TORCH infections caused by <em>Toxoplasma gondii</em>, rubella virus, cytomegalovirus and herpes simplex virus, and these organisms can transmit from mother to fetus through the placenta. The study aimed to investigate TORCH infection in pregnant women.</p> <p><strong>Materials and Methods: </strong>A cross-sectional and analytical study was conducted on 268 pregnant women (21-45 years) with miscarriage history. Blood samples were taken from all participants for screening TORCH infection. The screening was performed via Cobas e411 and using ROCH test kits manufactured by ROCH Company, Germany.</p> <p><strong>Results: </strong><em>Toxoplasma gondii</em> was found in the highest percentage of TORCH infection (45.1%), followed by Cytomegalovirus CMV (21.6%), then Rubella (18.3%), which was found in the lowest percentage of infection. Non-significant differences were observed among age groups concerning Toxoplasmosis and Rubellosis, but significant differences were observed with CMV infection. Toxoplasma infections were observed with a high rate of infection (61.2%) in house wife, but there were no significant differences in Rubella and CMV infection based on occupation. The highest rate of toxoplasmosis (63.6%) was recorded in the first trimester of gestational age, with a significant difference, whereas there were no significant differences between gestational age with Rubella and CMV infections. Correlation was recorded between toxoplasmosis and the number of miscarriages with the highest rate (68.9%) in the number of miscarriages, whereas a non-significant correlation was recorded between Rubella or CMV infection and the number of miscarriages.</p> <p><strong>Conclusions</strong><strong>:</strong> In TORCH infection, Toxoplasmosis are observed in high rate (45.1%) among pregnant women suffered from previous miscarriages, and significant correlation between toxoplasmosis and the number of miscarriages was found but this correlation was non-significant with Rubella and CMV infection.&nbsp;</p> Safin Tahsin Kakayi Hangaw Omer Haji Ahmed Akil Khudhair Al-Daoody Copyright (c) 2021 http://creativecommons.org/licenses/by/4.0 2021-07-01 2021-07-01 29 2 1 15 Internal Control and Auditing and their Role in Improving the Quality of Financial Reports from The Viewpoint of the Auditors in the General Directorate of Education in the Holy Karbala Governorate https://www.journalofbabylon.com/index.php/JUBPAS/article/view/3637 <p><strong>The aim of this research is to study and monitor the effectiveness of human resources in the holy province of Karbala, analyzing the research based on the descriptive analytical method, in identifying and addressing the research variables.

Proper detection of the disease-causing bacterial agent is required for proper treatment of patients affected with these disorders.</p> <p>Bacteria are classified into two groups: Gram Positive Bacteria and Gram Negative Bacteria. Both types of bacteria have a variety of inherited biochemical traits that allow us to distinguish them, check for their presence and absence, and determine whether they are gram negative or gram positive. As a result, the current review focuses on describing many biochemical assays in a single piece.</p> <p><strong><u>Conclusion</u></strong></p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Gram positive bacteria are identified using biochemical tests such as the catalase test, coagulase test, starch hydrolysis test, and nitrate test, while Gram negative bacteria are identified using biochemical tests such as the oxidase test, urease test, indole test, sulfur test, and methyl red /voges-proskauer test. The analytical profile index test 20E was created to distinguish between Gram-negative Enterbacteriacea and non-Enterbactriacea bacteria. Gram-positive microbes such as Staphylococcus species, Micrococcus species, and other related organisms have also been generated using the API method.</p> Ban Mahmood Shaker AL-Joda Aziz H.

The natural radioactivity of the soil samples has been studied using High Pure Germanium (HPGe) detection system. The activity concentration (A<sub>s</sub>) of the natural series; <sup>238</sup>U, <sup>232</sup>Th and <sup>40</sup>K was determined for the samples. The values of A<sub>s</sub> were ranged (45.641 ± 3.252 - 92.862 ± 4.295), (61.287±2.996 - 135.773 ± 18.366) and (227.9 ± 4.874 - 413.0±7.060) Bq k<sub>g</sub><sup>−1</sup>, respectively. The radium equivalent activity (????<sub>(</sub><sub>????????</sub><sub>)</sub>) was determined with range (52.006 – 130.518) Bq kg<sup>-1</sup>. The total absorbed dose rate (????) calculated from the activity concentration of <sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K in the studied area ranges from 25.53 nGy h<sup>-1</sup> to 58.921 nGy h<sup>-1</sup>. The calculated values of total annual effective dose&nbsp; (????<sub>????????????</sub>) for the soil samples of the study area ranged from 0.156 to 0.361. Since these values are less than unity, the EC report (European Commission, radiation protection report) concludes that the soil from these areas is healthy and poses no substantial radiological risk to the population.</p> Kamal O.

The aim of this paper is to show an iterative procedure that can be utilized to solve such problems. Questions of how to select the (best, worst) value for the objective functions, the nonlinear problem is changed into a linear programming problem (LPP), with two or more constraints and more than one varieties by two algorithms (1) subtracting the interval of numerator of the fractional from the interval of denominator and (2) the denominator to be one of the constraints. Finally, after we solve each objective function without intervals individually by modified simplex method, we use a new technique via transforming it to single-objective function with the same constraints. Numerical examples are illustrated to show the efficiency of these algorithms and new technique.</p> Ronak M. Abdullah Sazgar M.

The analysts and economic researchers call the third millennium water era instead of the era of oil that characterized the previous years. The research concluded that, in economic terms, water is expected to become a commodity sold and bought as any economic commodity Water security should be studied from the point of view of the water problem. The first one is related to climate variables, the other to the mismanagement and planning of water resources and third regional because the water sources originate from outside the Iraqi borders. Finally, the research recommends the need to move away from linking water with political positions and politics because politics is a changing world.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> Amina Abdul-Elah Hamdoon Copyright (c) 2021 http://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 29 2 210 224 Effect of COVID-19 Pandemic upon People's Life Aspects: An Overview Study https://www.journalofbabylon.com/index.php/JUBPAS/article/view/3771 <p>Coronaviruses are a broad strain that includes a group of viruses which may cause a respiratory diseases ranging in severity from common colds to more severe diseases that lead to death. Recently in China, the emerging disease Covid-19 was discovered, which causes a range of symptoms such as fever, dry cough, fatigue, aches and pains, headaches, nasal congestion and loss of taste or smell. The new Corona disease (COVID-19) has forced the entire world to face one of the most difficult challenges in contemporary history, as this virus has infected millions and killed hundreds of thousands of people in various age groups.

Iris identification was one of the most sophisticated biometrical techniques for effective and confident authentication. Current iris identification system offers accurate and reliable results based on near- infra -red light (NIR) images when images are taken in a restricted area with fixed-distance user cooperation. However, for the color eye images obtained under visible wavelength (VW) without cooperation between the users, the efficiency of iris recognition degrades because of noise such as eye&nbsp;blurring&nbsp;images, eye lashing, occlusion and reflection. This works aims to use Speeded up robust features Descriptor (SURF) to retrieve the iris's characteristics in both NIR iris images and visible spectrum. This approach is used and evaluated on the CASIA v1and IITD v1 databases as NIR iris image and UBIRIS v1 as color image. The evaluation results showed a high accuracy rate 98.1 % on CASIA v1, 98.2 on IITD v1 and 83% on UBIRIS v1 evaluated by comparing to the other methods</p> Mohammed A. Taha Hanaa M.
