O estudo objetivou investigar os casos de violência nas relações dos acadêmicos a fim de conhecer a prevalência de bullying dentro da Universidade Federal de Rondônia-Campus Porto Velho. Tratou-se de um estudo quantitativo no qual foi efetuado um inquérito epidemiológico que consistiu em um delineamento de pesquisa que possibilitou conhecer as vivências de violência apresentadas pelos alunos de ensino superior da cidade em evidência. Para coleta de dados foi utilizado um questionário validado que foi aplicado durante visitas à Universidade, com alunos dos diversos cursos selecionados pela amostra quantitativa. Foram realizadas 456 entrevistas. Os resultados comprovaram que as manifestações de bullying ocorrem, principalmente, nas salas de aula (6,1%). Também foi observado que 32% afirmaram já ter passado por uma situação que considerou humilhante ou constrangedora por parte dos docentes. Mediante aos achados desta pesquisa foi possível afirmar que as manifestações de bullying estão presentes nas relações sociais da universidade.Descritores: Violência, Bullying, Ensino Superior.Behavior of students in a university of the amazon region faced with bullyingThis study aimed to investigate cases of violence in the relationship of academics to ascertain the prevalence of bullying within the Federal University of Rondônia, Porto Velho Campus. This was a quantitative study in which it was conducted a survey that consisted of a research design that helped us to understand the experiences of violence presented by the students of higher education from the city highlighted. For data collection we used a validated questionnaire that was applied during visits to the University with students from various courses selected by the sample quantity. 456 interviews were performed. Results showed that the manifestations of bullying occur mostly in the classroom (6,1%). It was also observed that 32% said they had experienced a situation considered humiliating or embarrassing by teachers. Upon the findings of this research it was possible to affirm that the manifestations of bullying are present in social relations of the university.Descriptors: Violence, Bullying, Higher Education.Conducta de estudiantes de la universidad de la amazonía frente a bullyingEl estudio tiene por objetivo investigar los casos de violencia en la relación de los académicos para conocer la prevalencia del maltrato entre iguales en la Universidad Federal de Rondónia- Campus, Puerto Viejo.

This paper provides technological characterization and preliminary studies for the concentration of talc ore from the municipality of Caçapava do Sul, RS -- Brazil, for the purpose of defining its process route. The characterization was made by in bench channel sampling, preparation of the material by comminution, followed by homogenization, fractionation, and analyses of particle size, mineralogy, chemical composition, brightness, density and humidity of the sampled material. Afterwards, magnetic separation studies were carried out using Davis tube and leaching, in order to reduce the impurities, which consisted mainly of iron oxide contamination. After preparation of the sample, it was possible to obtain a fine material of approximately 65 % passing 37 μm, with similar brightness values between all samples despite a variable distribution of Fe, Ca, Mg and Al contents. The best results of the study occurred for the sample with a granulometric cut of 100# subjected to a magnetic separation of 4050 G and later leaching at 80 °C for a time of 60 min. A maximum brightness of 72.3 % was achieved, with an increase in brightness of 10.3 % in relation to the initial brightness. This product could be applied to the paint, insecticide, textile and paper industries, requiring complementary characterization to fit further specifications.
