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.

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 ...
Symbiotic dinoflagellates associated with corals in Qatar: characterization and physiological response to environmental change
(Biological and Environmental Science, 2017 , Master Thesis)
Studying coral reefs’ responses to environmental and anthropogenic stressors is crucial to
ensure the development of appropriate conservation and restoration programs, especially
in areas such as the Arabian Gulf where ...
Phylogenetic Diversity of Cyanobacteria from Qatar Coastal Waters
(Biological and Environmental Sciences, 2014 , Master Thesis)
Cyanobacteria represent the major microorganism phyla, being diverse and widespread group inhabiting most of the earth's environments. The recent increase of occurrence of toxic cyanobacterial strains in the marine environment ...

Seasonal Changes in Biodiversity and Abundance of Invertebrates in Different Ecological Environments
(Biological and Environmental Sciences, 2013 , Master Thesis)
Biodiversity is a natural quality that must be measured to be understood. It is the measurement of the quantity and diversity of the biota in an area. Each area of the world has its own unique biodiversity as defined by ...
An Integrated Approach to Benthic Habitat Classification of the North Eastern Qatar Marine Zone Using Remote Sensing, Geographic Information System, and in Situ Measurements
(Biological and Environmental Sciences, 2014 , Master Thesis)
A key aspect in the conservation management of the coastal marine zone is mapping the benthic habitat, which is the focus of the work presented in this project. Multispectral Worldview-2 (WV2) satellite data acquired in ...
Disinfection By-Products of Chlorine Dioxide (Chlorite, Chlorate, and Trihalomethanes): Occurence in Drinking Water in Qatar
(Biological and Environmental Sciences, 2014 , Master Thesis)
The occurrence of disinfection by-products (DBPs) of chlorine dioxide (ClO₂) in drinking water, namely: chlorite, chlorate, and THMs as well as the concentration of ClO₂ were investigated. Two hundred ninety four drinking ...
