Umbilical and Inguinal Hernia Symptoms and Treatment. A hernia occurs when an organ inside the body (usually the intestine or bladder) pushes through an opening in the abdominal wall. Learn how to spot the signs of two common hernias and when to seek treatment. Facebook.
Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: 1  Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering)  Cementing by Fe2O3, CaCO3, NaCl, etc.
Soil liquefaction describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.his is because a loose soil has the tendency to compress when sheared, generating large excess porewater pressure as load is transferred from the soil skeleton to adjacent pore water during undrained loading. As pore water pressure rises a progressive loss of strength of the soil occurs as effective stress is reduced.
