Diffusion of innovative agricultural production systems for sustainable development of small islands: A methodological approach based on the science …
1992
In order to develop small islands, not only must a vital agricultural system be maintained, but the range of opportunities for tourism must be increased with respect to both the seaside and the environmental features of the rural landscape. As an alternative to the traditional and economically declining ones, many innovative production processes can be identified, but their success depends on their interaction with the physical, biological, economic and social environment. In order to identify the main nodes and the most critical interactions, so as to increase the probability of success of a new productive process, a methodological approach based on the science of complexity is proposed fo…
Editorial: Sustainable development of energy, Water and Environment Systems
2020
In 2018 the Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES) was held in three different locations and periods, so as to offer to the scientific community working in the field several opportunities to share and discuss new ideas and disseminate results of research activities. The 1st Latin American SDEWES Conference was held in Rio de Janeiro (Brasil) in January 28–31 and attracted 180 scientists from 35 countries, with a high number of contributions mainly from Southern American and European academics and professionals, who reciprocally enriched about emerging issues in the field of sustainable development in these continents. Also, the participants a…
PROPOSALS FOR ENVIRONMENTAL NOISE MANAGEMENT BOOST AT A NATIONAL LEVEL IN THE EUROPEAN UNION MEMBER STATES
2017
Environmental noise is currently becoming one of the most dominant types of environmental pollution. The effects of environmental noise closely correlate with quality of life especially regarding the physical and psychological health of inhabitants, social and economic costs, and thus also impacting the sustainable development of a country. Environmental noise management, therefore, is one of the most necessary and exigent aspects of environmental pollution management governance. The management of noise need to be developed in a comprehensive, integrative and cross-sectorial way, and appropriate methods and approaches for the management of overall noise impacts need to be found to deal with…
Sustainable and cost-efficient energy supply and utilisation through innovative concepts and technologies at regional, urban and single-user scales
2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
Direct assessment of the sensitivity drift of SQM sensors installed outdoors
2021
Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollution mitigation measures. Detecting the underlying artificial brightness trend is a challenging task, since the typical night sky brightness signal shows a large variability with characteristic time scales ranging from seconds to years. In order to effectively isolate the weak signature of the effect of interest, determining the potential long term drifts of the radiance sensing systems is crucial. If these drifts can be adequately characterized, the raw measurements could be easily corrected for them and transfor…
Du comptage ponctuel à l'affectation par simulation multi-agents : application à la circulation routière de la ville de Dijon
2014
A travers une démarche expérimentale de simulation de la circulation routière pour estimer les pollutions atmosphériques en milieu urbain, cette proposition questionne les opportunités qu'offre la simulation multi-agents pour intégrer des données d'observations du trafic routier au sein d'un système d'information géographique. Pour cela, la construction du modèle d'affectation s'est faite en deux étapes : une première, d'acquisition et de structuration des données de comptages et une seconde visant à interfacer ces données au sein d'une plateforme de simulation multi-agents pour en reproduire la variabilité intra journalière et la fréquentation routière.
Identification and dose dependency of ibuprofen biliary metabolites in rainbow trout
2012
Abstract The biotransformation of the anti-inflammatory drug ibuprofen (IBF) was studied by exposing rainbow trout ( Oncorhynchus mykiss ) to IBF via intraperitoneal (i.p.) injection, and via water at four (0.17, 1.9, 13 and 145 μg L −1 ) exposure levels for 4 d. Following exposure, the bile was collected and analyzed by LC–MS/MS methods. The identification of the formed metabolites in i.p. injected fish bile was based on the exact mass determinations by a time-of-flight mass analyzer (Q–TOF–MS) and on the studies of fragments and fragmentation patterns of precursor ions by ion trap mass analyzer (IT-MS). In addition to unmetabolized IBF, several phase I and phase II metabolites were found …
Biomonitoring with cryptogams near the power station of la Robla (Leon, Spain)
2007
The present monitoring study was undertaken to analyze the impact of atmospheric pollution on the lichens found near a power station in northern Spain. Data from 565 releves gathered on 113 sites were analyzed. In areas near the power station the lichen species belong to the Xanthorion community. In areas away from the power station and that are not under the influence of dominant winds, the lichenic diversity increases and the species present belong to the Parmelion community. In intermediate areas between the two, there is a great increase in lichen diversity, in these areas there is a replacement of the species that typically belong to the Xanthorion community, by species typical of the …
Modelling the Interaction between Air Pollutant Emissions and Their Key Sources in Poland
2021
The main purpose of this study is to investigate the relationships between key sources of air pollutant emissions (sources of energy production, factories which are particularly harmful to the environment, the fleets of cars, environmental protection expenditure) and the main environmental air pollution (SO2, NOx, CO and PM) in Poland. Models based on MLP neural networks were used as predictive models. Global sensitivity analysis was used to demonstrate the significant impact of individual network input variables on the output variable. To verify the effectiveness of the models created, the actual data were compared with the data obtained through modelling. Projected courses of changes in t…
A new tool to process forecast meteorological data for atmospheric pollution dispersion simulations of accident scenarios: A Sicily-based case study
2021
Emergency response plans to mitigate the severity of the accidental release of hazardous compounds in the air have become a primary concern in view of the many adverse events occurred over the years in high-risk plants. To do this, an accurate estimate of forecast meteorological data to be used in dispersion models can be very useful to respond in advance to emergency situations. In this field, FORCALM is a new tool developed to elaborate European Centre for Medium-Range Weather Forecasts data on a 3D computational domain with a high-resolution grid. FORCALM data can be used to perform predictive simulations of impacts on local and regional levels by using CALPUFF modelling system. A case s…
