Geotechnical hazards such as debris flows, rock falls in slopes, collapse, and rockburst underground mining or caverns are tightly correlated to the mechanical behavior of natural mass stability. Strength failure mode governed by presented fissures. In this paper, samples containing T-shaped fissures with different geometry were prepared rock-like materials tested under varying uniaxial cyclic ...

Active tectonic movement and frequent ground fissure disasters occur in the Kenya Rift Valley. Ground fissures are often exposed to surface after rainfall, resulting huge economic losses. We conducted a field geological survey exploratory trenching order identify developmental characteristics of The were found be connected with concealed bedrock fissures, which is typical characteristic fissure...

The conditions for crack nucleation under impact loading were investigated systematically for four glasses which differ in their chemical composition, hardness and material density. Edge-on impact experiments were carried out with blunt steel cylinders within the velocity range from 20 m/s to 1000 m/s. The propagation of shock waves, of primary and secondary cracks and crack systems and the gro...

Lateral sphincterotomy diminishes internal anal sphincter hypertonia and thereby reduces anal canal pressure. This improves anal mucosal blood flow and promotes the healing of anal fissures. However, sphincterotomy can be associated with long term disturbances of sphincter function. The optimal treatment for an anal fissure is to induce a temporary reduction of anal canal resting pressure to al...

careful antemortem examination and interpretation of findings, assisted by goodclinical records, do much to throw light on the nature of vertical fissure in cattle. during aneight month period of investigation, 13 (3.2%) lame cows with vertical fissure out of 52holstein cows with different claw fissures were selected for clinical and gross pathologicalpurposes in a commercial dairy farm with 40...
