The world is evolving every day, every hour. It does not stop for a moment, and the people of the world owe this rapid progress to communication. The main source of this communication and its important tool is language. French has always been considered by teachers as a widespread and effective language in the world, but structural difficulties, especially in the field of grammar, have created challenges in the process of teaching French. This study seeks to decipher the reasons behind the difficulty of teaching French grammar, especially adverbs, to non-French language learners (here, English and Persian). The present research study is based on a structural comparison of the three languages (French, English and Persian). In this study, the obvious differences between these three languages, especially Persian compared to the other two languages will be analyzed in the following sections of this study. In fact, these are conceptual differences that make it difficult to study a foreign language course, and the teaching course will be enjoyable by carefully examining these differences that are rooted in the culture of each country. In other words, the depth of language differences determines the severity of the difficulty of teaching French to non-French speakers.

Nowadays, the importance of communication and relationship with other countries is undeniable. Language plays a crucial role in the dissemination of science, awareness, knowledge and technology in a world where there are diverse languages, cultures and nationalities, but the need to learn a language has become essential due to the conceptual differences of languages. French has always been considered by teachers as a widespread and effective language in the world, but structural difficulties, especially in the field of grammar, have created challenges in the process of teaching French. This study seeks to decipher the reasons behind the difficulty of teaching French grammar, especially adverbs, to non-French language learners (here, English and Persian). The present research study is based on a structural comparison of the three languages (French, English and Persian). In this study, the obvious differences between these three languages, especially Persian compared to the other two languages will be analyzed in the following sections of this study.

The family is identified as an institution or social institution resulting from the marriage between men and women. One of the manifestations of human social life is the existence of a healthy and constructive interaction between human beings, love for one's kind and expression of communion and empathy for each other. The main pillar of family as the foundation of society is marriage. Marriage is one of the most important events in human life. Marriage is the most important and fundamental human relationship because it provides the structure for the creation of family relationships and the upbringing of the next generation. The aim of this study was to identify the dimensions of effective dialogue between couples using fuzzy Delphi technique, weighting and prioritization of each using gray analytic hierarchy process technique. For this purpose, first, by reviewing the theoretical foundations and background of the research, the dimensions of effective dialogue between couples were identified, then using the viewpoints of academic professors and 50 couples, they were randomly identified by fuzzy Delphi technique and questionnaire in five dimensions. The results of this study showed that communication skills dimension ranked first and dimensions of informed dialogue, planning for dialogue, talk, and optimism about the results of dialogue ranked second to fifth. The results of the present study can provide a comprehensive view to counselors and couples about recognizing the dimensions of sustainable conversation.

Optimization of energy generation in power plants and also taking into consideration the environmental pollutions are the most significant concerns in the field of energy. In this research, the main aim is that due to wasting a massive heat out of cooling towers of power plants, through a conceptual approach, this heat shall not be wasted as far as possible, and can get reused in the reheat cycle. As well, this approach might get used in the regenerative cycle of power plants to warm up the inlet fluid. Since in the reheat cycle of a power plant, vapor enters the boiler to be warmed up and then gets transferred to the low-pressure turbine (after passing through the high-pressure turbine), the heat poured out of the cooling tower can be transferred to the vapor before the high-pressure turbine. It causes the optimized usage of the heat poured out of the cooling tower, and makes the vapor temperature to rise, and causes its better drying and subsequently improvement of power plant efficiency and also stop making sediment and corrosion of turbine blades. Besides, applying this approach causes the energy not to be lost, and cuts the fuel costs, and environmental protection.

In the present study, the effect of electromagnetic field on the salt and water transport and reduction of carbonate deposit during reverse osmosis desalination was investigated. The electromagnetic field was generated by AC current through a solenoid wound around the membrane separation module. The current intensity and frequency was 25 A and 50 Hz, respectively. Experiments were conducted using CaCO3 solution at the concentration of 5. 5 mmol/L. For comparison purposes, desalination by the membrane, in the presence and absence of an electromagnetic field was conducted. While the desalination process temperature was kept constant, the product temperature increased by less than 2 ° C when the electromagnetic field was applied. The system performed sustainably when it was exposed to the electromagnetic field. During the experiments, salt rejection, permeate flow rate and membrane pressure drop were compared in the presence and absence of an electromagnetic field. Moreover, scanning electron microscopy (SEM) was used to investigate the morphology of the precipitates. It was found that the salt rejection and permeate flow rate increased when the electromagnetic field was applied. Furthermore, SEM analysis proved that CaCO3 precipitations formed in the presence of an electromagnetic field were in a powdery form with a lower density than the precipitation formed in case of not using electromagnetic field.

Supplier evaluation is one of the most important and fundamental measures in purchasing management in a supply chain and the reason is the key impact of the supplier on the cost, quality, timely arrival of the goods and the level of service provided when receiving the goods. Therefore, the competitive necessities related to cost efficiency make it clearer the necessity of joint utilization of collective capability in order to create new values for customers. The aim of this study was to prioritize the indicators of automotive parts suppliers. Price, quality of parts, timely delivery, Customer Satisfaction and after-sales service were identified for ranking after interview with automotive industry experts. The statistical population of the study is 25 senior experts of SAPCO Company that due to limited experts, the entire statistical population has been used. The technique used for weighting indicators and ranking using Fuzzy Analysis Network Process (FANP). The results of this study can be presented to experts and experts by identifying the effective indicators in selecting Iran Khodro suppliers in the existing competitive environment and help them to make decisions and make better decisions.
