Abstract
Although critical pedagogy (CP) is a worthwhile approach to education, not much attention has been paid to its application in online courses. Acknowledging its pivotal role, this study intended to investigate Iranian EFL teachers’ awareness of CP and explore the possible effects of teaching experience on their awareness of CP via a CP questionnaire and a semi-structured interview. Furthermore, to evaluate teachers’ actual classroom application of CP, online EFL classes were observed. The results indicated that teachers’ awareness of the significance of CP principles did not help them fully implement the principles in their online teaching practices. A significant relationship between teaching experience and some subscales of CP principles was also found. The findings of this study can offer some implications for English teachers in the post-method era to rethink their previous critical views towards English language teaching and their roles as facilitators.

Abstract
This study employed a comprehensive scientometric analysis of scientific publications within the Journal of Language Related Research from 2012 to 2023, encompassing 871 journal documents. Utilizing VOSviewer software, quantitative tools were applied to analyze research output, authorship, collaboration patterns, thematic trends (past, present, and future), and geographical distribution. The analysis revealed a significant increase in the number of publications in recent years, though citation rates displayed variation across the timeframe. Visualizations based on co-authorship, bibliometric coupling, and citation data unveiled a dense network of collaboration among authors. The authors with the highest number of publications were Golfam (n =17) and Pishghadam (n =16), while Derakhshan (78) and Shakki (65) were the two authors with the most citations. Analysis of "authors' keywords" and "keywords plus" co-occurrences within the network pinpointed prominent thematic areas within the journal's knowledge domain and context, including "Persian language," "critical discourse analysis," "semiotics," and "cognitive linguistics." The study concludes with a discussion of the findings and their broader implications.

Abstract
Aim and Introduction
In most world economies, governments have been proposed as a complementary institution and are bound to interfere in the economy. The degree of government involvement in any economy depends on the political and economic system in that country. One of the government's intervention tools is subsidy payments considered as financial aids aiming at transferring government resources to buyers and sellers. Therefore, one of the most well-known ways of transferring income to vulnerable groups is subsidy payment. This tool has a long history in different economies. In general, subsidies can be divided into four categories: a) based on the government's goals, which include economic subsidies, development subsidies, social subsidies, political subsidies, and cultural subsidies; b) Based on the stages of the goods, which include consumption subsidies, production subsidies, distribution subsidies, service subsidies, export subsidies, and import reduction subsidies and currency savings; c) Based on the classification of the subsidy itself, which includes direct subsidy and indirect subsidy; and d) based on the reflection of its costs, which includes hidden subsidies and open subsidies. Also, regarding the methods of applying subsidies, it should be noted that subsidies in the consumption sector are mainly paid in cash, goods, general prices and coupons. On the other hand, the payment of subsidy will disrupt the price system and lead to deviation in production and investment.
Since governments dependent heavily on oil revenues usually seek to pay subsidies in general, they normally encounter many problems including waste of resources, increase in consumption, smuggling, lack of efficient allocation of resources and reduction of efficiency in the economy. This happens because the price of subsidized goods is not realistic. For this purpose, Iran and other developing economies are seeking to apply the policy of targeting subsidies. One of the results of policies targeting subsidies is the realization of prices, which will improve the performance of producers and choose an optimal production process.
Since targeting subsidies has significant effects on the relative advantage of manufactured goods and subsequent sustainable growth and development, therefore, it is crucially important and essential to investigate the effects of this policy on the business model.
A review of the experimental studies conducted inside the country indicates that the effect of reducing (eliminating) the subsidy of basic goods (Sections 25-22 in the software package of the Global Trade Analysis Project) on the trade pattern has not been investigated so far.
In this regard, the aim of the current research is to investigate the effects of reducing (eliminating) subsidies for basic goods (sections 22-25 in the software package of the Global Trade Analysis Project) on Iran's trade using the GTAP model.
Methodology
The Global Trade Analysis Project model is one of the types of Computable General Equilibrium (CGE) models, the software related to it (GEMPACK, RunGTAP) and the database are provided to the researchers by its designers.
In the current research, the data has been gathered in the form of four sectors (dairy, rice, sugar and other foods) and two regions (Iran and other parts of the world) and the analysis has been done in two scenarios which are designed as follows:
1) 50% reduction in the subsidy paid to the firm's consumption-domestic goods.
2) 100% reduction in the subsidy paid to the firm's consumption-domestic goods.
Findings
The results showed that in both scenarios, the economic welfare of Iran and the rest of the world decreased and increased, respectively, and the intensity of these changes is greater in the second scenario (removal of basic commodity subsidies). The share of resource allocation efficiency and term of trade and savings-investment relationship in reducing economic welfare is higher in the second scenario. The highest decrease in economic welfare in the first and second scenario is related to sector 25 and the lowest decrease in economic well-being in both scenarios is related to sector 22.
Reducing the subsidy paid on the firm's consumption-domestic goods in these sectors will increase the export of these goods. The most positive changes in Iran's trade balance in the first scenario (50% reduction in subsidies) are related to sector 25 and equal to 48.4 million dollars, and the most negative trade balance of Iran in the second scenario (complete elimination of subsidies) is related to sector 25 and equal to 7.96 has been negative. In total, the reduction of subsidies for basic goods simultaneously in all 4 sectors has led to positive changes in Iran's trade balance.
Discussion and Conclusion
According to the economic results of this research, it is recommended to gradually remove the subsidy paid to the firm's consumption domestic goods so that, while having a positive effect on the changes in Iran's trade balance, the economic welfare does not face a large and one-time decline

Abstract
Forming urban heat islands is a serious challenge of the present age and a concern of academic communities. Attention to this issue has increased tremendously in scientific articles and researches, particularly in the last decade. With regard to the importance of the issue, the aim of this study is to form a systematic review and thematic analysis of articles and other researches in this field. Moreover, the content of the key articles was analyzed and the most important factors affecting the formation of urban heat islands were represented in a diagram and each of them was analyzed separately. As examined, urban heat islands are affected by climatic and urban construction factors. The climatic factors include sunlight, wind speed and direction, cloud cover, soil moisture, air humidity, precipitation, latitude, seasonal topographic variations, and the proximity to the river and the sea. Although these factors are almost uncontrollable in the existing cities, they have enormous importance for deciding new towns location and making the decision for city development direction. The second group of factors mainly related to the design of cities is controllable. Among these factors, the most important one is the amount and quality of vegetation in the city. Other factors such as land use, urban density, type of materials used on the facade of the buildings and streets, form and geometry of the city, and also transportation mode could influence the intensity and extent of urban heat islands.

Abstract
In recent years, the increasing presence of antibiotics particularly ciprofloxacin (CIP) in aquatic environments has raised serious environmental and health concerns. This study investigated the efficiency of titanium dioxide (TiO₂) nanoparticles activated by ultraviolet (UV) light in removing ciprofloxacin from aqueous solutions. Experimental design was carried out using Design Expert software, and the effects of variables such as pH, reaction time, and initial drug concentration were evaluated. The results showed that increasing reaction time and decreasing initial concentration significantly improved the removal efficiency. The optimal pH range for maximum removal was found to be between 5 and 7. Additionally, the photocatalytic system used in this study demonstrated high performance, low energy consumption, and the ability to degrade the pollutant without the need for additional chemicals. These findings suggest that TiO₂-based photocatalysis is an efficient and environmentally friendly method for treating wastewater containing antibiotics.

Abstract
One of Hakim Sabzevari's arguments on the reasoner and reasonable union of "matter and form" is the argument, in which he considers the ontological principles of matter, form, and soul on the one hand, and on the other hand, he has put the view of Sadra's psychology as the basis for the completion of this argument. In order to distort all the arguments of Hakim Sabzevari, a published article accusing Hakim of "gross confusion" in recognizing the basic contents of philosophy. In this regard, in refuting the argument of matter and form, that article has turned to two major accusations. On the one hand, Hakim has been accused of using allegorical syllogism instead of argumentative syllogism, and on the other hand, it has condemned Hakim for the objection of confiscation. The analysis shows that this argument is based on total unity and that article has been distorted both in terms of reporting and in judgment, it has deviated to adopt illogical positions.

Abstract
Acknowledging the strengths of the national curriculum, the present study aimed at evaluating its approach towards foreign language education from three perspectives: (1) analyzing the foreign language section of the national curriculum based on the methodological and theoretical underpinnings, and its internal consistency; (2) examining its content based on the basic assumptions mentioned in the literature for setting foreign language policies and (3) evaluating its content based on the macro-documents of the country. In so doing, first, the relevant sections of the national curriculum were analyzed. The results indicated that, although the foreign language section of the national curriculum has some strengths such as a move toward decentralization and increase in hours of instruction, it suffers from some weaknesses such as vagueness of the content and lack of consistency and connection among the aims of the instruction. In order to examine the document from the second perspective, 6 criteria that foreign language education policies should follow were extracted from the relevant literature, and the document was evaluated based on these criteria. The results indicated both consistencies and inconsistencies between the content of the document with these principles. The national curriculum, then, was evaluated to find its matches and mismatches with the policies and orientations of macro-documents. The results indicated that the foreign language section of the national curriculum cannot set the ground for achieving the goals proposed in the macro-documents of the country. Finally, the paper offers some guidelines for developing national English language curriculum.

Abstract
The attitude or behavior, which is not based on logical actions- and cause and effect relations, has irrational origins; it happens due to a person's fear, threat, habits, and the unknown factors which he she believes to prevent the unbecoming events, called “superstition”. An increase in the literacy level and the popular culture in the society leads to a decrease in superstitious beliefs. It must be acknowledged that even modern people cannot reject superstitions, or get rid of them actually. This study has examined the causes of these prevalent beliefs and the way people apply them, via content analysis. Although the prevalence of superstition origins is established on irrational bases, people have applied them to gain benefit by impelling and propagating the folklore, preventing harm by inhibition, alleviation, turning the evil (scapegoat), and empathy.

Abstract
In his Notebooks (1914-1916), Wittgenstein announces that ‘artwork is the object seen sub specie aeternitatis’. At nearly the same time, in another part of the world, there was a critic and thinker, who thought art as making objects ‘unfamiliar’. He was Victor Shklovsky. I argue that there is a noticeable and yet unintended similarity and relation between these two aesthetic viewpoints. Wittgenstein and Shklovsky’s emphasis on art is its power to pave the way for the readers (in the extended sense of meaning) to feel things in themselves and ‘out of their normal context’. As Shklovsky claims ‘art removes objects from the automatism of perception in several ways’; in contrast, through ordinary way of seeing, objects are ‘reckoned as nothing’. According to Wittgenstein and similar to Shklovsky’s attitude ‘aesthetically the miracle is that the world exists. That what exists does exist’. In this paper I attempt to show that the early Wittgenstein’s ideas of aesthetics are in harmony with the Shklovsky’s formalistic theory of art. In this direction, I focus on Wittgenstein’s sub specie aeternitatis’ and Shklovsky’s defamiliarization; because I think that they fill each other’s gaps. An artist defamiliarizes objects and the spectators see the objects sub specie aeternitatis. In Shklovsky’s thinking Habitualization (which ‘devours works, clothes, furniture, one’s wife and the fear of war’) is very near to what Wittgenstein means by ‘the usual way of looking at things’.

Abstract
In this study, the three phase mixed matrix membranes comprising Pebax®1657, PEG-200 and MIL-53(AL) nanoparticles were evaluated for CO2 gas separation. The effect of various PEG-200 and MIL-53(AL) concentration within the pebax polymeric matrix on the structure, gas permeability, and selectivity of the membranes was investigated. To study the cross-sectional morphology, crystallinity and thermal properties of the synthesized membranes, scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were utilized, respectively. Fourier transform infrared (FT-IR), was also carried out to identify the formation of the chemical bonds in the membrane. SEM images demonstrated a uniform cross-section and admissible dispersion of nanoparticles. The results of the thermal analyses indicated an increase in crystallinity and Tg in presence of MIL-53 particles. Permeation of pure gases (i.e., CO2, CH4) through the prepared neat Pebax®1657, the blended Pebax/PEG-200 and the Pebax/PEG-200/MIL-53(AL) mixed matrix membrane was measured at the pressure of 2–10 bar and temperature of 30 °C. The results showed that at the pressure 10 bar, the CO2 gas permeation from 133.36 barrer in pure membrane increased to 311.7 barrer (134%) in a membrane containing 10%wt MIL-53.

Abstract
Background: Emergence of drug-resistant bacteria has highlighted the need to identify new and more efficient antibacterial agents. The aims of this study were to evaluate the antibacterial activity of dill (Anethum graveolens) seeds essential oil and to investigate the effect of cumin (Cuminum cyminum) seeds alcoholic extract on biofilm formation ability of Klebsiella pneumoniae.
Materials and methods: This experimental study was carried out at the Faculty of Medicine of Kurdistan University of Medical Sciences in 2014. Activity of dill seeds essential oil was evaluated based on the inhibition zone diameter and minimum inhibitory concentration (MIC) against some important pathogenic bacteria including: Vibrio cholerae, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Furthermore, the effect of sub-inhibitory concentrations of cumin seeds alcoholic extract was evaluated on biofilm formation ability of K. pneumoniae. The biofilms were formed on semi-glass lamellas and observed by a scanning electron microscope.
Results: Dill essential oil showed a good to moderate activity against the tested strains. The highest antibacterial activity was observed against S. aureus (inhibition zone of 15 mm and MIC of 0.62 mg.mL-1) and V. cholerae (inhibition zone of 14 mm and MIC of 0.7 mg..mL-1). The cumin alcoholic extract had no effect on biofilm formation ability of K. pneumoniae.
Conclusion: The results of this study showed the presence of antimicrobial compounds in dill extract. The cumin alcoholic extract was not able to inhibit biofilm formation ability of K. pneumoniae. Because of the medicinal plants properties, it is valuable to search for promising herbs and novel chemical compounds.

Abstract
Research subject: Selectivity and permeability are the major parameters of polymeric membranes in gas separation process. Hence, nowadays in order to improve aforementioned parameters, modification and enhancement issues for such membrane have been highly noticed.
Research approach: In this study, in order to improve the performance of polymeric membranes, the two-component blend membranes containing Pebax®1657 and PVA were synthesized for CO2 separation. The effect of different PVA concentrations within the Pebax matrix on structure, morphology and gas separation properties of resultant membranes was investigated. The chemical bonds, crystallinity and cross-sectional morphology studied through, Fourier transform infrared (FTIR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), and were utilized.
Main results: The results of the thermal analysis indicated an increase in crystallinity and also glass transition temperature in presence of 5 – 15 wt.% PVA, while the membrane crystallinity decreased by increasing the PVA content up to 20 wt.%. FESEM images demonstrated a uniform cross-section without any cracks and defects for neat Pebax membrane but by adding PVA to Pebax matrix, appeared cracks and cave structures on the cross- section of blend membranes. The CO2/CH4 separation performance of membranes was measured using a constant volume set up at 30°C and feed pressure of 2, 6 and 10 bar. The obtained results revealed that the CO2 permeability in blend membranes improved as the PVA content increased within the membrane. The best obtained CO2 permeability was 204.64 Barrer which gained by Pebax/PVA (20wt.%) at feed pressure of 10 bar. Moreover, the highest selectivity of CO2/N2 for blend membrane with 15 wt.% of PVA was about 100.21 at 10 bar and 30°C.

Abstract
One philosophical theme often attributed to Khayyámic rubáis is nihilism, which unfortunately has not been examined in detail and according to a firm theoretical basis. This paper probes into the theme in two famous Persian collections of such rubáis: Sadeq Hedayat’s edition of Taraneh-haye Khayyám as well as Forughi and Ghani’s Rubáiyát of Omar Khayyám. For this purpose, the paper consists of an introduction as well as two main parts and a conclusion. In the introduction, the necessity of holding the theory of Khayyámic rubáis —that is, a school of rubái-composing after Omar Khayyam and not the Rubáiyát of Khayyam— is explained. In the first part of the paper, which is entirely theoretical, based on Donald Crosby’s classification of nihilisms in his book, The Specter of the Absurd, two relating types of nihilism along with some common arguments for nihilism are mentioned. In the second practical part, the aforementioned definitions and assumptions are applied to the rubáis under discussion. At the end comes the conclusion.

Abstract
Farhang–e Bozorg-e Sokhan (Sokhan’s Grand Dictionary, 8 vol., under the supervision of Hasan Anvari, Sokhan, Tehran, 2002) is relatively a new research in the field of Persian Lexicography. This dictionary as using of the achievements of previous dictionaries has many outstanding innovations various aspects of Lexicography. For example, beside of using of body language, in the process of choosing of words, it has given attention to different aspects of transcription, combinations of words, examples and relevant evidences. Etymology of Persian words is one of the characteristics of this dictionary, especially for the first time, it mentions the Russian origins of 90 Persian words. However, despite of this innovation, we can see some defects and mistakes in the etymology and semantics of Russian loanwords in Persian language; the subject that we will study in this paper. In other words, here we try to answer this main question: “In the Farhang-e Bozorg-e Sokhan, to what extent the Russian loanwords in Persian language has been mentioned correctly and what is their difference with their origins in Russian from the viewpoints of etymology and semantics.
