Global expectations for strengthening the economic conditions of local communities are expanding. One of the pillars of strengthening this approach is the use of environmental and human capacities in rural areas, especially in the development of tourism. The above trends are proof of benefiting from the capabilities of income-generating resources and local advantages. Potential tourism centers are centers that have a high chance of attracting financial capital. In this regard, one of the tourist centers that has attracted attention in Iran is the Vashi Gorge. As a result, there are rural settlements on the way to this tourist destination, among which Jalizjand village is in direct connection with Vashi Gorge. Considering the proximity of the village to the mentioned territory and its possible effects on the village's economy, the role of the tourist destination of Vashi Gorge on the stability of Jalizjand village's economy is the aim of the research. The research method is descriptive-analytical, and its statistical population includes ten percent of the participants living in Jalizjand village. A simple random method was used for sampling. Based on the review of the theoretical research literature, six components of vulnerability reduction, diversification, poverty alleviation, environmental compatibility, efficiency, and productivity were selected as criteria for measuring the level of economic development of the village. The techniques and tools for collecting data and information were library, field, questioning, and questionnaire, respectively. One-sample and Friedman statistical tests were also used for data analysis. The results of the research prove that the Vashi Gorge tourism river has not been able to provide the economic stability of Jalizjand village. Because among the effective criteria, the four criteria of poverty alleviation, adaptation to the environment, vulnerability reduction, and productivity are at a medium to very low level of sustainability.

Villages have traditionally been identified and sustained with agricultural activities and have become the source of capital production. A type of capital whose role has been neglected in rural development is the accumulation of financial capital produced from the agricultural sector of villages and transferred to urban areas in various ways and forms and spent there. The withdrawal of income from the production of agricultural products reduces cash for investment in agriculture and the rural economy. At the same time, it can be the basis for increasing agricultural productivity and creating a platform for improving rural development indicators. In Dehgolan county in Kurdistan province, a kind of capital outflow from villages to big cities has formed, along with other factors, has caused the economic instability of villages. Despite the high income, adequate financial capital, and rich resources, these villages have not been able to use this opportunity to improve their development indicators, and the incomes from work and agricultural production are transferred out of the village economy cycle and transferred to the cities. The present research has analyzed the causes and factors of capital outflow from the villages to the cities and its effects and consequences on the local economy in the villages of Dehgolan county.

This research is descriptive-analytical research in terms of practical purpose and in terms of method. The methodological approach of the research is based on the comparative method. The statistical population of this research is 105 villages of Dehgolan county, which are located in five districts. The sample community is 15 villages selected using the stratified probability sampling method. The investigated samples were determined at the level of all villages based on the multi-stage cluster method with proportional assignment method from the respondents, and 340 farmer households (out of 2997 households in the sample villages) were considered the sample size based on Cochran's formula. The necessary data were obtained using a researcher-made questionnaire. Experts approved the content and face validity of the questionnaire. Cronbach's alpha test was used to ensure the reliability of the questionnaire. The Kolmogorov-Smirnov normality test, Correlation Coefficient test in SPSS software, and Structural Equation Modeling in Smart PLS software were used for inferential data analysis.

The current research has been carried out in line with research related to rural-urban links, with the difference that it has examined the relationship and effectiveness of each institutional-management, social, and economic factors with capital outflow from the villages and its transfer to the cities. In the Kolmogorov-Smirnov test, the significance level of the test for all variables is less than 0.05. This means that the data distribution of these variables was abnormal. Thus, the non-parametric test of Spearman's correlation coefficient was used to determine the correlation between variables. In the Spearman correlation coefficient test, the significance level of the test between all research variables was less than 0.05. So, all the studied variables have a significant positive and direct correlation. The results of Cronbach's alpha coefficient and composite reliability of the variables show that the value of Cronbach's alpha coefficient and composite reliability is acceptable for all research structures. According to the results of the structural models seen in the second-order confirmatory factor analysis model, institutional-management factors with a factor load of 0.315, social factors with a factor load of 0.309, and economic factors with a factor load of 0.124, respectively, are the highest. According to farmers, they have the least impact on capital outflow from the villages. Therefore, the development and support policies of the government as an influential factor in the villages can lead to social and economic development by strengthening the villages' infrastructure and increasing the villagers' motivation to keep their capital in the village by guaranteeing economic security. Accordingly, the uncertain economic outlook for rural capitalists will be a justifiable reason for them to prefer to invest in a more secure environment (in the city).

Capital outflow is a phenomenon with institutional-management, economic, and social roots; if it flows from rural areas to cities, it will intensify the inequality and instability of villages. Based on this research, the most important institutional-management factors that affect the capital outflow from the village, which in the main of them are the weakness of the government sector's support and policies from other sectors (private, cooperative, and small operators) for investment in the village, the lack and weakness of the government's investment in rural infrastructure (such as physical development, cultural development, etc.). Also, the most important economic factors from the point of view of the activists of the agricultural sector in the villages are income generation and ensuring the return of capital, areas of investment in the city (land and housing, industries, banks, etc.), investment efficiency in the urban economy, employment security and activity in the urban economy. The benefit of investing in the city compared to the countryside and the flexibility of capital in the city can be mentioned. Among the most important social factors (aligned and related to economic reasons) are the motivation to invest in the urban economy (due to profitability and capital efficiency, return on investment, government support, etc.), well-being, and a sense of psychological and social security. Investing in the city is pointed out. Based on the results of this research, some suggestions are presented as follows:- Increasing government investment in rural infrastructure (such as physical development, cultural development, etc.); Applying incentive policies for villagers to invest in different sectors of the rural economy (for example, tourism, information and communication technology, etc.) and activating local managers and giving them more powers;Giving investment motivation and economic security to the target groups (major farmers), such as reducing taxes in case of keeping capital and circulating it in the cycle of the rural economy.

 The coronavirus disease 2019 (COVID-19) is still a global leading public health issue, especially in low- and middle-income countries (LMICs). Vaccine hesitancy can decelerate the effect of mass vaccination programs. This study aimed to assess the determinants of COVID-19 vaccination acceptance and its relationship with the perceived risk of COVID-19 among the Iranian population at the beginning of the vaccination program.

In this cross-sectional survey conducted in June 2021 in Tabriz, Iran, 500 subjects aged 18-64 years were investigated. The collected data included the demographic variables, participants' previous COVID-19 infection, history of the COVID-19 infection and mortality in the participant’s family members, perceived risk of COVID-19, and COVID-19 vaccine acceptance. The data were analyzed using the SPSS software version 16. Independent t-test and logistic regression were also performed.

The acceptance, doubt, and rejection of COVID-19 vaccine were reported by 232 (46.4%), 129 (25.8%), and 139 (27.8%) cases, respectively. Multivariate regression analysis showed that the age, education level, profession, and perceived risk of COVID-19 were significantly associated with the acceptance of the COVID-19 vaccine.

The acceptance rate of the COVID-19 vaccine was not optimal among the studied population at the beginning of vaccination program, and about half of the participants reported the vaccine acceptance. People with low education, low perceived risk level for COVID-19, and younger people may have been considered a high-risk group for doubt or rejection of the COVID-19 vaccine.

In order to determine how well component extraction techniques (principal component analysis and factor analysis) and variable (feature) reduction techniques (correlation-based and relief techniques) perform in identifying the likelihood of future stock price crashes, the current study looked into these techniques' performance and effectiveness. To do this, a sample of 80 companies listed on Tehran Stock Exchange between 2006 and 2017 was chosen, and 17 often used major characteristics influencing the probability of a stock price drop were found by studying the literature. The criteria for evaluating the efficacy of the procedures under consideration included the mean absolute magnitude percentage error, root mean square error, and coefficient of determination. In comparison to the use of all key explanatory variables, the results showed that variable reduction and component extraction strategies work significantly better and are more effective at predicting the likelihood of future stock price crashes.

After converting to Islam in the Transoxiana, the Turks retained much of their previous religious beliefs. The victory of the Seljuks over the Romans in the battle of Malazgerd (463 AH / 1071 AD) caused the Turks and Islam to find their way to Anatolia. There were two types of Turks living in Anatolia: the civilized and urban Turks of Central Asia settled in the urban centers of Anatolia and the nomadic Turks settled in the villages and summer areas. The Seljuk policy in settling the Turks led to clashes between the nomads and the settlers. The nomads were dissatisfied with the government due to being deprived of sources of wealth; therefore, they revolted against the Seljuks. The Babaian uprising is a clear example of these uprisings, which, despite its failure, weakened the Anatolian Seljuk government. Using the descriptive-analytical method, this research aims to investigate the factors that formed the Babaian uprising. Thus, the author seeks to answer the following two questions: What factors caused the Babaian uprising? What was the contribution of each factor to the uprising? In response, two hypotheses have been proposed: a) Economic, political and religious factors played a role in the Babaian uprising. B) Although this uprising had a religious form, it seems that the main motive of the insurgent was to achieve economic goals

The efficiency of the agents of the Imamate organization is one of the important and essential factors for the realization of the goals of the Infallible Imams, peace be upon them, which is always the focus of thinkers in this area. The monotheistic view of the infallible imams (peace be upon them) required the structure of society management and its essential role in the formation of society's behavior and the material and spiritual fate of the people; Indicators should be considered in the selection and employment of human resources. This article deals with two indicators of economic and political health in a descriptive and analytical way from the perspective of the lives of the infallible imams, peace be upon them. The result of this mapping is that by considering the indicators of anti-corruption, trustworthiness, outsourcing, avoidance of worldliness, popularism, insight and political influence, it is possible to select efficient human resources of the Islamic administrative system

Predicting changes in meteorological variables in the long run is of great importance in the study of climate change. The aim of this study is to provide a perspective of temperature and precipitation changes in the western and southwestern regions of Iran using climate-generating radiation induction scenarios LARS-WG and display the results in GIS environment so that in the coming decades macro-planners In order to adopt compatible methods and reduce the consequences of global warming. For this purpose, daily precipitation, maximum temperature, minimum temperature and sunny hours of 34 meteorological stations were studied. The climate of these stations was determined based on the Domartan classification method. LARS-WG statistical exponential model for analyzing historical data on daily rainfall, solar radiation, and daily maximum and minimum temperatures at the stations under study and to simulate future meteorological data were utilized with considering RCP4.5 and RCP8 climate scenarios. The results showed that the model can simulate with high accuracy. The 1980-2018 statistical period was compared with the 2018-2038 statistical period under the RCP4.5 and RCP8.5 scenarios; the results for the stations under study showed a general process of increasing temperature and decreasing precipitation.

This paper develops the new logarithmic higher-order shear deformation theory (LHSDT) incorporating isogeometric method for free and forced vibration analyses of functionally graded carbon nanotubes reinforced composite (FG-CNTRC) plates. In this theory, a logarithmic function is employed to approximate the distribution of shear strains along the plate thickness which satisfies the condition of zero tractions on the top and bottom surfaces of the plate. The plate is assumed to be fabricated from a mixture of carbon nanotubes (CNTs) and a polymeric matrix. The CNTs are either uniformly distributed or functionally graded (FG) along the thickness direction of the plate. The modified rule of mixture scheme is applied to estimate the effective mechanical properties of FG-CNTRC plates. The governing equations are derived from Hamilton’s principle. Furthermore, the Newmark approach is utilized to predict the temporal response of FG-CNTRC plates under different transverse dynamical loadings. The applicability and efficiency of the present formulation in predicting vibrational characteristics of FG-CNTRC plates are investigated through an extensive set of numerical examples considering different configurations of the plate. It is revealed that the computed results are in excellent agreement with other solution methods extracted by the 3D model and other plate theories. Eventually, a detailed parametric study is conducted to explore the influence of related parameters on the natural frequencies and temporal response of FG-CNTRC plates.

Fractional slot concentrated winding (FSCW) configurations are drawing more attention in the area of brushless PM machines due to high power density, high efficiency, low copper consumption and high reliability. These characteristics make them suitable candidates in applications where high power density and efficiency are required, such as electric ship and submarine propulsion systems and electric vehicles. Detailed discussion regarding the choice of pole-slot combination is addressed form the viewpoint of winding factor, unbalanced magnetic pull, cogging torque and case-study conditions leading to narrowing down the decision choices to two candidates. A hybrid design algorithm is proposed for designing the two interior PM (IPM) FSCW machines obtaining the advantage of high processing speed and high precision simultaneously. A comprehensive comparison is made between the two IPM FSCW machines by analyzing the spatial harmonic spectrum of armature and rotor flux density distribution in air gap region. In order to validate the design and simulation results, a 2kw, 1500 rpm IPM FSCW generator is prototyped and the test results are compared with the simulation data. According to the experimental results, the measurement and simulation data have good level of consistency in which the error rate for no-load back-emf is 3.5% and for the full-load terminal voltage is 4.3%.

In this research, an approach based on the isogeometric method is developed to study the free vibration behavior of functionally graded carbon nanotubes reinforced composite skew folded plates. In this method, non-uniform rational B-splines basis functions are used for approximation of the geometry as well as the displacement field. The plates are reinforced by single-walled carbon nanotubes which are assumed to be graded through the thickness direction with different distribution patterns. The effective mechanical properties of composite skew folded plates are captured by the modified rule of mixtures approach. Modeling of the skew folded plate is accomplished by two non-uniform rational B-splines patches which is one of the strengths of the research. The equations of motion of each patch are derived based on classical plate theory and then are discretized using non-uniform rational B-splines basis functions. The final form of the discretized equations is generated after the transformation of the element matrices of each patch and then applying the continuity conditions along the boundary of the patches with the aid of the bending strip method. Afterward, several numerical examples are provided to prove the accuracy and reliability of the proposed formulation. The results exhibit that the present approach can precisely predict the natural frequencies of skew folded plates with a low computational cost. Eventually, a set of new results are presented for different geometrical and material parameters of the skew folded plate.

In the past two decades, worldwide interest in the natural dyes obtained from plants has rapidly increased, and a diversity of health and environmental benefits were found or argued for the practice. Cloves are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum, which their chemical compounds makes them suitable for the application in dyeing process. The important essential chemical constituents of clove include acetyl eugenol, beta-caryophyllene, vanillin, crategolic acid, gallotannic acid, and methyl salicylate. In this study, clove as the plant-derived dyestuff was used for dyeing the wool yarns to be investigated the effects of the different dyeing parameters including dyeing methods, acid and mordant type, and concentration and dyeing temperature in the yielded dyeing. The dyeing capability of the samples at different concentrations and temperatures was investigated using the spectrophotometer method and Beer–Lambert law. The results show that applying high concentrations of dyestuffs resulting the maximum dyeing ability of the samples at 60 °C. At the low amount of dyestuff concentrations, the increase in temperature from 30 to 80°C showed no significant difference in the dyeing ability of the samples. The use of different mordant created different shades such as yellow, brown, and dark gray. Furthermore, it was proved that using the 80% (weight of dye/weight of wool yarn) dyestuff through the Metachrome process would yield the optimal conditions for dyeing the wool yarn with the clove dyestuff. Finally, although the type of acid used did not affect the resulted shade, it affected the amount of exhaustion the wool yarns.

Study of the remained resources from south of Saudi Arabia indicates that in spite of mythic understandings of some historians,Ṭabari's narration demonstrate that Tabābi ̒a kings had march to China and Tibet borderlines.This is not only in agree with fourth century Yamani stone writings,but also it is near to historical realities remained from sources of per-seventh century.Current article with scientific approach in history and by a descriptive analytic methodology aimed to find response to this question that what is the mean of reports from this event and what geographical and characteristics are included.On the basis of our study we can say that this march is in accord with clues of geographical history and probably Tibet is current Tajikistan. Many reasons as tribute to the Sāsānids by the Hephthalites, Qobād weakness caused by Mazdakiys and their improper supports from Kendiys is a rival of Munzers household lead to some Tabābi ̒a marches.

Outdoor thermal comfort is one of the most important issues affecting different activities of human life. The purpose of the present study is to help to better understand the factors influencing outdoor thermal comfort such as the width of sidewalks, dimensions of urban gorges and their orientation. In this study, four main passages of Kermanshah metropolis namely Modarres, Kasra, Nobahar and Taqghobostan were selected and studied. The meteorological data required for a 59-year period from 1951 to 2010 were obtained from Kermanshah Meteorological Department. Environmental elements were also taken for each passage in the field. The existing data was eventually imported into Envi-met software. Simulation results show that PMV index values for summer and winter are only in thermal comfort  at the north-south of Nobahar and Kasra passage  with direction shift from east-west to north-south in winter shows only 0/40 PMV index of improvement. Increasing the width of the passages by 50% increased the temperature in summer and winter. Increasing the height of buildings around the streets of Modarres, Kasra and Taghobostan also improved the summer thermal comfort and the reverse effect in winter.

Rural guide plans are provided and implemented to provide the situation for development of rural areas. The main objective of the rural guide plans is to organize the rural texture and organizing all the activities that are performed in the villages. Locating the land uses in rural guide plans should be done in a way that will not diminish with passage of time or changes shall be minor and ensure the sustainability of rural development. On this basis, all the organized and regular activities which have been made for organizing and rehabilitation of physical environment of rural settlements have been considered by planners. The purpose of the study is to evaluate the satisfaction of rural communities with regard to locating the proposed uses of rural guide plan in the sample villages of Khanmirza.The present study is of applied one from the view point of aim and based on nature is of analytical–descriptive one The data obtained through the questionnaire with a sample size of 316 people in five rural settlements in which five years have been passed from the implementation of Guide Plans in them. The apparent reliability of the questionnaire, Cronbach's alpha coefficient (0.854) was approved. The data analysis was performed using SPSS software. The research findings indicate that locating the proposed uses in guide plans has the most compatible with the requirements of rural communities .In contrast, the value of t-statistic for social and economic dimensions is 3.2 and 2.7 respectively, which indicates a lack of proper attention to the social and economical indicators is in preparing and conducting projects.

Conflict modeling and analysis have been investigated within many disciplines. Metagame based methods are the most comprehensive models that have been used for conflict modeling and analysis. The literature review outlines that common interest in the gas field shared between Iran and Qatar and lack of power balance between the two parties have caused conflict. Moreover, no serious study has been done on the aspects involved in the conflict.
In this research we acknowledge the lack of a comprehensive study on the gas field shared. We employed confrontation analysis and drama theory to shed light on the potential issues involved in this case. Based on the data collected from several in-depth interviews, we present a framework depicting influential factors on the case of shared field between Iran and Qatar. While research findings show that negotiation under the current circumstances is impossible, a positive situation for Iranian side in the future is predicted.
The research also suggests an appropriate strategy not only to resolve the conflict in Iran-Qatar partnership, also facilitate the creation of fruitful collaboration between the two parties.

Acute normovolemic hemodilution is an available technique to decrease the side effects of allogenic blood transfusion. The aim of this study was to compare acute normovolemic hemodilution with allogenic blood transfusion in adult patients who were scheduled for femoral fracture surgery. In this randomized controlled trial, 50 patients were randomly allocated into two equal groups. General anesthesia was induced in all patients. After induction of anesthesia in case group (n=25) 500 ml blood was taken from patients, while the circulating blood volume was restored by ringer solution (3ml ringer for each 1ml of blood withdrawn). The blood extracted was re-infused during or after surgery according to the patient''s hemoglobin and hemodynamic parameters. In case there was further need for blood, allogenic blood was transfused. In the control group (n=25), only allogenic blood was transfused according to estimated patient’s blood loss. Patients'' assessment was performed by an anesthesiologist who was blinded to the patients'' allocation. Demographic and laboratory data were similar between both groups. Pre- and postoperative laboratory tests were similar in both groups except in mean platelet count (p=0.001). The patients in the two groups were comparable regarding hemodynamic parameters. In the control group, 11 patients needed allogenic blood transfusion and in the case group, allogenic blood was transfused in 4 patients (p=0.03). This study suggested that acute normovolemic hemodilution autotransfusion reduced allogenic blood transfusion in patients who underwent femoral fracture surgery.

Maize is one the major utilization type in Gobadloo region where placed in East Azarbaijan porivince, North-West of Iran, so performance of land suitability evaluation and land production potential prediction are very important for knowing environmental limitations and planning proper cultivation. FAO guidelines on the land evaluation system were widely used for the land suitability, so soil morphological and analytical data were carried out for 16 land units. Then, based on AEZ model, radiation thermal production potential for Maize was estimated and then soil indices which indicate the extent of soil limitations effectiveness on production reduction, was calculated by the square root formulas. Finally land production potential was calculated by multiplication of the soil indices and radiation thermal production potential. The results reaveald that parametric methods (square root and storie formulas) uncorrected land indices had lower values than which what it was expected in real conditions. For solving this problem land indices were corrected and the results improved land suitability classes. Coefficient of correlation values between land production potential and observed yield were 0.79, 0.84, 0.86 and 0.9 for uncorrected storie, uncorrected root mean square, corrected storie and root mean square models respectively. Based on the results, can conclude that Mean Absolute Error is able to predict yield better than that other methods because of higher regression coefficient and lower error.

Enjoying the twelfth largest coal reserve in the world، only one percent of Iran’s energy consumption basket is supplied by coal. Now، Iran’s energy economy is under the influence of natural oil and gas resources، causing other more profitable energy resources to be neglected. The Underground Coal Gasification (UCG) technology is a procedure to transform the underground coal into gas، resulting in improving the recovery of coal layers with different thicknesses and depths. This technology may be considered as a strategy to feed the domestic gas network with the synthetic gas of UCG. Therefore، Iran’s gas export capacity will be improved، helping domestic and foreign economy of energy. Implementing and using the UCG technology in Iran will help us take a leap toward the goals of upstream documents and orders of the Supreme Leader in the fields of oil and gas.

Sugar beets are used primarily for production of sucrose, a high energy pure food. The identification of suitable locations for the production of this valuable plant is of crucial importance. In this regard, land evaluation suitability determination spatial Mediterranean land evaluation method is one of the main management procedures in sustainable agriculture for planning. The purpose of this research is using Mediterranean land evaluation to land suitability evaluation for sugar beet in an area with 7990 ha extension, which is located in North of East Azerbaijan province (Golfaraj-Jolfa). The goal of this study is land planning of Golfaraj (Jolfa), thus soil morphological and analytical data were carried out for 17 land units. Based on each model effective parameters, bioclimatic deficiency, land capability and qualitative land suitability were determined using above mentioned models. The result of Terraza model showed that rainfed cultivation is possible with 20-40 percentages in yield for sugar beet. Also, considering some of the management recommendation such as identifying the sensitive time of crops for irrigation, reduce the water consumption without any negative impacts on annual yield. According to Cervatana model results, total area was distinguished as good. Therefore, qualitative land suitability evaluation of susceptible lands using Almagra model revealed that 24.3, 39.9, 8.1 and 27.7 of total area can take place in excellent (S1), suitable (S2), moderately suitable (S3) and unsuitable (S4,S5) respectively by soil texture and carbonate. In summary, MicroLEIS DSS tool appears to be useful in semi-arid regions, such as Golfaraj area located in East Azerbaijan (Iran), to formulate sustaining agro-ecological systems.

There are so many definitions about failed back surgery syndrome as persistent back and/or leg pain despite having completed spinal surgery. But when we proclaim that surgery is finished and how we know that something new doesn’t occur that by itself need special attention and treatment. In our center we observe many cases assume of failed back surgery syndrome to manage. We learnt that majority of this cases can be treated and getting good result with meticulous thorough work up to clarifying their undergoing pathophysiology. In this perspective there should be another definition for failed back surgery syndrome this definition should be only allocated to those patients that after full evaluation we cannot find any anatomopathologcal reason to explain their ailment scenario, in other words we have here a chronic pain syndrome case when we say FBSS. We seek an important goal by stressing in lexical debate on the term FBSS and the goal is to emphasize on planning an exhaustive evaluation of any patient with previous surgery on his or her back. Many of these patients has stenosis, recurrent herniated nucleus pulposus (HNP), pseudarthrosis, new instability, adjacent level disease and so many like that. All of this are surgically curable sufferings and we haven’t yet failed. After correcting those pathoanatomy we have small group of patients with really chronic pain disease that they also not failed back surgery cases they are the patients who need multimodal treatment option which exactly every pain specialist is thoroughly acquainted with. As lumbar surgery continues to grow in prevalence, so will the number patients suffering from FBSS. It is important for physicians treating this population to expand their knowledge of FBSS etiologies and appropriate diagnostic imaging modalities, combined with confirmatory diagnostic injections, and proper technique for interventional pain procedures. Therefore we propose to substitute the term FBSS with previously operated back syndrome which in addition to expunge the negative meaning of failure for the surgeon and patients it denote the different clinical situation of this patients which need special evaluation and treatment algorhythm.

The empowerment and enthronement of Reza Shah was achieved through the assistance of a group of intellectuals and political activists, who wanted to put an end to the chaotic conditions of Iran, promote political centralization and establish discipline and security around the country. One of the intellectuals who assisted Reza Shah at that time and supported him until and after taking the throne was Abdolhossein Teymourtash. After Reza Shah’s enthronement, Teymourtash was appointed as minister of the royal court of the Pahlavi dynasty. Again at this post, he was very helpful to Reza Shah. However, he was suddenly dismissed as a minister of court, sent to prison and tragically killed there. This research aims to scientifically and methodologically study and analyze the reasons for Teymourtash's rise and fall. In this research, the author aims to answer the following questions: 1- why did Reza Shah, among several Possible choices, appoint Teymourtash as a Pahlavi court minister? 2- Despite the outstanding services, Teymourtash provided for the Pahlavi administration, why did Reza Shah suddenly dismiss him? In response to these two questions, two suppositions are proposed: 1- Reza Shah appointed Teymourtash as a minister of court due to his merit and also because of his Continuing efforts to pave the way for Reza Shah’s enthronement. 2- The increasing power of Teymourtash as a minister of court and the fact that he was becoming the second most powerful person of the country, made Reza Shah, a suspicious dictator-worried for the future of his throne. He therefore dismissed Teymourtash.
