The chemical bath deposition technique (CBD) is considered the cheapest and easiest compared with other deposition techniques. However, it is highly sensitive to effective parameter deposition values such as pH, temperature, and so on. The pH value of the reaction solution has a direct impact on both the nucleation and growth rate of the film. Consequently, this study presents a novel investigation into the effect of a precise change. in the pH reaction solution value on the structural, morphological, and photoresponse characteristics of tin monosulphide (SnS) films. The films were grown on a flexible polyester substrate with pH values of 7.1, 7.4, and 7.7. The X-ray diffraction patterns of the grown films at pH 7.1 and 7.4 confirmed their polycrystalline nature. Additionally, an observed alteration in the crystal structure occurred as the pH value increased from 7.1 to 7.4, resulting in a transition from an orthorhombic crystal structure to a cubic crystal structure. In contrast, the XRD pattern of the grown film at pH 7.7 revealed that it was amorphous. The field-emission scanning electron microscopy images revealed a flower-like morphology for the grown film at 7.1, whereas the grown films at 7.4 and 7.7 revealed a grain morphology. The results also showed that the pH values were also having an important effect on the energy gap value (Eg ) of films; the Eg values were 1.46, 1.57, and 1.65 eV for pH 7.1, 7.4, and 7.7, respectively. The photodetectors fabricated using grown films exhibited excellent photoresponse characteristics. when subjected to near-infrared (750 nm) illumination. It was also demonstrated that the photodetector using. the cubic structure film possessed faster response times and greater sensitivity than the photodetector using the orthorhombic structure film.

Henrik Ibsen is considered one of the greatest writers on society and its problems in the modern era, as his works deal with society in all its forms in a realistic way, in which he presents the motives and consequences of social problems and their impact on society to study these problems through them to and propose solutions through theatre. Most of his writings were very serious about addressing these social issues. The method of collecting information in the study came through reviewing a group of sources related to realistic theater and social theory, then reading the plays covered in a critical and analytical reading. Based on that, the method of writing this study came and used a group of sources that directly relate to the s

Various literary studies have investigated the psychological, social and cultural effects of traumatic events. They give voice to traumatised victims and enable them to convey and confront their traumas. However, these studies present a one-sided view, concentrating largely on the presentation of trauma in the industrial societies of the Western world. Recently, increasing attention has been devoted to identifying and depicting the forms and types of trauma that have been experienced in marginalised and neglected societies, such as the Iraqi society. Iraq has witnessed the unexpected fall of a brutal dictatorship, Western invasion and an unprecedented rise of sectarian discourses. This extreme violence has deeply affected many aspec

The research dealt with the role of artificial intelligence applications in accounting education at the University of Applied Sciences as a model for Bahraini universities to achieve sustainable development goals. The application of artificial intelligence in accounting education achieves seven of the seventeen sustainable development goals. It also concludes that there is an artificial intelligence infrastructure in the Kingdom of Bahrain, as it occupies a leading regional position in digital transformation, as Bahrain ranks first in the Arab world i

The study aims to: examine the historical roots of social work in the Iraqi society, investigate the objectives of the developmental role of social work, review the theories of social extremism, its characteristics, and causes, and to analyze the developmental role of social work to limit social extremism. To meet the objectives of the study, a descriptive analytical approach has been adopted. It involves using the social sampling survey method, i.e., a questionnaire tool in the University of Baghdad community-College of Media.

These sites can provide a powerful means of sharing, organizing, finding information and knowledge. The popularity of these sites provides an opportunity to measure the use them in knowledge sharing, which needs a special scale, but unfortunately, there is no special scale for that. Thus, this study supposes to use SCT as a scale to measure the use of SMNs in electronic knowledge sharing due to it has been used to measure knowledge sharing with its traditional form.
