2. Percepção do Estudante de Medicina sobre a Inserção da Radiologia no Ensino de Graduação com Uso de Metodologias Ativas
RESUMO A radiologia no curso de graduação em Medicina alcançou nova dimensão não só como instrumento de diagnóstico complementar, mas também por sua utilização como ferramenta de ensino, integrada ao estudo da anatomia e patologia, entre outros assuntos. Embora os conhecimentos da radiologia sejam bastante utilizados no ensino da medicina através

3. Modification of palm oil crystallization by phytosterol addition as a tool for structuring a low saturated lipid blend
Abstract Fat structural modifications promoted by phytosterol addition ( a hypocholesterolemic component ( to palm oil and a mixture of palm oil and canola oilwere evaluated in order to develop fats with reduced saturated fatty acids. Palm oil added with free or esterified phytosterols was investigated in terms of triacylglycerol composition, microstructure,

4. Investigation of Electromagnetic Radiation Emission during Sheet Metal Incremental Micro Forming
Edge dislocations within the plastic zone ahead of a crack tip form accelerated electric line dipoles which give rise to the electromagnetic radiation (EMR) emissions in metal and alloys. This paper reports an experimental investigation to determine EMR radiation during incremental microforming of a thin aluminum sheet. The EMR signals emit from aluminum gra

5. Diversity of the Potential 2-Methylisoborneol-Producing Genotypes in Thai Strains of Planktothricoides (Cyanobacteria)
ABSTRACT The genus Planktothricoides Suda & Watanabe is considered as a 2-methylisoborneol (MIB) producer, affecting water quality and aquatic animal products worldwide. To date, there is limited information about the diversity of this genus from Thailand. In this study, Thai Planktothricoides strains were isolated from fish ponds and reservoirs in North, No

6. CALCULATION OF CONDITIONAL EQUILIBRIUM IN SERIAL MULTIPLE PRECIPITATION OF METAL SULFIDES WITH HYDROGEN SULFIDE STREAM GENERATED FROM SODIUM SULFIDE: A DIDACTIC TOOL FOR CHEMISTRY TEACHING
Hydrogen sulfide is presented in textbooks as toxic, environmentally unacceptable species, however some positive effects in human metabolism were discovered in the last decades. It is important to offer students also some new information about this compound. As didactic tool in this case may serve serial precipitation of Cd2+, Cu2+, Zn2+, Mn2+ and Pb2+ ions

7. A characterization for the constitutive relationships of 42CrMo high strength steel by Artificial Neural Network and its application in isothermal deformation
In hot working process, the prediction of material constitutive relationship can improve the optimization design process. Recently, the artificial neural network models are considered as a powerful tool to describe the elevated temperature deformation behavior of materials. Based on the experimental data from the isothermal compressions of 42CrMo high streng

8. Modelos de distribuição de espécies de vellozia (Velloziaceae) endêmicas da Cadeia do Espinhaço e o efeito amostral sobre os mapas preditivos
The effectiveness of conservation actions depends on the knowledge of the geographical distribution of species. However, this knowledge is far from being achieved for most species, especially those occurring in mountainous tropical environments, such as the rocky fields (campos rupestres) of the Espinhaço Range, characterized by forming islands of vegetatio

9. Study of tension in the periodontal ligament using the finite elements method
Orthodontic movement is process of transformation of a physical stimulation into a force applied to a tooth, with a biological response identified as bone remodelling. Although it is possible to measure the force applied on a tooth, its distribution around the root is irregular forming areas of higher concentration of tensions, which do not correspond to the

12. Avaliação da resistência ao desgaste de aços inoxidáveis conformados por spray / Evaluation of the wear resistance of spray formed stainless steel
The aim of this work was the study of the microstructure and the wear resistance of two stainless steels, the ferritic-AIF with 27% Cr and the superduplex-SDM modified with boron (3.5% wt.), processed by spray forming. The rapid solidification promoted by this process has resulted in the formation of a new structure with refined grains and metastable phases.
