A semi-empirical model to predict excess pore pressure generation in partially saturated sand [PDF]
Past studies revealed that excess pore pressure generation due to cyclic loading is highly governed by induced strains, volumetric deformation potential of soil, number of cycles, and bulk stiffness of pore fluid.

A Fluid-Solid Coupling Mathematical Model of Methane Driven by Water in Porous Coal
The existence of the water-driven-methane effect in gassy coal has been verified by field tests and laboratory experiments. However, a water-driven-methane mathematical model that considers methane adsorption and desorption has not yet been established ...

Mechanism of pore pressure time lag for saturated clays
Time lag of pore pressure often occurs during oedometer consolidation of saturated clays. After applying loading, the pore pressure measured at the base of specimens increases up to the maximum and then decreases with the increase in consolidation time ...

ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Minimum stress and pore fluid pressure in sedimentary basins [PDF]
Leak-off pressures (LOPs) recorded during leak-off tests (LOTs) conducted down boreholes are often used to estimate the magnitude of the minimum stress (usually assumed to be horizontal – S(_h)) in the subsurface.
