An analysis of inner cone cracks in brittle solids subject to cyclic indentation in liquid is presented. These inner cone cracks, so named because they form well within the maximum contact circle, are postulated to be driven by a hydraulic pumping mechanism. Unlike their more traditional outer cone crack counterparts, inner cones do not appear in monotonic loading or even cyclic loading in the ...

[1] Spatial variability of hydraulic aquifer parameters causes meandering, squeezing, stretching, and enhanced mixing of steady state plumes in concentrated hot-spots of mixing. Because the exact spatial distribution of hydraulic parameters is uncertain, the spatial distribution of enhanced mixing rates is also uncertain. We discuss how relevant the resulting uncertainty of mixing rates is for ...

Modularity is a powerful property for analyzing the behavior of a system on the basis of the behavior of its components. According to this property, any two components maintain their behavior unchanged upon interconnection. Is modularity a natural property of bio-molecular networks? In this review, we summarize recent theoretical and experimental results that demonstrate that the answer to this...

Lime soil treatment is a chemical process in which lime (quicklime, hydrated or slurry) mixed with the place subgrade and reaction takes place. The reacts clay particles to create cementitious matrix. design of landfill base liners including layer as fluid barrier (i.e. water-resistant impervious layer) requires neat engineering approach considering, particular, consolidation behavior well hydr...
