Between 1894 and 1899 Kate Chopin (1850 – 1904), one of the main exponents of American Realism and Feminism, published seven critical essays in newspapers and journals. To this number, it might be added the sketch ―Confidences‖ and the two first entrances of Impressions, her second diary, totalizing nine texts. These texts unveil a refined critical spirit, an outspoken and edge-cutting style in writing, sometimes sarcastically merciless, and an eager reader, all of them aspects that would be put into practice by the Feminist criticism expressed in the author‘s novels and short stories. To introduce and briefly discuss these essays are the main purposes of this paper.

Once the choices set involved in the selection of compositional techniques of a photography is mediated by ideological universes, this final project aims to analyze the photographic coverage of the World War II presented in the brazilian publication Revista da Semana during the period in which Brazil was part of the conflict (1942 to 1945). We study the different composition techniques used and the different effects of meaning articulated by these techniques. Thus, our goal is to see how the repetitions are articulated and the translations of meaning in photojournalistic composition from its narrative structure, that is, their way of coded organization. For this, we used the analysis methodology proposed by Umberto Eco on the rhetoric of the image, involving the five levels of photography decomposition (ie iconic levels, iconographic, tropological, topic and enthymematic). We will analyze these images from the perspective of the effects of meaning that the composition techniques to engender glimpse which were woven meanings to this event in that specific space, and which were mediated discourses of Brazilian participation in the conflict

In this paper it was evaluated the influence of the relative position of logs on the trees, the type of wood (juvenile and mature wood and pith) and the dimension of sawed wood elements on the velocity of propagation of stress waves into the material on condition. P. taeda L wood (43 years old trees) from Horto Florestal of Manduri (latitude 230 00’ south, longitude 400 19’ west and altitude de 700 m) São Paulo State, Brazil were used, considering its easy growth rings visualization and the better ju regions definition. Six trees were randomly chosen in the plantation. Trees were sawed into 4 logs (2,5 m long each. In each log it was delimited the central board (80mm tick) region and the lateral boards (25mm tick) regions, cons right hand. It were evaluated relation between velocity of stress waves on logs and the correspondent lumber (central and lateral boards), on green condition, on the three main region of the elements (mature wood results obtained revealed the concordance between velocities of stress waves in the material before and after the its mechanical processing. It was also revealed statistical differences between the velocity of stress waves at juvenile wood, mature wood and pith regions.

P. taeda L., originária de árvores de plantio do Horto Florestal de SP., com idade aproximada de 43 anos, pela facilidade de identificação dos anéis imento e demarcação das regiões de madeira adulta e madeira juvenil. Foram amostradas 6 árvores distintas, escolhidas ao acaso do talhão selecionado. De cada árvore foram retiradas 4 toras com comprimento de 2,5 m cada. Foram demarcadas nas toras a ha central (8 cm de espessura) e 4 tábuas laterais (espessura comercial de 2,5 cm), sendo duas à esquerda e duas à direita da prancha central. Foram avaliadas as relações existentes entre as velocidades de propagação das ondas de tensão na madeira íntegra (toras) e desdobrada (pranchas e tábuas), na condição de madeira verde, nas três regiões distintas do lenho: medula, madeira adulta e madeira juvenil. A análise comparativa dos resultados revelou a concordância entre as velocidades antes e após o desdobr madeira. Houve diferenciação estatisticamente significativa entre as velocidades de propagação das ondas de tensão nos lenhos adulto, juvenil e na medula. -destrutivos, método das ondas de tensão, Pinus taeda stress wave tests on green logs and lumber of Pinus taeda In this paper it was evaluated the influence of the relative position of logs on the trees, the type of wood (juvenile and mature wood and pith) and the dimension of sawed wood elements on the velocity of propagation of stress waves into the material on L wood (43 years old trees) from Horto Florestal of Manduri (latitude 19’ west and altitude de 700 m) São Paulo State, Brazil were used, considering its easy growth rings visualization and the better juvenile and mature wood regions definition.
