2. Aplicação de processo adsortivo para dessulfurização de combustíveis utilizando fibra de coco como adsorvente
RESUMO A presença de compostos orgânicos contendo enxofre nos combustíveis é um dos contribuintes da poluição atmosférica, pois quando entram em combustão nos motores, emitem poluentes derivados do enxofre, como os óxidos (SOx), que afetam negativamente a saúde humana e o meio ambiente. A remoção do excesso de enxofre presente na gasolina pode se

3. AVALIAÇÃO DAS CAUSAS DE RETENÇÃO EM QUÍMICA GERAL NA UNIVERSIDADE FEDERAL DO AMAZONAS
Failing classes is one of the main causes students are held back in universities, which in turn has several academic, social and economic impacts. This study aims to identify factors associated with students flunking General Chemistry, as well as to propose institutional interventions that can remedy these setbacks. The methodology used was based on a concep

4. Formación de Profesores de Matemáticas desde la Etnomatemática: estado de desarrollo
Abstract The goal of this study is to contribute to our understanding of the state of research development about math professors’ training from an ethnomathematics perspective. The empirical material was selected from articles published between 1995 and 2015. The analysis was oriented around four questions: What characteristics should a school curriculum b

5. HOW WE HAVE USED ITEM RESPONSE THEORY AND CLASSROOM MANAGEMENT TO IMPROVE STUDENT SUCCESS RATES IN LARGE GENERAL CHEMISTRY CLASSES
Since 2012 we have tracked general chemistry student success rates at the University of Utah. In efforts to improve those rates we have implemented math prerequisites, changed our discussion session format, installed some metacognitive exercises aimed at the lowest quartile of students and instituted a flipped classroom model. Furthermore, using Item Respons

6. Análisis Didáctico a un Proceso de Instrucción del Método de Integración por Partes
Abstract This article presents an analysis of the structure and functioning of a sequence of math classes, with Colombian sophomore bachelor's degree in mathematics, where the method of integration by parts explained is presented. In order to do so, the model of analysis proposed by the Focus Ontosemiotic of Cognition and Instruction Mathematics was used. Th

7. Automated sugar analysis
Abstract Sugarcane monosaccharides are reducing sugars, and classical analytical methodologies (Lane-Eynon, Benedict, complexometric-EDTA, Luff-Schoorl, Musson-Walker, Somogyi-Nelson) are based on reducing copper ions in alkaline solutions. In Brazil, certain factories use Lane-Eynon, others use the equipment referred to as “REDUTEC”, and additional fact

8. Validación de la Versión en Español del Mathematics Value Inventory (MVI) entre Estudiantes Universitarios Uruguayos
AbstractBased on the expectancy-value theory, the Mathematics Value Inventory (MVI) was intended to measure math value in four areas: interest, utility, achievement and personal cost. This paper presents the validation of the Spanish version among Uruguayan university students: factorial validity through confirmatory factor analysis (CFA), gender related dif

9. Conocimiento Especializado de un Profesor de Matemáticas de Educación Primaria al Enseñar los Números Racionales
We describe the specialized knowledge of an expert Primary Education math teacher while teaching the topic of rational numbers to students of 11-12 years old. Using a category system of the subdomains of the Mathematics Teacher's Specialized Knowledge model (MTSK), a content analysis of the transcripts of 21 classes taught was performed. This allowed us to a

10. Disponibilidad y uso de TIC en escuelas latinoamericanas: incidencia en el rendimiento escolar
Enriching learning environments for students by incorporating information and communication technologies requires that schools have both computers and connectivity - in sufficient quantity and quality - to be incorporated by teachers and students into the teaching and learning process. The following research estimates the impact of computer access and use on

11. The impact of daycare attendance on math test scores for a cohort of 4th graders in Brazil
We estimate the impact of having attended center-based daycare institutions during early childhood on Math test scores at the 4th grade of elementary school. Because enrollment in daycare centers may depend on unobservable character-istics of the family and the child, we build and estimate a structural model of endogeneous choice of school to deal with the s

12. Modelagem da dinâmica vertical de coxins elastoméricos de motor através de método de redes neurais / Modeling vertical dynamic of elastomeric engine mounts using artificial neural networks
This dissertation scope is the modeling of an elastomeric mount, element which has primordial role on powertrain vibration isolation. The study of the mechanic behavior of those elastomeric materials is a field being studied for several years agor since its complexity and non-linarity of those components; and a reliable math models are competitive edge.
