Wheat is a major agricultural crop in the Sistan region with a key role in local economy. The present study aimed to economically explore the efficiency of wheat production over the 2014-2016 period with the window data envelopment analysis (WDEA) approach. Also, the Malmquist productivity index was employed to assess the productivity of wheat growers in the study site under variable return to scale with the input-oriented approach. The results show that average annual efficiency of Zabol, Zehak and Hirmand counties are 0.96, 0.95, and 0.96, respectively, implying that these agricultural units are efficient. Also, the values for the Malmquist productivity index show that the highest average variation of total productivity of 0.96 was for Hirmand County in the studied period, showing the low productivity. According to the results, an influential factor underpinning the variations of total productivity of wheat growers was found to be technological variations. Thus, it is recommended to develop some plans to improve the efficiency and productivity of wheat in environment-agriculture sectors of the studied region.

The learning system provided by the municipalities is one of the most important motivating factors make citizens to participate in urban management plans such as source separation of wastes. In the past years, Tehran municipality has been focusing on providing different training in waste management and specifically source separation, which has not been able to attract public participation. The aim of this paper is to study the failure causes of learning systems and to address the shortcomings in the form of distance learning to provide the most effective learning method. In this regard, the Khan conceptual model has been used in the fuzzy analytic hierarchy process. Finally, the results of the 100 paired comparison questionnaires in this study, which were obtained using Khan's conceptual model and fuzzy theory, introduced mobile applications as the best method of distance learning. The strengths and reasons for its selection, which were obtained from interviews conducted by residents of district 16 of Tehran municipality, are described. To compare between different types of distance learning methods, 8 criteria were used in 25 proposed subcategories categorized by Khan's conceptual model that could integrate the concepts and basis of a standardized and successful distance education system into a fuzzy decision model.

Due to the importance of the government size impact on economic growth, the current study investigates the impact of government size on economic growth in economies of the developed and developing countries by using a panel data approach over the period 1990-2010. The results indicate that government size has positive effect on economic growth and negative effect on per capita production growth in developed countries, but, it has negative and significant effect on economic growth and per capita production growth in developing countries. Therefore, reducing the government size is very important for increasing the economic growth in developing countries such as Iran. Also, based on the results, investment growth and consumption expenditure growth have positive and significant effect on economic growth and per capita production growth in both developed and developing countries. However, Trade openness effect on economic growth and per capita production growth is positive and significant in developed countries, but is negative in developing countries.

Natural disasters in various forms have been identified as destructive phenomena during the life of earth planet and are also a serious threat to the inhabitants of the planet. Therefore, this issue leaded to the formation of a process called crisis management which includes activities occurring before, within and after the event to reduce the vulnerability. The country of Iran is considered as one of the world's affected countries from natural disasters due to its geographical location and climate diversity. In this research, the role of crisis management in reducing the socio-psychological vulnerability of affected citizens in 2003 earthquake of Bam city was investigated. Library and field study methods have been used to collect information in this study. Also, a qualitative-quantitative method was used to analyze the data by employing the theme method and consequently the most important factors affecting the citizen's socio-psychological vulnerabilities of Bam city after the earthquake were identified.

The purpose of this paper is to manage the crisis caused by nano-technology in the petrochemical industry (Emam port). The collection of information contained in the petrochemical industry On the application of nanoparticles and the problems created by preparing questionnaires and to provide it on two levels: Managers and technical experts then analyze it done And also to study the biological effects of nano-technology in the petrochemical industry on the environment, economic and social examined, The results showed that more than 90 percent of nanoparticles in Emam port in terms of dealing with the crisis are senior technical staff. Results showed that higher-than-average exposure to nanoparticles staff on mental health and quality of life of employees working in a negative effect. In other words, no matter how critical nanoparticles increase the exposure of employees with mental health and quality of work life of senior technical staff decreases. Based on the results nanoparticles crisis, global warming and the mortality rate of fish cumulative effect this means that if the amount of exposure to nanoparticles is critical to global warming exceeded is added. Frequently caused by the publication of critical nanoparticles butadiene (RA) under the headings inappropriate responses health-environment, frequently economic and social responses in approximately 43/48% of the total variance of responses caused by the release of nanoparticles are critical.

This paper is to study the resource curse applying annual data from 2002 to 2016 for the Organization of the Petroleum Exporting Countries (OPEC) members i.e. Algeria, Iran, Kuwait, Nigeria, Qatar, Saudi Arabia, United Arab Emirates and Venezuela. For this purpose, there were concerned the interactions role of resource abundance and institution quality, and their marginal effect of the countries’ economic growth. Results show that resource abundance and investment have a positive significant effect on the economic growth. Yet, initial income level is observed to have a significant negative effect on the economic growth. In addition, the results showed that the positive effects of resource abundance in the OPEC countries were reduced with increasing institutional quality. The empirical results rejected the resource curse assumption for OPEC, because the effects of resource abundance on the economies of OPEC were significantly positive. Results of the present study indicated, since the institutional structure of these countries is based on oil, the lack of oil revenues in short-run can have a negative effect on their economies.

A direct expansion (DX) HVAC system is an efficient way to supply fresh and dehumidified air to a built environment. To improve the efficiency of a conventional DX system in hot and humid regions, fresh air dehumidification and conditioning systems with energy recovery measures are the key equipment to reach such a goal. To achieve this goal an integrated system is proposed. The integrated system substitutes the reheat coil with an extra condenser in series arrangement with the main condenser to reheat the supply air while mixing the ventilated air with condenser cooling air. Modeling has broken down into two parts. Psychometric part which has been modeled using EnergyPlus and EES software, and DX system in which data is received via psychometric part, and has been modeled and evaluated by EES software. The case study is located in Bandar-e-Abbas city, quasi-dynamic modeling is to be conducted and results will be analyzed correspondingly. The integrated system’s energy saving is 32-48%. Also, system’s COP has increased from 1.55 to 3.46 for outside air fraction (ventilation rate) of 0%, and from 2.37 to 3.47 for outside air fraction of 100%. Finally the payback period is roughly less than 4 years.
