Some biological aspects of the zebra mussel, Dreissena polymorpha have been studied at Al-Musayab thermal power plant ,sixty km. south west of Baghdad. Data collected during the period extended from November, 2002 to October, 2003 except for the month of April The population consisted of five age groups; O, I, II, III, and IV which have 0, 1, 2, 3 and 4 annuli respectively. The study also proved the validity of annuli readings for age and growth determination. The average annual growth rates for age groups O,I, II, III, and IV were 5.7, 5.5, 5.4, 5.2 and 5.4 respectively. Average calculated length for laboratory reared mussel was 2.5 mm compared to 5.4 mm in natural environment. Correlation coefficients were very high between age an

: Summary The establishment of the modern Iraqi state necessitated the establishment of diplomatic relations with neighboring countries. However, during the British Mandate period, these relations remained under the management of the British Embassy, which assumed responsibility for Iraq's foreign affairs. As the political situation evolved, the Iraqi Ministry of Foreign Affairs began making strenuous efforts to build a competent and effective diplomatic apparatus. Iraqi diplomatic representatives played an active role in strengthening and developing Iraq's foreign relations by implementing the Ministry of Foreign Affairs' directives, which focused on monitoring political, economic, and social developments in neighboring countries.

In developing countries, conventional physico-chemical methods are commonly used for removing contaminants. These methods are not efficient and very costly. However, new in site strategy with high treatment efficiency and low operation cost named constructed wetland (CW) has been set. In this study, Phragmites australis was used with free surface batch system to estimate its ability to remediate total
petroleum hydrocarbons (TPH) and chemical oxygen demand (COD) from Al-Daura refinery wastewater. The system operated in semi-batch, thus, new wastewater was weekly added to the plant for 42 days. The results showed high removal percentages (98%) of TPH and (62.3%) for COD. Additionally, Phragmites australis biomass increased significant

التخطيط هو احد العناصر الأساسية في الإدارة، وهو عملية مستمرة لا تتوقف في مجال أي عمل اداري ناجح ويعتبر التخطيط الوظيفة الإدارية الأولى وله الأولوية على الوظائف الإدارية الأخرى من تنظيم وتوجيه ورقابة لان هذه الوظائف يجب ان تعكس هذا التخطيط، فالمدير ينظم ويوجه ويراقب لكي يضمن تحقيق الأهداف طبقا للخطط الموضوعة. وكلمة التخطيط من الكلمات ذات المعنى الواسع هنالك البعض يعتبر التخطيط اصلاحا شاملا له منفعته المؤكد

تعتبر الإدارة فيقولون علم التنظيم، ولعل في ذلك إطلاقا لاسم الجزء على الكل إظهار لأهمية هذا الجزء وتزداد أهمية التنظيم وتبدو أكثر جلاء كلما تضخم حجم أعمال الإدارة وبالتالي اتسع إطار الجهاز الإداري الذي يتولى هذه الأعمال. التنظيم والإدارة عنصران متكاملان وإن كان بينهما اختلاف فالتنظيم يعنى تحديد الوظائف وتوزيعها في علاقات إنتاجية معينة وهو يهدف إلى توفير نوع من المهارات والمسئوليات عن طريق التوزيع المناسب ل

The research problem is that the traditional methods of internal auditing are somewhat heavy with long and rigid procedures for the members of the audit process team, especially in light of the current developments that are reflected in the business environment and internal audit reports, so it is necessary to reconsider the traditional internal audit work method and assess the extent of its development by agile methods to reduce the time of the audit process on the activities and elements that add value and direct the effort and time to the activities and elements that add value to the work of the economic unit and the report of the internal auditor.

The research aims to study the possibility of applying agile internal auditing

An experiment was conducted in the plastic house of the Botanical Garden in the Department of Biology, College of Education for Pure Sciences (Ibn Al-Haitham), University of Baghdad during one growth season. The experiment included the study of the effect of three concentrations of citric acid (0, 75, 150) mg. L-1 and four concentrations of malic acid (0, 50, 100, 150) mg. L-1 and their interaction in some of the growth and yield parameters of the broad bean plant, plant height, dry weight, number of leaves, total chlorophyll content, the number of flowers and pods and the weight of the pod. The experiment was carried out in full random design (4× 3) and with three duplicates, the results showed a significant effect of citric and malic aci
