Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte

A semente de milho doce é leve e rugosa. A rugosidade torna difícil a classificação das sementes quanto à forma e ao tamanho e isso dificulta a semeadura. Uma solução para esse problema seria a utilização da técnica de revestimento. Assim, este trabalho teve por objetivo avaliar diferentes materiais de enchimento, cimentantes e corantes na peletização de sementes de milho superdoce e verificar quais combinações de materiais seriam eficientes na manutenção da qualidade fisiológica das sementes após o armazenamento e que permitissem vazão e distribuição uniformes durante a semeadura. Foram então testados doze materiais de enchimento (calcários 1 e 2, caulim, carvão vegetal ativado, areia, vermiculita, fubá de milho, farinha de trigo, polvilho de mandioca, amido de milho, celite e terra de diatomáceas), dois cimentantes (goma arábica e cascorez extra) e seis corantes (tintas guache, acrílica, plástica e para tecido, corante para alimento e gelatina). As avaliações da qualidade física e fisiológica das sementes revestidas e nuas foram efetuadas por meio dos testes: teor de água, fragmentação, peso de mil sementes, volume aparente e plantabilidade, germinação, primeira contagem da germinação e emergência de plântulas em campo. O revestimento de sementes de milho superdoce proporciona homogeneidade de forma e tamanho às sementes, melhora a vazão e a distribuição dos péletes na semeadura e não compromete a emergência de plântulas em campo depois de quatro meses de armazenamento.

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 study is connected to the research line Poéticas da Modernidade e Pós -Modernidade, of the Programa de Pós-Graduação em Estudos da Linguagem, in the subarea: Comparative Literature - CCHLA/UFRN. Its main goal is to see fragmentation of writing as an aesthetic resource highlighted in the work of Tutaméia by Guimarães Rosa (1908-1967), and in Livro sobre nada by Manoel de Barros (1916). We undertake as a starting point the view that these works are allegorical expressions. We have as a basis the German philosopher Walter Benjamin (1984) conception about baroque allegory, that uses amorphous fragment and constitutes a dialectical expression, in which each person, each thing, each relation, may mean any other one (1984, p. 196). We see the stylistic features as used by Guimarães Rosa and by Manoel de Barros in the construction of poetics capable of breaking the boundaries between artistic genres, literary and discursive, adding oral, musical and plastic elements to writing. We also analyze the development of fragmentary poetics, in which the voice of the narrator/lyrical I, the characters, space, plot and time exhibit the fragment as a factor that contributes to the great ambiguity of the two works and to create a new language, performative and vibrant, rich in alluring images, allegories

Helena is the romance of perishable and discontinuous title character denominator of a dialectic that does not consume and build the narrative by sequential fragmentation combined with episodic frame. The novel is a lightning stroke to the romantic literary project. Therefore, this study aims to find "objective" elements of the novel that would constitute a conception of literary nation proposed by Machado de Assis, as in classical writing, where women are engaged as a metaphor for the nation by a non-cultural heroism, as the example of the Greek myth of Helena, where the feminine represents a mythical image of the nation. The paper's theoretical conception of the history of Walter Benjamin, that is, that is constructed as an allegorical appeal, the conclusions about the disciplinary society of nineteenth century of Michel Foucault, the construction of the nation as a subtle game to remember and forget of Wander Miranda and the rhetoric of death and loss reflected in the speeches of the cultural heritage of José Reginaldo Santos Gonçalves, which allow you to analyze the work permeated by subjectivity and existential conflicts by Machado, who has it arranged in dialectic with the avant-garde literary romanticism and realism. In this relationship with the Greek myth of Helen, explained that characters with the nickname of Helena in Machado's work are not uncommon. As in classical Helena, Machado s Helena uses three rhetorical are the cause of the seizure of the nation. In this game of remembering and forgetting, in the daily plebiscite, Machado draw ideal images that forged our mythical past and commitment to the future. The suffering love of Helena is suffering from failure of the nation which would have led the author to the use of allegorical language, seeking a balance in the chaos generated by the opposition between cruelty and pity widespread view in an area where only left the character's confession guilt for the death. It is a simulacrum of unfinished nation, the space for the game of remembering and forgetting, while the rhetoric of negotiation of our Brazilianness

Cette recherche a pour but d approfondir des études qui mettent en lumière des particularités inhérentes au processus de l écriture fragmentaire. Notre intérêt pour ce thème provient de la poétique fragmentaire du Le livre de l intranquillité composé par Bernardo Soares, assistant de notaire et sémi-hétéronime de l écrivain Fernado Pessoa. Notre approche de ce genre textuel commencera par une méthodologie comparative qui nous donnera des notions pour que nous puissions établir quelques rapports de ressemblances et différences entre fragments, maximes, aphorismes et réflexions dont le corpus littéraire sera le journal intime de l intranquilité soarianne, ainsi que la fragmentation du simulacre d auteur au cours des années pendant lesquelles le Livre a été écrit. Le livre de l intranquillité lance des « pulvérisations » réflexives, lesquelles demeurent actuelles, étant donné que le processus de l écriture fragmentaire semble être toujours dans un mouvement constant et, donc, dans l ambiance du à venir. À partir de cela, nous avons passés pour quelques entraves pour essayer d établir une définition pour ce qui serait l écriture fragmentaire. Nous chercherons des points d intersection visant à établir des paradigmes pour obtenir des notions plus précises sur ce genre textuel, concernant les maximes, aphorismes et sentences refléxives.

It is possible to notice that the modern narrative increasingly seeks to invest its characters with a broad and complex nature, away from the well-defined beings of the traditional narrative. Through this work, we aim to make a study of Marcela, a character of the novel A ostra e o vento, by Moacir Costa Lopes, taking into account the way the complexity of the fictitious being is constituted through an analysis of structural, semantic, and thematic elements. We first will bring up a brief theoretical discussion about the character in a novel, and we also will carefully analyze the diagetic universe, presenting the complex path of the character further. Subsequently, we will focus on the structure of the narrative which creates a complex picture of the character, using the technique of crossed points of view as well as the technique of temporal fragmentation. Finally, we will investigate conflicting social relations that portray Marcela s disturbed inner side, as well as the metaphoric symbolic language, which furnishes a number of different representation of this character, impeding the creation of a well-structured coherent character. Studies of scholars such as Antonio Candido, Anatol Rosenfeld, Vitor Manuel de Aguiar e Silva, Fernando Segolin, Gerard Genette, Michel Zéraffa, among others, will guide our analysis

This treatise analyzes the identitary setting called Veneza Brasileira (Brazilian Venice) which is subscribed to the discoursive materialization related to the imagetic setting (literary and mediatic) produced about the city of Recife. The main investigation of this research is to examine the way how the identitary setting called Veneza Brasileira has been constructed in the imagetic setting practices about the city of Recife in the nineteenth and twentieth centuries. This study is subscribed to the Applied Linguistics and considers the theoretical perspectives that come from the Cultural Studies which investigation basis is focused on authors such as: Hall (2006); Bauman (1999; 2001;2005); Silva (2000); and Castells (2000) related to the discussion over identity, as well as the discussion over Urban Studies presented in Santos (1997; 1999); Ferrara (1998); and Pesavento (2001). Moreover it is also based on the theoretical basis found in Foucault (2004; 2006; 2007). Furthermore theoretical-methodological approaches rely on the French Discourse Analysis (DA) found in Orlandi (2001); Gregolin (2007); and Courtine (2006). On being so, this treatise aims to: analyze the meaning effects over the production of the identitary setting, especially the so-called Veneza Brasileira, in the imagetic setting discoursive practices (Poems, Post Cards and Touristic Guides) which are produced over the urban setting of the city of Recife. This research is characterized by being qualitative and interpretative and the theoretical analytical approaches contributed to the reading of both poetic and iconic images presented in the excerpts of poems from the nineteenth century and early twentieth century in: Manuel Bandeira s poems, Carlos Pena Filho s poems, and João Cabral de Melo Neto s poems which were produced in the early and late twentieth century. Moreover, this study observed some photographic images in Post Cards and Touristic Guides related to the visiting of historical sites in Recife. One could conclude that the imagetic setting discourse about Recife produced different identitary effects over the so-called Veneza Brasileira along these three centuries: in the nineteenth century, the poetry constructed the utopia city along with the meaning effect of identitary unit; as for the twentieth century, one observed an oscillation between a utopia/heteroutopia city meaning effect of both united and fragmented identity, the latter one is prevalent. As for the twenty-first century, the media reconstructed over again the utopia city, and consequently, produced meaning effect of identitary unit. These same meaning effects of identity either corroborate or contradict to/with the concepts of the postmodernism over identity along these three centuries. In other words, considering the imagetic setting, this oscillation occurs in the proportion of one finds an (ex) inclusion of social agents that construct these same identities.

The neighborhood of Nossa Senhora da Apresentação emerged in the 1970s, with its origins linked to housing policies carried out during the Brazilian Military Regime (1964-1985) by the Company Housing (COHAB) subordinated to the National Housing Bank (BNH). In this sense, the neighborhood is considered a periphery, located in the northern part of the city. With a large territory and population, it is considered the largest neighborhood in the state capital Natal - and its metropolitan area. The neighborhood also represents an urban space that presents social, economic and structural contrasts among them violence. The neighborhood is the leader in homicide rates in the capital. Therefore, the following study, based on empirical analysis of three distinct spaces within the neighborhood, aims to analyze how social actors perceive their own neighborhood and, specifically, segregation and violence. As this work shows, these two instances of urban life are not separated in the discourse of the residents. The main contribution of this work is the analysis of the impact of those views on the construction of social stigmas, reproduced within the neighborhood, on the fragmentation of the social and spatial fabric, and on the formation of poor and elitist spaces within the neighborhood, confirming the hypothesis that we are facing a New Urban Periphery

In this paper we investigate the spectra of band structures and transmittance in magnonic quasicrystals that exhibit the so-called deterministic disorders, specifically, magnetic multilayer systems, which are built obeying to the generalized Fibonacci (only golden mean (GM), silver mean (SM), bronze mean (BM), copper mean (CM) and nickel mean (NM) cases) and k-component Fibonacci substitutional sequences. The theoretical model is based on the Heisenberg Hamiltonian in the exchange regime, together with the powerful transfer matrix method, and taking into account the RPA approximation. The magnetic materials considered are simple cubic ferromagnets. Our main interest in this study is to investigate the effects of quasiperiodicity on the physical properties of the systems mentioned by analyzing the behavior of spin wave propagation through the dispersion and transmission spectra of these structures. Among of these results we detach: (i) the fragmentation of the bulk bands, which in the limit of high generations, become a Cantor set, and the presence of the mig-gap frequency in the spin waves transmission, for generalized Fibonacci sequence, and (ii) the strong dependence of the magnonic band gap with respect to the parameters k, which determines the amount of different magnetic materials are present in quasicrystal, and n, which is the generation number of the sequence k-component Fibonacci. In this last case, we have verified that the system presents a magnonic band gap, whose width and frequency region can be controlled by varying k and n. In the exchange regime, the spin waves propagate with frequency of the order of a few tens of terahertz (THz). Therefore, from a experimental and technological point of view, the magnonic quasicrystals can be used as carriers or processors of informations, and the magnon (the quantum spin wave) is responsible for this transport and processing

Poucos estudos avaliaram em longo prazo a variação no tamanho populacional das espécies de aves em fragmentos florestais. Para avaliar a riqueza e a abundância específica da comunidade de aves de um remanescente de mata semidecidual do interior do Estado de São Paulo, sudeste do Brasil, foi conduzido o censo da avifauna florestal utilizando-se a metodologia de contagem em transecção. Estes resultados foram comparados com levantamento realizado na mesma localidade 30 anos antes, e as aves foram classificadas de acordo com suas categorias alimentares com a finalidade de associá-las à tendência ao aumento/diminuição de suas abundâncias após este intervalo de tempo. Embora tenha havido predominância de espécies com diminuição populacional, todas as categorias tróficas analisadas apresentaram também espécies com aumento em suas abundâncias. A maioria das espécies com propensão a deslocarem-se entre fragmentos apresentou diminuição em suas abundâncias. Sugerimos que, em relação a suas abundâncias específicas, as categorias tróficas são igualmente afetadas pelos processos da fragmentação, e que a regeneração florestal sofrida pelo remanescente pode ter resultado na perda de espécies de bordas. Espécies cujas abundâncias tenham reduzido neste intervalo de tempo podem sofrer extinção local futuramente.
