In ancient Iran, in addition to defensive elements such as castles, fortresses, and fortifications, there were underground cities called dastkand. These cities had a shelter-protection function and provided safe space to protect residents when enemies attacked. In the scope of dastkand architectural studies, form typology, land-use typology, and provision of thermal comfort have been investigated in various studies but there is no study on dastkand defensive architecture, which is the main purpose of the present research. The research method is a mixed method (qualitative-quantitative). The required data are collected through a survey and then, analyzed using factor analysis in R method. The statistical population includes Iranian architectural heritage specialists and the sample size is estimated to be 165 persons. Sampling adequacy is confirmed based on the results of KMO test. The samples are selected using a non-probability sampling method. The obtained results indicate that ten factors have been effective in the architecture of Iran’s ancient organic shelters. In order from largest to smallest coefficient of variance, the factors include collective defense, multi-layered defense, environmental camouflage, path control, self-sufficiency, secret passage, sustainable architecture, residential values, covert surveillance, and cluster development.

In this study, commercial biaxially oriented polypropylene （BOPP）, polyvinyl chlo- ride （PVC） and poly （methyl methacrylate）（PMMA） films were treated with nitrogen plasma over different exposure times in a Pyrex tube surrounded by a DC variable magnetic field. The chemi- cal changes that appeared on the surface of the samples were investigated using Fourier transform infrared （FT4R） spectroscopy and attenuated total reflectance Fourier transform infrared （ATR- FTIR） spectroscopy after treatment for 2 min, 4 min and 6 rain in a nitrogen plasma chamber. Effects of the plasma treatment on the surface topographies and contact angles of the untreated and plasma treated films were also analyzed by atomic force microscopy （AFM） and a contact angle measuring system. The results show that the plasma treated films become more hydrophilic with an enhanced wettability due to the formation of some new polar groups on the surface of the treated films. Moreover, at higher exposure times, the total surface energy in all treated films increased while a reduction in contact angle occurred. The behavior of surface roughness in each sample was completely different at higher exposure times.

The salt domes of the west Zanjan (Central Iran) are the most important structures in the study area. They have been formed by the uplifting and erosion together under low humidity and dry and warm climate condition. The salt rocks with near to 200 meters thickness are related to lower member of the Upper Red Formation (Early Miocene) that deposited in the inverted back arc basin. They have been formed in the Central Iran basin after the Arabian-Eurasian convergence. Based on filed works and preparation of geologic map, salt domes have been cropped out during regional uplifting and erosion along hinge zone of a longitudinal anticline. Also, there is no evidence for salt diapirism and so, they are different from some salt diapirs in the southwestern margin of Zanjan that is investigated by other researchers.
