Latin America and the Global Cold War
No full textLatin America and the Global Cold War analyzes more than a dozen of Latin America’s forgotten encounters with Africa, Asia, and the Communist world, and by placing the region in meaningful dialogue with the wider Global South, this volume produces the first truly global history of contemporary Latin America. It uncovers a multitude of overlapping and sometimes conflicting iterations of Third Worldist movements in Latin America, and offers insights for better understanding the region’s past, as well as its possible futures, challenging us to consider how the Global Cold War continues to inform Latin America’s ongoing political struggles.

Cellule staminali nell'ascidia coloniale Botryllus schlosseri: caratterizzazione di nicchie, fattori di staminalità e dinamiche di differenziamento.
No full textBotryllus schlosseri is a cosmopolitan colonial ascidian pertaining to tunicates, the sister group of vertebrates. It can regenerate entire organisms from a pool of circulating cells when all zooids are removed from a colony. Moreover, it possesses asexual reproduction, in which new individuals continuously develop, while old individuals are resorbed. The close relationship with vertebrates, the constant replacement of old individuals by newly formed zooid generations, together with the high regenerative abilities characterizing this species, make this organism a captivating model for the study of stemness that is the focus of my PhD project.
During my PhD, I submitted two book chapters. A first one concerns the methodologies used to study regeneration in colonial and solitary ascidians, since the end of the 19th century until nowadays (Methodological approaches for the study of regeneration in ascidians: an historical overview. Vanni V, Ballarin L, Gasparini F, Peronato A, Manni L (2022). Whole-Body Regeneration: Methods and Protocols. Methods in Molecular Biology, Springer). The long history of studies in ascidians highlights how these organisms are easy to maintain in laboratory conditions, manipulate and follow in vivo. Indeed, the methodologies to induce the regeneration processes have not changed so much, as they are simple, low cost, and effective. However, even if many molecular and cellular tools are still missing for studying these organisms, by applying modern techniques, it has been possible, in recent years, to uncover some features characterizing ascidian stem cells. This is the subject of the second book chapter (Current Knowledge on Stem Cells in Ascidians. Vanni V, Anselmi C, Ballarin L, Drago L, Gasparini F, Gordon T, Peronato A, Rosental B, Rosner A, Rinkevich B, Spagnuolo A, Manni L, Voskoboynik A (2022). Advances in aquatic invertebrate stem cell research, MDPI).
Moreover, I followed three different lines to better characterize stemness in B. schlosseri, which are included in different articles.
In a paper in collaboration with Prof. Carmela Gissi (Università di Bari, IT), currently under revision, we verified a possible common expression pattern between vertebrate embryonic stem cells and adult candidate stem cells of B. schlosseri. We carefully retrieved the orthologous in B. schlosseri Yamanaka Factors (Myc, Pou2, Pou3 and SoxB1), and studied, through in situ hybridization, the expression of these genes during all the phases of the asexual cycle of this colonial ascidian. Our results highlight a conserved expression pattern of myc, pou3 and soxB1 in undifferentiated, developing territories, consistently with the expression pattern observed in other chordate species. Moreover, the genes are expressed in small round cells (candidate stem cells) located in the stem cell niches identified until now in B. schlosseri, suggesting that they may play a role in stemness.
In another paper (in preparation), we characterized the stem cell niches identified until now in B. schlosseri, by 3D reconstruction and histology, showing for the first time their cell structure and anatomy. We then investigated the contribution of candidate stem cells to the development of primary and secondary buds, confirming their infiltration in previously hypothesized sites, but also demonstrating that they can contribute to the development of organs and tissues previously not individuated.
Finally, a last paper (in preparation in collaboration with Prof. Jordi Solana, Oxford Brookes University, UK), regards the single cell transcriptomics of B. schlosseri: we successfully produced an atlas of 37 clustered cell populations, validated through published datasets and expressing markers for specific tissues. This atlas will be the basis for future analysis on stemness and differentiation in this organism.
Altogether, with the results obtained during my PhD, we advanced the knowledge on stem cells of B. schlosseri.Botryllus schlosseri is a cosmopolitan colonial ascidian pertaining to tunicates, the sister group of vertebrates.

Fashion Fabulation: Serpica Naro at Milan Fashion Week 2005
No full textIlaria Vanni writes about the fictional fashion designer Serpica Naro, an anagram of the name for San Precario , the fictitious patron saint of precarious workers. Vanni describes the shenanigans got up to by Serpica Naro (in reality the activist group Chainworkers assisted by sundry precarious workers in the fashion industry), including having the designer admitted to Milan Fashion week, and then getting as much publicity as possible through the various stunts they engineered throughout the city.
Vanni brings academic research based in design activism to bear on the concept of fabulation. Drawing on the work of design theorist Daniela K. Rosner, she argues that critical fabulation is a speculative proposal for a better way to live (and work) in the present and the future: it involves ‘the imagination of fashion practices to come that might still be otherwise’. Serpica Naro’s intervention, then, is an alternate history of Milan fashion week achieved through activism and intervention rather than writing or other forms of polemic. In this sense, the group’s activities represent the future anterior tense of activism. As Vanni demonstrates, Serpica Naro’s uchronic temporality gave a voice to Milanese activists, showing how the actions of a fi ctional character can have real impact through collective action
A Study on the Symptomatology and Diagnostic Methodology of Vanni Pitham
No full textVanni Pitham a clinical entity was described by Sage Yugi in his wisdom. The study conducted has come out with excellent results validating the clinical features of Vanni Pitham elucidated in an ultra short poetic segment by Yugi. The study was aimed at evolving a set of exclusive Siddha diagnostic findings for Vanni Pitham with the observation and inference of various parameters like Naadi, Neikkuri and disease acquired season, it can be concluded that all of them point to the development or vitiation of humour leading to the disease Vanni Pitham. The patient reported with the symptoms of Vanni Pitham were subjected to the standard set of investigations, the results and findings of the investigations were suggestive of Vanni Pitham according to modern classification of disease. Manikkadai Nool and Nei kuri findings may help in the identifying of preponderance in a person to develop Vanni Pitham, hence it can be used as a screening measure to advise the preventive measures well in advance. Almost the patients who diagnosed as Vanni Pitham had significant study of colonoscopy evidence conforming to the correlation of disease with inflammatory bowel disease. From the analysis done between Vanni Pitham cases and control group, notable variations were observed in both Siddha and Modern parameters. Interestingly, it was found that the symptoms presented by the patients in the study were those of a constant subset of symptoms of inflammatory bowel disease explained in the present day classification. It correlated with all of the symptoms mentioned by Yugi muni under Vanni Pitham. Thus the author concludes by throwing lights on validation of symptomatology and exclusive Siddha diagnostic methodology for Vanni Pitham so that a physician can arrive at proper treatment procedures by rightly diagnosing the disease

Simulation of coalescence, break up and mass transfer in bubble columns by using the Conditional Quadrature Method of Moments in OpenFOAM
No full textThe evaluation of the mass transfer rates and the fluid-dynamics aspects of bubble columns are strongly affected by the intrinsic poly-dispersity of the gas phase, namely the different dispersed bubbles are usually distributed over a certain range of size and chemical composition values. In our previous work, gas-liquid systems were investigated by coupling Computational Fluid Dynamics with mono-variate population balance models (PBM) solved by using the quadrature method of moments (QMOM). Since mass transfer rates depend not only on bubble size, but also on bubble composition, the problem was subsequently extended to the solution of multi-variate PBM (Buffo et al. 2013). In this work, the conditional quadrature method of moments (CQMOM) is implemented in the open-source code OpenFOAM for describing bubble coalescence, breakage and mass transfer of a realistic partially aerated rectangular bubble column, experimentally investigated by Diaz et al.(2008). Eventually, the obtained results are here compared with the experimental data availabl
L'evoluzione delle articolazioni interne della Croce Rossa Italiana
No full textNell’esposizione del presente capitolo, dedicato all’evoluzione delle ar¬ticolazioni interne alla Croce Rossa nel periodo che va dai primi anni Ses¬santa del XIX secolo alle soglie della Prima Guerra Mondiale, si intrecciano due dimensioni fondamentali, quella del volontariato e quella della professione, in quanto queste due anime sono ben presenti nella Croce Rossa sin dalle sue origini, se si pensa da un lato che il primo comitato ita¬liano sorse in seno dall’Associazione medica italiana, e dall’altro che l’elemento di coinvolgimento di persone volontarie è sempre stato una co¬stante dell’Associazione, ben esemplificato in primis dall’elemento del socio. Il capitolo si svilupperà esaminando i vari soggetti principali che hanno fatto parte dell’Associazione, contribuendone alla sua creazione ed al suo sviluppo, concentrando in particolare l’attenzione sulle figure dei soci, trattandone in maniera trasversale la composizione interna, delle donne, de¬gli infermieri, dei medici, dei militari e del personale amministrativo. Spesso, inoltre, si faranno ampi riferimenti, come ad esempio nel caso par¬ticolare degli infermieri, alla situazione e ai dibattiti esistenti nella società, in quanto è ferma convinzione dell’esistenza di un rapporto osmotico in una dinamica di influenza circolare tra la società italiana e la Croce Rossa, dove per circolarità si intende «confinare, essendo uno dentro l’altro. Sostenersi a vicenda. Risultare l’uno figlio dell’altro
