Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, Mohamed Abdulla Al Muhairi
Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, Mohamed Abdulla Al Muhairi
Theses
Economically important vegetable crop lettuce (Lactuca sativa L.) of family Asteraceae was selected for the present investigation. It is being cultivated in UAE due to its commercial importance. In lettuce cultivation, major problem is the requirement of large quantity of irrigation water. The present study was aimed to reduce the water consumption of lettuce cultivation, for that, a varied irrigation regime was used with the application of abscisic acid (ABA). The parameters studied were growth, photosynthetic pigments, biochemical constituents, antioxidant potential and antioxidant enzymes activities in lettuce plants under drought stress and its response to ABA under stress. Drought stress …
Studies On The Initial Stage Of Lipid Oxidation In Bulk Oils., Elizabeth Budilarto.
Studies On The Initial Stage Of Lipid Oxidation In Bulk Oils., Elizabeth Budilarto.
Theses
During the oxidation of bulk oils, oxidation products (i.e. peroxide values, conjugated dienes and thiobarbituric acid reactive substances) are formed gradually and increased sharply at the end of the induction period. Tocophero1s were consumed, some water was formed, and micelles increased in size during the induction period of vegetable oils oxidized in bulk. The evidence that the evolution of micellar size was in parallel with the end of induction period corroborates the recognition that micelles are the active site of oxidation. The interaction of α-tocophero1 and three synergists: ascorby1 palmitate, phosphatidy1choline and L-lysine were studied in cod liver oil, to …

Study The Quality Of Groundwater Of Al-Zoroup Area In Mahdah State, The Sultanate Of Oman, Fahad Khalifa Rashid Al-Shidi
Study The Quality Of Groundwater Of Al-Zoroup Area In Mahdah State, The Sultanate Of Oman, Fahad Khalifa Rashid Al-Shidi
Theses
The groundwater is the most important source of water in the Sultanate of Oman. Accordingly, the Oman Government has paid great attention commensurate with the importance of water resource in terms of their sources, quality, and ways to rationalize consumption to remain under the term of sustainability and validity of present and future generations. This study was conducted in Al Buraymi at Mahdah State in Al-Zoroub area targete a groundwater quality for 20 wells in private farms. The water samples were taken from these wells and subjected to analysis for microbial and geochemical aspects. For this analysis, the assorted devices …
Growth And Nutrient Uptake Of Young Date Palms In Response To Deficit Irrigation And Partial Rootzone Drying., Noura Mubarak Al Ameri
Growth And Nutrient Uptake Of Young Date Palms In Response To Deficit Irrigation And Partial Rootzone Drying., Noura Mubarak Al Ameri
Theses
In this study young clonal date palm plants were transferred into horizontal split-root pots filled with compost-amended soil of the UAE. The pots were constructed from two adjacent plastic containers, fastened together by adhesive tape. Once the plants had established new roots in the containers, the soil moisture level was measured every two to four days in all soil compartments. In the control treatment, the soil moisture level was brought to 30% w/w after soil moisture recording. Deficit irrigation treatments received exactly 60% of the average amount of water supplied to the pots of the control treatment. In the homogeneous …
Identification Of Novel Natural Compounds With Anti-Breast Cancer Activities, Yusra Saif Al Dhaheri
Identification Of Novel Natural Compounds With Anti-Breast Cancer Activities, Yusra Saif Al Dhaheri
Dissertations
Breast cancer continues to be the leading cause of cancer-related death in women worldwide. In this dissertation, natural compounds with anti-breast cancer activities were identified. We investigated the effect of Salinomycin, a potassium ionophore isolated from Streptomyces albus, on the survival of three human breast cancer cell lines MCF-7, T47D and MDA-MB-231. High concentrations of Salinomycin induced a G2 arrest, down regulation of survivin and triggered apoptosis. Interestingly, treatments with low concentrations of Salinomycin induced a transient G1 arrest at an earlier time and G2 arrest and senescence, associated with enlarged cell morphology, at a later time. There was also …
Assessing The Fishery And Ecology Of Sharks In The United Arab Emirates, Rima W. Jabado
Assessing The Fishery And Ecology Of Sharks In The United Arab Emirates, Rima W. Jabado
Dissertations
Large scale shark population declines have been documented worldwide due to overexploitation and the lack of adequate management frameworks to conserve shark stocks. This study aimed at gaining an understanding of the national shark fishery and the trade in shark products from the United Arab Emirates (UAE). Data were collected from June 2010 to October 2012 through interviews with local fishermen, market and landing site surveys, fishery independent surveys, and stomach content analysis. Interviews with local fishermen (n=126) provided information on the fishery characteristics and established that sharks were increasingly targeted due to their high value in the global fin …
