Abstract:

The study aimed to prepare a composite material containing different weight ratios of magnesium for use in the treatment of maxillary bone decay. A ceramic material with improved mechanical properties consisting of 70 wt.% hydroxyapatite and 30 wt.% cordierite ceramic is manufactured, sintered at 1100°C and then used as a reinforcement phase within a polycaprolactone matrix. Magnesium was added in proportions of 1, 3, 5, 7 wt.% to the composite material for the purpose of evaluating the effect of magnesium on biological performance in vivo and in vitro. The results proved that the presence of magnesium element by 5 wt.% led to an improvement in all biological properties in terms of degradation rate, bioactivity, cell viability, cell attachment in addition to the formation of new bone after 45 days of transplantation, and this is proven by the results of the histological analysis of the bone sample.

After the discussion committee recorded its observations on the thesis, which were divided between explanation, correction, and the student’s defense of her thesis.

  At the end of the discussion, the committee decided to evaluate the thesis and decided to grant the student a doctorate degree with a pass grade.

 The Department of Materials Engineering at the University of Technology granted a doctorate degree to the student Israa Karim Hamid/Department of Materials Engineering/University of Technology for her tagged thesis:

Abstract:

The study aimed to recycle plastic waste (water bottles) to manufacture sustainable partition blocks. The waste was recycled mechanically and chemically. The sample manufacturing process included two steps. The first was mixing recycled waste with bitumen to produce improved bitumen. As for the second step, mixing this improved bitumen at a rate not exceeding  20% with sand and gravel, at a rate not exceeding 80%, in different grades...  Among the most prominent results that emerged with us.

There are very moderate compressive mechanical properties, in addition to high sound insulation due to the small plastic particles that have penetrated the mixture, increasing the amount of insulation, in addition to high moisture insulation, since plastic and bitumen have very high insulation 

After the discussion committee recorded its observations on the thesis, which were divided between explanation and correction, and the student’s defense of her thesis, and the end of the discussion, the committee sat down to evaluate the thesis, and decided to grant the student a doctoral degree with a pass grade.

A meeting was held between L. Iman Kazem/Educational and Psychological Guidance Unit in the Department of Materials Engineering with the students of the second stage on Tuesday, 31/10/2023, at twelve o’clock in the morning in Hall No. (2) to learn and see the problems and difficulties they face during their studies, determine their causes, and find appropriate solutions. In cooperation with the department head and its teaching staff.

The Department of Materials Engineering at the University of Technology awarded a doctoral degree to the student, Samer Karim Turki, Department of Materials Engineering / University of Technology for her thesis titled
