Criação de zonas de alta permeabilidade em fraturas: modelagem numérica do Lajedo de Soledade, Formação Jandaíra, Bacia Potiguar

The fracturing in carbonate rocks has been attracting increasingly attention due to new oil discoveries in carbonate reservoirs. This study investigates how the fractures (faults and joints) behave when subjected to different stress fields and how their behavior may be associated with the generation of karst and consequently to increased secondary porosity in these rocks. In this study I used satellite imagery and unmanned aerial vehicle UAV images and field data to identify and map faults and joints in a carbonate outcrop, which I consider a good analogue of carbonate reservoir. The outcrop comprises rocks of the Jandaíra Formation, Potiguar Basin. Field data were modeled using the TECTOS software, which uses finite element analysis for 2D fracture modeling. I identified three sets of fractures were identified: NS, EW and NW-SE. They correspond to faults that reactivate joint sets. The Ratio of Failure by Stress (RFS) represents stress concentration and how close the rock is to failure and reach the Mohr-Coulomb envelopment. The results indicate that the tectonic stresses are concentrated in preferred structural zones, which are ideal places for carbonate dissolution. Dissolution was observed along sedimentary bedding and fractures throughout the outcrop. However, I observed that the highest values of RFS occur in fracture intersections and terminations. These are site of karst concentration. I finally suggest that there is a relationship between stress concentration and location of karst dissolution in carbonate rocks.

O processo de criação do programa Universidade para Todos - PROUNI

From the end of the 80s, the Brazilian higher education experience strong growth, coming from the private sector, which would intensify further in the late 90th Higher education has become a lucrative business. With a drop in the number of students entering and strong competition, the number of idle places in private institutions of higher education reached 49.5% in 2004. That same year, by Measure, was the University for All Program (PROUNI) program, to include high school students from public higher education, offering scholarships to those students in private HEIs. In exchange, the IES gain tax exemption. The objective of this research is to investigate the game of interest occurred in the formulation of this program and identify the model and the political game and has led to the creation of PROUNI, analyzing the process occurred since the wording of a bill, the issue of Measure Law and that the legitimacy PROUNI, with the most important changes made initial model. Since the first draft of the Law to the final Act, the PROUNI was disfigured in its main points, as the percentage of stock for paying students, the process of selection of stock and bond of the IES program. Throughout the process of creating the program, it is quite clear the performance of the institutions representing the private higher education. As reference for the analysis was based on Rational Choice Theory of Political Science. The basic argument of the methods based on rational choice is the maximization of the benefit will be the main motivation of individuals, but they can give that your goals can be achieved more effectively through institutional action and thereby discover that their conduct is shaped by institutions. Thus, individuals rationally choose to get to a certain extent constrained to join in certain institutions, whether voluntarily or not. The PROUNI was submitted by government and public policy covered by the mystical aura of the discourse of social justice and economic development, as in higher education includes a stratum of people who would not have access to the university, due to restrictions in the supply network public higher education. However, the greatest benefit from the program are the private HEIs, which through a difficult time in a scenario marked by high competition and idleness of nearly half of the vacancies offered. The PROUNI became a program that prioritizes access and not the residence of the student to higher education. More serious than a supporting program for students Fellows is a program supporting the institutions of private education

Dançando às avessas: relatos de um processo de criação

The term body without organs is present in a poem by the french writer, actor and director Antonin Artaud, written in 1947 and titled: To Have Done with the Judgement of God. I aim, in this work, from what we call investigative scenic writing, to problematize this term and its possible relations with the theater and also with some aspects of the Hindu myths. I unite the idea of the body without organs with the body in trance present in the stories of an Indian master named Caitanya Mahaprabhu. These ideas, along with the development of practices that come from some principles of Theatre Anthropology, are incentives for a creation process that highlights the work of preparation and creation of corporeal work of the actor. The relationship between the concepts and the practice raise discussions about where I stand as an actor-researcher in process

Crenças e quebranças de um corpo que dança: poéticas do benzimento na criação cênica

This work is a discussion of the artistic process of an artist-researcher made from field research with benzedeiras and benzedores the state of Rio Grande do Norte. This is an investigation on the cultural universe of the popular benzeção as poetic element to the artistic dance. To discuss the different stages of the research and the relationships between the artist-researcher, the benzedeiras/benzedores and the creation/composition scenic, the work takes as reference the triangular relationship created by anthropologist Claude Lévi-Strauss, in his discussion on the effectiveness of symbols of healing, adapted to the context of benzeção . For dialogue between tradition, popular knowledge, scientific and artistic knowledge this work approaches as analytical reference the epistemological model of the type rhizome proposed by Deleuze and Guattari, understanding it as a model that seeks to form a network of relations in different paths of research, to establish connections between elements without target them or subordinating them. In the universe of benzeção , benzedeiras and benzedores carry a symbolic power that issued in whispered prayers, in peculiar gestures that form crosses in space, heal those who seek your prayers and blessing. In this research, the mixture of popular knowledge, artistic and academic knowledge, born an artistic work in the context of Performing Arts, more specifically dance, and between branches, saints, candles and conversations the work allowed other looks poetic for our popular culture, (re)asserting their cultural and human values through the art

Corpos diferenciados e o processo de criação da performance Kahlo em Mim Eu E(m) Kahlo

The dissertation intends to develop an investigation on the artistic existence in human beings with different bodies in society at different historical moments. In this regard and based on this scenario, the study develops a description of the stigmas production and how they are established, spread and interfere with the sociability among human beings regarded as normal and those with different bodies. Regarding the scenic arts, the text describes about the participation of artists with different bodies in the scene, specifically the freak show and postdramatic theater. The text also investigates aspects of the biography and the work of mexican artist Frida Kahlo, which underpin methodological proceedings and produce contribution to the creative process of performance Kahlo em mim Eu e(m) Kahlo , which is to investigate the practice of the scene in this dissertation

Criação em processo no espetáculo Ethnotron-Ghetto Experimen

Este trabalho investigou o processo criativo do espetáculo Ethnotron-Ghetto Experiment, do Coletivo paraibano Tribo Éthnos, fundado na década de 1990 e ainda em atividade. A estratégia metodológica se dá através de estudos descritivos, valendo-se da teoria e prática de diversas linguagens artísticas presentes na obra apontada: artes visuais, performance, literatura e histórias em quadrinho; em ações realizadas pelo Coletivo ao longo dos anos, objetivando descrever e analisar o processo de criação do referido espetáculo de dança, através da minuciosa coleta de dados por meio de entrevistas abertas e semiestruturadas, e da pesquisa e captação de materiais audiovisuais. A Tribo Éthnos destaca-se na cena local na cidade de João Pessoa, e estadual, na Paraíba, visto que, nesse longo percurso de existência, além da preocupação em fundir muitas formas artísticas, bem como os artistas da Paraíba, aglutina pessoas que fazem arte em outros países e faz das danças urbanas algo instigante. A Tribo ainda preocupa-se com a troca de saberes através de palestras, oficinas, cursos e intercâmbios. A dissertação investiga o processo de criação dos artistas e, especificamente, dos dançarinos, utilizando-se principalmente do conceito de work in progress, proposto por Renato Cohen, e aplicado ao espetáculo estudado. Apresentam-se descrições dos movimentos coreográficos, do espetáculo de dança paraibano Ethnotron-Ghetto Experiment, de Dança de Rua da Era Funky, especificamente, com estilos como popping, waving, animation, strobing, floatine/ slidini, tiokine, trebing, breaking, waving, sliding, entre outros, visto serem estes parte integrante do processo de criação. Tais estilos remetem ao ilusionismo ou ao mimetismo, sugerindo, em seus movimentos truques, câmeras lentas, flutuações com os pés, entre outros. Segundo Valmir Vaz, o Coletivo, através do espetáculo, busca a integração dos corpos, procura uma libertação individual e sugere uma sensação de querer voar nas coreografias/cenas. Abordam-se os aspectos do processo criativo: o espaço cênico, o trabalho corporal, a sonoplastia e a roupa/indumentária. Trabalha-se o conceito do corpo virtual de José Gil no aspecto do corpo cênico

Flebotomíneos (Diptera: Psychodidae) em um sistema agroflorestal da Região Metropolitana de Natal, Rio Grande do Norte, Brasil

Sandflies stand out as important vectors of leishmaniasis. The females need to ingest blood meals, enabling them to transmit protozoa of the genus Leishmania, which may give rise to visceral leishmaniasis (VL) or American tegumentary leishmaniasis (ATL), in addition to transmitting other parasites. Leishmaniasis are important infirmities, distributed worldwide, whose infection results from the interaction of reservoir animals, the vector insect, parasitic protozoa and the healthy host. In the state of Rio Grande do Norte (RN), Brazil, these insects are important transmitters of VL, which usually presents in the most serious form. It occurs mainly in metropolitan areas, with the dog as its main reservoir and Lutzomyia longipalpis as the vector. ATL is most present in the highland areas of the state. In addition to hematophagia, engaged in by the females, both sexes need to ingest carbohydrates, which are essential to the sand flies energy requirements and may interfere in the development of Leishmania. The aim of this study was to determine the occurrence and abundance of sand flies in different environments on the farm belonging to the Empresa de Pesquisas Agropecuárias do RN (Institute of Agricultural Research of RN), in the municipality of Parnamirim, in order to relate this occurrence with climatological and biological references and eating habits. Three consecutive monthly collections were carried out with CDC traps in a fragment of the Atlantic Forest, in a residence, on a goat breeding farm and on cashew, dwarf and giant coconut, mango, banana, eucalyptus, acacia and bean plantations. A total of 1241 sandflies from eight species (Lutzomyia evandroi, Lutzomyia longipalpis, Lutzomyia shannoni, Lutzomyia sordellii Lutzomyia walkeri, Lutzomyia wellcomei, Lutzomyia whitmani, and Lutzomyia intermedia) were collected, most in the forest environment. L. longipalpis, the main VL transmitter, was confirmed as a species adapted to anthropic environments, whereas others such as L. wellcomei, the vector of ATL, occurred predominantly in forests. Carbohydrate characterization of the sand flies and plants of the region demonstrated that a number of exotic plants such as hay and eucalyptus may play some role in the adaptation of these species to modified environments. Breeding in laboratory showed a mean biological cycle of 53.5 days from egg to adulthood for L. shannoni and the possibility of diapause behavior in L. wellcomei. This study serves as a source of information that may contribute to the epidemiological vigilance of tegumentary and visceral leishmaniasis in the state, given that it analyzes the bioecology of transmitting species, as well as their potential to adapt to new environments
