“Sources and Distribution of Suspended Particulate Matter (SPM) Using Stable Isotopes In The Central Arabian Gulf”
(Environmental Science, 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 ...
Cadmium, an Environmental Contaminant with a Potential Role In Modulating Cardiac Matrix Metalloproteinases
(Environmental Sciences, 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 ...
Investigation and Biological Control of Toxigenic Fungi and Mycotoxins in Dairy Cattle Feed
(Environmental Sciences, 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 ...
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, ...
Linking Soil Chemical Parameters and Arbuscular Mycorrhizal Fungal Communities in Qatar
(Environmental Sciences, 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 ...
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 ...
Initial Assessment of Environmental Microbial Hazards in Doha Restaurants
(Biological and Environmental Sciences, 2017 , Master Thesis)
This study was carried out to assess hygiene conditions, food handling practices, food safety knowledge of food service providers (FSPs), and the microbial quality of food served in different food service establishments ...
Optimizing The Remediation Of Organophosphorus Pesticide Profenofos From Water Using Activated Date Pits: Mechanistic Studies
(Environmental Sciences, 2019 , Master Thesis)
The aim of the study was to examine the efficiency of date pits as an adsorbent to remove the organophosphate pesticide profenofos from wastewater. Various adsorption isotherms models namely Langmuir isotherm, Freundlich ...
Biological Control Of Mycotoxigenic Fungi And Associated Mycotoxins By The Application Of Bacterial And Yeast Antifungal Compounds
(Environmental Sciences, 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 ...
Mobile Epifauna Associated To Artificial Substrates In Offshore Qatari Waters
(Environmental Sciences, 2019 , Master Thesis)
Offshore human-made structures including oil and gas platforms and other energy producing
structures, such as foundations of windfarms, serve as hard substratum supporting diverse marine
communities of invertebrates both ...
