ZnO Characterization of ZnO/GaAs heterojunction: ZnO thin films
...Show More Authors

ZnO thin films have been prepared by pulse laser deposition technique at room temperatures (RT). These films were deposited on GaAs substrate to form the ZnO/GaAs heterojunction solar cell. The effect of annealing temperatures at ( RT,100, 200)K on structural and optical properties of ZnO thin films has been investigated. The X-ray diffraction analysis indicated that all films have hexagonal polycrystalline structure. AFM shows that the grains uniformly distributed with homogeneous structure. The optical absorption spectra showed that all films have direct energy gap. The band gap energy of these films decreased with increasing annealing temperatures.  From the electrical properties, the carriers have n-type conductivity.  From C-V measurement of ZnO/GaAs heterojunciton solar cell at frequency 100, 200 KHz, It is found that built–in potential (Vbi) increases with increase frequency. Also, from I-V characteristic it is observed that the ideality factor is 2.7. Short-circuit current (Isc) is 4.0mA/cm2, open circuit voltage (Voc) is 0.5V, fill factor ( F.F) is 0.7  and the efficiency is about 6.0 %.

The function of Feng Shui’s five elements in encouraging urban public space for social interaction. Case study: Al-Arabi and Al-Washash neighborhoods in the Al-Mansour district, Baghdad
...Show More Authors

Motives: This study examines the integration of Feng Shui principles into urban public spaces to enhance social interaction, livability, and environmental harmony. The case study focuses on the Al-Arabi and Al-Washash neighbourhoods in Baghdad, exploring how spatial characteristics influence engagement and energy circulation (Qi) within the urban network. The motivation arises from deficiencies in connectivity, shading, greenery, and water features, which limit social and aesthetic vibrancy. Aim: The objectives are to evaluate spatial and social dynamics through the Feng Shui Public-Space Index (FS-PSI), Space Syntax analysis, and resident surveys, and to propose strategies using Feng Shui design proxies to improve energy flow, acce

The morphological structure of nouns and verbs in the novel "Astonishment" by the novelist Aharon Applefield, Morphological study.: מבנה שמות עצם והפעלים ברומן תימהון לסופר אהרון אפלפלד עיון מורפולוגי
...Show More Authors

This research sheds light on the morphological structure of nouns and verbs in the novel "ASTONISHMENT" by the novelist Aharon Applefield by analysing selected models from the novel in a morphological analysis in order to identify the most important morphological features of this structure according to a statistical analytical approach.

 The morphological structure is the main pillar of the linguistic structure of the literary text. Morphology is the science that studies the word, by which its structure and original letters are known, and the change that has occurred to it.  The aesthetics of the fictional text is reflected in this structure, through which the writer conveys his ideas and narrations to the reader.  The research

Background: This research identified Streptococci spp. depending on culture, biochemistry, the VITEK technique, ability to produce biofilms, and antibiotic resistance. Aim: The goal of this study was to perform microbiological procedures to evaluate the qualitative qualities of mozzarella cheese against infective Streptococci using microbiological care. Methods: Sixty (60) mozzarella cheese samples were brought from diverse markets in Baghdad from October 2023 to December 2023 at the Zoonoses Research Unit and Veterinary Public Health Department, Veterinary Medicine College, University of Baghdad. Culture of samples on agar (MacConkey and blood) and aerobically incubated at 37°C for 48 hours. Gram staining purified colonies to
