Impact de l'art de la guerre napoléonien dans la seconde moitié du XIXe siècle

Le 18 juin 1815, Napoléon fut renversé à Waterloo, mais son art de la guerre survécut. Il s'agit de cet art militaire qu'il avait révolutionné et dont d'autres firent de nombreuses applications longtemps après sa disparition. S'inspirant des méthodes des théoriciens du XVIIIe siècle, il avait privilégié la stratégie d'anéantissement dans la conduite d'opérations militaires et se classait ainsi dans la catégorie des stratèges recherchant avant tout la bataille d��cisive en vue de d��truire les forces ennemies. À la lumière des tactiques et stratégies que Bonaparte utilisa dans ses plus célèbres campagnes, cette thèse tentera de d��gager les méthodes napoléoniennes qui furent le plus souvent utilisées au cours de la seconde moitié du XIXe siècle. Les conflits étudiés durant cette période seront la guerre de Crimée (1853-1856), la campagne d'Italie (1859), la guerre de Sécession américaine (1861-1865), la guerre austro-prussienne (1866) et la guerre franco-prussienne (1870-1871). Cette recherche tiendra compte non seulement de l'influence des progrès de l'armement et des moyens de transport et de communication sur l'art de la guerre en général, mais aussi du contexte économique, financier, politique et militaire des États bélligérants de cette époque. Parmi les nombreux exégètes de Bonaparte du XIXe siècle, deux théoriciens militaires en particulier, Clausewitz et Jomini, se distinguèrent dans l'interprétation savante de la guerre napoléonienne. Tout en analysant l'impact des méthodes de l'Empereur dans les guerres selectionnées, nous allons d��terminer dans quelle mesure la vision jominienne des campagnes de Bonaparte divergeait de celle de Clausewitz en ce qui concerne les conflits traités. Nous aborderons ensuite l'influence napoléonienne sur l'administration, l'organisation et les marches des armées impliquées dans les guerres en question et nous porterons une attention particulière à l'impact du système militaire de Bonaparte sur certains aspects du d��roulement même des combats. Nous terminerons cette étude par un bref aperçu sur les enseignements que les militaires au XIXe siècle purent d��gager des campagnes napoléoniennes pour la conduite des guerres de l'avenir.

Records d'un final d'estiu a Olot: Rusiñol al "país del paisatge"

Estudi de Santiago Rusiñol en els seus orígens com a pintor,i descripció de la seva estada a Olot a l'estiu i principis de tardor de 1988, en què va pintar una trentena d'olis, què el mateix any va exposar a la Sala Parés com a part de la seva primera exposició individual. És llavors quan ell decideix dedicar-se a la pintura. El pintor es referia a Olot com el "país del paisatge"

Reactions of Nb2 and Nb3 with CO, D2, N2, and O2 : reconciling experimental kinetics with density functional theory-calculated reaction profiles

 Calculated energy profiles for the reactions of neutral Nb₂ and Nb₃ metal clusters with CO, D<sub>2, N₂, and O₂ are presented. In each reaction path, both a physisorption energy minimum, where the reactant remains intact, and a chemisorption energy minimum, where the reactant has dissociated, are calculated and linked by saddle points. We calculate branching ratios for the forward (dissociative) and reverse reactions which we compare with the experimental kinetic data. It is found that a combination of average thermal energies and barrier heights leads to wide variation in branching ratios which compares favourably to previously determined experimental reaction rates.
