1. Método dos elementos finitos e técnicas de enriquecimento da aproximação aplicados à análise de tubos cilíndricos e cascas esféricas / Finite Element Method and techniques of enrichment of approximation applied to the analysis of cylindrical tubes and spherical shells
It is known that the Finite Element Method in its conventional form is a powerful technique in the modern structural calculus. However, if the problem has singularities, as boundary effects typically introduced by the support into shell structures, the analysis may demand high refinement of the mesh. In order to resolve this type of problem more efficiently,

2. MODELO PARA ANÁLISE DA ESTABILIDADE DE DUTOS EM MEIO ELÁSTICO / ANALYTICAL MODEL FOR STABILITY ANALYSIS OF TUBES ON ELASTIC MEDIA
With the growth and advance of the petroleum industry there is a need for better transportation facilities for liquid and gaseous materials. Concerns are raised with respect to savings in materials in structures and environmental problemas connected with failures and spills. Usual transportation media are cilindrical tubes, functioning as pipelines embedded

3. A espermiogenese em Boophilus microplus (Canestrini, 1887) (Acari:ixodidae) : aspectos estruturais e ultra-estruturais
The objective of this study was to describe the spermatogenesis of the cattle tick (Boophilus microplus) (Canestrini, 1887), based on histological, histochemical, morphologic and ultrastructural infromation. Spermatogenesis occurs in the testis of ticks which begin their blood repast. The gametic cell lineage is isolated in cysts. Spermiogenesis begins in th
