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

Chemical admixtures, when properly selected and quantified, play an important role in obtaining adequate slurry systems for quality primary cementing operations. They assure the proper operation of a well and reduce costs attributed to corrective cementing jobs. Controlling the amount lost by filtering through the slurry to permeable areas is one of the most important requirements in an operation, commonly controlled by chemical admixtures, such as carboxymethylcellulose (CMC). However, problems related to temperature, salttolerance and the secundary retarding effect are commonly reported in the literature. According to the scenario described above, the use of an aqueous dispersion of non-ionic poliurethane was proposed to control the filter loss, given its low ionic interaction with the free ions present in the slurries in humid state. Therefore, this study aims at assessing the efficiency of poliurethane to reduce filter loss in different temperature and pressure conditions as well as the synergistic effect with other admixtures. The temperatures and pressures used in laboratory tests simulate the same conditions of oil wells with depths of 500 to 1200 m. The poliurethane showed resistance to thermal degradation and stability in the presence of salts. With the increase in the concentration of the polymer there was a considerable decrease in the volume lost by filtration, and this has been effective even with the increase in temperature

O presente estudo objetivou analisar as características epidemiológicas das condições de saúde bucal de 98 idosos de uma Instituição de Longa Permanência para Idosos (ILPI) e de 125 participantes de Grupos de Convivência, de bairros periféricos, socialmente semelhantes, de Fortaleza, Ceará, Brasil, para orientação do tratamento odontológico. Investigou-se a autopercepção em saúde bucal desses idosos a fim de realizar uma avaliação comparativa entre eles e com os levantamentos epidemiológicos de base nacional (SB Brasil) e de base estadual (SB Ceará). Devido a alguns idosos da ILPI recusarem o tratamento dentário e a identificação do elevado percentual de demenciados, optou-se por realizar uma avaliação cognitiva, o Mini Exame do Estado Mental (MEEM) visando identificar os aptos à reabilitação oral. Métodos: abordagem epidemiológica do tipo transversal, sendo a coleta de dados realizada por cinco examinadores, utilizando os critérios recomendados pela OMS (1997). Resultados: O CPO-D médio encontrado na ILPI, foi de 29,88, com predomínio do componente perdido (93,27%) enquanto o CPO-D médio dos não institucionalizados fixou-se em 30,17, com predomínio do componente perdido (63,70%). Também se avaliou o uso e a necessidade de prótese dentária: dos residentes na ILPI, 10,20% usavam prótese superior e 3,06%, inferior; 94,90% necessitavam de prótese superior e 97,96% de inferior; sendo a prótese total foi o tipo mais prevalente, 88,78% para ambos os arcos. O percentual do uso de prótese dos não institucionalizados foi 71,20% no arco superior, sendo 66,40% prótese total; já para o arco inferior, 32,80%, das quais 31,20% era prótese total. No presente estudo, tanto para uso quanto para necessidade, considerando ambos os arcos, a diferença entre os idosos institucionalizados e não institucionalizados foi estatisticamente significativa pelo teste Qui - quadrado (p<0,001). Como resultado do MEEM, observou-se deterioração cognitiva (escore ≤ 12) em 37,25% dos entrevistados, bem como um declínio cognitivo com o avanço da idade. Conclusões: Os resultados apontam que há um maior percentual de uso de prótese total no arco superior e maior frequência quanto à ausência de próteses de qualquer tipo no arco inferior. Evidenciou-se que os idosos pesquisados foram submetidos a tratamento mutilador e, como consequência necessitam de reabilitação oral, o que pressupõe a necessidade de políticas públicas para que isso ocorra efetivamente. Os participantes deste estudo caracterizam-se por uma autopercepção positiva da sua saúde bucal, a despeito das condições clínicas insatisfatórias e de precária saúde bucal, com acentuada prevalência de cárie dentária e edentulismo. O MEEM revelou deficiência cognitiva na maioria dos idosos, confirmando que a sua aplicação, previamente à reabilitação oral pode evitar desperdícios financeiros.Tais achados refletem a necessidade de implantação de políticas reabilitadoras em saúde bucal voltadas para o idoso; baseadas na perspectiva da integralidade como princípio doutrinário do Sistema Único de Saúde, o que redundaria numa melhor qualidade de vida, tanto pela melhor mastigação, digestão e nutrição, pelo maior aproveitamento dos alimentos, quanto pelo favorecimento à comunicação, pela dicção e fala, contribuindo para a socialização e consequente elevação da autoestima dessa clientela.

This doctoral thesis addresses the environmental issues and its vinculum with the tourism through the protected natural areas, in particular the conservation units, which consists in territorial areas created and demarcated by the government in order to protect ecosystems that have a high ecological and scenic-landscaped representativeness designed to the contemplation and controlled public visitation. In regard to its use for the touristic activities, are conceived while socio-environmental and symbolic materiality built around an imagery view of a nature-show, designed to attract visitors, aiming ensure the maintenance and reproduction of the capital in an entrepreneurial and preservationist way in the Metropolitan Region of Natal. It s a study about the Dunes State Park Jornalista José Maria Alves and the Jenipabu Environmental Protected Area, both created with the purpose of favor the implantation and empowerment of the touristic area through the State intervention as the main articulator agent of a new process of urbanization that uses the city marketing and the ideological discuss of environmental sustainability to recreate the imaginary of lost paradise and incorporate into the daily universe of tourists visiting the state of Rio Grande do Norte. The unveiling of this empirical reality made possible the construction and defense of the terms environmental entrepreneurship and compensatory preservationism, to explain how the formatting and idealization of this paradisiacal scenarios produce the commoditization of nature in an efficient and competitive way

This paper, Society, woman and education in Graciliano Ramos' novels, is a study object from the history of woman's education in the 1930 s, it is shown as a reading of woman's representation and the configuration of the Brazilian society in that period. São Bernardo, Angustia and Vidas Secas written by Graciliano Ramos (1892-1953) from Alagoas, are used here as sources associated with the reading of the Constitutions, of the Civil Code and of some presidential messages of that decade, also with the texts produced by other scholars that present some relationship within the thematic of this approach. The representation concepts and the configuration are essential for the production of this text. I run over to the configuration concept given by Chartier (1988, p.21) a definition to representation that can be understood as a relationship between a present image and an absent object that having the value of this because it is hamonized with it. I fall back upon the configuration concept given by Elias (1969) that understands it as been a social group performed by an interdependent network that occurs within individuals as a whole joined by any reason. The totality of each individual actions with each other, permeated by tension points and balance, is what characterizes each configuration; it can be a teachers and students meeting in a classroom or a friends' encounter in the bar table, for instance. The attempt of understanding woman's representation, being educated or not, the hole attributed to her in society according to her instruction degree and the way that same society saw this woman guided me through categories that were defined throughout the successive readings: gender, civil status, education, language domain, sexuality, marriage, family, ideal woman. I accomplish this reading that was possible to do - with the pretension of not having lost the relationship between history and literature nor forgotten each one peculiarities

This dissertation analyses, within a psychoanalytical e literary perspective, the enigma of blindness in Graciliano Ramos s work. The approach takes into account, mainly, the narratives of Histórias de Alexandre (Alexandre s tales) and Infância (Childhood memories) as both books speak of the same theme: the injured eye. The writer s work is scourged so that a broaden symbolism regarding the hurt eye can be found. The subject is discussed from three significant elements: fragmentation, helplessness and melancholy; all these form the creative aesthetic of Graciliano, merging into a single object. Fragmentation representing the internal shattered world of his characters, which is reflected in the environment; helplessness, directly related to feelings of rejection; and melancholy, characterized by a strong feeling of emptiness. The theme of isolation and loss is discussed based on Mourning and melancholy, by Freud, and other theorizers. There is also a brief dialogue with the Romantic and philosophical theories, which tries to explain the melancholic condition in the individual before moments of distress. Such theories are the support for the understanding of the helplessness of the hero in Graciliano Ramos´s literature and for the assumption that the blindness in the mistreated boy of the book Infância could be the language of the traumatic aspect that colors the entire text of the writer. As matter of fact, it constitutes in the lost object represented in the anguish of the author s characters

This thesis reflects upon the question of how does philosophy think a particular today, which is not only a legitimate philosophical task but a determinative characteristic of philosophy in general. Today's thought follows two paths: first, an hermeneutical-phenomenological analysis of Martin Heidegger's thought with regards to his own contemporaneity; and secondly, through the analysis of the contemporary phenomenon of Information Technology which in the present work is to be considered a privileged sign of our times and distinctive of the mindfulness of philosophy. Therefore, the starting point is an investigation of Heidegger's thinking on his own era to whom facticity is a way of accessing the fundamental question of philosophy. This thesis is led by three guiding words which hold onto a perspective of unity in Heidegger s lifetime of work: 1. Technicity, 2. History, 3. Language, to thereby develop a characterization of human existence as 1. Technopolitical, 2. Technoscientific, and 3. Technological. Finally, in keeping with this triangular characterization of the human, a philosophical comprehension of our times will be established and drawn by Information Technology illustrating three of its' factual signs that are understood to be the 'Remains of Being' today: The Emptying of Speech (Language); The Emptying of Science (History); The Emptying of The Object (Technicity). Through these nowadays phenomenon, it is possible to maintain a grip on the fundamental question, precisely when the task of philosophy seems to have peremptorily lost its meaning and come to its logical end and to show how philosophizing in the information era is as possible as it is necessary.

Morbidly obese patients present an increase in heart rate, blood pressure and perceived exertion besides lower walking ability compared to normal weight people. However, little is known about how these variables are presented after bariatric surgery. Moreover, despite the distance walked during the six-minute walk (6MWT) improve after surgery is not well established if the level of physical activity influences this improvement. Objective: To evaluate cardiovascular performance, perceived effort, ability of walking and physical activity level of patients with morbid obesity before and after bariatric surgery. Methods: The cardiovascular performance, perception of effort, the ability to walk and level of physical activity were assessed in 22 patients before (BMI = 50.4 kg/m2) and after (BMI = 34.8 kg/m2) bariatric surgery through the 6MWT. The heart rate, blood pressure and perceived exertion were assessed at rest, at the end of the 6MWT and in the second minute post-test (HR recovery). The ability to walk was measured by total distance walked at the end of the test while the level of physical activity was estimated by applying the Baecke questionnaire, analyzing domains occupation, leisure and locomotion and leisure and physical activity. Results: The HR at rest and recovery decreased significantly (91.2 ± 15.8 bpm vs. 71.9 ± 9.8 bpm, 99.5 ± 15.3 bpm vs 82.5 ± 11.1 bpm, respectively), as well as all the arterial pressure and perceived exertion after surgery. The distance achieved by the patients increased by 58.4 m (p = 0.001) postoperatively. Time postoperatively had correlation with the percentage of excess weight lost (r = 0.48, p = 0.02), BMI (r =- 0.68, p = 0.001) and the Baecke (r = 0.52, p = 0.01) which did not happen with the distance walked (r = 0.37, p = 0.09). Despite weight loss, patients showed no difference in the level of physical activity in any of the areas before and after surgery. Conclusion: The cardiovascular performance, the perception of effort and ability to walk seem to improve after bariatric surgery. However, despite improvement in the ability to walk by the distance achieved in the 6MWT after weight loss, this is not reflected in an increase in physical activity level of obese patients after surgery

Background: Obesity leads to alteration of lung volumes and capacities due to accumulation of fat in the chest wall and abdomen. Few studies have shown that weight loss induced by surgery improves lung function. Our objective was to evaluate the anthropometric development, pulmonary function, respiratory muscle, strength and endurance after weight loss induced by bariatric surgery. Methods: We evaluated in pre and post operative period variables of weight, BMI, NC, WHR and spirometric and respiratory pressure. Results: 39 subjects were evaluated, with age mean 35.9 ± 10.9 years, predominantly by women (76.3%). The weight mean decreased from 124.8 ± 17.5 kg to 88.8 ± 14.28 kg in post operative. The mean BMI ranged from 47,9 ± 5,6 Kg/m² to 34,3 ± 4,75 Kg/m². There was a significant increase in FVC from 3,63 ± 0,94 to 4,01±1,03, FEV1 from 3,03 ± 0,72 to 3,39 ± 0,85, FEF 25-75% from 3,41 ± 0,72 to 3,82 ± 0,94, PEF from 6,56 ± 1,47 to 7,81 ± 1,69, ERV from 0,35 ± 0,39 to 0,66 ± 0,38, MVV ranged from 103,43 ± 22,21 to 137,27 ± 29,84, all of them to p<0,01. The MIP and MEP showed no significant difference in pre and post operative. It was noted that for every centimeter reduced in neck circumference, an increase of 0.06 in FVC and 5.98 in MVV is observed. This is also observed in weight and BMI. Conclusion: We conclude that weight loss induced by bariatric surgery in obese provides a significant improvement in lung function and reduction of fat around the neck is more important in the generation of lung volume than the reduction of BMI

The necessity of the view of the Youth and Adults Education (EJA) subjects beyond of their academic failures becomes imperative for a reconfiguration of this teaching modality. Thus, the compromise of this study is to go into these subjects‘ universe, give them a voice and, therefore, understand, in general, the web of relationships between these subjects and the school. It is understood that it is not possible to figure out the means attributed by the subjects without consideration, as an essential element, the social context in which such means has been built. For the development of this study, the methodology adopted was the ethnographic research. The procedures used for the data construction were the participative observation, the semi-structured interviews with a focal group, and the individualized semi-structured interviews. For the understanding of the data constructed in the field, the content analysis technique was used, which reach the expectations of an interpretative analysis. The observation occurred mainly in the classrooms, on a public school, located in a City of Natal/RN. The interviews were taken with a sample of eight students, males and females, with 25 to 60 year-olds. Such interviews highlight that for the young adult students, the school is much more than a place to learn. They realize such space as enabler of social interaction, as well as the possibility of rising through new professional horizons and, therefore achieve a social mobility. For the older students, mainly among women, the return to the school benches brings into the learning discourse, the desire of making new friends, having moments of meeting, chatting and relaxation, finally, to forget the problems of the day by day. The school quotidian observation allows a better understanding of the action of the subjects in relationship with the school practices. Finally, it can be affirmed that seeking for the school has not only the intention to recover the time lost in the childhood. Learning remains as a secondary goal. It does not matter whether they will be retained or promoted to the next level at the end of the academic year, what really matters is to be in school.

Academic demands, new social context, new routines and decrease of the parental control, are factors that may influence the sleep pattern of freshman students at the University. Medical students from the Federal University of Rio Grande do Norte (UFRN) have a full-time course, subjects with high-level content, and, at the first semester, classes begin at 7 a.m. This group composed by young adults who still suffering with delayed sleep phase, common in adolescence, indicating that this class schedule can be inappropriate at this age. The reduction of nocturnal sleep during school days, and the attempt to recover sleep on free days – social jet lag (JLS), suggests that in the first semester, students suffer from high sleep pressure. High sleep pressure may reflect on cognitive tasks and performance. Therefore, the aim of this study was to investigate the relationship between sleep pressure and the academic profile of medical students from the first semester of UFRN, characterizing this population socio-demographically and investigating possible impacts on therestactivity rhytm and academic performance. A sample of 88 students, healthy men and women awswered the following questionnaires: Pittsburgh Sleep Quality (PSQI), Epworth Sleepiness Scale (ESS), Horne & Ostberg Chronotype (HO), Munich Chronotype (MCTQ) and “Health and Sleep” adapted. Actigraphy was used during 14 days to make actogramas and obtain non-parametric variables of the rest-activity rhythm and the grades of the morning schedule were used as academic performance. The JLS was used as a measure of sleep pressure. Statistics significance level was 95%. The population was sociodemographic homogeneous. Most students have healthy lifestyle, practice physical activity, use car to go to the university and take between 15 and 30 minutes for this route. Regarding CSV, most were classify as intermediate (38.6%) and evening (32%) chronotypes, needs to nap during the week, suffer daytime sleepiness and have poor sleep quality. 83% of the sample has at least 1h JLS, which led us to divide into two groups: Group <2h JLS (N = 44) and Group ≥ 2h JLS (N = 44). The groups have differences only in chronotype, showing that most evening individuals have more JLS, however, no differences were found in relation to sociodemographic aspect, rest-activity rhythm or academic performance. The homogeneity of the sample was limited to compare the groups, however, is alarming that students already present in the first half: JLG, poor sleep quality and excessive daytime sleepiness, which can be accentuated through the university years, with the emergence of night shifts and increased academic demand. Interventionsaddressingthe importance of good sleep habits and the change of the class start time are strategies aimed to improve student’s health.

The bioleaching of chalcopyrite has not been applied on a commercial scale due to the low process efficiency, so this process has been extensively studied in recent years. The bioleaching of chalcopyrite tailings becomes even more difficult by the presence of higher amounts of impurities, among them are the carbonates. The presence of carbonates in the ore promotes the increase in pH of the solution and may inhibit the development of bioleaching. Therefore, this research aims to apply the acid treatment for optimization of bioleaching process, in order to recover the lost copper throughout the process besides reducing the content of this toxic metal in the tailings pond. The removal and recovery of toxic metals is very important in protecting the environment and human health. The bioleaching experiments were performed in two stages, the first made up using the pre-treated tailing with sulfuric acid in bioleaching, and the second was made using the tailing without treatment with sulfuric acid addition at the beginning of bioleaching. The acid treatment was carried out in bioreactors with three different volumes of H2SO4 96% and a control experiment. All bioleaching experiments were performed in triplicate over a control, without addition of inoculum. The results showed that acid treatment was effective in removal of carbonates and managed to promote a good performance in the bioleaching of chalcopyrite in both steps studied, it is demonstrated that circa 47% copper recovery can be achieved.
