Pakistani Army infiltrators had set off a small-scale war in the Kargil area of Kashmir after penetrating along a 150-mile front, at heights up to 18,000 feet.
In contrast, under nitrogen or argon, the infiltrant firstly penetrates along the surface before filling the inside.
Once this film was removed, carburization occurred and free C atoms involved during cracking of ethylene easily penetrated along austenitic grain boundaries.
It is concluded that a thin film of concentrated solution is formed at dry-out which penetrates along the tube wall beyond the point at which tube wall temperature starts to rise.
The PAM chains propagated, penetrated along the pores, and finally reached the surface without irradiation.
Where, precipitation is high and weathering processes penetrate deeply along fracture systems, the granite and gneiss commonly have been eroded down to low-lying areas (Dappah and Gyau-Boakye 2000).
Although a daughter species may penetrate farther along the fracture than its parent species when a constant-concentration boundary condition is applied, our results indicate that all species retain the same transport speed in the fracture if a pulse of the first species is released into the fracture.
When a face core interface crack approaches a tri-material wedge, as it may happen at a sandwich core junction, two options exist for further crack advance; one is for the interface crack to penetrate the wedge along the face core interface, and the second is deflection along the core junction interface.
Actually, the high-porosity and permeability of hyaloclastites implies high liquid fluxes; this water is necessarily in contact with the edges of low-porosity basaltic flow units (but can also penetrate to them along the fractures).
In fact, for a fault that is initially nearly-impermeable, the only possibility of a larger fault slip event would be opening by hydraulic fracturing; this would allow pressure to penetrate the matrix along the fault and to reduce the frictional strength over a sufficiently large fault surface patch.
