Gregório de Matos: do barroco à antropofagia

The exponential figure of Gregório de Matos e Guerra has been subject of many theoretical discussions through the years, since his apparition in a public place, in the 19th century, and even more, during the 20th century, when he was salvaged by the modernist vanguard. As a result, there are yet two antagonist points of view linked to Gregório de Matos, on one side, there some researchers who defend him, on the other, some of them attack him. The first ones say this poet from Bahia was the first literary voice in Brazil, from the Baroque basis, while the last ones say he is a merely plagiarist of the Spanish poets from the 17th century, without a real contribution to the development of Brazilian Literature. With this in mind, this thesis follows the perspective this poet is an anthropophagus-baroque, devouring cultures, with an active participation in the process of our cultural and literary identity. For that reason, it was made a literature review about the biography of this poet trying to break romantic descriptions, emphasizing some scientific facts that can contribute to present the baroque profile of this poet. In this sense, it was discussed the History of Literature focused on this creole poet, mainly based on the historians point of view about the Gregorian poetry in the formation of Brazilian Literature scenery. In the defense of the hypothesis that Gregório de Matos was our first anthropophagus, this work aims to analyze how his poetry reveals the intrinsic characteristics of Baroque and Anthropophagy, focusing its carnivalesque aspect, showing to the world, with a satiric tone, the idiosyncrasies of human life. In this way, analyzing this corpus in Spanish is the strength of this thesis because, besides it is previously unpublished, it contributes to the comprehension of the anthropophagy as a theoretical mechanism that explains the process of formation of our cultural literary identity. Then, we have Augusto de Campos (1968; 1978; 1984; 1986; 1988), Haroldo de Campos (1976; 2010a; 2010b; 2011), Severo Sarduy ([1988?]), Oswald de Andrade (1945; 1978; 2006), Mikhail Bakhtin (2010), Octavio Paz (1979), Segismundo Spina (1980; 1995; 2008), Afrânio Coutinho (1986a; 1986b; 1994), Affonso Ávila (1994; 1997; 2004; 2008), among others, to constitute this theoretical scenery. The Gregorian poetry, in this way, have contributed to the formation of baroque-anthropophagic scenery in Brazilian boundaries, with a special attention to the transition of time, because he is not only from the 17th century, established by the historiography, but his work is present nowadays due to the contemporaneously of his themes, centered to the eternal doubts of baroque man

Assinaturas antropogênicas de elementos maiores e traços em poeira urbana na cidade do Natal-RN

Although there are many studies on urban dust contamination by heavy metals in developed countries, little attention has been paid to this type of study in developing countries, including Brazil. Therefore, a series of investigations were performed to provide signatures of heavy metals in urban dust and assess the potential sources in the city of Natal - RN-Brazil. The fraction of these sediments was studied to pass through a sieve of 63 micrometers. For the study analyzed two groups of samples, one collected in September 2009 at the end of the rainy season (9 samples) and one collected in January 2010 in the dry season (21 samples). So in all, thirty sediment samples were collected from the street. Then, in Fluorescence Spectrometry X-rays were determined major elements SiO2, Na2O, K2O, Al2O3, MgO, P2O5, Fe2O3, MnO, TiO2 and CaO, and trace Rb, Cr, Ni, Cu, Zn, Sr and Pb by an ICPOES was determined Zn, V, Na, K, Ni, Mn, Mg, P, Fe, Cr, Cu, Pb, Ba, Ca and Al from leaching HCl 0.5 mol L-1 . The results of the concentrations of elements show that the greater presence of these occurs in the dry season, except for Si which is higher in the rainy season. Analyses by geoaccumulation Index (IGEO) Enrichment Factor (EF), Contamination Factor (CF), analysis correlation and Hierarchical Cluster, confirm that Zn, Cu and Pb is anthropogenic character. Zinc may be derived from various sources related to motor vehicles or the road signs and street grids. The elements Na, K, Mg and Ca may be related to droplets suspended in air containing cations and anions present in seawater (salty), common in Christmas throughout the year, brought by winds SE-NW. The elements Na, Mg, Ca and K are the most abundant in seawater and were analyzed in this study. This indicates that the source of these additional elements detected by analyzing the contamination factor may be the very sea. Moreover, Ni, Fe, Cr and Ba can be either as a source of anthropogenic geogênica. The source of Ca is different, because it comes in lime and paint (painting guides of buildings and streets) in construction materials, but may also be present in sediments in the fragments of shells or carbonate bioclasts common in the coastal area

Em busca do estado participativo: os desafios da participação social na gestão ambiental

The existence of several negative indicators such as deforestation, pollution of rivers and urban growth disorderly suggest a scenario of serious environmental degradation in Brazil, allowing that the model of public management of the environment here is not practiced efficiently, despite to be a recognition-of environmental legislation as one of the best and most comprehensive in the world. One of the main causes of this problem is the low social participation in environmental management that often exists only in the formal plan. Thus, although defined as Democratic State, in practice, it is only a Figurative State. Based on the study of the origin of the state and social participation in the Brazilian State, in general scope, and some environment committees and public hearings in Rio Grande do Norte, as instruments of social control, in particular scope, it is possible to build a real Democratic State in environmental management, a Participative State, in which all players are aware of the responsibility and committed to the duty assigned to them by the constitutional text with the present and future generations

Predição em modelos de tempo de falha acelerado com efeito aleatório para avaliação de riscos de falha em poços petrolíferos

We considered prediction techniques based on models of accelerated failure time with random e ects for correlated survival data. Besides the bayesian approach through empirical Bayes estimator, we also discussed about the use of a classical predictor, the Empirical Best Linear Unbiased Predictor (EBLUP). In order to illustrate the use of these predictors, we considered applications on a real data set coming from the oil industry. More speci - cally, the data set involves the mean time between failure of petroleum-well equipments of the Bacia Potiguar. The goal of this study is to predict the risk/probability of failure in order to help a preventive maintenance program. The results show that both methods are suitable to predict future failures, providing good decisions in relation to employment and economy of resources for preventive maintenance.

Caracterização multi-escalar de bandas de deformação nas tectonossequências paleozóica, pré- e sin-rifte da Bacia do Araripe, Nordeste do Brasil

Deformation bands are structures, developed in porous sandstones, that has small offsets and they are not shown on seismic section. The deformation bands of the pre and synrift sandstones of Araripe Basin were studied in outcrop, macroscopic and microscopic scales. The hierarchical, cinematic and spatial-geometric characteristics, and also the deformational mechanisms acting during its structural evolution were established too. In general, the mesoscopic scale observation allowed to discriminate deformation bands as singles or clusters in three main sets: NNE-SSW dextral; NE-SW normal (sometimes with strike-slip offset); and E-W sinistral; further a bed-parallel deformation bands as a local set. The microscopic characterization allowed to recognize the shearing and cataclastic character of such structures. Through the multi-scale study done in this work we verified that deformation bands analyzed were preferentially developed when sandstones under advanced stage of lithification. We also infer that the geometrical-spatial complexity of these bands, together with the presence of cataclastic matrix, can difficult the migration of fluids in reservoir rocks, resulting on their compartmentalization. Therefore, the study of deformation bands can aid researches about the structural evolution of sedimentary basin, as well as collaborate to understand the hydrodynamic behavior of reservoirs compartmented by these deformational structures

Prevalência da síndrome metabólica e seus componentes nos estágios pubertários de escolares do sexo feminino norte-rio-grandenses

The diagnosis of nutritional status is extremely re levant in clinical practice and population assessment, due to the association betwe en body fat and metabolic alterations. The aim of this study is to analyze th e prevalence of metabolic syndrome (MS) and its components in the pubertal stages of f emale students in Rio Grande do Norte state, Brazil, in accordance with Internation al Diabetes Federation criteria. This is a cross-sectional study with 449 students aged betw een 8 and 19 years, stratified into pubertal stages systematized by Marshal and Tanner (1969), as follows: 27.6% prepubertal, 44.3% pubertal and 28.1% postpubertal, with mean ages of 9.4±1.27, 12.4±2.23 and 15.1±1.88 years, respectively. Preval ences were analyzed using distribution of frequencies and their respective 95 % confidence intervals, while the chi- square test and odds ratio were applied to analyze the associations between variables. The general prevalence of MS was 3.3% (CI: 2% - 5%) , without occurrences in the prepubertal stage, observing that it emerges from t he pubertal stage onwards with a prevalence of 2.5% (CI 95% 0.1% - 5%), 1% (CI 95% 0.4% - 2.3%) of cases with overweight and 1.5% (CI 95% -0.1% - 3.2%) with obes e individuals, while in the postpubertal stage the prevalence is 7.9% (CI 95% 3 .2% - 12.6%), 0.8% (CI 95% -0.8% - 2.3%) normal weight cases, 4% (CI 95% 0.6% - 7.4% ) overweight and 3.1% (CI 0.1% - 6.2%) obese individuals. There was an association (p<0.02) between pubertal stages and MS ( x 2 =5.2), with an OR of 3.3 (CI: 1.2 - 5), showing tha t postpubertal adolescents are more prone to SM than pubertals, while the OR i n obese individuals was 2.1 (CI: 2– 2.2) compared to the overweight. Body mass index (B MI) ( x 2 = 29.4; p<0.001) and age range ( x 2 = 13.1; p<0.001) showed a significant linear assoc iation with MS. Of the adolescents with MS, those aged ten years or younge r exhibited higher %G. The most prevalent components in all the stages were altered waist circumference (27.2% [CI 23% - 31%]) and low HDL cholesterol (39.6% [CI 35% – 44%]), which, coupled with hypertension, displayed significant differences in the postpubertal stage in relation to the other stages. The results show that MS emerges from the pubertal stage onwards in proportion to excess childhood body fat, a fact tha t calls for prevention strategies using an educational approach, reducing the large demand on the National Health System. Keywords: Metabolic syndrome, pubertal stages, risk factors.

Poéticas do rap engajado e juventudes nas periferias urbanas de Natal-RN

This thesis relates to issues present in the hip hop movement. Thus it includes youngsters grouped in different levels such as local, regional and national. The research deals with this broad segment. The analysis is made on those called “peripheral youth” It encompasses the juvenile segment, that is committed to a movement defined by these youngsters and activists, the so called “hip hop movement”. The research aims to analyze poetics present in rap, considered as an expression of resistance and inventiveness. The analysis was of micro politic nature and it dealt with the “peripheral scenario” present in hip hop Lelo Melodia in the Guarapes neighborhood in Natal-Rio Grande do Norte-Brazil. In this community, the group in known for their resistance attitude. The group´s opinion is not of opposition or force but it is seen in the sense of reinventing life that is currently attached to the persisting social inequality condition. In these terms, the research also deals with this committed poetic rap understood here as expressions towards resistance and inventiveness that is produced by these youth groups that belong to this hip hop movement. The focal group was the Lelo Melodia Group of the Posse de Hip Hop in the Guarapes neighborhood in Natal/Rio Grande do Norte in Brazil.

A geração de 27 e o barroco: la mirada exuberante

From the context of the degree‘s creation of Spanish literature and language‘s course, at UFRN, came the motivation to make this research, that presents a literary study of a poet‘s group known as Generación del 27, that came in to light at Spain, on 1920. A lot of aspects of this study are themes of many others disciplines, of this degree (Spanish Literature II, IberianAmerican Literature, Spanish Culture, Translation in Spanish Language). This work will also serve as inspiration to new reflections and proposes of translations, as bridges between the language that goes and the other that comes. It is the Translation as comprehension‘s negotiation between languages, it is the decir casi lo mismo, here in poem‘s form (ECO, 2007), in the attempt to conclude new learning, that will be shared with undergraduate and graduate students, being at teaching area, extension or new researches. To contextualize this generation‘s studies, were elected the anthologies organized by Gerardo Diego, called Poesía Española (Antologías), published on 2007, by Ediciones Cátedras, and the Antología Comentada de La Generación del 27, wrote by Víctor García de La Concha, published on 2006, by Editorial Espasa Calpe. The research took Generacion Del 27 as their object of research and - from many others critical reading about the poetry made by those young poets, their creative vocation of aesthetics and vanguard – wanted to understand the context of literary‘s creation of those poets del 27. We form our foundation with contributions by Antonio Maravall (2009), Eugenio D‘ors (s.d) Severo Sarduy (1999), Lezama Lima (2011), Alfonso Reyes (1958) e Deleuze (2005) among others that brought the comprehension of the baroque‘s language, giving emphasis to pluridirectional movement, deconstructing it‘s linearity, creating others new forms, as returns, circles, spirals favoring encounters, detachment or equal points of departure and arrivals. In this way, the poets del 27 approached the baroque of six hundred on a re-reading, and made of the third centenary‘s celebration of the Góngora‘s a Mirada exuberante death, to the return of baroque‘s spirit. Alfonso Reyes e Rubén Darío said that real lights highlighted the paths of this poets generation: The light that desdobra scintillates on García Lorca, Jorge Gullén, Dámaso Alonso, Gerardo Diego and the bullfighter Ignacio Sánchez Mejías, poets that expressed tributes in big style to Soledades author, at Madrid‘s Caffe and all Spain.

Escritura nômade e tédio em "Harmada", de João Gilberto Noll

In the context of poetic productions of modernity and postmodernity (Hutcheon, 1999), this paper, from the concept of nomadism (Deleuze, 2012), together with the philosopher Derrida's notion of writing (2009), has the objective to study Harmada the novel (1993), written by artist Joao Gilberto Noll, the aspect of Nolliana nomadic scripture and boredom towards deconstruction of the Romanesque style. The narrative focus on introducing a transit fiction, promoted by nomadisms scripture of the wandering narrator who, in the work constitution, will the conduct of language, a plot that invades the body of the characters full of boredom and foreigners themselves, moving in fragmented and fluid spatiality of narrating. In this perspective, the research is limited with theoretical and methodological foundation in poststructuralist discussions in relation to considerations of literary aesthetics and concerning the thinkers-teóricos- critics: Derrida (2009), Deleuze (1995), Foucault (1996, 2001), Barthes (1977), Svendsen (2006). Against the background of critical understanding, the nomadic writing Harmada interlace in three stages: first, in the author's language; Second, the characters, the narrator-protagonist leading, unnamed, living overwhelming crises and painful existential ambiguity, placed through the artist's metaphor failed under the sign of "missing" while searching for other possible artistic ways of being in the world; and, finally, the nomadic reading instance as presentification effect (GUMBRECHT, 2010) for a reader experimentation. Finally, our work addresses the relationship between the nomadic scripture and the experience of boredom as a strategic power in the literature do Noll gear.

Mapeando fundamentos do Constructo Neuromarketing com profissionais de empresa de publicidade

This study aims to acknowledge the domain level and influence of the neuromarketing construct. This is done considering professionals at advertising agencies in Brazil. The presence of concepts related to this new approach is very little divulged, and there are little analysis performed on this area. Thus, the research is of qualitative and exploratory nature and used as primary fonts books, articles related to marketing, neuroscience, and psychology as well as secondary fonts. A profound interview was realized aiming the main advertising agencies in Brazil. The public was composed by managers responsible for planning. A content analysis was performed afterwards. The advances related to the brain science have permitted the development of technological innovation. These go primarily towards knowledge and unconscious experiences of consumers, which are responsible for the impulse of decision making and consumer behavior. These issues are related to Neuromarketing, that in turn, uses techniques such as FMRI, PET and FDOT. These scan the consumer s brain and produces imagines on the neuron s structures and functioning. This is seen while activities such as mental tasks for the visualization of brands, images or products, watching videos and commercials are performed. It is observed that the agencies are constantly in search of new technologies and are aware of the limitations of the current research instruments. On the other hand, they are not totally familiar with concepts related to neuromarketing. In relation to the neuroimage techniques it is pointed out by the research that there is full unawareness, but some agencies seem to visualize positive impacts with the use of these techniques for the evaluation of films and in ways that permit to know the consumer better. It is also seen that neuroimage is perceived as a technique amongst others, but its application is not real, there are some barriers in the market and in the agencies itself. These barriers as well as some questioning allied to the scarce knowledge of neuromarketing, make it not possible to be put into practice in the advertising market. It is also observed that even though there is greater use of neuromarketing; there would not be any meaningful changes in functioning and structuring of these agencies. The use of the neuro-image machines should be done in research institutes and centers of big companies. Results show that the level of domain of the neuromarketing construct in the Brazilian advertising agencies is only a theoretical one. Little is known of this subject and the neurological studies and absolutely nothing of neuroimage techniques

A forma do privilégio: renda, acessibilidade e densidade em Natal-RN

The aim of this work is to understand the morphological expression of ground occupation by the higher income population, by focusing on population distribution in accordance with income layers and demographical density, as well as topological accessibility (HILLIER and HANSON, 1984) resulting from the urban grid structure. It endeavors to identify a functional organizing principle regarding the intra-urban space of Natal capital city of the state of Rio Grande do Norte, the research focus. In order to achieve this, census data as well as syntactic data were utilized for mapping and spatial analysis of income patterns, topological accessibility and demographical density using Geographical Information System GIS. The organizing principle was named as the Form of Privilege, a pattern that concentrates or tends to concentrate wealth, topological accessibility and low demographical density. Attempting to assess its extent, beyond Natal, this principle was applied to other Brazilian northeastern capitals such as: Fortaleza, CE; Teresina, PI; Aracaju, SE; Recife, PE; and João Pessoa, PB. Findings point out that although the urban structures of these cities are not immune to the Form of Privilege, Natal is emblematic of this phenomenon, a fact that demonstrates the perverse character of its spatial process, which historically creates privileged areas within the city, by means of the appropriation of accessibility as well as of the many urban benesses that are related to it by higher income groups at the expense of the major part of the population, which though being the people mostly in need of the benefits originating from the urban form are excluded from them

Geografia da dominação: um estudo sobre a organização espacial da terra do sal (Macau-RN)

This work aims to understand the spatial organization in the Town of Macau, State of Rio Grande do Norte, Brazil. This approach focus on bringing back the history of the town, the main personages responsible for the construction of this place, denominated "social agents", as well as its social processes and the spatial forms derived from them. As the personages and their practices were identified, it was found out the existence of a driving force for structuring, interlocking, and maintaining the actions carried out by the social agents during the time. Such actions were materialized in the urban space: "the social segregation". The social segregation takes place as a specific geography of domination. The outcome of those owning the best areas" and ways of accessibility in the urban space, varies from the enrichment by property valorization, because of the concentration of public investments of infrastructure, to the comfort of easily reaching all the daily needs related to the displacements in the urban space. In the latter case, such facility has contributed to improve life quality. While one takes advantage of the location in the urban space, others are negatively affected by the same process. This research identified the salina worker as the weakest element of this social structure, occupying the urban periphery of the town of Macau. Such area is characterized by the lack of services and urban equipment in opposition to the center of the town, the locus of elite. This way, it is established the most known segregation pattern: center x periphery, in which the space acts as a mechanism of segregation

Effect of cooling rate on properties of plasma nitrided AISI 1010 steel

In this work, AISI 1010 steel samples were plasma nitrided into 20% N 2 100 Pa and 400 Pa for N 2 and H 2 , respectively), temperatures of 500 and 580 °C, during 2 h. Three different procedures for cooling were accomplished after nitriding. In the first procedure the cooling occurred naturally, that is, the sample was kept on substrate holder. In the second one the sample was pulled off and cooling in a cold surface. Finally, in the third cooling process the sample was pulled off the substrate holder down into special reservoir filled with oil held at ambient temperature. The properties of the AISI 1010 steel samples were characterized by optical and electron microscopy, X-ray diffraction, Mössbauer spectroscopy and microhardness tests. Thermal gradient inside the sample kept on substrate holder during cooling process was measured by three inserted thermocouples at different depths. When samples were cooled rapidly the transformation of ϵ-Fe 2 − 3 N to γ′-Fe 4 N was inhibited. Such effect is indicated by the high concentration of ϵ-Fe compound zone. To get solid state solution of nitrogen in the diffusion zone, instead of precipitates of nitride phases, the cooling rate should be higher than a critical value of about 0.95 °C/s. When this value is reached at any depth of the diffusion zone, two distinct diffusion zones will appear. Temperature gradients were measured inside the samples as a consequence of the plasma treatment. It's suggested the need for standardization of the term “treatment temperature” for plasma treatment because different nitrided layer properties could be reported for the same “treatment temperature”.

Estudo da substituição de agregados miúdos naturais por pó de pedra em concreto de cimento portland

The sharp consumption of natural resources by the construction industry has motivated numerous studies concerning the application of waste to replace partially or fully, some materials, such as aggregates, thereby reducing the environmental impact caused by the extraction of sand and crushing process. The application of stone dust from crushing process arising as an aggregate for the production of Portland cement concrete is a viable alternative in view of the high cost of natural sands, in addition to the environmental damage which causes its operation to the environment. The stone dust has reduced cost compared to natural sand because it is produced in the beds of their own quarries, which are usually located close to major urban centers. This study examined the feasibility of using stone dust from the crushing of rock gneisses in the state of Bahia, replacing natural quartz sand. In the development of scientific study was conducted to characterize physical and chemical raw materials applied and molded cylindrical specimens , using as reference values Fck 20, Fck 25 and Fck 30 MPa ( resistance characteristic of the concrete after 28 days) in following compositions stone powder: 10%, 30%, 50 %, 100% and 100% with additive. The specimens were cured and subjected to the tests of compressive strength and water absorption, then the samples were subjected to the tests of X-ray diffraction and scanning electron microscopy. The results obtained showed that the composition with 10% stone powder showed the best results regarding the physical and mechanical tests performed, confirming the reduction in compressive strength and increased water uptake increased as the content of the powder stone in the concrete composition
