SEDIMENTOLOGICAL MAP OF THE GULF OF CAGLIARI – SOUTH SARDINIA, ITALY
No full textThe SEDIMENTOLOGICAL MAP OF THE GULF OF CAGLIARI IS PRESENTED. The reseach is based on 323 sediment samples, collected during 7 oceanographic cruises carried on in the context of the following project: - "Environmental control system and management of the coastal and marine area of the Gulf of Cagliari" - Italian University and Research Office (M.I.U.R.); - CAR.G. Project - "Geological Map of Italy, 1:50,000 scale" - Sheet 557 "Cagliari" and sheet 566 "Pula".
The purpose of this research is to finally contribute to reaching a thorough understanding of the sea bed in the area between Capo Spartivento and Capo Carbonara, improving the knowledge of the present accumulation, transport and sedimentation processes on the inner shelf.
The preliminary phase consisted in the examination of previous data: sonar data, seismic data, sedimentary data derived from surveying carried out by the Marine and Coastal Geology researchers of Cagliari University - Earth Science Department over the last 15 years; followed by the digital cartographic base drawing, geo-referred in 1:50,000 scale.
These objectives were reached by revising acoustic data (Side Scan Sonar, Multi-Beam and Single-Beam) and seismic data (Sub Bottom Profiler e Sparker). As cartographic bases we used the Regional Technical Maps (CTR, Regione Autonoma della Sardegna, 1998), in 1:10,000 scale, revised with the Ortophotos, in 1:10,000 scale (Regione Autonoma della Sardegna, 2006) and compared with previous Ortophotos from 77, '98, '02.
In the sea area we used the Italian navy nautical maps (I.I.M.I.) and new acoustic data obtained during the last two years surveying (2005 and 2006 Gulf of Cagliari Campaign; 2006 and 2007 "Santa Margherita" and "Solanas" Campaign and 2006/07 "Cagliari Sub" Campaign).
New sedimentary samples were collected with a Van Veen sampler (5 litres), 163 samples in the gulf area and further 54 samples were collected onshore and on the shoreline in detailed areas. Afterwards underwater and direct dip (ARA) samples were collected. In addition, 106 precedent samples were examined.
Every sample was analysed (grain size and composition) and classified (Udden-Wentworth scale) and facies association were recognised.
All cartographic, acoustic and sedimentary data collected, was revised, processed and digitized.
The data was added in a single G.I.S. file used to create the "SEDIMENTOLOGICAL MAP OF GULF OF CAGLIARI - South Sardinia, Italy" (1:50,000 scale), that represents the sea bed facies association

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Full text linkIncluded in the scope of workplace safety is that relating to potential accidents, i.e. the harmful consequences for human health crossed with the work environment factor. In the study of the determinism of these accidental events, it is important to achieve a biomechanical balance between two main elements: the human and the work environment (consisting of the physical, chemical and environmental factors, i.e. the equipment and what generates its use). Considering the most recent statistically recorded incidents, our analysis has focused on the accident sphere proper, where an imbalance in the above-mentioned binomial triggers the activation of multiple disciplines that actively and pro-actively study the event and assess its sequelae, in all possible facets (economic, engineering, clinical, medical-legal)
