Mutamento del giudice e rinnovazione della prova: la Corte costituzionale esorbita dai confini accusatori
2020
The “Judge of the laws” delivers to the Parliament punctuals directives to give concreteness to the reasonable duration of the trial. What is at stake is the right to renew the evidence in the event of a change of the judge, which is drastically reduced to prevent it from being used merely for dilatory purposes. The Author criticizes the decision in question, fearing a dangerous drift: the renewal only of the “useful” evidence.
The risk management in the international contracts of marine renewable energy : focus on offshore wind farms
2022
At a time when climate change is becoming the main concern, the renewable energy sector is developing extremely rapidly. In order to add other sources to the existing ones and to increase electricity production while ensuring its stability, the sea has quickly been considered as an attractive alternative. However, the creation of a new industry is a major challenge and marine renewable energy projects are very expensive and risky. The concept of risk was created specifically regarding the management of human activities at sea. The example of offshore wind energy allows us to go back to the origins of the notion of risk by considering it from the point of view of the company, and to analyse …
Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
Relevance of Oxygen Concentration in Stem Cell Culture for Regenerative Medicine
2019
The key hallmark of stem cells is their ability to self-renew while keeping a differentiation potential. Intrinsic and extrinsic cell factors may contribute to a decline in these stem cell properties, and this is of the most importance when culturing them. One of these factors is oxygen concentration, which has been closely linked to the maintenance of stemness. The widely used environmental 21% O2 concentration represents a hyperoxic non-physiological condition, which can impair stem cell behaviour by many mechanisms. The goal of this review is to understand these mechanisms underlying the oxygen signalling pathways and their negatively-associated consequences. This may provide a rationale…
Distribution and characteristics of Listeria monocytogenes isolates from surface waters of the South Nation River Watershed, Ontario, Canada
2007
ABSTRACT Listeria monocytogenes is a facultative intracellular pathogen thought to be widely distributed in the environment. We investigated the prevalence and characteristics of L. monocytogenes isolates from surface waters derived from catchments within the South Nation River watershed (Ontario, Canada). This watershed is dominated by urban and rural development, livestock and crop production, and wildlife habitats. From June to November 2005, a total of 314 surface water samples were collected biweekly from 22 discrete sampling sites characterized by various upstream land uses. Presumptive Listeria spp. were isolated using a selective enrichment and isolation procedure, and 75 L. monocyt…
Estimation of Role of Sicilian Region on Production of Quality Wines. A Comparison between the Best Sicilian and Italian Wines by Using Influential W…
2016
Abstract Sicilian region (Southern Italy) has always been the larger Italian wine producer, because of their terroir (i.e. climate, soil and cultivar) and the extension of the vineyard area. For a long time, in the past, Sicilian vineyards produced only wine for blending or for bulk wine consumption. However, the quality of wine production in the Sicilian region has raised significantly over the past years, due to numerous factors, including, primarily, the development of manufacturing techniques, the major business investments of wineries, and the better legislation for protection of quality wines. These factors, combined with producers' targeted marketing strategies and actions, have grea…
SOFIA: a decision support System for the Optimization of the biomass supply chain and Forest Integrated management in protected areas
2019
A decision support System for the Optimization of the biomass supply chain and Forest Integrated Management in protected areas (SOFIA) is presented. All functionalities have been developed in Python language embedded in the open-source QGIS 3.6 software. Two models were implemented with an approach and methodology based on free and open source software (QGIS, GRASS, SAGA, GDAL). The main aim of SOFIA is to support the Madonie Regional Natural Park authority and forest managers in decision-making processes to assess the costs and benefits in the energy production from residual agro-forestry biomass, as well as for determining the optimum plant size (and power) for energy and heat production …
Study of energetic properties of different tree organs in six Olea europaea L. cultivars
2021
AbstractPruning is an important horticultural practice for the management of olive orchards (Olea europaea L.) that generates a considerable amount of residues every year. Olive orchards are increasingly expanding beyond the Mediterranean Basin to new growing Countries (Australia, California, Argentina, Chile and Uruguay) and this will certainly lead to larger availability of pruning material. Currently, the interest in use of olive tree pruning residues for energy purposes is increasing but unfortunately, the information on the differences among organs of the tree, in terms of calorific value and ash content, is scarce. Another unknown aspect is the effect of cultivar vigour on dry matter …
Enhanced Sewage Sludge Drying with a Modified Solar Greenhouse
2022
This work reports the results obtained with an innovative configuration of a closed-static solar greenhouse for sludge drying. The novelty of the solar greenhouse configuration consisted in using a forced ventilation system to provide hot air for sludge drying and the utilization of solar irradiation for energy supply. Wet sewage sludge (97% humidity) was successfully dried up to a residual humidity close to 5% after 25 days during wintertime. The increase of the airflow rate supplied under the sludge bed improved the sludge drying rate. Moreover, the fraction of volatile suspended solids decreased from 70% to 41% after 13 days, indicating that air supply promoted the simultaneous stabiliza…
Reconstruir la ciudad sobre la ciudad. El Projet Euroméditerranée en Marsella
2014
At the end of XX century, the city of Marseille suffered a severe crisis caused by decline of industrial and port activities, on which was based city's economy. Despite crisis, Marseille has reacted creating new economic and urban strategies. In particular, the article analyses two phases of Euroméditerranée redevelopment project, which has been promoted by the Etablissement Public d'Aménagement Méditerranée. The aim of this ambitious project is to set Marseille again in the core of its region and the whole Mediterranean area. Euroméditerranée I project (1995-2015) deal with the requalification of waterfront and abandoned industrial heritage and the enhancement of historic city centre. More…
