Improving sustainability of sediment management in Alpine reservoirs: control of sediment flushing operations to mitigate downstream environmental impacts.
This thesis focuses on the desiltation of Alpine reservoirs in order to sustain their long-term utilization and restore the functioning of the bottom outlets, minimizing at the same time downstream environmental impacts of sediment removal operations. Different case studies of controlled sediment flushing operations (CSFs) are analysed adopting a multidisciplinary approach. In particular, sediment transport and downstream riverbed alteration, ecological impacts on benthic macroinvertebrates and fish, and performance indicators were investigated. Moreover, the experimental dataset acquired before, during, and after a sediment removal operation was used to carry out and calibrate a one-dimensional sediment transport model of the monitored event. The duration of the CSFs and the average suspended sediment concentration in the outflowing water were constrained, with the specific environmental objective of limiting the downstream fish mortality as predicted by a simple dose/response model. The biomonitoring indicated that this model allowed for a first approximation estimate of the impacts on trout. On the other hand, similar scenarios of sediment removal in terms of duration and average SSC can be identified with analogous predicted impacts on fish but non-negligible differences in flushing efficiency. Therefore, site-specific investigation of environmental impacts may be the key aspect for upgrading the trade-off between economic and environmental needs in planning further operations in the same area

Yona Hanhart-Marmor, Des pouvoirs de l’ekphrasis. L’objet auratique dans l’œuvre de Claude Simon
Fin dall’apparizione del Nouveau Roman, l’oggetto e lo sguardo sono emersi come i due elementi nei quali si condensa la novità narrativa introdotta dal gruppo. È a una rilettura di questi due punti cardine che approda la monografia su Simon, entrambi centrali nella figura dell’ecfrasi. L’autrice supera la vasta bibliografia che ha trattato dei rapporti fra la scrittura di Simon e la pittura puntando la sua attenzione sulla consapevolezza acuta della frattura che separa queste due arti. A ques..
R. Causse, Conversations avec Nathalie Sarraute
Nel 1985 Rolande Causse, autrice di libri per ragazzi, conosce Nathalie Sarraute. Nonostante la grande differenza d’età – la prima ha 46 anni, la seconda 85 – iniziano a incontrarsi regolarmente fino al 1999, anno della morte della Nouvelle Romancière. A distanza di altri diciassette anni dalla fine di questa lunga amicizia, Rolande Causse sente il bisogno di non disperdere il piccolo tesoro emotivo creato da quegli incontri, materializzandolo in diciotto conversazioni suddivise per temi: dal..
How the Italian scene appropriated L’Homme semence: The adaptation strategies of a so-called manuscript
Sonia Bergamasco’s adaptation of L’Homme semence by Violette Ailhaud makes use of a single actor reciting, even if, in a staging that emphasizes plurimediality, it is not possible to define L'uomo seme as a real monologue.
The analysis will take into account first the structure of the story, the strains that the plot imposes on the fabula and the effects it has on its global meaning; the linguistic marks that oppose the choral speech to the individual discourse, and the mentions referring to a culture anchored in a territory in a precise moment of history, which are superimposed on a speech that touches on the universal.

Présence de Samuel Beckett, édité par Sjef Houppermans, Actes du Colloque de Cerisy-la-Salle
À la veille du centenaire de la naissance de Beckett les plus accrédités spécialistes de son œuvre se sont réunis dans le château de Cerisy pour faire le point sur une œuvre complexe qui n’a jamais fini de solliciter la critique. L’ambition était vaste, digne des meilleures décades de Cerisy, dans sa volonté d’investiguer sa présence dans l’histoire, dans la philosophie, dans la recherche esthétique; d’analyser une œuvre qui se situe à la convergence de deux langues, et où l’émergence du corp..
Relire Perec, Actes du Colloque de Cerisy, sous la direction de Christelle Reggiani
«Je n’écris que pour être relu»: la phrase célèbre de Gide, qui console bon nombre d’écrivains s’estimant mal lus par leurs contemporains, n’aurait peut-être jamais eu l’adhésion de Perec, qui se souciait moins de sa postérité que de la jubilation présente de l’acte d’écriture. Mais la richesse même de l’œuvre de cet auteur, désormais grand classique, comme l’affirme dans la présentation Christelle Reggiani, ne cesse de susciter de nouvelles approches critiques: les actes du Colloque de Ceris..
Nicolas Di Méo, Le Cosmopolitisme dans la littérature française
La prima metà del secolo scorso è stata oggetto di approfonditi studi sull’articolazione fra letteratura e ideologie, ma mancava ancora un quadro d’insieme su un’idea che percorre in modo trasversale il campo letterario visto da una prospettiva storico-ideologica. Sulla complessità del cosmopolitismo analizzato senza ignorarne le sfumature Di Méo non manca di insistere, mostrando evoluzioni e differenze non solo fra un periodo e l’altro, ma spesso all’interno dell’opera di ogni singolo autore..
