1. Electrochemical and Optical Investigation of Conductive Polymer and MWCNT Nanocomposite Film
Composites of multi-walled carbon nanotubes (MWCNT) and conductive polymer with good uniformity were prepared by electropolymerization. Molecular modeling calculations were carried out for electroactive monomer (OAP) polymerization with density functional theory (DFT) level using 6-311G(d,p) basis set for all atoms and Gaussian 03 program package. The reflec

2. Obstáculos à aprendizagem de conceitos algébricos no ensino fundamental: uma tentativa de aproximação entre os obstáculos epistemológicos e a teoria dos campos conceituais / Learning obstacles involved in the learning of algebraic concepts in elementary school: an attempt approach between epistemological obstacles and theory of conceptual fields.
The aim of this study is to examine obstacles and understand difficulties involved in the learning of Algebra in elementary school. The work consists in a review of the academic production and theoretical studies concerning the construction of the idea of obstacles, difficulties and errors in the learning of Mathematics in Brazil and overseas. The analyses o

3. Curvas algébricas sobre corpos finitos / Algebraic curves over finite fields
A Teoria das curvas algébricas sobre corpos finitos é de fundamental importância para a matemática e tem aplicações essenciais em muitas áreas, tais como Geometria Finita, Teoria dos Números, Teoria de Grafos e Teoria de Códigos. Neste trabalho tratamos do segmento algébrico desta teoria, isto é, corpos de funções algébricas, inicialmente sobre

4. Interger fatorization and groups on conics / Fatoração de inteiros e grupos sobre conicas
The objective of this paper is to factorize integer number using rational points on the unitary circle. Also, it intends to determinate some groups on the conics. The research begins with the basic concepts of Algebra and Number Theory ensuring that the rational points set on the unitary circle has a structure of group. From this set is possible to extend th

5. Sobre codigos hermitianos generalizados / On generalized hermitian codes
We study Goppa codes (GH codes) based on certain algebraic function fields whose number of rational places is large. These codes generalize the well-known Hermitian codes; thus we might expect that they have good parameters. Bulygin (IEEE Trans. Inform. Theory 52 (10), 46644669 (2006)) initiate the study of GH-codes; while he considered only the even chara

6. Goppa geometry codes via elementary methods / Codigos geometricos de Goppa via metodos elementares
The central objective of this dissertation was to present the Goppa Geometry Codes via elementary methods which were introduced by J. H. van Lint, R. Pellikaan and T. Hfhold about 1998. On the first past of such dissertation are presented the fundamental concepts about fields of rational functions of an algebraic curve in the direction as to define the Goppa

7. O Teorema do h-cobordismo e a conjectura generalizada de PoincarÃ
The work of the following way In the first chapter it is developed to a list definitions and theorems that we found but important on subjects such as Topology, Differential Manifolds and aspects of the Algebraic Topology, which will be used in the following chapters. We considered advisable to indicate the demonstrations of the theorems, thus, like commentar
