Numerical study of the Kadomtsev–Petviashvili equation and dispersive shock waves
2018
A detailed numerical study of the long time behaviour of dispersive shock waves in solutions to the Kadomtsev-Petviashvili (KP) I equation is presented. It is shown that modulated lump solutions emerge from the dispersive shock waves. For the description of dispersive shock waves, Whitham modulation equations for KP are obtained. It is shown that the modulation equations near the soliton line are hyperbolic for the KPII equation while they are elliptic for the KPI equation leading to a focusing effect and the formation of lumps. Such a behaviour is similar to the appearance of breathers for the focusing nonlinear Schrodinger equation in the semiclassical limit.

Numerical study of blow-up and stability of line solitons for the Novikov-Veselov equation
2017
International audience; We study numerically the evolution of perturbed Korteweg-de Vries solitons and of well localized initial data by the Novikov-Veselov (NV) equation at different levels of the 'energy' parameter E. We show that as |E| -> infinity, NV behaves, as expected, similarly to its formal limit, the Kadomtsev-Petviashvili equation. However at intermediate regimes, i.e. when |E| is not very large, more varied scenarios are possible, in particular, blow-ups are observed. The mechanism of the blow-up is studied.
Le processus de diffusion du football en Franche-Comté
2006
This paper seeks to demonstrate, from a geographical viewpoint, how football, a sport that was fairly undeveloped at the beginning of the 20th century, has become a major element in daily life. Taking the region of Franche-Comté (population: 1.1 million) as an example, the spatialisation of the diffusion cycle of the sport is shown (introduction into the territory, growth, then saturation). The territorial dimension of football is thus analysed.
Structural studies of acyl esters of entacapone
2001
Abstract The crystal structures of entacapone [(E)-2-cyano-N,N-diethyl-3-(3,4-dihydroxy-5-nitrophenyl)propenamide] and three of its acyl esters were solved. Entacapone, and its monopivaloate and diacetate derivatives, exist in the E-form while its dibenzoate derivative adopts the Z-form in the crystalline state. The ethyl substituents of the E-form are not freely rotating, as demonstrated by the broad signals in the 1H and 13C NMR spectra. The rotation barrier for the E-form was defined by the crystal structures, which show that free rotation of the ethyl substituents is blocked by the cyano-group.

El comte Arnau, la migració d’un mite
2016
Resum: En aquest article es presenta l’estudi de la figura del comte Arnau, heroi llegendari sorgit a les terres de la Catalunya Vella el drama del qual ha travessat els segles i ha estat difos per mitja d’una balada i uns textos llegendaris de caracter oral. El senyor poderos i malvat, sacrileg sense escrupols i amic del diable, apareix a la seva esposa despres de mort, sorgit de l’infern, com una anima en pena que recorre la terra muntat en un cavall de flames. La balada, en forma de dialeg entre la dama i l’espectre del comte, ens reconta la causa de la seva condemna: «per soldades mal pagades», perque no paga els jornals que havia promes als seus treballadors. Per mitja de la historia l…
El testament del marqués de Villatorcas i la disputa del compte de Cervelló per l'herència paterna : una altra conseqüència de l'exili austracista.
2007
Felipo Orts, Amparo - Amparo.Felipo@uv.es En el context de les conseqüències de l'exili austriacista vinculat a la Guerra de Successió, aquest article estudia els desencontres familiars que va haver de salvar don Juan Basilio de Castellví, exiliat a Viena, per a veure reconeguts els seus drets a la part de l'herència familiar que assegurava correspondreli, derivats, al seu torn, del conflicte personal que per a son pare, el marqués de Villatorcas, va haver de suposar la necessitat de disposar les seues últimes voluntats -en forma de poder públic- abans de la firma de la Pau de Viena de 1725.
