Slope instability and erosional features of the Ligurian Margin
No full textThe recent conclusion of the Magic Project (Marine Geohazards along the Italian Coasts) (Chiocci & Ridente, 2011), the MALISAR Cruises (Migeon et. Al., 2011; Migeon et al., 2012) and the contribution of the data available at
the Universities of Genoa (IT) and Trieste (IT) allowed us to identify and study the large series of erosional and gravitative phenomena along the Ligurian continental margins. The dataset allowed us to relate the structural
evolution of the Ligurian Basin, the characteristics of the sedimentation, the erosive action of a dense canyon network and the gravitational phenomena (Corradi et al., 2002).
The Ligurian Sea is the northwestern portion of the Mediterranean Sea. It originated from the roto-translation of the Corsica-Sardinia Block and is connected to the Apennine orogenic dynamics (Fanucci & Morelli, 2000). The
complex geological evolution of the Liguran Sea brought to the division of this basin in different physiographic domains. The main one is the Valley of Genoa that separates the margin of the Alpine area from the Apennines one,
which developped in a portion of the newly formed chain. The evolution of the two margins, mainly controlled by extensional tectonics processes, was interrupted by compressional and/or transpressive reactivations, which gave
particular characteristics to the margins (Fanucci & Morelli, 2013; Sage et al., 2013; Sage et al., 2014).
The Alpine margin is characterized by high seismicity, high sedimention rate and steepness of the margin, determining massive and unstable sedimentary masses along the slope, which are carved by a dense network of
canyons.
It is in the western Liguria sector that these erosive features are extensively represented until the "Dorsal of Imperia", a structural element that runs parallel to the margin for about 50-60 kilometers. Its genesis can be attributed to
the effects of a compressive deformation and this structure isolated an intra-slope basin in which huge quantities of sediments were accumulated and drained by canyons and conveyed in the Valley of Genoa, through the
Canyon of Vado.
The continental margin between the City of Genoa and the Portofino Promontory is characterized by the two main canyons of the Ligurian Gulf: the Polcevera and the Bisagno canyons. These are in continuity with their
respective rivers and almost entirely eroded a thick Plio-Quaternary sequence.
The Apennine margin presents a less complex structure than the Alpine one (Fanucci & Morelli, 2006); however, large gravitative phenomena are present. The most important is the Portofino Landslide, located in front of the
corresponding promontory. It is mainly characterized by rotational slips and incipient detachment niches, stimulated by the erosion at the base by the Levante Canyon. This last, oriented along the Apennine tectonic lineations,
produces significant erosion, both on the head than along its way, which is almost parallel to the coast until its confluence in the Bisagno Canyon.

Shear strengthening of wall panels through jacketing with cement mortar reinforced by GFRP grids
No full textThis paper gives the results of a series of shear tests carried out on historic wall panels reinforced with an innovative technique by means of jacketing with GFRP (Glass Fiber Reinforced Plastics) mesh inserted into an inorganic matrix. Tests were carried out in situ on panels cut from three different historic buildings in Italy: two in double-leaf rough hewn rubble stone masonry in Umbria and L'Aquila and another with solid brick masonry in Emilia. Two widely-known test methods: the diagonal compression test and the shear-compression test with existing confinement stress. The test results enabled the determination of the shear strength of the masonry before and after the application of the reinforcement. The panels strengthened with the GFRP exhibited a significant improvement in lateral load-carrying capacity of up to 1060% when compared to the control panels. A numerical study assessed the global behavior and the stress evolution in the unreinforced and strengthened panels using a finite element code
L’analisi dell’impatto dei beauty standard sulla salute mentale delle persone socializzate come donne tramite la ricerca e le testimonianze delle arti visive
No full textThe aim of the following study is both to analyse and evalu-
ate the impact of beauty standards on feminine presenting
people’s mental health through visual arts as well as by
utilising a qualitative and quantitative methodological ap-
proach. The project will have two bibliographical parts: the
first one will have an art history insight and will be focused
on the role of women’s bodies in arts, which will be ana-
lysed through visual arts depicting women; it will also look
at how society and arts looked and viewed women, creating
an intersection between gender studies and social art history
through a feminist perspective; the second part will be fo-
cused on gender studies, specifically, the objectification of
feminine presenting people’s bodies by society – especially
by heterosexual men – the discrimination they went through
because of their gender identity and how chasing beauty and
being considered attractive is a constant in the lives of femi-
nine presenting people compared to masculine-presenting
ones. The methodology that will be used to carry the study
comprehend the conduction of two surveys: one addressed
to feminine-aligned and presenting people and the other to
masculine-aligned and presenting ones in order to evaluate
the differences in the impact of and the importance given to
beauty standards and also how much beauty pressure affects
their daily lives and life choices in general (e.g. deciding
against going to the sea, eating certain foods, going on a diet
or not wear some kind of clothes)

No full textReinforcement of wood with natural fibers
No full textThis paper describes an experimental programme which examines the reinforcement in flexure of timber beams with composite materials based on natural fibers in the form of fabrics made from hemp, flax, basalt and bamboo fibers. The industrial use of natural fibers has been continuously increasing since 1990s due to their advantages in terms of production costs, pollution emissions and energy consumption for production and disposal. The technique allows the reinforcement of the intrados of beams, avoiding the dismantling of the overlying part of the structure with significant savings in terms of costs and work time. The test program consists of three phases incorporating 45 beams. The bending tests on the wooden elements made it possible to measure the increase in capacity and stiffness resulting from the composite reinforcement. This was applied to beams, creating different arrangements and using different quantities (number of layers). Despite the diversity of the various tests carried out, the results obtained in some cases showed significant increases in terms of load-carrying capacity and in deflection ductility
