Based on the directives of the Presidency of the University of Technology in general, and the Department of Chemical Engineering in particular in activating the scientific visits of students during the current academic year 2017/2018, the summer training committee organized a scientific visit to the students to the headquarters of the Central Refineries Company (Dura Refinery) under the supervision of faculty members: Assist.Prof. Dr. Khalid Hamed and Assist.Prof. Dr. Adel Sharif and the Senior chemical. Wasan Sami.

The head of the department Assist.Prof. Dr. Jamal Al-Rubaie said: The purpose of the visit is to link the theoretical study with practical application and clarify some practical applications of chemical engineering in the field of oil industries.

A group of specialized engineers in the refinery explained the stages of refining, the water treatment unit in the refinery, the identification of measuring devices and all control equipment, how they work and answering all the students' questions. 

Prof. Dr. Salim Khalifa Kazem from Control and Systems Engineering Department  at the University of Technology published a joint scientific research with a group of researchers entitled "Numerical verification of the effect of vibrations induced by blood flow on artificial heart valve diffusion through the use of liquid structure reaction structure Scoopas Journal International under Thomson Reuters.

Research focuses on surgeries to replace the most common artificial heart valves often used due to failure of the artificial heart valve. Determining the cause of failure and finding appropriate solutions requires deep knowledge about the behavior of the artificial heart valve and operation. The causes of the valve failure are related to the patient's body and the design of the valve. With human body with blood flow dynamics and materials used to manufacture valve. When the blood flows through the arteries and valves, blood activates forces in the components of the valve, causing induced vibrations caused by the flow, which may lead to valve damage. In this study, fluid structure interaction techniques were used to analyze fluid dynamics to investigate the effects of simulated vibrations To obtain optimal design for shear stress, shear stress was calculated from the artificial heart valve contact pin and compared with the shear stress of the contact pin in the literature. In the Reynolds number of 250, excitation frequencies increased from 94.24 rad / s to 126.9 rad / s, resulting in a 75% increase in shear stress values ​​in the pin-contact valve at a completely closed angle of 85 °. The increase in frequency may cause a ringing phenomenon that will cause damage to artificial heart valve components, and then, the blood components will also be damaged, causing increased blood clotting occurs downstream of the artificial heart valve.

Posted by Assist.Prof.Dr Safanah Madheher Raafat from the Department of Control and Systems Engineering at the University of Technology, conducted a scientific research entitled "Improving the Performance of a Controlling System for the Collective Radio Detector by the Optimal Particle Mobility Algorithm" in the Engineering Journal of Baghdad University.

The researcher who completed his research in collaboration with Assist.Prof.Dr. Ahmed Madheher Hassan and researcher Karar Ghalib describes the application of the compatibility improvement of the wireless sensor network. The compatibility algorithm is usually performed for a specific number of steps for the structure of the graph. However, Or other parameters of the graph structure; as a result, the error and correctness will be applied to the best number of steps, and the implementation of the smart optimization algorithm will effectively help to obtain the best number of steps if the performance of the compatibility algorithm is significantly improved by using the particle optimization method As an analytical study, a different number of nodes was taken into account in the grid for a random number of graph structure. The results obtained from the simulation showed a significant decrease in the number of steps and energy consumption. The number of steps was reduced to about 40 steps using the optimization method of a different number of nodes Specific network.

The Ministry of Planning, the Central Organization for Standardization and Quality Control granted a patent for two professors from the Materials Engineering Department at the University of Technology, Asst.Prof.Dr.Alaa Al-Din Abdul Hamid and Asst.Prof.Dr. Farhad Mohamed Osman for manufacturing nanocides by chemical thermal spraying method and including mortar in construction applications.The patent included the production of nano crystalline powders by chemical spraying technology, single and bicarbonate oxides powders prepared using mineral salts and the use of titanium and copper sulphate for the production of TiO2 and CuO respectively at 750 ± 5 ° C and the use of different moles , 0.1, 1). Tests were carried out on the powder including x-ray diffraction, electron microscopy, particle size analysis, and density testing. This method is unique to prepare an economic nanoparticle. The amount of prepared material (30 ± 1 g) was 100 g of basic salt. The production efficiency of TiO2 was 87% and the efficiency of CuO was 80%, making it economical and feasible for industrial use.

Professor Salim Khalifah Kazem of the Department of Control and Systems Engineering at the University of Technology published a joint scientific paper, published in the journal of physics, in the Scopas Thomson Reuters classification:

 (Numerical investigation of the effect of aortic root engineering on internal flow stresses on the mechanical heart valve structure of the binary diffuser).

The researchers found that the stresses in BMHV may be caused by pulse blood flow in the valve failure. In this study, Von Mesis stress is computed and compared to BMHV, which is placed in two types of aortic root geometry, which is the aortic root with non-sinuses Replicas and with identical sinuses, at different physiological blood flow rates.

The researcher found that the von Mesis strain when BMHV was placed in the aortic root with asymmetric sinuses up to 47% higher than BMHV in the aortic root with identical sinuses under the same physiological conditions. The velocity vectors were observed to be high and then lead to increased stress of von Mesis to BMHV and placed in the aortic root with asymmetric sinuses that can lead to valve failure.
