Storytelling is one of the important strategies in the Holy Qur'an to express its teachings. In this literary-artistic style, the Qur'an tries to stimulate religious feeling and human consciousness. One of the most important and fascinating stories of the Qur'an, which is illustrated for the educational purposes and the propagation of values, is the story of the Prophet Solomon and the Queen of Sheba. In the present study, the story is interpreted with a semiotic approach with the aim of explaining the Qur'anic concepts and applying them, as well as understanding the methodology of the Qur'an in producing discourse. With such an objective, it answers the question of how the process of meaning creation occurs. The narrative structure in the text is such that the performance function controls the process of creating meaning. The findings showed that the performance function governing this story shapes the performance discourse system. The nature of this system is shaped by the elimination of the crisis of meaning (polytheism). In this system, the strategy of acquiring a valuable object has both an operational and a programmatic aspect. Solomon and his activists achieved the object through a process of competence-performance and step-by-step operation, moving the Sabaeans from the first meaning (polytheism and lack of faith) to the second meaning (monotheism and godliness). In this way, with Solomon's soft power, the polytheistic political system in the land of Sheba is transformed into a monotheistic political system.
          
1. Introduction
The narrations of the prophets are rich and unique collections that have the capacity of the semiotic study. These stories are mentioned in the Qur'an in order to awaken both the human and society and bring them closer to the ideal situation. In fact, the art of storytelling in the Qur'an is considered as a strategy to propagate the values and intellectual development of the society.
Since the main purpose of the Holy Qur'an is to convey messages in line with the human guidance, it cannot be claimed that the narrations in the Qur'an have only aesthetic and artistic functions. Accordingly, the semiotic necessity of the Qur'anic narrations as well as the method of creating meaning so as to produce discourse are of special importance. One of these unique narrations, which is depicted with the aim of belief and political education with a special artistic technique, is the story of Solomon and the Queen of Sheba. The present study aims to explain the managerial role and the soft power of Solomon as well as the credibility of the Queen of Sheba in order to analyze the discourse functions of the story. The main issue of this study is to find the role of cognitive presence in how the Queen of Sheba believes and reaches the object of faith. The present study aims to explain the Qur'anic concepts and to apply them and to understand the Qur'anic method in producing discourse, as well as to explain the managerial role and the soft power of Solomon and the credibility of the Queen of Sheba, in order to analyze the discourse functions of the story.
 
2. Purpose, Questions and Hypotheses
The present study aims to explain the Qur'anic concepts and to apply them and to understand the Qur'anic method in producing discourse, as well as to explain the managerial role and the soft power of Solomon and the credibility of the Queen of Sheba, in order to analyze the discourse functions of the story.
This article seeks the answers to two questions: A. What kind of system does the governing process of the story of Solomon and the Queen of Sheba create in the Qur'an? B. How is an attachment with an object of value obtained? It is assumed that the the performance function makes the performance-oriented discourse governing and the actors achieve the object of value through a step-by-step operation and a narrative performance process.
 
3. Innovation

Because semiotics provides a methodological and coherent framework for the study of prolific texts, the narrative domains of the Holy Qur'an also provide the basis for such studies. Researchers have taken advantage of this opportunity to write in the field of semiotics in the Qur'anic stories.

Qur'anic performance-oriented discourses have not been studied yet. The present article attempts to study and analyze one of the most beautiful stories of the Qur'an focusing on the performance and manner of the presence of the actors.

4. Methodology
This article analyzes the discourse functions of the story of the Prophet Solomon and the Queen of Sheba with an analytical-inferential method and a semiotic approach.
 
5. Results
The findings suggest that the performance function governing this story shapes the performance discourse system. The nature of this system has been shaped by resolving the crisis of meaning (polytheism). In this system, the strategy of acquiring the object of value has both operational and programmatic aspects. Different ways of the presence of the actors, on which the creation of meaning depends, are tied to the modal verbs, and the performance obtains results through the process. In this action system, polytheism and sun-worship are a crisis that has led the people of the land of Sheba to break away from the object of value of faith and monotheism. The Prophet Solomon uses his soft power to lead the people of Sheba to the valuable object of monotheism and to resolve the crisis. He achieves the goal through a step-by-step operation and a performance process, which he is in the center of it, accompanied by the actors, and connects the Shebans to the object.In this programmatic operation, meaning changes from a negative state of unbelief to a positive state of faith in God.Thus, with Solomon's soft power, the political system based on polytheism in the land of Sheba is changed to a political system based on monotheism

In the current study, the streamline simulation technique is used for definition of a new objective function to optimize the production rates during water injection process. The streamline simulation technique, in comparison with common numerical methods for simulation of multi-phase flow in porous media, is much faster with less computational memory requirement. This method represents the key parameter of “Time of Flight” which helps to consider complex heterogeneity of porous media in a more easy way. In order to optimization of oil production rates from reservoir, a function based on averaged time of flight has been introduced which minimization of this function can be used to have uniform fronts of water for flooding of oil. For this target, two optimization techniques; the Artificial Bee Colony (ABC) and the Sequential Quadratic Programming (SQP) method are employed to optimize the objective function and their results are compared with each other. Advantages and disadvantages of these two methods are investigated and based on their advantages, a new hybrid approach is proposed which utilizes the benefits of both techniques to converge to the optimum solution. In the hybrid approach the SQP algorithm is initialized with the ABC method. In order to validate the mathematical model, a 2D homogeneous model used for optimization. Next a 2D heterogeneous model and a 3D complex reservoir model are investigated. In all the mentioned problems, it is observed that the hybrid approach, in comparision with the two other methods, can approach the optimum point with better accuracy and speed.

In this paper, the non-Newtonian immiscible two-phase polymer flow in a petroleum reservoir has been investigated numerically. The fluid flow in a porous medium is simulated as a compressible flow. The Carreau-Yasuda constitutive equation is employed as the model of non-Newtonian fluid. The IMPES method is used for numerical simulation, in which the pressure equation is discretized and solved by an implicit approach and the saturation equation is solved by an explicit method. Results reveal that zero-shear rate viscosity has a high impact on the sweep efficiency of the reservoir and also controls the channeling and viscous fingering effects. In addition increasing the viscosity of non-Newtonian fluid improves cumulative oil production and diminishes the viscous fingering phenomenon caused by injected fluid. The relaxation time of Carreau-Yasuda fluid, which is the elastic characteristic of the non-Newtonian fluid, for low permeability values cannot influence flow characteristics inside the reservoir, however for higher permeability values its effect becomes more sensible. Increasing the injection rates leads to the increase of fluid production, while the injection rate has an optimum range to reach the optimum oil production. In addition, the effect of variation of the injected fluid properties on the polymer breakthrough time has been investigated and results presented.

Heavy oil and tar sands resources comprise about 70 percent of the world's oil reserves and this reservoirs can offset the declining production from conventional reservoirs. Thermal enhanced oil recovery (EOR) methods are employed to exploit the huge reserves of heavy oil due to their high viscosity values. Thermal processes aim to increase its mobility in order to improve its production. Among these methods, the steam-assisted gravity drainage (SAGD) is one of the most efficient techniques. In this method, two horizontal wells are drilled and hot steam is injected from a well to move oil toward the other well. Optimization of operating parameters during this process is very important. The injection rate or pressure control of wells are the most common EOR methods. In this paper for the first time, in addition to the injection rate of the injector and production wells, the steam injection temperature is also optimized. It was shown that there is an optimum amount for the temperature of injected steam. In addition entropy generation analysis was performed for different cases. To simulate the process, a commercial software was used and optimization of operating parameters is performed using the pattern search algorithm. Entropy generation calculated based on the results of numerical simulations using a computational code has been written for this case. The results show that the maximum oil production corresponds with the minimum entropy generation number and thus the entropy number can be used as an appropriate objective function in order to enhance oil recovery.

Prison literature is one of the branches of literary criticism that has been shaped by various political and social currents and narrating the sincere feelings of those who have often been detainedand persecuted for seeking freedom. Reza Barahani (1935) and Abdul RahmanMajeed al-Rubaie (1939) are the contemporary writers of Persian and Arabic literature who are pioneer in this field. The novel Bad az Arose cheGozasht(What happened after the Wedding) describes the harsh and insulting attitudes of SAVAK officers with political prisoners in the form of noble character Shahir and reflects the political atmosphere in the era of Mohammad Reza Pahlavi.  The novel Alvashm also presents an image of the defeat of the first republican system and the return of tyranny to Iraqi society between 1958 and 1963, in the form of Karim al-Nasri's personality. The present study, using a descriptive-analytical method and based on the American Comparative Literature School, examins and compares the two selected novels from the perspective of the prisonliterature and concludes that the purpose of both writers was to draw the intellectual space and the way governments then interacted with intellectuals in Iran and Iraq, with this difference that the political condition of the two countries have brought different outcomes for the heroes.
