Calculation of the structural properties of a strange quark star in the presence of a strong magnetic field using a density dependent bag constant

引用

Research in Astronomy and Astrophysics 2012年第9期12卷 1280-1290页

作者： Gholam Hossein Bordbar hajar Bahri Fatemeh Kayanikhoo Department of Physics Shiraz University Shiraz 71454 Iran Research Institute for Astronomy and Astrophysics of Maragha P.O. Box 55134-441 Maragha Iran

We have calculated the structural properties of a strange quark star with a static model in the presence of a strong magnetic field. To this end, we use the MIT bag model with a density dependent bag constant. To parameterize the density dependence of the bag constant, we have used our results for the lowest order constrained variational calculation of the asymmetric nuclear matter. By calculating the equation of state of strange quark matter, we have shown that the pressure of this system increases by increasing both density and magnetic field. Finally, we have investigated the effect of density dependence of the bag constant on the structural properties of a strange quark star.

A Distance Function for Computing on Finite Subsets of Euclidean Spaces

Acta Mathematicae Applicatae Sinica 2018年第1期34卷 197-208页

作者： hajar Ghahremani-Gol Farzad Didehvar Asadollah Razavi Department of Mathematics Faculty of Science Shahed University Tehran *** Iran Department of Mathematics and Computer Science Amirkabir University of Technology 424 Hafez Av Tehran *** Iran Department Pure Mathematics Faculty of Mathematics and Computer Science Shahid Bahonar University of Kerman Kerman Iran

In practical purposes for some geometrical problems, specially the fields in common with computer science, we deal with information of some finite number of points. The problem often arises here is： “How are we able to define a plausible distance function on a finite three dimensional space？” In this paper, we define such a distance function in order to apply it to further purposes, e.g. in the field settings of transportation theory and geometry. More precisely, we present a new model for traveling salesman problem and vehicle routing problem for two dimensional manifolds in three dimensional Euclidean space, the second problem on which we focus on this line is, three dimensional triangulation.

作者： Mohammad Bayat Hossien Imanieh Seydeh hajar Hossieni Chemistry Department Imam Khomeini International University

The reaction of dimedone with various aromatic aldehydes produces 2,2＇-arylmethylene bis （3-hydroxy-5,5-dimethyl-2- cyclohexene-l-one） in excellent yields. The reactions occur in water as solvent at room temperature and avoiding the addition of any catalyst. The workup procedure is very simple and the products do not required further purification.
