Enhancing Waste Governance through Dynamic Performance Management. An analysis of the Sicilian Waste System.
CoSAC, un projet pour la conception de stratégies durables de gestion des adventices dans un contexte de changement (climat, pratiques agricoles, bio…
2016
The CoSAC project associates partners from research and development in order to (1) quantify and understand, with experiments, the effects of novel agricultural practices on weeds and the functioning of the agroecosystem, (2) design tools that predict the effect of agricultural techniques et pedoclimate on weed flora, (3) use these tools to design sustainable weed management strategies and to evaluate their performances in contexts of changing agricultural practices, climate, biodiversity, (4) facilitate the adoption of these novel strategies by farmers. We will present the first results of the project, e.g. the effect on weeds of cover crops during fallow or associated to a cash crop, the …
Graduate Studies of Global Change at the University of Latvia
2010
In 2008 the University of Latvia (UL) completed an 18-month project of innovation – design, preparation and pilot-test of a 4-semester programme of trans-disciplinary graduate studies in “science, global change, and technologies for sustainable development” based on the experience the project team had acquired during 1997–2006 endorsing studies in “physics and technologies for sustainable development” and organizing two international conferences on “integrative approaches towards sustainability”. Within the project activities 25 members from faculties of natural sciences of the UL prepared and tested innovative courses of a 2 semester pilot programme comprising 4 modules, the audience being…
Impact of Ir modification on the durability of FeNC catalysts under start-up and shutdown cycle conditions
2022
A common problem associated with FeNC catalysts is their poor stability dominated by the carbon oxidation reaction (COR). In this work, the feasibility of stabilizing FeNC catalysts with small quantities of Ir was explored. With iridium being present, instead of COR the oxygen evolution reaction should be favored. The impact on structure and morphology was investigated by 57Fe Mössbauer spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy and transmission electron microscopy. The catalytic activity and durability for the oxygen reduction reaction was evaluated by rotating ring disc electrode experiments and accelerated stress tests mimicking the start-up and shutdown cycle (SS…
The plants of the future. : genome editing in biotechnology
2021
The evolution of life has led to the formation of complex systems where plants are essentials. Homo sapiens’ success is based on its ability to obtain food. In what remains of this century, the world population will increase by a quarter of the current total, reaching 10 billion people. This is itself a major challenge, amplified by the environmental conditions resulting from global change and the threat to sustainability derived from the use of the planet’s natural resources. Thus, we wonder if we will be able to respond to this challenge and, to that end, how the plants of the future should look. Recent advances in sequencing techniques allow us to identify genomes at a low cost, and geno…
Territorial Connection and Cohesion - The Case of Agrigento Inland Area
2014
The Europe 2020 strategy and the Horizon 2020 program can begin a real path about the role that the city will be able play for a new development. Usually, it is in the cities that are intensifying tangible and intangible social relations and, given that they focused almost 70% of the world population, it is clear that the city must begin to start any development scenario: the problems / opportunities related to the management of natural resources, energy to move. The culture is a «primary factor of urban creativity (...), the city's identity that has its roots the program schedule of history and extends its branches in the future» [4], awaiting a new model of development local self-sustaina…
Design and preparation of core-shell structured magnetic graphene oxide@MIL-101(Fe): Photocatalysis under shell to remove diazinon and atrazine pesti…
2020
Abstract A magnetically separable support with core-shell morphology comprising amine-functionalized Fe3O4 wrapped with graphene oxide (AFG) was successfully prepared and used to support MIL-101(Fe). The ternary AFG@MIL-101(Fe) composite was investigated as a photo-Fenton catalyst for the degradation of recalcitrant diazinon (DIZ) and atrazine (ATZ) pesticides. After 105 min visible light irradiation, the AFG@30MIL-101(Fe) photocatalyst achieved 100 ± 1% and 81 ± 1% photocatalytic degradation efficiency for DIZ and ATZ pollutants, respectively. The recorded data indicated superior photocatalytic ability of the nanocomposite as compared to AF@30MIL-101(Fe) and MIL-101(Fe) photocatalysts for …
Agents of change: Women in top management and corporate environmental performance
2020
International audience; We analyze the influence of gender diversity in top management on the environmental performance of French firms. Consistent with gender socialization theory, which posits that women are raised from childhood to be more nurturing and compassionate for others, we find that firms with more women in top management exhibit higher environmental performance. This result extends those already reported in the literature regarding the effect of gender diversity at board level. We also show that women in top management are associated with several key indicators such as development of eco‐friendly products and commitment to resource reduction. Furthermore, we find that the influ…
Energy harvesting by waste acid/base neutralization via bipolar membrane reverse electrodialysis
2020
Bipolar Membrane Reverse Electrodialysis (BMRED) can be used to produce electricity exploiting acid-base neutralization, thus representing a valuable route in reusing waste streams. The present work investigates the performance of a lab-scale BMRED module under several operating conditions. By feeding the stack with 1 M HCl and NaOH streams, a maximum power density of ~17 W m−2 was obtained at 100 A m−2 with a 10-triplet stack with a flow velocity of 1 cm s−1, while an energy density of ~10 kWh m−3 acid could be extracted by a complete neutralization. Parasitic currents along feed and drain manifolds significantly affected the performance of the stack when equipped with a higher number of t…
Determinantes de la divulgación de información sobre sostenibilidad en los gobiernos locales de Latinoamérica
2022
This paper analyses the socioeconomic factors that influence the disclosure of sustainability information on 99 local government websites in 2018 in countries that make up the Pacific Alliance (PA) in Latin America, associated with internal and external demands that public entities have for accountability in social and environmental issues. We use as methodology a content analysis of the sustainability information disclosed by local entities on their websites and a regression of Ordinary Least Squares (OLS). This article shows empirical evidence that the size, budget capacity and the economic level of the municipality are factors associated with the sustainability disclosure on websites due…
