Chemical Characterization and Source Identification of Beached Oil from Two Areas Along the North-Western Coast of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference)Over the years there have been several reports of oil spills affecting particularly the northern coast of Qatar. In most cases, the source of oil spills is not identified. The spilled oils are very resistant to degradation ... -
Diagenetic Alterations of the Outcropped Lower Triassic Mahil Formation (KS-1 Khuff-Equivalent) in the Oman Mountains, North Oman
( Springer Nature , 2023 , Conference)The Lower Triassic Mahil Formation in North Oman is the outcrop time-equivalents to the hydrocarbon-bearing reservoir, Upper Khuff Formation (referred to as KS-1 cycle). The studied sections of the KS-1 cycle in the ... -
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
( Trans Tech Publications , 2010 , Conference)Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ... -
Microstructural investigation of gamma-irradiated ultra high molecular weight polyethylene in nitrogen atmosphere
( Trans Tech Publications , 2010 , Conference)In this paper the results of structural changes in ultra high molecular polyethylene (UHMWPE) upon gamma irradiation and storage in nitrogen environment are reported. Based on differential scanning calorimetry (DSC), wide ... -
Modelling of Oil-Sediment Aggregates Trajectories Along Gulf of Khambhat, West Coast of India
( Springer Science and Business Media Deutschland GmbH , 2021 , Conference)Oil spill accidents on the marine waters impose great threat to the marine organism, humans and economic. Continuous efforts have been made to achieve effective mitigation measures to avoid the damage to the marine ... -
Qatar’s vision of global problems, challenges and solutions
( QScience - Hamad Bin Khalifa University Press , 2016 , Conference)Since Qatar first signed the Biodiversity Convention in Rio in 1992, Qatar has been a strong advocate with keen interest in sustainability and the preservation of its biodiversity noting that advancement in industry should ... -
Screening Of Some Qatari Plant Extracts For Anti Fungal Activities Of Plant Pathogenic Fungi
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference)The present study aimed to evaluate the antifungal activity of three desert plants extracts grown naturally in Qatar: (Al-rayhan) Ocimum basilicum, Shafallah (Capparis spinosa) and Qwaif(Prosopis juliflora)to study their ... -
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 ...
