Abstract
The micromechanical behaviour of basalt ballast particles was studied by subjecting them to normal (N) and tangential loading (T) under various loads. It is observed that the natural ballast particle pairs subjected to normal loading have a softer response than that predicted by Hertz (1882) theory. The coefficient of interparticle friction (μ), measured during monotonic shearing, is about 0.5-0.6, while during cyclic loading, μ was found to stabilise around 0.65-0.85 after about 30 cycles. The value of μ was not affected by the normal load or the loading rate. Roughness, measured before and after testing, was found to change with loading, attributed to deformation of the asperities

Democracy, Like Revolution, is Unattainable Without Women
No full textThe biggest challenge facing women in Arab Spring countries is transforming their leadership and attendant influence during the revolutions into high-level governance positions, both elected and appointed, after the revolutions.
To achieve this goal, reform efforts should include: 1) amending election laws to increase the proportion of women represented at the local, state, and national levels; 2) increasing high-level employment opportunities; and 3) using public education to highlight the role of women and counter perceptions of traditional gender roles.Peer reviewe
