The aim of this paper is submitted a new approximate method for finding solution to nonlinear Lane-Emden type equations appearing in astrophysics based on modified Hermite integration operational matrix. The suggest technique is based on taking the truncated modified Hermite series of the solution function in the nonlinear Lane-Emden equation and then changed into a matrix equation with the given conditions. Nonlinear system of algebraic equation using collection points is obtained. The present method is applied on some relevant physical problems as nonlinear Lane-Emden type equations.</p> bushra Eesa Copyright (c) 2020 bushra Eesa http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1128 Sat, 27 Jun 2020 16:01:36 +0000 On some Properties of univalent function with negative coefficients by using linear operator http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1144 <p><img src="/journalsc/public/site/images/tebasabah/Capture.PNG"></p> Teba Sabah, Abdul Rahman Juma Copyright (c) 2020 Teba Sabah, Abdul Rahman Juma http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1144 Fri, 03 Jul 2020 19:27:03 +0000 QSAR, chalcones derivatives, tum Quantitative structure-activity relationship studies of series of chalcones derivatives as inhibitors of tumor necrosis factor-alpha http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1129 <p>Quantitative structure-activity relationship (QSAR) teqnique was used to predict the biological activity of a series of chalcones compounds as anti-inflammatory<strong>.</strong> 26 physicochemical descriptors are tested in QSAR equations configuration to predict biological effectiveness of compounds under study.&nbsp; The values of R<sup>2</sup> in Eqs (1–3) ranged from 0.794–0.873, the F values ranged from 14.161–26.206 and the S values ranged from 0.262–0.334. The results demonstrated excellent models based on Eq.3, along with high of R<sup>2</sup>, F and minimum S by employing three parameters <em>r</em>(C3-C5), (LUMO+1) and (LUMO+2).

The XRD analysis of the nanoparticles confirmed the formation of a tetragonal spinel structure free of unwanted phases , single-phase and transform into a cubic spinel structure when cobalt content ratio (x = 0.5). The crystalline size and lattice constants increase with increasing cobalt content there was a significant increase in the density of x-rays when the crystal structure turned into a cubic system. SEM images showed that spherical nanoparticles of pure copper ferrite films were distributed of regularly over a substrate of glass&nbsp; their crystalline size (62.25-60.0) nm, and their crystalline size&nbsp; decreased to (31.25 - 33.33) nm ,and their accumulation increases when proportion of cobalt content(x = 0.5). EDX established that nanosamples contained the elements&nbsp; Fe, Mg, Co, and O, and that there were no additional elements, and when the proportion of cobalt content increased (x = 0.5), the iron ions decreased at the tetrahedral site A. The magnetic properties of the copper ferrite&nbsp; powder were studied using the (VSM), and it was noted that the tetragonal system shifted to a cubic system when the ratio of the cobalt content (x = 0.5). The significant increase in magnetic parameters (Ms, Mr and n<sub>B</sub> (m<sub>B</sub>)) and the tightness of the hysteresis loop make it a soft magnetic material, so it can be used in high frequency magnetic equipment. The properties of optical the membranes prepared by UV-Is&nbsp; spectroscopy were studied and showed high transmittance at the percentage of cobalt content (x = 0.5) between (80-90)% in the visible and infrared region. At the ratio (x = 0.5) the energy gap and the dielectric constant increase, making it useful for devices photodetector and gas sensors.</p> Saleem Hamza Trier, Mohammed Sami Abdali Copyright (c) 2020 Saleem Hamza Trier, Mohammed Sami Abdali http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1122 Sat, 23 May 2020 02:14:15 +0000 Egg Shell powder reinforced Polypropylene (PP) composite: Effect of mechanical and heat capacity http://qu.edu.iq/journalsc/index.php/JOPS/article/view/1109 <p>The mechanical properties of Polypropylene (PP): Egg Shell powder composite was assessed with respect to the effect of filler content shells powder Egg varying from 1% to 10% by weight of the composite. Apparent amelioration in the mechanical parameters has recorded best ratios 5% and 7% weight. The mechanical properties of prepared film have examined through diverse parameters concerning the elastic deformity based on calculated the load – elongation properties. The conduct of the stress - strain curve was investigated in terms of the cold drawing model. The elastic behavior decreased at 5% composite Egg Shell powder. The specific heat capacity of Polypropylene, obvious an increase of the composite specific heat capacity using egg shell content.</p> Shaymaa H. Jasim, Wisam Alhassan, Ziyad T.
