برای گروه متناهی ‎$g$‎، فرض می‎‎کنیم ‎$cent(g)$‎ نشان دهنده مجموعه مرکز سازهای تک عضوی های ‎$gin g$‎ باشد. ‎$g$‎ را ‎$n$‎- مرکز ساز گوئیم هرگاه ‎$|cent(g)|=n$‎ باشد. در این پایان‎ نامه مقدار ‎$|cent(g)|$‎ را برای برخی از گروه های متناهی ‎$g$‎ محاسبه می کنیم و نشان می دهیم که برای هر عدد صحیح مثبت ‎$n eq 2,3$‎ ، گروه متناهی با ‎$|cent(g)|=n$‎ موجود است. ساختار گروه متناهی ‎$g$‎ با ‎$|cent(...

The object of this paper is to establish certain generalized fractional integration and differentiation involving generalized Mittag-Leffler function defined by Salim and Faraj [25]. The considered generalized fractional calculus operators contain the Appell's function $F_3$ [2, p.224] as kernel and are introduced by Saigo and Maeda [23]. The Marichev-Saigo-Maeda fractional calculus operators a...

Assume that $mathbb{D}$ is the open unit disk. Applying Ozaki's conditions, we consider two classes of locally univalent, which denote by $mathcal{G}(alpha)$ and $mathcal{F}(mu)$ as follows begin{equation*}  mathcal{G}(alpha):=left{fin mathcal{A}:mathfrak{Re}left( 1+frac{zf^{prime prime }(z)}{f^{prime }(z)}right) <1+frac{alpha }{2},quad 0<alphaleq1right}, end{equation*} and begin{equation*}  ma...

PROF. MOHAMMED YUNUS, DR.J. FAZLUR RAHMAN Abstract— Ceramic coated components have the advantage features of both metal and ceramics, i.e. good toughness, high hardness and wear resistance. Despite their outstanding characteristics, ceramic materials are not used in many cases due to high cost of machining. A major draw back to engineering applications of ceramic is due to their brittleness and...

Background: Enterococci are important gram-positive bacteria causing dental calculus in human beings; however, the role of these bacteria in oral cavity is unclear. The aim of this study was to investigate the presence of Enterococcal Surface Protein (esp) gene in Enterococcus faecalis isolated from dental calculus in the city of Sari, Iran. Materials and Methods: In the present study, 207 den...

The Euler-Lagrange equation plays an important role in the minimization problems of the calculus of variations. This paper employs the differential transformation method (DTM) for finding the solution of the Euler-Lagrange equation which arise from problems of calculus of variations. DTM provides an analytical solution in the form of an infinite power series with easily computable components. S...
