Areia sob os pés da alma: uma leitura da vida e obra de Oswaldo Lamartine de Faria

This study followed the development of Oswaldo Lamartine de Faria as an intellectual, with the aim of establishing the emergence of that de Faria’s work under the umbrella of the sertão (hinterland) in Northeast Brazil. It accompanied the emergence of the researcher, his discovery of his mission to study the sertão in Seridó and the vital importance of his relationship with Luís da Câmara Cascudo, since despite being a natural born observer, Oswaldo Lamartine embarked on a career as a researcher after encouragement by Cascudo. The first chapter of this study, denominated The Gates of Time, portrays the country during the drought of 1919, the year Lamartine was born. It describes his childhood and first encounters with Câmara Cascudo; his urban exile in Rio de Janeiro; the books written by the young Oswaldo, those that came later, and his definitive return to the state of Rio Grande do Norte. The following two chapters, Sand beneath the Feet of the Soul and Images of a Nobleman from the Sertão, summarize Lamartine’s books and describe his entry into the canon of the state’s culture, with particular prominence given to his interview for the documentary “Oswaldo Lamartine: prince of the sertão”, highlighting his attempt (through his writing) to preserve his own existence. In the second section, Verses, Bold, Between the Lines features analyses of texts dedicated to Oswaldo Lamartine, such as those written by de Zila Mamede, Maria Lúcia Dal Farra and Paulo de Tarso Correia de Melo. The next chapter, entitled Warm and Vivid Ashes, highlights Lamartine’s correspondence with Luís da Câmara Cascudo and the incredible friendship between the two researchers. Cascudo’s letters are analyzed through the book De Cascudo para Oswaldo (From Cascudo to Oswaldo) and and are a powerful testimony of Oswaldo Lamartine’s permanent connection to Rio Grande do Norte. In conclusion, the final chapter entitled Combine, Tattoo, Imprint analyzes the writer’s five-book collection entitled Sertões do Seridó (Hinterlands of Seridó). In reading each of these, it becomes clear that observing reality was vital to the writer’s work. This is one of the first studies to be conducted about Oswaldo Lamartine at the Federal University of Rio Grande do Norte and its main theoretical references were the reflections of authors Jacques Le Goff (2003), Lejeune (1994; 2008), Maurice Blanchot (1987; 2005), Alfredo Bosi (1987) and Gaston Bachelard (n.d.).

O nascimento de uma política pública: das articulações à formulação do PRONERA

This work aims at reconstructing the formulation process of PRONERA (National Program of Education in Agrarian Reform). A public policy that had its first ideas conceived within social movements and afterwards, made possible by diligences of then government. Therefore, the Program was rendered in a partnership among State, social movement, public institutions, and non-governmental organizations. As a goal, we intend to grasp both what motivated the choice for this proposal as a strategy to face educational problems in rural areas and how the actors, entities involved in this enterprise and the social-political context have influenced its formulation and entry in the governmental agenda as Public Policy. Thus, we reconstruct the history and education policy of and in rural areas. Besides, we seek to understand the context of PRONERA's conception, the factors that have influenced its creation and the actors' performances in the process. It is assumed that under the 1988 Constitution, civil society was provided with legal conditions for the active participation in political process and, consequently, in the public policy-making. We conclude, then, that PRONERA was the result of the crossing of three different flows (problems, solutions and policies) advocated by the Kingdon model. As a result, this analytical repertoire was useful to explain PRONERA’s entry in the government agenda, helping to understand how the chances of this social demand increased with an action from the politic community. It allowed its way in the government agenda as well as its becoming a public policy.

A releitura de um documento: o processo de tombamento do centro histórico de Natal (RN)

During over seven decades of institutionalizing the national heritage protection legal instrument it can be noticed the many ways of the instrument application, according to the approaches that were assigned to the spaces with heritage values and the dynamic of the elaborated thoughts within this theme. For the application of the instrument effectively, there is a long process that is carried out. This process begins with the study elaboration that aims to subsidize and justify the motivation of property protection, as well as the proposal of buffer zones and national protection areas delimitations, completing the process with the denial of the request or with the publication of the definitive national protection area at the Official Gazette. Starting with the relation between the existing heritage values identification into the historical centres and the definition of its protection areas that the area management will be done, based as well into the management intervention norms established for the protection area perimeter. From this context, the present essay has as porpoise to discuss the approach used for the identification and selection of a historical centre liable for national protection and the repercussion of this identification into the national protection area the was established, using a case study of the national protection of the historical centre of the city of Natal. Starting from the assumption that there are inconsistences and distortions about the text speech of the written document and the spatial delimitation of this document, motivated by an area that privileges the edifications rather than the urban space. Beginning with the urban history methodology, we are based on the precepts of Rossi (2011), Lamas (2010) and Cullen (2009) for that space reading, along with what Sant’Anna (2004) defines as “city-document” to make a new reading of this “heritage value space” verifying if the proposed protection area reflects what is defined as motivation for the national protection area process during the recognizing process. Therefore, it is concluded that it is essential that the buffer zones and the national protection areas are aligned with the text presented at the national protection area instruction, so the norms and criteria definition management process are established. We highlight that a site management and the identified values protection become very difficult without a specific law that beacon the decisions that should be taken.

Otimização de parâmetros mecânicos e microestruturais dos moldes em areia de sílica ligados quimicamente pelo processo de cura a frio em fundição de aço

Surface defects on steel parts borne costs of smelting industries due to the need of rework. Sand molds are frequently used in foundry industries and largely responsible for providing surface defects. This study aims to optimize the levels of the molding process variables to minimize the occurrence of surface defects in steel castings in silica sand molds chemically linked by cold cure process. The methodology used the experimental design with split plot, being considered in the study the resin percentage factors in the mold formulation, addition of iron oxide, type of paint, the paint application method, amount of ink layers, use of hot air along the lines and waiting time of the mold before casting. They were analyzed as response variables erosion defects, sand inclusion, penetration, porosity and surface finish. Tensile strength tests were performed to evaluate the influence of factors on mechanical parameters and the microstructural parameters were carried out the analysis of X-ray diffraction, scanning electron microscopy (SEM) and thermal analysis (TG / DSC / dilatometry). The results elucidate that for the faulty erosion, the only significant factor with a 95% confidence level was the type of ink and the ink alumina-based superior results obtained. For the sand inclusion of defect, there were three significant factors, with best results obtained with alumina-based paint and spray applied using hot air in the mold before casting the metal. For the defect penetration, there were four significant factors, the best results being achieved with 0.8% of resin and addition of iron oxide in the molding formulation, the paint being applied by brush and standby time of 24 hours before leak. For the defect porosity with a 95% confidence level, no significant factors. For the defect surface finish, the best results were achieved with the 0.8% formulation of the resin in the mold and application of the paint brush. To obtain the levels of the factors that optimize all defects simultaneously, we performed a weighted average of the results of each type of fault, concluding that the best levels of the factors were: 0.8% resin and addition of iron oxide in the formulation of the template, application of two coats of paint applied with a brush or spray, using hot air in the mold before casting and 24 hours of waiting ready the mold before casting. These levels of the optimized factors were used in an experiment to confirm that ratified the results, helping to reduce rework and consequently reducing costs of cast steel parts.

Processo identitário e saberes docentes: um estudo a partir da prática de ensino no estágio do curso de pedagogia da UFRN

Esta investigación parte del interés en la comprensión de la cuestión de los conocimientos enseñanza, precisamente el conocimiento necesario para el profesor profesional relacionada enseñanza, es decir, cuáles son los conocimientos, los profesores a construir en su contexto de trabajo. Somos conscientes de que el escenario es un momento de importancia fundamental para el desarrollo del conocimiento inicial de la profesión docente y la construcción de la identidad profesional. Tratando de entender estos aspectos nos preguntamos: ¿Qué conocimientos de los futuros profesores construyen o se movilizan durante la práctica docente desarrollado en el escenario? Nuestro objetivo es entender el proceso de identidad de estudiantes Pedagogía UFRN e identificar el conocimiento construido sobre la práctica docente desarrollada durante el entrenamiento supervisado de dicho curso. Se trata de una investigación cualitativa, y tenía como instrumento de recolección de datos, entrevistas semi-estructuradas con diez (10) en 2014.1 académicos que habían ocupado la práctica docente en el entrenamiento supervisado. Las entrevistas fueron sometidas a análisis de contenido propuesto por Bardin (2011). Como marco teórico, los autores también apoyan en tan Tardif (2012), Pimenta (2012), Nóvoa (1995), Perrenoud (2002), entre otros, se trata de la enseñanza de conocimientos dentro de la profesionalización docente, estableciendo relación con el proceso de identidad. Los resultados indican que, en lo que respecta a la identidad profesional, estudios teóricos en el curso de formación inicial, junto con las experiencias vividas en su mayoría en el escenario, contribuyeron a cambiar lo que los estudiantes sabían acerca de ser un maestro. Por lo tanto, algunos han fortalecido la identidad con la profesión, mientras que otros han renunciado a invertir en la carrera docente. En cuanto a conocimiento construido, se puede decir que los alumnos se dan cuenta de la pluralidad de conocimientos necesarios para una profesión tan compleja como la enseñanza. Sin embargo, a modo de síntesis, este conocimiento a su vez a aprender a planificar lecciones considerando las necesidades de los estudiantes y su contexto social. Los participantes declaran saber cómo llevar a cabo la mediación del aprendizaje a través del diálogo y actividades bien estructuradas y afecto contribuye al aprendizaje. En este sentido, se entiende que las construcciones de conocimiento en el escenario se articularon a reflexionar sobre su propia práctica e indican lo que era más importante en términos de aprendizaje de la percepción de los estudiantes. Sobre la base de este entendimiento, creemos que los momentos de observación (primero paso en el escenario) y el muy regencia podrían considerarse en el proceso de formación, para que los estudiantes se registre el aprendizaje proporcionado por la práctica. Es necesario, por tanto, que los estudiantes investiguen su propia actividad pedagógica, convirtiendo sus conocimientos en una continua construcción y reconstrucción de sus identidades a partir de la importancia social que conceden a la enseñanza.

A produção textual no ensino fundamental: processo de retextualização com o gênero memórias

Teaching Portuguese language in Brazilian public schools is still limited mostly to studying decontextualized text fragments, memorizing classifications and cult of grammar rules. Considering the language as a social, cultural practice which emerges from the intersubjective interaction, we sought to propose an educational intervention that prioritizes the retextualization processes from speech to the writing of memoirs as a textual genre, so as to contribute for improving learner’s discursive performances. Therefore, paying attention to these concerns and in attempt to contribute for improving the teaching of Portuguese language in elementary school, we chose as privileged locus a 9th grade class from a state school in Bento Fernandes, RN. The corpus is formed by texts produced and retextualized by students from the elders’ oral reports within local community. We sought thus to understand what memory is, its importance for registering local spoken language and culture, as much as to carry out didactic actions that favor students’ learning in the activities of textual production. In light of the theoretical overviews about linguistic-discursive relations, based on Marcuschi’s (1993, 1997, 2001, 2002, 2006, 2008, 2010) conception of oralitiy-writing continuum and the debates proposed by Antunes (2003, 2014), Alves Filho (2011), Koch (2012) and Bakhtin (1992, 2011), we aimed to understand, by analyzing the retextualized memoirs, how these practices complement each other within the process of orality and writing. As for the proposal of didactic sequences, the study has been oriented by Dolz and Scheneuely (2004); as for the memoirs, by the guidelines of Coracine and Ghiraldelo (2011) and Le Goff (2010, 2013). In this way, this work followed the action-research methodology in a qualitative approach, considering the teacher (researcher) as an active agent involved in the process of knowledge production in his own educational practice, so as to interfere in the mediation, knowledge production and its dissemination in classroom context, which is the privileged locus for constructing and transforming process. There is much to be research within the area of retextualization. Yet we verified that this educational intervention, based on discursive operators of retextualization, has been proven viable as an efficient path so that we teachers can work the peculiarities of usages and functions of textual genres in oral and written modalities of a language, without grasping both as a dichotomy. This accredited us to strengthen a discourse that undoes many myths still present in that order, especially the one that causes more damage for the learners of Portuguese language – that writing is a representation of speech.

Avaliação ambiental de manguezais adjacentes aos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

Among the various effects caused by the climate change and human intervention, the mangrove ecosystem changes through of the years has been worth mentioning, which hasn t known which are the pros and cons for the adjacent coastal and estuarine environments yet. It happens due to the present dynamism in these areas, besides of the difficult understanding of the processes associated with evolution. This study aimed to environmentally evaluate adjacent mangroves from the Macau and Serra oil fields, located on Rio Grande do Norte northern coast, to support the mitigating actions related to the containment of the erosive process, as well as, according to the principles of the Clean Development Mechanism (CDM), to assess the amount of atmospheric carbon sequestered by the studied ecosystem. An inventory was conducted through mangrouve mapping which has supplied this research, especially regarding to the structural characterization of mangrove areas. To understand the local mangrove behavior in a greater level detail, techniques of remote sensing, GIS and GPS were used to make an analogy between the current and past states of the mangrove studied, allowing to make anticipated projections for the future impacts or changes in that region. This study combined data from multispectral LANDSAT 5 TM, Landsat 7 ETM+ with radar microwave data from SAR RADARSAT-1, which increased the interpretation capacity of the data from optical sensor systems. The interpretations have been supported by the data field, representing a better and innovative methodology for the environmental and taxonomic characterization of mangrove forests considered. The results reveal that mangroves of the Ponta do Tubarão Sustainable Development Reserve are biologically representative areas and providing a variety of benefits, especially for local communities, constituting the priority sites for actions development aimed at conservation. They also have been showing the necessity to make mitigating measures in order to recover degraded areas through reforestation or creating new areas of mangrove, as currently 7.1% of the mangrove forests studied are dead or in an advanced state of decomposition. The amount of atmospheric carbon sequestered proved very significant when analyzed for the whole area, which is able to sequester atmospheric 4,294,458 Ton CO2 per year

Estudo do processo de drenagem gravitacional do óleo assistido com injeção de vapor e solvente

Como os recursos de hidrocarbonetos convencionais estão se esgotando, a crescente demanda mundial por energia impulsiona a indústria do petróleo para desenvolver mais reservatórios não convencionais. Os recursos mundiais de betume e óleo pesado são estimados em 5,6 trilhões de barris, dos quais 80% estão localizados na Venezuela, Canadá e EUA. Um dos métodos para explorar estes hidrocarbonetos é o processo de drenagem gravitacional assistido com injeção de vapor e solvente (ES-SAGD Expanding Solvent Steam Assisted Gravity Drainage). Neste processo são utilizados dois poços horizontais paralelos e situados verticalmente um acima do outro, um produtor na base do reservatório e um injetor de vapor e solvente no topo do reservatório. Este processo é composto por um método térmico (injeção de vapor) e um método miscível (injeção de solvente) com a finalidade de causar a redução das tensões interfaciais e da viscosidade do óleo ou betume. O objetivo deste estudo é analisar a sensibilidade de alguns parâmetros operacionais, tais como: tipo de solvente injetado, qualidade do vapor, distância vertical entre os poços, porcentagem de solvente injetado e vazão de injeção de vapor sobre o fator de recuperação para 5, 10 e 15 anos. Os estudos foram realizados através de simulações concretizadas no módulo STARS (Steam Thermal, and Advanced Processes Reservoir Simulator) do programa da CMG (Computer Modelling Group), versão 2010.10, onde as interações entre os parâmetros operacionais, estudados em um modelo homogêneo com características de reservatórios semelhantes aos encontrados no Nordeste Brasileiro, foram observadas. Os resultados obtidos neste estudo mostraram que os melhores fatores de recuperação ocorreram para níveis máximos do percentual de solvente injetado e da distância vertical entre os poços. Observou-se também que o processo será rentável dependendo do tipo e do valor do solvente injetado
