Multiple origins of methane in fluids circulating in the Othrys ophiolite, central Greece
2018
The complex geology of Greece includes two important parallel running ophiolitic belts. The Othrys Massif in central Greece belongs to westernmost of them. In and around this wide ophiolite outcrop, some cold hyperalkaline and some hypothermal (T < 40°C) alkaline springs are present. Thirty water samples were collected at 17 different sites and both bubbling and dissolved gases were analysed for their chemical (He, Ne, H2, O2, N2, CH4, C2H6, CO2 and H2S) and isotope (He, δ13C-CO2, δ 13C-CH4, δ 2H-CH4) composition. All samples except one have H2S contents below detection limit (10 μmol/mol), whilst H2 (from <2 to 2500 μmol/mol), CO2 (up to 26,000 but generally below 1000 μmol/mol) and …

Drāmas paņēmieni angļu valodas runāšanas trauksmes mazināšanai 6. klasē
2016
Lielākā daļa cilvēku, kuri mācās angļu valodu kā svešvalodu, saskaras ar angļu valodas runāšanas trauksmi. Tā negatīvi ietekmē gan skolēnu sniegumu, gan attieksmi. Pētījums tika izstrādāts ar mērķi pārbaudīt, kā drāmas paņēmieni samazināja skolēnu angļu valodas runāšanas trauksmi 6.klasē. Angļu valodas stundās 6.klasē tika izmantotas dažādas drāmas aktivitātes. Darbā tika lietotas tādas datu vākšanas metodes kā diagnosticējošs tests (pirms un pēc drāmas paņēmienu ieviešanas), intervija, novērošana un atgriezeniskā saite. Diagnosticējošā testa rezultāti norādīja, ka skolēni saskārās ar angļu valodas runāšanas trauksmes pazīmēm. Drāmas paņēmienu izmantojums palielināja skolēnu aktivitāti angļ…
Valutare la qualità energetico-ambientale nell’edilizia
2013
The building sector is one of the most important in terms of wealth and employment, but it also involves significant resource consumption and environmental impacts. In particular, it affects the energy balance and the greenhouse gas emissions in Europe. It is responsible for 50-60% of the natural resource consumption and for 40% of the total energy consumption in Europe, and this percentage will increase without strategies and actions aimed at enhancing the use of renewable energy resources. Therefore, the reduction of resource consumption and the minimization of environmental impacts have become in recent years the main goals in the design and construction of sustainable buildings (eco-des…
Ecological and economic indicators for the evaluation of almond (Prunus dulcis l.) orchard renewal in sicily
2020
Globally, almond production is experiencing a growing trend thanks to a strong interest in the health, gastronomic, and industrial properties that are linked to the fruits and their derivatives. After a constant and marked decline in the second half of the last century, the Mediterranean Basin is thoroughly reassessing this crop, which provides significant results with a modern orchard management. The opportunity determined by the transition from traditional to modern systems have increased the interest in evaluating the different environmental impacts of the two cultivation models that still coexist today. In this work, through the application of the Life Cycle Assessment (LCA) and an econ…
Analysis of the Sponge [Porifera] Gene Repertoire: Implications for the Evolution of the Metazoan Body Plan
2003
Sponges [phylum Porifera] form the basis of the metazoan kingdom and represent the evolutionary earliest phylum still extant. Hence, as living fossils, they are the taxon closest related to the hypothetical ancestor of all Metazoa, the Urmetazoa. Until recently, it was still unclear whether sponges are provided with a defined body plan. Only after the cloning, expression and functional studies of characteristic metazoan genes, could it be demonstrated that these animals comprise the structural elements which allow the sponge cells to organize themselves according to a body plan. Adhesion molecules involved in cell—cell and cell—matrix interactions have been identified. Among the cell—cell a…
