Geocell structures consist of a series of interconnected single cells, made from different polymer materials. The cell walls completely encase the infill material and provide an all-around confinement to the soil. The confinement effect is based on three main mechanisms: active earth pressure within loaded cell, passive earth resistance in the adjacent cells and hoop stresses in the cell walls....

Buckling analysis of thin cylindrical shells is very important due to their production process.  Usually longitudinal and transversal stiffeners are used to increase the buckling stiffness. In this paper, considering a thin cylindrical shell with longitudinal and transversal ribs subjected to axial force and lateral pressure, the influence of different aspect of axial force to lateral pressure ...

Abstract Due to their multiple uses and structural challenges they outline during normal circumstances seismic events, retaining walls constitute an important concern for civil engineers. Design of these structures requires accurate determination lateral earth pressure under various conditions. Considering the dynamical action excitation, total cohesion-less soil backfills is often estimated by...

The initiation of furrow formation is disrupted when microtubule elongation to the cell surface is inhibited either by promoting microtubule disassembly with hydrostatic pressure or by stabilizing the mitotic astral microtubules with taxol. The pressure studies confirmed Rappaport's earlier observation that stimulation of furrow formation is produced by a pair of asters and does not require chr...
