Anticancer Activity of Guggulsterone in Multiple Myeloma Cells
(2021 , 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 ... -
Development of Functionalized Date Pits Adsorbent for the Removal of Boron, Lithium, and Molybdenum from Groundwater in the State of Qatar
(2021 , 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, ... -
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
(2021 , 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
(2021 , 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. Chemical ... -
Development of Biosurfactants from Indigenous Hydrocarbon-Degrading Bacteria for Enhancing Remediation of Weathered Oily-Soils and Oil Recovery in Qatar
(2021 , 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 ... -
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 ... -
Prospects of Biocrude Production Potential from Local Diatom
(2020 , Master Thesis)A marine diatom Nitzchia reversa was grown in 5 sq. m open raceway pond (10 cm culture depth, 500 L culture volume) in the Qatari desert environment. After 7 days of growth, the final biomass density reached 0.52 g/L, ... -
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, ... -
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 ... -
