Futebol e cultura de massa em Maracanã, adeus: onze contos de futebol: sociedade brasileira pós-64

O presente trabalho se propõe a analisar a leitura sociocultural do Brasil pós-64 feita por Edilberto Coutinho através das narrativas do livro Maracanã, Adeus e, tendo como base os postulados mais recentes da Teoria da Literatura, procurar identificar as contribuições literárias, históricas, sociológicas e antropológicas deixadas pelo autor em sua narrativa. O estudo procurará demonstrar determinadas minúcias do comportamento do brasileiro e de sua sociedade pelo viés futebolístico, pensando o futebol como Esporte Nacional e elemento dessa cultura. Procurará também apresentar mecanismos de controle social e cultural exercidos durante esse período pelos governos militares e, principalmente, a maneira escolhida pelo escritor para apresentar esse poder. Esta pesquisa privilegia o estudo das técnicas contemporâneas de escrever e das possíveis inovações estilísticas introduzidas no conjunto dos contos e busca contextualizar a escolha do autor pelo conto enquanto gênero literário. E com todo rigor científico comprovar a importância de Edilberto Coutinho no cenário literário brasileiro

Não emudecer o gesto nos/dos/com os cotidianos da Educação de Jovens e Adultos: corporeidade e dança nos currículos pensadospraticados

Esta pesquisa buscou compreender o sentirpensar nos processos de tessitura do conhecimento nos/dos/com os cotidianos da Educação de Jovens e Adultos (EJA) da Escola Municipal José Maria dos Mares Guia, por meio da investigação de práticas educativas de corporeidade e dança efetivadas no Projeto Lets Dance, durante oito anos. Assim, objetivou verificar a contribuição destas experiências para a saída das carteiras escolares, onde os indivíduos são encerrados de modo prejudicial à experimentação de ações que propiciem sua formação ampla e a emancipação social. Encontrou nessas experiências elementos que possibilitaram a identificação de traços de uma educação formalista, oferecida como compensatória, onde se elegem conteúdos a serem desenvolvidos nos quais a linguagem corporal dos sujeitos é emudecida, numa cultura de repressão ao movimento e tentativa de adestramento das emoções.

Terra da Luz: a abolição da escravidão no Ceará a partir do discurso político (1870-1888)

Este trabalho tem por objetivo compreender o processo que levou ao fim da escravidão no Ceará entre os anos de 1870 e 1888 partindo dos discursos dos políticos cearenses na Assembleia Legislativa Provincial do Ceará e na Câmara Geral dos Deputados. Tomar-se-ão por base, aqui, os anais da citada Assembleia Legislativa e os Anais da Câmara dos Deputados, observando, nas discussões do Parlamento Imperial, os posicionamentos da bancada cearense. A ideia da pesquisa é identificar e analisar os projetos elaborados com o objetivo de resolver o problema da escravidão no Brasil, atentando para os argumentos utilizados pelos políticos cearenses e identificando os fundamentos explicativos para a necessidade de pôr fim à escravidão no Ceará. A análise desses discursos permitirá uma melhor compreensão da forma como a movimentação abolicionista/emancipacionista no Ceará foi percebida pelos políticos e ajudará a entender a construção do Ceará como exemplo de patriotismo, o que ocorre paralelamente a um processo de justificação do fim da escravidão que, em última instância, construiu uma determinada representação sobre o Ceará e os cearenses.

Simultaneous determination of microcystin-LR and its glutathione conjugate in fish tissues by liquid chromatography-tandem mass spectrometry

A sensitive and selective liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous quantitative determination of microcystin-LR (MC-LR) and its glutathione conjugate (MC-LR-GSH) in fish tissues. The analytes were extracted from fish liver and kidney using 0.01 M EDTA-Na-2-5% acetic acid, followed by a solid-phase extraction (SPE) on Oasis HLB and silica cartridges. High-performance liquid chromatography (HPLC) with electrospray ionization mass spectrometry, operating in selected reaction monitoring (SRM) mode, was used to quantify MC-LR and its glutathione conjugate in fish liver and kidney. Recoveries of analytes were assessed at three concentrations (0.2, 1.0, and 5 mu g g(-1) dry weight [DW]) and ranged from 91 to 103% for MC-LR, and from 65.0 to 75.7% for MC-LR-GSH. The assay was linear within the range from 0.02 to 5.0 mu g g(-1) DW, with a limit of quantification (LOQ) of 0.02 mu g g(-1) DW. The limit of detection (LOD) of the method was 0.007 mu g g(-1) DW in both fish liver and kidney. The overall precision was determined on three different days. The values for within- and between-day precision in liver and kidney were within 15%. This method was applied to the identification and quantification of MC-LR and its glutathione conjugate in liver and kidney of fish with acute exposure of MC-LR. (c) 2007 Elsevier B.V.

Influence of polarization orientation of violet light on the diffraction efficiency of bacteriorhodopsin

When a grating is recorded in a bacteriorhodopsin film by two linear parallel polarized beams together with anauxiliary violet light, the diffraction efficiency has a dependence on the polarization orientation of the violet light as well as its intensity. A method for calculating the diffraction efficiency of gratings in bacteriorhodopsin is proposed based on the two-state photochromic model, considering the saturation effect and the polarization status of all the involved lights. It is found that the polarization orientation of the violet light produces an approximate-cosine and an approximate-sine modulation on the steady-state diffraction efficiency separately at low and high intensities, respectively. The parallel polarized violet light can improve the steady-state diffraction efficiency to a larger degree than the perpendicularly polarized violet light when both are at their optimal intensities. The optimal intensity for the parallel polarized violet light is lower than that of the perpendicular polarized one. Thus, the improvement of the steady-state diffraction efficiency is less sensitive to the intensity of perpendicular polarized violet light than to that of parallel polarized violet light.

Kinetics of photoinduced anisotropy in bacteriorhodopsin film under two pumping beams

Photoinduced anisotropy in bacteriorhodopsin (BR) film arises from the selective bleaching of BR molecules to linearly polarized light. The kinetics of photoinduced anisotropy excited by single and two pumping beams are investigated theoretically and experimentally. Compared with a single pumping beam (650 nm), which produces comparatively small photoinduced anisotropy, dual-wavelength linearly polarized pumping beams (650 and 405 nm) can obviously change the photoinduced anisotropy. When the polarization orientation of the 405 ran pumping beam is perpendicular to that of the 650 nm pumping beam, the peak and steady values of the photoinduced anisotropy kinetic curves are remarkably enhanced. But when the two pumping beams have parallel polarization orientation, the peak and steady values are restrained. At a fixed intensity of the 650 nm pumping beam, there exists an optimal intensity for the 405 nm pumping beam to maximize the value of the photoinduced anisotropy. The photoinduced transmittance of the polarizer-BR-analyzer system is modulated by the polarization angle of the 405 nm pumping beam in an approximate-cosine form.

Application of bacteriorhodopsin film for polarization phase-shifting interferometry

Photoinduced anisotropy in bacteriorhodopsin (BR) film is based on photoanisotropic selective bleaching of BR molecules under linearly polarized excitation light. It is modulated by the polarization orientation of the linearly polarized light. The anisotropic information recorded in the BR film is read by a circularly polarized light, which is in turn converted into an elliptical polarized light by the BR film. The rotation angle and the ellipticity of the elliptical polarized light are dependent on the polarization orientation of the linearly polarized excitation light. A phase-shifting interferometer based on the photoinduced anisotropy of BR film is presented theoretically and experimentally. Phase shift is controlled by the polarization orientation of the external excitation light, thus, the phase shift can be controlled without moving parts inside the interferometer, which contributes to the mechanical stability of the system.

Phase and amplitude reconstruction from a single carrier-frequency interferogram without phase unwrapping

A rapid algorithm for phase and amplitude reconstruction from a single spatial-carrier interferogram is proposed by bringing a phase-shifting mechanism into reconstruction of a carrier-frequency interferogram. The algorithm reconstructs phase through directly obtaining and integrating its real-value derivatives, avoiding a phase unwrapping process. The proposed method is rapid and easy to implement and is made insensitive to the profile of the interferogram boundaries by choosing a suitable integrating path. Moreover, the algorithm can also be used to reconstruct the amplitude of the object wave expediently without retrieving the phase profile in advance. The feasibility of this algorithm is demonstrated by both numerical simulation and experiment. (c) 2008 Optical Society of America.

Phase reconstruction from three interferograms based on integral of phase gradient

A novel algorithm of phase reconstruction based on the integral of phase gradient is presented. The algorithm directly derives two real-valued partial derivatives from three phase-shifted interferograms. Through integrating the phase derivatives, the desired phase is reconstructed. During the phase reconstruction process, there is no need for an extra rewrapping manipulation to ensure values of the phase derivatives lie in the interval [-pi, pi] as before, thus this algorithm can prevent error or distortion brought about by the phase unwrapping operation. Additionally, this algorithm is fast and easy to implement, and insensitive to the nonuniformity of the intensity distribution of the interferogram. The feasibility of the algorithm is demonstrated by both computer simulation and experiment.

This dissertation aims to study the loyalty clauses present in most of the long lasting service contracts. We introduce its main features and the consequences that arise from breaching of contract. We analyze the presence of loyalty periods in the Portuguese legislation. In this sense, we discuss Decree-Law 446/85, Law 24/96, Decree-Law 57/2008 and Decree-Law 56/2010. The loyalty period is the minimum period of time for which the contract should be maintained. In most cases, when this obligation is not fulfilled a penalty clause is set, intending to push the weaker party to comply with the contract or sanction it when the party fails to do so. We conclude that the contractual relationship where there is a loyalty period is usually an unbalanced relationship because it only protects the interest of one party. The penalty clause should not be admitted between parties with unequal bargaining powers. The contractual imbalance is not limited to consumer contracts.
