13. Modelo para determinação da perda de carga contínua em tubos elásticos / Model for determining the continuous head losses in elastic pipe
Total head losses are accounted in the irrigation hydraulic projects, that would be the continuous losses and the local head losses, aiming to maximize the uniformity of water distribution, characterizing an adequate pump set to the irrigation system e thus, minimizing the project implantation and annual costs. With informatics support, complex calculation p

17. O ensino de matemática na Academia Real Militar do Rio de Janeiro, de 1811 a 1874 / The teaching of mathematics at the Royal Military Academy of Rio de Janeiro, 1811-1874
In this work, the proposal is to analyze as the mathematical syllabus of the Royal Military Academy of Rio de Janeiro was conceived and his posterior adaptations, implemented between 1811, when the Academy was founded, and 1874, when the teaching of engineer become a responsibility of a civil ministry, and the Escola Central turned into Escola Politécnica.

18. Analysis of feasibility to use cabotage for transporting new cars in Brazil: a case study / Análise da viabilidade da utilização do transporte por cabotagem para a movimentação de automóveis novos no Brasil: um estudo de caso
This study aims to examine the feasibility of costal shipping of new cars by cabotage in Brazil, searching for an alternative system, since, currently, this transport is performed solely by road transportation. The use of cabotage as cargo transportation has increased since the enactment of the Modernization of Ports Law (Act 8630) in 1993. Since then, autom

19. Geometry and Arithmetic in the Conception of the Greek Doric Temples / Geometria e aritmética na concepção dos templos dóricos gregos
The Architectural conception of the Greek Doricos temples has been studied in the perspective of the Archaeology of the Architecture stricto sensu. We had verified the role and the relevance that the geometry and arithmetic applications such as the technical and methodology resources for the design development of the Greek Doric temple in V century B.C., in

20. Compared education and anthropology: educational borrowing at international schools in Brazil. / Educação comparada e antropologia: "educational borrowing" em escolas internacionais no Brasil
At international schools in São Paulo, international and transnational curricula and methodology are utilized. In mathematics, these schools teach, for instance, an algorithm for division that is not normally adopted in the Brazilian educational system. Since the majority of the students of these schools are Brazilian, this is identified as educational borr

21. Resolution of numerical hyperbolic partial differential equations nonlinear: a study aiming at recovery at oil / Resolução numérica de equações diferenciais parciais hiperbólicas não lineares: um estudo visando a recuperação de petróleo
O processo de recuperação secundária de petróleo é comumente realizado com a injeção de água no reservatório a fim de manter a pressão necessária para sua extração. Para que o investimento seja viável, os gastos com a extração têm de ser menores do que o retorno financeiro obtido com o petróleo. Para tanto, tornam-se extremamente importante

22. Linguagens de domínio específico e sensores baseados em modelos biológicos de computação
A Domain Specific Language is a specification language dedicated to a particular domain, representation technique, or solution searching method. On the other hand, a general-purpose programming language is a language designed with the goal of emulating Lambda Calculus or Turing Machine. Since general-purpose languages must accept any algorithm that can be ex

23. Mathematics in social sciences: the case of economics / A matemática nas ciências sociais: o caso da economia
The use of mathematical techniques is increasing in most disciplines of social sciences, especially in Economics, and the mathematizations supporters usually try to legitimize this process from the supposedly axiological neutrality of Mathematics, arguing, under positivist influence, that the mathematical language should be the very language of science. This

24. Reflexão sobre a Matemática e seu processo de Ensino-aprendizagem: implicações na (re)elaboração de concepções e Prática de Professores.
This study aims to go deeper into the understanding of how important reflection is for the development of the teachers practice. The produced surveys concerning this perspective the epistemology of the practice have realized that the exercise of reflection/reflective practice presents an outstanding role in the initial and continuous formation and as regards
