Cation Environment in BaCeO3-Based Protonic Conductors: a Computational Study

2009

Geometry calculations were performed on pure BaCeO(3) fragments and on Y- and In-doped derivatives. HF and DFT approaches were used to investigate monoclinic and orthorhombic structures. The computational methods, structural models, and electronic structure investigation protocols were tuned taking into consideration and balancing the consistency of the results against the computational cost. The calculated structures and energetics parameter, as well as the detailed orbital analysis performed on the corresponding BaCeO(3) derivatives allowed us to explain experimental findings and to develop a procedure to study the cationic octahedral environment of doped X:BaCeO(3) (X = Y, In) and undope…

Les sites fortifiés protohistoriques du Haut-Beaujolais : bilan de trois années de recherches entre Loire et Saône

2016

Dans le cadre du PCR dirigé par F. Delrieu, un programme de prospection des sites fortifiés de hauteur a été engagé entre 2013 et 2015 dans le Haut-Beaujolais, territoire auparavant méconnu dans ce domaine. Ces recherches ont permis la découverte de 19 sites inédits, portant à 22 le corpus local. Sur l’espace investis, de près de 1000 km², 344 sommets ont été vérifiés, selon une approche voulue systématique. Le corpus est essentiellement constitué d’enceintes complètes ou partielles, dont la superficie varie de quelques milliers de m² à près de 3 ha pour le site le plus étendu. Deux des sites inventoriés ont fait l’objet de sondages, permettant de documenter pour l’un d’eux une occupation d…

Short-term e-cigarette vapour exposure causes vascular oxidative stress and dysfunction: evidence for a close connection to brain damage and a key ro…

2019

Abstract Aims Electronic (e)-cigarettes have been marketed as a ‘healthy’ alternative to traditional combustible cigarettes and as an effective method of smoking cessation. There are, however, a paucity of data to support these claims. In fact, e-cigarettes are implicated in endothelial dysfunction and oxidative stress in the vasculature and the lungs. The mechanisms underlying these side effects remain unclear. Here, we investigated the effects of e-cigarette vapour on vascular function in smokers and experimental animals to determine the underlying mechanisms. Methods and results Acute e-cigarette smoking produced a marked impairment of endothelial function in chronic smokers determined b…

Tropes of Travel in Bernardine Evaristo’s Novels

2011

This paper is informed by an interpretative framework in which the theoretical paradigms of Cultural, Gender, (Post-)colonial and Tourism studies are interwoven. It is claimed that fostering a specific kind of literary and cultural tourism, centred on (post-)colonial authors’ works, might emerge as a political practice able to reshape the self-fashioning of Western European cultural heritage in non-essentialized terms. Consequently, this would also help promote cross-cultural exchanges. In this respect, Lara (1997), The Emperor’s Babe (2001) and Soul Tourists (2005), the first three novels by the London-born Anglo-Nigerian writer Bernardine Evaristo, appear to be extremely relevant literary…

Bernardine Evaristo’s The Emperor’s Babe: Re-Narrating Roman Britannia; De-Essentializing British National Identity

2014

The essay aims to demonstrate that, by representing the Black group as integral to British history, Bernardine Evaristo's The Emperor’s Babe imaginatively intervenes into the contemporary transmission of European history by unseating the conventional notion of racial purity on which the Western historical archive has been built. The novel thus questions hegemonic notions of Britishness and simultaneously re-inscribes them by offering new inclusive configurations of the British identity. Evaristo’s complex articulation of inter- and intra-gender power relations prevents the novel from developing the ethnic motif in simplistic celebratory terms and simultaneously enables the narrative to intr…

Bernardine Evaristo’s The Emperor’s Babe: De-essentialising Euro-Mediterranean History

2011

Informed by an interpretative framework where the theoretical paradigms of British Cultural studies and Black feminism inextricably interweave, the paper aims at illustrating a complex identity model of the Black British woman as delineated in Anglo-Nigerian writer Bernardine Evaristo’s The Emperor’s Babe (2001). Published at the turn of the 21st century, Evaristo’s second novel-in-verse revolves around the life-experience of a young black woman born of Sudanese parents in Roman London, Zuleika, who ends up having an intense relationship with the Roman Emperor Septimius Severus. In its highly orchestrated narrative fabric where prose and poetry conflate, this unconventional historical novel…

Automated pre-column derivatization of amines in biological samples with dansyl chloride and with or without post-column chemiluminescence formation …

1999

On-line automation of two different liquid chromatographic procedures, a pre-column derivatization system and a pre- and post-column system, in order to generate chemiluminescence is reported. Dansyl chloride (Dns-Cl) was used as a pre-column reagent to form fluorophores and bis(2,4,6-trichlorophenyl) oxalate (TCPO) and hydrogen peroxide (H2O2) as a post-column reagent to generate chemiluminescence. This procedure is based on the employment of a primary column packed with C18 material inserted in a multi-dimensional assembly for sample clean-up and derivatization with Dns-Cl. The dansyl derivatives formed are transferred and separated in a LiChrospher 100 RP18 analytical column (125 x 4 mm …
