Assessing uncertainty in sighting records: An example of the Barbary lion
(
PeerJ
, 2015 , Article)
As species become rare and approach extinction, purported sightings can be controversial, especially when scarce management resources are at stake.We consider the probability that each individual sighting of a series is ...
Adsorption of 2, 4-dichlorophenoxyacetic acid onto date seeds activated carbon: Equilibrium, kinetic and thermodynamic studies
(2012 , Article)
Adsorption isotherm and kinetics of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide on activated carbon prepared from Barhi date seeds were determined from batch tests. The effects of contact time, initial herbicide ...
Tailoring the reducibility and catalytic activity of CuO nanoparticles for low temperature CO oxidation
(
Royal Society of Chemistry
, 2018 , Article)
Copper oxide (CuO) nanoparticles have received considerable interest as active and inexpensive catalysts for various gas–solid reactions. The CuO reducibility and surface reactivity are of crucial importance for the high ...

(
Taylor & Francis
, 2015 , Article)
We report the findings of a qualitative study of Qatari homes in the Arab Gulf. We identify the significance of privacy and gender segregation as anchors for identity, both national and religious. Maintaining these anchors ...
Soft biodegradable elastomers based on poly (octanediol-tartarate) for drug delivery and tissue engineering: Synthesis, characterization and biocompatibility studies
(
Taylor & Francis
, 2011 , Article)
The synthesis, characterization and cytocompatibility of amorphous poly (octanediol-tartarate) thermoset biodegradable elastomeric polyesters are reported. The synthesis was achieved by preparing an aliphatic saturated ...
Effect of soil moisture on the response of soil respiration to open-field experimental warming and precipitation manipulation
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2017 , Article)
Soil respiration (RS, Soil CO2 efflux) is the second largest carbon (C) flux in global terrestrial ecosystems, and thus, plays an important role in global and regional C cycling; moreover, it acts as a feedback mechanism ...
Dynamics of charge evolution in glass capillaries for 230-keV Xe23 + ions
(
American Physical Society
, 2012 , Article)
We have measured the transmission of 230-keV (10-keV/q) Xe23+ ions through insulating tapered glass capillaries of microscopic dimensions. The dynamics of charging and discharging processes have been investigated, evidencing ...
