INTRODUCTION: The structure of the urban platform of Tehran and its physical characteristics depends on the inherent conditions and environmental thresholds in relation to changes. This study aimed to determine the natural landscapes of Tehran by two phenomena of earthquake and flood that posed the highest risk in different periods of this city. Therefore, the natural perspective of Tehran is divided into three perspectives of north, central, and south regarding the inherent features and evolutionary process. METHODS: The relationship between the perspective of Tehran based on the form and geomorphological processes and the evaluation of earthquake and flood hazards have been observed in four stages, which included data collection, data processing, calculation of indicators, and analysis of findings. The studied area was divided into three northern, central, and south urban landscapes to determine the resistance thresholds of the city according to the characteristics of topography, physiography, geology, the results of field studies and satellite images, aerial photographs, as well as paleogeomorphological research in Tehran. FINDINGS: According to the zoning map of Tehran based on the earthquake phenomenon in three perspectives of north, center, and south, the highest distribution of non-resistance is observed in the northern and southern areas of the city. Northeast, southwest, and semi-western regions have the highest urban resilience to earthquakes. Moreover, regarding the zoning of Tehran based on the flood phenomenon in the three perspectives of north, center, and south, the highest distribution of non-resilience has been observed in the northern regions of the city. Northeast, southwest, and west of Tehran have the highest urban flood resilience. CONCLUSION: Based on the results of the present study, in order to increase resilience against the risks of earthquakes and floods, the city of Tehran should be studied not in just one perspective but in different perspectives.

Heart disease pretends great danger to people, as heart disease has recently become a dangerous disease that acts as a threat to humans. It usually affects all groups from young to old. The biggest challenge in this paper is data pre-processing and discovering a solution to the failure of records Clinical heart, where an effective high-performance model is proposed to enhance heart disease and treat failure in the clinical heart failure records. The current authors applied the techniques of clustering with k-means, expectation-maximization clustering, DBSCAN, support vector clustering, and random clustering herein. Using cluster techniques, we gained good enough results for significantly predicting and improving the performance of heart disease. The goal of the model is a suggestion of a reduction method to find features of heart disease by applying several techniques. Our most important results are to predict faster and better. It indicates that the proposed model is excellent and gives excellent results. This model demonstrated a great superiority over its counterparts through the results obtained in this research. We obtained some values of 130, 980, 183, 125.133, 133, 203, and 125.800. It confirms that this model will predict significantly and improve the performance of the data that we have worked on this.

INTRODUCTION: The major events occurring in recent decades have demonstrated that human societies are constantly affected by disasters which have always posed a threat to people's lives and properties. The present study aimed to introduce and expand the concept and capacities of "the survival vehicle" in Iran. This descriptive case study was conducted based on an applied research design. METHODS: This descriptive case study was conducted based on an applied research design. The library research method was used to develop theoretical backgrounds, and to collect information, the field method was employed with observation and researcher's information. FINDINGS: Considering that rescue forces have to be present at the scene of the disaster for consecutive days and weeks, they are directly exposed to threats, injuries, shortages, and problems as affected people are. Therefore, rescue experts and the Rapid Reaction Team of the Red Crescent Society of Kurdistan Province embarked on designing and using a vehicle called "Survival vehicle" taking into account the priorities in the affected area. This vehicle maintains the strength and motivation of relief forces by meeting their basic needs. Moreover, it increases the productivity of the relief forces and facilitates disaster management by strengthening the resilience of relief workers. CONCLUSION: As evidenced by the results of the present study, the use of the survival vehicle brings about numerous positive advantages for the members of the Red Crescent rapid response team, as well as relief and operational teams, at the time of crises.

Purpose: Cell homeostasis is an essential factor in maintaining cellular health and intracellular mechanisms, which can also be associated with inflammatory factors and increased stress for muscle cell health. Calcium is also a necessary factor in cell health and is to establish homeostasis in the body . This study aimed to investigate the effect of high-intensity training on serum calcium levels in combat women. Method: For this purpose, 18 women karateka in the age range of 17 to 23 years were randomly divided into 2 groups: control (n=7) and exercise ((n=11). The exercise group performed proper exercises to improve karate and aerobic techniques for 6 weeks in the intensities of more than 80% of the maximum heart rate reserve.  Physiological indices and blood samples were measured 24 hours before and 48 hours after the training protocol.  To measure calcium cell biomarker, the Pars Azmoon calcium kit was used.  Research data were analysed by covariance test at the significant level (P≤0.05) using SPSS software version 25 . Results: After six weeks of high-intensity training, there was a significant difference in serum calcium levels in the exercise group compared to the control group (P = 0.002).  Also, the results within the group showed a significant increase in serum calcium (P = 0.016) in the exercise group compared to baseline conditions. Conclusions: High intensity training seems to increase serum calcium in female athletes, and this can lead to precursors to cellular disorders, muscle damage and increase inflammatory factors and ultimately decrease the performance of female athletes. However, more research is essential in this regard .
