Développement opérationnel en grandes cultures semées en ligne d’une rampe de pulvérisation grande largeur localisée sur le rang
2019
National audience; Pour réduire l’utilisation des herbicides, une des solutions possibles est de ne traiter que le rang en post-levée et de biner l’inter-rang ensuite. Terres Inovia, en collaboration avec la Coopérative Agricole Lorraine, a mis en place des essais au champ sur colza et tournesol avec la rampe localisée Marechal, dans le but de mettre au point cette technique pour des rampes de grande largeur avec une bonne qualité de pulvérisation sur le rang et un type de guidage adapté à des terres à colza, plus irrégulières que les terres à betterave sur lesquelles la rampe avait été développée. L’objectif est également d’évaluer les efficacités de la technique (satisfaction du désherbag…
Das Bleigewicht aus dem Hofareal der Fürstin von Vix
2021
International audience; The Lead Weight from the Courtyard of the Lady of VixThe Mont Lassois near Vix, Dép. Côte d’Or, as well as the Heuneburg, counts as one of the best researched princelyseats in the early Celtic western Hallstatt zone. In 1953 the late Hallstatt grave of Vix was discovered. The old excavations(1930-1974) have been reactivated by the German-French research project »Celtic Princely Seats West of theRhine« (1991-1997) and the French PCR-project (Projet collectif de recherche) »Vix and its Environment« (since 2002)with the participation of the universities of Dijon, Kiel, Vienna and Zurich. During the investigation of the late Hallstattcourtyard of the Lady of Vix on the h…
Das Bleigewicht aus dem Hofareal der Fürstin von Vix auf dem Hochplateau des Mont Lassois.

Das Bleigewicht aus dem Hofareal der Fürstin von VixDer Mont Lassois bei Vix, Dép. Côte d’Or, zählt neben der Heuneburg zu den am besten erforschten Fürstensitzen imfrühkeltischen Westhallstattkreis. 1953 wurde das späthallstattzeitliche Fürstinnengrab von Vix entdeckt. Im Rahmendes deutsch-französischen Forschungsprojektes »Keltische Fürstensitze westlich des Rheins« (1991-1997) und desfranzösischen PCR-Projektes (Projet collectif de recherche) »Vix et son environnement« (seit 2002) mit Beteiligungder Universitäten Dijon, Kiel, Wien und Zürich wurden die Altgrabungen (1930-1974) wieder aufgenommen. Bei derUntersuchung des späthallstattzeitlichen Hofareals der Fürstin von Vix auf dem Hochpl…
Rapid Compression Machine. 2013.
2013
A rapid compression machine is a type of ideal internal combustion reactor which is well suited for gas phase kinetics studies and physical processes of combustion. These studies consist in recording the evolution of the reactivity and of the composition of the reacting mixtures as a function of temperature, pressure, residence time and the composition of the compressed mixture. Pressure measurement is used to analyse the evolution of the combustion process, but more recent studies couple pressure measurement with optical diagnostics in order to assess the homogeneity of the combustion process. Speciation based on rapid sampling of the intermediates formed, during the oxidation of the fuel,…
What makes the difference : PIAAC as a resource for understanding the problem-solving skills of Europe's higher-education adults
2019
The ever-evolving technological landscape is challenging adults' problem-solving skills. The central goal of higher education (HE) is to guarantee a high level of know-how, which is in line with the changing demands of technology at work and in everyday life. This study builds on European data from the Programme for the International Assessment of Adult Competencies (PIAAC) to understand adults' (N = 53,407) skills for solving problems in technology-rich environments. The study provides insight into the socio-demographic, work-related, and everyday factors that are associated with a strong and a weak problem-solving performance. The results indicate that HE adults stand out from adults with…

Galaxy clustering: a point process
2016
El 'clustering' de galàxies és l'agregació de galàxies en l'universe produida per la força de la gravetat. Les galàxies tendeixen a formar estructures de major tamany tal com 'clusters' o filaments que formen la xarxa còsmica ('Cosmic Web'). Aquesta Estructura a Gran Escala de l'Univers es pot entendre com el resultat de la distribució de galàxies, un procés en el qual totes les galàxies estan subjectes a forces comuns i comparteixen propietats universals. L'anàlisis d'aquesta distribució es pot realitzar amb técniques de processos puntuals, l'estudi de configuracions de punts sobre un marc. En aquesta tesi fem servir aquesta branca de la estadística en tres approximacions diferents: els es…

Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV
2018
Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
Planktivorous vendace (Coregonus albula) utilise algae-derived fatty acids for biomass increase and lipid deposition
2018
Spatial and seasonal variation in the abundance and composition of phytoplankton and other basal resources (bacteria, terrestrial detritus) influence the availability of essen-tial polyunsaturated fatty acids (PUFA) for upper trophic levels in lake food webs. We studied accumulation, composition and content of fatty acids in planktivorous ven-dace (Coregonus albula) muscle tissue during the summer feeding period (May to late September) in six boreal lakes. Vendace muscle fatty acid content increased from ~17.7 mg/g DW to ~28.1 mg/g DW from spring to summer, corresponding to a ~59% increase in total fatty acids. PUFA accounted for 45%–65% of all fatty acids, and the most abundant fatty acid …
