Metaphor and foreign language teaching

This article gives special attention to how the understanding of some conceptual metaphors which are found in languages typologically different can contribute to the process of teaching and learning vocabulary. Our central issue is that man's philogenetical and ontogenetical history play an important role in the generation of the concepts. If it is possible to explain cross...

Measurement and Prediction of Phase Transformation Kinetics in a Nuclear Steel During Rapid Thermal Cycles

Accurate prediction of the residual stress distributions in steel welds can only be achieved if consideration is given to solid-state phase transformation behavior. In this work, we assess the ability of a model for reaction kinetics to predict the phase transformations, and corresponding evolution of volumetric strain, in a nuclear pressure vessel steel when subjected to rapid...

Percepção visual de contraste em humanos: evidência psicofísica para canais de freqüência angular alta

The aim of this study was to measure narrow-band frequency response curves for four angular frequency filters. The test frequencies were 32, 48, 64 and 96 cycles/360º. Six humans observers with normal or corrected visual acuity measured nine curves for each filter, with a supra-threshold response summation psychophysical method allied with a forced-choice method. The results...

Objeto da epidemiologia e nós

This study examines some epistemological marks of the epidemiology's historical constitution, giving special emphasis to the process of scientific formalization (18th and 19th centuries). The reflection presented here tries to bring back, within the concrete development of the theoretical appre-hension of health's public space, the techno-social consubstantiation of the...

Use of direct and iterative solvers for estimation of SNP effects in genome-wide selection

The aim of this study was to compare iterative and direct solvers for estimation of marker effects in genomic selection. One iterative and two direct methods were used: Gauss-Seidel with Residual Update, Cholesky Decomposition and Gentleman-Givens rotations. For resembling different scenarios with respect to number of markers and of genotyped animals, a simulated data set divided...

On the global behavior of <img width=404 height=28 id="_x0000_i1030

In this paper we consider the system of piecewise linear difference equations in the title, where the initial conditions x0 and y0 are real numbers. We show that there exists a unique equilibrium solution and exactly two prime period-3 solutions, and that except for the unique equilibrium solution, every solution of the system is eventually one of the two prime period-3 solutions.

Large \(N\) scaling and factorization in \({\mathrm {SU}}(N)\) Yang–Mills gauge theory

The large \(N\) limit of \({\mathrm {SU}}(N)\) gauge theories is well understood in perturbation theory. Also non-perturbative lattice studies have yielded important positive evidence that ’t Hooft’s predictions are valid. We go far beyond the statistical and systematic precision of previous studies by making use of the Yang–Mills gradient flow and detailed Monte Carlo...
