The current research is based on the theory of Lucien Goldman The creator of the work of art is the representative of a particular class whose collective thinking turned into a productive work by his author, the comparative-analytical study of the social sources of the poems of Donqle and Hosseini as intellectuals of the popular class. Prodotti explains the presence of collective thought in their mental network by examining the ideals of these two poets. The achievement of this study suggests that both poets have a duty to distinguish and to expand the collective thinking of ideals that are summed up in the land, justice and culture. They succeeded in fulfilling this mission against the society and the people's classes and their lost ideals, and obstacles to achieving these aspirations, which were often the result of malicious foreign policy and, in some cases, the mismanagement of internal leaders. , Identify.

Aluminum alloys are desirable in industry due to their excellent high-strength to weight ratio, corrosion resistance, and weldability. However, at room temperature, the formability and the surface quality of the final product of these alloys are low. So in recent decade, new process, hot metal gas forming, has been introduced. This paper investigated new method of hot aluminum alloys forming using gas. Experimental test for bulge forming was designed and made. In addition to experimental test, finite element analysis of process was done. Results showed that hot metal gas forming provides highest forming temperature for aluminum alloy blank and with increasing blank temperature up to optimum temperature of hot forming, there is reduced pressure forming and significant improvement of formability. Results of experimental test and finite element analysis including determination of optimum temperature for forming of special aluminum alloy, maximum formability in this process, required forming pressure, minimum thickness, thickness and temperature distribution were conformed.
