The aim of this study is to investigate the fundamentals of Wittgenstein's theory of language games and its role in overcoming false preconceptions and biases. This qualitative research utilized a conceptual analysis and inductive method to review the related literature. In the findings section, by examining the theoretical foundations of Wittgenstein's linguistic games, we first critique the shortcomings of early philosophy such as the absoluteness of affairs, a purely analytical approach and ostensive definition, and then, the characteristics of language such as sociality, variability and discussion of its use and instrumental role were mentioned. Also, while expressing the mission of Wittgenstein's philosophy, the position and cause of the centrality of language in his philosophy was revealed and finally, due to the new perspectives on the theory of language games, and based on it, as well as Wittgenstein's way of working in later philosophy, a set of strategies was proposed to overcome biases. Overcoming the sense of essentialism, perspicuous representation, self-imposed exile, experiencing different occupations and professions, emphasis on differences, and eventually designing appropriate questions are among these strategies. As a result, it can be acknowledged that many false beliefs and preconceptions are passed on through language to future generations, and therefore many issues have survived throughout history. Therefore, incorrect concepts and ideas should be identified in the language and their repetition should be avoided by removing them.

The experience of time, like anything else in the world, can manifest itself in the text. Time is regarded as a structural element of the text. One characteristic of narrative is that time is considered as the main element of representation tool and the represented object. Therefore, time is described in the light of the chronological relationship between story and the representing text. By analyzing the time of the story and the time of the representing text, it can be concluded that in all the four plays of Naghmeh Samininarrative has two kinds of temporalities: the cyclic and the linear. The linear temporality gives a dramatic characteristic to the text, while the cyclic temporality gives an epic characteristic to the text. The cyclic temporality is always connected to a particular place and somehow reveals the feminine subjectivity governing the text. This study aims to show that when the linear temporality is dominant, the text is dramatic, and when the cyclic temporality is dominant, the text becomes narrative, while both temporalities exist in these four plays simultaneously.

Russian and Persian languages, regardless of the linguistic worlds, are special languages ​​in terms of phonetic system, grammar, vocabulary, etc. and have differences with each other Since the learners have already internalized the linguistic knowledge of the first language in their minds, they are very likely to commit errors in the process of learning a second language. This phenomenon, which is mostly natural and unavoidable, is referred to as interference. The present study aims to explore the effects of interference on the errors by providing evidence from the usual errors committed by the Persian-speaking learners of Russian in the elementary level. First, the authors  attempt to detect and classify the speaking errors of the learners in terms of the type of interference, and then the authors provide an analysis of them. Phonetic tests are used to collect the data. The participants of the study were 51 elementary level students in Isfahan, Guilan and Gonbad universities. The analysis of the data suggests that the target language (Russian), as one of the influential factors contributing to interference, has a drastic impact on the errors committed by the Persian-speaking learners of Russian.
 
1. Introduction
The present study examines the role of interference and its effect on the occurrence of such errors by referring to some common mistakes of Persian-speaking Russian learners of elementary level. The purpose of the present study is to investigate and identify the phonetic errors of Persian-speaking Russian learners, which are categorized and analyzed according to the type of interference, and the source of errors and the frequency of occurrence of each of them are specified separately. In this study, the authors seek to answer the following questions:
1. Do the language system and rules of the language being taught interfere with the corresponding rules in Persian?
 2. Which type of Mistakes are due to interlingual or intralingual errors made by Russian-learning students at the phonetic levels ?
 
2. Literature Review
The term "interference" was first adapted from physics by linguists. In linguistics, the subject of interference was first used in the second half of the nineteenth century, through which linguistic phenomena arising from the connection of one language with another were studied. The subject of interference has been discussed by many linguists and researchers, including Rosenzweig (1972), Weinrich (1972), Selinker (1974), Ziahosseiny (1999, 2009), Azimov and Shokin (2009), Choybonova (2009), Yar Mohammadi and Rashidi (2009), Barakhta (2015). Among the few studies that are somewhat close to the subject of the present study in the Russian language, the following works can be mentioned:
1. Elham Babaei Veleni (2013) in their dissertation "Comparative study of the phonetic system of Persian and Russian";
2. Gholami (2005) in a study entitled"On some common mistakes of Iranian language learners in Russian speech".
 
3. Innovation
In the last two decades, valuable and comprehensive studies in the Russian language - mostly based on areas such as Morphology, syntax, semantics, etc. - have been conducted by Iranian researchers, but no necessary and extensive  research has been done specifically and separately in the field of  Interference in the occurrence of phonetic errors of Persian-speaking Russian learners of the elementary level of the Russian language.
 
4. Methodology
The research method in the present article is based on the description and analysis of errors. The statistical population of this research consists of 51 students of the elementary level of the Russian language entering the universities of Isfahan, Guilan, and Gonbad-e Kavus in 1398. The instrument used to collect research data was the phonetic test.
 
5. Discussion and analysis
In this study, it was found that with the help of error analysis, it is possible to identify problematic cases in the field of phonology that Russian-learning students can potentially face with. In relation to phonetic interference, four categories of errors were identified: stress errors on the pronunciation of words, substitution of consonants and vowels, pronunciation of several consonants in a word, and finally errors related to the pronunciation of hard and soft consonants. The results showed that in terms of frequency of occurrence, the stress errors on the pronunciation of words has a significant share of errors, which indicates a significant difference compared to other errors in this area; in terms of the origin of the frequency of production, three categories of errors, the main cause of which is the influence of the Russian language on Persian, are more common than the error of pronouncing the sequence of two or more consonants in a word that has an interlingual origin. Therefore, based on the obtained results, it seems that phonetic interference has occurred as a result of the difference between the mother tongue (Persian) and second language (Russian) systems and, of course, the influence of the Persian phonetic system from Russian.
 
6. Conclusion
Overall, the results of the study confirm that in the process of learning Russian as a foreign language, the first language system (Persian), which is often imprinted in the minds of Russian students, does not play a significant role in errors and students often make the mistakes due to difficulty and lack of paying attention to the rules governing the language being taught. Based on the analysis of the types of errors studied and according to the results of this analysis, practical solutions can be provided to reduce the occurrence of errors in facilitating Russian language teaching for students. Description of errors can cause the teacher to pay more attention to solving problematic issues in order to advance the educational goals. It is recommended that the content related to the analyzed errors be included in the educational resources and appropriate exercises be included in the curriculum to minimize the amount of errors in language learners.

Accurate and nondestructive methods to determine individual leaf areas of plants are useful tools in physiological and agronomic research. A determination of the individual leaf area (LA) of such species in Brassicaceae family as red cabbage (Brassica oleracea var. cappitata L. f. Rabra), cabbage (Brassica oleracea var. cappitata L. F. Alba) and broccoli (Brassica oleracea var. Italica L.) involves measurements of leaf parameters including leaf length (L) and width (W), or some combination of these parameters. This research was carried out during 2008 (on eight cabbage, six broccoli, and three red cabbage genotypes) under open field conditions, to see whether an equation could be developed to estimate leaf area of cabbage and broccoli across their genotypes. Regression analysis of LA vs. L and W revealed several equations that could be used for estimating the area of individual cabbage and broccoli leaves. A linear equation having W as the independent variable provided the most accurate estimate of red cabbage as well as ordinary cabbage LA. The linear equation (LA= a+b W2) exhibited a high accuracy and precision in estimating red cabbage and non-red cabbage LA. For broccoli a linear equation having LW as the independent variable provided the most accurate estimate of LA, but required twice the time needed for leaf area measurement.

In this paper, a new forward extrusion process is proposed for producing large-diameter tubular components. At the beginning of the process, a round billet is located in the container and then extruded into a preliminary die with three bean-shaped holes forcing a hole in the original billet. The material is then entered into another die with a diverging and converging surfaces designed to weld the material and decrease the tube thickness. Material flow behavior, applied strain and the required process load were predicted using finite element (FE) simulations. The results showed that the new extrusion process had three important advantageous namely a lower process load and a container with a smaller diameter while applying much higher plastic strain compared to the conventional methods. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . .. . . . . . . . . .. . . .. . . . . . . .. . . . . . . .. . . . . . . . . . . . . . . . . . . .. . . . .. . . . . .. . . . . . . . . . . . . . . . . .

In recent years, rubber pad forming process have many advantages, such as high flexibility, good surface quality and lower manufacturing costs; RPF have been widely used in automotive, aerospace and military industries. In present research, numerical and experimental analysis of free bulging 304 stainless steel seamed tube, using a polyurethane elastic pad has been studied. Firstly, 3D simulation of seamed tube bulging using the finite element ABAQUS/Explicit 6.12 software by several frictional conditions has been performed. An incompressible hyperelastic pad has been modeled by Mooney-Rivlin constitutive equation and the elastic-plastic behavior as more as progressive ductile damage criterion FLD for steel tube were assumed. In the experimental activity, compression test of rubber was carried out according to ASTM D575-91 standard and compressive stress-strain curve and the Mooney-Rivlin constants were determined. Forming of meshed tubes by using elastic pad with different lubricating systems have been conducted up to onset of bursting in the seam weld and longitudinal, hoop and thickness strains were measured. Results showed that friction, especially between rubber and tube plays the main role in controlling wrinkles, increasing the bulge depth, reducing the forming load and friction dissipation energy of the process. Also observed that the intact parts without any wrinkles formed by using nylon lubricant between tube and rubber and drawing oil between tubes and die.

Bulging with elastomer tool has been used in the production of integrated hollow parts as one of flexible forming methods. Nowadays, most industries such as Aerospace and military are using flexible die forming methods due to their flexibility, high quality and lower cost. In this research, finite element simulation has been implemented by ABAQUS software to investigate the behavior of stainless steel 304 tube bulging process using elastomer tool. By comparing the geometry of deformed tubes in experimental tests and simulation results, the FEM model was verified. The aim of this study is to determine the process factors and their effects on the average thickness and depth of bulged tube. In this regard, design of experiment (DOE) was performed using a full factorial method and the results were interpreted using analysis of variance (ANOVA). Also a regression model was presented to predict these responses. Results showed that among the studied factors, friction (between tube and rubber), rubber height, punch displacement and tube axial feeding have significant effects on the process. Finally, the optimal values for significant factors were presented.

From oil and gas engineering point of view, one of the challenges in low permeable or damaged wells is improving the productivity. There are different methods to increase the productivity of low permeable wells and one of the most efficient one is hydraulic fracturing. In this study, two-dimensional modeling of hydraulic fracturing using finite element method and cohesive element approach through traction-separation law has been performed. This approach avoids the singularity in the crack tip and the cohesive zone fits naturally into the conventional finite element method. Hydraulic fracture is assumed to propagate in a poroelastic and permeable medium with a constant injection rate and under quasi-static conditions and the criterion for fracture initiation is quadratic nominal stress criterion. Also as a propagation criterion, Benzeggagh Kenane (BK) approach has been considered. Two types of elements have been implemented in the model which are 4-node bilinear displacement and pore pressure reduced integration and 6-node displacement and pore pressure two- dimensional cohesive element. Cohesive elements have three degrees of freedom that two of them are in X and Y directions and one of them is pore pressure. Mesh size in the near fracture region is small enough to consider the stress and pressure distribution efficiently and avoid any problem in convergence. Meantime, to decrease the computation cost the mesh size gradually increases from fracture area to the boundaries. Also, to increase the accuracy of the model, the time steps for fracture propagation is 0.01 second. In addition, the effect of fracturing fluid has been directly included in the model which means that the fluid pressure would be applied along the fracture without any simplifying assumption. To validate the model, the results have been compared with KGD approach. The results indicate that in the initial steps the pressure at the wellbore wall is high which decreases with time significantly and eventually it gets a steady and uniform trend. In other words, in the initial steps, the fluid pressure should be high enough to overcome the hoop stress around the wellbore and after some injection periods, the fracturing fluid pressure would reach the breakdown pressure and the fracture starts to initiate and propagate. It is clearly observed that increasing the injection rate would lead to faster propagation of hydraulic fracture and in the models with higher injection rate the fracture tends to grow in the propagation direction. This indirectly means that increasing the injection rate would affect both opening and length of the hydraulic fracture which can result in increasing the productivity. The results reveal that the peak of the normal effective stress profiles corresponds to the fracture tip position, where the fracture opening is zero,and the peak value equals the cohesive strength of the material,as expected.Moreover,with increasing thedistance from the fracture tip,the stress decreases rapidly and approaches the initial stress value. The way that Young’s modulus affects the overall characteristics of hydraulic fracture implies that higher Young’s modulus would lead to longer fractures. In other words, formations with higher Young’s modulus can be fractured easily but the opening of the hydraulic fracture would reduce at the same time. This also indirectly means that Young’s modulus would play an important role in the productivity.

Ultrafiltrated (UF)-white cheese is almost a new generation of white-cheeses that is produced throughout ultrafiltration process. This cheese has a soft and spreadable texture and is distributed in the market after a short storage period. Lactulose is a prebiotic compound that in addition to its positive effect on the growth of probiotic bacteria, its beneficial health effects on human well-being is proved. In the current research, synbiotic cheese samples were produced with the usage of demineralized ultrafiltrated whey powder (DUWP) at 3 levels of 0, 1 and 2%, lactulose at 2 levels of 0 and 1%, and bifidobacterium bifidum as probiotic bacteria. Experimental samples were analyzed and tested for physicochemical analysis including pH, acidity, moisture, syneresis, fat, protein and soluble nitrogen to total nitrogen ratio (TSN/TN) during 60 days of storage at 4 ◦C. Results revealed that addition of DUWP and lactulose, except for protein, had significant effects on the other tested parameters. In addition, the time of storage period had noticeable impact on all the examined physicochemical properties (P<0.01). Based on the results of this study, it was found that the best UF-white synbiotic cheese could be produced with the usage of 1% of each DUWP and lactulose powders.

During last decades, consumer awareness in importance of healthy intake has led their tendency towards the potential health benefits of particular foods and food ingredients. These conditions resulted in development of functional foods. In the current research, the effect of different concentrations of demineralized ultrafiltrated whey powder (DUWP) at levels of 0, 1 and 2% (W/V) and lactulose at levels of 0 and 1% (W/V) on symbiotic ultrafiltrated cheese were evaluated as a functional food. The color values, total acceptability and survival ability of Bifidobacterium bifidium during 60 days of storage at 4 °C were studied. Results showed that as the amount of lactulose and DUWP powders increased, the number of probiotics enhanced meaningfully, while the number of probiotic bacteria deceased with passing the storage time (p<0.001). However, the count of probiotic bacteria in samples containing lactulose and 1 or 2% DUWP at the end of 60 days of storage time were in the standard range of probiotic foods (>10⁷ Log cfu/g). The colorimetric results showed that as the amount of DUWP and the storage time increased, the lightness (L*) decreased significantly (p<0.001); but addition of both powders had no significant effect on a* and b* values. Based on the obtained results, the synbiotic cheese containing 1% DUWP and 1% lactulose powder as compare to control sample had a higher count of probiotic bacteria. Meanwhile, no differences in color quality and total acceptability were found between these two samples. Therefore, this synbiotic ultrafiltrated cheese was determined as the best functional cheese sample.

Nowadays, Functional food products as healthy diets have been considered extensively among consumers. Moreover, the use of particular microorganisms, for instance probiotic bacteria, offers probabilities to progress novel foods with appropriate shelf life. In the current research, in order to produce a functional ultrafiltrated (UF)-cheese, demineralized UF-whey powder (DUWP) at the levels of 0, 1 and 2%, and lactulose powder at the levels of 0 and 1% were used. Furthermore, bifidobacterium bifidum was used as probiotic bacteria. The textural characteristics in terms of hardness, cohesiveness, adhesiveness, springiness, gumminess and chewiness and sensorial propertis of the symbiotic cheese samples including odor, color, texture and taste were evaluated during 60 days of storage period at 4 ^◦C. Results showed that addition of DUWP and lactulose powders except for adhesiveness and springiness caused significant decrease in all textural parameters (P<0.001). Besides, except for adhesiveness and cohesiveness, the mean values of textural parameters usually enhanced up to middle of the storage time and thereafter decreased up to end of storage period (p<0.05). Sensory results revealed that although addition of both DUWP and lactulose powders resulted in lower sensory scores, no significant differences were found between control (without DUWP and lactulose) and sample containing 1% of each both mentioned powders (P>0.05). Therefore, based on the obtained results, sample having 1% of DUWP and 1% of lactulose determined as the best symbiotic UF-cheese sample. Since the potential contribution of this product in community health promotion and reduction of diseases risk, the production and consumption of this functional cheese is proposed.

The ECAP-Conform is one of the newest and less known processes that improve mechanical properties. In the present study, the effective parameters of the ECAP-Conform process for AA7075 have been investigated. Influence of parameters such as roller radius, bending angle, die channel angles, rod/roll friction coefficient, rod/die friction coefficient, and the aspect ratio of the die groove on the torque, the applied force on the die, the stress, and the effective plastic strain, the output rod curvature, and the strain distribution uniformity have been investigated. The design of experiments was carried out based on the response surface method by the Minitab software, and simulations were performed using the ABAQUS software. To validate the FEM, the ECAP-Conform process of AA7075 rod was performed and the comparison of experimental and numerical results have acceptable compliance (7.5% error). It was found that the die channel angles and the rod/die friction coefficient have a more significant effect on all responses. Moreover, to maximize the imposed strain and strength, and to minimize the process torque and curvature, as well as achieving a uniform distribution of strain, the optimal output parameters have been obtained.
