Concentrating on cultural changes is one of the most significant aims of studying archeology. The interpretation of the cultural changes in a society or a region in prehistoric periods requires a decent understanding of the relation between the cultural materials. Having a specific view or a theoretical approach towards the so-called issue reflects the researcher’s orientations. One of the cultural areas in Iran about which there have been several ideas and disputes on its prehistoric cultural changes could be the Central Plateau of Iran. Most of the proposed theories about the cultural changes of this area have been based on historical-cultural approach. In this study, we have been analyzing these changes in Tehran plain along with revision and considering the past theories together with defining theoretical concepts for presenting a new viewpoint.

Firstly, some seals from Qazvin, one from Kermanshah and the other from Zanjan will be described and compared with some similar cases in this paper. Then, the probable relations between these seals and historical issues during Iron Age III in Iran as well as trading and historical geography matters are going to be discussed. The compound elements of the local arts in Luristan (Lurestan) and some attributes of the Elamite style of seal making beside their scant differences from Assyrian art let us infer that the mentioned seals are local; however, they (the seals featured in this paper) have been influenced by the Neo-Assyrian style as a result of the substantial trading and political military interrelations between the two places (Iran and Mesopotamia).

In recent decades, climatic variables have become more pronounced, making the flow rate sensitive to these changes. This study used climatic data of 39 synoptic stations and nine hydrometric stations in the statistical period of 1994-2015 and prospective data of 2021-20 More
In recent decades, climatic variables have become more pronounced, making the flow rate sensitive to these changes. This study used climatic data of 39 synoptic stations and nine hydrometric stations in the statistical period of 1994-2015 and prospective data of 2021-2080. Maan Kendall test in MATLAB environment has been used to detect annual changes. Maan Kendall statistics, Sen's slope estimates, and coefficient variation have been used from the relevant formulas in the Excel environment. The results show that the trend of precipitation in region 1, temperature in region 7, and evapotranspiration in basin eight are increasing, and the most changes in flow sensitivity analysis to precipitation changes in region 8, the temperature in regions 3 and 8, and the results of sensitivity analysis to evapotranspiration parameter It is different. The temperature in the three scenarios studied had a significant upward trend, and the changes in precipitation were different in different regions, and the most changes in the decrease in precipitation were in regions 1 and 4.

Mitochondrial genome sequencing is one of the most used method in the mammalian phylogenetic relationships studies. Such researches mostly focus on intraspecific divergence, prioritization of protective measures, and investigation on the species origin, refugium theory and other studies. Many investigations have been focused on Gazelles in Iran and other parts. Most studies agree on the existence of three species of the Gazella genus, yet there is still much debate about the status of different populations and phylogenetic relationship of the species in different habitats. In this study, we have tried to investigate on the phylogenetic status of the genus in the central plateau populations including Yazd, Isfahan and Kerman. Our results indicated that the populations in the Yazd Province show the most phylogenetic divergence in comparing with Isfahan and Kerman populations. Our results showed that overall genetic diversity of the central plateau is relatively low. With regard to the sample size, we believe that the obtained results should be interpret with caution
