Cassava production in the state of Alagoas is mostly carried out by small rural producers who adopt little management technology, and who routinely do not replace nutrients due to the high cost of chemical inputs. In this agricultural production model, the knowledge and use of strategies that include natural biological processes in the soil, mainly of the microbiota present in this environment, such as arbuscular mycorrhizal fungi (AMF), can be presented as an alternative for biofertilization, since, Arbuscular mycorrhizae are symbiotic associations established between the roots of most plants and non-pathogenic fungi in the soil that have beneficial effects, which can improve plant growth and productivity and soil structure. Thus, the aim of this study was to evaluate the density of glomerospores and the native AMF genera present in the rhizosphere of cassava, Sergipana variety, as well as to determine mycorrhizal colonization in the evaluated culture. Soil collections were made in the cassava rhizosphere, at 90, 180, 270 and 360 days after planting (DAP). The average number of glomerospores in each treatment was evaluated at 90, 180, 270 and 360 DAP, and the main AMF genera present, and an evaluation of mycorrhizal colonization of the roots at 360 DAP was performed. Cassava cultivation showed an increase of approximately 174.46% at 360 DAP, showing a significant difference in the density of AMFs when compared to the 90 DAP period. The genera Diversispora sp, Entrophospora sp, Acaulospora sp, Scutellospora sp, and Racocetra sp. in cultivation, and a positive result for mycorrhizal colonization, with a 61% rate of colonization of the roots of the evaluated species.

ABSTRACT: The Knowledge of the initial diversity of entomofauna in eucalyptus spp forest stands. it can provide an effective characterization of the insect community, evidencing aspects of local diversity, besides contributing to the registration of insect pests with potential for crop damage, biological control agents, pollinators among other organisms and their complex trophic networks. Thus, the study aimed to perform the survey and faunistic analysis of the entomofauna associated with clonal experimental forest settlement of the hybrid Eucalyptus urograndis (clones TP361, VCC865, I144 and VE41), through manual collection in the State of Alagoas. The collections were carried out between January 2018 and January 2019 in six-month-old plots, and the branches of the plants were evaluated, analyzing the presence of individuals. The diversity of entomofauna and faunistic indices were determined using the ANAFAU software. A total of 577 individuals were collected, distributed in 10 orders, and coleoptera orders (30.4%), Hemiptera (23.58%) and Hymenoptera (13.73) the ones that stood out the most for the greater number of captured individuals. The Chrysomelidae family presented expressive indexes for all clones evaluated, due to a population outbreak of C. ferruginea in the study area. Clone I144 presented higher diversity value of Shannon-Weaner (H') (2.7) when compared to the other clones, TP361 (2.6), VE41 (2.5) and clone VCC865 (2.4), which presented lower diversity index.

Experimental activities can be considered didactic tools to strengthen science teaching. Therefore, this teaching research carried out in the education laboratory of the Escola Estadual Senador Rui Palmeira - PREMEM, shows that in order to achieve the main objectives of science education, it is necessary that this practice be redefined or repositioned. The aim of this work was to analyze the level of understanding of chemistry content through applied practice with contextualization in everyday life, conceptualizing the importance of practical classes for teaching chemistry. It is a research through the execution and application of experimental classes, during the year 2018 to 2020 in the elective discipline of Experimental Chemistry for the 1st, 2nd and 3rd year grades of PREMEM high School. The relationship between achievement and learning by the student was evaluated and the challenges related to experimentation classes in the teaching of chemistry were analyzed. It was observed a good use and learning on the part of the stressing that the experimentation is a very important tool to improve the rates of achievement and learning. In addition, it is necessary for the teacher to plan in advance his practical class so that the objectives proposed by him, are achieved, so that students acquire knowledge.

O quipá (Tacinga inamoena) é uma cactácea nativa da Caatinga brasileira. Estudos sobre doenças nessa espécie são inexistentes, no entanto, manchas marrons, de etiologia até então desconhecida, tem sido observada em cladódios de quipá no estado de Alagoas. Dados preliminares indicam que fungos do gênero Fusarium podem ser responsáveis pela doença, contudo, esses dados precisam ser confirmados utilizando ferramentas adequadas. O objetivo deste estudo foi identificar e caracterizar espécies de Fusarium associadas a mancha marrom em cladódios de quipá no estado de Alagoas. Três isolados de Fusarium foram obtidos a partir de cladódios coletados em diferentes pontos do sertão do estado de Alagoas. Após confirmação da patogenicidade os isolados foram identificados com base na análise concatenada das sequencias nucleotídicas parciais dos genes EF1-α e RPB2, associadas às analises morfológicas. Foram identificadas duas espécies pertencentes ao gênero Fusarium: F. oxysporum e F. lunatum, sendo este o primeiro relato destas espécies causando mancha marrom no quipá.

ABSTRACT: Plant viruses have a wide range of weed/wild hosts, which can act as virus reservoirs. Centosema brasilianum is a wild leguminous species frequently found in association with cultivated fields in the Northeast region of the country. In March 2017, a plant of C. brasilianum was found showing symptoms of mosaic and leaf rolling, in the municipality of Maceió, state of Alagoas. In this context, the present study aimed to detect and molecular characterize viruses with DNA genomes infecting C. brasilianum. Total DNA was extracted from the leaf sample and used as a template via PCR amplification reactions assays using universal primers, aiming respectively at the detection of badnavirus and begomovirus. Partial sequences were obtained for the badnavirus RT/RNaseH and begomovirus DNA-A regions. Comparisons of paired sequences and phylogenetic analyzes indicated the presence of coinfection in C. brasilianum by badnavirus and begomovirus. The isolate BR:Mac:17 should be considered a putative new species of badnavirus, for which the name ‘Centrosema bacilliform virus’ (CenBV) is proposed. This species was phylogenetically more related to Dioscorea bacilliform AL virus (DBALV, KX008573), from the Dioscorea rotundata. Meanwhile, the isolate BR:Mac2:17 is a Begomovirus, probably of the species Bean golden mosaic virus (BGMV). The results demonstrate that C. brasilianum can act as a reservoir of badnavirus and begomovirus in the absence of culture in the field.

ABSTRACT: The semiarid region of Brazil is characterized by the high susceptibility of its agricultural systems to climatic fluctuations, which is maximized by the productive methods employed. In this region, bean (Phaseolus vulgaris L.) is one of the main crops produced, serving as an important food source for local families. In this sense, this study aimed to analyze the dynamics of bean production in the municipality of Gado Bravo, Semi-arid of Paraíba, in the period 2000-2019. The data used were extracted from the IBGE Municipal Agricultural Production information database, using the Automatic Recovery System (SIDRA). Information regarding annual rainfall in Gado Bravo was obtained through the Executive Water Management Agency of the State of Paraíba (AESA). The data were submitted to   principal component analysis (PCA). High variability was observed in the local productive aspects of the bean culture, with the presence in some years of discrepancies between the planted area and the harvested area. Low productivity of this culture in the municipality was also observed, which can be attributed to the low technification used locally and to the events of climatic vulnerability. In view of the importance of bean culture for the municipality of Gado Bravo, actions to encourage the improvement of the production rates of this legume should be encouraged and implemented.

Brassinosteroid is a hormone that in addition to favoring the growth and development of the plant is pointed out as attenuator of the negative effects caused by water stress in vegetables. The papaya has socioeconomic importance and the water deficit is a limiting factor to its growth, therefore, it was aimed to evaluate the effects caused by the application of epibrassinolide (C28H48O6), a brassinosteroid analogue, during the vegetative phase of the papaya under different irrigation slides. The experiment was conducted in the experimental field belonging to the State University of Paraíba, Catolé do Rocha -PB campus, using the Hawaí variety. In factorial scheme 5x2, with four blocks and five irrigation slides (60, 80, 100, 120, 140% of reference evapotranspiration-ET0), with brassinosteroid (concentration 1.0 mg L-1) and without brassinosteroid. The hormone was applied via the leaves at 60 days after transplanting for two consecutive days, this procedure being carried out inside a closed chamber and using a manual sprayer, 35 days after the complete exposure of the plants to the treatments, parameters were evaluated. at which it was found that there was a significant interactive effect between the factors studied (blades x hormone) in most of the variables evaluated. Smaller irrigation depths promoted lower height, diameter, number of leaves, leaf area and root volume of papaya seedlings. The use of 100% of the reference evapotranspiration provided greater height, stem and root moisture. The application of 1.0 mg L-1 of the hormone optimized plant growth in the seedling production phase, however, it did not alleviate the harmful effects of the water deficit.

The Caatinga biome is characterized by xerophyte vegetation and has a rich floristic diversity, but is fragmented by anthropic action. This study aimed to evaluate the floristic and structural differences between Caatinga fragments with different levels of conservation in the state of Piauí. Twenty-six plots of 20 m were × 20 m, divided into two areas (AI and AII). All living individuals with diameter at breast height were measured ≥ 5 cm. In The IA, 1532 living individuals were measured distributed in 14 botanical families and 38 species. The families with the highest number of species were Fabaceae (18), Apocynaceae (2) Myrtaceae (2) and Combretaceae (2). In area II, 787 individuals, 10 families and 30 species were sampled. The families Fabaceae (16), Combretaceae (2) and Euphorbiaceae (2) were the most representative in number of species. The Shannon diversity and pielou equability indices were 2.71 nats/ind and 0.76 AI and 2.60 nats.ind-1 0.75 AII, respectively. The species Combretum glaucocarpum, Cenostigma macrophyllum, Pterocarpus villosus, Hymenaea eriogyne and Ephedranthus pisocarpus together contributed 56.28% of the importance value in AI. Combretum glaucocarpum, Pityrocarpa moniliformis, Cenostigma macrophyllum, Combretum leprosum and Machaerium sp, together contributed 56.40% of the importance value in AII. In both areas there were differences in phytosociological parameters, which explains distinct regeneration processes.

ABSTRACT: Enteroparasitosis represents a serious public health problem, especially in underdeveloped countries, affecting populations that are in conditions of social vulnerability. The research analyzes the epidemiological and spatial scenario of schistosomiasis and geohelminthosis, in the state of Piauí. The study is epidemiological, descriptive, retrospective, quantitative and analytical approach, with collection of secondary data in the DATASUS Information System (SISPCE, SINAN, SIH, SIM) for the years 2011 to 2017 and the use of GIS for spatial analysis. Between 2008 to 2010 the prevalence of infection for schistosomiasis was 0.04% and geohelmintheses 0.7% found only in the municipality of Picos. However, between 2011 and 2017, human schistosomiasis was found in 6 others, with higher occurrence in Picos (53.8%). Of the total number of parasitized by S. mansoni, 61.5% are male, aged between 20 and 29 years, 76.9% are brown, originating from the urban and rural areas in equal proportion and more than half of all cases 53.8% are reported. Deaths from schistosomiasis were predominant in males (100%) between 2008- 2016. Infection by geohelminthesis affected 3.7% of individuals, with a higher prevalence of helminths A. lumbricoide 54.1%, followed by T. trichuria 23, 7% and hookworms 22.1%. The presence of these enteroparasitoses requires the adoption of effective public policies for sanitation of the environment, housing, education and health, in addition to the adoption of strategies that facilitate the knowledge on the forms of contagion and prevention.

ABSTRACT: The present study involves phytochemical investigation, phenol content and allelopathic potential of Croton heliotropiifolius Kunth extract in the germination of Digitaria insularis (L.) Fedde. with  extracts ethanolic and aqueous  of C. heliotropiifolius leaf; was performed prospected secondary metabolites  and Ultraviolet–visible (UV–visible) spectrophotometry tests for total phenols and flavonoids. The germination bioassay was performed in a BOD chamber (12L:12D) with plant extracts at 100, 50, 25 and 10%, with water as control against D. insularis seeds. The germination percentage (G%), germination speed index (IVG), abnormal seedlings (PAn%), root length and aerial part (CR and CPA) were evaluated. The extracts reduced the germination and development of the target species indicated by G% and IVG from the concentration of 10%. The same occurred with the variables PAn%, CR and CPA. In both extracts the presence of secondary metabolites was indicated, the phenol content obtained was 0.3422 mg EAG/g for the ethanolic extract and 0.375 mg EAG/g for the aqueous extract, for the flavonoids 0.1071 mg EQ/g in ethanolic extract and 0.0110 mg EQ/g in aqueous extract. The extracts demonstrated a reduction in germination and alteration in the physiology of Digitaria insularis (L.) Fedde seeds. KEYWORDS: Extracts, Secondary Metabolites, Germination.

This text has as its primary purpose the discussion of the situation from the concept of cities in general. It discusses its shift from a place of consumption to a place of resilience, resulting in the flânerie's death. From a Benjaminian look, we seek to build a dialogue between Walter Benjamin's philosophy and geography and literature as a condition in the possibility of this new moment in the urban concept during the COVID-19 pandemic. We sought in Walter Benjamin's thoughts some reflections about the situation from the modern man in Charles Baudelaire's Paris, where the philosopher offers a set of images and diagrams from this contemporary and lyrical poet - fencer, bohemian, flâneur, detective, cheater, player, and prostitute. In this sense, we can then read this general concept of city and its images in this pandemic, in the poetic geography from the urban space. They are the images which form the constellation of the poet's heroic or anti-heroic task which chose the allegory as a single form of treating modernity, in this case highlighting the image of the flâneur and the rogue as the allegorist representing the modernity in the capital of consumption, the Paris from the XIX century. We then pose our look in the flâneur's image and its disappearance in the pandemic moment and the condition of resilience from the urban system and its perturbations. KEYWORDS: City. Modernity. Merchandise. Capitalism.

ABSTRACT: Education on perspective of inclusion, it still represents a complex challenge, especially due to the problems faced in the public system. The main objective of this study was to discuss the process of school inclusion and its relationship with the challenges of teaching practice from the perspective of public basic education in Brazil. This is a review of narrative literature, which adopts the technique of bibliographic and documentary research. It was found that school inclusion seeks education for all in the same context, this does not represent the normalization of difference, but the understanding of it as diversity. In this context, factors such as: overcrowding in classrooms; insufficient teaching materials, architectural and pedagogical accessibility; teacher unpreparedness and non-execution of public policies are still challenges in basic public education, determinants of non-compliance with the principles of inclusive education. Therefore, it becomes a way to overcome these impasses by revising the curricula and political pedagogical projects, greater financial investments to meet the demands, restructuring public policies in line with the reality of the regions, training teachers, creating tools to improve the teaching work and, above all, the change in attitudes in the recognition and appreciation of the human being. It involves society as a whole and needs specific conditions to be put into practice, among many: the valorization of education as a practice of freedom, the recognition of difference as potential and the collective effort in adapting development opportunities.

ABSTRACT: Alismataceae consists in a family of semi-aquatic or aquatic plants occurring in swamps, rivers and lakes. Currently, 11 genera are considered, with 75 species in the world. However, there is a lack of taxonomic consensus to recognize and allocate the species in the genera and palynology can act as a tool to assist in the identification and organization of this family. This study aimed to describe the pollen morphology of Alismataceae species available in the herbariums Vasconcelos Sobrinho (PEURF / UFRPE), Geraldo Mariz (UFP / UFPE) and of the Agronomic Institute of Pernambuco (IPA). In addition we collected informations in the literature about pollinators of the species analyzed. Acetolysis was performed for species available in the PEUFR Herbarium collection (n = 5). For the other classified species, pollen descriptions were used based on searches in the literature. Twenty-nine species were found in the three herbariums. Acetolysis proves efficient to be used as one of the parameters for delimiting the taxon at the level of genus or species for this family. Protodiscelis spp. bees were the most commonly cited in the literature, acting as the main pollinators of Alismataceae species. KEYWORDS: Aquatic plant, Bees, Pollen.

ABSTRACT: This article aims to reflect how Afro-Brazilian literature (IANNI, 1988; Diogo, 2016; Pereira, 2017) contributes to the construction of an anti-racist education (MUNANGA, 2005; CARNEIRO, 2005; LIMA, 2005) through the work The Slave, by Maria Firmina dos Reis. As it is an article of conceptual reflection, the work A Escrava is approached as a discursive social practice in which subjects, through it, interact in and with the world around them. In this sense, the speeches of Maria Firmina do Reis raise questions about social identities and positions of black subjects and black women in social relations at the time and which persist today. For this reason, A Escrava is configured as a proposal for an emancipatory (FREIRE, 2005) and anti-racist educational practice through which knowledge and beliefs that enable the approximation of current subjects with stories, memories, experiences and experiences told by other subjects can be discussed who narrate, through their works, the trajectories of their silences and struggles as a result of their race, color and gender. KEYWORDS: Racism, Gender, Emancipation, Literature.

Introduction: Motorcycle accidents on federal highways cause material and emotional damage and are a serious public health problem. Objective: To characterize the epidemiological profile of motorcycle accidents on federal highways in the State of Ceará, Brazil. Method: Longitudinal, descriptive, documentary, quantitative and comparative study based on secondary data obtained from the Federal Highway Police database on traffic accidents on federal highways in the State of Ceará occurred during the years 2010 to 2018. These data were analyzed in relation to the total number of accidents, the variants related to the victims, time and geographical conditions. Results: We quantified 2042 accidents with an annual average of 268 accidents that occurred mainly in 2012, most with male victims (85%), young adults aged 20 to 40 years (59%), occurring due to lack of attention in driving on all days of the week. The federal roads with the highest number of accidents were 020, 116 and 222. Conclusion: The motorcycle accidents on federal highways in the State of Ceará are a frequent public health problem. It is expected that this study can alert motorcyclists and to transport and health managers for the need for development and adoption of emergency preventive strategies.

ABSTRACT: Considering the importance of Fritz Müller for the History of Science and for the dissemination and popularization of scientific knowledge in Brazil, it is also possible to carry out expressive educational works carried out in non-formal educational spaces, as in the case of. museums, in this text we analyze the Science reader-effect folder of a material that is released by the Fritz Müller Ecology Museum, located in the city of Blumenau - Santa Catarina. Our objective is to understand how to circulate and textualize scientific knowledge, materialized without reference to a brochure, we can lead its readers to produce specific meaning effects on Science. For it, we refer to the theoretical-methodological assumptions of Pecheutian Discourse Analysis, mainly in the studies by Eni Orlandi. Thus, starting from notions such as textualization, reader-effect, interdiscourse and production conditions, we try to understand the possible effects of meaning and gestures of interpretation from discourses and ways in which you are described in this scientific popularization material. Our results are suitable for discursive regularities, such as shifts in meanings and silences about Science and a scientific position, or that it raises or directs certain reading gestures and implies a certain way of reading, determined by power relations. KEYWORDS: Scientific dissemination, Non-formal education, Discourse Analysis.

ABSTRACT: This is an integrative literature review whose objective was to review the main pedagogical games used in teaching natural sciences in elementary school and whether these are effective in learning. This review consisted of a synthesis of studies already published in journals from 2010 to 2020. The following databases were searched: Capes journals, Educational Resources Information (ERIC) and academic Google. 15 studies that contemplated the research objective were reviewed. The authors agree on the importance of using educational games as a didactic resource in teaching this curricular component. It is concluded that pedagogical games are an excellent complementary and alternative tool for teaching nature sciences in elementary school, since they provide the ease of the teaching-learning process, also enabling a better teacher-student interaction.

RESUMO: Introdução: O ensino da saúde mental na graduação em enfermagem vem passando por muitas transformações em sua estrutura, tanto na organização das aulas teóricas e métodos de ensino como nas práticas nos serviços de saúde mental, gerando alguns desafios para os estudantes, professores e demais envolvidos. Objetivo: identificar na literatura a percepção do docente de enfermagem sobre a formação em saúde mental no Brasil. Métodos: revisão integrativa da literatura realizada nas bases de dados LILACS®, Web of Science®, Scopus® e CINAHL® através de uma estratégia utilizada com descritores disponibilizados no DeCS e MeSH e adotado o fluxograma PRISMA® para sistematização da revisão. A amostra foi composta por 09 artigos, resultante de uma triagem realizada por critérios de inclusão e exclusão, com auxílio da plataforma Rayyan®. Resultados: foram apresentados como pontos que potencializam a formação a perspectiva do ensino pautado na reforma psiquiátrica e nas políticas de saúde mental, utilização de teorias de enfermagem e do processo da Sistematização da Assistência em Enfermagem, metodologias ativas, utilização dos serviços como campo prático, além de abordar conteúdos sobre a comunicação terapêutica, trabalho com a família, entre outros. Os aspectos que causam vulnerabilidade no processo de ensino-aprendizagem em saúde mental são a pouca carga horária, a não participação dos docentes na construção da matriz, conteúdos generalistas e superficiais, foco nas psicopatologias, poucas atividades práticas e a dualidade do campo psiquiátrico e a atenção psicossocial. Conclusão: o ensino da saúde mental ainda é muito amplo, generalizado e fragmentado, não havendo aprofundamento nas temáticas, nas práticas e pouca relação com as demais disciplinas do currículo. PALAVRAS-CHAVE: Docente de enfermagem, Educação em enfermagem, Saúde mental.   ABSTRACT: Introduction: The teaching of mental health in undergraduate nursing has undergone many transformations in its structure, both in the organization of theoretical classes and teaching methods and in practices in mental health services, generating some challenges for students, teachers and others involved. Objective: to identify in the literature the perception of nursing professors about training in mental health in Brazil. Methods: integrative literature review carried out in the LILACS®, Web of Science®, Scopus® and CINAHL® databases through a strategy used with descriptors available in DeCS and MeSH and adopting the PRISMA® flowchart for systematizing the review. The sample consisted of 09 articles, resulting from a screening performed by inclusion and exclusion criteria, with the aid of the Rayyan® platform. Results: were presented as points that enhance training the perspective of teaching based on psychiatric reform and mental health policies, use of nursing theories and the process of Systematization of Nursing Care, active methodologies, use of services as a practical field, in addition to address contents about therapeutic communication, work with the family, among others. The aspects that cause vulnerability in the teaching-learning process in mental health are the short workload, the non-participation of teachers in the construction of the matrix, general and superficial content, focus on psychopathologies, few practical activities and the duality of the psychiatric field and the psychosocial care. Conclusion: the teaching of mental health is still very broad, generalized and fragmented, with no deepening of themes, practices and little relationship with other subjects in the curriculum.
