The Area Of The Strait Reading Theories And Strategies For A Metropolitan Dimension
2016
Abstract Extending across a peninsular strip going from Gioia Tauro to Melito Porto Salvo on the Calabrian side, and from Milazzo to Giardini Naxos on the Sicilian side, the Strait of Sicily sees theAspromonte massif and the Peloritani mountain range as two facing stage sets of land sketching in the gulf a water piazza of a landscaping room. Described in the proposal by Giuseppe and Alberto Samona, Ludovico Quaroni, Antonio Quistelli, Sergio Musmeci, Paolo D’Orsi Villani and Leonardo Urbani, it outlines, in the county seats of Reggio Calabria and Messina, the prevalence of a Euclidean space, identifiable in the exact metrics given by the recurrence of the measuring step of the blocks drawn …
Etna. Miti e riti della "montagna" sacra
2019
L’Etna con la sua immensa mole fumante, la sua incessante attività vulcanica, il potere distruttivo e generativo delle sue lave, i suoi mutevoli paesaggi, ha costituito nei millenni un riferimento costante dell’immaginario isolano, offrendosi come inesauribile sorgente di affabulazione mitopoietica, teatro epico e lirico di vita e di morte, soggetto e scenario di riti, di miti, di leggende molteplici. Colosso dall’indole incostante e dalla potenza terrifica, vorace distruttore di tuguri e palazzi costruiti della sua stessa pietra, di campi e di piantagioni prima nutriti dalla sua stessa lava, l’Etna contiene e rappresenta, materialmente e simbolicamente, gli opposti: l’alto e il basso, la t…
Multiple solutions for quasilinear elliptic problems via critical points in open sublevels and truncation principles
2012
Abstract We study a quasilinear elliptic problem depending on a parameter λ of the form − Δ p u = λ f ( u ) in Ω , u = 0 on ∂ Ω . We present a novel variational approach that allows us to obtain multiplicity, regularity and a priori estimate of solutions by assuming certain growth and sign conditions on f prescribed only near zero. More precisely, we describe an interval of parameters λ for which the problem under consideration admits at least three nontrivial solutions: two extremal constant-sign solutions and one sign-changing solution. Our approach is based on an abstract localization principle of critical points of functionals of the form E = Φ − λ Ψ on open sublevels Φ − 1 ( ] − ∞ , …
Mapping snow density through thermal inertia observations
2023
Snow, as a fundamental reservoir of freshwater, is a crucial natural resource. Specifically, knowledge of snow density spatial and temporal variability could improve modelling of snow water equivalent, which is relevant for managing freshwater resources in context of ongoing climate change. The possibility of estimating snow density from remote sensing has great potential, considering the availability of satellite data and their ability to generate efficient monitoring systems from space. In this study, we present an innovative method that combines meteorological parameters, satellite data and field snow measurements to estimate thermal inertia of snow and snow density at a catchment scale.…
Technological Competence Is a Pre-condition for Effective Implementation of Virtual Reality Head Mounted Displays in Human Neuroscience: A Technologi…
2019
Immersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent to display, sound, motion tracking, navigation, ergonomic interactions, user experience, and computer hardware that should…
Remote sensing and climate data as a key for understanding fasciolosis transmission in the Andes: review and update of an ongoing interdisciplinary p…
2006
Fasciolosis caused by Fasciola hepatica in various South American countries located on the slopes of the Andes has been recognized as an important public health problem. However, the importance of this zoonotic hepatic parasite was neglected until the last decade. Countries such as Peru and Bolivia are considered to be hyperendemic areas for human and animal fasciolosis, and other countries such as Chile, Ecuador, Colombia and Venezuela are also affected. At the beginning of the 1990s a multidisciplinary project was launched with the aim to shed light on the problems related to this parasitic disease in the Northern Bolivian Altiplano. A few years later, a geographic information system (GIS…
Contributo alla conoscenza floristica dei monti Sicani (Sicilia): resoconto dell’escursione del Gruppo di Floristica (S.B.I.) nel 2012
2015
The results of the excursion of the “Gruppo di Floristica” of the Italian Botanical Society held in the Sicani Mountains (CW-Sicily) on May 3-6, 2012, are here presented. During the research a total of 532 taxa was recorded. Three of them, the native Rosa squarrosa and the alien Phyllostachys aurea and Vitis ×koberi are new to Sicily, and 14 are new to the Sicani Mts. On the other side, we confirm the exclusion of Erica manipuliflora from the flora of the region.
Analysis of the bryophyte diversity of mountain ranges in Sicily.
2015
The focus of this study was an analysis of the bryophyte flora of the main Sicilian mountain ranges, i.e., Peloritani, Nebrodi and Madonie mountains, located along the northern side of the Island, the Sicani mountains, located in the west-central Sicily and the Etna, the highest and most active volcano of Europe. The overall bryoflora consists of 504 taxa, 400 mosses and 104 liverworts and hornworts. It represent the 85.3% of the whole Sicilian flora; the mosses are referred to 37 families, the liverworts together with hornworts to 31 families. The phytogeographical analysis has shown the prevalence of the Mediterranean species, with the highest value on the Sicani mountains. It is notewort…
The role of traditional Erica arborea L. management practices in maintaining northeastern Sicily’s cultural landscape
2007
The tree heath (Erica arborea L.), a small evergreen tree found in the Mediterranean region and parts of Eastern and Central Africa, produces lignotubers that are highly valued for making smoking pipes. The Peloritani Mountains of northeastern Sicily are historically one of the most important areas in Italy for the production of these high quality lignotubers, known as briar root wood. In the past, tree heath shrublands were also an important source of charcoal. Erica arborea utilisation has declined dramatically during the past century, mostly due to the decreasing demand for smoking pipes, as well as the increasing frequency of wildfires and large-scale afforestation activities in this re…
Effects on the quality and nutritional traits of wood strawberry fruits in Sicily.
2011
In Sicily, the common woodland strawberry (Fragaria vesca) is spontaneous in the Madonie Mountains (554 m a.s.l.), Nebrodi Mountains (850 m) and Mount Etna (900 m). In this region, the main clone cultivated is ‘Fragolina di Sciacca e Ribera’, named after the towns where the crop originally developed. It is a Junebearing genotype and it is characterized by very small fruits, globose-conical shape, deep red colour, very soft flesh, strong aroma and flavor. Also ever-bearing clones are cultivated in Sicily where they are cropped for many months. Solid soluble content, total titratable acidity, total antioxidant capacity, total polyphenols and anthocyanins content were quantified in berry sampl…
