The development of novel composite materials of modified roasted date pits using ferrocyanides for the recovery of valuable metal ions from seawater reverse osmosis brine
(Jun- , Master Thesis)In this project, novel composite materials from modified roasted date pits using ferrocyanides were developed and investigated for the recovery of valuable metal ions (Li+ and Sr2+) from seawater reverse osmosis (RO) ... -
The Use of Novel Ionic Liquid and Cellulose Nanocrystals Modified Date Pits as Adsorbents for Groundwater Treatment
(Jun- , Master Thesis)This study aims to investigate the remediation of Li1+, Mo6+, and B3+ from groundwater using an innovative low-cost adsorbent. Agriculturally abundant date pits were modified to be successfully used as an adsorbent. ... -
Impact of Environmental and Anthropogenic Conditions on the Reproductive Cycle of the Pearl Oyster Pinctada Imbricata in Qatar
(Jun- , Master Thesis)To master the aquaculture of pearl oysters Pinctada imbricada, one must master its reproductive cycle. We investigated it through histology, analysis of water physico chemistry and behavior recording on wild oysters sampled ... -
Development of Biosurfactants from Indigenous Hydrocarbon-Degrading Bacteria for Enhancing Remediation of Weathered Oily-Soils and Oil Recovery in Qatar
(Jun- , Master Thesis)Bacterial strains were isolated from highly weathered oil-contaminated sites, identified, and differentiated based on their gene expression with the use of matrix assisted laser desorption ionization-time of flight mass ... -
Development of Functionalized Date Pits Adsorbent for the Removal of Boron, Lithium, and Molybdenum from Groundwater in the State of Qatar
(Jun- , Dissertation)Groundwater (GW) quality deterioration is one of the main water security issues in Qatar. Although the GW in the State of Qatar is not used as drinking water for the public, it is widely used for agricultural, domestic, ... -
Assessment of Temporal Variation of Fish Assemblages between Natural and Artificial Reefs
(Jun- , 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 to ... -
Hydrocarbon Degrading Candidate Bacteria Isolated From Qatar Polluted Soil and Molecular Identification of Key Enzymes Coding Genes
(Jun- , Master Thesis)Sixteen bacterial strains were isolated form contaminated soils and identified as Bacillus subtilis, Bacillus circulans, Burkholderia cepacia, Pseudomonas aeruginosa, Micrococcus luteus, Raoultella ornithinolytica and ... -
Anticancer Activity of Guggulsterone in Multiple Myeloma Cells
(Jun- , Master Thesis)Guggulsterone (GS), a phytosteroid derived from guggul plants' gum resin, has anti-inflammatory and antioxidant properties. Although, the GS is found to have cytotoxic effects in Multiple Myeloma (MM) cells, the mechanisms ... -
Meiobenthic assemblages in some intertidal areas around Qatar, Arabian gulf
(2021 , Professional Masters Project)Sediment core samples were collected in 10 locations around intertidal areas of Qatar to acquire baseline information on meiobenthic density and composition. Temperature, salinity, and pH of interstitial waters were ... -
ASSESSMENT OF ORDERING PRACTICES AT BIOMEDICAL RESEARCH CENTER (BRC)- METABOLIC RESEARCH LABORATORY (MRL)
(2021 , Professional Masters Project)Background: Assessment of the purchasing and ordering process in the Metabolic Research Laboratory (MRL) at the Biomedical Research Center (BRC) at Qatar University (QU) is a critical component of the quality management ... -
Biodiversity of Ant Fauna (Hymenoptera: Formicidae) in Qatar
(2021 , Dissertation)Information on Formicidae of Qatar as well as insect fauna is poorly documented. So far only six species of Formicidae (ants) belonging to five genera have been recorded from Qatar; Brachyponera sennaarensis, Cataglyphis ... -
Linking Soil Chemical Parameters and Arbuscular Mycorrhizal Fungal Communities in Qatar
(2020 , Master Thesis)Much of Qatar’s habitats are characterized by a hyper-arid climate, low rainfall and scarce soil nutrients; all of which combine to create a stress-induced environment for fungal development. Agricultural productivity ... -
Role of Protein Arginine Methyltransferase 5 (PRMT5) in WNT/β--CATENIN proliferative signaling in breast cancer
(2020 , Dissertation)Protein arginine methyltransferase 5 (PRMT5) activity is dysregulated in many aggressive cancers and its enhanced levels are associated with increased tumor growth and survival. In this study, we show that PRMT5 is ... -
Variability in Genomic Patterns of Bacterial Communities Related to Tarmats and Quantification of Hydrocarbon Present in the Tarmats Deposited along the Qatar Coast
(2020 , Master Thesis)Qatar has undergone a rapid transition from a fishing and small agriculture to an economy focused on oil and gas since 1960. Owing to the comparatively large level of oil and gas production, the region has become severely ... -
“Sources and Distribution of Suspended Particulate Matter (SPM) Using Stable Isotopes In The Central Arabian Gulf”
(2020 , Master Thesis)Suspended Particulate matter (SPM) (>0.45µm) plays a significant role in the global carbon cycle. Hence, we measured changes in concentrations of SPM with depth and at distances from shore in the exclusive economic zone ... -
Development of a Novel Polymer-Modified Graphene Oxide Nanocomposites for Controlling Calcium Sulfate Scaling and Biofouling on Reverse Osmosis Membrane: Mechanistic Study
(2020 , Dissertation)Reverse Osmosis (RO) is a promising environment friendly desalination technology for clean water production. However, the performance of RO is getting affected by the mineral scaling and biofouling. During this research, ... -
Uncovering the Epigenetic Contribution of Protein Arginine Methyltransferase 5 (PRMT5) during Zebrafish Cardiomyogenesis
(2020 , Dissertation)The heart develops through an extremely intricate process mediated by a network of transcription factors initiated by key chromatin modification events. Scientist have implicated the protein arginine methyltransferase ... -
Investigation and Biological Control of Toxigenic Fungi and Mycotoxins in Dairy Cattle Feed
(2020 , Master Thesis)Mycotoxins are secondary metabolites synthesized by mycotoxigenic fungi, contaminating human and animal food and feed. Aflatoxin B1 (AFB1) and ochratoxins (OTA) are frequently detected in animal feed products causing ... -
Investigation of the Role of Carbonic Anhydrase in Mineral Formation and Magnesium Incorporation by Bacteria from Qatari Sabkhas and Marine Sediments
(2020 , Master Thesis)Mineral-forming bacteria are of great interest in arid environments specifically. These environments are favorable for enhancing the microbial carbonate deposition that is thought to largely influence the sedimentary ... -
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 ...
