Three MA Theses Approved in College of Science

The College of Science at the United Arab Emirates (UAEU) has approved three MA theses in Chemistry and Biology. The first thesis was entitled, ‘A Study of Y-chromosome STR Markers in the United Arab Emirates Population.’ It was a Molecular Biology paper and by Tareq Ahmed. The study, which is the first of its kind in the UAE and wider Arab world, examined Y-chromosome polymorphism in Arab males in the UAE population. It also looked at the forensic parameters of 27 Y-STR loci in the same population. This included seven rapidly mutating loci (RM Y-STRs) which help to discriminate between closely related and unrelated males. Professor Rabah Iratni, the supervisor of the project, expressed his pleasure at the innovative nature of the study.

Khadega Al Maqdi (MA in Chemistry) presented her thesis on, ‘The Comparative Degradation of Emerging Pollutants Using a Chemical and Enzymatic Approach.’ The study examined the degradation of an antibiotic pollutant (Sulfamethoxazole - SMX), and a model thiazole pollutant (Thioflavin T - ThT) in the presence of either an advanced oxidation process (AOP) - UV + H2O2 - or a peroxidase enzyme system. The degradation was charted spectro-photometrically and via liquid chromatography-mass spectroscopy (LC-MS). The end-products were identified using tandem liquid chromatography-mass spectrometry-mass spectrometry (LC-MS-MS). The results showed, for the first time, that the two remediation approaches produced different sets of intermediates. This suggests that different degradation schemes were operating in both systems (AOP vs. Peroxidase Enzyme System).

MA student, Rubab Ammad (Biology) presented a thesis with the title, ‘A Field Study on Treating Wastewater Using Bioretention and Permeable Pavement Systems.’ This study investigated the performance of two water sensitive urban design systems, the Permeable Pavement and the Bioretention System, in improving the quality of wastewater from fish tanks. Conventionally, these systems are used for storm water treatments, but as UAE is situated in an arid climatic zone and experiences minimal rainfall, the two systems in the study were used to gauge their respective performance. Wastewater from fish tanks came from the Aquaculture Research Center. The outcomes of the study have demarcated the performance capabilities of both systems in treating wastewater and have also provided an insight into system mechanics which can be addressed to enhance both systems.
