Some critical remarks on the paper “A note on the metrizability of tvs-cone metric spaces” / Некоторые критические замечания о работе «Заметки о метр…

2018

This short and concise note provides a detailed exposition of the approach and results established by (Lin et al, 2015, pp.271-279). We show that the obtained results are not particularly surprising and new. Namely, using an old result due to K. Deimling it is indicated that tvs-cone metric spaces over solid cones are actually cone metric spaces over normal solid cones. Hence, there are only cone metric spaces over normal solid cones or over normal non-solid cones. One question still unanswered is whether an ordered topological vector space with a non-normal non-solid cone exists. / В представленных, в данной статье, заметках приведен подробный обзор методов и полученных результатов исследо…

Production technology of early-Hellenistic lime-based mortars from a Punic-Roman residential area at Palermo (Sicily)

2016

The topic of this study was the mineralogical and petrographic characterization of lime-based mortars of Hellenistic-Roman age (3rd century BC), taken from a residential area located in the historical centre of Palermo, near the walls of the Punic-Roman Neapolis, recently brought to light by excavations carried out by the Soprintendenza BB.CC.AA. of Palermo at Palazzo del Gran Cancelliere (Palermo). The collected mortars have been analyzed by optical microscopy (PLM), X-ray powder diffraction analysis (XRPD) and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of temper and binder, temper size distrib…

Caracterización clínica, biométrica y molecular de la miopía patológica en relación a los miopes bajos y emétropes

2021

Título: Caracterización clínica, biométrica y molecular de la miopía patológica en relación a los miopes bajos y emétropes. Introducción: la miopía conforma un estado refractivo patológico donde el poder dióptrico del sistema óptico ocular es mayor que el necesario para su longitud axial. Su principal síntoma es la disminución de la agudeza visual lejana, y si bien en la mayoría de los casos no acarrea alteraciones estructurales apreciables, aproximadamente un 3% de los pacientes miopes alcanzan errores refractivos elevados que se asocian a daños estructurales en diferentes niveles de la anatomía ocular. Determinar las variables que condicionan una situación u otra, así como los factores pr…

Characterization of component pigments in a mixture

2011

This work is part of Raman spectra database constitution of pigments and materials of Cultural Heritage interest for polychrome artworks characterization. The colours of paintings are often obtained mixing pigments of palette artist’s. The attribution of a work of art to an author and the individuation of fakes are related to the identification of used pigments and also to the detection of mixture constituents. The main research objective is the extension of PH3DRA laboratory database with information useful to detect not only each single pigment but also quantitative data regarding its relative ratio in the examined mixture. The availability of spectra as revealed represents the primary li…

Il “ciclo vitale” di un’élite cittadina: il patriziato di Messina in età moderna

2009

Una forte mobilità sociale – con i suoi processi di rimescolamento e rinnovamento – caratterizza la storia della Sicilia moderna, con alcune fasi di particolare accelerazione: nei decenni tra fine ’500 e inizio ’600, durante i quali come «mai forse nella storia dell’isola la nobiltà [feudale] si acquistò con tanta facilità» (Cancila); e in quelli a cavallo del 1700, “alba” di quei “gattopardi” (Gallo), che avrebbero dominato la scena politica negli anni difficili di dominazioni straniere brevi e precarie. Lo dimostrano, tra i tanti, due fenomeni che coinvolgono dalla base al vertice tutta la piramide sociale dell’isola: la vivacità del mercato dei titoli e degli onori (don, nobile, regio ca…
