Such materials as rock and concrete is much lower in tensile strength than in compressive strength and they are broken easily by tensile stress, it is therefore more important to understand the tensile strength reduction of concrete induced by microwave irradiation.

Materials and Methods The crude oil samples were collected directly from the wellhead of each of the four oil wells namely Gilli-Gilli [Gelegele] 1 (GG1), Gilli-Gilli [Gelegele] North (GGN), Ovia 1 Short String (OSS) and Ovia 1 Long String (OLS) at Dubri producing Nigeria onshore locations at Ughoton and Gilli-Gilli [Gelegele], Edo State, Nigeria.
Studies have shown that crude oils are formed during categenesis of sedimentary organic materials which migrate from the rock sources into rock reservoir under the combined effect of temperature and pressure [4].
This suggests that the crude oils under study might have been formed from materials of terrestrial origin.

However, the development of superconducting HGMS technology is limited by the development of rare superconducting materials and auxiliary refrigeration equipment and adiabatic apparatus.
The popularization of low temperature superconducting materials has been affected since maintenance of superconducting state is costly. [9]For this reason, low temperature superconducting magnetic separators can hardly compete with traditional process equipment.
At present, more and more research is conducted on superconducting materials and superconducting theory.

Experimental and methods Experimental materials The experimental materials contained tin-bearing iron ores, pyrite(FeS2), anthracite(C) and high purity nitrogen(N2).
Anthracite was used to solid reducer, and carbon generated combustion reaction when oxygen existed, and CO took mainly part in reducing materials.
High tin content was existed in tin-bearing iron ores, and they should be pretreated to remove tin if directly used as ironmaking materials.
