A travessia do trágico no romance d A Pedra do Reino de Ariano Suassuna

The present work seeks to investigate and discuss about the Greek Tragedy s elements at Ariano Suassuna s romance called τ Romance d A Pedra do Reino e o Principe do Sangue do Vai e Volta, connecting it directly to mythic, epic, poetic, and romances aspects at his work. The romance has as the protagonist the backcountry Pedro Dinis Quaderna. Quaderna is a character which is simultaneously popular, elitist, enigmatic, naive, and an intellectual man that has a great erudition. Quaderna is a character that seeks, by using the Literature, to reestablish a Brazilian backcountry kingdom which he s supposedly the king, always trying to empathizes the Brazilian northeast region like if it was a nation apart. By impressing a national personality to the Brazilian northeast , Quaderna tries to become an epic poet just like Homer, denoting a strong influence of the Epopee. Quaderna, just like many characters of Greek Tragedy, has at his family past time a lot of tragic circumstances. These facts that ocurred to his relativos like the your uncle Pedro Sebastião Garcia Barreto s death, the disappearement of his cousin Sinésio, and the contest between the brothers Arésio and Sinésio, and others aspects, remind us remarkable influences, beyond the Epopee, of the Greek Tragedy. By reading the romance we may notice many similarities between Quaderna s trajectory and Greek Tragedy heroes. To make an analysis about the tragic aspects at Suassuna s work, we need to dialogue with many theoreticals that have written about the tragic and comparate with many parts of Suassuna s with classics character s texts of Greek Tragedy. At the following chapters we seek to provide romance s elementaries notions, as well as tragic notions, the dialogue with mythics aspects and the tragic and epic aplicability at Suassuna s work

Estudo da substituição de agregados miúdos naturais por pó de pedra em concreto de cimento portland

The sharp consumption of natural resources by the construction industry has motivated numerous studies concerning the application of waste to replace partially or fully, some materials, such as aggregates, thereby reducing the environmental impact caused by the extraction of sand and crushing process. The application of stone dust from crushing process arising as an aggregate for the production of Portland cement concrete is a viable alternative in view of the high cost of natural sands, in addition to the environmental damage which causes its operation to the environment. The stone dust has reduced cost compared to natural sand because it is produced in the beds of their own quarries, which are usually located close to major urban centers. This study examined the feasibility of using stone dust from the crushing of rock gneisses in the state of Bahia, replacing natural quartz sand. In the development of scientific study was conducted to characterize physical and chemical raw materials applied and molded cylindrical specimens , using as reference values Fck 20, Fck 25 and Fck 30 MPa ( resistance characteristic of the concrete after 28 days) in following compositions stone powder: 10%, 30%, 50 %, 100% and 100% with additive. The specimens were cured and subjected to the tests of compressive strength and water absorption, then the samples were subjected to the tests of X-ray diffraction and scanning electron microscopy. The results obtained showed that the composition with 10% stone powder showed the best results regarding the physical and mechanical tests performed, confirming the reduction in compressive strength and increased water uptake increased as the content of the powder stone in the concrete composition

Influência da substituição de areia natural por pó de pedra no comportamento mecânico, microestrutural e eletroquímico de concretos

The construction industry is one of the largest consumers of natural raw materials, and concrete is considered today the most used material wide. This accentuated consumption of natural resources has generated concern with the preservation of the environment, and has motivated various studies related to the use of resid ues, which can partially or entirely substitute, with satisfactory performance, some materials such as the aggregate, and in so doing, decrease the impact on the environment caused by the produced residues. Research has been done to better understand and improve the microstructure of concrete, as well as to understand the mechanism of corrosion in reinforced steel. In this context, this work was developed aiming at discovering the influence of the substitution of natural sand by artificial sand, with rega rd to mechanical resistance, microstructure, and durability. To obtain the electrochemical parameters, an adaptation was made to the galvanostatic electrochemical method to study the corrosion in reinforced steel. Concretes of categories 20 MPa and 40 MPa were produced, containing natural sand, and concretes of the same categories were produced with artificial sand substituting the natural sand, and with the addition of sodium nitrate and sodium chloride. Due to the use of rock dust reject (artificial sand), an evaluation was made of its environmental risk. The results indicate that the concretes of category 20 MPa present a better performance than the concrete made with natural sand, thus making it a viable substitute. For the category 40 MPa, the better performance is from the concrete containing natural sand. The adaptation of the galvanostatic electrochemical technique to the study of the corrosion of reinforced steel within concrete proved to be valid for obtaining electrochemical parameters with a high degree of reliability, considering the number of degrees of freedom

Da Pedra do Rosário ao Pantanal: Espaço e Urbanização no Passo da Pátria (Natal/RN)

The Passo da Pátria is one of the areas of housing in the city of Natal/RN, presents characteristics of insecurity on ways to live and access to goods and services. The project of urbanization called Integrated Project Passo da Pátria implemented since 2002 by the public power wants to change this picture. In Passo da Pátria system of classifications of space operated by the villagers signals to singularities that allows the identification of four pieces: Pedra do Rosário , Passo , Areado and Pantanal . The actions of the Project of Urbanization promote a new socio-space configuration. Our objective is to examine ways of appropriation of space in Passo da Pátria , built by the residents, which included their cultural practices giving symbolic meaning to the four pieces. The methodological procedures consisted of: literature review of the themes of the City, Urban, Segregation socio-space, Space, the Public Policies in urban area and texts on the Passo da Pátria ; desk research and interviews with old residents, recent residents, and these: men, women, young, and leaders of the Passo da Pátria . The evaluation of the data indicates that residents live positively the action of the public power as regards the expansion of urban infrastructure and services. At the same time, negative value of the shares removal of residents and idea of integration for the different pieces that form the Passo da Pátria , for them, these actions desconstroem times, experiences and narratives that are expressed in their relations with the space in which live

Nova centralidade em Mossoró (RN): expansão urbana e o bairro Bela Vista

This research aims to reconstruct the process of the recent expansion of the urban area of Mossoró (RN), particularly the dynamics of the Bela Vista neighborhood has been established as a new urban centrality. We start from the perspective that the process of urbanization as a result of the transformation of the capitalist system have profound impacts on the restructuring of urban space, which includes resetting and training of new urban centralities. The basic assumption accepts that recent economic changes have led to the adoption of new strategies for the location of large commercial equipment and services, contributing to urban expansion and redefinition of its centrality, leading to the formation of new urban centralities. The research strategy adopted consists of a case study oriented based on the analysis of qualitative information, but also incorporates quantitative information. Interviews with qualified informants were conducted, as well as field surveys, photographic documentation, in order to grasp the phenomenon observed. The survey results show that the Bela Vista neighborhood can be considered a new urban center, housing the specialized trade and service activities, as well as townhouses, which differentiates it from other areas of the city

(Por) entre pedra e tela: a construção de uma memória republicana (Natal - 1906-1919)

This work, from a perspective that thinks the space as a historical category, and especially as a relationship which stresses the role of objects, proposes an analysis of the construction of a Republican memory in the city of Natal in the early twentieth century. This research will focus mainly on two objects: the obelisk opened in 1917, and the Andre de Albuquerque Square on the occasion of the celebration of Frei Miguelinho´s death centenary and the paint Julgamento de Frei Miguelinho ordered by the State Government to the painter Antonio Parreiras, picture that was in the Salão Nobre do Palácio do Poder Executivo of that time. In a geral way this work intend to analyse the construction of this memory as well as the role of these objects in this process. To achieve that, we propose to trace ways and networks to follow the possible associations(between people, events, images, discourses, objects, institutios etc.) in the constitution of mutual belongings. Thus, our procedure was to follow these objects through the pathways in which they became possible, so that in the end we could defend the idea that they are active participants of the process that establish them.

Nevertheless, there are deficiencies in coming with conditionality and from the use of resources the by families users

Feira livre e circuitos da economia urbana: um estudo da feira da Pedra, em São Bento (PB)

The Feira da Pedra is an extension of the open fair of São Bento in the State of Paraiba. It is a system of trade in textile goods produced by textile industry in manufacturing of hammocks and derivatives of this industry, present in some cities in the state of Paraiba and Rio Grande do Norte, as a survival strategy, inserted in the list of tertiary and retail of the urban economics of this city. It is thereby aimed to discuss about the urban economics, reflecting on the open fair system from the two circuits of urban economy, mainly in the context of the dynamics of the current period of geographic space, the technical-scientific-informational period, as the specific empirical object, the Feira da Pedra of São Bento (PB). For this, this research was carried out in two stages of operation: a) surveys of secondary data and b) primary data collection which were reported an operational triad: I) literature; II) documentary research, and III) research of field. The presence of the Feira da Pedra in São Bento has shown us one of the most important characteristics of this city, in order to present major economic, social and cultural benefits to the local population, and contribute to (re) production of sertanejo space, making lower part of the circuit of its urban economy. This activity has entailed several dynamics for urban space in this city, mainly because of attracting large numbers of people, carrying typical actions of its relationship with the urban space are são-bentense and built environment. Thus, its importance is not only a local and regional phenomenon, but also a cultural reference of a place in the geographical area of many paraibanos and norte-rio-grandenses subjects, as the case of this activity has brought to its weekly routine, this product resulting from the textile working of this area of Sertão Paraibano and Seridó Potiguar

Parque Estadual da Pedra da Boca (Araruna/PB): uma avaliação sobre as atividades turísticas e as ações de gestão territorial

The Conservation Units, specially the National and State parks are among the major destinations for adventure tourism and ecotourism, so that the National System of Unit Conservation (Sistema Nacional de Unidades de Conservação) SNUC (Law 9.985/2000) covers the practice of touristic activities, specially the ecotourism in these territorial unities. Despite these are areas for environmental conservation, practice of environmental education, scientific research and contemplation of the nature in its primary or in a similar condition, the practice of touristic activity does not often meet these aims. The main aim of this research was to evaluate the touristic activities and the actions of territorial management in the State Park of Pedra da Boca (PEPB), situated in the city of Araruna/PB. According to the results, the PEPB has in its territorial area a porphyritic granite rock set, whose geological and geomorphologic settings are unique and have scenic value. It is also home of flora and fauna endemic species and representative of the savanna biome. The data and information achieved show that the Park has a remarkable potential for tourism, especially ecotourism, however, there is a need for development of territorial management actions, in order to subsidize the use of spatial tourism site

O erro produzido pelo aluno no contexto pedagógico: uma luz ou uma pedra no meio do caminho?

Student’s mistakes as viewed in a didactic and pedagogical perspective are a phenomenon inevitably observed in any context in which formal teaching-andlearning processes are taking place. Researchers have shown that such mistakes are viewed most of the times as undesirable and often as a consequence of lack of attention or poor commitment on the part of the student and rarely considered didactically useful. The object of our reflections in this work is exactly those mistakes, which are born in the entrails of the teaching-and-learning processes. It is our understanding that a mistake constitutes a tool which mediates knowledge and may therefore become a strong ally of the instructor’s actions in her/his teaching tasks and thus should be taken into the teacher’s best consideration. Understanding a mistake as so, we postulate that the teacher must face it as a possibility to be exploited rather than as a negative occurrence. Such an attitude on the part of the teacher would undoubtedly render profitable didactic situations. To deepen the understanding of our aim, we took a case study on the perception of senior college students in the program of Mathematics at UFRN in the year 2009, 2nd term. The reason of this choice is the fact that Mathematics is the field presenting traditionally the poorest records in terms of school grades. In this work we put forth data associated to ENEM1 , to the UFRN Vestibular2 and the undergraduate courses on Mathematics. The theoretical matrixes supporting our reflections in this thesis follow the ideas proposed by Castorina (1988); Davis e Espósito (1990); Aquino (1997); Luckesi (2006); Cury (1994; 2008); Pinto (2000); Torre (2007). To carry out the study, we applied a semi-structured questionnaire containing 14 questions, out of which 10 were open questions. The questions were methodologically based on the Thematic Analysis – One of the techniques for Content Analysis schemed by Bardin (1977) – and it was also used the computer program Modalisa 6.0 (A software designed by faculties the University of Paris VIII). The results indicate that most of the teachers training instructors in their pedagogical practice view the mistakes made by their students only as a guide for grading and, in this procedure, the student is frequently labeled as guilty. Conclusive analyses, therefore, signal to the necessity of orienting the teachers training instructors in the sense of building a new theoretical contemplation of the students’ mistakes and their pedagogical potentialities and so making those professionals perceive the importance of such mistakes, since they reveal gaps in the process of learning and provide valuable avenues for the teaching procedures.

Avaliação do efeito da adição de resíduo de borracha de pneu e brita calcária na formulação de compósitos cimentíceos

Researches have shown that the introduction of rubber in concrete improves the features of its deformability, as well as contributes to environmental disposal of waste generated in the tire retreading process. Furthermore, there is a high availability of limestone within RN and CE country. Ignorance about this stone, does not allow its wide use as aggregate, leaving, this abundant supply idle. A composite of limestone gravel, with proportions of tire rubber waste which could be used as concrete would be an alternative to concrete for low applications. Therefore, this research aims to evaluate the characteristics of concrete containing limestone gravel and proportions of little aggregate replacement (sand) by tire rubber waste. To this goal, the material components of the concrete were characterized, concrete specimens with limestone gravel were made, from the dash 1.0: 2.5: 3.5, varying the water/cement ratio, and inserting a commercial plasticizer, without a proportion of residue, known as reference. From this, concrete with and without the presence of the additive in the same proportions were chosen, as well as these with the use of granite gravel, for being the most used. Selected the references, to these, replacements of little aggregate (sand) were added replaced by rubber waste from the tire retreading process, treated with 1M NaOH in proportions from 5.0 to 20.0 % by mass, cured and exposed to the semiarid environment. The results indicate the possibility of using limestone gravel in the concrete composition with workability correction using plasticizer. There was a decrease in the mechanical properties of the concrete with increments of waste rubber, but there is an improvement in toughness and deformability of the composite, which makes it interesting for the construction of non-structural concrete floors, as well as, the rubber waste delayed the hardening process, continuing to gain resistance after 28 days
