INDUCED MODIFICATION OF FLEXURAL TOUGHNESS OF BIO-LIME BASED MORTARS BY ADDITION OF GIANT REED FIBERS
2019
Fibers are often used as reinforcement of brittle materials, like mortars, in order to modify their mechanical behavior; particularly the modification in post-cracking toughness, induced by low elasticity modulus fibers in the artificial stone material, is the main goal in natural fibers mortar manufacturing. In this work Arundo donax L. fibers are used to reinforce lime mortars according to the characteristics of this plant, very commonly available and with high mechanical properties, similar to bamboo, traditionally used in buildings in Spain. Influence of fibers’ length and weight ratio is studied. Particularly, three different fibers’ lengths, 4, 8 and 12 centimeters, and three weight r…
Self-assembly of catalytically-active supramolecular coordination compounds within metal-organic frameworks
2019
[EN] Supramolecular coordination compounds (SCCs) represent the power of coordination chemistry methodologies to self-assemble discrete architectures with targeted properties. SCCs are generally synthesized in solution, with isolated fully coordinated metal atoms as structural nodes, thus severely limited as metal-based catalysts. Metal-organic frameworks (MOFs) show unique features to act as chemical nanoreactors for the in situ synthesis and stabilization of otherwise not accessible functional species. Here, we present the self-assembly of Pd-II SCCs within the confined space of a pre-formed MOF (SCCs@MOF) and its post-assembly metalation to give a Pd-II-Au-III supra molecular assembly, c…

Characterization of a small Mediterranean island end-users’ electricity consumption: The case of Lampedusa
2017
Abstract The paper presents the results of a study carried out on Lampedusa Island (Italy) and based on the survey of electricity consumption data. The main outcomes of the study are: • the characterization of the energy demand of private houses and hotels in Italian small islands with significant touristic flows during the summer period; • the identification of inefficient use of the electric loads; • the construction of aggregated load profiles for clusters of homogeneous domestic end-user to be used for implementing Demand Response strategies. The study shows how electricity consumption in Mediterranean small islands are very high with respect to the national average and lays the basis f…
Germplasm evaluation to obtain inulin with high degree of polymerization in Mediterranean environment
2020
Long-chain length (DP) inulin-type fructans show pronounced beneficial effects to colon microbiota. In the past, cardoon roots for inulin production to fortify spaghetti gave very good results, but their harvest requires high costs. The aim of the work was to evaluate different types of inulin, extracted from cardoon roots and buds, topinambur tubers and chicory roots local populations in order to identify crops more suitable for high DP inulin production in Mediterranean environment. The inulin amount resulted in 115 (chicory), 390 (cardoon) and 550 g kg−1 of d.m. (topinambur). Both in cardoon roots and in topinambur tubers the DP was very high. With the aim to produce a functional food, s…
Scale effects on plot runoff and soil erosion in a mediterranean environment
2017
Explaining scale effects for runoff and erosion improves our understanding of hydrological and erosion processes. In this investigation, plot-scale effects on event runoff per unit area, Qe, sediment concentration, Ce, and soil loss per unit area, SLe, were checked at the Sparacia (Italy) site. Similar information on the scale effects was obtained with different dependent variables, i.e., individual values of Qe, Ce, and SLe for each plot or the mean of their replicated values, and scale indicators, i.e., plot length, l, or plot area, A. The most common result, occurring for 57 to 62% of the events depending on the considered variable, was the lack of any scale effect. When scale effects we…
Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sici…
2014
Ethnopharmacological relevance: This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It specifies contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. Aim of the study: The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of…
Dune systems' characterization and evolution in the andalusia mediterranean coast (Spain)
2020
This paper deals with the characterization and evolution of dune systems along the Mediterranean coast of Andalusia, in the South of Spain, a first step to assess their relevant value in coastal flood protection and in the determination of sound management strategies to protect such valuable ecological systems. Different dune types were mapped as well as dune toe position and fragmentation, which favors dune sensitivity to storms&rsquo
La complessità del paesaggio agrario del “giardino mediterraneo” a partire dalla tavola di Alesa
2014
The Mediterranean is characterized by landscapes as result from long and complex historical processes in a varied environment. An identification and clarification of the role of the “Mediterranean Garden” (MG) in the Traditional Mediterranean Landscape (TML) is necessary. The MG is often associated with numerous different agricultural landscapes, due to the long historical process that has led to their identification. This paper identifies the characteristics of the MG’s landscape, starting from a historical overview of Sicily. What emerges is the structural, compositional and functional character of these traditional landscapes and systems, which is complex, multipurpose and often with mix…
Meristic character analysis and skeletal anomalies during growth in reared sharpsnout seabream
2000
Sharpsnout seabream (Diplodus puntazzo) is a species currently reared in Mediterranean fish farms. In order to detect the main types of body deformation in sharpsnout seabream. 120 specimens (60 juveniles and 60 adults) taken from a Mediterranean hatchery were examined. In juveniles and adults non-significant differences were found in the number of vertebrae, dorsal spines and pectoral fin rays. Moreover, the number of anomalies varied with age. The juveniles presented 28 types of anomaly, the adults 25. The most important anomalies for juveniles (in terms of frequency of occurrence) were anomalous neural arch or spine (47%), anomalous hemal arch or spine (43%), fusion of hypurals (67%) and…
