لقد اخذ موضوع المياه حيزا كبيرا في كتابات الباحثين وصناع القرار على المستوى العالمي والعربي والمحلي لاسيما في المناطق الجافة وشبه الجافة لاسباب كثيرة منها ما هو متعلق بندرة هذا المورد، والذي يقابله زيادة في الطلب مع تزايد اعداد السكان وارتفاع مستوى معيشتهم اذ تزداد الحاجة اكثر للمياه فضلا عن استخدامها في مجالات الزراعة والصناعة والاحتياجات المنزلية مما يجعلها عنصرا ضروريا وحيويا في حياة المجتمعات، كما وتعد الموارد المائية لاسيما التي تشترك فيها اكثر من دولة مصدرا من مصادر النزاع والتوتر بين الدول وستشكل حلبة الصراع المستقبلي تحت مسمى (حرب المياه) فهنالك العديد من الدراسات العالمية التي اهتمت بالادارة الاستراتيجية للموارد المائية واخذت كل دراسة جانبا معينا بحسب الاولوية التي يراها الباحثون في تشخيص المشكلة مما يؤكد ازمة المياه على المستوى العالمي. لقد تباينت آراء الباحثين في عرض استراتيجيات ادارة الموارد المائية فمنهم من اعطى الاولوية لاصحاب المصلحة في حل المشكلة والبعض الآخر ركز على التحليل البيئي وآخرون بينوا اهمية الادارة الداخلية الصارمة وغيرهم وجدوا ان المحور القانوني والسياسي هو الاهم في الاستراتيجيات لاسيما في الموارد المائية التي تشترك فيها اكثر من دولة وذهب البعض الى ان المحاسبة المائية وبصمة المياه كفيلة في السيطرة على ادارة الموارد المائية وعدوها محورا مهما في الادارة المتكاملة للموارد المائية. وفي العراق فان مشكلة المياه مركبة تتكون من مجمل المحاور السابقة وهذا يتطلب صياغة استراتيجية مبنية على تحليل دقيق لهذه العوامل للخروج بخيار استراتيجي يتناسب وحجم هذه التحديات لمعالجة هذه الازمة الخطيرة وبالتالي فان اختيارنا للدراسات العالمية والعربية والمحلية المشابهة لحالة العراق سيسهم في توضيح الاستراتيجية المقترحة اختصارا للجهد والوقت وذلك من خلال تحليل الاستراتيجيات مدار البحث للاستفادة منها في رسم ملامح الاستراتيجية العراقية.
Aphid Aphis spp (Hemiptera:Aphididae) and Thrips Thrips spp (Thysanoptera: Thripidae) an economically important pests on several crops in the world and Iraq, that transfer many viruses diseases to it. Field studies were conducted to assessment the population density of these insects and susceptibility of six varieties (Barin, Revera, Divela, Rudlph, Alazata and Pleny) to infestation during 2013 spring season. The results were showed that all Potato varieties were infested by Aphis and Thrips on spring plantation but with different percentage. The Divela variety was higher percentage of infestation and high population density of aphid which averaged 1.47 insect/ leaf while in Alazata was the lower population density which averaged 1.02 in
... Show MoreThe research was carried out in lathhouse on one-year-old apple seedlings of the Ibrahimi variety in the Karma-Fallujah region for the 2021 growing season to study the effect of methods of adding nano-fertilizer and humic acid on seedling growth. A two-factor experiment was designed according to a randomized complete block design, with three replicates and two seedlings per experimental unit, so the number of seedlings was 54. The first factor includes NPK nanofertilizer at three levels (0- and 2-ml L-1 foliar spray and 5 ml L-1 soil application). The second factor is humic acid at three levels (0 and 5 g of seedlings - 1 foliar spray and 10 g of seedlings - 1 soil application). The results of the study show that the NPK nano-fertil

Where the (MLE) will lose its advantages because of the bad influence caused by the Outliers. In order to address this problem, new statistical methods have been developed so as not to be affected by the outliers. These methods have robustness or resistance. Therefore, maximum trimmed likelihood: (MTL) is a good alternative to achieve more results. Acceptability and analogies, but weights can be used to increase the efficiency of the resulting capacities and to increase the strength of the estimate using the maximum weighted trimmed likelihood (MWTL). In order to perform t

Show MoreThe job that confronts players with the effectiveness of shooting with an air rifle is high, so it requires necessary functional adaptations that differ in their degrees from other sports. Regular training in air rifle shooting leads to physiological changes in most of the body's internal systems, and changes and responses can be identified. The functional accompanying physical activity through the presence of body components that reflect these physiological changes in the form of changes in some components, and the importance of research lies in studying the physiological changes accompanying the maximum physical effort and the consequent development of the level of achievement in the effectiveness of shooting with air rifle and body

The researchers concluded the study by interpreting and discussing the results that the most important variables must be relied upon when training and selecting runners that got the best saturation on their factors: 1-The first factor which refers to the total distance of the plan to pass the third barrier + the total distance of the plan to pass the ninth barrier + the total distance Plan to cross the sixth barrier. 2-The second factor which refers to the total vertical speed before passing the third barrier + the total vertical speed before the sixth barrier + the total vertica

Sixteen sites of sediment were selected and distributed along Shatt Al-Arab River and the Iraqi marine environment. The samples were distributed among one station on Euphrates River before its confluence with Tigris River and Shatt Al-Arab formation, seven stations along Shatt Al-Arab River and eight stations were selected from the Iraqi marine region. All samples were collected from surface sediment in low tide time. ICP technique was used for the determination of mercury and arsenic for all samples, while cadmium and lead were measured for the same samples by using Atomic Absorption Spectrosc
