The literary critic Terry Eagleton obtained notoriety in academic circles when he was recognized intellectually for his bestselling book Literary Theory: An Introduction. In this book, the English author boldly proposes the end of literature and literary criticism. However, Eagleton proposed years before, in his book Criticism and Ideology (1976), a scientific system of analysis of literary texts, which seemed less radical, both in theory and in method, than in his later theoretical proposal. Based on this, the objective of this dissertation is to present the English literary critic´s initial method, explaining the reasons that led him to abandon his initial project - of develop a method of analysis of the literary text on a Marxist scientific perspective - and to propose, in the following years, in his most famous book and others, a revolutionary vision that would go beyond textual analysis and make literary texts have a practical intervention in society. Finally, we explain what would be his idea of revolutionary criticism

The thinking dialog between Heidegger s philosophy and the poetry of Hölderlin and Rilke must be dealt in language s domains. The difficulty to establish this dialog comes from the man in itself, unable to think out of the understructure of science and the modern technique. The poetic language was forgotten or ignored, turning itself obsolete in front of improvements and resources of the technique. Heidegger searches the essences to the poetry so may it be comprehended in its plenitude for the man. Technique, poetry and existence must be pronounced and investigated so the being shows itself again. To Heidegger, the man lives in a period of uncertainty due finding himself at the sunset of age. The uncertainty generates the poverty and the night of world represents the absence of god and original truth. Only with the fundamental comprehension of poetry, the man of today can project himself to the future not anymore as technique product, but with freedom to choose. The message of poetry of Hölderlin and Rilke, according to Heidegger s interpretation, transmits an alert to the contemporary man against the coming danger in his maintained relation with nature. The purpose of the following work is to build this thinking dialog, without disfigure the poetry, but taking approach over its essence, so from there to remove its true existential value.

We address the generalization of thermodynamic quantity q-deformed by q-algebra that describes a general algebra for bosons and fermions . The motivation for our study stems from an interest to strengthen our initial ideas, and a possible experimental application. On our journey, we met a generalization of the recently proposed formalism of the q-calculus, which is the application of a generalized sequence described by two parameters deformation positive real independent and q1 and q2, known for Fibonacci oscillators . We apply the wellknown problem of Landau diamagnetism immersed in a space D-dimensional, which still generates good discussions by its nature, and dependence with the number of dimensions D, enables us future extend its application to systems extra-dimensional, such as Modern Cosmology, Particle Physics and String Theory. We compare our results with some experimentally obtained performing major equity. We also use the formalism of the oscillators to Einstein and Debye solid, strengthening the interpretation of the q-deformation acting as a factor of disturbance or impurity in a given system, modifying the properties of the same. Our results show that the insertion of two parameters of disorder, allowed a wider range of adjustment , i.e., enabling change only the desired property, e.g., the thermal conductivity of a same element without the waste essence

The Tetraodontiformes order is composed for about 400 species of fish, distributed in ten families, with circuntropical distribution. The morphologic diversity of each family reflects in, part, the different levels of specialization. This group represents an ancestry after-Perciformes and constitutes the last branch of the diffusion of the Teleósteos, occupying a position of prominence. The phylogenetics relationships of the Tetraodontiformes exist diverse works examining and, in all, these families are recognized as groups brothers, being Diodontidae next to Tetraodontidae and Balistidae next to Monacanthidae. Although it possesss a representative number of species, the works involving of the families Balistidae and Monacanthidae are few exemplary, especially species of oceanic islands. In this work cytogenetic studies in five species had been analyzed Cantherhines macrocerus, Cantherhines pullus (Monacanthidae), Melichthys niger (Balistidae), Sphoeroides testudíneus (Tetraodontidae) and Chilomycterus antennatus (Diodontidae); through conventional coloration, Ag-NORs and C banding. Ahead of the different karyological trends of evolution presented by the Tetraodontiformes, the present work also searched to verify the relation existence enters the total size of the chromosomes with the amount of DNA in these groups of Tetraodontiformes. For such, they had been correlated the total size of the chromosomes of these species, with values of content of available DNA in literature. The cytogenetics analyses for the species C.macrocerusJ C.pullus (Monacanthidae) and M.niger (Balistidae), had disclosed 40 chromosomes, all acrocentrics. All possess only one pair of NORs and pericentromeric heterochromatin. For S.testudíneus the found dyploid number was equal 2n=46, with NF=78 (16m+18sm+8st+4a), while that for C.antennatus it possesss 2n=50, with NF=76 (4m+22st+24a). Both species possess simple NORs and pericentromeric heterochromatin blocks. In M.niger, the presence of positive marking (heterochromatin and NOR) in the secondary constriction in the second chromosomic pair suggesting the occurrence of a rearrangement, possibly a fusing involving these homologous ones, indicating that these events had been important for the establishment of the karyological history of this group. A maintenance of the chromosomic constancy found in the populations of C.macrocerus (Monacanthidae) and S.testudineus (Tetraodontidae) perhaps if must for the aiding of the gene flow through oceanic chains. These data contrast with the differentiated kinds of chromosomes of C.antennatus between the Northeast coast and Southeastern, suggesting that the ecological standards of each species, added to the conditions of the marine environment, can be responsible for the karyological delineation of each species. The found characteristics for the species C.macrocerus, C.pullus, M.niger, S.testudineus and C.antennatus add it the available data for other species of Tetraodontiformes. From the data gotten in the present study, it can be inferred that the DNA content possesss direct relation with the total length of the chromosomes

Les initiatives du gouvernement ayant pour finalité une réorganisation de la structure urbaine de la ville au début du XXème siècle reflètent le désir vécu par les membres de l'élite locale d'encadrer Natal dans les moules des grands centres urbains de la même période. Les élites désiraient transformer Natal dans une ville moderne. Dans ce but, le gouvernement s'est engagé dans la reformulation de quelques espaces physiques de la ville. Néanmoins, il fallait aussi d autres que les transformations urbaines, la ville devrait passer par des réformes sociales. De cette façon, ces groupes ont créées des nouvelles institutions et espaces de sociabilité qui affirmeraient la capitale de l'État comme une ville moderne. Les institutions formelles avaient un rôle imortant dans la construction de cette nouvelle ville convoitée par l'élite locale. Ainsi, à travers celles-ci, se diffusaient des nouvelles pratiques sociales qui seraient reflétées dans les espaces urbains. Dans des places tels, des cafés, des clubs et associations sportives, l'élite se distinguait du populaire. Dans ces places, leurs pratiques étaient légitimées, en contrepoint avec les pratiques populaires. C était dans les clubs et par les activités pratiquées par leurs membres que les idéals de l'élite circulaient, c était par là que l'élite se formait et se transformait. De cette façon, les aspirations d'un groupe social reflétaient dans l'organisation sociale des espaces de la ville

The present work regards, as its subject, the management of the urban space. It aims to survey the role assumed by the Conselho de Intendência Municipal de Natal (Municipal Stewardship Council of Natal) in the formation of a new urban order between the years of 1904 and 1929. For a better comprehension of the object of research, the milestone of the time span analyzed in this work was receded to the year of 1890, specifically at the first chapter of this dissertation. In this chapter, we will turn our attention towards an analysis of the referred council, on the regulation of its operation, the relations of this institution with the state government and its mechanisms of action in the city, among other topics. In the next chapter, we will delve into an elite who administrated the city of Natal during the first republic, understanding that the analysis of the formation of a modern city project by the Municipal Stewardship undergoes the comprehension of those who leaded this institution. In the third chapter, we will examine the limits of the municipal management to put into practice its projects to the upraise of a new Natal, between the years of 1904 and 1921. The last chapter, on its turn, presents a new Stewardship, reformulated after a process of administrative streamlining, and a city that transforms itself, especially during the O Grady tenure by receiving major constructions, which alter its main features. We will regard, as the main resources of this study, articles from the daily newspapers A República (The Republic) and Diário de Natal (Daily Natal), dictums, announcements, laws, state decrees and the messages disclosed by the state government. To build a way of analysis, we make use of authors such as Anthony Giddens, Peter Burke and Laurent Vidal, among many others who discuss concepts related to the proposed theme

As the space and the city are objects of desires, interests, seduction, sedition, appropriations, battles, victories, defeats, require to be analyzed historically. This research investigates and discusses the construction of public spaces in Jardim do Seridó City, backwoods of Rio Rio Grande do Norte, in the first decades of twentieth century, when the municipality was chaired by Heráclio Pires Fernandes, who ruled from 1917 to 1930 and was graduated from the University of Pharmacy of Recife, where he contacted the architectural, political and artistic influences circulating in the capital of Pernambuco. In the first decades of the twentieth century, the space of Jardim earns statements and practices, against the discourse of modernity, which sought to justify the title of Veneza Seridoense . At the time, the city had undergone several transformations in its public spaces through the construction of the Butchery, the Market, the Public Roads connecting the city to other urban centers, the building of the Bridge of the Pedra Lavrada Farm, the Elementary School Antônio de Azevedo , the creation of the Music Band Euterpe Jardinense , the Literary and Recreative Guild, the pavilion, the paving, tree planting, lighting, streets naming and listing of the annual painting of households, the arrival of automobiles, mail and telegraph. The construction of these new sceneries and the arrival of equipments generated impacts in the daily life of the population and were received differentiated ways by individuals involved in the process, which shows the tension between old and new, the relationship between history and space

The work is to make a brief discussion of methods to estimate the parameters of the Generalized Pareto distribution (GPD). Being addressed the following techniques: Moments (moments), Maximum Likelihood (MLE), Biased Probability Weighted Moments (PWMB), Unbiased Probability Weighted Moments (PWMU), Mean Power Density Divergence (MDPD), Median (MED), Pickands (PICKANDS), Maximum Penalized Likelihood (MPLE), Maximum Goodness-of-fit (MGF) and the Maximum Entropy (POME) technique, the focus of this manuscript. By way of illustration adjustments were made for the Generalized Pareto distribution, for a sequence of earthquakes intraplacas which occurred in the city of João Câmara in the northeastern region of Brazil, which was monitored continuously for two years (1987 and 1988). It was found that the MLE and POME were the most efficient methods, giving them basically mean squared errors. Based on the threshold of 1.5 degrees was estimated the seismic risk for the city, and estimated the level of return to earthquakes of intensity 1.5°, 2.0°, 2.5°, 3.0° and the most intense earthquake never registered in the city, which occurred in November 1986 with magnitude of about 5.2º

The Specialized Dental Care Centers (CEO) were developed to provide specialized dental care to the population, given the accumulated needs of health since the past. They must operate as units of reference for the Oral Health Team of the Primary Care, complementing the dental procedures performed at this level of attention. This study aims to assess the performance of CEOs of the Grande Natal Health Region as a strategy of Secondary Care consolidation in oral health through users, dentists and managers. For this to try to identify factors about access, hosting and satisfaction with the service, the actions developed in these centers, integration between the CEOs and the Basic Health Units (UBS), considering the reference and counter reference. Data were collected through semi-structured interview, conducted in four CEOs, among 253 users, 31 dentists and 4 managers. It was submitted to descriptive statistical analysis and to content analysis by software ALCESTE 4.5. The results revealed that the specialties of prosthesis, endodontics and surgery were the most sought by 38.2%, 23.7% and 21.7% of respondents, respectively. It was noticed that among users aged 18 to 30 years-old the greatest demand is for the specialty of endodontics (44.4%) and over 50 years for prosthesis (76.4%). There is a weakness in the reference and counter reference between UBS and CEO, because part of users goes directly to the centers without going before to the Primary Care and the majority does not want to return to the dentist of Health Unit. Satisfaction with care was reported by 90.9% of users, because they resolved the problems needed and were welcomed by the team. But the delay in care was the main factor for not satisfaction. For most dentists, some users could solve their problems completely in Primary Care, which shows the existence of unnecessary referrals to the CEOs, however they consider the existence of limiting factors in UBS that compromise the service. Most dentists revealed that some users do not get to CEOs with the basic dental treatment done, and some of them do not counter reference users. It can be concluded that the studied CEOs are being resolutive for those who access them, offering necessary care for the population, and if they don t account with this service, will encounter obstacles to resolution of problems, ranging seek care service in particular, in another public sector, or even giving up treatment. However, it is perceived the need of professionals training to understand the importance of the reference and counter reference, to that they can better serve and guide users. It is also important that cities offer better conditions to UBS and CEOs, so they can work together, with complementary actions of oral health, seeking full care, aiming for better resolution to the users' health problems

Considering education a support to health promotion, care integration and citizenship formation,the purpose of this research was to analyze the perception of the oral surgeons from the Family Health Program of Natal-RN over education in health as well as their performance as educators based on their activities on the program. A qualitative study was accomplished by a semi-structured interview and a Free Association of Words Test with 80 oral surgeons from the Family Health Program of Natal-RN. The instruments were analyzed through the meaning analysis and the Central Nucleus of Vergès Theory. The results showed a lack of planning in health actions so there is no standardization on the educative practices done by the oral surgeons which mostly are focused on scholars. There was an agreement among the group according to the oral surgeons´ perception about education in health that education is related to its function of recall prevention ideas to the population. Most part of the context units analyzed by the professionals´ speech show the knowledge of education in health as an inadequate behavior change instrument of the individuals. An interesting point was a quotation cited by some professionals that included actual themes such as citizenship, motivation and life quality, put inside the speech of education in health. To the oral surgeons the biggest difficulties on the development of the educative actions are due to the lack of incentive by the Municipal Health Bureau and to the detachment and lack of valorization of the themes by the population. The oral surgeons consider themselves co-responsible for the formation of a population which is able to request its health. They also mention the knowledge about the need of the community participation on the planning of the Family Health Program actions. Finally, it is notable the need for more encouragement so the oral surgeons can be more capable and have more interest in applying education in health on the perspective of a new model in health, because once capable and stimulated they can awake the population to education importance as a great transformation instrument for people searching for a fair, equalitarian and citizeness society

Th17 cells have been strongly associated to the pathogenesis of inflammatory and autoimmune diseases, although their influence on the carcinogenesis is still little known, there are reports of anti-tumor and protumoral actions. The objective of this study is to research the presence of Th17 lineage in lip and tongue SCC, using the analysis of the immunoexpression of IL-17 and RORγt, relating this immunoexpression with clinical and morphological findings in the attempt to better comprehend the role of these cells on the tumoral immunity of OSCCs. The results were submitted to non-parametric statistical tests with significance level of 5%. On the histomorphological analysis, it was observed the predominance of low level lesions on lip and high level lesions on tongue (p=0,024). It was not observed statistical significance between clinical stage and histological gradation of malignancy (p=0,644). For the immunohistochemical study, 5 random fields with greater immunoreactivity of the peritumoral inflammatory infiltrate were photomicrographed on the 400x magnification. It was done the count of lymphocytes which showed cytoplasmic and pericytoplasmic staining for the IL-17 cytokine as well as nuclear and cytoplasmic staining for RORγt. It was observed statistical significance difference on the quantity of immunopositive lymphocytes to IL-17 between the groups of SCC of lip and tongue (p=0,028). For the RORγt it was not observed statistical significance difference between the groups of SCC of lip and tongue (p=0,915). It was not observed statistical difference between the immunostaining of IL-17 and RORγt with histological gradation of malignancy and clinical staging. The findings of this research suggest a possible anti-tumor role of IL-17 for cases of lip. The results of the analysis of the RORγt are possibly due to the wide duality of the anti-tumor and protumoral role of the Th17 cells and their plasticity which, in the presence of different cytokines expressed on the tumor microenvironment, can alter its phenotype.

The main specie of marine shrimp raised at Brazil and in the world is Litopenaeus vannamei, which had arrived in Brazil in the `80s. However, the entry of infectious myonecrosis virus (IMNV), causing the infectious myonecrosis disease in marine shrimps, brought economic losses to the national shrimp farming, with up to 70% of mortality in the shrimp production. In this way, the objective was to evaluate the survival of shrimps Litopenaeus vannamei infected with IMNV using the non parametric estimator of Kaplan-Meier and a model of frailty for grouped data. It were conducted three tests of viral challenges lasting 20 days each, at different periods of the year, keeping the parameters of pH, temperature, oxygen and ammonia monitored daily. It was evaluated 60 full-sib families of L. vannamei infected by IMNV in each viral challenge. The confirmation of the infection by IMNV was performed using the technique of PCR in real time through Sybr Green dye. Using the Kaplan-Meier estimator it was possible to detect significant differences (p <0.0001) between the survival curves of families and tanks and also in the joint analysis between viral challenges. It were estimated in each challenge, genetic parameters such as genetic value of family, it`s respective rate risk (frailty), and heritability in the logarithmic scale through the frailty model for grouped data. The heritability estimates were respectively 0.59; 0.36; and 0.59 in the viral challenges 1; 2; and 3, and it was also possible to identify families that have lower and higher rates of risk for the disease. These results can be used for selecting families more resistant to the IMNV infection and to include characteristic of disease resistance in L. vannamei into the genetic improvement programs
