Mathematical models can be described as a description of a system with mathematical language. This is done by introducing the system under study with a series of equations. Interpreter equations of the system are obtained based on the laws governing that system, boundary conditions, initial conditions and physical properties of the system under study. These models make it easier and faster to investigate the effect of various parameters on the system response. Once the mathematical model of a system is obtained, they can be solved analytically or numerically depending on the complexity of the equations. If the model presented is valid for a range of real numbers assigned to variables, it will be a continuous model, and if the model is valid for specific numbers in a range and for all real numbers in that range, it will be a model will be discrete. If the system does not respond to changes in time, the proposed model is called permanent. If the passage of time affects the response of the system, the proposed model is called a non-sustainable model.

Evaluating the master’s degree program in Sports Physiotherapy in order to improve the quality of education in this field. The need to pay attention to the effectiveness and efficiency of the education and improving the system of higher education by becoming more aware of the factors involved is necessary. The aim of this study is to evaluate the educational program for master’s degree in Sports Physiotherapy. This is a hybrid study in which qualitative and quantitative methods for data collection were used. The research team consisted of faculty members and sports physiotherapy students. In the first part of the study, due to a lack of standard questionnaires, the method of an expert panel was used to build the tools. In the second part, the questionnaire was distributed among 22 professors and students, and the data was collected. The findings showed that according to the viewpoints of the faculty members and students, the courses in the program are necessary and facilitates the students to become qualified in meeting their future professional requirements. The findings of other research indicate the desirability of the content, implementation, and educational facilities of the program from the viewpoint of the professors, and unfavourable from the viewpoint of the students. Moreover, from the perspective of the professors and students, the teaching methods is appropriate to the type of course and there is no need to add a new course to the program. The findings of student evaluation methods showed that these methods were considered to be favourable from the viewpoint of the professors, and unfavourable from the viewpoint of the students. As a result, the program of Sports Physiotherapy was evaluated, in terms of its favourability, with the existing courses. Nevertheless, the addition of practical and clinical units helps to improve the quality of the curriculum.

Pregnancy is a period of deep hormonal and metabolic changes that the body endures for a relatively short period of time, during which many changes occur in the skin, nails and hair. Rashes and skin changes are extremely common during pregnancy. Due to the specific mental and emotional conditions of pregnant women, these changes can cause concerns that may be related to appearance, the possibility of recurrence in subsequent pregnancies, potential effects on the fetus, or a combination of them. The skin changes observed during pregnancy are not all of the same importance. Some of them are common skin changes that can be seen in almost all pregnant women. Of course, there are a number of skin diseases that are specifically associated with pregnancy. Also, pregnancy can aggravate or alleviate many skin diseases that are not specific to this period.

This study investigated the effects of Covid-19 on body postures. Specialists around the world are now conducting clinical trials and research to understand why some patients recovering from Covid-19 have long-term complications. The coronavirus primarily affects the respiratory system and can cause pneumonia and endanger human life. Other research shows that the disease can cause blood clots and inflammation in many parts of the body, and even in mild cases. Covid-19 can also be seen. This indicates the great need to take care of yourself against the disease. The recovery time from Covid-19 disease varies from person to person. Many people feel better in a few days or weeks, and most will recover within 12 weeks, but in some people, the symptoms may last longer. The likelihood of long-term symptoms does not appear to be related to how the disease occurred when you first contracted the coronavirus, and people who have experienced mild Covid-19 may also have long-term symptoms. The corona virus, especially its newer form, the delta corona, does not only attack the lungs; The heart, kidneys, brain, arteries, nerves, and skin are other organs that have been shown to affect the function of a new mutation in the Covid-19 virus.

By studying the morbidity of surgery conducted by surgery physicians’ surgery ward at Rasool Akram hospital, we wanted to reduce morbidity cause and take a little step in improving the patient's health. Method: Medical records of patients operated in rasool akram hospital was investigated and information such as surgery, intraoperative and postoperative complication associated v variables were recorded in the check list. Result: Re-laparotomy possibility in Men was 3.5 times more than women Metastatic pathology likely increases the necessity of re-laparotomy to 1.2. The possibility of re-laparotomy in a patient who has a history of positive chemotherapy increase up to 2.9. The possibility of re-laparotomy in case of prolapse increases to 2.4 (1.8-3). Conclusion: The possibility of re-laparotomy increases with factors such as male gender, metastatic pathology, positive history of chemotherapy, the incidence of prolapse and incidence of adhesion. Although having Gl anastomosis increases the risks of post op complications and being problem with the colostomy leading to its closure are such important issues in predicting relaparotomy chances.

Nature tourism or hiking is one of the types of mountaineering, the definition of hiking is: long walks and going to places with difficult paths in nature for recreation or exercise, according to the report of the official statistics center of Iran in the spring of 2018 187,772,940 Local travel without staying overnight was done for sightseeing and entertainment. Considering the nature of Iran, this sport has attracted the attention of various people from the society, in this research, it is tried to improve the quality of nature climbing by providing innovative solutions and with the help of technology. The current research is included in the category of applied research, the sampling method in different parts of the research is the voluntary non-probability method and the research population includes people aged 20 to 45. To achieve the objectives of the research, double diamond method was used, the research stages were carried out in two phases, the first phase included the collection of theoretical information including the literature review , similar products in the market analyses , review of standards, and the second phase of data collection The design was collected through persona compilation, conducting interviews and field observations. Finally, the final checklist for the design was compiled and idea generation was done with the brainstorming method, the selected idea was evaluated and selected with the AHP method, and a prototype was made and improved during four stages of user testing. The final product is a smart wearable that is designed for less than one day nature travel, the main function of which is to carry nature travel equipment in addition to providing information related to vital and environmental signs, this product was named Hamnavard.

Heat exchangers are used as the most important equipment to transfer the energy of materials to each other, to increase or decrease the energy level of material flows. The purpose of this research is to optimize and estimate costs for re-boiler, one of the leading units of National Petrochemical Industries Company. This heat exchanger is in the form of a plate, which is used as a re-boiler for tower 511. In this research, ASPEN PLUS and ASPEN EXCHANGER DESIGN & RATING software were used to design and estimate costs. This design is based on the conditions required to set up tower 511 of methanol to propylene conversion unit. Based on the designs, the required area for the converter was 2.6 square meters, which compared to the previous converter, we had an increase of about 8% in the area for heat exchange.
