ملخص:قد حاولت الدراسة تبيين مدى تجلي تقنيات السرد الشعري الحديث: من خلال المنجز الشعري : "يا عنب الخليل" لعز الدين المناصرة ، فقد كان هذا النص أرضية خصبة يتحرك فيه السرد، وعلى ذلك قدم هذا البحث إلى فصلين الفصل الأول خصص للحديث عن تطور القصيدة المعاصرة بين حدود الشعر وتخوم السرد و فيه كان توضيح مدى الصلة القائمة بين الشعر، و السرد مساهمة السرد كذلك في قصيدة التفعيلة، كما أن المكان و الزمان عنصران أساسيان في العملية السردية لأنه لا يمكن الاستغناء عنهما، أما الفصل الثاني فقد كان للمقاربة السردية في المنجز الشعري : "يا عنب الخليل" لعز الدين المناصرة الذي كان زاخرا بعنصري الزمان، و المكان

Introduction: Bilateral sagittal split osteotomy (BSSO) is a standard technique in mandibular orthognathic surgery to correct facial asymmetries. Unilateral SSO was introduced as a less aggressive alternative limited to only one side of the mandible and with a narrow range of movement. Stress distribution on the condyles in USSO has not been addressed to determine symmetry of balance in this asymmetric procedure. Hypothesis/aims: The aims of this study are to evaluate: 1. the stress distribution on and displacement of the contralateral and ipsilateral neck of the condyles and menisci in simulated models of patients treated with USSO following graded movements of the mandible in advancement and setback; 2. the effect of condylar volume variation on stress distribution. The main hypothesis was that minimal stress would be registered on the operated condyle, and that a threshold should exist at which either advancement of setback mandibular movements should not be detrimental to condylar position and function. Methods: This retrospective study was conducted on 8 pretreatment CT scans of patients who presented for the surgical correction of mandibular asymmetry and who qualified for the USSO based on established inclusion criteria. USSO 3D movements (unilateral advancement and setback) in increments of 2 mm (from 4 to 12mm) were simulated in a finite element (FE) model and the corresponding stresses measured at the level of the temporomandibular structures (condyles and their respective discs and glenoid fossae). Stress distributions and displacements were analyzed for the different surgical movements through analyses of variance for group comparisons between advancement and setback and within the USSO variables, and correlation tests for associations among variables .Results: Stress and displacement at the condyle were higher on the non-operated than the operated side: highest on the anterior, posterior and lateral condylar surfaces, at the medial surface of the condylar neck, on the anterior condylar surface during setback, and posterior surface during advancement. The pattern of stress distribution suggested a lateral outward rotation of the condyle on the non-operated side. More displacement (up to 1.3mm) occurred at the non-operated than operated condyle. When condylar volume increased the displacement decreased. A balance of stress and displacement was observed at 6mm of advancement or setback before a new cycle of stress increase and decline. Increase in displacement was associated with increase in stress.Conclusions:1. This study was the first to contribute FE modeling and findings based on the individual variations among 8 human subjects who underwent USSO surgery.2. With increased surgical movements, statistically significant increase in stress was observed at the level of the condyles, condylar necks, and menisci on the operated and non-operated sides.3. The non-operated side disclosed most differences with incremental surgical movements.4. Individual velocity changes suggested a balance of stress between operated and non-operated sides between 4 and 6 mm of mandibular advancement or setback, which corresponded to the actual amount of surgical movement in the 8 patients under study.5. This research yielded a clinically testable hypothesis that should be explored in future FE models and direct clinical investigations. Significance: The significance of this research is the determination of the range of the surgical movements with the least and most stress on the temporomandibular structures thus the limits of mandibular displacement using the USSO.

This Study investigated (i) the causality relationship between economic growth and energy consumption and (ii) discussed the validity of EKC. The researched used data for 18 country from MENA region (Algeria, Bahrain, Egypt, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Saudi Arabia, Syria, Tunisia, United Arab Emirates and Yemen), using data for different periods for each country varying between 1971 and 2011. Data of energy consumption, real GDP per capita and CO2 emissions - as a proxy for environment degradation- was collected from the online database of World Bank. The researcher examined the linkage between these variables both across the region level and the country level. For this regard, and to avoid different characteristics among these 18 countries; countries with similar characteristics were compiled in different Panels, using the World Bank classification based on income level. High Income, Upper Middle Income, Lower Middle Income and GCC panels were constructed besides the Panel of the 18 country. Unit Root Tests were applied to examine the stability of data both for time series and panels; where all data was stationary. Then two different co-integration tests were applied as Pedroni test for Panel data while Johannsen Test for time series data. It was found that only 3 Panels are co-integrated (High Income, Upper Middle Income and GCC), at the country level only four countries have non co-integrated data (Libya, Qatar, Morocco and Oman). Therefore, the causality tests were applied only on co-integrated data as Panel Causality Test for Panel data and Granger Causality Test using the VECM for the time series data. Results were similar and showed no causality directions for the panel data. But for the time series, results were different as the direction goes from GDP to energy for Bahrain, Saudi Arabia, Iraq and Syria. Only one country showed bidirectional causality between GDP and energy consumption (Algeria). Many of these countries confirmed that no causality occurs between economic growth and energy consumption (United Arab Emirates, Jordan, Iran, Tunis, Egypt, Yemen, Lebanon and Israel). Only Kuwait confirmed the growth hypotheses; as energy cause economic growth. Regarding the validity of EKC, results confirmed that this concept is just a theoretical one, empirically results showed a poor evidence of the existence of EKC.
