Modelo de carroceria e seu impacto sobre o bem-estar e a qualidade da carne dos suínos

O objetivo deste trabalho foi avaliar o efeito do modelo de carroceria (MC) (metálica dupla ou simples e simples de madeira) sobre a freqüência de diferentes tipos de lesões na carcaça (FLC) e sobre a qualidade da carne dos suínos. Foram utilizadas 360 fêmeas com peso vivo médio de 132,72±11,09kg. Para a análise estatística, considerou-se no modelo os efeitos de bloco (BL), o MC e a interação entre MC x BL. Verificou-se um efeito do MC sobre a freqüência de lesões na carcaça provenientes de briga e a freqüência total de lesões, sobre o pH1 do músculo Semispinalis capitis (SC), sobre o pH U dos músculos SC, Longissimus dorsi (LD) e Semimembranosus (SM) e sobre a cor dos músculos LD e SM. Suínos transportados em carroceria metálica simples apresentaram maiores valores de pH e da cor dos músculos avaliados. Conclui-se que suínos transportados em carroceria simples apresentam maior prevalência de lesões na carcaça e que o transporte dos suínos em carroceria metálica teve efeito positivo sobre os valores de pH e da cor carne.

An implicit BEM formulation to model strong discontinuities in solids

A boundary element method (BEM) formulation to predict the behavior of solids exhibiting displacement (strong) discontinuity is presented. In this formulation, the effects of the displacement jump of a discontinuity interface embedded in an internal cell are reproduced by an equivalent strain field over the cell. To compute the stresses, this equivalent strain field is assumed as the inelastic part of the total strain. As a consequence, the non-linear BEM integral equations that result from the proposed approach are similar to those of the implicit BEM based on initial strains. Since discontinuity interfaces can be introduced inside the cell independently on the cell boundaries, the proposed BEM formulation, combined with a tracking scheme to trace the discontinuity path during the analysis, allows for arbitrary discontinuity propagation using a fixed mesh. A simple technique to track the crack path is outlined. This technique is based on the construction of a polygonal line formed by segments inside the cells, in which the assumed failure criterion is reached. Two experimental concrete fracture tests were analyzed to assess the performance of the proposed formulation.

Linear analysis of building floor structures by a BEM formulation based on Reissner's theory

In this work, the plate bending formulation of the boundary element method (BEM) based on the Reissner's hypothesis is extended to the analysis of zoned plates in order to model a building floor structure. In the proposed formulation each sub-region defines a beam or a slab and depending on the way the sub-regions are represented, one can have two different types of analysis. In the simple bending problem all sub-regions are defined by their middle surface. on the other hand, for the coupled stretching-bending problem all sub-regions are referred to a chosen reference surface, therefore eccentricity effects are taken into account. Equilibrium and compatibility conditions are automatically imposed by the integral equations, which treat this composed structure as a single body. The bending and stretching values defined on the interfaces are approximated along the beam width, reducing therefore the number of degrees of freedom. Then, in the proposed model the set of equations is written in terms of the problem values on the beam axis and on the external boundary without beams. Finally some numerical examples are presented to show the accuracy of the proposed model.

A BEM formulation based on Reissner's theory to perform simple bending analysis of plates reinforced by rectangular beams

In this work, the plate bending formulation of the boundary element method (BEM), based on the Reissner's hypothesis, is extended to the analysis of plates reinforced by rectangular beams. This composed structure is modelled by a zoned plate, being the beams represented by narrow sub-regions with larger thickness. The integral equations are derived by applying the weighted residual method to each sub-region, and summing them to get the equation for the whole plate. Equilibrium and compatibility conditions are automatically imposed by the integral equations, which treat this composed structure as a single body. In order to decrease the number of degrees of freedom, some approximations are considered for both displacements and tractions along the beam width. The accuracy of the proposed model is illustrated by simple examples whose exact solution are known as well as by more complex examples whose numerical results are compared with a well-known finite element code.

Cacaso não é bem o caso do acaso

Through the reading of Lero-lero, a collection of Cacaso's poetical work, this article questions the supposition that marginal poetry has no literary value as it was created through spontaneous expression of day-to-day facts, overlooking poetical elaboration. On the contrary, Cacasós poems point towards the construction of a simulacrum of spontaneity sustained not by a formal unconcern, but by a refined language, thereby placing the so-called literary values on a tightrope. Therefore we shall examine what this might mean and its effects.
