A computational study of some electric and magnetic properties of gaseous BF3 and BCl3
2005
We present the results of an extended computational study of the electric and magnetic properties connected to Cotton-Mouton birefringences, on the trifluoro- and trichloroborides in the gas phase. The electric dipole polarizabilities, magnetizabilities, quadrupole moments, and higher-order hypersusceptibilities—expressed as quadratic and cubic frequency-dependent response functions—are computed within Hartree-Fock, density-functional, and coupled-cluster response theories employing singly and doubly augmented correlation-consistent basis sets and London orbitals in the magnetic property calculations. The results, which illustrate the capability of time-dependent density-functional theory f…
Vers le contrôle de l'alignement et de l'orientation : théorie et expérience
2010
This thesis is about the control and characterisation of the alignment and orientation of molecules by ultra short laser pulses on a theoretical and experimental approach. Alignment corresponds to a symmetric angular distribution of the molecular axis peaked along the laser field axis, whereas orientation provides an asymmetric distribution favouring one spatial direction. Orientation by sudden two-colour (2+1) pulses is studied extensively for the non resonant case and conditions required for achieving significant orientation are explored. A second two-colour scheme, where the second harmonic is in quasi resonance with a vibrational level of the molecule, is also presented and discussed. T…
Territorial tripolarization in Bolivia : genesis and current situation
2012
The Bolivian urban system is outstanding : three major cities concentrate about half of the nation’s population and employment. Their territories’ trajectories lead us to question their economic role in the face of the successful economic achievement of Potosi and Tarija, territories well endowed in natural resources. We wanted to highlight the Bolivian current territorial tripolarization, firstly by studying its emergence, through the study of their economical history; secondly, by investigating the most recent economical data in order to display the strengths and weaknesses of this tripolarized system. Each component of the tripole is situated in a different geographical setting. In the W…
“The war is over”. Militarizing the language and framing the Nation in post-Brexit discourse
2020
This chapter analyzes the militarization of political language in digital contexts in the post-Brexit discourse, and how such militarization, which is often constitutive of hate speech, contributes to framing an “exclusive” concept of the nation whose meaning is reproduced and circulated (as well as challenged) in society. It will address the role of emotions and hate in language in fueling and aggregating online communities around a key political issue, i.e. the Brexit negotiations, and a core cultural and social concept, i.e. the nation. The militarization of language, which is based on certain discursive structures, e.g. war metaphors (Lakoff and Johnson 1980, Musolff 2020), is one of th…
Butor, Mondrian et la fragmentation de l’espace: parcours génétique d’un roman-laboratoire
2018
Passage de Milan est sans aucune doute le chantier où Butor commence à travailler sur la forme du roman qui trouve son contrepoint théorique dans les essais publiés juste après sa parution. Parmi les épisodes qui se trouvent en relation métonymique avec le roman, c’est par la description du tableau de Martin De Vere, claire allusion au néoplasticisme de Mondrian, que Butor nous donne une représentation à échelle réduite de l’édifice et de ses habitants. Ce tableau inachevé où tous les éléments sont provisoires n’est que l’image du roman en gestation qui s’écrit au fur et à mesure que la narration avance. Les phases d’élaboration de cet épisode permettent d’éclaircir la technique de fragment…
Effect of two novel bio-based rejuvenators on the performance of 50% RAP mixes - a statistical study on the complex modulus of asphalt binders and as…
2019
An experimental study was conducted to evaluate the effectiveness of two bio-additives as rejuvenators on the properties of asphalt mixtures containing 50% RAP and their binder constituents containing 37% RAP binder. Before mixing, the rejuvenators were blended with fresh bitumen and the extracted and recovered RAP bitumen, and changes in the rheological properties of the binders were assessed using performance grading (PG) criteria. The results showed that both rejuvenators could improve the low-temperature performance of the aged RAP binder and restore its low-temperature properties. Master curves for the unaged, RTFO-aged, and PAV aged blends were constructed using both the Christensen-A…

Démocratisation de l'enseignement supérieur et emprise des parcours
2014
This article looks at how the organization of the education system and the pathways leading to higher education enable social mobility or on the contrary the reproduction of inequalities. We thus compare three countries: France, Switzerland, and Canada. The results using panel data in these three countries show two different situations. The more higher education is valued rather than vocational training, the more inequalities tend to increase. The competition is such that it is the youth with a privileged social background who benefit more from its expansion. On the other hand, when the vocational education and training is more valued, inequalities in higher education could tend to be more …
