La 'Terra di mezzo' tra Siracusa e Augusta. Dalle poleisgreche alla citta lineare
2019
[SPA] El 'Dipolo urbano' de Siracusa·Augusta es un área estratégica para el futuro del sureste de Sicilia. Es un palimpsesto antrópico caracterizado por la presencia de un delicado paisaje natural y agrícola, sitios arqueológicos extraordinarios. contextos urbanos poblados y una industria petroquímica. El área geográfica es la zona costera incluida entre Augusta y Siracusa: una porción del territorio caracterizada por la presencia de calas y puertos naturales, limitada al oeste por la meseta calcarenítica de las montañas Climiti. En este palimpsesto tan degradado. la Escuela de Arquitectura de Siracusa ha estado estudiando posibles estrategias de recuperación y recualificación. A partir de …
A propósito del Bronce Atlántico y el origen de los calderos de remaches peninsulares
2002
[ES] Los calderos atlánticos de remaches de la Península Ibérica son datados con frecuencia en los ss. VIII-VII, aunque recientes publicaciones plantean que el origen de esta producción metálica en ámbito peninsular podría ser anterior. Intentamos mostrar, sobre la base de contextos estratigráficos y dataciones radiocarbónicas, que los calderos atlánticos de remaches aparecen en la Península Ibérica en el transcurso de los ss. XI-X cal BC.
Epidemiology of intensive care unit-acquired sepsis in Italy: Results of the SPIN-UTI network
2018
Background. Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project. Study design. Prospective multicenter study. Methods. The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Results. During the five editions of the SPIN-UTI project, from 2008 to…
Nuovi dati biologici e geonemici su Lehmannia melitensis (Lessona & Pollonera, 1882) e Ambigolimax valentianus (A. Férussac, 1823) (Gastropoda: Limac…
2018
Nuovi dati biologici e geonemici sono riportati per Lehmannia melitensis (Lessona & Pollonera, 1882) e Ambigolimax valentianus (A. Férussac, 1823). In particolare, vengono fornite nuove località siciliane di L. melitensis mentre A. valentianus viene segnalato per la prima volta nelle isole italiane di Sardegna, Sicilia e Pantelleria e nell’isola maltese di Gozo. Le due specie, a volte simili nella morfologia esterna, si distinguono con certezza solo attraverso l’esame degli organi genitali. New records from Sicily are provided for Lehmannia melitensis (Lessona & Pollonera, 1882). Ambigolimax valentianus (A. Férussac, 1823) is recorded for the first time from the italian islands of S…
Empirical estimates of the radiative impact of an unusually extreme dust and wildfire episode on the performance of a photovoltaic plant in Western M…
2019
Abstract We have estimated the radiative impact produced by an unusually extreme dust and wildfire episode on the performance of a photovoltaic (PV) plant. The dust and wildfire events were mostly active on 26–28 and 29–30 June 2012, respectively. We took advantage of the consecutiveness of both events to separate and derive empirically the radiative effect of dust and smoke aerosols. With this purpose, we employed measurements of aerosol load, radiation and PV power output from a collocated atmospheric station and PV plant located at Burjassot (Valencia, Spain). The empirical estimates were obtained by direct comparison with a summer background day, happened right before the two consecutiv…
“Splendid Isolation”: embracing islandness in a global pandemic
2022
Islandness is often considered to be a disadvantage. However, it has helped the residents of islands to delay, deter, and, in some cases, totally insulate themselves from COVID-19. While islanders have been quick to lock themselves down, this has had a tremendous impact on their connectivity and on tourism, which in many cases is their major economic sector. Yet, the association of islands with being safe, “COVID-19 free” zones has helped these spaces to be among the first destinations to restart the tourism economy once travel restrictions were lifted. After several weeks of lockdown, and with the COVID-19 threat still looming, social distancing remained the norm. Travellers we…
NEW RECORDS OF SPRINGTAILS (COLLEMBOLA) FROM SICILY, ITALY
2022
Along with some studies on soil fauna in various Sicilian sites, both agricultural lands and typical Mediterranean habitats, particular attention was paid to the Collembolan. Specific identification allowed to assess the occurrence in Sicily of 39 species not previously recorded, belonging to 10 families: Hypogastruridae (six species), Brachystomellidae (one species), Neanuridae (five species), Onychiuridae (three species), Tullbergiidae (seven species), Isotomidae (nine species), Entomobryidae (three species), Cyphoderidae (one species), Dicyrtomidae (one species), and Katiannidae (one species). Of these 39 species, 21 are new also for Italy. Furthermore, this is the first record of the ge…
Role of rock fragment cover on runoff generation and sediment yield in tilled vineyards
2017
The soil in conventional Mediterranean vineyards is an active and non-sustainable source of sediment and water. Lack of vegetation cover, small soil organic matter content and intense ploughing result in large rates of erosion in a millennia-old tillage system. There is a need for soil conservation strategies that enable sustainability of wine and grape production; therefore, it is essential to measure the rates and to investigate the processes and factors of soil erosion. This study evaluated factors that can reduce soil losses in traditional Mediterranean vineyards. The investigation was carried out with 96 rainfall simulation experiments at the pedon scale (0.24 m2) to measure soil detac…
Changes in soil microbial community structure influenced by agricultural management practices in a mediterranean agro-ecosystem.
2013
Agricultural practices have proven to be unsuitable in many cases, causing considerable reductions in soil quality. Land management practices can provide solutions to this problem and contribute to get a sustainable agriculture model. The main objective of this work was to assess the effect of different agricultural management practices on soil microbial community structure (evaluated as abundance of phospholipid fatty acids, PLFA). Five different treatments were selected, based on the most common practices used by farmers in the study area (eastern Spain): residual herbicides, tillage, tillage with oats and oats straw mulching; these agricultural practices were evaluated against an abandon…
Soil macrofauna and organic matter in irrigated orchards under Mediterranean climate
2017
Soil fauna abundance and diversity and organic matter content are key indicators for the rate of soil degradation in Mediterranean-type ecosystems. The soil macrofauna populations were examined in three orange (Citrus sinensis) orchards and one persimmon (Diospyros kaki) orchard, with the same soil type and different management systems, to establish whether organic management benefits soil fauna and soil quality and what is the effect of flood irrigation. Vegetation cover, soil organic matter, bulk density and moisture were measured at each experimental site within the Canyoles watershed in Eastern Spain in summer of 2015. Earthworm abundance was highest at the organic orchard with flood ir…
