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> Abdulhussain A.

Also, the surfaces of each nucleus were examined and nuclei were determined the symmetry.</h3> Qaissar Abdulhussein Abbas, Aamer Mose Kadem Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science http://qu.edu.iq/journalsc/index.php/JOPS/article/view/906 Sun, 20 Jan 2019 14:48:37 +0000 Study on the practices nonlinear optics with AGS and ZGP crystals http://qu.edu.iq/journalsc/index.php/JOPS/article/view/915 <h3 style="text-align: justify;">In thispaperby means of the new &nbsp;method known as Ž-Scan technique, the nonlinear optical properties for Zink Germanium Di phosphate ZnGeP<strong><sub>2</sub></strong> and Sliver Gallium Selenite (AgGase<sub>2</sub>) have been studied . 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> Raad Sh.

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> Alaa Abdelkadhim Jawad Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science http://qu.edu.iq/journalsc/index.php/JOPS/article/view/910 Fri, 15 Feb 2019 00:00:00 +0000 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 ) http://qu.edu.iq/journalsc/index.php/JOPS/article/view/911 <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).
