COMPARAZIONE DEI PROFILI METABOLICI DI VARIETÀ DI CILIEGIO DOLCE (Prunus avium L.) MEDIANTE TECNICHE DI METABOLOMICA UNTARGETED

La diffusione di cultivar altamente produttive ha influito negativamente sulla tutela dell’agro-biodiversità di Prunus avium L. determinando disinteresse nei confronti di varietà meno produttive ma meritevoli di attenzione per il valore delle loro caratteristiche organolettiche e del relativo patrimonio genetico. Il mondo scientifico ha mostrato interesse nei confronti di tale tematica e ha condotto azioni di conservazione in situ ed ex situ per preservare il germoplasma ancora esistente. La presente ricerca analizza l’agrobiodiversità del ciliegio dolce in relazione alla diversa composizione metabolomica dei frutti, espressione del genotipo che le caratterizza. L’attività di ricerca svolta…

Assessment of the Inter-Batch Variability of Microstructure Parameters in Topical Semisolids and Impact on the Demonstration of Equivalence

2019

Demonstration of similar microstructure is essential for demonstrating the equivalence of generic topical products since the microstructure of semisolids may affect the drug release. The objective of this study was to compare the microstructure-defining physical parameters of different batches of a reference ointment containing calcipotriol and betamethasone (Daivobet 50 &micro

Differentiation among dairy products by combination of fast field cycling NMR relaxometry data and chemometrics

2021

A set of commercial milk and Sicilian cheeses was analysed by a combination of fast field cycling (FFC) nuclear magnetic resonance (NMR) relaxometry and chemometrics. The NMR dispersion (NMRD) curves were successfully analysed with a mathematical model applied on Parmigiano-Reggiano (PR) cheese. Regression parameters were led back to the molecular components of cheeses (water trapped in casein micelles, proteins and fats) and milk samples (water belonging to hydration shells around dispersed colloidal particles of different sizes and bulk water). The application of chemometric analysis on relaxometric data enabled differentiating milk from cheeses and revealing differences within the two sa…

Imprenditori si nasce o si diventa? La rilevazione delle attitudini imprenditoriali: modelli di misura ed evidenze empiriche

2014

Il lavoro si propone di effettuare una rassegna dei principali modelli e strumenti di misura per la valutazione delle attitudini imprenditoriali. vengono proposti alcuni confronti tra diverse indagini empiriche effettuate in differenti contesti territtoriali

Violenze “di genere” e violenze “sulle donne”: problemi di definizione e di rilevazione empirica

2020

Il capitolo punta a problematizzare gli aspetti definitori del concetto di “violenza di genere” e quelli legati più strettamente alla sua rilevazione/misurazione, cercando di fornire un contributo all’utilizzo delle statistiche sul tema in maniera avveduta e consapevole. The chapter aims to problematize the defining aspects of the concept of "gender violence" and those related more closely to its detection / measurement, trying to provide a contribution to the use of statistics on the subject in a prudent and conscious manner.

Integrative Strategies in Mixed Methods Research

2020

Despite the critical role of integration as a methodological concept in mixed methods studies, researchers lack a theory for integrating. In this article, we introduce the concept of integrative strategy by analyzing three mixed methods rehabilitation-related studies. These studies represented an analytical strategy based on a multiperspective stakeholder approach, a theory-bound analytical strategy, and a theory-oriented synthesizing strategy. We define integrative strategy as a process in which the system of relations within the study is explicated and justified in accordance with the research purpose and phenomenon. This article contributes to mixed methods research by providing a novel…

Classification of Targets Using Statistical Features from Range FFT of mmWave FMCW Radars

2021

Radars with mmWave frequency modulated continuous wave (FMCW) technology accurately estimate the range and velocity of targets in their field of view (FoV). The targeted angle of arrival (AoA) estimation can be improved by increasing receiving antennas or by using multiple-input multiple-output (MIMO). However, obtaining target features such as target type remains challenging. In this paper, we present a novel target classification method based on machine learning and features extracted from a range fast Fourier transform (FFT) profile by using mmWave FMCW radars operating in the frequency range of 77–81 GHz. The measurements are carried out in a variety of realistic situations, including p…

Pokémon GO 2016: Exploring Situational Contexts of Critical Incidents in Augmented Reality

2016

Pokémon GO, an augmented reality mobile game, captured the attention of millions of people around the world in July 2016. Various sources from around the globe have reported both positive and negative incidents and outcomes related to the game. Some of the incidents have been particularly remarkable for the player, i.e., critical incidents. A critical incident is a single experience, which a person perceives or remembers as unusually positive or negative. Critical incidents typically are highly influential for human behaviour, and thus, important to study. Playing augmented reality games can take place in varying situational contexts. Situational context includes information that can be use…

An Exact Solution for the Level-Crossing Rate and the Average Duration of Fades of the Envelope of Sum-of-Cisoids Processes

2012

Authors version of an article published in the journal: Procedia Technology. Also available from the publisher at: http://dx.doi.org/10.1016/j.protcy.2012.03.004 Sum-of-cisoids (SOC) processes provide a physically and numerically appealing framework for the modelling and simulation of a wide class of mobile radio channels. This paper is concerned with the problem of finding a general solution for the level-crossing rate (LCR) and the average duration of fades (ADF) of the envelope of SOC processes. Exact expressions are derived for the LCR and the ADF by taking into account that the inphase component, the quadrature component, and the time derivatives of the inphase and quadrature component…
