Effects of initial stress anisotropy on the onset of undrained instability for Guamo sand

Revista Facultad de Ingeniería Universidad de Antioquia, 2022
Undrained instability is a failure mode that has been observed in many sandy slopes. However, the highly anisotropic stress states caused by the geometry of the slope have not been duly considered from the experimental point of view.

Impact of Land use on soil quality: Insights from the forest-savannah transition zone of Ghana

Heliyon
Land use changes have a profound impact on soil fertility and agricultural production systems in the Forest-Savannah Transition Zone (FSTZ) of Ghana. Soil erosion and shortened fallow periods exacerbate soil fertility loss, further degrading soil quality.

CLASSIFICATION OF SOILS

Aslib Proceedings, 1962
From the first emergence of civilizations based on agriculture, variations in the nature and productive capacity of the soil were recognized by farmers, and names, usually based on colour or texture, were given to distinctive varieties. In modern times the connection between soils and the rocks which provide their parent materials was generally ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
