Weryfikacja kinetycznego modelu polimeryzacji etylenu wobec metaloorganicznych katalizatorów wanadowych na nośniku magnezowym
1998
The kinetic studies are reviewed on low-pressure polymerization of ethylene over two types of organovanadium catalysts, viz., MgCl 2(THF) 2/VCl 4/Et 2AlCl and MgCl 2(THF) 2VOCl 3Et 2AlCl, each deposited on a magnesium carrier. The polymerization rate was found to be directly related to the catalyst and monomer concentrations (Figs. 2 and 3), unless when the access of the monomer to the reactive V-C bond is restricted by diffusion. Polymer chain termination step was found to result from the reaction of the transfer onto the monomer and to be associated with the regeneration of the active site on which a new macromolecule can be formed. A kinetic model was developed for the ethylene polymeriz…

A Comparative Eye Tracking Study of Usability—Towards Sustainable Web Design
2021
Websites are one of the most frequently used communication environments, and creating sustainable web designs should be an objective for all companies. Ensuring high usability is proving to be one of the main contributors to sustainable web design, reducing usage time, eliminating frustration and increasing satisfaction and retention. The present paper studies the usability of different website landing pages, seeking to identify the elements, structures and designs that increase usability. The study analyzed the behavior of 22 participants during their interaction with five different landing pages while they performed three tasks on the webpage and freely viewed each page for one minute. Th…
L’éducation à l’entrepreneuriat : quelle influence sur les compétences entrepreneuriales et le projet de création des étudiants ? Cas de l’Université…

Ce séminaire a eu lieu en visioconférence; International audience; Dans la littérature, les chercheurs mettent souvent en exergue un impact positif et significatif de l’éducation à l’entrepreneuriat sur la volonté de créer de même que sur la concrétisation de ce projet à terme. Si des programmes de formations ont émergé un peu partout sur le territoire burkinabé, notamment dans certains établissements d'enseignements supérieurs, il n’existe cependant aucune étude à notre connaissance qui a examiné leur impact sur l’intention d’entreprendre. Cette étude propose ainsi d’analyser l’influence de l’éducation à l’entrepreneuriat – le fait de participer à une formation en entrepreneuriat - sur le …
