Electoral digital communication : a new stage in the commodification of politics?
2022
Online election campaigns and associated professional practices in digital and electoral communication have brought electoral work to new horizons where performance through web technologies and the exploitation of online data mark a new stage in the commodification of politics. Through digital communicators and specialists, campaign teams learn new methods and professional practices to manage an election campaign. The introduction of new digital tools for the administration of communication operations thus induces new processes whose object of this research is to be interested, on the basis of online supports and interviews, The European Parliament’s Committee on Employment, Social Affairs …
Lifelong exposure to low dose xeno-hormones in rats : multi-generational effects of xeno-hormone mixtures on taste preferences, maternal behavior, an…
2012
During the last decade, the issue of health-related endocrine disruptors (ED) has been extended to the toxicity of mixtures. The objective of this study was to define the effects of lifelong exposure to ED mixtures, at low doses defined as "non-harmful" by the authorities. In this aim, the effects of mixtures combining genistein, vinclozolin and bisphenol A, have been investigated in the rat by using an integrative and multi-generational experimental approach which takes into account maternal behavior, feeding behavior and development. Our results show that these mixtures could: a) reduce maternal behavior, b) change taste preferences (sweet, salty), c) affect the development from the in ut…
Gingival and submandibular lymph node metastasis of sigmoid colon adenocarcinoma
2010
Introduction: Metastatic tumors of oral and maxillofacial region compromise 1% of all malignant oral neoplasms. Most commonly affect the jaw bone and less commonly intraoral soft tissues. They originate mainly from primary tumors of lung, breast, colon-rectum, prostate and kidney. Case report: a 77 years old man with history of sigmoid colon adenocarcinoma and liver metastasis. Two years later of being free of disease, he presented with submandi- bular lymphadenopathy and a gingival mass in right upper jaw. Fine needle aspiration of the node and biopsy of the gingival mass were performed. The cytological smears showed cohesive cell groups on a necrotic background. Biopsy examination showed …
Assessment of the embodied energy for manufacturing and laying a submarine outfall pipeline
2008
The Life Cycle Assessment (LCA) methodology was applied to a submarine outfall pipeline intended for the disposal of treated MWW in the South Tyrrhenian Sea, on Western Coast of Sicily. The pipe serves 115 thousands inhabitants; it is 3,1 km long with an outer diameter of 800 mm and is allocated in a submarine trench down to 18 m bsl. The pipe ends with a multiport diffuser with outer diameter 500 mm. The whole pipeline is made in HDPE and is statically stabilized by cast iron rings and concrete anchor blocks. From the detailed constructive project of the pipeline the most relevant items involved were drawn and the most important ones were selected, both as materials employed and as laying …
Shallow submarine gas manifestations in the Aegean Sea: preliminary catalogue and geochemical characterization
2017
The Aegean area, like other regions of intense geodynamic activity, is characterised by extensive geogenic degassing. Gas manifestations widespread on land are also very frequent underwater. The present study aims at producing a first catalogue of these manifestations together with the geochemical characterization of the emitted gases. Sixty-one samples at 21 different sites have been collected by diving up to 15 m depth, mainly along the south Aegean active volcanic arc (SAAVA). The sites displayed very different gas fluxes. Most of them showed a very sluggish gas bubbling while a few had spatially large and strong bubbling. The most intense manifestation has been found at Kos Island along…
Influence of total solids concentration on membrane permeability in a submerged hollow-fibre anaerobic membrane bioreactor.
2012
The main aim of this work was to study the influence of the mixed liquor total solids (MLTS) concentration on membrane permeability (K 20) in a submerged anaerobic membrane bioreactor (SAnMBR) pilot plant, which is equipped with industrial hollow-fibre membranes and treats urban wastewater. This pilot plant was operated at 33°C and 70 days of SRT. Two different transmembrane fluxes (13.3 and 10 LMH) were tested with a gas sparging intensity of 0.23 Nm 3 m -2 h -1 (measured as Specific Gas Demand referred to membrane area). A linear dependence of K 20 on MLTS concentration was observed within a range of MLTS concentration from 13 to 32 g L -1 and J 20 of 10 LMH. K 20 was maintained at sustai…
Sea surges at Monaco and Nice: present-day and future variability (1998-2100).
2018
Sea surges arerapid increase of the level of the sea under atmospheric conditions that could lead to coastal submersion havingstrong impacts especially for coastal towns of the French Riviera such as Nice and the principality of Monaco.Interannual variability of the highest surges at Monaco is robustly simulates by a linear regression usingbarometric conditions over [3-10°E]-[40-45°N] as a predictor. According to 15 global circulation models,highest surges at Monaco could stay stationary for two different climate change scenarios (RCP4.5 andRCP8.5).
Multiscale analyses and characterizations of surface topographies
2018
International audience; This work studies multiscale analyses and characterizations of surface topographies from the engineering and scientific literature with an emphasis on production engineering research and design. It highlights methods that provide strong correlations between topographies and performance or topographies and processes, and methods that can confidently discriminate topographies that were processed or that perform differently. These methods have commonalities in geometric characterizations at certain scales, which are observable with statistics and measurements. It also develops a semantic and theoretical framework and proposes a new system for organizing and designating …
Protein-lipid interactions at the air-water interface.
2010
International audience; Protein−lipid interactions play an important role in a variety of fields, for example in pharmaceutical research, biosensing, or food science. However, the underlying fundamental processes that govern the interplay of lipids and proteins are often very complex and are therefore studied using model systems. Here, Langmuir monolayers were used to probe the interaction of a model protein with lipid films at the air−water interface. The protein β-lactoglobulin (βlg) is the major component in bovine milk serum, where it coexists with the milk fat globular membrane. During homogenization of milk, βlg adsorbs to the interface of lipid fat globules and stabilizes the oil-in-…
Europe's offshore winds assessed with synthetic aperture radar, ASCAT and WRF
2020
Europe's offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of synthetic aperture radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced Scatterometer (ASCAT) ocean wind maps. The wind statistics at 10 and 100 m above mean sea level (a.m.s.l.) height using an extrapolation procedure involving simulated long-term stability over oceans are presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid spacing with data …
