Uso scientifico o professionale di simulazioni numeriche di diversa complessita' di fenomeni termofluidodinamici
No full textIn un precedente lavoro Dumas e Mazzacane (1993) hanno mostrato che l'utilizzo di software grafico tridimensionale, per l'impostazione di un problema di termofluidodinamica e per la restituzione dei risultati, rende la soluzione proponibile a fini progettuali grazie al ridotto impegno sia finanziario che temporale. In quel caso il confronto della soluzione teorica del comportamento di una lama d'aria con misure di tipo industriale mostrava una discrepanza nella peggiore delle situazioni inferiore al 15%. In questo lavoro analizzando lo stesso problema viene affrontato il confronto fra la soluzione numerica di una procedura che per tempi, costi e livello di approfondimento dei suoi fondamenti teorici e` ottenibile da un progettista, ed una piu` accurata che necessita pero` di risorse di calcolo oggi allo stesso non facilmente accessibili

Pietro Martire d'Anghiera, De Orbe Novo Decades, voll.1-2
No full textThis is the critical edition with parallel translation of the Decades De Orbe Novo, books I-VIII by Peter Martyr of Angleria, an Italian humanist who, during his life at the court of the Ferdinand and Isabella, catholic monarchs in Spain, was a witness of events bound to change the world and the course of history. In this work a thirty-four years' history of geographical discoveries and conquests is described in epistolary style, from Christopher Columbus's landing in the ''Indies'', up to the exploration of the Caribbean islands and Venezuela, the conquest of Mexico and the first American settlements.
Christopher Columbus, the Pinzons, supporters and participants in the Colombian project, the Vespuccis, together with Cabot, Cortés and Oviedo are the most famous characters of Peter Martyr; their reports to the Council of the Indies, the charts and the pilots' books are the sources allowing Peter Martyr and - later- his readers to become "desk travelers".
The typical ciceronian Latin is made a current language thanks to the use of popular expressions, proverbs of the time and exoticisms taken and adapted from other languages, sometimes even at the expense of the formal elegance,
The text, distributed in books, chapters and paragraphs has been reconstructed by collating the oldest editions, since neither an autograph nor a manuscript of the Decades de Orbe Novo has been found so far.
Spelling criteria have been thoroughly kept: they respect the spelling of the oldest editions (1516 and 1530) printed in Spain, that is to say in the cultural environment where the Author himself
lived. However, graphic fluctuations, even if common in umanistic texts, have been standardized as they would have caused spelling disorder, while some neologisms, typical of the language heritage acquired by the Author in Spain, have been preserved in the graphic form closer to Spanish The critical apparatus indicates the differences between the editions collated, which are the following:
H = ed. Hispali 1511 (Decas I)
C1 = ed. Compluti 1516 (Decades I-III)
Ba = ed. Basileae 1521 (Decas IV)
C2 = ed. Compluti 1530 (Decades I-VIII) =
G = ed. anastatica Graz-Akademische Druck-u.Verlagsanstalt 1966
Pa = ed. Parisiis 1532 (Decas IV)
B = ed. Basileae 1533 (Decades I-III; Decas IV)
P = ed. Parisiis 1587 (Decades I- VIII)
E = consensus editionum Ba Pa B (Decas IV).
The parallel translation has been carried out so as to reflect the immediateness and expressiveness in the Author's style. Whenever any difficulties have arisen in the attempt to render terms of some classical and medieval texts in Italian, in general, when possible, the Latin pattern has been avoided, giving preference, instead, to technical terms considered to be more faithful to the social, political, legal and military situations of the time, according also to the Latin-Spanish dictionary of the humanist, Elio Antonio de Nebrija.
As to the New World's geographical names, they are been translated into Spanish, since, on the one hand, Spanish (or Portuguese) is the language used by the discoverers and, on the other, such places are now known with Spanish names.
The edition is completed by accompanying notes and three indexes, the former, of different kinds, are marked by an asterisk over the number indicating the paragraph in the translation and appear in two appendixes to the Decades I- IV and V- VIIII respectively. They help provide both an explanation and a first hint for further investigation. The latter refer to native terms, proper nouns and placenames.
The work is composed as follows:
- Introduction, edition criteria, collating the edition of Seville (1511) for the first Decade, the Basel edition of 1512, in Paris in 1532 and Basel in 1533 for the fourth Decade with edition, translation and notes of the preliminary texts by Rosanna Mazzacane;
- Edition, translation and notes of the Decades I-IV by Elisa Magioncalda;
- Edition, translation and notes of the Decade V-VIII by Rosanna Mazzacane;
- Bibliography and Index of indigenous terms, proper names and names of places by Rosanna Mazzacane and Elisa Magioncalda
Analisi di fenomeni di ventilazione per ambienti a diversa geometria mediante l'utilizzo di tecniche numeriche
No full textNel presente lavoro, in riferimento ad una particolare tecnologia di ventilazione, nota comunemente con il nome di "lama d'aria", viene mostrato che le possibilita' di utilizzo di software tridimensionale nell'impostazione del problema e nella restituzione dei risultati impongono la rivisitazione delle metodologie di progettazione. Infatti questi nuovi strumenti di indagine consentono l'analisi di fenomeni particolari quali effetti di bordo, transitori, processi di diffusione termica e/o di materia, che fino ad oggi era possibile effettuare solo a fini teorici, risultando difficilmente proponibile per scopi progettuali per l'impegno ed i costi corrispondenti

Abstract: INTRODUCTION: End-stage renal disease patients on hemodialysis (HD) often present osteoarticular and musculoskeletal complications related both to chronic renal disease as well as to chronic dialysis. The aim of the present study was to assess the degree of upper-limb disability, and its determinants, in a group of patients on chronic HD to determine functional capacity and the need for rehabilitative treatment.
MATERIALS AND METHODS: We studied 97 HD patients (46 male, 51 female) with a mean age of 64.4 years, and 51 healthy controls. The Disabilities of the Arm, Shoulder, and Hand (DASH) Outcome Measure was used to clinically assess degree of disability as well as finger function and movement.
RESULTS: For study purposes, patients were divided into 3 groups according to the duration of dialysis: 10 years. The median DASH score was 9.5 (interquartile range [IQR]: 3.4-24.1) in the entire population. However, it differed significantly in the 3 dialysis groups with scores of 5.2 (IQR: 2.6-18.1), 14.7 (3.4-23.7), and 37.5 (9.5-73.3) in the 10 year groups, respectively (p < .001). Additionally, disability correlated with shoulder and hand pain and with finger stiffness. Moreover, patients on dialysis for more than 10 years were affected by pain involving several upper limb joints. All patients who worked had a DASH score lower than 20. The median DASH score was 2.6 (IQR: 0.9-5.2) in the control group.
CONCLUSION: Duration of dialysis is associated with progressive disability. Thus, early rehabilitation programs are recommended in patients who are expected to undergo long-term dialysi
