Research summary
تتناول هذه الدراسة التراكم الحيوي للمعادن الثقيلة، الكادميوم والرصاص، في الدودة الشريطية Postgangesia inarmata وبعض أنسجة أسماك الجري Silurus glanis في محافظة نينوى، شمال العراق. تم جمع عينات الأسماك من منطقة سد الموصل وتحليل تراكيز المعادن باستخدام جهاز طيف الامتصاص الذري. أظهرت النتائج وجود فروقات معنوية في تراكم الكادميوم والرصاص بين الأسماك المصابة وغير المصابة بالديدان الشريطية في الكبد، الكلى، الأمعاء، الخياشيم، والعضلات. بلغت تراكيز الكادميوم والرصاص في الدودة الشريطية 24.24 و787.87 ميكروغرام/غرام على التوالي. تشير الدراسة إلى أن الأسماك والطفيليات الداخلية يمكن استخدامها كمؤشرات حيوية لتلوث المعادن الثقيلة في النظم البيئية المائية.
Critical review
تعتبر هذه الدراسة خطوة هامة في فهم تأثير التلوث بالمعادن الثقيلة على النظم البيئية المائية، ولكنها تفتقر إلى بعض الجوانب التي يمكن تحسينها. على سبيل المثال، لم تتناول الدراسة تأثيرات التلوث على الصحة العامة للبشر الذين يستهلكون هذه الأسماك. كما أن الدراسة لم تشمل أنواعًا أخرى من الأسماك أو الطفيليات التي قد تكون موجودة في نفس البيئة، مما قد يحد من تعميم النتائج. بالإضافة إلى ذلك، كان من الممكن توسيع نطاق الدراسة لتشمل تأثيرات موسمية أو جغرافية مختلفة على تراكم المعادن. بشكل عام، توفر الدراسة بيانات قيمة ولكنها تحتاج إلى مزيد من التوسع والتفصيل لتقديم صورة شاملة.

Data on ١٦٠١ records over five years were used to study the reproductive and productive performance of Awassi ewes kept at the animal husbandry station (Darnajookh) in Iraq. The overall means were ٨٠,٦٩±١,١٪, ١,٠٧٧±٠,٠٠٨, ٩٢,٨٢±٠,٨٣٪, ٠,٨٠٥±٠,٠١٤ , ١٨,٩٨±٠,٣٥ kg, ٥٣,٣٨±٠,٣٢ kg and ٢٢,٥١±٠,١٨ kg for fertility, litter size, pre-weaning survival rate, number of lambs weaned per ewe exposed to the rams, ewe productivity ( total weight of lambs weaned per ewe exposed to the rams), body weight of ewe at breeding and weaning weight of lambs, respectively.
Corruption is a wide phenomenon of proliferation and behavior contrary to all laws and regulations, and contradicts the values and principles of Islamic law, and is a form of State collapse and the loss of current and future generations rights as he represents one of the obstacles to economic development in general and education, in particular through its impact on key indicators of education in Iraq through a direct impact on these indicators and the impact of this phenomenon of a negative impact led to the disparity of income between the different segments of society and the spread of the phenomenon of illiteracy in the education and poor knowledge of the rate in reading and writing and the collapse of the health sector, which calls for control and concerted one-state institutions efforts and the need for cooperation among States to reduce them, and continuity is linked to the desire of man to get a physical or moral gains illegally and be clear heavily in developing, particularly in government institutions, communities, and that this phenomenon multiple types and manifestations of the outcome several reasons, including economic, political, social, and may be internal or external, leaving profound effects on the economies of the countries, particularly developing countries, the study was based on the premise that financial corruption traces negative on the process of education and the fight against financial corruption process through the activation of the role of the relevant regulatory institutions and develop laws strictly limiting its spread for the advancement of education and make it better and showed the importance of the study of financial corruption task and contemporary with an economic and social impact of the issue is Ba_i_ra phenomenon of financial corruption in Iraq and its impact on disability and education process and the resulting damage and loss of confidence in the state and lack of respect for laws.
Clay mineralogy of the Miocene successions taken from northern Iraq constitute an important paleoenvironmental indication for the evolution of these sediments. Palygorskite is a common mineral especially in the lower Miocene sediments of Euphrates formation and the upper detrital part of the Fat'ha Formation belonging to the middle Miocene. Scanning Electron Microscope (SEM) study indicated that this mineral, was formed authigenically by neoformation in suitable chemical conditions within the evaporitic environments. Other minerals (kaoloinite and illite) have been most probable formed in detrital system and were preserved in those evaporitic conditions. Common kaolinites in the Injana clastic Formation (Upper Miocene) as well as its habit in SEM images are indicators for its detrital origin in such continental sediments.
The study was conducted in a fish laboratory in the college of veterinary medicine during the period between the months of March and September. The experiments of this study were performed in laboratory conditions. Five dosage levels of Ivermectin were administered.
The paper includes in the first stage an estimate of the runoff volume and sediment load, resulting from rainfall on a watershed of Alkhoser seasonal river, north-eastern Mosul city/Republic of Iraq, which has an area of up to 725 km2. There is a p roposal for construction of a rainwater harvesting dam for the supplementary irrigation in the region which is exploited by planting wheat and barley crop widely. Digital elevation model (DEM) was adopted in order to describe the topography of the region, which is one of the main factors affecting the water flow direction and velocity. It also adopted the daily data of rainfall, maximum and minimum temperature, for the period 1989 to 2007 for Mosul to estimate the volume of runoff and sediments resulting from each effective rainstorm. The applied model includes the Geographical Information System (GIS).
