تعتبر المدرسة المتوسطة هي القاعدة التعليمية الثانية بعد المدرسة الابتدائية والتي تقوم عليها أنظمة التعليم المتنوعة فهي تمثل اللبنة الثانية في الصرح التعليمي لأنها مرحلة مهمة تستقبلها الطلبة في العمر الحرج المليء بالتطورات الجديدة على المستويات الثلاثة البايلوجي والنفسي والاجتماعي وعليه يأتي هنا دور القيادة التربوية للقيام بواجباتهم الإدارية والقيادية في قمة الهرم الإداري للمدرسة المتوسطة والتي تستوجب بلا شك امتلاكهم القدرات والمهارات اللازمة لقيادة العمل التربوي.
لذا يعد مدير المدرسة المتوسطة قائد تربوي له الدور المهم والفاعل في نجاح العملية التربوية في المدرسة التي يتولى أدارتها ويفترض أن تكون لديه الخبرة والمؤهلات اللازمة ولولا التنظيمي والالتزام من خلال قيادة مدرسة ناجحة تعمل على إرساء علاقات إيجابية مع المدرسين ويثر حوافزهم لعمل ويرى الباحث أن مديري المدارس المتوسطة لا يسيروا في قيادة مدارسهم وتعاملهم مع المدرسين والطلبة وأفراد المجتمع المحلي الذي لهم اتصالات أو علاقات مختلفة مع المدرسة على نمط واحد في القيادة ولا يكون لديهم برامج يطبق في المدرسة أو تنفيذ في تعاملهم الشخصي واجراتهم ووسائلهم الإدارية باختلاف حلقاتهم الإدارية من جهة واختلاف أعدادهم وتدريبهم واتساع خبرتهم ونظرتهم إلى الإدارة من جهة أخرى، ونظراً لهذا الاختلاف فأننا لا نستطيع أيجاد نمط واحد من أنماط الإدارة أو أسلوب متماثل في سلوك أداري لمدير المدارس المتوسطة كافة، ومع ذلك فان الفاحص أو المدقق لما يجري من هذه المدارس على اختلاف أنواعها ومستوياتها من أعمال أدارية وتصرفات شخصية نستطيع أن نلمس النمط القيادي المتبع من قبل مدير تلك المدارس، أن النمط القيادية الذي يطبق به مدير المدرسة المتوسطة من الممكن أن ينعكس على درجة رضا المدير عن عمله، كما أنه قد ينعكس على سلوكه وإخلاصه وثقافته في صدق أهدافه.
وفي ضوء ما تقدم فان ما يمارسه مديرو المدارس من أنما قيادية وعلاقتها برضا العاملين في المدارس المتوسطة من أعضاء الهيئات التدريسية أو المشرفين الإداريين على وجه التحديد ومدى تأثير هذه الأنماط على مناخ العلاقات الشخصية والإنسانية في هذه المدارس يثير كثير من التساؤلات حول ما يدور داخل هذه المؤسسات التربوية التعليمية والتي يحسها الباحث خلال عمله في الوسط التعليمي وفي هذه المرحلة الدراسية ومعايشته ولقاءاته مع العديد من المشرفين الإداريين وأعضاء الهيئات التدريسية لهذا رأى الباحث ضرورة دراسة هذا الموضوع للتعرف على أنماط القيادات التربوية والإدارية لكتابة عنوان البحث.
This study focused on the role and importance of alkaloid compounds in Punica granatum peels which is one of many wide distribution medicinal fruits. Two kinds of pathogenic fungi were isolated from patients in Baghdad to be tested, also a type of extracts was prepared, alkaloids were isolated and partially purified and detected by two ways, a classic depended technique also used for determine these alkaloids, results showed an observed differences among extracts or treatments towards the fungi samples. So this study was one of the scientific applications to find natural alternative compounds that inhibit the growth of several pathogenic organisms that cause dangers and harms for human health.
Concentrations of heavy metals (Copper Cu, Iron Fe, Manganese Mn, Cadmium Cd, and Lead Pb) have been studied in river crab Sesarma boulengeri (Outer part of the shield and interior tissues) which caught from two stations in Shatt Al – Arab river (Salhia and Aldeir areas). Elements concentrations were measured by Flame Atomic Absorption Spectrophotometer, concentration of heavy metals in the internal tissues was higher than in the outer shield in both of the stations with the highest value of the elements was to iron 95.21 mg\ kg during the spring as well as copper was 55 mg\kg and manganese was 39.09 mg\kg. The study showed the presence of seasonal changes in the studied heavy metals concentrations values in the tissues of river crab;

For the period 14/ 5/ 2016 to 4/ 6/ 2016 in order to study the effect of adding Curcuma longa - to the diet of quails - on some productive and physiological characteristics of the Japanese quail birds bred for meat production. Using (48) quail birds which are two weeks old provided by Department of Agricultural Research. The birds were divided randomly after weighing them into three treatments; four replicate treatments for (4 bird/ replicate). The treatments as follows: (T1) control group (fed diet without any supplement), second (T2) and third (T3) groups were fed diet supplemental 4.5 and 9g Curcuma powder /

Show MoreThe aim of this study was to increasing natural carotenoides production by a locally isolate Rodotorula mucilagenosa M. by determination of the optimal conditions for growth and production of this agents, for encouragest to use it in food application permute artificial pigments which harmfull for consumer health and envieronmental. The optimal condition of carotenoides production from Rhodotorula mucilaginosa M were studied. The results shows the best carbon and nitrogen source were glucose and yeast extract. The carotenoids a mount production was 47430 microgram ̸ litter and 47460 microgram ̸ litter, respectively, and the optimum temperature was 30°C, PH 6, that the carotenoides a mount was 47470 microgram ̸ litter and 47670 microgr

The effect of adding raw bacteriocin produced by Lactobacillus bulgaricus to cheese curd at an amount of (5 and 10 and 15) mL/kg cheese as a biological preservative to prolong the shelf life of soft cheese, in addition to the control treatment, knowing that each 1 mL of bacteriocin filter contains 15 units/ mL of bacteriocin. The results of the physicochemical, microbial and sensory tests for cheese stored at refrigerator temperature for a period (zero) to (21) d of adding bacteriocin showed the superiority of the treatment of cheese added to 15 mL/kg cheese of bacteriocin over the rest of the other treatments during the storage period, wh

ABSTRACT The role of specific amino acids namely cysteine, methionine, threonine and asparagine in the protection provided by vamin solution against B-lactam inhibition to E. coli was evaluated in vitro. In minimal medium, Cells were treated with 32 ug/ml of penicillin G, carbencillin, hostacillin, cloxacillin and cephalotin in the presence of specific amino acid supplementations. Deletion of specific amino acids from the media abolished the protection provided by vamin. Threonine was essential for the protection of cells against all tested antibiotics, while cysteine was essential for protection against carbencillin and cephalotin Deletion of methionine or asparagine abolished the protec- tion against carbencillin and to a less extent ce

... Show MoreIn this research, several estimators concerning the estimation are introduced. These estimators are closely related to the hazard function by using one of the nonparametric methods namely the kernel function for censored data type with varying bandwidth and kernel boundary. Two types of bandwidth are used: local bandwidth and global bandwidth. Moreover, four types of boundary kernel are used namely: Rectangle, Epanechnikov, Biquadratic and Triquadratic and the proposed function was employed with all kernel functions. Two different simulation techniques are also used for two experiments to compare these estimators. In most of the cases, the results have proved that the local bandwidth is the best for all the
