AGRONOMIC PERFORMANCE OF ELEPHANT GRASS CULTIVARS UNDER IRRIGATION: A SYSTEMATIC REVIEW

Elephant grass (Pennisetum purpureum Schum) is a grass species native to Africa, mainly used as forage resource. The search for adequate species and irrigation can be an alternative to increase yield and year-round availability of this forage in the Cerrado. Studies on irrigated elephant grass in the literature are still rather scarce. This review aimed to update information on the agronomic performance of elephant grass cultivars under irrigation. Methods: Articles referring to the topicirrigation of elephant grass were searched at the databases ScienceDirect, Scopus and Agris. In April 2018, two independent researchers searched at these databases considering all articles in English without restriction of year. At the three databases, a total of 357 articles were selected and downloaded, 316 of which were excluded and 41 were thoroughly read. At the end, three articles were considered in the systematic review. The best results were obtained in the period from June to October, when evapotranspiration and temperature were higher. In the second article, salinity caused reductions in vegetation index, leaf area, plant height and chlorophyll. In the last article of the review, the results were satisfactory with the use of irrigation, resulting in increased grass yield, generating greater availability of feed to cattle. With the present study it is possible to conclude that elephant grass can be a good alternative for cattle feed production, but some factors may limit its growth and development

Augmented reality and literacy: an exploratory study in regular teaching and specialized educational attendance

O presente artigo foi construído a partir de uma pesquisa exploratória realizada com alunos do Atendimento Educacional Especializado (AEE) e do ensino regular, com o intuito de despertar o interesse deles por uma história contada com o recurso da realidade aumentada (RA) e de suas contribuições para a alfabetização. Foram selecionados alunos em processo de formação, com o objetivo de estimular o interesse pela leitura através de uma história infantil denominada “Animaizinhos do Safári”, da editora Todolivro, contada com o uso de recursos de RA. Também faz parte desse trabalho uma análise dos benefícios desse recurso nessa fase. Além disso, os autores relatam as experiências e as opiniões da professora da turma com relação à utilização da RA para fins educacionais. Como resultados, percebe-se que o uso da RA auxilia os professores, proporciona aulas interativas e desperta no aluno o seu interesse pelos conteúdos escolares, além de estimular à leitura.This article was developed by an exploratory research accomplished with students from specialized educational attendance (SEA) and regular teaching, analyzing their interest by a story told with the resourse of the augmented reality (AR) and its contributions for the literacy. Some students were selected in literacy process, intending to encourage the interest by reading through a children’s story named “Animaizinhos do Safári” – (Safari Little Animals), from Todolivro publisher, told with the augmented reality resources, also analyzing the contributions of this resource in that level. Furthermore, the authors mention the teacher’s opinions and experiences in comparison with the use of augmented reality for educational purposes. As results, we notice that the use of augmented reality can help the teachers providing more interactive classes and the students can have a better interest by the school subjects and an encouragement for reading.Facultad de Informátic

Hipospadia perineal canina: relato de caso/Canine perineal hypospadias: case report

Hipospadia é uma anormalidade que ocorre em machos por falha da fusão das dobras urogenitais durante o desenvolvimento fetal, causando fechamento incompleto da uretra peniana. O meato uretral se abre na superfície ventral do eixo peniano, e o óstio ectópico da uretra pode ocorrer na glande, no escroto, no pênis, na região perianal ou na região anal. A malformação pode estar associada a outras anomalias, a sinais clínicos diversos e com gravidade variada. Este trabalho relata um caso de hipospadia perineal em um cão da raça Buldogue Francês sem sinais clínicos relacionados e, portanto, sem necessidade de cirurgia de correção. O exame clínico foi decisivo na confirmação do diagnóstico e orquiectomia indicada para a interrupção da reprodução

ENTEROPARASITOSES EM ESCOLARES DA CIDADE DE CAMPOS SALES, CE: APLICAÇÃO DO PROJETO PARASITOLOGIA NA ESCOLA

Infecções intestinais causadas por helmintos e protozoários atingem principalmente crianças em idade escolar pela falta de medidas básicas de higiene e sanitárias da sociedade. Com isso em mente o objetivo do Projeto Parasitologia na Escola foi a integração da comunidade acadêmica do curso de Ciências no enfrentamento de parasitoses intestinais e determinar a incidência em crianças de escolas públicas do município de Campos Sales, CE. O Projeto Parasitologia na Escola está dividido na fase de apresentação de atividades lúdicas com apresentação de paródias, peças teatrais e de fantoche. Na fase seguinte, foi realizado aplicação de questionários socioeconômico e de avaliação das condições sanitárias e hábitos de higiene das crianças juntamente a coleta de material parasitológico para análise no método de Hoffman. Nas análises parasitológicas o parasita mais encontrado nas amostras fecais foi Entamoeba hystolitica (45%) escola A e (40%) escola B. Quanto a análise do questionário pode-se ver que as crianças e suas famílias em sua maioria possuem hábitos adequados apesar da falta de saneamento básico, e a dificuldade em certas épocas do ano quanto ao abastecimento de água. E as crianças são tratadas quanto às parasitoses, por isso, o baixo índice de infectados na amostra pesquisada e que os seus pais e a rede pública buscam melhorar a qualidade de vida das suas crianças

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
