Dinamiche di popolamento e processi di trasmissione culturale nel comprensorio madonita attraverso la ricostruzione della viabilità antica
2020
La ricerca sulle Madonie nasce con l’intenzione di approfondire l’evoluzione storica del popolamento sulla regione montana della Sicilia nord-occidentale. Il territorio, che solo in anni recenti è divenuto oggetto di più approfondite ricerche storico-archeologiche, si presenta estremamente ricco di risorse naturali e caratterizzato da un sostrato culturale variegato che abbraccia territori d’alta montagna, dediti ad una economia silvo-pastorale prettamente conservativa, e insediamenti costieri fortemente proiettati allo scambio e al commercio. A fine di comprendere lo sviluppo delle dinamiche d’insediamento di un’area molto estesa, si è proceduto anzitutto con la restituzione ipotetica dei …
Indagine sperimentale sui segnali sonori all’interno dei rotabili per la diagnosi dello stato dell’armamento ferroviario
2003
The maintenance of track provides an relatively frequent operations. A good maintenance-planning allows to reduce the interference between rail traffic and maintenance operations. It is necessary so to use a monitoring system of track conditions. In this paper is showed an indirect monitoring system that correlates track conditions and typical spectrum of in-cab noise. The first results of experimental survey are reported.
Detection of Parietaria Mottle Virus by RT-qPCR: An Emerging Virus Native of Mediterranean Area That Undermine Tomato and Pepper Production in Southe…
2021
Parietaria mottle virus (PMoV) is considered an emerging virus in many countries of the Mediterranean basin, especially on tomato and pepper crops. Symptoms on tomato leaves and fruits can be easily confused with those induced by cucumber mosaic virus (CMV) with necrogenic satellite RNA (CMV-satRNA), tomato spotted wilt virus (TSWV) or tomato mosaic virus (ToMV). Mixed infection of these viruses has been also reported in some tomato cultivars, with an increase in the complexity of the symptoms and severity of the disease. Although a specific serum and riboprobes have been produced, nowadays no sensitive diagnostic methods are available for the rapid PMoV detection. Here, we have developed a…
Modern Multispectral Sensors Help Track Explosive Eruptions
2013
Due to its massive air traffic impact, the 2010 eruption of Eyjafjallajokull was felt by millions of people and cost airlines more than U.S. $1.7 billion. The event has, thus, become widely cited in renewed efforts to improve real-time tracking of volcanic plumes, as witnessed by special sections published last year in Journal of Geophysical Research, (117, issues D20 and B9).
