Get PDFأكسيو قدم المفهوم الأتي، يقال للمقاس M بأنه مكمل معمم إذا كان لكل مقاس جزئي N من M، يوجد مقاس جزئي K من M بحيث أن K +N=M وNK Rad(K).نها حمادة والهاشمي قدما المفهوم الأتي، يقال للخاصية S المعرفة على المقاسات بأنها خاصية شبه جذرية أذا تحقق الأتي:1. ليكن N→ M :f تشاكلاً شاملاً. أذا كانت M مقاساً يملك الخاصية S فأن N مقاساً يملك الخاصية S.2. كل مقاس M يحوي على المقاس الجزئي S(M).هذه الملاحظات قادتنا إلى اقتراح تعريف المقاسات المكملة المعممة من النمط S. لتكن S خاصية شبه جذرية، يقال للمقاس M المعرف على الحلقة R بأنه مقاس مكمل معمم من النمط S. إذا كان لكل مقاس جزئي N من M، يوجد مقاس جزئي K من M بحيث أن M=N+K وN∩ K S(K).الغرض الرئيسي من هذا البحث هو تطوير خواص المقاسات المكملة المعممة من النمط S. لقد أعطينا مجموعة من القضايا الجديدة وأوضحنا المفاهيم بأمثلة.Xue introduced the following concept: Let M be an R- module. M is called a generalized supplemented module if for every submodule N of M, there exists a submodule K of M such that M = N +K and N Ç K Í Rad(K).
Hamada and B. AL- Hashimi introduced the following concept:
Let S be a property on modules. S is called a quasi – radical property if the following conditions are satisfied:
For every epimorphism f: M ® N, where M and N are any two R- modules. If the module M has the property S, then the module N has the property S.
Every module M contained the submodule S(M).
These observations lead us to introduce S- generalized supplemented modules. Let S be a quasi- radical property. We say that an R-module M is S- generalized supplemented module if for every submodule N of M, there exists a submodule K of M such that M = N + K and N Ç K Í S(K).
The main purpose of this work is to develop the properties of S-generalized supplemented modules. Many interesting and useful results are obtained about this concept. We illustrate the concepts, by examples

Get PDFتم التحري عن التداخلات السريرية لحالة الحديد في الجسم والتي تشمل (حديد مصل الدم والحديد المخزون في الفيريتين) عند مرضى داء السكري غير المعتمد على الانسولين(النوع 2 ) .
شملت الدراسة 36 انثى ، من الاناث 18 مصابة بداء السكري ( النوع 2) و 18 انثى من الاصحاء .
كانت المجموعتين متقاربتين بالعمر وفي مؤشر كتلة الجسم (BMI ).
اما مجموعة المريضات فقد كانت متماثلة فيما بينها من حيث العمر ومؤشر كتلة الجسم والعلاجات الفموية الخافضة للسكر(مثل الكلبنكلامايد والميتفورمين )ومضاعفات داء السكر.
تم قياس الدوال الكيموحيوية لمجموعتي الاصحاء والمرضى وقد شملت :- الانسولين, الكلوكوز بعد الصيام, الحديد في مصل الدم والفيريتين.
لوحظت زيادة معنوية عالية في جميع هذه الدوال عند المرضى مقارنة بالاصحاء. وقد كانت هذه الزيادة واضحة في مقاومة الانسولين (IR ) والتي تم حسابها حسب المعادلة :-
IR = (الانسولين µIU/ ml × الكلوكوز mmol/ L) / 22.5
حيث وجدت (275.9 ± 22.7 ) مقارنة بالاصحاء (41.5 ± 11.3 )The clinical impact of interaction between body iron status (serum iron and ferritin ) and type 2 diabetes has been investigated in this study . Thirty six females were enrolled, eighteen type 2 diabetes and eighteen apparently healthy. These two groups were matched for age and body mass index BMI. The eighteen diabetes females were matched for age, BMI, pharmacological treatment (oral hypoglycemic agent), and chronic diabetes complications .
The biochemical parameters measured for both groups (control and diabetes patient) were fasting insulin(Io),fasting blood glucose (Go) , serum iron and ferritin .
A significant increase in all parameters in patients compared to healthy control was noticed . The insulin resistance ( IR) which was calculated by the equation:-
IR= (Io µIU/ ml × Go mmol/ L)/22.5 was clearly demonstrated to be significantly higher in female diabetes patient( 275.9 ± 22.7) compared to control (41.5±11.3) .

Variables Affecting Developments of Hydroxyapatite Coating by Using Electrophoretic Deposition Technique
Get PDFElectrophoretic Deposition (EPD) process offers various advantages like the fabrication of the ceramic coatings and bodies with dense packing, good sinterability and homogenous microstructure. The variables namely (applied potential, deposition time and sintering temperature) affected the development of hydroxyapatite (HAP) coatings. The coating weight and thickness were found to increase with the increase in applied potential or coating time. Sintering temperature was found to affect in change phases of the metal, furthermore the firing shrinkage of the HAP coating on a constraining metal substrate leads to serve cracking. XRD Characterization indicates the formation of a contamination free phase pure, and the optical micrographs show the relatively uniform distribution of the HAP coatings. Analysis of the stiochiometric HAP before EPD process and after sintering indicates that the structural aspects do not change i.e. the EPD in ethanol does not affect the structure of HAP powder
Study of Stability of Personal Dosimeter
No full textThe study is carried out by using personal dosimeters (film badge). The films are irradiated to absorbed dose of range (0.01-10000 rad). The calibration curves are drawn by using the ordinary method taking into account the filtration effects in three regions (D (Pb/Sn),D(Du),D(300). The calibration films are stored in ambient condition. It is found that the optical density increases, which is attributed to the photodegradation of the films may induce localized states in the energy gap causing increasing in optical absorption, but optical density decreases, which attributed to the photodegradation of the films may cause some cracks at the film surface during the first month, whereas at the rest months we see clear stability in optical density for the irradiated films. Before irradiation, there is increasing in optical density during the second month, and decreasing in optical density during the rest months. It is concluded that aging effects must be considered for personal dosimeter before and after irradiation to know its use ability as a permanent record
