A systematic review on the bioremediation of metal contaminated soils using biochar and slag: current status and future outlook
( Springer , 2023 , Article Review)Heavy metals contaminated soils are posing severe threats to food safety worldwide. Heavy metals absorbed by plant roots from contaminated soils lead to severe plant development issues and a reduction in crop yield and ... -
Functionality of the temperate forests in the Western Himalaya with changing climate
( Springer , 2023 , Article)Climate change may potentially affect the biodiversity and functionality of forests globally. An understanding of the relationship between biodiversity and forest ecosystem functioning can be attained by evaluating variations ... -
A quantity-distribution synthesized framework for risk assessment of algal blooms
( Elsevier , 2023 , Article)Algal blooms threaten water safety and quality, particularly in lakes with vulnerable environment and advanced urbanization. Due to low water exchange rate and multiple human activity influences, algal blooms in inland ... -
Climatic drivers and ecological implications of variation in the time interval between leaf-out and flowering
( Elsevier , 2023 , Article)Leaf-out and flowering in any given species have evolved to occur in a predetermined sequence, with the inter-stage time interval optimized to maximize plant fitness. Although warming-induced advances of both leaf-out and ... -
Raman spectroscopy of the Dukhan sabkha: identification of geological and biogeological molecules in an extreme environment
( The Royal Society , 2010 , Article)The characterization of minerals and biogeological deposits in a terrestrial Arabian sabkha has a direct relevance for the exploration of Mars since the discovery by the NASA rovers Spirit and Opportunity of evaporate ... -
Seismic detection and characterization of a man-made karst analog - A feasibility study
( Society of Exploration Geophysicists , 2021 , Article)At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ... -
Comprehensive pore size characterization of Midra shale
( Elsevier B.V. , 2021 , Article)Although the Middle East's carbonate reservoirs were the first and most studied rocks in the world, Middle Eastern shale reservoirs are still poorly understood compared with other unconventional formations in the US. We ... -
Characterizing fracture toughness using machine learning
( Elsevier B.V. , 2021 , Article)The existing models for fracture toughness characterization based on nanoindentations that account for the fracture length are limited to simple (ideal) geometries that are absent in shales. The present study proposes two ... -
Dolomite: Perspectives on a perplexing mineral
( research qate , 2009 , Article Review)Dolomite is a metastable mineral that can precipitate directly from solutions containing magnesium, calcium and carbonate to form cement or unlithified sediment. It can be categorized into two classes such as penecontemporaneous ... -
Long-term assessment of onshore and offshore wind energy potentials of Qatar
( MDPI AG , 2021 , Article)Exploitation of conventional energy resources has caused a deliberate increase in the emitted carbon in the atmosphere, which catalyzes global warming trends. This is a matter of concern, especially in Qatar, where fossil ... -
Sentinel-2 image transformation methods for mapping oil spill – A case study with Wakashio oil spill in the Indian Ocean, off Mauritius
( Elsevier B.V. , 2021 , Article)Although several indices have been constructed and available at the Index database (IDB) for Sentinel-2 satellite to map and study several earth resources, no indices have been developed to map oil spill. We constructed ... -
Seismic detection of a sinkhole using spectral-based analysis
( Society of Exploration Geophysicists , 2014 , Conference)Seismic data recorded during a survey in the vicinity of a sinkhole revealed distinct resonances at 70 Hz. Frequency domain data inversion based on exact modeling produced effective elastic parameters for the location over ... -
