Abstract: يتناول هذا البحث محاولة التعريف بجنس أدبي عرفه العرب في عصر ما قبل الإسلام، باسم (أساطير الأولين)، وقد برز فيه قاص عربي اسمه النضر بن الحارث. وقد جاء ذكر (أساطير الأولين) مرات متعددة في القرآن الكريم – في سياق محاججة القرشيين والرد على اتهاماتهم، وبوجه خاص الرد على النضر بن الحارث، القاص الذي ادّعى أن ما سمعه من القرآن الكريم ينتمي إلى هذا الجنس السردي. ويسعى البحث - في غياب نصوص ممثلة لهذا الجنس – إلى إعادة بنائه وإيضاح صورته، والكشف عن دور رائده النضر بن الحارث في تأسيس خطوات مبكرة في السرد العربي قبل الإسلام. ويقدم البحث تحديداً للمصطلح ولأبعاد الدلالة من خلال ثلاث رؤى: تتبع الإشارات القرآنية، وتدقيق الدلالة المعجمية، ومتابعة السياقات العربية (خارج القرآن والمعاجم). ويقدّم البحث صورة مقرّبة للقاص ولقصصه، وطبيعة مرويّاته، وصلتها بالقصص البطولي الفارسي، مما فيه ذكر لأبطال أسطوريين، كما يوضح البحث حضور السرد في إطار قضية التحدي. ويتابع البحث الأسئلة السردية التي وجهها النضر للنبي الكريم، وجاء الرد عليها في سورة الكهف (قصة أهل الكهف، قصة ذي القرنين) ويقدّم تحليلاً وظائفياً للخبر الذي سرد قصة النضر وأسئلته، مما يكشف عن مروية أخرى في سياق أخبار النضر وسرديّاته. ويجتهد البحث في ربط الموهبة الموسيقية والغنائية للنضر بتجربته السردية، كما يتساءل عن الطريقة التي كان يقدم فيها مروياته وقصصه الشفوية. ويختتم البحث بالتوقف عند مصير النضر بن الحارث، الذي أودت به عداوته، عندما تجاوز المجابهة بالسرد، إلى قيادة فرقة قرشية في معركة بدر، فأسر ثم قتل صبراً (إعداماً بالسيف) ويتساءل البحث فيما إذا كان مصير النضر قد أثر في مصير السرد العربي والنظرة إليه في الحقب التالية.

Abstract: صور من "التفاعل مع التراث" في القصة القصيرة العربية يسعى هذا البحث إلى إبراز صلة القصة القصيرة العربية المعاصرة بالتراث السردي العربي، ويتأسس على مكانة السرد العربي وتنوع أشكاله وأنواعه ووظائفه وتقنياته، كما ينطلق من أن الأنواع السردية العربية المعاصرة لم تنشأ من خلال عامل التأثر بالأدب الغربي والأجنبي وحده، وإنما استندت إلى ميراث سردي غني له مكانته ضمن تطور السرد العالمي. وليس هذا القول فرضا نظريا من دون دليل أو شواهد نصية، وإنما هو خلاصة أو نتيجة يمكن تبينها عبر تأمل مسيرة السرد العربي، والنظر في موقع القصة القصيرة ضمن هذه المسيرة، وكذلك يمكن تعميقه من خلال إبراز صلة قصتنا الحديثة والمعاصرة بنصوص ومكونات تراثية تبرز في كثير من نماذجها بصور شتى من التفاعل والتناص. وقد شمل هذا المنحى مسيرة القصة القصيرة الحديثة منذ بداياتها في مطلع القرن العشرين وحتى اليوم. ، مجلة التربية والعلم، جامعة الموصل، العراق، 2014.

Research Title: Stress Distribution at the Corners of Three Equal Spans T-Beam Continuous Skew Bridge and the Effect of Number of Spans on These Stresses

Author: Abdallah Ali Khaled Odeibat, Published Year: 2015

Faculty: Engineering and Technology

Abstract: Skewed bridges are commonly used structure;this study has investigated the effect of skew angle on the stresses affecting corners of three equal spans T-beams continues skew bridge and the effect of number of spans on these stresses.Nine three-dimensional finite element models with skew angles between (zero and 70o) with span length of (25m)were modeled using CSi Bridge software, all models were subjected to AASHTO HL-93 loading specifications. Analysis results showed that stresses on deck slab and corners increase with the increase of skew angle;transverse moments could be calculated by AASHTO approximate methods and should be multiplied by the proper fold value from tables in chapter four, where longitudinal moments reaches (72%) of transverse moments. Due consideration should be taken to torsional moments at end zones, where they reaches (82%) of transverse moments with extension of (0.34L) from supports at obtuse corners and (53%) with extension of (0.26L) at acute corners. Moreover, results show that maximum positive and negative bending moments in girders decrease with increase of skew angle, and the location of maximum positive moments moves toward obtuse corners supports in exterior and interior girders. However, shear forces increase with increase of skew angle except near acute corners in exterior and first interior girders; where shear forces decrease with increase of skew angle. Whereas; results also show that as skew angle increase, reactions increase at obtuse corners and decrease at acute corners, where maximum reaction values were concentrated interior girders supports. Comparing this study results with previous study of two-span bridge results,it shows an alternate effect of number of spans on deck slab stresses, girders moments and shear and reaction forces.

Research Title: ISENTROPIC SOUND PROPAGATION ANALYSIS AND OPTIMIZATION OVER FLAT PLATE OF SATURATED POROUS MEDIA WITH VARIABLE PERMEABILITY

Author: Laith Batarseh, Published Year: 2011

Faculty: Engineering and Technology

Abstract: The problem of sound propagation over flat plate of porous media was investigated at both stationary and movable flow conditions with a simple geometrical interfere where the permeability is assumed to be exponentially decaying in the normal direction and the thickness is optimized according to the maximum attenuation. It is found that the main parameters affect the propagation process are:- porosity; ε, static permeability; Ko and the steady flow Mach number; . In addition, it is found that the new interfere of the permeability can improve the attenuation of sound wave when it is combined with the porosity and steady flow parameters beside the minimum required thickness. Also, the minimum required thickness depends on static permeability, porosity and flow state

Research Title: Permeability Effect on Sound Wave Propagation in Saturated Porous Layer Lied Over Flat Plate

Author: Laith Batarseh, Published Year: 2011

Faculty: Engineering and Technology

Abstract: In this research, the effect of varying permeability on none – isentropic sound wave propagation in porous layer lied over flat plate was under investigation. The continuity, momentum and energy equations were derived, linerized and solved respectively by using the hydrodynamic / acoustic splitting method, the suitable variational solution and Euler – Lagrange approach. The effects of viscosity and thermal gradient were involved. The media was assumed to be formed by spherical particles with small diameter. The permeability was varied exponentially by varying the particle diameter and applying Carman – Kozeny relation to relate porosity and particle diameter to permeability. Both attenuation and phase velocity were found for both cases of stationary and movable flow situations. It was found that the effective parameters on propagation constant are: initial value of particle diameter (Dpo), initial value of porosity (εo) and the mean Mach number ( ). Both initial values of porosity and particle diameter have retarding effects on attenuation and enhancement effects on the phase velocity for all wave types. It is also found that as the flow velocity increases, attenuation for both forward and hydrodynamic waves decreases and the phase velocity increases while the opposite occurs for the backward wave where the attenuation increases and the phase velocity decreases.

Research Title: Numerical investigation of fully developed laminar flow in irregular annular ducts: Triangular–circular combinations

Author: Laith Batarseh, Published Year: 2014

Faculty: Engineering and Technology

Abstract: The aim of this study is to reduce the required pumping energy by obtaining accurately the friction factor - Reynolds number product (fRe) of the steady fully developed laminar flow in annular ducts. The study is focused on the annular region between equilateral triangular and circular ducts under all possible combinations. For this purpose, the governing equations are solved using high order finite element method. For regular annuli, it is found that higher values of area ratio lead to monotonic increase in (fRe) value, with (fRe)(max) = (24, 42.67,96) at the respective values of (D-h)= (0.5,0.75,1) regardless of the particular geometry. For irregular annuli, higher values of area ratio lead to an increase followed by a decrease in (fRe) value, with (fRe)(max) = (79.631,35.392,19.921) at the respective values of (D-h) = (0.5, 0.75, 1) for the (CT) case, and correspondingly (fRe)(max) = (91.02,40.45,22.85) for the (TC) case. On the other hand, it is found that (fRe) value inversely proportional with the hydraulic diameter (D-h). For all cases considered in this study, the largest (fRe) at the representative values (AR) = 30% is found for the (CC) case with (fRe)(max) = 95.43 whereas the smallest (fRe) is found for the (CT) case with (fRe)(min), = 17.544. More importantly, irregular annuli outperformed the regular annuli and thus are recommended to replace the classical regular annuli currently used in double duct heat exchangers. This in turn will significantly decrease the pumping energy required in such applications in industry.

Research Title: Innovative Wind Turbine Selection Method Using Modified Weibull Probability Function

Author: Laith Batarseh, Published Year: 2015

Faculty: Engineering and Technology

Abstract: In this work, a three-year wind data for some sites in Jordan was analyzed. Two sites showed highly promising potential. Both predicted more than 1.0 MWh/m2.y. This work modified the probability function of Weibull – Hiester and Pennel to produce more accurate potential speed values for the wind. Results showed that this modification enhanced energy potential by 30%. The interaction of wind turbine performance data with site wind data was then discussed. The yearly output energy of different machines was the objective function for an optimization process with rating velocity (Vr) as the main variable. The resulted optimum energy was found to depend on the two variables of the Wiebull function. Optimum Vr was found to range from 4.2 to 5.6 for the sites considered. The optimum Vr can be used as a selection parameter for the best suitable turbine.

Author: Nabil Musa Wanas, Published Year: 2014

Faculty: Engineering and Technology

Abstract: Abstract. In this paper, interaction of discontinuous waves with hyperboloid heterogeneities in anisotropic elastic media is investigated. It is shown that the interactions are accompanied by formation of reflected and refracted quasi-longitudinal and quasi-shear discontinuous waves which can be focused or scattered by elastic "mirrors" and "lenses" depending on their geometric outlines and acoustical properties. The set up problem solutions can be used for discovering the most and least seismically hazardous zones in the earth crust and for interpretation of geophysical data about geological rock structures.

Research Title: Mec A and PVL Genes in Methicillin Resistant Staphylococcus aureus from Nasal Carrier Individuals Exposed and Not Exposed to Hospital Environments.

Author: Raida W. Khalil, Published Year: 2009

Faculty: Science

Abstract: Exposure to hospital environments of limited duration did not cause an increase in the nasal carriage of Staphylococcus aureus whether they are methicillin resistant or sensitive. 56% of MRSA isolated were resistant to erythromycin and lincomycin and more than 50% of those are resistant to gentamicin as well. No vancomycin resistance was encountered. Resistance to other anti-microbials was uncommon among MRSA. One MRSA strain possessed the pvl but not mec A gene. All other mec A positive strains did not have the pvl gene.
