    We performed the calculation of the scattering length for the elastic collision between the rubidium and cesium atoms. For this we applied a variational procedure based on the R-matrix theory for unbound states employing the finite element method (FEM) for expansion of the wave-function in terms of a finite set of local basis functions. The FEM presents as advantages the possibility of the development of a efficient matrix inversion algorithm which significantly reduces the computation time to calculate the R matrix. We also tested a potential energy curve with spectroscopic accuracy obtained before from a direct adjustment procedure of experimental data of the X1Σ+X^{1}\Sigma^{+} state based on genetic algorithm. The quality of our result was evaluated by comparing them with several ones previously published at literature.Comment: 15 pages, 6 tables and 2 figure

    Existe un creciente interés científico y tecnológico en el estudio de geles de gelatina debido a sus múltiples aplicaciones en la industria de alimentos y en biomedicina. Los geles de gelatina de pescado se utilizan menos que los de mamíferos, debido a su baja resistencia mecánica. La gelatina de pescado es un recurso disponible como desecho de la industria pesquera marplatense.Área: Ingeniería, Arquitectura y Tecnología

    ‘Misi me per l’alto mare aperto’:Personality and Impersonality in Virginia Woolf’s Reading of Dante’s Allegorical Language

    Although Dante’s influence on modernism has been widely explored and examined from different points of view, the aspects of Virginia Woolf’s relationship with the Florentine author have not yet been extensively considered. Woolf’s use of Dante is certainly less evident and ponderous than that of authors such as T.S. Eliot and James Joyce; nonetheless, this connection should not be disregarded, since Woolf’s reading of Dante and her meditations on his work are inextricably fused with her creative process. As I will show in this essay, Woolf’s appreciation of Dante is closely connected to major features of her narrative experimentation, ranging from her conception of the structure and design of the literary work to her reflections concerning the meaning and function of literary language. Woolf read Dante, and in particular the Commedia, throughout her life, presumably beginning with an English translation and later, when she had acquired a certain command of Italian, shifting to the original text. In addition to the annotations in her reading notebooks, Woolf’s considerations on her reading of Dante permeate her diary, often mingling with her reflections about her own writing. It is this osmotic penetration of Dante’s work into Woolf’s creative process which I intend to explore

    Virginia Woolf’s “Imageographie”: On New Paths in the Modernist Text-Image Interconnection

    The complexity of the relationship between Modernism and the visual arts involves consideration of the key theoretical crux of how and to what extent images reproduce reality. The cinema in particular has exerted a strong influence on Modernist writers as the novelty of the medium, and the new possibilities it offered, could not but arise the interest of writers that were at work with new, experimental modalities of writing. Yet in Modernist writers, as it happens in major theoretical reflections on the ʻrepresentationalʼ arts, the exploration of the relationship between images and words was a syncretic one, activating a dynamic interchange between words and pictorial, photographic and cinematic images (and narration). The article starts from these premises to consider a recent work in the field, Adèle Cassigneul’s Voir, observer, penser. Virginia Woolf et la photo-cinématographie (2018), which fills the gap of the less explored relationship between Modernism and photography while also proposing new aesthetic and poetic interpretative categories, such as Woolf’s photo-cinématographie and imageographie
