3. Large to medium size mammals in eucalypt plantation areas at High Pranapananema and Midle Tietê river basins, São Paulo State / Mamíferos de médio e grande porte em áreas de cultivo de eucalipto das bacias do Alto Paranapanema e Médio Tietê, Estado de São Paulo
The region comprehended amid the high portion of river Paranapanema, mid portion of river Tietê and the river Sorocaba, has a long history of human influence on landscape. This influence was intensified during the past two centuries through the passage of railroads and hydroelectric dam constructions along with other modifications that had implications on l

4. 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

5. Uma avaliação experimental e numérica do efeito da rigidez geométrica na resposta dinâmica de estruturas esbeltas sujeitas à excitação de vento. / An experimental and numerical evaluation of the geometric stiffness effect on the dynamic response of slender structures under wind excitation.
Due to a politically and economically pragmatic decision, Brazil has chosen to intensely develop its cellular phone system, in order to bypass a stage of development. Once the decision has been taken, implementation was set in an explosive pace in the 1990s decade by installing tens of thousands of stations. As the electronic systems are usually more expensi

6. Solving tangency problems by inversions and engineering applications. / Resolução de problemas de tangências por inversões e aplicações à engenharia.
A new method to solve the tenth case of Appolonius problem is presented in this study. This method is based on the geometric transformation called inversion and the concept of coaxal circumferences. Besides allowing the resolution of all configurations of the problem, it can also be used to solve other problems. We indicate the importance of the subject abou

7. Conceito de área: da composição e decomposição de figuras até as fórmulas
The objective of this research is to investigate across the use of composition and decomposition of plan forms, until the demonstration of the formula, how the area concept can be showed in the significative and motivating way to the students. To do it, we direct our studies from some hypothesis: How the reconfiguration processes of polygon forms

8. Explorando equações cartesianas e paramétricas em um ambiente informático
This research has as objective verify if in a computer science environment allows to the student to recognize some curves properties through representations and graphical interpretations in dynamic way with the use of parameters for one comprehension better of its equations. We verified that the articulating between the points of view cartesian and parametri

10. Dos complexos aos numeros de Cayley : uma abordagem geometrica
The extension ofthe numeric field beyond the complexes to the so called hypercomplex numbers is presented here through an approach which integrates the algebraic and geometric aspects of the constructions. The main goal of this dissertation was to produce an accessible text combining this two views and also aspects of the historical development of this subje

11. Modelagem de pilares paredes em edifÃcios
Slender sky-scraper constructions require pondering prior analysis features like global and localized geometrical imperfection, physical and geometrical non-linearity aspects, adequate modeling of structural elements with respect to shear-wall elements, etc. In this work, the shear-wall behavior of an actual building is studied, upon which columns were model

12. Sobre simetrias e ornamentos
This objective of this work is to study symmetries and the groups of symmetries of ornaments. Firstly, the isometries of the plane (translation, rotation, reflection and glide reflection), the cyclical and dihedral groups and the translation s group are studied. After, the classification of the discrete symmetry groups of the plane is presented: Cn and Dn, t
