This study presents the taxonomic description of two new sponge species that are intimately associated with the hyperarid mangrove ecosystem of Qatar. The study includes a preliminary evaluation of the sponges' potential ...
Effect of U-turns and heavy vehicles on the saturation flow rates of left-turn lanes at signalized intersections
(
MDPI
, 2020 , Article)
© 2020 by the authors. The Saturation Flow Rate (SFR) is a primary measure that can be used when estimating intersection capacity. Further, the efficiency of signal control parameters also depends on the accuracy of assumed ...
Production of flexible nanocomposite membranes for x-ray detectors
(
Elsevier
, 2020 , Article)
Flexible membranes of poly(vinyl alcohol) (PVA) polymer and CuO nanoparticles for x-ray detection applications are reported in this work. PVA represents a polymer matrix for nanoparticles, and its flexibility and electrical ...
First principle investigation of H2Se, H2Te and PH3 sensing based on graphene oxide
(
Elsevier
, 2020 , Article)
Detecting toxic gases is of great importance to protect our health and preserve the quality of life. In this work, graphene (G) and graphene oxide with three different modifications (G–O, G–OH, and G–O–OH) have been used ...
DFT investigation of H2S adsorption on graphenenanosheets and nanoribbons: Comparative study
(
Elsevier
, 2020 , Article)
Graphenenanosheet (GNS), armchair graphenenanoribbon (AGNR), and zigzag graphenenanoribbon (ZGNR) systems were investigated by first principle calculations using the density functional theory (DFT). The DFT calculations ...

Bryophyte cover and richness decline after 18 years of experimental warming in alpine Sweden.
(
Oxford University Press
, 2020 , Article)
Climate change is expected to affect alpine and Arctic tundra communities. Most previous long-term studies have focused on impacts on vascular plants, this study examined impacts of long-term warming on bryophyte communities. ...
Antibiotic resistance and virulence patterns of pathogenic Escherichia coli strains associated with acute gastroenteritis among children in Qatar
(
BMC
, 2020 , Article)
Background: The treatment of Enterobacteriaceae family including diarrheagenic E. coli (DEC) has been increasingly
complicated due to the emergence of resistant strains. Here we report on the phenotypic resistance profiles ...
