On the existence of positive solutions for generalized fractional boundary value problems
(
Springer
, 2019 , Article)
The existence of positive solutions is established for boundary value problems defined within generalized Riemann–Liouville and Caputo fractional operators. Our approach is based on utilizing the technique of fixed point ...
AEO7 Surfactant as an Eco-Friendly Corrosion Inhibitor for Carbon Steel in HCl solution
(
Nature Publishing Group
, 2019 , Article)
The impact of AEO7 surfactant on the corrosion inhibition of carbon steel (C-steel) in 0.5 M HCl solution at temperatures between 20 °C and 50 °C was elucidated using weight loss and different electrochemical techniques. ...
Thermochemistry and Kinetics of the Thermal Degradation of 2-Methoxyethanol as Possible Biofuel Additives
(
Nature Publishing Group
, 2019 , Article)
Oxygenated organic compounds derived from biomass (biofuel) are a promising alternative renewable energy resource. Alcohols are widely used as biofuels, but studies on bifunctional alcohols are still limited. This work ...
Highly efficient eco-friendly corrosion inhibitor for mild steel in 5 M HCl at elevated temperatures: experimental & molecular dynamics study
(
Nature Publishing Group
, 2019 , Article)
Laurhydrazide N?-propan-3-one was used as an eco-friendly inhibitor for the corrosion of mild steel in 5 M HCl at elevated temperatures. Various electrochemical techniques and surface characterization methods were utilized ...
On Chip Optical Modulator using Epsilon-Near-Zero Hybrid Plasmonic Platform
(
Nature Publishing Group
, 2019 , Article)
In this work, we propose a micro-scale modulator architecture with compact size, low insertion loss, high extinction ratio, and low energy/bit while being compatible with the silicon-on-insulator (SOI) platform. This is ...
Generalization of best proximity points theorem for non-self proximal contractions of first kind
(
Springer International Publishing
, 2019 , Article)
The primary objective of this paper is the study of the generalization of some results given by Basha (Numer. Funct. Anal. Optim. 31:569-576, 2010). We present a new theorem on the existence and uniqueness of best proximity ...
Principal selection for Qatar's government schools: Policy makers', principals' and teachers' perspectives
(
SAGE Publications Ltd
, 2019 , Article)
Research indicates that principals are critical in school reform since the implementation of policies and practices is to a large extent determined by the role that principals play in educational change. This study examines ...

هذا نمط مهم من البحث يكاد أن يكون نادرًا أو غائبًا – في حدود ما نعلم – عن ساحة أبحاث النحو العربية. وهو يتناول بالبيان والتعليق والنقد الفصل الخاص بدراسة مظهر تراكيب العربية، الذي ورد في كتاب المستشرق أو الباحث الأمريكي ...
Potential of mercury-tolerant bacteria for bio-uptake of mercury leached from discarded fluorescent lamps
(
Academic Press
, 2019 , Article)
In this study, ten bacterial strains were found to be mercury resistant after their isolation from Qatari coastal sediments. Tolerance was found to be up to 100–150 ppm for five strains. Those strains had optimum growth ...
Probing the Solute-Solvent Interaction of an Azo-Bonded Prodrug in Neat and Binary Media: Combined Experimental and Computational Study
(
Nature Publishing Group
, 2019 , Article)
Preferential solvation has significant importance in interpreting the molecular physicochemical properties of wide spectrum of materials in solution. In this work, the solute-solvent interaction of pro-drug Sulfasalazine ...
