Price Elasticity And Determinants Of Residential Water Consumption In Al Ain Region, Bara Mohamad Alrefai Nov 2020

Price Elasticity And Determinants Of Residential Water Consumption In Al Ain Region, Bara Mohamad Alrefai

Civil and Environmental Theses

This thesis is concerned with the effect of water price on residential water consumption in the Al Ain region. Water demand worldwide significantly increased due to high population growth, climate change, and lifestyle changes. Fulfilling the growing water demand by constantly increasing supply has several environmental and economic implications. Water management strategies assist in driving the water industry to develop better solutions to address the increase in water demand. The UAE recently shifted its water management strategies towards demand management to reduce the growing demand in the country. Water pricing is considered one of the important tools to reduce residential …


2d Audio Magnetotelluric (Amt) Data Inversion Of Al-Jaww Plain Area (Al-Ain, Uae) For Groundwater Aquifer Investigations, Ahmad Esam Alaran Nov 2020

2d Audio Magnetotelluric (Amt) Data Inversion Of Al-Jaww Plain Area (Al-Ain, Uae) For Groundwater Aquifer Investigations, Ahmad Esam Alaran

Theses

The United Arab Emirates (UAE) is considered within the arid climate zone having low rates of annual rainfall. The freshwater is mainly located in shallow groundwater aquifers. Understanding the depth and extent of such aquifers is an important issue for UAE local governments and environmental agencies. Hydrogeological conditions in the UAE are strongly related to the topographic features and are dominated by a mountain range in Oman at the eastern margin of the Arabian Platform. The alluvial plains such as Al-Jaww plain (eastern Al-Ain city) is considered as an important potential source of groundwater for the Al-Ain region. Al-Jaww plain …


Heavy Oil Production, Review Paper, Mohamed Abd El-Moniem Sep 2020

Heavy Oil Production, Review Paper, Mohamed Abd El-Moniem

Emirates Journal for Engineering Research

Petroleum represents an important source of energy. The different resources for energy are classified into renewable and non-renewable. Petroleum is the main source of the non-renewable energy where it is found in conventional and non-conventional reservoirs. Conventional oil production is started since the last century with a high oil and gas production using primary and secondary recovery. Now, the global demand is high compared to the supply from the existing produced fields. The production is declining from the conventional resources, so the production from the unconventional reservoirs is essential to cover the market demand. The unconventional resources are classified as …


Biological Control Of Fusarium Wilt In Date Palm (Phoenix Dactylifera L.) In The United Arab Emirates By Endophytic Actinobacteria, Aisha Abdullah Darwish Shambeh Alblooshi Jun 2020

Biological Control Of Fusarium Wilt In Date Palm (Phoenix Dactylifera L.) In The United Arab Emirates By Endophytic Actinobacteria, Aisha Abdullah Darwish Shambeh Alblooshi

Theses

Date palm trees suffer from many various serious diseases, including sudden decline syndrome (SDS). External symptoms were characterized by whitening on one side of the rachis, progressing from the base to the apex of the leaf until the whole leaf dies; while the internal disease symptoms included reddish roots and highly coloured vascular bundles causing wilting and death of the tree. Although three Fusarium spp. (F. oxysporum, F. proliferatum and F. solani) were isolated from diseased root samples, the fungal pathogen F. solani was associated with SDS on date palm in the United Arab Emirates (UAE). Fusarium spp. were identified …


Biological Control Of Sudden Decline Disease Of Date Palm (Phoenix Dactylifera L.) In The United Arab Emirates, Khawla Juma Saif Zeail Alwahshi Jun 2020

Biological Control Of Sudden Decline Disease Of Date Palm (Phoenix Dactylifera L.) In The United Arab Emirates, Khawla Juma Saif Zeail Alwahshi

Theses

Date palm orchards suffer from serious diseases, including sudden decline syndrome (SDS). The fungal pathogen Fusarium solani was associated with SDS on date palm in the United Arab Emirates (UAE). Application of Cidely® Top (difenoconazole and cyflufenamid) significantly inhibited the fungal mycelial growth In vitro and reduced SDS development on date palm seedlings pre-inoculated with F. solani under greenhouse conditions. This is the first report confirming that the chemical fungicide Cidely® Top is strongly effective against SDS on date palm. Fungal pathogens not only inhibit plant growth directly but also induce the plant to synthesize stress ethylene. Much of the …


Characterization Of Metals And Non-Metals In The Indian Oil Sardine (Sardinella Longiceps) In The Northern United Arab Emirates, Shaima Malik Jun 2020

Characterization Of Metals And Non-Metals In The Indian Oil Sardine (Sardinella Longiceps) In The Northern United Arab Emirates, Shaima Malik

Biology Theses

The marine ecosystems of the world are especially susceptible to pollution arising from anthropogenic sources. The Arabian Gulf ecosystem is a partially enclosed hypersaline system with increasing levels of pollution arising from ongoing development in the region. Marine biota are expected to be influenced by pollutants and levels of trace elements in marine species could be indicative of increasing pollution. Bioaccumulation of 19 elements (As, Ca, Cd, Co, Cr, Cu, Hg, K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sr, V, Zn) in 120 specimens of Indian oil sardines (Sardinella longiceps) purchased from local fish markets of …


The Ecological Impacts Of Changing Rainfall On The Arabian Peninsula, Zahra Ahmed M Alsomali Jun 2020

The Ecological Impacts Of Changing Rainfall On The Arabian Peninsula, Zahra Ahmed M Alsomali

Civil and Environmental Theses

The Arabian Peninsula is one of the hottest and driest regions in the world, and with climate change, not only is it getting hotter, it is also getting drier. It may be that the desert species here are well-adapted to dry conditions, in which case they may be able to withstand the changes, but it may be that desert species are already challenged by the extremely dry conditions. Here, data from 167 published studies were used to look at whether desert species were living below their optimum rainfall, and to compare the findings with species in other biomes. In all …


Remediation Of Crude Petroleum Oil-Water Emulsions Using Microalgae, Mohamed Shafi May 2020

Remediation Of Crude Petroleum Oil-Water Emulsions Using Microalgae, Mohamed Shafi

Civil and Environmental Theses

Crude petroleum oil spills are among the most important organic contaminations, which result from uncontrolled releases and spillages during transportation or storage. The separated oils on that accumulate on top of the water can be removed by various conventional skimming methods. However, the emulsified portions that remain within the water phase are more difficult to remove and pose significant threats to the environment and could tamper the tertiary treatment in a wastewater treatment plant. Biological treatment, using bacteria, have proven to be an effective method in the removal of the emulsified oils. However, the biomass produced in this case does …


Assessment Of The Impact Of Climate Change On Land Use In The Emirate Of Abu Dhabi - An Environmental And Socio-Economic Perspective, Latifa Saeed Al Blooshi Apr 2020

Assessment Of The Impact Of Climate Change On Land Use In The Emirate Of Abu Dhabi - An Environmental And Socio-Economic Perspective, Latifa Saeed Al Blooshi

Dissertations

This dissertation focuses on the impact of climate change on land use in the Emirate of Abu Dhabi – UAE. Climate change is a significant challenge resulting from natural and anthropogenic causes. Land use can stimulate changes in communities under climate change. The main objective of this dissertation is to assess the impact of climate change from an environmental and socio-economic perspective. In 2001, coastal sabkhas, mixed class and urbanized areas experienced an increase in temperature by (0.67, 1.14 and 1.16°C) respectively. In cities, urban areas are warmer than neighbouring rural areas. Unexpectedly, urbanization in desert areas in UAE led …
