Capacidade de termoplastificação da guta-percha com diferentes conicidades

jObjective: The objective of this study was to evaluate the thermoplasticity of the gutta-percha cones used for root canal obturation: Dentsply convencional (Dentsply Ind. e Com., Petrópolis, RJ, Brazil), Dentsply 0.04, (Dentsply Ind. e Com., Petrópolis, RJ, Brazil), Antaeos 0.04 (VDW GmbH, Munich, Germany), ProTaper (Dentsply Ind. e Com., Petrópolis, RJ, Brazil) and Alfa 0.06 (VDW GmbH, Munich, Germany). Material and method: Specimens of each material (n = 10) were prepared after heating. After 24 hours were again heated to 70 °C and placed between two glass plates and subjected to a compression of 5 kg for 2 minutes. The scanned image of the groups before and after the compression was analyzed with the software Image Tool (UTHSCSA Image Tool for Windows version 3.0, San Antonio, TX, USA). The flow capacity of the different materials was determined by the difference between the initial and final area of each specimen. The results were submitted to ANOVA and Tukey test with significance level of 5%. Result: Among the material evaluated, the gutta-percha cones Alpha 0.06 and ProTaper presented more thermoplasticity than other groups (p < 0.05). The Dentsply gutta-percha presented thermoplasticity intermediate. The groups Dentsply 0.04 and 0.04 showed lower thermoplasticity after heating (p > 0.05). Conclusion: The gutta-percha present different property of thermoplasticity, which is important to selection of thermoplastic obturation techniques.

A educação infantil sob a perspectiva da pedagogia Waldorf

The Waldorf pedagogy, based on anthroposophy, was designed by Rudolf Steiner in Germany. The first school was founded in 1919. The main objective of this proposal is human development. From the literature survey, this paper presents concepts and principles of Waldorf education, as well as its history, motivations and characteristics, aiming to increase the understanding of this Pedagogy and describing its foundations. The literature search was performed using books and data. While result of bases, from the study of the theo retical concepts, it was possible to describe the fundamentals, present concepts and principles, in addition to expanding the understanding of the Waldorf pedagogy. Starting from the Waldorf context, were also exposed the principle sofearly childhood education

Deutsche Welle Brasil: construção da notícia e representação social

Zusammenfassung: In dieser Studie wurde untersucht, wie Nachrichten, die vom Nachrichtenportal Deutsche Welle in portugiesischer Sprache veröffentlicht werden, produziert werden und inwieweit sie Brasilien und Deutschland bezüglich kulturellen, politischen und wirtschaftlichen Aspekten repräsentieren. Der staatliche deutsche Auslandsrundfunk zeichnet sich durch seine internationale Reichweite aus und schafft Dialoge zwischen Deutschland und anderen Nationen. Angesichts der Schnittstelle zwischen Journalismus und Internet, haben wir uns auf den Sender Deutsche Welle, und dort vor allem auf die brasilianische Nachrichtenredaktion fokussiert. Dadurch war es möglich, den Kontext, in dem der analysierte journalistische Inhalt produziert wird, genau zu verstehen. Die Nachrichten wurden über einen Zeitraum von einer Woche im Portal gesammelt und anschließend einer quantitativen und qualitativen Inhaltsanalyse unterzogen (BARDIN, 2009). Die Ergebnisse zeigen, wie die Inhalte beide Länder repräsentieren und gleichzeitig die Redaktionsstrategie des Senders bestätigt wird. In Anbetracht des Effekts, den die Nachrichten und die übermittelte Repräsentation der beiden Länder in den Beiträgen auf die Meinungsbildung der Zielgruppe haben könnten, trägt diese Studie zum wissenschaftlichen Verständnis im journalistischen Bereich bei und regt zu weitere Studien über die Deutsche Welle an

A Sancta Sapientia Medieval: enigma e mistério no teatro cristão de Rosvita de Ganderseheim

Within the scope of Literary Studies, theory, criticism, and historiography about the literature produced in the Middle Ages developed considerably from 1940 on, with the works of Ernst Curtius, Mikhail Bakhtin, and Erich Auerbach. In spite of the progress made, some specific aspects remain in the shadow, with incursions which were punctual though meaningful: that is the case of the critic fortunes about women‟s literary production in that period. Rosvita was a canoness and lived in the Benedictine convent of Gandersheim (Germany), in the 10th century A.D. Coming under Terence‟s influence, she wrote theater plays in Latin in which she figuratively presented theological issues in order to spread the Christian doctrine. The martyrdom issue deserved to be put in relief and was the focal point of the play Wisdom, which took place at the time of the Roman emperor Adrian. This paper analyzes that dramatic text discussing, at the end, how the categories of symbol, enigma, allegory, and mystery are organized by the author as expressive resources and structural elements.
