Effect of Secondary Metabolite Crude of Metarhizum anisopliea Fungus on the Second Larval Stage of the Housefly Musca domestica
...Show More Authors

         The house flies Musca domestica )Diptera:musidae) are the primary carrier of many pathogens such as cholera, typhoid, anthrax, and others. The use of chemical pesticides as a basic method of control leads to many problems at the environmental and health level. The use of safe alternatives to chemical pesticides has become an urgent necessity. The research aims to find biological alternatives that are environment-friendly and non-pathogenic to humans in controlling house flies through the possibility of extracting and diagnosing some secondary metabolites produced by the fungus Metarhizium anisopliae and testing their effects on the second larval stage of house flies using different treatment methods that include direct spraying of the larvae, treating the food environment, and the dipping method. Secondary metabolites and toxins of Metarhizium anisopliae were extracted in liquid media PDB using a mixture of organic solvents such as ethyl acetate and methanol. The secondary metabolites were identified by gas chromatography-mass spectrometry (GC-MS). The results showed the identification of 10 chemical compounds, including phenol, 2,4-bis(1,1-dimethylethyl (C14H22O)., Diethyl Phthalate (C12H14O4),  Hexadecanoic acid, methyl ester (C17H34O2 ),  Phthalic acid, butyl undecyl ester (C23H36O4) , 9,12-Octadecanoic (Z,Z )-, methyl ester ( C19H34O2),  9-Octadecanoic acid, methyl ester, (C19H36O2), 9,12,15-Octadecanoic acid,methyl ester,(Z,Z,Z) (C19H32O2), Octadecanoic acid,methyl ester(C19H38O2), Oleic Acid (C24H38O4), 9-Octadecanoic acid (Z)-,2-hydroxyl (hydroxymethyl) ethyl ester(C21H40O4) ,and Di-n-octyl phthalate (C24H38O4 ). The results showed that the crude extract of the fungus cause the best mortality rate  in the second instar larvae at concentrations of 3 and 5% after 72 hours of treatment when  the mortality rates ranged between 60-100%. The mortality rates were directly proportional to the increase in concentration and time with a significant difference. The results also showed that the treatment of the food media was the most effective in affecting the larvae of flies, recording mortality rates that reached 100%, with a significant difference with direct spraying and dipping methods. These results reveal the significant efficacy of the tested secondary metabolite crude of m.anesopalae against Musca domestica which could be used as an ecofriendly alternative for insect control.

Study the Effect of different doses of Rapamycin on the liver development in the Swiss Albino Mice Embryos
...Show More Authors

The current study, which extended from February 2020 to June 2021 at the University of Thi- Qar\ College of Education for Pure Sciences, aimed to follow the changes in external morphological features at different Embryonic Developmental stages in pregnant mice treated with different doses of Rapamycin (Rapa). Use In this study, 32 pregnant mice were divided randomly into four groups, each of which had eight pregnant mice. Each group received different dose of Rapa via intraperitoneally injection at different gestation days until the end of the specified periods, whereas the control group received a DMSO. Mice were administered under the same circumstances and dosages were determined based on body weight, as specified in pharmaceutical const

The Effect of the Natural and Cultural Environments Factors on the Architectural and Planning Characteristics of Sulaymaniyah Mosques
...Show More Authors

Most of the mosques in the Islamic world fall under specific and known forms and patterns to a large extent, and such patterns have grown and evolved from the few basic and uniform models, but they changed slowly due to the impact with a mixture of changing functional requirements and cultural landscapes because of the variables of time and place to form patterns known and famous in this day across parts of the Islamic world and its borders. There was no exception to these patterns, but small numbers of mosques that were probably the result of personal experiences or improvisational resolutions, or in response to specific or temporary stimuli. However, the emergence of a specific pattern which does not belong to any of these patt

Study the Effect of the High Voltage on The preparation of Polyvinyl Alcohol/ Tio2 Nano Fiber by Electrospinning
...Show More Authors

Abstract:In this research we prepared nanofibers by electrospinning from poly (Vinyl Alcohol) / TiO2. The spectrum of the solution (Emission) was studied at 772 nm. Several process parameter were Investigated as concentration of PVA, the effect of distance from nozzle tip to the grounded collector (gap distance), and final the effect of high voltage. We find the optimum condition to prepare a narrow nanofibers is at concentration of PVA 16gm, the fiber has 20nm diameter.

The effect of Acculturation on the Plans of Iraqi Origin Elites during the Late Ottoman Rule (1830-1917)
...Show More Authors

Generally, different propositions show that culture changes because of many factors, and acculturation has emerged out of important operations which lead to cultural change as a result of contact between different societies or cultures. Since the cultural environment with its varying effects plays a major role in the formulation of architectural products, the research defined its research problem as follows: There is need for knowledge to specify the results of acculturation at  the level of plans of house architecture belong to Iraqi elites in Baghdad city during the late Ottoman rule in Iraq(1830-1917). The research depends on the comparative procedure to define the acculturation results, so the plans character of

The effect of a psychological scare on the dynamics of the tumor-immune interaction with optimal control strategy
...Show More Authors

Contracting cancer typically induces a state of terror among the individuals who are affected. Exploring how chemotherapy and anxiety work together to affect the speed at which cancer cells multiply and the immune system’s response model is necessary to come up with ways to stop the spread of cancer. This paper proposes a mathematical model to investigate the impact of psychological scare and chemotherapy on the interaction of cancer and immunity. The proposed model is accurately described. The focus of the model’s dynamic analysis is to identify the potential equilibrium locations. According to the analysis, it is possible to establish three equilibrium positions. The stability analysis reveals that all equilibrium points consi

The effect of large-scale engineered roughness elements on the hydraulics of the Shatt al-Arab estuary: Methodology
...Show More Authors
Abstract<p>Erosion and deposition are natural phenomena in the river estuaries that could be presented as a dynamic process involving removing materials from one location and accumulating these materials at other locations. These two phenomena may cause changes in waterways and affect offshore structures. The Shatt Al-Arab River Estuary, Iraq was greatly affected by these two phenomena, and topography changes occurred. Velocity profiles and bed shear stress can be used as indicators to identify the erosion and deposition locations. Large-scale roughness elements proved to make beneficial changes in the hydraulic properties of open channels. They can create desirable effects to control erosion</p> ... Show More
