Synthesis, Characterization and Study the Biological Activity of Some New Heterocyclic Compounds Derived from Terephthalic Acid
...Show More Authors

The organic compound imidazole has the chemical formula C3N2H4. Numerous significant biological compounds contain imidazole. The amino acid histidine is the most prevalent. The substituted imidazole derivatives have great potential for treating a variety of systemic fungi infections. Thiourea is an organosulfur compound with the formula SC(NH2)2. It is a reagent in organic synthesis. In this paper, some new imidazole and thiourea derivatives are synthesized, characterized, and studied for their biological activity. These new compounds were synthesized from the starting material terephthalic acid, which was transformed to corresponding ester [I] by the refluxing of diacid with methanol in the presence of H2SO4 as a catalyst, compound [I] condensation with hydrazine hydrate 80% to yielded acid hydrazide [II], which was refluxed with 2 moles of various aromatic aldehydes in the presence of few drops of glacial acetic acid as a catalyst to yielded Schiff bases . Refluxing of chosen derivative with acetyl chloride in dry benzene gave new acetyl compounds which were reacted with thiourea and anhydrous sodium carbonate with acetone as a solvent to give new thiourea derivatives . Compounds were used to synthesize new imidazole derivatives by the reaction of appropriate compound with 2 moles of benzoin in dry DMF under cyclization reaction. FTIR, 1HNMR, and mass spectroscopy are used to characterize the synthesized compounds.

A THEORETICAL VISION OF THE METHODOLOGY OF MATCHING AND CONGRUENCE
...Show More Authors

Perhaps the issue of media and the press, especially one of the most common topics that people deliberate and deal with permanently and continuously. An issue of such significance has pushed researchers to put the following question, “Is it possible to live without media?”, “Can people ignore the newspaper, radio, TV, or the other communication means?”

The answer is very simple. It is difficult for civilized society to overtake information, or dispense with circulation, at the individual or collective level. Yet, the question of how to make the media and how it determines its content still requires extensive media experience; and knowledge of the social structure and its relations; and ac

Each Arab Islamic city is distinguished by its distinctive characteristics dictated by the nature of its location and its characteristics, as we see it mountainous in the mountains, deserts in the deserts, and coastal in the coasts, and this is reflected in the models of its buildings and designs and even in its structure. However, this uniqueness did not stand in the way of the emergence of characteristics and common characteristics of these cities over time, the factors derived from the core of the life of the community habits and traditions and beliefs and living requirements and environmental conditions that all piled in the process of building and construction of the Arab Islamic city to draw The features and lines of life of the co

Assessing of the Morphology and Sediment Transport of Diyala River
...Show More Authors

 

Diyala River is one of the important rivers that provide water for the Governorate of Diyala. In this research, the morphology and sediment transport of this river were studied using HEC-Ras software. The selected length of the river in the present study is 193 km and extended from Diyala Weir to the confluence of Tigris River and Diyala River. The fieldwork period extended from June 2020 till August 2020, where suspended-load and bed-load samples were collected and surveyed some cross-sections. The one-dimensional sediment transport model has been calibrated for five years, from 2014 to 2019. The results were compared with the measured cross-sections in 2019,  and the suitable value of (maximum depth
