Interfacial mass transfer and chemical reaction in non-ideal multicomponent systems
No full textThe work investigates the role of non-ideality in interfacial multicomponent mass transfer with chemical reaction. These effects are produced by two different mechanisms. First non-ideal thermo-dynamics must be considered for the mixture, since it may affect both the diffusion rate (the true driving force for diffusion being the chemical potential gradient) and the reaction rate. On the other hand, the diffusion coefficients may vary with composition, due to the intrinsic kinetics of diffusion. These phenomena have been investigated for two limiting cases of fast reactions, that is, pseudo first order and instantaneous reaction. Diffusion rate was modelled by means of the generalized Maxwell-Stefan equation and the reaction was supposed bimolecular. The composition dependence of the diffusion coefficients plays a significant role only when the Maxwell-Stefan diffusivities at infinite dilution differ considerably from each other (four or five times), thus excluding most systems. Relevant actions caused by non-ideal thermodynamics have been detected only in highly non-ideal systems. Therefore, the expressions developed for ideal systems can often be extended to non-ideal one

Fantastic Architecture and the Building of Europe in Valerio Evangelisti's Eymerich Fiction
No full textConcomitant with the horizontal expansion of EU territory through physical and political enlargement is a genealogy narrative, which emphasizes the ostensible roots of Europeanness in classical antiquity and Christianity. In the face of this sanitized genealogy, which lies at the heart of the European constitutional project, a range of alternative and more inclusive narratives circulate in contemporary European popular fiction. This paper focuses on a series of fantasy novels by the Italian author Valerio Evangelisti, featuring Inquisitor Eymerich as hero-investigator. In his highly popular novels, Evangelisti seeks to uncover layers of shared historical memory untainted with post-Enlightenment rhetoric.
The central architectural tropes of Evangelisti’s imaginary world are those of a castle and a convent, epitomizing the temporal and sacral power in European history. Each isolated from its outside environment and built on layer upon layer of subterranean chambers and corridors, the castle and the convent conceal a past quite different from the one championed in the official European genealogy. Memories of pagan worship and Islamic or Judaic learning – banished from the official rhetoric – continue to thrive, dark and threatening, in the subterranean strata of Evangelisti’s European edifice. Evangelisti thus provides an incisive critique of the official European story of origin, which threatens to suppress any alternative visions of European history or unorthodox avenues for European identity formation

Hermann Kant. Ein bio- bibliografisches Profil
No full textThe proximity to the power apparatus has cast dark shadows on the literary work of Hermann Kant, who is regarded as one of the most read authors of the GDR. Valerio Furneri embeds Kant's life and work in the all-German context of the 20th century and reinterprets his classics such as Die Aula or Der Aufenthalt. The author does not pursue the claim to rehabilitate the GDR, nor to trivialise Kant's role in it. Instead, the attempt is made to look at Kant's entire work from a temporal distance and to re-evaluate it. Through his works, Kant was able to accompany and depict not only the German-German history, but also European history.Die Nähe zum Machtapparat hat dunkle Schatten auf das literarische Werk von Hermann Kant, der als meistgelesener Schriftsteller der DDR gilt, geworfen. Valerio Furneri bettet Kants Leben und Werk in den gesamtdeutschen Kontext des 20. Jahrhunderts ein und interpretiert vor diesem Hintergrund Klassiker wie Die Aula oder Der Aufenthalt neu. Der Autor verfolgt dabei weder den Anspruch, die DDR zu rehabilitieren, noch Kants Rolle darin kleinzureden. Stattdessen wird der Versuch unternommen, Kants Gesamtwerk aus zeitlicher Distanz zu betrachten und neu zu bewerten. Durch seine Werke gelang es Kant nämlich nicht nur die deutsch-deutsche, sondern auch die europäische Geschichte zu begleiten und abzubilden
