Due to universal importance of Tabriz carpet art and presence of specific indicators and motifs in Tabriz carpet art and its potentials, existence of architectural site for representing this art as carpet art museum in Tabriz is necessary. The site of this project is located adjacent to Tabriz Blue Mosque near the museum historical site. It is essential to consider the historical elements and components of the mentioned district identity in historical sites. This research aims at presenting architectural design of a valuable work of Tabriz carpet art museum besides considering criteria of the historical site adjacent to the Tabriz Blue Mosque. In designing Tabriz carpet art museum, the site potentials, concurrent employment of cultural and historical fabric concepts, adjacency of the Blue Mosque and being in direction of historical bazaar and Silk Road have been considered and used as the key pivots in design. This research is a case study based on observation and using architectural tools. Design limitations have been considered in the architecture of the museum near historical fabrics. The design components consist of Tabriz Bazaar cultural-historical architecture elements, utilization of the spatial connection, semantic continuation, respect to the site, preservation of old historical memory in modern approach. The results of this research can lead to successful architecture design adjacent to historical sites.

Nowadays, one of the topics of interest to researchers is the authority of teachers, and fades it in universities. Look at the reality in the society and comparing with historical context motivates researchers to question why some of the professors at the university have less authority. For this purpose, this research is trying to focus on economic and demographic factors, to answer questions. The method used in this research is descriptive analysis using survey techniques and data collection tool is a questionnaire. The population consisted of professors of Kermanshah PNU in the academic year 2011-2012, total number of them is equal to 258. Due to the large size of the population, using the Lin sampling table sample size is 258, which for the study based on striated random sampling were selected. In the present study, face validity assessment method and construct validity based on factor analysis were used. To determine the reliability of the statements of each variable, Cronbach's alpha used. Results using SPSS21 and Amos21 statistical software were analyzed. Mean traditional authority equal to 13.57, then charisma authority13.54, and intellectual authority is 18.72. The dimensions compared with the average expected for above dimension respectively traditional authority 15, charisma authority 12, intellectual authority is 15. The results show that there is a significant relationship between relative deprivation and professor’s authority (r=-0.301), the use of mass media and professor’s authority (r=0.161), monthly income and professor’s authority (r=-0.153). In addition, the results of comparison show that average of the professor’s authority among the courses is different, and this difference based on f test is significant. The average professor’s authority, for people with different degrees is different. The results of Multiple regression indicate that the traditional authority (T=4.335), self-esteem (T =3.925), charismatic authority (T =3.788), and the relative deprivation (T =-2.287), total 0.42 from internal changes explain the value of professor’s authority variables. Furthermore, the results of structural equation shows that Chi square insignificant CMIN is equal to 211.143, square root index mean residual square or RMSEA is equal to 0.075, RMR index or residuals mean square root is equal to 0.098, the Chi-square to the degrees of freedom ratio CMIN.dF in model is 3.199, against the CFI comparative fit index 0.926, and comparative fit index thrifty PCFI, are equal to 0.671 Comparative and thrifty indicators for evaluating the overall model calculated that show collected data to support the theoretical model considered.

Value stream mapping because of being able to understand process bottlenecks, as one of the most common tools for analyzing, identifying and eliminating various losses in operational and support processes are used. On the other hand, inventory management, precise control entry and exit of goods, accurate and timely information about the inventories status and planning, reduce product maintenance costs, including important issues organizations have a special look to it to consider the whole objectives and strategies, making procedures and policies that have a positive effect on the overall organization’s economy. In this paper, the use of value stream mapping as a lean production technique, in a production process to improve inventory control is discussed. This is a tool seeks to reduce losses, especially losses related to inventory by mining a bearing manufacturer companies. In this study, the literature of value stream mapping considered. The current state and future state of the company drawn in order to improve production process and losses in the company's future status. In addition, after drawing the mapping, the results of the simulation software Arena and the final report suggests that the use of this technique has an impact on reduce losses and increase inventory turnover.

Salmas plain is located at the west of Uremia lake and at the 75 km of north of Uremia city. The main river of the plain, called Zulachai, is drained into Uremia Lake. Salmas aquifer is one of the coastal aquifers of Uremia Lake and has hydraulic connection with the lake. The recent draught occurrences and increased water consumption in agriculture and drinking sections water have not only caused regression of lake water, but also effected on coastal aquifer, such as Salmas plain aquifer. Over the long-term, average groundwater level in the Salmas aquifer has dropped sharply to 18/05 meters (averaging about 0/44 meters per year) and there has been 241 million cubic meters of reservoir capacity reduction. Salmas plain has two confined and unconfined Aquifers. Salmas annual depletion of groundwater resources in the study area during the water years of 2014-15 has been equal to 146 million cubic meters. The effects of land subsidence have been observed in some output areas (Kalshan and Qareh Qeshlaq areas).
