The coefficient of earth pressure at rest K0 is a state soil variable correlated with relative density Dr. As previously conducted tests could not guarantee zero lateral deformation in the sand specimens, significant errors occurred test results. In this paper, centrifugal model method used to study varying densities. specimens densities are prepared by pluviation, and 50 g-ton force applied. S...

We have used molecular dynamics simulations with coarse-grained and atomistic models to study the lateral pressure profiles in lipid monolayers. We first consider simple oillair and oil/water interfaces, and then proceed to lipid monolayers at air/water and oil/water interfaces. The results are qualitatively similar in both atomistic and coarse-grained models. The lateral pressure profile in a ...
