He has been, and is, a very lively and active figure in the growth of quality materials science at Roorkee.
Unusually among scientists and technologists, his interests and work extend well beyond materials science.
His varied contributions to metallurgy and materials science are briefly touched upon, their origin and development described.
Materials Science and Engineering at its core is an interdisciplinary subject which embodies fundamental knowledge from the great disciplines of Science and Engineering.
Thomas Wohlbier, Director, Trans Tech Publications for coming forward to publish this special volume in Materials Science Forum.

All materials were considered homogeneous, isotropic and having linear elasticity.
Materials and method For the study of the removable partial denture’s stresses and displacement distribution was used FEA.
The denture was scaned in Dental View radiology center and the tomographic images were combined with the constant mechanical and thermal properties of the materials and were used to create the 3D model (Fig.1).
All materials were considered homogeneous, isotropic and having linear elasticity.

The reinforced materials used in the splice can enhance soil hardening and help establish soil arching effect under which the settlement of subgrade is well controlled.
It is for this reason that this research program is conducted, on the basis of previous researches, to find out the mechanism and pattern of subgrade damage as caused by water wetting to the widened roads in collapsible loess areas Model test design Test materials Loess was used in the test as subgrade (new and old) filling, physical properties of which are shown in Table 1.

Mining Ecological Safety Problems Mineral resources are the important material base of human society development.
The rapid development and utilization of mineral resources has provided the important material guarantee for social economy fast and steady development.
In addition, the reputation of "the home of non-ferrous metals" also only means the supply of raw materials, and don’t combined non-ferrous metal advantages with metallurgy, materials of industry development.
