Artista del porvenir [nel Dosier "Arrigo Boito"]
No full textBreve profilo biografico di Arrigo Boito, con particolare attenzione al suo legame con la Scapigliatura, al suo impegno socio-politico, alla sua produzione librettistica (anzitutto per Verdi) e alla relazione con Eleonora Duse.It's a short description of Arrigo Boito's life. It shows especially the connection between Scapigliatura and this author, his public dedication, his production of librettos (above all for Giuseppe Verdi) and his relationship with the famous actress Eleonora Duse
L'astrazione come atmosfera: appunti su Arrigo Parnisari
No full textIl saggio ripercorre la carriera di Arrigo Parnisari, pittore ossolano attivo soprattutto a Milano e a Firenze, dove ebbe stretti contatti con gli artisti di "Arte d'oggi", e dove seppe inserirsi con voce originale nel dibattito sull'astrazione e sul suo potenziale politico
Mittag-Leffler Functions and their Applications in Network Science
No full textWe describe a complete theory for walk-based centrality indices in complex networks defined in terms of Mittag-Leffler functions. This overarching theory includes as special cases wellknown centrality measures like subgraph centrality and Katz centrality. The indices we introduce are parametrized by two numbers; by letting these vary, we show that Mittag-Leffler centralities interpolate between degree and eigenvector centrality, as well as between resolvent-based and exponential-based indices. We further discuss modelling and computational issues, and provide guidelines on parameter selection. The theory is then extended to the case of networks that evolve over time. Numerical experiments on synthetic and real-world networks are provided
Hybrid supramolecular gels of Fmoc-F/halloysite nanotubes: systems for sustained release of camptothecin
No full textSupramolecular gel hybrids obtained by self-assembly of Fmoc-L-phenylalanine (Fmoc-F) in the presence of functionalized halloysite nanotubes (f-HNT) were obtained in biocompatible solvents and employed as carriers for the delivery of camptothecin (CPT) molecules. The synthesis of the new f-HNT material as well as its characterization are described. The properties of the hybrid hydrogels and organogels were analyzed by several techniques. The presence of small amounts of f-HNT allows good dispersion of the tubes and the subsequent formation of homogeneous gels. The experimental results show that f-HNT functions only as an additive in the hybrid gels and does not demonstrate gelator behavior. The in vitro kinetic release from both f-HNT/CPT and Fmoc-F/f-HNT/CPT was studied in media that imitates physiological conditions, and the factors controlling the release process were determined and discussed. Furthermore, the antiproliferative in vitro activities of the gels were evaluated towards human cervical cancer HeLa cells. A comparison of data collected in both systems shows the synergistic action of f-HNT and the gel matrix in controlling the release of CPT in the media and maintaining the drug in its active form. Finally, a comparison with pristine HNT is also reported. This study suggests a suitable strategy to obtain two-component gel hybrids based on nanocarriers with controlled drug carrier capacity for biomedical applications
Un incartamento dalla Beozia. Sulle "Resultanze in merito alla Vita e al Carattere di Gino Bianchi" di Piero Jahier
No full textNel romanzo di Piero Jahier "Resultanze in merito alla Vita e al Carattere di Gino Bianchi" compare un nuovo tipo di personaggio, nello stesso tempo idiota e santo, che proprio nella letteratura di quegli anni trova le sue caratterizzazioni più importanti (dal Bartleby melvilliano ad Akaki Akakievic ai tanti 'impiegati della vita' della letteratura decadente). Cosa ne sarà di lui, come si trasformerà nel pieno della crisi che attraverserà il Novecento
Exchange and Production Equations: Understanding a Debate between Harrod and Sraffa
No full textHarrod’s claim, that the relative prices that solve Sraffa’s “no-surplus” equations reflect the ratios of the amounts exchanged, deserves more than the scanty tribute paid by the author of Production of Commodities by Means of Commodities. Not only, in fact, does this claim hold true in the simple sense referring to direct, bilateral exchange when there are two commodities (and, in special cases, when there are more than two), but it holds true generally, in the more elaborate sense referring to amounts directly and indirectly exchanged by pairs of industries
