Biocompatibility and biodegradability of electrospun phea-pla scaffolds: Our preliminary experience in a murine animal model

2012

We obtained a nano-fibrillar scaffold starting from a polymeric solution which, through electrospinning, gave a biodegradable material with optimal mechanical features and the capacity to allow cell adhesion. In this paper we report the in-vivo application on a murine animal model of two electrospun biodegradable materials, specifically designed to create tubular structures. In one case PHEA-PLA was co-spun with silk fibroin (Fibro-PHEAPLA) by a parallel electrospinning process to obtain a scaffold with two different polymeric fibers. In the other case, PHEA-PLA was mixed with polycaprolactone (PCLPHEA-PLA) to obtain a hybrid fibers scaffold. The in-vitro assay showed fibroblast colonizatio…

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…

Using differential geometric LARS algorithm to study the expression profile of a sample of patients with latex-fruit syndrome

2011

Natural rubber latex IgE-mediated hypersensitivity is one of the most important health problems in allergy during recent years. The prevalence of individuals allergic to latex shows an associated hypersensitivity to some plant-derived foods, especially freshly consumed fruit. This association of latex allergy and allergy to plant-derived foods is called latex-fruit syndrome. The aim of this study is to use the differential geometric generalization of the LARS algorithm to identify candidate genes that may be associated with the pathogenesis of allergy to latex or vegetable.

FDA dimension reduction techniques and components separation in Fourier-transform infrared spectroscopy

2020

FTIR spectroscopy is a measurement technique used to obtain an infrared spectrum of absorption of a solid (or a liquid or a gas), for the characterization of specific chemical components of materials. When repeated measures are taken on samples of materials, the result is a collection of spectra representing a set of samples from continous functions (signals) defined in the domain of the frequencies. An unifying approach to the study of a collection of FTIR spectra is proposed to deal with the presence of random shifts in the peaks, the identification of representative spectra and finally the characterization of the observed differences: in the functional data framework, the performance of …

Measuring sustainable economic development through a multidimensional Gini index

2016

This paper analyses the evolution of sustainable economic development inequality in Italy as regards the efforts made by each administrative Region, as a response to the main EU policies issued by the environmental and energy sector. For this purpose a multidimensional generalization of the Gini index has been performed, taking into account two different dimensions (energy and environment), in a time frame of six years (2008-2013). The multidimensional Gini results confirm the positive effect recorded by certain EU policies in determining a reduction in the inequality levels among the Italian Regions. A counterfactual analysis further underlined the relevant role played by the energetic dim…

Defining and measuring the development of a country over time

2012

This paper introduces the concept of harmonic growth as an extended acceptation of the notion of development, and discusses its measurement via the Harmonic Growth Index (HGI). The growth is seen as harmonic when the behaviour of a benchmark time series, which here is a measure of wealth, such as per capita GDP, is followed by a similar pattern in socio-economic series. Unlike most widely used indicators in the literature, which take into account the measurement of development over a single time, HGI measures the degree to which a social indicator’s time series pattern matches with the GDP’s. The index is a function, ranging in [0, 1], of the coefficients of the uniform B-splines fitted to …

Mechanisms of the Embedding of Extortion Racket Systems: The case of Cosa Nostra

2017

The chapter summarises some of the research undertaken in the EU project GLODERS which is directed towards investigating the dynamics of extortion racket systems (ERS) of which the Sicilian Mafia is but one example (http://www.gloders.eu/). Before describing in more detail the principal formal characteristics of the Mafia-type organizations and the ways in which the extortion racket system works in a certain territory it is necessary to briefly outline what is a mafia-type organization and what we mean when we talk about the extortion racket system. The chapter propose an analysis of the mechanisms of the process of extortion in Sicily.
