Estudo da hidrodinâmica de um novo separador líquido-líquido: aplicação ao sistema óleo-bruto/água produzida

This work aims to use a different hydrodynamic condition applied to a new design of mixer-settler on treating wastewater produced by petroleum industry, called MDIF (Misturador-Decantador à Inversão de Fases/ Mixer-Settler based on Phase Inversion MSPI). The use of this different hydrodynamic behaviour is possible due to vertical disposition of the device and the principle of Phase Inversion that controls the MDIF, providing the generation (creation) of a cascade of drops, into an organic layer, that works as micro-decanters, thus making possible the formation of a bed of non-coalesced drops, called Bed Formation . The use of this new hydrodynamics condition allows to increase the residence time of the oil carrier drops, into an organic layer, and the device can treat a greater volume of wastewater. In view of to get this condition it is necessary to operate at high throughput (58,6 m3.m-2.h-1). By results, the condition of Bed Formation is the best one to be used when MSPI operates with throughput up to 58,6 m3.m-2.h-1. The results using the condition of Bed Formation show that increasing the height of the bed of non-coalesced drops and/or decreasing the volumetric ratio (O/A) an increase of the separation efficiency is detected

Model-Driven requirements engineering process aided by ontologies and natural controlled languages

Researches in Requirements Engineering have been growing in the latest few years. Researchers are concerned with a set of open issues such as: communication between several user profiles involved in software engineering; scope definition; volatility and traceability issues. To cope with these issues a set of works are concentrated in (i) defining processes to collect client s specifications in order to solve scope issues; (ii) defining models to represent requirements to address communication and traceability issues; and (iii) working on mechanisms and processes to be applied to requirements modeling in order to facilitate requirements evolution and maintenance, addressing volatility and traceability issues. We propose an iterative Model-Driven process to solve these issues, based on a double layered CIM to communicate requirements related knowledge to a wider amount of stakeholders. We also present a tool to help requirements engineer through the RE process. Finally we present a case study to illustrate the process and tool s benefits and usage

Transplantes: re-inserção social e qualidade de vida dos transplantados cardíacos do Estado do RN

The experience of transplantation is a very serious situation from the clinical standpoint. Therefore, there must be some subjective and social breakdown in people who have been undergone such a procedure. Recent product of modernity, the transplanted is someone who owns his recover to the scientific advances of contemporary society and a deceased donor. This paper aims at examine the implications, from the changes in patterns of behavior and thought that occur after the experience of an extreme and critical situation, as the process of illness and its consequent transplant surgery. The symbolism of the heart suggests that some social impressions about the organ itself are also reflected in how the transplanted interprets the experience of this type of procedure. So investigating how the changes occurred throughout the process interfere in the re-insertion of these people to social life, after his recovery, is the purpose of this work. The concept of habitus coined by Pierre Bourdieu will be used to measure conceptually how this experience (clinical, modern and symbolic) fits in the contemporary discussion of sociology

Natal como destino turístico : um estudo das imagens (re)veladas pela mídia, pelos turistas e suas implicações educacionais e culturais

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

A (re)significação conceptual nas práticas colaborativas com professores do Ensino Fundamental

The work objectified to apprehend the degree of the teachers' concept concerning the territory concept and to intervene with situations of critical reflections to accompany and to analyze the process of conceptual elaboration. It contemplates on the (new)meaning of knowledge and (new)elaboration of the concept in study done inside a pedagogic intervention. The Municipal School Dr. Julio Senna - Ceará-Mirim/RN and six (6) teacher-collaborators that taught in the 3rd and 4th grades of the fundamental teaching, constitutes the empiric field of the research. Its theoretical-methodological contributions are built in the studies of Vigotski (2000a, 2000b and 2001) on the formation process and development of concepts; in the methodology colaborate (Ibiapina (2004), Bartomé (1986), Kemmis and Mctaggart (1988), Arnal, Del Ricon and Latorre (1992), Pepper and Ghedin (2002), among others) and in the critical-reflexive conception of the Geography (Soares Júnior (2000 and 1994), Silva (1998), Raffestin (1993), Santos (1994), Felipe (1998), among others). The accomplishment of the work presupposed starting from the reflections on the following subjects: which the teachers' understanding in the school space concerning the territory concept? How does happen the process of conceptual construction territory for the teachers? The analysis of the teachers' previous knowledge on the concept in study, evidenced that its apprehensions on the attributes of the referred concept went mentioned the to light of the perceptible dimension of the real-concrete relationships of the reality linked to the degree of the spontaneous concepts and followed by the ideas of the traditional, humanistic and cultural geographical conceptions (positivism and phenomenology), restricting the territory meaning the notion of State-Nation and place of the men's dwelling. In the intervention process, it was verified to real possibility of the acquisition of indispensable scientific concepts to the process of (new)meaning conceptual of geographical knowledge through the continuous practice of the educational formation, when it was evidenced that the teacher-collaborators acquired high degrees of attributions of the significance of the territory concept to the they elaborate generalizations by means of analyses and syntheses of the concept-attribute (essential and multiples) of the reference conceptual in study

Uma ação reflexiva sobre o processo de (re)escrita de textos: a prática pedagógica da professora Maria

T he reflexive action on the process of texts (re)writing, central topic of this study, is still a challenge within the elementary school. What made this issue a special theme of study was the fact that the chosen focus is based on a lived experiences with (re) writing activities where the uniqueness of the professional practice would be transformed into a place of knowledge production, offering theoretical and a practical support to a teacher, in order to understand the interactive nature of language as a space for recovery of the individual (as a historical, social, and cultural being). The empirical field research, structured in the light of assumptions of qualitative research into the action research format, was a public school in Bahia, in a third grade classroom. The instruments of data collection were open questionnaire, semistructured interviews, observations with video recording, documentary analysis of texts produced by students, and reflective sessions. The objectives that supported the research study were: 1) Investigate, in the pedagogical action of teacher Maria, activities on the writing process, 2) Interact with the teacher, in the form of action inquiry to: a) reflect on the procedures for theoretical and methodological development of reflective practice on the process of the (re) writing of the text, b) intervene in the construction of didactic situations that enable the learning and the development of reflexive actions in the (re) writing of texts. To accomplish these goals, it was established as a commitment a dialogic communication with the protagonist, providing reflection sessions so she could examine her teaching practices. The most relevant theoretical arguments to the establishment of this research came from the theoretical and methodological approaches of Bakhtin s theory of enunciation-discourse (2003, 2004) and Vygotsky s socio-interactionist theory (1989, 1998), as it is believed that both theories, through a paradigm shift, in which the constitution of the individual and the participation of others in the actions of analysis and reflection on the language, would give opportunities for internalization and construction of knowledge. The systematic and critical pondering led the participating teacher into reviewing her teaching praxis, compelling her to promote a more insightful understanding of the writing process of her students. That experirence brought into evidence three categories of actions: 1) actions that reflect the technical rationalism, 2) actions that reflect an emancipatory metamorphosis, and 3) actions that reflect empowerment and awareness. The results confirm that the action / reflection on the process of the (re) writing of a text has a dimension of increasing levels of awareness and self criticism, reproducing other meanings for teaching praxis

A dimensão social do desenho: um estudo sobre as interações no processo de (re) construção imagética da criança no Ensino Fundamental

In the historical-cultural perspective, the drawing is processed by means of a shared and complex way, under diverse relations with the other and with the immersed signs of the culture. That is, something constituted by the social interactions and that can modify the structure of the psychological functions, therefore as socialized sign, propitiates the incorporation of the functions socially. In this way, the figuration carrier sensitive and established meanings historically disclosing the shared experiences and the ways of the subject to think and perceive the world. Such reflections gave shape to the main problem of this research: how to think over about the drawing at the school to incide in the reconstruction of the childs imaginative language? Under such perspective, this work deals with the interactions in the production process of the drawing of the children in a context of teach-Iearning of the elementary school having as goal to analyze the interactions established in the cIassroom in the process of production of the drawings; to propose situations of learnings that favor the advance graphical expression of the students; and to identify in the interactive games some relations between body expression and drawing. For its accomplishment, it was opted for the construction process based in the collaborative investigation by the fact to propitiate negotiations, sharing and confrontation of ideas, becoming possible a joint construction of the knowledge. For this research, the researcher and the collaborating teacher, as well as the involved children, become themselves into co-authors of the context studied. As locus of the research, it was chosen a first cycle class, with 30 students, from Municipal School Profª. Emília Ramos (Natal/RN - Brazil), whose election took in account the fact of this school to constitute in a promotional space of reflections and professional development of teachers in service and, at the same time, for presentinglimitations theoretic- methodological in the field of teaching for Arts. In the process of the research, it was perceived that the children with the support of the verbal language formulates meanings on the seen and imagined object, printing lines and forms that if overlap to the physiological aspects of the visual perception. That is, the drawing discloses a reality appraised, enriched for the picked up vision of the image, but the meanings established for the author, or observer who becomes it perceivable and identified. In the systemizing situations, it was observed that the teaching-Iearning process of the drawing, implies a co-construction between teachers and learners. And, moreover, the necessity to interlace emotion and cognition by means of plastic-corporal interactions that foment drawing experiences, whose process concurs for the imagenative reconstruct of the apprentices

A constituição discursiva de identidades étnicorraciais de docentes negros/as: silenciamentos, batalhas travadas e histórias (re) significadas

In this research study, in which I discuss the discursive constitution of ethnic-racial identity of black male and female teachers, I understand that the process of identity formation of the subject covers both personal/family and social/professional areas. In it, I propose, in general terms, to analyze the discursive practices present in narratives of black male and female teachers when they look for their social insertion into different social contexts, identifying outbreaks of resistance that are present in their process of ethnicracial identities. The fundamental issue that permeates the survey investigates: how can black male and female teachers behave discursively in the construction of ethnicracial identities in multiple distinct contexts? The theoretical foundations that support this research work come from theoretical fields that complement each other; among them, French Discourse Analysis, Foucault s Theory and cultural studies. These, even with their singularities, are being interlaced by the conception that conceives language as social practice. Methodologically, I adopt an interpretative and qualitative paradigm to examine not only the linguistic repertoires that compose these teachers written narratives written but also the data that were generated by semi-structured interviews. The results show that the subjects, realizing contrary forces that interfere in their process of social inclusion, make use of acetic techniques to (re)signify the history of their lives

Reestruturação da disciplina "Física I" do Curso de Tecnólogo em Gerência de Obras de Edificações do CEFET/PB

The aim of the present paper is to reorganize a discipline on technological physics so that the construction site of civil engineering becomes a natural environment of learning, providing the learner with the association between theory and practice as well as allowing the subject to process, in real time, information generated from his cognitive constructions and his contextualizations. Thus, a sequence of actions was taken into account: firstly, the programme was developed in the classroom, sharing with its contextualized information through experiments done under supervision by the learners in laboratories; secondly, the data which associate physics with construction were collected and, to do so, technical visits to construction sites were realized, providing the learner the association between the theory and the practice in a suitable site to the constructivist approach. As a result, the first discipline on physics of the Curso de Tecnólogos em Gerência de Obras de Edificações do CEFET/PB was re-structured in terms of syllabus, methodology, application and evaluation. In fact, this work deals with a dynamic process that gathers and gives emphasis to teaching, learning, technology, information, creativity, competence and abilities in a constructivist learning process and, as a consequence, having allowed institutional engagement

Projeto político de formação do enfermeiro: contextos, textos, (re)construções

This research analyses politic Project for nursing education, in its articulation with economical, political and social context of 1970s and 1980s in national level and, in special, nurse formation process in FAEN/UERN space, situating it on the context of Brazilian sanitary reformation movement and participation movement. The thesis is firmed on the sense of explaining whether that movement circa the nurse formation process has been able to build necessary instruments for the transformation of biomedical formation model historically consolidated, in the perspective of conceiving another model anchored on social determination of health/illness process, with the purpose of assuring ethical and political commitment with the SUS praised by sanitary reformation. The study visualized the object considering its specificity, its concrete historical determinations and institutional as well as organizational relationships that permeate possibilities of valorizing it, analyzing it, interpreting it and rebuilding it. Its operationalization occurred in three movements, it means, bibliographical review; documents study; interviews and focal groups realized with professors of the institution. We can apprehend as main results that the nurse formation process has incorporated widely spread conceptions by the sanitary reformation movement and participation movement, assuming the commitment with transformation of health services and social reality. Nevertheless it prevails, still, amongst some professors in the same institutional space, the commitment to a predominantly technicist formation, focused on instrumental knowledge. Opinion divergence explicit diversity of conceptions circa education and, as consequence, distinct political commitments, also contradictory to formation. Thus, there is a lacuna between what is foreseen on political pedagogical project and what is rendered in FAEN/UERN, evidencing the clash related to conceptual bases of formation project. Interpretations, divergent political attitudes and resistances to the process allowed several formation ways. However, formation under new conceptual bases, find limits on the context of social politics implemented in Brazil during the 1990s, neoliberal-based, expressed on expansion and consolidation of health private system, managed by market rules, strengthening biomedical formation model. Notwithstanding, there is a favorable to its implementation, starting from the first years of 21st century, moment when Brazilian sanitary reformation reappear on health speech, as well as facing the policy of permanent education in health. This reality explicit a process of dialectical tension between instituted and institutor, anticipating the moment of scission or adaptation and return to what is already known. Despite of clashed, knowledge, accumulated experience, contribution to services, the construction of partnerships out of university space and articulation with national movement of (re)orientation of nurse formation, have been constituted as vital instruments to offer support to formation in FAEN/UERN. Still, we consider necessary the (re)visitation to FAEN/UERN politic pedagogical Project considering the existing and implemented construction, without, yet, depreciate the norther axis of the project at the reaching of its intentionality

Shopping-centers :elementos de (re)produção urbana na zona de sul de Natal-RN

This study aims at analysing the (re) prodction of urban space in the south sone of Natal city, in particular the influence of the shopping-centers in this process. In this respect, it also analyses the changes of habits and constumes for part of the society, when those entreprizes were built in better-off areas of the south zone Natal as well as the transformations in the surroundings of the thre main shopping-centers. A sother commercial establishments of the same size, two out of the three main shopping-centers in the city are targered towards the better-off population. However, if compared to the others, one these has, for some time, sought to target a lower in come population. In spite of being an important element in the (re)production of urban space as well as in the cities modern commercial sector, these large commercial entreprizes reinforce capitalisms contradctions in so far as they constitute semi-public space whit an exclusionary and segregatory vatune

O processo de (re)produção do espaço urbano de Nova Parnamirim

The public and private politics that was implemented in Natal, have always been attracting, great contingent of people in search of employments. However, not always, they can attend the migratory demands. Recently, Nova Parnamirim that is situated in the municipal district of Parnamirim - RN, due to proximity with Natal, it is passing for an intensive and accelerated occupation process impelled by the urban politics that created and they determined new diversities, leaning in the growth of the modern tertiary. In this context, Nova Parnamirim is suffering, along the time, substantial transformations in your espace, so much of nature social as environmental, that are affecting in the quality of your residents' life. This fact is mainly linked in the absence of an appropriate urban planning that have to be considered as an instrument norteador of the development of the city in its constant construction process. The study has as objective to analyze the social-space dynamics of the area and their implications, identifying the principal agents that promote and they benefit of that urbanization process. For the ccomplishment of this research it was executed bibliographical readings that turn of theoretical studies about the urban subjects and enviroments, besides field activities for the rising of the data investigated in the methodological approach

De baixo para cima: implicações socioespaciais da transferência da feira livre na (re)produção do espaço urbano de Nova Cruz-RN (1991-2010)

The present work is about the reproduction of the urban area of Nova Cruz RN, with the objective of analyzing the social and spatial implications of the relocation of the main street market in the city from 1991 on. Nowadays, the city of Nova Cruz takes over importance in the potiguar social and spatial scenario due to its condition of central city which is practiced for decades in Potiguar Agreste Microregion. Beginning with its formation process connected with traveler‟s hostel which assisted the activity of cattle transportation, further in time by the golden era of cotton production in its territory, it was noticed that its importance in relation with the nearby towns has been happening differently throughout time. From the year 1991 on, the town of Nova Cruz has gone through a territory restructuring of its urban area due to the relocation of the open market from Downtown neighborhood to São Sebastião neighborhood. Such territorial movement resulted in a reformation of the town‟s urban space, promoting in both neighborhoods urban growth and the expansion of commercial activity associated with the migration of the commercial center of the city. The transference of the commercial area has caused these processes through the new uses of the land towards the São Sebastião region, it has also caused a decrease in market value of the downtown area as a result of the breakdown of previous existing business activities, their service contribution and the citizen migration, establishing a space and socioeconomic portrait in the neighborhood. From this context, our analysis seeks to understand the social and spatial impacts occurred in Downtown neighborhood, the way in which the production and reproduction of the urban space in São Sebastião neighborhood and the implications resulted from the actions of the administrative power in restructuring of the urban space of Nova Cruz. In order to do so, a bibliographical research was used to compose our theoretic-conceptual mark, discussing the matter with authors such as Roberto Lobato Corrêa, Ana Fani, Milton Santos, Manuel Castells e Heri Lefvbre, among others, discussing on the subject of urban analysis, the concepts of urban space and the process of reproduction of the urban space. A field research was utilized in our area of study by means of primary data gathering through interviews, questionnaire and photographic register. Secondary data gathering was also obtained by means of bibliographical and documental research related to our study object. By these means, it was sought to contribute to the understanding of the urban space through its production and reproduction based upon the discovery of social and spatial practices

Um olhar sobre o cotidiano e as re-definições espaciais no Bairro Potengi, Natal/RN

This work aims to conduct an analysis on the production of space and the dynamics between social agents that act and interact, albeit in different ways, in the production and re-production space in the Neighborhood Potengi in Natal, Rio Grande do Norte. The neighborhood is undergoing a process of dynamism undeniable and has a daily marked by heterogeneity, especially as a neighborhood in transition. So your analysis, from the perspective of the dialectical method, contributes to the understanding of the production space can be analyzed through the study of the forms and content, and may contribute to its real apprehension. After all, the city reflects forms, assumes functions, features and content that dynamic influences and is influenced by human relationships. Thus, this research seeks to analyze the production of space, based on the observation and study of the rich daily life of different social agents that operate within concrete quoted

Análise crítica da (des)(re)construção identitária em produções de narrativas de mulheres vítimas de violência de gênero

La violence a été utilisée comme un outil de maintenance du système patriarcal qui hante encore notre société. In séré et légitimé dans / par notre culture, le régime patriarcal considère la femme comme un être inférieur qui doit être subjugué et maîtrisé, y compris par la force. Cette recherche a pour d'étudier, dans les pratiques discursives et sociales, les process us de (dé) (re)construction de l’identité dans les productions de récits de femmes victimes de violence sexiste. Par conséquent, nous nous efforcerons de vérifier les études d'autres domaines tels que les études culturelles, la sociologie, le féminisme, en tre autres. De ce fait, nous croyons que ce mémoire se trouve dans les études de Linguistique Appliquée et dispose d'un point de vue interdisciplinaire (MOITA - LOPES, 2006), en plus des domaines énumérés, nous utiliserons l’analyse critique du discours, la sociologie pour le changement social et linguistique systémique fonctionnelle. Pour l'analyse autour de la posture interdisciplinaire en Linguistique Appliquée, on utilise la méthodologie qualitative/ interprétative (Magalhães, 2001). Afin d'examiner les r écits du «je» de femmes victimes de violence, nous nous sommes servie des récits exposés sur Internet, puisqu'ils sont du domaine public. Ainsi, nous avons étudié que les rapports trouvés sur l’outil « commentaire » présents dans les rapports du site G1, p lus spécifiquement, les rapports sur la violence de genre réalisés en 2014 dans deux villes du nord - est : Piauí et Rio Grande do Norte, et dans une déclaration faite dans le programme "Profession Reporter" en 2011. Pour asseoir notre recherche, comme une m éthode d'étude et de théorie sociale, nous utilisons l'Approche Sociologique Communicationnel du Discours, courant lié aux hypothèses de l’Analyse Critique du Discours (Pedrosa, 2012a). Les données montrent que les récits du «je» dans l'outil «commentaire» sont divisés en deux groupes principaux: les récits de renonciation et les récits de persistance. Nous réalisons également que les sujets se déplacent dans les sphères d'identité selon leurs contextes narratifs. La recherche nous a permis de déduire enco re qu'il y a une possibilité de changement social à partir de la narrativisation des tensions identitaires et la reconnaissance des inégalités dans les relations de pouvoir.
