Dispersion Behaviors of Flare Gases in Different Weather Conditions
( Qatar University Young Scientists Center - Qatar University , 2024 , Conference Paper)Flare gases, consisting of methane and other volatile organic compounds, are byproducts of oil and gas extraction. While flaring serves as a safety measure, it contributes to greenhouse gas emissions and releases pollutants ... -
Dispersion of soft Bi particles and grain refinement of matrix in an Al-Bi alloy by equal channel angular pressing
( Elsevier BV , 2014 , Article)The deformation behavior of a soft particle containing Al-8Bi hypermonotectic alloy during equal-channel angular pressing was studied. The size, shape and distribution of soft Bi particles are substantially modified via ... -
Dispersion of waves characteristics of laminated composite nanoplate
( Techno-Press , 2021 , Article)The current work fills a gap of a small-scale study on wave propagation behavior of symmetric, antisymmetric, and quasi-isotropic cross/angle-plies laminated composite nanoplates. The governing equations are derived through ... -
Displaced Population: A Case Study of the Syrian Forced Migrants in Qatar
(2019 , Master Thesis)Since the outbreak of the Syrian conflict in 2011, roughly 5.6 million Syrians have fled the country as a result of the ongoing conflict in the region. Many of them have crossed into Gulf nations such as Qatar, even though ... -

Dissecting the claims of legitimization for the ritual of female circumcision or female genital mutilation (FGM)
( Bloomsbury Qatar Foundation Journals , 2014 , Article)This work analyses the various arguments put forward by the supporters of female genital mutilation (FGM) under Islamic law to determine whether this practice has its roots in Islam, whether it is a customary or cultural ... -
Dissipativity Analysis of a Class of Competitive Neural Networks with Proportional Delays
( Springer Verlag , 2019 , Conference Paper)This paper dealt with the dissipativity problem for a class of competitive neural networks with proportional delays. Based on Lyapunov functionals approach, new sufficient conditions are derived to ensuring the strictly ... -
Dissolution kinetics of different inorganic oilfield scales in green formulations
( American Chemical Society , 2020 , Article)Scale mineral deposition is a critical problem that hinders the daily production of oil and gas fields. Chemical removal of these scales, based on the scale type, is common. In this paper, borax and diethylene tremaine ... -
Distance learning as emergency remote teaching vs. traditional learning for accounting students during the COVID-19 pandemic: Cross-country evidence
( Elsevier , 2022 , Article)The main objective of the current study is to examine the perspectives of undergraduate accounting students on the transition to distance learning (DL) as emergency remote learning from traditional learning (TL) during the ... -
Distance power system protection in presence of renewable energies (solar and wind)
(2021 , Master Thesis)Renewable energy become widely used in recent years in order to reduce CO2 emission, which produce from burning oil and gas to generate electrical energy. Solar and wind energies are the main types of renewable energies, ... -
Distance Protection of Power System in presence of FACTS elements
(2020 , Master Thesis)With the development and implementation of various compensation devices, i.e. Flexible AC Transmission Systems (FACTS), protection relays are inevitably impacted in negative ways causing loss of protection accuracy. ... -
Distance Teaching and Sustainability: Where does it begin?
( Qatar University , 2020 , Video) -
Distance-differential protection of transmission lines connected to wind farms
( Elsevier Ltd , 2017 , Article)Distance relays are often used in the protection of the transmission lines connected to the wind farms. The distance relay using the transmission line impedance measurement identifies the type and location of the fault. ... -
Distinct antibody repertoires against endemic human coronaviruses in children and adults.
( American Society for Clinical Investigation , 2021 , Article)Four endemic human coronaviruses (HCoVs) are commonly associated with acute respiratory infection in humans. B cell responses to these "common cold" viruses remain incompletely understood. Here we report a comprehensive ... -
Distinct Clinical and Prognostic Features of Myelodysplastic Syndrome in Patients from the Middle East, North Africa, and Beyond: A Systemic Review
( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)Myelodysplastic syndrome (MDS) describes a group of bone marrow malignancies with variable morphologies and heterogeneous clinical features. The aim of this study was to systematically appraise the published clinical, ... -
Distinct genomic features across cytolytic subgroups in skin melanoma.
( Springer , 2021 , Article)Skin melanoma is a highly immunogenic cancer. The intratumoral immune cytolytic activity (CYT) reflects the ability of cytotoxic T and NK cells to eliminate cancer cells, and is associated with improved patient survival. ... -
