14. As aplicações e contribuições da geometria plana na educação de jovens e adultos no ensino fundamental por meio de unidade de aprendizagem
The application of learning units in plane geometry brings the teacher a new way of teaching. The students reconstruct knowledge relating the everyday practices and knowledge to mathematics in order to enable meaningful learning. The research was conducted in a private school in the city of Farroupilha-RS with students from a class of adult education (EJA).

15. Situações de aprendizagem: a circunferência, a mediatriz e uma abordagem com o Geogebra
The research reported here describes a qualitative research, which was based in the Theory of Didactic Situations and in assumptions concerning the use of teaching strategies mediated by technologies in geometry. The didactic sequence proposed in this study aims to enable the participants, students in ninth grade of elementary school and first year of high s

16. LIQUID-LIQUID DISPLACEMENT FLOWS IN A HELE-SHAW CELL INCLUDING NON-NEWTONIAN EFFECTS / DESLOCAMENTO DE LÍQUIDOS EM CÉLULA DE HELE-SHAW CONSIDERANDO EFEITOS NÃO NEWTONIANOS
This work studied the displacement of fluids in porous media using a Hele-Shaw cell. Specifically, was investigated experimentally the displacement of a non-Newtonian fluid by a Newtonian in a rectangular Hele-Shaw cell. The Saffman-Taylor or viscous fingering instability occurs when one fluid pushes a more viscous one, and a Hele-Shaw is a convenient tool t

17. Simulação da geometria e do desempenho do detector de antineutrinos do Projeto Angra / Simulation of the design and performance of the detector antineutrinos Angra Project
In this work is presented a comparative study between some geometries for the Neutrinos Angra Project detector. This Project was born from a colaboration that is dedicated to the construction of a compact antineutrinos detector for monitoring, in real time, the thermal power of Angra II nuclear reactor. Through the antineutrinos ux is possible to get informa

18. Estudo da deterioração de marquises de concreto armado nas cidades de Uberlândia e Bambuí / Study if Deterioration of Constructed Concrete Skyways in the city of Uberlândia and Bambuí
In recent years the number of the constructed concrete marquees with pathological manifestations has grow in Brazil, and consequences have caused them to be structurally weak, which has generally lead to fatalities. As preventive action, it becomes necessary that the projects and construction thereof be improved in quality, that found pathological causes be

19. Sistema Computacional para Análise Avançada Estática e Dinâmica de Estruturas Metálicas
A new computational tool for the advanced static and dynamic analysis of steel framed structures based on the Finite Element Method has been developed and is presented herein. Understanding the static and dynamic behavior of a structure is essential for designing structures that are lighter and slenderer without affecting their safety and quality standards.

20. Um roteiro para a criação de programa computacional dedicado à geração de pré-projeto arquitetônico de habitações sociais: realimentação de modelo a partir de avaliações pós-ocupação / A roadmap for the creation of dedicated software the generation of pre-architectural project of social housing: feedback model from Post-Occupancy Evaluations
The possibility of living in environments that have been sized on the basis of anthropometric studies and post-occupancy evaluations (POEs) of the functionality of buildings is the consequence of architectural design processes yet to be consolidated. This technology has enabled greater control over all stages in the construction of buildings, the pre-design

22. Construções geométricas: uma alternativa para desenvolver conhecimentos acerca da demonstração em uma formação continuada
The purpose of this study is to analyze a sequence of activities carried out with in service teachers, aiming the construction of the definition of line bisector of a segment and, from this definition, to allow them to demonstrate inherent properties of this mathematical object. Moreover, the study also aimed that the teachers were able to justify it mathema

23. Proposta metodológica para modelagem geométrica a partir de imagens médicas
The great technological development in decades has brought changes of great importance in several areas of knowledge. In engineering, you can cite as one of those modifications to change the ideology and construction of mechanical projects, related to the emergence of CAD systems. In medicine, major changes have emerged with the advances offered by Radiology

24. Construção dos conceitos geométricos num contexto de formação inicial de professores dos anos iniciais do ensino fundamental
Several scientific papers denounce the abandonment of the teaching of geometry in the elementary school and one of the reasons given is the unpreparedness of the teacher. This paper analyzes, in the context of initial training, the acquisition of skills in geometry, through the analysis of the participation and written production of students from the course
