Constribuição técnica de um sistema de emulsão inversa a base de óleos vegetais para fluidos de perfuração

The developments in formulating drilling fluids to apply in petroleum fields are based on new technologies and environmental challenges, where the technical performance of a developed drilling fluid is used to produce a minimum environmental impact, showing great economy in costs. It is well known that the potential use of oil-based drilling fluids is limited because these fluids when discharged in the sea do not disperse as much as water-based ones and may form waterproof films in the seabed, having a profound effect on plants and animals living in this environment. The current works have been made in investigating fluids called pseudofluids, which are synthetic ester-based, n-paraffin-based and other fluids formed from inverse emulsion. In this research the principal parameters involved in inverse emulsion process were studied, in laboratory scale, using esters as main component. Others commercial drilling fluids were used as comparative samples, as well as samples from laboratory and field where these drilling fluids are being applied. Concentrations of emulsifier and organophilic clay, which are viscosity donor, were varied to verify the influence of these parameters, in different oil/water ratios (55/45, 60/40, 65/35, 70/30, and 75/25). The salt concentration (NaCl) is an indicative parameter of stability and activity of an esterbased fluid. In this research the salt concentration was varied in 10,000, 20,000, and 50,000 ppm of NaCl. Some rheological properties of the produced fluids were studied, such as: initial gel, plastic viscosity, yield point, and apparent viscosity. Through the obtained rheological measures, the existence of two systems could be verified: fluid and flocculated. It could be noticed that the systems were influenced, directly, by the oil/water ratio and emulsifier, organophilic clay and NaCl concentrations. This study showed the viability to use an ester obtained from a regional vegetable product babaçu coconut oil to obtain an efficient and environmental safe drilling fluid

Análise de necessidades de inglês para fins específicos em um curso de graduação em turismo

This study presents the results of a survey conducted in the area of English for Specific Purposes (ESP) in order to identify (1) the learning needs of students in a course in Tourism, their desires and lacks, at a federal university, with respect to use of English; (2) the needs of the present situation of teachers and the coordinator of that course as to the language; (3) the needs of the target situation of professionals (graduates) and companies with respect to this language. This research is a case study (STAKE, 1998; YIN, 2009) and was used for data collection, instruments such as questionnaires, semi-structured interviews, and document on the Tourism Course. To this end, it was adopted the theoretical basis for the constructs of English for Specific Purposes (ESP) Inglês para Fins Específicos (IFE) in Brazil, also known as Inglês Instrumental, whose foundation is based on the work by Hutchinson and Waters (1987), Robinson (1991), Dudley-Evans and St. John (1998), Celani, Deyes, Holmes, Scott (2006), among others, since this work is devoted to a specific area, Tourism. Results show that students opined the ability to prioritize reading and speaking into the classroom. Professionals reported that the latter is an indispensable tool for entering the labor market, yet they feel unprepared and need to attend English language courses in private language schools. The testimony of company executives also point to this deficiency. Finally, the present situation of teachers reveals that, while advocating the use of English in the classroom, this is not because students prefer their mother tongue. There is also an evident lack of needs analysis. Eventually, the coordinator said that there is some uncertainty as to the methodology, content and language skills worked, and the lack of interaction among teachers of English. It was concluded, therefore, it is important to conduct a needs analysis so that one can redesign a course that meets the different contextual needs: students, teachers, coordination, represented by the institutional needs, and the labor market

A escola enquanto espaço privilegiado de construção de "meninos de verdade" :concepções e valores atribuidos a essa instituição por crianças pobres

The intention of this study was to identify the school conception (conceptions) in the discourse of poor children. There were inquired two groups of subjects: the first was composed of children that inserted precociously themselves into the work market and must to go to school because they take part in one of the governmental programs, called, minimum income programs. The second will be composed of children that live in the poorest district in Natal/RN city. And don´t have obligatoriness to go to school. Thus, thematics like precocious work, minimum income program, capitalism, neoliberalism was aproached in our discussion. We also intended to make a illustrate with Pinochio Adventures fable, because its conception school is similar like real official discourse school from everybody. In cited narrative, the character Gepeto didn t know what s a truth child but knows that exist a place in city where his maledoll Pinochio would be one the school. Thus, this institution was destine by the justice and politics from Gepetos s city how children right. Pinochio, in the book s end, to be transformed himself in a truth child because learned in school responsible and goodness behaviors. To uphold our inquiry we used the Content Analysis and socio-historical perspectives. The result showed that the children know that exist differents schools: yours and other, to rich class. Their school is admited like good, it is a study place, it isn´t disorders place; and also make propotional to social ascencion. The children s discourses is similar to capitalism s discourse

A relação juventude-trabalho no projovem integrado do município de Natal/RN

The National Program for Youth Inclusion (ProJovem) has been created in 2005 in order to break the reproductive cycle of social inequality, through the improvement of the basic education and the professional qualification. Therefore, our objective is to discuss how the categories youth-work are inserted and implemented on ProJovem Integrado , which could be translated as Integrated , in Natal/RN. In 2008, ProJovem is has started to be executed based in four modalities: (1) Teenagers Socio-Educational Service, (2) Urban, (3) Worker and (4) Countryside Land Knowledge, aiming to serve a population from 15 to 29 years old who were seldom helped by specifics policies so far. In order to implement this research, three semi-structured interviews have been made, as well as observations at the program units and analysis of the official documents. In Natal, the operating modalities are: ProJovem Urban, which three units, divided in two districts of the city; the ProJovem Teenagers , which has ten units on Natal s four administrative regions; and ProJovem Worker , which were still structuring its courses until the beginning of the data collection. The data has been qualitatively analyzed through the Marxian Theory, tied to the Constant Comparative Method. The referred approach, based on the Grounded Theory, enables the understanding of the phenomenon s meanings through the perspective of the participants. The neighborhoods in which ProJovem s units are inserted has been characterized as well the Program s target. The results have been presented in three blocks: a) the modality s structure, which includes the implementation, functioning and operationalization of the activities; b) management of the modality s management, concerned to the main difficulties, expectations and functions; and c) the relation youth-work at the modalities. About the objectives and qualification and insertion goals, there is incongruence at the offer of occupational arches. We have observed that offered occupations are historically subservient and precarious. Hence they do not promote significant changes on the students career paths by usually inserting them into informal jobs or underemployments. Besides that, the professional qualification is very incipient. For that reason, it does not go with the necessary requirements to enable the youngster to enter the work world. It is considered that other researches are necessary to for better understanding of the remaining aspects of the relation youth-work

O significado do trabalho entre os jovens na transição de estudante universitário a profissional

The present study analyses the variability of the meaning of the work among young people on the transition from university to professional life, divided according to: university levels, knowledge area and graduation course. A hundred seventeen young people answered the questionaries structured on the components of the meaning of work. Semi-structured interviews were also made with parts of the sample about the themes related to the meaning of work on this way the information of the questionaries became complete. The answers of the interviews were studied through the analysis of the thematic contents. The results of such analysis and the answers of the questionaries were registered on the data base SPSS for Windows. The results of the statistic analysis made indicated that: (1) the centrality of work and the articulations among stronger spheres do not present variability according to level, area or course; (2) the course makes more difference values factors and descriptives factors than area and level; (3) the hierarchy of values presents variability according to area and the descriptive hierarchy presents variability according to course; (4) the level makes more difference specific attributes of the meaning of the work than area and course; (5) the standards of the meaning of work do not present variability according to level, area and course, but present variability according to type of the work market evaluation and planning the future work. In summary, the meaning of work present variability according to level, area and course of the young people, when studied in facets, except for the work centrality

As relações de gênero no trabalho: uma análise da inserção das mulheres e homens na rede de fast food

The purpose of this study was investigate the sexual division of the work in a chain of fast food, in Natal, RN. These aspects were analyzed with the ways of organization of the work, being made a case study. The main objective of this survey was to analyze the influence of gender relations in the insertion of men and women in the job market and to analyze the question of feminine submission in the professional world. These questions were analyzed considering the current period of the worldwide capitalism, from the characteristics of productive process and the growth of the service sectors. The research was made with a group of workers on the production sectors; attendance, management and human resources at restfood store, where six clerks were interviewed. Through our research, it is possible to perceive the permanence of the sexual division at the job in the interior of the productive processes at Restfood, that puts the woman in a subordinate position in relation to the man. This result can be confirmed if we considerate that the women, on this chain of food, occupy in first place the function of waitress and on this, trere s no functional progression, while her workmates (the men) for occupying other functions can progress inside the company. It was also evidenced that in a context of globalization of the capital, deregulation and disrespect of labor laws, the capital acts without any respect to workers. That was what we observed at the interviewer speech; the scarcity of the conditions of work and the constant disrespect of the labor laws. This way, we could evidence that the scarcity of work conditions hit men and women, but it has a crueler face with the women, and this one reproduces itself, day by day in the process of social reproduction, through family life, insertion in the world of the work, information and received social education. So, the capital explores all of them, but the gender relations create to the capital, the possibility of a different degree of exploration, becoming this way, the women main victims herself

As Mulheres e as Muralhas do Patriarcado e do Capitalismo: Terceirização e Precarização do Trabalho no Sistema do Capital

Our dissertation deals with the material living conditions of women workers and the relations of the wage who undergo in the hospital scope, taking as the locus of empirical research the Hospital Dr. João Machado, located in Natal / RN. Its purpose is to analyze the main implications of precarious work contracts in the economic and social dimensions from life of workers, explaining the main conditionings. The majority presence of women in wage relations not only in the hospital service, as well as in the service sector in general has motivated us to appreciation of the form of participation of women in health services and, in particular, at the hospital space. From the critical dialectical method, through processes of successive approximations to the reality, we analyze the patriarchal system of social relations and their repercussions for the Social and Sexual Division of Labor in the context of contemporary capitalist society, explaining the determinants of inequality, founded in social relations of sex, to the predominance of women in the hospital service and unveiling these participation trends in the labor market. The analyzes are based on bibliographic research - theoretical and methodological basis of research - combined with reflections that emerged from the field. The systematized and analyzed information reveal the uniqueness of the current social and economic situation of workers women with ties outsourced, paradoxically expresses on the expansion of the insertion in universe of labor, in overexploitation, in the precariousness of work and living conditions and persistent inequality in and in the social relations and in relations between the sexes

Metrópole digital: o jovem aprendiz na educação tecnológica

This thesis was elaborated in the scenario of Digital Metropolis Institute (IMD) – a supplementary unit at the Federal University of Rio Grande do Norte in the training of personnel with technical and higher level courses whose technical level training is associated with a process of digital inclusion, with the purpose of attracting young people to this area, with emphasis on Software and Hardware Development. It aims to investigate the cognitive change of young apprentice on technological education and his/her entrance into the labor market, through the formation and the social inclusion proposed by the Instituto Metrópole Digital; understanding the juvenile subjectivity production through the Instituto Metrópole Digital’s education by performance in the labor market; recognizing the Brazilian professional qualification public policies for youth and identifying the role of Tutoring in the learning process during the course of formation of the young apprentice of the technological education proposed by the Instituto Metrópole Digital.The clipping of the object of investigation was the process of cognitive change and constitution of subjectivity of the young apprentice in information technology (IT) in the IMD. It was searched support in theory Freireana as proposal that problematizes the policies and the process of formation and professional qualification, in the perspective of a citizen and liberating consciousness. By qualitative and ethnographic nature, descriptive-explanatory, it counts with the participation of young people, high school students from public and private schools, aged between 15 and 18 years. There are strong aspects: a cognitive change on the young apprentice of technological education onto overdrive high school as the student of the Instituto Metrópole Digital; it happened the social integration for those who remain in the course, both in the neighborhood where they reside and at school where he attended high school, the young man is recognized and becomes reference to other young, favoring him a life projection which when the activities of mentoring is learning motivator, it exerts a positive influence to the young on the continuity of studies, it provides intellectual and institutional affiliation and continuity in the investments to the academic life for a better insertion in the labor market, which refers to the modification of the life project-invest in academic training, in exchange for a technical job in the labor market. There are weak aspects: the absence of professor in the course, in his most important role, which involves awareness of his/her condition in action, in explicit position that the professional practice constitutes as this constitution requires reciprocity of its students and the context in which it operates; fragile formation of mentoring, absence of dialogues in the classroom that favors the formation of subject learning, mainly in guiding action, mediator of the young; There is a lack of methodological proposal to develop real projects on the labor market with problem solving and collaborative learning. It considers that without converting information into knowledge cannot discern clearly enough that there is no direct causal relationship between Professional and technological Education and the level of employability of the young worker certificate. It suggests to the evasion: a greater knowledge of the reality of the student of the Institute Metropolis Digital; better knowledge of youth and their expectations of life project; the Tutoring will be Teacher-tutor; investing in employability conditions effective the young into the labor market.

Ícones urbanos na cidade de Natal: arquitetura e desenvolvimento urbano na cidade do sol e mar

Natal has come through major changes in the last 150 years, since the actions of city beautification, in the 19th century, until the present day, when such transformations start to have the objective of including the city in the competition for the attraction of the capital flows and consumption, domestically and in a foreign sense. It is thought that the first initiatives aimed at increasing tourism in Natal occurred in the 1960s, however, it became apparent that only from the 1980s was there a significant increase in tourist activities in Natal and the Metropolitan Region, especially on the east coast of the state of Rio Grande do Norte, leading to an expansion of the labour market, the significant increase of foreign investment, territorial changes of great impact and the production of buildings primarily intended for the hotel industry and second residence for European tourists. Since then, the incentives for tourist activity in the state have been maintained and even increased, based on tourism aimed at natural beauties, local cuisine and events, which transformed the tourist activity in one of the main sources of foreign exchange for the city of Natal. In the early 21st century, the construction of high-rise condominiums, monuments (including the designer ones), such as the Parque da Cidade, designed by Oscar Niemeyer, were already established. Also, shopping centers and, in order to host the World Cup, the new football stadium, the Arena das Dunas, among others, which were aimed at local and foreign consumers, especially European, stood out in the city. It is understood that these new buildings, monuments and also renovations and restorations that were deployed in the city of Natal aimed at constructing a new identity for the city, within the process of capitalist development and urban spectacle. It is considered that the monuments and the iconic buildings are attributes of the cities aimed at selling locations as goods, establishing a new urban environment, a new role as cities, which aimed at seeking greater autonomy from the nation-state. In this research, it was sought to analyze the architectural object, that is, buildings and monuments built or restored in Natal and its relevance to the city marketing promoted by the city itself. It was found that, indeed, such buildings and monuments are inserted in contemporary architectural production as a basis for increasing the competitive nature of Natal. In addition, they reveal a capitalist mode of production, supported by public resources, operating in the production of urban space with a view to repeating the hegemonic model of a competitive city

Novas formas de governança pública: um estudo do arranjo articulado para Implementação da política pública nacional de aprendizagem profissional

The configuration assumed by the institutional governance arrangement established in the cities of Fortaleza and Natal, and its influence on the implementation of the National Public Policy of Professional Learning that promotes the formation and integration into the labor market of teens and young people aged 14 to 24 years old and people with disabilities is the aim of this thesis. The interactive governance approach, proposed by Kooiman (2003.2008) was the mainstay of the epistemological construction of the investigative process, also supported by contributions from Draibe (2001) concerning the stages of implementation of public policies. In methodological terms, the approach used was qualitative, being performed descriptive bibliographical and documentary research, applying semi-structured interviews with 44 subjects. Data were based on Bardin (2011), having been pre-established two categories of analysis: governance and implementation. The results pointed, among other things, to greater diversity and dynamics of the arrangement in Fortaleza, highlighting the much larger number of accessions of Nonprofit Entities (ESFLs) to politics, more frequent interactions between stakeholders from different organizational levels of governance, better alignment between guiding governance images and spaces designed to encourage interactions among actors and also greater local government involvement. In both cities studied, on the other hand, the study indicated that the failure of institutional capacities adversely affect the interactions stimulation and the exercise of meta-governance. The thesis concluded that the shape and intensity of the interactions between the actors involved in the implementation of the National Public Policy of Professional Learning and the way images are shared results in greater understanding and dissemination of the policy and create a favorable environment for cooperation and dialogue needed to collective work and favors the modeling of a governance structure able to handle the demands and characteristics of organizations and their participants in order to accommodate the divergent interests, make room for the creation of innovations and convergence of actions to achieve the objectives of the policy. Thus, the results of the Professional Learning Policy in the cities of Natal and Fortaleza, in terms of levels of entering the labor market, can be understood from the differences found in the governance structure of the institutional arrangement used for its implementation.

A crise de legitimidade na democracia representativa e o desatendimento aos direitos fundamentais: um enfoque participativo-educacional

This study aims to bring reflection on the legitimacy crisis of the Brazilian representative democracy, which results in non-attendance of fundamental rights, regarding legal and social facts in light of the existing constitutional order and seeking solutions in more democratic procedures and in a more humane, critical, democratic and collaborative education. It has been an issue for some time the understanding that the authorities do not meet the basic needs of Brazilian citizens - the only way to make them autonomous and sufficiently able to conduct their lives in a competitive and globalized labor market. Such situation only worsened - as illustrated by the social movements in mid-2013 - when people took to the streets, showing a noticeable dissatisfaction with public services in general, and some other groups presenting specific complaints in those events. To find solutions or at least suggestions for the reflection of the problem found, a current approach to public authorities was necessary attempting to reveal how the constitutional order authorizes their operation and how - in fact - they act. In this endeavour, the legitimacy of power was discussed, involving the analysis of its origin, to whom it belongs and the legitimacy of deficit situations, concluding that it is only justified as it gets more democratic influence, with greater participation of people in its deliberations and decisions, with its plurality and complexity. Research carried out by official institutions was necessary to have evidence of the low level of social development of the country and the nonattendance of minimum basic rights, as well as exposure to various acts and omissions which show that all public authorities do not legitimately represent the people's interests. The competence of the Supreme Court to establish the broader scope of the remuneration policy in the public service received proper attention, presenting itself as an effective means to promote the reduction of the remuneration and structural inequality in public service and contributing to better care of fundamental rights. Also, considerations were made about the Decree 8243/2014, which established the National Policy for Social Participation (NPSP) and the National System of Social Participation (NSSP) and took other measures with the suggestion of its expansion into the legislative and judiciary powers as a way to legitimize the Brazilian democracy, considering its current stage. In conclusion, it is presented the idea expressed by the most influential and modern pedagogical trends for the creation of a participatory, solidary, non-hierarchical and critical culture since the childhood stage. This idea focuses on the resolution of questions addressed to the common good, which considers the complexity and the existing pluralism in society with a view to constant knowledge update. Knowledge update is in turn dynamic and requires such action, instilling - for the future generations - the idea that the creation of a more participatory and collaborative democracy is needed to reduce social inequality as a way to legitimize and promote social welfare, with the implementation of a policy devoted to meet the minimum fundamental rights to ensure dignity to the population.

Escolarização de surdos no ensino médio em Natal/RN: vendo e ouvindo vozes

La Escuela Secundaria es la etapa final de la Educación Básica y su objetivo es profundizar los conocimientos adquiridos anteriormente, con vistas tanto a la continuidad de los estudios por parte de los alumnos como también a su formación profesional. Considerando el carácter excluyente y elitista de la Escuela Secundaria brasileña, solo recientemente las matrículas de los estudiantes sordos comienzan a ampliarse, y los profesores se deparan con el desafío de lidiar con ese tipo de discente en aulas regulares. Tanto la política de educación especial, desde una perspectiva inclusiva, como la Ley nº 10.436/2002 – reglamentada por el Decreto nº 5.626/2005 – posibilitaron un gran salto para la educación de los sordos en el país. La primera, por la defensa de una escuela atenta a las peculiaridades y demandas de sus discentes; la segunda, por reconocer la Lengua de Señas Brasileña como medio de comunicación y expresión legítimo de la comunidad de sordos y por indicar medidas que garanticen el derecho al acceso y al éxito escolar de la población sorda dentro de la escuela. Amparado en esas discusiones, este estudio tuvo como objetivo analizar el proceso de escolaridad de alumnos sordos de una Escuela Secundaria pública y estatal del municipio de Natal, Rio Grande do Norte. Se realizó un estudio de caso de tipo cualitativo. Los sujetos fueron tres discentes sordos que estaban terminando la Escuela Secundaria, una profesora de Portugués y dos intérpretes de Lengua de Señas Brasileña. Como procedimiento de investigación, se utilizaron entrevistas (grabadas en audio y video), observaciones y análisis de documentos. La participación de los sujetos sordos demandó cuidados éticos adicionales, tales como la traducción del Término de Consentimiento Libre y Aclarado y del guion de la entrevista a la Lengua de Señas Brasileña. Los resultados apuntan que el acceso y la permanencia en la escuela secundaria fueron garantizados, no obstante había poca participación en las clases y el aprendizaje de los contenidos escolares estaba comprometido. Había traductores/intérpretes de Lengua de Señas Brasileña, los cuales, sin embargo, solo iniciaron sus actividades tres meses después del comienzo del periodo lectivo. La profesora y los intérpretes no mantuvieron interacciones que facilitasen el aprendizaje o la participación de los estudiantes, quienes se encontraban siempre juntos y en un lugar determinado del aula, sin mayores interacciones con sus pares normo-oyentes. Los discentes sordos estaban terminando la Escuela Secundaria con edades superiores a 17-18 años, los cuales revelaron no tener perspectivas de continuidad en sus estudios o de inserción en el mercado laboral. Se concluye que la escolaridad de los alumnos sordos en la escuela investigada apunta a la necesidad de una reorganización curricular que atienda a las especificidades lingüísticas y sociales de esos estudiantes.

Viver e esperar viver: corpo e identidade na transição de gênero de homens trans

This work seeks to understand how trans men build their identities and live the transsexual experience in the relationships they establish daily onto “man” category. It could be observed that for it they engenders a specific gender transition in the midst of male transsexuality. Despite being under a complex amalgam of relations of exploitation and disciplinary domination, ways of being man are brokered for a living and entry into spaces where they are expelled for not conform the bodies that gender norms require. It is understood that gender transition is a process at the same time of organic and prosthetic body management and the assumption of your own identity. Thus, they build a politic of identity that creatively fixes a person's category as rights holder. The "transition" is therefore to transact from nonexistence to a place of humanity. This dissertation describes how this process takes place in the experiences of the speakers, observing the practices that bring out the male, front of class positions on the labor market, access to health, hormonization and own identity. Thereby, theories that fix them as expressing female masculinities or marginal to the hegemony do not find exactitude in their lives. The research methodologically started performing "multilocated ethnographies" that gave possibilities to in-depth interviews with 15 stakeholders from the Northeast, Midwest, Southeast and South of Brazil. Between 2014 and 2015, from the applying of network technique to the first dialogues in research, it was possible to build a participant observation by the trans men’s everyday life. Wherewith I was capable to behold their own private activities, as well as their public agency amid a trans activism collective in northeast, and the follow-up actions in which they were involved during the XII Encontro Nacional em Universidades de Diversidade Sexual e de Gênero (ENUDSG) held in Mossoró/RN. Therefore, the thesis engages to describe and understand the different ways of constructing trans male gender transitions in access to transsexuality and therefore a way of explaining their own trajectories in terms of people that exist as such, even though in the midst of narratives marked by emotions linked to "not live", to suffering and dehumanization.
