The Application of Nanoparticles of Waste Tires in Remediating Boron from Desalinated Water
(2017 , Master Thesis)A waste tire rubber (WTR) collected from the remains discarded tires has exhibited a noteworthy capacity to adsorb Boron. In the current study, the boron adsorption remediation from water at selected pH values, initial ... -
Application of Non-Noble Metal and Cellulose Nanocrystals Modified Date Pits as Novel Adsorbents for Groundwater Treatment
(2023 , Master Thesis)This work was designed to investigate the potential of eliminating lithium (Li) and molybdenum (Mo) ions from groundwater through adsorption. A novel adsorbent was prepared by using agricultural waste, namely date pits. ... -
Assessment of Temporal Variation of Fish Assemblages between Natural and Artificial Reefs
(2021 , Master Thesis)Well-defined coral reefs and patches with high density of fishes were reported in the Arabian Gulf. Due to environmental and anthropogenic disturbances, especially due to coastal development, coral reef cover starts ... -
Biological Control Of Mycotoxigenic Fungi And Associated Mycotoxins By The Application Of Bacterial And Yeast Antifungal Compounds
(2019 , Master Thesis)Mycotoxins are secondary metabolites of mycotoxigenic fungi and are considered as a serious threaten to the life of humans and animals, since some of these mycotoxins are carcinogenic compounds. In this M.Sc research ... -
Cadmium Modulates Expression of Vascular Alpha 1 Adrenoceptors and Aortic Smooth Muscle Cells Phenotype
(2013 , Master Thesis)Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, including Qatar. Hypertension is one of the most common CVDs that contribute to this mortality. Cadmium (Cd) is a well-known pollutant that has ... -
Cadmium, an Environmental Contaminant with a Potential Role In Modulating Cardiac Matrix Metalloproteinases
(2020 , Master Thesis)Cadmium (Cd) is a toxic heavy metal that is found in the environment from both natural and anthropogenic sources. It is a xenobiotic environmental pollutant with no known essential biological functions. Exposure to ... -
