4. Efeitos da formação de classes de equivalência sobre a solução de problemas de adição e subtração / Some effects of equivalence class formation over the solution of addition and subtraction problems
Research has shown that some properties of the additive problem may cause difficulties to solve it. The most important are: the problems presentation form, the semantic structure and the position of the unknown. Two experiments were conducted with some methodological differences, but both with the aim of investigating if the formation of an equivalence class

5. O ß-hidroxibutirato modifica os processos de ativação e inativação dos canais para sódio e potássio em corpos celulares de neurônios dos gânglios das raizes dorsais de ratos.
Under physiological conditions, the ketone bodies -hydroxybutyrate, acetoacetate and acetone are products of -oxidation of fatty acids that occurs in hepatocytes in response to hypoglycemia. This process occurs during fasting, high fat diets (such as the ketogenic diet, used in cases of drug-resistant epilepsy) and during diabetes mellitus in order to meet t

7. Assessment of blood flow in perforating arteries during intracranial aneurysm surgery with intraoperative videoangiography using indocyanine green / Avaliação do fluxo sanguíneo em artérias perfurantes durante a cirurgia de aneurismas intracranianos através da video-angiografia intra-operatória utilizando indocianina verde
Background. Perforating arteries are commonly involved during the surgical dissection and clipping of intracranial aneurysms. Occlusion of perforating arteries may be responsible for ischemic infarction and poor outcome. The goal of this study was to describe the usefulness of near-infrared indocyanine green videoangiography (ICGA) for the intraoperative ass

8. Sistema visual de segmentação de objetos robusto à iluminação para monitoramento automático de tráfego de veículos terrestres
This study presents a proposal for a moving object segmentation system that is resistant to changes in lighting conditions and can detect and suppress moving shadows. The technique of background subtraction using mixtures of gaussians provided a basis for this study. To better deal with illumination changes, that technique was adapted to use the HSV color sp

9. Habilidades metacognitivas em matemática: desenvolvimento por meio de problemas aritméticos verbais com história no ambiente lúdico de aprendizagem de realidade suplementar / Metacognitive skills in mathematics: development through verbal arithmetic problems with history in a playful learning environment of surplus reality
This research situates within the context of investigations that seek to contribute to the teaching of mathematics in the early grades of schooling. Investigations in this area suggest that the metacognitive skills of the individual should become the focus of instruction in the classroom. The literature on mathematics education highlights the activities of p
