Seismic stratigraphy of upper Quaternary shallow-water contourite drifts in the Gulf of Taranto (Ionian Sea, southern Italy)
2018
Abstract The occurrence of articulated seafloor morphology over continental shelf-upper slope environments, may result in a significant change in the patterns and intensity of basin-scale thermohaline circulation during eustatic sea-level fluctuations. These changes may cause, in turn, erosion, deposition and/or transport of sediments at the seafloor, to form shallow-water contourite drifts. Here we investigate this process in the NW sector of the Gulf of Taranto (Ionian Sea) during and following the Last Glacial Maximum (LGM), by integrating multibeam bathymetric data, ultra-high resolution seismic-reflection data and gravity core data. Sea level fall caused subaerial exposure of the summi…
Cuerpos y mutaciones en el cine de ciencia-ficción durante los años cincuenta
1994
El cine de ciencia-ficción de los años cincuenta nos ofrece un testimonio ejemplar por su candidez de hasta dónde el patrón humano rige sin apenas deslices toda suerte de metamorfosis. La misma situación del género es en extremo curiosa: lejos de la imaginería gótica y romántica que alimentó las producciones Universal, también se distancia de las afecciones víricas, las prótesis teratológicas y la robótica de cuño informático que asaltan el cuerpo haciéndolo estallar en el moderno cine de terror.
Methods for studying coastal bivalves in a changing world : A review and implications for management
2021
Master's thesis in Coastal ecology (BIO501) Anthropogenic activities such as pollution, CO2 emission, and overfishing, are among leading reasons for global environmental change and negative impacts on the marine environment including loss of biodiversity. Marine bivalves are an example of species that suffers from such consequences while they have high value in both aquaculture and marine ecosystems. With the existence of many threats including overharvesting, invasive species, parasites, and diseases, coastal bivalves such as flat oysters (Ostrea edulis) and blue mussels (Mytilus spp) are in many places endangered. The existing knowledge gaps in the historic and current distribution, howev…
Do cold-water corals spatially correlate with submarine canyons in the Bay of Biscay? : A GIS study analysing the spatial distribution of cold-water …
2020
Master's thesis in Coastal ecology (BIO501) The seascape of the Bay of Biscay is a mysterious place. It is located to the west of France and the north of Spainand is often defined as well-differentiated geomorphological unit. The continental margin of the BoB is incised with many submarine canyons and is also thought to be a hotspot for cold-water corals.Unfortunately, it is an area under high anthropogenic pressure where intense fishing activity, bottom trawling especially, is causing major disturbances to benthic habitats such as cold-water corals. Cold-water corals have been well studied along the European margin and have more frequently been recorded in the northeastAtlantic than any ot…
The Calabrian Stage redefined
2008
The name Calabrian was introduced in the geological literature by the French stratigrapher Maurice Gignoux in 1910, and later described in his important monograph (633 pages) "Les formations marines pliocènes et quaternaires de l'Italie du sud et de la Sicile" published in 1913. Detailed data were provided on several sections (Santa Maria di Catanzaro, Caraffa, Monasterace, Palermo) and on their fossil content. The Calabrian Stage has commonly been used for over fifty years as the oldest subdivision of the Quaternary, notably in the time scales of Berggren & van Couvering (1974) and Haq & Eysinga (1987). However, after the GSSP for the Pliocene/Pleistocene boundary (P/P) was approved by INQ…

Immaginario, narrazioni e condivisione online tra i backpackers: una prospettiva geografica
2023
Il backpacking è un modo di viaggiare che spesso si pone in contrapposizione al turismo mainstream, non solo per il suo generalizzato rifiuto dei classici circuiti standardizzati, ma anche per l’interesse assegnato ai percorsi naturalistici e agli stili di vita delle comunità visitate. Inoltre, a queste istanze negli ultimi decenni si sono aggiunte quelle relative alla sostenibilità ambientale e sociale del viaggio: per molti backpackers ciò si lega a un’etica condivisa dell’esperienza dell’alterità che, rispetto ad altre motivazioni, può assumere maggiore priorità. Tuttavia, nonostante le premesse, in molti casi il backpacking scende a compromessi con l’industria del turismo globale, anche…
Backthrusts and passive roof duplexes in fold-and-thrust belts. The case of Central-Western Sicily based on seismic reflection data
2012
Seismic reflection profiles crossing the area bounded by the M. Kumeta Ridge and the M. Maranfusa-M. Galiello-Rocca Busambra morphostructural feature (central-western Sicily) were used to constrain the deep structural setting of the Sicilian-Maghrebian fold-and-thrust belt (FTB). By integrating seismic, field and well data, we attempted to correlate outcropping and deep-seated contractional structures, shedding light on the internal geometries of the thrust system. Results of the new seismostratigraphic analysis presented in this paper reveal structural variations along the tectonic edifice. This suggests dividing the study area into two sectors: the western sector is characterized by forel…

Use of arms - influence to human balance during perturbation
2014
Tämän Pro gradu –tutkielman tarkoituksena oli selvittää, miten käsien käyttäminen tai käyttämättömyys vaikuttaa ihmisen tasapainon korjaamiseen äkillisessä horjutus (häiriö) tilanteessa. Tutkimukseen osallistui viisi vapaaehtoista koehenkilöä (32 +/- 11 vuotta). Tutkimuksen testiprotokollassa tasapainon korjaamiseksi häiriötilanteessa, henkilö asetettiin seisoman juoksumaton päälle, joka liikahti 0.2 metriä eteenpäin, anterior-suunnassa (nopeus 0.24 m/s). Tutkimuksessa käytettiin kahta eri tilaa: kädet ja ei kädet –tila, missä koehenkilö sulki kätensä vartalon eteen puuhkaan. Tasapainoa mitattiin juoksumaton voimalevyltä ja koehenkilön painopisteen muutokset…
