Lamamra, N., Kuehni, M., & Rey, S. - Finalités et usages de la formation professionnelle
2022
Une rencontre internationale, « 9es Rencontres Jeunes et Sociétés en Europe et autour de la Méditerranée » (RJS9), sur la formation professionnelle (FP) et l’insertion a eu lieu à Lausanne en octobre 2018. Elle avait pour objectif de « faire un état des lieux des différents systèmes de la FP (axe 1), d’en définir les publics (axe 2), de questionner leur impact en termes d’insertion sur le marché du travail (axe 3) ou encore d’en interroger la portée socialisatrice (axe 4) »...
Valuing Variability: Dynamic Usage-based Principles in the L2 Development of Four Finnish Language Learners
2020
The general aim of this study is to trace the second language (L2) development of four beginner learners of Finnish over one academic year from a dynamic usage-based perspective. Contrary to many previous studies, this study starts out from meanings, not forms. In other words, an onomasiological approach is adopted. The aim is to investigate what kind of constructions the learners use to express 1) evaluation and 2) existentiality. In line with a dynamic usage-based approach, the goal is to investigate three aspects of development: 1) the interaction between different linguistic means used to express a certain meaning and between the instruction and learning trajectories, 2) variability pat…
The lost mother tongue : An interview study with Finnish war children
2015
This article presents the third study of an interview investigation concerning 10 Finnish war children who were evacuated during the World War II to Sweden and who did not return to live in Finland after the war. The focus is on how they remembered or did not remember their early experiences of displacement and on how they expressed thoughts about their childhood and their adult life. We found that all of them as adults still bore signs of trauma. The younger the children were at the time of the evacuation, the more difficult or even impossible it was for them to think or fantasize about the past. It was consequently not possible for them to work through their experiences of loneliness, abs…
Two-laser multiphoton adiabatic passage in the frame of the Floquet theory. Applications to (1+1) and (2+1) STIRAP
1998
We develop an adiabatic two-mode Floquet theory to analyse multiphoton coherent population transfer in N-level systems by two delayed laser pulses, which is a generalization of the three-state stimulated Raman adiabatic passage (STIRAP). The main point is that, under conditions of non-crossing and adiabaticity, the outcome and feasibility of a STIRAP process can be determined by the analysis of two features: (i) the lifting of degeneracy of dressed states at the beginning and at the end of the laser pulses, and (ii) the connectivity of these degeneracy-lifted branches in the quasienergy diagram. Both features can be determined by stationnary perturbation theory in the Floquet representation…
Fluorimetric determination of captopril by flow injection analysis
1991
A flow injection analysis procedure is proposed for the determination of captopril. The sample solution was directly injected into the carrier-reagent stream which was prepared by a solution of ceric ions in 0.25 M sulfuric acid. The procedure is based on the fluorimetric monitoring of the formed Ce(III). Chemical, FIA, and instrumental parameters were optimized and the procedure is applied to the captopril determination in pharmaceutical formulations with competitive precision and adequate accuracy.
FIA-fluorimetric determination of adrenaline by oxidation with a solid-phase reactor of manganese dioxide incorporated in polyester resin beads
1995
Abstract The FIA-spectrofluorimetric determination of adrenaline was carried out by reaction of the drug with manganese dioxide entrapped in a polymeric material in a solid-phase reactor; the oxidized drug was monitored fluorimetrically at 540 nm (Ioxg. 330.0 nm). The calibration graph for adrenaline was linear over the range 0.5 - 20 μg ml−1 with a relative standard deviation of 2.0% (at 5 ug ml−1) and the sample throughput of 65 h−1. The influence of foreign compounds was studied and the method was applied to the determination of adrenaline content in a pharmaceutical formulation . ∗Present address: Institut of Chemistry, Warsawa University, Bialystok Branch, Bialystok, Poland.
Spectrophotometric and Fluorimetric Determination of 9-Amino Acridine by Flow Injection Analysis
1990
Abstract The spectrophotometric and fluorimetric determination of 9-amino acridine is carried out by means of the FIA procedures and on the basis of its own color or fluorescence. The methanol used as a carrier stream resulted in a significative increase in sensitivity and sample throughput. The method is applied to the drug determination in pharmaceutical formulations.
Spectrophotometric determination of promethazine by flow injection analysis and oxidation by CeIV
1992
A flow injection analysis (FIA) procedure is proposed for the determination of promethazine. The sample solution is directly injected into the carrier-reagent stream which comprises a solution of ceric ions in a sulphuric acid medium. The absorbance at 514 nm from the red colour developed by the oxidation of promethazine is measured. Effects of foreign substances have been investigated and the procedure has been applied to the determination of promethazine in a pharmaceutical formulation (tablets).
Bio-predictive tablet disintegration: Effect of water diffusivity, fluid flow, food composition and test conditions
2013
Abstract Food intake may delay tablet disintegration. Current in vitro methods have little predictive potential to account for such effects. The effect of a variety of factors on the disintegration of immediate release tablets in the gastrointestinal tract has been identified. They include viscosity of the media, precipitation of food constituents on the surface of the tablet and reduction of water diffusivity in the media as well as changes in the hydrodynamics in the surrounding media of the solid dosage form. In order to improve the predictability of food affecting the disintegration of a dosage form, tablet disintegration in various types of a liquefied meal has been studied under stati…
