RESUMO Os conflitos e as violências no espaço escolar são compreendidos neste artigo a partir de reflexões tecidas pelos olhares de docentes e estudantes. Nosso objetivo, nesse sentido, é refletir sobre o entendimento que os sujeitos escolares constroem em relação aos conflitos e violências no cotidiano escolar. Metodologicamente, optamos pela abordagem qualitativa, utilizando técnicas de observação direta, entrevista semiestruturada, grupo de discussão e diário de campo. Em síntese, os achados deste estudo são reflexões de olhares de sujeitos escolares, não exaurindo a complexidade da discussão, mas buscando contribuir para outros possíveis debates.

ABSTRACT Conflicts and violence in the school environment are understood in this article from reflections woven through the perspectives of teachers and students. In this sense, our aim inf Weaving Perspectives on Conflict Management at School is to reflect on the understanding that school subjects build in relation to conflicts and violence in school daily life. Methodologically, we have opted for a qualitative approach, using techniques of direct observation, semi structured interview, discussion group and field diary. In short, the findings of this study are reflections from the perspectives of school subjects, not exhausting the complexity of the discussion, but seeking to contribute to other possible debates.

Abstract Eucalyptus plantations in Brazil are expanding toward the northern and mid-western regions of the country. The objective of the present study was to select clones adapted to the local conditions, with a focus on the Cerrado region. Three clonal experiments were conducted in the municipalities of Catalão, Corumbá-de-Goiás, and Luziânia, in Goiás State, with 109 genotypes of eucalypts. The experimental design consisted of a randomized complete block design with single-tree plots and 29 blocks. Diameter at breast height and total height of all trees were measured four years after planting, for use in the estimation of wood volume for each genotype. The genotype × environmental interaction was significant and predominantly (74%) complex. The genotypic correlation among environments was moderate (< 0.47), indicating that clones should be selected for specific sites. However, some clones performed relatively well across all environments, such as clones CCL21, CCL30, AEC144, CCL07, and CCL35.

RESUMO Neste relato de caso mostramos a complexidade em lidar com tumores traqueais, destacando a importância do método usado para estadiamento. Neste relato, a ecoendoscopia (EUS) foi fundamental para identificar o envolvimento da camada muscular própria esofágica por um tumor traqueal e alterar o planejamento cirúrgico do caso. O estadiamento desse tipo de tumor representa um desafio para os médicos. Não há evidências na literatura sobre quais métodos representam o padrão ouro para o estadiamento T.

SUMMARY Our case report shows the complexity of dealing with tracheal tumors, highlighting the importance of the method used for staging. In this report, endoscopic ultrasound (EUS) was crucial to identify the involvement of the esophageal muscular propria in a tracheal tumor and change the surgical planning of the case. Staging this kind of tumor represents a challenge for physicians. There is no evidence in the literature on which methods represent the gold standard for T staging.

Resumo Pancreatite necrosante com coleções pode ocorrer como complicação da pancreatite aguda. O manejo desses pacientes depende da gravidade e envolve múltiplas modalidades médicas de tratamento, como terapia clínica intensiva e intervenção cirúrgica. Neste artigo, mostramos um caso grave de necrose pancreática com ótima resolução clínica após drenagem endoscópica.

Summary Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.

An understanding of feed ingredient digestibility for the pirarucu is a fundamental step in the development of feeds that promote proper growth of the specie while in captivity. A digestibility trial was conducted with four treatments in triplicate (corn starch, corn, rice bran and wheat bran) to evaluate the digestibility of dry matter, gross energy, crude protein and amino acids by the pirarucu. We used indirect methodology with the inclusion of chromium oxide at 0.1% in the feeds. In total, 18 juveniles were used, with an average live weight of 235 ± 36 g. The sampled juveniles were trained to consume the feeds prior to testing. The corn and cornstarch presented the best apparent digestibility coefficients (ADCs) of dry matter, with 76.37% and 70.66%, respectively, followed by rice bran (46.23%) and wheat bran (45.13%). The best ADCs of crude protein were observed in corn (93.44%) and cornstarch (90.94%) compared to rice bran (68.23%) and wheat bran (68.58%). There was no significant difference in the ADC of gross energy; the values ranged from 47.10% for corn starch to 40.10% for corn. The corn and corn starch presented the best ADCs for all the amino acids evaluated, followed by rice bran and wheat bran.

El conocimiento de la digestibilidad de los ingredientes en la alimentación del pirarucu es primordial para la elaboración de pienso específico, que promueva un crecimiento óptimo. Se realizó un ensayo de digestibilidad con cuatro ingredientes energéticos, almidón de maíz, harina de maíz, salvado de arroz y salvado de trigo para la evaluación de las digestibilidades de materia seca, energía bruta, proteína bruta y aminoácidos. Se utilizaron 18 juveniles con peso de 235 ± 36 g. La harina de maíz y el almidón de maíz presentan los mejores coeficientes de digestibilidad aparente (CDA) de la materia seca, 76,37% y 70,66% respectivamente, seguidos por el salvado de arroz (46,23%) y salvado de trigo (45,13%). Los mejores CDA de la proteína bruta se determinaron para harina de maíz (93,44%) y almidón de maíz (90,94%), en relación al salvado de arroz (68,23%) y salvado de trigo (68,58%). Para el CDA de la energía bruta no fue registrada diferencia estadística, variando entre 47,10% para el almidón de maíz y a 40,10%, para la harina de maíz. La harina de maíz y el almidón de maíz presentaron los mejores CDA de todos los aminoácidos evaluados, seguidos por el salvado de arroz y salvado de trigo.
