Koya University is located in Koy Sanjaq, near Arbil , capital of Kurdistan Region of Iraq. It was established in 2003 The university included six colleges: Engineering, Agriculture, Science, Law, Arts, and Education.Right after the uprising of March 1991 and the liberation of large parts of Iraqi Kurdistan, a climate of freedom and democracy prevailed. The long-standing dream of the Kurdish people which was seen in forming Parliament as well as Kurdistan regional government came true. Kurdistan regional government as its national duty played a vital role in setting up civil institutions generally and academic institutions specifically. In addition to developing Salahaddin University, the government began re-opening Sulaimany University and established Duhok University.Continuing to attach further importance to higher education as a topical and scientific urgency, the Kurdistan regional government opened both colleges of Education and Sharia and Law during the academic year 2000-2001 in Koya which were affiliated to Sulaimany University. Later, they became the foundation stone of Koya University with the direct support and assistance of his Excellency Mr. Jalal Talabani, Iraqi president, which led to the establishment of Koya University, promising a fresh horizon to the people of Kurdistan. Thus, on 11 October 2003 in the presence of the president, the Prime Minister, the ministers, local dignitaries, students and teachers, the foundation of Koya University was laid by Jalal Talabani.In accordance with the ministerial order issued by the Ministry of Higher Education and Scientific Research/ Private Office no.370/1/6 on 28//1/ 2004 and in compliance with the article of Council of Ministers Presidency order no. on 29 November 2003 Koya University was established for the academic year.At the end of academic year 2003-2004, the first graduation session of Koya University was held on July, 20th, 2006.

A 3D finite element model has been developed in this paper for ballistic impact on ceramic targets with three different thicknesses (4, 7,10mm) by three different nose projectiles (ogival, flat and hemispherical). The ceramic is modeled with a polynomial equation of state (EOS) using Johnson- Holmquist for the strength and JH1 for the failure model while the steel projectile is modeled with EOS shock type and Johnson-Cook Strength. This work investigates the influence of projectile head shape and the ceramic thickness on ballistic performance. It is found that the residual velocities and the amount of erosion that the projectile suffered are strongly affected by the shape of projectile head. Also the increasing the ceramic thickness leads to an increase the erosion rate and erosion amount, besides in increase in the absorbed energy.

In this work the impedance spectroscopy of α,ω-dihexyl-sexithiophene: methanofullerene; [6,6]-phenyl C61 butyric acid methyl ester (DH6T:PCBM) bulk heterojunction with and without incorporating tris (8-hydroxyquinolinate) gallium (Gaq3) was investigated in the frequency range from 50 Hz to 1 MHz. An electrical circuit was proposed to model the experimental results and to fit the data. The results showed that incorporation of Gaq3 has led to improve the interfaces between DH6T:Gaq3:PCBM moieties. The relaxation time for the Gaq3 incorporated heterojunction was found to be larger than that of the non-incorporated Gaq3 one, which implied a greater possibility for electrons and holes to transport before they relapse or recombine together. The dielectric loss in the Gaq3 incorporated DH6T:PCBM was found to be smaller than that of the non-incorporated one. This was attributed to the improved pathway for charge carriers to transport upon the addition of Gaq3. A peak in the dielectric loss was noticed for 25 % Gaq3 doped DHT:PCBM at about 106 Hz, suggesting the occurrence of dipolar relaxation. The results were analyzed and discussed based on the experimental and modelling investigations. © 2015, Springer Science+Business Media New York.

In this study we report the optical, spectroscopic, and structural properties of vacuum deposited tris (8-hydroxyquinolinate) gallium film upon thermal annealing in the temperature range from 85 °C to 255 °C under a flowing nitrogen gas for 10 min. The optical UV-vis-NIR and luminescence spectroscopy measurements were performed to estimate the absorption bands, optical energy gap (Eg), and photoluminescence (PL) of the films. Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) techniques were used to probe the spectroscopic and structural nature of the films. We show that, by annealing the films from 85 °C to 235 °C, it is possible to achieve an enhanced absorption and increased photoluminescence to five times stronger than that of the pristine film. The PL quenching at 255 °C was attributed to the presence of plainer chains allow easy going for excitons to a long distance due to the crystalline region formation of α-Gaq3 polymorph. The reduction in Eg and infrared absorption bands upon annealing were referred to the enhancement in π-π interchain interaction and conformational changes by re-arrangement of the Gaq3 quinolinate ligands, respectively. Stokes shift for the films were observed and calculated. From the differential scanning calorimetry, DSC measurements, higher glass transition temperature was observed for Gaq3 (Tg = 182 °C) compared to that of Alq3 (Tg = 173 °C), which suggests the existence of stronger dipolar interaction in Gaq3 due to the Ga3+ cation effect, in comparison to that of Alq3. © 2011 Elsevier B.V.

Natural gas is the most important and popular fossil fuel in the current era and future as well. However, because the natural gas is existed in deep underground reservoirs so it may contain several non-hydrocarbon components for example, hydrogen sulphide and carbon dioxide. These impurities are undesirable compounds and cause several technical problems for example, corrosion and environment pollution. Recently, the Iraqi Kurdistan region has achieved huge development in many fields for example, education, economic and oil and gas industry. In fact, Khurmala dome is located in southwest Erbil- Kurdistan region. The Kurdistan region government has paid great attention for this dome to provide the fuel for Kurdistan region. However, the Khurmala associated natural gas is currently flaring at the field. Moreover, nowadays there is a plan to recover and trade this gas and to use it either as feedstock to power station or to sell it in global market. However, the laboratory analysis has showed that the Khurmala natural gas has huge quantities of H2S about (5.3%) and CO2 about (4.4%). Therefore, this study aims to simulate the prospective Khurmala gas sweetening process by using the latest version of Aspen HYSYS V.7.3 program. Moreover, the simulation work is adopted amine gas sweetening process by using DEA solution and it achieved high acid gases removal for instance, H2S concentration in sweet gas stream was about 4ppm at (400m3/h) amine circulation rate. In addition, the simulation work is also achieved process optimization by using several amine types and blends for example, MEA and MDEA. It also examined some of the critical amine process factors for each amine type for example, amine circulation rate and amine concentration. Moreover, the optimization work found that the use of (DEA 35% w/w) may consider the most recommended process. © 2013 Elsevier B.V.

This work reports on the optical functions of tris(8-hydroxyquinolinate) gallium and aluminum small molecular organic films grown by utilizing a home-made thermal evaporator and studied with a spectrophotometer. The non-dispersive refractive index of the Gaq3 and Alq3 films was calculated as 1.77 and 1.68, respectively. The higher refractive index of Gaq3 was attributed to the higher molecular packing density of Gaq3 compared to that of Alq3. A larger dielectric constant for Gaq3 was noticed, indicating the presence of a higher density of states and space charge accumulation in the Gaq3 films compared to those of Alq3. We assigned the presence of direct allowed transition to energy gaps of 2.80 eV and 2.86 eV for the Gaq3 and Alq3 films, respectively. These differences are thought to be caused by the effects of central metal cations of Ga3+ and Al3+ on their molecular quinolinate ligands. © 2011 Elsevier Ltd. All rights reserved.
