Salt Gland Excretion Efficiency And Salinity Tolerance Of Sporobolus Species, Piumi Shrimani Weragodavidana

Theses

Halophytic C4 grasses, including Sporobolus species, have developed specific mechanisms to cope with salinity stress. Among these, “salt glands” which are bi- cellular leaf epidermal structures eliminating excess saline ions from shoots by excretion under salinity stress. Salt glands are morphologically visible and can potentially be used for salt tolerance breeding programs. The objectives of this study were: (1) to determine the leaf salt gland excretion rates of United Arab Emirates native halophytic chloridoid grass species, S. spicatus and S. arabicus; (2) to determine if leaf salt gland excretion rate and density can effectively predict salinity tolerance among Sporobolus genotypes, …

The Potential Antioxidant And Anti-Inflammatory Effects Of Date Seed Powder In Rats, Fatima Theyab Saif Amer Ai Meqbaali

Theses

Chronic diseases are among the main leading causes of mortality and morbidity in the United Arab Emirates (UAE). Oxidative stress (defined as an imbalance in the reactive oxygen species production/degradation ratio) in interaction with inflammation, has been highlighted as one major underlying mechanism in the development of these diseases. Due to their antioxidant and anti-inflammatory properties, polyphenols could prevent the development of chronic diseases. Interestingly, date seeds are particularly rich in such compounds. Nonetheless, an in vivo study aiming at studying and understanding antioxidant and anti-inflammatory effects of date seeds in serum and various organs is missing. Therefore, the present …

Growth Promotion Of Tomato By The Implementation Of Phosphate Solubilizing Bacteria And Plant Growth Regulators -Producing Bacteria In Calcareous Saline Soil In The United Arab Emirates, Asma Hamad Alsedeeri

Theses

In the present thesis, the ability of different plant growth promoting actinomycetes to promote the growth of tomato plants under saline conditions was examined using phosphorus solubilizing actinomycetes and/or plant growth regulates producing actinomycetes compared to tomato plants grown in soil not amended with any actinomycetes isolates. The overall aim of the present project was to determine whether enhanced phosphorus solubilization, as a result of soil inoculation with either phosphorus-solubilizing actinomycetes and/or with the production of plant growth regulators by plant growth promoting actinomycetes or the combination of both characteristics will results in the promotion of tomato plant growth.

Optimization Of Fuel Consumption For Municipal Solid Waste Collection In Al Ain City, Uae, Elkhalifa Mohamed Zeyada Swar Aldahab

Theses

Collection and transportation of municipal solid waste (MSW) often account for a significant amount of the total budget allocated for waste management. A major portion of that is attributed to fuel consumption. Meanwhile, vehicles involved with waste collection can emit significant levels of atmospheric pollutants. Hence, optimization of waste collection yields both financial and environmental benefits. No work has been done to optimize fuel consumption during MSW collection in Al Ain city. In this study, several cases were developed using ArcGIS Network Analyst tool in order to establish optimum conditions for MSW collection in Um Gafa district in Al Ain …

Study Of The Seasonal And Interannual Variability Of Phytoplankton Bloom In Arabian Gulf Using Modisdata, Malik Mutasim Malik Gasim

Theses

The Arabian Gulf is a semi enclosed large water body that experiences seasonal

variations and reversal of it water currents flow circulation. The Gulf waters are characterized by having high primary productivity and strong phytoplankton blooms at particular seasons within the year. Phytoplankton is a base of the food chain for marine species, providing an essential food resource for aquatic life. Marine phytoplankton affects the diversity of any marine ecosystem and drives its functioning and is strongly correlated with fishery yields. The primary

objectives of this research study are to answer key research questions related to phytoplankton blooms in the …
