The purpose of the present study was to investigate the causal relationship between mindfulness and body image in adolescents with the mediating role of coping strategies. The research method was descriptive-correlation based on Structural equation modeling. The statistical population of the research included all high school boys students in Qaimshahr city in the academic year 2022-2023, and 300 students were selected as a sample by cluster sampling method. The tools of this research included the Multidimensional Body Self-relation Questionnaire (MBSRQ) Cash, 1985, the Way of Ciping questionnaire (WOCQ) Lazarus, 1985 and the Kentucky Inventory of mindfulness skills (KIMS) Bauer, Smith, and Allen, 2004. Structural equation analysis was used to analyze the data. The results showed the optimal fit of the research model. The results showed that mindfulness has a significant direct effect on body image (p<0.001). The direct relationship between mindfulness with a negative emotion-oriented coping style and with a positive problem-oriented coping style was significant (p<0.001). The direct relationship between an emotional-oriented coping style with a negative body image and the path coefficient between a problematic coping style with a positive body image was significant (p<0.001). The indirect relationship between mindfulness and body image through emotion-oriented coping and problem-oriented coping was positive and significant (p<0.001). It is concluded that coping strategies play a mediating role between mindfulness and body image in adolescents.

Flood is one of the natural disasters that occur due to water outburst and submersion of a significant part of the land and due to the huge damage it causes, it is necessary to know different methods of dealing with floods. This study was performed different methods of dealing with floods in Iran and the world. For this study, the required materials were collected from domestic and foreign sources and 51 methods of flood management were investigated. In this research, we have tried to take a comprehensive approach on all useful and efficient methods of dealing with floods and finally analyzing the obtained information. The results showed that investigating all methods of flood control and their recognition and how to use them is essential for researchers, and each method can be useful in effective flood reduction and damage prevention in its time and spatial scales. The results also showed that between 51 methods of flood control, 31 were related to structural methods and 20 were related to other structural methods. The results also showed that as much as possible, it is better to use non-structural methods to control floods in watersheds, and it is more economical from an environmental and economic point of view, and it creates less interference in watersheds, and if necessary, a combination of structural methods with non-structural methods should be used, and only structural methods should be avoided. The results also showed that green watershed management can be developed as a new method to deal with floods in the future and become the best and most sustainable method of flood management in Iran and the world. Therefore, it is recommended that green watershed management be seriously considered by the country's executive authorities.

Drones now have many useful functions, ranging from monitoring pipelines, photography, filming, and as hobby for teenagers. Despite diversity of civil and military uses of drones for countries, they have threats for critical infrstructures and key assets. Nowadays, they are used beside war fighter planes. Drone attacks can be done by commercial drones dropping bombs, firing a missile, or crashing into a target. One of the main concerns is the unauthorized use of drones near critical infrastructure, public events, and sensitive locations. For instance, drones flying near airports or nuclear power plants pose a serious threat to security. Unauthorized drone activities can interfere with operations, compromise safety, and even facilitate criminal acts. Furthermore, because of their high efficiency and low cost among manned planes, they are more favorate for world armies. The availability of advanced navigation and satellite communication technologies has revolutionised the use of drones, making them more versatile. They can now endure missions by 40 hours, far beyond the capabilities of human crew. With in-flight refuelling and ultra-efficient solar power, the drones can provide an even greater range of operation. Meanwhile, in order to deter drone threats, diversive actions have done in the world, called "Counter-drone technologies or systems". Counter-drone technology encompasses a wide range of ways that allow you to detect, classify, and mitigate unmanned aerial vehicles. Parallel of using drones in the world, developing of counter-drone technologies is on process. More of these technologies are based on electronic and cyber defense methods. The growth of Counter-drone technology is related to the increase in concerns about the threat that drones pose in civilian and military infrastructures. Counter drone systems have become essential for the safety and security of critical infrastructures. Counter-drone systems detect and intercept the unknown drones by taking into account their flight path, physical properties such as size and kinetic energy, the number of swarming drones, and the likely damage which could be caused. Counter-drone systems are fixed or preferably portable and have the capability of defending the facilities like military establishments and sites, airports, petroleum facilities, and etc. by quickly detecting multiple drones at sufficient distances.Drone detection technology works to detect drones in the airspace. The most popular ways to detect drones electronic and cyber defense are: acoustic sensors, electro-optical and infra-red sensors, RADAR and radio ferequency sensors. Acoustic sensors can involve one or multiple microphones and software. These technologies can detect drones by engine sound to calculate distance and direction. Optical sensors (cameras) utilize multiple wavelengths (thermal, infrared, etc.) for day or night drone detection, and the technology is evolving quickly to extend range and intelligence with AI capabilities. Radar uses radio waves to determine distance and speed of objects. It is accurate and identifies hundreds of targets simultaneously, including all drone types (piloted or autonomous) in many weather conditions. RF sensors consist of one or multiple antennas of various ranges to detect communications between and drone and its controller (human operator). Although for drone mitigation or interception, the best are electro- magnetic pulse (EMP) or high power microwave (HPM), laser guns, electromagnetic field, jamming and spoofing.This research is aimed to develop prioritized solutions of electronic and cyber defense in drone detection and defense.In this research which is applicative in nature, the most popular methods in electronic and cyber defense were identified and analyzed using of a mixed methodology after a literature review on drone detection and defense systems. Then by using of library studies and expert opinions, 12 criteria were gathered and prioritized using AHP method. These 12 criteria were: response time- cost- side effects- operator skills-ability to detect autonomous drones- range- accuracy- intensity of effect- ability to drone landing- ability to build in the country- accessibility to system details.In this process, it was known that performance accuracy and functional range of detection systems have the best points. Then each of drone detection and defense was marked and by multiplying scores in weight of each criteria, final scores of each drone detection and defense system was identified in order to prioritizing them.At last, it became clear that for drone detection based on determined criteria the best method is RADAR based method and for defense is HPM. So, using of laser systems and cyber spoofing with a slight difference were on next steps of drone defense.

A substantial body of research highlights the presence of social preferences, their economic and political implications, and the varied conditions that influence their effects on the equilibrium and outcomes of human interactions. This study utilizes data from the Global Preferences Survey (GPS) to explore how age and gender impact social preferences across Iran at both national and provincial levels. The findings from a multivariate regression analysis reveal that age positively and significantly influences trust and altruism, while it negatively and significantly impacts negative reciprocity, with no significant effect on positive reciprocity. Gender, on the other hand, shows a significant negative effect on trust, indicating that women tend to exhibit lower levels of trust. Additionally, income and education negatively and significantly impact trust but positively affect altruism and positive reciprocity, with no notable effect on negative reciprocity.
The study also presents a provincial ranking within Iran based on key elements of social preferences: trust, altruism, positive reciprocity, and negative reciprocity. According to the research findings, Iran scores above the global average in terms of altruism, trust, and reciprocity. Notably, Markazi, Lorestan, and Ilam provinces rank highest in trust, altruism, and reciprocity, respectively.

Biological fouling and microbial corrosion can significantly affect industrial cooling systems' efficiency. The study suggests that low concentrations of chlorine in seawater can be effective in inhibiting biological fouling and consequent corrosion. It highlights that chlorine interacts with components in seawater and that maintaining a residual chlorine concentration below 3 micromoles at condenser outlets is highly effective. A concise review of antifouling methods includes alternatives to chlorination and a monitoring strategy that can enhance treatments. Additionally, the review encompasses various approaches for anti-fouling methods and monitoring to improve treatments. Through electrochemical monitoring and optimized treatments, operators can uphold device performance and oversee the production of halogen-containing by-products in industrial cooling facilities.

The rapid and widespread dissemination of various types of misinformation in the field of health and on social media and online platforms has led to the emergence of health information disorders, which has brought serious threats to society. The aim of this studty is to identify actions and strategies necessary to deal with health information disorders in published literatures. The present study conducted using scoping review and searching keywords related to health information disorders in electronic databases of Web of Science, Scopus, Pubmed, Proquest, and Embase to realize the goal of identifying actions, strategies and solutions to deal with heath information disorders. After studying the content of the articles and extracting the data, the actions and solutions were identified and categorized to the health information disorders. These actions were categorized into five main themes, including verification and evaluating, provision and access to valid information sources, control and supervision. Health policy makers’ attention to these actions and strategies is expected to provide a pathway to prevent and deal with the health information disorders and to raise public awareness of future public health crises.

Many Surahs and verses of the Quran address the issue of poverty and how to combat it. The Quran places important social responsibilities on the shoulders of Muslims. As the first and most important place where the verses of the Quran were revealed, Mecca faced poverty and deprivation before and after the Prophethood. In order to become familiar with the evolution of the sources and methods of combating poverty, it is necessary to study them based on the revelation order of the Surahs of the Holy Quran. This article seeks to introduce and compare the sources and methods used in Mecca. This study was conducted using library documents, content analysis and interpretation methods. The results show that due to the spread of poverty, slavery, and hunger in Mecca, God made honoring orphans, feeding the poor, helping relatives, and helping the needy obligatory in the initial surah of the Quran, but in the later surahs, zakat, giving for a better society (infaq), known rights, charity, and interest-free lending were made obligatory as the most important resources and methods of combating poverty. Paying attention to these findings can be useful for policymaking and combating poverty both in the absence and presence of an Islamic government.

The complexity of the sea environment, external disturbances and uncertainties in the system, as well as the failure and saturation of the actuators, are effective factors in the control of underwater vehicles. In this note, to deal with the mentioned problems, a robust and adaptive controller is proposed by combining the fast terminal dynamic sliding mode controller and the radial basis neural network. In the proposed approach, the problem of actuator saturation is considered and its stability is proved using Lyapunov theory. Fix-time convergence, estimation and dealing with external disturbances and uncertainties, active dealing with actuator fault, elimination of chattering phenomenon, and non-saturation of the actuator are the advantages of the proposed controller. The designed controller is applied on an autonomous underwater vehicle and the controller parameters are optimized to achieve the least error in tracking the reference trajectories as well as the shortest convergence time. To evaluate the performance of the proposed controller, it has been compared with a passive fault control method and PID controller, which has shown the superiority of the proposed control method in tracking the desired trajectories, the amount of control effort, dealing with actuators faults and external disturbances, as well as convergence in less time.

The legitimacy of protesting against Islamic government is one of the accepted principles in Islam and the Constitutional Law of the Islamic Republic of Iran. However, if protest turns into subversion, the Islamic government has to confront it and implement divine judgment regarding the subverters. The research question revolves around the Qur’anic foundations of the necessity to confront subverters, with the hypothesis that from the perspective of the Holy Qur’ān, all those seeking to overthrow the Islamic government must be confronted. In this study, we have concluded that any type of practical and deliberate confrontation aimed at striking against the “Islamic government entity” and undermining public security is considered subversion, so, initially, the Islamic ruler, and subsequently, all people are duty-bound to confront the subverters. The aforementioned encounter in the initial stage must be conducted with utmost peace, but unfair peace based on complacency with subverters is not endorsed or divinely approved. Traditions attributing the occasion of the revelation of verses to Imam Ali’s struggle against the Nākithūn (those who broke their covenants), the Qāṣitūn (those who deviated from divine guidance), the Māriqūn (the apostate, those who became renegade by seceding from the caliph’s camp) and enemies of Imam Mahdi (May Allah hasten his noble reappearance) are all indicative of the application of a universal concept on a particular one,  and  also of the fact that the same principle applies to those who want to subvert the Islamic government with no exception. The type of punishment for the subverters is specified by law.
