By means of the three-dimensional discrete element method, we study long-time evolution toward liquefaction state in granular materials composed spherical particles under multidirectional cyclic shearing at constant volume. Extensive simulations were carried out along 1-D linear, 2-D circular/oval, and 8-like shear paths, system was analyzed terms pore pressure, strain, texture. The macroscopic...

abstract the aim of this study, is to evaluate the effect of loss methods application on run-off volume and hydrograph shape used by hydrologic models. in this research, four loss methods including constant loss (φ index), initial loss-loss rate, scs and constant fraction approach were applied to be evaluated. to do this, clark rainfall-runoff model was applied for 24 storm events from kasilain...

Analysis of the passive pressure-volume filling curve of the left ventricle demonstrates that heart size and ventricular geometry exert major effects on the pressure-volume curve in the absence of changes in intrinsic muscle stiffness. Because the pressure-volume relationship is curvilinear, both quantitative and qualitative comparison of pressure-volume curves from different hearts is difficul...

Isogenic E. coli cells growing in a constant environment display significant variability in growth rates, division sizes, and generation times. The guiding principle appears to be that each cell, during one generation, adds a size increment that is uncorrelated to its birth size. Here, we investigate the mechanisms underlying this "adder" behavior by mapping the chromosome replication cycle to ...

Three activated carbons are synthesized in a rotary reactor at different activation times. The adsorption isotherms of the samples are measured The pore size distribution of the samples is determined using combined Saito and Foley method, BJH method. An average potential function has been determined inside the cylindrical pores. The effect of activation time on the pore size distribution sample...
