Energetic Sustainability Using Renewable Energies in the Mediterranean Sea
2016
The paper is focused on the analysis of the electrical energy sector in the Maltese islands, focusing on the employment of Renewable Energies in order to increase its energy independence. The main renewable source here proposed is wave energy: thanks to its strategic position, Malta will be able to generate electrical energy through the use of an innovative type of Wave Energy Converter (WEC) based on the prototype of linear generator designed and developed by the University of Palermo. This new technology will be able to cut down the electrical energy production from traditional power plants and, consequently, the greenhouse gas emissions (GHG). Wave energy source and off-shore photovoltai…
Sustainability of the Renewable Energy Extraction Close to the Mediterranean Islands
2017
The aim of this work is to explore the possibility of transitioning a fuel powered island to a renewable powered one. This transition is analyzed for the real MV/LV distribution system of the island of Pantelleria, in the Mediterranean Sea. Particularly, this work is focused on a renewable source nowadays totally unused: wave energy. Thanks to the innovative generator prototype designed by Department of Energy of University of Palermo (Italy), wave energy is able to represent a primary source for the production of electric energy in the Mediterranean islands. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in di…
Renewable energy sources to fulfill the global energy needs of a country: The case study of Malta in Mediterranean Sea
2016
The paper shows the advantages using different energy resources for the islands of Malta. Moreover, this work is focused on the analysis of the wave energy potential along Malta's coasts. This important resource can be exploited to produce electrical energy using an innovative Point Absorber based on a new generator prototype realized by University of Palermo. The use of renewable source will reduce greenhouses emissions and increase the energy independence of Malta. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in different technical fields that show a good replicability [1]-[7].
Near zero energy island with sea wave energy: The case study of Pantelleria in Mediterranean Sea
2016
In this paper the authors present a study of the transition of an energy generation system for a real MV/LV distribution system from one that is "fuel-based" to a "renewables-based" system in particular from sea wave energy, using the data acquired from an innovative generator prototype realized by University of Palermo. The study is carried out for a real islanded network located in the Island of Pantelleria (Mediterranean Sea). The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in different technical fields that show a good replicability [1]-[7].
Greening island: Renewable energies mix to satisfy electrical needs of Pantelleria in Mediterranean sea
2016
In this article the authors analyze the renewable mix in order to satisfy the energy needs of a real island in the Mediterranean sea, Pantelleria, which represents an optimal starting point to increase the production of electrical energy from renewable sources in minor islands. In this text are exposed different alternative sources, such as solar, wind and wave energy. Moreover, it is exposed a project of an innovative conversion device proposed by Department of Energy of University of Palermo, compared to a different one proposed by Politecnico di Torino. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in diffe…
Carbamazepine exposure in the sea anemones Anemonia sulcata and Actinia equina: Metabolite identification and physiological responses
2020
Trabajo presentado en el 11º Congreso Ibérico, 8º Iberoamericano de Contaminación y Toxicología (CICTA 2018) celebrado en la Escuela Técnica Superior de Ingeniería de Montes, Forestal y del Medio Natural, Madrid del 11 al 13 de julio de 2018
Variation in the stable isotope trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766) from two Mediterranean sites: insights from a g…
2022
A direct consequence of sea warming is the shift in the distribution range of thermo-tolerant species that have the potential to determine novel inter-specific interactions, ultimately altering food web structures and ecosystem processes. In this study, we investigated the trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766), a pelagic predator that has recently expanded its distribution in the Mediterranean basin and for which scant information is available on its functional role in recently-colonised areas. Nitrogen and carbon stable isotopes were determined in muscle tissues of bluefish specimens collected in south-east Italy in the Gulf of Taranto (NW Ionian Sea) and in…
Metagenomics Reveals Planktonic Bacterial Community Shifts across a Natural CO2 Gradient in the Mediterranean Sea
2015
ABSTRACT Bacterial communities at a CO 2 vent (pH 6.7) were compared with those at control (pH 8.0) and transition sites (pH 7.6) using 16S rRNA metagenomics. Firmicutes and unclassified bacteria dominated across all sites, Proteobacteria , especially Gammaproteobacteria , declined, and Epsilonproteobacteria increased in the vent with an increase in Bacteroidetes at both the vent and transition sites.
Estimation of Daily Solar Radiation from Measured Air Temperature Extremes in the Mid-Mediterranean Area
2012
AbstractDaily solar radiation Rs at ground level is a necessary input variable required for the evaluation of evapotranspiration and crop growth, development, and yield-simulation models. Nevertheless, it is measured in few weather stations and at many locations it is not observed; also, available Rs temporal series are generally no longer than a few years. A valid surrogate of Rs measurement is the diurnal air-temperature range (ΔT); indeed, ΔT is inversely proportional to cloudiness and therefore could be a good indicator of atmospheric transmittance. As opposed to Rs, daily maximum and minimum air temperatures are measured at many locations and their observations in developed countries b…
A taxonomic revision helps to clarify differences between the Atlantic invasive
2017
Abstract Ptilohyale explorator (formerly Parhyale explorator), described by Arresti (1989), can be considered to be a synonym of west-Atlantic Ptilohyale littoralis (Stimpson, 1853), based on morphological observations of paratypes and specimens recently collected in the type locality of Ptilohyale explorator. The first collections of Ptilohyale littoralis, from the eastern Atlantic were from the port of Rotterdam (The Netherlands) in 2009 and later in Wimereux, Opal Coast (France) in 2014; however, the synonymy of Ptilohyale explorator with Ptilohyale littoralis backdates to the first European record of Ptilohyale littoralis in 1985 at La Vigne, Bay of Arcachon (France). This indicates tha…
