Field-free one-dimensional alignment of ethylene molecule
2006
International audience; We report an experimental study of non-adiabatic laser-induced molecular alignment of ethylene (C2H4) using a linearly polarized short laser pulse of moderate intensity. The information about the confinement of the C=C bond axis along the direction of the applied electric field is obtained by measuring the depolarization of a second short pulse of weak intensity interacting with the molecules after they have been exposed to the first pulse. The experimental data are compared with the numerical simulation of the Schr¨odinger equation written for the non-resonant interaction of an asymmetric top rigid rotor with a linearly polarized electric field. The field-free align…
Comparaison de deux méthodes de correction atmosphérique des données thermiques de Landsat TM
1996
The high resolution of Landsat Thematic Mapper (TM) thermal infrared data can be interesting in applications such as energy balance and crop water stress studies. However, surface temperature measurements are strongly affected by atmospheric effects, particularly by water vapour absorption, therefore a correction method is absolutely necessary. The impossibility of applying a split-window equation and the difficulty of having temporarily coincident radiosondes produce a slight use of Landsat TM data to obtain surface temperature. Vidal et al. show that in a zone with homogeneous climatic conditions, atmospheric correction can be evaluated by using energy balance equation and standard meteor…
Flexibilité du contrôle moteur dans les mouvements complexes dirigés
2011
The main objective of this thesis is to study the motor flexibility in complex movements when an unexpected event makes the initial motor plan inefficient. In this way, three kinematic and electromyographic studies and a fourth with functional magnetic resonance imaging were realized. (1)The main result of the first study clearly demonstrate that during complex movements express motor corrections in the upper and lower limbs, with latency responses of less than 100 ms, were revealed by contrasting electromyographic activities in perturbed and unperturbed trials. Such findings could indicate that visual on-going movement corrections may be accomplished via fast loops at the level of the uppe…

Blessures et sentiments : les poèmes de Sinéad Morrissey
2018
This paper explores the poetry of Sinéad Morrissey (born in Portadown, Northern Ireland, in 1972), one of the most highly regarded of the younger generation of contemporary Irish poets. Taking into account her six collections to date – including There Was Fire in Vancouver (1996), The State of the Prisons (2005), Parallax (2013) and On Balance published in 2017, it examines the great variety of poetical strategies – analogy, metaphor, polysemy, play on form and perspective, pictorialism and iconicity, ekphrasis, etc. – that Morrissey uses to tell of most personal experiences (physical pain, exile, loss, pregnancy and motherhood, confrontation with forms of otherness, states of imprisonment,…
