Estudo do comportamento mecânico de estruturas de solo-cimento reforçado com fibras de coco e hastes de bambu

In this work the use of coconut fiber (coir) and bamboo shafts as reinforcement of soil-cement was studied, in order to obtain an alternative material to make stakes for fences in rural properties. The main objective was to study the effect of the addition of reinforcement to the soil-cement matrix. The effect of humidity on the mechanical properties was also analyzed. The soil-cement mortar was composed by a mixture, in equal parts, of soil and river sand, 14% in weight of cement and 10 % in weight of water. As reinforcement, different combinations of (a) coconut fiber with 15 mm mean length (0,3 %, 0,6 % and 1,2 % in weight) and (b) bamboo shafts, also in crescent quantities (2, 4 and 8 shafts per specimen) were used. For each combination 6 specimens were made and these were submitted to three point flexural test after 28 days of cure. In order to evaluate the effect of humidity, 1 specimen from each of the coconut fiber reinforced combination was immersed in water 24 hours prior to flexural test. The results of the tests carried out indicated that the addition of the reinforcement affected negatively the mechanical resistance and, on the other hand, increased the tenacity and the ductility of the material.

O Sangyo em Dolls: um encontro do Bunraku com Takeshi Kitano

This work aims to investigate the relationship between the Bunraku theater and the film Dolls (2002), by the Japanese director Takeshi Kitano. To do so, it was initially done a theoretical study of this theater, detailing its key elements, and thus allowing a direct analysis of the film to be made. The main objective here was to reveal the film‟s connections with the Bunraku. The Sangyo refers to the simultaneous presence of three arts in the Bunraku theater: the narrative, the music and the manipulation of puppets. In Dolls, the director Takeshi Kitano presents a narrative through three different stories, all built with references to the Bunraku. As in the theater the three distinct arts harmonize on stage, in Dolls three separate stories will perform in harmony within the film. By confronting the Bunraku Theater with the film Dolls, the intention is to establish the connections between the scenic language of the Bunraku, the dramaturgy of Chikamatsu and also the cinema of Kitano. These connections allow to the understanding of how characteristics of a secular art, governed by strong rules and conventions, can be presented again through another language: the cinematic language and its particular set of codes and conventions

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

Cinemática de partículas em fluidos de viscosidade variável com o tempo e sua aplicação na construção de poços de petróleo: avaliação durante paradas operacionais

The new oil reservoirs discoveries in onshore and ultra deep water offshore fields and complex trajectories require the optimization of procedures to reduce the stops operation during the well drilling, especially because the platforms and equipment high cost, and risks which are inherent to the operation. Among the most important aspects stands out the drilling fluids project and their behavior against different situations that may occur during the process. By means of sedimentation experiments, a correlation has been validated to determe the sedimentation particles velocity in variable viscosity fluids over time, applying the correction due to effective viscosity that is a shear rate and time function. The viscosity evolution over time was obtained by carrying out rheologic tests using a fixed shear rate, small enough to not interfere in the fluid gelling process. With the sedimentation particles velocity and the fluid viscosity over time equations an iterative procedure was proposed to determine the particles displacement over time. These equations were implemented in a case study to simulate the cuttings sedimentation generated in the oil well drilling during stops operation, especially in the connections and tripping, allowing the drilling fluid project in order to maintain the cuttings in suspension, avoiding risks, such as stuck pipe and in more drastic conditions, the loss of the well

Análise de modelos geológicos utilizando percolação dinâmica

In the present study we elaborated algorithms by using concepts from percolation theory which analyze the connectivity conditions in geological models of petroleum reservoirs. From the petrophysical parameters such as permeability, porosity, transmittivity and others, which may be generated by any statistical process, it is possible to determine the portion of the model with more connected cells, what the interconnected wells are, and the critical path between injector and source wells. This allows to classify the reservoir according to the modeled petrophysical parameters. This also make it possible to determine the percentage of the reservoir to which each well is connected. Generally, the connected regions and the respective minima and/or maxima in the occurrence of the petrophysical parameters studied constitute a good manner to characterize a reservoir volumetrically. Therefore, the algorithms allow to optimize the positioning of wells, offering a preview of the general conditions of the given model s connectivity. The intent is not to evaluate geological models, but to show how to interpret the deposits, how their petrophysical characteristics are spatially distributed, and how the connections between the several parts of the system are resolved, showing their critical paths and backbones. The execution of these algorithms allows us to know the properties of the model s connectivity before the work on reservoir flux simulation is started

A rede de marcação e recaptura: o caso de borboletas do gênero heliconius

(The Mark and Recapture Network: a Heliconius case study). The current pace of habitat destruction, especially in tropical landscapes, has increased the need for understanding minimum patch requirements and patch distance as tools for conserving species in forest remnants. Mark recapture and tagging studies have been instrumental in providing parameters for functional models. Because of their popularity, ease of manipulation and well known biology, butterflies have become model in studies of spatial structure. Yet, most studies on butterflies movement have focused on temperate species that live in open habitats, in which forest patches are barrier to movement. This study aimed to view and review data from mark-recapture as a network in two species of butterfly (Heliconius erato and Heliconius melpomene). A work of marking and recapture of the species was carried out in an Atlantic forest reserve located about 20km from the city of Natal (RN). Mark recapture studies were conducted in 3 weekly visits during January-February and July-August in 2007 and 2008. Captures were more common in two sections of the dirt road, with minimal collection in the forest trail. The spatial spread of captures was similar in the two species. Yet, distances between recaptures seem to be greater for Heliconius erato than for Heliconius melpomene. In addition, the erato network is more disconnected, suggesting that this specie has shorter traveling patches. Moving on to the network, both species have similar number of links (N) and unweighed vertices (L). However, melpomene has a weighed network 50% more connections than erato. These network metrics suggest that erato has more compartmentalized network and restricted movement than melpomene. Thus, erato has a larger number of disconnected components, nC, in the network, and a smaller network diameter. The frequency distribution of network connectivity for both species was better explained by a Power-law than by a random, Poissom distribution, showing that the Power-law provides a better fit than the Poisson for both species. Moreover, the Powerlaw erato is much better adjusted than in melpomene, which should be linked to the small movements that erato makes in the network

Dípteros (Culicidae) transmissores de arbovírus em área de proteção ambiental urbana (Parque das Dunas Natal-RN,) 2004-2006

Desenvolvido no Parque das Dunas, segunda reserva ambiental urbana do Brasil, ocupando uma área de 1.172,80 hectares, com característica de mata atlântica de dunas, situada numa faixa litorânea na região urbana do município de Natal (05° 46 S, 35º 12 W), o presente estudo, realizado durante os anos de 2004 a 2006, teve como objetivo identificar as espécies de culicídeos existentes no Parque das Dunas, capazes de transmitir arbovírus, tendo em vista que em 2004 houve uma epizootia de saguis (Callitrix jacchus), que causou grande mortandade, sem definição do agente etiológico. No ano de 2004, foram pesquisados sete pontos no interior da mata, com instalação de 20 armadilhas de ovitrampas e 20 de bambu para coleta dos imaturos. Para os adultos, durante quatro vezes por semana, foram usadas as armadilhas de Sannhon. Foram coletados 5.691 imaturos, sendo 839 Ae. aegypti, 3.184 Ae. albopictus e 1.668 Hg. leucocelaenus. A coleta dos adultos foi realizada de 2004 a 2006, etapa em que se recolheu 17.506 culicídeos adultos, sendo 17.244 Wy. bourrouli, 255 Ae. aegypti, 593 Ae. albopictus, 1.275 Hg. leucocelaenus, 294 Oc. scapularis, 05 Oc. taeniorynchus, 02 Oc. serratus e 3 Li. durhami. Para os imaturos houve correlação significativa entre Ae. aegypti e umidade relativa do ar p = 0, 049 e pluviometria p = 0,00, Ae. albopictus apresentou correlação significativa positiva com a pluviometria, enquanto Hg. leucocelaenus não apresentou nenhuma das variáveis climáticas. Para os adultos, a análise de série temporal aponta flutuação sazonal significativa para Ae. aegypti (p = 0,003); Ae. albopictus (p = 0,04); Oc. scapularis (p = 0,008 ) e Hg. leucocelaenus (p = 0,003). Uma correlação significativa negativa foi observada entre o número de Ae. albopictus coletado e a temperatura (Corr= - 0,50, p = 0,01); isto é, para cada 1°C a mais há diminuição de 7 espécimes. Este estudo teve a participação de uma equipe multidisciplinar: biólogos, entomologistas, para confirmação das espécies; técnicos de laboratório, para acompanhamento diário das larvas eclodidas das armadilhas de ovitrampas. Teve a importante colaboração de profissionais da Fundação Oswaldo Cruz FIOCRUZ/Rio de Janeiro, da Universidade de São Paulo USP para identificação do grupo Wyeomyia.

Religião e cultura local: estudo de dois grupos espíritas potiguares

The subject of this research is the spiritual religious field, connected with the local cultural perspectives. Its basis is the analysis of two spiritual groups settled in Natal/RN: The Spiritual Group Evangelho no Lar and the Spiritual Center Garimpeiros da Luz . These two groups represent a point of convergence of several sectors of this religion, either through its insertion in the local sphere or in contact to nationally influent leaders, like the mediums Francisco Cândido Xavier and Divaldo Pereira Franco. Then, it aims to reach the potiguar singularities in their spiritualism approaches, looking for an analyses to possible connections between local values and themes from the spiritualism largely developed in Brazil. So, its objective is to act in the scope of influence, references, representations and adaptive practices in a local context, and they signalize special practices . The approaches until now developed refer only to the living of a Brazilian spiritualism, perfectly developed in contact with the catholic substrate, but there s still a gap about the local observation, with its peculiarities, which its research aims to disclosure. The option for a qualitative approach, in perfect relationship with the nature of the questions which were made was considered as an appropriate way to guide the study. To reach this, it will be made an ethnography of the studied groups, not only in the use of open interviews with its members but also in the contact and observation of its religious behavior, for example: meeting for studies of the doctrine, mediunic meetings, public lectures, helping the public in general. As results of this research we can point to the delimitation of local cultural references, which are undeniable, in relation to the identification of RN personalities who are considered coordinators or active spirits in the work performed by the groups. Thus, Auta de Souza, poetess and woman of great religiosity, Augusto Severo de Albuquerque Maranhão, martyr of the aeronautics, Father João Maria, object of popular devotion and Abdias Antônio de Oliveira, ex president of the Spiritual Federation of RN, present themselves as spiritual beings who lead the adaptability to the local context. In such a context, we have to point out the work of mediums, who, having a specific charisma, interacted with the groups in the establishment of these cultural bridges already made in their own contexts (national level), through the work equally possible to be locally reproduced. This and other facts, point out to perspectives of cultural circularity , including referring to a greater linking to sub layers in a true zone that converges and has circulation between an erudite spiritualism with another one, turned to the incorporation of local and popular elements

A etnopoética de Iracema: diálogo, ciência e literatura

Literary works are thought provokers that make it possible to access several forms to view the world and reality. They provide diversified points of view and infinite connections. In a particular way, among all the other forms of art expression literature is considered to be the closest to life, once it is able to reconnect all human dimensions emotional, rational, mystic, personal, universal, corporal, historic, mythical. This thesis aims at offering some reflections about the frontiers and bridges between science and literature aiming at understanding the complexity that guides them. It presents a new reading of Iracema novel: Ceará tale of José de Alencar from a meticulous incursion through new ways and natural spaces interwoven by Alencar. It tries to hear the echoes of this indianist novel in the university students today. In a broader context, it creates arguments that question the multiple threadsthat join science and literature so that a science of complexity arises distinguishing but not separating the innumerous narratives about the world. For this purpose, this thesis has as interlocutors: Antonio Candido, Charles P. Snow, Edgar Morin, Emilio Ciurana, Fritjof Capra, George Steiner, Ilya Prigogine, Isabelle Stengers, Roger Chartier, Roland Barthes. The plot presented here does not limit the novel to science, but makes it a rereading of the word, of life, once this is the raw material of books. As a methodological strategy, we rebuilt Iracema´s character trips in a way to update the novel, resulting in the video documentary Iracema ways: the arid and remote interior, the plateau, the sea. Iracema novel and character enhancing dialogs that allow the dichotomy rupture between two cultures (Charles P. Snow), recognizing they are not incommunicable and revealing the core argument of the thesis: Iracema belongs to a complex category. It is a hybrid novel that is far, far away from that bluish plateau in the horizon

Desenvolvimento Urbano e Cidades Inclusivas: Estudo Analítico do Princípio Constitucional da Função Social das Cidades

The reality of Latin America points out that the industrialization and urbanization are complementary processes associated each other. Thus, by consequence of the demographic growth, observes the aggravation of an urbanization completely disordered and without infrastructure capable of guaranteeing rights and basic services to the population. In parallel, the dissemination of information, the valorization of human dignity, promoted by social welfare, and expectations of consumption aggravates the tensions among social actors, leading to the Theory of the Right to Development to worry about the (re)construction of cities. Before this reality, the Federal Constitution of 1988 proposed a participatory urban policy, grounded in the ideal of confrontation of social exclusion of a more comprehensive, represented by the principle of the social function of cities, which must be stratified into four inclusion´s central axes, namely: the social in the strict sense, the economic, the cultural and the policy. The Analysis of each of these dimensions, keeping the focus on reality and the Brazilian legal system, composes specific objectives of this work. Thus, through deductive research, with use of technique bibliographical and interdisciplinary, this dissertation aims to make connections between social function and development, proposing an analytical concept for the proposing an analytical concept for the principle of social function of cities, through the study of its basic elements. With this, purports to demonstrate how results, firstly, that the juridical study, to fully understand the process of marginalization, must maintain multidisciplinary perspective, own social sciences. Also aims to demonstrate that the dimensions of inclusion are formed by fundamental rights, individual and collective, of liberties and of social guarantees and that without respect to all of them there is no way to talk about implementation of urban development and nor, consequently, about inclusive cities. At the end, after checking the main legal instruments of urban policy that emphasize the community participation, provided for in the Statute of the Cities, and that potentiate the breakup of the circles of exclusion, the work want contribute to the clarification and the awaken to the importance of a new perspective democratic of development in the country, grounded in the appreciation of the individual for realization of modern management, decentralized and that, therefore, inserts the effective participation of urban communities in the acting of the State

Vitrine das letras: o discurso jornalístico e a modernidade pedagógica em Sergipe/Brasil e Portugal - (1910-1920)

Dans cette étude, j'ai eu comme objectif d'établir les connexions et/ou les non-connexions dans les discours journalistiques sur la modernité pédagogique, dans les journaux O Correio de Aracaju (Le Courrier d'Aracaju, Sergipe, Brésil) et O Século (Le Siècle, Portugal), dans la période 1910-1920. J'ai tout particulièrement cherché le dit dans les journaux, dans le sens foucaldien du terme, en continu dialogue avec d'autres auteurs, dans une perspective interdisciplinaire. J'ai tenté de répondre à mon interrogation initiale : quelles sont les connexions et non connexions que l'on pourrait établir entre l'École Moderne du Portugal et celle de Sergipe, au Brésil, en prenant comme source d'analyse les discours journalistiques dans des journaux des deux pays ? Á partir de ce questionnement, à travers un abordage historico-comparatif interculturel, j'ai soutenu la THÈSE que les discours journalistiques du Século et du Correio de Aracaju, bien qu'ils relèvent de genres journalistiques différents quant au niveau de développement de la presse, ont traduit une perception et une assimilation de la modernité pédagogique articulées à une même epistémè. Ainsi, ces discours ont émergé comme objets métis, dont la création s'est faite dans des interlocutions, échanges, impositions et débats dans un processus continu de communication interculturelle. La nature messianique de ces discours, dans le système d'idées républicain, traduisait le sens de la modernité pédagogique prétendue et diffusée par les textes qui exprimaient l'aspiration de rupture et de progrès, tant au Portugal que dans l'état brésilien de Sergipe. Il a également été possible de faire des approximations/comparaisons entre la dispute (article d'opinion), dans le Correio de Aracaju et l'enquête (interview et reportage), dans O Século et de souligner ainsi les connexions et/ou non-connexions présentes sur le thème de la modernité pédagogique dans les discours journalistiques

Protagonismo silencioso: a presença da OPAS na formação de recursos humanos em saúde no Brasil

The aim of this study is to assess the contribution of the Pan American Health Organization (PAHO) to the field of human resources for health in Brazil. The assumption is that this organization not only influenced the development of this field, but but that it was also influenced by Brazilian institutions and by national political movements, through the interaction of its consultants with these movements. Four projects were selected, through which the contribution of PAHO was evaluated: the Program for the Strategic Preparation of Health Personnel (PPREPS), the Project for the Large Scale Formation of Middle and Low Level Personnel (Large Scale Project), the Project for Qualification in the Development of Human Resources in Health (CADRHU) and the Project for the Managerial Development of Basic Units of the National Health System (GERUS). To operacionalize the study, we used three basic complementary procedures: a bibliographic research, documental research and an interview. The time frame considered was from 1975, the year an agreement was signed between PAHO, the Ministry of Health and the Ministry of Education and Culture, establishing PPREPS. It was through this program that the first PAHO team of national human resource consultants was contracted. The period between 1975 and 1999 was marked by political and social movements that changed the course of health in the country; among these was the Movement of Sanitary Reform in Brazil, which culminated in the implementation of the National Health System (SUS). This paper shows the connections of the PAHO consultants with this movement and the implications that this had for the Program of Cooperation in the Development of Human Resources of PAHO/Brazil. It also demonstrates that as the program became contaminated by national movements of health system reorganization and of democratization of Brazilian society, it proposed, in cooperation with national institutions, an organization of determinate areas of operation of these same institutions. The manuscript further reveals that, with the Large Scale Project, the human resources program determined the pedagogical and methodological option that would be the model for various other educational projects undertaken by a number of Brazilian institutions with the technical cooperation of PAHO. And finally, the repercussions and contributions of these projects, which strengthened the the field of human resources in the public health services of the country, are identified. Data analysis was based mainly on the theories of Bourdieu, Gramsci and Freire
