Application of geopolymers synthesized from incinerated municipal solid waste ashes for the removal of cationic dye from water
( Public Library of Science , 2020 , Article)In this study, municipal solid waste bottom ash (MSW-BA) and fly ash (MSW-FA) were used as a source of aluminosilicate to prepare geopolymer (GEO) adsorbents (GEO-MSWBA and GEO-MSWFA) for the removal of methylene blue (MB) ... -
Carnosol induces ROS-mediated beclin1-independent autophagy and apoptosis in triple negative breast cancer
( Public Library of Science , 2014 , Article)Background: In this study we investigated the in vitro and in vivo anticancer effect of carnosol, a naturally occurring polyphenol, in triple negative breast cancer.Results: We found that carnosol significantly inhibited ... -
Community structure and activity of a highly dynamic and nutrient-limited hypersaline microbial mat in Um Alhool Sabkha, Qatar
( Public Library of Science , 2014 , Article)The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the ... -
Comparative skull analysis suggests species-specific captivity-related malformation in lions (Panthera leo)
( Public Library of Science , 2014 , Article)Lion (Panthera leo) populations have dramatically decreased worldwide with a surviving population estimated at 32,000 across the African savannah. Lions have been kept in captivity for centuries and, although they reproduce ... -
Connecting the dots between PubMed abstracts
( Public Library of Science , 2012 , Article)Background: There are now a multitude of articles published in a diversity of journals providing information about genes, proteins, pathways, and diseases. Each article investigates subsets of a biological process, but to ... -
Date pits based nanomaterials for thermal insulation applications - Towards energy efficient buildings in Qatar
( Public Library of Science , 2021 , Article)Air-conditioning systems make the most significant part of energy consumption in the residential sector. There is no denying that it is essential to produce a comfortable indoor thermal environment for residents in a ... -
Examining the Extinction of the Barbary Lion and Its Implications for Felid Conservation
( Public Library of Science , 2013 , Article)Estimations of species extinction dates are rarely definitive, yet declarations of extinction or extirpation are important as they define when conservation efforts may cease. Erroneous declarations of extinctions not only ... -
Expanding or shrinking? range shifts in wild ungulates under climate change in Pamir-Karakoram mountains, Pakistan
( Public Library of Science , 2021 , Article)Climate change is expected to impact a large number of organisms in many ecosystems, including several threatened mammals. A better understanding of climate impacts on species can make conservation efforts more effective. ... -
Genetic analysis of QTLs controlling allelopathic characteristics in sorghum
( Public Library of Science , 2020 , Article)Mature sorghum herbage is known to contain several water-soluble secondary metabolites (allelochemicals). In this study, we investigated quantitative trait loci (QTLs) associated with allelochemical characteristics in ... -
Global patterns and predictions of seafloor biomass using random forests
