<p>The effective stress law for the permeability of a limestone is studied experimentally by performing constant head permeability tests in a triaxial cell with different conditions of confining pressure and pore pressure pf.</p>

This paper presents a synthesis of mechanisms related to structure development of surficial heavy clay soils. These clay soils develop specific structural features due to wet/dry cycles and desiccation cracking they undergo during soil "ripening". There is ...

This paper is about the interpretation of microstructures involving quartz and feldspar in metamorphic rocks.
