Fen peat in environmentally friendly technologies
2018
Abstract Using peat as an energy source is currently incompatible with Environmental Policy Strategy of Latvia and 2030 Climate and Energy Package of European Union. The European Commission is looking at cost-efficient ways to make European economy more climate-friendly and less energy consuming. Although, fen peat alongside raised bog peat is categorized as fossil fuel, it is not traditionally used as fuel or growth substrate or for any other significant purposes in reasonable amounts. Large areas of fens are neglected where fen peat is slowly mineralizing and emitting greenhouse gases, such as carbon dioxide and methane, that are ones of the main triggers for the Climate Change. Thus, to …
Active moss monitoring allows to identify and track distribution of metal(loid)s emitted from fumaroles on Vulcano Island, Italy
2014
Abstract Volatile metal(loid)s are known to be emitted from volcanoes worldwide. We tested the suitability of active moss monitoring for tracking volatile metal(loid)s released from the fumarolic field on Vulcano Island, Italy, and differentiated fumaroles from other sources of gaseous and particulate trace elements such as sea spray and soil. Metal(loid) accumulation on the mosses per day did depend neither on the state of the exposed moss (dead or living) nor exposure time (3, 6, or 9 weeks). After collection, mosses were digested with either HNO3/H2O2 or deionized water and analyzed by ICP-MS. While for most elements both extraction methods yielded similar concentrations, higher concentr…
Elevation of the last interglacial highstand in Sicily (Italy): A benchmark of coastal tectonics
2006
Well-preserved MIS 5.5 terraces in Sicily are identified primarily by the index fossil Strombus bubonius, and dated by amino acid racemization (AAR), electron spin resonance (ESR), Uranium/Thorium (U/Th) and thermo luminescence (TL) methods. This review of published data and new results for the island of Sicily and neighbouring small islands of Egadi, Ustica and Lampedusa identifies areas of rapid uplift in the east (up to +175 m, elevation above sea level), slower uplift in the north (+29 m), and relative stability in the northwest (+2/+18 m). In contrast, about 250 km of the southern coastline of Sicily does not appear to contain MIS 5.5 outcrops. In eastern Sicily, correlation of MIS 5.5…
A Sustainable Energy Mix for the Aeolian Islands
2018
The paper examines the current status of the electrical energy production in the Aeolian Islands, an Italian archipelago, composed by small island North of Sicily. Instead the availability of renewable energy sources, like wind, solar, geothermal and sea wave, these islands produce electrical energy using almost entirely fossil fuels. Starting from this initial condition, the paper proposes an energetic mix based on the available resources and focusing the attention on sea wave. An innovative device is presented in order to exploit this energy source.

Revision of Recent and fossil Mixtacandona Klie 1938 (Ostracoda, Candonidae) from Italy, with description of a new species
2017
Although studies on ostracods dwelling in inland subterranean habitats of Italy have increased in the last decades, highlighting a considerable taxonomic diversity, available information is still far from sufficient to understand phylogenetic and biogeographic relationships. Mixtacandona Klie 1938 is one of the most common and diverse genera of ostracods in subterranean waters. Of the 20 living recognized species in the genus, all stygobiontic and restricted to the Palearctic Region, four are known for the Italian peninsula and Sardinia, one of which exclusively as fossil. Several other Recent and fossil taxa attributable to Mixtacandona, but identified at supraspecific level, have been rep…
Concreções calcárias da formação Santana, bacia do Araripe: uma proposta de classificação.
2007
18 pages; The calcareous concretions of the Santana Formation have been known since 1800 thanks to the work of João da Silva Feijó (1800). Their study was promoted internationally by the report of von Spix and von Martius (1823-1831), and their richness in fossil fishes led Silva Santos to name them “ichthyoliths” in 1950. Here we propose a classification for the various types of calcareous concretions that occurred in the Santana Formation (Late Cretaceous, Araripe Basin). We consider their geographic distribution and we propose a terminological uniformization for the descriptions of that material. This will serve future statistical, geographical, geochemical and taphonomical studies that,…
Noyen-sur-Seine (Seine-et-Marne), Nord du Bois du Chêne, Caille-Boton, La Chapotte et Le Haut du Faÿ : phase 2 : rapport de diagnostic
2011
Ce diagnostic se situe sur la commune de Noyen-sur-Seine, sur une carrière d'exploitation de granulats. Il a permis la mise au jour de structures du Campaniforme au Nord-Est du site, de l'étape moyenne du Bronze final (culture Rhin-Suisse-France orientale) et du Hallsatt D2/3-La Tène A. Les structures de la culture RSFO sont en continuité avec celles mises au jour lors du diagnostic sur la parcelle adjacente (Samzun, 2009), et qui ont donné lieu à une fouille durant l'été 2010 (Nallier, à paraître). Les structures du Hallstatt sont apparues au Nord-ouest du décapage.
Jaulnes (Seine-et-Marne), "Les Graviers" : rapport de diagnostic
2010
Ce diagnostic a permis la mise au jour de structures du Néolithique récent/final dont une sépulture, ainsi que des monuments funéraires protohistoriques et des structures gallo-romaines.
