Déterminer le goût de l’eau ne coule pas de source
2008
Describing the taste of water is a challenge since drinking water is supposed to have almost no taste. In this study, different classical sensory methodologies have been applied in order to assess sensory features of water. Nevertheless, these methodologies present drawbacks so a new methodology based on the comparison between water samples named “Polarized Sensory Positioning” (PSP) has been developed enabling to easily define the sensory characteristics of water without presenting too many samples. Finally, this new method provides new sensory data and could be extended to other products.
Factors of good visual outcome in acute post-cataract endophthalmitis (friends group)
2009
International audience; Purpose: To analyze initial clinical factors of good visual outcome in patients with acute endophthalmitis following cataract surgery. Methods: A prospective study was performed in 4 University hospital (Dijon, Grenoble, Lyon, Saint-Etienne, FRIENDS group) on 100 patients with acute post-cataract endophthalmitis. Factors related to cataract surgery (complications), the initial presentation and the microbiological identification were analyzed according to the final visual outcome using univariate and multivariate analysis (SPSS 12.0). Results: 46% out of the patients had a final visual acuity less than or equal to 0.3 logMar (good visual outcome) at 6 months while 10%…
Accompagner les réseaux DEPHY-FERME et DEPHY EXPE dans la caractérisation de l’effet des systèmes de culture sur la flore adventice
2015
To characterize weed pressure in agricultural fields of the DEPHY Ecophyto networks, the "weeds" working group of the CASIMIR project, helped by crop and weed experts working for the french crop institutes, developed two methods (CASIMIR DEPHYFARM and CASIMIR DEPHYEXPE) to survey weeds in main crops. The objectives of these methods are: (i) with shortterm concern, assess the efficacy of farming practices to manage weeds within the crop season, (ii) with longterm concern, assess the effect of cropping system (farming practices and crop sequence) on the dynamic of the weed communities. The CASIMIR DEPHYFARM method is based on walk away surveys made within a 2000m² reference plot where t…
Close-Range Photogrammetric Tools for Epigraphic Surveys
2016
In this article, we present a method to carry out a computerized epigraphic survey of historic stones and their engraved epigraphy. In fact, the preservation of archaeological objects has always been an issue of concern for the research community. On the one hand, the fragility of the objects limits their study. On the other hand, such objects are housed in museums, libraries, and institutions worldwide, locations that significantly limit their accessibility. Different survey methods have been carried out in these attempts to overcome the aforementioned limitations. Among them, the MicMac open source software was used in this work to survey and process the dense correlation of the hieroglyp…
La historiografía y la teoría social. Una discusión desde la historia de lo premoderno
2018
This article analyses the importance of social theory for historiography. It deals specifically with pre- modern historiography and the uses that it has for social theory. Through an example from the history of conflict resolution in the central Middle Ages, it will be shown how social theory plays a primordial role in the engagement of certain problems that cannot be tackled by the sole use of the tools which tradition- ally characterise history and its so-called 'auxiliary disciplines'.

L'animation cartographique pour la représentation des trajectoires individuelles : Propositions sémiologique et application sur GoogleEarth
2011
International audience; Dans de nombreuses thématiques, la cartographie animée est entrevue désormais comme l'une des solutions pour représenter l'information et mieux comprendre les phénomènes étudiés. Poussée par l'émergence rapide de nouvelles techniques et par un potentiel encore peu exploré, cette cartographie fait l'objet de recherches qui s'expriment tant d'un point de vue conceptuel et théorique (Perterson. Il existe ainsi une grande effervescence autour d'un mode de représentation qui, s'il n'est pas nouveau, acquiert désormais une capacité de mise en oeuvre notamment à l'aide du webmapping. Cependant, beaucoup de travaux gardent encore une conception de l'animation réductrice en n…
De quelques difficultés à cumuler ses savoirs sur les phénomènes éducatifs : l'exemple de la démocratisation de l'enseignement
2002
This paper aims at showing the difficulties regarding the building up of knowledge about educational processes, especially as far as democratization is concerned. The stake here is to boost the scientific character of results in educational research, and therefore its legitimacy and its influence upon educational policies. The authors stress the importance of the historical context of data, the leading part of conceptualization, so that the structural changes of schooling may be grasped, and also the impact of technical measures upon factual knowledge. Finally, the issue of data, a difficult one in that field like in other ones, is illustrated by the analysis of the relation between "ZEP" (…
