Abstract
Folk tales are among the fascinating and dynamic forms of folk culture and literature reported in oral and ancient tales. Farahvar is one of the most prominent concepts in mythological and epic beliefs revealed by folk stories. However, obvious examples of the kings of Farahmand in mythology and the epic types have inherited their form, but this form is not the only way to acquire the character of Farahvar. By adopting a descriptive-analytical research methodology, this article attempts to reveal the nature of Farvahar in a collection of four volumes of Iranian stories. The study of Iranian stories and the extraction of many examples from the stories showed that the nature, the manifestations, the forms and the characteristics of Farvahar retain their mythological functions in the Persian narratives. Farvahar is often inherited from stories, and there are examples of this gift taken temporarily or permanently from the king. However, the promising ideas of folklore in the context of narratives allow the lower strata of society to reach the level of monarchy. It should be noted that the spirituality that exists in the stories of Farvahar and the tales, and the luck of the individuals is also a platform for the emergence of archetypes of the model

Abstract
Aims: In this research, we investigated the effects of stocking density on growth performance and survival rate of Persian sturgeon and Beluga.
Materials and Methods: Stocking densities for treatments 1-5 of Persian sturgeon in stages 1 were 6, 8, 10, 12 and 14 fish/l (initial weight: 116mg) and in stage 2 were 1, 2, 3, 4 and 5 fish/l (initial weight: 2218/6mg). Stocking densities of five months old Beluga juveniles (initial weight: 109.95g) for treatments 1-5 were 80, 100, 120, 140 and 160 fish/m3 in each 250-liter tank respectively.
Findings: Growth and feeding parameters were affected as the stocking densities increased in both species. In stage 1 in terms of weight, SGR and food efficiency, treatments 1 and 2 showed significantly higher values (p<0.05) comparing with treatment 5, treatments 4 and 5 and all treatments respectively. In stage 2, there are significant differences amongst the all treatments in terms of weight and SGR except treatments 3 and 4. Food efficiency in treatment 1 was significantly higher (p<0.05) than the rests except treatment 2. In Beluga, there were significant differences amongst all treatments except treatments 3 and 4 in terms of weight, SGR, and food efficiency and the highest values were observed in treatment 1.
Conclusion: The best stocking densities for stage 1 and 2 of Persian sturgeon were 8-10 and 1-2 fish/l respectively and for Beluga, juveniles were 80-100 fish/m3.

Abstract
Aims: Due to vital role of optimum feeding rate on success and profitability of an aquaculture practice, feeding rates were examined in different life stages of Beluga sturgeon.
Methods: Feeding rates were 5%, 7%, 9%, 11%, 13% and 15% in stage 1; 2%, 4%, 6%, 8%, 10% and 12% in stage 2; 1.5%, 2%, 2.5%, 3% and 3.5% in stage 3; 1.5%, 1.75%, 2%, 2.25% and 2.5% in stage 4. Farming durations of stages 1 to 4 were 10, 10, 42 and 56 days, as well as initial mean weights were 1.85, 7, 112.04 and 300.54 g, respectively.
Findings: Results showed that optimum feeding rates from growth and feeding parameters point of view were 9% and 5%, respectively, in stage 1. In stage 2 also optimum feeding rates were different from growth and feeding point of view, as they were 4% and 2%, respectively. For both aspects of growth and feeding parameters, optimum feeding rate was 2.5% of body weight in stage 3. In stage 4, the lowest food conversion rate was observed in the feeding rate of 1.5% and there were no significant differences between treatments from growth parameters point of view.
Conclusion: Growth and feeding parameters were affected with feeding rates in stages 1, 2 and 3. In stage 4, feeding rates influenced feeding parameters, but had no significant effects on growth performance.

Abstract
The existence of a crisis such as a climate change and greenhouse gas emissions, due to the excessive consumption of energy and the share of buildings in it, is one of the global problems that is undeniable. On the other hand, the influence of geometric indicators on thermal behavior has been experienced over decades in the nature of animals and plants. Historically, Architects have always tried to create appropriate solutions with the intention of providing a comfort zone for human in line with the climate. Choosing the form and scales are from the solutions adopted.
This study tries to study the contribution of each of the effective geometric indicators by using a software simulation method as well as being a step to provide the principles for choosing the volumes by architects and designers. With this purpose and with studying the previous researches, the most important indicators and used methods were identified and selected. 10 volumes including 5 simple volumes and 5 volumes of the compound that are more abundant among other residential forms, especially in hot and arid climate, were selected in four floors with residential use. The contribution of each geometric indicator has been investigated by simulating the thermal behavior of each volume in Autodesk Ecotect Analysis software and Design-Builder software.
The simulation results indicate that after the form of the building, the relative compaction indicator, and then the proportion of the surface of the south facade are more important. In addition to geographic indicators, east-west orientation provides the optimal response to the total annual energy consumption of the building.

Abstract
Functional response is an important behavioral characteristic of prey-predator interactions that can be utilized for assessing impact of natural enemies. In this research, the functional response of Nabis pseudoferus Remane females was examined to the third-instar larvae of Tuta absoluta (Meyrick) which were exposed to LC30 (2.03 × 10
4 conidia/ml) values of
Metarhizium anisopliae (Metschnikoff) Sorokin isolate DEMI 001. Six densities of the prey (1, 2, 4, 8, 10 and 16) were exposed to the predator (0, 24, 48 and 72 h) after inoculation.
N. pseudoferus exhibited a type II functional response to prey density in all treatments, indicating that predation increases asymptotically to a satiation level. The highest and the lowest attack rates (
a) were 0.1052 ± 0.0440 and 0.0509 ± 0.0133h
-1 for 48h and 72h post-infection treatments, respectively. Maximum theoretical predation rate (
T/Th) was estimated 10.96 in control. Our results suggest that
M. anisopliae and
N. pseudoferus, can be a useful combination in pest management of tomato leaf miner, although it must be confirmed in field condition.

Abstract
Pistachio endocarp lesion (PEL) is one of the most important disorders that has spread in the pistachio-growing regions of Rafsanjan and Anar in recent years and has caused great economic losses to farmers. In order to identify PEL symptoms, and investigate the biologic factors involved in the development of this disorder, on May 2016, 90 orchards with different levels of PEL, were randomly selected. The rate of development in each tree was scored in- to four levels. The incidence of this disorder was estimated to be 25.8% in Rafsanjan. The seeds with PEL symptoms were differentiated into six types based on the appearance of the symptoms. Then tissue from infected parts of each type were cultured in the PDA. From among the 18 prepared culture media, fungal growth was obtained only in five cultured plates. Isolated fungi were Ulocladium sp. Penicillium sp., Verticillium sp. and Fusarium sp. To prove their pathogenicity, the spore spray technique was used on detached cluster in vitro. None of the purified fungi caused symptoms similar to the symptoms of PEL. Isolated strains from the pistachio seeds with PEL symptom often were saprophytic and soil borne; they were abundant in the orchard and could be transferred to the shoots of trees under the influence of various factors, such as: tillage, soil splashing by rain drops, and wind. In this study, the role of these fungal agents on the development of PEL was rejected.

Abstract
The realization of the argument structure of nouns corresponding with ditransitive verbs is a complicated subject since those nouns involve categorical, morphological, syntactic and semantic features of both nouns and verbs. The aim of this article is to survey the argument structure including categorization, syntactic structure and phonetic and semantic realization of main ditransitive verbs and their corresponding nouns in Hawrami Kurdish-a north western Iranian language. Dividing and describing the nouns into possessive and agentive nominals, this article analyzes and contrasts them with corresponding verbs under the framework of MP/DM. The results show that syntactic structure of main verbs and their corresponding nouns involve verbal category (VP) to introduce theme and low ApplP to introduce benefective goal or location. The subject of the sentence merges as the possessor in EzafPposs of possessive nouns and as the same agent in VoiceP of agentive nouns. The heads of the TP and CP select vP in statements; hence, the heads of PEP and DP choose nP in nominals. The root in possessive and the whole VP features in agentive nominal move to np and PEP to value their nominal and Ezafe features. Agentive nouns have more nominal properties and take plural, (in) definiteness, possessive and adjectival markers and also do not take manner adverbs. Therefore, argument structure analysis of nouns corresponding with ditransitive verbs using the MP/DM approach shows that syntactic structure is the driving engine for the categorization, syntactic structure and phonetic and semantic realization of possession and location transfer of ditransitive verbs and their corresponding nouns in Hawrami.

Abstract
Ooencyrtus fecundus Ferriere and Voegele (Hymenoptera: Encyrtidae) is a gregarious egg parasitoid of sunn pest Eurygaster integriceps Puton. Superparasitism enables a female to produce multiple progeny per host and thus reduces the time spent searching for hosts, but results in progressively smaller progeny as more individuals compete for limited resources within hosts. In this study, we tested whether gregarious development would affect the functional response of O. fecundus reared under laboratory condition (26 ± 2 ºC, 50 ± 10% RH and 16: 8 L: D h). Various host densities (1, 2, 4, 8, 16 and 32 eggs) were offered to females that had developed either as single, or as twins, triplets or quadruplets within host eggs. To resolve the functional responses of these females, a total exposure time of five hours was chosen, based on direct observations of handling time and the maximum daily number of host attacks/female. Functional response of the parasitoid was type III in singleton and twin parents, and type II in triplet and quadruplet ones. However, host mortality rate was 100% in host densities ≤ 8, suggesting density independence at lower densities as expected from a type I functional response. In such circumstances, handling time is expected to be zero, but was observed to be 11.4 to 14.3 minutes in different treatments. These results suggest that when enough time was available to find and handle all hosts, a type II functional response resembles Type I one. Searching efficiency increased and handling time decreased with body size of the parasitoid of four categories.

Abstract
Baryscapus evonymellae (Bouché, 1834) (Hymenoptera, Eulophidae) was rediscovered on Leucoma wiltshirei Collenette, 1938 (Lepidoptera, Erebidae) attacked by different parasitoids. This species had already been reported under different names; therefore, its inaccurate identifications were corrected. It was reared as a larval and pupal hyperparasitoid of two important primary parasitoids of L. wiltshirei including Brachymeria tibialis Steffan, 1958 (Hymenoptera, Chalcididae), and Dolichogenidea persica Abdoli, Mohammadi, Sedaratian-Jahromi & Farahani, 2023 (Hymenoptera, Braconidae). The last parasitoid-hyperparasitoid association is new. Its morphological characters were illustrated and its biological data and main characteristics were discussed.

Abstract
Aims: Three-dimensional (3D) cell culture systems are important because simulating the physiological microenvironment and representing more similarity to “in vivo” conditions for anticancer drug screening. Taking the advantages of 3D cell culture in the cancer therapy field, we have developed the 3D in vitro anaplastic thyroid cancer (ATC) model for determining the cytotoxic dose of "BI-847325" chemotherapy agent in ATC cell lines with different genetic background.
Materials and Methods: C643 and SW1736 ATC cell lines were grown in alginate scaffold. Beads were incubated in medium for one week. Cells were treated with different doses (1-64μM) of BI-847325 for 24h. The cytotoxic effect of BI-847325 on 3D cultured cell lines was studied by MTT [3-(4, 5-dimethyl thiazolyl-2)-2, 5-diphenyltetrazolium bromide] assay. The survival rate of alginate-encapsulated cells was analyzed by CFSE (5, 6-Carboxyfluorescein N-hydroxysuccinimidyl ester) staining in effective doses for each of the cell lines.
Findings: Cytotoxic effect of BI-847325 anticancer drug was different for two ATC cell lines. Effective doses of BI-847325 for C643 and SW1736 cell lines were at 25μM and 43μM, respectively. CFSE staining analysis confirmed these data.
Conclusion: Overall, the results of the present study showed that the cytotoxic effect of BI-847325 chemotherapy agent was different for two ATC cell lines. The importance of this subject in regard to the 3D cell culture methods can be useful for researchers in the design of the complementary experience in order to achieve the most appropriate chemotherapy drug with the most effective dose.

Abstract
Aims: Residential use prevents effective communication between the monument and the audience, therefore the new type of use that is assigned to them during the restoration process is significant. The main purpose of this article is to analyze the adaptive reuse of the Tehran valuable houses by Tehran Beautification Organization and Municipality of Tehran based on the place-based contemporization model.
Materials & Methods: The qualitative research method is adopted based on the "synchronic discourse analysis". By examining the place-based contemporization approach, the participation of all stakeholders and influential people is inevitably divergent. Considering different groups in nine case studies of changing the use of historic houses in Tehran, the quality of the neighborhood is analyzed with the approach of the article. The process of changing the use of historic houses was also explained based on this model.
Findings: In all cases, developmental discourse, including local restoration, quality enhancement and development stimulus has a higher score than all other discourses. The discourse of unconscious reproduction involves the use of place and interactions and experiences after developmental discourse is important.
Conclusion: In the highperformance architecture theory, contemporization and reuse of the valuable houses in Tehran with the approach of the article can make these houses a better place and link them to the neighborhood. The conclusion highlighs the successful record of the Tehran Beautification Organization and the Municipality of Tehran in contemporization of the Tehran valuable houses; as well as benefits and drawbacks.

Abstract
A recirculating hatchery system (RHS) and a flow-through system (FTS) in terms of major macro elements (Ca, Mg, Na and k), some microelements (Fe and Cu), total bacteria and quality characteristics of Rainbow trout eggs and larvae were comparatively studied. A recirculating system (RHS) and a flow-through system (FTS) were designed for incubating the eggs and rearing the yolk-sac larvae. Fertilized eggs were distributed (5000 eggs in each tray) in four replicates and incubated under the standard conditions until yolk sac absorption. Total bacteria and macro/micro elements were measured at one-week interval. Eyed egg percentage, hatching rate, growth, and survival rate of larvae were measured. In the FTS and RHS, percentages of the eyed eggs were 79.75% and 79.01% respectively, and hatching rates were 70.31% and 63.65%, respectively. There were no significant differences amongst the values of Ca, Mg, and Na during the experimental period and between two systems. K Values in the RHS were significantly higher than in the FTS during the egg incubation period. Fe Values in the RHS were more than in the FTS, and increased during the study period in both systems. The values of total bacteria in the RHS were significantly higher than in the FTS. Despite the differences observed between the experimental systems, the designed RHS can be used for incubating the eggs and rearing the yolk-sac larvae in rainbow trout hatcheries, because of its simplicity, low water consumption, and acceptable efficiency. |

Abstract
Graphene-based nanomaterials are being investigated for their biocompatibility and bioactivity, as well as their ability to improve osteogenic differentiation. In this research, the base material, reduced graphene oxide (rGO) sheets, were decorated with hydroxyapatite and strontium (rGO / HAp-Sr) to induce osteogenic differentiation in adipose-derived mesenchymal stem cells. Different techniques were used to determine the properties of the nanocomposite such as diffraction analysis techniques (XRD) and transmission electron microscopy (to evaluate the size and morphology of HAp-Sr on rGO plates), FT-IR (to analyze the nanocomposite functional group), Raman spectroscopy (to investigate possible disorders in nanocomposite structure and number of layers), induced dual plasma emission spectroscopy (to assess atomic concentration of Ca and Sr), zeta potential(electrical potential of the nanocomposite) and MTT (nanocomposite cytotoxicity assessment) were used. The ossification potential of the synthesized nanocomposite was investigated and confirmed using the calcium deposition test in dipose-derived mesenchymal stem cells. According to the obtained results, osteogenic differentiation induction is possible using synthesized nanocomposites without the need for chemical inducers.

Abstract
Parvin E'tesami, a modernist and classical poet, despite her short life, left behind a fruitful and influential poems that were effective in promoting mental, intellectual, and cultural health, especially in the literary and artistic fields, as well as in preserving the social order and in the growth of the spiritual of Iranian society. If we leave aside the gender view and examine Parvin's poems from the perspective of poetic art, we can better understand the art of this concerned person who is in pain. According to human nature and, as a result, femininity sense, Parvin uses her poetic art more in the service of human teachings and illumination within man than her artistic expression. This article seeks to investigate the origins of the intellectual teachings and enlightened philosophy of this rare poetess. For this purpose, Parvin Etsami's poetry is analyzed and described, with the approach of comparative literature, from two perspectives: intra-cultural and extra-cultural, study culture and:
- Intra-cultural factors and elements that caused the birth and growth of Pravin’s thought and the formation and growth of his artistic personality; and also
- The extra-cultural elements and factors that led to the formation of the worldview and artistic attitude of the poet are discussed and investigated and its sources are explained.

Abstract
Hafez, le grand poète persan, utilise des allusions, des histoires et des récits dans ses poèmes. Le contenu de ses récits est la matière première et un plan d’expression pour transmettre des sens profonds qu'il utilise pour créer un concept important. En fait, en changeant l'allusion, Hafez fournit une analogie pour que les lecteurs n'interprètent pas sa poésie à son niveau littéral et superficiel. Pour ce faire, il choisit souvent ces analogies dans son époque même avant son temps qui sont communes entre l’énonciateur et l’énonciataire. L’objectif de cet article est de montrer que Hafez a créé un nouveau type de l’énonciation et du discours.
Cet article, en s’appuyant sur les théories sémiotiques, examine les vers narratifs de Hafez qui ont des propriétés élastiques et créent un espace cognitif condensé. L’histoire est implicitement et secrètement raconté. L'élasticité et de la condensation des énoncés en sémiotique est pour montrer les différentes dimensions qui dérivent du discours. Par exemple, l'élaboration ou le métalangage est le résultat de la largeur du discours, tandis que la nomination est le résultat de sa condensation. Les vers narratifs ont également cette dimension. À travers eux, le monde du passé et les événements historiques, diverses réalités significatives, sont représentées avec des éléments culturels. Le poète réduit la dimension du temps, reliant le passé au présent, et récite constamment des histoires du passé pour que l’énonciataire acquière une meilleure connaissance de lui-même et du monde

Abstract
In this study, the effect of number of stages on Tesla microvalve performance has been studied. To do this, different layouts including one to four-stage microvalves are investigated numerically. The main criterion is used for evaluation of valves performance is diodicity. Two-dimensional and steady state computations of the fluid flow have been utilized that reveal a strong dependence of diodicity on Reynolds number and the pressure drop. The results showed that for the same flow condition, the diodicity average of the two-stage microvalve is approximately 1.32 times of that of one-stage. Additional stages increase the complexity and they do not change the diodicity considerably. It is concluded that two-stage layout of Tesla type valve is the best option between the studied layouts. A two-stage layout of this valve in valveless micropump besides being compact, has the adaptability of the various functions. Also, the two-stage valve performance in three different sizes is compared with nozzle - diffuser type valve. Comparisons which are performed based on calculation of diodicity for applicable range of Reynolds numbers show that the diodicity is function of Reynolds number and is independent of the valve size. Also, the superiority of the Tesla type valve for higher Reynolds number and its weakness at lower Reynolds number are shown.

Abstract
A few species of aphids are widespread and economically important in Iran's apple orchards. In this study, we looked for economical, environmentally friendly, and efficient management of aphids with particular emphasis on green apple aphid (GAA) Aphis pomi (de Geer). We aimed to avoid early-season pesticide applications, avoiding specific applications for aphid control and managing them via applications done against codling moth (CM), Cydia pomonella L., choosing suitable insecticide and dose to minimize side effects on prevalent natural enemies. Thus, CM was monitored by pheromone traps from mid-March in an apple orchard of the Agricultural Research Station of the University of Tabriz to determine the time of application based on degree days accumulated from a biofix. The number of GAA, rosy apple aphid (RAA), Dysaphis plantaginea Passerini, and their natural enemies were counted separately. It is known that GAA is the predominant aphid, and two species of ladybirds, Coccinella septempunctata (L.), and Hippodamia variegata (Goeze), are dominant species of the region. Acetamiprid was chosen as an effective insecticide against both CM and aphids. The lethal effects of this compound were studied on different stages of H. variegata and the last instar GAA. The orchard was divided into four plots, and each plot was assigned to a treatment including control, label dose (LD), ½ LD, and ¼ LD. Although LD killed 10% more GAA than ¼ LD, the damage intensity was 12-16% higher in the former. Considering economic benefits and reducing side effects on natural enemies, we recommend using ¼ LD of acetamiprid.

Abstract
Molecular dynamics simulations have been performed to study the mechanical properties of hydrogen functionalized graphene. We find out that Young’s modulus and tensile strength of pristine graphene are in good agreement with experimental results. It is shown that hydrogen functionalization can considerably modify the mechanical properties of graphene. It is also found that the patterned orrandom hydrogen coverage have different effects on the mechanical properties of graphene. Using molecular dynamics simulation, we study the mechanical properties of hydrogen functionalized graphene under tension and shear deformations at constant room temperature. Young’s modulus and shear modulus, tensile and shear strengths and tensile and shear fracture strains are mechanical parameters that are calculated in order to investigate the mechanical properties of hydrogen functionalized graphene. Results show that in some cases, hydrogen coverage pattern is important independent of its coverage percentage. The underlying mechanisms were explained considering the difference between sp^2 and sp^3 hybridization.
