O presente estudo traz uma reflexão sobre os discursos culturais afro-brasileiros e o lugar ocupado pela poesia em meio a uma sociedade racista. A pesquisa tem como propósito fazer um estudo da poesia de Oliveira Silveira (1968, 1970, 1977, 1981, 1987). Leva-se em consideração a relação da produção poética de Oliveira com as propostas do movimento da Negritude e o diálogo lúcido que o mesmo estabelece com poetas vinculados ao referido movimento e como Silveira sugere dentro da literatura a negritude como uma forma de intersecção na poesia brasileira. A proposta aqui apresentada observa também o hibridismo na poética de Oliveira Silveira ao se enfatizar um olhar sobre uma escrita comovida pelo traço do entre-lugar do discurso. Analisa-se a caracterização de uma literatura gerada pelo tom de denúncia ao desconstruir historicamente o que há muito tempo se estabelece como democracia racial . Em cumplicidade com a poesia regional do Rio Grande do Sul, a poesia de Oliveira vem permeada pela diversidade de ritmos que traduzem o legado da cultura negra mundo afora. Essa pesquisa sustenta-se nos estudos de Eduardo de Assis Duarte (2005, 2011) e Kabengelê Munanga (2008, 2009) sobre Negritude e Identidade na literatura afro-brasileira, que se caracteriza como um movimento de consciência pela reconstrução ou mesmo revisão histórica do que foi apagado no calabouço dos navios negreiros. As leituras de Eduardo de Assis Duarte fomentam novos questionamentos, põem em dúvida a existência de uma identidade essencialista. Aponta-se nessa travessia para uma pluralidade de identidades, construídas por inúmeros grupos culturais na encruzilhada dos diversos momentos históricos. Analisam-se, portanto, a partir da crítica que Stuart Hall (2011) faz ao considerar as ideias de diásporas, as fronteiras das margens no universo da pós-colonização. Por fim, há uma encruzilhada ao se pensar a partir de Kabengelê Munanga, o discurso da negritude e da identidade negra nas relações sociais e culturais afrodescendentes

Die Beziehung zwischen Literatur und Gesellschaft wurden, im Laufe der Jahrhunderte, aus unterschiedlichen Perspektiven analysiert. Die Wissenschaftler analysieren manchmal die Aspekten der sozialen Realität, sie betonen manchmal die Natur der literarischen Werk. Wir glauben, dass Antonio Candido einen Gleichgewichtszustand erreicht, als er das Konzept der strukturellen Reduktion oder Formalisierung entwickelt. Nämlich, der Prozess, bei dem die menschliche und soziale Leben zu einem Bestandteil der literarischen Struktur wird. Der Autor tritt eine Einbahnstraße und er kann Daten aus der sozialen Ordnung aufholen, ohne dabei die Materialität des Textes den Augen verlieren. Und das sind die theoretische Annahmen, die die Entwicklung dieser Arbeit leiten. Wir wollen zu zeigen, dass die Struktur der mamediana Lyrik aufdeckt, signifikante Daten der Gesellschaft, in der der Autore eingefügt wurde enthüllt. Folglich, wir analysieren soziale Thema, das sein Werk durchzieht. Zuerst, wir untersuchen, wie Zila Mamede den Alltag der Gesellschaft vertreten. Von der strukturellen Organisation der Gedichte, wir erkennen, das die Episode aus kleiner Städte ein Akt des Widerstands gegen die fragmentierte Profil der kapitalistischen Gesellschaf sind. Das ist, warum sie doch eng mit der Idee der Tradition erscheinen. Die dichotome Beziehung zwischen den regionalen Daten und der Element der Modernisierung etabliert, sie wird durch die Organisation des Raumes verstärkt. Während die Stadt bei konkrete gesellschaftliche Ordnung Spitzenbeträge verweist, hat die Landschaft eine harmonische und warme Form. Allgemeinen, die moderne Stadt von Zila Mamede geformt, ist eine Abbild der Industriegesellschaft. Die Bilder die Landschaft sind ein Gegenmittel gegen die Feindseligkeiten Merkmale der neuen urbanen Zustand. So, die Landschaft hat die Funktion von Umstrukturierung der Persönlichkeit des Einzelnen durch die Erfahrung der großen Städte betroffen verdinglichenden. Der Konflikt, der durch das lyrische mamediana läuft, sind Reflexionen des Prozesses der Modernisierung der Stadt Natal, ihres eigenen Landes die politische Instabilität, sie durch verschiedene staatliche Programme ging, während Der Autor seine literarische Tätigkeit verfolgt

Within the poetic scenario of Rio Grande do Norte the publication of Livro de Poemas de Jorge Fernandes, in 2007, marks, in the imagery of the Potiguar community of poetry readers, producers and critics, the beginning of the social circulation of an inventive ethos associated with the poet Jorge Fernandes de Oliveira (1887-1953). Regarding the event mentioned earlier as a point of reference, this research investigates the construction of such ethos based on the counterpoint between the poet s individual stylistic choices and the stylistic options that prevailed in the lyric production of the Twenties in the 20th Century. The corpus comprises poetic texts (by the poet under discussion and by other poets who were, then, regarded as icons of the poetry of Rio Grande do Norte) and texts representative of local literary criticism (produced both during the Twenties and in other decades of the last century). Support to this analysis is grounded in Mikhail Bakhtin s theory of the utterance (mainly regarding style) and in Dominique Maingueneau s theory of the utterance (mainly regarding ethos). During the course of this investigation, the research has outlined an inventory of the prevailing individual stylistic choices of Jorge Fernandes de Oliveira and the reasons why such choices point out towards the inventive ethos associated with the poet.

El objetivo de esta Tesis es la investigación literaria de la vida y la obra del poeta potiguar Walflan de Queiroz (1930-1995). Después de más de 17 años de su muerte, su poesía clama por una suerte crítica capaz de identificar sus características formales y estéticas. En ese sentido, se realiza el rescate de la producción poética de Walflan de Queiroz, con el fin de ofrecer los elementos que motivaron su discurso, su lirismo. Se pretende demostrar sus principales temas, como por ejemplo, el tenor metafísico, la angustia existencial, las pasiones platónicas, la muerte, la soledad, el silencio y la influencia de los poetas extranjeros, especialmente de la tradición romántica y simbolista, así como la manifestación de la religiosidad, de lo sagrado desde siempre encadenada a diversas tradiciones religiosas del mundo. Siendo así, la Tesis tiene como base teórica los fundamentos de la tradición poética y del imaginario religioso diluidos a lo largo de todo el estudio

This work has the purpose to analyze the female images unrolled at the Florbela Espanca (1894 -1930) poetry of her three books published, Livro de Mágoas (1919), Livro de Sóror Saudade (1923) e Charneca em Flor (1931, posthumous), showing how the female mythic constituents Eve and Lilith advance among the books, delineating the female image which culminates to the female poet image, free of moral conventions and social principles in the beginning of 20th century. For this exam, we will apply the Imaginary criticism, and realize a short explanation about mythic archetypes theories from C.G. Jung, Mircea Eliade, E. Meletínki and Gilbert Durand, theories that will lead us to make the connection between the mythic constituents and Nietzsche tragic constituents, from which we will explain how these female mythic images associated to reason and unreason mythic constituents, unrolled at the Florbela poetry, also reveal the tragic esthetic at her work

The development of digital technologies has opened up a new niche for artistic production. It began to emerge artworks that could only happen in the digital context. In this study, we investigated the syntax of defining digital poetry, recognized internationally as one of the possibilities of this new artistic practice, and how happens the meaning during the reading process. As research corpus, we chose the poem "Birds Still Warm From Flying", by american poet Jason Nelson. And we structure our analysis looking through three perspectives: the digital poem as a game; as the evolution of experimental trends of twentieth-century poetry; and as a representation of Rubik`s Cube, a famous three-dimensional puzzle from the 1970`s. Initially, we made some considerations about the construction of digital poetry as a hypermedia artwork, looking through convergence and hybridization of artistic and media languages. Then, we saw some similarities between Nelson`s poem and electronic games, based on our critical observations about the concept of interactivity. Subsequently, we wrote a historical overview about the poetic experimentation in the twentieth century, bringing examples of sound poetry and visual poetry as evidence that the birth of digital poetry is also the result of the evolution of these experiments. Finally, we use the Charles Sanders Peirce`s semiotics to analyze the signs that give references able to make us recognize the Rubik`s Cube in "Birds Still Warm From Flying"

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.

O corte de materiais por disco abrasivo é um dos processos que apresentam as melhores características de economia, eficiência e rapidez sendo muito utilizado no meio industrial. Fatores como porcentagens e homogeneidade da mistura dos componentes, tamanho, forma (abrasividade), tenacidade e dureza dos grãos abrasivos, tipos de ligantes e de abrasivos, velocidade de corte e velocidade de mergulho influenciam na segurança, no desempenho e comportamento da operação. Este trabalho apresenta um estudo sobre a influência da dureza dos discos abrasivos no desempenho do processo de corte em operações do tipo remoção a seco. O aumento da dureza dos discos propiciou um aumento da força tangencial de corte e da relação G, devido à mais forte ligação entre o grão e o ligante no compósito. Os resultados mostram que a dureza dos discos abrasivos afeta a economia, pois influencia na vida útil dos discos abrasivos em termos de números de cortes proporcionados; a produtividade, pois está relacionada com o número de trocas de discos desgastados; os esforços necessários para a operação, pois estão relacionados com as forças tangenciais de corte.

Com o grande crescimento tecnológico e a necessidade de melhoria, um dos materiais que ganhou uma grande gama na área da engenharia mecânica é a cerâmica, pois possui vantagens físico-químicas e propriedades mecânicas significativas sobre o aço. Entretanto, sua usinagem é um processo difícil e delicado, que requer ainda uma grande atenção em relação ao seu estudo. Assim, o processo de retificação é um dos métodos que tem apresentado bons resultados, porém um grande problema acerca de tal processo é o uso excessivo de fluidos de corte, o que se tornou uma preocupação mundial, já que os fluidos apresentam graves problemas socioambientais, além disso, o fluido de corte é responsável por uma grande parte do custo final do processo, provocando, desse modo, um grande interesse em pesquisas referentes a métodos alternativos de forma a reduzir o consumo e melhorar as características do fluido de corte utilizado. Este trabalho visa comparar duas técnicas de lubri-refrigeração, o método convencional e a Lubrificação Otimizada. O uso do método otimizado é uma alternativa à diminuição do volume de fluido utilizado, já que este tem como princípio a aplicação de uma menor quantidade de fluido de corte com uma alta velocidade, localmente aplicada, ou seja, com essa redução benefícios ambientais e socioeconômicas são obtidos. A análise do trabalho será feita a partir da avaliação das variáveis de saída do processo de retificação plana tais como o comportamento rugosidade e desgaste do rebolo, já que por elas é possível avaliar o processo em relação a qualidade da peça versus custo. Com essas analises, pretende-se avaliar se a técnica otimizada é viável a substituição da refrigeração convencional na retificação plana de cerâmicas.

Por meio de um trabalho multidisciplinar entre Engenheiros e Dentistas, foram estudados oito diferentes tipos de grãos abrasivos de diamantes para a fabricação de pontas adiamantadas e/ou rebolos de pequeno diâmetro. Verificou-se qual o grão mais adequado para ser empregado nas pontas, as quais são utilizadas em equipamentos que possuem um pequeno torque disponível. Uma metodologia de experimentação para avaliação da capacidade de corte destas ferramentas foi desenvolvida, utilizando-se o vidro como material a ser desgastado. Como resultados, observou-se que a estrutura e a friabilidade do grão de diamante afetam diretamente a capacidade de corte das pontas adiamantadas. Desta forma, o melhor tipo de diamante foi aquele que apresentou, ao mesmo tempo, as melhores condições de remoção de material e o menor preço.

He aim of this study was to evaluate the structural characters, herbage accumulation, nutritive value and performance of sheep in different tropical pastures. The treatments were two cultivars and two of the genera Panicum Brachiaria pastures under intermittent stocking and variable stocking rate, in the rainy season. We evaluated the masses and the components of herbage pre grazing in two layers, and after grazing. Chemical analyzes were made of the stems and leaf blades pre grazing in two layers. We used 48 male sheep and whole for the assessment of individual weight gain and area, and anestrous females to adjust the stocking rate. In the cv. Massai showed the highest herbage mass, leaf blades and dead material, and the largest volume density and leaf blade: stem pre grazing. There was no difference among cultivars for the percentage of leaf blade (PLB) in both strata, but the higher the PLB was higher than the bottom. The highest percentage of dead material (PDM) was observed in cvs. Massai and Marandu in the two strata. In cvs. Massai and Piatã were observed lower levels of crude protein in stem and leaf. In stratum 0-25 cm lower nutritional value was observed in the stem in the leaf blades did not grant the nutritional value among the strata. Herbage mass, leaf blade, PLB and proportion of stem in the residue of the Massai pastures were higher than cv. Aruana. There was no difference for efficiencies in harvest leaf and stem between the cultivars. The cv. Massai got the higher accumulation of leaf per cycle per day. Animals kept in grass swards Aruana had the highest average daily gain. The higher stocking rates and earnings per area were observed in grass swards and Marandu Massai. The cultivars are suitable for sheep meat production in the rainy season

Abstract: Several factors can affect the development of the broiler, among them we can highlight nutrition and management. In the context nutritional, mineral supplementation is a necessary practice because, in general, the diets did not contain these elements in sufficient quantity to meet the needs of poultry. Zinc is a trace mineral essential to life, participating in several important functions in the body. Generally zinc is added to diets of birds in inorganic forms (oxides, carbonates or sufatos), however in its organic form or chelated presents more bioavailable. The objective of this study was to evaluate the effect of levels of organic zinc (ZnO) in the diet of broilers from 1 to 42 days, housed in new or reused litter. The experiment was conducted in the poultry sector of the Special Unit for Agricultural Sciences EAJ / UFRN. 576 chicks were used 1 day of commercial strain Cobb, distributed in a completely randomized in a 4x2 factorial arrangement with four levels of ZnO 0, 40, 80 and 120 ppm and two environments, new bed (COn) and reused litter (CRE) resulting in eight treatments with six replications of 12 birds. In the pre-initial responses were linearly increasing levels of ZnO on feed intake and quadratic effect on body weight and weight gain. The levels of 72.41 and 70.05 ppm of ZnO in the diet of chicks improved body weight and weight gain, respectively. There was interaction between ZnO and the type of bedding used. The ZnO did not affect broiler performance in the growing phase. There was an interaction between levels of ZnO and type of bed used. The levels of 61.50 and 85.30 ppm organic zinc improves immunity and increases the deposition of zinc in tibia of broilers at 42 days, respectively. ZnO also increases the resistance of the skin of broilers at 42 days of age. Using Cre improves performance of broilers from 1 to 42 days old

The production of forage grasses is directly related to the morphogenesis. The knowledge of the morphogenetic and structural variables of forage plants is important for determining appropriate conditions of grazing livestock to ensure efficient and sustainable. Thus the objective of this study was to evaluate morphogenetic and structural responses of three genera of grasses, Brachiaria, Panicum and Cenchrus in a cutting regime. The experimental design was randomized blocks with three replications and six treatments. After each section were evaluated for forage production, appearance and elongation rates of leaves and stem, phyllochron, final leaf length, number of living leaves, leaf lifespan, leaf senescence rate, tiller density and tiller dynamics. On forage yield the highest values were obtained in cultivars Xaraes, Piata and Massai. The tiller density was higher for cv Massai. It is concluded that the cultivars of Panicum and Brachiaria had a higher tillering dynamics in increasing the turnover rate of tissues that are indicators of forage production, assuming that the cultivars of these genera are predisposed to use forage in the Northeast

This study was conducted to evaluate the consumption and digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), total carbohydrates (TC), non-fiber carbohydrates (NFC) and neutral detergent fiber (NDF) in sheep fed hay moringa (Moringa oleifera Lam) obtained with four cutting ages (28, 35, 42 and 49 days). We used 20 females Morada Nova breed, with 20kg of live weight, distributed in a completely randomized design and maintained in metabolism cages. There was a negative linear effect of age of cutting on DM intake, with an estimated maximum consumption of 0.67 kg / day for the hay produced at 28 days of cutting. It was also observed linear behavior, with an estimated maximum consumption 172g/dia, 0.36 kg / day; 18g/dia, at 35, 42 and 49 days old, for CP, OM and EE, respectively. For NDF, quadratic effect was found with advancing maturity of the plant. The apparent digestibility of DM, CP, OM and TC linearly decreased with advancing age of cutting hay Moringa oleifera. It was concluded that the hay Moringa oleifera showed better nutritional value after 28 days of cutting
