A 6th-order local approximation by a cubic curve
( Qatar University , 1997 , Article)We derive and present a MAPLE program for the construction of a parametric cubic polynomial curve which has sixth-order contract with a given smooth curve at a given point, thus providing a local sixth-order approximation ... -
A best proximity point theorem for special generalized proximal ?-quasi contractive mappings
( Springer , 2019 , Article)In this paper, we obtain some best proximity point results for a new class of non-self mappings T: A? B called special generalized proximal ?-quasi contractive. Our result is illustrated by an example. Several consequences ... -
A boundary integral method for the general conjugation problem in multiply connected circle domains
( Springer International Publishing , 2018 , Article)We present a boundary integral method for solving a certain class of Riemann-Hilbert problems known as the general conjugation problem. The method is based on a uniquely solvable boundary integral equation with the generalized ... -
A comparative study of chemically reacting 2D flow of Casson and Maxwell fluids
( Elsevier B.V. , 2018 , Article)Theoretical investigation is performed to discuss the heat and mass transfer behavior of chemically reacting magnetohydrodynamic Casson and Maxwell fluids past a stretching sheet with Brownian moment and thermophoresis ... -
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 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 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 ... -
