Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
(
Trans Tech Publications
, 2010 , Conference Paper)
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 ...
Lithology, mineral assemblages and microbial fingerprints of the evaporite-carbonate sediments of the coastal sabkha of Abu Dhabi and their extraterrestrial implications
(
cambridge university press
, 2010 , Article)
Deep-core and surface samples collected from the coastal sabkha of Abu Dhabi were subjected to a multi-proxy study, including petrographic, geochemical and spectroscopic analyses. The sediments studied are composed of ...
Mangrove-bearing limestone from the Eocene Dammam Formation, Arabian Gulf: Implications for the mangrove dispersal controversy
(
springer link
, 2012 , Article)
Fossil mangrove remains are found within the shallow carbonate strata of the Middle Eocene Dammam Formation of the Arabian Gulf. This formation is of wide distribution across most eastern parts of the Arabian Platform and ...
Microbial dolomites from carbonate-evaporite sediments of the coastal sabkha of Abu Dhabi and their exploration implications
(
wiley online library
, 2010 , Article)
Detailed petrographic studies of Recent dolomites from the coastal sabkha of Abu Dhabi using SEM and Energy Dispersive X-ray (EDX) analyses indicate that most of the dolomite started to form in " micro-niches" (i.e. small ...
Physico-chemical characteristics of oil produced from seeds of some date palm cultivars (Phoenix dactylifera L.) .
(2015 , Article)
The oil content of saturated and unsaturated fatty acids with some physico-chemical properties and nutrients were investigated in oil produced from seeds of six important date palm cultivars and one seed strain present in ...
Baseline concentrations and distributions of Polycyclic Aromatic Hydrocarbons in surface sediments from the Qatar marine environment
(
Elsevier
, 2017 , Article)
Coastal sediments in marine waters of Qatar have the potential of being contaminated by Polycyclic Aromatic
Hydrocarbons (PAHs) due to extensive petroleum exploration and transportation activities within Qatar's ...
Microstructural investigation of gamma-irradiated ultra high molecular weight polyethylene in nitrogen atmosphere
(
Trans Tech Publications
, 2010 , Conference Paper)
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 ...
Seismic detection of a sinkhole using spectral-based analysis
(
Society of Exploration Geophysicists
, 2014 , Conference Paper)
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 ...
Stratigraphy and petroleum systems of the Paleozoic (pre-Khuff) succession, Qatar
(
Wiley
, 2016 , Article)
A thickness of more than 1500m of Palaeozoic (pre-Khuff) siliciclastic strata were
encountered in three deep wells (Matbakh A, and Dukhan A and B) drilled in the State of
Qatar. These sedimentary rocks have no formal ...
Investigating chlorophyll and nitrogen levels of mangroves at Al-Khor, Qatar: an integrated chemical analysis and remote sensing approach. Environmental Monitoring and Assessment
(
Springer Verlag
, 2016 , Article)
Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were ...
