A palavra como arma : análise do discurso do Deputado Mário Covas

Analisa o pronunciamento do Deputado Mário Covas, em dezembro de 1968, em defesa da imunidade parlamentar e da liberdade de palavra, principais ingredientes dos regimes democráticos. Utilizando as propostas formuladas por Norman Fairclough, Patrick Charaudeau e Tereza Halliday, reconstituem-se elementos caracterizadores da enunciação e os principais recursos discursivos utilizados.

Lattice instability at a fast moving crack tip

A molecular dynamics method is used to analyze the dynamic propagation of an atomistic crack tip. The simulation shows that the crack propagates at a relatively constant global velocity which is well below the Rayleigh wave velocity. However the local propagation velocity oscillates violently, and it is limited by the longitudinal wave velocity. The crack velocity oscillation is caused by a repeated process of crack tip blunting and sharpening. When the crack tip opening displacement exceeds a certain critical value, a lattice instability takes place and results in dislocation emissions from the crack tip. Based on this concept, a criterion for dislocation emission from a moving crack tip is proposed. The simulation also identifies the emitted dislocation as a source for microcrack nucleation. A simple method is used to examine this nucleation process. (C) 1996 American Institute of Physics.

A general theory on media with randomly distributed inclusions .1. The average field behaviors

In this paper, a theory is developed to calculate the average strain field in the materials with randomly distributed inclusions. Many previous researches investigating the average field behaviors were based upon Mori and Tanaka's idea. Since they were restricted to studying those materials with uniform distributions of inclusions they did not need detailed statistical information of random microstructures, and could use the volume average to replace the ensemble average. To study more general materials with randomly distributed inclusions, the number density function is introduced in formulating the average field equation in this research. Both uniform and nonuniform distributions of inclusions are taken into account in detail.

Two-time scales inner solutions and motion of a geostrophic vortex

Based on the authors' previous work, in this paper the systematical analyses on the motion and the inner solutions of a geostrophic vortex have been presented by means of thematched asymptotic expansion method with multiple time scales (S/gh001/2 and α S/gh001/2) and space scales. It has been shown that the leading inner solutions to the core structure in two-time scales analyses are identified with the results in normal one-time scale analyses. The time averages of the first-order solutions on short time variable τ are the same as the first-order solutions obtained in one normal time scale analyses. The geostrophic vortex induces an oscillatory motion in addition to moving with the background flow. The period, amplitude andthe deviation from the mean trajectory depend on the core structure and the initial conditions. The velocity of the motion of vortex center varies periodically and the time average of the velocity on short time variable τ is equal to the value of the local mean velocity.

Naive asymptotic expansion of the water wave generated by a slowly moving body

It is pointed out that the naive asymptotic expansion does not satisfy all the body boundary condition. A nonhomogeneous body boundary condition is obtained from this expansion. It is this condition that the additional wave term must satisfy. Moreover, because of this condition, the wave term must appear. It is pointed out that the zeroth approximation in the naive asymptotic expansion has weak singularity and the singularities become still stronger in the subsequent approximations.

A palavra como arma : análise do discurso do deputado Mário Covas em defesa da imunidade parlamentar

Questionada em momentos críticos, a imunidade parlamentar é uma das condições essenciais para o bom funcionamento do Legislativo. É isso que se argumenta no pronunciamento do Deputado Mário Covas, de 12 de dezembro de 1968, escolhido por nós para análise por ser um marco na defesa da imunidade parlamentar. O estudo parte de uma leitura do contexto histórico do pronunciamento e de algumas propostas de análise de discurso formuladas por Norman Fairclough, Patrick Charaudeau e, de análise retórica, por Tereza Lúcia Halliday, além da tradição aristotélica. A análise do pronunciamento reconstitui os elementos caracterizadores da enunciação - os antecedentes imediatos, a composição da audiência e o ritual daquela reunião legislativa - e os principais recursos discursivos utilizados - a estrutura do texto, a composição estilística e o ethos do orador. Ao final do trabalho, demonstra-se a importância de garantir a liberdade de palavra, de opiniões e votos, principal ingrediente de qualquer regime democrático.
