An important fact in the field of genre changes is that domination of one discourse and cultural current in a specific epoch has an undeniable effect on the appearance of a new genre. If some of literary criticizers have proposed the theory of literary genres basen on Darwin's theory and the natures of beings, we can interpret the theory of changes of literary genres based on Paul Tillich's views considering human's anxieties in the three domains of existence anxiety (death), moral and ethical anxiety (sin) and spiritual anxiety (absurdity and meaninglessness).In this paper, I will describe Paul Tillich's view in this domain and considering the domination of a thought discourse and the appearance of a specific mental type (anxiety) in a specific epoch,will try to analyze the appearance of a literary genre homogenous with that.

The first political story after the Islamic Revolution of Iran is probably Sellul-e hejdah by Darvishiyan. The work mirrors the author’s memories of the prison and ideological armed struggles. In addition, this text is the first story by the author after victory of the Islamic Revolution and can be considered as the first political story after the revolution. A study of the various levels of this story shows that Sellul-e hejdah, in spite of being a memoir, is one of the best examples of political fiction. The dominant radical discourse of the 80s [1360s] manifests the confrontation of four different generations.The first generation includes those conservatives who are traditional and religious and are unable to confront the dominant discourse.The second generation includes those conservatives who are not happy with the political decadence but prefer to maintain the situation.The third group relates to those radical freedom fighters that are not satisfied with the status quo and suffer from discrimination and tend to change the society.Finally, the fourth generation includes descendants of the revolutionaries who have little knowledge of the revolution and yet their lives are tied to it.

Tubular components, such as stepped tubes, conical tubes and box-shape tubes, are mainly produced by tube hydroforming process. Obtaining a sharp corner is the main goal in some of these components. In this paper, corner filling in stepped tubes is studied using a new multistage hydroforming die. The proposed die was simulated and filling of the die cavity was investigated. The finite element software, ABAQUS 6.4, has been used for simulation. In order to verify the simulation results, the new die of stepped tube was manufactured and then experiments have been performed on it. The results of the experiments verified the simulation results. It was shown that by using the new die, parts with sharp corners could be produced. The simplicity of the die and the low internal pressure are among the advantages of this die.Thickness distribution was also examined by FE simulation and via experiments and it is shown that a better distribution could be obtained by the proposed die set.

An experiment involving erosion simulation was conducted at the Soil and Water Con-servation Research Center of the University of Tehran. A split-factorial plot with four replications was designed. Five soil desurfacing treatments of blank, 5, 10, 15, and 20 cm of soil surface removal (E0, E5, E10, E15, and E20) were carried out, respectively. Fertilizer treatments were 0, 65, and 130 kg ha-1 of urea (equal to 0, 30, and 60 kg ha-1 of pure N) and 0, 107, and 214 kg ha-1 of triple super phosphate (equal to 0, 50, and 100 kg ha-1 of P2O5). Wheat (Triticum aestivum), Sardary cultivar, was cultivated in November 2001. To-tal precipitation was 223 mm during the growing season and 336 mm for the whole year (23 September 2001–22 September 2002). In order to reduce the effect of drought stress, three supplementary irrigations were applied during the growing season (13mm each). The crop was harvested in July and plant density recorded. Grain, dry matter and straw yields, as well as 1,000 grain weight were determined. The results showed that erosion had a significant effect (P<0.05) only on dry matter and straw yields. Each centimeter of soil surface removal, induced a reduction of 0.8% in dry matter. Phosphorus fertilizer had a significant effect (P<0.01) on yield parameters, relatively compensating the negative ef-fects of erosion. Nitrogen fertilizer did not show any significant effect on the determined parameters.

α-crystallin is a member of small heat shock protein family (sHSP) which shows both structural and chaperone functions. This protein plays important role in eye lens transparency and indicates protective function in the other tissues. The lenticular levels of copper ions significantly enhance in diabetic patients, aged and cataractous lenses. In eye lenses, the free copper ions induce ascorbic acid auto-oxidation, leading to formation of dehydroascorbic acid and other oxidative products as well as reactive oxygen species. The oxidized forms of ascorbic acid along with the reducing sugars enter into pathological reactions with the eye lens proteins, forming toxic advanced glycation end-products (AGEs). As one of the main components of eye lens antioxidant defense mechanism, glutathione could scavenge the copper ions, inhibiting the formation of reactive oxygen species in eye lenses.
In the current study, the structural and functional properties of human αB-crystallin were assessed using different spectroscopic methods. In the presence of copper ions, αB-crystallin exhibited important alterations in both structure and chaperone activity which upturned in the presence of glutathione. Moreover, incubation of human αB-crystallin with copper resulted in significant increase in the protein oligomeric size distribution which largely prevented upon simultaneous incubation with glutathione.
Overall, glutathione may scavenge free copper ions in the lenticular tissue, inhibiting their damaging effects on crystallin proteins and other redox-sensitive molecular targets such as ascorbic acid. Our results may introduce a new protective role for glutathione which is highly important in diabetic and aged lenses showing increased levels of copper ions.

Aims: The objective of this study was to compare growth parameters and phenol content of different safflower (Carthamus tinctorius) cultivars and one wild species of safflower (Carthamus oxyacantha) under urea fertilizer and vermicompost treatments, to distinguish can we use vermicompost instead of urea fertilizer.
Methods: The experiment was carried out under greenhouse conditions. A factorial randomized complete block design with seven replications was used. Experimental treatments were three vermicompost rate; three levels of nitrogen fertilizer; and three types of safflower.
Findings: The number of leaves, leaf area, fresh and dry biomass weights significantly increased with vermicompost application. Urea fertilizer only increased the plant height. The interaction between plant cultivars and vermicompost was significant for phenol content. All growth parameters of safflower except dry biomass weight were significantly different between cultivars. Conclusion: Wild safflower responded more than other cultivars to treatments so it can be used in plant breeding programs. Vermicompost treatment act better than urea fertilizer for growing of safflower, so it can be used instead of chemical fertilizer.

The objective of this study was to investigate dehydration kinetics of barberry (Berberis vulgaris L.) at different drying temperatures (60 ºC, 70 ºC, 80 ºC), air velocities (0.3 m s-1, 0.5 m s-1, 1 m s-1) with two types of pretreatment. Drying time and colour quality during dehydration were experimentally determined. Barberries were dried from the initial moisture content of 73.44% (w.b.) to the required moisture content of 18% (w.b.). Dehydration kinetics was monitored by measuring barberries weights at regular intervals. Convective drying curves were obtained for the treated and untreated barberries. The effect of two dipping pretreatments on drying kinetics of barberries was also studied. The two pretreatments were thermal shocking by immersing barberries in hot water, followed by cold water cooling, and dipping in olive oil and food grade K2CO3. Colour of the dried product was altered significantly during drying. The results indicated that the use of low temperatures is adequate for preserving this property. The air temperature significantly affected drying time and hunter colour indices of barberries (P< 0.05). With heat shocking and treatment with olive oil and K2CO3, drying time was reduced to about 40% and 60%, respectively. The total colour change (ΔE) and hue angle (H) increased with temperature. Moisture transfer from the test samples was described by applying the Fick’s diffusion model for calculating the effective diffusivity. The effective moisture diffusivity (Deff) of barberry increased as the drying air temperature increased. The Deff values were higher for the treated samples than the untreated ones. These values were also higher for the samples treated with olive oil and K2 CO3 emulsion than those treated with hot water. The effective diffusivity of the untreated and the pre-treated varied between 2.57×10-13 and 9.67×10-12 m2 s-1, respectively. Higher colour change was observed in barberries treated with olive oil and K2CO3 emulsion. Statistical analysis showed that temperature and pretreatment had the most significant effect on drying time at p<0.01.

Sour-orange (Citrus aurantium) seed oil was extracted by ultrasound-assisted, heat reflux, and Soxhlet extraction methods and their physical (melting point, viscosity, specific gravity, refractive index, and color) and chemical (acid value, acidity, peroxide value, iodine value, saponification value, and ester value) properties were investigated. Results showed although that some properties of the sour-orange seed oil such as acid value, acidity, peroxide value, iodine value, melting point, viscosity, and color were affected by the extraction method but its other properties such as saponification value, ester value, specific gravity, and refractive index were not affected by extraction method. In addition, the results of this study indicated that the sour- orange seed oil has some advantages such as low free fatty acid, low acid value, low peroxide value, low melting point, high saponification value, and high ester value. Therefore, the sour-orange seed oil can be introduced as suitable edible oil.

This study is conducted through a descriptive classification of interrogating defendants' spoken and written discourse in courts' conversations which has been designed based on ex post facto research. Research sample included 20 cases of criminal files gathered through available sampling method from the Archived Journals of Justice. McMenamin's (2002) Hierarchy Framework of Recognition Authenticity was used to examine stylistic and syntactic markers of defendants' spoken and written discourse. Stylistic and linguistic markers make a hierarchical model that is ranging from 1 to 9 levels. This model analyzed phonological, morphological, semantic, and syntactic clues that are unique among the defendants in the court files. The patterns concerned with that hierarchical model are resemblance, consistency, and population which are recruited to discover the criminals' spoken and written documents. The implications of this study showed that the use of this framework was successful in uncovering the criminals' identification for resemblance (50 percent), consistency (30 percent), and population (20 percent). Implications of the study suggest this framework may help the interrogators, judges, and attorneys to boost the efficacy of their profession.

1. Introduction
Forensic linguistics is an interdisciplinary field that deals with the scientific study of language in legal sciences. For reaching growth and dynamics, this discipline which is one of the sub-branches of applied linguistics needs the basics of theoretical linguistics in legal affairs. One of the main problems in the preparation of case documents is the analysis of the writing/speaking styles and structures of the defendants and proving their written and spoken authorship and identity in situations where it is difficult to verify and the suspects deny their handwriting or the recorded speech. In this case, forensic linguistics can help to check and prove the identity of the authors or speakers by comparing their previous and current speech and writing and using structural and stylistic markers. McMenamin (2002) proposed a hierarchical approach, which has three methods including resemblance, population, and consistency, and also several structural and stylistic discourse markers. Structural markers include grammar, use of vocabulary, the spelling of words, type of sentences, writing style (formal-informal), and so on. Phonetic markers include tone of voice, stress, repetition of words, accent, dialect, abbreviations, speaking style (formal-informal), silence, pause, ambiguity, etc. This research aims to reveal the effectiveness or ineffectiveness of the forensic linguistics approach in the classification of interrogating diagnoses through the analysis of structural and stylistic discourse markers in the speech and writing of suspects.
The research questions address McMenamin's approach to the article which is examining the documents and identifying defendants' written and spoken identities as follows:
1. To what extent does McMenamin's (2002) approach to identifying a hierarchy of defendants' written and spoken authenticity help in the recognition of the written and spoken authorship in courts?
2. What are the differences between the effect of resemblance, population, and consistency methods of identifying hierarchy on defendants' written and spoken authenticity recognition?
2. Background
In this article, descriptive analysis has been used to determine defendants' written and spoken authorship in forensic linguistics based on McMenamin's (2002) stylistic and structural approach. McMenamin listed three characteristics of stylistic-structural markers in language. The first one is the standard language or norm-referenced which is prescriptive. It means what the linguistic structures should be as standard norms. The second one is the change from the standard norms; however, the utterance is understandable. In other words, there is a change in the grammatical structure. The third one addresses the deviation from the standard norms and the utterance is rarely used in society or it belongs to a specific group or individuals.
Several scholars have used interrogations in legal courts and their relationship with language variations of speech/writing patterns of the defendants (Asiai & Noorbakhsh, 2014; Razovian & Jalili Doab, 2016; Najafi & Haghbin, 2019; Monsefi, 2012). Ainsworth (1993) examined the analysis of legal cases with linguistic descriptions and proposed the description of the language used by interrogators, suspects, and witnesses in the interrogation processes from the perspective of forensic linguistic domains. He has examined the way of language control and mentioned several points worthy of attention in this regard.
McMenamin (2002) focuses on the structures and styles of court discourse and classifies them into spoken and written discourse. Each discourse type includes variations of styles (speech/writing style) and structures (speech/writing grammar). These two are connected and form a continuum. McMenamin's hierarchical approach can be used to identify the markers that determine the defendants' spoken/written identity. In this approach, step-by-step determining the similarity or dissimilarity of the writings or statements of the suspect is matched with the writings or statements in their written or spoken records. This hierarchy starts from levels 1 to 3 (non-matching and definite identification) the person is removed from the list of suspects. This investigation continues from level 4 onwards until 9 (matching writing or speech and determining the identity of the accused). In this approach, intermediate levels (4 and 5) lead to information that the identification of suspected authors or speakers is done with 50% certainty and requires further investigation. Therefore, spoken/written documentation in the higher ranks leads to the identification of the identity of the suspect with almost certainty.
Innovation of the present study can be regarded as the gap in the research literature concerned with the lack of forensic research in identifying the authorship of the defendants with a scientific approach. Therefore, the present research has evaluated methods of resemblance, consistency, and population in identifying defendants via McMenamin's (2002) hierarchical identification approach. In these methods, the handwriting or audio files are matched with the previous records produced by suspects; and their degree of similarity or difference is checked from levels 1 to 9. Each level shows the degree of proximity of the suspect to determine the point of certainty.

3. Methodology
The current study examined twenty criminal cases such as signature forgery, text message/letter forgery, fake suicide letters, threatening text messages/letters, threatening audio/telephone files, or telephone harassment. The pool of data was gathered in the form of available samples from the archives of the Legal Journal of Justice between the years 2016 and 2021. These incidents happened in different provinces of Iran. To achieve a correct analysis of the writing style, all stylistic markers are identified in these texts. Then, the identification of the written and spoken identity of the defendants was investigated and analyzed based on McMenamin's (2002) framework with three analytical models of resemblance, population, and consistency.
The research method was a descriptive-analytical type, which analyzed the records of the cases in the past. Then, the identification of the written and spoken markers was analyzed based on McMenamin's (2002) approach with three analytical models' resemblance, consistency, and population.

4. Results and Conclusion
The results of the research showed that 80% of the investigated cases (i.e., 16 cases out of 20) carried out the principles of identity recognition based on McMenamin (2002). The framework was successful in recognizing the identity of the defendants. Moreover, findings showed that the use of this framework uncovered the criminals' identification for resemblance (50 percent), consistency (30 percent), and population (20 percent). Implications of the study suggest this framework is a help for interrogators, judges, and attorneys to boost the efficacy of their profession.
The investigation of the classification of verbal and written recognition of criminals showed that court experts or linguists were able to identify the spoken/written identity of criminals with high certainty. In McMenamin's hierarchical method, the similarity method took the highest percentage, because this method is one of the simplest methods to discover the comparison of phonetic and written markers. In the 20 investigated cases, there were more signature and text message forgery cases than the rest of the crimes

Bipolar plates are the most important and expensive components used in fuel cells. Metallic bipolar plates are the best choice to replace graphite or machined thick metal plates due to their lightweight and low cost. Selection of suitable forming process is one of the main subjects in fuel cell technology. Nowadays, hydroforming process is commonly used for the production of metallic bipolar plates because of its capability in forming light weight and complex parts. Among the various patterns of bipolar plates, serpentine flow field pattern inevitably brings two main defects of rupture of material during forming process and uneven flow distribution in practical operations. In this research, forming of a slotted interdigitated serpentine pattern on SS304 stainless steel sheet by hydroforming process has been examined using finite element simulation and experimental approach. The effects of process parameters and die geometry on the thickness distribution and filling percent are also studied. It is concluded that by increasing the forming pressure, filling percent of the die increases and the thickness of critical region is more reduced due to the increasing of drawing ratio. Also, it was found that hydroforming process has high repeatability.

Bipolar plates are the most important of fuel cells components. These plates are made with different methods such as machining, molding and forming and they are made of variety materials such as graphite, composite and metal plates. In this research, forming of metallic bipolar plates with pin-type pattern from stainless steel 304 with 0.11mm thickness is investigated numerically and experimentally using hydroforming process in convex die. In this regard, several parameters such as applied pressure, pin geometry, and depth to width ratio of the profiles has been changed and the experimental and simulation results of formed profiles, filling percent, thickness distribution and thinning percent of the formed parts have been compared. The results have been shown that no safe sample has been reached in depth to width ratio 1, while safe samples have been formed in depth to width ratio 0.67 in circle (a/b=1) and ellipse (a/b=0.7) samples and all samples in depth to width ratio 0.33 at 300 MPa pressure level in viewpoint of filling and thinning percentage. In general, increasing the small diameter to big diameter ratio (a/b) and decreasing the depth to width ratio (h/w) makes the thinning percent and filling percent more desirable.

Tube bending is used extensively in aerospace, automotive and other industries. Wrinkles in thin-walled tubes, changes in cross section and thickness changes during tube bending are the main problems in this process. Compressive force and internal pressure can be used to better control the bending process. If the bend radius to tube diameter ratio (R/D) in the bending process could be between 1 and 1.5, the bending is not done with conventional methods. Providing a new method that results in preventing both wrinkles and minimum tube wall thickness changes is important. In this paper, tubes producing with closed end. Since tube producing with closed end is difficult, in this study, initially closed end seamless tubes are produced by deep-drawing and ironing processes, thereafter tube bending process with ratio (R/D) equal to one was analyzed using experiments and simulations by hydrobending the new method. The pressure in which the tube takes the shape of the die completely without wrinkles, was obtained after investigating pressure changes. The effects of pressure changes on the thickness distribution of the tube inner radius and outer radius of the bent tube was also examined.

In this paper, with the aim of providing a new test pattern for empirical prediction of FLD of 304 stainless steel tube, firstly numerical investigation of hydro-bulging process with various load paths and die geometries has been performed on strain path and plastic instability. Study on geometry of dies has been performed by varying die corner radius (R) and bulging length (W). Here, effect of axial feeding on strain ratio (β) has been studied. In this condition, by increasing of W, strain ratio (β) tends to value of zero that this situation is independent to boundary condition. By increasing of die corner (R) in free loading condition, reduction of β occurs and the strain path approaches to plane strain state; while in loading with axial feeding condition, increasing of R has neglect able effect on strain path and ratio. In loading with axial feeding condition, increase in axial feeding strain ratio (β) is reduced drastically. From the simulated tests, number of 10 tests with distributed loading path on strain diagram was selected for empirical study. Meshed tubes are loaded controllably until tearing and the FLCs have been drawn using strains which were obtained near tearing locations.

Aluminum alloys have high strength to weight ratio and Poor formability at room temperature is the main drawback of using these alloys. In order to overcome this limitation, the work material is formed at higher temperature. One of the forming processes is hydrodynamic deep drawing on which no relevant research has been reported in warm condition. In the present paper, after examining the formability of 5052 aluminum alloy in warm hydrodynamic deep drawing, the effect of media pressure, temperature and forming speed on thickness distribution and punch force in forming of flat-bottom cylindrical cups was investigated. In order to perform a complete investigation, the simulation of the process was established using ABAQUS software. It was illustrated that the results was in accordance with the experimental findings. It was also demonstrated that increasing the maximum oil pressure to a specified level could improve the thickness distribution and lead to increasing the punch force. The required punch force was decreased with increase in temperature but remained unchanged by punch speed variation. The maximum thickness reduction was decreased with increasing and decreasing of temperature and punch speed, respectively. Moreover, the forming of the sheet at room temperature, isothermal and non-isothermal warm forming processes was compared. It was concluded that the maximum thickness reduction in the formed part was less in the cases of cold forming and non-isothermal warm forming than the isothermal warm forming. But the required forming force is decreased in isothermal warm forming when compared with the other two conditions.

This study attempts to numerically investigate the hydro-thermal characteristics of a ferrofluid (water and 4 vol% ) in a counter-current horizontal double pipe heat exchanger, which is exposed to a non-uniform transverse magnetic field with different intensities. The magnetic field is generated by an electric current going through a wire parallelly located close to the inner tube and between two pipes. The single phase model and the control volume technique have been used to study the flow. The effects of magnetic field has been added to momentum equation by applying C++ codes in Ansys Fluent 14. The results show that applying this kind of magnetic field causes to produce kelvin force perpendicular to the ferrofluid flow changing axial velocity profile and creating a pair of vortices leads to increase the Nusselt number, friction factor and pressure drop. Comparing the enhancement percentage of Nusselt number, friction factor and pressure drop demonstrate that the optimum value of magnetic number for Re_ff=50 is between Mn=1.33*10^6 and Mn=2.37*10^6 So applying non-uniform transverse magnetic field can control the flow of ferrofluid and improve heat transfer process of double pipe heat exchanger.
