Prediction of maximum dry unit weight and optimum moisture content for coarse-grained lateritic soils

Optimum Moisture Content, and Permeability of Sandy Soils

In this paper a concept of mean particle size and size factor is presented and an attempt is made to relate the coefficient of permeability with mean particle size, keeping in view the optimum moisture content and maximum dry density. The particle size distribution has a marked impact on the coefficient of permeability. The mean particle size and the size factor can be found out from the gradat...

اثر رس‌های فیبری و املاح بر سرشتی‌های مهندسی خاک‌های نواحی خشک

In Iran, a large extent of the soils and water are facing with salinity; so the geotechnical properties of arid and saline soils are important for engineering design. In this study, the effects of salinity on geotechnical properties of fine-grained and coarse-grained soils containing fibrous clay minerals have been studied. The results showed that salinity was mostly a flocculated agent in fine...

Coarse-Grained Prediction of RNA Loop Structures

One of the key issues in the theoretical prediction of RNA folding is the prediction of loop structure from the sequence. RNA loop free energies are dependent on the loop sequence content. However, most current models account only for the loop length-dependence. The previously developed "Vfold" model (a coarse-grained RNA folding model) provides an effective method to generate the complete ense...

Determination of Hydraulic Conductivity Based on (Soil) - Moisture Content of Fine Grained Soils

Coarse-Grained Potential Model for Structural Prediction of Confined Water.

We propose a coarse-grained potential model to predict the concentration and potential profiles of confined water. In this model, we represent one water molecule with one coarse-grained bead, such that the interactions between the coarse-grained beads are given by isotropic two-body potentials. Due to the inherent inhomogeneity of the confined water microstructure, we find that a single spatial...
