The Honorable President of the University of Technology, Prof. Dr. Ahmed Mohamed Hassan Al-Ghabban, granted a letter of Acknowledge  to the Asst.  Prof. Dr. Jabbar Hussain Muhammad on of the teaching staff  in the Department of Materials Engineering, for his outstanding efforts in completing and publishing two research papers within Scopus containers, according to book No. 572 S/Aff dated 06/30/2022.

first paper titled

"Natural frequency and critical velocities of heated inclined pinned PP-R pipe conveying fluid"

Abstract
This work treats the transverse vibration for a polypropylene random copolymer (PP-R) pipe, conveying fluid. The pipe was placed at different support angles and subjected to variant temperatures. It was revealed that the thermal effects in the pipe are a very important factor and more significant in comparison with the internal fluid velocity and the inclination angle has a larger impact on vibration characteristics at a higher aspect ratio.
Second paper  titled

"Dynamic response of inclined pipe conveying fluid under thermal effect"

Abstract
This work is aimed at studying the dynamic response of polypropylene random-copolymer (PP-R) pipes caused by fluid flow inside them. The results demonstrate that there is a significant increase in pipe deflection with increasing temperature and aspect ratio. and fluid velocity, while a decrease in the deflection value is observed with an increase in the angle of inclination in the range of 0-90°.
