Variance-based global sensitivity analysis of a multi-population, single-chamber microbial fuel cell operating in continuous flow mode at steady state
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)Microbial fuel cells (MFCs) are environmentally friendly devices which are used to convert chemical energy in organic wastes to electrical energy. MFCs have a strong non-linearity that requires a very sophisticated controlling ... -
Variant Enrichment Analysis to Explore Pathways Disruption in a Necropsy Series of Asbestos-Exposed Shipyard Workers
( MDPI , 2022 , Article)The variant enrichment analysis (VEA), a recently developed bioinformatic workflow, has been shown to be a valuable tool for whole-exome sequencing data analysis, allowing finding differences between the number of genetic ... -
Variant Enrichment Analysis to Explore Pathways Functionality in Complex Autoinflammatory Skin Disorders through Whole Exome Sequencing Analysis.
( MDPI , 2022 , Article)The challenge of unravelling the molecular basis of multifactorial disorders nowadays cannot rely just on association studies searching for potential causative variants shared by groups of patients and not present in healthy ... -
Variation in plant litter decomposition rates across extreme dry environments in Qatar
( University of Akron , 2017 , Article Review)Decomposition of plant litter is a key process for transfer of carbon and nutrients in ecosystems. Carbon contained in decaying biomass is released to the atmosphere as respired CO2, a greenhouse gas that contributes to ... -
Variation in temperature and light but not salinity invokes antioxidant enzyme activities in germinating seeds of Salsola drummondii
( Taylor and Francis Ltd. , 2016 , Article)Seeds with efficient antioxidant defence system show higher germination under stress conditions; however, such information is limited for the halophyte seeds. We therefore studied lipid peroxidation and antioxidant responses ... -
Variation of soil properties with sampling depth in two different light-textured soils after repeated applications of urban sewage sludge
( Elsevier , 2021 , Article)Semi-arid agricultural soils have increasingly been subjected to urban sewage sludge (USS) applications due to accelerated soil depletion and shortages in manure supply. Research studies addressing USS reuse have mostly ... -
Variation Of The Electrical Properties Of Manganese Thin Films With Deposition Conditions
( Qatar University , 1989 , Article)The behaviour of the electrical properties of manganese thin films of different thickness (240 - 1500 A) evaporated under different deposition conditions was studied. The effect of the rate of evaporation (1-7 A/s), the ... -
Variation Orders in Building Projects in Khartoum State-Sudan: The Causes and the Impact on Projects Performance
( Qatar Univesrity Press , 2020 , Conference Paper)"Occurrence of variation orders (VOs) is a common phenomenon in building projects and a challenging feature. Opinions and feedback of the stakeholders of building projects at Khartoum State – Sudan were investigated to ... -
Variations in respiratory syncytial virus activity following the relaxation of COVID-19 restrictions in Qatar.
( Oxford University Press , 2022 , Article)Despite the relaxation of COVID-19 restrictions in Qatar in October-December 2020, the detection of RSV was reduced ∼25-fold compared with 2019. This dramatic decrease during the typical RSV season could be related to ... -
Variations in the temperature sensitivity of spring leaf phenology from 1978 to 2014 in Mudanjiang, China
( Springer New York LLC , 2019 , Article)Continuous long-term temperature sensitivity (ST) of leaf unfolding date (LUD) and main impacting factors in spring in the period 1978–2014 for 40 plant species in Mudanjiang, Heilongjiang Province, Northeast China, were ... -
VARIOGRAM MODELING FOR SPATIAL CORRELATION IN STRUCTURAL MRI IMAGES
(06-2 , Master Thesis)In recent years neuroimaging techniques growth help us to understand the working of the human brain by using structural magnetic resonance imaging (sMRI) and functional magnetic resonance imaging (fMRI). Structural MRIs ... -
Various potential techniques to reduce the water footprint of microalgal biomass production for biofuel—A review
( Elsevier B.V. , 2020 , Other)Due to their rapid growth rates, high lipid productivity, and ability to synthesize value-added products, microalgae are considered as the potential biofuel feedstocks. However, among the several bottlenecks that are ... -
