Abstract

Cette Ligne directrice est destinée à évaluer les effets des substances chimiques sur la reproduction des collemboles dans le sol. Folsomia candida,  qui se reproduit par parthénogénèse, est l’espèce recommandée, mais une autre espèce telle que Folsomia Fimetaria, dont la reproduction est sexuée, peut aussi être utilisée si les critères de validité sont remplis. Cette Ligne directrice peut être utilisée pour des substances solubles ou insolubles, mais elle ne s’applique pas aux substances volatiles. L’objectif est de déterminer les effets toxiques de la substance sur la mortalité des adultes et sur le taux de reproduction exprimé respectivement par la CLx et la CEx, ou par les valeurs CSEO/CMEO. Le nombre de concentrations d’essai varie en fonction des effets à mesurer. Pour une approche combinée visant à déterminer les CSEO/CMEO, huit concentrations formant une série géométrique, quatre réplicats pour chaque concentration et huit réplicats témoins sont utilisés. Dans chaque récipient d’essai, 10 juvéniles F. candida (ou 10 males et 10 femelles F. fimetaria) sont placés sur 30 g de sol artificiel modifié OCDE contenant 5 % de matière organique. La durée d’un essai de reproduction définitif est de 4 semaines pour F. candida et de 3 semaines pour F. fimetaria.

Abstract

Soils, rocks and concrete are the principal materials a civil engineer encounters in practice. This book deals with the material analogies, their implications in property characterization, giving attention to similar as well as dissimilar methods in respect of each of these three materials. It provides an integrated, systematic approach for realistic assessment of engineering properties of soils, rocks and concrete. Geotechnical engineers, civil engineers and materials scientists will be interested in this volume.

Abstract

Interpreting Soil Test Results is a practical reference enabling soil scientists, environmental scientists, environmental engineers, land holders and others involved in land management to better understand a range of soil test methods and interpret the results of these tests. It also contains a comprehensive description of the soil properties relevant to many environmental and natural land resource issues and investigations.

Abstract

The Use of Effective Stresses in Unsaturated Soils -In this book, an analytical equation for the effective stress for unsaturated soils is established. This equation requires the knowledge of the superficial area of solids affected by the capillary phenomenon. This e-book demonstrates that the same strength and volume change equations used in saturated soil mechanics can be used for the case of unsaturated soils. In other words, the constitutive models developed for saturated soils can be used for unsaturated materials once the effective stress equation has been defined.
