Finally,the electron temperature and plasma density wereexamined by employing a spectroscopy. The electron temperature was measured throughcalculating approximatelyintensity's ratio of two lines.Via the conditions that the inner cylinder diameter was R = (3&amp;6) cm; HCD supply voltage, (300-900) V.Also, a study of effect of gas pressure and voltage change along plasma discharging was done and the temperature of electron for plasma estimated spectrally between (0.8-1.3) eV and the density of electrons (2.8x10<sup>15</sup>-7x10<sup>17</sup>) cm<sup>-3</sup></h4> 2019-01-20T13:57:49+00:00 Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science STUDY OF ENERGY LEVELS, QUADRUPLE ELECTRIC TRANSITION PROBABILITIES AND POTENTIAL ENERGY SURFACE FOR ISOTOPES 62-60 ZN USE IBM-1 2019-04-22T06:17:54+00:00 Qaissar Abdulhussein Abbas Aamer Mose Kadem <h3 style="text-align: justify;">&nbsp;&nbsp; &nbsp;The aims of this study to the properties of the nuclear structure of isotopes light (62 Zn, 60Zn) using the first interactive boson model (IBM-1) Low energy levels of determination were determined by the type of dynamic symmetry of these isotopes (62 Zn, 60Zn) Similar to some of the energy levels that were not definitively identified and some were confirmed and the momentum and symmetry of others that were not previously identified in practice. Also, the surfaces of each nucleus were examined and nuclei were determined the symmetry.</h3> 2019-01-20T14:48:37+00:00 Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science Study on the practices nonlinear optics with AGS and ZGP crystals 2019-04-22T06:17:10+00:00 Raad Sh.

Ž-scan experience was doneby laser called Nd-yag at 532 nm and 1064 nm and output of (80,40 ,35 and 25) mW, in two parts. The first one was a closed-aperture placed ahead of the detector to calculate the index of nonlinear refractive. While the second part; the aperture ahead the detector was taken away (open manhole) to calculatethecoefficient of nonlinear absorption. The experiential outcomes exhibit&nbsp; that the Sliver Gallium Selenite (AgGaSe<strong><sub>2</sub></strong>) exhibits positive refractive index (self-focusing) and saturation absorption, while the experimental results for Zink Germanium Di phosphate ZnGeP<strong><sub>2</sub></strong> exhibits negative nonlinear refraction(self-defocusing)and two-photon absorption.</h3> 2019-02-21T00:00:00+00:00 Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science ESTIMATING PARETO DISTRIBUTION PARAMETERS OF TYPE I 2019-04-22T06:17:41+00:00 HADIR H SHUBBAR <p>Some of methods like (Moment Method, Maximum Likelihood Method, Term Omission Method) are selected in this paper to estimate the parameters of Pareto (Type I) using simulation of different sample sizes (n=50, 100, 200).

A total of &nbsp;25 stool samples were collected and subjected to the above mentioned techniques. The results of the TBI revealed the presence of <em>S</em>. <em>flexneri</em> in these samples. The PCR results confirmed the identification of these bacteria in these samples after a piece, 1256 bp, of the <em>gyrB</em> gene, encodes the subunit B protein of DNA gyrase, was targeted. For the sequencing of 2 samples, the results showed the complete confirmation revealing the correctness of the TBI and the PCR results in identifying these bacteria in the tested samples. The PTA revealed separate distinctive clustering of the sequenced samples in one branch of the phylogenetic tree. The current study enhances the documentation that <em>S</em>. <em>flexneri</em> is one of the infectious agents that causes GIT-related infections in the current tested city.</h4> 2019-02-15T00:00:00+00:00 Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science Synthesis and characterization of some complexes of Co(II), Ni(II), Cu(II),Zn(II),Cd(II) and Hg(II) with Schiff–base( N-benzylidine furan -3-Carbohydrazide ) 2019-04-22T06:17:27+00:00 Janan Idress Mohammed Shaheen <h4 style="text-align: justify;">A new complexes of general formula [M(R)<sub>2</sub>] (NO<sub>3</sub>)<sub>2</sub>] where M= Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II), are synthesized by the coordination of these metal salts with Schiff-base [N-benzylidine furan-3-carbohydrazides (RH)].The Schiff base is prepared by condensation of&nbsp;&nbsp; Furan -3-carbohydrazide and 2-hydroxy benzaldehyde (1 : 1 molar ratio).
