mais recentemente, esse procedimento ganhou novas etapas. A lipoaspiração e a tecnologia de retração da pele têm sido associadas à plicatura MIS da DR, o que aumenta as indicações da técnica e potencialmente melhora os resultados. Pela primeira vez na literatura, descrevemos essas etapas e a sinergia entre elas.
CONSTRUTO DIDÁTICO DE LEITURA LITERÁRIA NO ENSINO DE PORTUGUÊS COMO LÍNGUA ADICIONAL: UM PERCURSO ENTRE MATERIAIS E MÉTODOS
Authors: Takahashi Neide Tomiko
Published: June 2024

RESUMO A presença da literatura no ensino de línguas adicionais incorpora a premissa de que há consenso sobre a sua importância em sala de aula. No entanto, a hesitação quanto ao modo de abordá-la ainda se projeta nas crenças de professores e pesquisadores, notadamente nos materiais didáticos e nos planejamentos de aulas. Partindo de conceitos da construção de sentidos intercultural em leitura literária nas aulas de português como língua adicional, defende-se que os textos literários são elementos fundamentais no desenvolvimento do processo cognitivo, equilibrando sua dimensão estética e dialógica à leitura de mundo dos estudantes. Nessa perspectiva, na medida em que se fortalece a relação entre mediador, texto literário e leitor, revelam-se modelos estratégicos no planejamento de cursos. Objetiva-se, neste artigo, uma investigação de tais modelos, com o propósito de examinar os procedimentos de ensino de leitura literária para estudantes estrangeiros, baseados em suas experiências de leitura como prática educativa e social. Por meio da análise desses procedimentos em aulas de línguas adicionais, procura-se demonstrar e aperfeiçoar o funcionamento dos mecanismos de mediação além dos limites dos livros didáticos, mas ainda parte integrante de atividades e de materiais de ensino. Como resultado, torna-se possível responder qual o papel da leitura de textos literários no processo de assimilação da língua portuguesa e de que forma o professor pode contribuir em sua prática didática de mediação ao permitir aproximar-se da prática social e construir sentidos, vinculando conhecimento empírico e saberes interculturais.

Published: June 2024

RESUMO A educação linguística crítica com crianças e pesquisas nessa área têm estado em especial evidência na última década (Merlo; Malta, 2022; Tonelli; Kawachi-Furlan, 2021; Malta, 2019; Merlo, 2018; Tonelli; Pádua; Oliveira, 2017). Dada a complexidade do trabalho pedagógico com crianças, pensar a linguageme a educação correlacionadas às práxis pedagógicas torna-se um caminho necessário nos dias atuais. Sendo assim, este artigo tem como principal objetivo compartilhar duas experiências que interligam estudos em tradução (Zaidan, 2012; Arrojo, 2007; Bassnett, 2003) de literatura infantil à educação linguística em inglês com crianças. Ambas as experiências foram realizadas ao longo da elaboração de trabalhos de conclusão do curso de Letras-inglês da Universidade Federal do Espírito Santo. Na primeira delas (Oliveira, 2022), relatamos o processo de tradução da obra literária do escritor Ziraldo (2005), intitulada O Joelho Juvenal. Juntamente à tradução do livro, o referido estudo traz sugestões de uso do material para a prática de ensino de inglês com crianças em uma perspectiva decolonial (Menezes de Souza; Figueiredo; Martinez, 2019; Mignolo, 2018). Em diálogo com esse trabalho de tradução literária, a segunda experiência consistiu na elaboração e desenvolvimento de planos de aula baseados na tradução realizada por Oliveira (2022). Assim, a pesquisa de Silva (2023), além de promover reflexões sobre praxiologias (Pessoa; Silva; Freitas, 2021), tece considerações sobre a relevância da literatura na educação infantil (Tonelli, 2008) e defende que práticas de contação de histórias auxiliam na promoção de um olhar freireano (Freire, 1997; 1996; 1987) para a educação linguística crítica com crianças. Finalmente, refletimos sobre como ambas as experiências colaboram para a formação docente inicial desses estudantes em fase final da graduação, ao mesmo tempo em que cooperaram para a construção de seus próprios currículos e de suas práticas pedagógicas com crianças.

Published: June 2024

ABSTRACT This study analyzes the use of literary texts in three textbooks of Portuguese as an additional language (PAL) adopted by universities in the United States. Specifically, it aims to answer the following research questions: 1) How do the activities based on literary texts promote communication in the target language? 2) What opportunities do the activities offer for the development of literary literacy? 3) How is culture approached in the activities? To address these questions, we consider the following criteria of qualitative analysis: first, modes of communication (interpersonal, interpretive, and presentational), extended discourse, and grammar; second, basic steps of development of literary literacy (i.e., motivation, introduction, and interpretation) and diversity of texts; third, cultural products, practices, perspectives, and the notion of interculturality. Results indicate the textbooks incorporate most aspects examined but inconsistently and in relatively low number of activities.

Published: June 2024

ABSTRACT In this work, the population dynamics and reproductive aspects of two sympatric Hyalella species in a river spring were analyzed in the northwestern state of Rio Grande do Sul, Brazil. The samplings were performed by one person, for ten minutes and using a hand net for one-year period (March 2018 to April 2019) and transported to the laboratory. All individuals sampled were sexed, measured, and separated by cephalothorax length (CC) size classes. Hyalella gauchensis Streck & Castiglioni, 2017 was 22.7 times more frequent and showed significantly greater mean cephalothorax when compared to Hyalella longipropodus Limberger, Graichen & Castiglioni, 2021. Males had a larger body size (CC) than females, although they occur in smaller numbers in both species. The total frequency distribution in CC size classes was bimodal in males and juveniles, and polimodal in females of H. gauchensis. In H. longipropodus the distribution as bimodal in males, females and juveniles. Both H. gauchensis and H. longipropodus had their breeding season and recruitment during the colder seasons of the year (fall and winter, respectively). However, there was a seasonal temporal separation of the intensity peaks between the two species, which could indicate different strategies and/or evolutionary adaptations for their coexistence.
Interseccionalidade: proposta de um mapa teórico provisório
Authors: Kyrillos Gabriela M.
Published: June 2024

Resumo: Este artigo é resultado do esforço de construção de um mapa teórico para compreender e aprofundar os significados da interseccionalidade. No texto há uma revisão de literatura e ele está estruturado a partir de três elementos fundamentais: (1) a história anterior ao surgimento do conceito, (2) algumas formas complexas de entendimento do que é a interseccionalidade, e (3) a justiça social como elemento fundante e inegociável de qualquer estratégia que surja a partir da interseccionalidade. Trata-se de um mapa provisório, localizado e aberto, que pretende se somar a outras concepções particulares de interseccionalidade e contribuir na construção coletiva de seu significado, criticando seus usos como um modismo acadêmico ou esvaziado de seu compromisso político emancipador.
Donna Haraway e a implosão do projeto moderno de ciência
Authors: Soares Maria Helena Silva
Published: June 2024

Resumo: No presente trabalho, nos dedicamos a analisar, a partir do tecnofeminismo de Donna Haraway, sua leitura crítica da construção do projeto moderno de ciência, fundado na separação entre natureza e cultura. Para entendê-la, analisaremos três textos escritos entre as décadas de 1980 e 1990: “O Manifesto Ciborgue”, “Saberes Localizados” e Modest Witness. Seu conceito de ciborgue e identidades fraturadas, e sua crítica à construção da figura do cientista como sujeito de “lugar nenhum” e, por isso, único capaz de dar testemunho válido e fiável, exploram a impossibilidade de um sistema que tende à implosão. Se não há objetividade científica que não esteja implicada em uma localização, o cientista ou a “testemunha modesta” é corporificada e seu olhar, como o de todo e qualquer, bem como sua produção, é sempre parcial.

ABSTRACT Cowpea is the third most cultivated legume in the world, and its cultivation can be intended for both grains and seeds. Plants intended for seed production, when exposed to water deficit, may compromise their physical and physiological quality, necessitating the development of strategies to minimize their damage, such as the application of salicylic acid and HumigelPlus® polymer. The objective of this study was to evaluate salicylic acid and HumigelPlus® polymer concentrations to reduce the effects of water deficit on the physical and physiological quality of cowpea seeds. The landrace cowpea seeds used in this study were sourced from two field experiments (Summer and spring). The treatments consisted of five concentrations of salicylic acid (0, 0.29, 1, 1.71, and 2 mM) and five concentrations of HumigelPlus® polymer (0, 0.29, 1, 1.71, and 2%) combined according to the Central Composite Design and a control group (absence of water deficit and application of salicylic acid and HumigelPlus® polymer). The values of electrical conductivity, germination, emergence, weight, and water content of cowpea seeds were higher with the application of salicylic acid (mM) and HumigelPlus® polymer (%) concentrations between 0.29 and 2, regardless of the season. The application of salicylic acid (mM) and HumigelPlus® polymer (%) concentrations between 0.29 and 2, both in summer and spring cultivation, reduces the effects of water deficit on the physical and physiological quality of cowpea seeds.

ABSTRACT The coconut mite (Aceria guerreronis - Eriophyidae) attacks coconut fruits, inhabits the meristematic region, and causes losses in fruit production. Chemicals are the main control measures but successive applications can cause resistance in mites. In this sense, it is necessary to search for ecological alternatives that assist in sustainable management, as consumers seek products grown using more eco-friendly techniques. This study aimed to identify an entomopathogenic fungal isolate and evaluate its ability to control the mite A. guerreronis, which is present in commercial areas in the municipality of Santa Izabel do Pará, Brazil, in the Eastern Amazon. The efficiency of fungi on mites was tested using six treatments: water (control), chemical acaricide, and fungi of the genera Purpureocillium, Metarhizium, Beuaveria, and Trichoderma; the treatments were applied to the bunches at a concentration of 108 conidia mL-1. The results demonstrated a reduction in mites on fruits, with the B. bassiana and P. lilacinum treatments being the most successful. This study demonstrates that these fungi have acaricidal action and may present an economically viable and ecological alternative for controlling phytophagous mites in coconut cultivation in the Amazon.
Incidência de tuberculose no Brasil: análise de série temporal entre 2001 e 2021 e projeção até 2030

RESUMO Objetivo: Avaliar a incidência de tuberculose no Brasil entre 2001 e 2022 e estimar a previsão de incidência mensal até 2030. Métodos: Trata-se de estudo de série temporal que partiu de registros mensais de tuberculose do Sistema de Informação de Agravos de Notificação e projeções oficiais da população brasileira. Avaliou-se a incidência mensal de tuberculose entre 2001 e 2022 por meio de regressão linear segmentada para identificar quebras de tendências. Utilizou-se o modelo autorregressivo integrado de médias móveis sazonais (Sarima) para prever a incidência mensal de 2023 a 2030, prazo para alcançar os objetivos de desenvolvimento sustentável (ODS). Resultados: Observou-se diminuição da incidência entre janeiro/2001 e dezembro/2014 (de 4,60 para 3,19 casos-mês/100 mil habitantes; β=-0,005; p<0,001), seguida de aumento entre janeiro/2015 e março/2020 (β=0,013; p<0,001). Houve queda abrupta de casos em abril/2020, com início da pandemia e aceleração do aumento de casos desde então (β=0,025; p<0,001). Projetaram-se 124.245 casos de tuberculose em 2030, com incidência estimada em 4,64 casos-mês/100 mil habitantes, patamares da década de 2000. O modelo Sarima mostrou-se robusto, com erro de 4,1% ao remover o período pandêmico. Conclusão: A tendência decrescente nos casos de tuberculose foi revertida a partir de 2015, período de crises econômicas, e foi também impactada pela pandemia quando houve redução nos registros. O modelo Sarima pode ser uma ferramenta de previsão útil para a vigilância epidemiológica. Maiores investimentos na prevenção e controle precisam ser aportados para reduzir a ocorrência de tuberculose, em linha com os ODS.

Para o cálculo de tendência, utilizou-se a regressão de Prais-Winsten e, para a análise espacial, adotou-se o índice global e local de Moran. Resultados: Foram notificados 5.542 casos de estupro pelo parceiro íntimo. As taxas perpetradas pelo cônjuge variaram de 0,34/100 mil mulheres em 2013 para 0,51/100 mil em 2017, com maiores elevações entre 2018 (1,04/100 mil) e 2022 (1,28/100 mil). Houve tendência de aumento no Nordeste como um todo (VPA=19,47; IC95% 15,88–23,22) e em quase todos os estados, exceto Paraíba e Sergipe. Os casos perpetrados por namorados (VPA=23,90; IC95% 12,80–36,09) e entre mulheres de 15 a 19 anos (VPA=22,63; IC95% 4,18–44,35) exibiram maior variação anual. Observou-se concentração de altas taxas em diversos municípios no noroeste do Ceará e no sudeste de Pernambuco. Conclusão: A tendência das taxas de estupro contra mulheres perpetrado pelo parceiro íntimo aumentou no Nordeste, principalmente entre as mais jovens e por namorados, tendo maior aglomerado de notificações no Ceará e em Pernambuco.

RESUMO Objetivo: Analisar a dinâmica epidemiológica espaçotemporal das meningites no Brasil, entre os anos de 2010 e 2019. Métodos: Estudo ecológico descritivo com os casos e óbitos por meningites no Brasil (2010–2019) no Sistema de Informações de Agravos de Notificação. Realizaram-se (I) análises de frequências dos casos e óbitos, taxas de prevalência, mortalidade, letalidade, testes de exato de Fisher e qui-quadrado; (II) regressão de Prais-Winsten; e (III) índice de Moran global, local e densidade de Kernel. Resultados: Notificaram-se 182.126 casos de meningites no Brasil, dos quais 16.866 (9,26%) evoluíram para óbito, com taxas de prevalência de 9,03/100.000/habitantes, mortalidade de 0,84/100.000/habitantes e letalidade de 9,26%. Destaca-se a tendência de decrescimento das taxas de prevalência (−9,5%, intervalo de confiança de 95% — IC95% −13,92; −4,96, p<0,01) e mortalidade (−11,74%, IC95% −13,92; −9,48, p<01,01), enquanto a letalidade se manteve estacionária (−2,08%, IC95% −4,9; 0,8; p<0,1941). A maioria dos casos foi de meningites virais (45,7%), entre 1 e 9 anos (32,2%), enquanto a maior parcela dos óbitos foi por meningites bacterianas (68%), entre 40 e 59 anos (26,3%). Nos mapas de Moran e Kernel das taxas de prevalência e mortalidade, destacaram-se com altas taxas os municípios do sul, sudeste e a capital de Pernambuco, no nordeste; já na letalidade, evidenciaram-se o norte, o nordeste e o litoral do sudeste. Conclusão: Encontrou-se decréscimo dos casos e óbitos por meningites neste estudo, entretanto a taxa de letalidade foi maior em áreas com menor prevalência, reforçando a necessidade do aprimoramento das ações de identificação, vigilância e assistência em saúde dos casos, bem como da ampliação da cobertura vacinal.

ABSTRACT Weeds are responsible for large losses in grain quality and quantity of beans produced. Therefore, studies on competition between beans and weeds are important to achieve more efficient crop management while reducing the use of herbicides. Thus, the aim of this work was to evaluate the competitive ability of bean cultivars (BRS Estilo, IPR Urutau, IAC 1850 and IPR Tangará) in the presence of hairy fleabane (Conyza bonariensis) with different proportions of plants in the association. The experiments were conducted in a greenhouse in a randomized block design with four replicates. The treatments were arranged in different proportions of common bean and hairy fleabane plants: 20:00, 15:5, 10:10, 5:15, and 0:20 plants pot-1. The competitive ability of the species was analyzed using diagrams applied in substitution experiments and relative competitive ability indices. Plant height, stem diameter, leaf area, gas exchange and shoot dry matter were measured 40 days after plant emergence. Negative effects were observed for both the crop and hairy fleabane, as both species competed for the same resources available in the environment. Interspecific competition caused greater damage to plant height, stem diameter, leaf area and dry matter of the species than intraspecific competition. Common bean achieved higher photosynthetic rates and water use efficiency in the presence of hairy fleabane. Common bean cultivars have a greater competitive ability against hairy fleabane.

ABSTRACT The objective of this study was to assess the genetic variability of 63 garlic accessions grown in two environments in the state of São Paulo, Brazil. A randomized block design with replications was used. Agromorphological evaluations were conducted based on descriptors defined by the International Plant Genetic Resources Institute (IPGRI), currently Bioversity International, encompassing 18 characteristics. The obtained data consisted of the mode of each variable and genetic distances from the complement arithmetic of the Jaccard coefficient. Cluster analysis was carried out using Tocher optimization and UPGMA methods; Mantel test was used to assess the correlation of genetic distances between locations. Garlic accessions exhibited genetic diversity for the studied qualitative variables. Correlations between distances of the evaluated accessions were found in both locations, although of low magnitude. Garlic characteristics vary according to growth environment, indicating divergence among accessions. This may be attributed to the plasticity of the species and genotype-environment interaction factors. Phenotypic variability of garlic germplasm observed in a particular environment cannot be extrapolated to other locations.

ABSTRACT The Semiarid region in the Northeast of Brazil is characterized by Caatinga tropical forests, adapted to 8-to-9 months of annual water stress. Human activities have resulted in environmental degradation due to tree removal and soil exposure to erosion factors; however, planting native trees, such as Mimosa tenuiflora and Cnidoscolus quercifolius, may accelerate environmental recovery. Tree recovery was evaluated in a degraded areas under a 14-year period of grazing exclusion (2005 to 2019) and planting of M. tenuiflora (2005 and 2009) and C. quercifolius (2007 and 2009) and under natural regeneration. Data on survival, height, and diameter of planted seedlings, and the number, species, height, and diameter of naturally regenerating trees were collected. The absence of grazing allowed for the establishment of 50.5% and 44.6% of the 204 M. tenuiflora and 204 C. quercifolius planted seedlings, which presented mean heights of 395 and 355 cm and mean basal diameters of 92 and 76 mm. Naturally regenerated M. tenuiflora and C. quercifolius totaled 190 and 7 plants, with heights of 95 and 139 cm, and basal diameters of 10 and 26 mm. A naturally established specimen of Cenostigma pyramidale with a height of 175 cm and basal diameter of 36 mm was found. This denotes the positive effect of seedling planting on tree cove compared to a nearby continuously grazed area; however, full recovery, especially regarding diversity of the tree community, requires more than 14year grazing exclusion, tree planting, and natural regeneration.

ABSTRACT In arid and semi-arid regions, agricultural production is challenging due to the scarcity of water for irrigation, so brackish water is commonly used. However, the use of these waters negatively affects the growth and development of crops. In this context, it is essential to look for strategies to mitigate the effects of salt stress on plants. The objective of this study was to evaluate the effects of foliar application of H2O2 on gas exchange, photosynthetic pigments, photochemical efficiency, and growth of cherry tomato plants in hydroponic cultivation with saline nutrient solution. The experiment was carried out in a greenhouse in Pombal-PB, using a Nutrient Film Technique (NFT) hydroponic system. Treatments were distributed in a split-plot scheme, in which the levels of electrical conductivity of the nutrient solution - ECns (2.1, 2.8, 3.5, and 4.2 dS m-1) were considered the plots and the five concentrations of H2O2 (0, 12, 24, 36, and 48 μM) were considered the subplots, with six replicates and two plants per plot. ECns from 2.1 dS m-1 reduced gas exchange, photochemical efficiency, photosynthetic pigments, relative water content, and growth of cherry tomato. H2O2 at concentrations of 36 and 48 μM associated with saline nutrient solution of 2.1 dS m-1 stimulated plant height, growth, and chlorophyll b synthesis, respectively. Hydrogen peroxide alone did not affect gas exchange, chlorophyll fluorescence, photosynthetic pigments, and growth of cherry tomato.

ABSTRACT The objective of this study was to evaluate the effect of foliar application of salicylic acid on the physiological indices and growth of Japanese cucumber cv. Hiroshi grown under saline nutrient solutions in a hydroponic system. The experiment was conducted in a greenhouse at the Center of Science and Agri-Food Technology of the Federal University of Campina Grande, Pombal, PB, Brazil, using the Nutrient Film Technique (NFT) hydroponic cultivation system. A completely randomized design was used in a split-plot scheme, with plots consisting of four levels of electrical conductivity of the nutrient solution - ECns (2.1, 3.6, 5.1, and 6.6 dS m-1) and subplots consisting of concentrations of salicylic acid - SA (0, 1.8, 3.6, and 5.4 mM), with four replicates and two plants per plot. ECns of 4.8 dS m-1 associated with foliar application of 3.6 mM of SA resulted in higher relative water content. Growth, photosynthetic pigment synthesis, and biomass accumulation in Japanese cucumber plants are inhibited by nutrient solution from 2.1 dS m-1. Salicylic acid at concentration of 2.0 mM promoted a higher relative growth rate of leaf area for plants under nutrient solution of 2.1 dS m-1. SA concentration of 5.4 mM associated with saline nutrient solution of 6.6 dS m-1 resulted in a higher root/shoot ratio, but intensified the deleterious effects of salt stress on the biomass accumulation of cucumber plants.

ABSTRACT Mining in the municipality of Capitão Poço, Pará, has resulted in soil degradation as the main consequence. Therefore, this study aimed to evaluate the stocks of the elements (N, P, K+, Na+, Ca2+, Mg2+, Fe, Zn, Cu, and Mn) in roots in areas of post-pebble mining recovery in Pará, Brazil. The study was carried out in four areas, namely the area under recovery with soil bioengineering techniques (complementary construction technique and soil stabilization technique), the area under recovery with a natural regeneration process, the degraded area, and the native forest located in the municipality of Capitão Poço-PA. Roots were collected at 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-80, and 80-100 cm soil layers, quantified the dry biomass and contents of macro and micronutrients, and then, estimated the stocks of elements in roots. The data of the element stocks in roots were subjected to the Shapiro-Wilk normality tests and analysis of variance. Means were compared using the Tukey test at 5% significance using the SISVAR statistical software. The highest average Na+, Ca2+, and Mg2+ values in fine roots were in areas with bioengineering and native forest. The native forest presented the highest average values of macro and micronutrients in fine and thick roots. Furthermore, the lowest stocks of elements in roots were in the degraded area. However, bioengineering techniques are effective in recovering degraded soils, as vegetation cover reestablishes the balance of the soil-plant system.

ABSTRACT Proper salinity concentration can positively impact the growth of sunflower plants. From this perspective, this study aimed to evaluate the sunflower BRS 323 with regard to the effects of salinity and the use of pyroligneous solution as a salt stress mitigator. The experiment was conducted in a plant nursery. The experimental design was completely randomized, in 5 x 2 factorial arrangement with four replications, with one plant per plot. The treatments corresponded to five electrical conductivity levels of irrigation water: 0.75 dS m-1 (control); 1.65; 1.95; 2.65 and 2.85 dS m-1, obtained by dissolving sodium chloride, and two conditions of pyroligneous solution application , with and without. Weekly, the plants were evaluated for growth in height, diameter, and leaf area. Also, the values of the indices of chlorophyll a, chlorophyll b, total chlorophyll, shoot and root fresh and dry mass, and flower bud fresh and dry mass were evaluated 50 days after sowing, corresponding to the end of the experimental phase. The results suggest that the pyroligneous solution, at the concentration tested, can be recommended to increase the levels of chlorophyll a, chlorophyll b and total chlorophyll. Moderate salt stress of 1.65 dS m-1 promoted an increase in the growth parameters of sunflower plants.
