Exploring the stability of HEXACO-60 structure and the association of gender, age, and social position with personality traits across 18 countries
( John Wiley and Sons Inc , 2022 , Article)Objectives: The present paper tests the cross-national stability of the HEXACO-60 structure across 18 countries from four continents. Gender and age differences across countries will be examined. Finally, this is the first ... -
Dark Triad Traits, Social Position, and Personality: A Cross-Cultural Study
( SAGE Publications Inc. , 2022 , Article)This research explores the Dark Triad traits in 18 cultures from Europe, America, Africa, and Asia. We examined the relationships among Dark Triad traits, as measured by the SD3, with gender, age, social status, and two ... -
A Comparison between Different Agro-wastes and Carbon Nanotubes for Removal of Sarafloxacin from Wastewater: Kinetics and Equilibrium Studies
( Multidisciplinary Digital Publishing Institute (MDPI) , 2020 , Article)In the current study, eco-structured and efficient removal of the veterinary fluoroquinolone antibiotic sarafloxacin (SARA) from wastewater has been explored. The adsorptive power of four agro-wastes (AWs) derived from ... -
On the Lp boundedness of rough parametric Marcinkiewicz functions
( Victoria University of Technology , 2007 , Article)In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]). © ... -

On the boundedness of rough oscillatory singular integrals on Triebel-Lizorkin spaces
( springer link , 2011 , Article)We obtain appropriate sharp bounds on Triebel-Lizorkin spaces for rough oscillatory integrals with polynomial phase. By using these bounds and using an extrapolation argument we obtain some new and previously known results ... -
Weighted estimates for oscillatory singular integrals
(2013 , Article)We establish uniform bounds for oscillatory singular integrals as well as oscillatory singular integral operators. We allow the singular kernel to be given by a function in the Hardy space H1(Sn-1), while such results were ... -
Rough oscillatory singular integrals on ℝⁿ

Boundedness of rough integral operators on triebel-lizorkin spaces
( Universitat Autonoma de Barcelona, Seccio de Matematiques , 2012 , Article)We prove the boundedness of several classes of rough integral operators on Triebel-Lizorkin spaces. Our results represent improvements as well as natural extensions of many previously known results. -
Electrospun Polysulfone Hybrid Nanocomposite Fibers as Membrane for Separating Oil/Water Emulsion
( Springer Nature , 2023 , Article)Commercial polymer membranes are largely utilized to separate oil/water mixtures; however, membrane fouling, flux decline, and short lifetime often inhibit their high performance. In order to resolve these drawbacks of the ... -
Regulatory Mechanisms That Guide the Fetal to Postnatal Transition of Cardiomyocytes
( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)Heart disease remains a global leading cause of death and disability, necessitating a comprehensive understanding of the heart’s development, repair, and dysfunction. This review surveys recent discoveries that explore the ... -
A cross-sectional analysis of zinc and copper levels and their relationship to cardiovascular disease risk markers in Qatar biobank participants
( Frontiers Media , 2023 , Article)Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity worldwide. Dietary intake, particularly zinc (Zn) and copper (Cu) has been strongly associated with CVD. These trace elements play a crucial ... -
