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.
The study highlights the critical need to focus on the physical, motor, and technical abilities of female fencing players by developing and testing modern, scientifically-based training methodologies tailored to the specific demands of the sport. The study's objective was to assess the effectiveness of targeted three-dimensional training in enhancing the participants' motor skills and technical performance. Utilizing an experimental design, the study involved forming both experimental and control groups. The sample comprised 16 female fencers from the College of Physical Education and Sports Sciences for Girls. After excluding two players during the exploratory phase, the remaining 14 were evenly divided into experimental and contro

The aim of this study was to evaluate the effect of zirconium nanoparticles into acrylic-based heat cured soft denture lining material against Candida albicans, and the amount of zirconium ion release of soft liner/ZrNPs composite. Furthermore, evaluate shear bond strength after ZrNPs addition to soft liner. Materials and methods: Zirconium nanoparticles were added into acrylic-based soft denture liner in various percentages (1%, and 1.5% by weight). Two hundred and fifty specimens were arranged and isolated into four groups as per the test to be done The antifu

Show MoreWith the aim of developing potential antimicrobials, a series of novel Ciprofloxacin methylene isatin derivatives incorporating different aromatic aldehydes were synthesized and characterized by FTIR, 1H NMR, Mass spectroscopy and bases of elemental analysis. In addition, the in vitro antibacterial and antifungal properties were tested against some human pathogenic microorganisms by employing the disc diffusion technique. A majority of compounds were showing activity against several of the microorganisms. The relationship between the functional group variation and the biological activity of the evaluated compounds is discussed. From comparisons of the compounds, 3c was determined to be the most active compound.
Abstract Background: The daily usage of maxillofacial prostheses causes them to mechanically deteriorate with time. This study was aimed to evaluate the reinforcement of VST50F maxillofacial silicone by using yttrium oxide (Y2O3) nanoparticles (NPs) to resist aging and mechanical deterioration. Materials and Method: Y2O3 NPs (30–45nm) were loaded into VST50F maxillofacial silicone in two weight percentages (1 and 1.5 wt%), which were predetermined in a pilot study as the best rates for improving tear strength with minimum increase in hardness values. A total of 120 specimens were prepared and divided into the control and experimental groups (with 1 and 1.5 wt% Y2O3 addition). Each group included 40 specimens, 10 specimens for each paramet

This diversity in properties is due to the possibility of modification on the composition of this Nano compound, where the Graphene oxide is capable of more modification via addition other functional groups on its surface or at the edges of the sheet. The reason for this modification possibility is that the Sp3 hybridization (tetrahedral structure) of the carbon atoms in graphene oxide, and it contains many oxygenic functional groups that are able to reac with other groups. In this research the effect of addition of some amine compounds on electrical properties of graphene oxide has been studied by the

The selection of a method was dependent upon the purpose, e.g., quantification or identification of pigments. The introductory part of this review focuses on describing the importance of setting up a pigment-associated safety profile. The formation of different degradation chemical substances as well as impurity trends can be indicated through the chemical investigation of pigments in tattoo products. It is noteworthy that pigment recognition in tattoo inks can work as a preliminary method to identify the pigments in a patient's tattoo before being removed by laser therapy. Contrary to the stud
The importance of the research is evident in the use of exercises with the training device, which is one of the modern techniques in teaching the abilities of players, especially in teaching the skill of the backhand, and in improving the accuracy of the performance of players and increasing the contribution to the formation of a base for the game for players who have a good level of learning and upgrading the game to reach a certain achievement, and the research issue was represented in the lack of accuracy in sending balls to the required areas to achieve points, especially in the performance of the skill of the backhand due to the speed of play during the course of the match, and the study aimed to introduce modern technology usi
