Risultati di azioni di rimboschimento in diversi contesti pedoclimatici siciliani
2022
Nell’ambito delle attività sviluppate dalla regione siciliana nella redazione del Piano Forestale Regionale 2009- 2013, negli anni 2006/2007 sono stati realizzati 8 campi sperimentali in diversi contesti pedoclimatici siciliani (Bioclima: mesomediterraneo e supramediterraneo. Substrato: alluvionale, argilloso, calcareo, flyshioide, sabbioso/ siliceo) in 5 province siciliane (Agrigento, Enna, Messina, Palermo e Trapani). La scelta delle specie da piantare è stata compiuta sulla base di una suddivisione del territorio siciliano per aree ecologicamente omogenee compiuta dal gruppo di Selvicoltura di UNIPA, e utilizzata per fornire uno strumento operativo e vincolante per i progetti forestali r…
Modifications of the vasopressin and ANP in the rat hypothalamic supraoptic nucleus during and after the physical exercise.

Modifications of atrial natriuretic peptide and vasopressin peptides in the rat hypothalamic supraoptic nucleus during resistance training
2010
Many studies have demonstrated the involvement of atrial natriuretic peptide (ANP) and vasopressin (VP) in the homeostasis of body fluids, but few studies have regarded the hypothalamic magnocellular neurosecretory system during physical exercises. The aim of the present immunohistochemical work is to study the activity of ANP and VP secreting neurons of the hypothalamic supraoptic nucleus during and after resistance training. The study was carried out in Wistar rats trained by a physical resistance-type exercise, using a rung ladder and a varying load fastened to the tail of each rat; the exercise lasted 20 min everyday for periods of 15, 30 and 45 days. Animal groups were sacrificed at th…
Fullerene-Polymers: Synthesis, Properties and Applications
2009
Written by an outstanding team of experts in the interdisciplinary areas of research, this book is based on a new classification of the different types of fullerene polymers according to their chemical structures. It covers all aspects, from different classes, to their synthesis and applications in material science. Of great interest to polymer and synthetic chemists, but also for material scientists and industrial chemists.

Organic Salts as Tectons for Self-assembly Processes in Solution
2022
The literature, covering the last decade, about the self-assembly processes of organic salts in conventional solvents was analyzed. In particular, data reported about imidazolium and ammonium salts have been considered. The analysis shows that these processes are highly determined by structural features of the salts. Indeed, besides the nature of the cationic head, features of the alkyl chain borne on the cation structure and its possible functionalization, as well as the nature of the anion play a pivotal role. These factors determine not only the nature of the solvent in which the process occurs but also the nature of the self-assembly mechanism. Consequently, the structure tunability of …
Walking through Soft Materials to Join Supramolecular Gels: An Overview about the Properties and Applications
The class of soft materials includes a large variety of species arising from self-assembly processes and held by non-covalent interactions. This confers peculiar features, allowing applications in very different fields.1 Among soft materials, supramolecular gel phases have aroused a surge of interest.2 These materials combine properties of liquid phase with the ones of a semi-solid network and the large number of gelator/solvent combinations can offer answer to issues of different nature.3 This lecture will show on overview about the obtainment and characterization of gel phases, in the attempt to understand the relationship working between gelator and solvent nature and gel phase propertie…
