Musica come Scienza dell'uomo. I caratteri del sapere musicale nel Settecento britannico

The departure point of the present work is the idea that in order to understand what music meant to British society in the Eighteenth-Century an interdisciplinary approach is necessary. Natural philosophy, moral philosophy, musical treatises and histories of music: all these sources concur both to the creation of a new idea about what music and its ‘science’ are, and to question the place which music ought to have in the realm of the Science of Man. The dissertation is divided into two sections. In the first one we will take into account philosophical sources (from John Locke, Joseph Addison and Lord Shaftesbury, to Lord Kames and Adam Smith), and we will examine their thoughts on music. In the second one we will deal with musical sources (from the Treatise of Musick of Alexander Malcom, to the Histories of Music of Charles Burney and John Hawkins) in order to show their connection with the philosophical literature before mentioned. The main aim of the work it to show that the development of specific philosophies of the human mind, such as the ones of John Locke and David Hume, did influence the way in which music was thought. Particularly we will point out the case of Adam Smith’s interpretation of instrumental music, which is heavily indebted to the humeian model of the human mind.

Phenotype and genotype characterization of Monilinia spp. isolates and preformed antifungal compounds in peach peel fruit at different developmental stages

The brown rot fungi belong to a group of fungal pathogens that causes considerable damage to cultivated fruits trees, particularly stone fruits and apples in the temperate regions of the World and during the postharvest with an important economic impact. In particular in Italy, it is important to monitor the Monilinia population to control economic losses associated to the peach and nectarine market. This motivates the research steps presented in this dissertation on Monilinia Italian isolates. The Monilinia species collected from stone fruits have been identified using molecular analysis based on specific primers. The relevant role of M. fructicola was confirmed and, for the first time, it was found also on apple fruits. To avoid the development of resistant strains and implement valid treatment strategies, the understanding of the fruit natural resistance during different developmental stages and the assessment of the Monilinia sensitivity/resistance to fungicides are required. The relationship between the inhibition spots and the phenolic compounds in peach fruit peel was highlighted in this research. Three methods were used to assess isolate resistance/sensitivity, the amended medium, the Spiral Gradient Endpoint Method (SGD) and the Alamar Blue method. The PCR was used to find possible mutation points in the b-tubulin gene that is responsible for fungicide resistance. Interestingly, no mutation points were observed in resistant M. laxa isolates, suggesting that the resistance could be stimulated by environmental factors. This lead to the study of the effect of the temperature on the resistance and the preliminary results of in vitro tests showed that maximum inhibition was observed at 30°C.
