Mobility of Cr and V in Spent Oil Shale: Impact of Thermal Treatment
2013
Abstract Spent oil shale samples were evaluated for potential chromium and vanadium release upon aerobic combustion used in power generation, or anaerobic retorting used in shale oil recovery. Combusted samples released more Cr than retorted or raw samples due to chromate formation. The behavior of vanadium was just opposite in that more V was released from retorted than from aerobically combusted samples, probably due to reduced vanadyl cation formation.
Glimpses of the Hereafter in the Late-Medieval Thet Freske Riim
2014
The article analyzes a passage of the narrative poem Thet Freske Riim, one of the few non-legal texts preserved in Old Frisian. The passage in question is a digression describing the Joys of Heaven and the Horrors of Hell, which so far has attracted little attention in the scholarly literature on medieval accounts of the hereafter. The representations of the afterlife and its realms circulating in Medieval Europe draw inspiration from a wide body of both orthodox and apocryphal literature on ecstatic dreams, of which one of the most influential work is the Visio Sancti Pauli or Apocalypse of Paul. The study aims to identify – in the examined passage – themes and features of otherworldly lit…
Proximité/distance comme catégories d'analyse pour la communication médiée par ordinateur : l'exemple de Twitter en allemand
2019
Doctoral; Les nouvelles technologies de communication (Schmitz 2004) – des sms d’antan aux messages snapchat d’aujourd’hui en passant par les réseaux sociaux devenus plus traditionnels comme Facebook – ont changé le rapport du locuteur/scripteur à la face matérielle de l’échange linguistique (Dürscheid/Frick 2016) ainsi que le résume, pour l’allemand, le titre de Lobin (2018), digital und vernetzt – das neue Bild der Sprache. A la suite des nombreux travaux portant sur l’écriture sms (par exemple Reinkemeyer 2013) ou encore du projet Whats’up Switzerland (Dürscheid 2018a, 2018b), la plateforme de microblogging Twitter attire de plus en plus l’attention des linguistes en tant que forme de Co…
La durabilité du périurbain dépendant de l'automobile au regard des pratiques d'achat en ligne des ménages
2014
ASRDLF2014 - 51ème colloque de l'Association de Science Régionale de Langue Française : Métropolisation, cohésion et performances : quels futurs pour nos territoires ?, CHAMPS-SUR-MARNE, FRANCE, 07-/07/2014 - 09/07/2014; International audience; La dépendance automobile des territoires périurbains liée à une absence de commerces et de services pose la question de leur soutenabilité, voire de leur durabilité à l'aube probable d'une augmentation importante et continue des prix des carburants. Internet et plus particulièrement la vente en ligne sont en mesure de fournir une alternative propice au maintien des ménages dans ces territoires. En effet, grâce au e-commerce, les ménages n'auraient pl…
Anthropomorphism and social presence in Human–Virtual service assistant interactions: The role of dialog length and attitudes
2022
In this study, we delve into the perceived quality of recommendations provided by AI-based virtual service assistants (VSAs). Specifically, the role of the social presence of VSAs in influencing recommendation perceptions is investigated. We also explore how the social presence of a VSA is formed and how perceived anthropomorphism plays a vital role in shaping social presence and eventually instilling trust in VSAs among consumers. These relationships are examined in the context of online government services. The results indicate that consumer interaction with VSAs - manifesting via perceived anthropomorphism, social presence, dialog length, and attitudes - improves recommendation quality p…

Variation of extent of reaction in closed chemical equilibrium when changing the temperature at constant volume
2011
In this paper it is presented a thermodynamic analysis that aims to find the mathematical expression of the variation of extent of reaction with the infinitesimal variation in the temperature at constant volume of a chemical equilibrium mixture. The goal of this paper is to establish an alternative approach to avoid both the Le Chatelier's principle and the problems that emerge when trying to apply its qualitative statements. This attempt is based on the laws of thermodynamics.
Functional fixedness and functional reduction as common sense reasonings in chemical equilibrium and in geometry and polarity of molecules
2000
Many of the learning difficulties in the specific domain of chemistry are found not only in the ideas already possessed by students but in the strategic and procedural knowledge that is characteristic of everyday thinking. These defects in procedural knowledge have been described as functional fixedness and functional reduction. This article assesses the procedural difficulties of students (grade 12 and first and third year of university) based on common sense reasoning in two areas of chemistry: chemical equilibrium and geometry and polarity of molecules. In the first area, the theme of external factors affecting equilibria (temperature and concentration change) was selected because the ex…
Insatisfaction et restauration de la relation client-fournisseur par un système de management de la performance
2016
International audience; A travers une étude qualitative via la méthodologie de la recherche action, cet article permet d’enrichir les études existantes sur le management des relations client-fournisseurs en se focalisant sur la manière dont un fournisseur industriel, ici un bureau d’achats, réagit pour faire face au mécontentement de son client. Ce travail permet d’éclairer et de valider empiriquement le processus de résolution de conflit dans le but de maintien d’un client industriel. Nos résultats indiquent que le système de management de la performance combiné avec une communication régulière des résultats influence l’extension du contrat via son renouvellement.
Groundwater of Sicily (Italy) Close to Landfill Sites: Quality and Human Health Risk Assessment
2021
Groundwater close to three municipal solid waste landfill sites in Sicily (southern Italy) was sampled to determine the presence of contaminants and the risk associated with its possible use as drinking and sanitary water. Polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and metals were investigated. These target compounds are the most common pollutants present in leachates. Risk Assessment Guidance for Superfund (RAGS, US EPA) was used to assess human health risk. Ingestion, dermal, and total exposure to these xenobiotic contaminants in groundwater were evaluated, and the cancer and non-cancer risk indexes were c…
