Impact of Environmental and Anthropogenic Conditions on the Reproductive Cycle of the Pearl Oyster Pinctada Imbricata in Qatar
(Environmental Sciences, 2021 , 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 ...
INFLUENCE OF ARBUSCULAR MYCORRHIZAL FUNGI (AMF) ISOLATED FROM ARID ZONES ON PLANT GROWTH, PROTEIN CONCENTRATIONS AND RESPONSE TO SALINITY CONDITIONS IN ALFALFA (MEDICAGO SATIVA)
(Environmental Sciences, 2022 , Dissertation)
The present study is aimed to isolate native effective species of arbuscular mycorrhizal fungi from the Qatari environment and to subject these isolates for evaluation to support the growth of Medicago sativa under saline ...
EFFECTS OF ACTIVE PHYTOCHEMICALS OF PROSOPIS JULIFLORA AS ANTI-SPOILING AGENTS OF POSTHARVEST FRUITS
(Environmental Sciences, 2022 , Master Thesis)
Global increase in food demand has made the fresh produce spoilage a worldwide concern. Adverse effects of commercial spoilage control agents on human health and on the environment are major public concern. In this study, ...
Biodiversity of Ant Fauna (Hymenoptera: Formicidae) in Qatar
(Biological and Environmental Science, 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 ...
Development of Biosurfactants from Indigenous Hydrocarbon-Degrading Bacteria for Enhancing Remediation of Weathered Oily-Soils and Oil Recovery in Qatar
(Environmental Sciences, 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 ...
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
(Environmental Sciences, 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) ...
ANALYSIS OF HYDROLOGICAL AND CLIMATIC FACTORS ASSOCIATED WITH ALGAL BLOOMS BASED ON REMOTE SENSING PRODUCTS AROUND THE COASTAL REGION IN THE ARABIAN GULF
(Biological and Environmental Sciences, 2024 , Master Thesis)
Algal Blooms (ABs) are a global ecological disaster threatening aquatic ecosystems, human health, and economics. In the Arabian Gulf, monitoring and early warning systems are needed due to a lack of in-situ data. This study ...
Application of Non-Noble Metal and Cellulose Nanocrystals Modified Date Pits as Novel Adsorbents for Groundwater Treatment
(Biological and Environmental Sciences, 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. ...
Novel approach in treating industrial wastewater using metal-organic framework nanoparticles impregnated with biosurfactants.
(Biological and Environmental Sciences, 2024 , Dissertation)
Arabian Gulf countries including Qatar are amongst the main oil and gas (O&G) producers globally. A huge amount of water is used during the upstream and downstream processes of oil and gas refiners. As a result, a large ...
The Use of Novel Ionic Liquid and Cellulose Nanocrystals Modified Date Pits as Adsorbents for Groundwater Treatment
(Environmental Sciences, 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 ...
