Effects of landscape composition on hoverflies (Diptera: Syrphidae) in mass-flowering crop fields within forest-dominated landscapes
2022
Agricultural intensification has led to structurally simplified landscapes with reduced and fragmented resources for farmland insects. However, studies on the effects of landscape composition on farmland insects have mainly been performed in areas dominated by open arable land and semi-natural grasslands, while studies from forest-dominated landscapes are scarce. This research examined the effects of landscape composition on hoverfly species richness and abundance in arable land in boreal forest-dominated landscapes. Hoverflies were sampled in 22 mass-flowering caraway (Carum carvi) fields in Central Finland using pan traps. The effects of landscape composition on species richness and abund…
Impacts interculturels au Néolithique moyen. Du terroir au territoire : sociétés et espaces.
2006
International audience; INTERACTIONS CULTURELLES ET EMPRISE DES SOCIÉTÉS NÉOLITHIQUES SUR LES ESPACES"Interactions culturelles", "espaces", voilà bien des sujets que certains pourraient qualifier de rebattus ! Diverses éditions antérieures du colloque néolithique n'ont-elles pas fait de l'un ou l'autre leur thème central ? Leur choix, pour ce colloque ne relèverait-il alors que d'une soumission aux vogues du moment ? On privilégie en effet volontiers ces derniers temps les débats touchant aux relations interculturelles. Et il paraît de bon ton de sacrifier aux approches spatiales, quand ce n'est pas à leur seul instrument, le "SIG". Mais, au delà de ces considérations un peu simplistes, ce …
Winter long dry spells in the Mediterranean basin and associated atmospheric conditions : contemporary and future variability (1957-2100)
2017
In the context of climate change, as reflected by a dryer Mediterraneanbasin, this thesis focused on the study of the contemporary and future variability(1957-2100) of the wintertime (September to April) very long dryspells events (called VLDSe) in the Mediterranean basin. An original methodologywas developed in this thesis in order to define VLDSe as singularclimatic events, characterized by location, duration and spatial extent criteria.76 VLDSe were detected in the Mediterranean basin on the contemporaryperiod (1957-2013). These events are divided into 4 main geographicalpatterns: North-East, West, Scattered Localized and South-East. North-East and West configurations are associated with…
The energy and environmental impacts of Italian households consumptions: An input–output approach
2011
Abstract Promoting sustainable consumption and production patterns is a key challenge for the future, in order to use the Earth resources efficiently, to reduce the greenhouse gas emissions, and to decouple the economic growth from the environmental degradation. New or customized methods have to be applied to support decisions makers in the choice of environmental-friendly products, and to select policy priorities and sustainable strategies. A modified input–output model can aid to analyse the relationships among economic growth, energy consumptions and pollutants, in order to assess the energy and environmental impacts due to the actual production and consumption patterns. The following pa…
Life Cycle Assessment of Flow-Redox Cells: A Case Study
2022
European Union identified the battery value chain as strategic for achieving a sustainable and decarbonized economy. Focusing on the environmental sustainability of batteries, this paper presents an application of the Life Cycle Assessment methodology to three flow-redox cells characterized by electrodes made by different materials. The results are referred to one kWh of energy supplied by the cell during its useful life and are calculated following a “from cradle to grave” approach. Negligible differences (lower than 1.5%) are observed in the energy and environmental impacts of the three types of cells, mainly due to the type of electrode and the use phase. A dominance analysis shows that …

Energy and environmental life-cycle impacts of solar-assisted systems: The application of the tool “ELISA”
2020
Abstract Solar heating and cooling (SHC) systems can be relevant in the achievement of energy and climate European goals. The benefits of these technologies should be evaluated taking into account their life-cycle energy and environmental impacts, calculated by applying the Life Cycle Assessment (LCA). The development of a complete LCA can be difficult and time-consuming particularly for non-experts in LCA, discouraging them in developing the life-cycle assessments. To overcome this issue, the paper presents “ELISA - Environmental Lifecycle Impacts of Solar Air-conditioning systems”, a user-friendly simplified tool for estimating the life-cycle energy and environmental benefits/impacts of s…
Gut microbiota disturbance during antibiotic therapy: a multi-omic approach
2014
It is known that the gastrointestinal tract (GIT) microbiota responds to different antibiotics in different ways and that while some antibiotics do not induce disturbances of the community, others drastically influence the richness, diversity, and prevalence of bacterial taxa. However, the metabolic consequences thereof, independent of the degree of the community shifts, are not clearly understood. In a recent article, we used an integrative OMICS approach to provide new insights into the metabolic shifts caused by antibiotic disturbance. The study presented here further suggests that specific bacterial lineage blooms occurring at defined stages of antibiotic intervention are mostly associa…
À la recherche des maillages communaux d'antan. Présentation du projet ANR COMMUNES et de quelques résultats préliminaires
2020
The COMMUNES project aims: 1) to produce the first H-GIS in the world providing annualised boundary data for all French municipalities from the Revolution to the present day. Each spatial unit will include population data and metrics of access to networks of transport; 2) to develop a multimodal model of transport to allow the dynamic analysis of the relationship between economic and demographic changes and accessibility from the end of the 18th century to the present day; 3) to represent and analyse on a very fine scale some key demographic and socio-economic phenomena. Our method for reconstructing historic administrative boundaries combines the study of historical and cartographic source…
THE ROLE OF NATIONAL AUDIOVISUAL COUNCIL FROM ROMANIA AND THE IMPACT ON ELABORATING COMMUNICATION STRATEGIES
2015
In the present research I will analyze the reactions and opinions of the interviewed persons regarding the role of National Audiovisual Council from Romania, and also it will be analyzed the impact on elaborating communication strategiesy. At the same time, it is aimed at presenting some comparisons between: the general activity of the National Audiovisual Council and the displaying of main objectives, as well as the expectations of the public opinion about the work of this institution. Thereby, I will use the interview as a qualitative research method, to confirm or infirm the hypothesis of the present research.
