The objective of this study is to design and explain a model of electronic customer relationship management (E-CRM) aimed at increasing customer loyalty in private banks in Iran.  

This applied research employed a descriptive-survey method, incorporating both qualitative and quantitative approaches. A Delphi panel consisting of 35 experts from private banks contributed to identifying key E-CRM variables. In the quantitative phase, a sample of 384 bank managers and senior experts participated through a questionnaire. Structural equation modeling and PLS software were used for data analysis, ensuring a robust model fit and validation through reliability tests like Cronbach's alpha. 

The study identified critical influencing factors for E-CRM, categorized into human, technological, and organizational components. The model showed significant positive impacts on customer satisfaction and loyalty, with technological factors like IT management being the strongest predictors. Customer interaction, value creation, and organizational readiness for change also demonstrated notable influences. The findings support the integration of technological advancements and customer-centric approaches in private banking. 

The developed E-CRM model effectively enhances customer satisfaction and loyalty in the private banking sector. By focusing on human, technological, and organizational factors, private banks can improve long-term relationships with their customers, fostering increased loyalty. These insights highlight the need for continued investment in customer relationship technologies and staff training for optimal E-CRM performance.

To study the mechanisms that cause thunderstorms in Kerman province, we used daily data from 10 synoptic stations in the area. The thunderstorm event codes were extracted from stations as the current weather conditions (WW) every three hours to reach the goals. In the following, a single day as a representative was examined and analyzed to study the nature of the atmospheric structure. In the selected period, hail is due to the formation of a low-pressure chalk layer (500 hPa), low-pressure, and instability at the surface. Investigating the atmospheric patterns showed that the cause of this phenomenon in the study area is the strengthening and expansion of low-pressure systems in the East of the Red Sea and Saudi Arabia. These low-pressure systems have gained moisture through the southern seas (Persian Gulf and Oman Sea), causing instability and precipitation along their path. Also, cold air loss from the middle atmospheric layers causes unstable currents and hail. After examining atmospheric conditions through unstable indicators, we tried to track the storm and its formation in 24 hours. Results showed that the CAPE Index and the Total Index are effective tools for monitoring and forecasting thunderstorms in the area. on the other hand, the sweat index also helps expand and route unstable systems

The death of Sultan Mohammad Seljuqi in 511 A. H was the beginning of the weakening of the Seljuqs and the efforts of the Abbasid caliphs to strengthen the worldly power. These conflicts led to many disagreements and conroversies between the Seljuqs of Iraq and the Abbasid caliphs. The internal disagreements among the Seljuk princes caused the caliphs to seize the opportunity to consolidate their power and encourage the decentralization of the military commanders. For example, Caliph Al-Rashed Belleh, relying on the legacy that came to him from his father (Mostarshad), made great efforts to get out of the control of the Seljuqs of Iraq. The present research, written through the descriptive-analytical method relying on primary sources, seeks to investigate the relations between the Abbasid caliphs and the Seljuqs of Iraq and the policy of the caliphs to gain power. The findings of the research declare that the Abbasid caliphs managed to stregthen their authority in Iran by creating division among the Seljuk princes, alliance with Atabakan and weaker princes,   considering the prevailing conditions in Iran at the end of the 6th century A. H which led to the emergence of Khwarazmianan, and benefiting from the extra-regional forces, they ended the political life of the Seljuks of Iraq.

One of the significant issues in rural tourism is the extent of development and establishment of ecolodges as a key and fundamental indicator, as well as the spatial distribution of these accommodations. Therefore, the objective of this study is to identify and analyze the spatial and temporal changes related to the development and establishment of ecolodges across the country of Iran.

Design/methodology/approach: 

This study is applied research conducted within a quantitative research framework. The statistical population consists of ecolodges nationwide, analyzed at both national and provincial levels, as well as in the two time periods of 2002 and 2022. The required data was collected from the Statistical Center of Iran, and data analysis was performed using spatial analysis techniques in the ArcMap software environment.

The findings of this research indicate a significant increase in the number of ecolodges nationwide from 2002 to 2022. Specifically, the number of ecolodges has increased by more than 4.5 times over this period. At the provincial level, only three provinces experienced a decrease in the number of ecolodges, while all other provinces showed an increase. Furthermore, the spatial distribution of ecolodge development reveals that the highest development and density of ecolodges are concentrated in the northern and central regions of the country, whereas the lowest development is observed in the western regions.

The development and establishment of ecolodges across the country have not been evenly distributed and commensurate with the capacities and tourist attractions of each rural region. In some areas, the development of ecolodges has exceeded the capacities of tourist attractions, while in others, this ratio is below the capacities of rural tourist attractions. To achieve a more balanced development of ecolodges nationwide, it is necessary to develop and implement effective guidelines and regulations.

Originality/value: 

Existing studies on ecolodges have primarily been conducted as case studies and at a local spatial scale. The novelty of this research lies in its comprehensive and nationwide examination of the spatial distribution and establishment of ecolodges, a topic that has not been previously addressed. The findings of this study can serve as a valuable guide and roadmap for policymakers and planners.

Iran's higher education policies in non-profit higher education institutions were evaluated from political development indicators. This study was conducted on 1029 managers and faculty members of non-profit higher education institutions in Tehran, Iran, who were selected by random sampling. Based on Cochran's formula, 280 managers and faculty members of non-profit higher education institutions were selected as the statistical sample of the research. The results showed that higher education policies have a 33% ability to predict political development in the studied institutions, and the remaining 67% is related to other factors and variables. Communication with industries and financial institutions (beta= -0.23) as the most predictive power, scientific development (beta= 0.22), internationalization of education (beta= 0.21), and university goals and mission in line with development (beta= 0.19) could affect political development. A flexible organizational structure with a beta coefficient of 0.15 could not predict the political development of institutions. Based on the results, the T value of the relationship with industries and financial institutions was higher than other variables and had a more favorable situation.

This paper proposed a control system for the battery charger of a solar vehicle. The battery charger has two parts, boost converter and isolated DC/AC/DC converter. The boost converter is controlled by a proposed control system based on sliding mode. In this controller, the MPPT is implemented by an extreme point of the solar cell P-V curve. Also, the control system of the DC/AC/DC converter is based on sliding mode with consideration of uncertainties of the output filter. A fast charging algorithm based on variable frequencies was carried out by the presented control system and charging of a Lithium-ion battery was done during 20 min from SOC 20% to SOC 80%. The simulation results show control system effectiveness.

Carbon dioxide, as a great part of greenhouse gases, stands as a major contributor to climate change; hence, various techniques have been presented for controlling and decreasing CO2 emissions. The studies show that the adsorption and conversion into environmentally benign substances are the most practical and efficient strategies for this purpose. As amines are active in CO2 adsorption, N-(2-aminoethyl)-3-aminopropyltrimethoxysilane was chosen as an amine group to functionalize MCM-41 mesoporous in order to hydrate CO2 and convert to calcium carbonate in this study. The synthesis of the mesoporous materials and amine functionalization were carried out using the wet impregnation method, and the materials were characterized by XRD, FT-IR, SEM, and BET analysis. The results demonstrated a high adsorption capacity (165 mg CaCO3) due to the presence of the -NH2 group in the catalysts. Moreover, the results have been compared with similar mesoporous materials functionalized with metals for CO2 capture and hydration. The adsorption-desorption isotherm corresponded to type IV, as defined in the IUPAC classification.

Main Part:In this article, we provide a new definition of M-metric space. By presenting the topology of this space, while examining some of its properties, we show that the limit of a sequence is not necessarily unique. In the following, by defining a new topology, we state that it is weaker than the previously defined topology.Detail:In1994 in [1] Matthews introduced the notion of a partial metric space and proved the contraction principle of Banach in this new framework. Next, many fixed-point theorems in partial metric spaces have been given by several mathematicians.In this paper, we extend the p-metric space to an M-metric space, and we shall show that our definition is a real generalization of the p-metric by presenting some examples.

Abdolhossein Teymourtash was one of the prominent statesmen of the first Pahlavi period who played an important role in the political, social and economic developments of that period. Have been studied by many researchers, his efforts in establishing the Pahlavi dynasty and his important role in creating new reforms in the government structure. In the research, there are different opinions about the performance and character of Teymourtash. The confusion in Teymourtash᾽s actions and the lack of a clear conceptual framework to analyze his personality were among the factors that have made it difficult to understand Teymourtash. The present article tries to explain Teymourtash᾽s personality type by choosing Enneagram personality typology, with considering all personality and historical issues and paying attention to the historical context. The current research method used the historical method in gathering information and in the development and analysis of the material, the authors tried to use the method of interdisciplinary studies and conduct research with a historical-psychological approach. According to the present research, the personality of Abdolhossein Teymourtash is formed in the form of the eighth type of the Enneagram and as a constructive and power-seeking leader, which some actions and based on the types of relaxation and tension and wings the eighth brigade can be explained conflicts in his actions.

In recent years, convexity theory has experienced rapid development. Many researchers have expanded it. A notable generalization of the convex function is the Inox function introduced and studied by Hanson. This has greatly expanded the role of inox in optimization. Ben and Mond introduced a class of functions called generalizations of pre-Inox functions. Regarding change inequalities and related problems in recent years, Pite and Postloche introduced the concept of pseudo pre-invex, and applied it in theoretical mechanics and nonlinear optimization. Later, Pite and Antchak introduced this concept of invex, and applied it to vector optimization. This shows that pre-invexity plays an important role in the development of various fields of pure and applied sciences. In this article, we first introduce the concept of  -pre-inox and then state and prove the Hermit-Hadamard theorem for it, and we will state that the previously obtained inequalities are a direct result of our main theorem. In this article, we first introduce the concept of  invex sets and  pre-invex functions. Then state and prove the Hermit-Hadamard theorem for it, and state that the previous inequalities are a direct result of our main theorem. Quantum calculus is known as the study of differential and integral calculus without restrictions. Euler (1783-1707) was the first to study quantum calculus. He introduced q in Newton's infinite series compositions. In the early 20th century, the study of quantum calculus was started by Jackson. In quantum computing, we obtain mathematical equivalents of q objects that can be recovered as . Note that quantum calculus is a subset of time scale calculus. The time scale of calculus provides a unified framework for the study of dynamical equations in both discrete and continuous domains. That in quantum calculus, we deal with a specific time scale called the q time scale. Quantum calculus is a bridge between mathematics and physics. Due to the significant applications of quantum computing in mathematics and physics, this issue has been the focus of many researchers. As a result, quantum calculus has emerged as a fascinating field. In recent years, convexity theory has experienced rapid development. Many researchers have expanded it. A notable generalization of the convex function is the inex function, which was introduced and studied by Hanson [1]. This has greatly expanded the role of inox in optimization. Ben and Mond [2] introduced a class of functions called generalizations of pre-invex functions.This fundamental result of Hermit and Hadamard (HH) has obtained by many mathematicians, and as a result, this inequality has been extended by Noor in various ways using new ideas and obtained the Hermit-Hadamard inequality for pre-invex functions. Regarding variational inequalities and related problems in recent years, Pite and Postloche [3],[4]  and [5] introduced the concept of pseudo pre-invex, and applied it in theoretical mechanics and nonlinear optimization. Later, Pite and Antchak [6] introduced this concept of inexity, and applied it in vector optimization. This shows that pre-invex plays an important role in the development of various fields of pure and applied sciences. For more details on the quantum calculus see references [7].MethodNo method applicable. In This article, we improve the Hermite-Hadamard (HH) integral inequality for  - preinvex functions.Assuming , Theorem 3.1 of the article [8], that is, relation (3) is obtained. Assuming , the main theorem of the article [9] and  and , Hermit Hadamard's main inequality is obtained.

Reference evapotranspiration (ET0) is the maximum amount of water transpiration for a particular vegetation cover (such as grass, alfalfa, or a standard crop area). FAO 56 report emphasis, is on measuring meteorological parameters at a height of two meters above green grass. Cultivation around the station should be on a wide area and there is no shortage of water. Agricultural meteorological stations covering a certain territory around them record the same meteorological conditions as the surrounding plants. The Penman-Monteith-FAO (PMFAO) equation was proposed to calculate ET0 and the use of alternative method was not recommended. In the present research, the Hargreaves-Samani (HS) method and the PMFAO method were evaluated on daily, Monthly and yearly time steps in the ZayandehRud basin over a period of 25 years from 1995 to 2019. The results showed that in the daily time step, the difference between the two methods is large (Nash coefficient from 0.63 to 0.87). In the monthly time step, the difference is generally negligible (Nash coefficient from 0.8 to 0.96). In annual time step (Nash coefficient above 0.8), the results are very close to each other. But in different stations, the same behavior was not seen, for example, in Kabutrabad station, in contrast to East Isfahan station, almost always, ET0 by HS method is higher than PMFAO. Therefore, in practice, to use ET0 by HS method, it is recommended to verify and evaluate at least with the nearest synoptic station and PMFAO method and then use it.

Attention to Ardabil province is one of the important centers of wheat cultivation, determining the level of cultivation will be of particular importance in economic and political planning and can ensure the country's food security, but in the past, most traditional methods, such as field measurement, etc., have been used to determine the level of crop cultivation, which has many errors, In this study, we tried to use Landsat 8 satellite imagery, Vegetation Indices (NDVI, SAVI, DVI, GVI, IPVI, RVI), Principal components analysis (PCI), Optimum Index Factor (OIF), and classification algorithm to estimate the maximum probability of wheat cultivation area in the study area. Based on the results of main components analysis, more than 99% of data variances were explained in three main components and the best color combination of the OIF index was determined by bands 5, 6, and 7 with a numerical value of 8383.73. Also, the results showed that wheat cultivars under cultivar 94-95 in the studied area with kappa coefficient is 0.87 and the general accuracy of 95.2% were 59203.07 hectares and According to the statistics of agricultural Jahad official in Ardebil province, which is about 62480.21 hectares, In other words, the difference is 5.24% or about 3277.14 hectares which seem to be acceptable. Therefore, it can generally be concluded that Landsat 8 images, Principal components analysis, and Optimum Index Factor are highly effective in determining the level of wheat cultivation.

In recent years, cyberspace has been filled with cyber attacks such as denial of service (DoS) attacks, information phishing, financial fraud, spam and so on. One of the most common cyber attacks that have caused significant economic damage to the financial infrastructure of different countries is denial of service attacks. As a preventive measure, intrusion detection systems equipped with machine learning classification algorithms have been developed to detect anomalies in network traffic. These classification algorithms, depending on the type of DoS attack, have varying degree of success in detecting these attacks and allow users to effectively identify between normal traffic and malicious DoS traffic. In the proposed approach, three steps are used to identify and classify the most common denial of service attacks. The first step is to pre-process the actual SNMP-MIB dataset to scale the data and delete the defective data. In the second stage, by reducing the number of data set features, only the features of the interface group are used, which leads to a reduction in attack detection time. The results show that using the proposed approach, normal traffic and five DoS attacks can be detected from the MIB-SNMP dataset with 100% accuracy rate. Only the detection accuracy of two attacks, UDP Flood and Slowloris, with 99.87 and 99.94% respectively, had a very small error of detection rate.

Radiology and photography films are mainly made of silver halides, which are very sensitive to light. The developer-fixing solution reduces silver salt crystals and turns them into black metallic silver on film and a stable and clear image appears on the film. After several uses of the fixing solution, its efficiency is reduced due to the decrease in the concentration of sodium thiosulfate and finally, it cannot be used since there is not enough awareness regarding its harm, so it enters the environment through wastewater. In this study, the recovery of fixing solution waste has been investigated. The recovery of the solution waste, silver extraction, and direct synthesis of nanoparticles have been performed by chemical reduction method from the waste. The obtained samples were analyzed and studied by EDX, XRD, and SEM techniques. The results showed that the fixing solution waste and silver metal were recovered properly with a purity of 99.81%. Also, AgNPs were synthesized by chemical reduction. Recovery of the fixing solution waste -for the first time- and metallic silver, as well as the synthesis of AgNPs by chemical reduction method, is an economical method and free of any contamination.

The unbalance currents injection by power electronic transformers in order to improve the unbalance voltage conditions of the network causes an imbalanced voltage in the DC link capacitors and creates an active powers inequality in the different phases. In this paper, the proposed control structure independently controls the active power of each phase by modifying the power angle between the voltages of the grid and transformer. Based on the presented analytical relations, the amplitude and phase of the desired zero component current can be calculated. The power angle variations in the different phases of the first stage create a zero-sequence current by the proposed control system which is equal to the result of analytical relations. The simulation results in two modes of the voltage imbalance and network fault show that by injecting the improvement negative currents, the active powers and the DC voltage of capacitors are significantly affected so these Divergences limit the transformer improvement capacity and create vulnerabilities for DC capacitors. After applying the proposed control method, proper convergence is created in the powers flow and DC capacitors voltage. Experimental results also show the convergence of these parameters after applying the proposed control method. Also, the conformity of the zero component by the proposed control structure with the calculated values from the presented analytical relations is clearly visible from the laboratory results.

In this paper, after introducing the $m$-convexity by Toader, as an intermediate among the general convexity and star shaped property, we bring Hermite-Hadamard integral inequality on $(\alpha,m)$-convex function in the new form. Previous results about the Hermite-Hadamard inequality for $m$-convex functions are part of the results of our theorems. Illustrated examples of $(\alpha,m)$-convex and $m$-convex functions are also included in the article.

Determining the water requirement of agricultural products is one of the most important ways to achieve water management efficiency. Therefore, the main purpose of this study is to estimate the water requirement of corn in Meshginshahr, Ardabil province. For this purpose, 10 cloudless images of Landsat 8 satellite from 2004 to 2016 and the SEBS method were used. The results were compared with Penman-Monteith and evaporation pan methods. The results showed that in the SEBS method the water requirement of corn crop on 2010.8.3was equal to 8.14 mm/day and on 2015.11.30 equal to 1.09 mm/day and in Penman-Monteith method on 2013.7.19 equal to 9.94 mm/day and on 2015.11.30 equal to 3.12 mm/day, which has the highest and lowest actual evaporation and transpiration, respectively. SEBS method has the highest error rate with RMSE equal to 1.466 and MAD equal to 1.325 mm/day compared to evaporation pan. SEBS method has the lowest error rate with RMSE equal to 1.199 and MAD equal to 0.947 mm/day compared to the Penman-Monteith method. Also, by examining the values of the coefficient of determination, it was found that the SEBS method has the highest coefficient of determination (0.8677) with the Penman-Monteith method and then with the evaporation pan method (0.8247).

Aquaponic is considered a sustainable semi-closed system for food production that combines aquaculture and hydroponics. The aims of this study were to evaluate the influence of aquaponic on the growth and feed performance, digestive enzyme activity and blood parameters of Common carp juveniles for 60 days. This experiment consisted of three groups (three replications per group) which included; cultivation of common carp without plants (T0), use of aquaponic system for culturing common carp with lettuce (TL) and cucumber (TC). A total of 225 carp (initial body weight: 11.59 ± 0.41g) were randomly distributed in nine 60-L tanks. Results showed that aquaponic system in TL and TC groups could increase the weight gain (WG) and specific growth rate (SGR) and reduce the feed conversion ratio (FCR) of common carp. Total protease, amylase, and lipase activities were also significantly higher in TL and TC groups than control group, respectively. After 60 days, serum lysozyme activity and total immunoglobulin were significantly higher and serum cortisol and glucose levels were lower in aquaponic groups than the control group. The highest serum catalase and superoxide dismutase were observed in TL and TC group. The best effect on growth, digestive enzymes, and immune response were shown in TL and TC groups (Aquaponic system) compared to control.

In recent studies in Iran, arsenic anomalies have shown in excess of the WHO standard (10 ppb) in water resources that the use this water has irreparable effects on human health. Therefore, it is necessary to offer a solution for reducing the arsenic anomalies. In recent years, nanoparticles have been used to reduce the arsenic concentration in water resources at syntheses samples. However, the performance of these nanoparticles to reduce the arsenic concentration in groundwater resources, which generally have different complexes, has not been investigated. In this study, iron oxide nanoparticles have been used to reduce the arsenic anomalies from groundwater resources. Previous studies on iron oxide nanoparticles have been to isolate arsenic added in the laboratory, but the main challenge of this study is the separation of arsenic from groundwater sample. The results of investigation the effective various parameters such as pH, temperature, filtration time and the adsorbent amount on the separation of arsenic from groundwater showed that the highest separation is the temperature conditions above ambient temperature, low pH, time 5 to 15 minutes and the adsorbent amount 0.3 g. Finally, Sugeno fuzzy model was used to simulate and model the process of removing arsenic pollutants from groundwater sources. The fuzzy model results showed this model is very efficient for approximate prediction of arsenic adsorption by iron oxide nanoparticles with NRMSE = 0.03 and R2 = 0.8.

In this study, MCM-41, SBA-15, and that modified nanoporous materials were used for absorption of Pb2+ and Cd2+ ions from water. Nano-porous materials properties are characterized by XRD, BET, SEM, and FT-IR, and also, Pb2+ and Cd2+ ions concentration measurements by AAS. According to BET analysis for SBA-15 and NH2- MCM-41 samples, the shape of both sample isotherm is IV type. In this study, the parameters of adsorbent amount, pH changes, and absorption time were investigated. The results show Pb2+ absorption efficiency is more than Cd2+ absorption by synthesized samples. Also, the presence of the amine group in the structure increases the absorption efficiency. Repeatability of absorption by both samples was performed in four steps and the results show that absorption does not change much, which confirms the repeatability of adsorbents. Also, The X-ray diffraction pattern of the SBA-15 sample shows that the structure is retained after the absorption process.

Data and information from the Meteorological Department of India and the Joint Hurricane Warning Center (JHWC) were used to investigate the structural nature of Ashuba tropical storm in the Arabian Sea from June 7 to June 12, 2015. To study the atmospheric structure, the analyzed digital data were taken from the European Center for Medium-Term Forecasts and the Center for Environmental/Atmospheric Forecasts (NCEP/NCAR) for the Arabian Sea and beyond. The study area was the Arabian Sea, located between the Indian subcontinent (eastern part) and the Arabian Peninsula (western part) and northwest of the Indian Ocean. On average, 1-2 tropical cyclones form on the Arabian Sea each year. Even in some tropical regions, strong cyclonic cycles occur at the synoptic scale (Evan & Camargo, 2001: 145). Therefore, from previous years, climatologists have studied the types of storms, due to the increase in tropical cyclones in the last decade; and thereby, this issue is followed with more sensitivity. Consequently, the main purpose of this study was to explore the structural nature of Ashuba tropical storm on the Arabian Sea in order to identify one of the region's main moisture sources.

Storm data statistics were obtained from the Meteorological Department of India and the Hawaii Hurricane Warning Center. Analyzed digital data, including; Geopotential altitude (Hgt), orbital (u), meridional wind (v), sea surface pressure (SLP), air temperature and sea water temperature (SST) for standard levels at 17 compression levels with a resolution of average daily geographic degree belonged to the National Center for Environmental Prediction/Atmospheric Science and precipitated networked data were obtained from the European Center for Medium-Term Atmospheric Forecasting (ECMWF) with a resolution of 0.125 degrees Celsius for the Arabian Sea. NASA and MODIS satellite imagery were also used for the visible band for every six days. The CAPE index was applied to evaluate the energy required by the storm supplier.

The results of study displayed that in the middle level of the atmosphere, while forming a low-altitude nucleus with very strong positive rotation, the conditions for the production of tropical storms in the region have been provided. On the other hand, on the surface, low pressure has formed in the southeast of the Arabian Sea with a central pressure of 995 hPa and has started moving westwards towards the coasts of Oman and northern Yemen. Creating a very strong convergence current on the surface and upper divergence caused the storm to reach its maximum strength in the region on June 9. However, the anomalous temperature of the water surface in the range where the storm reached its maximum intensity reaches to over than 5 degrees Celsius. The increase in water surface temperature and the transfer of heat and moisture into the storm has strengthened and, by its nature, caused heavy rainfall in the region. Finally, on June 12, as it approached the east coast of Oman, it began to disappear due to lack of moisture for its dynamic movements, and changed from a tropical storm to a tropical hurricane. Also examining the prepared maps for the amount of precipitation and the flow of the lower levels of the atmosphere, it was determined that on the first day of the storm, a cyclonic current occurred in the east of the Arabian Sea, resulting in the maximum amount of precipitation in the west of the system, which reaches more than 240 mm. On the second day, moving north of the system, the amount of precipitation was concentrated in the south, so that the southern coast of India was not unaffected by precipitation and had about 120 mm of rainfall. On the third day, with the placement of this tropical storm in the north of the Arabian Sea, the maximum precipitation was created in the east of the system, which was more than 160 mm. On the fourth day, the western half of the Indian coast was faced with a rainfall of nearly 110 mm, which was due to its location in the east of the cyclone, which in turn caused the rise of air and the transfer of moisture to the air parcel, floods in the region. On the fifth day, the maximum rainfall was close to the eye of the storm, which was close to 100 mm, and the coastal areas of the Indian subcontinent were still experiencing heavy rainfall. Examination of the 850 hPa pressure system revealed that on the first day, the maximum relative pressure system nucleus formed in the southeastern parts of the Arabian Sea. These conditions have led to very strong convergence in the lower levels. The presence of such strong convergence and amplification of rotation has caused this anomaly to reach its maximum in the region. The strong rotating nucleus then extended to the west coast of India and then moved westward on the third day to the central regions of the Arabian Sea, with a very strong rotating current extending from latitudes 10 to 30 degrees north. As the storm/hurricane approached the west coast of the Arabian Sea, it intensified to more than five pressure system units on the fourth day. On the fifth day, the positive nucleus became independent and formed a very strong rotating closed cell. On the sixth day, with the cyclone remaining on the eastern coast of the Arabian Peninsula, its power had gradually diminished.Considering the water temperature in the region, which is an average of 6 days, it showed that the water temperature in most parts of the Arabian Sea was high, so that these conditions reached more than 32 degrees Celsius in the coasts of India and the center of the Arabian Sea. These conditions were less only in the northern regions of the sea than in other regions. To understand the water surface temperature, its anomaly was also calculated for six days with the storm. Its output indicated that the eastern, northern, western and southwestern regions of the Arabian Sea were associated with a positive anomaly of 2 to 3° C. Negative anomalies only reached -1.5 degrees Celsius in the north and south of the sea. Occurrence of maximum positive anomalies in the region was one of the main reasons for the intensification of cyclones in the region, so that the western regions of the Arabian Sea had the maximum positive anomalies and on the other hand the maximum area of ​​tropical cyclone activity.The 12-hour reports from the Indian Meteorological Agency and the Hawaii Hurricane Warning Center were used to route the tropical storm. In these two centers, there were several data methods for routing and the origin of the storm. Geographical coordinate data with a 12-hour separation was used, which from the beginning of the storm to its decline, its characteristics and longitude and latitude were recorded as a text file. The onset of the storm was from the eastern part of the Arabian Sea, which migrated northward to higher elevations and deviated in its path due to the dominance of the Coriolis to the west of the region and disappeared off the coast of Oman.

Ashuba tropical storm/hurricane formed on June 7, 2015 in the Arabian Sea and disappeared on June 12, 2015. This investigation revealed that on the first day, a low-lying cell was formed in the eastern part of the Arabian Sea, during which a positive rotating nucleus or vortex was formed in the mentioned area and strengthened in the following days. The role of the Arabian Sea and abnormal changes in its water surface temperature in the occurrence of hurricanes has been mentioned in the researches of Ghavidel Rahimi (2015: 31) and Lashkari and Kaykhosravi (2010: 19). On June 9, as the subtropical anticyclone expanded further east, the Arabian Sea's low-pressure cell became oval in a circle, contributing to the deepening of the system, creating another bond at the heart of the closed cell with a height of 5,810 geopotential meters. In the last days, as the coasts of Oman and Yemen approach, the intensity of this cell decreases and its extinction stage was reached. On the surface, in parallel with the mentioned period, a low-pressure core with a central pressure of 995 hPa formed on the southeast of the Arabian Sea and the creation of a very strong positive rotation indicates the occurrence of hurricanes in the region. The central pressure of the storm reached less than 993 hPa on days 9 and 10, which was the peak of the storm. As it approached the shores, the intensity of this cyclone was greatly reduced, turning it from a tropical storm into a tropical turbulence. Examination of the water surface temperature showed that the average water surface temperature in these 6 days in most parts of the Arabian Sea was more than 29 degrees Celsius. Inspection of water surface temperature anomalies also disclosed that the maximum positive anomalies corresponded to several places in the sea, including the southern coasts of Pakistan to western India, eastern Oman and a very strong core corresponding to the southwest of the Arabian Sea with an average temperature of more than 5° C. The maximum rainfall inside the cyclone indicated that on the first day of the storm, the maximum rainfall in the southwest was 240 mm. In the following days, with the transfer of this core to the south, southeast and finally to the east, the maximum rainfall would be on the west side of the Indian coast. Only in the last days it was observed that while the maximum rainfall occured in India near the eastern part of the eye of the storm, a maximum precipitation center with an average of 100 mm has been created. In this study, two indicators, CAPE and SWEAT, were used to assess the location of storm formation. The results showed that these two indicators well showed the formation and severity and weakness of the storm during different stages. Thus, on the first day in the south of the Arabian Sea, the amount of CAPE was more than 5000 Jules/kg, which indicates the amount of convective energy available. On the other hand, the values ​​of the SWEAT index have reached more than 380, which specify that the probability of a hurricane in this region is very high. Also, with the increase of water surface temperature in the region and the increase of anomalies in it, the necessary energy is provided for the production of cyclones in the region, which with the increase of energy within the air mass system and the presence of buoyancy energy in it, and on the other hand, instability indicators in monitoring and tracking these types of storms showed that they are a suitable tool for tracking and are able to navigate it while being aware of the intensity of the storm.

Although pain is one of the most common symptoms of diseases, it is often mismanaged due to limited access to painkillers and ineffectiveness, unacceptable side effects, or the possibility of abuse. However, an alternative approach to existing analgesics is to indirectly increase endogenous pain relief pathways by neprilysin (an enkephalinase) inhibitors. This enzyme breaks down and inactivates enkephalin, dynorphin, endorphins, and their derivatives.

In this project, a new series of racecadotril-tetrazole-amino acid derivatives 15a-l was synthesized and characterized on the basis of IR, 1H and 13C NMR, mass spectrometry, and elemental analysis. The antinociceptive activity of synthesized compounds was assessed by a hot plate, tail-flick, and formalin assays in mice. Docking was used to identify the possible interactions between neprilysin and synthesized compounds.

Most of the synthesized compounds showed moderate to good analgesic effects in hot plat and tail-flick test in comparison to morphine and racecadotril. Compounds 15l and 15j were the most potent compounds. The synergistic analgesic effect of compounds 15l and 15j with morphine and the antagonistic effect of naloxone on the activity of these compounds confirm that the analgesic effect of compounds 15l and 15j could be mediated through the opioidergic system. The negative and high binding energy of docking simulation of the most potent compounds in the catalytic site of neprilysin was also in good agreement with the inhibitory activity of test compounds.

Racecadotril-tetrazole-amino acid derivatives, as potential antinociceptive agents, demonstrated moderate to good antinociceptive activities comparable with morphine and higher than racecadotril.

To evaluate the flesh quality of fingerling common carp reared in aquaponics culture system, fish with cucumber and lettuce was reared under the aquaponics system for 60 days with three treatments including cultivation of common carp without plants (T0), an aquaponics system for culturing common carp with lettuce (TL), and cucumber (TC) each with three replications. For the meat quality evaluation of reared fish, at the final rearing period after harvesting fish, chemical composition, fatty acid profile, color, texture profile analysis, and sensory assessment were determined. The result showed that protein and lipid content in T0 and TC were significantly higher than in TL (P<0.05). Most of the sum monounsaturated fatty acids (∑MUFA) and polyunsaturated fatty acids (∑PUFA) were recorded in TC and T0, respectively. Lipid quality base on the atherogenic (AI) and thrombogenic (TI) indices in TL was higher than in TC. According to color indices, fish skin in T0 and TL exhibited similar lightness and transparency, higher than in Tc. The color of fish muscle in TC displayed redness higher than in the other treatments. In case of texture profile analysis, springiness in TC was significantly higher compare to the other treatments. In case of sensory assessment, the score of odor attribute in TC was significantly lower compare to the other treatments. In conclusion, the muscle quality in the fish reared under aquaponics culture system was more acceptable in comparison with that in T0 (common carp reared without the plants) and in case of fish reared under aquaponics system, those reared with cucumber revealed better quality than the lettuce.

A change in the structure of the education system that began with the enactment of new laws from the time of the constitution and gradually continued; with the change in the structure of government during the first Pahlavi era and the adoption of new policies, it underwent extensive practical changes. The centralist policy of the new government put the entire educational structure of the country under the control of the government. In line with such an approach, the city of Kerman underwent extensive reforms in the field of education, both quantitatively and qualitatively. Despite significant achievements in this field, the province and the city of Kerman suffer from a lack of funding. In this regard, the study of the consequences of budget deficit in the education structure of Kerman is the focus of the present study. Findings of the research, which has been done with a historical method and with an analytical approach based on library sources and newly found documents, show that despite the extensive educational achievements in the structure of education in Kerman, factors such as limited financial resources and a small amount of Annual government budget; It caused the changes made not to fit the needs of the existing education system.
