Sensory evaluation based on verbal judgments
1999
Studies of the repeatability and the homogeneity of expert panel scores in sensory profiling show that lasting and reliable evaluations of food products are difficult to obtain: strong inter- and intra-individual differences are commonly observed. Our hypothesis is that this variability is due to quantification methods that consist of asking panelists to furnish quantitative values (by attributing a numerical point to perceived intensity) and that using natural language in the form of verbal judgements in a hierarchical tree would allow improving the reliability of sensory evaluations. This hypothesis was tested by comparing a numerical value scale and a specific hierarchical semantic scale…
Influence of chlorophyllaquantification methods in ecological quality indices

Chlorophyll a concentration in aquatic ecosystems is strongly related to the phytoplankton community biomass, the growth of which depends on nutrient availability. Thus, chlorophyll a concentration...
Le petit mobilier en fer des habitats du Hallstatt D-La Tène A : un mobilier sous-exploité
2007
Modern excavations of settlement sites from the end of the First Iron Age and the beginning of the second, together with a re-examination of those undertaken in the past, permit us to better approach some material that has traditionally been neglected as a result of its unpromising aspect: notably some of the iron material. This article will attempt to show the diversity of this material, and some new methods permitting its quantification. The aim is to deepen our understanding of the role and status of this metal in Hallstatt society by a consideration of the material from occupation sites as opposed to funerary monuments.
