Searching the most appropriate sample pretreatment for the elemental analysis of wines by inductively coupled plasma-based techniques.

2008

Different sample preparation methods were evaluated for the simultaneous multielement analysis of wine samples by inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). Microwave-assisted digestion in closed vessel, thermal digestion in open reactor, and direct sample dilution were considered for the determination of Li, Be, Na, Mg, Al, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Y, Mo, Cd, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Tl, Pb, and Bi in 12 samples of red wine from Valencia and Utiel-Requena protected designation of origin. ICP-MS allows the determination of 17 elements in most…

Physicochemical characteristics and phenotypic diversity of sicilian winter pumpkin (Cucurbita maxima) populations

2017

Six pumpkin genotypes (G1, G2, G3, G4, G5 and G6) were evaluated for their morphological, agronomical and physico-chemical properties under ecological conditions of Sicily (Italy). Considering the agronomical, morphological and physicochemical data including fiber, humidity, pH, total acidity, soluble solids, carotenoids, phenolic and ascorbic acid content, it was possible to differentiate among genotypes. The morphological analysis showed that the pumpkin genotypes did not have a homogenous morphology and present a large physico-chemical characteristic variability. Furthermore, high contents of carotenoids and dietary fiber, soluble solids, phenolic and ascorbic acid were observed with the…

La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo

2023

Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Within this framework Palermo and its historic center are no exception. The epicenter of these processes is represented here by the Kalsa district which since the early 2000s has been placed at the center of a precise strategy of culturally-based renewal called to drive the city's tourist renaissance (Vinci 2008). The culmination of this path came in 2018 when Palermo was named the Italian capital of culture and chosen as the venue for Manifesta one of the most prestigious traveling biennales of contemporary art. However the exponential increase in tourist arrivals in the last three years came to a halt with the outbreak of the pandemic which showed with unprecedented evidence the contradictions of the development strategies pursued in the historic center and the marks they leave on the territories. While this sudden interruption seems to offer an opportunity to radically rethink urban and cultural policies and find new curbs to the conditions of overtourism in which the historic centers of South European cities and beyond find themselves it could also prove to be an accelerator of the dynamics of commodification of these spaces representing the revival of tourism an easy escape route in times of crisis. The objective of this contribution is to critically explore the urban and social transformations that have crossed the Kalsa district of Palermo from the 2000s to the present using qualitative and quantitative techniques (analysis of statistical data in-depth interviews critical discourse analysis ...) with particular reference to the role that culture has played in these processes. While it is impossible to prefigure post-pandemic scenarios we will examine documents and discourses that trace possible development directions for South European cities and their historic centers.Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - Geografia

A Role for the β1-β2Loop in the Gating of 5-HT3Receptors

2005

Based on theTorpedoacetylcholine receptor structure, Unwin and colleagues (Miyazawa et al., 2003; Unwin, 2005) hypothesized that the transduction of agonist binding to channel gate opening involves a “pin-into-socket” interaction between αV46 at the tip of the extracellular β1-β2loop and the transmembrane M2 segment and M2-M3 loop. We mutated to cysteine the aligned positions in the 5-HT3Aand 5-HT3Bsubunit β1-β2loops K81 and Q70, respectively. The maximal 5-HT-activated currents in receptors containing 5-HT3A/K81C or 5-HT3B/Q70C were markedly reduced compared with wild type. Desensitization of wild-type currents involved fast and slow components. Mutant currents desensitized with only the f…

On finite involutive Yang–Baxter groups

2021

[EN] A group G is said to be an involutive Yang¿Baxter group, or simply an IYB-group, if it is isomorphic to the permutation group of an involutive, nondegenerate set-theoretic solution of the Yang-Baxter equation. We give new sufficient conditions for a group that can be factorised as a product of two IYB-groups to be an IYB-group. Some earlier results are direct consequences of our main theorem.

Morphological and agronomical characterisation of Sicilian bottle gourd Lagenaria siceraria (Mol.) Standley

2014

Local plant populations represent a valuable source of genetic variability. Lagenaria siceraria [Mol.] Standl. is a monoecious species of Cucurbitaceae grown in India and parts of the Mediterranean for its immature fruit and young leaves used as vegetables. The species is a high-value crop in Sicily where several landraces are grown in open field and in plastic greenhouse. The aim of this study was to characterise five Sicilian L. siceraria landraces (G1-G5), from a morphological and agronomical point of view. Genetic resource characterisation was carried out as a foundation for future conservation and breeding works. Fourteen qualitative and quantitative characters were assessed by using t…

Nanodiamond Theranostic for Light-Controlled Intracellular Heating and Nanoscale Temperature Sensing

2021

Temperature is an essential parameter in all biological systems, but information about the actual temperature in living cells is limited. Especially, in photothermal therapy, local intracellular temperature changes induce cell death but the local temperature gradients are not known. Highly sensitive nanothermometers would be required to measure and report local temperature changes independent of the intracellular environment, including pH or ions. Fluorescent nanodiamonds (ND) enable temperature sensing at the nanoscale independent of external conditions. Herein, we prepare ND nanothermometers coated with a nanogel shell and the photothermal agent indocyanine green serves as a heat generato…

A Neandertal dietary conundrum: Insights provided by tooth enamel Zn isotopes from Gabasa, Spain

2022

The characterization of Neandertals’ diets has mostly relied on nitrogen isotope analyses of bone and tooth collagen. However, few nitrogen isotope data have been recovered from bones or teeth from Iberia due to poor collagen preservation at Paleolithic sites in the region. Zinc isotopes have been shown to be a reliable method for reconstructing trophic levels in the absence of organic matter preservation. Here, we present the results of zinc (Zn), strontium (Sr), carbon (C), and oxygen (O) isotope and trace element ratio analysis measured in dental enamel on a Pleistocene food web in Gabasa, Spain, to characterize the diet and ecology of a Middle Paleolithic Neandertal individual. Based on…

A cubic defining algebra for the Links-Gould polynomial

2012

We define a finite-dimensional cubic quotient of the group algebra of the braid group, endowed with a (essentially unique) Markov trace which affords the Links-Grould invariant of knots and links. We investigate several of its properties, and state several conjectures about its structure.
