“…The purpose of this paper is to understand how income inequality is associated with economic growth in OECD regions and whether the degree and type of urban concentration affects this relationship. Both income inequality and urban concentration can be seen as patterns of resource allocation that are particularly interlinked at the regional level. …”

“…Large-scale sediment transport models for example require as input the settling velocity of particles. In concentrated areas, this velocity becomes a function of the particles’ concentration and particle-particle interactions lead to the creation of larger particles, called flocs. …”

“…La CE50 et d’autres concentrations efficaces sont calculées à partir des courbes du pourcentage d’inhibition en fonction de la concentration des produits chimiques d’essai, ou, le plus souvent, de son logarithme…”

“…The toxic effect of the test chemical on embryo numbers is expressed as ECX by fitting an appropriate regression model in order to estimate the concentration that would cause x % reduction in embryo numbers or alternatively as the No Observed Effect Concentration and Lowest Observed Effect Concentration (NOEC/LOEC) value (2)…”

“…Alternativement, les données peuvent être comparées aux valeurs témoins afin de déterminer la concentration minimale avec effet observé (CMEO) et, de là, la concentration (maximale) sans effet observé (CSEO)…”

“…On the basis of kinetic measurements the kinetics was described and options for process intensification, specially the reduction of the hydrogen concentration, was demonstrated…”

“…This 2005 edition of OECD's periodic review of the Euro Area economy systematically reviews economic developments and makes policy recommendations. This issue concentrates on growth performance and resilience. The first chapter presents an overview of developments and challenges. …”

“…The test is designed for the determination of the following endpoints LC50 (median Lethal Concentration) and the LDD50 (median Lethal Dietary Dose) values after 10 days of exposure, and NOEC (No Observed Effect Concentration) and NOEDD (No Observed Effect Dietary Dose)…”

“…The review shows that there is little evidence in support of the Schumpeterian hypothesis that market power and large firms stimulate innovations: R&D spending seems to rise more or less proportionally with firm size after a certain threshold level has been passed, and there is little evidence of a positive relationship between R&D intensity and concentration in general. However, positive linkages between concentration/size and innovative activity can occur when certain conditions are met, including high sunk costs per individual project, economies of scale and scope in the production of innovation rents. …”

“…At least three analysable concentrations of the test substance should be used. At each concentration duplicate cultures should normally be used. …”

“…The share of exports concentrated in the 20 leading firms has declined steeply over the last decade, reflecting the dynamism of the small- and medium-scale firm sector. …”

“…It starts with an analysis of the rather elusive concept of JV, encompassing both concentrative JVs (subject to merger control) and non-concentrative JVs. …”

“…Des enchytrées adultes sont exposés à une gamme de concentrations de la substance d'essai mélangée à un sol artificiel. …”

“…Des enchytrées adultes sont exposés à une gamme de concentrations de la substance d'essai mélangée à un sol artificiel. …”

“…To predict the phototoxic potential, the concentration responses obtained in the presence and in the absence of irradiation are compared, usually at the IC50 level, i.e., the concentration reducing cell viability to 50 % compared to the untreated controls. …”

“…Dans le milieu d’Andrew modifié les cultures de Myriophyllum spicatum sont exposées à au moins 5 concentrations différentes du produit chimique d’essai pendant 14 jours. …”

“…EC10, EC50) ou la concentration pour laquelle aucun effet n’est observé (NOEC). …”

“…Il est également possible d’exprimer l’effet toxique du produit chimique testé par la concentration sans effet observé et la concentration minimale avec effet observé (CSEO/CMEO). …”

“…La concentration maximum d'essai recommandée est de 1000 ppm. …”
