Intérêt de l'étude microscopique du produit de brossage dans le diagnostic des pulicoses chez le chat et le chien : étude expérimentale

Le diagnostic des pulicoses chez le chien et le chat se fait soit par mise en évidence des parasites adultes dans le pelage des animaux infestés soit par mise en évidence des déjections de puces. Il est classiquement recommandé d’utiliser alors la technique du buvard imprégné. Cependant, une autre technique consistant à examiner au microscope le produit de brossage ou de peignage est parfois préconisée. Ce travail de thèse a consisté à évaluer l’intérêt de l’utilisation du microscope pour ce diagnostic par rapport à l’utilisation du papier buvard. Afin de comparer les deux techniques, 255 produits de brossage de chats et de chiens de propriétaires ont été prélevés et analysés en double aveugle. L’analyse des résultats indique que la technique du papier buvard est plus efficace que l’examen au microscope mais que l’association des deux techniques dans des pulicoses de faible intensité est à préconiser

Determination of vibration-rotation lines intensities from absorption Fourier spectra

The method presented allows the line intensities to be calculated from either their equivalent widths, heights, or quantities deduced from spectra obtained by Fourier spectrometry. This method has proven its effectiveness in measuring intensities of 60 lines of the molecule H2O with a precision of 10%. However, this method cannot be applied to isolated lines

Computational Cognitive Models of Summarization Assessment Skills

This paper presents a general computational cognitive model of the way a summary is assessed by teachers. It is based on models of two subprocesses: determining the importance of sentences and guessing the cognitive rules that the student may have used. All models are based on Latent Semantic Analysis, a computational model of the representation of the meaning of words and sentences. Models' performances are compared with data from an experiment conducted with 278 middle school students. The general model was implemented in a learning environment designed for helping students to write summaries

Europeanization through its instrumentation:Benchmarking, mainstreaming and open method of coordination… Toolbox or Pandora’s nox ?

Understanding Europeanization through its instrumentation raises the issue of the supposed neutrality of policy tools used as soft modes of action. The aim of this article is to assess how this ‘new governance’ tends to guide policy-making on a specific path. Indeed, European construction cannot be restricted to the direct impact of Community law or to the indirect effects of economic integration. A new form of non-constraining co-ordination has been developing since the mid-1990s. In order to explain how the cognitive mechanisms of Europeanization work, we open the ‘toolboxes’ that allow European institutions to have an effect on national representations and practices. The use of benchmarking for building the European Research Area, the elaboration of gender equality policy according to the principle of mainstreaming, and the open method of co-ordination (OMC) in the field of pension reforms, illustrate how such policy instruments lead national governments to meet the competitiveness requirements of the Lisbon strategy

Environnement intérieur : vers une prise de conscience française de l'enjeu sanitaire

National audienceLargement prise en compte depuis une vingtaine d'années aux Etats-Unis, au Canada et dans les pays nord-européens, la problématique de l'environnement intérieur semble émerger concrètement en France

VOCs and formaldehyde emissions from cleaning products and air fresheners

International audienceHuman indoor exposure to Volatile Organic Compounds (VOCs) may be associated with the use of household products. However little is known about their emissions and to what extent they contribute to indoor air pollution. The French Agency for Environmental and Occupational Health Safety (Afsset) conducted tests in order to characterize VOCs emissions from 32 consumer products: air fresheners, glass cleaners, furniture polishes, toilet products, carpet and floor cleaning products. All experiments were conducted by the Scientific and Technical Centre for Building (CSTB) in realistic conditions of use (in emission test chamber or in an experimental house). Results show that the use of consumer products can lead to high indoor VOCs concentrations. Some of them are toxic airborne contaminants. The link between formaldehyde emissions and product compositions is discussed. Finally, formaldehyde concentrations are compared to the indoor air quality guideline value proposed by Afsse
