A NOVEL APPROACH TO FULLY CHARACTERIZE FIBER NETWORK MORPHOLOGY OF PLANAR FIBROUS TISSUES AND SCAFFOLDS
2011
Comprendere come la struttura di uno scaffold influenzi la morfologia cellulare e predirne il comportamento meccanico sono divenuti obiettivi fondamentali nello sviluppo dei tessuti ingegnerizzati. In questo studio si presenta un algoritmo innovativo basato su analisi d’immagine. Vengono introdotti descrittori di micro architettura che identificano univocamente la topologia della rete di fibre: orientamento delle fibre, connettività, densità spaziale delle intersezioni e diametro. Le prestazioni dell’algoritmo sono state valutate utilizzando immagini di microscopio a scansione elettronica (SEM) di (1) scaffolds in poliestere uretano-urea prodotti per elettrospinning, (2) gel di collagene se…
The resonant state at filling factor {\nu} = 1/2 in chiral fermionic ladders
2017
Helical liquids have been experimentally detected in both nanowires and ultracold atomic chains as the result of strong spin-orbit interactions. In both cases the inner degrees of freedom can be considered as an additional space dimension, providing an interpretation of these systems as synthetic ladders, with artificial magnetic fluxes determined by the spin-orbit terms. In this work, we characterize the helical state which appears at filling $\nu=1/2$: this state is generated by a gap arising in the spin sector of the corresponding Luttinger liquid and it can be interpreted as the one-dimensional (1D) limit of a fractional quantum Hall state of bosonic pairs of fermions. We study its main…
Sex differences in food choices, adherence to dietary recommendations and plasma lipid profile in type 2 diabetes
2016
Background and aims Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. Methods and results We studied 2573 people, aged 50–75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, veg…
Latina e Valdelacalzada: sviluppi recenti e trasformazioni necessarie per un rinnovato rapporto tra paesaggio urbano e rurale
2020
This article gathers some reflections and suggestions that have been carried out throughout the workshop “Arquitectura construida y espacio habitado en los poblados de colonizatión de Italia y España” held in Palermo between the 21st and 22nd January 2020. The case studies that are here analysed and compared are Latina (ancient Littoria), in the Lazio region, Italy, and Valdelacalzada, in the Extremadura region, Spain. The two cities have in common the fundamental cross-shape relationship that characterises their primary urban foundation. Furthermore, both have been conceived and built under totalitarian regimes: Franco’s in Spain and Mussolini’s in Italy. Also, the reasons for their founda…
La programmazione del turismo delle regioni e la Regione Toscana
2022
With reference to the functions attributed to municipalities and provinces, the Tuscany Region has maintained a central role of planning and coordination of activities in the tourism sector. Local authorities and the various territorial levels of the trade associations of undertakings and workers are also formally involved in the preparation of regional planning. For this purpose, some regions have set up consultation tables to involve all public and private stakeholders in the sector. The article delves into the modalities of tourism planning, highlighting the training process and the laws of reference.
Agriculture and tourism: economic evaluation of sustainable land management
2022
The ways in which the agricultural landscape has been used and managed by man has resulted in substantial changes over time in relation to the economic changes and social needs of local communities. In recent times, thanks to the multifunctional vision of agriculture, growing interest has focused on the recreational aspects of the landscape as a function of its usability. This interest derives both from its importance, highlighted by numerous studies on this aspect, and from its link with rural tourism. The latter phenomenon is growing rapidly and is capable of triggering important processes of development and local growth. In this context, the present study highlights some preliminary cons…
Revista española de drogodependencias
2008
La valoración de la calidad de vida se ha convertido en la investigación clínica en uno de los más utilizados indicadores de resultados. Para ello, se precisa de instrumentos adaptados y validados al contexto donde han de utilizarse. El propósito del estudio es presentar, inicialmente, las características de las versiones existentes del IDUQoL (Injection Drug User Quality of Life Scale)) y ofrecer datos descriptivos y de adecuación del instrumento adaptado al español. Participan en el estudio 100 personas diagnosticadas de adicción a opiáceos incluidas en un programa de mantenimiento con metadona, quienes responden al IDUQoL en sus dos versiones de 17 y 21 dominios y otros dos instrumentos …

Sulla didattica del restauro dei monumenti in Italia nell'ultimo venticinquennio del Novecento
2013
Certamente l’attuale stato della didattica del Restauro dei Monumenti, nelle sedi universitarie in Italia, è anche il frutto del dibattito che coinvolse i docenti dell’area, nel periodo compreso fra il 1975 e la fine del XX secolo. Il saggio indaga il fecondo dibattito che proprio in quegli anni si sviluppò, grazie soprattutto all’impegno di Roberto di Stefano. Lo studioso, infatti, contribuì in maniera incisiva alla promozione di incontri periodici e dei contenuti da assegnare alla disciplina Restauro dei monumenti e per lo sviluppo della formazione degli operatori della conservazione del patrimonio culturale, in particolare architettonico e ambientale dell’Italia. Importante risulta pure …
Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
