(
Canadian Science Publishing
, 2021 , Article)
Aerial ropeway systems, also called gondolas and aerial cable cars, are amongst driverless transportation modes, which are progressively drawing the attention in promoting tourism. Aerial ropeway systems have been operated ...
Assessing sidewalk and corridorwalkability in developing countries
(
MDPI AG
, 2019 , Article)
Finding a simple and less expensive method to assess and improve sidewalk and corridor conditions in developing countries is essential in order to motivate more people to walk. This study aimed to design and test a method ...
Water-pipe smoking and serum testosterone levels in adult males in Qatar.
(
European Publishing
, 2019 , Article)
Water-pipe (WP) smoking is the most common method of tobacco consumption in the Middle-East and is rapidly spreading on a global scale. Although, water-pipe smoking is linked to various diseases, such as emphysema and ...
Glycine improves peritoneal vasoreactivity to dialysis solutions in the elderly
(
Hamad Medical Corporation
, 2019 , Article)
Background: Peritoneal dialysis solution (PDS) dilates peritoneal microvessels predominantly by the activation of the endothelial nitric oxide (NO) pathway. We made an incidental observation of decreased PDS-induced, ...
Teaching style differences between male and female science teachers in qatari schools: Possible impact on student achievement
(
Modestum LTD
, 2019 , Article)
In Qatar's gender-segregated public schools, female students outperform male students in international science tests such as PISA and TIMMS. In contrast to the international trend for top performing countries, however, ...
Electrically conductive electrospun polymeric mats for sensing dispersed vegetable oil impurities inwastewater
(
MDPI AG
, 2019 , Article)
This paper addresses the preparation of electrically conductive electrospun mats on a base of styrene-isoprene-styrene copolymer (SIS) and multiwall carbon nanotubes (CNTs) and their application as active sensing elements ...
Active and stable methane oxidation nano-catalyst with highly-ionized palladium species prepared by solution combustion synthesis
(
MDPI AG
, 2018 , Article)
We report on the synthesis and testing of active and stable nano-catalysts for methane oxidation. The nano-catalyst was palladium/ceria supported on alumina prepared via a one-step solution-combustion synthesis (SCS) method. ...
