The current study was conducted in the environment of the Martyr Monument Lake in the city center of Baghdad during 2019 to monitor the impact of climatic conditions such as drought, water shortage, high temperatures in the environment of the city and the lack of water flow during the years 2015 to 2018 and their effects on some of the physical and chemical factors of water and the dynamics of the phytoplankton community in the lake environment. Heterogeneity of some studied environmental factors, including air and water temperature, permeability, water depth, pH, DO, BOD5, nutrients, nitrate, NO3, and phosphates were found. The results showed the effect of climate change and the presence of organic pollution in addition to the influence of the nature of sites. Sampling on the studied characteristics, which in turn affected the phytoplankton community. The results showed the fluctuations in the rates of air and water temperature, which were between 17 - 41 ° C and 10 - 32 ° C, respectively, as well as the fluctuation of light transmittance rates and water depth according to the different stations and seasons, as they ranged between 0.12-57.02 cm and 120.5- 289.30cm. The pond water was characterized by being neutral and tilted to alkaline in terms of pH 7.0-9.1. The values of dissolved oxygen and vital oxygen requirement rise in winter and gradually decreased in spring and autumn, and the lowest values in summer were 2.4-15.13 mg / liter 0.4-10.6 mg / liter, respectively. The changes in nitrate values rise in winter and decreased in summer in all locations, where they ranged between 2.2 - 12.4 mg, in contrast to phosphate, it increased in the summer winter 0.0033 - 0.5 mg / liter. The qualitative study of phytoplankton identified 125 species belonging to 46 genera. It belongs to 5 classes in which the class of green algae prevailed with 69 species, followed by blue-green algae (39 species), while Euglenophyta and Pyrrophyta recorded 7 species each, while the Cryptophyta algae recorded only 3 types. The study showed that the decrease in the water level and the fluctuation of temperature led to an increase in blue-green algae in areas of organic pollution in which some species such as Microcystis aeruginosa and Oscillatoria spp. Causing the appearance of unpleasant odors and the secretion of deadly toxins to the aqueous medium.
Background: Autism is a complex developmental disability that typically appears during the first three years of life. Autism affects the normal development of the brain in the areas of social interaction and communication skills.Objectives: To identify risk factors for Autism among a sample of autistic children in Baghdad city.

Therefore, it is important to encourage usage of the constructability concept in the construction industry in Iraq. The main purpose of this study is to investigate the factors that affect constructability in Iraq and then classify them according to their importance. A total of 37 factors were collected from an intensive literature review, and they were classified under the sub and main categories. A survey was undertaken in two sessions with open questionnaire and close questionnaire. The results were analysed and the mean

Artificial intelligence has quickly invaded the realms of both creative and information-based writing, raising new questions about human originality, authorship and style. Despite its ability to produce writings that are coherent and stylistically varied, there are still concerns over the uniqueness and cultural neutrality of AI programs such as ChatGPT. This review covers significant recent advancements with artificial intelligence applications in both the literary and non-literary fields. It analyzes 35 recent studies contrasting authorship and creativity, or stylistic considerations and impressions, between human and AI texts. These studies range from poetic and fictional writing through essay, news article and academic publicati
