This paper consists in applying the Modern Theory of Portfolio (MPT) using central position measurements for modeling the return on investment fund of a renowned financial institution and compare with the Medium- CVaR model. The measurement of risks and returns becomes increasingly important for investors to minimize their losses to maximize thus their possibilities of earnings, taking into account sudden change scenarios. We present concepts of investment funds used as data and research on central position measurements to determine which measure was more suitable. To assemble the Efficient Frontier of assets considering the method proposed measure of central position-CVaR position is used MatLab. Then, after getting the Frontier, it was possible to compare it with the Medium-CVaR model, already proven effective. Finally, we analyze the viability of the proposed model in portfolio management

This work has as main theme optimize the method of determination of fatty acids such as methyl octanoate, methyl palmitate, methyl stearate, methyl oleate, methyl linoleate and methyl linolenate in blood plasma samples from mice. The method proved to be very suitable for the analysis, in which we obtained the following linear coefficients: 0.9992, 0.9989, 0.9996, 0.9995, 0.9999 for methyl linoleate acid, methyl oleate, methyl palmitate, methyl stearate and methyl octanoate, respectively. Esterification of the samples gave good reading of chromatograms of samples without interfering peaks. The results obtained were as expected from the diet of mices

Upper canines impaction are considered the second most frequent and are associated to important esthetics and functional limitations. Among the treatment strategies described in the literature the most commonly used are the extraction of the primary canines and the surgical exposure followed by orthodontic traction, that requires an adequate interdisciplinary approach. The aim of this case report is to draw the attention of the clinician to the possibility of adapting the segmented arch technique to manage a canine impaction clinical case.

Based on the relationship between the concept of Historical Consciousness, as Jörn Rüsen and Reinhart Koselleck proposed, and the concept of Historical Explanation, proposed by Isabel Barca, the article presents an analytical course that allows you to check levels of explanation in historical narratives produced by students Brazilian and Portuguese from the interpretation of sources related to a historical fact: the transfer of the Portuguese royal family to Brazil (1808).
