A comparison of the Ranging behaviour and habitat use of the Ethiopian hedgehog (Paraechinus aethiopicus) in Qatar with hedgehog taxa from temperate environments
( NaturePublishingGroup , 2018 , Article)We investigated seasonal changes in the ecology and behaviour of the Ethiopian hedgehog (Paraechinus aethiopicus) in Qatar, particularly in respect to differences in behaviour between hedgehogs living in arid environments ... -
A comprehensive review summarizing the recent biomedical applications of functionalized carbon nanofibers
( John Wiley and Sons Inc , 2021 , Article)Since the discovery and fabrication of carbon nanofibers (CNFs) over a decade ago, scientists foster to discover novel myriad potential applications for this material in both biomedicine and industry. The unique economic ... -
A computational study on molecular structure and stability of tautomers of dipyrrole-based phenanthroline analogue
( Elsevier B.V. , 2018 , Article)This work reports structure and stability of different tautomers of a newly-designed analogue of 1,10-phenanthroline-5,6-dione (the di-keto structure (DK) derived from 1H,8H-pyrrolo[3,2-g]indole (PI)) using quantum chemical ... -
A Concubine in Early-Modern Egypt: The Example of Nafisa Khatun al-Muradiyya
( Brill Academic Publishers , 2016 , Article)This article portrays the life of Al-Sit Nafisa Khatun al-Muradiyya, originally taken captive in Georgia and sold into slavery in Cairo, who rises from life as a concubine to become the wife of the Mamluk leader Murad Bey ... -
A Cross-Coupling Approach to Amide Bond Formation from Esters
( American Chemical Society , 2017 , Article)A palladium-catalyzed cross-coupling between aryl esters and anilines is reported, enabling access to diverse amides. The reaction takes place via activation of the C-O bond by oxidative addition with a Pd-NHC complex, ... -
A discussion on generalized almost contractions via rational expressions in partially ordered metric spaces
( Springer International Publishing , 2014 , Article)The main purpose of this paper is to give some fixed point results for mappings involving generalized (Formula presented.)-contractions in partially ordered metric spaces. Our results generalize, extend, and unify several ... -
A disease-modifying treatment for Alzheimer's disease: Focus on the trans-sulfuration pathway
( De Gruyter , 2019 , Article)High homocysteine levels in Alzheimer's disease (AD) result from low activity of the trans-sulfuration pathway. Glutathione levels are also low in AD. L-cysteine is required for the synthesis of glutathione. The synthesis ... -
A facile biliquid-interface co-assembly synthesis of mesoporous vesicles with large pore sizes
( Royal Society of Chemistry , 2016 , Article)In this study, novel mesoporous siliceous vesicles with ultrathin walls (50 nm in thickness) and large cavities were synthesized through a facile biliquid-interface co-assembly method by using cetyltrimethylammonium bromide ... -
A fast numerical method for ideal fluid flow in domains with multiple stirrers
( Institute of Physics Publishing , 2018 , Article)A collection of arbitrarily-shaped solid objects, each moving at a constant speed, can be used to mix or stir ideal fluid, and can give rise to interesting flow patterns. Assuming these systems of fluid stirrers are ... -
A Fitness Index model for Italian adolescents living in Southern Italy: The ASSO project
( Edizioni Minerva Medica , 2016 , Article)BACKGROUND: Strong relations between physical fitness and health in adolescents have been established in the last decades. The main objectives of the present investigation were to assess major physical fitness components ... -
A framework for optimizing the supply chain performance of a steel producer
(2013 , Conference Paper)Supply Chain Management (SCM) is focused on developing, optimizing, and operating efficient supply chains. Efficient supply chains are characterized by cost effective decisions, lean flow and structure, high degree of ... -
A Geopolitical Economy of the World Cup: Lessons from Qatar's Hosting of FIFA's Showcase Tournament
( Gulf Studies center - College of Arts & Sciences - Qatar University , 2022 , Conference Paper)Qatar's hosting of the 2022 FIFA World Cup is the embodiment of a new way in which sport in the 21st century is being conceived.
