This article studies the state of socialism in China and wants to know the extent of using socialism in constitutions of mentioned countries and its position in terms of efficiency in the rules of these countries. In societies which socialism approach is dominant approach tend to reject private ownership and prefer public benefit instead of individual benefit. Therefore, socialism is against economic liberalism.

The heat transfer coefficient of fluids plays a vital role in increasing the thermal efficiency of the fluids. In the meantime, the new technology of Nano fluids has made clear horizons in thermal transfer studies. In this study, the effect of the magnetic field on the coefficient of fluid transfer of the base fluid of distilled water and the fluid containing the magnetic nanoparticles (Fe3O4Water), called frucloid, was investigated. According to the results, the magnetic field does not have any effect on the distilled water fluid, but when the Ferro fluid is used as a fluid, the heat transfer coefficient increases as the field strength increases. Also, by increasing the concentration of magnetic nanoparticles in the fluid, we see an increase in the heat transfer coefficient. In this study, the effect of magnetic field intensity, nanoparticle concentration and field direction on the relative viscosity of the Ferro fluid was also investigated.

The several methods have been proposed to reduce propagation of CO2 to increase density of carbon dioxide gas in atmosphere of earth planet e.g. CO2 flooding for the sake of underground extraction and storage Consuming fossil fuels has led to production of 27 billion tons of carbon dioxide throughout the world where it is followed by many adverse effects on environment. Thus, presentation of strategies for controlling and reduction of propagation of such gases is deemed as one of the foremost research preferences out of which propagation of greenhouse gases and injection of them in geological formation is one of the paramount techniques for reduction of propagation of greenhouse gases. This process is an early-efficient process that can cause reducing the great volume of dissemination of this gas through atmosphere. In this technique, CO2 is extracted from propagation sources and transferred by pipeline to the injection site and stored in subterranean formations through injection wells. On the other hand, linking this process to oil over-extraction operation is one of the methods for making CO2 gas storage process economic. The great volume of CO2 is injected into the reservoir in this process that increases oil extraction and justifies totally this operation in terms of cost-effectiveness. The studies show that if CO2 is injected into the reservoir under optimal conditions (suitable injection model and operational conditions and with CO2 in purified mode), it not only leads to producing great amounts of oil left in reservoir, but also it can prepare the ground for storage and prevention from wasting the huge amount of this greenhouse gas. The oil over-extraction technique by CO2flooding is a totally well-known technology. Carbon dioxide, both in miscible and or immiscible form, can favorably affect pressure of reservoir. CO2 causes inflation in oil in miscible form and it causes reducing viscosity of crude oil. The reduced viscosity of CO2 is led to easier motion of oil toward the produced oil well. Similarly, the immiscible CO2 also increases pressure of reservoir. Combination of these factors increases rate of oil extraction. The rate of increase in efficiency is at least 25% in this technique, but the real outcome is much noticeable because by injection of CO2 gas into oil reservoirs, one of the foremost environmental pollutants is reduced. It has been discussed about method of storage and injection of CO2 into oil reservoirs in this paper.

Since productivity is the strategy that its increase has been discussed as the key to economic growth and development in recent decades, the increase in the productivity of manufacturing firms, especially in the labor force and human capital can lead to economic growth, and improvement in the economic situation of people. Therefore, considering the importance of the issue, this study is trying to examine the factors influencing total factor productivity in the manufacturing industries of Kermanshah province using panel data model in the period of 1989-2011. The findings show that the use of labor force leads to improved total factor productivity and the move toward technology and technology-based activities do not benefit the society or improve total factor productivity.

We seek to measure the function of the switching model in estimating the value at risk for the formation of index portfolios. The switching model is explicitly designed to solve the risk managers' problem who do not trust a particular value-at-risk model and allows the model to compute the value at risk in different times and conditions. In this study, predictive methods such as EWMA, historical simulation, Monte Carlo and constant variance model will be discussed. This approach is explicitly designed to predict managers' predictive problems who do not contingent their estimates for a specific VaR model, and allows the estimated model to change over time. This approach assumes that investors at any point of time use only the historical information available to select a model, and the choice of model is based on a pre-determined selection criterion, and then the selection model is used to predict value at risk in another date. The results of the research indicate that the switching model is highly desirable compared to other models over time.

Background and aim: In past societies, the diversity of cultures, languages, and relatives as well as other elements of social life was less than that, and the tolerance of each other's differences and beliefs was not an important issue, but with the growing growth of communications in all fields, On the other hand, the diversity of culture, ethnicity, linguistic and beliefs has increased and, on the other hand, the level of interaction and interaction of the two people has become more and more. The issue of coexistence in human history has never been debated in the present day because people have never The necessity of the difference was not so tangible and widespread as confronting each other with other affairs. Tolerance and respect for others is a factor in the peaceful coexistence of individuals. In a society that is ethnically, linguistically, religiously and religiously diverse, the need for credentials as an indicator of social diversity is felt more and more. The lack of tolerance and the lack of respect for others, especially from Those who are more capable of coercion (in the Iranian family, father and elderly) can strengthen the desire to leave the group and lead to the fact that people in the course of their lives move away from the family along with their preferences Give On the other hand, being away from the family, reducing supervision, as well as frustration from the family, can be one of the most important reasons for the tendency toward social deviations. There is also a lack of tolerance with other people, if they cannot leave the group, it leads to a prolific life and lack of integrity in interactions within the group. The present study investigates cultural factors affecting social tolerance in Ahwaz ethnic groups. Research method: The research method in this study is a descriptive and survey. A field questionnaire was used during the fieldwork. The population of this study is Ahvaz ethnicity.
