Abstract

Desde fevereiro de 1942, navios mercantes brasileiros eram torpedeados por submarinos alemães. No entanto, com o rompimento de relações diplomáticas do Brasil com a Alemanha e a Itália, o governo nazista tomou a decisão de retaliar o governo Vargas. Para o litoral brasileiro foi enviado o submarino U-507. Em agosto daquele ano, em apenas três dias, cinco navios brasileiros foram afundados, resultando na morte de centenas de homens, mulheres e crianças. O artigo tem por objetivo conhecer, ainda que parcialmente, o sofrimento dos brasileiros que, a bordo dos navios, sobreviveram aos ataques do submarino alemão, a dor daqueles que perderam seus familiares e as repercussões da agressão militar alemã na sociedade brasileira

26. High-order coupling of shear and sonic continua in JET plasmas

Abstract

A recent model coupling the shear-Alfv\'{e}n and acoustic continua, which depends strongly on the equilibrium shaping and on elongation in particular, is employed to explain the properties of Alfv\'{e}nic activity observed on JET plasmas below but close to the typical frequency of toroidicity-induced Alfv\'{e}n eigenmodes (TAEs). The frequency gaps predicted by the model result from high-order harmonics of the geodesic field-line curvature caused by plasma shaping (as opposed to lower-order toroidicity) and give rise to high-order geodesic acoustic eigenmodes (HOGAEs), their frequency value being close to one-half of the TAEs one. The theoretical predictions of HOGAE frequency and radial location are found to be in fair agreement with measurements in JET experiments, including magnetic, reflectometry and soft x-ray data. The stability of the observed HOGAEs is evaluated with the linear hybrid MHD/drift-kinetic code CASTOR-K, taking into account the energetic-ion populations produced by the NBI and ICRH heating systems. Wave-particle resonances, along with drive/damping mechanisms, are also discussed in order to understand the conditions leading to HOGAEs destabilization in JET plasmas., Comment: 10 pages, 11 figures, accepted for publication

31. Mixed finite element method for a beam equation with the p-biharmonic operator

Abstract

In this paper, we consider a nonlinear beam equation with the p-biharmonic operator, where $1 < p < \infty$. Using a change of variable, we transform the problem into a system of differential equations and prove the existence, uniqueness and regularity of the weak solution by applying the Lax-Milgram theorem and classical results of functional analysis. We investigate the discrete formulation for that system and, with the aid of the Brouwer theorem, we show that the problem has a discrete solution. The uniqueness and stability of the discrete solution are obtained through classical methods. After establishing the order of convergence, we apply the mixed finite element method to obtain an algebraic system of equations. Finally, we implement the computational codes in Matlab software and perform the comparison between theory and simulations.
