Development of eco-friendly processes for the synthesis of biobased solvents and organocatalysts
2018
Oxazolidinones are promising compounds for industrial applications, but nowadays there is not convenient method to produce them on large scale, because of the use of reactants and metallic catalysts harmful for health and environment. A new synthesis method of these compounds was thus elaborated using aminoalcohols and diethyl carbonate. This reaction is catalysed by a biobased imidazolium hydrogen carbonate which is produced by an electrochemical pathway in order to reduce its impact on the environment.This oxazolidinones synthesis method was then applied to the synthesis of a biobased oxazolidinone. To achieve this, an aminoalcohol synthesis was realised, and its structure was established…
Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis
2018
The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of 5 scarce raw materials and the urgent environmental protection requirements are forcing the change of 6 pavement industry and academia community’s research endeavors towards the development of low 7 emissions road paving technologies able to significantly reduce mixing and compaction temperature as 8 well as the consumption of virgin raw materials. One set of relatively recent technologies in the field of 9 pavement materials that aims at addressing those concerns are the warm mix asphalt (WMA). In fact, 10 they have the potential to allow the reduction of energy consumption and airborne emissions d…
Cycles de vie et événements-ruptures dans la franchise : conséquences sur le pilotage de la relation franchiseur-franchisés. Une approche par le cont…
2007
What is franchise? It's a beautiful wedding. At first we believe it. Unfortunately in a wedding he ends up having moments of lassitude, moments of disappointment and then arguments. "A network is based on the human relationship, so it remains fragile. Anyway, if a network has problems, it's because the franchisor has failed. A franchisee has no reason to be at war with his franchisor if all goes well. And if it goes wrong is that the franchisor has failed at some point in the relationship, in the result or in the products. This is because there is a problem with the headend. "
ALOMYSIS: la modélisation pour gérer les populations de vulpin
2009
National audience; Comment contrôler les graminées, et en particulier le vulpin, sans avoir recours aux herbicides ? En combinant un maximum de techniques. Un modèle mathématique mis au point par l’INRA permet de simuler l’impact de la succession culturale et des itinéraires techniques sur les populations de vulpin.
Augmented context based on prediction for efficient knowledge reuse of business knowledge in design
2017
Works on the design context augmentation in product design, makes it possible to make awareness designers on their choice in the design for assembly. The presented approach will conclude on the method to develop a informatic system, based on case studies of mechanical design. The purpose of the project is to capture the design intent, in order to provide useful assistance to stakeholders, such as design support, decision making, verification/validation, and data structuring.
Thermal Engine and Climate Change Challenge
2021
Thermal engines have dominated sectors of economy, and particularly transportation. Their current development and state of the art are the results of XXth century priorities related to economy and environment. In the future, thermal engines will face the challenge of emerging technologies in the frame of sustainable mobility and development. After an analysis of functioning principles and perspectives of development, particularly of combustion engines, thermal engines are compared to other realistic scenarios for transports applications in well-to-wheel and life cycle analysis.
L'audience et l'influence d'une revue mesurée à travers Internet : une application à Finance Contrôle Stratégie
2009
This article aims to show the interest of statistics available on the Internet concerning consultations of abstracts, downloads and citations of articles to assess the attractiveness and influence of a scientific review. This interest is illustrated by the case of the review Finance Contrôle Stratégie on the basis of the statistics provided by Repec and Publish or Perish. Beyond the findings that confirm the good performance of FCS and the usefulness of these statistics for the management of a scientific review, the article also provides insights into the life cycle of an article and the choice of the language of publication.
