Synthesis, Characterization of Different Five-Membered Heterocyclic Derivatives, Evaluated Their as Antioxidant, and In Vitro Antimicrobial Agents
...Show More Authors

Objective:This study involved synthesis of a new series of different five-membered heterocyclic derivatives, testing their antioxidant activity, and examining their potential in vitro antimicrobial agents. Methods: The synthesis of the derivatives involved a three-step process. Initially, succinyl chloride was reacted with methanol, followed by a reaction with 80% hydrazine hydrate through a nucleophilic addition-elimination mechanism, resulting in the formation of succinohydrazide (I). This compound was then employed as a precursor for the synthesis of Schiff bases (II), and (III) by reacting it with m-nitro benzaldehyde and p-nitro benzaldehyde. Following this, a ring closure reaction was applied using thioglycolic acid, glycolic acid, and glycine, resulting in the synthesis of different five-membered heterocyclic rings (IV–IX). Results and Discussion: The formation of the prepared derivatives was confirmed by FT-IR, 1H NMR, and 13C NMR spectroscopy. Comparative analysis with L-ascorbic acid as a standard revealed that all the prepared compounds exhibited excellent antioxidant activities. In terms of antimicrobial activity, the tested derivatives showed moderate activity against both positive and negative types of bacteria, when compared to the reference drug Ciprofloxacin. Additionally, the antifungal test showed moderate activity for all the tested compounds against a specific pathogenic fungus, with Clotrimazole being as the reference drug. The antimicrobial activity of the synthesized compounds was found to be dependent on the type of heterocyclic rings containing S, O, and N atoms. These atoms were observed to enhance antimicrobial activity by donating electrons and becoming active. Additionally, the presence of active functional groups such as C=O, NO2, and C=N contributed to this observed result. Conclusions: All of the synthesized compounds have demonstrated excellent antioxidant agents. Most of them have shown promising antimicrobial activity against certain bacteria strains, and effectiveness against a pathogenic fungus.

A comparative Analytical Investigation of Different Geomagnetic Storms During Solar Cycles 23 and 24
...Show More Authors
Abstract<p>In this work, the geomagnetic storms that occurred during solar cycles 23 and 24 were classified based on the value of the Disturbance Storm Time index (Dst), which was considered an indicator of the strength of geomagnetic conditions. The special criterion of Dst >-50 nT was adopted in the classification process of the geomagnetic storms based on the minimum daily value of the Dst-index. The number of geomagnetic storms that occurred during the study period was counted according to the adopted criteria, including moderate storms with (Dst >-50 nT), strong storms with (Dst >-100 nT), severe storms with (Dst >-200 nT), and great storms with (Dst >-350 nT). The statistica</p> ... Show More

The semiology of culture and the sign variable in a theatre performance: Iraqi theatre as an example
...Show More Authors

The culture of theatre performance has a vital role in the process of reading the linguistic and visual signs of the performance. And the process of transforming a theatre performance from its original context into a new hosting cultural context starts from the actual reading of the text. Directors derives their new signs out of his personal culture, depending on the society where they lives and the culture that forms the social conventions, traditions and beliefs. The text is usually written within its own historical and temporal culture. The process of its production usually takes it away from its original culture, when it interprets the codes of the original writer and their visual and linguistic signs and instils new alternative sign

The problem of employing political discourse and its role in promoting community peace: Iraq as a model
...Show More Authors

After 2003, Iraq witnessed new challenges represented by the predominance of sectarian discourses, hatred and extremism at the expense of moderate political discourse and the predominance of sub-affiliations and external agendas at the expense of national affiliation, which led to the creation of an unsafe or stable environment dominated by the character of violence and terrorism. Moderate discourse would work to fuse sub-affiliations into one melting pot in which it would be the first loyalty to the homeland and not to the tribe, party or sect... Etc., and this in turn will contribute to promoting peaceful coexistence between the various other sub-affiliations within the framework of one community construction

Effect of arbuscular mycorrhizal fungi as a biocontrol agent and organic matter against fusarium wilt in tomato
...Show More Authors

The objective of this investigation was to study the effects of a mixture of three arbuscular mycorrhizae (Glomus etunicatum, G. leptotichum and Rhizophagus intraradices) on the development of fusarium wilt disease in tomato plants in the presence and absence of organic matter (peatmoss). Results indicated an increase in mycorrhizal root dry weight especially in the presence of the organic matter, on the other hand this parameter was significantly decreased when Fusarium oxysporum f. sp. Lycopersiciwas added simultaneously with the mycorrhiza, Moreover, mycorrhiza and organic matter significantly reduced the damping off seedling disease, disease severity and rate of infection of tomato leaves and roots caused by the pathogenic fungus, These
