Mosquitoes like Culex quinquefasciatus are the primary vector that transmits many causes of diseases such as filariasis, Japanese encephalitis, and West Nile virus, in many countries around the world. The development in the scientific fields, such as nanotechnology, leads to use this technique in control programs of insects including mosquitoes through the use of green synthesis of nanoemulsions based on plant products such as castor oil. Castor oil nanoemulsion was formulated in various ratios comprising of castor oil, ethanol, tween 80, and deionized water by ultrasonication. Thermodynamic assay improved that the formula of (10 ml) of castor oil, ethanol (5ml), tween 80 (14 ml) and deionized water (71ml) was more stable than other formulas. The formulated castor oil nanoemulsion was characterized by transmitting electron microscopy and dynamic light scattering. Nanoemulsion droplets were spherical in shape and found to have a Z-average diameter of 93 nm. A concentration of castor oil nanoemulsion (250, 350, 450, and 550 ppm) was tested as larvicidal agents and bulk emulsion (1000, 1500, 2000, and 2500 ppm) was tested also and compared against the fourth instar larvae. Our nanoemulsion showed higher activity when compared to bulk emulsion. LC50 for castor oil nanoemulsion and castor bulk emulsion were found to be 268.21 and 409.37ppm after 72 h, respectively. The biochemical assays were carried out to examine the effect of castor oil nanoemulsion on biochemical characteristics of larvae. The treated larval homogenate showed inhibition in the activity of acetylcholinesterase.
The research aims to identify the level of psychological pollution in Iraqi society and the significant differences in psychological pollution in the Iraqi society according to variables. A sample of (600) individuals randomly selected from all governorates of Iraq, with (285) males and (315) females was used in the current study. The researcher adopted the scale of (Muhammad, 2004) psychological pollution consisting of (118) items, which limited (46) items after modification distributed into four areas: denial and abuse of the civilized identity, attachment to foreign formal aspects, effeminacy, and anarchism. The results of the research showed that there is no statistical significance among the individuals of the research sample. They

ان التعايش السلمي والوحدة الوطنية تربطهما علاقة وثيقة تعبر عن حاجة اجتماعية في أطار تطور مجتمعي للدولة العراقية، فقد شهد العراق بعد العام 2003 تحديا جديدا تمثل في تغليب الانتماءات الفرعية والطائفية والعرقية والدينية والمذهبية على الانتماء الوطني مما يؤدي الى بلورة وترسيخ عوامل الانقسام وتفتيت لمقومات الوحدة الاندماج الوطني ، لذلك تعد دعامة التعايش السلمي في المجتمعات ضرورة لازمة من اجل الحفاظ على كينونة

This research paper sheds light on the stages of Atmospheric forecast in Iraq. It was found that atmospheric forecast in Iraq has passed through several successive and interrelated historical stages. Each stage is characterized by special methods of prediction that are different from other stages. The oldest stages used astronomy to forecasting cases of cold , heat, flood and drought

يعد كتاب(الفهرست) لإبن النديم أول كتاب جامع في القرن الرابع الهجري ،حصر الكتب و المؤلفات العربية و رصدها في مجالات العلم و المعرفة و الثقافة و الفن ،و اللغة والأدب و الشعر بما يكشف عن النشاط الفكري ، و الحياة العقلية و العلمية للعصر .
تعد اللغة العربية العامة من المواد التي تدرسها الطالبات في الصف الأول في كل أقسام كلية التربية للبنات، وقد لاحظ الباحث إن الطالبات يفتقرن الى التعرف الى معاني كثير من الكلمات التي ترد في المقطوعات الأدبية الشعرية منها والنثرية التي يقدمها أستاذ المادة، وبما إن وقت المحاضرة محدود فأنه لا يسمح بالتعرف الى أفكار الطالبات حول معاني هذه الكلمات وقد يضطر الأستاذ أخيرا الى تقديم المعاني جاهزة للطالبات من اجل
