An open-source instrumentation package for intensive soil hydraulic characterization
2020
International audience; We present a new open-source and modular instrumentation package composed of up to ten automatic in- filtrometers connected to data acquisition systems for automatic recording of multiple infiltration experiments. The infiltrometers are equipped with differential transducers to monitor water level changes in a Mariotte re- servoir, and, in turn, to quantify water infiltration rates. The data acquisition systems consist of low-cost components and operate on the open-source microcontroller platform Arduino. The devices were tested both in the laboratory and on different urban and agricultural soils in France and India. More specifically, we tested three procedures to t…
On the satisfiability problem for fragments of two-variable logic with one transitive relation
2019
Abstract We study the satisfiability problem for two-variable first-order logic over structures with one transitive relation. We show that the problem is decidable in 2-NExpTime for the fragment consisting of formulas where existential quantifiers are guarded by transitive atoms. As this fragment enjoys neither the finite model property nor the tree model property, to show decidability we introduce a novel model construction technique based on the infinite Ramsey theorem. We also point out why the technique is not sufficient to obtain decidability for the full two-variable logic with one transitive relation; hence, contrary to our previous claim, [FO$^2$ with one transitive relation is deci…
Piccola ontologia della relazione di coppia
2020
Si parla del nostro tempo come di un’epoca post-familiare, per intendere il declino o – per alcuni – il tramonto della famiglia nelle società occidentali della tarda modernità. Il fenomeno, a ben vedere, appare molto complesso e il «grande trambusto» non riguarda solo la vita familiare, porta anche a parlare di «sensibile mutamento» della relazione di coppia e di «evaporazione» dei rapporti genitoriali, in particolare della figura del padre. Per poter interpretare adeguatamente il cambiamento e la complessità, qualche autore ha proposto di cercarne la radice in una «sostanziale trasformazione dell’intimità»: una vera e propria «metamorfosi» del modo di sentire e di vivere l’affettività; asp…
Occurrence of DBPs in Drinking Water of European Regions for Epidemiology Studies
2016
International audience; A three-year study was conducted on the occurrence of disinfection by-products (DBPs) - trihalomethanes (THMs), haloacetic acids (HAAs), and haloacetonitriles - in drinking water of regions of Europe where epidemiology studies were being carried out. Thirteen systems in six countries (i.e., Italy, France, Greece, Lithuania, Spain, United Kingdom) were sampled. Typically chlorinated DBPs dominated. However, in most of Catalonia (Spain) and in Heraklion (Greece), brominated DBPs dominated. The degree of bromine incorporation into the DBP classes was in general similar among them. This is important, as brominated DBPs are a greater health concern. In parts of Catalonia,…

The Constraints of Vehicle Range and Congestion for the Use of Electric Vehicles for Urban Freight in France
2015
The 9th International Conference on City Logistics, Tenerife, Espagne, 17-/06/2015 - 19/06/2015; Electric vehicle is a solution to reduce pollutant emissions from road urban freight. This paper assesses the potential CO2 reduction by transferring urban freight from diesel to electric vehicles while simultaneously looking at the two main technical constraints: electric vehicle range and the impact on congestion linked to change diesel heavy duty vehicles (with a load up to 25 tons) to much smaller electric vehicles. The data used has been computed from a survey (ECHO) that describes in details a very large sample of French shipments. Two scenarios were set up, which differ mainly by the type…
Effect of concurrent resistance and sprint training on body composition and cardiometabolic health indicators in masters cyclists
2016
In older previously sedentary individuals endurance training imposes a more effective stimulus to enhance cardiometabolic health compared with resistance or sprint training. We examined the effect of replacing a portion of endurance training with combined resistance and/or sprint training and how this influences cardiometabolic health indicators in masters endurance cyclists. Twenty-seven well-trained male road cyclists (53.7± 8.2 years) were allocated to a resistance and track sprintcycling training group (RTC, n= 10), an endurance and track sprint-cycling group (ETC, n = 7) or a control endurance group (CTRL, n = 10). Both the RTC and ETC groups completed a 12-week intervention of specifi…
Suspended particulate matter fluxes along with their associated metals, organic matter and carbonates in a coastal Mediterranean area affected by min…
2016
International audience; A study of suspended particulate matter (SPM) fluxes along with their associated metals, organic matter and carbonates, was conducted off the Mejerda River outlet in May 2011 and in March and July 2012 at depths of 10, 20 and 40 m using sediment traps. SPM fluxes are more significant near the Mejerda outlet, especially in winter, but dissipate further offshore. Normalization reveals that the Mejerda is a major source of Pb, Zn, Cd, Cu, Ni, and Co, all of which are the result of human activities. In contrast, Fe, Mn and N are of authigenic origin. The enrichment factor shows that Pb, Zn and especially Cd are the most highly polluting metals off the Mejerda outlet. Thi…
Stark ionization of atoms and molecules within density functional resonance theory
2013
We show that the energetics and lifetimes of resonances of finite systems under an external electric field can be captured by Kohn–Sham density functional theory (DFT) within the formalism of uniform complex scaling. Properties of resonances are calculated self-consistently in terms of complex densities, potentials, and wave functions using adapted versions of the known algorithms from DFT. We illustrate this new formalism by calculating ionization rates using the complex-scaled local density approximation and exact exchange. We consider a variety of atoms (H, He, Li, and Be) as well as the H2 molecule. Extensions are briefly discussed.
On the Syntax of Fronted Adverbial Clauses in Two Tyrolean Dialects: The Distribution of Resumptive Semm
2023
Abstract This chapter discusses adverbial resumption in two Tyrolean dialects, Meranese and Mòcheno, which represent two privileged environments for investigations on microvariation. We show that certain classes of fronted adverbials are resumed in both languages by the resumptive element semm (lit. “there, then”), which behaves semantically like a generalized resumptive because it is used with a variety of adverbial clauses. However, unlike the Norwegian generalized resumptive studied by Christine Meklenborg, semm is a maximal category and cannot resume nominal arguments. We demonstrate that resumption with semm is limited to central adverbial clauses (e.g. temporal clauses), while periphe…
