This research intends to narrate the journey of a simple man who was turned into a saint by a group of believers in Mossoró, west of Rio Grande do Norte. We recognized in the story of José Leite Santana, the "cangaceiro" Jararacá, an appropriated land to build an investigative approach of how characters as different as bandit and saint can be interconnected. From the believers speech, a narrative was created about these detachments of concepts based on the hero myth that is shown here as a part of men´s dealing with death

Este trabalho foi conduzido com o objetivo de avaliar o desempenho de matrizes pesadas, submetidas a diferentes programas de alimentação estabelecidos pela aplicação de modelos para predizer as exigências energéticas, após o pico de postura. O experimento foi conduzido no setor de avicultura da UNESP Campus Jaboticabal, com duração de 84 dias (três períodos de 28 dias). Foram utilizadas 740 matrizes de corte Hubbard Hy-Yield e 80 machos Petterson, com 55 semanas de idade. O delineamento foi inteiramente casualizado, com quatro tratamentos e cinco repetições de 37 aves por repetição (box) e um modelo fatorial 4´3 (quatro tratamentos ´ três períodos). Os programas de alimentação avaliados foram: T1 - Fornecimento de ração de acordo com o padrão da linhagem (428 kcal/ave/dia de 55 a 66 semanas de idade); T2 - Redução semanal de energia (2 kcal de EM/ave em cada semana); T3 - Fornecimento de ração de acordo com o modelo de exigência de EM, UNESP (2000); e T4 - Fornecimento de ração de acordo com o modelo, NRC (1994). O programa de alimentação com redução semanal de energia foi adequado para manter os desempenhos produtivo e reprodutivo das aves, indicando a possibilidade de redução de 2 kcal/ave/dia, em cada semana, na alimentação de matrizes pesadas após 55 semanas de idade. Os modelos UNESP e NRC proporcionaram estimativas mais elevadas das exigências energéticas que o modelo padrão, provavelmente em decorrência do ganho de peso das matrizes, que esteve acima do recomendado para a linhagem, promovendo maiores exigências de energia para mantença.

The objective of this work was to evaluate conditions the effectiveness of acetolactate synthase (ALS) and protoporphyrinogen oxidase (PROTOX) inhibitors in the Bidens pilosa control under two water deficit conditions, as well as to determine the influence of water deficit under the contents of soluble carbohydrates and protein of weed. The experimental design was randomized completely design with the treatments, with four replications, setup in a factorial scheme 4x2, with four herbicides (fomesafen lactofen, chlorimuron-ethyl and imazethapyr), and two water conditions (-0.5 MPa and -0.01MPa). At 7, 14, 21 and 28 days after application (DAA), was assessed visually control efficiency of herbicides. For the determination of organic solutes plants were collected at 24, 48, 72 and 96 hours after application (HAA). Herbicides controlled efficiently plants of B. pilosa, except lactofen, whereas the water deficit affected the efficiency of control of all the herbicides. The soluble carbohydrate content increased with the imposition of water deficit, however, herbicides and water deficit further reduction of soluble proteins in plants of B. pilosa.

The present work objective to study the configurations that the hinterland it acquires in the workmanship Great hinterland: trails, of Guimarães Rosa demonstrating as this author humanize this element, conferring to it characters universal mystics and through investigations, uncertainties, the auto-corrections of Riobaldo that become hinterland a metaphor of the human interior. Three are the chapters, that they will guide this work: the chapter 1 presents as element key for characterization of the epic one in Great hinterland: trails, the mining hinterland replete of trails, palco of exuberant vegetation, huge and multidimensional scene, where it has an entrecruzamento of fiction and reality. It retakes quarrel of critics as Manuel Cavalcanti Proença, Roberto Schwarz, on the existing epic character in the Great hinterland: trails, constructed from deriving myths of the universal culture, that they had been become popular. The brave and gracious knight, that it has its representabilidade in the popular culture. Thus the medieval hero, the knight represented for the Riobaldo personage, it is cognominado by Proença as Don Riobaldo of the Urucuia, knight of the general fields. O chapter 2 is a study on the popular culture in Rosa and Cascudo. Cascudo the example of Rosa also is exímio studious of the brazilian life, the regionalization and the popular manifestations proceeding from other cultures. O chapter 3 it has as focus of analysis two mitopoéticas personages: Diadorim e Luzia-Homem, which in the cited narratives they generally they assume functions generally atribute the men. Since children, if they dresses male. Valley to point out that Diadorim is not characterized as man, since in Great hinterland:trails if trajaq always as gunman. Luzia, when complete 18 anos pass if to dress as woman, but the stigma of male and female, inherited of the time where it coexisted the father folloies it for all the life. They suffer pain to have been born to fight and to não conhecer to love. They die you deliver the God. This study detects exactly that Diadorim and Luzia-Homem, are personages associates the myths of the universal culture and popular (sphinx, Jellyfish, Venus, Mother d water), that they possess similarities n the archetypes, that transit between the sexos masculine and feminine, without any sexual connotation, possesss it proper code of honr, of this not abdicating ahead of the death. Parallel, in this chapter two cascudianas workmanships willbe studies, that contemplate thematic of the dressed woman of man and being the woman without disguice: the enchantment tale Maria Gomes and romance Flower of tragics romances. The first one will be revisited in order to present subject in Great hinterland:trails through the Diadorim personage. As it will discourse on cases of brave women, cited for Cascudo, immortalized for the tradition, who had made history, that already is not disfarçam of men to carry through acts of bravery and honor.

Considering articles written for Fernando Pessoa in 1912 about The new Portuguese poetry , where he already proclaimed the appearance of the Super-Camões, poet that would be able to revolutionize Portuguese literature e, concomitantly, to make resurging from rubble the Portuguese nation; we understand that, decades before the writing of Message, the poet was already armed with a Will of Power , expression of Friedrich Nietzsche that incorporate the idea of resurgence to the man like creator of news values. Fernando Pessoa believed to make his poetical word, the epic, restoring word of the ideas of Messianism and Fifth Empire as the pushing force of the new Portuguese largeness. However, we look for to investigate the conditions of Malaise that surround the universe of the poem and that restrict its capacity of action on the reality in its return, a time that the space destined in modernity to the poet and to his poetry hindered him of a devoted and positive action, We select therefore theorist like Sigmund Freud e Walter Benjamin

This research comprises a study on the values and ideals attributed to Dix-sept Rosado, by the Coleção Mossoroense journal. Local researchers demonstrate how the Coleção Mossoroense constructs an image of Mossoró, forming in the members of the city an identity with the place, a social cohesion or creating one forms to see and to say about the Mossoró city. The Coleção Mossoroense, through Vingt-un Rosado together with its family, established a form of seeing and identifying of the Mossoró s population with the city, just because it associated and it was, at the same time, a movement at the same time social (civic parties for example), political (the domination of the Rosado s family) and cultural (the books and theatrical parties about the city). The conjunction of the Coleção Mossoroense as and with a social movement, cultural and political was capable to establish a social identity, a subjective constituent . With this background, it was possible to make a study of the image attributed to Dix-sept Rosado, by the Coleção Mossoroense, through an analysis of the inherent discourse in the works by Bakhtin (1989) and Bourdieu (2000), of and on Dix-sept Rosado in the Coleção Mossoroense based on. The image of Dix-sept Rosado was constructed by the Coleção Mossoroense after its death, and the responsible for this was Vingt-un Rosado, which was the chief-editor of the Coleção Mossoroense up to 2006, year of its death. The Coleção Mossoroense built an image of Dix-sept Rosado as an enterprising man, progressive and innovator, of great capacity of leadership and oratory (a conductor of the crowds ), popular and charismatic, an honest and dynamic politician. This image made by the Coleção Mossoroense, although when enhancing in surplus the qualities of Dix-sept Rosado have as objective to transmit an image of a heroic personage, it has some relation with the reality. Dix-sept Rosado was a man identified with its locality. This can resemble a regional nationalism. The attitudes of Dix-sept Rosado must be understood inside of a broader social context, of a time marked by the populist politics. Qualities also appreciated and developed inside of a specific historical context and determined both national and locally. The Coleção Mossoroense enhances the qualities of Dix-sept Rosado so that the current politicians of the Rosado s family can establish a link of continuity in its contemporary political practice

As plantas invasoras são constantes e diminuem a produtividade das culturas por competirem por espaço, nutrientes e água. Dessa forma, os agricultores adotam, em grande escala, produtos químicos eficientes no controle da lavoura e com alta toxicidade ao meio ambiente. Existem, no entanto, formas alternativas para o controle de invasoras, por meio de aleloquímicos presentes em algumas plantas, dentre elas, as medicinais. Este trabalho tem como objetivo analisar as propriedades alelopáticas dos extratos das plantas medicinais Cymbopogon citratus (DC) Stapf. e Sambucus australis Cham. and Schltdl. em inibir a germinação de Bidens pilosa L., sem interferir na germinação de Glycine max L. Merrill. Os extratos foram obtidos triturando-se 200 g de folhas com 1 L de água destilada. As sementes foram mantidas em B.O.D. à temperatura de 25ºC, com fotoperíodo de 12h de luz. Nas condições em que foram realizados os experimentos, constatou-se que o extrato de capim-limão inibiu a germinação de picão-preto sem que este inibisse a germinação da soja, enquanto o extrato de sabugueiro inibiu a germinação de picão-preto e a germinação da soja. Assim, indica-se a utilização do capim-limão, como um herbicida natural para o picão-preto.

A ocorrência de insetos fitófagos e de himenópteros parasitóides a eles associados, presentes em capítulos de Bidens pilosa são descritas para as condições do município de Botucatu, SP. Foram encontrados predadores de sementes da ordem Diptera, pertencentes aos gêneros Dioxyna, Melanagromysa e outro não identificado. As moscas Dioxyna depositam seus ovos no interior dos aquênios em estágios iniciais de desenvolvimento, permanecendo no interior do fruto até a emergência do adulto. Melanagromysa localiza-se entre as flores centrais desenvolvendose externamente aos aquênios. Foram observadas oscilações cíclicas e acopladas entre as curvas de abundância dos fitófagos e dos himenópteros parasitóides.

Com o objetivo de verificar possíveis correlações entre níveis de predação de capítulos de B. pilosa e o tamanho das plantas, bem como com o seu grau de agrupamento, o presente trabalho foi desenvolvido em áreas ruderais nos arredores da cidade de Botucatu, SP. em cada coleta, foram obtidos 15 indivíduos em fase reprodutiva, sendo dez deles provenientes de agrupamentos e cinco isolados, no período de março a setembro de 1993, totalizando seis coletas. Cada planta foi caracterizada quanto a parâmetros biométricos por meio de mensurações, contagens e determinação da biomassa das diferentes estruturas, avaliando-se também a ocorrência de predação nos capítulos. Nas duas condições de agrupamento, o tamanho das plantas foi altamente variável havendo, porém, maior freqüência nas menores classes de tamanho. de modo geral, não houve diferença significativa entre plantas agrupadas e isoladas no que se refere aos parâmetros biométricos analisados. Plantas maiores produziram maior número de capítulos e o nível de predação correlacionou-se positivamente com o tamanho das plantas, independentemente do grau de agrupamento das populações. A distribuição agrupada não condicionou, portanto, maiores níveis de predação, uma vez que plantas maiores dos dois grupos foram preferencialmente atacadas. Isto corrobora a Hipótese do Vigor proposta para explicar relações de preferência entre plantas e seus herbívoros.

Flexibilidade anterior do tronco (FAT) é um componente importante dos exames clínico e de aptidão física utilizado como indicador da função vertebral. O teste mais utilizado para sua quantificação é o sentar-e-alcançar (TSA), que considerara como padrão de normalidade o toque das mãos nos pés, com critérios e parâmetros de análise que independem das variáveis. Neste estudo, investigou-se a FAT em adolescentes, após o pico da velocidade de crescimento em estatura, em função do sexo, da velocidade de execução e dos dados antropométricos. Os índices foram obtidos em centímetros; o peso corporal em kg. Participaram 102 adolescentes, sendo 45 mulheres e 57 homens, entre 16 e 20 anos de idade. Resultados indicam que o fator sexo, dados antropométricos e a velocidade de execução do teste influenciam os índices de flexibilidade; a avaliação da função vertebral não pode ter como critério de normalidade atingir os pés pelo TSA, e que a velocidade rápida leva a melhores resultados. em resumo, os resultados indicam que tocar os pés, é um critério que exclui da normalidade da função vertebral aproximadamente 50% dos adolescentes. Assim, o critério para tomada de decisão quanto ao encaminhamento do adolescente para recuperação de maiores índices de flexibilidade precisa ser revisto.

Um experimento foi conduzido com o objetivo de estudar os efeitos dos níveis de cálcio nas rações sobre o desempenho e a qualidade de ovos de poedeiras comerciais. Foram utilizadas 216 poedeiras da linhagem Lohmann Brown no período de 39 a 55 semanas de idade. O delineamento utilizado foi inteiramente casualizado, composto de seis níveis de cálcio (3,0; 3,4; 3,8; 4,2; 4,6; 5,0%) e seis repetições de seis aves por parcela. Os níveis de cálcio avaliados não influenciaram os parâmetros produtivos, mas afetaram significativamente as porcentagens de albúmen e casca do ovo. O aumento do cálcio na dieta promove incremento na qualidade da casca do ovo em relação aos demais componentes do ovo. Recomenda-se nível de 4,3% de cálcio em dietas para poedeiras semipesadas após o pico de postura.

The aim of this work was to evaluate the allelopathic effect of water extract from sunflower fresh leaves on the germination and initial development of conventional and transgenic soybean cultivars, and of the invasive hairy beggartick (Bidens pilosa L.). Experiments were carried out at Laboratory of Plant Physiology, Universidade Estadual do Oeste do Parana, in 2007. Fresh leaves from sunflower were ground in a blender at the proportion 200g/1L distilled water, resulting in crude extract (100%), in which pH was measured. Dilutions of 80%, 60%, 40% and 20% were done from the crude extract, and only distilled water was used as control. Statistical analysis (Tukey 5% probability) indicated that only the highest extract concentrations (60%, 80% and 100%) influenced the analyzed parameters for conventional and transgenic soybean. Beggartick seeds, however, had germination percentage completely inhibited when 40% water extract was applied, which indicates that sunflower straw could be used as a natural herbicide. Nevertheless, field studies must be carried out to prove such effect.

The family Meliaceae has been identified as one of the most promising for biological control, as most species have biologically active compounds. Among the species, the Neem (Azadirachta indica A. Juss) is that stands out most for its efficiency and low toxicity, and it is utilized to control insects, fungi and nematodes. The aim of this work was to verify the allelopathic potential of aqueous extract of fresh leaves of Neem on germination of lettuce, soybeans, maize, beans and Bidens pilosa, as a way to control this weed. The extract was obtained by grinding 200g/L of fresh leaves of the Neem (considered extract 100%) and diluting in distilled water at concentrations of 80, 60, 40, and 20%, and a control with only water. The seeds were kept in the germination chamber at a temperature of 25 degrees C, with photoperiod of 12 hours of light. The aqueous extract affected the germination percentage and average length root of lettuce, with values of 1% and 0.1, cm respectively. For the soybeans, the extract influenced negatively the average time of germination and average speed of germination. There was a drastic reduction of the average root length at higher concentration for soybean, corn and beans. For Bidens pilosa all the parameters analyzed were negatively affected, which means sensitivity to the extract. The bioassay performed in the laboratory showed that the aqueous extract of fresh leaves of Azadirachta indica has allelopathic effect on all species.

The epic and science seem to have been the most important concerns of the Brazilian author Haroldo de Campos (1929-2003) in his last twenty years of life. The books Finismundo: a última viagem and A máquina do mundo repensada are two significant works in his aesthetical journey. This paper presents some strategies for reading both books, in which the relationship between those themes is emphasized. As a starting point, it is believed that the analogy between science and the epic does not represent a paradigm of reading on which the poetry of Harold de Campos intends to base itself, but a way of thinking about the political and literary concerns that constitute its own situation. The creation of a poetics of adventure as an alternative to the end of utopia and the affirmation of a principle of indeterminacy as a way to oppose the interpretations immediately available in the present constitute two of the main interests found in this mode of reading.
