In the paper we establish some new results depending on the comparative growth properties of composition of entire functions using relative $L^{ast }$-order (relative $L^{ast }$-lower order) as compared to their corresponding left and right factors where $Lequiv Lleft( rright) $ is a slowly changing function.

High density polyethylene is widely used in many applications which deal with slurry because of its high erosion resistance characteristics. Slurry a type erosive wear takes place when stream liquid hits solid body and results this body surface. affected by some parameters as material hardness, impact velocity, impact angle, slurry content, ambient temperature, particle size and particle s...
