Influence of effective stress on gas slippage effect of different rank coals
Fuel, 2021Abstract Gas slippage effect is one of the key factors which would influence gas seepage in coal. The gas permeability of various rank coals under effective stresses are analyzed, and the influence of effective stresses on gas slippage effect of various rank coals and its control mechanism are revealed by the experiment of gas seepage in coal.

Effect of water saturation on gas slippage in tight rocks
Fuel, 2018Abstract Gas slippage phenomenon in single phase gas flow conditions has been extensively investigated. However, only a few researchers have focused on gas slippage in gas/water two-phase flow conditions. Unfortunately, initial water saturation always exists in tight gas reservoirs, and its impact on gas slippage and flow capacity should not be ...

The Effective Radius and Resistance to Slippage
Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014This work reveals that parallel gripper flat-jaw configuration affects grasping effectiveness. An important finding is the fact that object grasp reliability is influenced significantly by gripper's ability to develop high resistance to object rotation in the gripper. The concept of effective torque radius, which increases resistance to object rotation

Macroscopic Evidence of the Effect of Interfacial Slippage on Adhesion
Science, 1995The adhesion strengths of a viscoelastic adhesive were measured on various substrates that were prepared by grafting silanes bearing organic functional groups to silicon wafers. Conventional theories predict that adhesion should be proportional to the surface free energy of the substrate; but adhesion on a fluorocarbon surface was significantly greater

Effect of Interfacial Slippage on Viscoelastic Adhesion
Langmuir, 1997Peeling of a viscoelastic adhesive from a solid substrate poses a wonderful problem of polymer flow. When the adhesive is peeled, it is also stretched in a direction normal to the substrate. The concomitant Poisson contraction creates a pressure gradient and thus induces a shear flow in the adhesive close to the delamination front.

Josephson Effect and Phase Slippage in Superfluids
Japanese Journal of Applied Physics, 1987By operating a miniature two-hole Helmholtz oscillator equipped with a submicron aperture in 4He and 3He superfluid baths, we have been able to observe individual phase slips events as well as characteristic staircase patterns similar to those observed in electrodynamic rf-SQUIDs.

Tread Patterns and the Effect on Basketball Player Slippage
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2020The focus of this study was to investigate the effects that different basketball shoe outsole tread patterns have on the amount of slip and therefore the performance of the individual while undergoing normal basketball transitions. Tread grooves and patterns must exist on the outsole of a basketball shoe to account for the chances of contamination and ...
