In this paper, we have studied the spectral statistics of 101 even-even nuclei in the nearest neighbor spacing distribution framework. Sequences are prepared by using all the latest experimental data for 2+ levels of considered nuclei in the 40 ≥ A≥ 198 mass region. The maximum likelihood estimation technique has been used to extract the Berry-Robnik distribution’ s parameter which explores the regular or chaotic behavior of considered sequences. Sequences are classified as their mass, quadrupole deformation parameter, the energy ratio and the Shell model configuration for the last protons and neutrons of all nuclei. Our results suggest a regular dynamics for these even mass nuclei. Also, the regularity is increased for light nuclei vis-a-vis heavier ones and also the deformed nuclei vis-a-vis spherical ones. Our results show a deviation of chaotic dynamics when the spins of proton levels are decreased or the spins of neutron levels are increased.

Despite numerous studies of Shell and helically coiled tube heat exchangers, a few investigations on the heat transfer and flow characteristic consider the geometrical effects like coil pitch. Moreover, this scarcity is highlighted for the Shell side of this type of heat exchangers. This study reports experimental and Computational Fluid Dynamics (CFD) investigations on heat transfer and flow characteristics of a Shell and helically coiled tube heat exchanger. The experiments were carried out using a helically coiled tube, which was placed in a cylindrical Shell. Hot and cold water were used as the process fluids on the tube and Shell side, respectively. The CFD modeling technique was employed to describe the experimental results, fluid flow pattern, and temperature profiles as well as dead zones in the heat exchanger. Quantitative predicted results of CFD modeling show a good agreement with the experimental data for temperature. The effect of the coil pitch on heat transfer rate was numerically studied and it was found that the heat transfer coefficient intensifies with an increase in coil pitch. The average turbulent kinetic energy (k) for the old coil tube and twice coil pitch heat exchanger was computed as 2.9×10-3 and 3.3×10-3 m2/s2, respectively. This indicates an increase of about 14% in flow turbulent kinetic energy. Nusselt numbers were compared with those estimated using published correlation and a mean relative error (MRE) of 14.5% was found between the experimental and predicted data. However, a good agreement was obtained in lower Shell Reynolds numbers (lower than Re=200).

Sea Shells are natural-biological objects. They are embedded in geological layers in the form of fossils, but also, to find in archaeological deposits as a result of human activities. Archaeologists can use the provenance of Shells in the functional analysis of ancient sites in terms of social archeology and prehistoric trading activities. Aarcheological excavations in several sites of the Iranian Plateau have shown that from the 3rd third millennium B.C. onwards, finds of of sea Shells (e.g. Lambis, Dentalium, etc.) rapidely increased. Such Shells were for instance discovered from ritual cemetery contexts such as Shahdad, Tepe Hesar, Kale Nisar cemeteries or Bani Surma. These objects are mainly used as natural or polished Shells. In some cases, they served as a raw material for making all kinds of beads, buttons, and other ornamental objects.. The main question is to understand the relationship between the use of seaShells and archaeological context, and also, their role in Bronze Age ritual life. In this article, the descriptive, analytical method has been used in the biological recognition of all types of Shells. This method is also used based on similar studies on this issue in Mesopotamia's archeology of the Sumerian-Akkadian period. The distribution of recognizable species shows that these objects are concentrated in the settlements from south to southeast of Iran in the coastal strip of the Persian Gulf, and from the Oman Sea to the Zagros intermountain valleys, as well as in the northwest and northeast of Iran. The biological origin can be placed in the northern shores of the Oman Sea to the Gulf of Kutch on the northern coast of the Indian Ocean. It seems that with the growth and development of urbanization in Southwest Asia and especially the development of sea trade, oysters have been traded as valuable goods and other prestige goods. The importance of the Shell findings is more than the value of the Shells themselves because they were used as sacred goods in religious affairs. Analysis of the fields where the Shells were discovered is more related to cemeteries and temples as sacred spaces. Also, the significant presence of Lambis Shells for the production of specific ritual bowls, placed together with bronze axes in graves, can be seen as the reflection of a patriarchic tradition in the social-political organisiation of the third and second millennia B.C. Despite many excavations and the discovery of many samples of these types of Shells, no furthergoing investigation on these specific objects was undertaken so far. This desideratum reveals more valuable findings in the archeology of the Iranian plateau. Therefore, one of this article's final goals is to focus more on analyzing the context of the discovery of seaShells in future Excavation

The Nordic model has become a brand at the international political economy; the adoption of the social-democratic model has had more effects than a pure economic consequences. However, although the application of the principles of free market, innovation and free trade has brought welfare states into the industrialized world with high levels of GDP and high quality of living standards, it is this special social construction and political stability that has enabled them to experience this level of economic and social capital. This social construction and political stability is the result of the intellectual-social context of the Nordic field. Nordic universal welfare states have a system of social welfare, the provision of social and public services. Each tradition has formed a hybrid system of both the social democratic model and capitalist model in the Nordic region. The current studyaims to find how socio-cultural traditions have formulated both the formation and the solution of the difficulties and dilemmas of the Nordic model of universal welfare state. Consequently, based on a descriptive-explanatory method, this article examines the socio-cultural traditions of the Nordic society, including the free peasant tradition, the socialist utopia tradition, the capitalist and the governing tradition, and explains how to configure these traditions in principles foundations of "human development", "hybrid economy", "social capital" and "public trust", "equality", "solidarity and property" and "Nordic development model".

A B S T R A C TFrom the point of view of geo structure, the location of Khanmirza plain in the folded Zagros zone in the south of the Dena fault and the presence of piezometers protruding from the soil, the presence of springs etc. are signs of crustal movement on the surface. The purpose of this research is to use geological information, seismological information, and satellite images in order to obtain a view of the tectonic activity of the present era in the Khanmirza plain, as well as to simplify the displacement calculation, to evaluate the displacement of the earth's surface and the parameters affecting this displacement, and providing a suitable model for this plain. In this study, the displacement rate of the earth's surface for 8 years (2003-2010) was calculated using D-InSAR radar images and radar interferometry. The effective parameters of the DEM elevation layer, slope, slope direction, profile curvature, surface curvature, distance from The road, the distance from the fault, the density of the fault, and the earthquake's intensity were obtained from the GIS environment. Furthermore, multivariate regression in the SPSS environment presented the best model for this plain. In this environment, the 8-year displacement rate was considered dependent, and the rest of the parameters were considered independent variables. The results were challenged in the STEPWISE model. The results showed that among the 13 methods, the 13th method is the best regional model for calculating crustal mobility in this plain by providing the best correlation coefficient of 0.826, a determination coefficient of 0.682, an adjusted determination coefficient of 0.675, and a standard error of 99%. Moreover, the average movement in this basin is a 10 cm rise for 8 years.Extended AbstractIntroductionIn recent decades, the sudden movement towards developing quantitative geomorphology has led to progress in statistical methods and mathematical models to describe geomorphological processes. The wide scope of the work has led to the foundation of quantitative geomorphological methods useful in the interpretation and interpretation of transformational-morphological processes and in the study of active tectonic areas. The earth is a dynamic system that changes, and transformation is one of its characteristics. Almost no area on its surface has not been affected by new earth-building activities during the last few thousand years. Active land construction is changing the shape of the earth's surface.Much research has been done in Iran on tectonic evaluation with geomorphic indicators. Among the works that can be mentioned: Ramsht et al. (2013) evaluated the accuracy and correctness of geomorphological indicators using geodynamic data in the Jajroud watershed northeast of Tehran. The geomorphological indices and geodynamic data results indicate that the basin studied in this research is active in new land construction. However, the level of activity of new land construction movements is different everywhere, and the upstream areas of the basin are more active in this respect.The purpose of this research is to use geological and seismological information in a GIS environment and satellite images to obtain a view of the tectonic activity of the present era in Khanmirza plain. Also, the research focuses on simplifying the displacement calculation, evaluating the amount of land surface displacement and parameters affecting this displacement. Moreover, finally, it seeks to provide a suitable model in the SPSS environment for this plain. The innovation of this research is to evaluate the amount of displacement with non-morphological indicators and measure their relationship with crustal movements. MethodologyIn this article, geological and topographical data, Envisat satellite images, and various software such as SPSS, ARC MAP, and Envi 3.5 have been used to present a regional model for the Khanmirza basin. Results and discussionThis article was designed in five basic steps, the first of which is the preparation of GIS layers required by the region. Considering that the physiographic conditions of the basin, such as slope, slope direction, profile curvature, surface curvature, distance from the road, distance from the fault, the density of the fault, and earthquake intensity are less considered in the topic of crustal mobility, in the article we tried to use from these parameters, new relations should be defined. Their correlation level with displacement value can be obtained. For this purpose, first, all these maps were drawn in the ARC MAP environment; in the next step, with the help of 22 radar interferometry images in the Envi environment and with the help of the Sarscape plugin, the amount of displacement was calculated for 8 years. The final map of the amount of displacement was obtained in GIS Came. In the present study, radar images from 2003 to 2010 were exerted to investigate displacement rates. What can be seen from this 8-year-old map is the 33-centimeter drop of this plain in the east and south, which is marked in red, and the 59-centimeter rise of the mountains on the west side of the map, which is marked in blue.In the next step, the correlation between the displacement rate and the parameters was calculated in the SPSS environment using the Pearson method. The results show the highest correlation of the displacement rate with the fault density, slope, earthquake intensity, direction of slope and surface curvature, distance from the road, distance from the fault, profile curvature, and DEM, respectively. In the fourth step, the best displacement model of the region was presented in the SPSS environment with the help of the stepwise model. The dependent variable of the eight-year displacement rate and the independent variables include DEM elevation layers, slope, slope direction, surface curvature, profile curvature, distance from the road, distance from the fault, fault density, and earthquake intensity in the form of 9 independent variables. model 13, with the highest correlation coefficient, coefficient of determination, adjusted coefficient of determination, and standard error, was recognized as the best model. Moreover, in the last step, with the help of the formula obtained from the fourth step and the final displacement map in the ARC MAP environment, an estimated regional model map was prepared based on the indicators. ConclusionDue to the location of Iran in an active tectonic region, which is in the direct collision of two Eurasian-Arabian plates in the north-northeast direction and also in the southeast region in the indirect collision of the Indian Arabian plates, it causes movement and displacement in different proportions in the Shells, and Various parts are continental and oceanic. The location of Khanmirza plain in terms of geo structure in the folded Zagros zone and the south of Dena fault and the presence of piezometers protruding from the soil and springs and other signs of crustal movement have created a destructive effect on the level of underground water and agriculture in this plain. In this research, in order to evaluate the displacement of the earth's surface and the parameters affecting this displacement, as well as to provide a suitable model by calculating the 8-year displacement rate of the earth's surface (2003-2010) using D-InSAR radar images and radar interferometry. The amount of elevation was 59 cm, subsidence was 33 cm, and the average displacement was 13 cm. Therefore, to better understand the causes of this event, effective parameters such as DEM elevation layer, slope, slope direction, profile curvature, surface curvature, distance from the road, distance from the fault, the density of the fault, earthquake intensity were calculated on this displacement in the GIS environment. Moreover, to measure the relationship between these factors and this event in the SPSS environment, through Pearson's correlation, the value of the relationship between each parameter and displacement rate was calculated, and the highest correlation between fault density and displacement rate was obtained. Following correlation measurement with the help of multiple linear regression, a stepwise model was presented in SPSS software, and the output of this model was 13 proposed methods. The 13th method, with the best correlation coefficient of 0.826, a determination coefficient of 0.682, an adjusted determination coefficient of 0.675, a standard error of 0.0099, and a significance level of 99% among these 13 methods, is the best regional model for calculating Shell mobility. It is on the level of this plain. This map's estimated regional model of the uplift value coefficient is about 40 cm, and the subsidence value is 21 cm. Also, the average change of 10 cm elevation in this plain was calculated with this method. The results of this research can be used in different planning related to the watershed, including identifying and introducing the areas involved in the risk of earthquake and subsidence, investigating and studying underground water sources, etc. Maintaining the water balance is the most important solution to prevent land subsidence in this area, which can be achieved by controlling unlicensed wells and preventing excessive water extractionFundingThere is no funding support. Authors’ Contribution All of the authors approved thecontent of the manuscript and agreed on all aspects of the work. Conflict of Interest Authors declared no conflict of interest. AcknowledgmentsWe are grateful to all the scientific consultants of this paper

The concept of space identity with human habitation in cognitive geography has been considered in recent decades. This concept is studied in the format land-meaningfulness which is human insight in dealing with space identity and original position of community life. The land-meaningfulness has given to the meanings of human of from space identity meaning and concept that manifests it in the type of social configuration. This research has studied the faulty identity of Qazvin Baghshahr configuration with the noumenonology method and within the framework of the Isfahan school. The gardens around the configuration of Qazvin Bagshahr are a smart and astutely dam against floods. In the configuration of Qazvin Baghshahr, several bio cryptography plexsuses have maintained its sustainability and durability until today. The results of this study are presented in three statements: Some cities of Iran land – context have a faulty identity, such as Qazvin Baghshahr configuration. People of Qazvin Baghshahr configuration have kept this configuration in a sustainable way for 1000 years with the land-meaningfulness which is recognition of space identity through the division of the amount of flood water in the scrolls and documents of water division and the spatial arrangement of fields and gardens. The survival of any geographical phenomenon like Qazvin Baghshahr configuration is the result of the bio cryptographys plexsuses stability and their mechanisms during the 1000-year period.
