Seismogenic rotational slumps and translational glides in pelagic deep-water carbonates. Upper Tithonian-Berriasian of Southern Tethyan margin (W Sic…
2017
Abstract Soft-sediment deformation structures (SSDSs), which reflect sediment mobilization processes, are helpful to identify punctual events of paleoenvironmental stresses. In the upper Tithonian-Berriasian calpionellid pelagic limestone of the Lattimusa Fm. outcropping in the Barracu section (W Sicily), paleoenvironmental restoration reveals the occurrence of a deep-water flat basin, characterised by undeformed planar bedding, laterally passing to a gentle slope where the deformed horizons alternate with undeformed beds. Here, two types of gravity slides have been differentiated on the basis of different kinds of SSDSs, brittle deformation, involved lithofacies, geometry and morphology. T…
Synsedimentary-tectonic, soft-sediment deformation and volcanism in the rifted Tethyan margin from the Upper Triassic–Middle Jurassic deep-water carb…
2014
Abstract The Pizzo Lupo section (Sicanian Mts, central Sicily) is an Upper Triassic–Lower Jurassic condensed deep-water succession, where the relationships among synsedimentary tectonic, soft-sediment deformations, volcanism and lithological changes reflect the evolution of a rift-basin. The morphostructural setting of the studied basin appears as a gently dipping slope where a fault-delimited area (graben to halfgraben) was developed. The instability of the sea floor, related to the seismic shocks, was the cause of the gravity-driven deformational sedimentary structures (slumping, breccia channelized bodies). The partly stratified basaltic rocks, with disorganized and chaotic stratificatio…
Test B-Y glare
2016
El material es un archivo ejecutable, que permite instalar una aplicación para evaluar un índice de estés frente al deslumbramiento, comparando medidas de agudeza visual previa y posterior al deslumbramiento con una fuente de luz externa (600 luxes). Las medida de agudeza visual se realiza con una tarea de discriminación de orientaciones (el paciente debe describir la orientación de una letra E de Snellen), con estímulos modulados a lo largo de la dirección azul-amarillo de l modelo de Boynton. Los estímulos incluidos en la aplicación no son configurables, y están calculados asumiendo los datos de caracterización colorimétrica de un monitor particular, y por tanto, el programa sólo puede pr…
Natural Laboratories for Field Observation About Genesis and Landscape Effects of Palaeo-Earthquakes: a Proposal for the Rocca Busambra and Monte Bar…
2018
Earthquakes are phenomena that are still being learned by the scientific community, and poorly known, especially as regards the prevention, by the population. Having a more complete knowledge is a basic step in understanding the vastness and intensity of the destructive phenomenon that involves a great amount of people. The recent earthquakes occurred in Central Italy (L’Aquila and Amatrice earthquakes) are examples that demonstrate the importance of having knowledge about these phenomena to contrast their destructive effects. We present a geological field trip to recognise causes and landscape effects of palaeo-earthquakes recorded in the Mesozoic rock successions outcropping in Sicily. Th…
Birth and Early evolution of a Jurassic Escarpment: Monte Kumeta, Western Sicily
2002
The accurate reconstruction of the facies architecture in the Jurassic succession of Monte Kumeta, coupled with a detailed biostratigraphy, allow to define dynamics and genetic factors controlling the conversion of a Bahamian-type carbonate platform to a pelagic escarpment. A change from tidalites to oolites i.e. from the restricted, interior lagoon to a more open-marine sandy depositional environment, records the establishment of a basin south of the Monte Kumeta sector in late Hettangian-Sinemurian times. The oolitic limestones are overlain by earliest Carixian bioclastic grainstones and packstones with micritized grains and by wackestones with radiolarians and sponge spicules, organized …
Pathologist’s Findings after PTCA (The Mechanism of Angioplasty)
1991
Knowledge of the pathological changes induced by percutaneous transluminal coronary angioplasty (PTCA) is necessary to understand its complications.
Coronary Spasm in Patients Treated by Percutaneous Transluminal Coronary Angioplasty
1986
The appearance of coronary spasm during PTCA was analyzed in 140 consecutive patients with stable and unstable angina. Coronary spasm was found in 27 patients (19%) and was more common in unstable than in stable angina pectoris (22 versus 5 patients). While coronary spasm could be seen in the first coronary angiogram in 5/27 patients, it developed during the diagnostic procedure in 6/27 patients. In 16/27 patients coronary spasm was induced by the balloon or the guide wire itself.

Case study of the Kibera slum project
2011
The aim of this study is to explore social resilience and civic entrepreneurship in self-help organizations. The purpose is to find out how social resilience can be built through entrepreneurial activities. The issue is explored in a self-help organization in the Kibera slum. The intention is to contribute on the discussion on the best practises of self-help organization and the key elements behind their success or failure in developing countries. The thesis is divided into two main parts: the first one presents the key terms and a literary review on the concepts of social resilience and civic entrepreneurship. The second part is a case study on the cooperation of two non-governmental organ…
