Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar
(
Elsevier
, 2015 , Article)
A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the
first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m 3) in water filters was found to be in
the ...
Effect of chain structure on the properties of Glass fibre/polyethylene composites
(
Elsevier, Ltd
, 2013 , Article)
Three types of polyethylenes (low density: LDPE, medium density: MDPE, and high density: HDPE) were used to investigate the effect of chain branching on the dispersion and adhesion in Glass fibre reinforced polymer composites. ...
Specific gene patterns and molecular pathways related to human carcinogenesis in different populations among various geographic locations.

Interface modification of compatibilized polyethylene terephthalate/polypropylene blends: Effect of compatibilization on thermomechanical properties and thermal stability
(
WILEY-VCH Verlag
, 2015 , Article)
Polyethylene terephthalate (PET) and polypropylene (PP) are incompatible thermoplastics because of differences in chemical structure and polarity, hence their blends possess inferior mechanical and thermal properties. ...
