1. O uso do caso talidomida auxiliando na construção de significados em aulas de Química do Ensino Superior
Studies conducted in the field of education have, in many cases, highlighted the little insertion of teaching and learning theories in Natural Sciences classes, in Higher Education. We developed this study to analyze how Chemistry professors take ownership of a historical case to explain the concepts they develop in their classes. To do so, we analyzed this

2. Kinetic parameters study for the slow pyrolysis of coffee residues based on thermogravimetric analysis
Thermal decomposition of coffee husks was investigated by thermogravimetric analyses. The proximate, ultimate and composition analyses were performed. Thermogravimetric tests were realized, the material was heated to 1173 K using five heating rates: 5, 10, 15, 20, 25 K min-1. The kinetic parameters were estimated using the methods of Kissinger-Akahira-Sunose

6. Longitudinal Aerodynamic and Stability Characteristics of High-Aspect-Ratio Unmanned Aerial Vehicles in Gust Response
ABSTRACT The aim of this work is to propose an accurate and reliable numerical simulation method of gust response, so as to analyze longitudinal stability characteristics of high-aspect-ratio unmanned aerial vehicles (UAVs) under gust response. Based on the dual-time stepping method, the unsteady Navies-Stokes equation was solved. By introducing grid velocit

7. UMA AULA DE WALTHER NERNST NO BRASIL
Walther Hermann Nernst is known to have established the basis for the third law of thermodynamics and also as one of the founders of the modern physical chemistry. For his work in chemical thermodynamics, he was awarded the Nobel Prize in chemistry, in 1920. An important fact about this scientist life, not always realized, was his stay in Brazil, in 1914, fo

11. Analysis of Styrene Polymerization Without Surfactant and N2 Gas in Cylindrical Flask.
The conditions of chemical synthesis can be crucial for polymerization of styrene in such a way that it can be produced latex beads at nanometric range (ϕ < 400nm). In this work, it will be analyzed how the absence of N2 and surfactant will result in colloidal particles with high affinity to agglomerate forming two kinds of nanostructured assemblies: colloi

12. ILITIA: telehealth architecture for high-risk gestation classification
Abstract Introduction According to the World Health Organization, about 9.2% of the 28 million newborns worldwide are stillborn. Besides, about 358,000 women died due to complications related to pregnancy in 2015. Part of these deaths could have been avoided with improving prenatal care agility to recognize problems during pregnancy. Based on that, many eff
