Behavior of Anisotropic Compact Stars in f(R,∅) Gravity

引用

Communications in Theoretical Physics 2019年第5期71卷 599-609页

作者： m.Farasat Shamir Adnan malik Department of Sciences and Humanities National University of Computer and Emerging Sciences

The aim of this paper is to investigate modified f(R, ?) theory of gravity, where R and ? represent the Ricci scalar and scalar potential respectively. Specifically, we take the spherically symmetric spacetime to discuss the possible emergence of compact stars. We study the physical behavior of compact stars by considering 4 U 1820-30, SAX J1808-3658 and Her X1, which are three popular models of compact stars. The graphical analysis of energy density, radial pressure, tangential pressure, energy conditions as well as stability of compact stars has been shown. It is concluded that behavior of these three stars is usual for f(R, ?) gravity models with some specific choices of model parameters.

Exact solutions of mHD second Stokes flow of generalized Burgers fluid

引用

Applied mathematics and mechanics(English Edition) 2015年第2期36卷 211-224页

作者： m.KHAN R.malik A.ANJUm Department of mathematics Quaid-i-Azam University

This work concerns with the exact solutions of magnetohydrodynamic（mHD）flow of generalized Burgers fluid describing the second Stokes problem. The modified Darcy law is taken into account. The related velocity distribution and shear stress are expressed as a combination of steady-state and transient solutions computed by means of integral transformations. The effects of various parameters on the flow field are investigated. The mHD flow results in reduction of velocity distribution and associated thickness of the boundary layer.

The interaction of cationic gemini surfactants(alkanediyl-α,ω-bis(alkyl dimethylammonium bromide)) with an antipsychotic drug(chlorpromazine hydrochloride(CPZ)) has been investigated. Various micellar and interfacial parameters have been deliberated by surface tension measurement to report the nature of interactions between drug and novel surfactant mixtures. The behavior of mixed systems, their compositions and activities of components have been analyzed in the light of Rubingh's theory. The results indicate synergism in the binary *** binding study between CPZ and surfactants has been done by spectroscopic techniques such as UV–visible and fluorescence. The results are discussed in the light of the use of gemini surfactants as promising drug delivery agents for phenothiazine drugs, and hence, improve their bioavailability.

Peristaltic Flow of Shear Thinning Fluid via Temperature-Dependent Viscosity and Thermal Conductivity

引用

Communications in Theoretical Physics 2019年第4期71卷 367-376页

作者： S.Noreen A.malik m.m.Rashidi Department of mathematics COMSATS University Islamabad Shanghai Automotive Wind Tunnel Center Tongji University

In this paper Williamson ?uid is taken into account to study its peristaltic ?ow with heat effects. The study is carried out in a wave frame of reference for symmetric channel. Analysis of heat transfer is accomplished by accounting the effects of non-constant thermal conductivity and viscosity and viscous dissipation. modeling of fundamental equations is followed by the construction of closed form solutions for pressure gradient, stream function and temperature while assuming Reynold's number to be very low and wavelength to be very long. Double perturbation technique is employed, considering Weissenberg number and variable ?uid property parameter to be very small. The effects of emerging parameters on pumping, trapping, axial pressure gradient, heat transfer coe?cient, pressure rise,velocity pro?le and temperature are analyzed through the graphical representation. A direct relation is observed between temperature and thermal conductivity whereas the indirect proportionality with viscosity. The heat transfer coe?cient is lower for a ?uid with variable thermal conductivity and variable viscosity as compared to the ?uid with constant thermal conductivity and constant viscosity.

Numerical Analysis of Unsteady magneto-Biphase Williamson Fluid Flow with Time Dependent magnetic Field

Communications in Theoretical Physics 2019年第2期71卷 143-151页

作者： madiha Bibi m.Y.malik A.Zeeshan Department of mathematics College of Sciences P.O.Box 9004 King Khalid University Department of mathematics Quaid-I-Azam University Department of mathematics and Statistics Faculty of Basic and Applied Sciences International Islamic University

Numerical investigation of the dusty Williamson fluid with the dependency of time has been done in current disquisition. The flow of multiphase liquid/particle suspension saturating the medium is caused by stretching of porous surface. The influence of magnetic field and heat generation/absorption is observed. It is assumed that particle has a spherical shape and distributed uniformly in fluid matrix. The unsteady two-dimensional problems are modeled for both fluid and particle phase using conservation of mass, momentum and heat transfer. The finalized model generates the non-dimensioned parameters, namely Weissenberg number, unsteadiness parameter, magnetic parameter,heat generation/absorption parameter, Prandtl number, fluid particle interaction parameter, and mass concentration parameters. The numerical solution is obtained. Locality of skin friction and Nusselt number is deliberately focused to help of tables and graphs. While inferencing the current article it is clearly observed that increment of Williamson parameter, unsteadiness parameter, magnetic parameter, volume fraction parameter, and mass concentration parameter reduces the velocity profile of fluid and solid particles as well. And increment of Prandtl number, unsteadiness parameter,volume fraction parameter, and mass concentration parameter reduces the temperature profile of fluid and solid particles as well.

Regime dynamics of hydrochemical and toxicological parameters of the Irtysh River in Kazakhstan

Journal of Arid Land 2016年第4期8卷 521-532页

作者： Diana m BURLIBAYEVA malik Zh BURLIBAYEV Christian OPP BAO Anming Department of Water Resources and Land Reclamation Kazakh National Agrarian UniversityAlmaty 050010Kazakhstan Kazakhstan Agency of Applied Ecology Almaty 050012Kazakhstan Department Hydrology&Soil Science Faculty of GeographyPhilipps UniversityMarburg 35032Germany Xinjiang Institute of Ecology and Geography Chinese Academy of SciencesUrumqi 830011China

Since the Irtysh River flows through the important economic, ecological and social territories of China, Kazakhstan and Russia, the water quality issues growingly draw the attention of the water authorities from these countries. Therefore, a detailed study of the hydrochemical regime and toxicological indicators in Kazakhstan was carried out for understanding the regime dynamics of water quality and its affect factors. The combined assessment of maximum permissible concentration （mPC） of chemical components and biotesting method were proposed and performed for the study area. The results clearly showed that the concentrations of single chemical component at different locations are mostly under mPC standard in a basin scale. However, the watershed surface runoff and tributary stream flow from mining industry areas had high concentration of heavy metals and had significant impact on the water quality near Ust-Kamenogorsk. Furthermore, even the stream water generally meet mPC standard, the results of biotesting method show the toxicity level of water sample is lethal for the test objects of phytoplankton and Daphnia. The survival rates of most water samples are lower than 46.7%. Hereby, this study strongly suggests using combined water assessment methods to evaluate the water quality.
