RESPONSABILITÉ EST PLANIFICATION. OEdipe planificateur de la ville du présent.
2016
Il contributo analizza e individua scenari di sviluppo per una condizione particolarmente sensibile quale quella in cui i grandi valori del patrimonio culturale e paesaggistico si intrecciano con le richiesta di trasformazione. La relazione, quindi, tra la pianificazione territoriale e una visione strategicamente orientata per la valutazione delle risorse ambientali viene individuata come una possibile soluzione alla crescita senza controllo e come risolutore della condizione di conflitto determinato dalla assenza di relazioni tra tutelato e non tutelato. Le document analyse et identifie les scénarios de développement pour une condition particulièrement sensible: les grandes valeurs du pays…
Physiological,anatomical and biomass partitioning responses to ozone in the Mediterranean endemic plant Lamottea dianae
2011
Ozone effects on the perennial forb Lamottea dianae were studied in an open-top chamber experiment. Ozone was found to induce reductions in CO 2 assimilation and water use efficiency in the leaves of this species. These reductions were mainly related to a decline in the in vivo CO 2 fixation capacity of Rubisco (V c,max), rather than to stomatal limitations or photoinhibitory damage (F v:F m). In addition to chloroplast degeneration, other observed effects were callose accumulation, formation of pectinaceous wart-like cell wall exudates and phloem alterations. Moreover, ozone exposure significantly reduced root dry biomass. The possible relevance of these adverse effects for Mediterranean f…
La tutela del contraente debole nella platform economy
2018
Negli ultimi anni si è affermato un nuovo modello di attività produttiva nel quale piattaforme digitali mettono in contatto gruppi interdipendenti di agenti economici per facilitare lo scambio di beni e l’erogazione di servizi. Dinanzi a questa trasformazione nell’organizzazione d’impresa, nel coordinamento del lavoro e nella struttura dei mercati, il diffuso appello a stabilire un “terreno di gioco neutrale” diviene la premessa per proporre la deregolamentazione di interi comparti economici valorizzando la capacità di autogoverno delle piattaforme. Mentre le reazioni a queste proposte sono confinate quasi esclusivamente alla questione del lavoro, è mancata finora un’analisi più generale de…
El ‘relato maravilloso’ como expresión mítica de la presencia o ausencia divina
2020
El relato maravilloso constituye un recurso eficaz que el mito proporciona a las sociedades antiguas para articular y dar explicación a la relación del hombre con la naturaleza y a la presencia o ausencia de la protección divina. The ‘wonderful story ’constitutes an effective resource that myth provides to ancient societies to articulate and explain man’s relationship with nature and the presence or absence of divine protection.
Group model building: a collaborative modelling methodology applied to critical infrastructure protection
2012
Large crises management, affecting CIs needs multidisciplinary knowledge including technical, economical, social, political, legal and managerial knowledge. Being these crises international a huge variety of agents is involved in their response. This situation concludes in a set of stakeholders who only have fragmented knowledge. In the presence of dispersed and incomplete knowledge, and of fragmented and disrupted crisis management, the collaborative approach group model building (GMB), where modelling experts unify fragmented, tacit knowledge from domain experts, is a valuable option. However, GMB has been little used in CIP. We have done so in the context a European project on crisis man…
Single and Coupled Electrochemical Processes and Reactors for the Abatement of Organic Water Pollutants: A Critical Review.
2015
Traditional physicochemical and biological techniques, as well as advanced oxidation processes (AOPs), are often inadequate, ineffective, or expensive for industrial water reclamation. Within this context, the electrochemical technologies have found a niche where they can become dominant in the near future, especially for the abatement of biorefractory substances. In this critical review, some of the most promising electrochemical tools for the treatment of wastewater contaminated by organic pollutants are discussed in detail with the following goals: (1) to present the fundamental aspects of the selected processes; (2) to discuss the effect of both the main operating parameters and the rea…
Cathodic abatement of Cr(VI) in water by microbial reverse-electrodialysis cells
2015
Abstract For the first time a microbial reverse electrodialysis cell (MRC) was used for the treatment of water contaminated by Cr(VI). It has been recently shown that both inorganic and organic pollutants can be removed by reverse electrodialysis processes (RED) using water with different salinity without the supply of electric energy. However, a high number of membrane pairs is usually necessary for the treatment of wastewater by RED. Here, it was showed that a lower number of membranes can be used by the utilization of a MRC (i.e., a RED cell with a biotic anode) for such purposes. Indeed, the abatement of Cr(VI), chosen as model pollutant, was successfully achieved by cathodic reduction …
THE IMPACT OF WARFARE ON THE SOIL ENVIRONMENT
2013
Abstract One of the most dramatic ways humans can affect soil properties is through the performance of military activities. Warfare-induced disturbances to soil are basically of three types – physical, chemical, and biological – and are aimed at causing direct problems to enemies or, more often, are indirect, undesired ramifications. Physical disturbances to soil include sealing due to building of defensive infrastructures, excavation of trenches or tunnels, compaction by traffic of machinery and troops, or cratering by bombs. Chemical disturbances consist of the input of pollutants such as oil, heavy metals, nitroaromatic explosives, organophosphorus nerve agents, dioxins from herbicides, …
Economic analysis and energy valorisation of by-products of the wine supply chain: the case of the 'Mamertino wine PDO'
2018
The paper reports the analysis of biomass derived from maintenance of a vineyard, to assess its potential as an alternative energy source, instead of the usual disposal of the wine supply chainâs residuals. The site studied is within the province of Messina, Sicily, in the area of Mamertino wine PDO, a wine of superior quality. The analysis suggests that use of this kind of biomass may allow a fossil fuel such as liquefied petroleum gas (LPG) to be replaced by a wine wood chip biomass boiler, thus meeting economic and environmental criteria by reason of recycling for sustainability.
Origin of atmospheric lead in Johannesburg, South Africa
2006
International audience; The origin of lead in the atmosphere of Johannesburg, South Africa was investigated on the basis of elemental and lead isotopic analyses of coals, mine dumps, gasoline, and about 30 epiphytic lichen samples. Lead predominantly comes from automotive exhausts in urban and suburban areas, as leaded antiknock additives were still in use in South Africa at the time of the study. Although dust emissions from the numerous mine-tailing dumps were expected to contribute significantly to the heavy metal budget, the southern townships that are surrounded by the dumps (such as Soweto and other historically Black residential areas) do not appear to be more than partially influenc…
