Green coffee, bioactive compounds’ analysis of experimental cultivation in Sicily: a new frontier in the Sicilian food sector

2023

Recently, climate change represents a new possibility for tropical cultivars fruit in Mediterranean areas. The focus of this work is the evaluation of the real possibility of coffee cultivation in Sicily, like coffee plants grown in tropical and subtropical regions. The objective was to evaluate plant adaptation to our climate and to study the chemical qualities of green coffee pulps and seeds: total phenolic content, antiradical capacity, fatty acids, amino acids, alkaloids, vitamins, proximate composition, polyphenolic profile and other bioactive compounds of cosmetic, pharmaceutical and agrary interest. Temperature, light and vegetative growth of Coffea arabica L. cv. “Caturra” plants we…

Terrorismo yihadista: un protocolo de evaluación del riesgo de radicalización y de comisión de atentados

2019

El objetivo principal de la tesis es elaborar un protocolo de evaluación integral del riesgo de radicalización y de comisión de atentados yihadistas. Para alcanzar este propósito, la investigación se estructuró en dos partes diferenciadas. La primera consistió en una revisión bibliográfica de la literatura internacional sobre el fenómeno del terrorismo yihadista. Se realizó una fundamentación teórica sobre los factores de riesgo de radicalización y de comisión de atentados, así como de los protocolos teóricos y empíricos existentes al respecto. La segunda acogió una investigación empírica original. Se confeccionó una extensa base de datos con todos los atentados de índole yihadista perpetra…

Increased conformational rigidity of humic substances by oxidative biomimetic catalysis

2005

A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(III) chloride, Fe(TDCPPS)Cl, was employed as a biomimetic catalyst in the oxidative coupling of terrestrial humic materials. High-performance size-exclusion chromatography (HPSEC), solid-state nuclear magnetic resonance (CPMAS-(13)C NMR), electron paramagnetic resonance (EPR), and diffuse reflectance infrared spectroscopy (DRIFT) were used to follow conformational and structural changes brought about in different humic materials by the oxidative coupling. Increase in apparent weight-average molecular weight (Mw(a)) occurred invariably for all humic substances with the oxidative polymerization catalyzed …

Copolymerization of Vinylidene Fluoride and Acrylic Acid in Supercritical Carbon Dioxide

2010

The free-radical copolymerization of vinylidene fluoride (VDF) and acrylic acid (AA) was carried out in supercritical carbon dioxide using both precipitation and dispersion techniques in the presence of an ammonium carboxylate perfluoropolyether compound. Formation of a copolymer was confirmed by variable contact time CP MAS NMR spectroscopy. Macromolecular matrices were significantly enriched in AA with respect to the initial feed composition and we found that the nonfluorinated monomer has a much higher reactivity ratio with respect to VDF. The cumulative concentration, crystallinity, and water affinity of the synthesized copolymers could be modified changing the initial feed composition,…

"Io ho ragione; tu sei morto!" Su terrorismo e radicalizzazione

2018

Il contributo analizza il radicalismo come presupposto ideologico del terrorismo, proponendo un'analisi concettuale e criminologica delle diverse possibili forme di radicalizzazione e dei suoi rapporti con la violenza terroristica. Vi si analizzano altresì possibilità e limiti di de-radicalizzazione e contro-radicalizzazione quali strategie di contrasto al terrorismo alternative rispetto alla coercizione penale. The paper focuses on radicalism as the ideological background of terrorism, by putting forth a conceptual and criminological analysis of the different forms radicalization can take as well as of its relationships with terrorist violence. The paper also analyzes de-radicalization and…
