Noor Ibrahim Ali Jan from the Materials Engineering Department at the University of Technology received her master's degree on her thesis entitled "Properties of green concrete using recycled materials
The study examined the use of alfalfa powder, fluorescent glass (neon),
Brown glass powder, ash rice husks, sawdust and powder two types as a partial substitute for cement. (11,13,15%) of the weight of cement. The percentage of mixing was used in ordinary concrete (1: 1.5: 3) with a constant ratio between water and cement (W / C = 0.45). ). At the time of processing (7,14,28) days. Under the alternative materials used, nineteen mixing groups were classified. The first mixture is for normal concretes (without alternative materials). The eighteen substrates are for the above materials, all of which have the same range of granular gradient (600-75) micro-meters.
The results showed that a few materials that act as a partial replacement of cement have improved mechanical and physical properties (water absorption properties).

Assist.Prof. Dr Sami Ibrahim Al-Rubaie, Head of the Mining and Extraction Engineering Department at the Department of Production and Minerals Engineering at the University of Technology, participated in the first international conference for pure sciences of Qadisiyah University, which was held on 19 and 20 of November 2017.
Extraction of cadmium from NiCd sent batteries
The conference was attended by researchers from countries such as Belgium, Serbia, Germany, Iran, Bahrain, France, Brazil, India and the United States, as well as participants from various Iraqi universities.


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.
