13. QUANTIFICAÇÃO DE PARÂMETROS CINÉTICOS DE NITROGÊNIO E OXIGÊNIO EM ÁGUAS SUPERFICIAIS PARA APLICAÇÃO EM MODELOS MATEMÁTICOS DE QUALIDADE DA ÁGUA. ESTUDO DE CASO: RIO MEIA PONTE, GOIÁS. / Quantification of kinetics parameter of nitrogen and oxigen on surfaces water to aplication in mathematicians models of water quality
Os modelos matemáticos ganham uma importância cada vez maior na avaliação e comparação de alternativas de manejo de corpos dágua naturais. Uma das dificuldades do uso de modelos de qualidade da água para nitrogênio e oxigênio é a ausência de dados sobre parâmetros cinéticos de reações dos processos bioquímicos. Os dados existentes hoje na li

16. A concepção de educação matemática de Henri Lebesgue
The main aim of this study was to consider the aspects which characterises Henri Lebesgues conception of Mathematics Education. Lebesgue (1875-1941), as well as being one of the most eminent mathematicians of the twentieth century and revolutionising Mathematical Analysis with the creation of a new theory of measure and hence a new definition of the integral

17. A Contribuição de José Saturnino da Costa Pereira para o Cálculo das Variações
In this work we present, a brief story on the history of the Calculus of the Variations, as well as, some of the mathematicians who had directly contributed so that he had the development, of that are an area of the widely studied Mathematics since its sprouting. We also present, the context of the time where this subject was developed in Brazil, as well as

18. The contend between Newton and Leibniz about Calculus, a divergence analysed about the correspondence in Royal Society / Disputa entre Newton e Leibniz sobre o calculo: uma divergência, analisada sobre as correspondências na Royal Society
In this work we present, in a general and summarized way, the differential and integral calculus origin, developing an examination particularly on thinkers and mathematicians works, among these the English Sir Isaac Newton and the German Baron Gottfried Hilhelm von Leibniz, through their correspondences. How and why Newton and Leibniz thought on the key conc

19. A presença de Nicolas Bourbaki na Universidade de São Paulo
This work aimed to establish the importance of the French group called Nicolas Bourbaki in the development of the mathematical research and teaching instruction at the Faculdade de Filosofia, Ciências e Letras da Universidade de São Paulo. The reasons for the presence, for intermittent periods, from 1945 to 1966, of some of the most important mathematician

20. Um sistema presa-predador com evasão mediada por feromônio de alarme / A predator-prey model with pursuit and evasion triggered by alarm pheromones
Pattern, structure and emergent collective properties are ubiquitous in systems with many units (alive or inanimated) coupled through nonlinear interactions. Within this context, the study of cooperative phenomena in population dynamics of ecological interest has attracted the attention of the mathematicians and physicists since Lotka and Volterra in the 192

22. Uncertainties regarding dengue modeling in Rio de Janeiro, Brazil
Dengue fever is currently the most important arthropod-borne viral disease in Brazil. Mathematical modeling of disease dynamics is a very useful tool for the evaluation of control measures. To be used in decision-making, however, a mathematical model must be carefully parameterized and validated with epidemiological and entomological data. In this work, we d

24. Contra contra o metodo : Galileu na rota da analise-e-sintese : um paralelo entre a questão da interpretação do metodo de analise-e-sintese e a questão do metodo em Galileu
This work intends to show as a first thesis, that the analysis-synthesis method of the old Greek mathematicians can be used as a conceptual model for the method of discovery and proof (resolutive and compositive) developed by Galileo in the natural sciences. The second thesis argues that the aspects involved in the problem of the interpretation of the Analys
