Abstract
The poetries of Sheevan Foumani are various from the conceptual and functional views.These stylistic varieties in poetries represent the frequency of experience that by means of them the poet incorporates component of meaning to the linguistic community of poetries.He carries out the aim by using the symbolic units in a specific style.Since the most of his poetries are symbolic and symbols of poetries are manifested in the forms of attributes,identification,personalization,impersonalization,the current research aims at investigating the semantic components of poetries of Fokhos and Aghadar in accordance with sociolinguistics. Also, it aims at drawing discursive boundaries through the symbolic representation of social actors based on the discursive functions.Therefore, two combined models of socio-semantic of Van Leeuwan and semio-semantic of Paris have been chosen to achieve these goals.As a main purpose,this research investigates the features of the model of Van Leeuwan on poetries.Consequently,the critical approach of the semio-semantic analysis of Paris tries to explain the discursive boundaries of poetries. Primarily by implementing the model of Van Leeuwan on verses, the results of research indicated that the representation of social actors in two poetries has been mostly formed by the factor of impersonalization. Moreover, based on the saliency of impersonalization, the semio-semantic analysis of poetries is formed by instrumenting this component in the direction of creating discursive spaces and the result indicated that discursive functions of appeasement,resistance,and insistence are often organized in textual layers that are related to the subcomponents of impersonalization.

Abstract
Sohrab Sepehri and Abbas Kiarostami are artists who could express their thought in the form of another language using the myths and symbols. The most important considerations in their works are neutral symbols. In this paper, the authors tried to review the symbolic nature using comparative approach and Gaston Bachelard's theory. We analyzed Hasht Keteb and Kiarostami's movies, and found that the mythical structure and contents briefly express differences and commonalities in their works. The most applicant natural symbols widely used in these works consist water, air, soil and plants. The results of our study showed that Water and soil, in various forms, involve a dual role in poetry and cinema: both as a symbol of death and resurrection, and creation. Wind is the symbol of divine origin and evolution. Also it indicates the death and destruction. Plant is the symbol of cosmic tree. Symbolic imagery and mythical nature, in Kiarostami's films and Sepehri's poems, can affect the poetic spirit of two artists, which is result of thier familiarity with Eastern mysticism and also for being influenced by painting and photography skills.

Abstract
Home Uterine Activity Monitoring (HUAM) has demonstrated to be of great value for preventing preterm labor in recent years. In this research, a low cost monitoring device for non-invasive monitoring of the uterine activity in pregnant women is presented. The new device has been designed based on an inductive Colpitz oscillator and vertical displacement of a ferrite core in a coil. The resulting frequency of the oscillator is proportional to the pressure in the external surface of the abdomen. This frequency is measured by the portable monitor. A low-power static random access memory (SRAM) provides long-term data storage. The proposed sensor for detecting uterine contractions has light weight, high stability and low cost. This sensor is very simple to manufacture and use for long-term ambulatory monitoring of the uterine activity. Furthermore, this sensor can be calibrated using software. Other features of the sensor are, resolution of 0.13 mmHg, repeatability close to 96% and input range from 0 to 95.32 mmHg.

Abstract
Studies in the field of learning and organization have changed through formation of the concept of a learning organization. As a result various models have been developed and customized for project based organizations. Still, they have not yet been customized for Project Based Organizations, as a very important category of organizations with growing importance. The special requirements of project based organizations in learning demands the development of a special model for project based learning organizations (PBLOs). This is routed in the temporary nature of projects. This study aims to develop a paradigmatic model for PBLOs based on case studies in two project based organizations of oil and gas industries. The strategy of the study is structured grounded theory and the data are acquired from interviewing 20 participants in the field of project and knowledge management. As a result of the interviews and by analysis and coding of 715 obtained phrases, 25 basic concepts were identified which have been placed in the paradigmatic model. Since a qualitative approach towards organizational learning has been very limited up till now, and in addition no studies have yet addressed PBLOs in particular, this work could be treated as a pioneering study in the field.

Abstract
The theory of quantity of money in that there exists a one-to-one relation between money growth and inflation, that means a highly and a continuous of rate of money growth leads to a high rate of inflation. During the recent years with the divergence of growth of money from inflation in the Iran economy leads to the opinion that an interruption has occurred between the growth of money and inflation. By the way, the main objective of this paper is to investigate the relationship between the growth of money and inflation by using the data of the 1350-2005 periods. The model that was used to investigate the relation of growth of money and inflation is a model that stemmed from quantity theory of money and is combining with the Phillips curve to model inflation to be linked trough expectations. The results revealed there exist a stable relationship between the growth of money and inflation and this states that in the long run one percent increase in the growth of money will increase inflation by 0.89 percent.

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
This paper gives a detailed analysis of direct torque control (DTC) strategy in a five-level drive and proposes a 24-sector switching table. The overvoltage problem due to high dv/dt is reduced compared to the 12-sector DTC. Using all vectors leads to better flexibility and reduces speed oscillations. Simulation and experimental results for a 3kVA prototype confirm the proposed solutions. A TMS320F2812 is used to implement the above strategy.

Abstract
Mango is a tropical crop that has been originated from south east areas of Asia. Mango has high decayed nature because it climacteric property. In order to investigate the effect of Putrescine and cold water treatments on post-harvest quality of mango, an experiment was done as factorial design in 2012. So local mango fruit was prepared at maturity stage, were treated with treatment combinations of Putrescine solution (0, 0.01, 0.1 mM) and cold distilled water (non-soaking and soaking for 30 and or 60 minutes). Quantitative and qualitative traits of fruit (like fresh and dry weight, length and width, firmness, total soluble solid, acidity, pH, taste and aroma, skin and pulp color) and also observation of rot symptoms have been measured. Results showed Putrescine and cold water treatments were affected fruit taste, acidity, and TSS/acidity ratio, also rot symptoms were reduced. Both concentrations of Putrescine affected the firmness and total soluble solids significantly. In all treatments combination of cold water and Putrescine fresh and dry weight was higher than control. The results indicated a positive and significant impact of mixed fruit dipping treatments in cold water and Putrescine in keeping appearance quality and improving storage life of mango fruit. Therefore the greatest concentration of Putrescine (0.1 mM) with immersion in cold water is recommended.

Abstract
The echoes obtained from ultrasonic testing of materials contain valuable information about the geometry and grain structure of the test specimen. These echoes can be modeled by Gaussian pulses in a model-based estimation process. For precise modeling of an echo, the parameters of the Gaussian pulse should be estimated as accurately as possible. There are a number of algorithms that can be used for this purpose. In this study, three different algorithms are used: Gauss-Newton (GN), particle swarm optimization (PSO), and genetic algorithm (GA). The pros and cons of each of these three algorithms are reviewed and by combining them, the benefits of each algorithm are used while its shortcomings are avoided. For signals containing multiple echoes, the minimum description length (MDL) principle is used to estimate the numbers of required Gaussian echoes followed by space alternating generalized expectation maximization (SAGE) technique to translate it to separate echoes and to estimate the parameters of each echo. The performance of the proposed algorithms for simulated and experimental signals with overlapping and non-overlapping echoes is evaluated and shows to be quite effective.

Abstract
Literary proper names can perform various functions. In fantasy literature, which usually has its own dedicated secondary world, these functions are even more prevalent. Analyzing the translation of these names provides new insights for translators of the genre and literary translators in general. In that light, the present study was designed to analyze the translation of proper names in five fantasy novels. To conduct the research, first the proper names in fantasy novels were identified and their functions were determined based on Gibka’s model (2018). Then by analyzing the translation of the proper names from English to Persian, the translation strategies were identified and examined. After the analysis of data, it became evident that contrary to popular belief, non-translation is not always the best strategy for translating literary names. Based on the results, the strategy of translation never caused the loss of semantic function in the translated texts, while in some cases the non-translation strategy caused the loss. Moreover, non-translation never caused the loss of localization function. Therefore, choosing the translation strategy for proper names with secondary functions in mind will help translators transfer these functions to the target text more effectively.

Introduction
Translation of proper names in fantasy literature can be a contentious topic among translators and theorists alike, since literary proper names can perform different functions within the narrative. The present research was conducted in order to determine the different functions of proper names in fantasy literature and the strategies employed for translating those names and to see if and how the translation strategy affects the proper name function in the target text.
Methodology
The present study was an empirical, descriptive and analytical research, conducted in order to analyze proper names and their translation in the fantasy genre. The corpus of this study was a parallel, bilingual one. It consisted of the novels, “Prince of Fools”, “The Liar's Key”, “Shadow and Bone”, “Everless”, and “Bone Season” and their Persian translations. These novels were translated to Persian within the last ten years (2014 – 2017) and could indicate recent trends in the translation of proper names in the fantasy genre in Iran.
The novels were wholly read with a purposive sampling method, and all of the proper names were extracted. Proper names were then classified using the eight relations and the twenty-two permanent secondary functions defined by Gibka (2018) which were applied to both the source text’s proper names and their translations in the target text. The data was analyzed at the lexical level. Each name along with the titles or other modifiers, were considered as one unit. Then, Van Coillie’s (2006) ten strategies for translating proper names were used as to analyze the translation of proper names.
Results and Discussion
In total 426 proper names were found and analyzed, out of which 214 had secondary functions. Among the proper names with secondary functions, the semantic function was the highest, followed by the localizing and sociological functions. Some of the proper names had two or three overlapping functions. Semantic and localizing were the two functions that overlapped the most (13 proper names), followed by localizing and sociological (11 proper names).
After the analysis, it became evident that most proper names’ functions stayed the same in the translation. All in all, no proper name changed its function in the process of translation and among proper names with no secondary functions, none gained new ones. However, there were cases in which the secondary function was lost or delayed in the process of translation.
Loss of function happened only for 11 semantic proper names and one localizing proper name, while no allusive and sociological proper name lost its function. The only translation strategy that caused the loss of function in semantic proper names was non-translation. Regarding the localizing proper name, phonetic adaptation was the strategy that caused the loss of function. Furthermore, delay of function happened for proper names with the semantic function and one proper name with the humorous function, and it only occurred when the proper name was transferred using the “non-translation plus additional explanation” strategy, where the additional strategy was in the form of a footnote or an endnote.
Conclusion
One of the important findings of this study was that while examining the translation strategies, some translation strategies were detected which had not been included in Van Coillie’s model (2006), namely combinations of different strategies, and in two cases, additional explanations added to a strategy other than non-translation (i.e. “replacement by a counterpart in the target language”, and “translation”). Furthermore, it did not relate the strategies to the secondary functions of literary proper names. However, the delay of function was the only issue that was not included in Gibka’s model (2018), which might be because this delay is probably specific to proper names in translated texts. Keeping this in mind, Gibka’s (2018) model can be effective for analyzing the translation of proper names in fantasy literature.
The results of this research can be useful for translation research and theory. This study showed that the “translation” strategy never caused the loss of the “semantic” function, while the “non-translation” strategy did cause this loss. So the “translation” strategy can potentially be an effective strategy for semantic proper names, while translator should be careful when using the “non-translation” strategy with semantic proper names, as the loss of function is likely to occur.
This can help translators who are working in the fantasy genre to gain a deeper understanding of the relationship between the secondary functions of proper names and the translation strategies. The results of this research can also benefit translation students in classes such as “literary translation”, since it indicates the significance of proper names and the attention that their translation requires, specifically in the fantasy genre.

Abstract
Cooling of high temperature systems such as gas turbine blades is one of the most important systems in industrial. In this paper, three dimensional cooling performance on a flat plate is calculated by a 3D finite-volume method and the realizable k-ε turbulence model which is the improved of the standard k-ε turbulence model and it can generate data more appropriate for fluid injections and jets. In this investigation, 4 different cases have compared together to find the best cooling case with maximum effectiveness. These cooling cases are including 2 cases of film cooling with console and cylindrical holes, one case of impingement cooling and one case of transpiration (with porous wall) cooling. For validation, the adiabatic cooling effectiveness for the console has been compared with the experimental data. These comparisons have been shown a good agreement between experimental and numerical data. The adiabatic cooling effectiveness, the effects of density ratio (by air and CO2 as a coolant) (DR) and blowing ratio (M) are studied in all cases. The adiabatic cooling effectiveness for console and transpiration cooling cases have compared together for studying the penetration of coolant fluid in the main stream (hot fluid) and showing the temperature and effectiveness distribution . The main purpose of this paper is finding the best cooling techniques with maximum effectiveness and the results have been shown which the designed transpiration cooling model has the best effectiveness respect to other cooling techniques.

Abstract
In recent decades, experimental studies of the vortex-induced vibration (VIV) became one of the interesting fields of science. However, variety of assumptions and methods of experiments have led to different results in various researches. Several parameters such as mass ratio, aspect ratio, degrees of freedom, and boundary conditions affect the VIV response of a simple circular cylinder. The current paper reports and discusses the results of in-water VIV experiments on an elastically mounted rigid cylinder with various types of end conditions. This paper focusses on the effects of the end condition by attaching an endplate to a circular cylinder and the results compared with those from a cylinder with no endplate. The Reynolds number ranges from 5.8×103 to 6.6×104. Experimental setup have also been compared and verified with some classical results of VIV. Results of current study was favorably compatible with previous researchers’ results.
The experimental results show that, the end condition noticeably changes the VIV amplitude especially in the lock-in area. Moreover, non-dimensional amplitudes shift to the higher reduced velocities when the endplate is removed. In the frequency responses, the cylinder with no endplate has lower quantities rather than the cylinder with an attached endplate. Evaluation of lift force coefficients also shows a similar pattern of effects on the non-dimensional amplitude. Consequently, the excitation of the structure in the lock-in region increases, when the endplate from the cylinder’s end is removed.

Abstract
The complex behavior of the aquifer system is studied by solving a set of governing equations using either analytical or numerical methods. Numerical techniques like finite difference method (FDM) is being used to solve differential equation in some simple cases. Recently Meshless methods are developed in engineering fields. They are used for solving differential equations in both simple and complex cases. As this methods needs no meshing or re-meshing on the domain the shortages of meshing disappeared. Less studies already performed in groundwater flow modeling with meshless method. In this study Meshless local Petrov-Galerkin with moving least squares approximation function and spline weight function is used to model groundwater flow in Birjand unconfined aquifer in steady condition. The computed surface of groundwater with meshless local Petrov-Galerkin method is compared with the results observation. The results are found satisfactory. The relative mean error and root mean square error of computed groundwater surface from Meshless Local Petrov-Galerkin are 0.0002 and 0.483 respectively.

Abstract
Green mold rot disease caused by Penicillium digitatum is the most economically important postharvest disease of lime fruit in all production areas. In this research, effects of essential oils (Cinnamomun verum, Eugenia caryophyllata, Thymus vulgaris, Zataria multiflora) for controlling green mold in Mexican lime (Citrus aurantifolia cv. Mexican lime) fruit were studied. Mexican limes were inoculated by Penicillium digitatum suspension and were immersed with the essential oils at three levels 0 (as control), 0.1 and 0.2% (v/v). Then, fruits were kept at 8±1oC and 90-95% relative humidity for 21 days. The results showed that the essential oils significantly affected fruit decay, weight loss, L*, a*, b*, total phenolic content and total antioxidant activity. After 21 days of storage, total phenolic content and total antioxidant activity of treated fruit with essential oils were higher compared with the control. In addition, essential oils were effective in decay and water loss control, and decreasing L* and b* compared with the control. The garden thyme essential oil at 0.2% decreased postharvest decay seven times lower than control but increased total phenolic compounds and antioxidant activity compared to the control 21 days after storage. Therefore, garden thyme essential oil has a strong effect on controlling green mold and maintaining quality of Mexican lime fruit.

Abstract
Nowadays, cities as a place of living and human activity are facing serious challenges in providing human needs. Increasing in population growth, vehicle ownership and communication development has led to complexity of the transportation system and its problems, including congestion, environmental pollution and the consumption of non-renewable resources. Therefore, changes in urban transport policies and efforts to develop and more use of the public transport, especially the bus, are one of the most important concerns in urban transport planning. A review of various studies suggests that planning for efficient use of bus infrastructures and enhancing the efficiency of public transportation operation in the world, require information on the infrastructure and passenger demand for lines and bus stations. Accordingly, it is necessary to carry out studies to predict passenger demand for bus stations in Tehran. Thus, this study predicts bus stations passenger demand for future short-term periods, using data gathered by AFC (Automated Fare Collection) and AVL (Automatic Vehicle Location). For this purpose, firstly AFC and AVL data was sorted according to the time for each bus line. Since passengers use their smart card while they are getting off the bus it means at the exit station thus identifying their origin station is vital, so that in second step, data of two data bases is compared and matched by writing computer code in Matlab software to determine the origin stations of passengers and then forming origin-destination demand matrix for each bus line in terms of its stations. This matrix is considered as the main data base of the study, a time series analysis, a seasonal autoregressive integrated moving average (SARIMA) and neural network as an artificial model are calibrated based on the available data. Both models’ goodness of fit indices are compared in terms of learning and generalization capabilities. For this purpose, initial data is divided into two subsets called learning and test data sets and comparison indices are computed for both aforementioned sets. The models’ results show that the multi-layer perceptron neural network model in terms of goodness of fit indices in both learning and generalization capabilities in prediction of bus station passenger demand is better than SARIMA model; however, the manner of influencing different factors such as day of week or month of year in passenger demand in each station is more clear in time series analysis. The passenger demand for each stations in first month in spring is different from the rest months in this season. Months in summer is also show different trends for passenger demand, while all months in fall and the first two months in winter have similar passenger demand in various stations. Official holidays has also significant influence on passenger demand so that reduce passenger demand by approximately 256 persons on average. All days in week have meaningful effects on passenger demand in comparison with Friday so that Monday and Thursday have the highest and the lowest effect on weekday passenger demand in bus stations in comparison with Friday, respectively. This analysis comparison show that if the precision of future prediction is important then neural network outweigh time series regression, while the identification of influential variables on passenger demand is better done by time series analysis.

Abstract
Coating the fruits using edible gums increases the appearance quality, improves the color and reduces their shrinkage at the end of the drying process. The purpose of this study was to investigate the effect of coating with wild sage seed, basil seed and xanthan gums on the appearance characteristics of dried quince slices in the infrared system. In this study, quince slices with a thickness of 0.5 cm were coated using wild sage seed, basil seed and xanthan gums (concentration of 1%) and then placed in an infrared dryer and the effects of radiation power (250 and 375 W) on the appearance characteristics were examined. Also, for modeling the color change index, the Power, Quadratic, Gompertz, Logistic, Richards, MMF, and Weibull models were used. Color indexes including lightness, redness, yellowness and color changes as well as changes in the samples area during drying time were examined. The calculated lightness index for the drying process of quince samples showed that the coated samples with wild sage seed gum were brighter. In terms of color change index, coated quince slices with wild sage seed gum showed the lowest color changes during drying time and the average values of this index for the uncoated sample, coated with wild sage seed, basil seed and xanthan gums were equal to 35.09, 20.20, 43.40 and 28.33, respectively (250 W). For modeling the color change index, the MMF model had less error than the others models. The results showed that the coating with wild sage seed gum maintained the appearance of the dried product and also the least shrinkage in the drying duration and at different radiation powers were observed in these coated samples.

Abstract
In this study, biodegradable packaging based on gelatin biopolymer (at a concentration of 3% w/w) containing nanoparticles of titanium dioxide (at a concentration of 1% w/w) and saffron extract (at a concentration of 2% v) by evaporation method was synthesized. In this study, physical properties (thickness, transparency, moisture content, solubility and water vapor permeability), mechanical, antimicrobial and antioxidant properties, structural and transparency properties of films were investigated. After analyzing the data, the results showed that the effect of saffron extract and titanium dioxide nanoparticles on all the studied properties was significant (P <0.05). Addition of titanium dioxide nanoparticles and saffron extract increased the thickness, improved the mechanical properties and reduced the moisture content, water vapor permeability, transparency, and solubility. Also, nanocomposite films containing titanium dioxide nanoparticles and saffron extract showed antioxidant properties (% 80%) and acceptable antimicrobial effects, especially against gram-positive Staphylococcus aureus bacteria. According to the results of this study, this type of packaging can be suggested as a suitable alternative to synthetic packaging.
