For pillar assessment, mine-pillar interaction curves can be constructed using a double spring analogy.
As the pillar width reduces, the interaction effects becomes more evident.
The overburden depth is responsible for the overall level of stress, but pillar design, multiple seam interactions, and/or mining activity can concentrate stresses in distinct locations.
The enhanced catalytic stability seems to be attributable to the lower mobility of the Al2O3 pillar which formed stronger interactions with the mesoporous Co3O4 inner surfaces.
Design concepts, that include lengths and densities, have evolved from basic dead load calculations to complex interactions with pillar yielding, effective roof spans, and lateral shifting of immediate roof strata.
The key factors determining the magnetic properties of the films are shown to be the aspect ratio of individual pillars and magnetostatic interactions between neighboring pillars.
This paper presents the development of conceptual single-degree-of-freedom models, which are used to derive equations for estimating displacements and stresses for ground-support interaction problems encountered in pillars in room-and-pillar mining (natural support system), and liners for circular vertical shafts (artificial support systems).
Weaving hydrogen bond ribbons with polar and apolar stabilizing pillars as well as stacking interaction of phenyl rings resulting sixfold phenyl embraces interpenetrating with the polar networks were found.
From signal transduction cascades to enzymatic activation, from antibody-antigen recognition to cellular trafficking, direct noncovalent protein-protein interactions are the central pillar supporting most of biological functional activity on the molecular level [1].
The free market, Greenspan told the graduating seniors, is a pillar of civilization which "presupposes the productive interaction of people engaged in the division of labor, driven -- I cannot resist the jargon -- by economic comparative advantage.
While the gold nanoparticles can be functionalized with different molecules, the hydrogel base of the pillars provides a protein-resistant interface, restricting unwanted interaction with biological material.
