A research project is being developed by PPGG/UFRN and PETROBRAS in the Xaréu Oil Field located in Ceará Basin, Northeastern Brazil. The objective of the research is to characterize a fractured carbonate reservoir, the Trairi Limestone, in order to drill a borehole with two horizontal legs taking advantage of the natural fracture system to enhance the oil recovery. The present master thesis is part of this research and its contribution is to estimate fault orientation from unoriented cores, using the method proposed by Hesthammer & Henden (2000). In order to orient a fault cutting a bed observed in the core, the bed should be previously oriented. As additional constraint to orient the bed, we use regional bedding orientation obtained from structure maps of Trairi Limestone. Because the number of cores drilled from the Trairi Limestone was too small, we analyzed all cores from the field. As geologic constraint, we admit that all faults were formed as result of the South America and Africa separation, in the context of a regional dextral strike-slip fault formation. In this context, secondary faults are manly T and R faults according Riedel s classification. We analyzed 236.5 m of cores. The dip of bedding varies from 0o to 8o, being the most frequent value equal to 2o. We interpret this result as evidence that the deformation process was manly ruptil. 77 faults were identified in the cores. These faults strike manly to NW and NE with dips, in general, inside the interval 700 - 900. We suggest that the horizontal legs of the borehole should be oriented to NW and NE in order to improve the probability of intercepting open fractures and faults

This study presents new stress orientations and magnitudes from the Potiguar basin in the continental margin of Brazil. We analyzed breakout and drilled induced fractures derived from resistivity image logs run in ten oil wells. We also used direct Shmin measurements determined from hydraulic fractures and rock strength laboratory analysis. In addition, we compared these results with 19 earthquake focal mechanisms located in the crystalline basement. We observed that stress directions and magnitudes change across the basin and its basement. In the basin, the SHmax gradient of 20.0 MPa/km and the SHmax/Shmin ratio of 1.154 indicate a normal stress regime from 0.5 to 2.0 km, whereas the SHmax gradient of 24.5MPa/km and the SHmax/Shmin ratio of 1.396 indicate a strike slip stress regime from 2.5 to 4.0 km. The deeper strike-slip stress regime in the basin is similar to the regime in the basement at 1-12 km deep. This stress regime transition is consistent with an incipient tectonic inversion process in the basin. We also noted that the SHmax direction rotates from NW SE in the western part of the Potiguar basin to E W in its central and eastern part, following roughly the shoreline geometry. It indicates that local factors, as density contrast between continental and oceanic crust and sediment loading at the continental shelf influence the stress field. The concentration of fluid pressure in faults of the lowpermeability crystalline basement and its implications to establish a critically stressed fault regime in the basement is also discussed

Cartographical representations (maps, charters and plans) are taken as didactic resources in Geography classes in the 5th grade of the municipal public schools in São José de Ribamar through a methodological approach taking into consideration the use of those resources is still worries an important part of the teachers of the Maranhão State public schools who teach in this level. Papers related to the theme, most of the time, are non accessible to the teachers of the maranhense public schools, mainly because the education instilutions, which use those resources, do it in a very incipient way. So this research proposes from the drawings of magnetccoursein the school courtyards, together with maps, charts, plans among others representation used in the classroom environment, motivate the students to a deeper interests in participating in Geography learning process in the 5th grade. Interviews, analyses of socialcultural questionnaires of the families involved in the process; observations of classes, trainings, geocartographical orientations, application of pre and posttests, discussions about the usage of cartographic representations, proposed and effectivated tasks in the classroom, as well as around the school, were the basis of the researched population. As a result of this process, it was produced a was complement didatical material showing, among others, the space in which students, for sure, will contribute in an effective way to a better teaching practice in the chain of maranhense public schools, having in mind that these geographic subjects may be taught in the level we focused our study

Muitas práticas educacionais no ensino e aprendizagem de línguas parecem ainda dominadas por uma visão de cultura essencialista, na qual os alunos, suas habilidades e atitudes de aprendizagem são caracterizadas por estereótipos problemáticos e/ou imaginários de suas culturas religiosas, étnicas e nacionais. As novas ferramentas e aplicativos para comunicação trazidos pela internet têm contribuído para o aumento de práticas comunicativas entre indivíduos de diferentes culturas e o uso da língua inglesa entre falantes não nativos, o que também tende a trazer impactos sobre a maneira como entendemos e ensinamos cultura na aprendizagem de tal língua. Este artigo pretende explicitar a visão de cultura presente nos conceitos de competência comunicativa e competência intercultural, e discutir a necessidade de reformulação do componente cultural no ensino e aprendizagem de línguas, para que ele objetive a exploração da complexidade advinda do pragmatismo dos encontros interculturais na contemporaneidade.

O objetivo deste estudo foi demonstrar se um programa de navegação pode ajudar indivíduos com deficiência visual a melhorar a acurácia na orientação dinâmica. Nove participantes com deficiência visual retornaram a um ponto de partida após percorrer rotas em linha reta e triangular. Pré e pós-avaliações foram feitas entre um período de 4 meses, durante o qual o treinamento com navegação foi realizado. Entre pré e pós-teste, erros relativos de desvios angulares (ERDA) foram diferentes apenas na tarefa em linha reta. O valor de ERDA foi maior na tarefa em linha reta possivelmente por causa da magnitude do giro inicial antes de retornar ao ponto de partida (i.e., 180º) em contraste com a tarefa triângulo (i.e., 45º). Conclui-se que, em tarefas de orientação, os erros no desvio angular dependem da amplitude do giro inicial ao retornar para o ponto de partida. Ainda, a acurácia na manutenção da direção é influenciada por um treinamento específico com navegação.

A utilização de microrganismos para fins de controle biológico de doenças em plantas tem sido muito estudada no mundo. No caso do nematóide de cisto da soja (Heterodera glycines), uma das principais doenças da soja, o controle biológico é de grande importância devido à ausência de controle químico eficiente. Para se estudar o efeito de Bacilllus subtilis sobre H. glycines, foram conduzidos alguns experimentos de casa de vegetação e laboratório. Nos trabalhos de laboratório, verificou-se, em câmara de eclosão, que a presença de B. subtilis reduz a eclosão de ovos de H. glycines estimulados com exsudatos de sementes de soja. Foi observado também que o tratamento de raiz de soja com a bactéria inibiu a migração de larvas juvenis de H. glycines para a planta em comparação à raiz não tratada com a bactéria. Nos ensaios de casa de vegetação, utilizando-se vasos com solo infestados com ovos de H. glycines, observou-se uma redução de fêmeas na raiz de soja quando o solo ou sementes foram tratadas previamente com formulação pó-molhável ou calda contendo B. subtilis, respectivamente. Com base nesses resultados e sabendo-se que H. glycines apresenta dependência de estímulo de exsudatos vegetais para eclosão e orientação das larvas, pode-se afirmar que B. subtilis interfere nesse estímulo prejudicando o desenvolvimento do ciclo do nematóide.

In this paper is proposed a methodology for semiautomatic CBERS image orientation using roads as ground control. It is based on an iterative strategy involving three steps. In the first step, an operator identifies on the image the ground control roads and supplies along them a few seed points, which could be sparsely and coarsely distributed. These seed points are used by the dynamic programming algorithm for extracting the ground control roads from the image. In the second step, it is established the correspondences between points describing the ground control roads and the corresponding ones extracted from the image. In the last step, the corresponding points are used to orient the CBERS image by using the DLT (Direct Linear Transformation). The two last steps are iterated until the convergence of the orientation process is verified. Experimental results showed that the proposed methodology was efficient with several test images. In all cases the orientation process converged. Moreover, the estimated orientation parameters allowed the registration of check roads with pixel accuracy or better.

The aim of this paper is to present a model for orientation of pushbroom sensors that allows estimating the polynomial coefficients describing the trajectory of the platform, using linear features as ground control. Considering that pushbroom image acquisition is not instantaneous, six EOP (Exterior Orientation Parameters) for each scanned line must be estimated. The sensor position and attitude parameters are modeled with a time dependent polynomial. The relationship between object and image space is established through a mathematical model based on the equivalence between the vector normal to the projection plane in the image space and to the vector normal to the rotated projection plane in the object space. The equivalence property between planes was adapted to consider the pushbroom geometry. Some experiments with simulated data corresponding to CBERS scene (China-Brazil Earth Resource Satellite) were accomplished in order to test the developed model using straight lines. Moreover, experiments with points ground with the model based on collinearity equations adapted to the pushbroom geometry were also accomplished. The obtained results showed that the proposed model can be used to estimate the EOP of pushbroom images with suitable accuracy.
