Geometrical and Electronic Analysis of Polyepoxysuccinic Acid (PESA) for Iron Sulfide Scale Inhibition in Oil Wells
( MDPI , 2022 , Article)Scale formation causes major losses in oil wells, related to production and equipment damages. Thus, it is important to develop effective materials to prevent scale formation and inhibit any additional formation. One known ... -
Geometrical approach for wind farm symmetrical layout design optimization
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Wind farm layout orientation plays an important factor to reduce the total wake loss and hence increase the capacity factor of the wind farm. Different wind farms layout design optimization techniques are widely used and ... -
Geometrical investigation of piezoelectric patches for broadband energy harvesting in non-deterministic composite plates
( MDPI , 2021 , Article)Mechanical energy is the most ubiquitous form of energy that can be harvested and converted into useful electrical power. For this reason, the piezoelectric energy harvesters (PEHs), with their inherent electromechanical ... -
Geometrically nonlinear vibration analysis of eccentrically stiffened porous functionally graded annular spherical shell segments
( Taylor and Francis Ltd. , 2022 , Article)This article investigates nonlinear free vibrations of porous functionally graded (FG) annular spherical shell segments surrounded by elastic medium and reinforced by circumferential stiffeners. Porous FG material contains ... -
Geomorphology of the Nagada Region Upper Egypt
( Qatar University , 1982 , Article)Detailed geomorphological study of the Nagada region, west of-the Nile enables us to better understand the main landfonns in this part of Upper Egypt. Six geomorphic features are recognized including: the Thebaid plateau; ... -
Geopolitics of the New Middle East: Perspectives from Inside and Outside
( Routledge , 2021 , Article)In the last decade, the broader Middle East and North Africa (MENA) regional security environment has been shaped by the cycle of insecurity and instability. The structural transformation in the MENA has unleashed such ... -
Geospatial assessment of the carbon footprint of water and electricity consumption in residential buildings in Doha, Qatar
( Elsevier , 2024 , Article)The process of estimating the carbon footprint (CF) has become a key method for managing greenhouse gas (GHG) emissions, guiding strategies for emission reduction and validating those strategies. Given the complexity of ... -
Geosynthetic-reinforced soils above voids: Observation and prediction of soil arching
( Elsevier , 2021 , Article)The assumption with the biggest impact on the design of geosynthetic-reinforced soils above voids is the presence and degree of soil arching, which affects the predicted applied stress on the geosynthetic. A series of ... -
Geosynthetic-reinforced soils above voids: Observation of soil and geosynthetic deformation mechanisms
( Elsevier , 2021 , Article)Understanding how a geosynthetic-reinforced soil deforms in response to the formation of an underlying void is crucial to provide appropriate designs of these systems. Centrifuge models employing a trapdoor to simulate the ... -
Geotechnical Aspects of Sub-Sea Tunnelling on the Musaimeer Pumping Station and Outfall Tunnel Project
( Qatar Univesrity Press , 2020 , Conference Paper)Musaimeer outfall tunnel is one of the longest storm water tunnels in the world with a total length of 10.2 km. The tunnel is connected via a drop shaft to the main pump station. This system will accommodate surface and ... -
Geotechnical Challenges for Underground Infrastructure in Qatar: Hydrogeological Assessment for Dewatering and Deep Excavation Works: South of Wakrah Pumping Station and Outfall (SWPSO) Project
( Qatar University Press , 2023 , Conference Paper)The evaluation of hydrogeological conditions and groundwater inflows, as part of the geotechnical risk assessment, poses one of the key challenges during the design and construction of major infrastructure projects and ... -
Geotechnical considerations on the design of piled rafts on rock
( Research Publishing Services , 2011 , Conference Paper)This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ... -
Geothermal energy extraction from decommissioned petroleum wells
( International Society for Rock Mechanics , 2014 , Conference Paper)Abandoned wells impose enduring liabilities to petroleum companies and/or governments. However, the depth and abundance of abandoned petroleum wells make them an economically attractive source of geothermal energy. Geothermal ... -
Geriatric education in schools of pharmacy: Students' and educators' perspectives in Qatar and Canada
