A dor que ressoa nos contos pós-64: aspectos de uma ficcionalização do testemunho

A presente dissertação enfoca as relações entre a literatura e a história, tendo por objetivo identificar e analisar os aspectos recorrentes em contos que ficcionalizam o relato da tortura ligada ao Regime Militar brasileiro de 1964. Para tanto, elegemos como corpus desta pesquisa os textos “Acudiram três cavaleiros”, de Marques Rabelo (1967); “O mar mais longe que vejo”, de Caio Fernando Abreu (1970); “Pedro Ramiro”, de Rodolfo Konder (1977); “O jardim das oliveiras”, de Nélida Piñon (1980); “Saindo de dentro do corpo”, de Flávio Moreira da Costa (1982); “O leite em pó da bondade humana”, de Haroldo Maranhão (1983); “Não passarás o Jordão”, de Luiz Fernando Emediato (1984); e “A mancha”, de Luis Fernando Veríssimo (2003). Tais narrativas apresentam como núcleo narrativo cenas de tortura relacionadas à ditadura civil-militar instalada no Brasil em 1964. Partimos da hipótese de que esses contos se apropriam de aspectos composicionais do testemunho verídico e os reelaboram esteticamente nos textos, muitas vezes, rompendo o que se teoriza sobre o testemunho verídico, na tentativa de se traduzir em palavras as aporias da rememoração do trauma provocado pela tortura. Para dar conta de tais proposições, elegeu-se como percurso a contextualização histórica realizada no primeiro capítulo, com o intuito de pontuar as relações existentes entre as produções e o contexto histórico. Em seguida, no capítulo dois, realizou-se a revisão do referencial teórico que baseia a pesquisa, centrando nas formulações propostas acerca da teoria do testemunho. Por fim, no terceiro capítulo, realizou-se a análise do corpus, com base em três aspectos recorrentes nas narrativas: a composição dos personagens, a organização da narrativa e a seleção vocabular. Para tal análise iremos nos pautar, principalmente, nas formulações de Seligmann-Silva (2003; 2008), Valeria de Marco (2004) e Elcio Loureiro Cornelsen (2011), acerca do testemunho de catástrofes históricas e da dimensão ficcional dessas produções; nas proposições de Maria Rita Kehl (2004) sobre o corpo torturado; e nas considerações de Sigmund Freud (1920), sobre trauma.

In vitro ANTIGIARDIAL ACTIVITY OF THE CYSTEINE PROTEASE INHIBITOR E-64

As cisteína-proteases estão entre os alvos mais promissores para o desenvolvimento de novos agentes terapêuticos, visto que participam de eventos fundamentais do ciclo de vida de muitos microorganismos, inclusive Giardia. Como a atividade das proteases pode ser controlada por inibidores específicos, essas substâncias têm sido avaliadas quanto ao potencial antiparasitário. Diante disso, o presente estudo teve por objetivo avaliar o efeito in vitro do inibidor de cisteína-proteases E-64 sobre o crescimento, a aderência e a viabilidade de trofozoítos de cepa de Giardia isolada em Botucatu. Nos ensaios de crescimento e aderência, o número de trofozoítos foi estimado microscopicamente em hemocitômetro, enquanto que a viabilidade celular foi avaliada pelo método do MTT. No presente estudo, embora o metronidazol tenha se apresentado bastante efetivo, o E-64 mostrou ser capaz de inibir o crescimento, a aderência e a viabilidade em taxas superiores a 50%, especialmente nos cultivos expostos à concentração de 100 µM. A despeito de preliminares, esses resultados demonstram que o inibidor E-64 pode interferir em processos primordiais para a sobrevivência do parasita, além do que, abrem novas perspectivas para investigações futuras a fim de se avaliar o real potencial giardicida dos inibidores de proteases.

Popping expansion and yield responses of popcorn cultivars under different row spacings and plant populations

The objective of this work was to evaluate the agronomic traits and the popping expansion index of three Brazilian popcorn cultivars under different row spacings and plant populations. The trials were performed during two crop seasons, under field conditions. The experimental design used was a randomized complete block, in a split-split plot, with 27 treatments and four replicates. Treatments were represented in a triple factorial arrangement: three row spacings (0.40, 0.60, and 0.80 m), three plant populations (40,000, 60,000, and 80,000 plants per hectare), and three popcorn cultivars (IAC-TC 01, IAC 12, and Zelia). The increase in plant population causes a reduction in the number of grains per ear, lower prolificacy, and grain weight loss. Cultivar grain yield is affected by row spacing and popcorn plant population. Cultivar IAC 12 shows highest grain yield under row spacings of 0.40 and 0.60 m and plant population between 60,000 and 80,000 plants per hectare. The popping expansion index is not affected by row spacing or plant population.

This text presents the first results of including research, in process, that it intends to investigate - in the period from 1950 to 1964 - the picture of the progressive political parties, the unions of the city and of the field, and the social movements marked by the national statement and for the anti-imperialism, especially those linked to the world labor perspective, discussing their proposals, differences, performances and commitments due to the political-cultural effervescence of this historical moment.

Da prescrição curricular ao currículo como ação compartilhada: dilemas das tentativas de renovação dos programas de ensino de Matemática no estado de São Paulo pós-64

The present study is the result of joint actions between education, research and outreach that is focused on the training of educators and its implications for the renovation of teaching Mathematics. Its objective is to analyze the attempts to reorganize in mathematics curriculum implemented in the state of São Paulo in the post-64. It makes use of documentary analysis and interviews of teachers for reasons of discussion and conclusions. Situated in the theoretical and methodological context of collaborative research and historical-cultural theory. The research results which shows that mathematical activity is the centrality of the discussion about learning mathematics, which has consequences for the organization, of teaching programs. This is a genesis school thinking that motivates the students to the reconstruction of ideas and thinking a production process in the classroom that considers the conditions of the school, other than the conditions that governs the production of knowledge of mathematical science, which requires thinking about the formation of a teacher epistemologically curious.

SILICON IN ROW AND NITROGEN IN TOPDRESSING FERTILIZATION ON RICE UNDER DRY LAND AND SPRINKLER IRRIGATION CONDITIONS

The objective of this work was to evaluate the effects of silicon application adjusted with nitrogen fertilization via top-dressing on grain productivity, the silicon contents of the soil, in the plant tissue and nitrogen contents in dry and irrigated conditions. The experimental outlining was from designed blocks with subdivided parcels and four repetitions. The treatments consisted of culture system (dry and irrigated) and the under parcels by the combination of silicon (0 and 100 kg ha(-1)), in magnesium and calcium silicate form (with 23% of SiO2), and four doses of N (urea) via top-dressing (0, 30, 60 and 90 kg ha(-1)). Silicon application at sowing furrow was a viable technique because it provided significant increase in the content of this element in the root growth of rice. The application of silicon in the sowing furrow did not change the content of the element nor the nitrogen nutrition in rice plants. The nitrogen application reduced the silicon content and increased nitrogen nutrition in rice plants. Silicon application at sowing furrow provided no increase in rice grain yield. When there was no water limitation to nitrogen fertilization enhanced linearly on rice grain yield, whereas under water stress the effect of nitrogen fertilization was limited.

Metal binding selectivity of oxa-aza macrocyclic ligand: a DFT study of first- and second-row transition metal for four coordination systems

A detailed theoretical study of the 1,7,1l,17-tetraoxa-2,6,12,16-tetraaza-cycloeicosane ligand ([20]AneN(4)O(4)) coordinated to Fe2+, Co2+, Ni2+, Ru2+, Rh2+, and Pd2+ transition metal ions was carried out with the B3LYP method. Two different cases were performed: when nitrogen is the donor atom (1a (q) ) and also with the oxygen as the donor atom (1b (q) ). For all the cases performed in this study 1a (q) structures were always more stable than the 1b (q) ones. Considering each row is possible to see that the energy increases with the increase of the atomic number. The M2+ cation binding energies for the 1a (q) complexes increase with the following order: Fe2+ < Ru2+ < Co2+ < Ni2+ < Rh2+ < Pd2+.

First- and second-row transition metal oxa-aza macrocyclic complexes: a DFT study of an octahedral conformation

A theoretical study of structures of the 1,7,1 l,17-tetraoxa-2,6,12,16-tetraaza-cycloeicosane ligand ([20]AneN(4)O(4)) coordinated to Fe2+, Co2+, Ni2+, Ru2+, Rh2+, and Pd2+ transition metals ions was carried out with the DFT/B3LYP method. Complexes were fully optimized in C-s symmetry with the metal ions coordinated either to nitrogen (1a) or oxygen atoms (1b). For all the cases performed in this work, 1a was always more stable than 1b. Considering each row it is possible to see that the binding energy increases with the atomic number. The M2+ cation binding energies increase in the following order: Fe2+ < Ru2+ < Co2+ < Ni2+ < Rh2+ < Pd2+. In addition, it was observed the preference of Pd2+ and Rh2+ complexes for a tetrahedral arrangement, while Fe2+, Ru2+, Co2+, Ni2+ complexes had a preference for the octahedral arrangement. From the orbital representation results, it was seen that 1b unsymmetrical orbitals may influence the susceptibility over metal ions orientation toward heteroatoms orbitals.

Hepatobiliary diseases in small animals: a comparison of ultrasonography and multidetector-row computed tomography

Ultrasonography (US) is an essential imaging tool for identifying abnormalities of the liver parenchyma, biliary tract and vascular system. US has replaced radiography as the initial imaging procedure in screening for liver disease in small animals. There are few reports of the use of conventional and helical computed tomography (CT) to assess canine or feline parenchymal and neoplastic liver disease and biliary disorders. In human medicine the development of multidetector- row helical computed tomography (MDCT), with its superior spatial and temporal resolution, has resulted in improved detection and characterization of diffuse and focal liver lesions. The increased availability of MDCT in veterinary practice provides incentive to develop MDCT protocols for liver imaging in small animals. The purpose of this study is to assess the rule of MDCT in the characterization of hepatobiliary diseases in small animals; and to compare this method with conventional US. Candidates for this prospective study were 175 consecutive patients (dogs and cats) referred for evaluation of hepatobiliary disease. The patients underwent liver US and MDCT. Percutaneous needle biopsy was performed on all liver lesions or alterations encountered. As for gallbladder, histopatological evaluation was obtained from cholecystectomy specimens. Ultrasonographic findings in this study agreed well with those of previous reports. A protocol for dual-phase liver MDCT in small animals has been described. MDCT findings in parenchymal disorders of the liver, hepatic neoplasia and biliary disorders are here first described in dogs and cats and compared with the corresponding features in human medicine. The ability of MDCT in detection and characterization of hepatobiliary diseases in small animals is overall superior to conventional US. Ultrasonography and MDCT scanning, however, play complementary rules in the evaluation of these diseases. Many conditions have distinctive imaging features that may permit diagnosis. In most instances biopsy is required for definitive diagnosis.
