Abstract This study aimed to investigate the association between maxillary sinus reactions and periradicular pathology in maxillary posterior teeth using cone-beam computed tomography. The maxillary posterior images of 395 teeth were examined for the presence of periradicular pathology, and the maxillary sinus disease. The proximity between the root apex and the cortical bone of the maxillary sinus using the linear measurement (mm) tool was used (RadiAnt, DICOM viewer, Poznan, Poland). The frequency found from maxillary sinus assessment was subjected to the Kolmogorov-Smirnov normality test, the Kruskal-Wallis test, the chi-square test with Bonferroni correction and a logistic regression analysis. A significance level of 5% was assumed. About 46.6% of the teeth showed a periapical pathology associated with an inflammatory reaction of the maxillary sinus. Among them, thickening of the maxillary sinus mucosa > 3 mm is the most common finding (59.3%). There was no difference between the types of maxillary sinus reactions and the variables studied (p >0.05). Periapical lesions on palatal roots were 2.17 times more likely to develop an inflammatory reaction than other roots (p < 0.05). Women were 2.04 times less likely to develop maxillary changes than men (p < 0.05). The distance between apex and floor and the presence or absence of endodontic treatment were not significantly associated with sinusitis. Periapical pathology could be related to maxillary inflammatory reaction of the sinus.

Published: December 2024

Abstract The aim was to estimate the cost-effectiveness and cost-benefit of CWF for schoolchildren according to different population sizes served in Brazil. The economic evaluation was conducted from a societal perspective. Total costs were estimated using four variables across different population sizes: capital cost of initial installation, chemical product costs, system operational costs, and monitoring costs. The effect of CWF was analyzed in the context of the widespread use of fluoridated toothpaste, based on studies with Brazilian population groups. The total cost of dental treatment was estimated, including both direct and indirect costs, with a discount rate of 3.5%. A one-way sensitivity analysis was conducted to test the robustness of the results based on measured parameter values. The costs averted due to CWF were US$174.40 and US$85.67 for children aged 5-8 and 3-12 years, respectively, and US$46.66 for those aged 7-12 years, according to the average effectiveness of CWF for each age group. The cost-effectiveness and cost-benefit ratio results were favorable in all scenarios where the population served was 6,000 or more inhabitants. Scenarios unfavorable to CWF were observed only in populations of up to 2,000 inhabitants. The economic evaluation of CWF in an upper-middle-income country proved to be a cost-effective oral health intervention and more economically advantageous, especially in larger areas for both deciduous and permanent dentition.

Resumo Introdução A depressão e o risco de suicídio constituem graves preocupações de saúde mental que afetam de forma intensa populações vulneráveis, como as comunidades quilombolas. Embora a prática de atividade física seja amplamente reconhecida por seus benefícios na prevenção e manejo da depressão, ainda são escassos os estudos que abordem de maneira específica as particularidades dessa população. Objetivo O objetivo deste estudo é analisar a associação do transtorno depressivo maior (TDM) e risco de suicídio (RS) com a prática de atividade física de mulheres quilombolas. Método Trata-se de um estudo transversal, de abordagem domiciliar, em comunidades quilombolas no Rio Grande do Sul. A presença atual de TDM e RS foi verificada através do instrumento International Neuropsychiatric Interview (MINI). A prática de atividades física foi obtida pelo International Physical Activity Questionnaire (IPAQ). Resultados Participaram do estudo 178 mulheres quilombolas, das quais 14,6% foram diagnosticadas com depressão e 23,0% apresentaram risco de suicídio. As mulheres que apresentaram depressão com risco de suicídio tinham tempo de atividade física significativamente menor em relação às mulheres que não apresentaram tais diagnósticos. Na análise multivariada, a inatividade física continuou associada à depressão (RP 1.90 IC95% 1.13-3.21) e ao risco de suicídio (RP 1,92 IC95% 1.03-3.57). Conclusão O presente estudo evidencia maior prevalência de indicadores de depressão e risco de suicídio para as mulheres inativas. A inclusão de estratégias de atividade física pode contribuir para reduzir a vulnerabilidade, reduzir os sintomas depressivos e prevenir a carga de suicídio entre as mulheres quilombolas.

RESUMO O presente estudo desenvolveu uma nova metodologia de processamento termomecânico, que consiste na combinação de técnicas de deformação plástica severa e tratamento térmico de reversão martensítica. Com o propósito de refinar a microestrutura de um aço inoxidável AISI 201 LN e obter um material com propriedades avançadas. Para isso, o material foi solubilizado a 1050 °C por 1 hora. Em seguida o aço foi deformado via extrusão em canal angular (ECAP) a 300 °C por 3 passes utilizando a rota BC, com intuito de reduzir o tamanho de grão (TG) e ao mesmo tempo aumentar a dureza do material, sem que ocorra a transformação martensítica. Posteriormente, o mesmo foi submetido ao forjamento rotativo, com 35% de redução do diâmetro, com intenção induzir a transformação martensítica e consequentemente o aumento da dureza. Por fim, o material foi tratado termicamente para reversão da martensita, a 750 °C por 15 minutos. Os resultados evidenciaram que não ocorreu transformação de fases no material submetido ao processo de ECAP, entretanto ocorreu um aumento significativo na dureza (cerca de 80%) no terceiro passe e uma redução do tamanho de grão. O forjamento rotativo promoveu a transformação martensítica e por consequência elevou em cerca de 170% a dureza. Após o tratamento de reversão, foi observado, pelas imagens de EBSD (Electron Backscatter Diffraction – Difração de elétrons retroespalhados) redução e a maior homogeneização do tamanho de grão, além do aumento na dureza do material quando comparado à condição de como recebido. As curvas de tração evidenciaram o aumento significativo no limite de escoamento e na tensão de ruptura do material.

Published: December 2024

Abstract Sesbania javanica Miq. is widely distributed in canals throughout Thailand and its flowers are commonly consumed in Thailand. Sesbania javanica floral extracts have previously been demonstrated to have antimutagenic activity, but information on the bioactivity and beneficial properties of other plant parts, such as the leaf, remains limited. In this study, the induction of cell proliferation and wound-healing activity of DMSO extracts from flowers and leaves of S. javanica was evaluated. A high concentration (1:25 and 1:50 dilutions) of all extracts was cytotoxic to Balb/c 3T3 fibroblast cells. A low concentration (1:500 and 1:1000 dilutions) of extracts A, B, and C (extracted from leaves) significantly promoted cell viability after treatment of the fibroblast cells for 24 or 48 h. The 1:500 and 1:1000 dilutions of extracts B and C were selected for a scratch assay to assess their wound-healing activity and significantly decreased the wound area after treatment for 24 h. These findings provide evidence that leaf extracts from S. javanica have potential utility for the treatment of wounds.

Authors: Dias Amanda Martins , Feitosa Rodrigo Machado
Published: December 2024

Abstract: The Parque Nacional da Serra do Divisor (PNSD), renowned for its remarkable biodiversity, is a conservation unit of the Amazon biome situated at the westernmost limit of the Brazilian territory. However, the PNSD fauna is still poorly documented for most taxa. This study aimed to list the ant species (Hymenoptera: Formicidae) of the PNSD, comparing its diversity found with studies conducted in other hotspots of biodiversity of the world. Field collections were conducted in the northern region of PNSD for four days in 2016, using three collection methods: epigaeic pitfall traps, Winkler extractors, and hand collections. Even with the short sampling period, an impressive number of 261 species of ants were recorded, representing one of the highest richness documented for ants with the least sampling effort applied in a single locality worldwide. Of these species, 66 were newly recorded in the state of Acre, with six representing first-time records for Brazil. These findings highlight the critical importance of the PNSD as a strategic area for ant conservation, both in Brazil and globally.

Published: December 2024

Abstract: The program “REFLORA - Brazilian Plants: Historic Rescue and Virtual Herbarium for Knowledge and Conservation of the Brazilian Flora” was established by the National Council for Scientific and Technological Development (CNPq) in 2010, involved numerous participants at the international, federal, state, and private company levels, and included approximately 24.5 million reais in investments over a period of 5 years. It had the objective of rescuing and making available images and information about herbarium specimens of Brazilian plants deposited in foreign collections. Under the auspices of this program, research projects were financed with consumable, durable, and grant resources that covered aspects of taxonomy, evolution and phytogeographic adaptation, molecular biology, conservation, use, and historical details of expeditions and their relationship to the colonization of Brazil. Additionally, using subsidies from the REFLORA Program, the REFLORA Virtual Herbarium was created allowing the program to fulfill its initial objectives of receiving 500 thousand images and repatriating data from the RBG-Kew and MNHN-Paris herbaria, as well as data and images from other national and foreign herbaria that were subsequently added. This article describes the historical context of creating and implementing the REFLORA Virtual Herbarium, which has become one of the most important tools for research and advancing knowledge about the biodiversity of plants and fungi, in addition to being fundamental to fulfill international goals and agreements assumed by Brazil, such as Flora of Brazil 2020.

ABSTRACT: Standardizing trimming the brain for histological diagnosis of neurological diseases is challenging for veterinary pathologists. The striatum is a set of subcortical nuclei of the forebrain, formed by bundles of nerve fibers and gray matter, which consist of the internal and external capsules, caudate, lentiform, and claustrum nuclei. The striatum is related to motricity, which refers to the neural circuits of the extrapyramidal pathways. In domestic animals, the extrapyramidal pathways are of great importance in gait. From the ventral surface of the brain, they are located deep in a strip of the telencephalon corresponding to the olfactory trigone. Bovine and equine brains were routinely formalin-fixed, weighed and measured. Herein, we report a guide for bovine and equine brains’ neuroanatomic trimming and striatum histomorphology. Trimming was performed, and the sections were routinely processed for histology. We used the cross-section rostral to the optic chiasm as the site of choice for histologic sampling to identify the striatum structures. The forebrains were sectioned, and the standard histologic cassette was positioned horizontally or vertically to frame a greater diversity of structures. The histologic slides were labeled with structures of the striatum (caudate nucleus, internal capsule, lentiform nucleus, external capsule and claustrum). Regarding the brain size, handing the cassette orientation over to the forebrain allows the verification to shift the position or collect a second striatum sample for histology.

ABSTRACT: Companion, livestock, and wild animals have various biological, behavioral, and ecological differences that may lead to distinct pathological conditions. Moreover, unlike human medicine, there is no standardized code for classifying diseases in animals, resulting in varied presentations of findings across studies. Standardizing these data can help clinicians identify diseases and facilitate communication among veterinarians. A systematic review of the literature was conducted across five databases to identify the main causes of animal death in the domains “companion”, “livestock”, and “wild” animals. The analysis included the 31 articles provided in the evidence summary section. Subsequently, the causes of death were classified according to the International Classification of Diseases, tenth revision (ICD-10) and analyzed according to the presence of Garbage Codes. There was considerable diversity in the causes of death and how they were assessed and reported in each domain. Each species and domain demonstrated a high proportional mortality of causes uncommon in other domains. The companion domain included seven articles, livestock had nine articles, and wild animals had fifteen articles with 66.85%, 71.43 %, and 20.06% Garbage Codes, respectively. The different causes of death and their descriptions indicate a low level of uniformization in the presentation of findings in veterinary medicine. The causes varied based on the domains and species investigated, highlighting real distinctions between these populations. The application of ICD-10 for standardizing the diagnosis of animal mortality proved useful in detecting highly prevalent Garbage Codes.

Published: December 2024

Resumo A pesquisa caracteriza o modo de organização de três expressões da Agricultura Urbana (AU) calcada na tipologia estabelecida por Feniman (2014): Assistida, Vernacular e Politizada. Metodologicamente adotou-se uma estratégia de pesquisa de casos de base qualitativa e natureza descritivo-exploratória, contemplando a coleta de dados e posterior análise comparativa das organizações. Os resultados apontam que o modo de organização da Assistida é de base técnica instrumental, dependente da assistência do poder público, com favorecimento da produção de espécies com valor de mercado e estruturação social formalizada que limita integração social interna e externa, além de apresentar menor utilização de tecnologias de produção não convencionais. A Organização Vernacular tem base de estruturação informal e afetiva, que valoriza saberes ancestrais e a manutenção de práticas tradicionais, estando fixada em forte enlace familiar. A Organização Politizada manifesta o desejo dos participantes em conferir à agricultura urbana um aspecto integrativo, alternativo, soberano, autônomo e inovador, embora apresente limitações no que diz respeito à constituição de uma vida comunitária estável. O estudo demonstra que os modos de organização observados se relacionam com diferentes dinâmicas de ocupação do espaço, participação, estruturação social, uso de tecnologias de produção, relações com poder público e inovação social.
Enhancing crop insurance analysis with agricultural zoning data
Authors: Martins Gilson , Signorini Guilherme
Published: December 2024

Abstract This article proposes a framework for integrating agricultural zoning data into insurance risk analysis. It is based on combining official public information from the Brazilian zoning program, ZARC, with open insurance data provided by the Brazilian Ministry of Agriculture and Livestock. The methodology presented in this article transforms ZARC information into distributional data and integrates it into a Bayesian model alongside insurance indemnities data, allowing for comprehensive risk analysis. It uses information on soil types from ZARC to develop basic best- and worst-case scenarios and calculate posterior distributions using insurance data. The resulting framework enables the comparison of municipalities, crop types, and overall risk classification. The study applies the framework to analyze the risk of soybeans, corn, wheat, and corn double-crop in Paraná State, resulting in consistent risk classifications across all crops and municipalities. The proposed framework has the potential to enhance agricultural risk management analysis for reinsurers, insurers, government agencies, and private companies. Future research could explore the use of this methodology to compare insurers, analyze risk in structured operations of credit and insurance, and evaluate risks at the farm level. This article presents a potential tool for improving risk analysis and decision-making in the agricultural sector.
Discourse communities on archival education and research: a domain analysis of the Archival Education and Research Initiative - AERI (2008-2021)

Published: December 2024

Abstract In the international context, the discourse community Archival Education Research Initiative, made up of faculty members and students in the field of archives, works with a focus on the educational and research dimension, guiding the debate on historically marginalized communities and how they are (under)represented in archives. Considering that this debate has also been taking place in the Brazilian context in recent years, this paper aims to characterize this discursive community based on its actors and their scientific productions. The methodology employed is exploratory and descriptive. Domain Analysis was used through two lenses: (a) epistemic, focusing on the biography of the community members, and (b) scientific production, focusing on the publications of its members in the period 2008-2021. The results were systematized along two axes: the epistemic profile, which is a biographical aspect, and the scientific structure profile. The members’ biographies cover two dimensions: research dealing with community archives, human rights, critical theory, social justice, and post-colonialism, and research dealing with archival dimensions concerning information and communication technologies and knowledge organization.
Some core concepts of domain analysis
Authors: Hjørland Birger
Published: December 2024

Abstract This article claims that information systems should provide reliable and trustworthy information, and that this demand imply a re-orientation of information science with knowledge organization from, for example, approaches based on studies of user’s preferences, towards studies of quality and the values and goals in the documents being mediated. This mediation is done by information professionals in their knowledge organization systems and -processes. For this purposes, the philosophy of science becomes an important subject, which has implications for the understanding of a long range of concepts. Here, the following concepts are briefly introduced: “social epistemology”, “information”, “question,” “relevance,” “information need,” “concept,” and “subject” (of documents).

Published: December 2024

ABSTRACT Objective: To assess the pragmatic adequacy of the Interactive Theory of Breastfeeding based on the Fawcett’s Model. Method: Theoretical study, according to evaluation criteria proposed by Fawcett. The six questions suggested in the model were used, answered based on searches in scientific literature, consultation in legislation supporting nursing professional practice and information from the authors of the theory. Results: It was observed that during their training, Nurses acquire skills for care, but clinical management focused on breastfeeding should be emphasized. Since its creation, the theory has been applied in an ascending manner, proving its application in clinical practice to be viable. The existence of laws and resolutions guarantee clinical nurses the legal support necessary to develop a practice based on the Interactive Theory of Breastfeeding. Conclusion: The pragmatic adequacy of the theory was observed, showing that the Interactive Theory of Breastfeeding subsidizes a care directed at the mother and child binomial, supporting the nurse in their decision-making, contributing to the protection, promotion, and support of breastfeeding.

ABSTRACT Objective: To analyze nursing mothers’ social representations of sexuality in the breastfeeding context and their repercussions in sexual and reproductive health. Method: An exploratory study grounded on the Theory of Social Representations and conducted in a Human Milk Bank from northern Brazil with 110 nursing mothers, following the Free Word Association Technique. Data were analyzed by means of Correspondence Factor Analysis in the software Tri- Deux-Mots 5.1. Results: Sexual intercourse was the significant expression of sexualities, reflected in the representation of this phenomenon in breastfeeding, anchored in cultural gender relations; meanwhile, the search for sexual desire and pleasure connected to the ideal of romantic love arises. The bodily and daily changes inherent to this period take on an unfavorable connotation and become naturalized over time, negatively influencing nursing mothers’ sexual and reproductive health. Conclusion: Understanding sexuality/sexualities in the breastfeeding context can support Nursing and Health care models in line with the social experiences and thoughts of the different groups of nursing mothers.

Published: December 2024

ABSTRACT. Aging is generally associated with a decline in cognition when compared to adulthood. The changes most seen are in attention, perception, working memory, short-term memory, free recall, and processing speed. Certain changes in the Judgment of Line Orientation (JLO) test may be present in elderly people. Objective: The objective of this study was to describe the difference among age, sex, schooling, Mini-Mental State (MMS), and Mini-Mental State Examination (MMSE) when compared to the JLO test in elderly people. The second is to assess the clinical use of the JLO test in elderly people's cognitive decline in Northeast Brazil. Methods: A cross-sectional, randomized study was carried out on 280 elderly people, between 60 and 89 years old, and the mean age was 69.4 (±6.8 years SD); 73.9% of the females lived in Olinda City, State of Pernambuco, Brazil. Age was stratified every 5 years between 60 and 89 years old, and schooling was divided into four subgroups between illiterate and more than 8 years of schooling. Each participant was submitted to an analysis of age, sex, schooling, risk factors, MMS, modified MMSE, and a JLO test. Results: There was no statistical difference between the sexes. However, there was a statistical difference when compared to the JLO test and age (p<0.012), schooling (p<0.001), MMS (p<0.001), and modified MMSE (p<0.001). Conclusion: We observed that with a cutoff point of 18 points, the JLO test is indicated to assess visuospatial and visuoperceptive changes in elderly people in Northeast Brazil.

Authors: Bodart Cristiano das Neves
Published: December 2024

Abstract This article presents an analysis of co-authorship networks among Sociology Teaching researcher, with the purpose of examining the constituent aspects of the research subfield. By using the method of production and analysis of co-authorship networks in academic papers published in the last 10 years, we identified micronetwork formations and their main social agents of connection. The results reveal the presence of interconnected micronetworks that form a broader network of researchers, some of them dynamizers and aggregators of this social sphere. In addition, we note the relevance of universities and other instances of collaboration, especially political spaces of struggle for the maintenance and qualification of the Sociology teaching. This imbrication between the Sociology Teaching research subfield and a larger sphere, called by researchers as the “Sociology Teaching field,” is evidenced and analyzed.

Published: December 2024

Abstract This study addresses the historical trajectory of the professional education of magistrates in Brazil, through the perspective of development achieved by magistrate education schools in contemporary justice systems. It is a historical-documentary and bibliographical research that adopted historical-dialectical materialism as its theoretical-methodological grounding. The objective was to analyze the socio-historical context and the rationale for developing this specific type of human education. In the end, we point out that this education is a product of the complexification of social relations and modern constitutionalism, which progressively required the State to take a mediating stance in the face of emerging social contradictions.
Caries disease in childhood cancer patients: a literature review
Authors: Miquelão Julia Pianezzer , Barros Julia Funez , Longo Bruna Cristina
Published: December 2024

ABSTRACT This study aims to present the prevalence of dental caries in childhood cancer patients, emphasizing the effects of antineoplastic therapy. To carry out the study, a search strategy was adopted that covered books from 2017 to 2022 and articles available in databases, published between 1997 and 2021, in English and Portuguese. In recent years, there has been an increase in the incidence of malignant neoplasms in pediatric patients. The most common are leukemias, lymphomas, and tumors of the central and sympathetic nervous systems. The treatment of these diseases is antineoplastic therapy, which aims to combat cancer cells. However, it can cause unwanted effects such as systemic, craniofacial, and dental changes. The most common oral manifestations are caries, microdontia, hypodontia, root changes and taurodontism. The relationship between tooth decay and childhood cancer is still not well understood, as factors such as diet and oral hygiene can play a confounding role in the development of tooth decay. Antineoplastic therapy increases the patient’s risk of developing caries disease, however, it has not yet been proven to be a disease-modifying factor, so additional studies must be carried out.

Resumo A discussão acerca do papel do Estado tem sido habitual em tempos de avanço do processo de globalização. Ao considerar a disseminação das ideias neoliberais e as ações decorrentes destas, cabe atenção sobre as transformações acerca das atribuições do Estado. Dessa maneira, este artigo objetiva examinar o papel do Estado no atual contexto da globalização e a respectiva contribuição com a acumulação por espoliação, no Brasil e no estado do Paraná, especialmente entre os anos de 2003 e 2018. Para isso, o presente estudo identificou algumas ações dos governos federal e paranaense nesse período. Os procedimentos metodológicos adotados foram a revisão bibliográfica e documental, com uso de dados estatísticos. Os resultados evidenciaram que o Estado tem contribuído continuamente com a acumulação por espoliação, especialmente quando governado sob perspectivas neoliberais. Portanto, a ideia do Estado mínimo não encontra lugar nos governos analisados.

ABSTRACT This study aimed to evaluate the competitive interaction between maize hybrids in the presence of Digitaria insularis through experiments in a series of substitutions. The experiments were conducted in a randomized block design with four replicates. Six maize hybrids were used, and the plant density of maize and D. insularis hybrids was set for constant final production of 463 plants m-2. Competition had a detrimental effect on plant growth in both species. Competition and demand for environmental resources were the same for maize hybrids competing with D. insularis. Digitaria insularis had a negative effect on the physiological characteristics of maize hybrids, regardless of the plant density in the association. The hybrids showed greater relative growth than the weed. However, the increase in weed density decreased the nutrient concentration, especially P and K, in maize hybrids. There was competition between maize and D. insularis for the same resources in the environment. Interspecific competition was more pronounced for nutrients N, P, and K, whereas intraspecific competition was more pronounced for Ca and Mg.

ABSTRACT Effects of abiotic stresses, such as high temperature, on plants are exacerbated by climate change. Lima beans exhibit higher tolerance to high temperatures than the common beans. Understanding the tolerance of lima bean landrace germplasm to high temperatures is important to improve their breeding. Therefore, in this study, we aimed to examine the high temperature responses of lima bean landrace varieties obtained from the Phaseolus Germplasm Bank at Universidade Federal do Piauí (BGP-UFPI, Brazil) in two environments. Five landraces showing the best performance in emission of flowers and number of pods formed (UFPI-945, UFPI1037, UFPI-876, UFPI-1036, and UFPI-1064) were evaluated in two cultivation environments, natural (29 ºC) and controlled (37 ºC), using a completely randomized design with four replications, with each plot consisting of a single plant. Analysis of variance and Tukey’s test (P < 0.05) were performed for 12 quantitative traits, followed by Pearson’s correlation analysis. Lima beans exhibited genetic variability in high temperature tolerance in both natural and controlled environments. Specifically, UFPI-1064 exhibited superior performance with higher pod thickness and width and number of flowers and lower flower and pod abortion than the other varieties in both natural and controlled environments. Pearson's correlation analysis revealed positive and strong correlations between the number of flowers and flower abortion in the natural environment and number of pods and seeds per pod in the controlled environment.

ABSTRACT The cultivation of conventional maize in refuge areas is important for preserving Bt technology and serving specific markets with greater added value to the grains. Therefore, research aimed at chemical weed control must also continue to be directed to conventional maize hybrids. The objective was to evaluate the selectivity of herbicides applied in preand post-emergence of a conventional maize hybrid cultivated in the Cerrado biome of Brazil. Two field experiments were set up, one in summer and the other in second season. The treatments were composed of eleven herbicide treatments, whose doses are presented in g ha-1 of active ingredient: S-metolachlor (1,440), S-metolachlor (1,680), mesotrione + atrazine (115.2 + 2,000), mesotrione + atrazine (192 + 2,000), tembotrione + atrazine (75.6 + 2,000), tembotrione + atrazine (100.8 + 2,000), nicosulfuron + atrazine (16 + 2,000), nicosulfuron + atrazine (24 + 2,000), [mesotrione + atrazine] ([120 + 1,200]), sequential application of [mesotrione + atrazine] ([60 + 600]), atrazine (2,000), plus a weeded control. Regardless of the experiment, all herbicides applied preand post-emergence of maize led to low percentages of phytointoxication. In both experiments, none of the treatments caused reductions in crop stand, confirming the absence of plant mortality due to the application of herbicides. Plant tipping/lodging was seen in summer maize, with no treatment effect. Maize 100grain mass and yield did not change as a result of the application of herbicides in preand post-emergence of the crop. All herbicide treatments evaluated showed selectivity for the conventional maize hybrid.

ABSTRACT Soil organic matter is one of the most important indicators of the quality and sustainability of native and cultivated ecosystems, as it influences the chemical and physical properties of the soil, such as cation exchange capacity, aggregation, water retention, and supply of nutrients to plants. This study evaluated the physical properties and distribution of organic carbon in soil aggregates under different management practices. Disturbed and undisturbed soil samples were collected in the 0.0-0.1 m, 0.1-0.2 m, and 0.2-0.3 m layers under conservationist (rainfed and irrigated) and conventional (rainfed) management. The chemical properties and particle size, soil density, and organic carbon content in macro and microaggregates were assessed for the three management types. For conservationist management, in addition to these analyses, the weighted mean diameter, geometric mean diameter, aggregate stability index, and total soil porosity were determined. The data were analyzed using the Kruskal-Wallis test and the t-test, as there was no experimental design, and some of the data did not meet the normality test (Shapiro-Wilk). Soil density and total porosity did not differ for conservationist management (rainfed and irrigated). The irrigated conservationist management exhibited aggregates with larger weighted and geometric mean diameters and a higher aggregate stability index. Conservationist management (rainfed and irrigated) showed higher organic carbon contents in macro and microaggregates.

ABSTRACT Plant growth stimulants are a promising technology for agriculture to improve plant growth. These stimulants are often derived from a blend of plant regulators, minerals, amino acids, and other substances tested on various plants. The objective of this study was to evaluate the effects of a growth stimulant (micronutrients and amino acids) for seed treatment and foliar application on the initial growth of watermelon (Citrullus lanatus; cultivar Crimson Sweet). A randomized block experimental design with four replications was used, in a 6×2 factorial arrangement consisted of six growth stimulant rates (0, 1, 2, 3, 4, and 5 mL kg-1) for seed treatment, combined or not with foliar application of the same growth stimulant at 300 mL ha-1 26 days after sowing. The plant characteristics evaluated were: number of leaves per plant; shoot, root, and total plant lengths (cm); and shoot, root, and total dry weights. The use of the growth stimulant rate of 4 mL kg-1 for treating watermelon seeds, combined with foliar application of the growth stimulant (300 mL ha-1 26 days after sowing), provided the best growth conditions to the plants, which was shown by their higher number of leaves, shoot length, and shoot and total dry weights.

ABSTRACT World demand for wood products and the shortage of good quality lumber species are exerting pressure on native forests. This study aimed to evaluate the efficiency of Eremanthus erythropappus crude oil in improving the resistance of Pinus taeda wood to Rhodonia (≈Postia) placenta, Gloeophyllum trabeum, Neolentinus lepideus (brown rot) and Pycnoporus sanguineus (white rot) in accelerated laboratory decay tests. Test samples measured 1.90 × 1.90 × 1.90 cm. Oil was applied to wood surfaces using a brush to obtain nominal retentions of 15, 30, 45, and 60 kg of oil per m3 of wood. After treatment, the samples reached average retentions of 16.25, 28.75, 41.50, and 53.75 kg m-3, respectively, and were submitted to a soil block decay test (accelerated decay test) for 12 weeks. Increased oil retention caused a decline in the mass loss of Pinus taeda wood exposed to the fungi tested. A retention of 16.25 kg m-3 inhibited Rhodonia placenta degradation and prevented other xylophagous fungi attacks. The most severe decay occurred with Rhodonia placenta and the least with Pycnoporus sanguineus. Oil improved Pinus taeda resistance to the decay fungi, indicating that it is useful for treating wood in contact with domestic animals and humans, since it is not toxic to them.

ABSTRACT Oil-derived compounds present in the soil can compromise plant growth and inhibit the development of the microbial population. These contaminants reduce soil porosity, hinder water absorption, and can disrupt plant metabolic processes. The aim of this research was to evaluate the effects of the presence of three hydrocarbons in the soil on the growth and development of forage species and on soil microbiological indicators. The experiment was carried out in a greenhouse using a randomized block design with four replications. Treatments were arranged in a 5×4 factorial, with the first factor consisting of the species evaluated (Pennisetum glaucum, Zea mays, Brachiaria ruziziensis, Panicum maximum and Sorghum bicolor) and the second factor corresponding to the presence of contaminants: benzene, toluene or xylene and soil without contaminants. The species were grown for 42 days. The tolerance of the species depended on the type of contaminant present in the soil. The total dry matter of P. glaucum was reduced by 26%, 10% and 32% for toluene, benzene and xylene, respectively. Z. mays had its growth reduced in the presence of toluene (13%) and benzene (21%). S. bicolor had its dry matter increased by 58% with xylene. B. ruziziensis and P. maximum were tolerant to all contaminants. The magnitude of the effects of contaminants on soil microbiological indicators depended on the species grown. The tolerance of plants and soil microbial community to contaminants depends on the forage species used and should be an important aspect when selecting plants to restore degraded areas.
