SCREENING, CHARACTERIZATION AND APPLICATIONS OF ENDOPHYTES FROM QATARI HALOPHYTES
(Biological and Environmental Sciences, 2024 , Dissertation)
Saline soil poses a significant challenge for plant growth in arid and semi-arid regions. The harsh climatic and environmental conditions in Qatar and the Gulf region have led to highly saline soil, severely limiting crop ...
CHARACTERIZATION OF QATAR COASTAL BIOFOULING CHALLENGE AND ENVIRONMENTAL INFLUENCES
(Biological and Environmental Sciences, 2024 , Master Thesis)
This research explored the spatial and seasonal variabilities in biofouling challenges at Doha and Ruwais ports in Qatar, using panel deployments under different environmental conditions. Results indicated significant ...
INVESTIGATION AND PRODUCTION OF BIOINSECTICIDES BASED ON NEWLY BACILLUS THURINGIENSIS STRAINS ISOLATED FROM QATAR FOR THE DEVELOPMENT OF A BIOLOGICAL AGRICULTURE AND SAFE FOOD PRODUCTION IN QATAR
(Biological and Environmental Sciences, 2024 , Master Thesis)
Bacillus thuringiensis produces parasporal crystals responsible of their insecticidal activity against specific insect orders. Eight newly isolated Bt strains produce different parasporal crystal and have several genetic ...
APPLICATION OF BIOCHAR PRODUCED FROM PROSOPIS JULIFLORA PODS FOR THE REMOVAL OF LEAD AND NICKEL FROM ARTIFICIALLY CONTAMINATED SOIL AND ENHANCING TOMATO GROWTH
(Environmental Sciences, 2023 , Master Thesis)
The utilization of biochar is considered an environmentally friendly and cost-effective remediation method. In this regard, the application of biochar produced from Prosopis juliflora pods seems to be potentially effective ...
IMPACTS ASSESSMENT OF DESALINATION BRINE DISCHARGE ON THE MARINE MICROBIAL BIODIVERSITY: A METAGENOMIC APPROACH
(Environmental Sciences, 2022 , Master Thesis)
Being a hotspot of desalination, the health of the marine ecosystem of the Arabian Gulf is facing a serious threat. Many studies are suggesting that desalination activities could potentially harm the marine life, however, ...
Investigation of the Role of Carbonic Anhydrase in Mineral Formation and Magnesium Incorporation by Bacteria from Qatari Sabkhas and Marine Sediments
(Biological and Environmental Science, 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 ...
Prospects of Biocrude Production Potential from Local Diatom
(Environmental Sciences, 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, ...
Heavy Metals Hyperaccumulation and the Role of Stress-Induced Proteins in Phytoremediation Mechanism in Selected Qatari Plants
(Biological and Environmental Science, 2020 , Dissertation)
Progressive pollution of the environment by trace and heavy metals pose a significant risk and causes diverse human diseases. Current world initiatives to remove these toxic substances from the environment are costly and ...
ISOLATION OF ENDOGENOUS LACTIC ACID BACTERIA AND DEVELOPMENT OF SILAGE OF PALM TREES LEAVES FOR LIVESTOCK IN QATAR
(Environmental Sciences, 2022 , Master Thesis)
In Qatar, there are relatively low agricultural by-products available, mainly from palm trees for feeding livestock. Preservation of palm leaves is a problem due to harsh environmental conditions. Ensiling palm leaves with ...
Development of a Novel Polymer-Modified Graphene Oxide Nanocomposites for Controlling Calcium Sulfate Scaling and Biofouling on Reverse Osmosis Membrane: Mechanistic Study
(Biological and Environmental Sciences, 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, ...
