Scientists discover a 'semi-infinite
' supply of rare precious metals on a remote island off the coast of Japan
The research goes as far as to claim the large deposit "has the potential to supply these metals on a semi-infinite
basis to the world".
A Japanese study published last week revealed an estimated 16 million tons of rare earths, enough to feed global demand on a "semi-infinite
" basis, with deposits to last hundreds of years.
One known nonlinear differential equation defined on a semi-infinite
domain is the so-called Blasius equation which appeared in the literature in 1908 .
The aim of the present work is first to investigate the elastic field of an inclined TD piercing the free surface of any anisotropic, semi-infinite
These equations are applied in many areas  such as reaction-diffusion problems in small cells , theory of elasticity, heat conductions, hydrodynamics, stereology , the radiation of heat from semi-infinite
solids , and other applications.
The effect of tail void grouting pressure on the surrounding soil is simplified as an expansion problem of the cylindrical cavity in semi-infinite
Although Hertz contact model is frequently used to interpret the experimental data obtained by AFM indentation, one of its main assumptions, that is, treating indented cell as semi-infinite
space, might be contradicted by the film morphology of cells after being removed from their native environment [6,7].
Therefore, by assuming the prearranged protective coal pillars in the SBBM working face, the backfill body and (m - 1) bed rock as independent springs, and the entity coal in the right part as semi-infinite
elastic foundation, the mth rock beam can be treated as a semi-infinite
The second series was executed at the same temperature ([T.sub.M] = 170[degrees]C) but with [t.sub.C,b] to determine the influence of [t.sub.C] and to test the applicability of the semi-infinite
