Abstract

Background: This study aimed to compare the palatal dimensions in different occlusal relationships and to find outthe genders difference in each relationship.Materials and methods: The sample consisted of 60 sets of dental casts for 60 dental students and patients attendingthe Orthodontic Department in the College of Dentistry, University of Baghdad. These casts divided into three groupsaccording to the Angle's classification: Class I group: included casts of subjects had Class I normal occlusion andconsisted of 10 males and 10 females. Class II Division 1 group: included casts of subjects had Class II Division 1malocclusion and consisted of 10 males and 10 females. Class III group: included casts of subjects with Class IIImalocclusion and consisted of 10 males and 10 females. The palatal dimensions were measured using digital vernierand palatometer. Descriptive statistics were performed to each gender and to both genders in each class.Inferential statistics included independent sample t-test to find out the presence of genders difference and ANOVAthen LSD tests to show the classes differences in each gender and in the total sample.Results and Conclusions: The results showed that Class I and II males had the largest palatal dimensions than femaleswhile Class III females had the largest palatal dimensions than males. Class I subjects had the largest palatal widthand depth while Class II subjects had the largest palatal length. Class I males and Class III females had the largestpalatal width than other classes. Class III females and Class II males had the largest palatal depth than other classes

Abstract

Background: Maxillary sinus is the largest of the four paranasl sinus, among the paranasal sinus its plays an importantrole in the formation of facial contours. Therefore, knowledge of the development and size of the maxillary sinus maybe crucial for diagnosing and treating various cases of malocclusion. The purpose of this study is to evaluate theeffect of malocclusion in three skeletal classes on maxillary sinus dimensions.Material and methods: Total of 120 lateral cephalograms were derived from subjects with skeletal Class I, Class II, andClass III malocclusions, classified on the basis of the A-N-B angle. Each malocclusion group consisted of 20 males and20 females ranging in age from 12 to 16 years. Two linear measurements and three area measurements were madeto evaluate maxillary sinus size. The procedure was accomplished by mean of computer and Auto Cad program.Results: it had been found that maxillary sinus dimensions were significantly Larger in male than in females in differentskeletal malocclusion classes, skeletal malocclusion classes has no effect on dimensions of maxillary sinus except inmale class II skeletal malocclusion.Conclusion: Skeletal classes malocclusion has no effect on dimension of maxillary sinus except in male class II skeletalmalocclusion, male showed significantly greater maxillary sinus length, maxillary sinus height, and maxillary sinus areathan that of female in all skeletal classes.

Abstract

Aims: To compare the anterior and posterior facial heights among the sexes and total sample. Mean while; to find the facial height variations among the Class I, II and III dentoskeletal groups. Materialsand Methods: The sample comprised of 32 lateral cephalometric radiographs (16 for each sex) for each of the Class I, II and III dentoskeletal relationships. The age of the sample subjects was 15–20years. The lateral cephalometric radiographs were traced. The total, upper and lower anterior facial heights and the total, upper and lower posterior facial heights were measured. Results: No significantdifferences among the both sexes and total sample for the dentoskeletal groups were demonstrated. All the facial heights appeared significantly greater in Class II group than Class I group except upperanterior, upper posterior and lower posterior facial heights and was significantly higher than Class III group in upper anterior, lower anterior and upper posterior facial height. Class III group displayedsignificantly lower value in total facial height than Class I group and significantly larger value in lower posterior facial height than of Class I group and Class II group. Conclusion: The facial heights are notaffected by the sex variation, but there are certain variations in facial heights among the dentoskeletal groups.

Abstract

International relationships study has got a great attention paid by lots of academics and researchers. This study falls into this trend. It sheds lights on an important stage of Britain – Egyptian relationships. When Louzan – conference was held in 1922-1923 according on the request of Turkey and Alliance states to solve the oriental cause and to set the new border – lines of Turkey and to set a treaty that replaces the sever – treaty. Egypt has made use of concluding the conference in order to show its cause to the international world, by forming formal and informal delegations to conduct negotiations with Britain to solve the Egyptian Cause by Louzan – conference. But Britain had not allowed Egypt to attend the conference, and claimed its presentation in the Conference, as a part of its colonial policy.

حظيت دراسة العلاقات الدولية باهتمام بالغ من لدن الكثير من الباحثين والاكاديميين، وتأتي هذه الدراسة ضمن ذلك التوجه؛ وهي تسعى لتسليط الضوء على مرحلة مهمة من تاريخ العلاقات المصرية – البريطانية، فحينما عقد مؤتمر لوزان 1922-1923 بناءً على طلب من تركيا ودول الحلفاء لتسوية المسألة الشرقية، ورسم الحدود الجديدة لتركيا، وابرام معاهدة تحل محل معاهدة سيفر، استغلت مصر فرصة انعقاد المؤتمر؛ لإخراج قضيتها إلى النطاق الدولي من خلال تشكيل الوفود الرسمية وغير الرسمية، واجراء المباحثات مع بريطانيا؛ وذلك لحل القضية المصرية عبر اروقة لوزان، غير ان بريطانيا وكجزء من سياستها الاستعمارية في البلاد، ابعدت مصر عن المشاركة في مؤتمر لوزان وادعت تمثيل مصر في المؤتمر.

Abstract

A mathematical model is developed to express stress-strain relationship of normal-strength concrete confined by transverse reinforcement. The sectional ductility analysis on rectangular reinforced concrete columns is performed under axial load. Analytical modals available in the literatures for confinement concrete by different types of transverse reinforcement are used. A parametric study is performed to study the influence of these parameters on the curvature ductility of reinforced concrete columns. The main parameters introduced are the amount of longitudinal reinforcement, amount of transverse reinforcement, tie spacing and the level of the compression axial force. The experimental and analytical results available in the literatures are being compared with present study.
