Abstract

Moderation concerned as the most remarkable characteristics which accompanied Islamic mission from its beginning and this characteristic represented clearly in the first personality in this religion who is prophet Mohammed (p.b.h) and his manner for calling to Islam which stated in Almighty state ( And we made you moderate nation ) , So moderation is the remarkable criteria in this mission and religion , this study was an easy attempt to present the moderation of the prophet in taking this mission with calling for it and his treating with religion followers , then we got clear & clean conclusion to silence all the enemies of this religion and proof the false of their claims to it which its about extremist blames in religion and proof that moderation is the manner which the prophet use to set the basics of this religion and its state .Moderation in language is the moderate between good and bad , the moderate between them is the middle in his ancestors and higher in his rank the Almighty state (And we made you moderate nation ) contained the same previous meanings ,(( Al Zajaaj had two states in it , some state moderate is fairness and others state it’s the best , the two different terms with one meaning because fairness is good and good is fairness , it had been said in the characteristic of the prophet that he was from the moderate of his tribe that is to say the best of them , Al Fadil describe the ancestry that he was from the moderate of his tribe and this truth known for linguistics because Arab use representation a lot , like represent the tribe with valley and bottom and the best of the valley its bottom , and it said this from the middle of his tribe which all means from the best place , so the prophet from the best place for Arab ancestors , therefore his nation been moderate nation which means the best ) and I took in this research with in the study a lot of points like , moderation features in the prophet’s personality , the prophet moderation in taking Islamic mission , Islamic mission stages to express moderation in expanding Islam and other points .

تعد الوسطية من ابرز الصفات التي رافقت الدعوة الاسلامية منذ بدايتها الاولى، وقد تجسدت هذه الصفة بصورة واضحة في الشخصية الاولى في هذا الدين وهو الرسول محمد  فالوسطية هي ابرز صفة في هذه الدعوة وفي هذا الدين، فكانت هذه الدراسة محاولة بسيطة في ابراز وسطية الرسول  في تلقي هذه الدعوة ووسطيته في دعوته الى دين الله وفي تعمله مع اتباع هذا الدين، وبالتالي نخرج بنتيجة واضحة وجلية تخرس كل اعداء هذا الدين وتثبت زيف اتهاماتهم الباطلة تجاهه وهي تهم التطرف، وتثبت ان الوسطية هو المنهج الذي سار عليه الرسول  في ارساء دعائم هذا الدين ودولته. والوسط في اللغة هو التوسط بين الجيد والرديء، الوسيط فيهم أي أوسطهم نسبا وأرفعهم محلا، المعاني السابقة ذاتها، ((قال الزجاج: فيه قولان: قال بعضهم: وسطا عدلا، وقال بعضهم: خيارا واللفظان مختلفان والمعنى واحد؛ لأن العدل خير والخير عدل، وقيل في صفة النبي: إنه كان من أوسط قومه، أي: خيارهم تصف الفاضل النسب بأنه من أوسط قومه وهذا يعرف حقيقته أهل اللغة؛ لأن العرب تستعمل التمثيل كثيرا فتمثل القبيلة بالوادي والقاع وما أشبهه فخير الوادي وسطه فيقال هذا من وسط قومه ومن وسط الوادي وسرر الوادي ومعناه كله من خير مكان فيه وكذلك النبي من خير مكان في نسب العرب وكذلك جعلت أمته أمة وسطا أي خيارا))، وقد تناولت بالبحث ضمن هذه الدراسة العديد من النقاط منها ملامح الوسطية في شخصية الرسول ، ووسطية الرسول في تلقي الدعوة الاسلامية، ومراحل الدعوة الإسلامية تعبير عن الوسطية في نشر الاسلام، وغيرها من النقاط.

Abstract

Background: The aim of this study was to evaluate the bonding effect of different intermediate agents on the bondstrength of silorane resin composite (Filtek™ P90,3M ESPE) that repaired by either silorane (Filtek™ P90) ormethacrylate based resin composite (Filtek™ Z250,3M ESPE)Materials and Methods: Eighty specimens of resin composite prepared by filling silorane (Filtek™ P90) into a retentivecavity (6mm in diameter and 2mm in depth) of acrylic mold. The composite were polymerized, water stored at 37°Cfor one week. Their surface were finished with medium (violet) super-snap disks then rinsed in ultrasonic cleaner.Repair was performed with either silorane (Filtek™ P90) or methacrylate based composite (Filtek™ Z250) by usingseveral intermediate agents which include (P90 System Adhesive, Adper Scotchbond Multipurpose and Clearfilrepair kit).The shear bond strength (crosshead speed 0.5 mm/min) was measured after an additional water storageof 24 hour.Results: Statistical analysis of data revealed that intermediate agents enhanced the bond strength significantly(p<0.001).The highest shear bond strength were determined for Clearfil repair kit and P90 System Adhesive whichwere significantly higher than the control (p<0.001). Adper Scotchbond Multipurpose enhanced the bond strengthsignificantly than the control but it was significantly lower than the other adhesive systems (p<0.001).Conclusions: The Clearfil™ Repair kit and P90 System Adhesive were the most effective intermediate agents for repairof silorane restoration with both silorane and methacrylate repair materials.Use of Adper Scotchbond Multipurposeresulted in bond strength which is considered clinically inadequate

Abstract

This paper presents suggested modified algorithm to draw the geographic maps. Cubic spline interpolation had been used to draw these maps by generating intermediate points between each two points from a set of given points, where these intermediate points represent the control points which they are used to constrain the curvature of cubic spline depending on a value named divisor value that representsthe distance between any two adjacent points at spline knots, and specified by the user. Intermediate points have a great effect on curve shape, through dividing the interval between two adjacent points into equal subintervals. This makes the results of the weights ai, bi and ci in spline function will be equal to zero and di has already been determined to be di = yi , according the equations determining the weights,. So we can draw lines and polygons that are necessary in drawinggeographic maps.

Abstract

Aims: To determine the prevalence of dental caries among intermediate and secondary school students 13–16 years old to determine the age and sex difference and to obtain data that can help in planning preventive dental health programs for school students in Yemen. Materials and Methods: A random sample of 512 intermediate school students,449 secondary school students were examined. Interme-diate school student sample was divided into 3 age groups namely 13,14,15 and secondary school stu-dent sample was divided into 3 age groups namely 16,17,18 years old. The WHO methodology (1997) was used to assess the individual tooth status. Results: The mean DMFT for the total sample was 5.2±0.13; which increased with the increasing of age from 4.54 to 4.84 to 6.47 for the age groups 13,14,15 years old respectively; without significant sex difference as total 5.44 for males and 5.14 for total females. Results of dental caries for the secondary school students showed that the mean DMFT for the total sample was 5.98± 0.14, which decreased with the increasing of age from 5.60 to 6.49 to 5.85 for the age groups 16,17,18 years old respectively, with peak value at 17 years old without signifi-cant sex difference, 5.74 for total males, 6.21 for total females. Conclusion: The mean DMFT for both intermediate, secondary schools increased with increasing age with statistical significant difference with no sex differences.

Abstract

Many attacks may be carried out against communications in Local Area Networks (LANs). However, these attacks can be prevented, or detected, by providing confidentiality, authentication, and data integrity security services to the exchanged data.This paper introduces a security system that protects a LAN from security attacks. On each host in the protected LAN, the security system transparently intercepts each outbound IP (Internet Protocol) packet, and inserts a crypto header between the packet IP header and payload. This header is used to detect any modification to the content of the packet in transit, and to detect replayed packets. Then, the system encrypts the IP packet payload and some fields of the inserted crypto header. On the other hand, the system transparently intercepts each inbound IP packet, decrypts its encrypted portions, and then uses its crypto header to authenticate the packet. If the packet is properly authenticated, the system indicates it to upper protocols.To be transparent to applications, the security system part that processes inbound and outbound IP packets was implemented as a NDIS (Network Driver Interface Specification) intermediate driver that resides between the LLC (Logical Link Control) and MAC (Medium Access Control) data link sublayers.

هنالك العديد من الهجمات التي يمكن تنفيذها ضد اتصالات الشبكات المحلية (LANs). ألا أنه بالأمكان منع أو اكتشاف هذه الهجمات عن طريق توفير السرية للمعلومات المتبادلة، و التأكد من سلامتها و صدق مصدرها. يقترح هذا البحث نظاماً أمنياً يمكن استعماله لحماية شبكة محلية من الهجمات التي قد تستهدف أمنها. في كل حاسبة مرتبطة بالشبكة المحمية، يقوم النظام الأمني المقترح بمقاطعة مسار كل رزمة خارجة من نوع IP packet بصورة شفافة، ثم يقوم بادخال معلومات أمنية (crypto header) بين الـ IP header و الـ IP payload. تستعمل هذه المعلومات لكشف أي تغيير لمحتويات الرزمة أثناء تنقلها، و لكشف الرزم التي أعيد بثها. بعد ذلك، يقوم النظام بتشفير الـ IP Payload، و بعض الأجزاء من المعلومات الأمنية المضافة. من جهة أخرى، يقوم النظام بمقاطعة مسار كل رزمة داخلة الى الحاسبة بصورة شفافة، ثم يقوم بفتح تشفير الأجزاء المشفرة منها. بعد ذلك، يفحص النظام المعلومات الأمنية الموجودة في الرزمة المُستلمة للتأكد من صدق و سلامة معلوماتها. فأذا كانت الرزمة سليمة، يقوم النظام بتسليمها الى البروتوكولات العليا.لكي يكون النظام المقترح شفافاً للتطبيقات العليا، فأن ذلك الجزء من النظام الذي يعامل الرزم الخارجة و الداخلة تم تنفيذه كسواقة (NDIS intermediate driver)، و التي تقع بين طبقتي الـ data link layer: LLC و MAC.

Abstract

Aims: To evaluate the oral cleanliness and gingival health among intermediate school students and tofind if there was any variation between age and sex groups in Thamar–Yemen. Material andMethods: A sample of 596 students aged 13–15 years old (308 males, 288 females) were examinedusing plaque index score by Silness and Löe (1964) and gingival index by Löe and Silness (1963). Theclinical examinations were carried out in the school using plane mouth mirrors, WHO periodontalprobes to detect the dental plaque and gingival health. Results: The mean plaque score for the totalsample was 0.90. The plaque index was increasing with age, females reported less mean plaque scoresthan males with statistically significant difference between them. The mean gingival score was 0.52 forthe total sample and it was increasing with age with statistical significant difference. Females alsoreported less gingival scores than males with statistical significant difference between them. The study revealed that 45.1 % of the total sample did not brush their teeth. Conclusion: Gingival and periodontal diseases are indirectly related to the exposure of bacterial plaque for long time which calls for integrated, coordinated planning of preventive and treatment services as an urgent priority.

Abstract

Successful treatment of molar furcation defects remains a challenge in clinicalpractice. Knowledge of anatomic factors facilitates predictable management offurcation involvement lesions. Intermediate bifurcational ridge (IBRs) andcementicles are of those anatomical variations which considered as problems inprogression treatment of the disease.The present study was carried out to investigate the prevalence of IBRs andcementicles in Iraqi mandibular molars. The sample used in the study included 498extracted mandibular molars. The results revealed that the prevalence IBRs was306/498 teeth (61.44%), and that for the cementicles was 204/498 teeth (40.96%).The total sample was allocated into two groups:Group 1 included 313 molars (165 mandibular first molar and 148 mandibularsecond molar) , The teeth of group 1 were extracted because of caries andpulpal lesions, whileGroup 2 included 185 mandibular molars ( 98 first molar and 87 second molar).The reason of extraction of the teeth of group 2 was periodontal disease (differentdegrees of furcation involvement). For group 1 the results showed that 111/313(35.46%) of mandibular molars had attached cementicles in furcation area and185/313 (59.10%) were affected by IBRs. While in group 2 the percentage of bothanomalies was higher than that of group 1. In group 2 the results revealed that 93/185(50.27%) of the teeth had cementicles and 121/185 (65.4%) were recorded withIBRs.These results give an indication that the prevalence of cem. and IBRs highenough to be of clinical importance.
