Obtaining the metallic materials route metallurgy powder, the sintering process is preponderant in the final properties of material.
Sintering is a thermodynamic process used for consolidation of ceramic and metallic materials with controlled porosity, empirically it happens around 70 % of the fusion temperature of the material.

Keywords: Natural Rubber, Cup lump, Maturation, Plasticity retention index, Microorganism Abstract Natural rubber is the main raw material in various rubber products.
In the STR 20 standard process, mainly raw cup lump is used, and the microbial populations in the cup lump affect the properties of the raw material during intermediate storage that cannot be avoided.
We screened microorganisms in matured cup lump, and evaluated the key properties determining raw material quality, under various maturation conditions.

Growth of wireless communications systems which requires radio propagation through indoor environments has increasingly demanded that more knowledge regarding how building materials affect the radio channels be searched and added.
Therefore, further studies that focus on transmission and reflection properties of these materials in indoor environments are desirable [11].
