Abstract
In semiotics, the denotative relationship is established between the three aspects of the sign, the object, and the interpretation of the same sign, and symbolic processes find endless meanings and this relationship classifies the symbolic, indexical and iconic species. Proverbs are taken from the context of a linguistic community that form multiple meanings and show gender construction. with semiotic studies, the significations of the opposition between man and woman in proverbs can be investigated. In this article, the concept of gender in proverbs of Tati language is investigated with Peirce's semiotic model in order to evaluate and analyze the reflection of their linguistic elements in all kinds of signs. Based on the result, Tati proverbs are mostly in the form of symbolic signs. The highest frequency is objectification and then otherness. The symbolic contrast between male and female gender and the discourse order and hierarchical position of this concept in the form of ideas of superiority/inferiority, value/worthless, human/animal, authoritarianism/weakening, center/periphery, self/other, norm/abnormal, friend/ Enemy and Dominant/Dominant have been classified and conceptualized. This opposition represents the idea of the otherness of the female gender and the superiority of the male gender over it as a dominant discourse. Based on this, the gender structure of this concept can be shaped in relation to the language type of Tat tribes of Northern Khorasan.

Abstract
The probiotic effects of Saccharomyces cerevisiae and Aspergillus niger on the feeding efficiency, body composition, ammonia excretion, blood serum enzymes and the intestinal microbiota of juvenile beluga, Huso huso was investigated. The fish (31.8±2.81g) were randomly allocated into 12 oval tanks at a density of 30 individuals per tank with three replicates for each treatment,. The fish were fed either a basal diet (as control) or the diet supplemented with S. cerevisiae and A. niger (2×106, 4×106 and 6×106 cells g-1) for 8 weeks. The results indicated that the probiotic supplemented diet at 6×106 (cells g-1) significantly improved FCR and other nutritional indicators compared to the control treatment (p<0.05). Significant improvements (p<0.05) were also observed in ammonia excretion and blood serum enzymes between treatments. Total viable fungus and Lactobacillus spp. count were significantly improved in treatment compared to control (p<0.05). These results indicated that S. cerevisiae and A. niger improved feeding performance and blood serum enzymes of beluga.

Abstract
Aims: Backpacks are the most popular means of carrying backpack among school going students, but long duration of backpack carrying might lead to MusculoSkeletal Disorders (MSDs) among them. The purpose of the present study was to determine if MSDs could be related to backpack carrying among school going students.
Method and Instruments: This cross-sectional study was carried out among 159 students selected by convenience sampling from four schools in Pars Abad city of Ardabil in Iran in Autumn 2019. A combination of two Nordic and Cornell questionnaires used to collect the data via self-reporting , an anatomical figure of musculoskeletal system was provided to mark the area of pain , and also the students’ body weight and weight of their backpack were recorded using a digital weighting scale. Data analysis was performed using SPSS-23 software by Chi-Square test and descriptive statistics.
Findings: Lower back, neck, and wrist pains were the most common pains, respectively. Based on the results of Chi-square test, none of the musculoskeletal pains were significant association with transport ways vehicles to school such as walking, cycling, by car except for ankle pain (P-value <0.05). However, students who walked to school reported a higher prevalence of MSDs.
Conclusion: According to the study’s results, there was only a significant association between “types of transport to school” with ankle pain among students who carried backpack during last 12 month. Hence, it is recommended that researchers consider other determinants of these disorders in future research.

Abstract
In a completely randomized experiment, the effect of Daphnia magna meal on growth performance and carcass composition of rainbow trout (Oncorhynchus mykiss) larvae (body weight 0.538±0.197 g) was evaluated for a period of 60 days. Five diets with the same protein content (crude protein 52.70%) were prepared, including two diets containing fermented daphnia meal T1 (20%), T2 (30%), two diets containing raw meal T3 (20%) and T4 (30%), and a basal diet without daphnia meal as the control. The bacterial species used for fermenting included five commercial probiotic species. Fermented daphnia meal brought about significantly higher growth and the lowest feed conversion ratios, viz. T1 (1.27 ± 0.35) and T2 (1.31 ± 0.46), in comparison with T3 (1.38 ± 0.37), T4 (1.41 ± 0.42) and the control (1.84 ± 0.69) (p<0.05). The result of carcass composition analyzes showed that the highest protein percentage (68.23 ± 0.48%) was in T2 and the highest percentage of fat and energy (11.26 ± 0.50% , 4761.63 ±48.88 Cal g-1) were in T4 (p<0.05). The overall results of this experiment indicated that daphnia could be considered as a suitable partial protein source in rainbow trout larval feed.

Abstract
In a paradigmatic shift, semiotics tends to poststructuralist approaches with phenomenological landscape. The result of this shift has been the emergence of subject at the center of enunciation by paying special attention to perceptive components and socio-cultural issues in the study of signs and language. In this perspective, the manner “ I” as subject encounters with “ other” undergoes diverse changes and new interactions come into play. New semiospheres emerge as a result of this encounter whose relations encompass interaction, contrast, exclusion, segregation and adjustment. This approach has been proposed by Eric Landowski –French semiotics theoretician- and is based on four main strategies including assimilation, exclusion, segregation and acceptation in case of identity. Thus, the main question of the present study is as follows: How is it possible to explain the semiotic place of culture as semiosphere and the type of interaction occurred between “Self” and “other” in discursive atmosphere of “Nasseri’s death” by Ahmad Shamlou? The purpose of this study is to investigate the type of their encounter (self –other) and their complex relationships in the so-called poem from the point of view of socio-cultural semiotics in order to explain the position of the cultural spaces that govern it. This study will pave the way to better understand the manner semiotic atmospheres interfere with each other and finally leads to the formation of central semiotic semiospheres at socio-cultural level.

Abstract
This research was conducted to determine the effects of garlic extract as feed supplement on the growth performance, body content, blood indicators and culture water quality of rainbow trout (Oncorhynchus mykiss) under stress ammonia. A total number of 156 fish (Average weight 18.37±1.43g and total length 12.27±0.52cm) were reared in twelve 50-L tanks for 60 days (First period: 50 days of feeding with different levels of garlic extract) and (Second period: 10 days under ammonia stress of 0.024 mg /L). Experimental included adding different levels of extract to base food, 0, 0.5, 1 and 1.5% (control, A1, A2 and A3, respectively). The growth performance was significantly higher in fish fed garlic extract supplementation than control. There was a significant difference in feed conversion ratio between different treatments, so that was obtained the lowest in A2 and the highest in control. Protein, immunoglobulin and cortisol concentrations were significantly affected by different levels of garlic. The end of the experiment period, the fish were kept in a close recirculation system for 24 hours. Water sampling was carried out every 4 hours. Water ammonia increased from 16 to 24 hours of the test. At the end of the experiment (time 24), the highest ammonia was obtained in treatment A3 (0.43). In general, the results showed that the addition of 1 to 1.5% garlic extract improved the growth performance and immune response in rainbow trout, while in the recirculation system, the water quality of the rearing environment was better in the control treatment.

Abstract
Power, through a linguistic model, redefines the underlying meanings that form behind the relations of substitution, companionship, and within a sign. an examination of the mechanisms of different texts shows that divine power, by influencing and influencing linguistic structures, represents different forms of transcendental hegemony. Given that Rumi's Mathnawī is one of the great mystical narratives, the main issue is how the hegemony of divine power articulates the structures of the language of mystical discourse and the manner of expression and function of different types of narrators and becomes a transcendence itself. Therefore, in the present article, after explaining the relationship between the language of discourse and narration with the critical discourse analysis approach, the effect of believing in divine power on the linguistic structure of discourse and the method of narration of different narrators has been investigated. The result of this research indicates that the hegemony of divine power, like the dominant transcendence from outside affects the structure of the language of discourse and the narrator's mind, in which case the author-narrator is inside the larger text of the universe. He has become one and he writes in the language of the transcendental. Divine power also, by means of tricks, regulates the style of the narrators' minds towards the commandments, and in this way, represents the ideology hidden behind the discourse and ruling the writer's mind.
1. Introduction
The power and ideologies in each discourse affect the macrostructures of the narrative and the syntactic structures of the language. Narrative texts represent different forms of power at the level of their language and narration methods. In mystical discourse systems, divine absolute power also creates the world and social, ideological and interpersonal structures. The influence of this belief can also be seen in the mystical language and discourse of the Rumi Mathnawī. Although the Mathnawī is a meeting place of various religious, theological, philosophical and mystical discourses, but the mystical vision of Rumi makes him consider the existence and actions of all beings as subject to divine power in the spiritual Mathnawī. So what is of special importance in the Mathnawī is the visible and hidden presence of God in the narration of Rumi and the mystical language of the Mathnawī. Therefore, relying on the hypothesis that discourse systems affect the linguistic and discourse structures of the text and also that the narrator has an ideological function, the present research tries to answer the following question: How does the hegemony of divine power affect the linguistic structures and mystic discourse of Rumi. Also, how does it affect the narration methods of different types of narrators in Mathnawī. Also, how Rumi was able to bring all the voices to a romantic silence in front of the voice of God.
2. Literature Review
In the descriptions and interpretations of Rumi's works and thoughts, it is mentioned that Rumi's attention to the issue of God's absolute power is mentioned. In the book Dar Sāyeh-ye- āFtāb, Pournamdarian points out the dominance of her right and will over the narrator and considers it close to the experience of revelation (Pournamdariyan, 2009). Bameshki, in the book Revāyat Shenāsi-ye Dāstānhāy-e Mathnawī, while pointing to this issue, considers the narrator (Rumi) under her control in the dominance of mystic states (Bameshki, 2014). Also, recently research articles have been done in this field; As in "Causal Relation in Mystical determinism of Rumi", divine power has been analyzed from the perspective of Rumi's mystical determinism (Foladi and Yousefi, 2006). In "The problem of freewill and determinism in Moulana’s thought", the level of human predestination and free will against God's power has been examined (Ebrahimi Deenani, 2010). Moharrami, in "Difference of Molavi’s Mystical and Theological Viewpoint on Determinism", while examining the difference between popular predestination and romantic predestination, comes to the conclusion that Rumi praised romantic predestination (Moharrami, 2010). Also, in "Criticism of power from Rumi's point of view", his approach to the issue of power and his critical orientation towards it have been examined and analyzed (Mohammedzadeh, 2009). Therefore, so far in the conducted researches, either they have not mentioned the issue of power or a political concept has been considered from it. However, the effect of the hegemony of divine absolute power and its transformation into a meta-narrator in the structuring of the mystical language and the way of narrating the types of narrators in Mathnawī have not been investigated and analyzed and the present study tries to pay attention to this issue.
3. Methodology
The current research is based on library sources and descriptive-analytical method and based on the approach of critical analysis of narrative discourse. This research tries to show the influence of the ideology of God's absolute power in explaining the ideological linguistic mechanisms of power and the general atmosphere of Rumi's narration by examining the narrator element in some Mathnawī stories. The most important innovation of the present article is the analysis of the mechanism of divine power in linguistic structures as well as the narration of narrators in Mathnawī.
4. Discussion
One of the characteristics of Rumi's Mathnawī is the interweaving of God's power in the language of narration and its mystical discourse, so that this power is reflected in the element of narrator and narration. The subject of which narrator or narrators express their story from which perspective, at what distance, with what degree of trustworthiness and with what language, is affected by the worldview, ideology and power of the Meta-narrator. Therefore, in the Mathnawī, the discourse system of divine power organizes the narrator's act of narration. Based on this, in the present study, by using the concept of power in the analysis of critical discourse, the influence of belief in the absolute power of God in Rumi's thought and the organization of the linguistic and discourse structures of the Mathnawī have been analyzed. For this purpose, different forms of the meta- narrator's presence in connection with the types of narrators, as well as focalization methods, perspective and angle of view, the level of narrator's reliability, etc., have been examined in Mathnawī.
5. Conclusion
In the mystical and religious discourse system, there is a superior power in existence. This superior power has been greatly expressed in the language and system of mystical discourse as well as in Rumi's style of narration. Examining the linguistic and discursive mechanisms of narrators' narration techniques in the Mathnawī shows different forms of trans-narrator hegemony. In the first appearance of the meta-narrator's presence, the narrator considers himself under the influence of a secondary author who is the main narrator and Rumi and other narrators and even the types of narration are all under his power. In the Mathnawī, from the perspective of the omniscient narrator, the narrator-author and the narrator-character are also completely surrendered to the meta-narrator and see themselves as worthless particles who wish to be connected to the sea of truth. Also, the interpretations that the author-narrator provides during some of the stories about meta-narrator are in line with emphasizing her unique power. Moreover, the centralization of the author-narrator about the ideology of the power of the meta-narrator is always constant, but the centralization of the narrator-characters is variable and multiple.

Abstract
Water is needed to providing proper hydration of membrane and its ionic conductivity in polymer electrolyte membrane fuel cells, but excess water accumulation known as flooding phenomenon decreases the passing way of reactants in the GDL and reaction sites on catalyst layer and increases mass transport loss and leads to performance loss of polymer electrolyte membrane fuel cells. In the present work, the two-phase flow in the cathode channel of transparent polymer electrolyte membrane fuel cell with single serpentine flow field is visualized by direct optical imaging in unsteady and time averaged states. Then the water coverage length ratio and the average of water coverage length ratio are derived as a scale of water content of the cathode channel in the unsteady and time averaged states. In the unsteady and time averaged states, by increase the stoichiometry, decrease the relative humidity and inlet gases temperature in anode and cathode sides, the accumulated liquid water in the channels reduces. The effect of anode stoichiometry on the amount of water in the cathode channel in the unsteady and time averaged states is more than the cathode stoichiometry.

Abstract
In the present study numerical simulation of synthetic jet is performed to optimize geometric parameters and excitation frequency to maximize mass flow rate and velocity of the jet and to avoid separation on the airfoil. Geometric parameters include: diameter and height of the cavity and orifice and excitation frequency of diaphragm which are selected as variable parameters for optimization. Using Response Surface Method (RSM) in this research, the simulations for optimization of the momentum of jet flow are designed. After studies and initial simulations, the range of variations in the effective variable parameters for the maximization of the target function (jet velocity and mass flow rate) are determined. Then, using the RSM, 32 separate tests are defined based on geometric and frequency parameters to find a second-order relationship, which relates the target functions to their variable parameters and their interactions. In this case the RSM prediction for the maximum velocity and mass flow rate of the jet are 22.16 m/s 0.0006 kg/s, respectively. Using RSM to optimize the geometric parameters and excitation frequency, jet momentum increases considerably in comparison with the first simulation. The velocity, mass flow rate, and momentum of the jet are increased by 31%, 36% and 78%, respectively.

Abstract
Formulation of an edible coating based on gum tragacanth and chitosan was optimized for fresh apricots by Response Surface Methodology (RSM). The effects of the concentration of gum tragacanth and chitosan (independent variables) on soluble solids content, weight loss, titratable acidity, pH, reducing sugar, moisture content, and firmness (response variables) were studied. The results showed that the obtained RSM models were fitted for all response variables, except for soluble solids content and titratable acidity. Gum tragacanth and chitosan treatments significantly decreased the weight loss of the apricots during storage. The firmness of apricots was increased at higher concentrations of gum tragacanth. The pH of the apricots was lower at lower concentrations of gum tragacanth and chitosan. This work showed that the coating could improve apricot firmness and stability in terms of weight loss, pH, and moisture content during storage, and increase the commercial value of the product. To meet the desirable properties, the ideal concentrations of gum tragacanth and chitosan in the coating were 1.02 and 0.33% (w/v), respectively.

Abstract
Conceptual metaphor can be considered from modern linguistic theories that are concerned with metaphor in terms of meaning and connotation. This is fundamentally different with metaphor theory in classical literature. The new theorists see that the aesthetic of the metaphor is not confined to rhetoric and literature only, but also to meanings and connotations as well. In the related context, "Janson" and "Lykaf" are considered among the vanguard theorists in the field of conceptual metaphor who view the metaphor from a semantic perspective. In this research, and based on the descriptive-analytical method, we have studied the meaning of life in the poetry “Baland Al-Haidari”. And one of the most important findings that we reached in this article is that Al-Haidari mostly carries a pessimistic view that sometimes turns into absurdity. However, his poems may be interspersed with poems that carry a spirit of optimism in their folds accompanied by a glimmer of hope. Then Al-Haidari used the conceptual metaphor as a tool to express his viewpoint on the life that he lived with his flesh and blood. It can be said that the conceptual metaphor in Baland Al-Haidari's poetry stemmed from his bitter and tragic experiences in the reality of his life.
