Thus, the research aims to investgate the historical news, and the outstanding Zubarah figures who experience the supereme the religious, historical and scientific position in Khorasan generally and Nishapur particularily. It further aims at arriving at the true meaning of the name Zubarah, and to whom it was called, and the extent of this family’s affiliation to the noble Alawi House, and how they moved to live and settle in the cities of the East

إن الهويات الفرعية بإمكانها تقويض عمليات الاتصال والتواصل بين أفراد الثقافة الواحدة، إذا ما لم تكن هناك معالجات وخطط استراتيجية ذو أمد قصير وبعيد، إذ تعد عملية الاتصال بمثابة الرافد الوحيد لقيام ولاء وانتماء واحد ألا وهو الولاء للوطن.

    وتخشى بعض الدول من تفاقم الهويات الفرعية على حساب الهوية الوطنية، إذ تعاني مجتمعات أوروبا بعد ظهور داعش كمحتل في الشرق الأوسط، ليتم ربط كل ذلك مع العراق بشكل أ

زخرت رواية (دوامة الرحيل) لناصرة السعدون بتجسيد الصراعات النفسية والفكرية لابطال هذه الرواية وشخوصها ، والمواقف الحياتية ازاء الاخر المختلف بالدين او المذهب او الانتماء الوطني ، ولاسيما انها تعالج مرحلة خطرة من مراحل العراق بعد الاحتلال الامريكي له،  وما شهده من صراعات مذهبية وانتمائية فضلا عن حالة الفوضى التي عمت البلاد في اول مراحل ذلك الاحتلال ، مما شكل ازمة مستحدثة طفت على الساحة العراقية وهي ازمة ا

لا يمكن النظر إلى انص على أنه شكل واحد أو مضمون واحد  وانما هو كيفيات متعددة تختفي وراءها مقصدية المرسل وقصديته, وهذه الخلفيات تؤدي الى اختلاف استراتيجيات التأويل, لذلك وجد النقد الغربي ان معرفة مقاصد المؤلف هي خطوة اولى للحصول الى تأويل موضوعي, ولهذا  برزت اتجاهات مختلفة  في التأويلية منها ما يؤكد عدم محدودية التأويل ولا نهائيتها ، ومنها من يعتقد أنها طاقة مرتبطة بالتخييل لدى المؤلف والقارئ ، وهناك م

تمتلك كلّ ديانة نصوصاً دينية يُبيّن منها زعيمها الديني لأتباعها مقاصد ومرادات تلك النّصوص، وفي حال رحيله إلى الرفيق الأعلى، يقوم أوصياؤه والعارفين بها ببيان تلك النصوص وشرحها. وهكذا أتباع كل ديانة على مرّ العصور، يبحثون عمّن يوضح لهم ما غَمُضَ عليهم من نصوصهم المقدسة، وكذا الحال بأتباع الديانة اليهودية، فقد عنوا بنصوصهم المقدسة، كعناية المسلمين بالقرآن الكريم والسنة الشريفة؛ فتعدد قراءات النص الديني في

This research aims to distinguish the reef environment from the non-reef environment. The Oligocene-Miocene-succussion in western Iraq was selected as a case study, represented by the reefal limestone facies of the Anah Formation (Late Oligocene) deposited in reef-back reef environments, dolomitic limestone of the Euphrates Formation (Early Miocene) deposited in open sea environments, and gypsiferous marly limestone of the Fatha Formation (Middle Miocene) deposited in a lagoonal environment. The content of the rare earth elements (REEs) (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Ho, Tm, Yb, Lu, and Y) in reef facies appear to be much lower than of those in the non-reef facies. The open sea facies have a low content of REEs due to bein

This article proposes a new strategy based on a hybrid method that combines the gravitational search algorithm (GSA) with the bat algorithm (BAT) to solve a single-objective optimization problem. It first runs GSA, followed by BAT as the second step. The proposed approach relies on a parameter between 0 and 1 to address the problem of falling into local research because the lack of a local search mechanism increases intensity search, whereas diversity remains high and easily falls into the local optimum. The improvement is equivalent to the speed of the original BAT. Access speed is increased for the best solution. All solutions in the population are updated before the end of the operation of the proposed algorithm. The diversification f

The conjunctive ''and'' and its Arabic counterpart ''و'' are discourse markers that express certain meanings and presuppose the presence of other elements in discourse. They are indispensable aids to both the text writers and readers. The present study aims to show that such cohesive ties help the writer to organize his main argument and communicate his ideas vividly and smoothly. They also serve as explicit signals that help readers unfold text and follow its threads as realized in the progression of context. The researcher has utilized the Quirk Model of Semantic Implication for data analysis. A total of 42 (22 for English and 20 for Arabic) political texts selected from different elite newspapers in both Arabic and English for the analy

: Cigarette smoking is a lifestyle behavior that causes significant adverse health effects. Cigarette smoke contains chemicals, many of which are lead to the production of reactive oxygen species (ROS), which can lead to apoptosis and autophagy. To estimate the association of Cigarette smoking with the autophagy and immunity, technology of real time polymerase chain reaction (RTPCR) for gene expression of (LC3A, LC3B, LC3C, myd88) was used. Enzyme-linked immunosorbent assay (ELISA) technique was utilized to measurement the amount of TNF-α protein. The ratios of LC3A/LC3B and LC3B/LC3C were calculated to estimate the autophagy flux. The results indicate the expression of LC3B, LC3C and Myd88 genes in smokers is increased significantly (p

his paper uses the finite element method (FEM) to study a Surface Plasmon Resonance (SPR) refractive index sensor based on D-shaped Polarization Maintain Photonic Crystal Fiber (PM-PCF). A chemically stable plasmonic material, gold (Au), with hemispherical structures having a radius of 50 nm, is applied to the surface of a D-shaped sensor to create the surface plasmon resonance (SPR) effect, enabling this SPR sensor to detect variation in the surrounding analyte refractive index (RI). The resonance condition will change when the refractive index of the targeted analyte changes, leading to a certain shift in the loss peak. Two resonant peaks are observed, one located in the visible part of the spectrum, and the second in the near-infrared
