Márcate un discurso con Cortázar

2018

Por su frecuencia de aparición y el papel que desempeñan en las inferencias pragmáticas, los marcadores del discurso resultan indispensables en la adquisición de la competencia comunicativa a la que debe aspirar todo estudiante de E/LE. Sin embargo, los docentes afrontan no pocas dificultades para trabajar con ellos, entre otras cosas porque son escasos y a menudo erráticos los materiales diseñados específicamente para enseñarlos. Con el propósito de paliar este déficit, presentamos una secuencia didáctica pensada para un nivel C1 y ensamblada como una aproximación coherente a la figura de Julio Cortázar. En el tratamiento de los marcadores discursivos adoptamos la perspectiva cognitivo-pra…

Rapid evaluation of notch stress intensity factors using the peak stress method with 3D tetrahedral finite element models: Comparison of commercial c…

2022

The peak stress method (PSM) allows a rapid application of the notch stress intensity factor (NSIF) approach to the fatigue life assessment of welded structures, by employing the linear elastic peak stresses evaluated by FE analyses with coarse meshes. Because of the widespread adoption of 3D modeling of large and complex structures in the industry, the PSM has recently been boosted by including four-node and ten-node tetrahedral elements of Ansys FE software, which allows to discretize complex geometries. In this paper, a Round Robin among eleven Italian Universities has been performed to calibrate the PSM with seven different commercial FE software packages. Several 3D mode I, II and III …

Types de temps et risque d'inondation et d'érosion en Camargue : diagnostique et prévision au 21ème siècle (1993-2100)

2010

High sea surges and waves are the two mains hydro-meteorological phenomenon associated with coastal flooding and erosion in Camargue. For the period 1993-2002, high monthly frequencies of strong surges are usually associated with high frequency of strong waves. These two phenomenons mainly occur during weather type showing a deep low pressure system over the Bay of Biscay associated with high pressure over Central Europe. The monthly frequency of such weather regime indicates the probability of occurrence of high surges and waves along Camargue's coast. During the 21st century, the frequency of this specific weather regime could stay stationary for the A1b climate change scenario.

Comparative theoretical study of the Ag–MgO (100) and (110) interfaces

1999

We have calculated the atomic and electronic structures of Ag–MgO(100) and (110) interfaces using a periodic (slab) model and an ab initio Hartree–Fock approach with a posteriori electron correlation corrections. The electronic structure information includes interatomic bond populations, effective charges, and multipole moments of ions. This information is analyzed in conjunction with the interface binding energy and the equilibrium distances for both interfaces for various coverages. There are significant differences between partly covered surfaces and surfaces with several layers of metal, and these can be understood in terms of electrostatics and the electron density changes. For complet…
