SURGICAL TREATMENT OF SACROCOCCYGEAL PILONIDAL SINUS WITH THE LIMBERG FLAP: REVIEW OF 81 CASES

2016

Pilonidal sinus disease is a complex condition that causes both discomfort and embarassment to suffers. Direct cost through absence from work is high. Controversy still exists regarding the best surgical technique for its treatment in terms of minimizing disease recurrence and patient discomfort. Thus, we conducted this study to evaluate the results of rhomboid excision and Limberg flap reconstruction in the surgical treatment of pilonidal sinus disease. This prospective study included 81 patients who had pilonidal sinus and were treated by the rhomboid excision and Limberg flap. The mean follow-up was 18 months and all patients were satisfied with the procedure. There were lower complicati…

I siti web delle catene alberghiere italiane. Un'applicazione della teoria

2002

Per conoscere in che modo alcuni operatori del settore turistico comunicano la loro immagine al mercato mondiale attraverso l’utilizzo di reti telematiche, ho pensato di condurre un’analisi dei siti web delle catene alberghiere italiane. Obiettivo principale del lavoro è la conoscenza del modo in cui il turismo ed i servizi offerti dagli alberghi, raggruppati in catene alberghiere, vengono comunicati in forma associativa sul web. Per raggiungere questo scopo, è necessario misurare la capacità comunicativa dei siti esaminati partendo dalla considerazione che il web va considerato come un prodotto di relazioni sociali. Per procedere a quest’analisi, utilizzerò la teoria multidimensionale dell…

The classical two-dimensional Heisenberg model revisited: An $SU(2)$-symmetric tensor network study

2021

The classical Heisenberg model in two spatial dimensions constitutes one of the most paradigmatic spin models, taking an important role in statistical and condensed matter physics to understand magnetism. Still, despite its paradigmatic character and the widely accepted ban of a (continuous) spontaneous symmetry breaking, controversies remain whether the model exhibits a phase transition at finite temperature. Importantly, the model can be interpreted as a lattice discretization of the $O(3)$ non-linear sigma model in $1+1$ dimensions, one of the simplest quantum field theories encompassing crucial features of celebrated higher-dimensional ones (like quantum chromodynamics in $3+1$ dimensio…

Performance Analysis of Cooperative V2V and V2I Communications Under Correlated Fading

2019

Cooperative vehicular networks will play a vital role in the coming years to implement various intelligent transportation-related applications. Both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be needed to reliably disseminate information in a vehicular network. In this regard, a roadside unit (RSU) equipped with multiple antennas can improve the network capacity. While the traditional approaches assume antennas to experience independent fading, we consider a more practical uplink scenario where antennas at the RSU experience correlated fading. In particular, we evaluate the packet error probability for two renowned antenna correlation models, i.e., cons…

Large-scale effects of migration and conflict in pre-agricultural groups: Insights from a dynamic model.

2016

The debate on the causes of conflict in human societies has deep roots. In particular, the extent of conflict in hunter-gatherer groups remains unclear. Some authors suggest that large-scale violence only arose with the spreading of agriculture and the building of complex societies. To shed light on this issue, we developed a model based on operatorial techniques simulating population-resource dynamics within a two-dimensional lattice, with humans and natural resources interacting in each cell of the lattice. The model outcomes under different conditions were compared with recently available demographic data for prehistoric South America. Only under conditions that include migration among c…

L’avvio della ricerca empirica in campo educativo in Italia: il contributo di Calonghi e Visalberghi

2014

Mentre la filosofia dominante in Italia alla fine della seconda guerra mondiale non era favorevole alla sperimentazione pedagogica, alcune iniziative, tese a innovare in senso attivistico i contenuti e i metodi dell’insegnamento scolastico, costituirono le cause remote dell’avvio dello studio dell’educazione con il metodo positivo. Esse facilitarono l’azione dei pionieri della ricerca empirica in campo educativo, che si sviluppò in Italia a partire dagli anni cinquanta del XX secolo per tre cause prossime: l’influsso delle sperimentazioni realizzate nelle scuole degli USA, la diffusione del pensiero di Dewey, l’impulso dato dall’Istituto Superiore di Pedagogia dei Salesiani allo studio dell…
