William Gaddis’s The Recognitions (1955) is a selfreflexive novel that portrays Wyatt Gwyon’s trajectory from childhood to maturity, as he rejects and searches for originality. The present work bestows an analysis of William Gaddis’s The Recognitions focusing on the problematization of originality and authorship proposed by the novel by means of the central issues of forgery and plagiarism, which bring with them two larger and more important sister-notions: authorship and originality. The novel questions the prevailing demand for originality and discusses the possibility of being original. It formulates an aesthetics of recognitions defended in the novel and used by the author in the making of this text. In order to do that, this work provides a view on the different concepts associated with the terms originality and original, as well as some of the main infringements related to them in contemporary society. It also offers an account of the development of the concepts of originality and authorship in Western society, showing the growing importance of the figure of the author and the parallel development of the concepts of plagiarism and copyright. The next three chapters are dedicated to attempt to provide an account of William Gaddis’s The Recognitions focusing on the main artist characters and an analysis of the novel in the light of the theoretical and historical background provided. The first of these chapters focuses on Wyatt’s trajectory and his visions of art. The second identifies and analyses Wyatt’s mirrors in the narrative, which reinforce the self-reflective structure of the novel. And the third chapter exemplifies and analyses Wyatt’s aesthetics of recognitions, which turns out to be Gaddis’s own aesthetics in the making of his fiction.

A imagem mítica de perfeição dos apresentadores do Jornal Nacional – Rede Globo de Televisão – construída pela mídia é o enfoque central desta pesquisa. Tanto no âmbito das soft quanto das hard news de revistas, jornais e sites de informação, Fátima Bernardes e William Bonner são estruturados como um casal pleno na profissão, no amor e nas relações familiares. É no imbricamento entre jornalismo e pensamento mítico que se torna possível essa leitura, revelando uma forte presença do imaginário cultural na pretensa objetividade jornalística. Usando conceitos de análise do discurso como suporte, analisamos 168 textos ao longo de um período de seis anos (1998 a 2004), apontando como a mídia constrói essa imagem e que sentidos mobiliza ao imputar ao casal um lugar privilegiado no panteão de celebridades da cultura de massa. A pesquisa está estruturada em três formações distintas: a) amor, fama e beleza; b) trabalho, sucesso e predestinação; c) família e moral. Mais do que jornalistas, os apresentadores do telejornal são retratados como estrelas de moral impecável, diferentemente das celebridades vulgares e sem predicados presentes na mídia atual.

This work presents the structure and ultrastructure of the interrenal gland and chromaffin cells, as well as the morphology of the head kidney of Brycon cephalus, the head kidney is composed of fused bilateral lobes located anterior to the swim bladder and ventrolateral to the spinal column, the parenchyma revealed lympho-haematopoietic tissue, melano-macrophage centres, interrenal gland and chromaffin cells. The interrenal gland consisted of cords or strands of cells grouped around the posterior cardinal vein and their branches. Chromaffin cells are found in small groups, closely associated with the interrenal gland and/or under the endothelium of the posterior cardinal vein. So far, the ultrastructural analysis has revealed only one interrenal cell type which contained abundant smooth endoplasmic reticulum and numerous mitochondria with tubulo-vesicular cristae, characteristic of steroid-producing cells. Two types of chromaffin cells were observed. The first type was characterized by the presence of vesicles with round, strongly electron-dense granules, which were eccentrically located, Such cells were interpreted as noradrenaline cells, Meanwhile, cells which contained smaller vesicles and electron-lucent granules, with a small halo separating the granule from the vesicular limiting membrane, were identified as adrenaline cells.

O presente trabalho teve como objetivo avaliar a influência da adubação da cultura do sorgo Sorghum bicolor (L.) Moench, na biologia da broca da cana-de-açúcar Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Pyralidae). Para isso foi utilizado sorgo da cultivar Rubi-Asgrow, plantado em vasos utilizando-se diferentes doses de fertilizantes e mantidos em casa-de-vegetação. Os tratamentos utilizados (doses de NK) foram: N1 = 0-200 ppm; N2 = 50-200 ppm; N3 = 100-200 ppm; N4 = 200-200 ppm; N5 = 400-200 ppm; K1 = 200-0 ppm; K2 = 200-50 ppm; K3 = 200-100 ppm; K4 = 200-200 ppm; e K5 = 200-400 ppm. de modo geral, pode-se concluir que doses de 50 a 200 ppm de N promoveram o desenvolvimento normal das larvas de D. saccharalis, sendo que as menores porcentagens de dano foram verificadas nas menores doses; para o potássio, quanto maior a dose, menor foi o dano causado pelas lagartas, apesar de favorecer o desenvolvimento da mesma.

The objective of this work was to evaluate biological aspects of Diatraea saccharalis fed on artificial diet containing different concentrations of the Sudan B Red dye and the possibility to mark the parasitoid Cotesia flavipes, when submitted to the parasitism of dyed caterpillars. For that, were added to the artificial diet four concentrations of Sudan Red B dye (100, 200, 300 and 400 ppm) and control (no dye addition). It was evaluated larval and pupal period, larval and pupal viability, longevity, sex rate, pupal weigh, eggs per female, eggs per day, number of eggs per egg mass, egg viability and embrionary period; besides same were accomplished measurements in the caterpillars (bioassay I). Caterpillars of 17 days old (30) of each treatment were removed from the tubes and exposed to the parasitism of C. flavipes (bioassay 2). The egg-pupae period, sex rate, pupal period and viability, number of females, males, total of emerged adults and longevity were evaluated. The data were submitted to the multivariate analisys methods: cluster analysis, two-way and principal component analysis. Based on analysis, it was observed that the treatment of 100 ppm was the least harmful to the biology of the sugar cane borer larvae by groping to the control and did not influence negatively its biological aspects. The concentration of 400 ppm affected negatively the biology of C. flavipes. The Sudan Red B it is ended doses marked the caterpillars and the adults, however the concentration of 100 ppm is the most suitable to dye D. saccharalis. None of the tested concentration marked adults of C. flavipes, despite to affect negatively its biology. It is unviable to increase the concentration seeking futures tests, for that dye to be harmful to the biological aspects of D. saccharalis and C. flavipes.

This study evaluated stress indicators of juvenile piau (Leporinus friderici) during and after a 4-hour transportation in order to establish an appropriate transportation protocol for this type of fish. Fish were transported in plastic bags (133.1 g/L) and sampled before loading, during 1, 2, 3 and 4 h and after transportation (2, 6, 12 and 24 h). Blood samples were analyzed for cortisol and glucose levels, hematocrit, hemoglobin level, number and mean corpuscular volume of erythrocytes. Water pH, dissolved oxygen, temperature and ammonia were monitored before, during and after transportation. No mortality was observed through the experiment. Ammonia levels increased throughout transportation, but the low pH values kept NH3 in safe levels for fish. Cortisol levels increased within 4 h of transportation, and returned to control condition 2 h after arrival. Plasma glucose increased within one hour of transportation, reaching peak value within 4 h and returning to initial condition 2 h after arrival. Erythrocyte number and hemoglobin levels showed the lowest levels 2 h after arrival, and mean corpuscular volume increased during transportation, decreasing at 12 and 24 h after arrival. Transporting piau is stressful, but fish recover the initial condition in short time, showing tolerance to the changes in the water quality parameters.

O matrinxã, Brycon cephalus, espécie nativa oriunda da Bacia Amazônica, apresenta características adequadas para a piscicultura. Entretanto, trata-se de peixe reofílico, sendo necessário manejo adequado para induzir à reprodução. O objetivo deste trabalho foi caracterizar o perfil da triiodotironina (T3) plasmática no matrinxã, durante 16 meses (outubro/97 a janeiro/99), relacionando-o com a maturação sexual, além de testar a ação do T3 associado ao extrato pituitário de carpa na reprodução induzida da espécie. O experimento foi conduzido no Centro Nacional de Pesquisa de Peixes Tropicais - CEPTA, Pirassununga, SP, e no Departamento de Morfologia e Fisiologia Animal, da Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal - UNESP. Foram amostrados, mensalmente, 8 a 12 peixes, de ambos os sexos, totalizando 173 animais, de onde retirou-se sangue para dosagem do T3 plasmático. As gônadas foram removidas para análise histológica com identificação do sexo e determinação do estádio de maturação. Analisaram-se testículos e ovários de 161 peixes em corte transversal, tendo predominado machos (63,35%) e o estádio sexual imaturo entre ambos. A concentração plasmática de T3 foi maior de dezembro a janeiro, para machos e fêmeas, coincidindo com o período de maior atividade reprodutiva da espécie e maiores temperaturas da água. em janeiro/99, reprodutores de matrinxã foram induzidos com extrato de pituitária de carpa (EPC) associado à administração de T3 (20 mg/kg em 0,1 mL de suspensão oleosa). Os resultados sugeriram que o T3 atuou sinergicamente à gonadotropina do extrato hipofisário e que o tratamento agudo de triiodotironina com o EPC pode estimular o eixo hipotálamo-hipófise-ovário. O tempo de eclosão das larvas provenientes das fêmeas tratadas com o T3 foi menor e o crescimento inicial e a sobrevivência dessas larvas, maiores.

Although insects lack the adaptive immune response of the mammalians, they manifest effective innate immune responses, which include both cellular and Immoral components. Cellular responses are mediated by hemocytes, and Immoral responses include the activation of proteolytic cascades that initiate many events, including NO production. In mammals, nitric oxide synthases (NOSs) are also present in the endothelium, the brain, the adrenal glands, and the platelets. Studies on the distribution of NO-producing systems in invertebrates have revealed functional similarities between NOS in this group and vertebrates. We attempted to localize NOS activity in tissues of naive (UIL), yeast-injected (YIL), and saline-injected (SIL) larvae of the blowfly Chrysomya megacephala, using the NADPH diaphorase technique. Our findings revealed similar levels of NOS activity in muscle, fat body, Malpighian tubule, gut, and brain, suggesting that NO synthesis may not be involved in the immune response of these larval systems. These results were compared to many studies that recorded the involvement of NO in various physiological functions of insects.

The morphometric study of the midgut in Diatraea saccharalis (Lepidoptera) larvae parasitized by the Cotesia flavipes (Hymenoptera) showed that there was significant increase in the columnar, goblet and regenerative cells and their nuclei; the midgut lumen diameter and the epithelial height were also increased in the parasitized larvae. The multivariate analysis showed that parasitism affected the columnar cell only in the posterior region, and the goblet cells along the midgut length (anterior and posterior regions).

The goal of this work was to examine the occurrence of brachyurans in soft bottom sublittoral habitats and their association with some environmental factors. The relative abundance of crabs in two depth strata (from 4.5 to 9 m and from 9 to 18 m) was quantified. Crabs were collected with an otter-trawl with 3.7 m of mouth opening and 12-mm mesh in the cod end. Monthly sampling, consisted of a single trawl in each stratum during a 1-yr period, were carried out. Fifteen brachyuran and six anomuran species were found, including Callinectes ornatus Ordway, 1863; Callinectes danae Smith, 1869; Hepatus pudibundus (Herbst, 1785); Libinia spinosa H. Milne-Edwards, 1834; Persephona punctata (Linnaeus, 1758), and P. mediterranea (Herbst, 1794), which were the most abundant and frequent in the area. The most abundant swimming crabs in both strata were C. ornatus and C, dan(re. Size differences in C. ornatus were observed between strata, suggesting a spatial separation of juveniles and adult crabs.
