Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2
2019
The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers. Optimal resolution is achieved with a dedicated calibration program that addresses the specific operating conditions of the 354 000 high-pressure drift tubes in the spectrometer. The calibrations consist of a set of timing offsets and drift time to drift distance transfer relations, and result in chamber resolution functions. This paper describes novel algorithms to obtain precision calibrations from data collected by ATLAS in LHC Run 2 and from a gas monitoring chamber, deployed in a dedicated gas fac…
Wireless power transfer system stability analysis for E-bikes application
2019
The present work reports the stability analysis of an Inductive Coupled Power Transfer (ICPT) System coupled to an electrical bike. The study has focused on two coupled coils with circular geometry and vertical disposition. In the first part of the work, the theoretical aspects related to the stability of wireless power systems are handled. In the second part, performing several simulations, varying the features of the considered configuration, the stability is looked for. In order to perform this process, the Ansys Maxwell software has been used, performing 3D simulations.
The Acquisition of Professional Expertise—a challenge for educational research
1997
This article examines the acquisition of professional expertise from the educational viewpoint and outlines emerging approaches to research on expertise. The starting points are the need to reflect the nature and content of expertise in the changing world and the aim to understand the preconditions for integrating the viewpoints of working life and education in developing prerequisities for expertise in educational contexts. The section after the Introduction briefly reviews how expertise has been conceptualized in recent research. The next section deals with the role of higher education in developing expertise from the viewpoint of constructivist approaches in research on learning. Then cu…
Etude des mécanismes physiologiques et moléculaires permettant la prise en charge des substrats hydrophobes par la levure Yarrowia lipolytica au nive…
2012
Yarrowia lipolytica can grow on many hydrophobic substrates and metabolize them via the β-oxidation pathway or store them into lipid bodies. The first contact between the cell and the hydrophobic substrates is by the cell wall. In this step, cell-wall proteins (CWP), β-glucane and chitin of the cell wall could play an important role for the adhesion and uptake of hydrophobic substrates. The aim of this work was to study the effect of a hydrophobic carbon source (compared with glucose) and the culture medium composition on the cell wall composition and the melanin production by Y. lipolytica. The results of our biochemical and molecular analysis showed that the presence of methyl oleate and …

A. Bavelas, 1950, Communication Patterns in Task-Oriented Groups. Version bilingue et commentée
2021
Ce document du groupe fmr présente une version bilingue et commentée de l'article d'Alex Bavelas, Communication Patterns in Task-Oriented Groups, paru en 1950 dans la revue Journal of the Acoustical Society of America. S'appuyant sur les seuls travaux de Kurt Lewin et de ses élèves, et donc ne mobilisant ni la sociométrie ni la théorie des graphes au sens strict, l'auteur propose un ensemble de mesures permettant de mesurer l'efficacité de la communication au sein d'une structure donnée. Cet article a eu une influence importante dans différents champs de recherche (analyse de réseaux sociaux, management, psychologie, etc.).
Parental and professional agency in terminations for fetal anomalies: analysis of Finnish women's accounts
2013
This study explores the construction of parental and professional agency in the written accounts by women who have undergone selective abortion (N=8). The analysis of the data was based on qualitative, linguistic discourse analysis. The accounts indicate that the mothers themselves exhibited both strong and weak agency during the process of prenatal diagnosis. The role of the professionals was usually discussed in these accounts concerning only the phases of pregnancy when something out of ordinary had been detected. After the termination, the mothers expressed that they were forced to exhibit strong agency and find ways to cope with their distress unaided due to a lack of professional supp…

Biosynthesis of the Collagen-like C1q Molecule and its Receptor Functions for Fc and Polyanionic Molecules on Macrophages
1983
At the beginning of the nineteenth century, knowledge of immunity was limited to a few practical methods based on empirical observations, e.g., the observation by Jenner in 1798 that inoculation with cowpox material induced an immunity to smallpox. The discoveries by Louis Pasteur and Robert Koch that microorganisms caused fermentations and were responsible for a number of infectious diseases, greatly advanced the concepts of susceptibility and immunity in a limited number of diseases. In the late nineteenth century, the complement system was discovered by Fodor(1887), Nuttall(1888), and Buchner (1889a, b) through studying the bactericidal action of blood serum. It was recognized that killi…
