Oil-polluted groundwater in central and west Iraq as indicator of potential new hydrocarbon plays
( Taylor and Francis Ltd. , 2023 , Article)The old land of Iraq is characterized by the presence of many oil seepages that date back to the Babylonian time. During the last few years, the country has witnessed an accelerating pattern of earthquakes that may have ... -
Empirical Relation for Capillary Pressure in Shale
( Society of Petroleum Engineers (SPE) , 2022 , Article)Brooks and Corey (1964) and van Genuchten (1980) proposed the two most widely used relations for approximating capillary pressure. Petroleum engineers apply both, but they were originally proposed to understand the moisture ... -
Microporosity evolution and destruction in the Jurassic Arab D reservoir, Qatar
( Institute for Ionics , 2023 , Article)Core samples were collected from three wells, one onshore and two offshore, from Qatar’s Upper Jurassic Arab D reservoir. The samples were subjected to multiproxy petrographic and chemical analyses to identify their micro- ... -
Remote sensing of desertification and study of temporal variability of aeolian deposits in parts of the Arabian Desert for sustainable development in an arid environment
( Academic Press Inc. , 2023 , Article)Aeolian deposit in part of the Arabian Desert is mapped using ASTER data to understand desertification, land encroachment, and degradation, and to assess agricultural development in arid regions. In this study, the ... -
Variability of blue carbon storage in arid evaporitic environment of two coastal Sabkhas or mudflats
( Nature Research , 2023 , Article)Coastal Sabkhas are mudflats found in arid coastal regions that are located within the supratidal zone when high rates of evaporation lead to high salinity. While evaporitic minerals often accumulate underneath the surface, ... -
Microbially influenced formation of anhydrite at low temperature
( Elsevier B.V. , 2023 , Article)Calcium sulfate minerals are abundant in nature – on Earth and on Mars – and important in several fields of material sciences. With respect to gypsum and bassanite, anhydrite represents the anhydrous crystalline phase in ... -
How Efficient Would Demand-Based Water Strategies Be for Qatar?
( Qatar University Press , 2023 , Conference)Qatar is a water scarce country that heavily relies on seawater desalination. Multiple studies have concluded the need for a more resilient water planning through efficient "demand control" strategies. This study is among ... -
Evaluation of processed sludge as a sustainable and efficient soil conditioner and organic fertiliser for Qatari soil
( Inderscience Publishers , 2022 , Article)Qatar is implementing the use of treated sludge as a sustainable resource in the green infrastructure. The study employed an experimental research design where five samples (two kilograms each) of pelletised sludge of both ... -
Polymer-metal oxide composite nanofibers
( Elsevier , 2021 , Book chapter)Extensive studies have been conducted on different kinds of polymers, their composites, and multifunctionalities, depending on their structural features. Metal oxides and their polymer nanocomposites offer technological ... -
Probabilistic human health risk assessment of trace elements in ballast water treated by reverse osmosis desalination plants
( Elsevier , 2023 , Article)Very few studies have paid attention to the transport of heavy and toxic metals via ballast water coming from different countries of the world. In the present study, ballast water samples (n = 83) were collected from ships, ... -
Substantiation of propitious “Enzybiotic” from two novel bacteriophages isolated from a wastewater treatment plant in Qatar
( Springer Nature , 2022 , Article)Lysin of bacteriophages isolated from a particular ecosystem could be inducted as a bio-controlling tool against the inhabiting pathogenic bacterial strains. Our study aims at both experimental and computational characterization ... -
Genomic Characterization and Annotation of Two Novel Bacteriophages Isolated from a Wastewater Treatment Plant in Qatar
( American Society for Microbiology , 2022 , Article)We report the genome sequences of Escherichia phage C600M2 (length, 88,162 bp; G1C content, 38.98%) and Escherichia phage CL1 (length, 87,820 bp; G1C content, 41.32%), which were isolated from a wastewater treatment plant ... -
Human health risks associated with trace metals in dust of residential arid areas
( Elsevier , 2023 , Article)Composite dust samples were collected on a monthly basis over a full year from Doha, Qatar. Inductively Coupled Plasma Mass Spectrometry (ICPMS) was used for the determination of total concentrations of Na, K, Mg, Ca, Li, ... -
Mapping of trace elements in topsoil of arid areas and assessment of ecological and human health risks in Qatar
( Elsevier , 2023 , Article)Soil is the incubator of human activities. Mapping of soil contaminants needs to be constantly updated. It is fragile in arid regions, especially if it accompanies dramatic and successive industrial and urban activities ... -
