Reliability and failure mechanism of a slope with non-stationarity and rotated transverse anisotropy in undrained soil strength

, 2021
Natural soils often exhibit rotated transverse anisotropy due to various geological processes (e.g., tectonic movement, filling and soil deposition), and the trend of soil strength usually changes with depth.

The strength characteristics and progressive failure mechanism of soft rock-coal combination samples with consideration given to interface effects

, 2021
The coal-measure rock masses of China's Ordos Basin are mainly composed of typical soft rock with low strength, which bear loads together with the coal seams during coal mining activities.

Effects of foliation on deformation and failure mechanism of silty slates

, 2021
The objective of this study was to investigate the deformation and failure mechanism of silty slates loaded with an angle 0 and 90° between foliation and direction of uniaxial force. For this purpose, mineral composition and microstructure test, uniaxial

Mechanisms of sunscreen failure

Journal of the American Academy of Dermatology, 2001
Sunscreen is used as a primary strategy to prevent sunburn and later skin cancer. However, sunscreen use has paradoxically been associated with the increasing incidence of skin cancer. One explanation for this puzzling observation is sunscreen failure (sunburn in the setting of sunscreen).

Rifamycin antibiotics and the mechanisms of their failure

The Journal of Antibiotics, 2021
Rifamycins are a class of antibiotics that were first discovered in 1957 and are known for their use in treating tuberculosis (TB). Rifamycins exhibit bactericidal activity against many Gram-positive and Gram-negative bacteria by inhibiting RNA polymerase (RNAP); however, resistance is prevalent and the mechanisms range from primary target modification
