Investigating The Mass Mortality Induced Factors Of Pearl Oyster (Pinctada Radiata) At Abu Dhabi Pearls Farm, Uae, Hamad Ahmed Almansoori
Investigating The Mass Mortality Induced Factors Of Pearl Oyster (Pinctada Radiata) At Abu Dhabi Pearls Farm, Uae, Hamad Ahmed Almansoori
Theses
The aquaculture of shellfish plays a crucial role in enhancing maritime environments by mitigating algal blooms and improving water quality through the filtration of organic matter, nutrients, and bacteria. This study investigated the environmental factors influencing oyster (Pinctada radiata) mortalities through a comprehensive analysis of water quality in Al Mirfa and Al Mughirah farming sites of Abu Dhabi (UAE), from February 2021 to February 2022. To reach such understanding of the main factors led to mass mortalities of cultivated oysters, different monthly sampling and both chemical and biological analyses of the farm water, sediments as well as for both living …
Biohydrogen Production Of A Co-Culture Consisting Of Halophytic Cyanobacterium Phormidium Keutzingianum And Activated Sludge Bacteria Using Different Exogenous Carbon Substrates And Salt Concentrations, Maitha Mohammed Al Nuaimi
Biohydrogen Production Of A Co-Culture Consisting Of Halophytic Cyanobacterium Phormidium Keutzingianum And Activated Sludge Bacteria Using Different Exogenous Carbon Substrates And Salt Concentrations, Maitha Mohammed Al Nuaimi
Theses
Various studies have proved the ability of different types of cyanobacteria and algae to produce hydrogen (H2) by splitting water molecules into H2 and oxygen (O2) using specialized enzymes (hydrogenase and nitrogenase enzymes) through the biophotolysis process. However, the production of O2 acts as the main process inhibitor. Several researchers studied this O2 sensitivity and proposed effective solutions to regulate O2 concentration. By co-culturing algae with aerobic bacteria, the consumption of the resulting oxygen could be attained and thus reducing the sensitivity of the enzyme to the evolved O2. In …
Studying Neurotoxic Effects Of Three Synthetic Insecticides And Two Herbal Infusions On The Nervous System Of The Fruit Fly Drosophila Melanogaster, Sara Khamis Obaid Hamarain Al Dhaheri
Studying Neurotoxic Effects Of Three Synthetic Insecticides And Two Herbal Infusions On The Nervous System Of The Fruit Fly Drosophila Melanogaster, Sara Khamis Obaid Hamarain Al Dhaheri
Theses
Pesticides applied on plants and animals can reach the human diet once they enter food chains. Insecticides are neurotoxic agents; they have the potential of causing damage to the nervous system in people. The damage could induce or promote neurodegenerative diseases such as the Parkinson’s and Alzheimer's. It is well-documented that the exposure to the insecticide chlorpyrifos (CPF) stimulate the Parkinson disease in humans and experimental animals. Thus, this research project will study effect of three synthetic insecticides pirimicarb, tefluthrin, and CPF on the nervous system of Drosophila melanogaster as a model organism. In addition, the project will evaluate the …
The Red Palm Weevil In The Uae: Morphological Diversity And Rnai-Mediated Gene Silencing Of Two Cuticle-Related Genes, Safa Hashem Mohammed Musaed
The Red Palm Weevil In The Uae: Morphological Diversity And Rnai-Mediated Gene Silencing Of Two Cuticle-Related Genes, Safa Hashem Mohammed Musaed
Theses
Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Coleoptera: Curculionidae), threatens palm trees worldwide. A better understanding of this insect can help with designing an adequate management strategy. This study aimed to a better understand the morphological diversity of RPW and examined RNAi-mediated gene silencing of two cuticle-related genes, vestigial (vg) gene, and Laccase (Lac2) gene by injecting the last larval stage with double-stranded RNA (dsRNA). For the morphological diversity study, adults of RPW were collected and classified by their prothoracic spots. Additional morphological characters were measured such as Pronotum Length (PL), Pronotum Width (PW), Elytra Length (EL), Elytra Width (EW), and …
