Equações de 2º grau em Geometria Plana
Oliveira, Aldeck Menezes deWe started this work with a little history of trigonometry and quadratic equation to finally introduce some results relating the geometry of the triangle, of convex polygons and the conical with quadratic equations.; Começamos este trabalho com um pouco da história da trigonometria e da equa- ção de segundo grau para finalmente apresentarmos alguns resultados relacionando a geometria do triângulo, dos polígonos...
O Ensino da Matemática Financeira Utilizando a Calculadora HP 12C
Oliveira, Mayana Cybele Dantas deThis research has as object of study the teaching of Financial Mathematics, with the aid of a tool: the Financial Calculator HP 12C, preparing citizens able to manage their own budgets and the labor market. Preliminary concepts concerning the theme are presented, followed by examples in context, pointing out the main factors that facilitate the understanding of each content. Being approached through practical a...
Curvas planas: uma visão para o ensino médio
Cardim, Breno da SilveiraIn this work, we study the principles of the theory of plane curves, within the context of high school; Neste trabalho estudamos os princípios da teoria das curvas planas, tendo em mente, estudantes do ensino médio. Aqui, é proposta uma introdução ao Cálculo Diferencial e Integral àqueles estudantes, e em seguida um estudo sobre a teoria das curvas, onde alguns exemplos clássicos são apresentados, bem como, con...
Caracterização dos marcadores, desenvolvimento e validação de método analítico ...
Marinho, Alexsandro FernandesThe leaf ethanolic extract of Cissampelos sympodialis showed promising activity in different animal models of asthma. Several alkaloids have been isolated and identified in the extract, including warifteine and methylwarifteine (bisbenzylisoquinoline), as well as milonine (morphinandienone). In this work we describe the development and validation of a method for simultaneous quantification of chemical markers i...
Avaliações psicofísicas cromática e acromática de homens e mulheres expostos a ...
Oliveira, Ana Raquel deWorkers chronically exposed to a variety of organic solvents may suffer from changes in color vision and contrast sensitivity (CS). However, few studies have investigated whether there are sex-related differences in these changes, one of the factors that can change the toxicokinetics of solvents. Hence, the aim of this study was to determine whether there would be differences between women and men exposed in te...
Estudo sobre o cálculo de áreas e volumes utilizando o Método de Exaustão e o P...
Lima, Francisco do NascimentoThis study aimed to demonstrate some mathematical formulas used in geometry to serve as a reference source for teachers and students of Basic Education. We have begun with some of the great thinkers of Ancient Greece and with a discussion of the History of Geometry since its rst days in order to understand its emergency and development. We, then, have showed that the measure of a segment is a real number, that ...
Soluções Geométrica e Algébrica do Problema de Apolônio
Melo, Alysson Espedito deThis work, our main objective is to present a geometric and algebraic solution to the problem of Apollonius. The problems are as Apollonius citations in Pappus works as follows: Given three elements, each of which may be points, lines or circumference, construct a circumference passing through the point (s) and is tangent to each of the lines given, but our work will speci cally show the solutions for the case ...
Violência sexual e discriminação racial: influência na responsabilização da vítima
Albuquerque, Iara MaribondoThis work aims to investigate whether the woman's skin color and the attacker's skin color influence the responsibility attributed to the woman for the violence she suffered. Therefore, three main hypotheses were formulated that guided the conduct of three empirical studies. Study 1 tested the following hypotheses: the black female victim of sexual violence will be seen as more responsible than the white female...
Atitudes frente à homoparentalidade: uma explicação a partir de variáveis explí...
Freires, Leogildo AlvesThe present thesis aimed at knowing the correlates and predictors of attitudes toward homosexual parenting, based on explicit and implicit variables. In order to attain this objective, five studies were conducted. Study 1 aimed at mapping participants’ opinions about child adoption by homosexual parents. Participants were 484 people from general population, with mean age of 26 years (SD = 8.31). They answered t...
Números perfeitos
Cruz, Sívio OrleansIn this thesis we study some topics of the Theory of Numbers as an inspiration for future studies of Perfect Numbers and Mersenne Primes. We present some important results for our study and analyze some statements of Fermat's Little Theorem, showing the various mathematical demonstrations that proved under various logical aspects. We have clari ed some historical aspects and conjectures for perfect numbers, thr...
