Construction of hydropower, wind, solar, nuclear, geothermal and recycling power plants. It is one of the solutions that the experts in this field of energy production have succeeded so far and have made significant progress in the world by presenting appropriate plans. Iran also did not hold back from this convoy and by building hydropower plants and using the potential of the country's surface water, which amounts to 50. TVVH / y annual energy production by this type of power plants, has taken a step that the vision It puts a light in front of it. Attention and emphasis on sustainable and economic development of energy supply in the national sphere, reduction of greenhouse gases to prevent environmental degradation, expansion of production capacities and increase of energy revenues, replacement of fossil products including oil and gas in power plants, maximum use. The potential of the country's hydroelectric power and ultimately the economic efficiency of this type of power plants during operation to balance the supply of cheap energy to consumers is one of the goals of the energy production sector in our country. In order to implement these goals, the Ministry of Energy based on coherent and purposeful planning in order to realize the full utilization of hydropower generation facilities, which in this context in the framework of energy development and diversification of Iran water and power resources development company, which is organized. He is one of the specialists in the design and construction of hydropower plants, and in the form of this company, he was able to carry out the planned programs in the hydropower sector.

In this research, thermal and catalytic pyrolysis and the amount of liquid product obtained from pyrolysis and its composition have been considered. In pyrolysis of each polymer, the amount of liquid product was increased by performing several optimization steps on the reactor. According to studies, among the three catalysts used, the FCC catalyst produces the most liquid product and the HZSM-5 catalyst releases most of the product as gas due to the small pore size. By gas chromatography test, the percentage of liquid product components, aromatic, olefin, paraffin and naphthenic in the product were obtained and also liquid product components were obtained based on the number of carbons. The results of gas chromatography test show that a significant percentage of the product in pyrolysis with FCC catalyst is olefins. Evaluation can be said that in pyrolysis of rubbers (polybutadiene rubber and styrene butadiene rubber) due to the presence of many double bonds in their structure and the formation of many radicals during pyrolysis, a pyrolysis process will be multi-stage and unlike plastic pyrolysis. The hydrocarbon liquid product is extracted separately and in several stages. The trend of temperature changes in pyrolysis of tires is also increasing and decreasing.

Referring to the need for three factors of capital, materials and machinery and manpower in the implementation of development projects in the country, he said: "The private sector will never accept investment in projects without considering the profit." Engineer Droudian added: "Since water projects are not feasible in the short term, so the capital is locked for a long time and on the other hand, even after operation, the project does not have a good return." Referring to finding a way to improve the efficiency of projects, he said: 94% of the country's extracted water is consumed in the agricultural, industrial and domestic sectors without any restrictions and disproportionate to the efficiency and price of water input, and according to the water market in Iran, efficiency The desired capital will not be realized after the completion of the project. "Many investors and contractors believe that in the implementation of projects by the private sector, projects are expected to be key in hand so that the private sector can put the projects into operation in the shortest possible time, and as a result, the project," he said. Have an acceptable profitability.

In the recent century, with the advancement of technology and the development of technology, the construction of various tools that have led to effective and more accessible communication between humans and solving many of their needs, on the one hand, has promised an easier life, and on the other hand, excessive or incorrect use of these tools has destructive consequences for humans and the environment. A clear example in this field is the increasing growth of urban vehicles, which on the one hand has made it easier for people to travel in big cities, and on the other hand, it has caused a lot of pollution, including air pollution and noise pollution, and as a result, it has caused many physical and mental discomforts. Mental and even physical injuries can affect human behavior and affect the way he communicates with others and the environment around him. Of course, we should not neglect the fact that the negative effects of pollution will not only affect humans, but it can have destructive effects on all natural ecosystems, which are certainly not unrelated. No one can deny the fact that water pollution will have destructive effects on aquatic life, and humans who use these resources will not be spared from its destructive effects. Of course, perhaps as much research has been done in the field of physical effects of pollution, it has been neglected in the field of its behavioral effects. Maybe many people cannot make a connection between the two phenomena of pollution and behavior. Therefore, in this research, it has been tried to investigate the effects of these pollutions on the psyche and behavior of humans and other creatures as much as possible.

Graphene oxide (GO) produced by intense oxidation of graphite in Hamer method is an ideal nano carrier for drug and gene delivery. The number of graphene oxide layers used for drug delivery is between one and three layers (the total thickness of the layers is 1 to 2 nm) and their size is between a few nanometers and several hundred nanometers. This material has unique structural features such that its specific contact surface is very high (2630 square meters per gram) and on the other hand, it is full of oxygen-rich groups; For this reason, this two-dimensional material has good biocompatibility and physiological solubility, and its stability is also suitable. The mentioned characteristics have made this material a suitable option for loading drugs and genes through chemical correlation. The presence of hydroxyl (OH) and carboxyl (COOH) functional groups in the structure of graphene oxide has caused GO to have good correlation with various systems such as polymers, biomolecules, quantum dots, iron oxide nanoparticles (Fe3O4), etc. It is possible to predict various applications for graphene oxide in this field used graphene oxide for water-insoluble aromatic anticancer drugs.
