Internal jugular vein fenestration: a rare but possible event. A case report and review of the literature
Get PDFWhile fenestration and duplication are relatively common in the arteries, they are extremely rare in the venous compartment: internal jugular vein fenestration has been reported occurring in 0.4% of unilateral neck dissections. Familiarity with these morphological anomalies is important for the radiologist and for the surgeon to prevent neurovascular injury, especially in neck surgery and interventional catheterization. We present the case of a patient harboring a fenestration of the left internal jugular vein, diagnosed by magnetic resonance angiography, and a systematic review of the literature. To our knowledge, from 1985 until 2016 only 36 patients (including the present) were diagnosed as having an internal jugular vein morphological anomaly. Out of 36 patients, only 11 (30,5%) were diagnosed using radiological imaging; the high rate of intra-operative diagnoses (22/36, 62,5%) is likely related to the limited use of diagnostic imaging or to misdiagnosis/misinterpretation of a relatively unknown and rare morphological anomaly. A contrast enhanced computed tomography or magnetic resonance angiography should be considered in case of vascular procedures in a patient with known internal jugular vein anomaly
About French Vernacular Traditions: Medieval Roots of Modern Theatre Practices
Get PDFThe article gives an overview of the writing processes of theatre performances in medieval France. At the crossroads of all processes is the original (the Book, le Livre, les originaux) containing the full text, and from which all kind of copies were produced for different reading practices – entertainment, meditation, devotion, teaching, learning – identified by specific content, layout and material features. With the case study of Maistre Pierre Pathelin, a late fifteenth-century comedy, is shown how the text varies in the performance process and extemporizing practices of professional players, and finally sediments in its written circulation. Detail of the same process can be closely observed with the Mystère des Trois Doms, a great urban play of the early sixteenth century for which, exceptionally, both the Book and an account register of a unique performance have come to us. We conclude that, in the medieval history of theatre performance in France, the author is as much corporate as individual, and that extemporizing practices of professional players, from the thirteenth to the fifteenth century may well be a key in understanding the origins of the Italian commedia dell’arte which is generally presented as the beginning of modern professional theatre practices.
Effects of static and dynamic stretching on upper limb explosive, isometric and endurance strength, in male volleyball players
Get PDFThe purpose of this study was to investigate the acute effects of both static and dynamic stretching on upper limb strength and to assess whether a cross-over inhibitory effect occurred during the time in which this effect may appear. Eighteen male volleyball players (aged 21.50, standard deviation 3.12 years) underwent the experimental protocol organized in in two sessions, one of static and the other of dynamic stretching for upper body muscles. Participants performed three specific strength tests: Ball Throwing, Maximum Voluntary Isometric Contraction, and Push-Up, to assess explosive, isometric and endurance strength respectively, at baseline (T0) and 10, 20 and 60 minutes after the static stretching and dynamic stretching sessions. The Ball Throwing results showed significant differences between the two stretching protocols (F1,14 = 4.967; p = 0.043; ηp2 = 0.262), among the 5 time measures (F4,58 = 7.476; p < 0.001; ηp2 = 0.348), and for the interaction Protocol × Time (F4,58 = 8.258; p < 0.001; ηp2 = 0.371). Maximum Voluntary Isometric Ccontraction scores showed significant differences among the time measures (F4,58 = 4.015; p = 0.006; ηp2 = 0.223) and for the interaction Session × Time (F4,58 = 2.625; p = 0.044; ηp2 = 0.158). At the Push-Up test significant differences were found only among the time measures (F4,58 = 5.634; p = 0.001; ηp2 = 0.287). Static stretching may adversely affect upper limb endurance strength, whereas no changes in isometric and explosive strength were found. Dynamic stretching did not have a detrimental effect on upper limb endurance strength, whereas it may improve isometric and explosive strength
Eating an Onion. Notes on Marina Abramović
Get PDFThe Onion is a 1995 video performance by Marina Abramović. The essay aims at analyzing some central themes of the artist’s path, taking this work as reference text. First of all, by including the artist in the process of dissolution of beauty marking the art of the Twentieth century and regarding performance art as one of the outcomes of this process inaugurated by the avant-gardes. Secondly, by showing the link between the political dimension (in this particular case, the war in Yugoslavia in the 1990s) and an existential reflection focused on the role of the artist and the woman in the contemporary world
Decolonizing the Irish: The International Resistance and Entrenchment of the Global Irish Diaspora
Get PDFNarratives of Irish decolonization often take up local (rather than global) arguments focused on the liberation of Ireland, instead of looking to the participation of Irish people in decolonization efforts internationally. This paper argues that the Irish diaspora, whose population has extended into all corners of the Earth, has a key role to play in decolonization not simply because of the history of anti-colonialism in Ireland and its role as a test site for British colonialism, but specifically because of the need to extend sentiments about national liberation to the nations whose oppression the diaspora has become entrenched in. Through examining on historical examples of Irish roles in the colonization of Canada, the United States, and Australia, this paper explores some of the ways that the desire to contribute to the liberation of Ireland within the Irish diaspora has often become linked to participation in colonization. In so doing, it argues that the Irish nation cannot become decolonized by liberating its own land alone; it must become a force for anti-colonialism by rejecting participation in colonial occupation wherever the Irish find themselves. Drawing attention to opportunities for advancing allieships between the diaspora and other nations struggling against colonialism, the author puts forth a call to action for decolonizing the Irish
Up-one: problems issuing from upward extensions of 1950-1900 residential buildings
Get PDFThough presenting typological and construction-related features different from other European countries, Italian residential buildings as a whole fail to meet the performances required by the European Union before the 2050 deadline. Among the hypotheses meant to upgrade residential buildings, adding floors is regarded as capable of meeting the demand for new lodgings without any further soil consumption as well as of being the driving force leading to the overall upgrading of the building. The research has been aimed at focusing on the problems arising from upward extensions within the Italian seismic context, by means of digital environment surveys, defining intervention guidelines that can be applied to adding floors to 1950-2000 buildings
Antonio Ròiti
Get PDFUn recente articolo apparso su questa rivista e dedicato al progetto di un “Istituto di Misure Elettriche” ad Arcetri, là dove poi nascerà l’Istituto di Fisica, cita il Professor Antonio Ròiti; uno studioso poco conosciuto a causa della propria riservatezza ma non di secondo piano nel panorama italiano del Risorgimento. In questo contributo se ne ripercorrono brevemente la vita e le opere.A recent article published in this magazine and dedicated to the project of an “Institute of Electrical Measurements” in Arcetri, where the Institute of Physics was later to be founded, mentions Professor Antonio Ròiti; a little known scholar due to the fact that he was extremely reserved but not because he was of secondary importance in the Italian panorama of the Risorgimento. In this contribution, we briefly retrace his life and works
La caccia al fosforo interstellare, l’elemento pre-biotico dimenticato
Get PDFIl fosforo è un elemento cruciale per lo sviluppo della vita come la conosciamo, ma a causa della sua bassa abbondanza cosmica, fino a pochi anni fa la sua chimica interstellare era quasi del tutto sconosciuta. Dal 2016, il gruppo di Formazione Stellare di Arcetri ha contribuito in modo fondamentale alla comprensione di alcuni processi astrochimici che coinvolgono questo elemento in regioni della Galassia in cui si formano nuove stelle, aprendo la strada a un numero crescente di studi su questo elemento pre-biotico finora “dimenticato”.Phosphorus is a crucial element for the development of life as we know it, but because of its low cosmic abundance, until recently its interstellar chemistry was almost totally unknown. Since 2016, the star formation group at Arcetri has made a fundamental contribution to our understanding of the astrochemical processes that involve this element in the star-forming regions of the Galaxy, paving the way for a growing number of studies on this pre-biotic element that had been “forgotten” up to now
