  • "Sulle rotte dei genovesi d'oltremare: aspetti linguistici e storico-culturali, tra Mediterraneo e spazi globali"

Intervention n°1: Prof. Chiara Fedriani and Prof. Irene De Felice

Intervention n°2: Prof. Paolo Calcagno


Intervention n°1:

The presentation discussed some linguistic and cultural-historical aspects that emerge from notarial texts written in Latin and related to the colonies of Chios and Cyprus, established by the Genoese who plied the eastern Mediterranean between the 13th and 15th centuries. Through these texts, we dwelled on the multicultural landscape of the Mediterranean, a highly mobile and interconnected cultural-historical area, of which the sea represents, according to Braudel, “the greatest existing document of its past life”, and which has long aroused the interest of linguists interested in the history of linguistic contact, the development of lingua franca, and multilingual repertoires. In this context, the Genoese played a fundamental role through the construction of overseas economic activities that led to the development of settlements and linguistic islands, a sort of ‘other Genoas’, as defined by Toso (2020: 31), the most prominent scholar in this field. The research project is funded by the CARIGE Foundation and promotes the valorization of local documents produced at a time of great historical expansion of Genoese maritime and commercial power.

"The port of Genoa" (Cristoforo De' Grassi, 1481)


Intervention n°2: 

Since the early modern period, the operations of Ligurian merchants, divided among shipping, finance and trade exchanges, extended from the Mediterranean and the Black Sea to the oceans. After Columbus’ discovery, owing to the prominent position Ligurians occupied in the Iberian peninsula since the Late Middle Ages, they managed to monopolise the global circulation of silver. Part of the wealth generated in this way was reinvested in shipping: strong of the political support granted by the Republic’s government, ruled by a cohesive “navalist” faction, throughout the 17th century, some dynamic entrepreneurs envisaged the creation of companies to trade with the East Indies and Brazil, others reopened Genoa’s antique commercial networks with the Ottoman Empire, others took an active part in the dramatic venture of the Atlantic slave trade.

The disposal of fiberglass pleasure-boat:    

an integrated system for their demolition and sustainable disposal 


Interventions by: 

Dr. Davide Telleschi 

Dr. Matteo Covini 

Introduction by Prof.Arch. Mario Ivan Zignego


Fiberglass nowadays is still difficult to reuse / recycle and challenging to dispose of, which is why the nautical world is looking for a worthy replacement or an industrialized process that allows for its proper treatment at the end of life. 

The “boat object” can be defined as a complex system where the fiberglass outer shell is nothing but the container of an enormous heterogeneity of materials. For this reason, the key to yacht recycling is based on the mechanical separation of base components and raw materials, together with a thermal demolition of the composite material to separate the reinforcing fibers from the matrix. The goal is to optimize the percentages of raw-secondary materials re-introduced into the market, a mission that can be reached by finding a link between those who build yachts and those who deal with their disposal, thus closing the life cycle of the fiberglass units with a view to a circular economy. 

During the conference, the integration of two experimental processes was therefore proposed: 


Post Shredded Separation (PSS) 

automated separation by mechanical filters of the crumbs resulting from the shredding of a yacht in order to arrive at a collection of raw materials separated ready for recycling;

  • Thermal decomposition process of fiberglass: 

non-oxidative thermal demolition of the composite material extracted, capable of separating the glass fibers from the resin

Intervention n°1: Prof. Enrico Rizzuto - DITEN

Intervention n°2: Prof. Corrado Schenone - DIME

Intervention n°3: Prof. Tatiana Pais - DITEN

Intervention n°4: Prof. Stefano Gaggero - DITEN


Intervention n°1: On board acoustic comfort and external noise impact for vessels 

The presentation covered the basic elements of noise propagation, with specific reference to ships and nautical units. The elements of the propagation path were identified in the three cases of noise propagation in the interior of the unit and outside, both in air and in water. 

Aspects and problems in the characterization of sources, of the transmission path and of the acoustic impact on receivers were examined together with the main countermeasures that can be adopted to limit noise transmission. 

UNIGE activities in the field were briefly introduced 


Intervention n°2: Noise emissions and airborne acoustic impact 

Maritime transport for both passengers and freight is continuously increasing and, consequently, the global attention toward its sustainability is growing. Ships offer advantages in terms of environmental impact compared to other transportation systems but the increasing traffic volume is expected to increase pollutants. Noise produced in port areas has been neglected for too long. Only recently citizen complaints are emerging for some of the main ports in the Mediterranean. However, port noise prevention and management is difficult as knowledge on specific sources is very limited in the literature. Furthermore, on field measurements are difficult to be performed given the complexity of the port area, where multiple types of sound emitters mix and confuse each other. Noise maps represent a first important step in order to align ports to the requirements set by the Environmental Noise Directive to the transportation infrastructures.
