This paper presents a reconstruction of the historical trajectory of the Escola Industrial de Natal (Industrial School of Natal), in the period 1942 to 1968, based on the analysis of its cultural, social and pedagogical characteristics in a process in which its educational practices and the individuals who constructed them were getting involved in their actions. In this sense, the concepts of memory and school culture occupied a central place to understand the elements that characterized its administrative and pedagogical organization such as, for example, its curriculum, aims, disciplinary rules, clientele, teachers, leaders and the configuration of the institutional power. Designed to meet the demands of an industrial process that has strengthened in the country, throughout its history, the Escola Industrial de Natal was becoming a space predominantly occupied by individuals, from economically disadvantaged social groups in society, in search of a professional training that would guarantee them the exercise of a profession. The time frame from 1942 to 1968 allowed us to verify the changes caused by the Organic Law of Industrial Education of 1942, and the Law number 3.552, from 1959, in the organizational structure of this school. In this context, a characteristic that was evident was the purpose of making it flow between the students the love for the country, the respect for civic values and the belief that industrial education would be able to boost the country's development, an aspect that reached a bigger dimension from the 1950 s. Marked the disciplinary character of this institution the control over the actions of individuals, developed through its multiple educational practices in specific areas and in the predetermined time, under the constant gaze of those who participated, in some from, in driving this process. On the other hand, the vocational and human training, provided to students, allowed new opportunities for social integration, not only in the state of Rio Grande do Norte, but also in other regions of Brazil. Conversely, during his career, the Escola Industrial de Natal has remained being seen as an organized institution, with good teachers, but intended for the children of others

This study is part of the line of research on Teacher Education, circumscribed to the Graduate Program in Education of Federal University Rio Grande do Norte. In it, we have a qualitative research, whose object returned to the influence of continued education in social representation of inclusive education of Elementary School teachers. The same was done in an Elementary School of Cruzeiro do Sul city (Brasil/Acre) and performed with the participation of 11 teachers. We assume that thinking a continuing education inclusive presupposes reflect on the redefinition and resignification of practices undertaken by the teacher. Therefore, the teacher education is conceived as a continuum in which the teacher will be graduating in forming, shaping their way of being in social situations. We argue that in the context of interactions, we are going to reconstruct social representations that guide actions and attitudes about the objects that have meaning for the group. It was with the aim of identify the influence of these social representations and at the same time submit a proposal for continuing training in structured formative needs teachers who made use of collaborative action research. Since we believe that this can either meet the assumptions of a research and vocational training to enable that researcher and other teachers, collectively, problematizing situations of practice and, at the same time able to intervene in the same it. As procedures for obtaining information and analysis of the data, we performed, respectively, semi-structured interviews (individual and collective); reflective studies sessions and the analysis of content. The path of research revealed two social representations integrated one of inclusive education and another for student with disabilities. We noticed that although the teachers criticize the character sealed and limited of continued education courses that have frequented, reveal social representations of inclusive education and students with disabilities based on theories and concepts originated from such courses. As a result, represent inclusive education as an "education for all" and student with disabilities as someone "abnormal, different, but able to learn something . It is possible to state that from the moment the teachers approched theories about the principles of inclusive education and on the possibilities of student with disabilities took new discourses, and showed signs of change in the social representations before presented. In addition, we evidenced in this production that a proposal for training within the school, fomented by the needs teachers and having as methodology to collaborative action research, provides the (re)construction of collective knowledges and practices, sharing of experiences, hopes, discoveries and concerns and the development of cooperation and attitude for the (re)development of strategies to overcome the difficulties present in everyday teaching

This dissertation is the result of concerns with the theoretical-methodological and pedagogical learning processes occurred in the practice of physical education in school, which accompany me since the initial training, when I experienced learning in a piecemeal fashion, focused on technicality and sportivization. In order to better qualify the pedagogical interventions of physical education in school, I have always been worried on applying what I received at the University, but the routine of classes was always demanding others doings. In this sense, there were many moments of epistemological ruptures occurred in my training, in which I always sought new investment in training to account for the provision of a more humanistic and grounded in real educational precepts physical education. To that end I had to reflect on the pedagogical interventions throughout my training, in order not to carry out the activities as heavy doings, but as metamorphoses of knowledge and thus generating learning for students. Thus, this dissertation fits into this context with the overall goal of discussing my professional career, considering the epistemological ruptures of Physical Education, occurred in my training and expertise. The objective is also to identify the contributions of these formations in professional activities, centered on storytelling and reflection of significant experiences in the teaching of sports and Physical Education. We highlight the paradigm shifts, leaving the gymnastic methods, through dance-physical education method, psychomotor, reaching the contemporary critical theories experienced from the culture of movement as well as its implications for professional practice. We chose a qualitative research, using the autobiographical method, using as sources or techniques, narratives, photographic recording and video samples. In the studies within the area of education, for the most part, qualitative research came to oppose the positivist view of the quantification on analysis of social phenomena. New ideas were appearing in order to present innovative perspectives to understand the real. The survey data will be presented in narrated form (descriptive), analyzed based on the theoretical framework that guides the study, especially authors who discuss school physical education, vocational training and body conception. We believe our study may be of relevance for training in Physical Education that as from pedagogical reflections in certain historical realities, envisions being able to open new perspectives for the performance of other physical education teachers

The model of attention to health in Single Health System (Sistema Único de Saúde SUS) presupposes a human-resources policy which prepares professionals of health to guide the services and sanitary practices. The nurse, a member of health staff, takes over an important role in implementation of principles and standards of SUS, being its professional formation necessary to labor organization in this purpose. In this way this study objectifies to analyse the process of formation of the male nurse in the Politic-Pedagogical Project (Projeto Político-Pedagógico PPP) in the perception of learning and teaching of the Faculty of nursing FAEN of the University of The Rio Grande do Norte State UERN. It treats about a descriptive-exploratory study with qualitative and quantitative approach carried out with learning and teaching of the graduation nursing course. In the field research carried out between the months of november, 2006 and february, 2007, were used like instruments the documental research below PPP´s, structured interview directed to the learning and the closed questionnaire applied to the students of eighth and ninth semesters of graduation course. The results of data about the questionnaires elaborated according to National Curricular Patters (Diretrizes Curriculares Nacionais DCN) and the Instrument of Evaluation Course of Graduation MEC were organized according to six lists about the profile of the learning and teaching that participate of the research; of the didactical-pedagogical organization and PPP´s objectives to the just-graduates person to the didactical-pedagogical curriculum organization. For considering the interviews it was adopted thematic analysis of content discribed in lexical analysis by informatical program ALCESTE which provided the organization of the material in five categories: daily problems of SUS consolidation versus nurse formation, dichotomies about FAEN´s nursing course of curriculum versus principles of integralization of graduating process, the just-graduated one from FAEN and its professional insertion united to SUS politic-pedagogical project and the concern about the overcoming of dichotomies of graduation process abilities and necessary competences to the SUS performing nurse. The analysis of informations deriving from documental performance and field research resulted on the verification that, in spite of good intentions, the implementation strategies showed themselves fragile to cope with the rendering of expressed ideal on PPP. There is still a great gap between what´s thought as innovating graduating process and what´s being really implemented

One of the Ministry of Health s attempts at contributing to making collective health more appealing to health students is the Experience and In-Service Training within the Reality of the Unified Health Service Project (VER-SUS). Hence, the object of this investigation is to survey learners views on the teaching of nursing based in the experiences they have lived through in the VER-SUS. Its purpose is to analyze the views and lived-through experiences of nursing students on how the VER-SUS contributed to their professional education. This is a study of the descriptiveexploratory type with a qualitative approach. Eighteen undergraduate students from the nursing program at the Federal University of Rio Grande do Norte (UFRN), former VER-SUS participants, took part in this study, from 2006 to 2009. Information was collected using focus group techniques guided by a set of questions and semistructured interview with open and closed questions. The information collected was analyzed using content analysis technique, of the thematic analysis type. The UFRN Research Ethics Committee approved of the survey pursuant to Report Opinion number 223/2010 and CAAE number 0105.0.051.000-10. Lived-through experiences and in-service training gathered from the VER-SUS have contributed meaningfully to health education, as they helped understand the role of the university and of a health and nursing education within the hegemonic model of education. According to the views and lived-through experiences of nursing students who took part in the SUS project it was extremely relevant to use active methodologies in the teaching-learning process and have the facilitators act as liaisons for the SUS. It follows from this study that the VER-SUS does contribute to a health-nursing education and brings the students close to the reality of the community

Communication is seen as vital function. Through it, individuals and organizations relate to each other, the environment and the shares of their own group, influencing each other to turn facts into information. The user of the male part of a group of patients whose health policy is still in development. This fact can create insecurity in the nurse to establish a process that promotes disease prevention, promotion and / or recovery of health for that user. Aiming to elucidate this, the present study aimed to: apprehend the social representations of nurses communication with the users were male, looking for disease prevention, promotion and recovery of his health; identify the factors that influenced, positively or negatively on the effectiveness of nurses communication with the users were male and investigate the strategies used by nurses to clarify communication with the users were male. In order to achieve the goal raised, this study was a descriptive, exploratory and qualitative approach. Was based on theoretical and methodological framework social representations of Denise Jodelet and Serge Moscovici. The project has, through no Parecer nº 649/10, approval of the Ethics and Research HULW. During data collection, we used a semi-structured script and a diary interviews with 24 nurses in basic health units of district-Mangabeira Health District III, the city of João Pessoa (PB). The results were analyzed using the technique of content analysis according to Bardin (2007). Classifying the research subjects and identified three categories and five nuclei of the central ideas. The categories identified: the grasp of the RS communication of nurses with male users, identifying factors that influence the effectiveness of nurses' communication with users and male research on the strategies used by nurses to the elucidation of the communication with male users. The nuclei of the central ideas found: social representations of nurses' communication with the users of the male is externalized as difficult, different, difficult, not technical (knowledge) specific, with a dubious sense in relation to its therapeutic action, the factors examined as positive in this communication were based on the connection between professional and user look in detail and not mechanistic, in preventive actions, the dynamics of care, accessibility, participatory care, humanization, and qualification service. Whereas served as negative factors for the communication, signed on the behavioral differences of men, the feminization of nurses, lack of training for professionals in relation to the subject, prescriptive conduct and prejudice (concerns) sociocultural. Another related consolidated core strategies employed for the occurrence of such communication. Given these results, it was realized the importance of social representations for the consecration of a single language, the common understanding of reality on the nurse's communication with the user in male and determination of changes in the behavior of nurses and the user to the establishment of more effective strategies for obtaining a therapeutic communication between them

The implementation of the nursing process should be experienced by all nurses during their formative years. However, the lack of implementation of the nursing process for care planning during the educational process and the existing disorder in the formation process prompted the following research questions: What is the meaning of teaching the nursing process to the nursing professors? Do nursing professors use strategies and methods that promote critical thinking in their students? The objective of the study was to analyze the meaning that teaching of the nursing process has for the nursing faculty of the bachalaureate nursing course. Qualitative descriptive study conducted with a sample of 30 faculty members that taught nursing care courses in the nursing program of the Federal University of Rio Grande do Norte (UFRN) in Natal, RN. Two instruments were used, a questionaire and an interview guide. The questionnaire was designed to obtain sociodemographic, educational and work information, of faculty activities and of the teaching of nursing care. The guide was composed of five open questions regarding the understanding and perceptions of the nursing process, its utilization in teaching, and the nursing care teaching strategies. Interview data were submitted to content analysis techniques and interpreted according to the principles of Symbolic Interactionism. Six categories related to the analytical themes were identified: the nursing process as the guide for the care actions; clinical rationality; use of the care activities; teaching relevance; teaching barreirs; teaching strategies with focus on the abilities and competencies of the clinical rationale. Faculty perceptions regarding the teaching of the nursing process; nursing care approach in the nurses‟ formation. The study indicates that the participants understand the relevance of the nursing process a work instrument and that the use of this method during the nurses‟ formation enhances the abilities and competencies for critical thinking that is essencial for care. The strategies for teaching of abilities and competencies were identified, however the nursing faculty should use codes, direction and the influence so that the students can Interact and therefore stimulate the use of the nursing process

Currently, vegetable oils have been studied for bio-lubricants base that fits the new environmental standards. Since, in a world full of finite natural resources, mineral oils bring consequences to the environment due to its low biodegradability and toxicity, also it is important to consider that synthetic oils have a high cost The aim of this work is to obtain a biolubricant additived with oxide nanoparticles (ZnO and CuO) for better resistance to friction and wear, which is not toxic to the environment and have better adherence under boundary lubrication. The methodology consisted in the synthesis of bio-lubricants (soybean and sunflower base) by epoxidation reaction. Then, some physical-chemical analysis in bio-lubricants are made to characterize theses lubricants, such as, density, acidity, iodine value, viscosity, viscosity index. Later, the lubricants were additive with nanoparticles. The tribological performance was evaluated by the equipment HFRR (High Frequency Reciprocating Rig) consisting of a wear test ball-plan type. The characterization of wear analysis was performed by SEM / EDS. The results show that bio-lubricants may be synthesized by reaction of epoxidation with good conversion. Tribological point of view, the epoxidized oils are more effective than lubricant additived with the oxide nanoparticles, they had lower coefficients of friction and better rate of film formation in the study. However, because they are environmentally friendly, bio-lubricants gain the relevant importance in tribological field

Petroleum can be associated or not with natural gas, but in both cases water is always present in its formation. The presence of water causes several problems, such as the difficulty of removing the petroleum from the reservoir rock and the formation of waterin-oil and oil-in-water emulsions. The produced water causes environmental problems, which should be solved to reduce the effect of petroleum industry in the environment. The main objective of this work is to remove simultaneously from the produced water the dispersed petroleum and dissolved metals. The process is made possible through the use of anionic surfactants that with its hydrophilic heads interacts with ionized metals and with its lipophilic tails interacts with the oil. The studied metals were: calcium, magnesium, barium, and cadmium. The surfactants used in this research were derived from: soy oil, sunflower oil, coconut oil, and a soap obtained from a mixture of 5wt.% coconut oil and 95wt.% animal fat. It was used a sample of produced water from Terminal de São Sebastião, São Paulo. As the concentration of the studied metals in produced water presented values close to 300 mg/L, it was decided to use this concentration as reference for the development of this research. Molecular absorption and atomic absorption spectroscopy were used to determine petroleum and metals concentrations in the water sample, respectively. A constant pressure filtration system was used to promote the separation of solid and liquid phases. To represent the behavior of the studied systems it was developed an equilibrium model and a mathematical one. The obtained results showed that all used surfactants presented similar behavior with relation to metals extraction, being selected the surfactant derived from soy oil for this purpose. The values of the partition coefficients between the solid and liquid phases " D " for the studied metals varied from 0.2 to 1.1, while the coefficients for equilibrium model " K " varied from 0.0002 and 0.0009. The removal percentile for oil with all metals associated was near 100%, showing the efficiency of the process

The generation of effluent from the finishing process in textile industry is a serious environmental problem and turned into an object of study in several scientific papers. Contamination with dyes and the presences of substances that are toxic to the environment characterize this difficult treatment effluent. Several processes have already been evaluated to remove and even degrade such pollutants are examples: coagulation-flocculation, biological treatment and advanced oxidative processes, but not yet sufficient to enable the recovery of dye or at least of the recovery agent. An alternative to this problem is the cloud point extraction that involves the application of nonionic surfactants at temperatures above the cloud point, making the water a weak solvent to the surfactant, providing the agglomeration of those molecules around the dyes molecules by affinity with the organic phase. After that, the formation of two phases occurred: the diluted one, poor in dye and surfactant, and the other one, coacervate, with higher concentrations of dye and surfactants than the other one. The later use of the coacervate as a dye and surfactant recycle shows the technical and economic viability of this process. In this paper, the cloud point extraction is used to remove the dye Reactive Blue from the water, using nonionic surfactant nonyl phenol with 9,5 etoxilations. The aim is to solubilize the dye molecules in surfactant, varying the concentration and temperature to study its effects. Evaluating the dye concentration in dilute phase after extraction, it is possible to analyze thermodynamic variables, build Langmuir isotherms, determine the behavior of the coacervate volume for a surfactant concentration and temperature, the distribution coefficient and the dye removal efficiency. The concentration of surfactant proved itself to be crucial to the success of the treatment. The results of removal efficiency reached values of 91,38%, 90,69%, 89,58%, 87,22% and 84,18% to temperatures of 65,0, 67,5, 70,0, 72,5 and 75,0°C, respectively, showing that the cloud point extraction is an efficient alternative for the treatment of wastewater containing Reactive Blue

Environmental Laws and Regulations to dump wastewater are increasingly relevant and, together with pressure from environmentalists, provide awareness of academics in search of solutions. In Brazil, federal law, through Resolution No. 357 of 17/03/05 of the National Environmental Council - CONAMA, in Article 24 deals with the disposal of these effluents. Water pollution with heavy metals is concern because of the difficulty of the treatment and removal from the environment. Copper, for example, is a metallic element and in the form of salt is very soluble in water which dificults its removal. In this context, this study aims to evaluate the extraction of copper with acrylamide polymers through the process of assisted flocculation followed by filtration. Therefore, we used acrylamide polymers, produced by SNF Floerger, with varying degrees of ionicity which is the parameter examined on the extraction of copper. We used the FA polymers FA 920 SH, AH 912 SH, AN 905 SH, AN 910 SH, AN 923 SH, AN 945 SH, AN 956 SH and AN 977 SH, which have anionicities different from each other and growing in that order. The parameters temperature, pH, concentration of the copper solution and stirring speed are fixed. The polymer solution was added to a solution of 200 ppm copper, varying the concentration of polymer. After stirring, an assisted flocculation occurred followed by filtration of the effluent. The filtrate was analyzed by atomic absorption spectrophotometer and the percentage removal of copper ranged from 63 % to 97 %, noting that polymers with higher ionic charge were responsible for the highest percentage of copper extraction. The results of this study showed that these polymers can be applied in the treatment of wastewaters containing metals such as copper

This study investigates a new treatment system of wastewater by anaerobic and aerobic biological filters for nitrogen modification. The main objective of this study was evaluate, on a pilot scale, quantitatively and qualitatively the bacterian nitrifying community in a experimental sewage treatment system made by aerobics biological filters in series, in search of figure out the dynamic of nitrogen modification process. It was collected and laboratorial analysed microbiologically, regarding NMP of Nitrosomonas e Nitrobacter, and physical-chemically considering nitrogen sequence. We conclude that: the association in aerobic biological filters under nutrition controlled conditions and oxygen level allows the appearance of bacterian community responsible for the nitrogen modification; the method used, despite its limitations, provided the selection of autotrophic nitrifying microorganisms, allowing the identification of Nitrosomonas and Nitrobacter; the flow direction tested in the experimental unit did not affect the nitrifying bacterial community, certainly because they were kept drowned and did not occur flow speed that could breake the formed biomass; the nitrification process happened in aerated biological filters in all phases of the research, comproved by microbiological tests; in the third phase of the research the increase of the oxygen rate was significant for the nitrificant bacterian community in the aerate biological filters, allowing its growth, occurring relation between the efficiency of nitrification system and the quantity of organisms responsible for this process; the conduit used in aerated biological filters showed satisfactory performance support material to the nitrifying bacteria development

The growing accumulation of people in urban centers caused chronic problems of the cities to begin to take an increasingly unsustainable. Primarily related to lack of infrastructure coupled with sanitation and lack of investment in critical sectors such as health, education, housing and transportation, these problems start to deteriorate markedly the quality of life of city dwellers and put into test management policies of the spaces urbanized. To reverse this situation, shows is essential to the use of tools (highlighting this harvest rates and environmental indicators) that help in assessing the current conditions and may assist in predicting future scenarios. From the information listed above, now put the research seeks to present an index called ISBA Environmental (Sanitation Index) which looks at the four urban systems (water, sewer, solid waste and urban drainage) from the viewpoint of application in a geographical cutout specific - in this case the Drainage Basin XII, defined by the Plan of Urban Drainage Stormwater in the city of Natal, capital of Rio Grande do Norte. This index, together with analysis of other factors sought to trace the current conditions of the basin and thus, assist in proposing the best solutions. For the preparation of the index was applied a questionnaire with a sample of 384 (three hundred eighty-four) households that aimed to study two variables: access to services and satisfaction of the population in relation to these. The ISBA has shown that the system is the most deficient collection and disposal of effluents (ICE = 47.66%), followed by the drainage of rainwater (IDAP = 54.17%), water supply (AAI = 61, 36) and solid waste collection (IRS = 78.28). With the ISBA was possible to verify that the qualitative data shows whose subjectivity is evident (as is the case of user satisfaction) can be of great importance when an assessment, since we obtained the correlation coefficient between the variables "Access" and " Satisfaction "equal to 0.8234, showing a strong correlation between the existence / quality of service offered and the impressions of the population that receives them

A região semiárida sofre escassez hídrica. A fim de regularizar a disponibilidade hídrica nos períodos de estiagem, são construídas barragens. No entanto, a qualidade da água armazenada tem sofrido os efeitos do descarte irregular de resíduos no meio ambiente e das atividades antrópicas exercidas nas bacias hidrográficas. A degradação hídrica pode ser constatada a partir do monitoramento dos parâmetros de qualidade da água. Estes dados podem ser analisados através de métodos estatísticos tais como a Análise de Componentes Principais e a análise de agrupamento, que seleciona indivíduos com características semelhantes. O objetivo deste trabalho é realizar oagrupamento dos reservatórios do Rio Grande do Norte, com base nos parâmetros de qualidade da água, para a identificação de grupos homogêneos de reservatórios em termos de fontes de poluição. Serão objeto desse estudo as bacias Piranhas-Açu, Apodi-Mossoró, Trairí, Potengi e Ceará-Mirim. Os parâmetros mercúrio, chumbo, cromo, fósforo total, nitrogênio total e zinco contribuíram para a formação da primeira componente principal, que pode indicar poluição por metais pesados; sólidos totais, DBO, OD e cobre, para a segunda componente, que pode ser indicativo de poluição por matéria orgânica e atividades antrópicas; e clorofila a , cádmio e níquel, para a terceira componente, que pode indicar eutrofização e poluição por metais pesados. De posse das componentes principais se procedeu o agrupamento dos reservatórios, formando-se quatro grupos distintos. Os grupos 1 e 2 são constituídos por reservatórios da Bacia Piranhas-Açu, que apresentou maiores valores de metais pesados. O grupo 3, constituído por reservatórios das bacias Ceará-Mirim, Potengi e Trairí, apresentou maiores valores de DBO e sólidostotais e o grupo 4 é formado por reservatórios da Bacia Apodi-Mossoró. Nas Bacias do Trarí e Piranhas-Açu deve ser coibido o lançamento desordenado de efluentes e fontes de poluição difusas, e implantado um sistema de coleta de esgoto para minimizar a poluição por matéria orgânica

In recent decades, humanity has become increasingly concerned with environmental problems. Proofs of this are increasing initiatives in civil society organizations, private institutions and government actions, either local, state or national actions to promote environmental protection. The goal of this research is to contribute to the formation of citizens more aware of their responsibilities to sustainable development issues, simultaneously to their learning of physics in the secondary school. Thus, we have designed a research project that aims to evaluate the effectiveness of the adoption of the concept of sustainable development as a central theme in physics classes in high school. From this goal, we designed, implemented and evaluate lesson plans that aim not only to construct and apply the concept of energy, but also to understand their transformations and conservation law, as well as their processes of production, distribution and consume in the context of physical laws in which it is involved. Then, it was deliberately provided to students, during classes, to read, interpret and produce texts, by this way being able to think and start to have a critical view of the world around him, as well as absorb the energy concept and understand his occurrence in phenomena of nature and in technologies. The approach used for this was that constraining science, technology, society and environment - STSE. This teaching methodology has been applied in the IFRN Ipanguaçu campus, for students of two classes of first year of high school integrated course in agroecology and in technical computing. The survey results show the effectiveness of both methods with respect to the viewpoints of students in relation to the guidelines of sustainable development and the learning of physics content proposed. It is hoped with this dissertation to contribute to the formation of future men and women as citizens environmentally friendly, but also as a source of inspiration for teachers who wish to foster in its students such a critical position about civic education, from their classes
